Technical Field

The invention relates to a storage device and a refrigerator with the storage device, belonging to the field of household appliances.

Background technique

Refrigerator storage devices, such as drawers, fresh-keeping boxes, storage boxes, bottle holders, etc., generally have a large storage cavity.

Example 1

1 to 6 c , this embodiment provides a storage device 100 , which includes a body 11 , a pair of guide mechanisms 12 , a first partition frame 132 , a second partition frame 131 and an adjustment assembly 14 .

The body 11 forms a substantially rectangular accommodating cavity 10 with an upper opening, and the accommodating cavity 10 is used to store various storage objects, such as food, beverages, etc. The body 11 includes a bottom wall, a pair of first side walls 11a disposed opposite to each other, and a pair of second side walls 11b disposed opposite to each other. The bottom wall is used to carry storage objects, and the pair of first side walls 11a and the pair of second side walls 11b extend vertically upward from the bottom wall respectively.

In order to clearly express the position and direction described in this embodiment, the direction defined by the relative position of the pair of first side walls 11a is defined as the front-to-back direction (also called the longitudinal direction), and the direction defined by the relative position of the pair of second side walls 11b is defined as the left-to-right direction (also called the transverse direction). That is, the pair of first side walls 11a are arranged relative to each other in the front and back directions, and the pair of second side walls 11b are arranged relative to each other in the left and right directions. In addition, the plane defined by the front-to-back direction and the left-to-right direction is defined as the horizontal plane, and the direction perpendicular to the horizontal plane is defined as the vertical direction.

Referring to Fig. 1 and Fig. 2, a pair of guide mechanisms 12 are respectively arranged on a pair of second side walls 11b. The guide mechanism 12 comprises a guide rod 12a, a guide member 12b and a fixing seat 12c, wherein: the guide mechanism 12 is fixed to the body 11 through the fixing seat 12c, and the fixing method between the fixing seat 12c and the body 11 can be threaded connection, riveting, snap connection, etc.; the guide rod 12a is parallel to the second side wall 11b and extends forward and backward; the guide member 12b is sleeved on the guide rod 12a and can slide forward and backward along the guide rod 12a. When the guide mechanism 12 is fixed to the body 11, the guide member 12b can and can only slide forward and backward relative to the body 11.

The first partition frame 132 is accommodated in the accommodating chamber 10 and can be used to divide the accommodating chamber 10 into front and back. Specifically, the first partition frame 132 includes a partition, which is horizontally placed in the accommodating chamber 10 to divide the accommodating chamber 10. The vertical surface where the partition is located defines the dividing surface of the first partition frame 132, and the accommodating chamber 10 is divided into front and back with the dividing surface of the first partition frame 132 as the boundary. In this embodiment, the partition includes partition cross bars 132a and 132b arranged in the shape of long rods, and the partition cross bars 132a and 132b extend left and right and are arranged at intervals in the vertical direction.

The first partition frame 132 further includes a pair of connecting members 132c. The connecting members 132c connect the end of the partition cross bar 132a and the end of the partition cross bar 132b, and together with the partition cross bars 132a and 132b, form a rectangular frame.

The first partition frame 132 is connected to the body 11 by the guide mechanism 12 to slide forward and backward, so as to adjust the size and/or number of storage partitions formed by the front and rear division of the accommodating chamber 10. Specifically, the first partition frame 132 includes a pair of fixing portions 132d formed at the left and right ends of the first partition frame 132, and each fixing portion 132d is connected to a corresponding guide member 12b. When the guide member 12b slides forward and backward along the guide rod 12a, the first partition frame 132 slides forward and backward in the accommodating chamber 10 synchronously.

The fixing portion 132d and the guide member 12b are plugged into each other. The fixing portion 132d is specifically configured as a long rod, and its extension direction is perpendicular to the extension direction (left-right direction) of the partition crossbars 132a and 132b; the guide member 12b includes a mounting hole 12d that matches the fixing portion 132d, and the fixing portion 132d can be plugged into the mounting hole 12d along its extension direction. When the fixing portion 132d is inserted into the mounting hole 12d, the fixing portion 132d and the mounting hole 12d limit each other in the left-right direction, so that the fixing portion 132d cannot move left-right relative to the guide member 12b; a pair of guide members 12b limit the first partition frame 132, so that the first partition frame 132 cannot move left-right relative to the body 11, thereby enhancing the stability of the first partition frame 132.

The outer surface of each guide member 12b is abutted against the corresponding second side wall 11b, so that when the first partition frame 132 has a tendency to move leftward or rightward relative to the main body 11, one guide member 12b can limit the movement tendency of the first partition frame 132 to the left by abutting against the corresponding second side wall 11b, and the other guide member 12b can limit the movement tendency of the first partition frame 132 to the right by abutting against the corresponding second side wall 11b.

In this embodiment, the guide mechanism 12 is disposed outside the body 11 away from the accommodating cavity 10, specifically, outside the corresponding second side wall 11b. The inner side of each guide member 12b is respectively abutted against the corresponding second side wall 11b, thereby enhancing the stability of the guide member 12b when sliding, and preventing the first partition frame 132 from shaking left and right relative to the body 11 during use.

A guide groove 11c extending forward and backward is provided on each second side wall 11b. The left and right ends of the first partition frame 132 pass through the guide groove 11c and are connected to the guide mechanism 12. Specifically, the fixing portion 132d passes through the guide groove 11c from the accommodating cavity 10 and is connected to the mounting hole 12d of the guide member 12b.

In this embodiment, the extension direction of the fixing portion 132d is parallel to the extension direction of the guide groove 11c, that is, the fixing portion 132d also extends along the front-to-back direction. In this way, it can not only prevent the first partition frame 132 from shaking left and right relative to the main body 11 during use, but also facilitate the removal of the fixing portion 132d from the guide member 12b, thereby facilitating the assembly and disassembly of the first partition frame 132.

Further, the guide member 12b includes a first guide member 121b and a second guide member 122b which are separately arranged, and the first guide member 121b and the second guide member 122b are detachably assembled and connected. The mounting hole 12d is arranged on the first guide member 121b, and the first guide member 121b and the second guide member 122b surround a channel 12e, and the channel 12e is connected to the mounting hole 12d. When the first guide member 121b and the second guide member 122b are separated, the fixing portion 132d can be inserted into the mounting hole 12d from between the first guide member 121b and the second guide member 122b, and then the first guide member 121b and the second guide member 122b are assembled and connected, so that the second guide member 122b limits the fixing portion 132d to prevent the fixing portion 132d from being separated from the mounting hole 12d.

Referring to FIGS. 1 to 3 , the second partition frame 131 is accommodated in the accommodating chamber 10 and can be used to divide the accommodating chamber 10 into left and right parts. In this embodiment, the second partition frame 131 is rotatably connected to the first partition frame 132 around the vertical axis t through the adjustment component 14. According to the positional relationship between the second partition frame 131 and the first partition frame 132, the storage device 100 has a stacked state (see FIG. 1 ) and an unfolded state (see FIG. 3 ). By setting the second partition frame 131 to be rotatably connected to the first partition frame 132, the number of storage partitions formed by dividing the accommodating chamber 10 can be adjusted, thereby increasing the flexibility of dividing the accommodating chamber 10.

The second partition frame 131 includes a separator, which can be used to divide the accommodating cavity 10, and the vertical plane where the separator is located defines the dividing surface of the second partition frame 131. The lateral width of the accommodating cavity 10 (that is, the distance between a pair of second side walls 11b) is greater than the longitudinal width of the accommodating cavity 10 (that is, the distance between a pair of first side walls 11a), and accordingly, the width of the dividing surface of the first partition frame 132 is greater than the width of the dividing surface of the second partition frame 131, that is, the length of the partition is greater than the length of the separator.

In this embodiment, the separator includes partition longitudinal rods 131a and 131b which are arranged in the shape of long rods. The partition longitudinal rods 131a and 131b are parallel to each other and arranged at intervals in the vertical direction.

Referring to FIG. 1 , when the storage device 100 is in the stacked state, the partition surface of the second partition frame 131 is coplanar with the partition surface of the first partition frame 132, and the partition longitudinal rods 131a, 131b and the partition transverse rods 132a, 132b extend in the left-right direction and are located in the same vertical plane, so that the occupied space of the second partition frame 131 can be reduced when idle, while increasing the neatness and aesthetics; referring to FIG. 3 , when the storage device 100 is in the unfolded state, the second partition frame 131 and the first partition frame 132 are cross-arranged, and the accommodating cavity 10 can be arranged with the first partition frame 1 The accommodating cavity 10 can be divided into front and back parts by the dividing surface of the second dividing frame 132, and the accommodating cavity 10 can be divided into left and right parts by the dividing surface of the second dividing frame 131. At this time, the dividing surface of the second dividing frame 131 has a non-zero angle with the dividing surface of the first dividing frame 132. In the present embodiment, the dividing surface of the second dividing frame 131 is perpendicular to the dividing surface of the first dividing frame 132. Specifically, the dividing longitudinal rods 131a and 131b extend in the front-to-back direction, the dividing transverse rods 132a and 132b extend in the left-to-right direction, and the dividing longitudinal rods 131a and 131b are perpendicular to the dividing transverse rods 132a and 132b.

Further, the partition also includes a glass partition 133a, and the partition 133a can be selectively assembled between the partition crossbar 132a and the partition crossbar 132b by the user through the first fixing member 133b and the second fixing member 133e. Wherein, the partition 133a is assembled to the connecting member 132c through the first fixing member 133b, and is detachably connected to the adjustment component 14 through the second fixing member 133e. By setting the partition 133a, the stored items in the storage partitions on the front and rear sides of the first partition frame 132 are not in contact with each other, so as to avoid odor contamination and prevent the stored items from sliding across between the partition crossbar 132a and the partition crossbar 132b. Of course, in a variable embodiment, the partition 133a may not only be located between the partition crossbar 132a and the partition crossbar 132b, but may also partially extend upward to above the partition crossbar 132a, and/or partially extend downward to below the partition crossbar 132b.

In the vertical direction, the partition longitudinal rod 131a and the partition longitudinal rod 131b are arranged adjacent to each other, and the partition longitudinal rod 131a is always higher than the upper boundary of the partition (in this embodiment, the partition transverse rod 132a), and the partition longitudinal rod 131b is always lower than the lower boundary of the partition (in this embodiment, the partition transverse rod 132b). The partition longitudinal rod 131a, the partition transverse rod 132a, the partition board 133a, the partition transverse rod 132b, and the partition longitudinal rod 131b are arranged in sequence in the vertical direction. In this way, when the storage device 100 is in the stacked state, the second partition frame 131 will not interfere with the partition board 133a.

Furthermore, the second partition frame 131 can also be slidably connected to the first partition frame 132 through the adjustment component 14, that is, the second partition frame 131 can both slide and rotate around the vertical axis t relative to the first partition frame 132, so as to adjust the number/size of storage partitions formed by dividing the accommodating cavity 10 as needed.

Among them, the above-mentioned second partition frame 131 is slidably connected to the first partition frame 132 through the adjustment component 14, and there are multiple implementation methods: first, the first partition frame 132 is non-slidably connected to the adjustment component 14, and the second partition frame 131 is slidably connected to the adjustment component 14, so that the size/number of storage partitions formed by the accommodating chamber 10 being divided front and back by the first partition frame 132 can be adjusted; second, the first partition frame 132 is slidably connected to the adjustment component 14, and the second partition frame 131 is non-slidably connected to the adjustment component 14, so that the size/number of storage partitions formed by the accommodating chamber 10 being divided left and right by the second partition frame 131 can be adjusted; third, as in the present embodiment, the first partition frame 132 is slidably connected to the adjustment component 14, and the second partition frame 131 is also slidably connected to the adjustment component 14, so that the size/number of storage partitions formed by the accommodating chamber 10 being divided front and back by the first partition frame 132 and the storage partitions formed by the accommodating chamber 10 being divided left and right by the second partition frame 131 can be adjusted, and the flexibility is higher.

4a to 5, the specific structure of the adjustment component 14 is described in detail. In this embodiment, the adjustment component 14 is configured as a cylindrical structure mirror-symmetrical along a horizontal plane q. Of course, in a modified embodiment, its shape and structure are not limited to this embodiment.

The adjustment assembly 14 includes a first adjustment mechanism and a second adjustment mechanism. The first adjustment mechanism is matched with one of the first partition frame 132 and the second partition frame 131, and the second adjustment mechanism is matched with the other of the first partition frame 132 and the second partition frame 131. In this embodiment, the first adjustment mechanism is matched with the first partition frame 132, and is set to two, namely, the first adjustment mechanism 142a matched with the partition cross bar 132a and the first adjustment mechanism 142b matched with the partition cross bar 132b; the second adjustment mechanism is matched with the second partition frame 131, and is also set to two, namely, the second adjustment mechanism 141a matched with the partition longitudinal bar 131a and the second adjustment mechanism 141b matched with the partition longitudinal bar 131b; the first adjustment mechanism 142a matches the second adjustment mechanism 141a, and the first adjustment mechanism 142b matches the second adjustment mechanism 141b.

The first adjustment mechanism 142a includes a third component 43a, a fourth component 44a and a first channel 145a. The third component 43a includes two hooks 434a and a groove 433a; the fourth component 44a includes two grooves 441a and a groove 442a; the two hooks 434a correspond to the two grooves 441a one by one and are snap-fitted, so that the third component 43a and the fourth component 44a are assembled and connected to each other; the first channel 145a is formed between the third component 43a and the fourth component 44a, and is specifically surrounded by the groove 433a and the groove 442a, so as to facilitate the assembly and connection of the first adjustment mechanism 142a and the partition crossbar 132a. The first channel 145a is for the partition crossbar 132a to pass through, so that the first adjustment mechanism 142a slides along the partition crossbar 132a.

Similarly, the first adjustment mechanism 142b is assembled with the partition crossbar 132b, and its specific structure refers to the first adjustment mechanism 142a, which will not be repeated here. The first channel 145a is parallel to the first channel 145b, and the adjustment component 14 is slidably connected to the first partition frame 132.

The second adjustment mechanism 141a includes a first component 41a, a second component 42a and a second channel 144a. The first component 41a includes two hooks 411a and a groove 412a; the second component 42a includes two grooves 421a and a groove 422a; the two hooks 411a correspond to the two grooves 421a one by one and are snap-fitted, so that the first component 41a and the second component 42a are assembled and connected to each other; the second channel 144a is formed between the first component 41a and the second component 42a, and is specifically surrounded by the groove 422a and the groove 412a, so as to facilitate the assembly and connection of the second adjustment mechanism 141a and the partitioning longitudinal rod 131a. The second channel 144a allows the partitioning longitudinal rod 131a to pass through, so that the second adjustment mechanism 141a slides along the partitioning longitudinal rod 131a.

Similarly, the second adjustment mechanism 141b is assembled with the partitioning longitudinal rod 131b, and its specific structure is referred to the second adjustment mechanism 141a, which will not be described again. The second channel 144a and the second channel 144b are parallel, and the adjustment assembly 14 is slidably connected to the second partition frame 131.

Furthermore, the first adjusting mechanism 142a includes a matching column 432a, and the second adjusting mechanism 141a includes a matching hole matching the matching column 432a; the matching column 432a and the matching hole of the second adjusting mechanism 141a can be plugged in and matched along the vertical direction, and the two have cylindrical matching surfaces that match each other, so that the first adjusting mechanism 142a and the second adjusting mechanism 141a are matched and can rotate relative to each other around the vertical axis t. In this embodiment, (taking the main body 11 as a reference) the second adjusting mechanism 141a rotates around the vertical axis t. Similarly, the second adjustment mechanism 141b includes a matching hole 424b, and the first adjustment mechanism 142b includes a matching column matching the matching hole 424b; the matching hole 424b and the matching column of the first adjustment mechanism 142b can be plugged in and matched along the vertical direction, and the two have cylindrical matching surfaces that match each other, so that the first adjustment mechanism 142b and the second adjustment mechanism 141b are matched and can rotate relative to each other around the vertical axis t. In this embodiment, (taking the main body 11 as a reference) the second adjustment mechanism 141b rotates around the vertical axis t.

Furthermore, when the coupling post 432a and the coupling hole of the second adjustment mechanism 141a are coupled, the two are mutually limited, so that the relative displacement of the first adjustment mechanism 142a and the second adjustment mechanism 141a in the horizontal direction is limited, thereby avoiding shaking. Similarly, when the coupling hole 424b and the coupling post of the first adjustment mechanism 142b are coupled, the two are mutually limited, so that the relative displacement of the first adjustment mechanism 142b and the second adjustment mechanism 141b in the horizontal direction is limited, thereby avoiding shaking.

In this way, the first adjusting mechanism 142a, 142b and the second adjusting mechanism 141a, 141b are rotated relative to each other to drive the first partition frame 132 and the second partition frame 131 to rotate relative to each other around the vertical axis t, so that the storage device 100 is switched between the stacked state and the unfolded state.

Specifically, the adjustment assembly 14 further includes a cam structure, which is formed between the first adjustment mechanism and the second adjustment mechanism. In this embodiment, the number of the cam structures is set to two, namely, a cam structure 143a formed between the first adjustment mechanism 142a and the second adjustment mechanism 141a, and a cam structure 143b formed between the first adjustment mechanism 142b and the second adjustment mechanism 141b. Of course, in a modified embodiment, only one of the cam structure 143a and the cam structure 143b may be set.

Taking the cam structure 143a as an example, the specific structure of the cam structure is introduced (the specific structure of the cam structure 143b refers to the cam structure 143a and will not be repeated). The cam structure 143a includes a first concave-convex curved surface 431a with a full-circle wavy shape formed on the upper end surface of the first adjustment mechanism 142a and a second concave-convex curved surface 423a with a full-circle wavy shape formed on the lower end surface of the second adjustment mechanism 141a. The first concave-convex curved surface 431a and the second concave-convex curved surface 423a are adapted to each other; and when the first adjustment mechanism 142a and the second adjustment mechanism 141a rotate relative to each other around the vertical axis t, the second concave-convex curved surface 423a and the first concave-convex curved surface 431a abut against each other, so that the first adjustment mechanism 142a and the second adjustment mechanism 141a perform a reciprocating jumping motion away from or close to each other in the vertical direction.

The cam structure 143a has at least two lowest point meshing positions (see FIG. 4a and FIG. 4c) where the second concavoconvex curved surface 423a and the first concavoconvex curved surface 431a are concavoconvexly matched with each other, and a highest point abutting position (see FIG. 4b) where the second concavoconvex curved surface 423a and the first concavoconvex curved surface 431a are convexly abutted with each other. When the cam structure 143a moves from the lowest point meshing position to the highest point abutting position, the first adjustment mechanism 142a and the second adjustment mechanism 141a move away from each other in the vertical direction; when the cam structure 143a moves from the highest point abutting position to the lowest point meshing position, the first adjustment mechanism 142a and the second adjustment mechanism 141a move closer to each other in the vertical direction.

When the second partition frame 131 rotates relative to the first partition frame 132 around the vertical axis t, taking the process of the storage device 100 changing from the stacked state to the unfolded state as an example (the process of the storage device 100 changing from the unfolded state to the stacked state is the opposite, which will not be repeated):

Referring to FIG. 4a , when the storage device 100 is in the stacked state, the adjustment assembly 14 is in the first engagement state, at which the first channels 145a, 145b and the second channels 144a, 144b are parallel, and accordingly, the partition surface of the first partition frame 132 is parallel to the partition surface of the second partition frame 131, and the cam structures 143a, 143b are both in the lowest engagement position;

Referring to FIG. 4b , when the storage device 100 switches from the stacked state to the unfolded state, in the process of the adjustment component 14 changing from the first meshing state to the critical state, the cam structures 143a and 143b both move from the lowest meshing position to the highest abutting position, and the first adjustment mechanism 142a and the second adjustment mechanism 141a move away from each other in the vertical direction, and the first adjustment mechanism 142b and the second adjustment mechanism 141b move away from each other in the vertical direction; until the adjustment component 14 is in the critical state, the cam structures 143a and 143b are both in the highest abutting position; then, in the process of the adjustment component 14 changing from the critical state to the second meshing state, the first adjustment mechanism 142a and the second adjustment mechanism 141a move closer to each other in the vertical direction, and the first adjustment mechanism 142b and the second adjustment mechanism 141b move closer to each other in the vertical direction;

Referring to FIG. 4c, when the storage device 100 is in the unfolded state, the adjustment assembly 14 is in the second engaged state, at which time the first channels 145a, 145b and the second channels 144a, 144b are perpendicular to each other, and correspondingly, the dividing surface of the first partition frame 132 is perpendicular to the dividing surface of the second partition frame 131, and the cam structures 143a, 143b are both in the other lowest engagement position.

Furthermore, the cam structures 143a and 143b are both configured as a circumferentially divided structure, that is, when the cam structures 143a and 143b are switched between two adjacent lowest meshing positions, the first adjustment mechanism 142a and the second adjustment mechanism 141a are relatively rotated 90° around the vertical axis t, and the first adjustment mechanism 142b and the second adjustment mechanism 141b are relatively rotated 90° around the vertical axis t. Furthermore, the second partition frame 131 is relatively rotated 90° around the vertical axis t relative to the first partition frame 132, so that the storage device 100 switches between the stacked state and the unfolded state, completing a flipping cycle.

At the same time, when the cam structures 143a and 143b change between the lowest meshing position and the highest abutting position, the first adjustment mechanism 142a and the second adjustment mechanism 141a rotate 45° relative to each other around the vertical axis t, and the first adjustment mechanism 142b and the second adjustment mechanism 141b rotate 45° relative to each other around the vertical axis t.

Furthermore, when the cam structures 143a and 143b are not in the lowest engagement position, the adjustment component 14 is always subjected to an elastic driving force that drives the cam structures 143a and 143b to move to the lowest engagement position, that is, the elastic driving force drives the first adjustment mechanism 142a and the second adjustment mechanism 141a to have a tendency to approach each other in the vertical direction, and the first adjustment mechanism 142b and the second adjustment mechanism 141b to have a tendency to approach each other in the vertical direction.

In this embodiment, the elastic driving force is provided by the second partition frame 131. Specifically, the second partition frame 131 is made of a rigid material, and further includes a pair of connecting rods 131c connecting the ends of the partition longitudinal rod 131a and the ends of the partition longitudinal rod 131b; the fourth component 44a and the fourth component 44b are integrally formed, the fourth component 44a is set as the upper half of the structural member 44, and the fourth component 44b is set as the lower half of the component 44, so that the first adjustment mechanisms 142a and 142b are fixedly connected in the vertical direction. When the cam structures 143a and 143b are in the lowest meshing position, the second partition frame 131 has no elastic deformation, and its partition longitudinal rods 131a and 131b are parallel to each other and have an initial spacing; when the cam structures 143a and 143b are not in the lowest meshing position (including being between the lowest meshing position and the highest abutment position and being in the highest abutment position), driven by the second adjustment mechanisms 141a and 141b, the local spacing of the partition longitudinal rods 131a and 131b close to the adjustment component 14 is greater than the initial spacing, and the ends maintain the initial spacing under the pulling of the connecting rod 131c, so that the second partition frame 131 undergoes elastic deformation, and the elastically deformed second partition frame 131 applies the elastic driving force on the adjustment component 14.

In this way, during a flipping cycle when the storage device 100 switches between the stacked state and the unfolded state: under the action of an artificial external force, the second partition frame 131 rotates relative to the first partition frame 132 around the vertical axis t, the adjustment component 14 changes from the first meshing state to the critical state (or from the second meshing state to the critical state), the cam structures 143a and 143b both move from the lowest meshing position to the highest abutting position, and the second adjustment mechanisms 141a and 141b move away from each other in the vertical direction, driving the second partition frame 131 to undergo elastic deformation; when the adjustment member 140 is adjusted, the second adjustment member ... When the component 14 reaches the critical state, the cam structures 143a and 143b are both in the highest point abutment position, and the elastic deformation of the second partition frame 131 reaches the maximum; after crossing the critical state, under the action of the elastic restoring force of the second partition frame 131, the second adjustment mechanisms 141a and 141b approach each other in the vertical direction, and the adjustment component 14 changes from the critical state to the second meshing state (or from the critical state to the first meshing state), thereby transforming the storage device 100 from the stacked state to the unfolded state (or from the unfolded state to the stacked state).

Of course, in a variation of the embodiment, the storage device 100 may further include an elastic member providing the elastic driving force, wherein the elastic member is disposed between the first adjusting mechanism and the second adjusting mechanism, and when the cam structure is not in the lowest engagement position, the elastic member undergoes elastic deformation.

Furthermore, the connecting rod 131c is arranged to be non-coplanar with the partition longitudinal rods 131a and 131b. When the storage device 100 is in the stacked state, a pair of connecting rods 131c are close to the partition cross rod 132a and the partition cross rod 132b and are respectively located on the front and rear sides of the first partition frame 132.

Compared with the prior art, the storage device 100 of this embodiment can adjust the number/size of storage partitions formed by dividing the accommodating cavity 10 as needed, for example, through the movement of the first partition frame 132 and/or the second partition frame 131, a zero partition as shown in Figure 6a, a two-partition as shown in Figure 6b or Figure 1, a four-partition as shown in Figure 3, or by disassembling and replacing the second partition frame 131, a three-partition as shown in Figure 6c is formed; and the first partition frame 132 is easy to disassemble and assemble, and has good stability during use; the storage partitions formed by the first partition frame 132 can avoid cross-falling.

Of course, in a modified embodiment, the first adjustment mechanism may be provided as one, and its upper and lower ends are respectively connected with one second adjustment mechanism; or, two second adjustment mechanisms are provided to be fixedly connected in the vertical direction, and two first adjustment mechanisms are provided separately, and when the adjustment component changes from the first meshing state to the critical state, the two first adjustment mechanisms move relatively close to each other in the vertical direction. These changes do not deviate from the technical purpose of the present invention.

Example 2

7 to 9 c , this embodiment provides a storage device 200 , which includes a body 21 , a pair of guide mechanisms 22 , a first partition frame 232 , a second partition frame 231 , and an adjustment assembly 24 .

The body 21 forms a substantially rectangular accommodating cavity 20 with an upper opening, and the accommodating cavity 20 is used to store various storage objects, such as food, beverages, etc. The body 21 specifically includes a bottom wall, a pair of first side walls 21a disposed opposite to each other, and a pair of second side walls 21b disposed opposite to each other. The bottom wall is used to carry storage objects, and the pair of first side walls 21a and the pair of second side walls 21b extend vertically upward from the bottom wall respectively.

In order to clearly express the position and direction described in this embodiment, the direction defined by the relative position of the pair of first side walls 21a is defined as the front-to-back direction (also called the longitudinal direction), and the direction defined by the relative position of the pair of second side walls 21b is defined as the left-to-right direction (also called the transverse direction). That is, the pair of first side walls 21a are arranged relative to each other in the front and back directions, and the pair of second side walls 21b are arranged relative to each other in the left and right directions. In addition, the plane defined by the front-to-back direction and the left-to-right direction is defined as the horizontal plane, and the direction perpendicular to the horizontal plane is defined as the vertical direction.

A pair of guide mechanisms 22 are respectively arranged on a pair of second side walls 21b, that is, a guide mechanism 22 is arranged on each second side wall 21b. The guide mechanism 22 specifically includes a plate body 22a, a guide portion 22b, and a mounting hole 22c. The guide portion 22b and the plate body 22a form a U-shaped groove with an opening downward, and the guide mechanism 22 is hooked on the upper end surface of the second side wall 21b through the U-shaped groove, and the guide mechanism 22 can slide back and forth along the upper end surface of the second side wall 21b, so as to facilitate the removal or assembly of the guide mechanism 22 and the first partition frame 232 from the accommodating chamber 10. In addition, when the guide mechanism 22 is hooked on the upper end surface of the second side wall 21b, the relative movement of the guide mechanism 22 and the second side wall 21b in the left and right directions is restricted.

The first partition frame 232 is accommodated in the accommodating chamber 20 and can be used to divide the accommodating chamber 20 into front and back. Specifically, the first partition frame 232 includes a partition, which is horizontally placed in the accommodating chamber 20 to divide the accommodating chamber 20. The vertical surface where the partition is located defines the dividing surface of the first partition frame 232. The accommodating chamber 20 is divided into front and back with the dividing surface of the first partition frame 232 as the boundary. In this embodiment, the partition includes partition cross bars 232a and 232b arranged in the shape of long rods. The partition cross bars 232a and 232b extend left and right and are arranged at intervals in the vertical direction.

The first partition frame 232 is slidably connected to the main body 21 along the front-to-back direction via the guide mechanism 22. By sliding the first partition frame 232, the size and/or number of storage partitions formed by the front-to-back division of the accommodating cavity 20 can be adjusted to meet the diversified needs of storing different items.

Specifically, the first partition frame 232 includes a fixing portion 232d formed at both ends of the first partition frame 232, and the fixing portion 232d is matched to the mounting hole 22c of the guide mechanism 22, so that the first partition frame 232 is slidably disposed in the accommodating cavity 20 through the guide mechanism 22. That is, when the guide mechanism 22 slides forward and backward, the first partition frame 232 slides synchronously in the accommodating cavity 20.

The fixing portion 232d extends in the left-right direction and can be inserted into the mounting hole 22c in the left-right direction. When the fixing portion 232d is plugged into the mounting hole 22c and the guide mechanism 22 is hooked on the second side wall 21b, the guide mechanism 22 cannot move left-right relative to the body 21, and the fixing portion 232d and the mounting hole 22c are limited to each other in the left-right direction, so that the first partition frame 232 cannot move left-right relative to the guide mechanism 22, and the first partition frame 232 cannot move left-right relative to the body 21, thereby enhancing the stability of the first partition frame 232.

The second partition frame 231 is accommodated in the accommodating chamber 20 and can be used to divide the accommodating chamber 20 into left and right parts. In this embodiment, the second partition frame 231 is rotatably connected to the first partition frame 232 around the vertical axis t1 through the adjustment component 24. According to the positional relationship between the second partition frame 231 and the first partition frame 232, the storage device 200 has a stacked state (see FIG. 7 ) and an unfolded state. In this way, the number of storage partitions formed by dividing the accommodating chamber 20 can be adjusted as needed, thereby increasing the flexibility of dividing the accommodating chamber 20.

The second partition frame 231 includes a separator, which can be used to divide the accommodating cavity 20, and the vertical plane where the separator is located defines the dividing surface of the second partition frame 231. The lateral width of the accommodating cavity 20 (that is, the distance between a pair of second side walls 21b) is greater than the longitudinal width of the accommodating cavity 20 (that is, the distance between a pair of first side walls 21a), and accordingly, the width of the dividing surface of the first partition frame 232 is greater than the width of the dividing surface of the second partition frame 231, that is, the length of the partition is greater than the length of the separator.

In this embodiment, the separator includes partition longitudinal rods 231a and 231b which are arranged in the shape of long rods. The partition longitudinal rods 231a and 231b are parallel to each other and arranged at intervals in the vertical direction.

Referring to FIG. 7 , when the storage device 200 is in the stacked state, the partition surface of the second partition frame 231 is coplanar with the partition surface of the first partition frame 232, the partition longitudinal bars 231a, 231b and the partition cross bars 232a, 232b extend in the left-right direction and are located in the same vertical plane, and the partition cross bar 232a, the partition longitudinal bar 231a, the partition longitudinal bar 231b, and the partition cross bar 232b are arranged in sequence in the vertical direction; when the storage device 200 is in the unfolded state, the second partition frame 231 and the first partition frame 232 are arranged crosswise, and the accommodating cavity 20 can be arranged with the first partition frame 232. The partition frame 232 is divided into front and back with the partition surface as the boundary, and the accommodating cavity 20 can be divided into left and right with the partition surface of the second partition frame 231 as the boundary. At this time, the partition surface of the second partition frame 231 has a non-zero angle with the partition surface of the first partition frame 232. In the present embodiment, the partition surface of the second partition frame 231 is perpendicular to the partition surface of the first partition frame 232. Specifically, the partition longitudinal rods 231a and 231b extend in the front-to-back direction, and the partition transverse rods 232a and 232b extend in the left-to-right direction. The partition longitudinal rods 231a and 231b are perpendicular to the partition transverse rods 232a and 232b.

The second partition frame 231 further includes a pair of connecting rods 231c. The connecting rods 231c connect the ends of the partition longitudinal rods 231a and 231b, are coplanar with the partition longitudinal rods 231a and 231b, and together with the partition longitudinal rods 231a and 231b, form a rectangular frame.

Furthermore, the second partition frame 231 can also be slidably connected to the first partition frame 232 through the adjustment component 24, that is, the second partition frame 231 can both slide and rotate around the vertical axis t1 relative to the first partition frame 232 to adjust the number/size of storage partitions formed by dividing the accommodating cavity 20.

Among them, the above-mentioned second partition frame 231 is slidably connected to the first partition frame 232 through the adjustment component 24, and there are multiple implementation methods: first, the first partition frame 232 is non-slidably connected to the adjustment component 24, and the second partition frame 231 is slidably connected to the adjustment component 24, so that the size/number of storage partitions formed by the accommodating chamber 20 being divided front and back by the first partition frame 232 can be adjusted; second, the first partition frame 232 is slidably connected to the adjustment component 24, and the second partition frame 231 is non-slidably connected to the adjustment component 24, so that the size/number of storage partitions formed by the accommodating chamber 20 being divided left and right by the second partition frame 231 can be adjusted; third, as in the present embodiment, the first partition frame 232 is slidably connected to the adjustment component 24, and the second partition frame 231 is also slidably connected to the adjustment component 24, so that the size/number of storage partitions formed by the accommodating chamber 20 being divided front and back by the first partition frame 232 and the storage partitions formed by the second partition frame 231 can be adjusted, which is more flexible.

The specific structure of the adjustment component 24 in this embodiment is the same as the specific structure of the adjustment component 14 in Example 1 and will not be repeated here. The only difference lies in the matching relationship between the adjustment component 24 and the first partition frame 232 and the second partition frame 231. This difference will be described in detail below.

The adjustment component 24 is configured as a cylindrical structure that is mirror-symmetrical along a horizontal plane q'.

The adjustment assembly 24 includes a second adjustment mechanism matched with the first partition frame 232 and a first adjustment mechanism matched with the second partition frame 231. In this embodiment, the second adjustment mechanism is provided in two, namely, a second adjustment mechanism 241a matched with the partition crossbar 232a (its specific structure refers to the second adjustment mechanism 141a of Example 1) and a second adjustment mechanism 241b matched with the partition crossbar 232b (its specific structure refers to the second adjustment mechanism 141b of Example 1); the first adjustment mechanism is also provided in two, namely, a first adjustment mechanism 242a matched with the partition longitudinal rod 231a (its specific structure refers to the first adjustment mechanism 142a of Example 1) and a first adjustment mechanism 242b matched with the partition longitudinal rod 231b (its specific structure refers to the first adjustment mechanism 142b of Example 1); the first adjustment mechanism 242a matches the second adjustment mechanism 241a, and the first adjustment mechanism 242b matches the second adjustment mechanism 241b.

The first adjustment mechanism 242a includes a first channel 245a through which the partition longitudinal rod 231a passes. When the first adjustment mechanism 242a is assembled with the partition longitudinal rod 231a, the first adjustment mechanism 242a slides along the partition longitudinal rod 231a. Similarly, the first adjustment mechanism 242b includes a first channel 245b through which the partition longitudinal rod 231b passes. When the first adjustment mechanism 242b is assembled with the partition longitudinal rod 231b, the first adjustment mechanism 242b slides along the partition longitudinal rod 231b. The first channel 245a and the first channel 245b are parallel, and the adjustment assembly 24 is slidably coupled to the second partition frame 231.

The second adjustment mechanism 241a includes a second passage 244a through which the partition crossbar 232a passes. When the second adjustment mechanism 241a is assembled with the partition crossbar 232a, the second adjustment mechanism 241a slides along the partition crossbar 232a. Similarly, the second adjustment mechanism 241b includes a second passage 244b through which the partition crossbar 232b passes. When the second adjustment mechanism 241b is assembled with the partition crossbar 232b, the second adjustment mechanism 241b slides along the partition crossbar 232b. The second passage 244a and the second passage 244b are parallel, and the adjustment assembly 24 is slidably connected to the first partition frame 232.

Furthermore, the first adjustment mechanism 242a and the second adjustment mechanism 241a are matched and can rotate relative to each other around the vertical axis t1. In this embodiment, (with the body 21 as a reference) the first adjustment mechanism 242a rotates around the vertical axis t1. Similarly, the first adjustment mechanism 242b and the second adjustment mechanism 241b are matched and can rotate relative to each other around the vertical axis t1. In this embodiment, (with the body 21 as a reference) the first adjustment mechanism 242b rotates around the vertical axis t1.

Specifically, the adjustment assembly 24 further includes a cam structure, which is formed between the first adjustment mechanism and the second adjustment mechanism. In this embodiment, the number of the cam structures is set to two, namely, a cam structure 243a formed between the first adjustment mechanism 242a and the second adjustment mechanism 241a, and a cam structure 243b formed between the first adjustment mechanism 242b and the second adjustment mechanism 241b. Of course, in a modified embodiment, only one of the cam structure 243a and the cam structure 243b may be set.

Taking the cam structure 243a as an example, the specific structure of the cam structure is introduced (the specific structure of the cam structure 243b refers to the cam structure 243a and will not be repeated). The cam structure 243a includes a first concave-convex curved surface 431a' with a full-circle wavy shape formed on the upper end surface of the first adjustment mechanism 242a and a second concave-convex curved surface 423a' with a full-circle wavy shape formed on the lower end surface of the second adjustment mechanism 241a. The first concave-convex curved surface 431a' and the second concave-convex curved surface 423a' are adapted to each other; and when the first adjustment mechanism 242a and the second adjustment mechanism 241a rotate relative to each other around the vertical axis t1, the second concave-convex curved surface 423a' and the first concave-convex curved surface 431a' abut against each other, so that the first adjustment mechanism 242a and the second adjustment mechanism 241a perform a reciprocating jumping motion away from or close to each other in the vertical direction.

The cam structure 243a has at least two lowest point meshing positions (see Figures 9a and 9c) where the second concavoconvex curved surface 423a' and the first concavoconvex curved surface 431a' are concavoconvexly matched with each other, and a highest point abutting position (see Figure 9b) where the second concavoconvex curved surface 423a' and the first concavoconvex curved surface 431a' are convexly abutted with each other. When the cam structure 243a moves from the lowest point meshing position to the highest point abutting position, the first adjustment mechanism 242a and the second adjustment mechanism 241a move away from each other in the vertical direction; when the cam structure 243a moves from the highest point abutting position to the lowest point meshing position, the first adjustment mechanism 242a and the second adjustment mechanism 241a move closer to each other in the vertical direction.

When the second partition frame 231 rotates relative to the first partition frame 232 around the vertical axis t1, taking the process of the storage device 200 changing from the stacked state to the unfolded state as an example (the process of the storage device 200 changing from the unfolded state to the stacked state is the opposite, which will not be repeated):

Referring to FIG. 9a , when the storage device 200 is in the stacked state, the adjustment assembly 24 is in the first engagement state, at which the first channels 245a, 245b and the second channels 244a, 244b are parallel, and accordingly, the partition surface of the first partition frame 232 is parallel to the partition surface of the second partition frame 231, and the cam structures 243a, 243b are both in the lowest engagement position;

Referring to FIG. 9b , when the storage device 200 switches from the stacked state to the unfolded state, in the process of the adjustment component 24 changing from the first meshing state to the critical state, the cam structures 243a and 243b both move from the lowest meshing position to the highest abutting position, and the first adjustment mechanism 242a and the second adjustment mechanism 241a move away from each other in the vertical direction, and the first adjustment mechanism 242b and the second adjustment mechanism 241b move away from each other in the vertical direction; until the adjustment component 24 is in the critical state, the cam structures 243a and 243b are both in the highest abutting position; then, in the process of the adjustment component 24 changing from the critical state to the second meshing state, the first adjustment mechanism 242a and the second adjustment mechanism 241a move closer to each other in the vertical direction, and the first adjustment mechanism 242b and the second adjustment mechanism 241b move closer to each other in the vertical direction;

Referring to Figure 9c, when the storage device 200 is in the expanded state, the adjustment component 24 is in the second engaged state. At this time, the first channels 245a, 245b and the second channels 244a, 244b are perpendicular to each other. Correspondingly, the dividing surface of the first dividing frame 232 is perpendicular to the dividing surface of the second dividing frame 231, and the cam structures 243a, 243b are both in the other lowest engagement position.

Furthermore, the cam structures 243a and 243b are both configured as a circumferentially divided structure, that is, when the cam structures 243a and 243b are switched between two adjacent lowest meshing positions, the first adjustment mechanism 242a and the second adjustment mechanism 241a are relatively rotated 90° around the vertical axis t1, and the first adjustment mechanism 242b and the second adjustment mechanism 241b are relatively rotated 90° around the vertical axis t1. Furthermore, the second partition frame 231 is relatively rotated 90° around the vertical axis t1 relative to the first partition frame 232, so that the storage device 200 switches between the stacked state and the unfolded state, completing a flipping cycle.

Meanwhile, when the cam structures 243a and 243b change between the lowest meshing position and the highest contact position, the first adjustment mechanism 242a and the second adjustment mechanism 241a rotate 45° relative to each other around the vertical axis t1, and the first adjustment mechanism 242b and the second adjustment mechanism 241b rotate 45° relative to each other around the vertical axis t1.

Furthermore, when the cam structures 243a and 243b are not in the lowest engagement position, the adjustment component 24 is always subjected to an elastic driving force that drives the cam structures 243a and 243b to move to the lowest engagement position, that is, the elastic driving force drives the first adjustment mechanism 242a and the second adjustment mechanism 241a to have a tendency to approach each other in the vertical direction, and the first adjustment mechanism 242b and the second adjustment mechanism 241b to have a tendency to approach each other in the vertical direction.

In this embodiment, the elastic driving force is provided by the first partition frame 232. Specifically, the first partition frame 232 is set to a rigid material, and further includes a pair of connecting members 232c connecting the end of the partition cross bar 232a and the end of the partition cross bar 232b, and the connecting members 232c and the partition cross bars 232a and 232b together form a rectangular frame; the first adjustment mechanisms 242a and 242b are fixedly connected in the vertical direction. When the cam structures 243a and 243b are in the lowest meshing position, the first partition frame 232 has no elastic deformation, and its partition cross bars 232a and 232b are parallel to each other and have an initial spacing; when the cam structures 243a and 243b are not in the lowest meshing position (including being between the lowest meshing position and the highest abutment position and being in the highest abutment position), driven by the second adjustment mechanisms 241a and 241b, the local spacing of the partition cross bars 232a and 232b close to the adjustment component 24 is greater than the initial spacing and the ends maintain the initial spacing under the pulling of the connecting member 232c, so that the first partition frame 232 has elastic deformation, and the elastically deformed first partition frame 232 applies the elastic driving force on the adjustment component 24.

In this way, during a flipping cycle when the storage device 200 switches between the stacked state and the unfolded state: under the action of an artificial external force, the second partition frame 231 rotates relative to the first partition frame 232 around the vertical axis t1, the adjustment component 24 changes from the first meshing state to the critical state (or from the second meshing state to the critical state), the cam structures 243a and 243b both move from the lowest meshing position to the highest abutting position, and the second adjustment mechanisms 241a and 241b move away from each other in the vertical direction, driving the first partition frame 232 to undergo elastic deformation; when the adjustment member 244 is adjusted, the second adjustment member ... When the joint assembly 24 reaches the critical state, the cam structures 243a and 243b are both in the highest point abutment position, and the elastic deformation of the first partition frame 232 reaches the maximum; after passing the critical state, under the action of the elastic restoring force of the first partition frame 232, the second adjustment mechanisms 241a and 241b approach each other in the vertical direction, and the adjustment assembly 24 changes from the critical state to the second meshing state (or from the critical state to the first meshing state), thereby transforming the storage device 200 from the stacked state to the unfolded state (or from the unfolded state to the stacked state).

Of course, in a variation of the embodiment, the storage device 200 may further include an elastic member providing the elastic driving force, wherein the elastic member is disposed between the first adjusting mechanism and the second adjusting mechanism, and when the cam structure is not in the lowest engagement position, the elastic member undergoes elastic deformation.

Compared with the prior art, the storage device 200 of this embodiment can adjust the number/size of storage partitions formed by dividing the accommodating cavity 20 as needed; and the first partition frame 232 is easy to disassemble and assemble, and has good stability during use.

Example 3

10a to 14b , this embodiment provides a storage device 300 , which is specifically configured as a storage drawer, including a body 31 , a pair of guide mechanisms 32 , a first partition frame 332 , a second partition frame 331 and an adjustment assembly 34 .

The body 31 is surrounded by a substantially rectangular accommodating cavity 30 with an upper opening, and the accommodating cavity 30 is used to store various storage items, such as food, beverages, etc. The body 31 includes a bottom wall, a pair of first side walls 31a arranged opposite to each other, and a pair of second side walls 31b arranged opposite to each other. The bottom wall is used to carry storage items, and the pair of first side walls 31a and the pair of second side walls 31b extend vertically upward from the bottom wall respectively. Among them, a first side wall 31a also constitutes the box door of the storage compartment.

In order to clearly express the position and direction described in this embodiment, the direction defined by the relative position of the pair of first side walls 31a is defined as the front-to-back direction (also called the longitudinal direction), and the direction defined by the relative position of the pair of second side walls 31b is defined as the left-to-right direction (also called the transverse direction). That is, the pair of first side walls 31a are arranged relative to each other in the front and back directions, and the pair of second side walls 31b are arranged relative to each other in the left and right directions. In addition, the plane defined by the front-to-back direction and the left-to-right direction is defined as the horizontal plane, and the direction perpendicular to the horizontal plane is defined as the vertical direction.

A pair of guide mechanisms 32 are respectively arranged on a pair of second side walls 31b, that is, a guide mechanism 32 is arranged on each second side wall 31b. The guide mechanism 32 includes a guide rod 32a, a guide member 32b and a fixing seat 32c, wherein: the guide mechanism 32 is fixed to the body 31 through the fixing seat 32c, and the fixing method between the fixing seat 32c and the body 31 can be threaded connection, riveting, snap connection, etc.; the guide rod 32a is parallel to the second side wall 31b and extends in the front-to-back direction; the guide member 32b is sleeved on the guide rod 32a and can slide forward and backward along the guide rod 32a. In this embodiment, the guide rod 32a is arranged in a long strip with a square cross section, and the guide member 32b is adapted to the guide rod 32a so that the guide member 32b can only slide forward and backward along the guide rod 32a.

The first partition frame 332 is accommodated in the accommodating cavity 30 and can be used to divide the accommodating cavity 30 into front and back. Specifically, the first partition frame 332 includes a partitioning member, which is horizontally arranged (i.e., arranged to extend in the left-right direction) in the accommodating cavity 30 to divide the accommodating cavity 30, and the vertical plane where the partitioning member is located defines the dividing surface of the first partition frame 332, and the accommodating cavity 30 is divided into front and back with the dividing surface of the first partition frame 332 as the boundary. In this embodiment, the partitioning member includes partitioning cross bars 332a and 332b arranged in the shape of long rods, and the partitioning cross bars 332a and 332b extend left and right and are arranged at intervals in the vertical direction.

The first partition frame 332 further includes a pair of connecting members 332c. The connecting members 332c connect the ends of the partition crossbar 332a and the ends of the partition crossbar 332b, and together with the partition crossbars 332a and 332b, form a rectangular frame.

The first partition frame 332 is slidably connected to the main body 31 along the front-to-back direction through the guide mechanism 32. By sliding the first partition frame 332, the size and/or number of storage partitions formed by the front-to-back division of the accommodating cavity 30 can be adjusted to meet the diversified needs of storing different items.

Specifically, the first partition frame 332 includes a pair of fixing portions 332d formed at the left and right ends of the first partition frame 332, and each fixing portion 332d is connected to a corresponding guide member 32b. When the guide member 32b slides forward and backward along the guide rod 32a, the first partition frame 332 synchronously slides forward and backward in the accommodating chamber 30 to change the size and/or number of storage partitions on both sides of the first partition frame 332.

The extension direction of the fixing portion 332d is parallel to the extension direction of the partition cross bars 332a and 332b, that is, the fixing portion 332d extends in the left-right direction; the fixing portion 332d and the guide member 32b are respectively provided with corresponding screw holes, and the two can be fixedly connected by threads.

In this embodiment, each second side wall 31b includes a guide groove 31c extending forward and backward and a hollow assembly cavity, and the guide groove 31c connects the assembly cavity and the accommodating cavity 30. The guide mechanism 32 is arranged in the assembly cavity to increase the aesthetics. The left and right ends of the first partition frame 332 pass through the guide groove 31c and are connected to the guide mechanism 32. Specifically, the fixing portion 332d passes through the guide groove 31c from the accommodating cavity 30 and is connected to the guide member 32b.

The second partition frame 331 is accommodated in the accommodating chamber 30 and can be used to divide the accommodating chamber 30 into left and right parts. In this embodiment, the second partition frame 331 is rotatably connected to the first partition frame 332 around the vertical axis t2 through the adjustment component 34. According to the positional relationship between the second partition frame 331 and the first partition frame 332, the storage device 300 has a stacked state (see FIG. 10 b) and an unfolded state (see FIG. 10 a). By setting the second partition frame 331 to be rotatably connected to the first partition frame 332, the number of storage partitions formed by dividing the accommodating chamber 30 can be adjusted, thereby increasing the flexibility of dividing the accommodating chamber 30.

The second partition frame 331 includes a separator, which can be used to divide the accommodating cavity 30, and the vertical plane where the separator is located defines the dividing surface of the second partition frame 331. The lateral width of the accommodating cavity 30 (that is, the distance between a pair of second side walls 31b) is greater than the longitudinal width of the accommodating cavity 30 (that is, the distance between a pair of first side walls 31a), and accordingly, the width of the dividing surface of the first partition frame 332 is greater than the width of the dividing surface of the second partition frame 331, that is, the length of the partition is greater than the length of the separator.

In this embodiment, the separator includes partition longitudinal rods 331a and 331b which are arranged in the shape of long rods. The partition longitudinal rods 331a and 331b are parallel to each other and arranged at intervals in the vertical direction.

Referring to FIG. 10b, when the storage device 300 is in the stacked state, the partition surface of the second partition frame 331 is coplanar with the partition surface of the first partition frame 332, and the partition longitudinal rods 331a, 331b and the partition transverse rods 332a, 332b extend in the left-right direction and are located in the same vertical plane, so that the occupied space of the second partition frame 331 can be reduced when idle, while increasing the neatness and aesthetics; referring to FIG. 10a, when the storage device 300 is in the unfolded state, the second partition frame 331 and the first partition frame 332 are cross-arranged, and the accommodating cavity 30 can be divided into the first partition frame 331 and the first partition frame 332. The accommodating cavity 30 can be divided into front and back parts by the dividing surface of the second dividing frame 332, and the accommodating cavity 30 can be divided into left and right parts by the dividing surface of the second dividing frame 331. At this time, the dividing surface of the second dividing frame 331 and the dividing surface of the first dividing frame 332 have a non-zero angle. In the present embodiment, the dividing surface of the second dividing frame 331 is perpendicular to the dividing surface of the first dividing frame 332. Specifically, the dividing longitudinal rods 331a and 331b extend in the front-to-back direction, the dividing transverse rods 332a and 332b extend in the left-to-right direction, and the dividing longitudinal rods 331a and 331b are perpendicular to the dividing transverse rods 332a and 332b.

Furthermore, the partition may also include a glass partition (not shown), which is selectively assembled by the user between the partition crossbar 332a and the partition crossbar 332b. By providing the partition, the stored items in the storage partitions on the front and rear sides of the first partition shelf 332 do not touch each other, thereby avoiding odor contamination and preventing the stored items from sliding across and falling between the partition crossbar 332a and the partition crossbar 332b. Of course, the partition may not only be located between the partition crossbar 332a and the partition crossbar 332b, but may also partially extend upward to above the partition crossbar 332a, and/or partially extend downward to below the partition crossbar 332b.

Furthermore, in the vertical direction, the partition longitudinal rod 331a and the partition longitudinal rod 331b are arranged adjacent to each other, and the partition longitudinal rod 331a is always higher than the upper boundary of the partition (i.e., the partition transverse rod 332a in this embodiment), and the partition longitudinal rod 331b is always lower than the lower boundary of the partition (i.e., the partition transverse rod 332b in this embodiment). The partition longitudinal rod 331a, the partition transverse rod 332a, the partition, the partition transverse rod 332b, and the partition longitudinal rod 331b are arranged in sequence in the vertical direction. In this way, when the storage device 300 is in the stacked state, the second partition frame 331 will not interfere with the partition.

The second partition frame 331 also includes a pair of connecting rods 331c connecting the ends of the partition longitudinal rod 331a and the ends of the partition longitudinal rod 331b. The connecting rods 331c are arranged to be non-coplanar with the partition longitudinal rods 331a and 331b. When the storage device 300 is in the stacked state, the pair of connecting rods 331c are abutted against the partition cross bars 332a and 332b and are respectively located on the front and rear sides of the first partition frame 332.

Furthermore, the second partition frame 331 can also be slidably connected to the first partition frame 332 through the adjustment component 34, that is, the second partition frame 331 can both slide relative to the first partition frame 332 and rotate around the vertical axis t2. In this way, on the one hand, the number of storage partitions formed by dividing the accommodating cavity 30 can be adjusted, and on the other hand, the size of the storage partitions can be adjusted, thereby increasing the flexibility of dividing the accommodating cavity 30.

Among them, the above-mentioned second partition frame 331 is slidably connected to the first partition frame 332 through the adjustment component 34, and there are multiple implementation methods: first, the first partition frame 332 is non-slidably connected to the adjustment component 34, and the second partition frame 331 is slidably connected to the adjustment component 34, so that the size/number of storage partitions formed by the accommodating chamber 30 being divided front and back by the first partition frame 332 can be adjusted; second, the first partition frame 332 is slidably connected to the adjustment component 34, and the second partition frame 331 is non-slidably connected to the adjustment component 34, so that the size/number of storage partitions formed by the accommodating chamber 30 being divided left and right by the second partition frame 331 can be adjusted; third, as in the present embodiment, the first partition frame 332 is slidably connected to the adjustment component 34, and the second partition frame 331 is also slidably connected to the adjustment component 34, so that the size/number of storage partitions formed by the accommodating chamber 30 being divided front and back by the first partition frame 332 and the storage partitions formed by the accommodating chamber 30 being divided left and right by the second partition frame 331 can be adjusted, and the flexibility is higher.

In this embodiment, two adjusting components 34 are provided, one of which is matched with the separating longitudinal rod 331a and the separating transverse rod 332a, and the other is matched with the separating longitudinal rod 331b and the separating transverse rod 332b. Referring to FIGS. 11 to 14b, the structure of the adjusting component 34 is introduced by taking the matching with the separating longitudinal rod 331a and the separating transverse rod 332a as an example.

The adjustment assembly 34 includes a first adjustment mechanism 34b and a second adjustment mechanism 34a. The first adjustment mechanism 34b is coupled to one of the first partition frame 332 and the second partition frame 331, and the second adjustment mechanism 34a is coupled to the other of the first partition frame 332 and the second partition frame 331. In this embodiment, the first adjustment mechanism 34b is coupled to the first partition frame 332, and the second adjustment mechanism 34a is coupled to the second partition frame 331.

The first adjustment mechanism 34b includes a shaft member 430, a fixing member 440, a cushion member 450, and a first passage 342 formed between the cushion member 450 and the fixing member 440. The fixing member 440 includes a mounting hole 443, a positioning hole 441, and a groove 442. The cushion member 450 includes a positioning column 451 and a mounting hole 452. The mounting hole 443 and the mounting hole 452 correspond to each other and are threadedly connected with the screw 470 respectively. The positioning column 451 is inserted into the positioning hole 441 to facilitate the assembly and positioning of the fixing member 440 and the cushion member 450. The cushion member 450 and the fixing member 440 jointly form a first passage 342 located at the groove 442. The first passage 342 is slidably passed through by the partition crossbar 332a, so that the first adjustment mechanism 34b is slidably connected to the partition crossbar 332a (that is, the first adjustment mechanism 34b can slide left and right along the partition crossbar 332a), thereby making the adjustment assembly 34 slidably connected to the first partition frame 332.

The second adjustment mechanism 34a includes an end cap component 410, a sleeve component 420, and a second channel 341 formed between the end cap component 410 and the sleeve component 420. The end cap component 410 includes a hook 411 and a groove 412, and the sleeve component 420 includes a groove 421 and a groove 422 that match the hook 411; the end cap component 410 and the sleeve component 420 can be matched in the vertical direction and fixed by snapping through the hook 411 and the groove 421; the groove 412 and the groove 422 form the second channel 341. The second channel 341 is for the partitioning longitudinal rod 331a to pass through, so that the second adjustment mechanism 34a is slidably matched with the partitioning longitudinal rod 331a (that is, the second adjustment mechanism 34a can slide along the partitioning longitudinal rod 331a), thereby making the adjustment component 34 slidably connected to the second partition frame 331.

Preferably, the sleeve member 420 further includes a guiding slope 4210 to guide the hook 411 to be smoothly coupled to the slot 421 .

Further, the first adjustment mechanism 34 b is rotationally coupled to the second adjustment mechanism 34 a via a rotation shaft member 430 . Specifically, the shaft component 430 includes a component body 432, and the component body 432 includes a hanging platform portion 4321 and a matching portion 4322, the hanging platform portion 4321 and the matching portion 4322 are arranged in a step-like manner and are respectively cylindrical; accordingly, the sleeve component 420 has an installation channel 424 that matches the shaft component 430, the diameter of the hanging platform portion 4321 is larger than the diameter of the installation channel 424, and the diameter of the matching portion 4322 is equal to or slightly smaller than the diameter of the installation channel 424; during assembly, the shaft component 430 can be vertically downwardly matched with the sleeve component 420 from the upper side of the sleeve component 420 (that is, the side close to the end cover component 410), the matching portion 4322 is penetrated into the installation channel 424 and the hanging platform portion 4321 is limited by the sleeve component 420, so that the shaft component 430 is vertically downwardly assembled to the sleeve component 420 in an inseparable manner.

The shaft member 430 includes a mated surface 4320 formed on the outer surface of the mating portion 4322, and the sleeve member 420 includes a mating surface 4240 formed on the inner wall of the installation channel 424. The mating surface 4240 and the mated surface 4320 are adapted to each other so that the shaft member 430 is rotatably mated in the installation channel 424. In this embodiment, the shaft member 430 has a central axis, and the central axis defines a vertical axis t2.

One end of the matching portion 4322 of the rotating shaft component 430 is provided with a mounting hole, and the mounting hole matches with the screw 460 so that the rotating shaft component 430 is fixedly connected to the fixing component 440 .

Furthermore, when the first adjustment mechanism 34b and the second adjustment mechanism 34a rotate relative to each other, the partitioning horizontal rod 332a and the partitioning vertical rod 331a rotate relative to each other under the drive of the first adjustment mechanism 34b and the second adjustment mechanism 34a, and then the first partition frame 332 and the second partition frame 331 rotate relative to each other. In this embodiment, taking the body 31 as a reference, the second adjustment mechanism 34a rotates around the vertical axis t2 while the first adjustment mechanism 34b does not rotate.

Furthermore, the sleeve member 420 further includes at least two positioning grooves 423 recessed on the mating surface 4240 (i.e., the inner wall of the mounting channel 424). The mating portion 4322 of the member body 432 is provided with a horizontally extending mating hole; the shaft member 430 further includes an elastic telescopic member 431 connected to the member body 432, the elastic telescopic member 431 is arranged in the mating hole and at least a portion of the elastic telescopic member 431 protrudes out of the mating surface 4320 (i.e., the outer surface of the mating portion 4322) in a free state.

When the first adjusting mechanism 34b and the second adjusting mechanism 34a rotate relative to each other around the vertical axis t2: at the position between two adjacent positioning grooves 423, under the support of the matching surface 4240, the elastic telescopic member 431 is compressed and deformed and shrinks into the matching hole; at the position of the positioning groove 423, under the action of its own elastic restoring force, the elastic telescopic member 431 at least partially protrudes out of the matching surface 4320 and is clamped in the positioning groove 423, so as to realize the rotational positioning of the first adjusting mechanism 34b and the second adjusting mechanism 34a.

Specifically, the elastic telescopic member 431 includes an elastic portion 4311 inserted into the matching hole and a ball 4312 rollingly arranged at the end of the elastic portion 4311. When the first adjustment mechanism 34b and the second adjustment mechanism 34a rotate relative to each other around the vertical axis t2: at the position between two adjacent positioning grooves 423, under the abutment of the matching surface 4240, the elastic portion 4311 is compressed and deformed, and the ball 4312 shrinks into the matching hole and rolls along the matching surface 4240; at the position of the positioning groove 423, under the elastic restoring force of the elastic portion 4311 itself, the ball 4312 protrudes outward from the matching surface 4320 and is clamped in the positioning groove 423, so as to realize the rotation positioning of the first adjustment mechanism 34b and the second adjustment mechanism 34a.

In this embodiment, the positioning grooves 423 are set to 4 and divide the circle into four equal parts. In this way, when the first adjustment mechanism 34b and the second adjustment mechanism 34a rotate relative to each other around the vertical axis t2, the ball 4312 moves from one positioning groove 423 to another adjacent positioning groove 423, so that the storage device 300 can be switched between the stacked state and the unfolded state accordingly.

Specifically, when the second partition frame 331 rotates relative to the first partition frame 332 around the vertical axis t2, taking the process of the storage device 300 changing from the stacked state to the unfolded state as an example (the process of the storage device 300 changing from the unfolded state to the stacked state is the opposite, which will not be repeated):

Referring to FIG. 14a , when the storage device 300 is in the stacked state, the first channel 342 is parallel to the second channel 341 and both extend in the left-right direction (see the x direction in the figure), and accordingly, the partitioning cross bar 332a and the partitioning longitudinal bar 331a both extend in the left-right direction (see the x direction in the figure), and the partitioning surface of the first partition frame 332 is parallel to the partitioning surface of the second partition frame 331. At this time, the ball 4312 protrudes outward and fits into a positioning groove 423;

When the storage device 300 switches from the stacked state to the unfolded state, (with the body 31 as a reference) the second adjustment mechanism 34a drives the partition longitudinal rod 331a to rotate around the vertical axis t2, and the second partition frame 331 rotates relative to the first partition frame 332 around the vertical axis t2; under the abutment of the matching surface 4240, the elastic portion 4311 is compressed and deformed, and the ball 4312 shrinks into the matching hole and escapes from the positioning groove 423 where it was previously located, and then the ball 4312 rolls along the matching surface 4240;

Referring to Figure 14b, when the storage device 300 is in the expanded state, the first channel 342 is perpendicular to the second channel 341, the first channel 342 and the partition cross bar 332a still extend in the left-right direction (see the x direction in the figure), and the second channel 341 and the partition longitudinal bar 331a extend in the front-to-back direction (see the y direction in the figure), and the partition surface of the first partition frame 332 is perpendicular to the partition surface of the second partition frame 331. At this time, under the action of the elastic restoring force of the elastic part 4311 itself, the ball 4312 protrudes outward and is clamped in another positioning groove 423.

Furthermore, in this embodiment, the matching hole extends horizontally and penetrates the component body 432; two balls 4312 are provided, and are respectively rolled and arranged at the two ends of the elastic part 4311. When the first adjustment mechanism 34b and the second adjustment mechanism 34a rotate relative to each other around the vertical axis t2: under the abutment of the matching surface 4240, the elastic part 4311 is compressed and deformed, and the two balls 4312 are both contracted into the matching hole and roll along the matching surface 4240 synchronously; at the position of the positioning groove 423, under the elastic restoring force of the elastic part 4311 itself, the two balls 4312 are both protruded outward from the matching surface 4320 and are synchronously clamped in the corresponding positioning groove 423, thereby further reducing the rotation resistance.

Compared with the prior art, this embodiment has the following beneficial effects: by providing the movable cooperation between the first partition frame 332 and the second partition frame 331, the freedom and flexibility of the division of the accommodating chamber 30 are improved to adapt to different storage needs; the structure of the adjustment component 34 is sophisticated, and can be quickly assembled, and the first partition frame 332 and the second partition frame 331 can be disassembled/replaced in time to further enhance the flexibility of division; by selectively adding glass partitions, cross-slipping of items between different storage partitions can be avoided.

Although the present specification is described according to embodiments, not every embodiment contains only one independent technical solution. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
