Detailed ways

The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

In each drawing of the present invention, for convenience of illustration, some dimensions of structures or parts are exaggerated relative to other structures or parts, and therefore, are only used to illustrate the basic structure of the subject matter of the present invention.

Referring to FIG. 1 , it is a schematic diagram of a refrigeration device 100 according to an embodiment of the present invention.

The refrigeration device 100 includes a box body 10 , a door body 20 and a hinge assembly 30 connecting the box body 10 and the door body 20 .

It should be noted that the refrigerating device 100 may be a refrigerator, a freezer, a wine cabinet, etc. Here, the refrigerating device 100 is a refrigerator as an example.

In addition, the hinge assembly 30 is not only applicable to the refrigeration device 100, but also applicable to other scenarios, such as cabinets, wardrobes, etc. The present invention uses the hinge assembly 30 applied to the refrigerator 100 as an example for illustration, but not limited thereto.

2 to 4 are schematic diagrams of the hinge assembly 30 according to the first embodiment of the present invention.

The hinge assembly 30 includes a first hinge part 31 connected to the box body 10 , a second hinge part 32 connected to the door body 20 , and a sliding piece 40 connected to the first hinge part 31 and the second hinge part 32 .

Here, "the first hinge 31 connected to the box 10" means that the first hinge 31 is connected to the box 10, and the first hinge 31 can be an independent part installed on the box 10, or can be directly integrally formed on the box. Parts on the body 10.

Similarly, "the second hinge part 32 connected to the door body 20" means that the second hinge part 32 is connected to the door body 20, and the second hinge part 32 can be an independent part installed on the door body 20, or can be integrally formed directly on the door body 20. Parts on the door body 20.

The hinge assembly 30 also includes a locking assembly 50 .

When the hinge assembly 30 is in the closed state, the locking assembly 50 locks the slide piece 40 and the second hinge piece 32 , that is, the slide piece 40 and the second hinge piece 32 are relatively stationary.

When the hinge assembly 30 is in the opening process, the second hinge member 32 and the sliding piece 40 rotate in situ relative to the first hinge member 31, and then the locking assembly 50 locks the first hinge member 31 and the sliding piece 40 and unlocks the second hinge member 31. The hinge part 32 , the second hinge part 32 rotates in situ relative to the sliding piece 40 .

It should be noted that "the hinge assembly 30 is in the opening process" means that the second hinge member 32 is opened in a direction away from the first hinge member 31, that is, the second hinge member 32 acts in one direction to drive the second hinge member 32 to move away from the first hinge member 31. The direction movement of the first hinge member 31 , when the hinge assembly 30 is installed on the refrigerator 100 , the opening process of the hinge assembly 30 corresponds to the opening process of the door body 20 .

In this embodiment, the locking and unlocking between the first hinge 31 , the second hinge 32 and the sliding plate 40 can be controlled by the locking assembly 50 , specifically, the second hinge is controlled by the locking assembly 50 first. 32 and the sliding piece 40 are mutually locked, and then the second hinge 32 and the sliding piece 40 are controlled to rotate in situ relative to the first hinge 31 together, and then the locking assembly 50 is used to control the connection between the second hinge 32 and the sliding piece 40 and the first hinge member 31 and the sliding piece 40 are mutually locked, thereby controlling the second hinge member 32 to rotate relative to the sliding piece 40 in situ.

It can be seen that the locking assembly 50 in this embodiment can effectively control the sequence of the two in-situ rotations. During the two in-situ rotations, there is a change in the position of the rotation axis, which can effectively control the movement track of the door body, thereby improving the refrigerator. 100 degrees of freedom in the opening and closing process of the door body 20, especially in the field of built-in refrigerators, the mutual interference between the door body 20 and the surrounding cabinets or walls during the opening and closing process can be avoided by switching the rotation axis.

It can be understood that the locking assembly 50 can be a mechanical structure or an electric control structure to control the sequence of the two in-situ rotations.

In this embodiment, the first hinge 31 and the slide 40 are connected through the first shaft 311 and the first connection hole 401 , and the second hinge 32 and the slide 40 are connected through the second shaft 402 and the first connection hole 401 . The two connecting holes 321 are connected. When the hinge assembly 30 is in the process of opening, the first shaft body 311 rotates in the first connecting hole 401 to drive the second hinge member 32 to rotate in situ relative to the first hinge member 31 together with the sliding piece 40 , and then the second shaft body 402 rotates in the second connecting hole 321 to drive the second hinge member 32 to rotate relative to the sliding piece 40 in situ.

That is to say, the first in-situ rotation of the hinge assembly 30 uses the first shaft 311 as the rotation axis, and the second in-situ rotation of the hinge assembly 30 uses the second shaft 402 as the rotation axis.

In order to further illustrate the movement track of the hinge assembly 30 , a simple schematic diagram of the hinge assembly 30 assembled to the refrigerator 100 and the refrigerator 100 embedded in the cabinet 200 is taken as an example for illustration with reference to FIG. 5 .

The box body 10 includes an opening 102 and a front end surface 103 arranged around the opening 102. The box body 10 also includes an accommodating chamber D and an outer side surface 13 adjacent to the hinge assembly 30 and on the extension of the rotation path of the door body 20. The door body 20 includes a The front wall 21 of the accommodating chamber D and the side wall 22 always sandwiched between the front wall 21 and the accommodating chamber D, a side edge 23 is formed between the front wall 21 and the side wall 22 .

The hinge assembly 30 is configured such that: when the first shaft body 311 rotates in the first connecting hole 401, there is a first distance between the first shaft body 311 and the front end surface 103 of the box body 10; When rotating in the second connecting hole 321 , there is a second distance between the second shaft body 402 and the front end surface 103 of the box body 10 , and the second distance is greater than the first distance.

In addition, when the first shaft body 311 rotates in the first connecting hole 401 , there is a third distance between the first shaft body 311 and the outer surface 13 of the box body 10 , and when the second shaft body 402 rotates in the second connecting hole 321 When rotating inwardly, there is a fourth distance between the second shaft body 402 and the outer surface 13 of the box body 10 , and the fourth distance is smaller than the third distance.

It should be noted that the above-mentioned distance refers to the distance between the first shaft body 311 and the second shaft body 402 at the position and the front end surface 103 and the outer surface 13 of the box body 10 when the hinge assembly 30 moves to a certain position. , not the distance in the closed state.

The specific instructions are as follows:

In actual operation, in order to improve the embedding effect, it is preferable to completely embed the refrigerator 100 into the cabinet 200. The refrigerator 100 is a free embedded refrigerator, that is, the front end 201 of the cabinet 200 and the front wall 21 of the door 20 are away from the side of the cabinet 10. Located on the same plane, or the front wall 21 of the door body 20 does not protrude from the front end 201 of the cabinet 200 at all.

In the prior art, all refrigerators are single-axis refrigerators, and a certain distance needs to be kept between the rotation axis of the refrigerator and the side wall and front wall of the refrigerator, so that there is enough space for foaming or other processes, that is, the existing The position of the rotation axis of the refrigerator is roughly located at the position of the first axis body 311 in FIG. 203 is set corresponding to the side edge 23 of the door body 20. When the door body 20 is opened, the side edge 23 will interfere with the door body 20 to limit the maximum opening angle of the door body 20. In order to ensure the normal opening of the door body 20, the prior art A common practice is to increase the distance between the inner wall 202 of the cabinet 200 and the refrigerator 100, which needs to be about 10 cm, which will seriously affect the embedding effect and is not conducive to the rational use of limited space.

In conjunction with FIG. 5 , the shaded area represents the door body 20 in the closed state. When the door body 20 is in the process of opening, if the door body 20 always rotates with the first shaft body 311 as the rotation axis (that is, the prior art), refer to FIG. 5 The dotted line door body 20' in the figure, because the first shaft body 311 is close to the front end surface 103, that is, the first shaft body 311 is far away from the front end 201 of the cabinet 200 at this time, when the door body 20' is opened to a certain angle, the corners 203 of the cabinet 200 It will interfere with the door body 20' to limit the maximum opening angle of the door body 20'.

In this embodiment, the door body 20 first rotates in situ with the first shaft body 311 as the rotation axis. Specifically, the second hinge member 32 and the sliding piece 40 rotate at a certain angle relative to the first hinge member 31 in situ. The position of the second hinge 32 and the sliding piece 40 changes, and the relative position of the second shaft 402 to the box body 10 also changes, and the second shaft 402 gradually moves away from the front end face 103, that is, the second shaft 402 gradually approaches The direction of the front end 201 of the cabinet 200 moves. At this time, the door body 20 rotates in situ with the second shaft body 402 at the current position as the rotation axis. Because the second shaft body 402 is farther away from the first shaft body 311 The front end surface 103 of the box body 10, referring to the solid line door body 20 in Figure 5, the interference effect of the corners 203 of the cabinet 200 on the door body 20 is greatly reduced, and the corners 203 of the cabinet 200 will interfere with each other when the door body 20 is opened to a relatively large angle , thereby greatly improving the maximum opening angle of the door body 20 .

That is to say, in this embodiment, the door body 20 is opened to a certain angle and then switched to rotate with the second shaft body 402 as the rotation axis. On the premise of ensuring that the refrigerator 100 is freely embedded in the cabinet 200, the maximum opening angle of the door body 20 can be effectively increased. , thereby facilitating the user to operate the refrigerator 100, which can greatly improve user experience.

Moreover, in this embodiment, there is no need to increase the distance between the inner wall 202 of the cabinet 200 and the refrigerator 100, and the seamless connection between the refrigerator 100 and the cabinet 200 can be achieved, which greatly improves the embedding effect.

In addition, while the second shaft body 402 in this embodiment gradually moves toward the front end 201 of the cabinet 200, it also gradually moves closer to the inner wall 202 of the cabinet 200, that is to say, when the door body 20 takes the second shaft body 402 as When the rotating shaft rotates, the second shaft body 402 is closer to the front end 201 and the inner wall 202 of the cabinet 200 than the first shaft body 311 at this time. In this way, the maximum opening angle of the door body 20 can be increased, and the door body can be opened more easily. The body 20 is away from the box body 10 to increase the opening of the box body 10, which facilitates the opening and closing of shelves, drawers, etc. in the box body 10, or in other words, can facilitate the picking and placing of articles.

Certainly, the second shaft body 402 finally serving as the rotation shaft can also be located at other positions. The shaft body 311 is close to the front end 201 of the cabinet 200 , and the second shaft body 402 is farther away from the inner wall 202 of the cabinet 200 than the first shaft body 311 .

It can be understood that the slide 40 controls the switching sequence of the first hinge 31 and the second hinge 32 during the opening and closing of the door 20 , which can effectively prevent the door 20 from interfering with the cabinet 200 during opening and closing.

In this embodiment, the shaft hole can include various distribution forms, specifically including:

The first shaft 311 is located on one of the first hinge 31 and the slide 40 , and the first connecting hole 401 is located on the other of the first hinge 31 and the slide 40 .

The second shaft 402 is located on one of the second hinge 32 and the slide 40 , and the second connecting hole 321 is located on the other of the second hinge 32 and the slide 40 .

In this embodiment, the first shaft body 311 is located on the first hinge member 31 , the first connecting hole 401 and the second shaft body 402 are located on the sliding plate 40 , and the second connecting hole 321 is located on the second hinge member 32 as an example.

It can be understood that, in other embodiments, the position of the shaft groove can be freely selected according to actual needs, and is not limited to the position of the shaft groove in this embodiment.

For the specific design of the hinge assembly 30 in this embodiment, reference may be made to the following examples. It should be understood that the following are only illustrative examples, and in other embodiments, the hinge assembly 30 may also have other structures.

In this embodiment, referring to FIG. 6 to FIG. 12 , the locking assembly 50 includes a rib 51 , a sliding groove 52 and a limiting member 53 , and the rib 51 and the sliding groove 52 are passed between the second hinge member 32 and the sliding piece 40 Cooperating with each other, the limiting part 53 is connected to the first hinge part 31 , and the locking assembly 50 further includes a first limiting part 54 located on the first hinge part 31 and a second limiting part 55 located on the sliding piece 40 .

That is to say, the first hinge member 31 is provided with a first limiting portion 54 and a limiting member 53 , the sliding piece 40 is provided with a second limiting portion 55 , and the rib 51 passes between the second hinge member 32 and the sliding piece 40 . And the chute 52 cooperates with each other.

When the hinge assembly 30 is in the closed state (refer to FIG. 13 to FIG. 17 ), the limiting member 53 restricts the rib 51 from sliding in the sliding groove 52 , and the second hinge member 32 and the sliding piece 40 are relatively stationary.

Here, the second hinge member 32 and the sliding piece 40 cooperate with each other through the rib 51 and the sliding groove 52, that is to say, the cooperation between the rib 51 and the sliding groove 52 realizes the connection between the second hinge member 32 and the sliding piece 40.
