As shown in FIG. 1 to FIG. 3 , a refrigerator may generally include a box body 10 , a door body 20 , a plurality of drawers 30 , 40 , 50 and at least one linkage mechanism 60 . The box body 10 defines a storage compartment 101 . A plurality of drawers 30 , 40 and 50 are arranged in the up-down direction in the storage compartment 101 . Each linkage mechanism 60 is installed between a group of two adjacent drawers, so that the two drawers can move forward synchronously. For example, in the embodiment shown in FIG. 2 and FIG. 3 , three drawers are arranged in the storage compartment 101 , which are the drawer 30 , the drawer 40 and the drawer 50 respectively from bottom to top. The drawer 30 and the drawer 40 constitute a group of two adjacent drawers, and a linkage mechanism 60 is arranged between them. The drawer 40 and the drawer 50 also constitute a group of two adjacent drawers, and a linkage mechanism 60 is arranged between them.

In the state shown in FIG. 3 , the drawer 30 is in a fully opened state, the upper drawer 40 is in the middle position, and the drawer 50 is also in the middle position. And at this time, the drawer 50 is further back than the drawer 40, so that a part of the upper side openings of the three drawers is exposed, and the opening degree of the drawers increases sequentially from top to bottom, similar to a stepped structure. The upper side drawer will not completely block the upper side opening of the adjacent lower side drawer, which is convenient for users to observe and access items.

As shown in FIG. 2 , the refrigerator may further include a door body 20 for opening and closing the storage compartment 101 . The door body 20 is fixed to the front end of the lowermost drawer 30, so as to drive the drawer 30 by pushing and pulling the door body 20, and then drive the drawer 40 and the drawer 50 to move forward.

Of course, in other embodiments, the door body for opening/closing the box body can also be provided by rotating, and the pivoting door body and the drawer are not connected.

As shown in FIG. 2 , among all the drawers, the drawer 30 located at the bottom is connected to the two lateral side walls of the storage compartment 101 through the two slide rail assemblies 11 (the lateral direction referred to herein refers to the left and right marked in the figure). direction). The slide rail assembly is commonly used in the prior art, and its specific structure will not be repeated here. In the remaining drawers, the front lower ends of the two lateral side walls of each drawer are respectively provided with front wheels so as to be able to roll on the top edges of the two lateral side walls of the lower drawer respectively, and the rear upper ends of each drawer are respectively provided with pulleys. , so that the drawer can be rolled on the correspondingly arranged slideways on the two lateral side walls of the storage compartment 101, thereby allowing the drawer to translate forward and backward. 2 and 3 , the drawer 40 has a front wheel 41 and a rear wheel 42 , the front wheel 41 rides on the top edge of the drawer 30 , and the rear wheel 42 is on the slideway 12 of the storage compartment 101 .

A schematic diagram of the state when the block 65 returns to the original position and the push block 61 rotates to pass over the moving block 65 .

The following describes the linkage mechanism 60 of an embodiment of the present invention with reference to FIGS. 2 to 9 , and takes the linkage mechanism 60 between the drawer 30 and the drawer 40 as an example for introduction.

The linkage mechanism 60 includes a push block 61 , a moving block 65 , a compression spring 68 and a convex portion 69 . The push block 61 is installed on the top of the lower drawer 30 . The moving block 65 is provided on the lateral side wall of the upper drawer 40 so as to be movable along the lateral direction of the refrigerator. The raised portion 69 is located on the lateral side wall of the storage compartment 101 . The compression spring 68 is configured to, when compressed by the moving stop 65 , apply a spring force to the moving stop 65 , which urges it away from the lateral side walls of the drawer 40 .

Of course, an elastic tongue can also be provided on the inner wall of the first box body 66 to replace the compression spring 68 . However, after the drawer is pulled for many times, the elastic tongue is prone to fatigue damage, and the deformable amount cannot reach the designed value, so that its elastic force is insufficient and cannot support the moving block 65 to move to its proper position. Moreover, the process of processing the elastic tongue on the inner wall of the first box body 66 is relatively complicated.

The compression spring 68, on the other hand, is low cost, readily available, and has a longer life. During normal use of the refrigerator, the compression springs can be accidentally damaged at all, which makes the reliability of the whole mechanism guaranteed.

The linkage mechanism 60 is configured to make the push block 61 abut against the rear side of the moving block 65 when the two adjacent drawers 30 and 40 are in the closed state (as shown in FIGS. 2 and 8 ). In this way, when the lower drawer 30 moves forward, the push block 61 pushes the moving block 65, thereby driving the upper drawer 40 to move forward. When the upper drawer 40 is pushed to the middle position (as shown in FIG. 3 ), the moving block 65 is squeezed by the protrusion 69 to overcome the elastic force of the compression spring 68 and move laterally from the original position to the direction close to the drawer 40 (moving to the left from the state shown in FIG. 8 ) and disengaging the push block 61 , thereby releasing the linkage between the two adjacent drawers 30 and 40 (as shown in FIG. 9 ).

The linkage mechanism 60 may also be configured to cause the moving block 65 to pass over the protrusion 69 to allow the drawer 40 to continue to move forward when the upper drawer 40 in the intermediate state is subjected to a forward force. After the moving block 65 passes over the protruding portion 69 , it returns to its original position under the elastic force of the compression spring 68 . This allows the upper drawer 40 to continue to be pulled forward in order to fully open it for easy access to items by the user.

In addition, the linkage mechanism 60 is also configured to push the lower drawer 30 backward when the push block 61 is in front of the moving block 65, so that the push block 61 contacts the moving block 65 to overcome an elastic torque to rotate forward, Therefore, the height of its top is lowered to pass over the moving block 65, so as to return to the rear side of the moving block 65 (as shown in Fig. 10), and then return to the original position under the action of the aforementioned elastic torque. In addition, when the push block 61 is located in front of the moving block 65 , the upper drawer 40 can be pulled forward, and the push block 61 can also be made to pass over the moving block 65 .

5 and 6 illustrate an alternative structure of the moving block 65 and the raised portion 69 . As shown in FIG. 5 and FIG. 6 , the linkage mechanism 60 further includes a first box body 66 for installing the moving block 65 . The first box body 66 is installed on the lateral side wall of the upper drawer 40, and at least one mounting rod 662 (two as shown in FIG. 6) extends laterally outward (to the right) from the wall surface that fits with the drawer 40, The compression spring 68 is sheathed on the mounting rod 662 , one end of which is abutted against the inner wall of the first box body 66 and one end is abutted against the moving block 65 , so as to generate elastic force when compressed by the moving block 65 . The moving block 65 is provided with a mounting hole 653 so as to be telescopically sleeved on the mounting rod 662 in the lateral direction. The bottom wall of the first box body 66 is provided with an escape groove 665 to allow the bottom 651 of the moving block 65 to protrude out of the first case body 66 through the escape groove 665 .

The side of the moving block 65 has at least one arc-shaped protrusion 652 whose axis is vertically arranged. The number of the arc-shaped protruding parts 652 can be two, which are respectively disposed above and below the mounting holes 653 . The right side of the first box body 66 is open, and the first box body 66 includes a cover body 67 for covering the opening thereof. The cover body 67 is provided with a plurality of holes 671 so as to be fixed on the column body 664 of the first box body 66 by screws 672 (threaded holes are provided). The cover body 67 is provided with an escape opening 673 to allow the arc-shaped protruding portion 6522 to protrude so as to be in contact with the protruding portion 69 and be pressed by the protruding portion 69 . The contact between the arc-shaped protruding portion 652 and the protruding portion 69 can not only realize the lateral retraction of the moving block 65 , but also because its surface is an arc-shaped surface, it is convenient to cross the protruding portion 69 with less effort.

The moving block 65 can be made of a plastic with high stiffness, high hardness and high wear resistance (eg POM), so as to make the surface of the arc-shaped protrusion 652 smoother, so as to facilitate it to pass the protrusion 69 . In addition, the surface of the arc-shaped protruding portion 652 is made more wear-resistant, so as to prevent it from being seriously worn by the protruding portion 69 and affecting normal use.

As shown in FIG. 5 , the protruding portion 69 can be an independently fabricated part, which is installed on the inner wall of the storage compartment 101 . The front and rear surfaces 691 and 693 of the raised portion 69 are inclined surfaces gradually inclined toward each other from the inner wall of the storage compartment 101 outward (to the left). This facilitates the movement of the stopper 65 over the raised portion 69 .

FIG. 7 illustrates an alternative structure of the push block 61 . Each linkage mechanism 60 also includes a second box body 63 for installing the push block 61 . The second box body 63 is mounted on the top of the lower drawer 30 and has mounting posts 631 extending in the lateral direction. The push block 61 has a mounting hole 611 to be mounted on the mounting post 631 . A curved elastic sheet 618 extends from the front surface of the push block 61 , and the curved elastic sheet 618 abuts against the inner front wall 639 of the second box body 63 to generate elastic deformation under pressure, thereby applying the aforementioned elasticity to the push block 61 torque. The bending elastic piece 618 can be a curved shape with an axis extending in the lateral direction of the drawer, and the height of its abutment point with the front surface of the push block 61 is higher than the height of the rotation axis of the push block 61, so that the push block 61 can be applied backward Rotational elastic torque. The bending elastic sheet 618 can be integrally formed with the push block 61, and can be made of POM material to improve its rigidity, strength and wear resistance, and save costs. The right side of the second box body 63 is open, and is covered with a box cover 64 . The box cover 64 is provided with a hole 641 so that the screw 642 can pass through and cooperate with the threaded hole 633 opened on the second box body 63 to fix the box cover 64 . The push block 61 protrudes out of the box body 63 through the opening 635 opened at the top of the second box body 63 .

A limiting groove 6312 is defined on the peripheral surface of the mounting post 631 , and the hole wall of the mounting hole 611 has a radially protruding positioning protrusion 612 , and the positioning protrusion 612 is located in the limiting groove 6312 . When the push block 61 rotates, the positioning protrusion 612 can only move within the range of the limiting groove 6312 , thereby limiting the rotation range of the push block 61 . Specifically, when the two adjacent drawers 30 and 40 are in the closed state, as shown in FIG. 9 , the positioning protrusion 612 is pressed against the rear wall of the limiting groove 6312 , so that the push block 61 cannot be rotated backward, so that it can Push the moving block 65 forward. When the push block 61 is in front of the moving block 65 and pushes the lower drawer 30 backward, the push block 61 is allowed to rotate backwards, at most until the positioning protrusion 612 abuts against the front wall of the limiting groove 6312, That is, the rotation is stopped. At this time, the push block 61 is enough to pass over the moving block 65, so as to return to the rear side of the moving block 65 (as shown in FIG. 10), and then return to the original position under the action of elastic torque. As shown in FIG. 8 , in the state of no external force, the front surface 613 of the push block 61 is a vertical plane so as to push the moving block 65 forward, and the rear surface 614 of the push block 61 is gradually inclined forward from bottom to top. so that when it contacts with the moving stopper 65 , it goes over the moving stopper 65 .

The linkage mechanism of the refrigerator of the present invention is simple in structure, but has a very practical function. And the number of parts is small, the possibility of failure is small, and the reliability is high.

In some embodiments, in each group of two adjacent linkage mechanisms 60, the protruding portion 69 of the linkage mechanism 60 on the lower side can be located closer to the position of the protruding portion 69 of the linkage mechanism 60 on the upper side forward. In this way, after a plurality of drawers are opened, the opening degree of the drawers from top to bottom increases sequentially, similar to a stepped structure. The upper side drawer will not completely block the upper side opening of the adjacent lower side drawer, which is convenient for users to observe and access items.

As shown in Figures 1-10, only one linkage mechanism 60 is provided between every two adjacent drawers. Of course, two left-right symmetrical linkage mechanisms 60 can also be arranged between every two adjacent drawers, so that both ends of the upper drawer are pushed and moved forward more smoothly.

By now, those skilled in the art will recognize that, although various exemplary embodiments of the present invention have been illustrated and described in detail herein, the present invention may still be implemented in accordance with the present disclosure without departing from the spirit and scope of the present invention. The content directly determines or derives many other variations or modifications consistent with the principles of the invention. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
