Depending on the context, the term "if" as used herein may be interpreted as "when," "when," or "in response to determining."

[0039] Next, the embodiments of this specification are described in detail.

[0040] like Figure 1 and Figure 2 As shown, the drawer auxiliary movement device of the present application includes a drawer 1, a storage liner 2 and an auxiliary drive mechanism 3. The drawer 1 is movably arranged in the storage liner 2, and the auxiliary drive mechanism 3 is connected to the drawer 1 and the storage liner 2 respectively, so that the drawer 1 can be easily moved in the storage liner 2.

[0041] In one embodiment, the drawer 1 includes a first assembly position and a second assembly position. When the drawer 1 is in the second assembly position, it moves downward relative to the first assembly position. Specifically, when the drawer 1 is in the first assembly position, it indicates that the drawer 1 is completely contained within the storage liner 2; when the drawer 1 is in the second assembly position, it indicates that the drawer 1 is partially removed from the storage liner 2. This arrangement causes the drawer 1 to move downward relative to the storage liner 2 when it is pulled out, preventing the drawer 1 from being blocked by the crossbeam when being pulled out or pushed into the storage liner 2. This improves the convenience of using the drawer 1 and further enhances the user experience.

[0042] Further integration Figure 3 and Figure 4As shown, the drawer 1 is provided with a locking portion 11 and a supporting portion 12. The locking portion 11 and the supporting portion 12 are spaced apart. The locking portion 11 includes a second bead card groove 111, a bead contact rod 112, a bead card plate 113 and a push plate 114. The bead card plate 113 is provided on the side wall of the drawer 1, and the second bead card groove 111 is provided on the bead card plate 113. In the depth direction of the drawer 1, the depth of the second bead card groove 111 increases from top to bottom. Specifically, in the depth direction of the drawer 1, the bottom wall of the second bead card groove 111 has a certain slope. The push plate 114 is connected between the bead card plate 113 and the bead contact rod 112, and the bead contact rod 112 and the bead card plate 113 are spaced apart.

[0043] The support portion 12 protrudes from the side wall of the drawer 1 and is integrally provided on the side wall of the drawer 1. To facilitate easier movement of the drawer 1 between the first and second assembly positions, the support portion 12 is pivotally arranged relative to the side wall of the drawer 1. The support portion 12 is preferably cylindrical.

[0044] Further integration Figures 5 to 8 As shown, in one embodiment, the auxiliary drive mechanism 3 includes a reset assembly 31, a drive assembly 32, a first fixing member 33, a second fixing member 34, and a third fixing member 35. The reset assembly 31 is connected to the storage container 2, and the drive assembly 32 is connected to the drawer 1. The reset assembly 31 and the drive assembly 32 cooperate with each other and move synchronously. The first fixing member 33, the second fixing member 34, and the third fixing member 35 are all fixed to the side wall of the storage container 2.

[0045] In one embodiment, the reset assembly 31 includes an elastic member 311, a reset plate 312, and a limiting bead 313. The elastic member 311 is connected to the reset plate 312 and provides an elastic force for the reset plate 312 to reset. Specifically, the elastic member 311 applies an elastic force to the reset plate 312 at least when the drawer 1 is in the second assembly position. That is, the elastic member 311 may not deform before the drawer 1 is in the second assembly position, but must deform when the drawer 1 is in the second assembly position to obtain an elastic force, thereby assisting the drawer 1 when it moves to the first assembly position, making it easier for the drawer 1 to be pushed into the storage liner 2.

[0046] Preferably, the elastic member 311 constantly applies an elastic force to the return plate 312 during the transition between the first and second assembly positions of the drawer 1. Specifically, when the drawer 1 is pulled out to accommodate the inner container 2, the elastic member 311 applies a resistive elastic force to the drawer 1, preventing damage caused by excessive withdrawal. When the drawer 1 is pushed into the inner container 2, the elastic member 311 applies a return force to the drawer 1, facilitating its insertion.

[0047] The ends of the elastic member 311 are respectively connected to the first fixing member 33 and the reset plate 312. During the movement of the drawer 1, the elastic member 311 is stretched or compressed. Specifically, during the movement of the drawer 1, the elastic member 311 is always stretched, so that the elastic member 311 always has the tensile force to drive the drawer 1 to return to the first assembly position. Alternatively, during the movement of the drawer 1, the elastic member 311 is always compressed, so that the elastic member 311 always has the compressive force to drive the drawer 1 to return to the first assembly position. The elastic member 311 can be a spring, a reed, etc.

[0048] In one embodiment, a reset plate 312 is connected to the drive assembly 32. The reset plate 312 is preferably a rack. The reset plate 312 includes a mounting hole 3121. The reset plate 312 is positioned between the inner wall of the drawer 1 and the ball contact rod 112. Specifically, the reset plate 312 can be positioned within the retaining portion 11, between the ball contact rod 112 and the retaining plate 113.

[0049] The retaining bead 313 is disposed within the mounting hole 3121. Specifically, the thickness of the retaining bead 313 is greater than the thickness of the reset plate 312, and a portion of the retaining bead 313 is always located within the mounting hole 3121. The retaining bead 313 can move left and right within the mounting hole 3121 along the drawer 1, thereby securing the reset plate 312 to the storage liner 2 or the drawer 1.

[0050] When the drawer 1 is in the first assembly position, the limiting beads 313 are located in the mounting holes 3121 and are engaged with the engaging portion 11, while the reset plate 312 is fixed relative to the drawer 1. When the drawer 1 is in the second assembly position, the limiting beads 313 are located in the mounting holes 3121 and are engaged with the second fixing member 34, while the reset plate 312 is fixed relative to the second fixing member 34.

[0051] Furthermore, in the process of the drawer 1 moving from the first assembly position to the second assembly position, since the second bead groove 111 has a certain slope, the locking portion 11 moves downward with the drawer 1, and the bottom wall of the second bead groove 111 gradually squeezes the limiting bead 313 and moves along the left and right directions of the drawer 1, so that the limiting bead 313 located in the second bead groove 111 moves into the second fixing member 34, and then the reset plate 312 is fixed to the second fixing member 34, thereby releasing the drawer 1, making it convenient for the drawer 1 to pull out the storage liner 2.

[0052] Further integration Figure 9As shown, the second fixing member 34 includes a first bead retaining groove 341 and a relief groove 342. The depth of the first bead retaining groove 341 is less than that of the relief groove 342. When the drawer 1 is in the second assembly position, the retaining bead 313 is located in the first bead retaining groove 341, and the gap between the retaining bead 313 and the bottom wall of the relief groove 342 is greater than the thickness of the bead contact rod 112. The relief groove 342 extends through the second fixing member 34, and the second fixing member 34 is in contact with the reset plate 312.

[0053] During the movement of the drawer 1 from the second assembly position to the first assembly position, the ball contact rod 112 squeezes the limiting bead 313 and moves in the left-right direction of the drawer 1. Specifically, the ball contact rod 112 moves along with the drawer 1 in the avoidance groove 342 to contact the limiting bead 313, thereby pushing the limiting bead 313 out of the first bead groove 341 and then engaging it into the second bead groove 111.

[0054] In one embodiment, the drive assembly 32 assists the drawer 1 in switching between the first assembly position and the second assembly position. This arrangement makes the drawer 1 more labor-saving and convenient to move, improving the user's experience.

[0055] Further integration Figure 10 and Figure 11 As shown, the drive assembly 32 is connected to the support portion 12 and can rotate relative to the support portion 12. Specifically, the drive assembly 32 is detachably arranged relative to the support portion 12. In another embodiment, the drive assembly 32 is connected to the support portion 12 and can move with the drawer 1.

[0056] In one embodiment, the drive assembly 32 includes a slot member 321, a rotating gear 322, and a rotating shaft 323. The slot member 321 is fixedly disposed relative to the rotating gear 322 and the rotating shaft 323. The slot member 321 is rotationally engaged with the support portion 12. Specifically, when the support portion 12 is integrally disposed on the side wall of the drawer 1, the slot member 321 and the support portion 12 are rotationally engaged relative to each other. When the support portion 12 is rotationally disposed relative to the side wall of the drawer 1, the slot member 321 and the support portion 12 can be relatively fixedly engaged and rotationally disposed relative to the side wall of the drawer 1.

[0057] The rotating gear 322 is located between the slot member 321 and the third fixing member 35 and meshes with the reset plate 312, thereby enabling synchronous movement of the reset assembly 31 and the drive assembly 32. The rotating shaft 323 is fixedly passed through the slot member 321 and the rotating gear 322, and one end of the rotating shaft 323 is rotatably connected to the third fixing member 35, thereby enabling the drive assembly 32 to rotate relative to the third fixing member 35.

[0058] In one embodiment, the rotating shaft 323 includes a shaft body 3231 and a stopper 3232. The shaft body 3231 passes through the third fixing member 35, the rotating gear 322, and the slot member 321, and is fixed relative to the rotating gear 322 and the slot member 321. The stopper 3232 is provided at the end of the shaft body 3231.

[0059] The third fixing member 35 includes a stopper 351, a fixing body 352, a receiving cavity 353, and a through hole (not shown). The receiving cavity 353 is recessed from the end of the fixing body 352. The stopper 351 is located within the receiving cavity 353, and the through hole communicates with the receiving cavity 353. The end of the shaft body 3231 passes through the through hole, and the stopper 3232 is located within the receiving cavity 353. The diameter of the stopper 3232 is larger than the diameter of the shaft body 3231 and the aperture of the through hole to prevent the stopper 3232 from falling out of the receiving cavity 353.

[0060] The limiting portion 3232 contacts the stop portion 351 to limit the rotation angle of the rotating shaft 323, preventing the drive assembly 32 from rotating too far and hindering the movement of the drawer 1. Specifically, the limiting portion 3232 includes a first limiting rib 3233 and a second limiting rib 3234. When the drawer 1 is in the first assembly position, the first limiting rib 3233 contacts the stop portion 351. When the drawer is in the second assembly position, the second limiting rib 3234 contacts the stop portion 351.

[0061] The angle between the first limiting rib 3233 and the second limiting rib 3234 is no greater than 150 degrees. Preferably, the angle between the first limiting rib 3233 and the second limiting rib 3234 is no less than 90 degrees and no greater than 120 degrees. As the drawer 1 moves within the storage liner 2, the drive assembly 32 rotates accordingly. When the slot 321 is in a horizontal position, i.e., with the slot 321 opening toward the opening of the storage liner 2, the drawer 1 is in the second assembly position and is easiest to remove. When the slot 321 is in a vertical position, i.e., with the slot 321 opening toward the upper sidewall of the storage liner 2, the drawer 1 is in the first assembly position and is securely engaged within the storage liner 2. Therefore, when the angle between the first limiting rib 3233 and the second limiting rib 3234, i.e., the rotation angle of the rotating shaft 323, is between 90 and 120 degrees, the drawer 1 can be more easily pushed into and pulled out of the storage liner 2.

[0062] The present application also provides a cold storage device, comprising a housing (not shown) and the aforementioned drawer auxiliary movement device. The drawer auxiliary movement device is located within the housing. The cold storage device can be a refrigerator, freezer, or cold storage.

[0063] The cold storage equipment of the present application is provided with the above-mentioned drawer auxiliary moving device, so that the drawer 1 will move downward relatively when pulled out, avoiding the drawer 1 being blocked by the crossbeam when being pulled out or pushed into the storage liner 2, thereby improving the convenience of using the drawer and further enhancing the user experience and market competitiveness.

[0064] In the application, the left and right direction of the drawer 1 is represented by the X axis, the front and back direction of the drawer 1 is represented by the Y axis, and the depth (up and down) direction of the drawer 1 is represented by the Z axis. Figure 3 .

Although the present application has been disclosed as a preferred embodiment as above, it is not intended to limit the present application. Any technician familiar with this profession can make some changes or modifications to the equivalent embodiment of the above-disclosed technical content without departing from the scope of the technical solution of the present application.
