[0037] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0038] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0039] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0040] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0041] In order to facilitate the drawer-type structure of the refrigerator to realize functions such as display control, heating, sterilization and deodorization, it is usually necessary to provide a power supply circuit for supplying power to each functional component in the drawer-type structure of the refrigerator. At the same time, the circuit arranged in the refrigerator body 1 is connected to the circuit of the drawer-type structure, so as to realize power supply to the drawer-type structure, so that the drawer-type structure can realize functions such as display control, heating, sterilization and deodorization.

[0042] In the existing technology, there are two main ways to supply power to the drawer-type structure of the refrigerator. One is to connect a spring wire or a tank belt or other structure between the box body 1 and the drawer-type structure; the power supply line in the box body 1 supplies power to the drawer-type structure that can push and pull the spring wire or the tank belt, thereby satisfying the drawer-type structure to realize display control, heating, sterilization and deodorization and other functions; the other is to use wireless power supply to power the drawer-type structure.

[0043] When power is supplied by connecting a spring wire or a tank belt between the box 1 and the drawer-type structure, the spring wire or the tank belt is easily damaged and difficult to repair, and the spring wire or the tank belt takes up more space; when the drawer-type structure is powered by wireless power supply, the wireless power supply method will produce a large error as the distance increases, and the structure of the wireless power supply is also relatively complex, and the production difficulty is also relatively high.

[0044] In order to solve the technical problems existing in the prior art, the present application provides a drawer assembly and a refrigerator with a power supply device.

[0045] like Figure 1 , Figure 2 , Figure 3 and Figure 4 shown. Figure 1 This is a structural schematic diagram of a drawer assembly according to an embodiment of the present application; Figure 2 for Figure 1 A partial enlarged view of part I; Figure 3 This is a structural schematic diagram of a drawer body of another embodiment of the present application; Figure 4 This is a bottom view of a drawer body according to another embodiment of the present application.

[0046] In some embodiments, a drawer assembly with a power supply device provided in the present application includes: a box 1, a drawer body 2, a first contact 402 and a second contact 201. The box 1 is provided with a front opening, and the front opening is used to accommodate the drawer body 2.

[0047] The drawer body 2 is slidably connected to the box body 1, and can be pushed, pulled and slid through the front opening; the first contact 402 is used to connect the power supply line in the box body 1, the first contact 402 is slidably connected to the box body 1, and a sliding groove is also provided on the inner wall of the front opening, and the opening direction of the sliding groove is vertically set, the first contact 402 is located in the sliding groove, the first contact 402 is slidably connected to the inner wall of the sliding groove, and the first contact 402 can reciprocate toward the drawer body 2.

[0048] The second contact 201 is fixedly connected to the bottom wall of the drawer body 2 , and the power supply line arranged in the drawer body 2 is electrically connected to the second contact 201 . The bottom wall of the second contact 201 and the bottom wall of the drawer body 2 are located in the same plane.

[0049] Among them, a first magnet 403 is slidably connected to the inner wall of the sliding groove, and the first magnet 403 is fixedly connected to the first contact 402, and both the first magnet 403 and the first contact 402 can move along the sliding groove toward the side close to the drawer body 2, and the first magnet 403 and the first contact 402 are both located at the bottom of the drawer body 2; the drawer body 2 is connected to the second magnet 5 by bonding, the second magnet 5 is magnetically attracted to the first magnet 403, and the end face of the first contact 402 close to the second contact 201 and the end face of the first magnet 403 close to the second magnet 5 are located in the same plane.

[0050] When the drawer body 2 is stored in the box body 1, the first magnet 403 and the second magnet 5 are magnetically attracted to each other, and the first contact 402 and the second contact 201 are electrically connected, so that the power supply circuit in the box body 1 is electrically connected to the power supply circuit set in the drawer body 2, so as to facilitate the drawer body 2 to realize display control, heating, sterilization and deodorization functions; when the drawer body 2 is pulled toward the outside of the box body 1, the drawer body 2 slides along the front opening of the box body 1, and the first magnet 403 and the second magnet 5 slide along the side perpendicular to the end face of the first magnet 403, the first magnet 403 is separated from the second magnet 5, and the first contact 402 is separated from the second contact 201, and the first contact 402 and the first magnet 403 are moved along the sliding groove toward the side away from the drawer body 2 under the action of gravity, thereby reducing the probability of the first contact 402 and the first magnet 403 hindering the sliding of the drawer body 2, and at the same time, the purpose of reliably powering the power supply circuit in the drawer body 2 can be achieved.

[0051] In some embodiments, the drawer assembly provided in the present application can also be implemented as follows: the first magnet 403 or the second magnet 5 is replaced by a metal material having a magnetic moment between molecular structures, such as nickel, iron, cobalt, etc.; when the first magnet 403 is replaced by a metal material having a magnetic moment between molecular structures, the second magnet 5 is implemented as a magnetic material; when the second magnet 5 is replaced by a metal material having a magnetic moment between molecular structures, the first magnet 403 is implemented as a magnetic material.

[0052] When the drawer body 2 slides along the inner wall of the box body 1, the first magnet 403 and the second magnet 5 are misaligned in the horizontal direction, thereby reducing the contact area between the first magnet 403 and the second magnet 5, and weakening the magnetic force between the first magnet 403 and the second magnet 5, so that the first magnet 403, under the action of gravity, drives the first contact 402 away from the drawer body 2, and disconnects the first contact 402 from the second contact 201, thereby reducing the probability of electric shock to people after the drawer body 2 is pulled out of the box body 1.

[0053] In some embodiments, in addition to setting the first contact 402, the second contact 201, the first magnet 403 and the second magnet 5 on the bottom wall of the front opening of the box body 1, the first contact 402, the second contact 201, the first magnet 403 and the second magnet 5 provided in the drawer assembly provided in the present application can also be set on other side walls of the front opening. When the first contact 402, the second contact 201, the first magnet 403 and the second magnet 5 can also be set on other side walls of the front opening, a reset structure is connected between the first contact 402 and the first magnet 403 and the box body 1. The reset structure can be implemented as a spring or an elastic band, etc., which drives the first contact 402 and the first magnet 403 to shrink into the sliding groove after the magnetic force between the first magnet 403 and the second magnet 5 is weakened through the elastic material, thereby reducing the probability of the first contact 402 hindering the drawer body 2 from sliding, and improving the reliability of pulling the drawer body 2 to move.

[0054] Reference Figure 5 and Figure 6 , Figure 5 This is a schematic structural diagram of a liner box of a drawer assembly according to another embodiment of the present application; Figure 6 This is a schematic structural diagram of a sliding block of a drawer assembly, a first contact point, and a first magnet in a combined state according to another embodiment of the present application.

[0055] In some embodiments, the drawer assembly with a power supply device provided in the present application also includes a lining box 3, which is a rectangular parallelepiped with an opening at the top. The lining box 3 is connected to the sliding groove by bonding, and the top opening of the lining box 3 is located at the bottom of the drawer body 2. When the drawer body 2 is completely stored in the box body 1, the top opening of the lining box 3 is located at the bottom of the second magnet 5 and the second contact 201; the first magnet 403 and the first contact 402 are both located in the lining box 3, and the first magnet 403 and the first contact 402 can slide toward the top opening along the lining box 3 under the adsorption action of the magnetic force of the second magnet 5, so that the first contact 402 is electrically connected to the second contact 201.

[0056] By setting a lining box 3 on the surrounding side of the first magnet 403 and the first contact 402, the probability of friction between the first magnet 403 and the first contact 402 and the outer wall of the sliding groove is reduced, and the first magnet 403 reciprocates toward the drawer body 2 under the protection of the lining, while improving the efficiency of replacing the lining at a later time, reducing the cost required to maintain the electrical connection between the first contact 402 and the second contact 201, and improving the first magnet 403 to drive the first contact 402 to move and then achieve electrical connection with the second contact 201, so as to realize the reliability of supplying power to the power supply line in the box body 1 through the connection between the first contact 402 and the second contact 201 toward the line set in the drawer body 2.

[0057] In some embodiments, the drawer assembly with a power supply device provided in the present application also includes a sliding block 4, which is located inside the lining box 3, and the sliding block 4 is slidably connected to the lining box 3; at the same time, the first magnet 403 and the first contact 402 are fixedly connected to the sliding block 4, and the first magnet 403 and the first contact 402 are fixedly connected to the top of the sliding block 4 by bonding, and the first magnet 403 and the first contact 402 are staggered in the horizontal direction, and the first contact 402 is arranged corresponding to the second contact 201 in the vertical direction, and the first magnet 403 is arranged corresponding to the second magnet 5 in the vertical direction.

[0058] When the drawer body 2 is stored in the box body 1, the first magnet 403 drives the sliding block 4 to slide along the inner wall of the lining box 3 under the action of the magnetic force of the second magnet 5, and the first contact 402 moves toward the second contact 201 under the drive of the sliding block 4. When the first magnet 403 and the second magnet 5 are connected as a whole under the action of magnetic adsorption, the first contact 402 and the second contact 201 are electrically connected, so that the power supply circuit in the box body 1 is connected with the power supply circuit set in the drawer body 2; when the drawer body 2 gradually leaves the box body 1 during the pulling process, the first magnet 403 and the second magnet 5 slide in the horizontal direction, and the relative area between the first magnet 403 and the second magnet 5 Gradually decreases, so that the force of mutual attraction between the first magnet 403 and the second magnet 5 gradually decreases, and the sliding block 4, the first contact 402 and the first magnet 403 slide along the inner wall of the lining box 3 toward the side away from the drawer body 2 under the action of gravity, and the first contact 402 is separated from the second contact 201. At the same time, the top wall of the first contact 402 is lower than the top wall of the sliding groove, so as to reduce the probability of the first contact 402 obstructing the drawer body 2 and improve the smoothness of pushing the drawer body 2 to reciprocate. The first contact 402 and the second contact 201 are connected as a whole under the action of the first magnet 403 and the second magnet 5, thereby improving the reliability of power supply to the power supply line set in the drawer body 2.

[0059] In some embodiments, the inner wall of the liner box 3 provided in the present application is fixedly connected with a guide column 301, the length direction of the guide column 301 is parallel to the opening direction of the liner box 3, and the guide column 301 is implemented as a cylinder or a rectangular parallelepiped; the sliding block 4 is provided with a guide groove 401 for cooperating with the guide column 301, and the guide column 301 is slidably connected to the inner wall of the guide groove 401.

[0060] When the first magnet 403 slides under the action of the magnetic force of the second magnet 5, the sliding block 4 slides along the length direction of the guide column 301 under the guidance of the guide column 301. By setting the guide column 301, the probability of the sliding block 4 flipping when moving on the inner wall of the lining box 3 is reduced, thereby reducing the probability of misalignment at the connection between the first contact 402 and the second contact 201, thereby improving the reliability of the power supply line in the box body 1 to supply power to the drawer body 2.

[0061] In some embodiments, the guide pillars 301 provided in the present application are implemented in plurality, and the plurality of guide pillars 301 are evenly distributed along the circumference of the liner box 3, and the circumferential side of the sliding block 4 is provided with guide grooves 401 whose positions and quantities match the guide pillars 301, and each guide pillar 301 extends into a guide groove 401, and the guide pillar 301 is slidably connected to the inner wall of the guide groove 401.

[0062] By providing a plurality of guide posts 301 matched with the guide grooves 401 , the probability of the sliding block 4 flipping over when moving on the inner wall of the liner box 3 is reduced, thereby improving the reliability of the electrical connection between the first contact 402 and the second contact 201 .

[0063] In some embodiments, the bottom wall of the sliding block 4 is also fixedly connected to a limiting step 404 by integral molding. The size of the limiting step 404 is larger than that of the sliding block 4, and the outer wall of the limiting step 404 fits the inner wall of the lining box 3. The limiting step 404 and the sliding block 4 can slide up and down along the inner wall of the lining box 3; the limiting buckle 302 is integrally fixed to the top of the lining box 3, and the inner wall of the limiting buckle 302 protrudes from the inner wall of the lining box 3, which is used to limit the limiting step 404 in the lining box 3.

[0064] The bottom wall of the limit buckle 302 fits with the top wall of the limit step 404. When the first magnet 403 and the second magnet 5 are adsorbed under the action of magnetic force, the first contact 402 is electrically connected to the second contact 201 and supplies power to the power supply line arranged in the drawer body 2; when the operator pulls the drawer body 2 to move, the limit buckle 302 and the limit step 404 cooperate, thereby reducing the probability of the sliding block 4 detaching from the lining box 3 and improving the reliability of the sliding block 4 supporting the first contact 402 and the second contact 201.
