[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0031] In the related art, a rotating shaft fixedly connected to the door body is provided on both sides of the refrigerator door body. During installation, the door body needs to be moved and the rotating shafts on both sides of the door body are respectively installed in alignment with the shaft holes. The rotating shaft and the door body need to be moved as a whole for installation, which makes installation difficult.

[0032] In the door body assembly of the embodiment of the present application, the door body can rotate around the axis of the rotating shaft assembly, the first rotating shaft of the rotating shaft assembly is fixedly connected to the door body, and the second rotating shaft of the rotating shaft assembly is detachably connected to the door body. Compared with the related art, in which a structure of rotating shafts fixedly connected to the door body is provided on both sides of the door body, and the rotating shafts on both sides of the door body are respectively installed in alignment with the axis holes, and the rotating shafts and the door body need to be moved as a whole for installation and disassembly, the door body assembly of the embodiment of the present application can be installed by first aligning the first rotating shaft with the axis hole of the box body, and then installing the second rotating shaft to the door body, and then aligning the second rotating shaft with the other axis hole of the box body, without moving the rotating shaft and the door body as a whole for installation. When disassembly is required, it is only necessary to first separate the second rotating shaft from the door body, and then move the first rotating shaft out of the axis hole of the box body. There is no need to move the rotating shaft and the door body as a whole for disassembly. This makes it convenient for users to install and disassemble.

[0033] According to the first aspect of the present application, the present disclosure provides a door assembly, which can be used in a refrigerator. Figure 1 The door assembly includes a door 10 that can be rotated to open or close a refrigerator body 50. A refrigeration compartment can be formed in the refrigerator body 50, and the refrigeration compartment can be opened or closed by rotating the door.

[0034] Please combine Figure 2 The door assembly further includes a shaft assembly 20. The door 10 can rotate around the axis of the shaft assembly 20 to open or close the refrigeration compartment of the refrigerator. Figure 6 The axis MN of the shaft assembly 20 is shown in FIG. Figure 1 and Figure 2 , Figure 1 and Figure 2 The diagram in the figure shows the structure of the refrigerator when the cabinet is closed. When the cabinet is open, please refer to Figure 3 , Figure 3 Shown in FIG is a schematic structural diagram of the refrigerator when the refrigerator body is opened.

[0035] Please combine Figure 6 The rotating shaft assembly 20 includes a first rotating shaft 21 and a second rotating shaft 22. In the embodiment of the present application, the first rotating shaft 21 is fixedly connected to the door body 10. Specifically, the first rotating shaft 21 and the door body 10 can be integrally formed, or can be bonded to each other, and the second rotating shaft 22 is detachably connected to the door body to facilitate installation.

[0036] During installation, the first rotating shaft 21 can be installed in alignment with the shaft hole of the box body. The first rotating shaft 21 and the box body are rotatably connected, so that the side of the door body 10 fixedly connected to the first rotating shaft 21 can be installed on the box body. Then install the second rotating shaft 22 on the door body and align it with the other shaft hole of the box body. When disassembly is required, you only need to remove the second rotating shaft 22 first, and then move the first rotating shaft 21 out of the shaft hole of the box body. By setting the above structure, when the second rotating shaft 22 fails, the detachable structure allows the user to quickly locate and remove the faulty component, thereby shortening the maintenance time. At the same time, by replacing only the faulty component instead of the entire equipment or product, the detachable structure helps to reduce maintenance costs.

[0037] In some embodiments, please combine Figure 7 The door body 10 includes a first side wall 11. The door body assembly further includes a mounting member 30 connected to one end of the first side wall 11. The mounting member 30 and the first side wall 11 form an installation space 12. The installation space 12 and the door body 10 are arranged along a first direction. The hinge assembly 20 is installed in the installation space 12. Along the first direction, the projection of the hinge assembly 20 is within the projection of the first side wall 11.

[0038] In these embodiments, the installation space 12 and the door body 10 are arranged along a first direction. The rotating shaft assembly 20 is installed in the installation space 12, so that the rotating shaft assembly 20 and the door body 10 are arranged along the first direction. Since the projection of the rotating shaft assembly 20 along the first direction is within the projection of the door body 10, rather than being located outside the projection of the door body 10, the space required for installing the rotating shaft on both sides of the door body 10 can be reduced. For situations where the refrigerator needs to be placed in a narrow space (for example, the refrigerator is placed at the center armrest of the front seat, etc.), the embodiments of the present application reduce the space required for installing the rotating shaft on both sides of the door body, which can make the door body larger. Accordingly, the opening of the refrigeration compartment of the refrigerator body can be increased, making it easier for users to take and put items.

[0039] Please combine Figure 2 as well as Figure 7 In some embodiments, the door body 10 may further include a top wall 101, the first side wall 11 is connected to the top wall 101, and the first side wall 11 extends along a second direction at the same time, the second direction is perpendicular to the first direction, and along the first direction, the top wall 101 may protrude from the first side wall 11, and the portion of the top wall 101 protruding from the first side wall 11 may form the above-mentioned mounting member 30.

[0040] Please combine Figure 7In some embodiments, the door assembly may further include a mating assembly 40 installed in the installation space 12. In some examples, the mating assembly 40 may be connected to the mounting member 30 and installed in the above-mentioned installation space 12. The mating assembly 40 and the mounting member 30 may be integrally formed or bonded. In some examples, the mating assembly 40 may be connected to the first side wall 11 and installed in the installation space 12. The mating assembly 40 and the first side wall 11 may be integrally formed or bonded. In these embodiments, along the second direction, at least a portion of the second rotating shaft 22 is located between the mating assembly 40 and the mounting member 30, limiting the second rotating shaft 22 between the mating assembly 40 and the mounting member 30. Thus, the second rotating shaft 22 is limited along the second direction so that the second rotating shaft 22 cannot move along the second direction, and the second direction intersects with the first direction. In some embodiments, the second direction is perpendicular to the first direction.

[0041] Please combine Figure 7 In some embodiments, the mating assembly 40 includes a first mating portion 421. One end of the first mating portion 421 is connected to the mounting member 30, and the other end thereof extends in the second direction. Along the first direction, at least a portion of the second rotating shaft 22 is located between the first mating portion 421 and the first side wall 11. The first mating portion 421 and the mounting member 30 can be fixedly connected, for example, by integral molding or by adhesive bonding. The shape of the first mating portion 421 can be rectangular, parallelogram, triangular, or other shapes. In some examples, the shape of the first mating portion 421 can be rectangular. The first mating portion 421 and the first side wall 11 can be disposed opposite each other along the first direction. Along the first direction, at least a portion of the second rotating shaft 22 is located between the first mating portion 421 and the first side wall 11, thereby confining at least a portion of the second rotating shaft 22 between the first mating portion 421 and the first side wall 11. This prevents at least a portion of the second rotating shaft 22 from moving along the first direction.

[0042] In some embodiments, the mating assembly 40 further includes a second mating portion 422, which is connected to the end of the first mating portion 421 away from the mounting member 30. The second mating portion 422 and the first mating portion 421 may be integrally formed or bonded together. Along the second direction, at least a portion of the second rotating shaft 22 is located between the second mating portion 422 and the mounting member 30. This confines at least a portion of the second rotating shaft 22 between the second mating portion 422 and the mounting member 30, preventing at least a portion of the second rotating shaft 22 from moving along the second direction.

[0043] In some embodiments, the mating assembly 40 further includes a first mating member 41, which is fixedly connected to the first sidewall 11. The first mating member 41 may be integrally formed or fixedly connected by adhesive or other means. Along the second direction, at least a portion of the first rotating shaft 21 is located between the first mating member 41 and the mounting member 30, thereby further limiting the position of the first rotating shaft 21 along the second direction.

[0044] In some embodiments, the first mounting portion may include one of a slot and a buckle that cooperates with the mating component.

[0045] In some embodiments, the first mounting portion 221 may be provided with a slot 220 for cooperating with the mating component 40, the slot 220 including a second side wall 224 and a third side wall 225 spaced apart along the second direction, and at least part of the first mating component 41 is located between the second side wall 224 and the third side wall 225.

[0046] Please combine Figure 9 In some embodiments, the second rotating shaft 22 includes a first mounting portion 221 and a first shaft 223 connected thereto. The first shaft 223 can be mounted on one end of the first mounting portion 221. The first shaft 223 can be fixedly connected to the first mounting portion 221. Thus, the shaft 223 can be connected to the door body 10 simply by connecting the first mounting portion 221 to the door body 10. When the door body 10 is pulled to rotate relative to the housing, the shaft 223 rotates within the shaft hole of the housing.

[0047] In some embodiments, the first shaft 223 is used to be rotatably connected to the refrigerator body 50, wherein the refrigerator body 50 is provided with an axis hole, and the first shaft 223 is located in the axis hole. The first shaft 223 can rotate in the axis hole, thereby realizing the rotatable connection between the first shaft 223 and the refrigerator body 50.

[0048] In some embodiments, the second sidewall 224 can be closer to the mounting member 30. The first shaft 223 can be mounted on one end of the first mounting portion 221, or at least partially protrude from one side of the first mounting portion 221. The side of the slot 220 near the end of the first shaft 223 can have a first opening and a second opening that communicate with each other. The first opening is located on the side of the slot 220 facing away from the axis of the shaft assembly 20, and the second opening can be located on the side of the slot 220 facing away from the second shaft 231. This facilitates the insertion of the first mating member 41 into the slot 220 through the first and second openings during installation, thereby being constrained between the second sidewall 224 and the third sidewall 225. The side of the second sidewall 224 facing away from the second shaft 231 can have a mounting notch. During installation, the second mating portion 422 can move from the mounting notch toward the side near the third sidewall 225 and then push the second rotating shaft 22, allowing the second rotating shaft 22 to be positioned between the second sidewall 224 and the third sidewall 225.

[0049] Please combine Figure 7 In some embodiments, the second rotating shaft 22 includes a first stopper connected to the first mounting portion 221. The mounting member 30 includes a second stopper that cooperates with the first stopper to stop the second rotating shaft 22 in a third direction perpendicular to the first direction. Thus, the second rotating shaft 22 can be stopped in the third direction.

[0050] Please combine Figure 9 In some embodiments, the first position limiting member may include a fastener 226, the fastener 226 includes a convex portion 2261 and a connecting portion 2262, the connecting portion 2262 is connected to the first mounting portion 221, and the convex portion 2261 is provided on a side of the connecting portion 2262 away from the first shaft 223, so that the convex portion 2261 can be mounted on the first mounting portion 221. Figure 8 The mounting member 30 may be provided with a groove 31 cooperating with the protrusion 2261 to limit the second rotating shaft 22 along a third direction, which is perpendicular to the first direction.

[0051] Please combine Figure 9In some embodiments, the first mounting portion 221 defines a receiving slot 227 that engages with the fastener 226. The receiving slot 227 includes a bottom wall and a notch opposite the bottom wall. A protrusion 2261 is disposed adjacent to the notch of the receiving slot 227 and is movable in a second direction to move closer to or further from the bottom wall of the receiving slot 227. During installation, when the protrusion 2261 abuts the mounting member 30, it is pressed against the mounting member 30 and moves toward the side closer to the bottom wall of the receiving slot 227. When the protrusion 2261 moves to the groove 31, it no longer abuts the mounting member 30 and moves away from the bottom wall of the receiving slot 227. In other words, the protrusion 2261 moves toward the side closer to the mounting member 30, thereby being retained in the groove 31.

[0052] In other embodiments, the first limiting member may include a recessed portion, and the mounting member 30 may be provided with a protruding block. The block may be movable in the second direction to approach or move away from the second rotating shaft 22. The block is configured to cooperate with the recessed portion to limit the second rotating shaft 22 in the third direction. In these embodiments, when the second rotating shaft 22 is moved, the protruding block of the mounting member 30 may enter the recessed portion. In this manner, the block may protrude toward one side of the second rotating shaft 22 within the recessed portion, thereby being retained in the recessed portion.

[0053] In these embodiments, the number of parts required to realize the rotation function of the door body 10 is reduced, and at the same time, the assembly and disassembly of the door body 10 are simplified and convenient, thereby saving production costs and improving production and assembly efficiency.

[0054] Secondly, embodiments of the present application further provide a refrigerator comprising a housing 50 and the aforementioned door assembly. This refrigerator possesses all the benefits of the aforementioned door assembly, which are not further elaborated herein.

A shaft assembly 20 is rotatably coupled to the housing 50 to drive the door 10 to open or close the refrigeration compartment 51. The door 10 is rotatable about the axis of the shaft assembly 20.

[0055] Please combine Figure 4 In some embodiments, the housing 50 defines a first rotation axis hole 52 and a second rotation axis hole 53. The rotation axis assembly 20 includes a first rotation axis 21 and a second rotation axis 22. The first rotation axis 21 is fixedly connected to the door body 10, and the second rotation axis 22 is detachably connected to the door body. At least a portion of the first rotation axis 21 is mounted in the first rotation axis hole 52, and at least a portion of the second rotation axis 22 is mounted in the second rotation axis hole 53.

[0056] In some embodiments, during assembly, the first rotating shaft 21 can be directly pushed into the first rotating shaft hole 52, where the first rotating shaft 21 can rotate within the first rotating shaft hole 52. The second rotating shaft 22 can then be aligned with the second rotating shaft hole 53, where the second rotating shaft 22 can rotate within the second rotating shaft hole 53. The first mating portion 421, the second mating portion 422, and the first mating member 41 of the mating assembly 40 are then used to position the second rotating shaft in the first and second directions. Furthermore, the first and second limiting members are used to position the second rotating shaft in the third direction. In this manner, the second rotating shaft 22 is assembled into place.

[0057] Please combine Figure 4 In some embodiments, a damping member may be provided between the first rotating shaft 21 and the wall of the first rotating shaft hole.

[0059] In some embodiments, a damping member may be provided between the first rotating shaft 21 and the wall of the first rotating shaft hole, and a damping member may be provided between the second rotating shaft 22 and the wall of the second rotating shaft hole. The damping member may be a rubber damping member, a silicone damping member, a spring damping member, etc. This allows the door body 10 to stop at any angle during the opening process.

[0060] In some other embodiments, the first rotating shaft 21 may be a damping rotating shaft, and the second rotating shaft 22 may be a damping rotating shaft, so that the door body 10 can stop at any angle during the opening process.

[0061] Please combine Figure 3 、 Figure 5 as well as Figure 10 In some embodiments, the first rotating shaft 21 includes a first mounting portion 221 and a first shaft 223 connected to each other. The first shaft 223 is configured to be rotatably connected to the refrigerator body. The second rotating shaft 22 also includes a second shaft 231 and an elastic member 232. The second shaft 231 is mounted on a side of the first mounting portion 221 facing away from the first shaft 223. The elastic member 232 is sleeved on the second shaft 231. The refrigerator also includes a hook 70 that cooperates with the elastic member 232. In some embodiments, the elastic member 232 may be a torsion spring.

[0062] In these embodiments, during assembly, the first rotating shaft 21 can be directly pushed into the first rotating shaft hole 52, wherein the first rotating shaft 21 can rotate in the first rotating shaft hole 52. Then, the second rotating shaft 22 is aligned with the second rotating shaft hole 53, wherein the second rotating shaft 22 can rotate in the second rotating shaft hole 53. Then, the first matching portion 421, the second matching portion 422, and the first matching member 41 of the matching assembly 40 are used to limit the second rotating shaft in the first direction and the second direction. And the first limiting member and the second limiting member are used to limit the second rotating shaft in the third direction. Then, the pin of the torsion spring is clamped on the hook 70.
