[0036] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any changes in structure, method, or function made by those of ordinary skill in the art based on these embodiments are included within the protection scope of the present invention.
[0037] Spatial relative position terms used herein, such as "upper", "lower", "left", "right", "front", "rear", etc., are used for the purpose of facilitating the description of the relationship between one feature and another as shown in the accompanying drawings. It can be understood that, depending on the placement position of the product, the spatial relative position terms may be intended to include different orientations other than those shown in the figures, and should not be construed as a limitation on the claims. In addition, the descriptive term "horizontal" used herein is not exactly equivalent to being perpendicular to the direction of gravity and allows for a certain degree of inclination.
[0038] As Figure 1 shown, a refrigeration device 100 provided by an embodiment of the present invention includes a box body 10, a door body 20, and a hinge assembly 30 connecting the box body 10 and the door body 20. The hinge assembly 30 enables the door body 20 to rotate relative to the box body 10, and the rotation of the door body 20 can open or close a compartment 40 formed inside the box body 10. The refrigeration device 100 can be a device such as a refrigerator or a beverage cabinet. In this embodiment, a refrigerator is taken as an example.
[0039] As Figures 2 - 4 shown in FIGS. 5 and 6, the hinge assembly 30 includes a first hinge member 1 connected to the box body 10, a second hinge member 2 connected to the door body 20, and the second hinge member 2 is rotatably connected to the first hinge member 1 so that the door body 20 can rotate relative to the box body 10.
[0040] The refrigeration device 100 further includes a first wire 101 led out from the inside of the box body 10 and a second wire 102 led out from the inside of the door body 20. The hinge assembly 30 further includes a conductive structure 3 at least partially embedded in the first hinge member 1. The first wire 101 and the second wire 102 are electrically connected through the conductive structure 3. The first wire 101 is specifically led out from the control module inside the box body 10, and the second wire 102 is specifically led out from the functional module inside the door body 20. The electrical connection between the first wire 101 and the second wire 102 enables signal transmission between the control module and the functional module and enables the control module to supply power to the functional module. Here, the functional module can be a touch screen, a button, a sensor, etc.
[0041] The first hinge member 1 includes a hinge plate 11 connected to the cabinet 10 and a hinge shaft 12 connected to the hinge plate 11. The second hinge member 2 includes a shaft sleeve 21 connected to the door body 20 and a shaft hole 22 formed in the shaft sleeve 21. The shaft hole 22 is used to accommodate the hinge shaft 12. The hinge shaft 12 can rotate within the shaft hole 22 so that the door body 20 can rotate relative to the cabinet 10. The shaft sleeve 21 moves synchronously with the door body 20 when the door body 20 rotates.
[0042] The conductive structure 3 includes an annular portion 31 sleeved around the periphery of the hinge shaft 12, a first extension portion 32 extending to one side in the axial direction of the hinge shaft 12, and a second extension portion 33 extending along the axial direction of the hinge shaft 12 and connecting the first extension portion 32 and the annular portion 31. The first wire 101 is electrically connected to one end of the first extension portion 32 away from the hinge shaft 12, and the second wire 102 is electrically connected to the annular portion 31. An annular groove 121 may be formed on the hinge shaft 12, and a part of the annular portion 31 is disposed in the annular groove 121 to fix the position.
[0043] When the door body 20 rotates, the position of the annular portion 31 remains unchanged, and the second wire 102 rotates with the door body 20. The annular portion 31 is annular, which can facilitate maintaining electrical connection with the second wire 102. Specifically, the hinge shaft 12 is located on one side in the length direction of the hinge plate 11, and the first extension portion 32 extends from one side in the length direction of the hinge plate 11 along the structural trend of the hinge plate 11 to the other side in the length direction of the hinge plate 11.
[0044] Specifically, as Figure 3 、 5 shown in -6, the shaft sleeve 21 includes a side wall 211 surrounding the shaft hole 22. The second hinge member 2 further includes a conductive ring 23 connected to the side wall 211. The conductive ring 23 has an inner peripheral surface 231 that contacts the outer peripheral surface of the annular portion 31. The second wire 102 is electrically connected to the annular portion 31 through the conductive ring 23. The contact between the outer peripheral surface of the annular portion 31 and the inner peripheral surface 231 of the conductive ring 23 provides a sufficient contact area, so that the signal or power transmission between the second wire 102 and the annular portion 31 can be kept stable.
[0045] Furthermore, the conductive ring 23 is made of a flexible material and has the ability of elastic deformation. A ring-shaped cavity 232 is formed between the conductive ring 23 and the side wall 211. The cross-section of the conductive ring 23 may specifically be in a C shape. The cavity 232 provides a space for the deformation of the conductive ring 23. An interference fit exists between the annular portion 31 and the conductive ring 23, that is, the diameter of the outer peripheral surface of the annular portion 31 is larger than the diameter of the inner peripheral surface 231 of the conductive ring 23. When the annular portion 31 contacts the conductive ring 23, the conductive ring 23 will elastically deform under the extrusion of the annular portion 31, so that the annular portion 31 and the conductive ring 23 can maintain close contact and does not affect the rotation of the shaft sleeve 21 relative to the hinge shaft 12.
[0046] The conductive ring 23 is preferably made of a metal material so as to be elastically deformable while having electrical conductivity. The shaft kit 21 is made of an insulating composite material, and the conductive ring 23 and the shaft kit 21 can be integrally formed.
[0047] In this embodiment, one end of the second wire 102 passes through the shaft kit 21 to extend into the cavity 232 and contact the conductive ring 23. An opening 212 for the second wire 102 to pass through is formed on the shaft kit 21. The second wire 102 has a contact end 1021 extending into the cavity 232, and the diameter of the contact end 1021 should be greater than the diameter of the opening 212 to prevent it from detaching from the cavity 232. The contact end 1021 specifically contacts the side of the conductive ring 23 opposite to the inner circumferential surface 231. In other embodiments, the contact end 1021 can also contact other parts of the conductive ring 23.
[0048] In this embodiment, as Figures 3 - 4 shown, a plurality of first wires 101, second wires 102, and conductive structures 3 are provided. The plurality of first wires 101, the plurality of second wires 102, and the plurality of conductive structures 3 are correspondingly arranged, that is, the plurality of first wires 101 and the plurality of second wires 102 are electrically connected in one-to-one correspondence through the plurality of conductive structures 3. The plurality of conductive structures 3 have a plurality of first extension parts 32, a plurality of second extension parts 33, and a plurality of annular parts 31. The plurality of first extension parts 32 are arranged at intervals, the plurality of annular parts 31 are arranged at intervals along the axis direction of the hinge shaft 12, the plurality of second extension parts 33 have different lengths to connect the plurality of first extension parts 32 and the plurality of annular parts 31 in one-to-one correspondence, and each conductive structure 3 extends along its own path. The plurality of annular parts 31 and the plurality of second extension parts 33 form a structure similar to a thread, so that the plurality of conductive structures 3 are closely arranged in the first hinge member 1 to save space.
[0049] As Figure 3 、 7 -8 The first extension part 32 has a connection part 321 exposed outside the hinge plate 11. The rest of the first extension part 32 and the second extension part 33 are covered by the first hinge member 1. The connection part 321 is used for electrically connecting with the first wire 101. Specifically, the hinge assembly 30 further includes a first terminal 4 connected to the hinge plate 11. The first terminal 4 is connected to the connection parts 321 of the plurality of first extension parts 32. The refrigeration device 100 further includes a second terminal 50 connected to the plurality of first wires 101. The second terminal 50 is plugged and connected to the first terminal 4. When the second terminal 50 is plugged into the first terminal 4, the plurality of second wires 102 and the plurality of connection parts 321 are electrically connected in one-to-one correspondence. Such a design makes the wiring convenient when the refrigeration device 100 is assembled.
[0050] The first terminal 4 includes a cover plate 41 and a plurality of conductive members 42 connected to the cover plate 41. The cover plate 41 is rotatably connected to the hinge plate 11, and a snap mechanism for fixing it to the hinge plate 11 is formed between the cover plate 41 and the hinge plate 11. When the cover plate 41 is fixed to the hinge plate 11, the plurality of conductive members 42 are in one-to-one contact with the plurality of connecting portions 321 and the plurality of first wires 101, so that the plurality of first wires 101 and the plurality of connecting portions 321 are in one-to-one electrical connection. The cover plate 41 can be made of an insulating composite material.
[0051] Specifically, a rotating shaft 111 is provided on one of the cover plate 41 and the hinge plate 11, and a rotating hole 411 is provided on the other. The cooperation between the rotating shaft 111 and the rotating hole 411 enables the cover plate 41 to be rotatably connected to the hinge plate 11. Figure 7 and Figure 8 As shown in the figure, the rotating hole 411 is provided on the cover plate 41 and the rotating shaft 111 is provided on the hinge plate 11. A snap 112 is provided on one of the cover plate 41 and the hinge plate 11, and a slot 412 is provided on the other. When the snap 112 is snapped into the slot 412, the cover plate 41 is fixed relative to the hinge plate 11. After the snap 112 is disengaged from the slot 412, the cover plate 41 can rotate relative to the hinge plate 11. Figure 7 and Figure 8 As shown in the figure, the slot 412 is provided on the cover plate 41 and the snap 112 is provided on the hinge plate 11.
[0052] In this embodiment, the refrigeration device 100 further includes a shield 60 covering the periphery of the hinge plate 11, the first terminal 4, and the second terminal 50. The shield 60 plays a protective role and can prevent the hinge plate 11, the first terminal 4, and the second terminal 50 from being exposed.
[0053] In this embodiment, the conductive structure 3 is made of a metal material and has conductivity. The first hinge member 1 is made of an insulating polymer material, and the conductive structure 3 and the first hinge member 1 are integrally formed. Specifically, when manufacturing, it is preferably to integrally inject mold the conductive structure 3 and the first hinge member 1 by co-injection molding.
[0054] The first hinge member 1 is made of a plastic material with sufficient strength and wear resistance, such as polyoxymethylene (POM) or nylon (PA) material, but not limited thereto. It can also be made of an insulating composite material with sufficient strength and wear resistance, so that the first hinge member 1 has sufficient strength to support the door body 20.
[0055] In other embodiments, the first hinge member 1 can also be made of a metal material, but in this case, an insulating layer should be provided between the conductive structure 3 and the first hinge member 1 and between the respective conductive structures 3.
[0056] For the refrigeration device 100 provided by the present invention, a first wire 101 led out from the box body 10 and a second wire 102 led out from the door body 20 are electrically connected through a conductive structure 3 embedded in the first hinge member 1. The first hinge member 1 can protect the conductive structure 3. The refrigeration device 100 does not need to be provided with a wire routing assembly, reducing the manufacturing cost of the refrigeration device 100 and making the appearance of the refrigeration device 100 more simple and concise.
