[0043] The following will describe the implementation of the present invention in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these implementations are all within the scope of protection of the present invention.

[0044] Ginseng Figure 1 An embodiment of the present invention provides a refrigerator 100, which includes a cabinet 1, a door 2, a hinge mechanism 3 and a wiring device 4.

[0045] The box body 1 defines a storage room for storing items, which can be any one or a combination of a refrigerator, a freezer, and a temperature-changing room; the door body 2 is movably connected to the front of the box body 1 through a hinge mechanism 3, and has a closed position and an open position. When the door body 2 is in the closed position, the door body 2 seals the front exit of the storage room; when the door body 2 is in the open position, the door body 2 opens the front exit of the storage room for users to take and put items.

[0046] In this embodiment, the refrigerator 100 can specifically be a built-in refrigerator, and accordingly, the hinge mechanism 3 is configured as a built-in hinge, that is, when the door body 2 changes from the closed position to the open position, the door body 2 moves forward and rotates from the closed position, and its movement trajectory does not have a fixed pivot axis.

[0047] Ginseng Figures 2a to 3 The wiring device 4 includes a wiring assembly 40 , a pivot 21 disposed on the door body 2 , and a wiring mechanism 10 disposed on the box body 1 .

[0048] Ginseng Figure 4 The wiring assembly 40 includes a wiring box 41 extending longitudinally approximately in the front-to-back direction and a sleeve 42 connected to the longitudinal front end of the wiring box 41. The longitudinal rear end of the wiring box 41 extends into the outlet mechanism 10 at the box body 1, and the wiring box 41 can at least move forward relative to the outlet mechanism 10; the sleeve 42 is plug-fitted with the pivot 21 and the two can rotate relative to each other. Therefore, on the one hand, the wiring harness 5 can be introduced from the outlet mechanism 10 to the pivot 21 through the wiring assembly 40, and on the other hand, through the relative rotation of the sleeve 42 and the pivot 21 and the forward movement of the wiring box 41 relative to the outlet mechanism 10, it is ensured that the wiring assembly 40 can move forward and rotate with the door body 2, thereby realizing the wiring between the box body 1 and the door body 2 of the built-in refrigerator 100.

[0049] Preferably, Figure 2a The outlet mechanism 10 is an outlet box with an opening 11 facing the door body 2, and the longitudinal rear end of the wiring box 41 extends into the outlet box through the opening 11, and there is any one or a combination of a front-to-back movement gap, a left-to-right movement gap, and an up-and-down movement gap between the wiring box 41 and the outlet box. In this embodiment, the wiring box 41 and the outlet box have a front-to-back movement gap so that they can move relative to each other, a left-to-right movement gap so that they can move relative to each other, and an up-and-down movement gap so that they can move relative to each other.

[0050] Further, Figure 2bThe door body 1 includes a thermal insulation layer formed by foaming and a frame 20 shielding the thermal insulation layer, and the wiring assembly 40 is located between the hinge mechanism 3 and the frame 20, so that the wiring harness 5 can be pulled without being interfered by the hinge mechanism 3. In this embodiment, the hinge mechanism 3 is located on the upper part of the door body 2, and the wiring assembly 40 is located below the hinge mechanism 3 in the vertical direction.

[0051] Ginseng Figure 3 as well as Figures 5a to 5c , the pivot 21 extends vertically and is hollow, so that the sleeve 42 is inserted into the pivot 21; and the wiring device 4 also includes a wire groove 22 connected to the bottom of the pivot 21, and the wire harness 5 extends from the sleeve 42 through the pivot 21 to the wire groove 22, and is routed along the wire groove 22. In this embodiment, the pivot 21 and the wire groove 22 are formed on the frame 20, specifically, an inner concave structure integrally formed on the frame 20. In this way, by arranging the pivot 21 and the wire groove 22 on the frame 20, it is not necessary to pre-embed the wire harness 5 in the insulation layer, the installation of the wire harness 5 is convenient, and the overflow of the foaming material caused by opening a hole on the frame 20 for passing the wire is avoided, and the degradation of the wire harness 5 due to the influence of the foaming process is avoided.

[0052] Further, Figure 2b The wiring device 4 also includes a gland 23 fastened to the frame 20 by screws or hooks. Figure 5c and Figure 6 The pressure cover 23 is an integrally formed structure, which includes a bushing 231 and a pressure holding portion 232 .

[0053] The pressing portion 232 extends into the wire groove 22, and the pressing portion 232 and the groove wall of the wire groove 22 clamp the wire harness 5 together, thereby pressing the wire harness 5 tightly, thereby preventing the wire harness 5 at the wire groove 22 from being pulled and entangled or broken during the door opening and closing process.

[0054] The bushing 231 is sleeved between the shaft sleeve 42 and the pivot 21; specifically, the bushing 231 is inserted into the pivot 21, and the shaft sleeve 42 is inserted into the bushing 231 and can rotate relative to the bushing 231, that is, the shaft sleeve 42, the bushing 23 and the pivot 21 are sleeved in sequence from the inside to the outside.

[0055] Further, Figure 4, the wiring box 41 is assembled and connected with the sleeve 42. Specifically, the wiring box 41 has an assembly structure 410, and the sleeve 42 is assembled and connected to the assembly structure 410. In the preferred embodiment, the wiring box 41 has two assembly structures 410, and the sleeve 42 can be detachably connected to one of the two assembly structures 410, that is, according to actual use, the sleeve 42 can be selectively connected to one of the assembly structures 410, or it can be removed from the assembly structure 410 and connected to the other assembly structure 410. Therefore, by providing two assembly structures 410 on the wiring box 41, two different assembly modes of the wiring assembly 40 can be realized to be suitable for different refrigerator products.

[0056] As in this embodiment, Figures 2a to 3 , the refrigerator 100 is configured to have a structure that allows for interchangeable left and right door openings. Specifically, the door body 2 is a left-right symmetrical structure, which includes two hinge mounting parts 24 symmetrically arranged on the left and right sides, and one of the two hinge mounting parts 24 is detachably equipped with a hinge mechanism 3, so that the door body 2 is movably connected to the box body 1. As shown in the accompanying drawings, the hinge mounting part 24 on the right is equipped with the hinge mechanism 3 while the hinge mounting part 24 on the left is not equipped with the hinge mechanism 3, and the refrigerator 100 is a left-side door opening; and according to actual needs, the hinge mounting part 24 on the right may not be equipped with the hinge mechanism 3 while the hinge mounting part 24 on the left may be equipped with the hinge mechanism 3, and the refrigerator 100 is a right-side door opening.

[0057] Correspondingly, the wiring device 4 includes two pivots 21 symmetrically arranged on the left and right sides of the frame 20 , and two wire outlet mechanisms 10 symmetrically arranged on the left and right sides of the box body 1 . When the hinge mounting portion 24 on the left is equipped with the hinge mechanism 3, the sleeve 42 is matched with one of the two assembly structures 410, the sleeve 42 and the left pivot 21 can be plugged and matched for relative rotation, and the longitudinal rear end of the wiring box 41 can at least be relatively moved forward to adapt to the outlet mechanism 10 on the left. In this embodiment, the wiring box 41 can be inserted into the outlet mechanism 10 on the left to move forward and backward, left and right, and up and down; and as shown in the accompanying drawings, when the hinge mounting portion 24 on the right is equipped with the hinge mechanism 3, the sleeve 42 is matched with the other of the two assembly structures 410, the sleeve 42 and the right pivot 21 can be relatively rotated and plugged and matched, and the longitudinal rear end of the wiring box 41 can at least be relatively moved forward to adapt to the outlet mechanism 10 on the right. In this embodiment, the wiring box 41 can be inserted into the outlet mechanism 10 on the right to move forward and backward, left and right, and up and down. Therefore, the wiring device 4 of the present invention can realize two different assembly modes of the shaft sleeve 42 and the wiring box 41, so it is suitable for built-in refrigerators with interchangeable left and right doors.

[0058] Preferably, the wiring device 4 includes two wire grooves 22 symmetrically arranged on the left and right sides of the frame 20, and the two wire grooves 22 correspond to the two pivots 21 one by one, that is, each pivot 21 is connected to a corresponding wire groove 22. In this embodiment, in the left and right directions, the two pivots 21 are respectively located at the left and right ends of the frame 20, and the two wire grooves 22 extend from the corresponding pivots 21 to the middle of the frame 20. In this way, it is possible to route the wires from the middle of the frame 20 to the bottom of the door body 2, so that the matching terminal of the wire harness 5 is configured in the middle of the frame 20, and the matching terminal can be conveniently connected to the wire harness 5 in the two wire grooves 22.

[0059] Furthermore, in this embodiment, the two assembly structures 410 are symmetrically arranged up and down, thereby further reducing the difficulty of designing the shaft sleeve 42 .

[0060] Ginseng Figure 4 as well as Figures 7a to 8c , the detailed structure of the routing component 40 according to an embodiment of the present invention is further introduced.

[0061] Specifically, the wiring box 41 includes a box body 411 extending longitudinally approximately along the front-to-back direction, a box cover 412 assembled with the box body 411, a first end having a wiring opening 413, and a second end longitudinally opposite to the first end, wherein the first end is also the rear end of the wiring box 41, and the second end is also the front end of the wiring box 42.

[0062] The box body 411 has a wiring cavity 414 extending from the wiring opening 413 to the second end. The wiring cavity 414 is connected to the outside of the wiring box 41 through the wiring opening 413. Thus, the wiring harness 5 can extend along the wiring cavity 414 and pass through the wiring opening 413 to leave the wiring box 41 and enter the outlet mechanism 10.

[0063] In the present invention, the assembly structure 410 is located at the second end, and includes an assembly hole 417 surrounded by an edge 415 of the box body 411 and an edge 416 of the box cover 412; the sleeve 42 includes a groove 421 formed on its outer wall, and the hole wall of the assembly hole 417 is clamped in the groove 421, thereby realizing the matching of the sleeve 42 and the assembly structure 410, and the wiring cavity 414 is connected to the inner hole of the sleeve 42 at the second end. In this way, the sleeve 42 is clamped between the box body 411 and the box cover 412. In the process of arranging the wiring harness 5 in the wiring assembly 40, the wiring harness 5 can be firstly arranged in the wiring cavity 414 in the box body 411 and the inner hole of the sleeve 42, and then the connection between the wiring box 41 and the sleeve 42 can be completed by buckling the box body 411 and the box cover 412, thereby completing the arrangement of the wiring harness 5, facilitating assembly, and avoiding the inconvenience of operation caused by the wiring harness 5.

[0064] Furthermore, the hole wall of the assembly hole 417 and the groove 421 are close to each other, and the two are arranged to be circles of equal diameters. In this way, the shaking of the shaft sleeve 42 relative to the wiring box 41 perpendicular to the axis of the shaft sleeve 42 can be restricted.

[0065] Preferably, the box body 411 also has a longitudinal opening 4140 exposing the wiring cavity 414, and the opening 4140 is connected to the wiring port 413 and the assembly hole 417. The box cover 412 is buckled at the opening 4140 to shield the wiring cavity 414. Therefore, by providing the opening 4140, the wiring harness 5 can be clamped into the wiring cavity 414 from the opening 4140, avoiding cumbersome operation or bending of the wiring harness 5 caused by threading the wiring into the wiring cavity 414.

[0066] Furthermore, the box body 411 and the box cover 412 are fastened together by a snap-fit ​​structure and / or a threaded structure.

[0067] Specifically, the box body 411 is generally in a U-shaped structure, which includes an upper end plate 4111, a lower end plate arranged opposite to the upper end plate 4111, and a side plate 4112 connected between the upper end plate 4111 and the lower end plate, the side plate 4112 is arranged opposite to the opening 4140, and the wiring cavity 414 is formed between the upper end plate 4111 and the lower end plate and is arranged close to the side plate 4112. At least one of the upper end plate 4111 and the lower end plate is fastened to the box cover 412 through a snap structure and a threaded structure. In this embodiment, the upper end plate 4111 and the lower end plate are both fastened to the box cover 412 through a snap structure 441, and the upper end plate 4111 is fastened to the box cover 412 through a threaded structure 43 such as screws and bolts. In this way, the matching firmness of the box body 411 and the box cover 412 can be enhanced to avoid accidental disengagement due to loose connection.

[0068] Furthermore, the box body 411 has a box body end 418 located on the side of the assembly hole 417 away from the first end (i.e., the front side of the assembly hole 417), and the box cover 412 has a box cover end 419 located on the side of the assembly hole 417 away from the first end (i.e., the front side of the assembly hole 417); the box body end 418 and the box cover end 419 are also fastened and connected by a buckle structure. In this way, the connection firmness of the box body 411 and the box cover 412 can be strengthened to avoid the problem of expansion of the assembly hole 417 and accidental detachment of the shaft sleeve 42 due to loose connection.

[0069] Preferably, the assembly structure 410 further includes a limiting portion 4101, and the sleeve 42 includes a limited portion 422, and the limiting portion 4101 cooperates with the limited portion 422 to limit the sleeve 42 from rotating relative to the wiring box 41 around the axis of the sleeve 42. In this embodiment, the axis of the sleeve 42 extends vertically and is perpendicular to the longitudinal extension direction of the box body 411. Thus, it can be ensured that the sleeve 42 and the wiring box 41 will not rotate relative to each other, thereby preventing the wiring harness 5 from being damaged by friction due to the relative rotation of the sleeve 42 and the wiring box 41 during the door opening and closing process.

[0070] In this embodiment, the assembly structure 410 includes two limiting parts 4101, one of which is disposed on the box body 411, and the other of which is disposed on the box cover 412; correspondingly, the shaft sleeve 42 includes two limited parts 422 corresponding to the two limiting parts 4101. In this way, on the one hand, the shaft sleeve 42 can be accurately docked with the box body 411 and the box cover 412 respectively, and on the other hand, there will be no relative rotation between the shaft sleeve 42 and the box body 411, and between the shaft sleeve 42 and the box cover 412, thereby ensuring the structural stability.

[0071] Further, each limiting portion 4101 and the corresponding limited portion 422 are configured as a hole structure and the other is configured as a protrusion that fits into the hole structure. As shown in the embodiment of the attached drawings, the two limited portions 422 are configured as protrusions that protrude outward from the outer wall of the shaft sleeve 42, and correspondingly, the limiting portion 4101 on the box body 411 is configured as a groove structure, and the limiting portion on the box cover 412 is configured as a hole structure.

[0072] Preferably, the two limited portions 422 are centrally symmetrically arranged, and correspondingly, the two limited portions 4101 are also centrally symmetrically arranged, which can reduce the difficulty of alignment between the sleeve 42 and the wiring box 41 during assembly and facilitate operation.

[0073] Compared with the prior art, this embodiment has the following beneficial effects: by clamping the sleeve 42 between the box body 411 and the box cover 412, when wiring is performed in the wiring assembly 40, the wiring harness 5 can be first arranged in the wiring cavity 414 in the box body 411 and in the inner hole of the sleeve 42, and then the wiring box 41 and the sleeve 42 can be connected by snapping the box body 411 and the box cover 412, thereby completing the arrangement of the wiring harness 5, facilitating assembly, and avoiding the inconvenience of operation caused by the wiring harness threading.

[0074] The detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. All equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
