Description

Refrigerator power supply harness threading mechanism and refrigerator Technical Field

[0001] This application relates to the field of refrigerator technology, and in particular to a refrigerator power supply harness threading mechanism and a refrigerator. Background Technology

[0002] Electrically powered components such as lights and ambient lights on the cabinet door need to be connected to the power supply on the cabinet via power supply harnesses. In the relevant structure, a harness threading mechanism is typically used to run the power supply harness between the cabinet door and the cabinet body. This harness threading mechanism includes a push rod, a hinge box, and a harness box. The hinge box is used to install to the cabinet body, and the harness box is used to install to the door. One end of the push rod is movable within the hinge box, while the other end extends out of the hinge box and is hinged to the harness box. The harness inside the hinge box passes through the push rod and then extends from the end of the push rod that is hinged to the harness box, connecting to the harness box.

[0003] However, because only the end of the push rod that is hinged to the wiring harness box is constrained, while the end that moves within the hinge box is unconstrained, the trajectory of the moving end of the push rod within the hinge box is unpredictable and unstable during the opening or closing of the door. This results in significant shaking and noise from the push rod, increasing wear and shortening its lifespan. Furthermore, the significant shaking of the push rod also causes movement of the wiring harness within the hinge box, further exacerbating harness wear. Summary of the Invention

[0004] Therefore, it is necessary to provide a refrigerator power supply harness threading mechanism and refrigerator that can constrain the end of the push rod located inside the hinge box, thereby preventing the push rod from wobbling significantly inside the hinge box.

[0005] A refrigerator power supply wiring harness threading mechanism includes a push rod, a hinge box, and a wiring harness box. The hinge box is used to install to the refrigerator body, and the wiring harness box is used to install to the door. One end of the push rod is movably located inside the hinge box, and the other end extends out of the hinge box and is hinged to the wiring harness box. The refrigerator power supply wiring harness threading mechanism also includes a slide rail, a slider, and a hinge shaft. The slide rail is located inside the hinge box and on one side of the push rod. The slider is slidably connected to the slide rail, and the side wall of the push rod is hinged to the slider through the hinge shaft. As the door opens, the push rod can rotate around the hinge shaft and move out of the hinge box along the slide rail. As the door closes, the push rod can rotate around the hinge shaft and move inwards along the slide rail into the hinge box.

[0006] In one embodiment, the push rod sidewall is provided with a first protrusion, and the slider sidewall is provided with a second protrusion, the first protrusion and the second protrusion being rotatably connected around a hinge axis.

[0007] In one embodiment, one end of the hinge shaft is fixedly connected to one of the first protrusion and the second protrusion, and the other of the first protrusion and the second protrusion has a locking hole. The other end of the hinge shaft is movably inserted through the locking hole and is elastically snapped into the locking hole.

[0008] In one embodiment, the hinge shaft includes a plurality of elastic retaining strips spaced apart around its own axial direction, with a deformation gap formed between two adjacent elastic retaining strips; each elastic retaining strip has a first segment and a second segment, the first segment being fixedly connected to a first protrusion or a second protrusion, and the cross-sectional area of ​​the hinge shaft in the first segment being smaller than the cross-sectional area in the second segment; wherein, as the hinge shaft is inserted into the retaining hole from the end where the second segment is located, the plurality of elastic retaining strips can move closer to each other in response to the compression of the inner wall of the retaining hole, until the second segment passes through the retaining hole, at which point the elastic retaining strips reset and the second segment stops at the outer periphery of the retaining hole.

[0009] In one embodiment, along the direction from the second segment to the first segment, the cross-sectional area of ​​the hinge shaft in the second segment gradually increases and then gradually decreases.

[0010] In one embodiment, the slide rail extends along the front-to-back direction x of the refrigerator. The slide rail is spaced apart from and encloses one side inner wall of the hinge box to form a receiving space. As the door opens or closes, the push rod moves within the receiving space.

[0011] In one embodiment, the slider has a slot, and the slider slides and is locked onto the upper end surface of the slide rail along the height z direction of the refrigerator through the slot.

[0012] In one embodiment, the upper surface of the slide rail along the height direction z of the refrigerator is configured as an arc surface, and the slot is configured as a U-shaped groove.

[0013] In one embodiment, the slider has a cavity, and slots are formed on two side walls of the slider along the front-rear direction x of the refrigerator, and the slots communicate with the cavity.

[0014] A refrigerator includes a cabinet, a door, a power supply harness, and a power supply harness threading mechanism as described in any of the above embodiments. The power supply harness threading mechanism includes a push rod, a hinge box, and a harness box. The hinge box is installed to the cabinet, and the harness box is installed to the door. One end of the push rod is movably located inside the hinge box and has a first hole, while the other end extends out of the hinge box and is hinged to the harness box. The end of the push rod that is hinged to the harness box has a second hole. The power supply harness passes through the hinge box, through the first hole, into the push rod, and through the second hole out of the push rod. The power supply harness is then connected to the harness box.

[0015] Compared with existing technologies, the refrigerator power supply harness threading mechanism and refrigerator provided in this application allow the movement trajectory of the push rod to be decomposed into rotation around the hinge axis and movement along the slide rail as the door opens or closes. The side wall of the push rod is hinged to the slider via the hinge axis, enabling the end of the push rod located within the hinge box to automatically adjust its angle relative to the slider as it moves along the slide rail. This constrains the push rod's movement trajectory and prevents the push rod from jamming when the door opens or closes. Therefore, by setting up the slide rail, slider, and hinge axis, a constraint can be formed on the end of the push rod located within the hinge box, thereby preventing significant wobbling of the push rod inside the hinge box, reducing wear, and extending its service life. It also avoids noise caused by significant wobbling of the push rod and prevents wear on the power supply harness caused by such wobbling. Attached Figure Description

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0030] Please refer to Figures 1 to 5. This application provides a refrigerator power supply harness threading mechanism 100. The refrigerator power supply harness threading mechanism 100 includes a push rod 10, a hinge box 20, and a harness box 30. The hinge box 20 is used to install to the refrigerator body, and the harness box 30 is used to install to the door body. One end of the push rod 10 is movably located inside the hinge box 20, and the other end extends out of the hinge box 20 and is hinged to the harness box 30. The hinge box 20 is located at the top of the refrigerator body, and the harness box 30 is arranged parallel to the door body. The refrigerator power supply harness threading mechanism 100 also includes a slide rail 40, a slider 50, and a hinge shaft 60. The slide rail 40 is located inside the hinge box 20 and on one side of the push rod 10. The slider 50 is slidably connected to the slide rail 40. The side wall of the push rod 10 is hinged to the slider 50 through the hinge shaft 60. When the door is opened, the push rod 10 can rotate around the hinge shaft 60 and move out of the hinge box 20 along the slide rail 40. When the door is closed, the push rod 10 can rotate around the hinge shaft 60 and move inward into the hinge box along the slide rail 40.

[0031] Understandably, as the door opens or closes, the movement trajectory of the push rod 10 can be decomposed into rotation around the hinge axis 60 and movement along the slide rail 40. The side wall of the push rod 10 is hinged to the slider 50 via the hinge axis 60, allowing the end of the push rod 10 located within the hinge box 20 to automatically adjust its angle relative to the slider 50 as it moves along the slide rail 40. This constrains the movement trajectory of the push rod 10 and prevents it from jamming when the door opens or closes. Therefore, by setting up the slide rail 40, slider 50, and hinge axis 60, a constraint can be formed on the end of the push rod 10 located within the hinge box 20. This transforms the movement trajectory of the end of the push rod 10 within the hinge box 20 from irregular and unpredictable large swings into regular oscillations relative to the slide rail 40, thereby reducing wear on the push rod 10 and extending its service life. It also avoids motion noise caused by large-scale shaking of the push rod 10, and avoids wear and tear on the power supply harness caused by large-scale shaking of the push rod 10.

[0032] As shown in Figures 6 and 7, the push rod 10 has a first protrusion 11 on its side wall, and the slider 50 has a second protrusion 51 on its side wall. The first protrusion 11 and the second protrusion 51 are rotatably connected around the hinge shaft 60. It can be understood that the first protrusion 11 and the second protrusion 51 provide an installation position for the hinge shaft 60.

[0033] One end of the hinge shaft 60 is fixedly connected to one of the first protrusion 11 and the second protrusion 51. The other one of the first protrusion 11 and the second protrusion 51 has a locking hole 511. The other end of the hinge shaft 60 is movably inserted through the locking hole 511 and is elastically snapped into the locking hole 511.

[0034] In one embodiment, for example, one end of the hinge shaft 60 is fixedly connected to the first protrusion 11, the second protrusion 51 has a locking hole 511, and the other end of the hinge shaft 60 is movably inserted through the locking hole 511 and elastically snapped into place. This simplifies the connection structure between the push rod 10, the slider 50, and the hinge shaft 60, thereby facilitating their assembly.

[0035] Specifically, the hinge shaft 60 is located on the upper end face of the first protrusion 11 along its own thickness direction and is integrally formed with the first protrusion 11. The second protrusion 51 is stacked on the upper end face of the first protrusion 11 and is elastically snapped to the end of the hinge shaft 60 away from the first protrusion 11 through the snap hole 511.

[0036] Alternatively, in another embodiment, one end of the hinge shaft 60 may be fixedly connected to the second protrusion 51, the first protrusion 11 may have a locking hole 511, and the other end of the hinge shaft 60 may be movably inserted through the locking hole 511 and elastically snapped together with the locking hole 511.

[0037] The following section describes the specific structure of the hinge shaft 60, taking as an example the hinge shaft 60 being fixedly connected to the first protrusion 11 and the locking hole 511 being opened on the second protrusion 51.

[0038] As shown in Figure 7, the hinge shaft 60 includes multiple elastic retaining strips 61 spaced apart around its own axial direction, with a deformation gap 62 formed between adjacent elastic retaining strips 61. Each elastic retaining strip 61 has a first segment 611 and a second segment 612. The first segment 611 is fixedly connected to the first protrusion 11, and the cross-sectional area of ​​the hinge shaft 60 in the first segment 611 is smaller than the cross-sectional area of ​​the second segment 612. As the hinge shaft 60 is inserted into the retaining hole 511 from the end where the second segment 612 is located, the multiple elastic retaining strips 61 can move closer to each other in response to the compression of the inner wall of the retaining hole 511 until the second segment 612 passes through the retaining hole 511, at which point the elastic retaining strips 61 return to their original position and the second segment 612 stops at the outer periphery of the retaining hole 511.

[0039] It should be noted that the cross-sectional area of ​​the hinge shaft 60 in the first segment 611 is smaller than that in the second segment 612. This means that in its unloaded, natural state, the cross-sectional area of ​​the hinge shaft 60 in the first segment 611 is smaller than that in the second segment 612. Because a deformation gap 62 is formed between adjacent elastic retaining strips 61, as the hinge shaft 60 is inserted into the retaining hole 511 from the end containing the second segment 612, the multiple elastic retaining strips 61 can elastically deform in response to the compression of the inner wall of the retaining hole 511 and move closer together to facilitate the passage of the second segment 612 through the retaining hole 511. After the second segment 612 passes through the retaining hole 511, the elastic retaining strips 61 return to their original position, causing the second segment 612 to stop at the outer periphery of the retaining hole 511, thereby achieving an elastic snap-fit ​​connection between the end of the hinge shaft 60 away from the first protrusion 11 and the second protrusion 51 through the retaining hole 511.

[0040] Optionally, multiple elastic clips 61 are evenly spaced around the hinge axis 60.

[0041] For example, in one embodiment, the number of elastic clips 61 is configured to be 6, and the 6 elastic clips 61 are evenly spaced around the hinge axis 60. Of course, this is not the only possibility; in other embodiments, the number of elastic clips 61 may also be 3, 5, or 7, etc., which can be set according to actual needs.

[0042] Furthermore, in one embodiment, along the direction from the second segment 612 to the first segment 611, the cross-sectional area of ​​the hinge shaft 60 in the second segment 612 gradually increases and then gradually decreases. That is, along the axial direction of the hinge shaft 60, the cross-sectional area of ​​the hinge shaft 60 in the second segment 612 is distributed with smaller areas at both ends and a larger area in the middle. This facilitates the insertion of the hinge shaft 60 into the retaining hole 511 from the end where the second segment 612 is located, and also facilitates the removal of the hinge shaft 60 from the retaining hole 511 from the end where the second segment 612 is located.

[0043] The slide rail 40 extends along the front-to-back direction x of the refrigerator. The slide rail 40 and one side inner wall of the hinge box 20 are spaced apart and enclosed to form a receiving space 21. As the door opens or closes, the push rod 10 moves within the receiving space 21. Specifically, the slide rail 40 is configured as a protrusion on the inner wall of the hinge box 20.

[0044] As shown in Figure 7, the slider 50 has a slot 52, through which the slider 50 is slidably engaged with the upper end face of the slide rail 40 along the height direction z of the refrigerator. This facilitates the assembly between the slider 50 and the slide rail 40.

[0045] Optionally, in one embodiment, the upper surface of the slide rail 40 along the height direction z of the refrigerator is configured as an arc surface, and the slot 52 is configured as a U-shaped slot. This makes the mating surfaces of the slide rail 40 and the slot 52 smoother, thereby reducing the friction between the slider 50 and the slide rail 40, and allowing the end of the push rod 10 located inside the hinge box 20 to move more smoothly.

[0046] Optionally, in one embodiment, the slider 50 has a cavity 53, and slots 52 are formed on two side walls of the slider 50 along the front-rear direction x of the refrigerator, and the slots 52 communicate with the cavity 53. That is, the slider 50 is configured as a hollow structure, which helps to reduce the weight of the slider 50 and thus reduce the friction between the slider 50 and the slide rail 40. This allows the end of the push rod 10 located inside the hinge box 20 to move more smoothly.

[0047] This application also provides a refrigerator, which includes a cabinet, a door, a power supply harness, and a power supply harness threading mechanism 100 as described in any of the above embodiments. The power supply harness threading mechanism 100 includes a push rod 10, a hinge box 20, and a harness box 30. The hinge box 20 is installed to the cabinet, and the harness box 30 is installed to the door. One end of the push rod 10 is movably located inside the hinge box 20 and has a first hole 12. The other end extends out of the hinge box 20 and is hinged to the harness box 30. The end of the push rod 10 that is hinged to the harness box 30 has a second hole 13. The power supply harness passes through the hinge box 20, through the first hole 12, into the push rod 10, and through the second hole 13 out of the push rod 10. Then the power supply harness is connected to the harness box 30.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
