AI Technical Summary
In the existing refrigerator power supply harness threading mechanism, the movement trajectory of the push rod is unpredictable during the opening or closing of the door, resulting in significant shaking and noise, which in turn accelerates wear and affects service life.
The system employs a combination structure of a rocker arm, a first hinge axis, and a second hinge axis. The second hinge axis constrains the push rod, causing it to swing regularly around the first hinge axis, thus preventing jamming and reducing wobbling.
It effectively reduces wear on push rods and wiring harnesses, extends service life, reduces motion noise, and improves operational stability.

Abstract
Description
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. Utility Model Content
[0004] Therefore, it is necessary to provide a refrigerator power supply harness threading mechanism and a refrigerator to reduce the shaking of the push rod during the opening and closing of the door.
[0005] The refrigerator power supply harness threading mechanism includes a push rod, a hinge box, and a harness box. The hinge box is used to install to the refrigerator body, and the 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 harness box. The refrigerator power supply harness threading mechanism includes a rocker arm, a first hinge shaft, and a second hinge shaft. The rocker arm has a first end and a second end that are arranged opposite to each other. The first end is rotatably connected to the inner wall of the hinge box around the first hinge shaft, and the second end is rotatably connected to the end of the push rod that is movably located inside the hinge box around the second hinge shaft. As the door opens or closes, the end of the push rod that is movably located inside the hinge box can swing around the first hinge shaft via the second hinge shaft and the rocker arm.
[0006] In one embodiment, a first locking hole is provided at the first end, and a first hinge shaft is elastically fastened to the first locking hole; a second locking hole is provided at the second end, and a second hinge shaft is elastically fastened to the second locking hole.
[0007] In one embodiment, the first hinge shaft includes a plurality of first elastic retaining strips spaced apart around its own axial direction, with a first deformation gap formed between two adjacent first elastic retaining strips; each first elastic retaining strip has a first segment and a second segment connected axially along the first hinge shaft, the first segment being fixedly connected to the inner wall of the hinge box, and the cross-sectional area of the first hinge shaft in the first segment being smaller than the cross-sectional area in the second segment; and, as the first hinge shaft is inserted into the first retaining hole from the end where the second segment is located, the plurality of first elastic retaining strips can move closer to each other in response to the compression of the inner wall of the first retaining hole until the second segment passes through the first retaining hole, the first elastic retaining strips are reset and the second segment is stopped at the outer periphery of the first retaining hole.
[0008] In one embodiment, along the direction from the second segment to the first segment, the cross-sectional area of the first hinge shaft in the second segment gradually increases and then gradually decreases.
[0009] In one embodiment, the second hinge shaft includes a plurality of second elastic retaining strips spaced apart around its own axial direction, with a second deformation gap formed between two adjacent second elastic retaining strips; each second elastic retaining strip has a third segment and a fourth segment connected axially along the second hinge shaft, one end of the third segment is fixedly connected to the push rod, and the cross-sectional area of the second hinge shaft in the third segment is smaller than the cross-sectional area in the fourth segment; and, as the second hinge shaft is inserted into the second retaining hole from the end where the fourth segment is located, the plurality of second elastic retaining strips can move closer to each other in response to the compression of the inner wall of the second retaining hole until the fourth segment passes through the second retaining hole, the second elastic retaining strips are reset and the fourth segment stops at the outer periphery of the second retaining hole.
[0010] In one embodiment, along the direction from the fourth segment to the third segment, the cross-sectional area of the second hinge shaft in the fourth segment gradually increases and then gradually decreases.
[0011] In one embodiment, the push rod is located on the side wall of one end of the hinge box, which is provided with a mounting protrusion. One end of the second hinge shaft is fixedly connected to the mounting protrusion, and the other end is elastically connected to the second latching hole.
[0012] In one embodiment, the push rod, mounting protrusion, and second hinge shaft are configured as a single unit.
[0013] In one embodiment, the first hinge shaft and the hinge box are configured as an integral structure; or, the first hinge shaft is detachably connected to the inner wall of the hinge box.
[0014] A refrigerator includes a cabinet, a door, 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, as the door opens, the end of the push rod hinged to the harness box moves away from the hinge box, and the end of the push rod inside the hinge box rotates around the first hinge axis toward the outside of the hinge box; as the door closes, the end of the push rod hinged to the harness box moves toward the hinge box, and the end of the push rod inside the hinge box rotates around the first hinge axis toward the inside of the hinge box. The inclusion of a second hinge axis prevents jamming between the rocker arm and the push rod when the end of the push rod inside the hinge box rotates relative to the first hinge axis. Therefore, by providing a rocker arm, a first hinge axis, and a second hinge axis, a constraint is formed on the end of the push rod inside the hinge box, changing its movement trajectory from irregular and uncontrollable large-amplitude swaying to a regular oscillation relative to the first hinge axis, thereby reducing push rod wear and extending its service life. It also avoids motion noise caused by large-scale shaking of the push rod, and avoids wear and tear on the power supply harness caused by large-scale shaking of the push rod.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.
[0029] Please see Figures 1 to 4 This application provides a refrigerator power supply harness threading mechanism 100, which includes a push rod 10, a hinge box 20, and a harness box 30. The hinge box 20 is used to install onto the refrigerator body, specifically, the hinge box 20 is installed on the top of the refrigerator body. The harness box 30 is used to install onto the door body, specifically, the harness box 30 is arranged parallel 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 refrigerator power supply harness threading mechanism includes a rocker arm 40, a first hinge shaft 50, and a second hinge shaft 60. The rocker arm 40 has a first end 41 and a second end 42 that are arranged opposite to each other. The first end 41 is rotatably connected to the inner wall of the hinge box 20 around the first hinge shaft 50, and the second end 42 is rotatably connected to one end of the push rod 10 that is movably located inside the hinge box 20 around the second hinge shaft 60. As the door opens or closes, the end of the push rod 10 that is movably located inside the hinge box 20 can swing around the first hinge shaft 50 via the second hinge shaft 60 and the rocker arm 40.
[0030] Understandably, as the door opens, the end of the push rod 10 hinged to the wire harness box 30 moves away from the hinge box 20, and the end of the push rod 10 inside the hinge box 20 rotates around the first hinge axis 50 toward the outside of the hinge box 20. As the door closes, the end of the push rod 10 hinged to the wire harness box 30 moves toward the hinge box 20, and the end of the push rod 10 inside the hinge box 20 rotates around the first hinge axis 50 toward the inside of the hinge box 20. The second hinge axis 60 prevents the rocker arm 40 from jamming with the push rod 10 when the end of the push rod 10 inside the hinge box 20 rotates around the first hinge axis 50. Therefore, by setting the rocker arm 40, the first hinge axis 50, and the second hinge axis 60, a constraint can be formed on the end of the push rod 10 located within the hinge box 20. This changes the movement trajectory of the end of the push rod 10 within the hinge box 20 from irregular and uncontrollable large-amplitude swaying to regular oscillation relative to the first hinge axis 50. This helps reduce wear on the push rod 10 and extend its service life. It also avoids motion noise caused by large-amplitude swaying of the push rod 10, and prevents wear on the power supply harness caused by large-amplitude swaying of the push rod 10.
[0031] like Figure 5 and Figure 6 As shown, the first end 41 has a first locking hole 411, and the first hinge shaft 50 is elastically connected to the first locking hole 411; the second end 42 has a second locking hole 421, and the second hinge shaft 60 is elastically connected to the second locking hole 421. This design simplifies the structure of the rocker arm 40 and facilitates its manufacturing. Furthermore, it facilitates the assembly of the rocker arm 40 with the first hinge shaft 50 and the second hinge shaft 60.
[0032] In one embodiment, the first hinge shaft 50 includes a plurality of first elastic retaining strips 51 spaced apart around its own axial direction, with a first deformation gap 52 formed between two adjacent first elastic retaining strips 51; each first elastic retaining strip 51 has a first segment 511 and a second segment 512 connected axially along the first hinge shaft 50, the first segment 511 is fixedly connected to the inner wall of the hinge box 20, and the cross-sectional area of the first hinge shaft 50 in the first segment 511 is smaller than the cross-sectional area of the second segment 512; and as the first hinge shaft 50 is inserted into the first retaining hole 411 from the end where the second segment 512 is located, the plurality of first elastic retaining strips 51 can move closer to each other in response to the compression of the inner wall of the first retaining hole 411 until the second segment 512 passes through the first retaining hole 411, the first elastic retaining strips 51 are reset and the second segment 512 is stopped at the outer periphery of the first retaining hole 411.
[0033] It should be noted that the cross-sectional area of the first hinge shaft 50 in the first segment 511 is smaller than that in the second segment 512. This means that in its natural, unforced state, the cross-sectional area of the first hinge shaft 50 in the first segment 511 is smaller than that in the second segment 512. Because a first deformation gap 52 is formed between two adjacent first elastic locking strips 51, as the first hinge shaft 50 is inserted into the first locking hole 411 from the end containing the second segment 512, the multiple first elastic locking strips 51 can respond to the compression of the inner wall of the first locking hole 411 and compress the first deformation gap 52, thus bringing them closer together to facilitate the passage of the second segment 512 through the first locking hole 411. After the second segment 512 passes through the first locking hole 411, the first elastic locking strips 51 return to their original position, causing the second segment 512 to stop at the outer periphery of the first locking hole 411. This achieves an elastic snap-fit connection between the first hinge shaft 50 and the first locking hole 411.
[0034] Optionally, multiple first elastic retaining strips 51 are evenly spaced around the axis of the first hinge shaft 50. This makes the deformation of the first hinge shaft 50 more uniform at all positions along its circumference. The number of first elastic retaining strips 51 can be configured as 3, 4, 5, or 6, etc., and can be set according to actual needs, which will not be listed here.
[0035] Furthermore, in one embodiment, along the direction from the second segment 512 to the first segment 511, the cross-sectional area of the first hinge shaft 50 in the second segment 512 gradually increases and then gradually decreases. That is, in this embodiment, along the axial direction of the first hinge shaft 50, the cross-sectional area of the first hinge shaft 50 in the second segment 512 is distributed with smaller areas at both ends and a larger area in the middle. This facilitates the insertion of the first hinge shaft 50 into the first locking hole 411 from the end of the second segment 512, and also facilitates the removal of the first hinge shaft 50 from the first locking hole 411 from the end of the second segment 512.
[0036] Furthermore, the first hinge shaft 50 also includes a mounting base 53, and a plurality of first elastic retaining strips 51 are respectively connected to the mounting base 53 and mounted on the inner wall of the hinge box 20 through the mounting base 53. In addition, the cross-sectional area of the first hinge shaft 50 at the mounting base 53 is larger than the cross-sectional area of the first segment 511.
[0037] Optionally, in one embodiment, the first hinge shaft 50 and the hinge box 20 are configured as an integral structure. Alternatively, in another embodiment, the first hinge shaft 50 may also be detachably connected to the inner wall of the hinge box 20.
[0038] In one embodiment, the second hinge shaft 60 includes a plurality of second elastic retaining strips 61 spaced apart around its own axial direction, with a second deformation gap 62 formed between two adjacent second elastic retaining strips 61; each second elastic retaining strip 61 has a third segment 611 and a fourth segment 612 connected axially along the second hinge shaft 60, one end of the third segment 611 is fixedly connected to the push rod 10, and the cross-sectional area of the second hinge shaft 60 in the third segment 611 is smaller than the cross-sectional area in the fourth segment 612; and as the second hinge shaft 60 is inserted into the second retaining hole 421 from the end where the fourth segment 612 is located, the plurality of second elastic retaining strips 61 can move closer to each other in response to the compression of the inner wall of the second retaining hole 421 until the fourth segment 612 passes through the second retaining hole 421, the second elastic retaining strips 61 are reset and the fourth segment 612 stops at the outer periphery of the second retaining hole 421.
[0039] Similarly, it should be noted that the cross-sectional area of the second hinge shaft 60 in the third segment 611 is smaller than that in the fourth segment 612. This means that, in its natural, unforced state, the cross-sectional area of the second hinge shaft 60 in the third segment 611 is smaller than that in the fourth segment 612. Since a second deformation gap 62 is formed between two adjacent second elastic retaining strips 61, as the second hinge shaft 60 is inserted into the second retaining hole 421 from the end containing the fourth segment 612, the multiple second elastic retaining strips 61 can respond to the compression of the inner wall of the second retaining hole 421 and compress the second deformation gap 62, thus bringing them closer together to facilitate the passage of the fourth segment 612 through the second retaining hole 421. After the fourth segment 612 passes through the second retaining hole 421, the second elastic retaining strips 61 return to their original position, causing the fourth segment 612 to stop at the outer periphery of the second retaining hole 421. In this way, the second hinge shaft 60 and the second retaining hole 421 are elastically snapped together.
[0040] Optionally, multiple second elastic retaining strips 61 are evenly spaced around the axis of the second hinge shaft 60. This makes the deformation of the second hinge shaft 60 more uniform at all positions along its circumference. The number of second elastic retaining strips 61 can be configured as 3, 4, 5, or 6, etc., depending on actual needs, and will not be listed here.
[0041] Furthermore, in one embodiment, along the direction from the fourth segment 612 to the third segment 611, the cross-sectional area of the second hinge shaft 60 at the fourth segment 612 gradually increases and then gradually decreases. That is, in this embodiment, along the axial direction of the second hinge shaft 60, the cross-sectional area of the second hinge shaft 60 at the fourth segment 612 is distributed with smaller areas at both ends and a larger area in the middle. This facilitates the insertion of the second hinge shaft 60 into the second locking hole 421 from the end where the fourth segment 612 is located, and also facilitates the removal of the second hinge shaft 60 from the second locking hole 421 from the end where the fourth segment 612 is located.
[0042] Optionally, in one embodiment, the push rod 10 is movably located on the side wall of one end inside the hinge box 20, and a mounting protrusion 11 is provided. One end of the second hinge shaft 60 is fixedly connected to the mounting protrusion 11, and the other end is elastically snapped to the second latch hole 421.
[0043] Alternatively, in one embodiment, the push rod 10, the mounting protrusion 11, and the second hinge shaft 60 are configured as a single unit.
[0044] This application also provides a refrigerator, which 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 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.
[0045] 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.
[0046] 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.
