[0058] The specific embodiments of this application will be further described below with reference to the accompanying drawings.

[0059] It is readily understood that, based on the technical solution of this application, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of this application. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this application and should not be considered as the entirety of this application or as limitations or restrictions on the technical solution of the application.

[0060] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0061] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meanings of the above in this application according to the specific circumstances.

[0062] The wiring harness structure of the electronic window glass in this embodiment of the application is as follows: Figure 1 As shown, it includes a slide rail 02 mounted on the inner door panel 01 and a window glass 03 slidably mounted on the slide rail 02, and also includes a wire harness winding assembly 04 mounted on the inner door panel 01 and a wire harness 05 at least partially wound in the wire harness winding assembly 04.

[0063] The wire harness 05 includes a fixed end and a sliding end. The fixed end is fixed to the wire harness winding assembly 04, and the sliding end is connected to the window glass 03 and slides along the slide rail with the window glass 03.

[0064] The wire harness winding assembly 04 is installed on the inner panel 01 of the door and located on one side of the slide rail 02. The wire harness winding assembly 04 is provided with a wire winding energy storage component 41, which provides a tightening force to the wire harness 05 so that the wire harness 05 has a tendency to tighten into the wire harness winding assembly 04.

[0065] Regarding the installation structure of the window glass 03, a slide rail 02 is installed on the side of the inner door panel 01 facing the inside of the vehicle. The window glass 03 is slidably installed on the slide rail 02. The window glass 03 is raised and lowered by controlling the window glass 03 to slide along the slide rail 02. For the installation structure of the slide rail 02 and the window glass 03, please refer to the relevant structure of the existing technology, which will not be described in detail here.

[0066] In this embodiment, the vehicle window glass 03 is made of electronic glass, which may have functions such as dimming and / or color adjustment and / or display. The sliding end of the wiring harness 05 is connected to the lower end of the vehicle window glass 03, and the fixed end is fixedly connected to the wiring harness winding assembly 04. The sliding end is electrically connected to the vehicle window glass 03, and the fixed end leads out a connector from the wiring harness winding assembly 04. The control unit is electrically connected to the connector to realize the electronic control of the vehicle window glass 03 through the wiring harness.

[0067] The wire harness winding assembly 04 is located on one side of the slide rail 02, and includes a winding energy storage element 41 to provide force for tightening the wire harness 05. For example... Figure 3 As shown, during the sliding process of the window glass 03, the sliding end of the wiring harness 05 also slides between the highest point A and the lowest point B. When the sliding end of the wiring harness 05 is at the highest point A, the wiring harness trajectory of the wiring harness retraction assembly 04 is FA; when the sliding end of the wiring harness 05 is at the lowest point B, the wiring harness trajectory of the wiring harness retraction assembly 04 is FB. Clearly, the length of the wiring harness in the wiring harness retraction assembly 04 is different when the window glass 03 slides to different positions. The wire harness energy storage component 41 gives the wiring harness 05 a tendency to tighten into the wiring harness retraction assembly 04, enabling it to retract excess wire harness length in real time. This ensures that the wiring harness 05 between the wiring harness retraction assembly 04 and the window glass 03 remains taut during the sliding process of the window glass 03, constraining the wiring harness 05 and preventing it from becoming loose and interfering with or tangling with other components. Preferably, the installation height of the wire harness winding assembly 04 is located between the height of the highest point A and the height of the lowest point B, which can effectively shorten the required length of the wire harness 05.

[0068] It should be noted that because both the inner door panel 01 and the window glass 03 have a certain degree of curvature in the vertical direction, the sliding trajectory of the sliding end of the wiring harness 05 is also curved. That is, the sliding end of the wiring harness 05 will deviate in the inward and outward directions of the door during the sliding process, such as... Figure 2 As shown, the sliding trajectory of the sliding end of wire harness 05 is ⌒AB.

[0069] In a preferred embodiment, data processing determines that the installation position and dimensions of the wire harness retraction assembly 04 are limited as follows to minimize the offset of the wire harness in the inward and outward directions of the vehicle door, while also minimizing the extension of the wire harness:

[0070] Regarding the installation location of the wire harness retraction assembly 04, as follows: Figure 2 As shown, the sliding trajectory of the sliding end of the wire harness 05 is as follows: draw line segment AB between ⌒AB, determine the midpoint J of ⌒AB and the midpoint K of line segment AB, draw a first plane parallel to the center plane of the wire harness winding assembly 04 through midpoint J, draw a second plane parallel to the center plane of the wire harness winding assembly 04 through midpoint K, and the center plane of the wire harness winding assembly 04 is located between the first and second planes. The center plane of the wire harness winding assembly 04 is a plane passing through the midpoint of the axial direction of the wire harness winding assembly 04 and perpendicular to the axial direction of the wire harness winding assembly 04. Preferably, the center plane of the wire harness winding assembly 04 is located on a third plane passing through the midpoint C of line segment JK and parallel to the inner door panel 01. Simultaneously, draw the normal plane of line segment AB through point K. The vertical distance between the center point of the wire harness winding assembly 04 and this normal plane is less than or equal to 100mm. The center point of the wire harness winding assembly 04 is the center position of one circle of wire harness 05 when the wire harness 05 is wound in the wire harness winding assembly 04.

[0071] Regarding the dimensions of the wire harness winding assembly 04, when the wire harness 05 is wound around the wire harness winding assembly 04, the diameter of the innermost wire harness 05 is 30mm-200mm.

[0072] In one embodiment, such as Figure 4 , 5 As shown, the wire harness retraction assembly 04 is mounted on the inner door panel 01 via the hinge assembly 06;

[0073] The hinge assembly 06 includes a fixed hinge arm 61, a rotating hinge arm 62, and a hinge shaft 63. The fixed hinge arm 61 is fixedly mounted on the inner panel 01 of the door. The rotating hinge arm 62 is rotatably mounted on the fixed hinge arm 61 via the hinge shaft 63. The hinge shaft 63 is arranged parallel to the center plane of the wire harness winding assembly 04. The wire harness winding assembly 04 is mounted on the rotating hinge arm 62. The center plane of the wire harness winding assembly 04 is a plane that passes through the axial midpoint of the wire harness winding assembly 04 and is perpendicular to the axial direction of the wire harness winding assembly 04.

[0074] In this embodiment, the wire harness winding assembly 04 is mounted on the inner panel 01 of the vehicle door via a hinge assembly 06. The hinge pivot 63 is arranged parallel to the center surface of the wire harness winding assembly 04, allowing the wire harness winding assembly 04 to rotate in the inward and outward directions of the vehicle door. This compensates for the offset of the wire harness 05 in the inward and outward directions of the vehicle door, preventing the wire harness 05 from frequently twisting and causing the wire harness sheath or core to break or be damaged, thus affecting the normal use of the vehicle window glass 03.

[0075] In a preferred embodiment, the arrangement of the hinge pivot 63 is restricted in the following way to achieve the best sway compensation effect for the wire harness take-up assembly 04:

[0076] like Figure 3 As shown, when the sliding end of wire harness 05 slides to the highest point A, the point of tangency between the extended portion of wire harness 05 and the wire harness winding assembly 04 is point E, and wire harness 05 extends along the EA direction; when the sliding end of wire harness 05 slides to the lowest point B, the point of tangency between the extended portion of wire harness 05 and the wire harness winding assembly 04 is point F, and wire harness 05 extends along the FB direction. Draw a straight line EI parallel to FB through point E, and then draw the angle bisector ED of ∠AEI. The axial direction of the hinge pivot 63 is set parallel to EG, so that ∠DEG is 45°-135°, with 90° being optimal.

[0077] In one embodiment, the hinge assembly 06 further includes a reset member 64, which includes a column 641 disposed on the fixed hinge arm 61, a rotating rod 642 connected between the rotating hinge arm 62 and the fixed hinge arm 61, and a first reset spring 643 and a second reset spring 644 mounted on the rotating rod 642.

[0078] One end of the rotating rod 642 is rotatably mounted on the rotating hinge arm 62 via a reset shaft 645, which is parallel to the hinge shaft 63.

[0079] The other end of the rotating rod 642 passes through the column 641. The rotating rod 642 is provided with a first limiting ring 6421 and a second limiting ring 6422. The first limiting ring 6421 and the second limiting ring 6422 are located on both sides of the column 641, respectively. The first return spring 643 abuts between the first limiting ring 6421 and the column 641, and the second return spring 644 abuts between the second limiting ring 6422 and the column 641.

[0080] Specifically, the column 641 is rotatably mounted on the fixed hinge arm 61. The column 641 has a through hole, through which the rotating rod 642 passes and is connected to the column 641. The column 641 and the rotating rod 642 are perpendicular to each other. As the rotating hinge arm 62 rotates relative to the fixed hinge arm 61, it causes the rotating rod 642 to slide along the through hole. When the wire harness winding assembly 04 rotates towards the inner door panel 01, the first return spring 643 is compressed. When the rotational force of the wire harness winding assembly 04 is removed, the wire harness winding assembly 04 can return to its original position under the elastic force of the first return spring 643. When the wire harness winding assembly 04 rotates away from the inner door panel 01, the second return spring 644 is compressed. When the rotational force of the wire harness winding assembly 04 is removed, the wire harness winding assembly 04 can return to its original position under the elastic force of the second return spring 644.

[0081] This embodiment of the application provides a reset component 64, which enables the wire harness winding assembly 04 to quickly reset after each deflection compensation, thereby ensuring that the wire harness winding assembly 04 is always at a preset angle and avoiding bending and twisting of the wire harness 05.

[0082] In one embodiment, such as Figure 7 , 8 As shown, the vehicle window glass 03 is provided with a wiring port 31 and a mounting bracket 32. The sliding end of the wiring harness 05 is fixed on the mounting bracket 32 ​​and connected to the wiring port 31 through the plug 51.

[0083] The wire harness 05 is also provided with a connecting part 52, which is rotatably connected to the mounting bracket 32 ​​via the bracket pivot 53.

[0084] Specifically, the window glass 03 has a wiring port 31 for connecting electrical signals and power. A mounting bracket 32 ​​supports the sliding end of the wiring harness 05. The mounting bracket 32 ​​is positioned below the wiring port 31 and extends towards the interior of the vehicle to avoid interference with the door inner panel 01 during window operation. The sliding end of the wiring harness 05 is connected to a connector 51, which in turn connects to the wiring port 31. The wiring port 31 is secured with sealant, and the connector 51 is waterproof to prevent water ingress and short circuits at the connection point.

[0085] The connecting part 52 on the wiring harness 05 is connected to the mounting bracket 32. The bracket pivot 53 is arranged parallel to the center plane of the wiring harness winding assembly 04, preferably parallel to the hinge pivot 63. During the sliding process of the sliding end of the wiring harness 05, the connecting part 52 can rotate around the hinge pivot 63 to further compensate for the offset of the wiring harness 05 in the direction of the inside and outside of the door.

[0086] The connecting part 52 is made of rubber material and has a through hole. A bushing 521 is installed in the through hole. The bracket shaft 53 is installed through the bushing 521 to avoid wear caused by friction between the rubber material and the metal bracket shaft 53, and also to reduce the rotational friction of the connecting part 52.

[0087] In one embodiment, such as Figure 8 , 9 As shown, the wire harness 05 includes a wire harness core 54 and / or a steel wire 55; the end of the connecting part 52 away from the sliding end is provided with a hollow support part 522, which covers the wire harness core 54 and / or the steel wire 55.

[0088] like Figure 9 As shown, the wire harness 05 includes at least two wire harness cores 54. In order to improve the rigidity of the wire harness 05, a steel wire 55 can also be provided. The steel wire 55 is located between the two wire harness cores 54. In other areas outside the connection part 52, the wire harness cores 54 and the steel wire 55 are covered by an insulating wire harness sheath.

[0089] like Figure 8 As shown, the connecting part 52 is made of rubber material to injection mold the wire harness core 54, steel wire 55 and bushing 521 into one piece. The end of the connecting part 52 away from the sliding end is provided with a hollow support part 522. The hollow support part 522 can completely cover the wire harness core 54 to achieve an insulation effect. It has a support area and a hollow area. The thickness of the hollow area is less than the thickness of the support area, thereby improving the flexibility of the hollow support part 522, realizing the transition of the connecting part 52, and reducing the risk of breakage when the connecting part 52 rotates around the bracket pivot 53.

[0090] In one embodiment, such as Figure 9 , 10 As shown, the wire harness winding assembly 04 is provided with a circumferential winding groove 421, and at least a portion of the wire harness 05 is wound on the circumferential winding groove 421. The bottom of the circumferential winding groove 421 is provided with a first limiting groove 4211.

[0091] The first surface of the wire harness 05 is provided with a limiting protrusion 56, which is arranged along the length direction of the wire harness 05. Part of the limiting protrusion 56 is fitted into the first limiting groove 4211 to limit the wire harness 05.

[0092] Specifically, the cross-section of the wire harness 05 is waist-shaped, and a limiting protrusion 56 is provided on the first side facing the circumferential winding groove 421. The limiting protrusion 56 is fitted into the first limiting groove 4211 to position the wire harness 05 in the circumferential winding groove 421, so that the wire harness 05 is stably wound in the circumferential winding groove 421.

[0093] In one embodiment, such as Figure 9 , 10As shown, a second limiting groove 57 is provided on the second surface of the wire harness 05. The second surface is opposite to the first surface, and the second limiting groove 57 is arranged along the length direction of the wire harness 05.

[0094] When the wire harness 05 is wound in at least two layers in the circumferential winding groove 421, the outer limiting protrusion 56 engages with the inner second limiting groove 57 to limit the wire harness 05.

[0095] Specifically, a second limiting groove 57 is provided on the second surface of the wire harness 05. The concave direction of the second limiting groove 57 is the same as the convex direction of the limiting protrusion 56, and the groove shape of the second limiting groove 57 matches the shape of the limiting protrusion 56. When the circumferential winding groove 421 winds up at least two layers of wire harness 05, the limiting protrusion 56 of the innermost wire harness engages in the first limiting groove 4211, and the limiting protrusion 56 of the outer wire harness engages in the second limiting groove 57 of the inner wire harness. This not only ensures that the wire harness 05 is stably wound in the wire harness winding assembly 04, but also ensures that the wire harness 05 automatically returns to its original position during the winding process, preventing the wire harness 05 from twisting.

[0096] Preferably, a drag-reducing coating can be applied to the surface of the wire harness 05 to reduce the resistance of the wire harness 05 during take-up and take-down, making the take-up and take-down of the wire harness 05 smoother.

[0097] In one embodiment, such as Figure 4 , 11 As shown, a wire harness guide assembly 07 is installed on the wire harness winding assembly 04. The wire harness guide assembly 07 includes a guide rod 71, a guide ring 72, a first guide shaft 73, and a second guide shaft 74.

[0098] One end of the guide rod 71 is rotatably mounted on the wire harness winding assembly 04 via the first guide shaft 73, and the other end is rotatably connected to the guide ring 72 via the second guide shaft 74. The first guide shaft 73 is parallel to the second guide shaft 74. The sliding end of the wire harness 05 passes through the guide ring 72 and is connected to the window glass 03. The inner surface of the guide ring 72 is in contact with the outer surface of the wire harness 05.

[0099] Specifically, the guide ring 72 is waist-shaped and can be slidably fitted onto the wire harness 05 to guide the winding of the wire harness 05 and prevent the wire harness 05 from twisting during the winding process. For example... Figure 11 As shown, a guide bracket 75 can be provided, a guide ring 72 is fixed on the guide bracket 75, and a guide rod 71 is rotatably connected to the guide bracket 75 via a second guide shaft 74. The first guide shaft 73 and the second guide shaft 74 are arranged parallel to the axial direction of the wire harness take-up assembly 04.

[0100] In this embodiment of the application, a wire harness guide component 07 is provided. When the window glass 03 drives the sliding end of the wire harness 05 to slide, the wire harness 05 drives the guide ring 72 to move, which in turn drives the guide rod 71 to rotate around the first guide shaft 73. During the rotation, the guide ring 72 always remains in contact with the outer surface of the wire harness 05 to guide the winding of the wire harness 05 and prevent the wire harness 05 from twisting.

[0101] In one embodiment, such as Figure 12 As shown, the wire harness winding assembly 04 also includes a housing and a rotating disk 42 rotatably mounted in the housing. The wire harness 05 is wound onto the rotating disk 42, and the winding energy storage unit 41 is connected between the housing and the rotating disk 42.

[0102] Specifically, the housing is provided with a rotating shaft 431, and the rotating disk 42 is circular with a shaft hole 422 at its center. The shaft hole 422 is installed on the rotating shaft 431, so that the rotating disk 42 can rotate around the rotating shaft 431. The aforementioned circumferential winding groove 421 is provided on the outer circumferential wall of the rotating disk 42, and the winding of the wire harness 05 is realized by the rotation of the rotating disk 42.

[0103] The take-up energy storage unit 41 uses a helical spring. One end of the helical spring is connected to the rotating disk 42, and the other end is connected to the housing. During installation, the helical spring is in a pre-tightened state so that it provides a tightening force for the wire harness.

[0104] In one embodiment, such as Figure 12-15 As shown, the housing includes an inner shell 43 and an outer shell 44, with a rotating disk 42 installed between the inner shell 43 and the outer shell 44;

[0105] The inner shell 43 has two concentric conductive rings 432, and the outer surface of the inner shell 43 is equipped with two first electrical connectors 433, which are respectively connected to the two conductive rings 432.

[0106] The rotating disk 42 is provided with a receiving cavity 423, and a conductive ring 432 is installed in the receiving cavity 423. Two conductive springs 424 are provided in the receiving cavity 423, and each conductive spring 424 abuts against a conductive ring 432.

[0107] Two second electrical connectors 425 are installed on the side of the rotating disk 42 facing the outer casing 44 and are respectively connected to two conductive springs 424. The two wire harness cores 54 at the fixed end of the wire harness 05 are respectively connected to the two second electrical connectors 425.

[0108] The inner shell 43 and the outer shell 44 are connected to form a housing for mounting the rotating disk 42, on which the wire harness 05 is wound up. In this embodiment, a second electrical contact 425 and a conductive spring 424 are provided in the rotating disk 42 to electrically connect with the wire harness core 54. At the same time, two conductive rings 432 are provided in the inner shell 43 to abut against the conductive spring 424. The conductive rings 432 extend out of the outer shell 44 through the first electrical contact 433, thereby realizing the electrical connection of the wire harness 05.

[0109] Specifically, since the window glass 03 needs to block rainwater, rainwater will be carried into the inner door panel 01 during the raising and lowering process. Rainwater may also flow along the wiring harness 05 into the wiring harness retraction assembly 04. For this reason, a receiving cavity 423 is provided in the rotating disk 42 (see Figure 14 , 15 The conductive spring 424 is installed in the receiving cavity 423 to prevent water from getting into the connection between the conductive spring 424 and the conductive ring 432 and causing leakage. At the same time, a sealing ring is also provided at the connection between the inner shell 43 and the outer shell 44 to serve as a waterproof measure.

[0110] like Figure 13-15 As shown, two second electrical connectors 425 are provided on the side of the rotating disk 42 facing the outer casing 44. The two wire harness cores 54 at the fixed end of the wire harness 05 pass through the bottom of the circumferential winding groove 421 and are respectively welded to the two second electrical connectors 425. The two electrical connectors 425 are respectively electrically connected to two conductive springs 424 in the accommodating cavity 423.

[0111] The inner shell 43 has two protruding rings, and a conductive ring 432 is installed on the outer peripheral wall of each protruding ring. The receiving cavity 423 of the rotating disk 42 faces the inner shell 43. Conductive springs 424 are installed in the rotating disk 42, and each conductive spring 424 abuts against a conductive ring 432. As the rotating disk 42 rotates, the conductive springs 424 can always maintain contact with the conductive rings 432. Figure 15 As shown, the conductive spring 424 is spiral-shaped, which gives the conductive spring 424 a tendency to pop out to one side of the conductive ring 423, so as to ensure good contact between the conductive spring 424 and the guide ring 423.

[0112] like Figure 15 As shown, two first electrical connectors 433 are installed on the outer surface of the inner shell 43 and are respectively connected to two conductive rings 432. The conductive rings 432 are connected to conductive springs 424. The conductive springs 424 are connected to the wire harness core 54 through the second electrical connector 425. Therefore, by connecting an electrical signal to the two first electrical connectors 433, the vehicle window glass 05 can be powered and controlled through the wire harness 05.

[0113] In one embodiment, such as Figure 12 , 14As shown in Figure 15, the edge of the accommodating cavity 423 is provided with a retaining ring 426 protruding towards the inner shell 43. The side of the inner shell 43 facing the rotating disk 42 is provided with a sealing groove 434. A sealing ring 435 is provided in the sealing groove 434. The retaining ring 426 is installed into the sealing groove 434 and abuts against the sealing ring 435.

[0114] Specifically, a sealing ring 435 can be formed by injection molding rubber directly into the sealing groove 434, and a retaining ring 426 can be directly installed into the sealing groove 434 to completely seal the accommodating cavity 423, preventing moisture from entering the accommodating cavity 423 and achieving a better waterproof effect.

[0115] In one embodiment, such as Figure 12 As shown, the wire harness rewind assembly 04 also includes a first adapter 45;

[0116] The rotating disk 42 is provided with a support boss 427 and at least two positioning posts 428 on the side facing the outer shell 44. The protrusion height of the positioning posts 428 is higher than the protrusion height of the support boss 427.

[0117] The first adapter 45 is installed on the support boss 427. The first adapter 45 is provided with a positioning hole 451. The positioning pin 428 is inserted into the positioning hole 451 to position the first adapter 45.

[0118] One end of the retractable energy storage unit 41 is connected to the first adapter 45, and the other end is connected to the outer casing 44.

[0119] Specifically, at least two pairs of positioning holes 451 and positioning posts 428 are provided. The first adapter 45 cooperates with the positioning posts 428 on the rotating disk 42 through the positioning holes 451, so that the first adapter 45 and the rotating disk 42 remain relatively stationary and can rotate synchronously.

[0120] like Figure 13 As shown, the first adapter 45 is also provided with a support boss 427, which is used to support the first adapter 45 to prevent interference between the first adapter 45 and the wire harness core 54. The protrusion height of the positioning post 428 is higher than the protrusion height of the support boss 427. In this embodiment, the positioning post 428 protrudes from the support boss 427.

[0121] like Figure 12As shown, a second adapter 46 can be connected to the outer shell 44, with the second adapter 46 and the outer shell 44 remaining relatively stationary. One end of the take-up energy storage unit 41 is connected to the first adapter 45, and the other end is connected to the second adapter 46. The second adapter 46 and the outer shell 44 can be used to guide and install the take-up energy storage unit 41. When the take-up energy storage unit 41 undergoes certain deformation or displacement, resulting in insufficient rewinding force of the wire harness winding assembly 04, the outer shell 44 and the second adapter 46 can be removed. By simultaneously rotating the second adapter 46 and the outer shell 44, or by rotating the second adapter 46 relative to the outer shell 44, the take-up energy storage unit 41 can be driven to contract and recharge. When the tightening force of the take-up energy storage unit 41 meets the requirements, the outer shell 44 and the inner shell 43 can be reconnected, thus easily restoring the optimal tightening force of the wire harness winding assembly 04.

[0122] In one embodiment, such as Figure 4 , 12 As shown, an arc-shaped wire harness outlet 47 is provided on the outer circumferential surface of the housing. The arc-shaped wire harness outlet 47 is positioned facing the slide rail 02, and the sliding end of the wire harness 05 extends out from the lower end of the arc-shaped wire harness outlet 47.

[0123] Specifically, the arc-shaped wire harness outlet 47 is located on the side facing the slide rail 02, and is at least partially below the horizontal line where the center point of the wire harness winding assembly 04 is located, to prevent rainwater from entering the wire harness winding assembly 04 from the arc-shaped wire harness outlet 47. Furthermore, the sliding end of the wire harness 05 extends from the lower end of the arc-shaped wire harness outlet 47, as shown below. Figure 1 As shown, when the sliding end of the wire harness 05 is higher than the wire harness winding assembly 04, water will flow along the wire harness 05 to the wire harness winding assembly 04. By setting the wire harness 05 to extend from the lower end of the arc-shaped wire harness outlet 47, water can be guided to the bottom of the wire harness winding assembly 04, preventing water from flowing into the wire harness winding assembly 04 and further improving the waterproof effect.

[0124] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0125] The above description is merely the principle and preferred embodiment of this application. It should be noted that for those skilled in the art, implementation methods obtained by appropriately combining the technical solutions disclosed in different embodiments are also included within the technical scope of this invention. Based on the principle of this application, several other modifications can also be made, which should also be considered within the protection scope of this application.
