Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology, and relates to wiring harness brackets, specifically to a wiring harness bracket for wiring automotive folding seats. Background Technology

[0002] The existing wiring harness layout for car folding seats runs the wiring from the back of the seat. This wiring method requires a large amount of slack for the wiring harness when the backrest is folded all the way forward, and the wiring harness is exposed behind the seat. When the seat is returned to its normal position, there will be a pile of wiring harness, which requires the use of a cover to cover it, affecting the appearance. At the same time, when the backrest moves, the wiring harness will rub against the surrounding frame, which poses a risk of damage to the wiring harness. Summary of the Invention

[0003] In view of the above-mentioned technical problems and shortcomings, the purpose of this utility model is to provide a wiring harness bracket for automotive folding seat wiring. The wiring harness bracket is set on the side of the seat back frame, and the wires run from the side of the seat. At the same time, the lower edge of the wiring harness bracket is flush with the center of the backrest pivot. This design allows the wiring harness to rotate around the backrest pivot through the wiring harness bracket, reducing the movement trajectory, reducing the wiring harness movement margin, and solving problems such as wiring harness accumulation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A wiring harness bracket for wiring a car folding seat is provided. The wiring harness bracket is fixed to the side of the seat back frame, and the lower edge of the wiring harness bracket is flush with the center of the backrest pivot. The wiring harness bracket includes a bottom shell and a top cover. After the bottom shell and the top cover are assembled, a cavity for the wiring harness to pass through is formed between the bottom shell and the top cover. The wiring harness is led out from the side of the seat and fixed in the wiring harness bracket. The wiring harness led out from the lower end of the wiring harness bracket is fixed to the seat cushion frame by a positioning member.

[0006] As a preferred embodiment of this invention, the wire harness bracket is flat. The structure includes two right-angled sections, which are used to avoid environmental components around the seat back frame.

[0007] As a preferred embodiment of this utility model, the bottom shell has a snap-fit ​​structure on the side facing the seat back frame, the snap-fit ​​structure is located near the lower end of the bottom shell and snaps into the seat back frame; the upper cover has lugs on both sides, the lugs have mounting holes, the lugs are located near the upper end of the upper cover and are connected to the seat back frame by screws.

[0008] As a preferred embodiment of this utility model, the bottom shell has four locking points on the side facing the top cover, and the top cover has a locking interface at the position opposite to the locking points. The bottom shell and the top cover are assembled together by a locking mechanism.

[0009] As a preferred embodiment of this utility model, the bottom shell has a fixing groove at the right angle near the seat back frame and a fixing groove at the bottommost position of the bottom shell, and the fixing groove at the bottom of the bottom shell is exposed; the wiring harness inside the car folding seat is led out from the side of the seat and placed in the wiring harness bracket, and the wiring harness is fixed to the fixing groove of the bottom shell with tape.

[0010] Advantages and beneficial effects of this utility model:

[0011] (1) This utility model designs a wire harness bracket, which is fixed to the side of the backrest frame. This changes the traditional way of routing the seat back wiring harness from the back of the seat to routing it from the side of the seat. The lower end of the wiring harness is fixed to the seat cushion frame by a positioning component, and the upper end is bundled and fixed to the backrest frame using the wire harness bracket. This method avoids contact with surrounding sheet metal parts, backrest pivots, plastic parts, and other environmental components, preventing friction and vibration noise caused by contact with these components during backrest movement. In addition, the lower edge of the wire harness bracket is flush with the center of the pivot. During backrest movement, the wiring harness and the wire harness bracket rotate with the backrest around the pivot. The movement segment of the wiring harness is between the backrest pivot and the positioning component, greatly reducing the movement trajectory (shorter movement segment) and the amount of movement allowance (less movement allowance).

[0012] (2) The wire harness bracket provided by this utility model solves the problem of exposed wires at the joint between the seat cushion and the backrest when the car seat backrest rotates forward (the wire harness of this utility model is not exposed); it solves the problem of wire harness accumulation when the car seat backrest rotates, requiring a slack in the wire harness (the wire harness of this utility model does not accumulate); it solves the problem of wire harness friction with the frame and wire harness wear leading to seat malfunction when the car seat backrest is adjusted; it solves the problem of limited space for wire harness routing and wire harness shaping in the car seat backrest, making the back of the seat flat and beautiful, without the need to use a curtain to cover the wire harness.

[0013] (3) The bottom shell of the wire harness bracket of this utility model is provided with two fixing grooves (for fixing the wire harness). The bottom shell and the top cover are connected by a snap-fit ​​method. This design makes the wire harness assembly more convenient and saves time. After assembly, the wire harness is flat and fits the bracket, eliminating the risk of wire harness wear. This solves the problem that the existing wire harness is loosely laid flat in the bracket, and the wire harness moves loosely during the assembly process, making assembly difficult.

[0027] like Figures 1 to 8 As shown, this embodiment provides a wiring harness bracket for wiring a car folding seat. The wiring harness bracket 1 is fixed to the side of the seat back frame 3, and the lower edge of the wiring harness bracket 1 is flush with the center of the backrest pivot 5. The wiring harness bracket 1 includes a bottom shell 11 and a top cover 12. After the bottom shell 11 and the top cover 12 are assembled, a cavity for the wiring harness to pass through is formed between the bottom shell and the top cover. The wiring harness 2 is led out from the side of the seat and fixed in the wiring harness bracket 1. The wiring harness 2 led out from the lower end of the wiring harness bracket 1 is fixed to the seat cushion frame 4 by a positioning member 6, so that the moving section of the wiring harness is between the backrest pivot 5 and the positioning member 6.

[0028] Furthermore, such as Figure 4 , Figure 7 , Figure 8 As shown, in this embodiment, the wire harness bracket 1 is flat. The structure includes two right-angled portions, which are used to avoid surrounding environmental parts of the seat back frame. The bottom shell 11 has a fixing groove 111 at the right-angled portion near the seat back frame and another fixing groove 111 near the bottommost end of the bottom shell 11, with the fixing groove 111 at the bottom end of the bottom shell exposed. After the wiring harness inside the car folding seat is led out from the side of the seat, it is first fixed with tape 7 at the fixing groove 111 at the lower end of the wiring harness bracket, initially fixing the wiring harness bracket 1 position. To prevent the wire harness bracket 1 and wire harness 2 from moving together, the wire harness is then laid flat inside the bottom shell 11 of the wire harness bracket and secured with tape 7 at the fixing groove 111 at the bend of the wire harness bracket. This restricts the shape of the wire harness and ensures that the wire harness 2 fits well with the wire harness bracket 1 at the bend, thus solving the problems of the wire harness 2 being difficult to maintain its bent shape at the bend, the wire harness sticking up, and the wire harness being loose and unable to be assembled with the top cover 12. After the wire harness is flattened, the top cover 12 of the wire harness bracket is assembled with the bottom shell 11.

[0029] Furthermore, such as Figures 3 to 7As shown, in this embodiment, the bottom shell 11 has a snap-fit ​​structure 112 on the side facing the seat back frame 3. The snap-fit ​​structure 112 is located near the lower end of the bottom shell 11 and snaps into the seat back frame 3. The upper cover 12 has lugs 121 on both sides. The lugs 121 have mounting holes 122. The lugs 121 are located near the upper end of the upper cover 12 and are connected to the seat back frame 3 by screws. That is, the wire harness bracket 1 is assembled onto the seat back frame 3 through two mounting holes and the snap-fit ​​structure. The snap-fit ​​structure 112 provides fixed support for the outwardly protruding part of the wire harness bracket, preventing the wire harness bracket from breaking under stress when the wire harness moves.

[0030] Furthermore, such as Figure 3 , Figure 7 As shown, in this embodiment, the bottom shell 11 has four locking points 113 on the side facing the top cover 12, and the top cover 12 has a locking interface 123 at the position opposite to the locking points 113. The bottom shell 11 and the top cover 12 are assembled together by a locking method, forming a cavity (not shown) between the bottom shell and the top cover for the wire harness to pass through.

[0031] The above describes specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
