Description

Technical Field

[0001] The present invention belongs to the technical field of automotive seats, and particularly relates to a wiring method for a wiring harness of an automotive folding seat. Background Art

[0002] The existing wiring harness arrangement scheme for automotive folding seats is to route the wiring harness from the rear of the seat. In this wiring method, when the backrest is folded to the frontmost position, a large margin needs to be reserved for the wiring harness, and the exposed wiring harness can be seen behind the seat. When the seat is reset to the normal state, there will be a pile-up of the wiring harness, which needs to be covered with a shielding curtain, affecting the aesthetics. At the same time, when the backrest moves, the wiring harness will rub against the surrounding skeleton, posing a risk of damage to the wiring harness. Summary of the Invention

[0003] In view of the above technical problems and disadvantages, the purpose of the present invention is to provide a wiring method for a wiring harness of an automotive folding seat, which changes the routing of the traditional seat backrest wiring harness from the rear of the seat to the side of the seat, designs a wiring harness bracket to limit the routing and shape of the wiring harness, and avoids easy contact with the surrounding environmental components when the backrest moves; at the same time, the wiring harness rotates around the backrest rotation axis through the wiring harness bracket, greatly reducing the movement trajectory and the movement margin of the wiring harness.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A wiring method for a wiring harness of an automotive folding seat, the method comprising the following steps:

[0006] Step 1. Design a wiring harness bracket, the wiring harness bracket comprising a bottom shell and an upper cover, and a cavity for the wiring harness to pass through is formed between the bottom shell and the upper cover after the bottom shell and the upper cover are assembled;

[0007] Step 2. The wiring harness inside the automotive folding seat is led out from the side of the seat, the wiring harness is laid flat in the bottom shell, and the wiring harness is bundled and fixed to the bottom shell with tape. After the wiring harness is fixed, the upper cover of the wiring harness bracket is assembled with the bottom shell;

[0008] Step 3. Fix the wiring harness bracket to the side of the seat backrest skeleton so that the lower edge of the wiring harness bracket is flush with the center of the backrest rotation axis;

[0009] Step 4. Fix the wiring harness led out from the lower end of the wiring harness bracket to the seat cushion skeleton through a positioning member so that the moving section of the wiring harness is between the backrest rotation axis and the positioning member.

[0010] As a preference of the present invention, the wiring harness bracket is of a flat type structure, including two right-angle portions, and the two right-angle portions are used to avoid the surrounding environmental components of the seat backrest skeleton.

[0011] As a preference of the present invention, a clamping structure is provided on one side of the bottom shell facing the seat backrest frame. The clamping structure is arranged near the lower end of the bottom shell and is clamped with the seat backrest frame. On both sides of the upper cover, there are lugs provided with mounting holes. The lugs are arranged near the upper end of the upper cover and are connected to the seat backrest frame by screws.

[0012] As a preference of the present invention, four clamping points are provided on one side of the bottom shell facing the upper cover. At positions opposite to the clamping points on the upper cover, there are clamping interfaces. The bottom shell and the upper cover are assembled together by clamping.

[0013] As a preference of the present invention, fixing grooves are provided at the right-angle part of the bottom shell near the seat backrest frame side, and fixing grooves are also provided at positions near the lowermost end of the bottom shell, and the fixing groove at the lower end of the bottom shell is exposed. After the wire harness in the folding car seat is led out from the side of the seat, it is first fixed at the fixing groove at the lower end of the wire harness bracket with tape, then the wire harness is sorted and laid flat in the bottom shell of the wire harness bracket, and is fixed and bundled with tape at the fixing groove at the turning position of the wire harness bracket.

[0014] Advantages and beneficial effects of the present invention:

[0015] (1) In the present invention, the traditional wire harness of the seat backrest is changed from routing behind the seat to routing from the side of the seat. A wire harness bracket is designed. The lower end of the wire harness is fixed to the seat cushion frame by a positioning part, and the upper end uses the wire harness bracket to shape the wire harness and fix it to the backrest frame. This way can avoid surrounding sheet metal parts, backrest rotating shafts, plastic parts and other environmental parts, and prevent friction, vibration and abnormal noise from occurring when the backrest moves and contacts the surrounding environmental parts. In addition, the lower edge of the wire harness bracket of the present invention is flush with the center of the rotating shaft. During the movement of the backrest, the wire harness and the wire harness bracket rotate around the backrest rotating shaft with the backrest as the center. The moving section of the wire harness is between the backrest rotating shaft and the positioning part, greatly reducing the movement trajectory (short moving section) and reducing the movement margin of the wire harness (less movement margin).

[0016] (2) The wiring method provided by the present invention solves the problem of exposed wires at the joint of the seat cushion and the backrest when the car seat backrest rotates forward (the wire harness of the present invention is not exposed); solves the problem of the need to reserve a margin for the wire harness and the problem of wire harness accumulation when the car seat backrest rotates (the wire harness of the present invention has no accumulation); solves the problem of friction between the wire harness and the frame and the problem of wire harness wear leading to seat function failure when the car seat backrest is adjusted; solves the problem of narrow wiring space for the car seat backrest wire harness and the problem of wire harness shaping.

[0017] (3) After wiring the wire harness using the wiring method of the present invention, the rear of the seat is flat and beautiful, and there is no need to use a shielding curtain to shield the wire harness.

[0018] (4) There are two fixing grooves (for fixing the wire harness) on the bottom shell of the wire harness bracket of the present invention. The bottom shell and the upper cover are connected by a snap-fit method. This design makes the wire harness assembly more convenient, saves time, and after assembly, the wire harness is flat and fits well with the bracket, without the risk of wire harness wear, solving the problem that the existing wire harness is loosely laid flat in the bracket, and the wire harness is loose and moves during the assembly process, making the assembly difficult.
