Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to an automobile seat harness clamping structure and a seat foaming mold thereof. Background Art

[0002] Traditional automotive seat wiring harnesses are secured with sheet metal, welded to the seat frame wires and embedded in the foam. The seat harnesses are then clipped onto the sheet metal. As seat comfort features increase, wiring harness design becomes more complex. Traditional sheet metal securing methods present the following issues: 1. Overall weight increases. While some sheet metal is welded to the seat's support wires, others require additional wires to secure them to the seat frame, resulting in increased weight. 2. Increased welding processes increase costs. 3. The limited space between the sheet metal and the frame wires prevents flexible adjustment of the wiring harness securing points. Utility Model Content

[0003] In response to the problems existing in the above-mentioned prior art, the present invention aims to provide a car seat wiring harness clip-on structure and its seat foaming mold to solve the problems that the existing wiring harness fixing structure has limited spatial arrangement and the existing wiring harness fixing structure will cause the seat weight to increase and the cost to rise.

[0004] In order to achieve the above-mentioned purpose, the utility model proposes a car seat wiring harness clamping structure, including seat foam and Christmas tree buckle, the Christmas tree buckle is provided with a clamping groove for clamping the wiring harness, and also includes a disc part, the center of the disc part is a clamping hole matching the Christmas tree buckle, the disc part is pre-embedded in the seat foam and formed integrally with the seat foam, the disc part includes an inner ring section and an outer ring section, the inner ring section is sunken relative to the outer ring section, and the two are connected by a transition section, and a number of through holes are arranged circumferentially on the outer ring section, the clamping hole of the disc part is exposed outside the seat foam, and the Christmas tree buckle is clamped into the clamping hole from the outside of the seat foam.

[0005] In the above solution, the transition section is a tapered stepped structure, which increases the contact surface and further enhances the fixing effect between the disc and the seat foam.

[0006] In the above solution, the surface of the inner ring segment is flush with the back surface of the seat foam, so that the card hole is exposed outside the seat foam.

[0007] In the above solution, the through holes are arc-shaped strip holes, and the through holes are evenly distributed around the circumference. The through holes play the role of reducing weight and increasing the fixing effect between the disc and the seat foam.

[0008] The present invention also proposes a seat foaming mold, which is suitable for the above-mentioned seat foaming. The disc parts are metal parts. Magnets are embedded in the positions corresponding to the disc parts on the seat foaming mold. Before the seat foaming is formed, the disc parts can be pre-magnetically fixed to the corresponding magnets.

[0009] The present utility model also proposes a seat foaming mold, which is suitable for the above-mentioned seat foaming. The disc parts are plastic parts. Positioning columns are provided at the positions of the card holes of each disc part on the seat foaming mold. Before the seat foaming is formed, the disc parts can be pre-fixed on the corresponding positioning columns through the card holes.

[0010] The beneficial effects of the utility model are:

[0011] 1. Improved flexibility: The disc can be moved and placed within the seat foam according to the desired position (placed before foaming), which increases design flexibility. Compared with existing technologies, it is no longer restricted by the layout of the foam space, and the wiring harness fixing points can be arranged more flexibly. 2. Reduced weight: The through holes on the disc can reduce weight, and there is no need to add skeleton wire. Compared with existing technologies, this effectively reduces the overall weight of the seat foam, which is conducive to the lightweight design of automobile seats. Lightweight design can improve the fuel efficiency of automobiles and reduce emissions. 3. Reduced costs: The disc does not need to be welded to the skeleton wire, which reduces the welding process of sheet metal during the production process and reduces production costs.
