Efficient seat heating cushion

Abstract

The invention discloses an efficient seat heating cushion which comprises a fabric layer, a middle layer and a heat insulation layer, the fabric layer, the middle layer and the heat insulation layer are sequentially and fixedly connected into a whole from top to bottom, the middle layer is a fabric layer of a multi-layer structure, and a heating circuit is fixed to the side, close to the fabric layer, in the middle layer. The heating circuit is a bridging circuit and comprises heating wires which are fixed in the middle layer in a net shape, and a heat conduction material is added in the fabric layer. The heating circuit is designed to be the bridging circuit and is fixed on the upper surface of the fabric in a weaving manner, so that the heating pad has high strength and high durability, the bridging circuit is more stable compared with a traditional one-way U-shaped structure defined by heating wires, heat of each area is more balanced. The problems that the traditional heating pad is not easy to damage due to the fact that the design thought and the structure are far away from the fabric layer, and the utilization rate of a heat source is not high in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a high-efficiency seat heating pad. Background technique [0002] With the development of economy and technology and the improvement of people's living standards, consumers will pay more attention to the comfort of the vehicle when purchasing a vehicle. As an important equipment decoration inside the vehicle, the car seat is also the part that is most directly in contact with the human body. Therefore, many configurations related to comfort are carried by the seat. Existing car seats are generally composed of cladding materials, filling materials, skeletons, functional equipment, and body connecting materials. Covering materials usually include leather, microfiber, PU leather, PVC leather, fabric fabrics, etc. Filling materials usually include polyurethane foam materials, fiber filling materials, etc. The skeleton is usually a metal pipe fitting plus leaf spring structure.

AI Technical Summary

Problems solved by technology

Since there is an artificial leather base cloth layer, a burnt-on sponge layer, a high-elastic sponge layer, etc. between the heating pad and the cover, it will take a certain amount of time (about 15 minutes) to actually start the electric heating of the seat until the surface of the cover reaches a comfortable temperature. The layout area and area of ​​the pad are affected by the support foam ventilation duct, which is limited to a certain extent, and the current single copper wire in the heating pad is arranged in a "U-shaped" shape, and any breakage of the copper wire will cause electric heating. Functional failure, poor durability and stability of the seat

The heating pad is usually glued on the foam or sewn on the cover, which not only increases the process cost but also affects the environmental protection of the whole vehicle
