A kind of preparation technology of car seat heating pad

Abstract

The invention discloses a preparation process of an automobile seat heating pad, which belongs to the technical field of heating pad preparation. The preparation process of an automobile seat heating pad can be controlled from inside and outside through the setting of inner support contacts and outer limit ball chains. The bending and non-bending parts of the heating wire are limited, so that when the heating wire is subjected to a force that changes in direction and magnitude, it is not easy to shift or squeeze inward or outward due to the change of force, so that it is effective Reduce the breakage of the heating wire during use and prolong the practical life of the heating pad. At the same time, through the joint action of the two, it can effectively ensure that adjacent heating wires are difficult to approach each other, thereby effectively avoiding local overheating. The condition can effectively ensure the uniform heating of the heating pad, thereby effectively improving the safety during use, and the heat storage of the two can prolong the heating time after parking and turning off the engine, and improve the comfort of the occupants in the car.

Description

technical field [0001] The invention relates to the technical field of heating pad preparation, and more specifically, relates to a preparation process of a car seat heating pad. Background technique [0002] The car seat heating pad has a bending resistance of more than 25,000 times. It is the best substitute for carbon fiber or ordinary electric heating wire seat heating pads. The back and base layers are heated at a constant temperature, which can bring warmth to the driver and relieve back pain. comfort. [0003] When in use, the user sits on the seat, and due to the movement of the user, there will be pressure on the heating wire, and the direction of the force will deviate with the movement of the user, which will cause the heating wire to continuously shift back and forth , so that the bending part of the heating wire is prone to breakage, which reduces the service life of the heating pad, and when the heating wire is moving, some adjacent heating wires tend to appro...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the object of the present invention is to provide a preparation process for the heating pad of the car seat, which can realize the uniform heating of the heating pad by bending and attaching the electric heating wire to the non-woven fabric, and at the same time through the inner support The setting of the contacts and the outer limiting ball chain can limit the bending and non-bending places of the heating wire from inside and outside, so that when the heating wire is subjected to a force with a constantly changing direction, it is not easy to be damaged due to the change of force. Displacement or inward or outward extrusion can effectively reduce the breakage of the heating wire during use and prolong the practical life of the heating pad. At the same time, through the joint action of the two, it can effectively ensure the adjacent heating wire It is difficult for the wires to come close to each other, which can effectively avoid local overheating, effectively ensure the uniform heating of the heating pad, and effectively improve the safety during use, and the heat storage of the two can prolong the heating time after parking and turning off , improve the comfort of the occupants
