A kind of car seat heating pad for keeping warm

Abstract

The invention discloses a car seat heating pad for keeping out the cold, which belongs to the technical field of car seat heating pads. By setting insulation covers extending to the top of the self-heating layer on the left and right sides of the electric heating layer, when the electric heating layer is heated, the heat It not only transmits to the self-heating layer, but also transmits to the thermal expansion bag through a pair of fixed sleeves. The volume of a pair of thermal expansion bladders expands after being heated, so as to play a role of attaching to the user's body left and right, increasing the Insulation area, at the same time, the thermal expansion ventilator realizes its ventilation effect after being heated, so that the fixed sleeves at the left and right ends of the electric heating layer can realize the circulation of air, and the gas overflows and diffuses after flowing through the heating chamber, which improves the surrounding temperature of the heating pad. Expand the cold protection range, and the hot air flows through the water bag, and the water vapor formed in the water bag is taken out with the air to increase the humidity in the car. In addition, the multiple self-heating balls on the heat conduction pad are used to generate heat independently, even when the vehicle is not started. In the state, it is also possible to control the thermal pad to achieve auxiliary protection against the cold.

Description

technical field [0001] The invention relates to the technical field of car seat heating pads, in particular to a car seat heating pad for cold protection. Background technique [0002] With the continuous improvement of people's requirements for the comfort of car seats, many car seats are equipped with electric heating devices. Especially for cold seasons, seats equipped with heating pads are very suitable, which can effectively improve the comfort of users. [0003] At present, the electric seat heating device uses the heating wire arranged on the surface of the seat cushion foam to heat the seat. After the heating pad is heated, only the cushion layer is heated, and it only plays a role of local warmth, and the range of protection from the cold is still very limited. In addition, the heating pad is generally connected to the power supply of the car. When the engine is turned off, the heating pad stops heating, resulting in a decrease in the comfort of the occupants of the...
