Heating seat cushion

Abstract

The invention discloses a heating seat cushion comprising a seat cushion body, a heating core body and a temperature control device. The temperature control device is connected with the heating core body. The heating core body is placed inside the seat cushion body and comprises heating wires and a carbon fiber heating layer, wherein the carbon fiber heating layer is a latticed heater formed by weaving carbon fiber heating wires. The heating wires are in two groups. The two groups of heating wires are respectively arranged at two ends of the carbon fiber heating layer and connected with the carbon fiber heating wires on the carbon fiber heating layer in a hot pressing mode. The two groups of heating wires are both connected with the temperature control device. The heating seat cushion further comprises an inflaming retarding layer. The inflaming retarding layer is placed inside the seat cushion body and covered on the carbon fiber heating layer and the two groups of heating wires. By means of the method, the heating seat cushion can be folded and pressed. The connection between the heating wires and the carbon fiber heating wires is stable, so that the heating effect of the whole heating seat cushion can not be affected by the fact that part of the carbon fiber heating wires is broken.

Description

technical field [0001] The invention relates to a cushion, in particular to a heating cushion made of carbon fiber which can be heated. Background technique [0002] In the cold winter, people usually use cushions on the seats to keep warm, but the general cotton cushions are not warm enough, so drivers of some low-end and medium-sized vehicles with poor heating settings generally use electric heating pads when driving. Heated cushions for warmth. At present, the electric heating cushions on the market generally have internal heating lines arranged in parallel longitudinal or horizontal directions. The cushions are inevitably folded or squeezed during use. If a heating line breaks, the heating pad where the heating line is located Area just can not get heating, thereby can not guarantee heating pad overall heating, can not provide better warming effect for the driver. On the other hand, the heating circuit in the prior art is generally made of non-metallic materials such a...

AI Technical Summary

Problems solved by technology

The use of copper sheets to connect the heating wire and the heating circuit has many disadvantages. On the one hand, the copper sheet is displaced due to frequent use of the heating cushion, which makes the contact between the heating wire and the heating circuit poor; on the other hand, the copper sheet is easy to break, and the electric heater After the wire is energized and heated, the heat cannot be transmitted to the heating circuit, so that the heating cushion loses its heating effect
