Description
Technical Field
[0001] The utility model belongs to the technical field of passenger vehicles, in particular to an electric heating assembly for a vehicle seat. Background Art
[0002] Seat heating is a function that improves the comfort of vehicle seats in winter. It heats the seats through the electric heating wire inside the seats and then transfers the heat to the passengers. This function usually has multiple adjustment gears to adjust the temperature as needed. The seat heating switch is usually located on the center console. Some models may be installed on the left side of the main driver's seat or on the driver's seat door. When using seat heating, pay attention to evenly load the seats to avoid point loads, and avoid contact between the seat heating components and moisture to prevent short circuits or electric shocks.
[0003] In the prior art, seat heating uses electric heating wires in the seat to heat the inside of the seat, and transfers the heat to the passengers through heat transfer, so as to improve the discomfort caused by the seat being too cold after being parked for a long time in winter. At present, the basic structure of a relatively mature seat heater is: the lower layer is a layer of non-woven fabric, the heating wire is arranged on the non-woven fabric, the heating wire is fixed to the non-woven fabric with a fixing tape, the knitted fabric is covered on the fixing tape, and the knitted thread is sewn into a shape similar to the seat heating part, and sewn into the seat cover. In order to improve the comfort of the passengers in the car, the seat heating temperature is controlled within a certain range. The backrest heater is connected to the seat cushion heater power supply through a plug-in connector, and the seat cushion heater power supply is connected to the instrument panel wiring harness through a plug-in connector, and then connected to the battery power supply through the seat heating switch, the fuse, and the ignition switch. This structure has the advantages of high comfort and simple structure, but the power consumption is relatively large and the waste heat of the vehicle cannot be fully utilized. Summary of the invention
