Seat heating device and seat

Abstract

The invention discloses a seat heating device and a seat. The seat heating device comprises a vehicle-mounted power supply, an energy accumulator, a controller, a heating mat and a switch module; an input end of the energy accumulator is connected with the first end of the switch module, the second end of the switch module is connected with an output end of the vehicle-mounted power supply, the third end of the switch module is connected with the heating mat, and a control end of the switch end is connected with the output end of the controller; the controller is used for controlling the vehicle-mounted power supply to charge the energy accumulator through the switch module according to a charging command, and further used for controlling the energy accumulator to heat the heating mat through the switch module after receiving a heating command; and the discharge current of the energy accumulator is larger than the output current of the vehicle-mounted power supply. According to the seat heating device and the seat, the temperature of the heating mat can be increased quickly during use, the temperature of the seat is further risen quickly, the requirements of users are advantageously met, and the experience of the users is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicles, in particular to a seat heating device and a seat. Background technique [0002] With the development of industrial technology and the improvement of people's living standards, automobiles have become an important means of transportation in people's daily lives. In order to improve the comfort of the user, a heating pad is usually provided on the seat, and the heating pad is directly heated by the vehicle power supply. However, since the on-board power supply stores electric energy in a chemical energy conversion method, and the conversion speed is slow, the output power to the heating pad is effective. When the outdoor ambient temperature is very low, the on-board power supply cannot quickly heat up the heating pad, which is difficult to satisfy users. demand and affect user experience. [0003] In view of this, how to provide a seat heating device and a seat that so...
