Problems solved by technology

The first heating method needs to be equipped with a relatively expensive programmable switch, and can only implement temperature control on one heating pad
The second heating method needs to be implemented through a relatively complicated parallel and series conversion circuit. The cost of circuit implementation is relatively high. At the same time, this solution must and can only control two heating pads. The total power is only 1 / 4 of the parallel circuit, resulting in a significant reduction in heating efficiency and a significant reduction in temperature rise speed

Description

technical field [0001] The invention relates to the technical field of seat heating systems, in particular to a seat heating system. Background technique [0002] The existing seat heating system usually realizes the adjustment function of the heating temperature through two methods. The first is realized through the cooperation of multi-position programmable switches with built-in single-chip microcomputer chips and temperature sensors. The second is to use the three-speed switch and the relay to work together, so that the two heating pads are connected in parallel and in series to realize the conversion of high and low power, and finally realize the conversion of high and low temperature adjustment. The first heating method requires expensive programmable switches and can only control the temperature of one heating pad. The second heating method needs to be implemented through a relatively complicated parallel and series conversion circuit. The cost of circuit implementa...
