Description
Technical field
The utility model relates to the automotive seat technical field, more particularly, relates to a kind of seat heating system and automotive seat.
Background technology
Along with developing rapidly of contemporary auto-industry, for meeting the continuous lifting of people to the vehicle riding comfort requirement, the seat electric heating system becomes the popular configuration of cold district vehicle in winter increasingly.
By being installed on the work of seat surface sleeve internal electrical heating unit, make the user of seat can directly experience the hot temp effect that comes from seat.It has more direct, rapid, the energy-conservation warm heating service effect of seat heat than mounted air conditioner system.
Common seat heating system consists of electric heating unit and two basic modules of temperature control unit.A groundwork application of this type of seat heating system, adopt exactly a temperature-sensing element can sensing temperature changed to monitor the temperature traverse of the electric heating unit of seat inside, again by the signal feedback that monitors to temperature control unit, signal through temperature control unit is processed, realization is controlled or the magnitude of voltage adjustment the break-make of the working current of seat heating unit, and then realizes meeting the temperature control of seat.
In the practical application of seat heating, once when the temperature get out of hand that heating unit occur, just usually can cause the burning of this seat inside, ablation, and then affect the safe operation of vehicle.
