Automobile seat heating cushion

Abstract

The invention discloses an automobile seat heating cushion. The automobile seat heating cushion comprises a heating seat cushion and a heating device arranged in foams of the heating seat cushion, wherein the heating device comprises a bent circulating heat conduction pipe; a liquid outlet end of the circulating heat conduction pipe is communicated with a liquid storage tank; a liquid inlet end of the circulating heat conduction pipe is communicated with a heating chamber; a heating wire is arranged in the heating chamber and is connected with a control unit through a lead wire to form a loop; and the heating wire comprises at least two heating wire units which are not connected. The heating cushion disclosed by the invention utilizes conductive liquid to heat; once if the conductive liquid leaks, the amount of the conductive liquid in the heating chamber is reduced, so that the heating wire is in short circuit and the power can be automatically off, and furthermore, the protection effect is realized and the safety accidents are not caused; and furthermore, a heat sensor is used for feeding a monitored temperature back to the control unit and the control unit is used for adjusting the heating temperature according to the received temperature and the temperature needed by a driver, and the automobile seat cushion is relatively comfortable.

Description

technical field [0001] The invention relates to the heating of vehicle seats, in particular to a car seat heating pad. Background technique [0002] At present, car seats are generally equipped with heating pads, mainly through the installation of heating harnesses in the seats. The heating harnesses are metal wires, and metal wire heating has two main disadvantages. 1. Magnetic radiation affects health, 2. Metal wires are easy to fatigue After breaking, the heating function is lost after breaking, and the contact area of ​​the metal wire at the breaking point is small, and the local resistance is large, resulting in extremely high local temperature and easy fire and safety accidents. Contents of the invention [0003] The object of the present invention is to provide a heating safety car seat heating pad aiming at the defects of the existing structure. [0004] The technical solution adopted by the present invention to solve the technical problem is to provide a car seat...
