Car seat with passive temperature adjusting function and car

Abstract

The invention discloses a car seat with a passive temperature adjusting function and a car. The car seat comprises a seat cushion, a backrest and a temperature adjusting assembly, and the temperatureadjusting assembly includes an air inlet pipe, an exhaust pipe, a seat cushion heating component and a backrest heating component; the seat cushion heating component is disposed in the seat cushion, the backrest heating component is disposed in the backrest, the seat cushion heating component and the backrest heating component both comprise a plate body, a temperature adjusting cavity is formed ineach plate body, an air inlet of each temperature adjusting cavity is communicated with the air inlet pipe, and an exhaust port of each temperature adjusting cavity is communicated with the exhaust pipe; the air inlet of the air inlet pipe receives the air output by a car air conditioning system. Compared with the prior art, the provided car seat with the passive temperature adjusting function and the car have the advantages that the cost is reduced since heating wires are omitted, naturally there is no risk of fire caused by a too high temperature of the heating wires, double adjustment of heating and cooling can be simultaneously performed, and second passive adjustment without active control is achieved.

Description

technical field [0001] The invention relates to automobile technology, in particular to an automobile seat with passive temperature adjustment function and an automobile. Background technique [0002] In recent years, the seat heating function has gradually become one of the mainstream configurations of mid-to-high-end cars. [0003] In the prior art, for a seat with a heating function, a sheet-shaped heating element is arranged in the seat cushion and the backrest, mostly fiber cloth, and a heating wire is arranged on the fiber cloth, and the heating of the seat cushion and the backrest is realized by heating the heating wire. of heating. For example, the authorized announcement number is CN105228492B, the authorized announcement date is July 31, 2018, and the invention patent named "Seat Heater" has a planar heating element (101) with multiple heating wires on the upper surface, including fiber The layer (101b); the buffer part (902) is located on the lower surface of th...

AI Technical Summary

Problems solved by technology

[0005] First, the cost of heating wires is relatively high, so currently only mid-to-high-end cars have the seat heating function, and some mid-to-high-end cars and almost all low-end cars are not equipped with this function

[0006] Second, if the heating wire is heated to an excessively high temperature, there is a risk of fire

[0007] Third, when the temperature is low in winter, the cushion is colder and can be heated, but in summer, the cushion is hotter and cannot be cooled;
