Pressure detection device for vehicle seat

Abstract

The invention discloses a pressure detection device for a vehicle seat, and belongs to the technical field of automobiles, the pressure detection device comprises a bottom frame, the upper surface of the bottom frame is fixedly connected with a base, the upper surface of the base is provided with a soft layer, and the inner wall of the base is slidably connected with the same pull rope through a plurality of formed sliding holes. According to the pressure detection device for the vehicle seat, the pull rope, the ceramic column and the linkage rod are arranged, the synchronous pull rope can be well matched with the tough steel sheet according to the suction force of negative pressure, the seat cannot be too soft, good elasticity and comfort are kept, the good buffering effect on bumping of a vehicle is achieved, the device has a very good protection effect on the lumbar vertebra of a person when being used in a lorry, so that the weight of a small-mass object can be monitored in the whole use state of the device, meanwhile, the device is used for monitoring the riding of a human body, and a good attaching and buffering effect can be synchronously achieved for the lorry.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to a pressure detection device for a vehicle seat. Background technique [0002] Common seat functions include seat memory, seat heating, seat ventilation and seat massage. Seat memory, which can store the seat position, and seat heating refers to the electric heating device in the seat. Most electric heating devices have the function of temperature adjustment, and seat ventilation is the "heat protection device" for car seat air conditioners. In summer, although there is an automatic air conditioner that can maintain a constant temperature in the car, due to the close contact between the occupant's body and the seat, the air in the contact part is not circulated, which is not conducive to sweat removal and makes people feel uncomfortable. The unique ventilation circulation system of the seat ventilation and air conditioner continuously flows fresh air from the small holes on ...

AI Technical Summary

Problems solved by technology

[0003] For the current seat function, the seat of the vehicle needs to have the function of sensing the human body, and it is necessary to distinguish whether it is for placing objects. The current conventional solution is to use pressure detection on both the seat base and the backrest. Sensing unit, and for pressure detection, it needs to be compatible with various functions of the seat. Seat ventilation and seat heating do not affect each other, and it cannot be realized for current car seats. While accurately detecting the human body, it detects the riding weight of the human body at the same time
