Passenger car protection seat system

Abstract

The invention provides a passenger car protection seat system. The passenger car protection seat system comprises a gyroscope, an acceleration sensor, an electronic control unit, an execution mechanism and seats; the gyroscope and the acceleration sensor are located at the floor of a passenger compartment at a passenger car body, wherein the gyroscope is in charge of measuring a lateral inclined angle speed of the car body, the acceleration sensor is in charge of measuring a lateral inclined angle acceleration of the car body, the electronic control unit calculates a real-time car body lateral inclined angle, when the car body inclined angle reaches a preset value of 45 degrees, the electronic control unit sends a signal to the execution mechanism, and the passenger car protection seat system is activated. When a passenger car rolls over, the seats of the passenger car are restrained, therefore the motion track of passengers is effectively restrained, it is ensured that passengers are in the living space, the passengers are prevented from being beyond the living space and being injured, and the injury protection capacity of the passengers is improved.

Description

technical field [0001] The invention relates to the technical field of passenger car structures, in particular to a passenger car protective seat system. Background technique [0002] According to incomplete statistics, in the past three years, the annual death toll caused by passenger car rollover accidents accounted for about 35% of the total number of passenger car accident deaths, while the number of injured people caused by rollover accidents accounted for about 46% of the total number of passenger car accident injuries. Passenger car rollover is a collision accident with fast speed and short duration. The occupants have no self-protection ability in the accident. Even under the condition of using seat belts, the large deformation of the body will still squeeze the head and torso of some occupants. Its safety poses a hazard. It can be seen that the protection effect of the traditional passenger car structure on the occupants in the case of a rollover of the passenger ca...

Problems solved by technology

Passenger car rollover is a collision accident with fast speed and short duration. The occupants have no self-protection ability in the accident. Even under the condition of using seat belts, the large deformation of the body will still squeeze the head and torso of some occupants. Its safety poses a hazard. It can be seen that the protection effect of the traditional passenger car structure on the occupants in the case of the passenger car rollover is very limited.
