Embodiment

[0036] Embodiment: a system for opening the escape route after a collision in this embodiment, such as figure 1 As shown, it includes a controller 1, and the controller 1 is connected with an acceleration sensor 2, a speed sensor 3, a water pressure sensor 4, a gyroscope 5, a hinge explosive device 6, a skylight explosive device 7, a seatback explosive device 8 and a manual detonation button 9 .

[0037] The hinge explosive device is set at the hinge of the car door. The sunroof explosive device is set at the car sunroof. There are two seatback explosive devices, which are respectively arranged at the junction of the seat back of the driver's seat and the junction of the seat back of the passenger seat and the junction of the seat. Anti-riot steel plates are installed between the seatback explosive device and the occupant.

[0038] The controller is the car's airbag control unit. Each explosive device is an electric detonator. The controller, acceleration sensor, speed se...

Abstract

The invention discloses an escape way opening method and an escape way opening system after crash. The system comprises a controller as well as an acceleration sensor, a speed sensor and a hinge explosion device which are respectively connected with the controller, wherein the acceleration sensor is a triaxial acceleration sensor; and the hinge explosion device is arranged at the automobile door hinge. The controller judges whether crash happens or not through the acceleration sensor, and judges whether the automobile body is static or not through the speed sensor if the crash happens, and the automobile door hinge can be exploded through the hinge explosion device and the automobile doors can be pushed away from the automobile body through the force of explosion if the automobile body is static, so that personnel inside the automobile can escape. The escape way opening method and the escape way opening system can be suitable for all automobiles.

Description

[0001] technical field [0002] The present invention relates to the field of automobile safety, in particular to a method and system for opening an escape channel after a collision or rollover of an automobile Background technique [0003] The inability to open the door during a collision is one of the important causes of casualties. In recent years, there have been more and more forms of collisions, such as frontal or side collisions; too fast speed, emergency braking, causing rollover, and causing the door on the side of the collision to be dented or trapped. If squeezed (especially for models with gull-wing doors), the doors cannot be opened, which delays the escape and rescue time of the occupants, thereby increasing the probability of occupant casualties. [0004] The State Intellectual Property Office of the People's Republic of China published a patent document with the publication number CN101963020A on February 02, 2011. The name is a car door lock system that prev...
