Description
Technical field
The utility model is related to passenger cars under passenger car collision active safety field more particularly to a kind of limit collision operating mode
Life space keep system.
Background technology
The road traffic condition of China is extremely complex, and motor traffic accidents, which has become, caused by automobile collision accident etc. works as
Modern society seriously threatens, injures the big public hazards of human life.
The collision that the passenger car (7 carrying vehicles below) travelled on same road occurs between Heavy Duty Commercial Car
Damage sequence is particularly acute, more dangerous accident：Passenger car travels between two large-scale cargo truck, and rear car is for some reason
Knock into the back passenger car, and passenger car is squeezed into " discus " by front and back two large-scale cargo truck.In accident, passenger car (especially three
Van-type car) often halt due to the upper one third position of A columns is stopped by preceding chassis during being pushed forward,
Final passenger compartment and deck store are squeezed into " discus ", and only because colliding front truck Rear Underrun Protection Devices portions crush occurs for front deck,
Only part front deck pierces under preceding chassis rear overhang, i.e., the dominant touch stress point of passenger car and front truck is strong in such accident
It spends larger passenger compartment rather than is easier to the front deck of crumple deformation.By taking certain three compartment passenger vehicle body height 1.45m as an example, general front
Trailer have the rear overhang of 1~3.5m, chassis height is 1.3~1.5m, in the case where this passenger car does not have wheel, bodywork height
Less than 1.3m, therefore the vehicle can pierce the trailer tailstock, and in view of the Rear Underrun Protection Devices of passenger car collision front vehicles
The shrinkage of front deck afterwards, the length before passenger car pierces under chassis rear overhang are more considerable.
Therefore, in the accident that passenger car is squeezed by two large trucks, a kind of safety for measure of taking the initiative is developed
System reduces before passenger car chassis height pierces under chassis rear overhang, unavoidable in the accident that passenger car is extruded
Under limiting case, in increase accident riding occupant of the car survive probability requirement it is more urgent.
