Passenger compartment shape retention device and automobile provided with same

Abstract

The invention discloses a passenger compartment shape retention device and an automobile provided with the same, relates to a passenger compartment shape retention device for protecting safety of passengers during collision of an automobile, and belongs to the field of safety devices of automobiles. The passenger compartment shape retention device comprises a front wall plate, an instrument board crossbeam and an additional support beam extending between the front wall plate and the instrument board crossbeam, and a joint of the additional support beam on the instrument board crossbeam is positioned between a steering column mounting support and a second end. The passenger compartment shape retention device is simple in structure, the additional support beam is connected with the instrument board crossbeam and the front wall plate, deformation of the additional support beam, the instrument board crossbeam and the front wall plate which are used as a combination during collision is controllable, and the additional support beam cannot be broken to cause excessively high maintenance expenditure. Besides, the additional support beam is arranged between the instrument board crossbeam and the front wall plate, and the integral collision resistance of the passenger compartment shape retention device is improved, so that rearward movement of the instrument board crossbeam and rearward movement of the front wall plate are effectively controlled, and injury to chests of passengers is relieved.

Description

technical field [0001] The invention relates to a passenger compartment shape maintaining device for protecting occupants in automobile collision, and belongs to the field of automobile safety devices. Background technique [0002] In the event of a car collision, usually, the stiffness of the passenger compartment is directly related to the injury of the occupants (driver and passenger). The greater the stiffness of the passenger compartment, the smaller the deformation of the cabin during the collision, so that the living space of the occupants is guaranteed. , the occupant's injury will be reduced accordingly, and the safety performance of the car is just relatively high. Therefore, in consideration of safety, the passenger compartment must have sufficient rigidity to resist deformation. [0003] The passenger compartment is composed of the front door, A-pillar, dash panel, door sill, roof and B-pillar. These key components must have sufficient rigidity to support the de...

Problems solved by technology

This solution fails to solve the problem from the perspective of the passenger compartment as a whole, and the technical solution it proposes has the following disadvantages: the fracture of the fracture zone in the collision is uncontrollable, even if a small collision occurs, it will fracture, and the maintenance cost is too high
