Deformation set for anti-collision on side of manned vehicle, and manned vehicle with the set

Abstract

A side collision anti-side body deformation device for a passenger car and a passenger car with an anti-side body deformation device, the anti-side body deformation device is installed between the power channel of the vehicle body and the B-pillar of the side body of the vehicle body, including: energy absorption Box, horizontal support rod, trapezoidal support plate, two horizontal support rods are respectively arranged on both sides of the energy absorption box, a trapezoidal support plate is arranged at the connecting end of the horizontal support rod and the energy absorption box, and the horizontal support rod is fixed on the trapezoidal support by bolts The other end of the transverse support rod is fixedly connected to the B-pillars on both sides of the vehicle body, and the energy absorption box is a rectangular integral metal thin-wall cavity shell, which is located above the power channel of the vehicle body. In a side collision of a car, when the side B-pillar is hit, the power channel, energy absorption box, body floor, lateral support rod and B-pillar are sequentially deformed, and the overall structure of the car body is used to resist the deformation of the side of the impact and reduce the deformation of the B-pillar on the side of the impact The deformation speed of the amount, B-pillar and door delays the time when the collision side body hits the occupant.

Description

technical field [0001] The invention relates to an automobile safety device, in particular to an automobile side collision anti-side body deformation device. Background technique [0002] For passenger cars currently produced in China, including sedans, SUVs, and MPVs, their structures have poor side impact resistance and occupant protection. In 2006, my country will enforce the "Occupant Protection for Side Collisions of Automobiles". Safety and compliance with the "Occupant Protection of Automobile Side Collision" regulations that are enforced by the country, many solutions have been proposed, but mainly to strengthen the rigidity of the door and improve the energy absorption capacity of the door, such as adding appropriate elastic elements in the door to achieve The purpose of buffering and prolonging the collision time, but the effect is not obvious.

Problems solved by technology

[0002] For passenger cars currently produced in China, including sedans, SUVs and MPVs, their structures have poor side impact crashworthiness and occupant protection performance.

In 2006, my country will enforce the "Occupant Protection for Side Collisions of Automobiles". Safety and compliance with the "Occupant Protection of Automobile Side Collision" regulations that are enforced by the country, many solutions have been proposed, but mainly to strengthen the rigidity of the door and improve the energy absorption capacity of the door, such as adding appropriate elastic elements in the door to achieve The purpose of buffering and prolonging the collision time, but the effect is not obvious

At present, there is no effective way to prevent the large deformation of the B-pillar of a car, and the torso of the human body is inside the B-pillar. During the collision, the B-pillar of the car body and the door will directly hit the torso of the occupant, causing serious injury or even death to the occupant.
