Provided is a vehicle body structure capable of preventing separation between a bumper beam and a bumper beam mounting member on the non-collision side at the time of an offset collision. The vehicle body structure includes a bumper beam, a pair of bumper beam mounting members, and a pair of holding members. The holding member includes an outer mounting portion for mounting an outer side in the vehicle width direction of the holding member on the bumper beam mounting member, and a front mounting portion for mounting an inner side in the vehicle width direction of the holding member on the front surface portion of the bumper beam. The front mounting portion extends to a position corresponding to a vehicle width direction inner end portion of the bumper beam mounting member in a front-rear direction at least on the front surface portion of the bumper beam.

An upper side joint section that extends inward in a vehicle width direction from a vicinity of a rear side frame and a lateral side joint section that extends downward from the upper side joint section and that is separated in the vehicle width direction from the rear side frame are provided on a rear floor panel of a vehicle body rear part structure.

The rear panel has: a frame joint part to which the rear side frame is joined; a first floor joint part to which the upper side joint section of the rear floor panel is joined; and a second floor joint part to which the lateral side joint section of the rear floor panel is joined. A longitudinal bead is provided on a part of the rear panel between the frame joint part and the second floor joint part. The longitudinal bead extends to a lower end of the rear panel and is opened downward.

An outrigger is connected to a front end part of an apron upper member, and further, is extended from its connected part up to that area of a front side member which is on its front end side and on its outer side in a vehicle width direction so as to be connected to the front side member. One end part of a connecting support member is connected to a connecting portion between the outrigger and the apron upper member. The connecting support member extends inward in the vehicle width direction in a plan view of a vehicle from its connected part, so as to be connected to the front side member.

A shock absorption device includes an inner cylinder assembly threadably engaged within an outer cylinder assembly. The outer cylinder assembly includes a cap shaped member, at least one protruding member, and at least one first spring member. The inner cylinder assembly includes at least one compressive member, at least one second spring member, and at least one movable piston member. When an external impact force is applied to the cap shaped body member, the first threaded portion of the outer cylinder assembly jumps over the second threaded portion of the inner cylinder assembly as provided by elastic movement of the resilient ring member about the cap shaped body member. The thread jumping results in the first spring member compressing and the protruding member pushing the piston member which pushes and compresses the second spring member and the compressive member providing a reactive force to absorb the external impact force.

An energy management system for a vehicle which includes a bumper beam and at least one crush can made from composite materials. The crush can includes a plurality of portions, some portions are frangible and at least one is non-frangible. Bumper beam fixing apertures and vehicle fixing apertures pass through the non-frangible portion such that the crush can is connectable to the bumper beam and the vehicle via fixings which pass through at least one non-frangible portion. This ensures that the bumper beam remains attached to the vehicle in the event of a crash which causes the frangible portions to disintegrate.

Safe protection equipment for all vehicles will significantly reduce the collision force by spring or liquid cylinder when the vehicle bumps to obstacle or two vehicles collide with each other. This equipment can be used on both front and rear of the vehicle. Combination of springs or liquid cylinder with different elasticity can reduce the collision smoothly.

This equipment will protect both vehicles and drivers without changing the current air-bag protection system. It will significantly reduce the damage for serious collision accidents.

This equipment is attached to the vehicle chassis on bottom and frame on top, which will bear the collision force reduced by the spring or liquid cylinder. It might require some design change in vehicle chassis or frame.

One option is to add a pad to pass the reduced collision force to the elastic tire when colliding vehicles are running in straight line.

Safe protection equipment for all vehicles will significantly reduce the collision force by spring or hydraulic cylinder that absorb the colliding force, when the vehicle bumps to obstacle or two vehicles collide with each other. The reduced colliding force will be transferred to the chassis or frame of the vehicle. This equipment can be used on both front and rear of the vehicle. Combination of springs or hydraulic cylinder with different elasticity can reduce the collision smoothly.

This equipment will protect both vehicles and drivers without changing the current air-bag protection system. It will significantly reduce the damage for serious collision accidents.

This equipment can be attached to the vehicle chassis with different ways based on the type of the vehicle. The chassis and the frame may need some enhancement.
