Front longitudinal beam energy absorption structure for frontal offset collision

Abstract

The invention discloses a front longitudinal beam energy absorption structure for frontal offset collision. The structure is provided with a solid energy absorption rod (3), a solid rod fixing supportbody (5) fixedly connected with a front longitudinal beam is arranged on the front longitudinal beam, and the solid energy absorption rod (3) extends out of the solid rod fixing support body (5) towards the front of a vehicle. By the adoption of the technical scheme, an overlapping amount generated when 25% of position collision occurs on a front face is effectively increased, the front longitudinal beam is increased to participate in deformation, and energy transmission is dispersed and reduced; and therefore, the damage of collision to the vehicle structure and the harm to drivers and passengers are greatly reduced, and a living space of the drivers and the passengers is increased.

Description

technical field [0001] The invention belongs to the technical field of automobile safety, and relates to the technology for reducing collision damage of automobiles. More particularly, the present invention relates to a front side member energy-absorbing structure for a frontal offset collision. Background technique [0002] At present, in the automotive field, in the event of a frontal 25% offset collision of most models, the energy-absorbing longitudinal beams at the front of the vehicle cannot disperse and absorb the energy brought by the collision. The beam and the collision rigid barrier structure cannot be overlapped, resulting in the inability to absorb and disperse energy, resulting in greater damage to the overall vehicle passenger compartment structure, and more fatal injuries to drivers and passengers. Contents of the invention [0003] The invention provides a front longitudinal beam energy-absorbing structure for a frontal offset collision, and the purpose is...
