Automobile front collision energy absorption protection structure

Abstract

The invention discloses an automobile front collision energy absorption protection structure. The structure comprises an energy absorption front base, an energy absorption rear base, a fixing bolt, afixing nut and an energy absorption spring, wherein the fixing bolt comprises a bolt head and a column, the bolt head is welded to an automobile front anti-collision beam, and the bolt column is welded to an automobile front longitudinal beam; the bolt column penetrates through the energy absorption front base and the energy absorption rear base and is sleeved with the energy absorption spring, and the energy absorption spring is located between the energy absorption front base and the energy absorption rear base; the fixing nut is in threaded connection with the bolt column in the axial direction of the bolt column; the bolt head, the energy absorption front base, the energy absorption spring, the energy absorption rear base and the fixing nut are sequentially distributed. The protectionstructure has the advantages that the structure is reasonable, when an automobile collides from the front, energy can be effectively absorbed, the energy absorption process is stable and efficient, the energy absorption effect is good, and the safety protection capacity is high; the two-stage protection effect is achieved, avoiding space can be automatically provided, and personal protection of adriver is facilitated.

Description

technical field [0001] The invention belongs to the technical field of automobile protection devices, and in particular relates to an energy-absorbing protective structure for automobile frontal collision. Background technique [0002] Generally, an energy-absorbing box is added to the connection between the front anti-collision beam and the front longitudinal beam of a car, which is used to initially absorb the collision energy of the vehicle and reduce the damage to the occupants. The energy-absorbing box is generally designed with a closed steel plate, and the energy is absorbed through the deformation of the energy-absorbing box. However, the deformation form of the energy-absorbing box is plastic deformation, there are many uncertain factors, and it is impossible to fully absorb energy. Contents of the invention [0003] The invention aims to overcome the deficiencies in the prior art, and provides a vehicle with a reasonable structure, which can effectively absorb e...
