Single-side degeneration ODB support and automobile CCB support

Abstract

The invention discloses a single-side degeneration ODB support and an automobile CCB support. Guide grooves with different width and extending to side plates are formed in a top plate of the single-side degeneration ODB support, so that the rigidity of the side, close to the first side plate, of the top plate is less than the rigidity of the other side of the top plate, and when the front end of the ODB support is stressed, the first ends of the guide grooves are prone to be deformed; meanwhile, the rigidity of the guide grooves is decreased due to the existence of degeneration holes, the inclined state of the degeneration holes also enables the guide grooves to be prone to be deformed, the side, close to the first side plate, of a front end region is more prone to be degenerated, so thatthe front end region of the ODB support is integrally deformed towards one side of the first side plate, the external impact force is absorbed, and the energy absorption effect is achieved; and the guide grooves can achieve a certain partition effect while the front end region of the support is deformed, so that the possibility of the deformation of a rear end region of the top plate is reduced, the rigidity of the rear end region is guaranteed, and the energy absorption and support rigidity requirements are met when the overall structure is stressed.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to ODB brackets with one-sided collapse and CCB brackets for automobiles. Background technique [0002] One of the main functions of the ODB (offside deform barrier) bracket is to fix the front end of the CCB to the vehicle body to increase the stiffness of the CCB itself, and the other is to absorb energy in collisions. [0003] As the requirements for the safety of occupants in the car are getting higher and higher, the 64Kph frontal 40% overlapping deformable barrier crash test has become a necessary procedure in the China New Car Evaluation Regulations and the European New Car Safety Evaluation Association test procedures. The program requires the test vehicle to hit the fixed deformable energy-absorbing barrier frontally at a speed of 64Kph with 40% overlap, so the requirements for the ODB bracket are also increased accordingly. [0004] Common ODB brackets on the market have either ...

AI Technical Summary

Problems solved by technology

[0004] Common ODB brackets on the market, either have strong rigidity, which can guarantee a certain rigidity requirement when subjected to external force impact, but the energy absorption effect is poor; or the rigidity is weak, and can effectively absorb energy through deformation, but its structure It is often the overall collapse, which cannot provide sufficient rigidity after collapse; it often cannot meet the requirements of sufficient rigid support after energy absorption, and it is difficult to achieve the contradictory coordination between energy absorption and rigidity
