Abstract

The invention discloses an impact test device for an automobile door trim panel. The impact test device comprises a first metal plate block, a second metal plate block, at least one fixed support andat least one sliding support; clamping grooves are formed in the surface sides of the first metal plate block and the second metal plate block, so that the vehicle door trim panel is connected with the first metal plate block and the second metal plate block through the clamping grooves in a buckling manner; one end of the first sheet metal block is rotationally connected to the fixed support, andone end of the second sheet metal block is rotationally connected to the sliding support; the other end of the first metal plate block is rotationally connected with the other end of the second metalplate block. The state of a vehicle door inner metal plate of being bent towards the surface side when suffering impact is simulated and the stress state of the vehicle door trim panel when an actualvehicle is subjected to side collision is simulated, so that whether the flexural rigidity of the vehicle door trim panel and the buckling connection reliability of the vehicle door inner metal platemeet the safety performance requirements or not can be independently verified without a whole vehicle test.

Description

technical field [0001] The invention relates to the technical field of automobile passive safety, in particular to an impact test device for an automobile door trim panel. Background technique [0002] The sharp increase in the number of cars has led to frequent road traffic accidents, and the probability of side collision accidents of vehicles is relatively high. At present, the safety performance of automobiles in the state of side collision or side slanted column collision has become an important part of evaluating the safety performance of automobiles. [0003] In the case of a side collision or a side slanted column collision, the door trim panel will be bent, or the connection with the door inner sheet metal will fail, resulting in mutual contact between the door trim panel and the side airbag deployed on the side of the car seat , As a result, the side airbags cannot be deployed normally, thereby failing to provide effective protection for the occupants in the vehicl...
