Description

Vehicle bumper collision detection device Technical Field The utility model relates to the technical field of collision detection devices, in particular to a vehicle bumper collision detection device. Background With the rapid development of the automobile industry, the automobile maintenance amount is rapidly increased, the road traffic safety problem is increasingly remarkable, various collision accidents are inevitably encountered in the running process of the automobile, the performance and the damage condition of the bumper serving as important safety protection components of the front part and the rear part of the automobile are directly related to the safety of personnel in the automobile and the subsequent maintenance cost of the automobile, and the bumper can absorb and disperse part of collision energy during collision to lighten the impact on the automobile body structure and passengers in the automobile, however, the collision caused by different intensities, different angles and objects in different shapes is different. When the existing device is used, only collision objects with a single shape can be simulated, the real situation of the bumper in collision with objects with different shapes cannot be simulated comprehensively, so that the detection result cannot reflect the performance of the bumper in actual use completely, and the comprehensive evaluation and improvement of the bumper are not facilitated, and therefore the vehicle bumper collision detection device is required to be provided. Disclosure of utility model The utility model aims to provide a vehicle bumper collision detection device, which is provided with a collision rod, a moving block, a hemispherical column and other parts, and can simulate collision conditions under different conditions through the moving block which can be movably installed, so that the damage condition of a bumper when the bumper collides with different objects can be conveniently checked, and the problems in the background technology are solved. In order to achieve the above purpose, the present utility model provides the following technical solutions: A vehicle bumper collision detection apparatus comprising: The fixed block, fixedly connected with ram on the lateral wall of fixed block, the outside sliding connection of ram has the movable block, movable block and fixed block sliding connection, fixedly connected with hemisphere post on the lateral wall of movable block, the spout has been seted up to the inside of movable block, the upper end fixedly connected with T shape piece of movable block, T shape piece and spout sliding connection. Preferably, the inside sliding connection of movable block has the spacing, the outside of spacing is provided with the spring. Preferably, a plurality of limit holes distributed in a ring shape are arranged at the upper end of the T-shaped block, and one of the limit holes is in sliding connection with the limit frame. Preferably, the side wall of the fixed block is fixedly connected with a supporting plate. Preferably, the side wall of the fixed block is fixedly connected with a mounting plate, and a plurality of uniformly distributed mounting holes are formed in the upper end of the mounting plate. Preferably, the side wall of the fixed block is fixedly connected with a limiting plate, and the limiting plate is fixedly connected with the fixed block. Preferably, a test carriage is arranged on one side of the fixed block. Compared with the prior art, the utility model has the beneficial effects that: According to the utility model, the collision rod, the moving block, the hemispherical column and other parts are arranged, so that the collision condition of the vehicle and a plane object such as a wall surface or a vehicle tail is reproduced, the arc-shaped surface of the hemispherical column can accurately reproduce the collision contact characteristics of the vehicle and a cylindrical object such as a street lamp pole and a tree, the collision contact characteristics are more in line with actual accident shapes under different conditions than that of a plane collision test, the moving block and the hemispherical column can be quickly disassembled, the moving block and the hemispherical column can be conveniently replaced, and meanwhile, the positions of the moving block and the hemispherical column can be adjusted, so that the detection of different positions of a bumper is facilitated.
