Cover plate for covering surface of collision pit

Abstract

The invention discloses a cover plate for covering the surface of a collision pit, which comprises a framework formed by a plurality of cross beams and a plurality of longitudinal beams, support units formed by adjacent cross beams and adjacent longitudinal beams, and transparent panels correspondingly arranged in the support units, wherein the levelness of the transparent panels can be regulated via a first regulation device; the level surface of the framework can be regulated via a second regulation device; and the upper surface of the whole cover plate is surely on the same plane with the surface of a test track via the regulation. The cover plate for covering the surface of the collision pit satisfies demand for a test, has a simple structure, and is convenient, quick and accurate to regulate; and in addition, with the adoption of the structure, frequent maintenance of the collision pit and the remounting of the cover plate, which are caused by the impact of the collision test, can be avoided, and as a result, cost is saved and efficiency is improved.

Description

technical field [0001] The invention relates to the field of automobile safety testing, in particular to a cover plate for covering the surface of a collision pit. Background technique [0002] With the development of the automobile industry and the improvement of traffic roads, the normal driving speed of automobiles has reached a very high speed. If an accident occurs, it will seriously threaten the safety of life and property. Therefore, all automobile-producing countries attach great importance to the improvement of automobile safety performance. . At present, the determination of automobile safety indicators is mainly obtained by the method of automobile real vehicle crash test. In the test, high-speed cameras are used to take pictures of the damage process of various parts of the automobile and record the data. Especially for the shooting of the bottom of the vehicle body, it is usually necessary to set up a pit under the fixed barrier, in which reflectors, high-speed...

Problems solved by technology

[0003] However, there are still some defects in the traditional cover plate during the test process: for example, the cover plate is customized according to the structural size of the pit, and it will be fixed and cannot be adjusted after being installed on the pit; If the cover plate is displaced or deflected due to slight damage, the test can no longer be carried out, and the pit must be repaired and the cover plate must be reinstalled, which will undoubtedly cause a waste of time, increase the test cost and affect the test process
