Support used for collecting car collision test information

Abstract

The invention discloses a support used for collecting car collision test information. A base of the support is provided with an installing face used for fixedly installing a vehicle to be tested. A first frame body of the support is detachably connected with the base and is arranged in the manner that the first frame body can rotate around a first rotation center line relative to the base. The first rotation center line is perpendicular to the installing face. A second frame body is detachably connected with the first frame body and is arranged in the manner that the second frame body can rotate around a second rotation center line relative to the first frame body. The second rotation center line is perpendicular to the first rotation center line. The second frame body of the support is provided with a light supplementing lamp and a camera installing connector. The light beam direction of the light supplementing lamp and the framing direction of a camera are roughly homonymous with thethird rotation center line. The third rotation center line is perpendicular to the first rotation center line and the second rotation center line. According to the scheme, by means of structural optimization, the camera and the light supplementing lamp are installed synchronously, and on the basis of meeting the requirement for the frame definition, the requirement for shooting of multiple portions of safety tests can be met.

Description

technical field [0001] The invention relates to the technical field of automobile testing, in particular to a bracket for collecting automobile collision test information. Background technique [0002] Automobile crash test is an instantaneous process, and it is necessary to arrange high-speed cameras in the corresponding parts to collect the movement changes of the dummy during the test, as well as the status of airbags and seat belts, so as to describe and evaluate the safety of the vehicle as a whole. [0003] As we all know, according to different test requirements, high-speed cameras need to be set based on the position of the shot. See figure 1 , which shows a typical existing high-speed camera bracket structure. The bracket is generally used to be installed on the ground in the car to shoot the movement of the dummy's feet, and the scene used is relatively simple. Limited by its own structure, it cannot adjust the angle, and cannot adapt to the shooting needs of di...

AI Technical Summary

Problems solved by technology

The bracket is generally used to install on the ground in the car to shoot the movement of the dummy's feet, and the scene used is relatively simple

Limited by its own structure, the angle cannot be adjusted, and it cannot adapt to the shooting needs of different parts

[0004] In addition, the space inside the car is relatively narrow and the brightness is insufficient. Due to the short exposure time and high frame rate of high-speed cameras, sufficient light is required to capture clear images.

figure 1 The bracket shown in above cannot be used to install the supplementary light, and a separate supplementary light bracket is required to install the supplementary light, and the test preparation takes a long time
