Multi-pose rain test system for vehicle body

Abstract

The invention relates to a multi-pose rain test system for a vehicle body. The system includes a sprinkler system and a chassis, wherein a rectangular frame of an upper end of the chassis is providedwith a moving platform, a lower end center of the moving platform is provided with a lifting-up hydraulic cylinder, an upper end of a piston rod of the lifting-up hydraulic cylinder is connected withthe moving platform through an upper spherical universal joint, a lower end of a casing of the lifting-up hydraulic cylinder is provided with a lower spherical universal joint, four sides of a lower end of the moving platform are provided with hinge shaft supports, each hinge shaft support is fixed with a hinge shaft, jacks are formed between the hinge shafts and the hinge shaft supports, four sides of an upper end surface of the rectangular frame of the chassis are provided with hinge shaft sockets corresponding to the hinge shaft supports, an upper end of each hinge socket is provided with agroove, two walls of the groove are symmetrically provided with through holes, a hinging locking pin driven by a driving device is arranged beside each hinge shaft socket, and the hinging locking pins form hinging locking or unlocking with the hinge shaft sockets and the hinge shaft supports through movement. The system is advantaged in that multi-pose sealing performance testing can be performed, testing is simple and easy to operate, and testing efficiency is high.

Description

technical field [0001] The invention relates to the field of automobile rain test, in particular to a vehicle body multi-position rain test system. Background technique [0002] Automobile rain test refers to testing the sealing performance of the car body through artificially simulated rainfall environment. During the rain test, the car is usually fixed and supported on a platform, and then the body is sprayed through the nozzle. If the body does not leak, the body has good sealing performance. At present, the platform supporting the car is fixed, so it can only detect the sealing performance of the car body when it is in a horizontal posture. The sealing performance test of the car body is not comprehensive, and the test results do not match the actual sealing performance of the car body, which affects the quality of the car body, and the comfort of customers and users after leaving the factory is low. Although now there is also a spray test of an inclined posture after ...

AI Technical Summary

Problems solved by technology

At present, the platform supporting the car is fixed, so it can only detect the sealing performance of the car body when it is in a horizontal posture. The sealing performance test is not comprehensive, and the test results are inconsistent with the actual sealing performance of the car body, which affects the quality of the car body, and the comfort of customers and users after leaving the factory is low.

Although now there is also a spray test of an inclined posture after raising one side of the vehicle body with a large wedge-shaped block, but this method cannot change the inclination angle and direction of the vehicle body at will. It can be realized by manually changing the position of the wedge-shaped pad or changing the specification of the wedge-shaped pad. Not only the replacement is labor-intensive, but also the replacement operation is difficult, which prolongs the test cycle and makes the test efficiency low. Moreover, it is impossible to test any angle of inclination. There are still incomplete tests on the car sound sealing performance, and the test results of the car sound and rain test are inaccurate
