Description

Technical Field

[0001] The utility model relates to the technical field of vehicle body testing platform devices, in particular to a vehicle body multi-posture tilting rain testing platform. Background Art

[0002] Car rain test refers to testing the sealing performance of the car body in an artificially simulated rainfall environment when the car body is in a stationary state. During the rain test, the car is usually fixed on a platform and then sprayed with a nozzle. The door opening and closing torque parameters required for the door opening and closing of the car body in different postures and angles, and the sealing performance data required for the development of new models are obtained to judge the body sealing performance in different states, and verify whether the door opening and closing torque meets the design indicators. According to the torque performance parameters obtained in the test, the weight and structural design of the door and the flexibility of the door hinge are adjusted. It is also necessary to verify whether the car body rain sealing performance meets the design indicators. Finally, the sealing performance parameters obtained from the test are used to improve the body sealing method and sealing materials.

[0003] For example, a vehicle body multi-posture rain test system with publication number CN109520675A includes a spray system and a chassis. A movable platform is provided in the upper end frame of the chassis. A lifting hydraulic cylinder is provided at the center of the lower end of the movable platform. The upper end of the piston rod of the lifting hydraulic cylinder is connected to the movable platform through an upper spherical universal joint. A lower spherical universal joint is provided at the lower end of the cylinder shell of the lifting hydraulic cylinder. Hinge shaft brackets are provided on the four sides of the lower end of the movable platform. A hinge shaft is fixed in each hinge shaft bracket to form a socket between the hinge shaft and the hinge shaft bracket. Hinge shaft sockets are provided on the four sides of the upper end surface of the chassis frame to correspond to the hinge shaft bracket. A groove is provided on the upper end of each hinge shaft socket, and through holes are symmetrically provided on both walls of the groove. An articulated locking pin driven by a driving device is provided next to each hinge shaft socket. The articulated locking pin forms an articulated lock or unlocking of the hinge shaft socket and the hinge shaft bracket through movement.

[0004] The above-mentioned device is composed of a movable platform, a platform mounting bracket, a jacking main cylinder assembly, a cylinder latch assembly, a hydraulic system, and a control system. The hinge shafts on the movable platform are all placed on the hinge seat, all the latch cylinders are extended, and the latches are inserted into the square holes through the hinge seat to configure a rotatable hinge. The jacking cylinder is in the shortest stroke position. When the posture needs to be adjusted, the latch cylinder is extended, and the latch is inserted into the square holes through the hinge seat to configure a rotatable hinge to adjust to different posture forms. However, this type of posture adjustment method results in that it can only perform torque and spray sealing tests in some postures, and cannot perform multi-angle tests in the same posture. If multi-angle tests are required, it is necessary to configure a wedge-shaped collapse platform with many angle specifications. In addition, the posture and angle cannot be changed automatically. The posture change requires the replacement of the wedge-shaped collapse platform or the change of the collapse platform position, which is labor-intensive and has a long interval between posture changes, resulting in the inability to perform continuous programmed spray tests. The above shortcomings will lead to incomplete data required for body research and development, or a long data collection cycle, resulting in many disadvantages such as a long body research and development cycle and many quality problems.
