Vehicle-mounted brake device for automobile rear impact test

Abstract

The invention discloses a vehicle-mounted brake device for an automobile rear impact test, which mainly comprises an electric control device, a pneumatic device and a mechanical connection device. Theelectric control device comprises a controller; the controller is electrically connected with a valve control module, a test trigger interface, a reset button, a trigger switch and a delay module; the test trigger interface is externally connected to the trigger switch; and the trigger switch is attached to the most protruding part of the rear impact surface of an impacted vehicle. The pneumaticdevice comprises a gas cylinder, a pipeline and a leg type device, the gas cylinder is connected with the leg type device through the pipeline, the valve control module is arranged on the pipeline, and the leg type device is a cylinder and piston rod assembly; the mechanical connection device is used to connect the leg type device to a seat and simulate knee and ankle motions. The vehicle-mountedbrake device has the advantages of simple structure, convenient installation, stable and reliable braking effect, and installation and use are not limited by the vehicle type.

Description

technical field [0001] The invention belongs to the technical field of automobile collision tests, and mainly relates to a vehicle-mounted brake device for vehicle rear collision tests. Background technique [0002] Nowadays, the society and the public pay more and more attention to the safety of automobiles, especially the safety of automobiles after collisions. Domestic and foreign automobile regulations and standards have made strict requirements on the safety of automobiles after collisions. The braking ability of the crashed vehicle is one of the important assessment aspects. Both the enterprise R&D test and the model certification test need to be verified by the rear impact test. In the rear collision, the collided vehicle will have different degrees of forward movement after the rear collision, which is prone to secondary collisions. The safety control of the vehicle movement after the collision is an important safety issue in the rear collision test of the car. Ther...
