Wheel retraction device of ADAS test soft collision target platform car

Abstract

The invention relates to the technical field of automobiles, and discloses a wheel retraction device of an ADAS (Advanced Drive Assistance System) test soft collision target platform car, the device comprises a frame consolidation block, a telescopic swing arm and a rocker arm, the telescopic swing arm is hinged with the frame consolidation block, the middle part of the rocker arm is hinged with a frame, and two ends of the rocker arm are respectively hinged with a wheel and the telescopic swing arm; through the device, the wheels can automatically retract into the vehicle body when the target platform fake vehicle is collided, so that the vehicle body bottom plate with higher mechanical strength and a flat surface is in contact with the ground, and the damage to a vehicle wheel system is avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a wheel retracting device for an ADAS test soft collision target platform vehicle. Background technique [0002] The target vehicle is one of the important participants in the real-vehicle test of the ADAS (Advanced Driver Assistance Systems) of the intelligent vehicle. It is mainly used to verify whether the intelligent vehicle has the ability to recognize the surrounding target vehicles and whether it can follow the changes in the driving conditions of the target vehicle ahead. And make corresponding starting, braking, accelerating and other operations. In the process of real vehicle testing, it is inevitable that the smart vehicle will collide with the target vehicle because the technology of the intelligent vehicle is not up to standard. If the target vehicle is used as a real vehicle, it will easily cause damage to the structure and performance of the two vehicles. Unma...

Problems solved by technology

In the process of real vehicle testing, it is inevitable that the intelligent vehicle technology does not meet the standard and collide with the target vehicle. The target vehicle is easy to cause damage to the structure and performance of the two vehicles.

Unmanned soft collision target platform fake car is an emerging type of target vehicle, which integrates all parts except the body into a box (body) less than 20cm high, and the body is built with car-shaped balloons or foam boards It can greatly reduce the loss caused by the collision of two vehicles; however, the wheel subsystem is exposed to the vehicle body and in contact with the ground during the operation of the fake car on the target platform, which will cause damage to the wheel subsystem during the collision.
