Ultra-thin power assembly for automatic driving collision target vehicle carrying platform

Abstract

The invention relates to an ultra-thin power assembly for an automatic driving collision target vehicle carrying platform, which comprises an assembly shell, a motor, a transmission mechanism, a backup brake, a suspension and wheels. When the power assembly is used, the motor outputs driving force to be transmitted to the wheels through the transmission mechanism to drive the wheels to rotate; thebackup brake is used for braking an output shaft of the motor, the top of the suspension supports the assembly shell, and when the assembly shell bears load changes, the suspension contracts or extends to drive the wheels to rotate upwards and downwards with the shell of the transmission mechanism as a swing arm and a rotating shaft of the motor as a swing arm rotation center. Compared with the prior art, the power assembly has the advantages of being small in size, stable and reliable in structure, stable and efficient in power and braking function, convenient to dissipate heat and good in heat dissipation effect.

Description

technical field [0001] The invention relates to the field of automatic driving, in particular to an ultra-thin power assembly for an automatic driving collision target vehicle carrying platform. Background technique [0002] The crash test of autonomous driving vehicles is generally used to detect the ability of the tested vehicle to perceive the surrounding environment, the ability to deal with emergencies, and the ability to cooperate and interact between vehicles. In order to ensure the safety of testers and equipment in the crash test, the crash target vehicle is made of soft materials such as foam or fabric, and has the ability to move autonomously and simulate the high-speed movement of a car in a real road environment. In the automatic driving collision test, the target vehicle is hit and crushed by the test vehicle at high speed when it is running at high speed. It must be ensured that the test vehicle will not be damaged or rolled over during the collision and crush...

Another example is the application publication number CN 111257014A "A Power Assembly for a Traffic Simulator Carrying Platform for Unmanned Driving Test". The output shaft is rigidly coupled, it is difficult to achieve coordination and synchronization with the output of the motor, the transmission generates heat and the efficiency is low; the motor lacks a cooling device, and the continuous working ability is poor
