Abstract

The invention provides a test bed for automobile doors. The test bed comprises a mechanical actuator mechanism, an electric control system and a sensing unit respectively coupled to the mechanical actuator and the electric control system. The mechanical actuator mechanism can be arranged inside an automobile and comprises an attachment mechanism, a transmission mechanism, a fixed bracket, a lifting platform and a servo motor adapted to drive the transmission mechanism. The attachment mechanism is attached to an automobile door. One end of the transmission mechanism is coupled to the attachment mechanism. The other end of the transmission mechanism is coupled to the servo motor. The sensing unit comprises an angle sensor, a force sensor and a speed detection unit fixed on the surface of the automobile door. According to the technical scheme of the invention, the test bed for automobile doors occupies a small space, and is easy in installation and strong in flexibility. During the test process, the loss of a to-be-tested automobile door and a testing mechanism is effectively reduced.

Description

technical field [0001] The invention relates to the field of testing of complete automobiles and components, in particular to an automobile door test bench. Background technique [0002] In the auto parts system, the car door is one of the main parts of the car body, providing the passage for the driver and passengers to enter and exit the vehicle. Automobile door components mainly include door hinges, door opening limiters, door lock mechanisms, etc. The action of opening and closing the car door mainly includes five steps of unlocking, unlocking, opening the door, closing the door and closing the lock. Because the car door has a durable time limit, exceeding this time limit will cause the car to be a safety hazard. Therefore, in order to test the durability of the car door and produce door components that meet the requirements, it is very important to develop a practical and highly reliable car door test bench. [0003] At present, most of the automobile door test benche...
