Abstract

The invention aims to provide a test device for the durability of a car door retainer, which has convenient use, good commonality and low cost and comprises a simulation post and a simulation door hinged on the simulation post. Particularly, the simulation post is fixed on a base; the support end of the car door retainer to be tested is fixed on the simulation post, and the retainer box end of the car door retainer to be tested is fixed on the simulation door; the simulation door is hinged on a piston rod of an air cylinder with an end part movably fixed on the base, and the air cylinder is controlled by a PLC (Programmable logic Controller) through an electromagnetic valve. The test device for the durability of the car door retainer utilizes pneumatic components with high accuracy to be matched with the program control of the PLC so that a test process is accurately controlled, and tests of car door retainers of various car models in various conditions can be satisfied. The whole test device has simple structure, low cost, easy operation, convenient maintenance and high reliability.

Description

technical field [0001] The invention relates to a test device for automobile parts, in particular to a test device for the durability of a car door stopper. Background technique [0002] The door stopper of a car can limit the opening angle of the door and protect the door from accidental damage, especially when the door is opened with the wind. It is an important part of the car, and its durability directly determines its service life. It directly affects its safety, so it is necessary to test the durability of the door stopper. At present, the test of the durability of the door stopper has not been reported, and the domestic special test equipment in this respect is still blank. Contents of the invention [0003] The object of the present invention is to provide a device for testing the durability of a door stopper which is convenient to use, good in versatility and low in cost. [0004] The vehicle door stopper durability testing device of the present invention compri...
