Durability test bed for automobile door

Abstract

The invention provides a durability test bed for an automobile door and belongs to the field of measuring techniques. The durability test bed solves the problem that an existing test bed device can only detect the opening and closing frequency when an automobile door hinge or an automobile door lock reach a scrap state. The durability test bed for the automobile door comprises an upper computer, a force sensor, a base plate and a swing arm, wherein one end of the swing arm is hinged to the base plate provided with a cylinder capable of driving the swing arm to swing, and the other end of the swing arm is connected with a push-pull component; a cylinder piston rod is connected with the swing arm through the force sensor; the part where the swing arm and the base plate are hinged is provided with an angle sensor capable of detecting the size of swinging angle of the swing arm; the angle sensor and the force sensor are both in electric connection with the upper computer. In the durability test bed for the automobile door, the angle sensor and the force sensor are installed; test frequency, force and speed are controlled, adjusted and recorded through the upper computer and a PLC so as to be analyzed and determined by testers and designers, and meanwhile the durability test bed is capable of outputting and printing test report data.

Description

technical field [0001] The invention belongs to the technical field of measurement, and relates to a durability measurement, in particular to an automobile door durability test bench. Background technique [0002] Automobile originally refers to a transport vehicle powered by combustible gas, and also refers to a vehicle driven by its own equipment. Car doors can be divided into the following types according to their opening methods: forward-opening car doors, reverse-opening car doors, horizontally movable car doors, lift-up car doors and folding car doors. Even when the car is running, the sliding door can still be closed by the pressure of the airflow, which is relatively safe, and it is convenient for the driver to observe backward when reversing, so it is widely used; especially in cars. [0003] The front edge of the side-opening type car door is connected with the vehicle body through a hinge, and a lock is arranged between the rear edge and the vehicle body. In ord...

AI Technical Summary

Problems solved by technology

Although the device can detect the number of opening and closing times when the door hinge or door lock reaches the scrapped state, this value is only a limit value, which cannot reflect the state change of the door hinge and door lock during the detection process; it is not conducive to the analysis and improvement of the designer
