Problems solved by technology

At present, the equipment for durability testing of car doors in China has great limitations and unreliability due to the unclear test method; due to the high frequency of durability of car doors, the durability of the equipment itself is also assessed. If the equipment is not reliable, it cannot be tested. Effectively detect the reliability of the door system and the matching performance of related functional parts, and the test method for the durability of the revolving door system is also blank in China
[0003] Patent document CN02234888.3 discloses an automobile door opening and closing durability test bench, which only simulates the two basic actions of the door opening and closing, without completely evaluating the performance of each matching functional part, and has a complex structure and high production cost

Embodiment Construction

[0055] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0056] Since the door system includes door sheet metal assembly, electric door lock assembly, door hinge, limiter, inner handle, outer handle, glass regulator, sealing strip and other related functional components, the test method is set as follows:

[0057] Step 1: After the door is closed, activate the door lock insurance;

[0058] Step 2, activate the door lock and unlock the insurance;

[0059] The door locking insurance in the step 1 and the door unlocking insurance in the step 2 specifically include the following two types:

[0060] When the door is opened inside, perform the action of locking and unlocking the electric door lock in sequence, and then start the unlocking of the inside opening door in step 3. ...

Abstract

The invention relates to a durability testing method for a rotary vehicle door system and a durability testing device. The durability testing method includes the steps: starting safing for a vehicle door lock after a vehicle door is closed; removing safing for the vehicle door lock; and unlocking the vehicle door, opening the vehicle door and closing the vehicle door when the vehicle door is opened to the largest extent. The durability testing device comprises a vehicle door closing mechanism, an inward opening unlocking mechanism, an outward opening unlocking mechanism, a vehicle door unlocking protector, a vehicle door opening largest position buffering mechanism, a glass lifting controller, a door lock safing or safing removing controller and a microprocessor. By the aid of the durability testing device for the rotary vehicle door system, users' operation action of the rotary vehicle door and control of door opening and closing force can be simulated, so that reliability of the rotary vehicle door system and compatibility of relevant functional parts are effectively detected. The durability testing device has the advantages of fine universality, simple structure, simplicity and convenience in operation and high reliability and safety.

Description

technical field [0001] The invention relates to the technical field of automobile product testing, in particular to a durability test method and device for a revolving door system. Background technique [0002] With the development of the automobile industry, users have higher requirements on various aspects of automobiles, and the reliability, safety and comfort of automobiles have attracted more and more attention from people. The requirements for the reliability of the automobile door system and the matching of related functional parts are also getting higher and higher. The matching of the door system, the operating force of opening and closing the door, and the operating torque directly affect the comfort in ergonomics. At present, the equipment for durability testing of car doors in China has great limitations and unreliability due to the unclear test method; due to the high frequency of durability of car doors, the durability of the equipment itself is also assessed. ...
