Reliability and durability testing device and testing method of automobile electric tailgate system

Abstract

The present invention discloses an apparatus for testing the reliability and durability of an automotive electric tailgate system. The apparatus is provided with a test controller device, a simulatedkick device, and a kick sensor; and the test device is provided with a linear cylinder at the main driver position, and the extended end of the linear cylinder is matched with a switch button of the tailgate. The present invention also discloses a test method for the apparatus. By using the technical scheme of the present invention, the generalized and platformized design ideas are used as the guidance, the test cost can be reduced and the applicability of the system can be improved; the requirements for the reliability and durability of the automotive electric tailgate system meet the relevant national standards, and failure of the automotive electric tailgate system can be prevented; the apparatus for testing the reliability and durability of the automotive electric tailgate system has asimple structure, a low cost, strong versatility, and easy maintenance; the test method for the apparatus is easy to operate and highly reliable; the test cycle, the test frequency, and the number oftimes of tests of the apparatus can be adjusted and set according to actual requirements; and the mechanism can be flexibly mobile, and is convenient for application under different conditions and occasions.

Description

technical field [0001] The invention belongs to the technical field of automobile detection and relates to the testing technology of the tailgate of the automobile, including its testing equipment and testing process. More specifically, the present invention relates to a reliability and durability testing device for an electric tailgate system (kick induction) of an automobile. The invention also relates to a testing method adopted by the testing device. Background technique [0002] Automobile electric tailgate is one of the important components of the whole vehicle component system. The basic structure of the automobile electric tailgate is composed of two mandrel drive rods, and the drive rod is composed of an inner tube and an outer tube through the spindle drive. Wherein, a motor and a gear in the inner tube drive a threaded main shaft; the threaded main shaft moves on a threaded nut fixed inside the outer tube. The electric strut uses the electric spindle located in...

Problems solved by technology

[0005] For the electric tailgate assembly, the domestic industry does not specify detailed test methods, nor does it specify the test device. Parts manufacturers carry out test verification for each component, and major companies have different durability and reliability times for assembly verification. The number of cycles of reliability and durability test is 1×10 4 ~5×10 4 Between times, it is difficult to achieve by manual
