Problems solved by technology

That is to say, 5,000 times of long-lasting tests are required, but there is no detailed test method and no clear test device. Manual testing is very tedious work. Some of the major enterprise standards even require 30,000 times of opening and locking. Experiments, which are difficult to achieve by hand

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an automobile safety belt buckle reliability test device and a test method thereof. Background technique [0002] Nowadays, cars have gradually become the means of transportation that people need daily. Car seat belts are one of the important parts of the vehicle safety component system. When a vehicle has a road traffic accident, car seat belts play a very important role in protecting the occupants of the car. .In order to achieve a good protective effect of the seat belt, the strength design and guarantee of the seat belt assembly are the key. Each component of the automobile safety belt assembly must have sufficient strength to prevent the safety belt assembly from breaking or failing in the event of a vehicle collision. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior ar...
