technical field

The invention relates to the technical field related to automobile sunroofs, in particular to a device and method for detecting the durability of opening and closing of automobile sunroofs.

Background technique

The car sunroof is installed on the roof of the car, which can effectively circulate the air in the car, increase the entry of fresh air, and bring healthy and comfortable enjoyment to the car owner. At the same time, car windows can also broaden the field of vision, and are often used for shooting needs of mobile photography. Car sunroofs can be roughly divided into: sliding outside, built-in, built-in and turned-out, panoramic and curtain. It is mainly installed on commercial SUVs, sedans and other vehicles. However, the current automobile market has exposed many problems that the sunroof is difficult to open and close. The long-term operation of the car sunroof assembly can easily lead to problems such as abnormal noise, looseness or sticking. It is found that the failure rate of the sunroof assembly is high, so it is necessary In the process of component inspection, the inspection of the sunroof is strengthened, especially the durability test.
