[0002] Currently, when testing a car sunroof, the sunroof is open and affected by wind, generating wind loads. Therefore, testing the wind load performance of the sunroof is an important step in ensuring the performance of the sunroof. Currently, when checking the wind load of a car sunroof, the sunroof is usually opened and closed, and a weight is placed on the sunroof.

[0003] For example, publication number CN106441829A, published on February 22, 2017, disclosed a wind-load test bench for automobile sunroofs. The bench comprises a base, a placement platform disposed on the base, a fixing device disposed on the placement platform, a wind-load suction cup disposed above the placement platform, a load disposed at the rear of the placement platform, the wind-load suction cup connected to the load via a connecting rope, the connecting rope being steered by a steering device above the wind-load suction cup, and an opening and closing device disposed on the placement platform. However, the aforementioned wind-load test bench, when in use, is not practical due to the fixed position of the pulley, which prevents the wind-load suction cup from being easily moved on the sunroof glass. Consequently, it is not possible to test sunroof glass of different specifications. Summary of the Invention
