A lifting device for testing the wind load mechanism of the sunroof glass of the automobile sunroof assembly

Abstract

The invention discloses a lifting device for testing a wind load mechanism of a piece of skylight glass of an automobile skylight assembly. The lifting device comprises a framework, the framework comprises a bottom framework and a side framework arranged at one end of the bottom framework, a top framework is arranged at the top end of the side framework, a main control box is arranged at one side of the side framework, the top framework is provided with a pair of transverse slide bars, a cross plate is arranged between the two slide bars through a slide block, and a lifting mechanism is arranged at the side end of the cross plate; a load sensor is arranged at the side end of the lifting mechanism; the lifting device comprises an adjusting fixing mechanism arranged at the side end of the cross plate and a servo electric cylinder firmly arranged on the adjusting fixing mechanism, and the adjusting fixing mechanism comprises a pair of adjusting screws vertically arranged at the side end of the cross plate. The lifting device for testing the wind load mechanism of the skylight glass of the automobile skylight assembly uses a screw rod of the servo electric cylinder to form lifting force for the skylight glass, and meanwhile, the main control box is capable of monitoring the change of the lifting force of the servo electric cylinder, and therefore, the wind load bearing test for the skylight is precise, and the error is very small.

Description

technical field [0001] The invention relates to the field of automobile sunroof production, in particular to a lifting device for testing the wind load mechanism of the sunroof glass of the automobile sunroof assembly. Background technique [0002] 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. The sunroof assembly includes the sunroof glass and the roof. The bottom of the roof is four feet downward. When the car is running, at a certain speed, the pressure difference formed inside and outside the sunroof will make it difficult to open the sunroof. Therefore, it is necessary to test the ability of the skylight to withstand wind loads. The existing testing device is not accurate enough to test the lifting force of the skylight glass, which easily leads to errors and cannot accurately measure the bearing capacity of the skylig...

Problems solved by technology

The sunroof assembly includes the sunroof glass and the roof. The bottom of the roof is four feet downward. When the car is running, at a certain speed, the pressure difference formed inside and outside the sunroof will make it difficult to open the sunroof. Therefore, it is necessary to test the ability of the skylight to withstand wind load. The existing test device is not accurate enough to test the lifting force of the skylight glass, which may easily lead to errors and cannot accurately measure the bearing capacity of the skylight glass at a certain wind speed.
