Sealing performance detection device suitable for connection of skylight and car roof and detection method thereof

Abstract

The invention discloses a sealing performance detection device suitable for connection of a skylight and a car roof, the sealing performance detection device comprises a main body assembly and a pressurizing assembly, the main body assembly comprises a box body, a first plate body, a second plate body and a first water storage tank; the pressurizing assembly is mounted on one side of the main body assembly; the pressurizing assembly comprises a second water storage tank. By starting a first electric push rod, a piston rod of the first electric push rod drives a third plate body to move downwards in the second water storage tank, a circular plate body is driven to move upwards under elastic potential energy of a spring, and then the circular plate body is extruded by water pressure in the second water storage tank to move close to the third plate body; at the moment, the first electric push rod drives the third plate body to move upwards, water pressure above the third plate body extrudes the circular plate body to move downwards, and auxiliary water flows downwards into a spray head through a first circular through hole to be sprayed out, so that the purpose of pressurizing the water sprayed out of the circular plate body is achieved, and the device is used for simulating rainstorm weather; and the connection sealing performance of the detection skylight and the car roof is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile sunroofs, and in particular relates to a sealing performance detection device and a detection method suitable for connecting a sunroof and a vehicle roof. Background technique [0002] The car sunroof is installed on the roof, which can effectively circulate the air in the car and increase the entry of fresh air. At the same time, the car sunroof can also broaden the field of view and meet the shooting needs of mobile photography. When the car is used, the poor sealing of the sunroof will cause In case of water leakage on the roof in rainy days, causing unnecessary economic losses, test the tightness of the connection between the sunroof and the roof; [0003] When testing the seal between the existing sunroof and the roof, it is usually used to survey the working state of the sunroof motor by manual experience and observe with the naked eye, which is used to detect the airtightness of the sunr...

Problems solved by technology

[0003] When testing the seal between the existing sunroof and the roof, it is usually used to survey the working state of the sunroof motor by manual experience and observe with the naked eye, which is used to detect the airtightness of the sunroof and to test the airtightness by simulating the weather. When the pressure is insufficient, it is impossible to simulate the rainstorm for detection. Therefore, a leak detection device and detection method suitable for the connection between the sunroof and the roof are proposed.
