Vehicle window air pressure sealing system

Abstract

The invention discloses a vehicle window air pressure sealing system. The system comprises an assembly positioning lip side, air pressure hoses, a loop interface, a three-position three-way solenoid directional valve, a decompression valve, an air pump, a filter, an air pressure sensor, a vehicle speed sensor and a controller. The assembly positioning lip side is fixedly connected with a vehicle body, and the two air pressure hoses are fixed at the inner and outer sides of vehicle window glass; the two air pressure hoses are communicated through the loop interface and form a gas loop with thethree-position three-way solenoid directional valve, the decompression valve, the air pump and the filter; and the air pressure sensor, the vehicle speed sensor, the controller, the three-position three-way solenoid directional valve and the air pump form a control loop. The vehicle window air pressure sealing system has the advantages that signals of the air pressure sensor and vehicle speed sensor serve as input, the controller controls the three-position three-way solenoid directional valve and the air pump to work, and the internal pressure in the air pressure hoses is adjusted to ensure that the vehicle window glass always fits the air pressure hoses to prevent the noise from being transmitted into a vehicle; the elasticity and damping of the air pressure hoses reduce the vibration ofthe vehicle window glass and have the advantages of vibration and noise reduction.

Description

technical field [0001] The invention belongs to the technical field of automobile window sealing, in particular to an automobile window air pressure sealing system. Background technique [0002] There are sealing strips around the window glass of the car to play the role of waterproof, dustproof, isolation of external noise and vibration and noise reduction of the window glass. The rubber sealing strips and felts in the prior art mainly include the sealing strip substrate, the glass contact lip and the assembly fixing lip, which can maintain good sealing performance under normal circumstances, but it is difficult to achieve sufficient sealing performance in some special cases, resulting in The sound insulation effect is reduced, and the vibration noise of the window glass is obvious. For example: when the car is running at high speed, the external airflow disturbance stimulates the high-frequency vibration of the window glass to generate a lot of noise, and at the same time...

AI Technical Summary

Problems solved by technology

In order to solve the problem of the car's high-speed driving, passing through the tunnel and other special working conditions, as well as the hardening of the sealing system, the sealing effect is reduced, resulting in the isolation of external noise and the lack of vibration and noise reduction effect of the window glass
