Control switch for vehicle body gas source

Abstract

The invention discloses a control switch for a vehicle body gas source. The control switch comprises a shell and a pressing cover installed at the top of the shell. A gas inlet cavity and an exhaust cavity are formed in the shell, the gas inlet cavity is provided with a gas inlet for introducing the gas source, and the exhaust cavity is provided with a gas outlet for discharging gas; at least twoindependently arranged gas path channels for communicating the gas inlet cavity with the exhaust cavity are also arranged in the shell; gas nozzles which are communicated with each gas path channel and extend out of the shell are also arranged in the shell; a gas inlet valve assembly for simultaneously communicating or blocking the gas inlet and all the gas path channels is arranged in the gas inlet cavity; an exhaust valve assembly for simultaneously communicating or blocking the gas outlet and all the gas path channels is arranged in the exhaust cavity; and a gas inlet thimble structure forcontrolling the gas inlet valve assembly and an exhaust thimble structure for controlling the exhaust valve assembly are arranged between the pressing cover and the shell. According to the control switch for the vehicle body gas source, equal-air-pressure inflation, exhaust and pressure maintaining in inflated bags are realized, so that no air flow exist among the air bags, and the comfort requirements of two or more pairs of side wing supporting air bags are ensured.

Description

technical field [0001] The present disclosure generally relates to the technical field of switches, in particular to a control switch for vehicle body air source. Background technique [0002] The existing side wing support switch that provides air source on the body, one switch controls one air path, shares one air nozzle, and the two side air bags are connected. When one side is stressed, since the two air bags are Collusion, at this time will cause the gas on the stressed side to be exhausted to the non-stressed side, resulting in the loss of the supporting effect on the side that needs wing support. Contents of the invention [0003] In view of the above defects or deficiencies in the prior art, it is desired to provide a control switch for vehicle body air source that can solve the above technical problems. [0004] In the first aspect, the present application provides a control switch for vehicle body air source, which includes a housing and a pressing cover install...
