Abstract

The invention discloses an inflation valve device of an electric vehicle. The inflation valve device comprises a device main body, wherein an air filling hole is formed in the top end of the device main body; an air exhausting hole is formed in the bottom end of the device main body; the bottom end of the device main body is wrapped with a rubber sleeve; the outer surface of the rubber sleeve is sleeved with a protection cover; the upper surface of the rubber sleeve is covered with a soft rubber pad; fixed piles are welded on the inner wall of the top end of the device main body; the right sides of the fixed piles are connected with connection piles through rotating shafts; protection plates are welded on the top ends of the connection piles; the inner side of the device main body is connected with an inflation valve core through threads; the outer surface of the inflation valve core is sleeved with a sealing ring; and the outer surface of the sealing ring is embedded in the inner wallof the device main body. Through the inflation valve device of the electric vehicle, the protection performance of a connection part between the inflation valve device and a wheel hub can be improved; and the top end of the inflation valve device can be automatically protected.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a valve device of an electric vehicle. Background technique [0002] The valve device, also known as the valve, is an important part of the electric vehicle and is mainly installed on the wheel hub. [0003] When the existing valve device is in use, there is no sealing protection structure at the connection between the valve device and the wheel hub, and the air pressure inside the wheel hub is directly used to resist the valve device to achieve the sealing effect. When the car is in a static state for a long time, the gas in the wheel hub slowly leaks out , the gap between the valve device and the wheel hub will become larger, so that dust and rainwater will enter the wheel hub through the gap, and the top of the existing valve device is protected by the valve cap. When the valve cap is lost, the valve device cannot be adjusted. Therefore, it is urgent to design a valve devi...
