Universal tire pressure monitoring system maintenance inflating valve and tire pressure monitoring system inflating valve

Abstract

The invention provides a universal tire pressure monitoring system maintenance inflating valve. The universal tire pressure monitoring system maintenance inflating valve comprises a maintenance inflating valve body and a valve core of the maintenance inflating valve, wherein the maintenance inflating valve body is provided with a connection section; the connection section is screwed into a residual part obtained by removing one section of a tire pressure monitoring system inflating valve body to be in threaded connection with the front part of the residual part; the maintenance inflating valve body is provided with a first sealing ring for sealing the connection part between the maintenance inflating valve and the residual part of the tire pressure monitoring system inflating valve body; the length of the maintenance inflating valve body is 32-40mm; a sealing structure is arranged between the maintenance inflating valve body and the valve core of the maintenance inflating valve so as to separate front and back spaces in the maintenance inflating valve. According to the tire pressure monitoring system maintenance inflating valve, the tire pressure monitoring system inflating valve is maintained to be recovered so that an electronic module connected with the tire pressure monitoring system inflating valve does not need to be scraped, thus the waste is reduced and the cost is lowered.

Description

technical field [0001] The present invention relates to the field of TPMS valves, and in particular to service valves for these valves. Background technique [0002] At present, motor vehicles, especially passenger cars, are generally equipped with tire pressure monitoring systems (TPMS). TPMS is composed of two parts, the electronic module and the valve, among which the electronic module and the valve body of most models are integrally designed (nozzle body type), that is, the valve body is used as an embedded part when the plastic shell of the electronic module is injected into the design. Parts injection, the difference from the assembled TPMS is that the electronic module and the valve are not disassembled. The designed service life of the electronic module is 5 years and 100,000 kilometers, and the core cavity at the front of the valve is exposed to the outside of the rim, which is affected by different use environments and frequently inflated and deflated until its se...

Problems solved by technology

The design service life of the electronic module is 5 years and 100,000 kilometers, and the core cavity at the front of the valve is exposed to the outside of the rim, which is affected by different use environments and frequently inflated and deflated until its service life is much lower than that of the electronic module.

In this way, when the core cavity at the front of the valve is partially damaged, the high-value electronic module is often scrapped together with the valve.
