A device for tire pressure monitoring

Abstract

A device for tire pressure monitoring belongs to the technical field of automobile parts; it includes a tire hub, a limit device and a detection device, wherein an inner ring is formed on the surface of the tire hub, and a through hole is formed on the surface of the inner ring, The through hole is arranged obliquely to the inner side of the tire hub, the limiting device is arranged on both sides of the through hole, and one end of the detection device is inserted into the interior of the limiting device; The detection device can be clamped inside the limit device, and the top of the detection device can protect the detection device to avoid damage to the detection device after the car tires run out of air. Pressure through holes are opened on the left and right sides of the power box to avoid External pressure will punch the box cover, and at the same time, there is an installation gap inside the limit device, and the installation gap and the maintenance cover on the detection device correspond to each other, so that the limit device will not affect the power box when it is disassembled.

Description

technical field [0001] The invention belongs to the technical field of automobile parts, and in particular relates to a device for monitoring tire pressure. Background technique [0002] Tire pressure monitoring system is referred to as "TPMS". This technology can automatically monitor various conditions of the tire in real time by recording the tire speed or electronic sensors installed in the tire, which can provide effective safety guarantee for driving. [0003] The built-in pressure detection parts of the tire pressure detection device are inserted into the rubber ring to perform pressure detection. However, if the car leaks and the tire cannot be replaced, the internal pressure detection device will be damaged, so it needs to be replaced. In this way, the cost of replacement is too high, and at the same time, the valve core head of the part is integrated with the internal parts, and it is more troublesome to replace. SUMMARY OF THE INVENTION [0004] The present in...

AI Technical Summary

Problems solved by technology

[0003] The built-in pressure detection part of the tire pressure detection device is plugged into the rubber ring for pressure detection, but if the car leaks and the car cannot replace the tire, it will damage the internal pressure detection device and need to be replaced. In this way, the cost of replacement is too high. At the same time, the first part of the valve core of the part is integrated with the internal parts, and it is more troublesome to replace it.
