Magnetic powder tire monitor

Abstract

The invention relates to a magnetic powder tire monitor. The magnetic powder tire monitor is mounted into a wheel hub of a wheel; the wheel comprises an outer tire, an inner tire and the wheel hub; the magnetic powder tire monitor comprises a conductive ring, a track ring and a magnetic field sensor; the conductive ring and the track ring are coaxially mounted inside the wheel hub; the magnetic field sensor is mounted on the track ring in a sliding manner; the magnetic field sensor comprises a magnetic sensing end, a processor and a discharge end; the discharge end is in electrical contact with the conductive ring; the conductive ring is electrically connected with a display inside a vehicle body; after being inflated, the inner tire is cylindrical; along the circumferential direction of the inner tire, the inner tire can be dissected into two concentric circular rings; the two circular rings are an inner circular ring and an outer circular ring according to inside and outside positions respectively; the inner wall of the outer circular ring of the inner tire is uniformly coated with magnetic powder. The magnetic powder tire monitor is exquisite in structure and novel in principle,and can accurately monitor the pressure condition of each tire so as to effectively prevent occurrence of tire burst.

Description

technical field [0001] The invention relates to a vehicle monitoring device, in particular to a tire monitor. Background technique [0002] After entering the summer, the air pressure of the tires has become a very concerned part of most drivers, because it is very easy to induce a tire blowout in high temperature weather; in order to prevent this danger, it is especially necessary to monitor the status of the tires at any time; The tool is "Tire Pressure Monitoring System", namely "TPMS", which can monitor the tire pressure in real time. It monitors the driving condition of the tire through the change of the tire speed; The rotation speed of this tire and the adjacent tire will change, and the damaged tire can be compared through the change; but this system has a disadvantage, that is, when the pressure of two tires in the same row decreases at the same time, the monitoring system cannot monitor Therefore, the "TPMS" has certain technical loopholes.
