Abstract

The invention provides a resonant magnetic coupling tire air pressure detection device. The upper static contact and the lower static contact of the button switch are connected to the resonant circuit through wires, the resonant circuit is connected to the secondary coil, and the primary coil is connected to the comparator through the sinusoidal AC circuit. The circuit is connected, the comparator circuit is connected with the system control circuit, and the system control circuit is also connected with the alarm circuit. The button switch is installed between the car hub and the inner tire, the secondary coil is installed at the lower end of the wheel shaft, the primary coil is installed on the brake hub, and corresponds to the position of the secondary coil on the wheel shaft, and the wire is inlaid and installed on the wheel shaft inside. Through the above-mentioned setting, the online real-time detection of the tire pressure is realized, and there is no need to install a power supply in the tire, the circuit is simple, and the installation is convenient.

Description

technical field [0001] The invention relates to a vehicle safety assurance technology, in particular to a resonant magnetic coupling tire air pressure detection device. Background technique [0002] During the running of the vehicle, too low or too high tire pressure will affect the safety of the vehicle, so it is very necessary to develop an online real-time tire pressure detection device. Existing tire air pressure detection device adopts wireless transceiving type or electromagnetic type. Its disadvantage is that the circuit structure is complicated, and the battery needs to be replaced frequently. Contents of the invention [0003] The purpose of the present invention is to provide a resonant magnetic coupling tire air pressure detection device, which uses a secondary coil, a primary coil, a button switch and a resonant circuit for detection. The tire air pressure detection device does not need to install a power supply in the tire, has a simple circuit and is easy t...
