Abstract

The invention provides a tire air pressure detection device based on the wireless charging technology. A pressure sensor is connected with a CPU circuit. The CPU circuit is connected with a signal transmitting antenna through a signal transmitting circuit. An electric energy receiving coil is connected with the CPU circuit through an electric energy receiving circuit. A signal receiving antenna is connected with a system control circuit through a signal receiving circuit. The system control circuit is connected with an electric energy transmitting coil though an electric energy transmitting circuit and further connected with an alarm circuit. In this way, online real-time detection of tire air pressure is realized, a power source does not need to be installed in a tire, and the circuits are simple.

Description

technical field [0001] The invention relates to a vehicle safety guarantee technology, in particular to a tire pressure detection device based on wireless charging technology. 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 object of the present invention is to provide a tire air pressure detection device based on wireless charging technology, which uses a power transmitting circuit, a power receiving circuit and a pressure sensor for detection. The tire air pressure detection device does not need to install a power supply in the tire, has a simple...
