Embodiment Construction

[0016] Specific embodiments of the present invention will be described in detail below in conjunction with technical solutions and accompanying drawings.

[0017] figure 1 Zhong is the currently commercialized built-in battery-powered wireless tire pressure monitoring device. The built-in tire pressure device needs to disassemble the tire and then replace it with a built-in tire pressure sensor at the valve core. The tire pressure sensor and the wireless transmission module are located inside the wheel hub.

[0018] figure 2 Shown is a schematic diagram of a tire pressure monitoring device jointly powered by a friction nanogenerator and a battery. The flexible friction nanogenerator is connected to a black module and attached to the side of the wheel hub.

[0019] Figure 5 The control circuit shown in will detect the battery energy. When the battery energy is sufficient, the triboelectric nanogenerator works but does not supply power to the battery. When the energy of t...

Abstract

A wireless tire pressure monitoring system powered by a friction nanometer generator and a battery in a hybrid mode comprises the friction nanometer generator, a pressure and temperature detection module, a sensor MCU, an RF module, the lithium battery, a switch control circuit and a voltage stabilizing circuit. The friction nanometer generator passes through the rectifier and then is connected to two ends of the super capacitor and the voltage stabilizing circuit in parallel; and the voltage stabilizing circuit and the battery supply power to the pressure and temperature detection module, the sensor MCU and the RF module which are connected in series through the switching circuit. The system is slightly modified on the basis of an existing commercial tire pressure monitoring device, the stability and the practicability are better, and the service life of the built-in tire pressure sensor can be effectively prolonged. The structure is smaller and simpler, and the market prospect is good.

Description

technical field [0001] The invention belongs to the technical field of automobile intelligent monitoring, and relates to a wireless tire pressure monitoring system powered by a friction nanometer generator and a battery. Background technique [0002] The tire pressure of the car plays an important role. The car tire pressure monitoring system is a kind of safety guarantee technology for the driver by installing electronic sensors in the tires to monitor the various conditions of the tires in real time. By monitoring the tire pressure, the tire can be alarmed in time when there are signs of danger in the tire, and the driver can be reminded to take corresponding measures. Insufficient tire pressure will lead to reduced tire life, so keeping the tire pressure in the normal range can effectively prolong tire life. When the tire pressure is too low, it will increase fuel consumption, so monitoring tire pressure can help reduce fuel consumption. When the tire pressure is insuff...
