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...
