The invention discloses a magnetic toggle-type piezoelectric-electromagnetic composite generator based on rotational movements of wheels so as to solve problems such as short service life, narrow energy harvesting frequency bandwidth and small output power of the existing tire pressure sensor energy supply device. The magnetic toggle-type piezoelectric-electromagnetic composite generator comprisesfour parts such as a driving assembly, a power generation assembly, an electromagnetic power generation assembly and a shell, wherein the driving assembly is fixed in the shell, the power generationassembly is fixed on the shell through threaded connection, and the electromagnetic power generation assembly is bonded inside the shell. The magnetic toggle-type piezoelectric-electromagnetic composite generator generates a nonlinear stiffness effect by utilizing a nonlinear force between magnets, and can expand the energy harvesting frequency bandwidth of a piezoelectric component. Non-contact characteristics of the acting force between the magnets are utilized in the invention, so that the wear degree of the device can be reduced, and the service life of the device is prolonged. The outputpower of the device is increased according to a principle of compositing an electromagnetic induction phenomenon and a direct piezoelectric effect, so that the magnetic toggle-type piezoelectric-electromagnetic composite generator has wide application prospects in the technical field of vibration energy harvesting.
Description
technical field [0001] The invention relates to a magnetically driven piezoelectric-electromagnetic composite generator based on the rotational motion of a wheel, and belongs to the technical field of vibration energy capture. Background technique [0002] With the development of highways and the continuous improvement of automobile performance, the driving speed of automobiles is getting faster and faster, especially the rapid increase of car ownership, traffic is becoming more and more congested, and accidents are more frequent, so the safety of automobiles has become particularly important . Abnormal tire pressure can easily lead to accidents. In vicious traffic accidents, the proportion of traffic accidents caused by tire blowouts is very high, and insufficient tire pressure is one of the important causes of tire blowouts, which illustrates the importance of tire pressure monitoring systems. The current power supply method for tire pressure sensors is mainly chemical b...
