Problems solved by technology

However, in actual use, if the user directly presses the elastic piezoelectric ceramic sheet, the pressing speed is relatively slow, and when different users operate, the pressing speed is different, which will cause that if the user presses slowly, Then the power generated by it is very limited.

Embodiment 1

[0129] Embodiment 1 of the present invention provides a piezoelectric ceramic power generation device, such as Figure 4 As shown, the device includes an upper shell, a lower shell, an elastic piezoelectric ceramic sheet, and an elastic sheet. In order to ensure the excellent resilience characteristics of the elastic sheet, in the embodiment of the present invention, the elastic sheet can be realized by using a pot sheet. :

[0130] The elastic piezoelectric ceramic sheet is fixed on the base of the lower shell, wherein, after the elastic piezoelectric ceramic sheet is fixed, the gap between the bottom plate of the lower shell and the elastic piezoelectric ceramic sheet provides all Said elastic piezoelectric ceramic sheet power generation action space. In the embodiment of the present invention, the pedestal is usually arranged in the designated area of ​​the elastic piezoelectric ceramic sheet substrate. Preferably, a three-point layout is preferred, because the fewer layout po...

Embodiment 2

[0140] In Embodiment 1, for example, the rapid deformation characteristics of the elastic sheet are used to enable the piezoelectric sheet to deform rapidly, but since the elastic sheet also contacts the piezoelectric ceramic before deformation, the force applied by the user will also act on the elastic sheet before it crosses the critical point. On the elastic piezoelectric ceramic sheet, the elastic piezoelectric ceramic sheet will also have a certain deformation at this time. Because this part of the deformation is slowly pressed by the user, its power generation is very small, that is, this part of the deformation has a relatively small contribution to the power generation. In order to solve the potential deficiencies in embodiment 1, the embodiment of the present invention also provides a piezoelectric ceramic power generation device, such as Picture 11 As shown, the device includes an upper shell, a lower shell, an elastic piezoelectric ceramic sheet, a transition device ...

Embodiment 3

[0150] Each of the above embodiments uses shrapnel (for example: conventional pot slices) to be specifically implemented as a "conversion device". Although the structure is simple and the cost is relatively low, there are life problems similar to pot slices, and the pot slices It is relatively thin, and it is troublesome to install and fix other components. The embodiment of the present invention provides another solution based on the "conversion device" of different implementation forms, that is, the use of the adsorption of the magnet to achieve the function of the conversion device.

[0151] Such as Figure 15 As shown, the device proposed in the embodiment of the present invention includes an upper shell, a lower shell, an elastic piezoelectric ceramic sheet, a driver, a first magnet group and a second magnet group, specifically:

[0152] The elastic piezoelectric ceramic sheet is fixed on the first base of the lower shell, wherein, after the elastic piezoelectric ceramic sheet...

Abstract

The invention relates to the technical field of piezoelectric ceramic power generation, and provides a piezoelectric ceramic power generation method and device. The device comprises an elastic piezoelectric ceramic piece, a driving mechanism and a switching device, wherein when an external acting force is applied to the driving mechanism, the driving mechanism transfers the external acting force to the switching device; when the force applied to the switching device is less than a first preset force, the switching device does not act or is deformed within a preset range; when the force appliedto the switching device is more than the first preset force, the switching device acts quickly to impact the elastic piezoelectric ceramic piece, and thus the elastic piezoelectric ceramic piece generates electric energy. According to the device and method provided by the invention, the switching device with a first state and a second state is used, the effect of setting the driving threshold forthe external acting force is achieved, the corresponding quick deformation speed is also transferred to the elastic piezoelectric ceramic piece, and thus the more power is generated.

Description

【Technical Field】 [0001] The invention relates to the technical field of piezoelectric ceramic power generation, in particular to a piezoelectric ceramic power generation device and method. 【Background technique】 [0002] With the development of technology, more and more electronic products that require batteries have appeared on the market. However, used batteries can cause serious pollution to the environment. Therefore, developing a new way to replace batteries has become an urgent need to protect the environment and human life and health. [0003] Piezoelectric ceramic materials have a unique piezoelectric effect, which can convert mechanical energy into electrical energy. Under the action of external vibration or impact, the piezoelectric ceramics deform and output electric charge. Under continuous vibration conditions, piezoelectric ceramics will also continuously output electrical energy. Technology applied to life through many links such as energy conversion, rectificat...
