In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0027] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0028] The present utility model provides a pressing type power generation device based on lead titanate piezoelectric ceramics. By pressing the pressure member, the pressure member presses down the power generation member, and under the piezoelectric effect, the power generation member generates electric energy sufficient for the use of various low-power devices. The pressure member adopts a rigid structure to stably transfer the pressure. Please refer to Figures 1-4 , including: a support member 100, a power generation member 200 and a pressure member 300;

[0029] The support member 100 includes a barrel body 110 and a chute 120, and a chute 120 is provided on the inner wall of the top opening of the barrel body 110;

[0030] Among them, the barrel body 110 is a round barrel with an open top, and the chute 120 is a circular groove with a diameter larger than the inner diameter of the barrel body 110.

[0031] The power generating component 200 is arranged inside the barrel body 110. The power generating component 200 includes lead titanate piezoelectric ceramic sheets 210 and conductive components 220. The lead titanate piezoelectric ceramic sheets 210 are uniformly stacked inside the barrel body 110, and the conductive components 220 are respectively located at the top and bottom of the lead titanate piezoelectric ceramic sheets 210;

[0032] Among them, when pressure acts on the lead titanate piezoelectric ceramic sheets 210, under the piezoelectric effect, an electric current is generated between the lead titanate piezoelectric ceramic sheets 210.

[0033] The pressure component 300 is arranged on the sliding groove 120. The pressure component 300 includes a slider 310, a connecting column 320 and a pressing plate 330. The slider 310 is slidably connected to the sliding groove 120, and the bottom of the slider 310 is connected to the pressing plate 330 through the connecting column 320;

[0034] Among them, the slider 310, the connecting column 320 and the pressing plate 330 are of an integral rigid structure. When pressing down, the pressure can stably act on the lead titanate piezoelectric ceramic sheets 210.

[0035] Since an electric current needs to be generated when there is pressure, and no electric current is required when there is no pressure, and the pressure component 300 itself will press on the lead titanate piezoelectric ceramic sheets 210 under its own weight. Therefore, a return spring 400 is connected between the bottom of the sliding groove 120 and the bottom of the slider 310. In the natural state of the return spring 400, the pressure component 300 is separated from the power generating component 200, so that when pressing down, the pressure component 300 presses on the lead titanate piezoelectric ceramic sheets 210, and when releasing, the pressure component 300 is separated from the lead titanate piezoelectric ceramic sheets 210.

[0036] To facilitate the connection of wires, a wire hole is provided on the side wall of the barrel body 110, and the conductive component 220 extends to the outside of the barrel body 110 through the wire hole, and the conductive component 220 extending to the outer end can be connected to an external wire.

[0037] Anti-slip ridges are provided on the top of the slider 310 to prevent slipping when pressing.

[0038] During specific use, press the pressure component 300, the pressure component 300 presses down, so that the pressing plate 330 presses on the power generating component 200. Under the piezoelectric effect, an electric current is generated between the lead titanate piezoelectric ceramic sheets 210, and the electric current is transmitted to the external circuit through the conductive component 220. Release the pressure component 300, and the pressure component 300 rises under the rebounding action of the return spring 400, and the pressure component 300 is separated from the lead titanate piezoelectric ceramic sheets 210.

[0039] Although the present utility model has been described above with reference to the embodiments, various improvements can be made thereto and components thereof can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed by the present utility model can be combined with each other in any way, and the exhaustive description of these combinations is not given in this specification only for the sake of saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
