[0024] refer to Figure 1-5 This embodiment provides a piezoelectric ceramic power generation remote controller, comprising: a housing, a bracket disposed in the housing, and a piezoelectric ceramic power generation component; the housing is divided into a cover 1 and a base 2;

[0025] The bracket includes a first sub-bracket 3 and a second sub-bracket 4, the first sub-bracket 3 and the second sub-bracket 4 are pivotally connected to form an X-shaped structure, and one end of the first sub-bracket 3 and the second sub-bracket located on the opposite sides of the X-shaped structure is a fixed end and is respectively fixed to the base 2;

[0026] The other end of the first sub-bracket 3 and the second sub-bracket 4 is a movable end, the movable end of the first sub-bracket 3 is linked to the button module arranged on the face cover 1, and the piezoelectric ceramic power generation component is arranged between the movable end of the second sub-bracket 4 and the fixed end of the first sub-bracket 3.

[0027] Specifically, the key module includes a key 5 and a PCB board 6. The piezoelectric ceramic power generation component includes a piezoelectric sheet support 7, a support layer 13, a piezoelectric sheet 8, a pot piece 9, and an elastic member; the piezoelectric sheet support 7, the support layer 13, the piezoelectric sheet 8, and the pot piece 9 are assembled into a power generation component and abut against the base 2, and the elastic member is arranged between the power generation component and the cover 1.

[0028] In this embodiment, the elastic member includes a mass block 10, a spring 11 and a spring upper cover 12; the spring 11 is arranged between the spring upper cover 12 and the mass block 10, and the mass block 10 is in contact with the power generation component.

[0029] With the above arrangement, when the user presses the button 5 on the button module, the bracket sinks and drives the piezoelectric sheet bracket 7 in the piezoelectric ceramic power generation component to tilt upward, and is squeezed with the spring 11 fixed on the cover 1. At this time, the piezoelectric sheet 8 and the pot sheet 9 fixed on the piezoelectric sheet bracket 7 are driven to tilt upward at the same time. That is, when the button 5 is pressed, the bracket drives the mass block 10 of the piezoelectric ceramic power generation component to touch the pot sheet 9, causing the pot sheet 9 to deform instantly, pressing the middle part of the piezoelectric sheet 8 to produce a slight deformation; after the piezoelectric sheet 8 is deformed, a weak current will be generated, and then the current will be transmitted to the PCB board 6 through the conductive wires on the piezoelectric sheet 8, thereby providing electrical energy to the PCB board 6.

[0030] When the pressing is released, the spring 11 rebounds to restore the bracket to its original position.

The side wall of the receiving cavity is provided with a third clamping claw 23, and the piezoelectric sheet bracket 7 is provided with a third clamping column 71 that cooperates with the third clamping claw 23.

[0032] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
