Most wireless mice adopt disposable dry batteries for power supply, and the dry batteries have the problems of limited battery capacity, short service life, incapability of recycling and the like. In order to solve the problem of the mouse battery, researchers develop a rechargeable battery, and although the rechargeable battery relieves the pollution of the battery to a certain extent, the rechargeable battery is high in price and still needs to be charged frequently, so that the problem of power supply of the mouse cannot be solved fundamentally.
The mouse can generate micro energy in various forms during the use process, such as: pressure generated by pressing the mouse by a finger, mechanical movement force generated by shaking the mouse or sliding the pulley, and the like. The invention patent of a piezoelectric self-powered wireless mouse (application publication number: CN107741792A) utilizes a cantilever beam type piezoelectric energy harvester to recover the pressure stress of a pressed mouse, but the micro-energy collection efficiency is lower, so that the power supply power is insufficient. In the utility model, a wireless mouse self-power supply device based on electromagnetic induction energy collection (No. CN204496455U) utilizes a small generator to recover mechanical motion force generated by the rolling of a pulley, but only adopts a power generation device, so that the collection efficiency of micro energy is low, the pulley is not commonly used in practical use, and the electric energy generated by the power generation device is not enough to realize the self-power supply of the mouse. At present, a micro-energy collection power generation device applied to a mouse is developed, but the problems of low micro-energy collection efficiency and insufficient power supply power still exist, and the power consumption requirement of the mouse is difficult to meet.

Detailed Description
The invention will now be described in more detail by way of example with reference to the accompanying drawings in which:
referring to fig. 1-4, the mouse comprises a mouse shell 1, an electromagnetic power generation device 2, a piezoelectric power generation device 3 and an energy storage module 4. The electromagnetic power generation device 2 and the piezoelectric power generation device 3 together form a composite power generation device.
As shown in fig. 3, the dual vibrating piezoelectric cantilever 32 and the spring type piezoelectric cantilever 33 together form a piezoelectric cantilever with a piezoelectric layer.
The mouse case 1 includes a guide rail 11, a pulley 12, a fixing plate 13, and a pressing rod 14. The guide rail 11 is connected to the electromagnetic power generator 2, and the fixing plate 13 is connected to the piezoelectric power generator 3.
The electromagnetic power generation device 2 and the piezoelectric power generation device 3 together form a composite power generation device. The electromagnetic generating device 2 is composed of a spring 21, a magnetic block a22 and a coil 23, wherein the magnetic block a22 is fixedly connected inside the guide rail 11 through the spring 21, the coil 23 is wound outside the guide rail 11, and the electromagnetic generating device 2 is connected with the rectifying circuit 42 through a lead. The piezoelectric power generation device 3 is composed of a magnetic block b31, a double-vibration piezoelectric cantilever beam 32, a spring-type piezoelectric cantilever beam 33 and a mass block 34, wherein the mass block 34 is fixed at the free end of the spring-type piezoelectric cantilever beam 33, the magnetic block b31 is fixed at one end of the double-vibration piezoelectric cantilever beam 32, the other end of the double-vibration piezoelectric cantilever beam 32 is fixed on the fixing plate 13, and the piezoelectric power generation device 3 is connected with the rectifying circuit 42 through a lead.
The energy storage module 4 comprises a rechargeable lithium battery 41 and a rectifying circuit 42, the rectifying circuit 42 is arranged below the rechargeable lithium battery 41 and connected with the rechargeable lithium battery 41 through a lead, and the energy storage module 4 is fixed on the fixing plate 13.
The working process of generating electric energy in the invention is as follows: for the piezoelectric power generation device 3, when a user presses a left key or a right key of the mouse, the pressing force of a finger causes the pressing rod 14 to drive the magnetic block b31 to move downwards, at this time, the dual-vibration piezoelectric cantilever beam 32 and the spring-type piezoelectric cantilever beam 33 deform, and the mass block 34 can increase the inertia of the spring-type piezoelectric cantilever beam 33 and increase the vibration amplitude. When the user releases the mouse button, the dual vibrating type piezoelectric cantilever 32 and the spring type piezoelectric cantilever 33 vibrate to restore their original states, thereby generating a current. For the electromagnetic power generation device 2, when the magnetic block b31 moves up and down, the magnetic block a22 is displaced by the generated electromagnetic force, and the displacement of the magnetic block a22 drives the spring 21 to deform. Under the action of electromagnetic force and spring force, the magnetic block a22 reciprocates in the guide rail 11, so that the coil 23 cuts the magnetic induction line back and forth to generate current. The currents generated by the two power generation devices are rectified by the rectifying circuit 42 and then stored in the rechargeable lithium battery 41 to supply power for the mouse.
