Embodiment Construction

[0015] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0016] combine Figure 1-3 , the present invention includes a mouse housing 1, a mouse wheel 2, a micro-energy collection device and an energy storage device.

[0017] The mouse housing 1 is composed of a fixed plate 3 and a cylindrical hole 4 , both of which are connected to the bottom of the mouse housing 1 .

[0018] The micro-energy collection device includes bow-shaped single crystal piezoelectric cantilever beam 5 , permanent magnet mass block 6 , rectangular single crystal piezoelectric cantilever beam 7 , spring 8 , permanent magnet 9 and coil 10 . There are 10 piezoelectric cantilever beams and 2 coils in the micro energy harvesting device. Among them, two rectangular single crystal piezoelectric cantilever beams 7 are located directly below the mouse button and are connected to the fixed plate 3, under which a permanent magnet 9 is connected through a ...

Abstract

The invention aims to provide a self-powered wireless mouse with micro-energy collecting devices. The self-powered wireless mouse comprises a mouse shell, a left key and a right key, a middle fixing plate is arranged at the bottom of the mouse shell, a rectangular single-crystal piezoelectric cantilever beam is arranged below the left key, one end of the rectangular single-crystal piezoelectric cantilever beam is connected with the middle fixing plate, and the lower side of the other end of the rectangular single-crystal piezoelectric cantilever beam is connected with a permanent magnet block by a spring. A cylindrical hole is formed in the portion, below the permanent magnet block, of the mouse shell, a coil is wound outside the cylindrical hole, a bow-shaped single-crystal piezoelectric cantilever beam is arranged below the rectangular single-crystal piezoelectric cantilever beam, one end of the bow-shaped single-crystal piezoelectric cantilever beam is connected with the middle fixing plate, and the other end of the bow-shaped single-crystal piezoelectric cantilever beam is connected with a permanent magnet mass block. The plurality of sets of micro-energy collecting devices are arranged, and the capturing efficiency of the mechanical energy of the human body can be improved to the maximum extent. And the piezoelectric cantilever beams of the piezoelectric type micro-energy collecting devices are structurally modified, so that the vibration frequency of the cantilever beams is increased, and the power generation power is effectively improved.

Description

technical field [0001] The invention relates to a mouse, specifically a wireless mouse. Background technique [0002] The disposable dry batteries used in most wireless mice have problems such as limited battery capacity, short service life, and inability to recycle, and they are more polluting to the environment. Although the rechargeable battery can alleviate the pollution problem of the battery to a certain extent, its price is relatively high, and it still needs to be charged frequently, which cannot fundamentally solve the problem that the wireless mouse uses a battery for power supply. [0003] The mouse generates a variety of unused micro-energy during use, including the pressure generated when the user presses the mouse and the mechanical motion force generated when the mouse is shaken. The patent "A self-driven mouse that can be used to collect body movement energy" (CN111984135A) installs piezoelectric energy harvesting devices on buttons, mouse pads, and inside t...
