Problems solved by technology

However, the disadvantages of the wireless mouse are also very obvious. Now the wireless mice on the market are all equipped with replaceable or rechargeable dry batteries and lithium batteries to power the wireless mouse.
When the battery power is low, the wireless mouse cannot work normally and needs to be charged or replaced, which will bring trouble to the user virtually, and the dry battery after use will also pollute the environment, which is not in line with the concept of green and sustainable development
[0003] With the development of science and technology, computers have become an indispensable part of people's daily life. People sit in front of computers for longer and longer, and use the mouse for longer and longer. Long time will inevitably cause physical and mental fatigue and affect physical health.

Embodiment 1

[0039] see figure 1 , based on piezoelectric and triboelectric self-powered multi-functional wireless mouse, including mouse shell, mouse wheel, mouse left and right buttons and optical sensor at the bottom of the mouse, with three sets of independent self-generating devices, namely, wheel power generation device, left and right button single Striking power generation device and bottom friction power generation device; roller power generation device is set at the mouse wheel, left and right click power generation device is set under the left and right mouse buttons, friction power generation device is set around the optical sensor at the bottom of the mouse; the above three power generation methods work independently, Non-interfering with each other, the current generated by the three power generation methods is rectified and then connected to the battery to store the electric energy in the battery. The battery supplies power to the wireless mouse display to display relevant in...

Embodiment 2

[0042] This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0043] In this embodiment, the roller generating device is composed of a roller 2, a roller shaft 3, a flower wheel 4, a double crystal piezoelectric ceramic sheet 7, a fixed substrate 8 and related leads; 2 The connections are arranged on the left and right sides of the roller 2 inside the mouse shell, one end of the double crystal piezoelectric ceramic sheet 7 is in contact with the flower wheel 3, and the other end is fixed on the fixed substrate 8 inside the mouse, so that the double crystal piezoelectric ceramic sheet 7 forms a cantilever beam structure ; When the user is sliding the mouse wheel 2, the wheel 2 drives the flower wheel 4 at both ends to rotate through the wheel shaft 3, and the flower wheel 3 constantly stirs the contact end of the double crystal piezoelectric ceramic sheet 7 due to the rotation, thereby causing the piezoelectric ceramic cantilever When ...

Embodiment 3

[0050] Such as figure 1 , figure 2 As shown, in this embodiment, the roller power generation system is composed of a roller 2, a roller shaft 3, a flower wheel 4, a double crystal piezoelectric ceramic sheet 7 and a fixed substrate 8; the flower wheel 4 is connected to the wireless mouse wheel 2 through the roller shaft 3 Set on the left and right sides of the roller 2 inside the main body shell, one end of the double crystal piezoelectric ceramic sheet 7 is in contact with the flower wheel 3, and the other end is fixed on the fixed substrate 8 inside the mouse, so that the double crystal piezoelectric ceramic sheet 7 forms a cantilever beam structure. When the user slides the mouse wheel 2, the wheel 2 drives the flower wheel 4 at both ends to rotate through the wheel shaft 3, and the flower wheel 3 continuously moves the contact end of the double crystal piezoelectric ceramic sheet 7 due to the rotation, thereby forming a piezoelectric ceramic cantilever beam. Vibration oc...

Abstract

The invention discloses a piezoelectric and friction power generation-based self-powered multifunctional wireless mouse, which comprises a mouse shell, a mouse wheel, left and right mouse keys and a mouse bottom optical sensor, and is provided with three sets of independent self-power generation devices, namely a wheel power generation device, a left and right key single-click power generation device and a bottom friction power generation device. The wheel power generation device is arranged at a mouse wheel, the left and right key single-click power generation device is arranged below left and right keys of the mouse, and the friction power generation device is arranged around an optical sensor at the bottom of the mouse. The three power generation modes act independently and do not interfere with one another, and generated current is rectified and then electric energy is stored in the storage battery to supply power to other assemblies. A wireless module is further arranged to be communicated and interconnected with a mobile phone and a computer so as to achieve more functions. According to the wireless mouse, wireless intercommunication and interconnection can be carried out, real-time information and use history information can be displayed, and a user can carry out customized setting according to requirements; and the LCD display screen can display the use information, sothat a user can master the use condition.

Description

technical field [0001] The invention relates to the interdisciplinary subject of mechanics and electricity, belongs to the field of office supplies, in particular to the field of wireless mouse, and specifically relates to a self-powered multifunctional wireless mouse based on piezoelectricity and friction power generation. Background technique [0002] The mouse is one of the most frequently used devices in daily office work. It is an input device for computers. It is divided into two types: wired mouse and wireless mouse. Due to its convenience, the market share of wireless mouse is getting higher and higher. But the shortcoming that wireless mouse exists is also very obvious, and wireless mouse all is that internal setting can change or rechargeable dry battery and lithium battery supply power for wireless mouse now on the market. When the battery power is low, the wireless mouse cannot work normally and needs to be charged or replaced, which virtually brings trouble to t...
