[0002] In recent years, with the development of my country's economy, computers have become more and more popular than ever before, and the mouse, as an input device for computers, has also ushered in an unprecedentedly broad market.
[0003] A mouse is an external input device for computers, and also an indicator for positioning on the computer's display system using horizontal and vertical coordinates. It gets its name from its resemblance to a mouse. The purpose of using a mouse is to make computer operation simpler and faster, replacing the cumbersome commands of the keyboard.
[0004] Currently, mice on the market are mainly divided into two types: wireless mice and wired mice. Wired mice use a USB connection to power the computer, while wireless mice are powered by batteries. Due to their convenience, wireless mice are gaining an increasingly larger market share. However, they also face challenges. On the one hand, the use of disposable batteries generates waste batteries, which is detrimental to environmental protection, and replacing batteries regularly is costly. On the other hand, rechargeable batteries cause downtime for the mouse during charging, which is inconvenient for users.

[0022] The present invention achieves the following technical advantages over the prior art: The wireless mouse of the present invention includes a shell, a scroll wheel power generation unit, left and right button power generation units, and a swing power generation unit. The shell houses a circuit board with a rectifier and a battery, the rectifier being connected to the battery. The scroll wheel power generation unit includes a scroll wheel rotatably connected to the shell. The scroll wheel contains an annular electrode layer, an annular friction layer, and a first friction ball. The annular electrode layer is connected to the inner wall of the scroll wheel. There are two annular electrode layers with a gap between them. The annular electrode layer is connected to the rectifier and is located between the inner wall of the scroll wheel and the annular friction layer. The first friction ball is located within the friction track formed by the annular friction layer and can generate power through friction. The roller reciprocates within the track; both ends of the roller are connected to end power generation components, each including an end friction plate disposed on the outer wall of the roller. The housing is provided with a shell friction plate and a shell electrode plate, with the shell friction plate located between the end friction plate and the shell electrode plate. There are two shell electrode plates with a gap between them, and the shell electrode plates are connected to a rectifier element.

[0023] The wireless mouse of the present invention simultaneously comprises a scroll wheel power generation unit, left and right button power generation units, and a oscillation power generation unit. The scroll wheel power generation unit contains an annular electrode layer, an annular friction layer, and a first friction ball. During use of the wireless mouse, rotating the scroll wheel causes the first friction ball to roll back and forth within the friction track formed by the annular friction layer. The first friction ball makes frictional contact with the annular friction layer, generating an equal amount of charge. As the first friction ball rolls from one side of the annular electrode layer to the other, the charge flows from one side of the annular electrode layer to the other, forming a current. Due to gravity, the first friction ball can only move along the axis of rotation of the scroll wheel. The scroll wheel reciprocates downwards. When the first friction ball rolls back in the opposite direction, the charge flows in the opposite direction, forming a reverse current. This current is rectified by a rectifier and then fed into the battery. Similarly, the end-mounted power generation components connected to both ends of the scroll wheel generate charge when the scroll wheel rotates, as the end friction plates rub against the shell friction plates. This charge flows between the two shell electrode plates, forming a current, which is rectified by a rectifier and then fed into the battery. The left and right button power generation units and the oscillation power generation unit also generate current, which is fed into the battery to power the wireless mouse, ensuring continuous use and avoiding environmental pollution caused by battery replacement, thus improving the user experience. It should also be noted that the scroll wheel power generation unit, the left and right button power generation units, and the oscillation power generation unit are connected in parallel, which improves the reliability of the wireless mouse.

Detailed Implementation
[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0038] The purpose of this invention is to provide a wireless mouse that solves the problems existing in the prior art, enables continuous use of the wireless mouse without causing environmental pollution, and improves the ease of use of the wireless mouse.
[0039] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0040] This invention provides a wireless mouse, comprising a housing 100, a scroll wheel power generation unit 200, left and right button power generation units 300, and a swing power generation unit 400. The housing 100 houses a circuit board 1, on which a rectifier element 2 and a battery 3 are mounted. The rectifier element 2 is connected to the battery 3. The scroll wheel power generation unit 200 includes a scroll wheel 4, rotatably connected to the housing 100. The scroll wheel 4 contains an annular electrode layer 5, an annular friction layer 6, and a first friction ball 7. The annular electrode layer 5 is connected to the inner wall of the scroll wheel 4. There are two annular electrode layers 5 with a gap between them. The annular electrode layer 5 is connected to the rectifier element 2 and is located between the inner wall of the scroll wheel 4 and the annular friction layer 6. The first friction ball 7 is located within the friction track formed by the annular friction layer 6 and can reciprocate within the friction track. Both ends of roller 4 are connected to end power generation components. The end power generation components include end friction plates 9, which are disposed on the outer wall of roller 4. The housing 100 is provided with housing friction plates 10 and housing electrode plates 8. The housing friction plates 10 are located between the end friction plates 9 and the housing electrode plates 8. There are two housing electrode plates 8 with a gap between them. The housing electrode plates 8 are connected to the rectifier element 2. The end friction plates 9 and housing friction plates 10 are opposite to each other and can contact each other. The housing friction plates 10 and the end friction plates 9 correspond one-to-one. The left and right key power generation unit 300 can generate electrical energy and is connected to the battery 3. The swing power generation unit 400 can also generate electrical energy and is connected to the battery 3. The roller power generation unit 200, the left and right key power generation unit 300 and the swing power generation unit 400 are arranged in parallel.
[0041] The wireless mouse of the present invention is equipped with a scroll wheel power generation unit 200, left and right button power generation units 300, and a oscillation power generation unit 400. The scroll wheel 4 of the scroll wheel power generation unit 200 contains an annular electrode layer 5, an annular friction layer 6, and a first friction ball 7. During use of the wireless mouse, rotating the scroll wheel 4 causes the first friction ball 7 to roll back and forth within the friction track formed by the annular friction layer 6. The first friction ball 7 comes into frictional contact with the annular friction layer 6 and generates an equal amount of charge. For details, please refer to [reference needed]. Figure 8 As the first friction ball 7 rolls from the left annular electrode layer 5 to the right annular electrode layer 5, positive charges flow from the left annular electrode layer 5 to the right annular electrode layer 5, forming a current. Due to gravity, the first friction ball 7 can only reciprocate below the rotation axis of the roller 4. When the first friction ball 7 rolls back in the opposite direction, positive charges flow in the opposite direction, forming a reverse current. The current is rectified by the rectifier element 2 and then flows into the battery 3. Similarly, the end power generation components connected to the axial ends of the roller 4 generate an equal amount of charge when the roller 4 rotates, with the end friction plate 9 rubbing against the shell friction plate 10. Please refer to [reference needed]. Figure 9As the end friction plate 9 moves from the left shell electrode plate 8 to the right shell electrode plate 8, positive charges flow from the left shell electrode plate 8 to the right shell electrode plate 8, forming a current. Subsequently, the end friction plate 9 rotates from the right shell electrode plate 8 to the left shell electrode plate 8, driving positive charges to flow back from the right shell electrode plate 8 to the left shell electrode plate 8, forming a reverse current. This current is rectified by the rectifier element 2 and then fed into the battery 3. The left and right button power generation units 300 and the swing power generation unit 400 can also generate current, which is fed into the battery 3 to power the wireless mouse, ensuring continuous use of the wireless mouse and avoiding environmental pollution caused by battery replacement, thus improving the user experience. It should also be noted that the parallel arrangement of the scroll wheel power generation unit 200, the left and right button power generation unit 300, and the swing power generation unit 400 improves the working reliability of the wireless mouse.
[0042] Specifically, the left and right button power generation unit 300 is disposed within the housing 100, including a bracket 11, a rolling groove 12, a groove electrode plate 13, a groove friction plate 14, a second friction ball 15, and a rolling cover 16. The bracket 11 is fixed to the circuit board 1, and the rolling cover 16 is located on top of the rolling groove 12 and the two are connected. The rolling cover 16 is positioned directly opposite the left and right button positions of the housing 100. The groove electrode plate 13, the groove friction plate 14, and the second friction ball 15 are all located within the area enclosed by the rolling groove 12 and the rolling cover 16. Within the space, the middle of the rolling groove 12 is rotatably connected to the support 11. The groove electrode plate 13 and the groove friction plate 14 are both disposed within the rolling groove 12. The groove electrode plate 13 is located between the rolling groove 12 and the groove friction plate 14. The second friction ball 15 is rolled within the space enclosed by the rolling groove 12 and the rolling cover 16 and is always in contact with the groove friction plate 14. There are two groove electrode plates 13, with a gap between them. The groove electrode plates 13 are connected to the rectifier element 2. The middle of the rolling groove 12 is hinged to the support 11, causing the left and right button power generation units 300 to form a lever structure. When using the wireless mouse, taking a single left click as an example, pressing the left button on the housing 100 causes one end of the rolling cover 16 to press downwards. The second friction ball 15 rolls within the space enclosed by the rolling groove 12 and the rolling cover 16, and the second friction ball 15 rubs against the groove friction plate 14, generating an electric charge. Figure 10As shown, during the process of the second friction ball 15 rolling from the left groove electrode plate 13 to the right groove electrode plate 13, positive charge flows from the left groove electrode plate 13 to the right groove electrode plate 13, forming a current. When the left button of the wireless mouse is reset, the end of the scroll cover 16 that was pressed down moves upward, and the second friction ball 15 returns to its initial position along the scroll groove 12. The second friction ball 15 rolls from the right groove electrode plate 13 to the left groove electrode plate 13, driving positive charge to flow from the right groove electrode plate 13 back to the left groove electrode plate 13, thereby forming a reverse current. It should be explained here that the shell 100 of the wireless mouse includes a left button and a right button, and left and right button power generation units 300 are set at corresponding positions of the left and right buttons.
[0043] To ensure smooth reset of the rolling groove 12 and rolling cover 16, a magnet assembly 17 is provided at one end of the rolling groove 12. The magnet assembly 17 includes two magnets with the same magnetic poles. One magnet is connected to the rolling groove 12 and located on the side of the rolling groove 12 facing the circuit board 1, while the other magnet is located on the circuit board 1. The two magnets are positioned opposite each other. When the left and right buttons of the housing 100 are pressed down, one end of the rolling cover 16 is pressed down, causing the rolling groove 12 to move downwards, approaching the magnet on the circuit board 1. Since like poles repel each other, this pushes the rolling groove 12 and rolling cover 16 upwards, resetting the left and right buttons after they are pressed, and simultaneously generating electricity.
[0044] In this specific embodiment, the rolling groove 12 is connected to the rolling cover 16 by fastening screws 18, which makes the connection tight and easy to disassemble and assemble.
[0045] More specifically, the oscillating power generation unit 400 is disposed within the housing 100. The oscillating power generation unit 400 includes an oscillating body 19, an oscillating friction assembly 20, and an oscillating cover 21. The oscillating cover 21 is disposed on top of the oscillating body 19 and the two are connected. The oscillating friction assembly 20 is located within the space enclosed by the oscillating body 19 and the oscillating cover 21. The oscillating friction assembly 20 includes an oscillating electrode plate 22, an oscillating friction plate 23, and a third friction ball 24. The oscillating body 19 has an oscillating groove 25. The oscillating electrode plate 22 and the oscillating friction plate 23 are both disposed within the oscillating groove 25. The oscillating electrode plate 22 is located between the oscillating groove 25 and the oscillating friction plate 23. The third friction ball 24 is rolled within the space enclosed by the oscillating body 19 and the oscillating cover 21 and always maintains contact with the oscillating friction plate 23. There are two oscillating electrode plates 22, and there is a gap between the two oscillating electrode plates 22. The oscillating electrode plates 22 are connected to the rectifier element 2. The swing power generation unit 400 is located in the rear space inside the housing 100, similar to the left and right button power generation unit 300, and is still referred to Figure 10When the wireless mouse moves, the third friction ball 24 rolls in the swing groove 25 and comes into frictional contact with the swing friction plate 23. The third friction ball 24 generates an equal amount of charge. As the third friction ball 24 rolls from the left swing electrode plate 22 to the right swing electrode plate 22, positive charge flows from the left swing electrode plate 22 to the right swing electrode plate 22, forming a current. Subsequently, the third friction ball 24 rolls from the right swing electrode plate 22 to the left swing electrode plate 22, driving positive charge to flow from the right swing electrode plate 22 back to the left swing electrode plate 22, thereby forming a reverse current.
[0046] Because the sliding motion of a wireless mouse is uneven, the current generated fluctuates and its direction is easily changed. Therefore, a rectifier element 2 is set up to rectify the current generated by friction and then feed it into the battery 3.
[0047] In this specific embodiment, there are multiple sets of swing friction components 20, and the swing groove 25 corresponds one-to-one with the swing friction components 20. Setting multiple sets of swing friction components 20 can enhance the power generation capacity of the swing power generation unit 400.
[0048] Accordingly, multiple sets of swing friction components 20 are arranged in parallel to improve the reliability of the swing power generation unit 400. In addition, multiple swing grooves 25 are arranged in parallel. In other specific embodiments of the present invention, the setting direction of the swing grooves 25 can be adjusted according to actual needs, so that the swing power generation unit 400 can collect electrical energy when the wireless mouse slides in all directions.
[0049] For easy disassembly and maintenance, the swing body 19 and the swing cover 21 are detachably connected, and bolt connection, snap-fit or other connection methods can be selected.
[0050] Furthermore, the wireless mouse also includes a moisture-proof unit, which is located inside the housing 100. The moisture-proof unit includes a cooling fan 26 and a heating element 27. Both the cooling fan 26 and the heating element 27 are located on the circuit board 1 and are connected to the battery 3. The housing 100 is provided with heat dissipation holes 28, and the cooling fan 26 is positioned directly opposite the heat dissipation holes 28. The cooling fan 26 can promote air circulation, allowing the heat inside the housing 100 to be smoothly transferred to the external environment, thereby improving the heat dissipation capacity of the wireless mouse. At the same time, the heating element 27 is provided so that when the humidity inside the housing 100 is too high, the heating element 27 can be turned on to evaporate the moisture, preventing damage to components caused by excessive humidity and extending the service life of the wireless mouse.
[0051] In other specific embodiments of the present invention, the moisture-proof unit further includes a temperature sensor 29 and a humidity sensor 30. Both the temperature sensor 29 and the humidity sensor 30 are mounted on the circuit board 1. The temperature sensor 29 monitors the temperature inside the housing 100, thereby controlling the operating state of the cooling fan 26. The humidity sensor 30 monitors the humidity inside the housing 100, thereby controlling the operating state of the heating element 27. It should be explained that setting up a controller to collect the monitoring data from the temperature sensor 29 and the humidity sensor 30, and controlling the operating states of the cooling fan 26 and the heating element 27, as well as the setup of the controller and its connection to the various components via the circuit board 1, are all common practices among those skilled in the art and will not be elaborated upon here. Furthermore, to further improve the heat dissipation efficiency of the wireless mouse, multiple cooling fans 26 can be provided. In this specific embodiment, the cooling fans 26 are arranged at equal intervals to enhance heat dissipation uniformity. In addition, the wireless mouse also includes a wireless module 32 and a switch 31. The wireless module 32 is used to connect to other devices such as a computer, and the switch 31 is connected to the battery 3. The switch 31 can be turned off when not in use to save energy.
[0052] The wireless mouse of this invention includes a scroll wheel power generation unit 200, left and right button power generation units 300, and a oscillation power generation unit 400. All three power generation units are based on the triboelectric principle. Due to the different electron-gaining and loss capabilities of materials, triboelectric charging causes the surface of the active friction material to carry a charge, while the surface of the passive friction material carries an opposite charge with an equal charge density. Since the triboelectric charge is only distributed on the surface of the friction layer, and the friction layer has excellent insulation properties, charge leakage will not occur within a certain period. This invention uses FEP material as the active friction material (first friction ball 7, second friction ball 15, and third friction ball 24); polyamide is used as the passive friction material, completely covering the two symmetrical electrodes. When the FEP film slides onto the nylon film surface, negative charges will enter the FEP film surface from the nylon film surface. For the positive charge on the nylon surface, since it remains stationary, the potential induced between the two electrodes remains constant, and it cannot provide any driving force for the flow of charge on the external load. Therefore, all the driving force for the directional movement of the charge comes from the sliding of the negatively charged FEP film. When the FEP film aligns with the left electrode layer, the positive charges in the circuit are attracted to the upper surface of the left electrode. Then, as the FEP film slides to the right, the positive charges in the circuit flow from the left electrode to the right electrode through the load. When the FEP film aligns with the right electrode, all the positive charges flow into the right electrode. Subsequently, the FEP film moves from the right electrode to the left electrode, with the current direction being the same as the direction of the FEP film's movement. It is also important to emphasize that in practical applications, nanostructures or microstructures, such as nanoparticles, nanogrooves, and microgrooves, can be fabricated on the surfaces of materials that rub against each other to increase the contact area, thereby generating more triboelectric charges on the surface and enhancing the output electrical energy.
[0053] The wireless mouse of the present invention includes a scroll wheel power generation unit, a left and right button power generation unit, and a swing power generation unit. The three units are independent of each other and do not affect each other. Each unit can independently complete the power supply work, thereby improving the power supply efficiency.
[0054] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
