Technical Field
[0001] This invention belongs to the field of photovoltaic technology and relates to a solar photovoltaic mouse pad and mouse with wireless charging function. Background Technology
[0002] Mouse pads are commonly used auxiliary mats when operating a mouse. Mouse pads come in various styles and have increasingly more functions. For example, Chinese Patent Publication No. CN210488520U, "A Multifunctional Mouse Pad," discloses a technical solution that uses a solar cell to charge a rechargeable battery, which then heats the heating layer of the mouse pad, thus preventing hands from getting cold when using the mouse in winter. However, this wastes electricity when the mouse pad heating is not needed in summer. In recent years, due to the widespread use of wireless mice, the battery life inside the mouse has become a point of criticism. How to charge wireless mice during use has become a desire for many. Summary of the Invention
[0003] The purpose of this invention is to develop a mouse pad with wireless charging functionality, which can charge a mouse using wireless charging technology and can also charge other electronic products that have a wireless charging protocol.
[0004] To achieve the above objectives, this invention uses a photovoltaic mouse pad with wireless charging function made of photovoltaic cells. The photovoltaic mouse pad stores energy by generating electricity through photovoltaic cells. At the same time, a coil is installed under the photovoltaic cells, and a magnet is placed inside the mouse. When using the mouse, moving the mouse cuts the magnetic lines of force to generate electrical energy. The photovoltaic cells and the coil together generate electrical energy to charge the rechargeable battery inside the mouse.
[0005] The specific technical solution adopted in this invention is: a solar photovoltaic mouse pad and mouse with wireless charging function, characterized in that: the mouse pad is provided with a photovoltaic cell on the mouse pad, a rechargeable battery inside the mouse pad, a power generation coil and a transmitting coil; the mouse is provided with a photovoltaic cell on the mouse, a rechargeable battery inside the mouse, a magnet and a receiving coil; the photovoltaic cell on the mouse pad charges the rechargeable battery inside the mouse pad, and the photovoltaic cell on the mouse charges the rechargeable battery inside the mouse; when the mouse is moved, the magnet inside the mouse moves and cuts the magnetic lines of force of the power generation coil inside the mouse pad to generate electrical energy to charge the rechargeable battery inside the mouse pad; the receiving coil wirelessly inductively transmits the signal from the rechargeable battery inside the mouse pad to the rechargeable battery inside the mouse; an infrared sensor is also provided on the edge of the mouse pad; when the mouse is moved, the infrared sensor is triggered to generate a signal to the controller to cut off wireless charging; when the mouse is charging and not moving, the infrared sensor does not detect a signal, and the controller turns on wireless charging.
[0006] The mouse pad is round or rectangular, and is composed of a transparent film layer, an adhesive film, a photovoltaic cell on the mouse pad, an adhesive film, and a soft rubber base shell. The power generation coil, the transmission coil, the rechargeable battery inside the mouse pad, and the infrared sensor are placed inside the soft rubber base shell.
[0007] The back of the photovoltaic cell on the mouse pad is printed with circuits and has chips, electronic components and connectors attached to it to form a photovoltaic circuit board. The photovoltaic circuit board connects the photovoltaic cell, power generation coil, transmission coil and infrared sensor on the mouse pad.
[0008] The number of power generation coils, transmitting coils, and infrared sensors can be set as needed. The optimal configuration is four power generation coils, one transmitting coil, and four infrared sensors. The power generation coils are placed in the middle of the four sides of the mouse pad, the infrared sensors are placed in the four corners of the mouse pad, and the transmitting coils are placed in the middle.
[0009] The soft rubber base is made of silicone rubber and is rectangular or circular. Four first grooves for placing the power generation coil are opened at the middle of the four sides of the rectangle or at the 90-degree dividing line of the circle. Four second grooves for placing infrared sensors are opened at the corners of the four sides. A third groove for accommodating the photovoltaic circuit board is opened in the middle. A fourth groove for placing the transmitting coil is opened below the third groove. A fifth groove for placing the rechargeable battery inside the mouse pad is opened on one side.
[0010] The power generation coil is formed by winding multiple coils on the hub of a cross-shaped wheel.
[0011] The transparent film layer is made of glass or a transparent and wear-resistant polymer material, such as polyethylene terephthalate (PET), thermoplastic polyurethane (TPU), polyvinyl chloride (PVC), polycarbonate (PC), etc.
[0012] The mouse includes an upper shell, a middle support frame, and a lower shell. The upper shell has a transparent window to house the photovoltaic cell on the mouse. The middle support frame houses the control circuit board, and the mouse contains an internal rechargeable battery, a receiving coil, and a magnet.
[0013] The photovoltaic cells on the mouse pad are thin-film batteries with glass or flexible substrates, such as perovskite cells and amorphous silicon cells.
[0014] The surface of the photovoltaic cell on the mouse pad is silkscreened with the positions for placing the infrared sensor and the wireless charging.
[0015] To prevent the mousepad edges from rubbing against your wrists, you can add decorative beveled edges around the mousepad. These edges can be rectangular, circular, or doll-shaped.
[0016] The photovoltaic circuit board of the photovoltaic mouse pad includes an energy harvesting circuit module, a magnetic cutting rectifier circuit module, and a wireless transmission circuit module; the control circuit board of the photovoltaic mouse includes an energy harvesting circuit module and a wireless receiving circuit module; wherein, the rechargeable battery inside the photovoltaic mouse pad is charged by the wireless transmission circuit module and the wireless receiving circuit module of the photovoltaic mouse connected through a wireless handshake protocol.
[0017] The energy harvesting circuit modules of the mouse pad and mouse both include a photovoltaic charging and discharging module and a DC-DC battery management module. The photovoltaic charging and discharging module includes an MPPT control module, a charging output module, and a voltage regulation output module, which are known technologies and will not be described in detail here.
[0018] The magnetic cutting rectifier circuit module of the mouse pad consists of four generator coils of the mouse pad generating AC power, which are rectified into DC power by their respective rectifier circuits and then connected in parallel. The DC power is then connected to the energy harvesting circuit module through a filter capacitor.
[0019] The wireless transmission circuit module of the mouse pad includes a microcontroller unit (MCU) and its peripheral circuit modules. When the four infrared sensors change from a state with a trigger signal to a state without a trigger signal and remain in a state without a trigger signal, and the voltage of the rechargeable battery in the mouse pad is greater than or equal to 3.3V, the MCU first starts the boost circuit, then starts the wireless transmission circuit, and searches for a wireless receiving load for charging.
[0020] The wireless transmission circuit module, when the rechargeable battery inside the mouse pad is in wireless output mode, triggers any one of the infrared sensors, or when the voltage of the rechargeable battery inside the mouse pad is lower than 3.1V (i.e., the preset low-voltage protection threshold), or when the rechargeable battery inside the mouse pad is fully charged for a set time, or when the search for wireless receiving load is greater than a set value, or when a metal foreign object is detected entering the wireless transmission range of the mouse pad and is not removed for a set time, the MCU shuts down the boost circuit and the wireless transmission circuit and enters a sleep state.
[0021] The wireless transmitting circuit module includes LEDs with the following states: When the wireless transmitting circuit is activated, the LED flashes red twice per second; when the wireless transmitting circuit's sensing area detects a load, the LED flashes blue twice per second; when the wireless transmitting circuit is outputting normally, the LED gradually changes brightness from 0% to 100% and back to 0% every 2 seconds; when the wireless receiving load is fully charged, the LED remains constantly blue; when the wireless transmitting circuit's battery voltage is below 3.3V, the LED alternates between blue and red twice per second; when the wireless transmitting circuit's battery voltage is below 3.1V, the LED alternates between blue and red five times per second for 10 seconds before entering sleep mode; when the wireless transmitting circuit detects a metallic foreign object, the LED flashes red five times per second.
[0022] The wireless receiving circuit module of the mouse searches for the wireless transmitting circuit module of the mouse pad to send a signal. After establishing a handshake protocol connection, it outputs 5V of electrical energy, which enters the energy harvesting module circuit through the anti-reverse charging diode and the filter capacitor. The energy harvesting module circuit then outputs power to the rechargeable battery inside the mouse.
[0023] The MCU's workflow is as follows: When the infrared sensor triggers charging, it reads whether the voltage of the rechargeable battery in the mouse pad is less than or equal to 3.1V. If "yes," it enters sleep mode; if "no," it checks if all four infrared sensors have no trigger signal. If "no," it enters sleep mode again; if "yes," it activates the wireless transmission circuit module, reads the wireless transmission module information, and checks if the wireless receiver is present and free of foreign objects. If "no," it shuts down the wireless transmission; if "yes," it continues to check if the rechargeable battery in the mouse is fully charged. If "yes," it shuts down the wireless transmission; if "no," it continues to check if all four infrared sensors have no trigger signal. If "no," it shuts down the wireless transmission module; if "yes," it checks whether continued charging is allowed. If "yes," it returns to reading the wireless transmission module information; if "no," it accumulates time to check if 60 seconds have been reached. If "yes," it shuts down the wireless transmission module; if "no," it returns to asking whether continued charging is allowed. If "yes," it shuts down the wireless transmission module. Shutting down the wireless transmission module means entering sleep mode, waiting for the infrared sensor to trigger again.
[0024] The positive effects of this invention are: by using photovoltaic cells and coils to generate electricity, the charging function of the mouse pad is increased, realizing wireless charging between the mouse pad and the mouse or other electronic products. Electricity is generated during the use of the mouse without extra effort, thus reducing battery pollution and saving energy. Attached Figure Description

[0038] like Figure 1 , Figure 2As shown, the mouse pad is rectangular, with a beveled edge sleeve 18 around its edge. A transparent film layer 1 is attached or laminated to the photovoltaic cell 2 on the mouse pad via adhesive film. The photovoltaic cell 2 on the mouse pad is attached to the soft rubber base shell 7 via adhesive film. Four first grooves 701 for placing four power generation coils 3 are opened in the middle of the four sides of the soft rubber base shell 7. Four second grooves 702 for placing four infrared sensors 5 are opened at the four corners. Two fifth grooves 705 for placing the rechargeable battery 6 inside the mouse pad are opened on one side. A third groove 703 is recessed in the middle of the soft rubber base shell 7 to accommodate the electronic components 203, chip 201 and connector 202 of the back patch of the photovoltaic cell 2 on the mouse pad. A fourth groove 704 for placing the transmitting coil 4 is further recessed in the third groove 703.
[0039] like Figure 3 As shown, the generator coil 4 is wheel-shaped, with multiple coils wound on the hub and cross-shaped reinforcing ribs inside the wheel.
[0040] like Figure 4 As shown, a photovoltaic circuit is provided on the back of the photovoltaic cell 2 on the mouse pad. Electronic components, connector 202 and chip 201 form an energy harvesting circuit module on the photovoltaic circuit.
[0041] like Figure 5 , Figure 6 As shown, the mouse includes an upper shell 8, a middle support 10, and a lower shell 17. A transparent window 801 is opened on the top of the upper shell 8. The photovoltaic cell 9 of the mouse is placed in the corresponding position inside the transparent window 801. The scroll wheel 11 and the control box 12 are installed on the middle support 10. The rechargeable battery 9, the light-sensing lens 4, the magnet 15, and the receiving coil 16 inside the mouse are installed on the lower shell 17.
[0042] like Figure 7 The diagram shows the energy harvesting circuit schematic for the mouse pad. U1 is either an SPV1050 or BQ25505. The PV+ positive input of the photovoltaic cell 2 on the mouse pad is connected to C3, R1, and the IN-HV pin of U1. R1 is connected to the MPP pin of U1, and then connected in series with resistors R4 and R7 to the PV- negative input and GND, forming the MPP maximum power point tracking detection. The PV+ positive input is connected in series with resistors R1 and R4 to the MPP-SET pin of U1, where R7 is connected in series to divide the voltage and connect to the PV- negative and GND, forming the MPP-SET maximum power reference voltage point. The STORE pin of U1 is connected to capacitor C2, series resistor R2, and the UVP pin of U1. Resistors R6 and R8 are connected to GND, forming the battery undervoltage circuit. The STORE pin of U1 is connected to capacitor C2, series resistors R2 and R6, and resistor R8, where the voltage is divided and connected to GND. The battery voltage divider is the EOC pin of U1, forming the battery output charging voltage setting circuit.
[0043] like Figure 8 The schematic diagram of the magnetic cutting rectifier circuit of the mouse pad shown shows that when the magnet 15 on the mouse triggers the four generating coils 3 of the mouse pad, the AC charge generated by each coil is connected to the respective rectifier circuits D4, D5, D6, D7, D8, D9, D10, D11, D12, D13, D14, D15, D16, D17, D18, D19 through the J8, J9, J10, J11 interfaces, converting the AC power into DC power. After being connected in parallel, the DC power enters the energy harvesting chip U1 through the C5 filter capacitor.
[0044] like Figure 9 The schematic diagram of the wireless transmission circuit of the mouse pad shows that when all four infrared sensors 5 connected to J2, J3, J4, and J5 are in a no-trigger signal state, and the voltage of the rechargeable battery 6 (J6 and J7 interfaces) inside the mouse pad is greater than or equal to 3.3V, the U4MCU first starts the boost circuit (including the circuit composed of C36, C37, C38, C40, C41, R35, R37, R38, U3, L3, and D20), and then starts the wireless transmission circuit (including C6, C7, C8, C9, C10, C11, C12, and C...). The circuit consisting of C13, C14, C15, C16, C17, C18, C19, C20, C21, C22, C35, C39, C42, D3, L2, LED1, Q1, Q2, Q3, R9, R10, R11, R12, R13, R14, R15, R16, R17, R18, R19, R20, R21, R22, R24, R25, R26, R27, R28, R30, R31, R36, R39, R40, R41, U2, and U4.
[0045] When the wireless transmitting circuit searches for a wireless receiving device, LED1 flashes red (twice per second). When a handshake protocol feedback is received from a wireless receiving device, LED1 flashes blue (twice per second). The U4 MCU comparator circuit detects this and outputs the pre-set rated power wirelessly. LED1 displays a blue gradient (0% brightness → 100% brightness → 0% brightness → off, cycling for 2 seconds). When the wireless receiving device is fully charged, LED1 remains solid blue, indicating full charge. To recharge the mouse's internal battery 13, the infrared sensor 5 must be retried from a trigger signal state to a non-trigger signal state and remain in a non-trigger signal state. Furthermore, the voltage of the internal battery 6 must be greater than or equal to 3.3V before U4 can be retried. The MCU starts the boost circuit and wireless transmission circuit. When the rechargeable battery 6 inside the mouse pad is in wireless output mode, if a metal foreign object (minimum diameter 10mm or more) enters between the wireless transmission and wireless receiving modules, wireless transmission will be paused, and LED1 will flash red 5 times per second. After the metal foreign object is removed, the wireless transmission circuit will re-scan the handshake protocol, and the red light will flash red twice per second. If the metal foreign object is not removed, the circuit will enter sleep mode after 60 seconds (i.e., the boost circuit and wireless transmission circuit will be turned off). When the rechargeable battery 13 inside the mouse is recharged, the infrared sensor 5 needs to be retried from a state with a trigger signal to a state without a trigger signal and remain in a state without a trigger signal. Only when the voltage of the rechargeable battery 6 inside the mouse pad is greater than or equal to 3.3V can the U4 MCU start the boost circuit and wireless transmission circuit be retried.
[0046] When the rechargeable battery 6 inside the mouse pad is in wireless output mode, any one of the infrared sensors 5 will trigger a signal to immediately stop the wireless output and enter sleep mode, and LED 1 will not display (the boost circuit and the wireless transmission circuit will be turned off).
[0047] When the rechargeable battery 6 inside the mouse pad is in wireless output mode, if the voltage of the rechargeable battery 6 inside the mouse pad is lower than 3.3V (preset low battery alarm threshold), the blue light will flash red twice per second. If the battery voltage is lower than 3.1V (preset low battery protection threshold), the blue light will flash red five times per second for 10 seconds and then enter sleep mode. When recharging the rechargeable battery 13 inside the mouse pad, the infrared sensor 5 needs to be retried from a state with a trigger signal to a state without a trigger signal and remain in a state without a trigger signal. Only when the voltage of the rechargeable battery 6 inside the mouse pad is greater than or equal to 3.3V can the U4 MCU start-up boost circuit and wireless transmission circuit be retried.
[0048] like Figure 10 The diagram shown is a schematic of the mouse's energy harvesting circuit. Figure 7 The principle is the same, but the photovoltaic cell 13 on the mouse replaces the photovoltaic cell 2 on the mouse pad.
[0049] like Figure 11 The diagram shows the wireless receiving circuit schematic of the mouse. The internal wireless receiving module of the mouse (including the circuit composed of C13, C27, C28, C29, C30, C31, C32, C33, C34, C43, C44, C45, C46, C47, C48, C49, C50, C51, C52, D23, D24, L5, R44, R45, R46, R47, R48, R49, and U6) wirelessly receives energy from the mouse pad after a handshake protocol through the wireless transmitting circuit TX of the mouse pad. The energy is output at 5V through pin 4 of IC U6 of the wireless receiving module, and then passes through diode D23 (to prevent backflow of charge from the photovoltaic cells into the wireless receiving module and cause losses) and filter capacitor C13 into the energy harvesting module circuit. The energy harvesting module circuit outputs power to the battery connected to connector J12.
[0050] like Figure 12 The flowchart of the MCU operation of the mouse pad shown illustrates the following process: When infrared sensor 5 triggers charging, it checks if the voltage of the rechargeable battery 6 inside the mouse pad is less than or equal to 3.1V. If "yes," it enters sleep mode; if "no," it checks if all four infrared sensors 5 have no trigger signal. If "no," it enters sleep mode again; if "yes," it activates the wireless transmission circuit module, reads the wireless transmission module information, and checks if the wireless receiver is present and if there are any foreign objects. If "no," it shuts down the wireless transmission; if "yes," it continues to check if the rechargeable battery 13 inside the mouse is fully charged. If "yes," it shuts down the wireless transmission; if "no," it continues to check if all four infrared sensors 5 have no trigger signal. If "no," it shuts down the wireless transmission module; if "yes," it checks whether continued charging is allowed. If "yes," it returns to reading the wireless transmission module information; if "no," it accumulates time to check if 60 seconds have been reached. If "yes," it shuts down the wireless transmission module; if "no," it returns to asking whether continued charging is allowed. If "yes," it shuts down the wireless transmission module. Shutting down the wireless transmission module means entering sleep mode, waiting for the infrared sensors to trigger again.
[0051] The following examples illustrate the beneficial effects: The mouse pad measures 300*200mm and uses a low-light amorphous silicon battery with a power conversion efficiency of 5%. Under standard light intensity and 6 hours of sunlight per day, it generates 85mAh per hour, totaling 510mAh per day. Magnetic cutting for 6 hours generates an average of 10mAh per hour, totaling 60mAh per day. By wirelessly charging the mouse (with an average conversion efficiency of 80%), 448mAh of power can be transferred to the mouse for additional charge.
[0052] Using perovskite photovoltaic cells, the power generation conversion efficiency reaches over 10%. With 6 hours of sunshine per day, it generates 170mAh per hour, totaling 1020mAh per day. With 6 hours of magnetic cutting, it generates an average of 10mAh per hour, totaling 60mAh per day. By wirelessly transmitting power to the mouse (with an average conversion efficiency of 80%), 864mAh can be transferred to the mouse to replenish its power.
[0053] Generally, the rechargeable battery in a typical wireless mouse is 240mAh. Using the mouse for 1 hour will consume 0.4mAh, so using the mouse for 6 hours will consume 2.4mAh, which is more than enough to charge the battery inside the mouse.
[0054] The remaining battery power can be used to charge mobile phones and other devices.

If "no," it enters sleep mode again; if "yes," it starts the wireless transmission circuit module, reads the wireless transmission module information, and checks whether the wireless receiver is present and free of foreign objects. If "no," it shuts down the wireless transmission; if "yes," it continues to check whether the rechargeable battery in the mouse is fully charged. If "yes," it shuts down the wireless transmission; if "no," it continues to check whether all four infrared sensors have no trigger signal. If "no," it shuts down the wireless transmission module; if "yes," it checks whether continued charging is allowed. If "yes," it returns to reading the wireless transmission module information; if "no," it accumulates time to check if 60 seconds have been reached. If "yes," it shuts down the wireless transmission module; if "no," it returns to asking whether continued charging is allowed. If "yes," it shuts down the wireless transmission module. Shutting down the wireless transmission module means entering sleep mode, waiting for the infrared sensor to trigger again.
