Abstract
Description
Technical Field
[0001] This invention relates to the field of mobile power technology, and more specifically to a wireless charging mobile power supply. Background Technology
[0002] In the esports industry, professional wireless mice are high-performance peripherals designed to meet the demands of high-intensity, low-latency, and precise operation. Their core advantage lies in freeing players from the constraints of cables, providing them with greater control freedom. However, precisely because of this, these mice typically incorporate power-intensive components such as high refresh rate sensors, high-speed main control chips, and RGB lighting effects, resulting in significantly higher power consumption than ordinary mice. During hours of continuous training or competition, the mouse battery may not be able to support continuous use. If the connection is lost due to depleted battery at a crucial moment, it will directly affect the player's performance and even the outcome of the competition.
[0003] Currently, the mainstream charging methods for gaming wireless mice are battery replacement and wired charging. Both methods carry the risk of unpredictable power outages due to battery depletion or connection to a charging cable. Such sudden power interruptions can directly disrupt the continuity of gameplay, which is especially fatal in crucial moments of competitive play.
[0004] To address the aforementioned problems, this invention proposes a wireless charging mobile power supply. Summary of the Invention
[0005] (1) Technical problems to be solved
[0006] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a wireless charging mobile power supply to solve the above-mentioned technical problems.
[0007] (2) Technical solution
[0008] To achieve the objectives of this invention, the technical solution adopted is as follows:
[0009] A wireless charging power bank includes: a multi-layer structure, comprising, from bottom to top: a support layer for providing structural support; a wireless charging layer containing multiple closely arranged and arrayed transmitting coils; a surface layer forming a working surface for direct movement and operation of a wireless gaming mouse; a position detection module disposed between the support layer and the wireless charging layer for real-time detection of the movement position of the wireless gaming mouse on the surface layer; and a main control circuit board disposed on the support layer, which dynamically switches and activates one or more transmitting coils located directly below the wireless gaming mouse based on the real-time movement position detected by the position detection module, so as to achieve uninterrupted charging during the movement and operation of the wireless gaming mouse.
[0010] Furthermore, the position detection module is an energy recovery layer, which generates an induction signal through the principle of electromagnetic induction. The main control circuit board processes the induction signal to obtain the real-time coordinates of the wireless gaming mouse.
[0011] Furthermore, the energy recovery layer includes: a mounting substrate fixedly connected to the top of the support layer; a plurality of permanent magnets arranged in an array on the mounting substrate; and an energy recovery coil layer disposed on the permanent magnets through an isolation layer, including an FPC substrate and a plurality of recovery coils etched on the FPC substrate. The recovery coils are arranged in a one-to-one correspondence with the permanent magnets. When the wireless gaming mouse moves, the magnets or metal components inside it disturb the static magnetic field generated by the permanent magnets, causing the recovery coils to generate the induced signal.
[0012] Furthermore, the permanent magnets are arranged in a rectangular array, and adjacent permanent magnets are arranged in an alternating N / S pole configuration to form a uniform magnetic field gradient.
[0013] Furthermore, the main control circuit board adopts time-division multiplexing control, dividing the working cycle into charging time slots and detection time slots; during the charging time slot, the main control circuit board controls the wireless charging layer to perform wireless charging; during the detection time slot, the main control circuit board controls the position detection module to perform position detection; wherein, the energy recovery layer generates a sensing signal during the detection time slot.
[0014] Furthermore, it also includes an LED light source module, which is arranged around the edge of the multi-layer structure. The electrical energy generated by the disturbance of the static magnetic field in the energy recovery layer is collected and used to power the LED light source module to form a dazzling effect associated with the movement state of the wireless device.
[0015] Furthermore, it also includes a magnetic shielding layer disposed between the position detection module and the wireless charging layer. The magnetic shielding layer is made of ferrite or nanocrystalline soft magnetic material and is used to block the interference of the wireless charging magnetic field on the energy recovery detection signal.
[0016] Furthermore, the support layer is a metal plate with a silicone pad fixedly connected to its bottom and grooves distributed in a grid pattern. The silicone pad is attached to the area outside the grooves in the form of a dot matrix or stripes to achieve anti-slip and heat dissipation in a coordinated manner.
[0017] Furthermore, the wireless charging layer also includes a coil substrate located at the bottom of the transmitting coil for fixing the transmitting coil, and an insulating layer is provided on the top of the transmitting coil.
[0018] Furthermore, an isolation strip is fixedly connected to the support layer, which isolates the main control circuit board from the wireless charging layer and the position detection module.
[0019] (3) Beneficial effects:
[0020] A. In this invention, by setting a position detection module, the movement position of the wireless gaming mouse on the surface can be detected in real time. By setting a main control circuit board, one or more transmitting coils located directly below the wireless gaming mouse can be dynamically switched and activated based on the movement position detected in real time by the position detection module. This enables uninterrupted charging during the movement operation of the wireless gaming mouse. Compared with traditional battery replacement or wired charging, this wireless charging power bank can avoid the problem of power interruption breaking the continuity of game operation.
[0021] B. In this invention, by setting up an energy recovery layer, when the wireless gaming mouse moves, the static magnetic field generated by the magnet or metal component inside the mouse disturbing the permanent magnet causes the recovery coil to generate the aforementioned induction signal. This allows the main control circuit board to analyze the characteristics of the signal and track the position of the mouse on the surface in real time, providing a positioning basis for uninterrupted wireless charging and achieving precise power supply.
[0022] C. In this invention, by setting an energy recovery layer, when the wireless gaming mouse moves, the static magnetic field generated by the magnet or metal component inside the mouse disturbs the permanent magnet, causing a change in magnetic flux in the recovery coil, thereby inducing a weak induced current in each recovery coil. After the induced current is rectified, filtered, and boosted by the power harvesting circuit on the main control circuit board, it is used to drive the LED light strip, and finally presents a dazzling light effect on the frame that is synchronized with the mouse operation.

[0034] The following is in conjunction with the instruction manual appendix. Figure 1-9 The present invention is further illustrated by the embodiments:
[0035] like Figures 1-3 As shown, a wireless charging power bank is mainly used to solve the problem of the continuity of game operation affected by the power failure of a gaming wireless mouse. It adopts a multi-layer structure, which includes a support layer 1, a wireless charging layer 2 and a surface layer 3 from bottom to top. The wireless charging layer 2 includes a coil substrate 202 arranged from bottom to top, multiple closely arranged and arrayed transmitting coils 201 and an insulating layer 203. It also includes a position detection module, which is disposed between the support layer 1 and the wireless charging layer 2, for real-time detection of the movement position of the wireless gaming mouse on the surface layer 3.
[0036] Specifically, the surface layer 3 is woven from high-strength, low-dielectric-constant special polyester fibers or ultra-high molecular weight polyethylene fibers. Utilizing their low resistance to magnetic field penetration, it provides excellent durability and consistent slip. Furthermore, it uses a special polymer coating free of metal ions for hydrophobic and oleophobic treatment to achieve a balance between speed and control suitable for esports. This surface layer forms the working surface for direct movement and operation of the wireless esports mouse, with an operating area marker 301 on its top. The thickness of surface layer 3 is 0.3-0.5mm, and the coefficient of friction of the special polymer coating is between 0.3 and 0.5 to optimize mouse sliding resistance and control precision. Multiple transmitting coils 201 are arranged in a rectangular array, with their center points forming a uniform two-dimensional grid, thus covering most of the effective operating area of the mouse pad without overlap, ensuring that the mouse remains charged during operation.
[0037] In this embodiment, as Figure 2 As shown, the position detection module is the energy recovery layer 5, and also includes an LED light source module 6. The energy recovery layer 5 is disposed between the support layer 1 and the wireless charging layer 2. A magnetic shielding layer 7 is disposed between the energy recovery layer 5 and the wireless charging layer 2. The LED light source module 6 is arranged around the edge of the multi-layer structure. The energy recovery layer 5 can utilize the movement of the gaming mouse and convert its kinetic energy into electrical energy through the principle of electromagnetic induction to power the LED light source module 6, thereby creating a dazzling light effect.
[0038] Among them, such as Figure 4 As shown, the energy recovery layer 5 includes a mounting substrate 501 fixedly connected to the top of the support layer 1 from bottom to top, multiple permanent magnets 502 arranged in a rectangular array on the mounting substrate 501, an isolation layer 504 disposed on the permanent magnets 502, and an energy recovery coil layer 503 disposed on the isolation layer 504. The energy recovery coil layer 503 includes an FPC substrate 5031 and multiple recovery coils 5032 etched on the FPC substrate 5031. The recovery coils 5032 correspond one-to-one with the permanent magnets 502. When the mouse moves on the surface layer 3, the magnets or metal components inside it will disturb the static magnetic field generated by the permanent magnets 502, causing a change in the magnetic flux in the recovery coils 5032, thereby generating an induced current and realizing the conversion of kinetic energy into electrical energy. The FPC substrate 5031 is a flexible printed circuit board; the magnetic shielding layer 7 is made of ferrite or The magnetic field is made of soft magnetic materials such as nanocrystals, with a thickness of 0.5-0.8 mm. It is used to guide the alternating magnetic field of the wireless charging layer 2 to be emitted upward and to block it from interfering with the weak detection signal of the energy recovery layer 5 downward. The thickness of the isolation layer 504 is preferably 0.1-0.2 mm. It is made of polyimide film and is used for electrical insulation and mechanical buffering. In the multiple permanent magnets 502 arranged in a rectangular array, the adjacent permanent magnets 502 are arranged in an alternating N and S pole manner to form a uniform magnetic field gradient. Preferably, the permanent magnet array 502 is composed of multiple axially magnetized cylindrical permanent magnets 502. The axes of all permanent magnets 502 are arranged perpendicular to the surface of the multilayer structure. The adjacent permanent magnets 502 have opposite magnetization directions, so that on the plane of the array, the upper end face of the adjacent permanent magnets 502 presents opposite magnetic poles, that is, the N pole and S pole are arranged alternately.
[0039] like Figure 9 As shown, the LED light source module 6 includes a base 601, an LED light strip 602 is fixedly connected to the base 601, and a transparent protective cover 603 is fixedly connected to the base 601 and sleeved on the outside of the LED light strip 602. The transparent protective cover 603 is made of polycarbonate material and has high light transmittance and impact resistance.
[0040] In this embodiment, as Figure 2As shown, a main control circuit board 4 is fixedly connected to the support layer 1, and an isolation strip 9 is also fixedly connected to the support layer 1. The isolation layer 504 isolates the main control circuit board 4 from the wireless charging layer 2 and the energy recovery layer 5. The isolation strip 9 is made of insulating material such as plastic or rubber to prevent short circuits and electromagnetic interference.
[0041] The main control circuit board 4 serves as the control system for the wireless charging power bank. Its main functions include: 1. Energy scheduling and management: coordinating the power distribution between the two major functional modules, the wireless charging layer 2 and the energy recovery layer 5, to achieve charging and discharging management of the built-in battery, power path optimization, and system power consumption control; 2. Communication and protocol processing: following wireless charging standards such as Qi and the receiving device (in this embodiment, a mouse), performing communication handshakes, negotiating charging power, and executing foreign object detection algorithms to ensure charging safety; 3. Signal processing and positioning: processing and decoding the induction signals from the energy recovery coil layer 503, and tracking the mouse's position on the surface layer 3 in real time by analyzing signal characteristics; 4. Logic control and driving: based on the mouse's position information, driving the activation and deactivation of specific transmitting coils 201 in the wireless charging layer 2 to achieve precise power supply; 5. User interaction and indication: controlling the light emission mode of the LED light source module 6 to display the system status in the form of visual feedback.
[0042] Specifically, on the one hand, the main control circuit board 4 is connected to all the transmitting coils 201 through a multi-channel switch array. This switch array allows the main control circuit board 4 to independently select or turn off any one of the transmitting coils 201 in the array. It is the driving and control center of the transmitting coils 201, determining when and where the mouse is powered and how much power is transmitted. On the other hand, the main control circuit board 4 is connected to all the recycling coils 5032 through an analog front-end circuit. This circuit is used to read the weak induced voltage generated by the magnetic field disturbance of each recycling coil 5032. It serves as the processing and calculation center for the signals of the recycling coils 5032. The array of recycling coils 5032 acts as the "positioning sensor" of the mouse. The main control circuit board 4 obtains the real-time coordinates of the mouse by analyzing the signals of these sensors, which provides a real-time coordinate basis for charging the mouse.
[0043] Finally, to ensure that the wireless charging layer 2 and the energy recovery layer 5, both based on electromagnetic induction, operate stably and without interference within the same device, the main control circuit board 4 employs a time-division multiplexing control strategy. The core of this strategy is to divide time into extremely short cycles. Within each cycle, the system performs only one function—either charging or energy recovery and position detection—ensuring that the two functions are completely staggered in time. Its workflow is as follows:
[0044] 1. The main control circuit board 4 divides a complete working cycle into two non-overlapping time slots: a charging time slot and a detection / recovery time slot. Here, a working cycle of 2ms is used as an example. During the charging time slot, the system focuses on wirelessly charging the mouse. This time slot accounts for 80% of the cycle, or 1.6ms. During the detection / recovery time slot, the system pauses charging and switches to mouse position detection and kinetic energy recovery. This time slot accounts for 20% of the cycle, or 0.4ms.
[0045] 2. The charging time slot workflow is as follows: The main control circuit board 4 sends a control signal to disconnect the connection between the energy recovery coil layer 503 and the detection circuit, and activates one or more transmitting coils 201 directly below or with the strongest signal through the switch array according to the mouse position determined in the previous cycle; at this time, the system operates as a standard wireless charger, the transmitting coil 201 generates an alternating magnetic field to charge the mouse, and the energy recovery system is in a "listening" state during this stage and does not collect signals.
[0046] 3. The detection / recovery time slot workflow is as follows: The main control circuit board 4 shuts down the drive of all transmitting coils 201, and the switching circuit is connected to the energy recovery coil layer 503; at this time, wireless charging stops completely, and the static background magnetic field generated by the permanent magnet 502 is in a stable state. In this state, when the mouse moves, the magnets or metal inside it disturb the background magnetic field. The main control circuit board 4 quickly scans the entire array of recycling coils 5032, reads the changes in the induced voltage of each recycling coil 5032, and accurately calculates the real-time position coordinates of the mouse through algorithms such as the centroid positioning method. During the mouse movement, a weak induced current is generated in the recycling coil 5032. The main control circuit board 4 integrates an energy harvesting circuit to rectify, filter, and boost the weak AC current generated by the recycling coil 5032, and prioritizes its supply to the LED light source module 6. When the LED light source module 6 is not turned on or the required power is lower than the recycling power, excess energy can be stored in the built-in battery or used to reduce the total power consumption of the system. It is collected and used to drive the LED light source module 6 to form a dazzling effect. The main control circuit board 4 stores the calculated new position coordinates as the basis for activating the target transmitting coil 201 in the next charging time slot.
[0047] The preferred lighting effect is one or more of the following: real-time tracking light effect, that is, when the mouse moves, the light in the corresponding area of the LED strip 602 will light up, flow or change color like ripples following the mouse position; kinetic intensity feedback, that is, the brightness, color or flashing frequency of the light is related to the intensity of the mouse movement; system status indication, which displays the system status through preset light colors and modes.
[0048] Specifically: 1. When a mouse containing a magnet or metal moves, it disturbs the static background magnetic field generated by the permanent magnet array 502. According to Faraday's law of electromagnetic induction, this magnetic field disturbance will cause a change in the magnetic flux in the upper recycling coil 5032, thereby inducing a weak induced current in each recycling coil 5032. The faster the mouse moves and the greater the movement amplitude, the stronger the current signal generated.
[0049] 2. During the "detection / recycling time slot," the main control circuit board 4 rapidly scans and reads the induced voltage signals of all recycling coils 5032 through its analog front-end circuit. The main control circuit board 4 analyzes the distribution of these signals using algorithms to accurately calculate the real-time coordinates of the mouse. Simultaneously, it analyzes the average amplitude or power of the signals to determine the kinetic energy intensity of the mouse movement. The main control circuit board 4 combines the position and intensity data with a preset lighting effect mode to generate specific driving instructions for the LED light source module 6. For example: "Display a red flowing water effect at brightness Y in the border area 10 corresponding to coordinate X."
[0050] 3. The induced current generated by the recovery coil 5032 in the first stage is rectified, filtered and boosted by the power harvesting circuit on the main control circuit board 4, and then used to drive the LED light strip 602. The main control circuit board 4 sends the light effect command to the LED light strip 602 through the LED driver IC. The specific LED beads on the LED light strip 602 light up, change color or turn off according to the command, and finally present a dazzling light effect synchronized with the mouse operation.
[0051] The time-division multiplexing switching frequency is extremely high, such as 500Hz. For the mouse receiver, the energy input is continuous and uninterrupted. For the user, the interruption of the charging process is completely imperceptible, realizing a seamless "use and charge at the same time" experience. This avoids the problem of strong charging magnetic fields interfering with weak detection signals from a time perspective.
[0052] In this embodiment, a touch sensing layer 11 is provided at the bottom of the surface layer 3. It is made of transparent ITO conductive film and is used to detect hand touch and control the working mode switching of the LED light source module 6. Preferably, a high-precision sampling resistor and a current sensing amplifier are also provided on the main control circuit board 4 to accurately measure the loop current. At the same time, a resistor voltage divider network is used to monitor the driving voltage. By analyzing the amplitude and phase of these parameters and whether the calculated system impedance deviates from the reference model during normal charging, it is determined whether there is a metal foreign object causing energy loss. Once an abnormality is confirmed, the power supply is immediately stopped and a light warning is issued to realize foreign object detection.
[0053] In this embodiment, as Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, it also includes a frame 10, which is fixedly connected to the outer edge of the multi-layer structure. The frame 10 has a groove 1001, in which the LED light source module 6 is set. The surface of the frame 10 is provided with a power socket 1002, which is directly connected to the main control circuit board 4 through a wire. When the power socket 1002 is connected to an external power adapter, the external mains power is converted into safe low-voltage DC power to provide the basic power required for the operation of the entire system. The frame 10 is made of ABS plastic or aluminum alloy. The width of the groove 1001 matches the LED light source module 6 to ensure a firm fixation.
[0054] In this embodiment, as Figure 5 and Figure 6 As shown, the support layer 1 is a metal plate, preferably made of aluminum alloy. A silicone pad 8 is fixedly connected to the bottom of the support layer 1. A groove 101 is provided at the bottom of the support layer 1. The groove 101 is distributed in a grid pattern to reduce the overall weight and increase the heat dissipation area. The thickness of the silicone pad 8 is preferably 0.5-1.0 mm to provide anti-slip function, so that the aluminum alloy plate is partially exposed to the air and forms an air channel to improve the heat dissipation effect.
[0055] Working principle: When using the wireless charging power bank, the user places it flat on the table and connects its power port 1002 to an external power source via a power cord. Then, a wireless charging gaming mouse is placed on the surface layer 3 of the power bank. The mouse does not need to be precisely aligned with a specific position and can be placed in any operating area of the surface layer 3. At this time, the position detection module starts working, and the permanent magnet 502 in the energy recovery layer 5 generates a static background magnetic field. When the mouse moves on the surface layer 3, its internal magnets or metal components disturb this magnetic field. The recovery coil 5032 in the energy recovery coil layer 503 generates an induction signal due to the magnetic field disturbance. The main control circuit board 4 receives and processes the induction signal and calculates the precise coordinate position of the mouse through a signal analysis algorithm. During use, the main control circuit board 4 employs a time-division multiplexing control strategy. During the charging time slot, the main control circuit board 4 sends a control signal to disconnect the connection between the energy recovery coil layer 503 and the detection circuit. Based on the mouse position determined in the previous cycle, it activates one or more transmitting coils 201 directly below the mouse or with the strongest signal via the switch array. At this time, the system operates as a standard wireless charger, and the transmitting coils 201 generate an alternating magnetic field to charge the mouse. The energy recovery system is in a "listening" state during this phase and does not collect signals. During the detection / recovery time slot, the main control circuit board 4 shuts down the drive of all transmitting coils 201 and switches the circuit to the energy recovery coil layer 503. At this time, wireless charging completely stops, and the static background magnetic field generated by the permanent magnet 502 is in a stable state. In this state, when the mouse moves, its The internal magnets or metals disturb the background magnetic field. The main control circuit board 4 quickly scans the entire array of recycling coils 5032, reads the changes in the induced voltage of each recycling coil 5032, and accurately calculates the real-time position coordinates of the mouse through an algorithm. The main control circuit board 4 stores the calculated new position coordinates as the basis for activating the target transmitting coil 201 in the next charging time slot. At the same time, a weak induced current is generated in the recycling coil 5032 during the mouse movement. The main control circuit board 4 integrates an energy harvesting circuit to rectify, filter, and boost the weak AC power generated by the recycling coil 5032 and supply it to the LED light source module 6 to form a dazzling light effect. Compared with traditional battery replacement or wired charging, this wireless charging power bank can avoid the problem of power interruption breaking the continuity of game operation.
