Description

Floating mouse kit Technical Field

[0001] This application belongs to the field of computer input device technology, and in particular relates to a floating mouse kit. Background Technology

[0002] A mouse is an external input device for computers, serving as a coordinate indicator for the computer's display system. It gets its name from its resemblance to a mouse. The purpose of using a mouse is to simplify and speed up computer operation, replacing the cumbersome commands of the keyboard. A mouse pad, on the other hand, is a small pad placed under the mouse. Its primary function is to prevent reflections and refractions from glass or other special materials from affecting the mouse's sensor positioning. It provides a flat surface for the mouse's sensor system to calculate movement vectors, ensuring the accuracy of these calculations.

[0003] In related technologies, mice position the cursor by sensing the relative movement of a contact surface. Mouse pads provide a recognizable texture for optical mice, improving the feel of operation. In this way of using mice and mouse pads, the hand and wrist need to come into contact with and rub against the mouse pad and the desktop. Prolonged use can easily lead to health problems such as hand and elbow fatigue, shoulder fatigue, and carpal tunnel syndrome. Furthermore, existing mice also suffer from high inertia, which affects the accuracy of operation.

[0004] Currently, researchers are developing lightweight mice, which offer the following advantages: 1. Less effort required for operation, significantly reducing muscle strain: Lighter weight means less force is needed for movement, significantly reducing muscle strain. This greatly improves comfort during extended use, delays fatigue, and is significant from a health perspective. 2. More precise and controlled operation: For example, in games that demand high reaction speed and precision, the mouse needs to instantly match the hand's movement. Lightweight mice allow players to more easily use their upper arm to move the mouse over a wide range for positioning, or to use their wrist for more precise micro-operations. This reduces mouse inertia, making sudden stops easier and more controllable.

[0005] In addition, mice left on the desktop for extended periods can sometimes be damaged by liquids or obstructed by objects, making them difficult to find.

[0006] Therefore, there is an urgent need to redesign a floating mouse kit and overcome the aforementioned shortcomings. Summary of the Invention

[0007] This application provides a floating mouse kit, in which the mouse floats above the mouse pad when not in use, and can be operated by placing your hand on the mouse when in use.

[0008] The first aspect of this application provides a floating mouse kit, which includes a mouse and a mouse pad. The mouse has a first magnet unit inside, which includes at least one first magnetic element. The mouse pad has a second magnet unit inside, which includes one or more second magnetic elements with the same polarity and a third magnetic element. The second magnetic element is a permanent magnet or an electromagnet, and is configured to magnetically repel the first magnetic element. The third magnetic element is an electromagnet, which can generate a magnetic force that attracts or repels the first magnetic element by changing the direction of the current, so that the mouse maintains dynamic balance above the mouse pad.

[0009] Preferably, the magnetic force coverage area of ​​the second magnet unit is greater than that of the first magnet unit.

[0010] Optionally, there may be multiple first magnetic units, and all first magnetic units may have the same polarity arrangement.

[0011] Optionally, the third magnetic monomer surrounds the second magnetic monomer.

[0012] Preferably, the first magnetic unit is a permanent magnet or an electromagnet.

[0013] Preferably, the mouse further includes a first electrical unit, and the mouse pad further includes a second electrical unit. The second electrical unit includes a processing unit and a power adjustment switch. The power adjustment switch is used to control the magnetic force of the electromagnetic unit by adjusting the power supply current in the processing unit and the second magnet unit, thereby controlling the hover height of the mouse. Different hover heights of the mouse can be achieved by adjusting different power levels.

[0014] When the second magnetic unit is an electromagnet, there are multiple of them. Under the influence of voltage and current, they generate an electromagnetic field that repels the first magnetic unit of the mouse. The strength of the electromagnetic field (voltage and current power) is set during the design phase based on the mouse weight and the interaction force between the magnets. For example, a larger required repulsive force results in a larger electromagnetic field strength, and a smaller required repulsive force results in a smaller electromagnetic field strength. The specific magnitude of the electromagnetic field strength needs to be determined based on the subsequent selection of magnet materials and the mouse's hovering distance. Furthermore, preferably, the boundary of the second magnetic unit is provided with magnetic units that attract the first magnetic unit, used to limit the mouse's movement boundaries.

[0015] Preferably, the suspension height ranges from 1 to 50 mm.

[0016] Preferably, the mouse pad also contains a non-magnetic thermally conductive material.

[0017] Preferably, the floating mouse kit further includes a wireless charging base, in which a wireless charging coil is disposed, and also includes a second magnet unit, in which the wireless charging coil is disposed; or the wireless charging coil is disposed above the second magnet unit.

[0018] Preferably, the wireless charging coil is configured for contact or non-contact charging.

[0019] Preferably, the mouse pad and the wireless charging base also include sensors. The sensors are used to collect position data of the mouse when it is hovering in real time and transmit the position data to the processing unit. The processing unit determines electrical parameters based on the deviation between the position data and the hovering height set by the power adjustment switch, and adjusts the magnetic field strength of the second magnet unit based on the electrical parameters so that the mouse is at the set hovering height.

[0020] Preferably, the processing unit is used to acquire the position data, calculate the deviation between the position data and the suspension height set by the power adjustment switch, and perform PWM (pulse width modulation) updates of the electromagnetic unit in the second magnet unit.

[0021] Preferably, there are multiple sensors arranged symmetrically; more preferably, the array formed by the multiple sensors is arranged in the mouse pad.

[0022] This application also provides a method for controlling the hovering height of a mouse in a hovering mouse kit, comprising: S1: Powering on the system, detecting the noise level of the sensor array; if a sensor reading exceeds a preset threshold, marking it and removing the data of that node in subsequent calculations; S2: Reading the current ambient magnetic field and storing it in a register as a bias value, which is used as the base for differential subtraction in subsequent sampling; S3: Initiating hovering: gradually increasing the PWM duty cycle to make the electromagnetic coil current rise according to a ramp function until the mouse force state is detected to reach a preset working point, and adjusting the mouse height.

[0023] Preferably, the method further includes:

[0024] S4: Implement data acquisition and processing: Utilize the PWM center alignment trigger ADC sampling mechanism and set the PWM timer to center alignment mode; when the counter reaches the cycle center or overflow point, the ADC conversion instruction is triggered to achieve zero-phase delay sampling, thereby eliminating the delay.

[0025] Preferably, step S4 includes:

[0026] S41: Acquire the raw voltage signal of the Hall sensor array;

[0027] S42: Use Kalman filtering to process the collected data and output the optimized floating terminal state vector.

[0028] Preferably, during the operation of the method, the magnetic field region is divided into a core driving region, an edge transition region, and a dormant region, wherein levitation force and / or gravity compensation force are provided in the core driving region, a smoothly descending gradient magnetic field is provided in the edge transition region, and no magnetic force is generated in the dormant region, thereby achieving energy saving.

[0029] Preferably, the step of adjusting the mouse height includes: using a sensor installed in the mouse pad to collect the position data of the mouse when it is hovering in real time and transmitting the position data to a processing unit; the processing unit determines electrical parameters based on the deviation between the position data and a preset hovering height; and adjusting the magnetic field strength of the second magnetic unit (electromagnet) and / or the third magnetic unit based on the electrical parameters so that the mouse is positioned at the set hovering height.

[0030] The beneficial effects of this application are as follows:

[0031] This application provides a floating mouse kit, which includes a mouse, a mouse pad, and an optional wireless charging dock. The mouse has a first magnetic unit and a first electrical unit. The first electrical unit provides basic mouse operation functions, such as responding to mouse wheel movements, generating response signals for mouse movement, transmitting these signals to the computer, and controlling the cursor on the computer. The mouse pad and wireless charging dock each have a second magnetic unit and a second electrical unit. The second magnetic units in both the first and second magnetic units have the same magnetism, creating a repulsive force between the mouse and the mouse pad, allowing the mouse to levitate above the mouse pad. The second magnetic unit in this application can be a permanent magnet, an electromagnet, or a combination of both to save power.

[0032] The mouse kit of this application can change the current direction of the third magnetic unit through a control system, thereby generating a magnetic force that attracts or repels the first magnetic unit. This allows the mouse to maintain dynamic balance above the mouse pad, ensuring that the mouse does not drift outside the corresponding operating area of ​​the mouse pad and that the mouse hovers at a preset hovering height. The second electrical unit includes a processing unit and a power adjustment switch. The power adjustment switch can include multiple hovering distance setting levels. After operating the power adjustment switch, the processing unit can output a corresponding current to the second or third magnetic unit in the second magnetic unit based on the hovering distance setting signal of the power adjustment switch. The second and third magnetic units can then output corresponding magnetic forces to adjust the hovering height of the mouse. In this way, the mouse does not contact the mouse pad when not in use, reducing dust accumulation and preventing contamination from water and other liquids on the desktop, thus extending the mouse's lifespan. This application realizes a zero-gravity mouse, reducing hand and wrist pressure and solving the health problems caused by using traditional mice.

[0033] Furthermore, the mouse of this application achieves magnetic levitation positioning without the need for horizontal obstructions or limiting devices, resulting in a simple structure. In addition, the kit includes a wireless charging dock outside the mouse pad, allowing the mouse to be charged during use, adding a stylish touch, and also providing convenient storage. Optionally, a third charging unit can be added to the wireless charging dock, integrating other functions such as a hub or Bluetooth speaker.

[0034] In addition, users usually wait until the low battery warning light comes on when using a regular wireless mouse before they remember to charge it. However, the magnetic levitation charging base provided in the embodiments of this application can be used as a mouse base station. When not in use, the mouse can be stored on the base while being charged, avoiding the need for emergency charging. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0047] It should be noted that in the description of this application, "at least one" refers to one or more, where "multiple" refers to two or more. Furthermore, it should be understood that in the description of this application, terms such as "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or order.

[0048] This application provides a floating mouse kit, which includes a mouse, a mouse pad, and a wireless charging base. When not in use, the mouse can float a certain distance above the mouse pad. Removing the mouse reduces the operational pressure on the wrist, hand, and shoulder, eliminating the health effects of mouse operation as described in existing technologies. To use, simply place your hand on the mouse to begin operation. After use, suspend the mouse within the magnetic field; releasing your hand will automatically return the mouse to its original position, preventing it from slipping away and being lost.

[0049] Specifically, the mouse kit includes a magnetic levitation component. The mouse comprises a first magnetic unit, which includes one or more first magnetic units. When there are multiple first magnetic units, all first magnetic units have the same polarity. The mouse pad includes a second magnetic unit, which includes one or more second magnetic units, and optionally, a third magnetic unit. When there are multiple second magnetic units, they are symmetrically arranged; the multiple third magnetic units are also symmetrically arranged. This symmetrical arrangement allows the repulsive and attractive forces to balance each other, enabling the mouse to float stably on the pad and, when stationary, to be positioned above the center of symmetry of either the second or third magnetic unit.

[0050] Specifically, the first and second magnetic units can both be permanent magnets or electromagnets, and the third magnetic unit is an electromagnet, and the magnetic field direction of the third electromagnet can be adjusted by changing the direction of the current in the coil.

[0051] In one embodiment, the first and second magnetic units are both permanent magnets, and the third magnetic unit is an electromagnet. The second and first magnetic units repel each other, generating an upward thrust that balances the mouse's own weight. In another embodiment, the third magnetic unit generates an attractive force with the first magnetic unit, and is positioned outside and surrounds the second magnetic unit. The third magnetic unit defines the magnetic boundary of the mouse pad, thus fixing the mouse within a preset range. If the mouse is placed within the magnetic range of the second magnetic unit in the mouse pad, the first magnetic unit will be automatically attracted and suspended in a fixed position.

[0052] In one embodiment, there may be multiple second magnetic units, some of which are permanent magnets and others are electromagnets.

[0053] Furthermore, the wireless charging base also includes a wireless charging coil for charging electronic products (including a charging mouse) placed on the mouse pad. The wireless charging coil can be located above the second or third magnetic unit, or within the second or third magnetic unit, or it can be configured as an electromagnetic coil that also has wireless charging functionality.

[0054] Specifically, the wireless charging dock can be set to either contact or contactless charging modes.

[0055] In a specific embodiment, the mouse pad is also equipped with a power adjustment switch. This power adjustment switch can control the magnitude of the power supply current to the second magnetic unit, thereby controlling the magnetic force of the second magnetic unit and thus controlling the hovering height of the mouse. By adjusting different power levels, different hovering heights of the mouse can be achieved, which can improve the comfort and convenience of using the mouse.

[0056] Figures 1 and 2 show a floating mouse kit provided in an embodiment of this application. The floating mouse kit includes a mouse 3 and a mouse pad 5. The mouse 3 is provided with a first magnet unit 1 and a first electrical unit, and the mouse pad 5 is provided with a second magnet unit 4 and a second electrical unit.

[0057] Figures 3-5 show another embodiment of this application, wherein the floating mouse kit includes a mouse 3, a mouse pad 5, and a wireless charging base 6.

[0058] Figures 6 and 7 show the arrangement of the second magnetic monomers 41 in different embodiments of this application. In both embodiments, the second magnetic monomers 41 provide an upward repulsive force to the mouse.

[0059] When the second magnetic unit 41 is an electromagnet, it will generate an electromagnetic field under the action of voltage and current, which will repel the first magnetic unit of the mouse. At the same time, the third magnetic unit will generate a repulsive or attractive force with the first magnetic unit through the action of the electromagnetic field. The strength of the electromagnetic field (voltage and current power) will be set in the design stage according to the interaction force between the magnetic fields. For example, if the required mutual repulsion force is large, the electromagnetic field strength will be large, and if the required mutual repulsion force is small, the electromagnetic field strength will be small. The specific magnitude of the electromagnetic field strength needs to be set according to the selection of magnet materials and the mouse hovering distance.

[0060] Figures 8-11 provide another embodiment of this application, in which the second magnetic unit 4 in the mouse pad includes two sets of second magnetic units 41 and third magnetic units 42 with opposite polarities. The second electrical unit includes a processing unit and a power adjustment switch. After being powered on by the second electrical unit, the magnetic poles of the second magnetic unit 41 are set to repel each other from the first magnetic unit 1. The power adjustment switch is used to adjust the hover height of the mouse based on the processing unit and the second magnetic unit 41.

[0061] In addition, the mouse also includes conventional functional structures, as shown in Figures 1 and 2, such as the scroll wheel, left button, and right button.

[0062] In one embodiment, the first electrical unit of the mouse includes a transmitter, a photosensitive sensor, a serial communication interface, and other corresponding components. The first electrical unit also has a first power supply interface, which can be used to power the mouse, and / or, the first power supply unit also has a power storage unit. The specific components and parts included in the mouse are not limited here and can be configured as needed.

[0063] In one embodiment, the shape of the mouse can be as shown in Figures 1 and 2, or it can be other shapes. It should be noted that Figure 1 provided in this embodiment is only used to clearly illustrate the solution and does not limit the specific settings of the solution.

[0064] In one embodiment, the first magnet unit 1 can be disposed on the bottom of the mouse, either exposed or not exposed. The first magnet unit 1 includes one or more first magnetic individual units, which, when multiple are present, are arranged with the same polarity. Preferably, the first magnetic individual unit is a permanent magnet.

[0065] In one embodiment, the mouse pad 5 includes a second magnet unit 4 and a second electric unit, as shown in Figure 2. After the mouse is magnetically levitated and fixed, it is positioned above the second magnet unit 4. The second magnet unit includes a second magnetic unit 41 and a third magnetic unit 42, arranged as shown in Figures 6-11. Specifically, the second magnetic unit 41 is located in the inner circle and is an electromagnet that repels the first magnet unit. The third magnetic unit 42 is an electromagnet located around the second magnetic unit 42. It can include electromagnets, electromagnetic coils, inductors, or other electrically charged magnetic materials or components. When energized, the third magnetic unit 42 generates an attractive force on the first magnet unit. By adjusting the attractive force of all the third magnetic units 42, the mouse can be levitated and stay at a preset position.

[0066] Specifically, there is no limit to the number of the second magnetic unit 41, which can be arranged into symmetrical structures such as squares and rhombuses, as shown in Figure 7-9, thereby achieving planar balance of forces.

[0067] In one embodiment, a built-in power adjustment switch inside the mouse pad can adjust the mouse's hover height according to the user's preferences or needs, making it convenient for the user to grab the mouse at any time.

[0068] In the aforementioned hovering mouse kit, after the mouse pad is charged and powered on, when the mouse is placed above the mouse pad, the first magnetic unit of the mouse and the second magnetic unit of the second magnetic unit of the mouse pad generate a repulsive force, and the mouse floats up under the action of the repulsive force.

[0069] Specifically, the hover mouse kit of this application features a zero-gravity / constant buoyancy compensation control mode. In this mode, magnetic force is used to counteract the mouse's own weight, achieving a "zero-gravity" feel and reducing wrist strain. Specifically, the control system detects the total weight G of the mouse and then sets a basic expected buoyancy F. b The buoyancy is slightly less than or equal to the total weight of the mouse, and a constant upward lifting force on the mouse is maintained through a gravity compensation system; so that the control system can provide continuous stress relief support for the wrist whether the mouse is stationary or moving.

[0070] Specifically, the hover mouse kit of this application includes the following components in its processing system: 1) a state observation module responsible for data fusion and filtering from multiple sensors; 2) a motion control algorithm module handling PID feedback, pre-motion feedback, and zero-gravity compensation control; 3) a power allocation module for sparse matrix driving and PWM waveform generation, used to control and allocate the power of the coils; and 4) a timing synchronization and anti-interference module responsible for ADC and PWM synchronization and time-division multiplexing for wireless charging. This processing system employs a high-frequency control cycle at the kHz level (e.g., microseconds / cycle) and achieves stable six-degree-of-freedom or three-degree-of-freedom control of the mouse through a real-time "perception-decision-execution" link.

[0071] Specifically, the magnetic levitation control process of the mouse includes the following steps:

[0072] S1: After the system is powered on, the noise level of the sensor array is first detected. If a sensor reading exceeds the preset threshold, it is marked and the data of that node is removed in subsequent calculations.

[0073] S2: Read the current ambient magnetic field and store it in the register as B. offset This serves as a bias value, which is used as the base for differential subtraction in subsequent sampling.

[0074] S3: Start Floating: Gradually increase the PWM duty cycle so that the electromagnetic coil current rises according to the ramp function until the mouse force state is detected to reach the preset operating point, and the system enters the closed-loop maintenance state.

[0075] Furthermore, the control step may also include:

[0076] S4: Implement data collection and processing:

[0077] A PWM center-aligned trigger ADC sampling mechanism is used, setting the PWM timer to center-aligned mode. When the counter reaches the center of the cycle or the overflow point, the ADC conversion instruction is triggered to achieve zero-phase-delay sampling, thereby eliminating the delay. This step ensures that the sampling time corresponds to the average value of the current waveform, minimizing switching noise interference.

[0078] This step also includes:

[0079] S41: Acquire the raw voltage signal of the Hall sensor array;

[0080] S42: The collected data is processed using a Kalman filter to output the optimized state vector of the floating terminal.

[0081] The operation also includes the following steps: dividing the activated magnetic area into a core driving area, an edge transition area, and a dormant area. The core driving area provides the main levitation force or gravity compensation force, the edge transition area provides a smooth downward magnetic field gradient to avoid movement vibration, and the dormant area has no magnetic force generated and no power consumption, thereby achieving energy saving.

[0082] The control process described in this application incorporates a composite control strategy: an incremental PID algorithm is used to adjust and maintain the Z-axis height and attitude angle to ensure stability of height and angle; and kinematic prediction compensation is implemented: to address the "drag" and "hysteresis effect" during rapid mouse movement, the electromagnetic field parameters are pre-adjusted by predicting the position at the next time point, ensuring that the center of the magnetic field is always aligned with or slightly ahead of the physical center of the mouse. For example, when the user stops abruptly, the acceleration reverses instantaneously, and the control system generates a corresponding reverse braking magnetic field to assist the mouse in stopping more stably, preventing it from rushing out of the effective magnetic field area due to inertia.

[0083] In addition, the control system increases the current density of the coil in front of the movement in advance according to the direction of the velocity vector, and generates a reverse braking magnetic field in the coil behind the movement to actively counteract the tilting or lag of the suspended body caused by inertia, thus achieving "zero delay" following.

[0084] The time-division multiplexing described in this application refers to dividing continuous time into tiny segments, allowing each task to take turns exclusively using the system. Specifically, in the wireless charging base, the following timing logic is adopted to address the magnetic field coupling interference between the magnetic levitation coil and the wireless charging coil: A. Period segmentation: The control period is divided into a charging window and a sensing window. B. Logic execution: For example, during the sensing window, the MCU cuts off the charging magnetic field and delays for eddy current decay; then it triggers ADC sampling to obtain a clean levitation position signal; after sampling, it enters the charging window to perform wireless charging. This achieves a state where charging and levitation coexist.

[0085] In addition, the control method of this application also sets a virtual haptic boundary to prevent the mouse from sliding out of the effective area of ​​the base. Specifically, the control system calculates the Euclidean distance from the mouse to the boundary of the effective area in real time. When the Euclidean distance is less than the safe distance, the control system generates a reverse virtual force pointing towards the center.

[0086] In the above embodiments, the mouse mainly achieves levitation based on the repulsive force between the second magnetic units in the first and second magnetic units.

[0087] In another embodiment, a sensor inside the mouse pad can detect changes in the magnetic field. Under the influence of the electromagnetic field of the third magnetic unit, a certain attraction force is applied to the first magnetic unit of the mouse due to the attraction of opposite magnetic fields, thus fixing the mouse in a suspended position.

[0088] The floating mouse kit of this application allows the mouse to levitate on the mouse pad without any external force in the horizontal direction; in addition, when the mouse moves from above the mouse pad to above the wireless charging base, and when the mouse is placed within the magnetic range of the charging base, it can be automatically attracted and levitate at a specific position.

[0089] Specifically, when there are one or more third magnetic units, they should be arranged symmetrically to achieve horizontal plane balance of gravity. The layout is symmetrical, based on one or more of the horizontal center line, vertical center line, and diagonal lines of the mousepad surface, with the magnetic components and electromagnetic coils arranged symmetrically.

[0090] Figure 8 shows a layout schematic diagram provided by an embodiment of this application. The shaded circular pattern represents a third magnetic unit 42 with a magnetic field different from that of the first magnetic unit, and the unshaded circular pattern with a cross pattern represents a second magnetic unit 41 with the same magnetic field as the first magnetic unit. It can be seen that, based on any one or more of the horizontal center line, vertical center line, and diagonal lines of the mouse pad surface, the second magnetic unit 41 and the third magnetic unit 42 are symmetrically arranged. This ensures that the magnetic field force at symmetrical positions is the same. Figure 9 shows a perspective view of the above layout schematic diagram provided by an embodiment of this application.

[0091] Figure 10 shows a schematic diagram of the layout of another second magnetic unit 41 and a third magnetic unit 42 provided in an embodiment of this application.

[0092] Using the above-described layout of the electromagnetic coil and magnetic components, the mouse can be placed on the mouse pad surface when the electromagnetic coil is not energized. When the electromagnetic coil is energized, the mouse can hover above the mouse pad at a set height, as shown in Figure 5. For example, the hover height can be adjusted to 40mm or 50mm by the power adjustment switch.

[0093] Preferably, the mouse pad also incorporates a non-magnetic thermally conductive material. This means that when the mouse hovers, the mouse pad generates heat, which can be dissipated using a non-magnetic thermally conductive material. This prevents the mouse pad from overheating and affecting the operation of the magnetic components and other related parts, thus ensuring the accuracy of the mouse pad's operation.

[0094] In a specific embodiment, the processing unit of the second electrical unit of the mouse pad includes a sensor. The sensor is used to collect position data of the mouse when it is hovering in real time, so that the processing unit determines the electrical parameters based on the deviation between the position data fed back by the sensor and the hovering height set by the power adjustment switch, and adjusts the magnetic field of the third magnetic unit based on the electrical parameters so that the mouse is at the hovering height set by the power adjustment switch.

[0095] In other words, when the mouse is placed on the mouse pad, the first magnetic unit in the mouse causes a change in the magnetic field above the mouse pad, which is detected by the sensor on the mouse pad. The sensor transmits the detected magnetic field data to the processing unit. The processing unit determines the corresponding electrical parameters (current, voltage, power) to the third magnetic unit based on the levitation height set by the power adjustment switch, such as 50mm. This causes the third magnetic unit to generate a magnetic field, which in turn generates a pulling force that attracts the first magnetic unit in the mouse, "pulling" the mouse within the set range and fixing it at the set height for levitation.

[0096] In one embodiment, the processing unit in the mouse pad is used to complete the acquisition of position data, the deviation calculation of position data from the floating height set by the power adjustment switch, and the PWM update of the third magnetic unit in each operating control cycle.

[0097] In one embodiment, the mouse pad's sensors collect real-time position data and attitude angles of the hovering mouse above the mouse pad along the X / Y / Z axes. Based on the deviation between the real-time position feedback from the sensors and the hovering height set by the power adjustment switch, the processing unit generates a signal to adjust the current, voltage, and power of the electromagnet, producing a controllable gradient magnetic field. The calculation can employ an incremental PID algorithm, where the proportional coefficient Kp is used for rapid response to position changes, the integral time Ti eliminates steady-state errors, and the derivative time Td suppresses oscillations. Alternatively, a current sensor can detect the actual current of the electromagnet, comparing it with the expected current output from the electromagnetic coil. The PID algorithm then precisely controls the PWM duty cycle to ensure the linearity of the electromagnetic force output. The algorithm runs at a 5kHz frequency, completing data acquisition, algorithm calculation, and PWM update in each control cycle. Upon receiving a switch and height command, the system generates acceleration / deceleration curves to achieve lifting and lowering. The operating state can be activated via a switch, and the hovering height can be adjusted within a range of 1-50mm by generating corresponding power from the electromagnetic coil.

[0098] In one embodiment, the mouse may also contain a sensor and a circuit board.

[0099] In one embodiment, the mouse pad has a built-in output power adjustment switch. By adjusting this switch, the sensor can detect changes in the magnetic field, causing the mouse to float up and down within a certain range.

[0100] In one embodiment, the mouse pad contains a plurality of evenly arranged sensors, as shown in Figure 12. In a preferred embodiment, the second magnetic units in the mouse pad are arranged in a cross shape, and the plurality of sensors are arranged in a corresponding cross shape. The circled areas in the figure indicate the positions of the sensors, as shown in Figure 13.

[0101] In one embodiment, the sensors can be evenly distributed on the mouse pad. There are no restrictions on the specific arrangement of the sensors; they can be set as needed.

[0102] In one embodiment, the mouse can levitate within 70mm in the air due to the combined forces of the repulsion between like poles of the magnetic field and the attraction between opposite poles of the electromagnetic field within the mouse pad, caused by the action and reaction of magnets within the mouse and mouse pad.

[0103] In one embodiment, it is understood that in the floating mouse kit of this application, the height at which the mouse can float can be set based on the power adjustment switch set in the mouse pad. For example, the power adjustment switch can be set with 4 levels, and the floating heights of the 4 levels are 20, 40, 50, and 70 respectively. Alternatively, the power adjustment switch can be set as a scroll wheel. By tossing the scroll wheel of the power adjustment switch, the power supply current to the third magnetic unit can be adjusted, so that the magnetic force of the third magnetic unit can be increased or decreased, and any height from 1mm to 70mm can be achieved, preferably 1-50mm.

[0104] In one embodiment, the mouse can levitate within 50mm in the air due to the combined forces of the repulsion between like magnetic fields and the attraction between opposite electromagnetic fields within the mouse pad, caused by the interaction of magnets within the mouse and mouse pad.

[0105] Specifically, the first electrical unit of the floating mouse kit in this application embodiment includes a first power supply interface, and the second electrical unit includes a second power supply interface.

[0106] In one embodiment, the first power supply interface and the second power supply interface are USB Type-C interfaces, or other interface types, such as Lightning interfaces, USB Mini interfaces, etc. There is no specific limitation on the form of the first and second power supply interfaces; they can be set as needed.

[0107] In one embodiment, as shown in FIG14, it is a three-dimensional schematic diagram of the floating mouse kit provided in the embodiment of this application.

[0108] Figure 15 shows an embodiment of the floating mouse kit of this application, wherein the upper surface of the mouse pad 5 is a circular structure, the mouse 3 is provided with a first magnet unit 1 and a first electrical unit, and the mouse pad 5 is provided with a second magnet unit 4 and a second electrical unit, wherein the second magnet unit 4 includes two sets of second magnetic units 41 and third magnetic units 42 with opposite polarities. The adjustment switch 51 is used to adjust the hovering height of the mouse based on the electrical processing unit and the third magnetic unit 42.

[0109] In addition, the mouse also includes conventional functional structures such as scroll wheel 2, left button, right button and side buttons.

[0110] In one embodiment, the mouse can be a wirelessly charged mouse, and the mouse pad can wirelessly charge it.

[0111] In one embodiment, the first magnet unit 1 can be exposed on the bottom of the mouse or disposed on the bottom of the mouse without being exposed. The first magnet unit 1 includes one or more permanent magnets, and when there are multiple permanent magnets, the permanent magnets are configured with the same polarity.

[0112] Figure 16 shows the internal structure of the wireless charging pad, which includes a charging coil 52 located above the third magnetic unit 42. This mouse pad can wirelessly charge other electronic devices, including wireless charging mice, etc.

[0113] In one embodiment, for the coil structure inside the mouse pad shown in Figures 9 and 10, the third magnetic unit 42 can also function as a wireless charging device, which makes the internal space smaller and the structure more compact.

[0114] The advantages of this application are:

[0115] 1. The magnetic levitation mouse kit uses the repulsion between the permanent magnet of the mouse and the electromagnet of the mouse pad to make the mouse float. The levitation height of the mouse is controlled by controlling the current. Then, the electromagnetic field in the mouse pad forms the required attraction with the mouse, fixing the mouse within a certain levitation height.

[0116] 2. By adjusting the output power adjustment switch inside the mouse pad, the mouse can float up and down within a certain height, and the hovering height can be set by the user.

[0117] 3. At the same time, the application of magnetic levitation technology has brought a revolutionary breakthrough to mouse design. Magnetic levitation technology uses magnetic force to levitate and move objects.

[0118] 4. Furthermore, future office environments will place greater emphasis on intelligence and efficiency. As a representative of high-tech products, the magnetic levitation mouse not only meets users' needs for comfortable mouse operation but also showcases the innovative trends and limitless possibilities of future office equipment.
