In order to solve the above technical problems, the utility model provides a wirelessly rechargeable mouse, including:

[0030] Mouse body 1;

[0031] The receiving coil T2 is used to receive the energy transmitted by the transmitting coil T1 based on the power supply;

[0032] The power conversion circuit 2 has an input end connected to the output end of the receiving coil T2, and is used to convert the energy received by the receiving coil T2 into a charging voltage, and output the charging voltage to the battery module BAT;

[0033] The battery module BAT has an input end connected to an output end of the power conversion circuit 2 and is used to supply power to the mouse body 1 .

[0034] Specifically, the wireless charging process utilizes the principle of electromagnetic induction. There is a coil at the transmitting end and the receiving end respectively. The coil at the transmitting end is called the transmitting coil T1, and the coil at the receiving end is called the receiving coil T2. The receiving coil T2 matches the transmitting coil T1. The transmitting coil T1 serves as the primary coil, and the receiving coil T2 serves as the secondary coil corresponding to the primary coil. When an alternating current of a certain frequency is passed through the primary coil, a certain current will be generated in the secondary coil due to electromagnetic induction, thereby transferring energy from the transmitting end to the receiving end. In this application, the receiving coil T2 is set inside the mouse. When a certain power supply is passed through the transmitting coil T1 matching the receiving coil T2, the receiving coil T2 in the mouse can receive the energy generated by the electromagnetic induction process. The energy received by the receiving coil T2 can be output to the power conversion module, and converted into the charging voltage required by the battery module BAT through the power conversion module. The battery module BAT is charged using the charging voltage, so that the mouse body 1 can perform a normal working process based on the charged battery module BAT.

[0035] It is not difficult to understand that the mouse body 1 is the working circuit for the mouse to move, click, and perform other work processes on the computer device. It can be implemented in the form of an integrated circuit or other circuit integrated on a PCB (printed circuit board). The mouse body 1 may include a photoelectric sensor and an optical navigation engine. The photoelectric sensor can collect the movement direction of the mouse, and the optical navigation engine can convert the direction information into coordinates to indicate the movement of the mouse; the battery module BAT is usually implemented in the form of a battery cell; the specific types and implementation methods of the mouse body 1, receiving coil T2, power conversion circuit 2, and battery module BAT are not particularly limited in this application, and can be determined and adjusted according to factors such as the application requirements of the mouse in actual applications.

[0036] It can be understood that the present application provides a mouse that supports wireless charging function, which allows users to charge conveniently and reduces the usual charging plugging and unplugging process; it realizes the function of wireless charging of the mouse, and the charging process can be carried out through the simple operation of placement, allowing users to charge conveniently when not in use, and the mouse is always fully charged, thereby improving the user experience.

[0037] The utility model provides a wirelessly rechargeable mouse, which obtains energy through a receiving coil T2 connected to a transmitting coil T1, and uses a power conversion circuit 2 connected to a battery module BAT to convert the energy obtained by the receiving coil T2 into a charging voltage that can be normally used by the battery module BAT, thereby realizing the wireless charging process of the battery module BAT, so as to provide a normal working power supply for the mouse body 1, and no wired connection is required between the receiving coil T2 and the transmitting coil T1, and energy generation can be achieved by only generating electromagnetic induction. Therefore, the mouse can be wirelessly charged by using the electromagnetic induction between the receiving coil T2 and the transmitting coil T1 in a wireless situation, thereby realizing the wireless charging function of the mouse, making it convenient for users to charge at any time, reducing the usual charging plugging and unplugging process, avoiding the impact of the plugging and unplugging process on the life of the mouse itself, and thus improving the user experience.

[0038] Based on the above embodiments:

[0039] As an optional embodiment, the power conversion circuit 2 includes a rectifier module and a buck-boost module, the input end of the rectifier module is connected to the output end of the receiving coil T2, the output end is connected to the input end of the buck-boost module, and the output end of the buck-boost module is connected to the input end of the battery module BAT;

[0040] The rectifier module is used to convert the energy received by the receiving coil T2 into a DC voltage;

[0041] The buck-boost module is used to convert the DC voltage into the charging voltage required by the battery module BAT.

[0042] It is not difficult to understand that the energy generated by electromagnetic induction and received by the receiving coil T2 will exist in the form of alternating current, and the battery module BAT in the mouse usually requires direct current for charging. Therefore, after the receiving coil T2 receives the energy, the rectifier module in the power conversion circuit 2 is first required to convert the alternating current into direct current. The DC voltage obtained may have a voltage specification difference with the power supply required by the battery module BAT. At this time, it is necessary to further convert the obtained DC voltage into a charging voltage with the same power supply specification as the battery module BAT through the buck-boost module, so as to realize the normal charging process of the battery module BAT by the charging voltage. The specific types and implementation methods of the rectifier module and the buck-boost module are not particularly limited in this application. The rectifier module can be implemented by a rectifier circuit such as a full-bridge rectifier bridge or a half-bridge rectifier bridge. The buck-boost module includes a buck circuit and a boost circuit, which can be selected and adjusted according to the actual application. The power conversion circuit 2 can also first convert the energy received by the receiving coil T2 into an alternating current with a voltage specification corresponding to the power supply required by the battery module BAT, and then convert it into a DC charging voltage through the rectifier module, which is not limited to the specific implementation method described in this embodiment.

[0043] Specifically, considering that the energy received by the receiving coil T2 is alternating current, the power conversion circuit 2 includes a rectifier module and a buck-boost module, which first converts the alternating current into a direct current voltage and then adjusts the voltage specification of the direct current voltage, thereby effectively realizing the charging voltage required by the battery module BAT, ensuring that the energy received by the receiving coil T2 can be accurately and effectively charged into the battery module BAT, thereby improving the accuracy and reliability of the entire charging process.

[0044] As an optional embodiment, the rectifier module includes a first diode D1, a second diode D2, a third diode D3, a fourth diode D4 and a first capacitor C1, the anode of the first diode D1 is respectively connected to the first output end of the receiving coil T2 and the cathode of the second diode D2, and the cathode is respectively connected to the cathode of the third diode D3, the first end of the first capacitor C1 and the input end of the buck-boost module, the anode of the second diode D2 is grounded and respectively connected to the anode of the fourth diode D4 and the second end of the first capacitor C1, and the anode of the third diode D3 is respectively connected to the second output end of the receiving coil T2 and the cathode of the fourth diode D4.

[0045] It is not difficult to understand that the rectifier module can be implemented by a bridge rectifier circuit including a first diode D1, a second diode D2, a third diode D3, a fourth diode D4 and a first capacitor C1. The unidirectional conduction principle of the diode can effectively realize the rectification process of the alternating current. The first capacitor C1 can smooth the output voltage of the bridge rectifier circuit, and convert the pulsating direct current into smooth direct current, so that the output voltage is more stable. At the same time, the first capacitor C1 can also play a filtering role, reduce noise, and improve the anti-interference ability of the entire circuit. The specific types and implementation methods of the first diode D1, the second diode D2, the third diode D3, the fourth diode D4 and the first capacitor C1 are not particularly limited in this application, and the diode can also be replaced by other types of unidirectional conduction modules.

[0046] Specifically, the bridge rectifier circuit including the first diode D1, the second diode D2, the third diode D3, the fourth diode D4 and the first capacitor C1 can effectively realize the rectification function of the rectifier module through the unidirectional conduction principle of the diode. The circuit structure of the entire rectifier module is simple and easy to implement. The components used are low in cost and small in size, which is conducive to the simple implementation of the entire mouse, reduces the cost and volume of the entire mouse, and is convenient for application and promotion.

[0047] As an optional embodiment, the rectifier module further includes a second capacitor C2, a first end of the second capacitor C2 is connected to the first output end of the receiving coil T2, and a second end is respectively connected to the anode of the first diode D1 and the cathode of the second diode D2.

[0048] It is not difficult to understand that a second capacitor C2 can be added on the input side of the rectifier module to serve as a coupling capacitor for isolation, so as to prevent the electromagnetic induction between the transmitting coil T1 and the receiving coil T2 from affecting the normal operation of the rectifier module, so that the working points between the front and rear stage circuits do not affect each other. The specific type and implementation method of the second capacitor C2 are not particularly limited in this application, and it can be implemented using capacitors such as non-polar capacitors.

[0049] Specifically, a second capacitor C2 can be added on the input side of the rectifier module to isolate the receiving coil T2 and the rectifier module from each other to avoid mutual influence. The components used have a simple structure, are easy to implement, low cost, and small size, which is conducive to the simple implementation of the entire mouse, reduces the cost and size of the entire mouse, and facilitates application and promotion.

[0050] As an optional embodiment, the wirelessly rechargeable mouse further includes a linear voltage regulator, the input end of the linear voltage regulator is connected to the first end of the first capacitor C1, the output end is connected to the input end of the buck-boost module, and the ground end is grounded.

[0051] It is not difficult to understand that in order to improve the stability of the DC voltage output from the rectifier module to the buck-boost module, a linear voltage regulator may be further provided between the rectifier module and the buck-boost module. The linear voltage regulator may further stabilize the DC voltage output from the rectifier module to the buck-boost module, thereby improving the accuracy and reliability of the boost or buck process of the buck-boost module. The specific type and implementation method of the linear voltage regulator are not particularly limited in this application. Other types of voltage regulator modules such as Zener diodes may also be used for implementation, and are not limited to the specific implementation method described in this embodiment.

[0052] Specifically, further adding a linear voltage regulator between the rectifier module and the buck-boost module can further improve the stability of the DC voltage output from the rectifier module to the buck-boost module, ensuring the stability and reliability of the final charging voltage, thereby further ensuring the stable charging process of the battery module BAT and ensuring the safety and reliability of the entire mouse.

[0053] As an optional embodiment, the wirelessly rechargeable mouse further includes a first bearing structure and a first magnet mounted on the first bearing structure, wherein the first bearing structure is a bearing structure of the receiving coil T2;

[0054] The first bearing structure is used to be attracted to the second bearing structure through the first magnet and the second magnet; the second bearing structure is the bearing structure of the transmitting coil T1, and the second magnet is arranged on the second bearing structure.

[0055] It is not difficult to understand that in order to further facilitate the use of the user, the mouse can be further provided with a magnetic attraction function. The magnetic wireless charging mouse can quickly align the receiving coil T2 with the transmitting coil T1 through the attraction process between the first magnet on the first bearing structure and the second magnet on the second bearing structure, and form a stable fixed relationship with the transmitting coil T1. At the same time, the first magnet and the second magnet can also play a positioning role. By setting the first magnet and the second magnet at the corresponding position that is exactly the same as the relative position between the coils, the user can quickly and accurately align the transmitting coil T1 with the receiving coil T2, which is conducive to the effective implementation of the electromagnetic induction process. The present application does not make any special restrictions on the arrangement positions and the number of the first magnet and the second magnet. The number of the first magnet and the second magnet can be consistent. For example, when two magnets are arranged on the first bearing structure as the first magnets, two magnets are also arranged on the second bearing structure as the second magnets. The number of the first magnet and the second magnet can be 2, 4, 6, 8, etc., which can be adjusted according to the shape and size of the corresponding bearing structure. The shape of the magnets used can be circular, rectangular or polygonal, and there are many implementation methods. The present application does not make any special restrictions on the specific types and implementation methods of the first bearing structure and the second bearing structure. In order to reduce the volume and cost, the first bearing structure and the second bearing structure can be arranged as thin sheets. At the same time, in order to ensure the accurate implementation of the charging process, the shape and size of the first bearing structure and the second bearing structure can be consistent. For example, the first bearing structure and the second bearing structure are arranged as rectangular thin sheets with the same shape and size, and the transmitting coil T1 and the receiving coil T2 are arranged inside these two identical rectangular thin sheets. At the same time, the first magnet and the second magnet are arranged at the same position of the four corners of the two rectangular thin sheets to ensure that the transmitting coil T1 and the receiving coil T2 can be completely aligned after being magnetically fixed.

[0056] Specifically, in order to facilitate use and fixation, a magnetic attraction function can be further added to the mouse, and the attraction between the first magnet and the second magnet is used to realize the alignment and fixation process between the transmitting coil T1 and the receiving coil T2. The user does not need to repeatedly adjust the position, and the magnet setting is directly used to realize the placement process of the mouse during wireless charging, further improving the user experience.

[0057] As an optional embodiment, a charging interface is further included, which is connected to the input end of the power conversion circuit 2 and is used to charge the battery module BAT through an external power source via a power line.

[0058] It is understandable that, on the basis of wireless charging, a charging interface can be further provided on the mouse, so that the mouse supports both wired charging and wireless charging functions, thereby expanding the application scope of the entire mouse, improving the flexibility of the user's use process, and facilitating the user to flexibly adjust the charging method according to their actual application situation. The specific type and implementation method of the charging interface are not particularly limited in this application.

[0059] As a specific embodiment, the wirelessly rechargeable mouse includes a receiving coil T2, a wireless charging conversion circuit as a rectifier module, a positioning magnet, a working circuit of the mouse body 1, a battery protection circuit, a voltage conversion circuit as a buck-boost module, a battery, and a Type-C port as a charging interface, such as Figure 2 and Figure 3 As shown, a DC power supply is input to the transmitting end, and the DC power supply generates an AC voltage at the output end of the power full bridge through a power amplifier. The AC voltage can exist in the form of a square wave; the square wave is loaded on both ends of the LC Tank, that is, both ends of the third capacitor C3 to generate an AC current; the AC current generates a magnetic field through the transmitting coil T1; the receiving coil T2 at the receiving end senses this magnetic field, and generates an AC current at the receiving end LC Tank, that is, both ends of the second capacitor C2; the AC current is converted into a DC voltage through a rectifier bridge; the DC voltage charges the battery through an LDO (low dropout regulator) and a Charger circuit, and the Charger circuit serves as a buck-boost conversion module. Furthermore, according to the requirements of the subsequent mouse system, a target voltage (Target Voltage) can be set at VRECT. In order to improve the conversion efficiency, this voltage value is set to different values ​​according to different output currents; the feedback loop can first collect the VRECT voltage and subtract it from the set target voltage to generate an error signal; the error signal will be transmitted to the MCU (Micro Controller Unit) of the transmitter through a prescribed communication method, and the MCU will determine whether the receiving end wants the transmitter to increase or reduce energy to meet the target voltage; thus, the MCU can control the output energy of the transmitter by controlling the input voltage of the power supply, the switching frequency of the power full bridge, and the input duty cycle of the power full bridge to accurately meet the charging requirements of the mouse; at the same time, in order to facilitate communication, two sets of grounding modules, switch W1, capacitor C4, and switch W2, capacitor C5, are added between the second capacitor C2 and the rectifier module to carry out the communication process during wireless charging.

[0060] Specifically, on the basis of realizing wireless charging, a charging interface can be further provided to facilitate the mouse to support different charging methods, further improve the user experience, and facilitate flexible use by users.

[0061] To solve the above technical problems, the utility model also provides a wireless charging device, including a transmitting coil T1 and a wirelessly rechargeable mouse as described above, wherein the input end of the transmitting coil T1 is connected to a power supply, and the output end is connected to the wirelessly rechargeable mouse.

[0062] It is not difficult to understand that the present application does not make any special restrictions on the specific types and implementation methods of the transmitting coil T1 and the power supply, and they can be selected and adjusted according to the needs of actual applications.

[0065] Specifically, the power full bridge, i.e., the full-bridge converter, may include a first power switch Q1, a second power switch Q2, a third power switch Q3, a fourth power switch Q4, and a third capacitor C3. The specific types and implementation methods of the first power switch Q1, the second power switch Q2, the third power switch Q3, the fourth power switch Q4, and the third capacitor C3 are not particularly limited in this application. The output process of alternating current can be effectively realized by turning on and off the power switch. The control method of each power switch is not particularly limited in this application, and can be adopted as follows: Figure 3 The PWM (Pulse Width Modulation) wave control method shown in the figure is implemented, the entire circuit structure is simple and easy to implement, the components used are low in cost and small in size, which is conducive to the simple implementation of the entire mouse and the entire wireless charging device.

[0066] As an optional embodiment, the power supply is a computer device connected to the mouse, and the input end of the transmitting coil T1 is connected to the computer device.

The transmitting coil T1 at the transmitting end can be pasted on the computer by pasting, which is convenient for wireless charging transmission connection and charging of the magnetic wireless charging mouse. The present application does not make any special restrictions on the fixing method and specific fixing position between the transmitting coil T1 and the computer. In order to facilitate pasting, the transmitting coil T1 can be set inside a thin sheet-shaped bearing structure.
