Detailed Description
The wireless charging mouse provided by the embodiment of the invention can be used for normally maintaining the operation of the wireless charging mouse when the wireless charging mouse is moved or not moved by dynamically adjusting the charging electric energy and the operation electric energy of the wireless charging mouse. The operation electric energy is used for providing electric energy used when the wireless charging mouse works, and the charging electric energy is used for providing electric energy used by a charging battery. Specifically, the electric energy consumed by the wireless charging mouse during moving is larger than the electric energy consumed by the wireless charging mouse during non-moving, so that the wireless charging mouse can selectively increase the operation electric energy required by work and reduce the charging electric energy during moving. In another aspect, the wireless charging mouse of the present invention can also selectively increase the charging power and reduce the operation power required for operation when the mouse is not moved. As will be described in more detail below.
Referring to fig. 1, fig. 1 is a circuit block diagram of a wireless charging mouse according to an embodiment of the invention. The wireless charging mouse 1 comprises a wireless power receiving circuit 105, a displacement detecting circuit 110, a wireless transmitting circuit 115, a charging circuit 120, a control circuit 125, a power switching circuit 130 and a charging battery 135. For the convenience of the following description, the operation circuit 140 includes, for example, the displacement detection circuit 110, the wireless transmission circuit 115, and the control circuit 125. The control circuit 125 is electrically connected to the wireless power receiving circuit 105, the displacement detecting circuit 110, the wireless transmitting circuit 115 and the power switching circuit 130, respectively. In addition, the operation circuit 140 can receive the operation power provided by the power switching circuit 130 or the battery power provided by the rechargeable battery 135, and can be used as the power required by the internal circuit of the operation circuit 140. In addition, the operation circuit 140 may further include various types of input circuits such as a button circuit, a wheel circuit, or a touch circuit, etc. to provide various different operation input requirements for the wireless charging mouse 1, which is not limited herein to the implementation of the operation circuit 140.
The wireless power receiving circuit 105 may wirelessly receive electromagnetic energy supplied from the charging pad and use it as charging power or operation power for the wireless charging mouse 1. In detail, the wireless power receiving circuit 105 may be electromagnetically coupled to the charging pad, for example, when the resonant frequency of the magnetic coil of the wireless power receiving circuit 105 is the same as the resonant frequency of the magnetic coil of the wireless transmitting circuit of the charging pad, the wireless charging mouse 1 may wirelessly receive the electromagnetic energy transmitted by the charging pad. In one embodiment, the wireless power receiving circuit 105 may further include an electromagnetic conversion circuit to convert electromagnetic energy into electrical energy.
The wireless power receiving circuit 105 transmits the power to the power switching circuit 130, and the power switching circuit 130 can dynamically allocate the power to the operating power and the charging power according to the power switching signal. In detail, the power switching circuit 130 may adjust the power ratio of the operating power and the charging power. For example, the power switching circuit 130 may control the distribution of a part or all of the output power of the wireless power receiving circuit 105 into the operation power for the operation circuit 140 to work; alternatively, the power switching circuit 130 may distribute a part or all of the power output by the wireless power receiving circuit 105 to the charging power for the charging circuit 120, the charging circuit 120 may transmit the charging power to the rechargeable battery 135 for storing power, and the rechargeable battery 135 may transmit the stored battery power to the operation circuit 140.
The displacement detection circuit 110 is used to detect the movement of the wireless charging mouse 1, the displacement detection circuit 110 is implemented by an optical detection method, for example, to determine the movement amount and the movement direction of the wireless charging mouse 1, but the present invention is not limited to the detection method, a light source unit (not shown) of the displacement detection circuit 110 may irradiate a plane with laser (L aser) or Infrared (Infrared), a receiving unit (not shown) of the displacement detection circuit 110 may receive the laser or Infrared reflected by the plane, and the movement amount and the movement direction of the wireless charging mouse 1 are calculated according to a difference value between the incident light and the reflected light.
The control circuit 125 relatively generates a displacement detection signal according to the detection result of the displacement detection circuit 110. The control circuit 125 can transmit the displacement detection signal to the wireless transmitting circuit 115, and output the displacement detection signal to an electronic device (not shown) through the wireless communication function of the wireless transmitting circuit 115. The electronic device is, for example, a desktop computer or a notebook computer, wherein the wireless communication function of the wireless transmitting circuit 115 can be Bluetooth (Bluetooth) or Radio Frequency (RF). The control circuit 125 is a related circuit having an arithmetic processing capability, such as a processor or a controller, but the invention is not limited thereto.
Furthermore, the control circuit 125 transmits the generated power switching signal to the power switching circuit 130 when the wireless charging mouse 1 is moved, and the power switching circuit 130 can selectively boost the operation power and reduce the charging power according to the power switching signal. For example, when the wireless charging mouse 1 is moved, if the power required by the operation circuit 140 to maintain normal operation or full-speed operation exceeds the battery power that can be supplied by the charging battery 135, the operation power can be increased and the charging power can be decreased, so that most or all of the power required by the operation circuit 140 to operate can be provided by the operation power output by the power switching circuit 130. Conversely, the power switching signal generated by the control circuit 125 when the wireless charging mouse 1 is not moved enables the power switching circuit 130 to selectively reduce the operating power and increase the charging power. For example, when the wireless charging mouse 1 is not moved, if the power required by the operation circuit 140 can be completely supplied by the rechargeable battery 135, the power switching circuit 130 can reduce the operation power and increase the charging power, so that the power required by the operation circuit 140 can be mostly or completely supplied by the battery power output by the rechargeable battery 135, and the charging speed of the rechargeable battery 135 can be accelerated at the same time.
In addition, in an embodiment, the power switching circuit 130 may implement the above-mentioned power supply adjustment related to the operating power and the charging power by a buck-boost converter, for example. For example, the up/down converter can control the voltage level of the output voltage Vo of the operating power or the charging voltage Vc of the charging power to be raised, and the up/down converter can also control the voltage level of the output voltage Vo of the operating power or the charging voltage Vc of the charging power to be lowered. However, it should be noted that the present invention is not limited to the embodiment of the power converter circuit 130.
For the embodiment of the power switching circuit 130 adjusting the power ratio of the operating power and the charging power, refer to the following example. When the wireless charging mouse 1 is still and does not move, the power switching circuit 130 is enabled by the power switching signal generated by the control circuit 125 to use 80% of the power output by the wireless power receiving circuit 105 as the charging power and use the remaining 20% as the operating power. On the contrary, when the wireless charging mouse 1 is in motion, the control circuit 125 generates the power switching signal, so that the power switching circuit 130 can use 90% of the power output by the wireless power receiving circuit 105 as the operating power and use the remaining 10% as the charging power. The proportion of the electric energy is designed differently by those skilled in the art according to the habit of the user operating the mouse, and the invention is not limited thereto.
In addition, in an embodiment, when the wireless charging mouse 1 moves, the control circuit 125 may detect whether the power of the rechargeable battery 135 is higher than a predetermined value before outputting the power switching signal, for example, 90% of the power of the rechargeable battery 135 required for the full-speed operation of the operation circuit 140. Therefore, when the control circuit 125 determines that the power of the rechargeable battery 135 is higher than the predetermined value, the control circuit 125 may not output the power switching signal to the power switching circuit 130.
Referring to fig. 2, fig. 2 is a circuit block diagram of a wireless charging mouse device according to an embodiment of the invention. Fig. 2 adds a charging plate 2 to fig. 1. The charging pad 2 is used to transmit electromagnetic energy to the wireless charging mouse 1 in a wireless manner. The charging board 2 includes a power supply circuit 205 and a plurality of wireless power transmitting circuits 210, and each wireless power transmitting circuit 210 is electrically connected to the power supply circuit 205. Each wireless power transmitting circuit 210 further includes a wireless power transmitting module and a magnetic coil. The power supply circuit 205 is connected to the power transmitted by the external power source through a connection terminal, for example, a Universal Serial Bus (USB) connector. How to electromagnetically couple the wireless power transmitting circuit and the wireless power receiving circuit is well known in the art, and will not be described in detail herein.
In addition, in an embodiment, the control circuit 125 can determine whether the wireless charging mouse 1 moves when the amount of the optical image data detected by the displacement detection circuit 110 changes. For example, the displacement detection circuit 110 can determine whether the wireless charging mouse 1 moves according to the amount of optical image data generated by the light source unit and the receiving unit through the difference between the incident light and the reflected light. In another embodiment, the control circuit 125 may also determine whether the wireless charging mouse 1 moves according to the change of the electromagnetic energy received by the wireless power receiving circuit 105, which will be described in detail later.
Therefore, the control circuit 125 can determine whether the wireless charging mouse 1 moves through the displacement detection circuit 110 to generate a power switching signal and transmit the power switching signal to the power switching circuit 130. For example, when the control circuit 125 determines that the wireless charging mouse 1 is determined to be moved by the change in the output optical image data amount of the displacement detection circuit 110, the power switching circuit 130 increases the operation power and decreases the charging power according to the power switching signal generated by the control circuit 125, which indicates that the power required by the operation circuit 140 is greater than the power required by the charging circuit 120 when the wireless charging mouse 1 is moved, and the charging voltage V output by the power switching circuit at this timeCMay for example be smaller than the output voltage VO. On the contrary, for example, when the control circuit 125 determines that the amount of the optical image data outputted from the displacement detection circuit 110 is not changed, the control circuit 125 may determine that the wireless charging mouse 1 is not moved, so that the power switching signal received by the power switching circuit 130 is to decrease the operating power and increase the charging power, which means that the power required by the operating circuit 140 is less than the power required by the charging circuit 120 when the wireless charging mouse 1 is not moved, and the charging voltage V outputted by the power switching circuit 130 is at this timeCE.g. greater than the output voltage VO。
Referring to fig. 2 and fig. 3, fig. 3 is an appearance schematic diagram of a wireless charging mouse device according to an embodiment of the invention. The charging board 2 shown in fig. 3 has a plurality of wireless power transmitting circuits 210, and the wireless charging mouse 1 can be wirelessly charged when being placed on the charging board 2 and when not being moved. For example, when the user clicks only the left button, the right button or the sliding wheel of the wireless charging mouse 1 and does not move the wireless charging mouse 1, the control circuit 125 may determine that the wireless charging mouse 1 is not moved through the displacement detection circuit 110, and the control circuit 125 generates the power switching signal according to the determination result to enable the power switching circuit 130 to increase the charging power and decrease the operating power, that is, most or all of the electromagnetic energy wirelessly received by the wireless charging mouse through the charging pad may be used as the charging power. On the contrary, when the user moves the wireless charging mouse 1 on the charging pad 2, the control circuit 125 can determine that the wireless charging mouse 1 moves through the displacement detection circuit 110, and the control circuit 125 generates the power switching signal according to the determination result to enable the power switching circuit 130 to increase the operation power and decrease the charging power, that is, most or all of the electromagnetic energy wirelessly received by the wireless charging mouse 1 through the charging pad 2 can be used as the operation power. In addition, the number and the positions of the wireless power transmitting circuits shown in the charging pad 2 of fig. 3 are only for illustration and are not intended to limit the present invention.
Referring to fig. 2 and fig. 4, fig. 4 is an appearance schematic diagram of a wireless charging mouse device according to an embodiment of the invention. The charging plate 2a shown in fig. 4 is different from the charging plate 2 shown in fig. 3 in the arrangement of the wireless power transmitting circuit. In the case of the charging pad 2a shown in fig. 4, a plurality of wireless power transmitting circuits 210a and 210b are disposed in the charging pad 2a, and the wireless power transmitting circuits 210a and the wireless power transmitting circuits 210b are alternately disposed in a spaced arrangement. In addition, the wireless power transmitting circuit 210a is an output that can provide a larger electromagnetic energy to the wireless charging mouse 1 than the wireless power transmitting circuit 210 b. It should be noted that the wireless charging mouse 1 shown in fig. 4 is determined that the wireless charging mouse 1 is moved by the wireless power receiving circuit 105 receiving a change in the electromagnetic quantity provided by the charging pad 2a, and the wireless charging mouse 1 is determined that the wireless charging mouse 1 is not moved by the wireless power receiving circuit 105 receiving no change in the electromagnetic quantity provided by the charging pad 2 a. For example, when the position of one of the wireless power transmission circuits 210a of the wireless charging mouse 1 on the charging pad 2a is moved to the position of the other wireless power transmission circuit 210b, or the position of one of the wireless power transmission circuits 210b of the wireless charging mouse 1 on the charging pad 2a is moved to the position of the other wireless power transmission circuit 210 a. The control circuit 125 in the wireless charging mouse 1 knows that the received electromagnetic quantity changes through the wireless power receiving circuit 105, for example, when the electromagnetic energy received by the wireless charging mouse 1 changes from the first electromagnetic energy to the second electromagnetic energy, the control circuit 125 can determine that the wireless charging mouse 1 is moved accordingly. On the other hand, when the wireless charging mouse 1 is still at the position of one of the wireless power transmitting circuit 210a or the wireless power transmitting circuit 210b on the charging board 2a, the control circuit 125 in the wireless charging mouse 1 knows that the received electromagnetic quantity is not changed through the wireless power receiving circuit 105, and accordingly, it is determined that the wireless charging mouse 1 is not moved.
In the configuration of fig. 4, when the wireless charging mouse 1 determines whether there is movement according to the received electromagnetic quantity, the following adjustment manner of the power ratio of the operation power and the charging power is the same as the foregoing embodiment, and is not described in detail herein. However, in an embodiment, when the control circuit 125 in the wireless charging mouse 1 knows that the received electromagnetic quantity changes through the wireless power receiving circuit 105, the control circuit may further determine whether the electromagnetic quantity change is completed within a predetermined time, and accordingly determine whether to adjust a report rate (report rate) of the wireless charging mouse. For example, when the time for the electromagnetic energy received by the wireless charging mouse 1 to be changed from the first electromagnetic energy to the second electromagnetic energy is completed within a predetermined time, which represents that the wireless charging mouse is rapidly moved, the control circuit 125 may adjust the rate of return for using the wireless charging mouse 1 from the first rate of return to the second rate of return, wherein the second rate of return is higher than the first rate of return, so that various input operations of the wireless charging mouse 1 can be rapidly responded.
Referring to fig. 5, fig. 5 is a flowchart illustrating a charging method of a wireless charging mouse according to an embodiment of the present invention, and the following description is referred to with reference to fig. 2. In step S505, electromagnetic energy transmitted by the plurality of wireless power transmitting circuits of the charging pad is received by the wireless charging mouse. When one of the wireless power transmitting circuits in the charging panel is electromagnetically coupled with the wireless power receiving circuit of the wireless charging mouse, the wireless power receiving circuit of the wireless charging mouse can receive electromagnetic energy transmitted by one of the wireless power transmitting circuits in the charging panel.
In step S510, it is determined whether the wireless charging mouse has moved. The manner of detecting the movement of the wireless charging mouse can be determined according to the change of electromagnetic energy or the change of optical image data amount, and the detailed determination manner is mentioned in the foregoing embodiments and is not described herein. If the determination in step S510 is yes, the process proceeds to step S515. If the determination in step S510 is no, the process proceeds to step S520.
In step S515, the power switching signal generated by the control circuit, for example, enables the power switching circuit to boost the operating power and reduce the charging power, i.e., the operating circuit of the wireless charging mouse needs more power when moving, so that the wireless charging mouse can be ensured to operate normally or at full speed by boosting the operating power directly supplied to the operating circuit.
In step S520, the power switching signal generated by the control circuit, for example, enables the power switching circuit to reduce the operation power and increase the charging power, i.e., the operation circuit of the wireless charging mouse does not consume too much power when not moving, so that the charging power is increased to speed up the charging of the rechargeable battery in addition to ensuring the normal operation of the wireless charging mouse.
In this embodiment, the power switching circuit adjusts the electric energy ratio of the operation electric energy distributed by the electromagnetic energy to the charging electric energy used by the charging circuit of the wireless charging mouse for the wireless charging mouse to work according to the power switching signal, and determines whether the wireless charging mouse moves, and appropriately adjusts the electric energy ratio of the operation electric energy to the charging electric energy, so that the wireless charging mouse can maintain normal operation when the wireless charging mouse moves or does not move.
Referring to fig. 6, fig. 6 is a flowchart illustrating a charging method of a wireless charging mouse according to an embodiment of the present invention, and the following description is referred to with reference to fig. 2. Fig. 6 is a flowchart of the steps for determining whether the power of the rechargeable battery is greater than a predetermined value, which is added to fig. 5.
In step S605, electromagnetic energy transmitted by the plurality of wireless power transmitting circuits of the charging pad is received by the wireless charging mouse. The wireless power receiving circuit of the wireless charging mouse can receive electromagnetic energy transmitted by a wireless power transmitting circuit in the charging panel.
In step S607, the control circuit determines whether the power of the rechargeable battery is greater than a predetermined value. If the determination in step S607 is yes, the process proceeds to step S609. In step S609, the wireless power receiving circuit outputs only the electric energy to the charging circuit. If the determination in step S607 is no, the process proceeds to step S610.
In step S610, it is determined whether the wireless charging mouse has moved. The manner of detecting the movement of the wireless charging mouse can be changed according to the change of electromagnetic energy or the change of optical image data. If the determination in step S610 is yes, the process proceeds to step 615. If the determination in step S610 is no, the process proceeds to step S620.
In step S615, the control circuit generates the power switching signal to, for example, enable the power switching circuit to boost the operating power and reduce the charging power.
In step S620, the power switching signal generated by the control circuit is, for example, to enable the power switching circuit to lower the operating power and raise the charging power.
In this embodiment, when the control circuit detects that the power of the rechargeable battery is higher than a preset value, the wireless power receiving circuit outputs the power to the operating circuit, in other words, the control circuit does not generate the power switching signal to distribute the power; on the contrary, when the control circuit detects that the electric power of the rechargeable battery is smaller than a preset value, the control circuit relatively generates a power switching signal according to whether the wireless charging mouse moves so as to distribute the electric energy to the operation electric energy required by the operation circuit or distribute the electric energy to the charging electric energy required by the charging circuit.
In summary, the present invention provides a wireless charging mouse with power distribution function, wherein a power switching circuit adjusts a ratio of a charging power output by a wireless power receiving circuit and supplied to a charging battery to be used and an operating power supplied to an operating circuit according to a received power switching signal by determining whether the wireless charging mouse moves to generate a corresponding power switching signal, so as to improve an effective power distribution function, thereby avoiding a trouble that the wireless charging mouse runs out of the charging battery due to high-speed movement and ensuring that the wireless charging mouse can normally operate in any state.
The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention. Any variations and equivalent alterations made by those skilled in the art without departing from the spirit and scope of the present invention are still within the scope of the present invention.
