Description

Technical Field

[0001] This invention relates to the field of mouse technology, and more particularly to a microwave wireless charging mouse. Background Technology

[0002] With the widespread adoption of wireless office equipment, wireless mice have become the mainstream choice for computer users due to their freedom from cables and ease of use. Currently, wireless mice are mainly powered by disposable batteries and wired charging or electromagnetic induction wireless charging. Disposable batteries require frequent battery replacements, increasing user costs and potentially causing environmental pollution. Wired charging requires a data cable connection to a power source or computer interface, violating the core requirement of "wireless use," and the mouse cannot be operated while charging. While electromagnetic induction wireless charging achieves contactless charging, it suffers from drawbacks such as extremely short charging distance (usually no more than 10mm), the need to adhere to a charging base, and limited charging positions. Users still need to frequently place the mouse in a specific charging area, significantly reducing its convenience.

[0003] Microwave wireless transmission technology, as a far-field wireless energy transmission method, can achieve wireless energy transfer within a range of several meters. It has advantages such as long transmission distance, no contact required, and flexible positioning, and has been initially applied in some electronic devices. In existing technologies, microwave wireless charging is mostly used in large equipment or long-distance power supply scenarios. There is no microwave wireless charging solution specifically for small, precision input devices such as mice. Due to the small size and limited internal space of mice, it is difficult to integrate large microwave receiving and energy conversion modules. Furthermore, traditional microwave transmission suffers from problems such as high energy loss, low charging efficiency, and electromagnetic radiation that does not meet human safety standards, making it unsuitable for the low power consumption and miniaturization requirements of mice.

[0004] In addition, existing wireless mice lack intelligent monitoring and adjustment mechanisms for charging status, which can easily lead to problems such as overcharging, shortened battery life, and energy waste during charging. Summary of the Invention

This solves the technical problem of integrating microwave charging modules into small mice.

[0025] Through two-way communication between the receiver and transmitter, real-time monitoring of charging status, power information, and mouse position is achieved. The transmitter can dynamically adjust the microwave transmission power and direction according to the mouse position, and the receiver can control the start and stop of charging according to the battery power to avoid energy waste. At the same time, users can understand the charging progress in real time, improving the user experience.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Example 1

[0036] Reference Figures 1-6 A microwave wireless charging mouse includes a mouse body 1, a microwave wireless charging transmitter, and a microwave wireless charging receiver. The mouse body 1 includes a shell, a main control module, a power supply module, a mouse operation module, and a communication module. The microwave wireless charging transmitter is connected to an external power source to generate and transmit microwave energy signals. The microwave wireless charging receiver receives microwave energy signals and converts them into stable DC power to charge the power supply module. The shell has an internal mounting cavity where the main control module, power supply module, and microwave wireless charging receiver are fixedly installed. The mouse operation module, communication module, and microwave wireless charging receiver are all electrically connected to the main control module, and the power supply module provides operating power to all modules of the mouse body 1. The microwave wireless charging receiver is integrated inside the mouse body and is electrically connected to the power supply module inside the mouse body 1.

[0037] The outer side of the mouse body 1 is provided with a connecting pad 3, the outer side of the connecting pad 3 is provided with multiple raised massage blocks 4, the inner side of the connecting pad 3 is provided with multiple slots 5, the outer side of the mouse body 1 is fixedly installed with multiple blocks 6, the blocks 6 are engaged with the corresponding slots 5, the top of the blocks 6 is provided with an iron plate 7, and the top inner wall of the slots 5 is provided with a magnet 8, which is used to attract the iron plate 7.

[0038] The microwave wireless charging transmitter includes a transmitter main control unit, a microwave generation module, a transmitting antenna array, a transmitter communication module, and a transmitter power supply module;

[0039] The microwave wireless charging receiver includes a receiving antenna, a rectification and voltage regulation module, a receiver main control unit, and a receiver communication module.

[0040] In this embodiment, the transmitter power module is connected to the external mains power to convert the mains power into a stable DC voltage to power each module of the transmitter; the transmitter main control unit is electrically connected to the microwave generation module, the transmitting antenna array, and the transmitter communication module, respectively, to control the microwave generation module to generate microwave energy signals of a preset frequency, and to control the transmitting antenna array to directionally transmit the microwave energy signals to the microwave wireless charging receiver.

[0041] In this embodiment, the transmitter communication module is used to communicate bidirectionally with the microwave wireless charging receiver to transmit charging status and location information data; the microwave generation module uses a magnetron as a microwave source to generate microwave energy signals with a frequency of 2.45GHz or 5.8GHz; the transmitting antenna array is composed of microstrip patch antennas, and through the control of the transmitter main control unit, it realizes the directional focusing transmission of microwave energy, reduces energy loss, and increases the transmission distance.

[0042] In this embodiment, the receiving antenna is a miniaturized rectifier antenna integrated into the inner wall of the mouse body shell, used to receive the microwave energy signal emitted by the microwave wireless charging transmitter; the rectifier and voltage regulator module is electrically connected to the receiving antenna, used to convert the received microwave AC signal into a DC signal, perform voltage regulation, and output a stable charging voltage to the power supply module.

[0043] In this embodiment, the receiver main control unit is electrically connected to the rectifier and voltage regulator module, the receiver communication module, and the main control module, respectively. It monitors the output voltage and current of the rectifier and voltage regulator module, as well as the charging status of the power supply module, and feeds back the relevant data to the microwave wireless charging transmitter via the receiver communication module. The receiver communication module and the transmitter communication module are connected wirelessly to achieve bidirectional data interaction. The rectifier and voltage regulator module includes an RF synthesis unit, a rectification unit, and a voltage regulation unit. The RF synthesis unit uses a power divider to group and synthesize the microwave energy received by the receiving antenna, making the input power more uniform and providing good conditions for subsequent rectification. The rectification unit uses a Schottky diode rectifier bridge to convert the synthesized microwave AC signal into a DC signal. The voltage regulation unit uses an AMS1117 voltage regulator chip to regulate the DC signal to 3.7V, outputting a stable charging voltage to the charging battery of the power supply module.

[0044] In this embodiment, the rectification and voltage regulation module adopts a hybrid power synthesis optimization method, which groups the microwave energy received by the receiving antenna into radio frequency synthesis before performing rectification and voltage regulation.

[0045] In this embodiment, the power supply module includes a rechargeable battery, a battery protection module, and a power detection module. The rechargeable battery is a small lithium battery. The battery protection module is electrically connected to the rechargeable battery to prevent overcharging, over-discharging, overcurrent, and short circuits, thereby extending the battery's lifespan. The power detection module is electrically connected to the rechargeable battery and the main control module to detect the remaining power of the rechargeable battery in real time and feed the power information back to the main control module. The main control module can then feed the power information back to the user via an indicator light or a communication module.

[0046] In this embodiment, the main control module uses a low-power microcontroller to control the signal acquisition and processing of the mouse operation module, the signal transmission of the communication module, the working status of the microwave wireless charging receiver, and the power management of the power supply module.

[0047] In this embodiment, the mouse operation module includes a left button, a right button, a scroll wheel 2, and a photoelectric sensor, which are used to collect user operation signals and transmit them to the main control module. After processing the operation signals, the main control module sends them to the computer terminal through the communication module. The communication module adopts a Bluetooth or 2.4GHz wireless communication module to realize wireless data interaction between the mouse and the computer terminal, and can also transmit charging status and power information data.

[0048] In this embodiment, the microwave wireless charging transmitter is also equipped with a position detection module, which is electrically connected to the transmitter main control unit. This module is used to detect the position information of the mouse body and feed the position information back to the transmitter main control unit. The transmitter main control unit dynamically adjusts the microwave transmission direction and power of the transmitting antenna array according to the position of the mouse body to ensure that the microwave energy can be accurately transmitted to the microwave wireless charging receiver.

[0049] The work process is as follows:

[0050] When the microwave wireless charging transmitter is activated, the transmitter power module converts the external AC power into a stable DC voltage to power all modules of the transmitter. The transmitter main control unit controls the position detection module to start, begins to detect the real-time position of the mouse, and transmits low-power detection microwaves through the transmitting antenna array.

[0051] When the mouse is in working condition, after the receiving antenna of the microwave wireless charging receiver receives the probe microwave, the receiver main control unit feeds back the mouse position information and battery power information to the transmitter through the receiver communication module. If the battery power is lower than a preset threshold (such as 20%), the transmitter main control unit controls the microwave generation module to start, generating a 2.45GHz microwave energy signal. At the same time, according to the mouse position information, it controls the transmitting antenna array to directionally focus and transmit microwave energy.

[0052] After receiving the microwave energy signal, the receiving antenna transmits it to the rectification and voltage regulation module. The radio frequency synthesis unit performs radio frequency synthesis on the microwave energy to make the power distribution uniform. Then the rectification unit converts the microwave AC signal into a DC signal, and the voltage regulation unit performs voltage regulation on the DC signal to output a stable 3.7V voltage to charge the rechargeable battery. The battery protection module monitors the charging process in real time to prevent overcharging, overcurrent and other problems.

[0053] During charging, the power detection module monitors the remaining power of the charging battery in real time, and the receiving end main control unit feeds back data such as charging current and power changes to the transmitting end. The transmitting end main control unit dynamically adjusts the microwave transmission power based on the feedback data. When the battery is fully charged (e.g., reaches 100%), it controls the microwave generation module to stop working and ends the charging process. If the mouse position moves, the position detection module updates the position data in real time, and the transmitting end main control unit adjusts the transmission direction of the transmitting antenna array to ensure charging stability.

[0054] When a user uses the mouse, the mouse operation module collects operation signals and transmits them to the main control module for processing. The main control module then sends the operation signals to the computer terminal via the communication module to enable normal mouse operation. At the same time, the main control module feeds back battery power information to the user via the communication module, allowing the user to monitor the charging progress.

[0055] Example 2

[0056] The difference between this embodiment and Embodiment 1 is that the mouse body 1 is equipped with an intelligent wake-up module, which uses infrared sensing technology to wake up the mouse when the palm is near and to put it into sleep mode when there is no operation for a long time, thereby reducing power consumption.

[0057] The rest is the same as in Example 1.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
