Embodiment

Please refer to Fig. 2, Fig. 2 is Wireless Computer Circumference Device of the present invention and computer schematic diagram.Wireless Computer Circumference Device 40 passes through the wireless mode line with computer 50, wherein Wireless Computer Circumference Device 40 comprises a microprocessor 41, a power storage unit 42, a voltage detection unit 43, one first wireless transmit/receive units 44 and an electric energy converting unit 45, and computer 50 comprises one second wireless transmit/receive units 51 and a display unit 52.

Microprocessor 41 is electrically connected on voltage detection unit 43, wireless transmit/receive units 44 and electric energy converting unit 45, power storage unit 42 is electrically connected on electric energy converting unit 45, wherein voltage detection unit 43 is in order to detect the voltage of power storage unit 42, and electric energy converting unit 45 is in order to specific wireless signal, for example a charging signals is converted to electric energy.

In this preferred embodiment, Wireless Computer Circumference Device 40 is a radio input device, particularly a wireless mouse.Power storage unit 42 is a rechargeable battery, and is built in the computer 50 in the second wireless transmit/receive units 51, in order to receive and to transmit wireless signal.In addition, the first wireless transmit/receive units 44 and the second wireless transmit/receive units 51 all are applicable to the direct-connected transmission communication pattern of Wi-Fi (Wi-Fi Direct).More than explanation is only for required for example, not as limit.

Please refer to Fig. 3, Fig. 3 is the flow chart of the wireless charging method of Wireless Computer Circumference Device of the present invention.At first, shown in step S1, microprocessor 41 judges that according to the testing result of voltage detection unit 43 whether the voltage of Wireless Computer Circumference Device 40 is less than threshold value.In this preferred embodiment, threshold value is preset as 2 volts.

If voltage more than or equal to threshold value, even the storage electric power that means in the power storage unit 42 is enough, there is no the needs that carry out charging procedure, so repeating step S1.If but voltage is less than threshold value, then therefore the existing not enough problem of the storage electric power in the power storage unit 42 automatically starts charging procedure, and enters step S2.

Shown in step S2, the first wireless transmit/receive units 44 of Wireless Computer Circumference Device 40 transmits a notification signal to the second wireless transmit/receive units 51 of computer 50.After the second wireless transmit/receive units 51 receives notification signal, computer 50 begins to search near can launch the Wi-Fi radio wave current location a access point, and therefrom select object access point via the automatic or manual mode, in order to the power source supply end as wireless charging.In this preferred embodiment, access point is near the wireless network base stations computer 50 itself, the computer 50, or radio network router.

The mode of above-mentioned select target access point is with existing mode and the indifference of radio base station to carry out radio connecting of selecting.For instance, computer 50 can be selected the object access point automatically according to the power of radio wave, or as shown in Figure 4, Fig. 4 is inventory schematic diagram of the present invention, display unit 52 by computer 50 is the access point AP1 that row search with inventory 53, AP2, AP3 therefrom selects the object access point via the user.In addition, if the object access point has protectiveness, the user can be through identification code or the password of computer 50 input object access points.

After the selection of object access point was finished, the second wireless transmit/receive units 51 of computer 50 transmitted a response notification signal to the first wireless transmit/receive units 44 of Wireless Computer Circumference Device 40, and wherein the response notification signal comprises a link information of object access point.If object access point does not have protectiveness, then link information comprises the identification code of object access point, if the object access point has protectiveness, then link information comprises identification code and the password of object access point.In this preferred embodiment, identification code is the service setting identification code (Service Set Identifier, SSID) of object access point, but not as limit.

Then, shown in step S3, the first wireless transmit/receive units 44 of Wireless Computer Circumference Device 40 receives the response notification signals, and according to the link information of response notification signal, carries out line with the object access point.

After Wireless Computer Circumference Device 40 and object access point are set up line, the first wireless transmit/receive units 44 of Wireless Computer Circumference Device 40 will transmit a charging request signal to the object access point, shown in step S4, and after the object access point receives the charging request signal, then begin Wireless Computer Circumference Device 40 is transmitted charging signals.

Then, shown in step S5, the first wireless transmit/receive units 44 of Wireless Computer Circumference Device 40 receives a package, and enters step S6.

Shown in step S6, the microprocessor 41 of Wireless Computer Circumference Device 40 judges whether the package that receives is charging signals, if, then enter step S7, shown in step S7, by electric energy converting unit 45 package is converted to an electric energy and is stored in power storage unit 42, be reached for the purpose that Wireless Computer Circumference Device 40 carries out wireless charging.

But often has multiple additional functionality based on present Wireless Computer Circumference Device 40, need to produce corresponding action according to the instruction from computer 50, such as, in response to game content vibrations etc. luminous in response to letter, just it is not ignored if do not analyze the package of non-charging signals, will cause Wireless Computer Circumference Device 40 can't produce corresponding action.Therefore, non-for charging signals if microprocessor 41 is judged the package that receives in present embodiment, then enter step S8.

Shown in step S8, whether the microprocessor 41 of Wireless Computer Circumference Device 40 judges package from computer 50, if then shown in step S9, analyze a content of package, and produce an action command, such as luminous or vibrations etc. according to the content of package.If not, then shown in step S10, need not produce any action.

According to the explanation of above preferred embodiment as can be known, the wireless charging method of Wireless Computer Circumference Device of the present invention, by transmitting the access point of radio wave near the computer search, behind the selected target access point, link information with object access point is sent to Wireless Computer Circumference Device again, make Wireless Computer Circumference Device and object access point line, and obtained charging signals to carry out wireless charging.So, not only effectively utilize the Radio Resource in the environment, and use the storage type power supply and inconvenient providing in the situation of excrescent electric power at computer, Wireless Computer Circumference Device still can select other access point as power source supply end, thereby increases feasibility and the convenience of wireless charging.

The above is preferred embodiment of the present invention only, is not to limit claim of the present invention, and therefore all other do not break away from the equivalence change of finishing under the disclosed spirit or modify, and all should be contained in the claim of this case.
