[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a kind of wireless keyboard, and more particularly, to a kind of wireless keyboard which provides a standby mode power supply of a wireless keyboard by using a kind of solar battery, thereby greatly extending the use time of the battery and enhancing its function.

[0002]

[Prior art]

 It is necessary to perform signal conversion operation and data transmission between the known traditional computer and each peripheral equipment through an appropriate transmission interface and interconnected by a signal cable. However, since the signal cable is located between each peripheral equipment and the computer, each peripheral equipment is affected by the conductor. For example, the range of movement of the mouse was limited, and the tablet and keyboard could not be placed outside the wire length range, resulting in operational inconvenience and problems.

[0003] Wireless computer peripherals are an effective solution, thereby freeing various peripherals from the limitations of connecting cables. However, wireless peripherals have one obvious disadvantage. That is, an extra and independent power source is required. For example, a wireless keyboard or tablet needs to provide working power with an internal DC battery. The power consumption of such wireless peripherals is not very large, but the power of DC batteries is finite and their service life is fixed. Must be replaced. In particular, even when these peripherals are not used for a while, the battery power continues to be consumed even when the peripheral equipment is not used for a while, so that the use time of the battery has been relatively shortened and energy resources have been wasted.

[0004] Therefore, it is necessary to effectively solve the problem of the power supply of the well-known wireless keyboard.

[0005]

[Problems to be solved by the invention]

【Example】

 As shown in FIGS. 1 and 2, the wireless keyboard 10 of the present invention includes a CPU 14, a transmitter 15, and a set of power supplies 16 inside a base sheet 11 provided with a key group 12 and a trackball 13. This is a wireless keyboard equipped with a wireless signal controller configured to transmit a keyboard operation signal to a computer.

As shown in FIG. 1, in the above-described wireless keyboard 10, the key group 12 includes general keys and special keys located on the surface of the base sheet 11, and the trackball 13 is provided on the surface of the base sheet 11. Is provided at one corner.

As shown in FIG. 2, in the above-described wireless signal control device of the wireless keyboard 10, the CPU 14 processes a keyboard signal, and the transmitter 15 communicates with the keyboard using IR transmission and / or RF transmission. Signals are transmitted between the computers, and the keyboard controls and operates the computers in a wireless manner.

As shown in FIG. 2, the power supply 16 supplies necessary power for the system and includes a charging and power supply controller 17, a set of dry batteries 18 or a set of secondary batteries 19, and A DC power supply provides working power for the CPU 14 and the transmitter 15 via the charging and power supply controller 17. The power supply 16 also includes a separate set of solar cells 20 which have a continuous and constant energy source by the light source.

As shown in FIG. 1, the light collector 21 of the solar cell 20 can be installed at an appropriate position on the surface of the base sheet 11, for example, above the key group 12.

The features of the operation when actually operating the present apparatus are as follows. 1. When the dry battery 18 or the secondary battery 19 of the power supply 16 is used as a working power source and a key of the key group 12 is pressed by an operator, an output signal thereof is sent to the CPU 14. 2. The CPU 14 processes the signals and sends the signals to the computer via the transmitter 15 in a wireless manner. 3. Since the wireless keyboard 10 is a kind of USB HID (Hurman Input Device) peripheral equipment, when a user does not use the keyboard for a while, the wireless keyboard 10 automatically enters a standby mode (suspend mode) to save power. At this time, the solar cell 20 slightly supplies the power required for the system wake-up function (Remote Wake Up). 4. After entering the standby mode, if the user presses the key again, the signal enters again to execute the instant wake-up function, and the dry cell 18 or the secondary cell 19 provides the working power of the CPU 14 and the transmitter 15. The signal is sent to the computer via the transmitter 15.

Since the power required for the wake-up function of the USB HID wireless keyboard 10 is extremely small, the solar battery 20 can sufficiently withstand use, and therefore the wireless keyboard is in a standby state, and the dry battery 18 or the secondary battery 19 It consumes less energy, prolongs battery life, and achieves a power-saving function.

[0015]

[Effect of the invention]

 Therefore, the present invention effectively solves the problem of power consumption of the wireless keyboard by providing the power required for the standby mode and the wake function of the wireless keyboard by the solar battery, and the structure of the device of the present invention is By combining a solar cell with a wireless signal controller, the wireless keyboard does not consume the power of a well-known battery in standby mode, greatly extending the battery usage time and increasing the service life. However, its improvement and inventive step are not in the well-known technology and therefore meet the requirements for utility model registration.
