[0022] The present invention will be further described in detail below in conjunction with the embodiments and with reference to the accompanying drawings.

[0023] A keyboard with a balance switch, referring to Figures 1 to 5 , keyboard body 1, the keyboard body 1 includes a base 2, an annular shell 3 is provided on the base 2, and a button part 4 is provided on the left and right sides of the annular shell 3; a keyboard PCBA board 5 and a light receiving element electrically connected to the keyboard PCBA board 5 are also provided in the base 2, and a light emitting element is provided on the inner side of the annular shell 3 corresponding to the light receiving element. A keyboard with a balance switch provided by the present invention uses the optical coupling technology of a magnetic balance ball 6 and an infrared pair of tubes to act as a power switch 22 of a wireless keyboard. When the user puts the magnetic balance ball below near the transmitting element, the power 22 is turned on; when the magnetic balance ball 6 is moved away, the power 22 is turned off, thereby replacing the power switch 22 of the traditional wireless keyboard, with a novel structure, convenient use and energy saving. Secondly, the keyboard body 1 is a split keyboard, adopts a side input design, conforms to the ergonomic self-adjustment design, is easy to adjust flexibly, allows the wrist to work in a natural and relaxed state, can relieve office fatigue, has strong stability and high practicality.

[0024] In one embodiment, reference Figure 2 and Figure 3 The keyboard PCBA board 5 is electrically connected to the key part 4, and the key part 4 is arranged on the inner and outer sides of the annular shell 3. The annular shell 3 is connected to the base 2, and the key part 4 is arranged on the left and right sides of the annular shell 3. Keys 16 are correspondingly arranged on the outer ring and the inner ring of the left and right sides of the annular shell. The key part 4 is connected to the keyboard controller of the computer and receives the control signal sent by it.

[0025] In one embodiment, reference Figure 2 and Figure 3 The light receiving element is arranged in the magnetic balance ball 6, and the magnetic balance ball 6 includes an upper sphere 7 and a lower sphere 9; a receiving hole is provided on the top of the upper sphere 7, and a first annular magnet and an infrared switch tube are provided in the lower sphere 9. An infrared switch tube PCBA board 10 is magnetically attracted under the first annular magnet, and the infrared switch tube PCBA board 10 is electrically connected to the keyboard PCBA board 5 through a wire 11. The switch part of the power supply 22 in the present invention uses an infrared pair tube, and adopts optical elements such as light-emitting elements and light-receiving elements for light sensing. The switch is controlled by judging the resistors of different resistance values ​​formed by the light sensing. When the user places the magnetic balance ball 6 below at the corresponding position of the transmitting hole, due to the magnetic force of the first annular magnet set in the magnetic balance beam ball and the pulling action of the wire 11 in the opposite direction, it is in a balanced state at this time. At the same time, the infrared switch tube receives the infrared light of the transmitting tube, which is equivalent to opening the light path between the infrared light-emitting tube and the infrared switch tube, so that the infrared switch tube has sufficient light, and the resistance value becomes smaller, which is equivalent to the path, that is, the function of turning on the power supply 22 is completed; when the user moves the position of the magnetic balance ball 6, the power supply 22 is turned off.

[0026] In one embodiment, reference Figure 2 and Figure 3 The inner side of the top of the annular shell 3 is provided with an emitting hole at a position corresponding to the receiving hole at the top of the magnetic balancing ball 6, and the light emitting element is arranged in the emitting hole. The switch part of the power supply 22 in the present invention uses an infrared pair tube, and uses light elements such as a light emitting element and a light receiving element for light sensing. The switch is controlled by judging the resistors of different resistance values ​​formed by the light sensing. When the user places the magnetic balancing ball 6 below at the corresponding position of the emitting hole, light sensing is formed, thereby turning on the power supply 22 of the keyboard body 1.

[0027] In one embodiment, reference Figure 2 and Figure 3 The light emitting element includes a second annular magnet 12, a transmitting tube PCBA board 13 and an infrared transmitting tube, and the infrared transmitting tube is arranged in the transmitting hole. The light emitting element and the light receiving element can perform light sensing. In this embodiment, the light emitting element is an infrared light emitting diode, and the light receiving element is a phototransistor or a photoelectric integrated circuit.

[0028] In one embodiment, reference Figure 2 and Figure 3 The keyboard body 1 includes a front cover 14 and a rear cover 15 that cover each other. The outer key pressure sensor 17, the inner key pressure sensor 18, the inner glass key 20 and the outer glass key 21 are all installed at the covering position of the front cover 14 and the rear cover 15.

[0029] In one embodiment, reference Figure 2 and Figure 3 The button part 4 includes a button, an outer button pressure sensor 17, an inner button pressure sensor 18 and a buzzer 19. The button part 4 is arranged on the long sides of the annular housing 3, and is controlled by the thumb and the other four fingers respectively, that is, a thin film pressure sensor is used. When the user presses the corresponding button, the pressure directly acts on the thin film of the outer button pressure sensor 17 or the inner button pressure sensor 18 through the glass, so that the capacitance of the corresponding position of the button changes. When the keyboard controller detects the change of the capacitance value, it will automatically convert and output a standard signal corresponding to the pressure, so that the keyboard gives a corresponding code and notifies the buzzer 19 to feedback the "beep" sound, thereby realizing the key function.

[0030] In one embodiment, reference Figure 2 and Figure 3 The button is a glass button, and the glass button includes an inner glass button 20 and an outer glass button 21. The button adopts a transparent glass raised touch design to avoid accidental touch by the user during use.

[0031] refer to Figure 2 and Figure 3 A power source 22 is provided in the base 2, and the power source 22 is a battery power source 22 or a USB interface charging power source 22. In the present embodiment, the power source 22 is a battery, and a battery cover 24 is covered under the battery.

[0032] In one embodiment, reference Figure 2 and Figure 3 The wire 11 is provided with a wire tube 23 outside, and the length of the wire 11 is greater than the length of the wire tube 23. The magnetic balance ball 6 is connected to the wire 11. When the user turns off the power 22, the magnetic balance ball 6 is moved away to cut off the light source. Then, the length of the wire 11 is greater than the length of the wire tube 23. The wire tube 23 can protect the wire 11 and avoid external damage, and can also assist the connection between the light-emitting element and the light-receiving element.

[0033] The above is an explanation of the invention of a keyboard with a balance switch to help understand the present invention, but the implementation mode of the present invention is not limited to the above-mentioned embodiments. Any changes, modifications, substitutions, combinations, and simplifications made without departing from the principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
