Abstract

The utility model discloses a tumbler wireless keyboard which comprises a rotating shaft and a keyboard body. The rotating shaft is a C type cylindrical barrel body, and the keyboard body is embedded in the rotating shaft. A plurality of fan-shaped grooves are formed in the inner wall of one arc-shaped side of the rotating shaft in an axial direction, metal blocks are arranged inside the fan-shaped grooves respectively, a battery containing bin is arranged in the middle of one arc-shaped side of the rotating shaft in the axial direction, and a horizontal electronic control chip and a wireless bluetooth chip are arranged inside one opening side of the rotating shaft. Annular LED lamps are arranged at the two ends of the rotating shaft respectively. A plurality of buttons are arranged on the surface of the keyboard body. The tumbler wireless keyboard stands upright in a normal state, and when the keyboard needs to be used, the keyboard body is pressed down. The tumbler wireless keyboard can solve the problem that the power consumption of a wireless keyboard is severe, and can overcome the defect that the keyboard occupies space when not used. The structure is simple, and using is convenient.

Description

The tumbler Wireless Keyboard

Technical field

The utility model relates to a kind of Wireless Keyboard, especially a kind of keyboard that reaches energy savings and space purpose by the object of " tumbler " towards the low state variation principle of potential energy.

Background technology

Existing keyboard roughly is divided into two kinds: wired and wireless.

Wired keyboard adopts the USB interface power supply, along with the startup of computer with close operation and stop.Although this keyboard is saved on the energy relatively, because be subject to the restriction of usb data line, cause keyboard to be limited in usable range.

Wireless Keyboard is because solved the limitation of wired keyboard on usage space by wireless technology, but Wireless Keyboard so just causes keeping with a large amount of batteries the normal operation of keyboard because need to go to realize data transmission by bluetooth or other wireless technologys.

In addition, no matter be Wireless Keyboard or wired keyboard because oversize, and need occupy certain desktop usage space, so also cause the less user's of desktop usage space puzzlement.

The utility model content

The purpose of this utility model is that a kind of tumbler that provides for asking of prior art existence is wireless, and this keyboard both can have been avoided the serious problem of Wireless Keyboard power consumption, can overcome again the drawback that takes up room when keyboard does not use.

The purpose of this utility model is achieved in that

A kind of tumbler Wireless Keyboard, characteristics are that this keyboard comprises rotation axis and keyboard body, and rotation axis is C type cylindrical tube, and the keyboard body is embedded on the rotation axis; The circular arc one side inwall of described rotation axis is provided with several scalloped recess vertically, be respectively equipped with derby in several scalloped recess, circular arc one side of rotation axis vertically middle part is provided with the battery accommodating storehouse, is provided with horizontal Electronic Control chip and wireless blue tooth chip in opening one side of rotation axis; The rotation axis two ends are respectively equipped with the annular LED lamp; Keyboard body upper surface is provided with several buttons.

Described horizontal Electronic Control chip, wireless blue tooth chip and LED lamp hold the storehouse by wire connected battery.

Rotation axis two ends symmetry 1/3rd length that are distributed as of described scalloped recess are respectively established a scalloped recess, and middle part 1/3rd length are respectively established a scalloped recess with rotational symmetry.

The utility model both can have been avoided the serious problem of Wireless Keyboard power consumption, can overcome again the drawback that takes up room when keyboard does not use; Simple in structure, easy to use.

Embodiment

Consult accompanying drawing, the utility model comprises rotation axis 1 and keyboard body 9, and rotation axis 1 is C type cylindrical tube, and keyboard body 9 is embedded on the rotation axis 1; The circular arc one side inwall of rotation axis 1 is provided with several scalloped recess vertically, and several scalloped recess are distributed as: rotation axis 1 two ends symmetry 1/3rd length are respectively established a scalloped recess, and middle part 1/3rd length are respectively established a scalloped recess with rotational symmetry; Be respectively equipped with derby 3, derby 6 and derby 7 in each scalloped recess, circular arc one side of rotation axis 1 vertically middle part is provided with battery accommodating storehouse 4, is provided with horizontal Electronic Control chip 11 and wireless blue tooth chip 12 in opening one side of rotation axis 1; An annular LED lamp 2 is established respectively at rotation axis 1 two ends; Keyboard body 9 upper surfaces are provided with several buttons 13; Described horizontal Electronic Control chip 11, wireless blue tooth chip 12 and LED lamp 2 hold storehouse 4 by wire connected battery.

Upright under the utility model normal condition, when need use, keyboard body 9 to be depressed, built-in electronic horizon chip 11 can be opened keyboard power because of the change of horizontal location of the center of gravity, connect the wireless blue tooth receiver, the LED lamp also will be lit to point out keyboard to enter duty.At this moment, because most of center of gravity of keyboard in the outside of keyboard axle, so just causes the center of gravity of keyboard uneven, thereby cause the whole potential energy of keyboard to increase; After using keyboard, only need unclamp both hands, for the center of gravity that makes keyboard restores balance, potential energy just can force the keyboard center of gravity to return to initial erectility, and simultaneously, the electronic horizon chip 11 of keyboard also can be cut off the electricity supply because of the recovery of horizontal location of the center of gravity.
