Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A key cap hidden keyboard is shown in figures 1 to 3, wherein the keyboard is in an unfolded state in normal use as shown in figure 1, and in a hidden state as shown in figure 2; when a user needs to hide the keys 1 to the position which is flush with the plane of the keyboard upper cover 6, the key cap lifting switch 3 is triggered, so that the IC on the printed circuit board 4 receives a trigger signal and controls the motor 61 on the inner surface of the keyboard upper cover to rotate, the screw rod 62 is driven by the rotating force of the motor to descend along the riveting column 51 on the supporting plate, the supporting plate 5, the printed circuit board and the key module 2 are integrally moved, and finally the keys are descended to the position which is flush with the plane of the keyboard upper cover, so that the thickness of the mechanical keyboard is greatly reduced, and the mechanical keyboard is convenient to carry and store; when the keyboard is normally used, a user triggers the key cap lifting switch again, the screw rod is driven by the rotating force of the motor to ascend along the riveting column on the supporting plate, and the key cap protrudes out of the plane of the upper cover of the keyboard to achieve a normal use state. The key cap lifting switch can be a key cap key or a key cap lifting button which is independently designed on the surface of the key cap; an Electric machine (commonly called as a "motor") refers to an electromagnetic device that converts or transmits Electric energy according to the law of electromagnetic induction, and may be specifically a stepping motor; the printed circuit board and the support plate are bonded by double-sided adhesive tape, for example, 3M adhesive tape; the keyboard upper cover and the keyboard lower cover 7 are fixedly connected through screws 8.

Further, in an embodiment, as shown in fig. 3, the key module 2 includes: a key cap module 21 and a key switch 22, the key cap module covers the key switch. The key cap module is the sum of the key caps of all keys on the keyboard; the key switches are mechanical switches of the mechanical keyboard, each key switch represents a key, and the key switches correspond to the keycaps in number and position one by one. Because the key switch and the key cap module are independent and detachable, when the key cap is worn, the key switch is convenient to maintain and replace, or a user adopts key caps with different colors for some keys for personalized requirements.

Further, in one embodiment, as shown in fig. 3, a cover plate 23 made of the same material is attached on the key cap module 21 and the keyboard top cover 6. Paste the apron of same material on the key cap module and the keyboard upper cover for when the key cap hide the position with keyboard upper cover parallel and level, whole keyboard surface is smooth level and smooth, and can reduce the gap between key cap and the keyboard upper cover, avoid the dust to get into. Wherein, the cover plate can adopt a glass cover plate.

Further, in one embodiment, as shown in fig. 3, the inner surface of the key cap module 21 is pasted with a PC character piece 24; LED lamps 42 are distributed on the printed circuit board; the cover plate made of the same material adopts a light-permeable cover plate. The PC character piece is a sheet printed with key characters, the PC character piece adopts a PC spray painting laser engraving process, required characters are laser engraved on the sheet, and the position of the keyboard upper cover 6, corresponding to the PC character piece, is hollowed; the LED lamps are distributed on the printed circuit board, and particularly can be distributed at four corners and the position of a central axis of the printed circuit board; the cover plate pasted on the key cap module and the keyboard upper cover is a light-permeable cover plate, for example, a black light-permeable glass cover plate.

When the LED lamp is lightened, the LED light can project the characters on the PC character sheet onto the light-permeable glass cover plate, and the key characters are displayed in front of eyes of a user, so that the use of the user is facilitated; and when the LED lamp is not lighted, the keyboard surface does not display key characters, so that the keyboard surface presents an integrated color and the visual impact sense is strong.

Further, in one embodiment, the supporting plate 5 is made of metal. Because mechanical keyboard, especially its key switch part compare ordinary keyboard's quality heavier, so, the backup pad that adopts the metal material to make is favorable to playing fine supporting role to printed circuit board and key switch, and the keyboard is unstable when can avoiding quick or heavily typing for simultaneously, makes the key cap at the in-process that goes up and down, and whole keyboard is more firm, can not appear rocking.

Further, in one embodiment, as shown in fig. 3, the data connection module may be connected to the computer device by wire, for example, through the USB connection 412; or, the computer device is connected with the wireless mode, for example, by using the bluetooth module 411. The Bluetooth module can be arranged on the printed circuit board, so that the wiring complexity can be reduced, the mode is simpler than a wired connection mode, and the layout space of the keyboard is saved.

Further, in one embodiment, as shown in fig. 3, a keyboard foot pad 71 is attached to the bottom of the keyboard lower cover. The keyboard foot pads are distributed at four corners of the bottom of the keyboard lower cover and can be made of flexible materials such as rubber, so that the keyboard is fixed and prevented from sliding on a smooth desktop in the typing process.

It is right above the utility model discloses the hidden keyboard of key cap has been elucidated for help understands the utility model discloses, nevertheless the utility model discloses an embodiment does not receive the restriction of above-mentioned embodiment, and any does not deviate from the utility model discloses change, modification, substitution, combination, simplification made under the principle all should be equivalent replacement mode, all contain within the protection scope of the utility model.
