Detailed Description
In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1 to 3, the key cap hidden keyboard is shown in an unfolded state in normal use as shown in fig. 1, and the key cap hidden state as shown in fig. 2; when a user needs to hide the key 1 to a position 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 62 is driven by the rotating force of the motor to descend along the riveting column 51 on the supporting plate, so that the supporting plate 5, the printed circuit board and the key module 2 are integrally moved, and finally the key is lowered to a position flush with the plane of the keyboard upper cover, thereby greatly reducing the thickness of the mechanical keyboard and facilitating carrying and storage; it can be understood that when the keyboard is required to be normally used, the user triggers the keycap lifting switch again, and the rotating force of the motor drives the screw rod to ascend along the riveting column on the supporting plate, so that the keycap protrudes above the plane of the upper cover of the keyboard, and the normal use state is achieved. 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; the motor (ELECTRIC MACHINERY, commonly called as a motor) refers to an electromagnetic device for converting or transmitting electric energy according to the law of electromagnetic induction, and can be a stepping motor; the printed circuit board and the supporting plate are bonded through double-sided adhesive tape, for example, 3M adhesive is adopted; the upper keyboard cover and the lower keyboard cover 7 are fixedly connected through screws 8.
Further, in one embodiment, as shown in fig. 3, the key module 2 includes: a key cap module 21 and a key switch 22, wherein the key cap module is covered on the key switch. The key cap module is the sum of 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 are in one-to-one correspondence with the key caps in number and positions. Because the key switch and the key cap module are independently detachable, when the key caps are worn, the maintenance and the replacement are convenient, or the user adopts the key caps with different colors for some keys according to individual 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 upper cover 6. The cover plate made of the same material is stuck on the key cap module and the keyboard upper cover, so that when the key cap is hidden to a position flush with the keyboard upper cover, the whole keyboard surface is smooth and flat, gaps between the key cap and the keyboard upper cover can be reduced, and dust is prevented from entering. Wherein, the apron can adopt glass apron.
Further, in one embodiment, as shown in fig. 3, the PC character piece 24 is attached to the inner surface of the key cap module 21; LED lamps 42 are distributed on the printed circuit board; the cover plates with the same material adopt light-permeable cover plates. The PC character piece is a sheet printed with key characters, a PC paint spraying laser carving process is adopted for the PC character piece, the required characters are laser carved on the sheet, and the position of the keyboard upper cover 6 corresponding to the PC character piece is hollowed out; the LED lamps are distributed on the printed circuit board, and can be particularly distributed at four corners and the central axis of the printed circuit board; the cover plate stuck on the key cap module and the upper cover of the keyboard is a transparent cover plate, such as a black transparent glass cover plate.
When the LED lamp is lighted, the LED can project the characters on the PC character sheet onto the transparent glass cover plate, and the key characters are presented in front of eyes of a user, so that the use of the user is facilitated; and when the LED lamp is not lightened, the keyboard surface does not display key characters, so that the keyboard surface presents an integrated color, and the visual impact is strong.
Further, in an embodiment, the supporting plate 5 is made of metal. Because the quality of mechanical keyboard, especially its key switch part is heavier than ordinary keyboard, so, adopts the backup pad that metal material was made, is favorable to playing fine supporting role to printed circuit board and key switch, and the keyboard is unstable when can avoiding fast or powerful typing, simultaneously for the key cap is at the in-process of lift, 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 a wired manner, for example, through a USB connection 412; or by wireless means, for example using a bluetooth module 411. The Bluetooth module can be arranged on the printed circuit board, the complex wiring of the mode can be saved, the mode is simpler than the 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 on four corners of the bottom of the keyboard lower cover, can be made of flexible materials such as rubber and the like, and have a fixing effect on the keyboard, so that the keyboard is prevented from sliding on a smooth desktop in the typing process.
The hidden keyboard of the key cap of the present invention has been described above to help understand the present invention, but the implementation of the present invention is not limited by the above embodiments, and any changes, modifications, substitutions, combinations, and simplifications made without departing from the principles of the present invention should be equivalent substitution manner, and are included in the protection scope of the present invention.
