Computer keyboard

Technical Field

The invention relates to the field of computer hardware, in particular to a computer keyboard.

Background

The keyboard is the most important input device of the computer, and the performance of the keyboard directly affects the overall experience effect of the computer. When a plurality of people use the keyboard, the conditions of inaccurate key pressing and wrong letter typing can occur, the reason is firstly unfamiliar with the key of the keyboard, and the problem needs long-time operation proficiency to be solved; there are also objective reasons that the keys of the keyboard have many drawbacks in design.

Although the existing keyboards on the market have large and small overall structures and various styles, the existing keyboards are identical in key design, each key is in a fixed position, the distance between the keys cannot be adjusted, and the key layout of the keyboard cannot be adjusted in a personalized manner. Particularly, for game enthusiasts, the requirement on the key pressing speed is particularly high, however, the fingers of each player are different in length, for example, players with large hands and long fingers can be particularly awkward when pressing keys to influence the operation, so that it is very important to find a keyboard suitable for the hand type of the player.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings and the embodiments.

Referring to fig. 1-3, a computer keyboard comprises a main body 100, a circuit board 200 in the main body 100, and a plurality of key devices 300, wherein each key device 300 comprises a key cap 301, a press rod 302 is connected to the lower end of the key cap 301, the key device 300 further comprises a key slot 303 located below the press rod 302, the upper end of the key slot 303 is divided into an N × N grid 304 structure, and each grid 304 can be used for embedding the press rod 302. In use, the plunger 302 can be inserted into any of the panes 304 as desired, depending on its fit, so that the position of each key cap 301 is different. The lower end of the key position groove 303 is provided with a foil layer 305, two contacts 201 are arranged below the foil layer 305, and the contacts 201 are connected to the circuit board 200. The four corners of the lower surface of the foil 305 are connected with cylinders 306, the cylinders 306 penetrate through the circuit board 200, and the cylinders 306 are sleeved with return springs 307.

When a user presses the key cap 301, the pressing rod 302 presses the key groove 303 downwards, so that the foil layer 305 presses downwards and contacts the two contacts 201, the circuit of the key on the circuit board 200 is completed, and the key information is input into the computer. Then when the hand is released, the return spring 307 rebounds, restoring the key cap 301.

Preferably, a fixing post 308 is connected to the middle of the lower surface of the foil layer 305, the fixing post 308 penetrates through the circuit board 200, a protection block 202 is arranged at a corresponding position on the lower surface of the circuit board 200, a circular hole is formed in the protection block 202 from top to bottom, and the lower end of the fixing post 308 is sleeved by the protection block 202. Because the underlying foil layer 305 is subject to non-centering forces when we insert the plunger 302 into the edge grid 304 adjacent the keyway 303, which results in the foil layer 305 being depressed on one side and not on the other side, which prevents both contacts 202 from contacting the foil layer 305 at the same time, the circuit is not completed and the key is often awkward. The design of the invention fully ensures that the fixing column 308 does not laterally displace when pressed, ensures that the foil layer 305 does not incline and press downwards, ensures that the keyboard can be operated more smoothly without infarction, has soft hand feeling and longer service life.

Preferably, a layer of elastic foam 309 is disposed in the middle of the key slot 303, and the elastic foam 309 divides the key slot 303 into an upper portion and a lower portion. Therefore, after the foil layer 305 is contacted with the contact 202, the key cap 301 has a buffering process, namely the contact 202 and the foil layer 305 are protected from being abraded, the operation hand feeling is softer, and an operator has better operation experience.

Preferably, the upper surface of the keycap 301 is coated with the antibacterial coating 310, and the antibacterial coating 310 is Al₂O₃Wear-resistant layer of Al₂O₃Nano TiO is added in the wear-resistant layer₂A photo-oxidant. When TiO is present₂After being irradiated by the sun, can be excited to generate superoxide ion free radicals (O)₂ ^—) And hydroxyl radicals (. OH), which readily penetrate the cell wall of bacteria. When bacteria are adsorbed on the keycap 301 coated with the antibacterial coating 310, their cell membrane materials are rapidly damaged, thereby preventing the transmission of the bacterial cell membrane materials, and thus effectively killing the bacteria. Therefore, the keyboard can be effectively sterilized only by occasionally placing the keyboard in the sun for a period of time at ordinary times.

In the following description of the embodiment, the N × N square grid 304 structure is a 3 × 3 square grid 304 structure:

many game operations will use letter keys on the keyboard near the left, so we have experimented with selecting three columns of letter keys on the keyboard near the left: q, W, E, A, S, D, Z, X and C.

1	2	3
			4	5	6
7	8	9

As shown in the table above, the press lever 302 of the Q key is fitted into the square lattice shown in the number 1, the press lever 302 of the W key is fitted into the square lattice shown in the number 2, the press lever 302 of the E key is fitted into the square lattice shown in the number 3, the press lever 302 of the a key is fitted into the square lattice shown in the number 4, the press lever 302 of the S key is fitted into the square lattice shown in the number 5, the press lever 302 of the D key is fitted into the square lattice shown in the number 6, the press lever 302 of the Z key is fitted into the square lattice shown in the number 7, the press lever 302 of the X key is fitted into the square lattice shown in the number 8, and the press lever 302 of.

The other keys are placed in the square indicated by the number 5 for comparison.

The effect after the installation is as shown in fig. 4, the distance between the left three rows of letter keys is increased, so that the keyboard is suitable for operators with large hands.

Of course, not only the distance between the keys is adjustable, but also some operators have special requirements, such as the left high and the right low of the keys, the convex of the middle key and the like, which can be met.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
