Detailed Description

The present invention will be described in further detail below.

As shown in fig. 1 to 3, a keyboard comprises a keyboard base 1, wherein the keyboard base 1 is provided with a plurality of key caps 2, the height of the keyboard base 1 is gradually increased from one end of the keyboard base 1 to the other end of the keyboard base 1, each key cap 2 comprises a first cap body 21 and a second cap body 22 which are connected with each other, the first cap body 21 is close to one end of the keyboard base 1, the second cap body 22 is close to the other end of the keyboard base 1, and the height of the first cap body 21 is greater than the height of the second cap body 22.

In the prior art, when a long fingernail person types, the fingernails often touch adjacent keys due to the arrangement mode of the keycap 2 surface and the tight keycap 2 which tend to be flat, the abrasion of the fingernails is accelerated, and the problems of mistaken touch, noise, fingernail clamping between key gaps and the like are caused.

The utility model discloses in, keyboard seat 1 highly increases to the 1 other end of keyboard seat by 1 one end of keyboard seat gradually for keyboard seat 1 is increased gradually to the other end of keeping away from user's wrist by the one end that is close to user's wrist, presents for from near and far-away ground tilt up, accords with the ergonomic design, and convenience of customers contacts button far away.

Because the first cap body 21 of the key cap 2 is close to one end of the keyboard base 1, the second cap body 22 is close to the other end of the keyboard base 1, and the height of the first cap body 21 is greater than that of the second cap body 22, a height difference is formed between the first cap body 21 and the second cap body 22, and a concave part is formed between the first cap body 21 of the key cap 2 and the first cap body 21 of the adjacent key cap 2 in front. The long nail personage uses the finger abdomen to press down key cap 2 when typing, and long nail falls in depressed part position top, is difficult to the mistake and touches adjacent key cap 2 in the place ahead, and nail mistake when effectively reducing long nail's user to type is touched other buttons, the nail is pressed the button and is sent noise, nail wearing and tearing, nail card scheduling problem in the gap between the button, can not produce the mistake input, has effectively promoted typing efficiency.

The height of the second cap body 22 is 1/2-3/4 of the height of the first cap body 21.

Within this range of values, it is possible to secure the connection strength between the first cap body 21 and the second cap body 22 and to reserve a sufficient space for the long nail.

The joint of the first cap body 21 and the second cap body 22 is provided with an arc chamfer.

The sharp chamfer at the joint of the first cap body 21 and the second cap body 22 is eliminated by the arrangement of the arc chamfer, and the user experience is improved.

The area of the end surface of the first cap body 21 is larger than that of the end surface of the second cap body 22.

The larger area of the end surface of the first cap 21 can improve the accuracy of the user's keystrokes if the recessed position above the second cap 22 is sufficient to accommodate a long fingernail.

The height of the first cap body 21 is gradually increased from one side close to one end of the keyboard holder 1 to one side close to the other end of the keyboard holder 1.

Specifically, the included angle between the upper end surface of the first cap 21 and the bottom surface of the keyboard seat 1 is alpha, and alpha is larger than 0 degree and less than or equal to 15 degrees. The proper included angle promotes the comfort of the finger abdomen stretching key.

The cross section of the keycap 2 is rectangular.

The keycap 2 with the rectangular cross section has a large surface area, and the keystroke accuracy of a user can be improved. The side view of key cap 2 is "L" font, has a square breach in comparison square face, under the condition that furthest does not change user's typing custom, has great space to hold its longer nail. The area of the end face of the first cap body 21 of the key with the L-shaped cross section is reduced, the size of the minimum end face of the first cap body 21 of the key cap 2 is controlled to be 12.0 x 14.4mm by considering ergonomic factors and combining the size of the minimum surface of the key of a commercially available keyboard, and the use comfort of a user is guaranteed.

The keyboard base 1 is provided with a support 3, one end of the support 3 is hinged to the side part of the keyboard base 1, the support 3 at least has a first state and a second state, and in the first state, the other end of the support 3 is positioned on one side of the other end of the keyboard base 1 and corresponds to one end of the keyboard base 1; in the second state, the other end of the stand 3 is located below the key pad 1.

Specifically, one end of the support 3 is a connecting lug, and the other end is a cross bar. The engaging lugs are two in number and are respectively connected to two ends of the cross rod. The cross rod and the two connecting lugs are integrally formed, and the two connecting lugs are respectively arranged on two sides of the keyboard base 1 and are respectively hinged to the keyboard base 1 through the rotating shaft 4. In the first state, the cross bar is positioned at the front end of the keyboard base 1; in the second state, the cross bar is padded below the keyboard base 1, the height of the other end of the keyboard base 1 is increased, and the inclination angle of the keyboard base 1 is changed. Through the switching of the two states, the requirements of different users on different inclination angles of the keyboard base 1 can be met.

In the prior art, the support 3 of the keyboard base 1 is generally designed to be buried in the bottom of the keyboard base 1, and a user lifts the keyboard base 1 to find the support 3 first and then pulls the support out from the bottom of the keyboard base 1, so that the support can be used, and therefore the support is not convenient for long-nail people to use. The utility model discloses a support 3 is non-hidden "" font, and semi-winding is at keyboard seat 1 front end, and the user can pull it in order to adjust keyboard seat 1 height. Improve the support 3 with keyboard seat 1 for encircleing the surrounding type support 3 of keyboard seat 1 front end by traditional buried support 3, this action with the user when using keyboard support 3 the action of finger "digging out" support 3 become the action of "pulling", use more swiftly laborsaving, and this scheme has increased the 3 areas of support, prevents more effectively that keyboard seat 1 from sliding.

Aiming at the use of multimedia and the requirements of mobile office, the keyboard base 1 is also provided with a shortcut key 5 for adjusting the volume of a computer and the brightness of a screen, a Bluetooth switch 6 and a corresponding indicator light 7, and can be connected with mobile equipment through Bluetooth to realize mobile office. The use of combination keys and other input modes by a user is reduced, and the input efficiency and the use experience are improved. When the Bluetooth is used, the Bluetooth switch 6 is pressed for a long time, and the indicator light 7 flickers to be orange; but bluetooth automatic search jointing equipment, connect the completion back, pilot lamp 7 is often bright, is blue. If the connection fails, the indicator light 7 is normally on and orange, and the user can press the bluetooth switch 6 twice in succession to reconnect. When the Bluetooth is not needed, the Bluetooth switch 6 is pressed for a long time to be closed, and the indicator light 7 is turned off after the Bluetooth is closed.

The shell and the keys of the keyboard base 1 are made of low-purity colors and plastic materials, and the overall shape is mellow and lovely.

The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be equivalent replacement modes, and all are included in the scope of the present invention.
