Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application can be combined with each other without conflict, and the present invention is further described in detail with reference to the drawings and specific embodiments.

If directional indications (such as up, down, left, right, front, and rear … …) are provided in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the movement, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indications are changed accordingly.

In addition, the descriptions related to "first", "second", etc. in the present invention are only used for descriptive purposes and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

Referring to fig. 1 to 4, a tablet computer key with balanced key strokes according to an embodiment of the present invention includes a key cap, a tablet computer substrate, a key device, a left cantilever, and a right cantilever.

The key cap bottom both sides are protruding left ear and the right ear portion of being equipped with respectively, and the one end of left cantilever and right cantilever all is through a pivot A respectively around locating left ear and right ear on, and the other end of left cantilever and the other end of right cantilever are connected through a pivot B. The middle parts of the left cantilever and the right cantilever are arranged on the tablet computer substrate through a rotating shaft C. A pressing part is convexly arranged in the middle of the bottom end of the keycap, and the key device is correspondingly arranged below the pressing part; the distance from the center of the rotating shaft A to the top end surface of the keycap is smaller than the distance from the center of the rotating shaft C to the top end surface of the keycap.

As an implementation mode, notches corresponding to the rotating shafts A are formed in the inner sides of the left ear part and the right ear part, and the rotating shafts A on one ends of the left cantilever and the right cantilever are correspondingly arranged in the notches of the left ear part and the right ear part respectively. One end of each of the left cantilever and the right cantilever is provided with a rotating shaft A.

As an implementation mode, the other end of the left cantilever and the other end of the right cantilever are respectively provided with a rotating shaft B and a notch, and the rotating shaft B is arranged in the notch.

As an implementation mode, shaft holes are formed in the middle parts of the left cantilever and the right cantilever, and the rotating shaft C is correspondingly arranged in the shaft holes. The rotating shaft C is arranged on the panel computer substrate.

As an implementation mode, the outer sides of the left ear part and the right ear part exceed the two sides of the keycap for limiting and preventing the keycap from falling off the tablet personal computer.

The working principle of the utility model is as follows: when one side of the keycap is pressed, for example, the left side is pressed, the left side of the keycap downwards drives the left end of the left cantilever downwards, the left cantilever rotates around the rotating shaft C on the left side according to the lever principle, the right end of the left cantilever upwards drives the left end of the right cantilever upwards; according to the lever principle, the right cantilever rotates around the rotating shaft C on the right side, and then the right end of the right cantilever is driven to be downward, so that the right side of the keycap is downward, balance of key strokes is achieved, and a user can keep consistent hand feeling no matter where the keycap is pressed.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
