Example 1

The present embodiment provides a magnet-based key-press structure, referring to fig. 1-3.

The basic mode of the utility model is as follows:

the pressing key structure based on the magnet comprises an axle center 102, an axle body 103, a first magnet 105 and a second magnet 106;

the shaft center 102 is of a columnar structure, a first chamber 104 is arranged at the bottom of the shaft center 102, and the first magnet 105 is clamped in the first chamber 104;

the shaft body 103 is of a hollow polyhedral structure, the bottom of the shaft center 102 extends into the shaft body 103, and the shaft center 102 is slidably connected with the shaft body 103;

a second chamber 107 is arranged in the shaft body 103, and the second magnet 106 is clamped in the second chamber 107;

the first magnet 105 and the second magnet 106 are disposed opposite to each other, the relative positions of which are shown in fig. 3, and the polarities of the first magnet 105 and the second magnet 106 are the same.

The working principle of this embodiment is as follows:

it is first specifically described that, for convenience and practicality, a key cap 101 is generally provided, an axle center 102 is detachably mounted at the bottom of the key cap 101,

the key cap 101 in this embodiment, like a common key cap, can be printed with symbols, letters, and other contents conforming to the usage scenario for the user to directly press, and after the key is pressed, the axle center 102 slides downward along the axis body 103, that is, the axle center 102 moves downward along the axis 102 along the axis direction together with the key cap 101 connected thereto, and other circuits of the linkage keyboard and other structures realize the key-in function, and related circuit designs are consistent with those of the conventional keyboard, and are not described here. After pressing, the oppositely disposed first magnet 105 and second magnet 106 are brought close together.

After the key is completely entered, the user releases the key cap 101 of the key by fingers, and as the polarities of the first magnet 105 and the second magnet 106 are the same, a vertical repulsive force exists between the first magnet 105 and the second magnet 106, and under the action of the interaction force, the first magnet 105 is lifted upwards, so that the axle center 102 slides upwards along the axial direction of the axle body 103, that is, the axle center 102 moves upwards along the axial direction of the axle center 102 together with the key cap 101 connected with the axle center 102, and reset after pressing is realized. Specifically, the shaft center 102 and the shaft body 103 are prevented from coming off the shaft body 103 by a stopper structure between the shaft center 102 and the shaft body 103.

In general, the embodiment adopts the matching of the two magnets to replace the elastic component in the traditional keyboard to replace the reset after the key is pressed, so that the problems of limited service life and limited use effect of the elastic component are avoided, the service life of the keyboard is prolonged, and the rebound failure rate is reduced; in addition, the adopted magnets can realize pressing rebound by utilizing the repulsion of the same poles, the pressing rebound effect is excellent, the pressing and rebound performances can be ensured, and the service life is prolonged;

secondly, in this embodiment, the first magnet 105 and the second magnet 106 are respectively clamped by the first chamber 104 and the second chamber 107, and the positions of the magnets are fixed by the chambers, so that the first magnet 105 and the second magnet 106 are prevented from being displaced in the horizontal direction, and if the first magnet 105 and the second magnet 106 are displaced horizontally, the first magnet 105 and the second magnet 106 are caused to be displaced in a position deviation, so that the mutual acting force is affected; in particular, in order to ensure normal sliding, the upper portion of the shaft body 103 needs to be inserted into the key cap 101 during sliding, so that the outer diameter of the upper portion of the shaft body 103 is smaller than the inner diameter of the key cap 101.

Finally, the embodiment can be realized through simpler arrangement, has lower manufacturing cost and is easy to implement and popularize.
