Abstract
A kind of button, comprise pressing piece, the first magnet, the second magnet and circuit board, described circuit board is arranged at described the second magnet middle part, described the first magnet correspondence is arranged at described the second magnet top, the first magnet is arranged at described pressing piece below, and described the first magnet and described the second magnet mutual exclusion arrange.Adopt the utility model, two magnets that arrange by mutual exclusion are realized pressing piece and are pressed and reset, long service life, and do not produce mechanical friction, and noiselessness, result of use is good.
Description
Technical field
The utility model relates to input equipment technical field, is specifically related to a kind of button.
Background technology
Input equipment of the prior art is all mechanical key, by flexible member fixedly pressing piece and circuit board, realize pressing piece vertically to reciprocating motion, but there is larger problem in it, the mechanical key life-span is short, uses after a period of time, and flexible member occurs tired, causing after button pressed cannot resilience, and then cannot use.
Therefore,, for problems of the prior art, need badly and provide the technology of long button of a kind of easy to use, life-span particularly important.
Summary of the invention
The purpose of this utility model is to avoid weak point of the prior art and long button of a kind of easy to use, life-span is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of button is provided, comprise pressing piece, the first magnet, the second magnet and circuit board, described circuit board is arranged at described the second magnet middle part, described the first magnet correspondence is arranged at described the second magnet top, the first magnet is arranged at described pressing piece below, and described the first magnet and described the second magnet mutual exclusion arrange.
Wherein, the cross section of described the second magnet is " returning " type.
Wherein, be provided with limiting plate, described limiting plate is provided with installing hole, and described pressing piece and described the first magnet are arranged in described installing hole.
Wherein, described pressing piece is provided with boss, and described pressing piece is arranged in described installing hole by boss.
Wherein, the surface area of described the first magnet is greater than the area of described installing hole.
The beneficial effects of the utility model:
A kind of button, comprise pressing piece, the first magnet, the second magnet and circuit board, described circuit board is arranged at described the second magnet middle part, described the first magnet correspondence is arranged at described the second magnet top, the first magnet is arranged at described pressing piece below, and described the first magnet and described the second magnet mutual exclusion arrange.
Adopt the utility model, two magnets that arrange by mutual exclusion are realized pressing piece and are pressed and reset, long service life, and do not produce mechanical friction, and noiselessness, result of use is good.
Accompanying drawing explanation
The utility model is described in further detail to utilize accompanying drawing, but embodiment in accompanying drawing does not form any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of button of the present utility model.
At Fig. 1, comprise:
1---pressing piece, 2---circuit board, 3---the second magnet, 4---the first magnet, 5---limiting plate, 6---boss.
Embodiment
Below in conjunction with embodiment, the utility model is elaborated.
Embodiment 1
A kind of button, as shown in Figure 1, comprise pressing piece 1, the first magnet 4, the second magnet 3 and circuit board 2, described circuit board 2 is arranged at described the second magnet 3 middle parts, described the first magnet 4 correspondences are arranged at described the second magnet 3 tops, the first magnet 4 is arranged at described pressing piece 1 below, described the first magnet 4 and described the second magnet 3 mutual exclusion settings.
Adopt the utility model, two magnets that arrange by mutual exclusion are realized pressing piece 1 and are pressed and reset, long service life, and do not produce mechanical friction, and noiselessness, result of use is good.
Concrete, the cross section of described the second magnet 3 is " returning " type.The second magnet 3 of hollow structure, can form repulsion with the first magnet 4 integral body, and pressing piece 1 is resetted, and pressing piece 1 is stressed evenly can not stand up inclination, causes card key.
Wherein, be provided with limiting plate 5, described limiting plate 5 is provided with installing hole, and described pressing piece 1 is arranged in described installing hole with described the first magnet 4, and described pressing piece 1 is provided with boss 6, and described pressing piece 1 is arranged in described installing hole by boss 6.
Easy-to-use, be difficult for card key.
Wherein, the surface area of described the first magnet 4 is greater than the area of described installing hole.
Finally should be noted that; above embodiment is the restriction in order to the technical solution of the utility model to be described but not to the utility model protection range only; although the utility model is explained in detail with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical solution of the utility model, and not depart from essence and the scope of technical solutions of the utility model.
