Embodiment 1

[0026] See figure 1 , figure 2 as shown,

[0027] figure 1 It is a structural schematic diagram of the permanent magnet button in the embodiment of the present invention.

[0028] figure 2 It is a top view of the back of the key cover in the embodiment of the present invention.

[0029] A permanent magnet button provided by the present invention includes a key cap 1, a key base 2, a pressing device 3 and a key cover 4. The key cap 1 is fastened to the key base 2 to form a storage cavity for placing the pressing device 3 after the fastening. The storage cavity is open at the top and is square.

[0030] The pressing device 3 includes a rectangular base 31, the upper end of which is a cross-shaped cylinder 32. A group of opposite sides of the base 31 extend outwards to form two opposite sides that are narrow at the top and wide at the bottom, and are respectively provided with The slider 33, the slider 33 is a raised structure, the rectangular base 31 is provided with a t...

Embodiment 2

[0039] See image 3 , Figure 4 as shown,

[0040] image 3 It is a position diagram of the first group of permanent magnets and the second group of permanent magnets under normal conditions in the embodiment of the present invention.

[0041] Figure 4 It is a position diagram of the first group of permanent magnets and the second group of permanent magnets in the pressed state in the embodiment of the present invention.

[0042] The difference between a permanent magnet button in the embodiment of the present invention and the permanent magnet button in Embodiment 1 is that the second group of permanent magnets includes a first permanent magnet 23 and a second permanent magnet 24, and the first permanent magnet 23 The first permanent magnet 35 and the second permanent magnet 24 are respectively arranged on a group of opposite sides of the square structure of the base 2 , and under normal conditions, the first permanent magnet 35 is between the first permanent magnet 23 a...

Embodiment 3

[0044]The difference between a permanent magnet button in the embodiment of the present invention and the permanent magnet button in Embodiment 1 is that the second group of permanent magnets 23 includes a first permanent magnet, a second permanent magnet and a third permanent magnet, and the normal The lower first group of 35 permanent magnets is between the first permanent magnet, the second permanent magnet and the third permanent magnet.

Abstract

The invention discloses a permanent magnet button. The permanent magnet button comprises a key cap, a key seat and a pressing device and is characterized in that the pressing device comprises a touch column, a first group of permanent magnets is arranged at the bottom of the touch column, a second group of permanent magnets is arranged at the key seat, and in a normal state, the N / S poles of the first group of permanent magnets can be placed in parallel to the N / S poles of the second group of permanent magnets, or the S / N poles of the first group of permanent magnets can be placed in parallel to the S / N poles of the second group of permanent magnets; and the first group of permanent magnets can move up and down between the key seats along with the touch column to switch on and off the button. Compared with the prior art, the permanent magnet button has the advantages of simple structure and long service life; meanwhile, the pressing device is provided with two groups of permanent magnets, and the button is switched on and off under the action of opposite-pole attraction among the permanent magnets, so that the hand feel is good, and a user does not feel fatigue when using the button for long time.

Description

technical field [0001] The invention relates to the technical field of permanent magnet buttons, in particular to a permanent magnet button. Background technique [0002] In the prior art, a keyboard switch is a main component of a keyboard, which is an important input device for computers and various automation equipment. The existing keyboard switches include mechanical keys and membrane keys. The structure of the mechanical button includes a spring cap or keycap socket, a spring, and at least one piece of shrapnel. The assembly accuracy is high, and there is no positioning device. The shrapnel must be welded one by one to achieve electrical connection. , so the assembly is extremely laborious, time-consuming, labor-intensive, and the cost is increased; while the thin-film button has a small knocking sound, no welding is required, and there is no elastic fatigue phenomenon of the shrapnel, but the pressing touch and the appropriate amount of knocking sound produced by the ...
