Description
Technical field
The utility model relates to keyboard accessory field, espespecially a kind of variable force key.
Background technique
Keyboard be computer it is the most frequently used be also most important input equipment, by tap keyboard can be by English alphabet, number
Word, punctuation mark etc. are input in computer, to issue order, input data etc. to computer.Keyboard be divided into mechanical keyboard,
Membrane keyboard, electric silica gel keyboard, capacitor keyboard, wherein strong with mechanical keyboard timing, feel, which is used for a long time, will not change depth
Liked by game player.
Currently, mechanical keyboard paragraph sense and pressure is not mainly by using coaxially changing paragraph sense, it is such as common on the market
Black, red, green, four kinds of axis of tea.Black axis paragraph sense is most strong；Red axis there is no paragraph sense；Green axis paragraph sense is smaller, but level
Obviously, apparent rhythm sound is had；Tea axis paragraph sense and green axis are similar, and only stereovision is not strong.If it is desired to impression is different
Feel, user must buy the mechanical keyboard of different colours axis.If not knowing that the hobby of oneself is easy to purchase and is not suitable for
The mechanical keyboard of oneself, to cause user's repeat buying, cost of idleness.It can not equally like according to oneself and define mechanical axis
Paragraph sense and dynamics.
To solve the above problems, applicant discloses a kind of magnetic press key (publication No. CN107785202A), including it is outer
The top of shell and the middle shaft body in shell, the middle shaft body is equipped with keycap seat, and the bottom of the middle shaft body is protruded into

Embodiment one
Fig. 1-4 is please referred to, the utility model is about a kind of variable force key, including shell 1, axis 2, magnet ring 3, electromagnet
4, the axis 2 protrudes into the shell 1, and the top of axis 2 is fixedly installed keycap seat 23, the bottom end of the axis 2 and outer
Reset spring 5 is equipped between the inner bottom surface of shell 1, axis 2 can move back and forth along the vertical direction in shell 1, the bottom of the axis 2
End is further fixedly arranged on locating part 6, and hollow cylinder can be set into locating part 6, and the outer wall of 6 bottom end of locating part is circumferentially
Equipped with flange 62, the magnet ring 3 is socketed in 6 outer wall of locating part and is located at 62 upper end of flange, and magnet ring 3 is along limit
The bottom in shell 1 is arranged in the permanent magnet of 6 axial charging of part, the electromagnet 4, and when the movement of 2 downlink of the axis, described
Electromagnet 4 can penetrate inside the locating part 6, and the size of current of the electromagnet 4 and direction are adjustable.
Since magnet ring is socketed or is arranged inside locating part, when the compression of keycap seat moves down, electromagnet can penetrate the limit
Inside the part of position, the distance of electromagnet and magnet ring is overlapped or separate, so that a variety of variable force control modes can be realized.
Several control modes are explained below.
(1) in its natural state, magnet ring 3 due to gravity along locating part 6 move down after be fitted in the convex of 6 bottom end of locating part
On edge 62, so that the distance of magnet ring 3 and electromagnet 4 becomes smaller.
When applying a pressure to keycap seat 23, axis 2 drives locating part 6 to move downward, after the positive energization of electromagnet 4,

41 are welded with control circuit board 7, compared to the docking mode for designing elastic slice and leg 41 in conventional enclosure 1, the present embodiment
Connection type it is more convenient and secured.
In the present embodiment, the medial surface of the shell 1 is equipped with sliding slot 12 along the vertical direction, and the axis 2 is equipped with and cunning
The corresponding sliding block 21 of slot 12, and the sliding block 21 is slidably connected with the sliding slot 12.
Sliding block 21 is slidably matched with sliding slot 12, provides guiding role for the movement of axis 2, makes the movement of axis 2 more
Exactly.
In the present embodiment, the locating part 6 is several circular arc blocks 61 arranged in the form of circumference array.
Locating part 6 is formed by the circular arc block 61 that several along the circumferential direction spacing are arranged, the material of locating part 6 can be saved
Material, while mitigating the weight of keycap seat 23.
In the present embodiment, the bottom end of the axis 2 is equipped with guide post 22, and the bottom end of the shell 1 is equipped with and the guide post 22
Corresponding guide sleeve 17, the guide post 22 are plugged in the guide sleeve 17, and the reset spring 5 is socketed on 22 table of guide post
Face.
It is moved by guide post 22 along guide sleeve 17, guarantees that the elastic force effect of reset spring 5 is along vertical direction, to make axis
2 reset exactly.
In the present embodiment, the shell 1 includes pedestal 13 and upper cover 14, and the lateral surface of the pedestal 13 is equipped with fixture block 15,
