Big overcomes the repulsive magnetic force between the 3rd magnetic part 146 and the second magnetic part 126 to press by bonding force
Keycap 140.
When keycap 140 starts to be pressed, as shown in state 2, X support 160 does shearing motion, makes
Obtaining end 162b drives the 3rd magnetic part 146 to slide along with base plate 120 direction that is substantially parallel, thus
3rd magnetic part 146 deviation with the second magnetic part 126 substantially relative to position.As it was previously stated, magnet
Magnetic fidle of end is relatively strong, and dies down rapidly to magnetic field, direction, both sides.So, the 3rd magnetic part 146 gradually takes off
Magnetic line of force close quarters from the second magnetic part 126.In this process, the 3rd magnetic part 146 and second
Repulsive magnetic force between magnetic part 126 is gradually reduced, and can also reduce therewith by bonding force.
It follows that as shown by state 3, keycap 140 continues down to press, until arriving the second place, example
Such as its lowest position.Arriving during the second place, the 3rd magnetic part 146 progresses into and the
The position that one magnetic part 124 is relative.Equally, produce between the first magnetic part 124 and the 3rd magnetic part 146
The magnetic force of raw mutual exclusion.Therefore, the power upwards that the 3rd magnetic part 146 is subject to increases rapidly, and user is wanted
Apply is increased the most rapidly by bonding force.So, user can perceive keycap 140 and has been pressed against
Lower position, and unclamp button finger.In its lowest position, contact stud 142 contacts and is formed on base plate 120

After user unclamps finger, as shown in state 4, keycap 140 is coming from the first magnetic part 124
Under the effect of magnetic repulsion, move up, thus the 3rd magnetic part 146 along return path slide, gradually from
Open the position (as shown in state 5) relative with the first magnetic part 124, and enter and the second magnetic part 126
Relative to position.Final keycap 140 returns to primary importance, enters armed state, as shown in state 6.
Knowable to motion process above, during the button of keyboard 100, due to the 3rd magnetic part 146
Slip, start by bonding force relatively big, then reduce, increase the most again.Therefore, the magnetic force key of the present invention
Dish can realize and feel as rubber blanket keyboard type, the most also has longer service life.
In the embodiment shown in fig. 1, the pivotal connection of X support 160 is substantially at the first bar 162
With the center position of the second bar 164, but, the invention is not restricted to this.As illustrated in figures 4 a and 4b,
Pivotal connection may be located at the first bar 162 and the lower part office (Fig. 4 A) of the second bar 164 or
At upper part (Fig. 4 A).Slip magnetic part (the i.e. the 3rd magnetic part 146) shown in Fig. 1 is set
For being placed in the embodiment of keycap 140 side, the X supporting structure shown in Fig. 4 A is favourable, because
It is provided that longer sliding distance, and the structure design for the present invention brings flexibility.Can be easily geographical
Solving, when slip magnetic part is arranged at base plate 120 side, the X supporting structure shown in Fig. 4 B is preferred
's.
Describe as a example by first, second, and third magnetic part 124,126 and 146 is all permanent magnet above
The present invention one one exemplary embodiment, it will be appreciated by those skilled in the art that the present invention does not limits
In this.Such as, in another one exemplary embodiment of the present invention, first, second, and third magnetic part 124,
126 and 146 can also be all electromagnet.When the first and second magnetic parts 124 and 126 are electromagnet,
It can easily be powered to it by the circuit being formed on base plate 120.Due to the 3rd magnetic part 146
It is arranged at keycap side, needs complicated wiring to its power supply, and in view of the button operation shadow to wiring
Ring, it is advantageous to the 3rd magnetic part 146 is permanent magnet.Below with the first and second magnetic parts 124 and 126
It is electromagnet, as a example by the 3rd magnetic part 146 is permanent magnet, describes according to another exemplary enforcement of the present invention
The keyboard of example.
Fig. 5 illustrates the keyboard 200 according to another one exemplary embodiment of the present invention, itself and the key shown in Fig. 1
Dish 100 is essentially identical, in addition to the first magnetic part 124 and the second magnetic part 126 are all electromagnet.
Additionally, oriented first magnetic part 124 and the circuit of the second magnetic part 126 power supply can be formed on base plate 120.
The structure of here is omitted keyboard 200.
When keyboard 200 starts, can power to produce to the first magnetic part 124 and the second magnetic part 126
The raw magnetic force repelling the 3rd magnetic part 146, so that keycap 140 is positioned at initial standby position.Keyboard 200
After operation can be essentially identical with the above operation of keyboard 100.
Alternatively, keyboard 200 can also be with the method operation described referring to Fig. 6, and Fig. 6 illustrates key
Six kinds of states in the operating process of dish 200.
As shown in Figure 6, after state 1 illustrates keyboard 200 startup, keycap 140 is in initial standby position,
Such as first position, the 3rd magnetic part 146 is substantially facing to the second magnetic part 126.Now, the second magnetic
Property part 126 be powered to produce the magnetic force of supporting keycap 140, and the first magnetic part 124 is not powered,
The most do not produce magnetic force.During user key-press, need bigger by bonding force overcome the 3rd magnetic part 146 with
Repulsive magnetic force between second magnetic part 126 is to press keycap 140.
When keycap 140 starts to be pressed, as shown in state 2, X support 160 does shearing motion, makes
Obtaining end 162b drives the 3rd magnetic part 146 to slide along with base plate 120 direction that is substantially parallel, thus
3rd magnetic part 146 deviation with the second magnetic part 126 substantially relative to position.As it was previously stated, magnet
Magnetic fidle of end is relatively strong, and dies down rapidly to magnetic field, direction, both sides.So, the 3rd magnetic part 146 gradually takes off
Magnetic line of force close quarters from the second magnetic part 126.In this process, the 3rd magnetic part 146 and second
Repulsive magnetic force between magnetic part 126 is gradually reduced, and can also reduce therewith by bonding force.
It follows that as shown by state 3, keycap 140 continues down to press, until arriving the second place, example
Such as its lowest position.During the second place, the 3rd magnetic part 146 progressively disengages the second magnetic
The magneticaction scope of property part 126, enters into the position relative with the first magnetic part 124.Note,

It is thus possible to recognize that keycap 140 has been pressed against extreme lower position, and unclamp button finger, complete button
Action.
After user unclamps finger, as shown in state 4, keycap 140 is coming from the first magnetic part 124
Under the effect of magnetic repulsion, move up, thus the 3rd magnetic part 146 along return path slide, gradually from
Open the position relative with the first magnetic part 124, and enter with the second magnetic part 126 relative to position,
As shown in state 5.Final keycap 140 returns to primary importance, enters armed state, as shown in state 6.
Now, circuit stops powering to the first magnetic part 124, only continues to think that the second magnetic part 126 is powered.
For the keyboard 200 shown in Fig. 5, when shutdown, the first and second magnetic parts 124 and 126
The most no longer continue power supply.Now, under gravity, keycap 140 automatically falls off the second place.
And hence it is also possible to reduce the general thickness of keyboard 200.
Or, in another embodiment, during shutdown, can be by circuit to the first and second magnetic parts 124
A reverse current pulses is applied so that produce between they and the 3rd magnetic part 146 and attract each other with 126
