The magnetic keys, the key control device and the keyboard of the embodiments of the present disclosure are applied to send a trigger signal to the control unit through a trigger module. After receiving the trigger signal, the control unit controls the current direction of the electromagnetic component in the key according to the mode selected by the user. The size and duration are used to change the direction and size of the magnetic field in the keys to produce a keyboard with a sense of passage.

Referring to FIG. 1, in one embodiment, the present disclosure provides a magnetic key, including a movable part 40, a magnet part 10, an electromagnetic part 20 and an elastic part 30.

The movable part 40 includes a central shaft body 410, a key cap 420 arranged at one end of the central shaft body 410, and a stop 430 arranged on the central shaft body 410 at a preset distance from the key cap 420; the magnet part 10 is movably arranged on the key cap 420 And the stop block 430; the elastic member 30 is sleeved on the central shaft body 410 and is located below the stop block 430.

When the acting direction of the magnetic field between the magnet part 10 and the electromagnetic part 20 changes, the magnet part 10 drives the movable part 40 to move in the vertical direction between the stopper 430 and the key cap 420.

The magnet component 10 is an ordinary magnet, and the elastic component 30 can be, but is not limited to, a return spring component. The movable part 40 and the elastic part 30 penetrate into the electromagnetic part 20.

For example, a trigger module is provided below the electromagnetic component 20, configured to detect whether the movable component 40 is pressed. For example, when the movable part 40 is pressed, the trigger module detects that the movable part 40 is pressed, the trigger module will send a trigger signal to the drive control module, the drive control module includes a control unit and at least one connected current drive circuit, and The electromagnetic component 20 is connected to a corresponding current drive circuit. Optionally, after receiving the trigger signal, the control unit sends a magnetic attraction signal to the current drive circuit. The magnetic attraction signal is, for example, a positive electrical signal, so that the current drive circuit positively energizes the connected electromagnetic component 20, thereby The magnetic field acting direction between the magnet component 10 and the electromagnetic component 20 is changed to generate a magnetic attraction force. At this time, under the action of the magnetic attraction force of the electromagnetic component 20, the magnet component 10 generates a pulling force on the movable component 40 through the stopper 430, so that the movable component 40 moves downward in the vertical direction. This pulling force can be instantaneous or can be maintained. A certain period of time. When the movable part 40 is released and lifted, the trigger module cannot detect the movable part 40, so that the control unit cannot receive the trigger signal, and the control unit sends a repulsive force signal to the current drive circuit. The signal causes the current drive circuit to reversely energize the connected electromagnetic component 20, thereby changing the direction of the magnetic field between the magnet component 10 and the electromagnetic component 20 to generate repulsive force. At this time, under the repulsive force of the electromagnetic part 20, the magnet part 10 generates a thrust on the movable part through the key cap 420, so that the movable part 40 moves upward in the vertical direction through the electromagnetic part 20 and the elastic part 30. This thrust can be instantaneous or instantaneous. It can be maintained for a certain period of time. At this time, the elastic member 30 restores and maintains the movable member 40 in the original position after the movable member 40 is pushed upward.

For another example, when the movable component 40 is pressed, the trigger module will send a trigger signal to the control unit. After receiving the trigger signal, the control unit sends a repulsive force signal to the current drive circuit, so that the current drive circuit reverses the direction of the connected electromagnetic component 20 Electricity is applied to change the direction of the magnetic field between the magnet component 10 and the electromagnetic component 20 to generate repulsive force. At this time, under the repulsive force of the electromagnetic component 20, the magnet component 10 generates a thrust on the movable component through the key cap 420. After this thrust lasts for a short time, the control unit sends a magnetic attraction signal to the current drive circuit, thereby changing the magnet component 10 and the electromagnetic The direction of the magnetic field between the components 20 generates magnetic attraction. At this time, under the action of the magnetic attraction force of the electromagnetic component 20, the magnet component 10 generates a pulling force on the movable component 40 through the stopper 430, so that the movable component 40 moves downward in the vertical direction.

In the magnetic key according to the embodiment of the present disclosure, the magnet part 10 is not fixed on the movable part 40, and the key cap 420 functions as a stopper, so that the stopper 430 cooperates with the stopper 430 to limit the movement range of the magnet part 10. In this way, under the action of a magnetic field, the magnet part 10 can move flexibly between the stopper 430 and the button cap 420, and is not restricted by the movable part 40, so that it can transmit the corresponding pulling force or thrust to it by moving up and down after receiving the magnetic attraction or repulsion. Movable parts 40. Therefore, the user can feel light when pressing the magnetic key of the embodiment of the present disclosure.

The magnetic key of the present disclosure includes a movable part 40, a magnet part 10, an electromagnetic part 20 and an elastic part 30. The elastic member 30 has a reset function, which can ensure that the key can be restored to the original position and used normally. When the acting direction of the magnetic field between the magnet part 10 and the electromagnetic part 20 changes, since the magnet part 10 is movably arranged between the key cap 420 of the central shaft body 410 and the stopper 430, the magnet part 10 can be exposed to the electromagnetic part. At the time of the magnetic attraction force of 20, the movable part 40 is pushed down by the stopper 430, or the movable part 40 is pushed up by the button cap 420 when receiving repulsive force, so that the movable part 40 moves in the vertical direction to achieve the corresponding Sense of paragraph. In the embodiment of the present disclosure, the key cap 420 in the key can be used in conjunction with the stopper 430 provided on the central shaft body 410, and the magnet part 10, the electromagnetic part 20, and the elastic part 30 can work together to make the movable part 40 stand upright.

At the same time, the magnet part 10 can be made to fall on the stopper 430 higher than the top surface of the electromagnetic part 20 when it naturally falls, which helps to move when the magnetic field between the magnet part 10 and the electromagnetic part 20 changes in the magnetic attraction force. The component 40 has enough space to move down to achieve a preset sense of paragraph. Optionally, the baffle 50a of the hollow base 50 is provided with a first through hole 60, which allows the movable part 40 to have enough space to move down to achieve a preset sense of passage, and is convenient for triggering the setting under the hollow base 50 The trigger module.

When the drive control module receives the light receiving unit 90 when the current becomes smaller, it is confirmed that the trigger signal of the trigger module is received, so that the magnetic attraction signal is output to the electromagnetic component 20, and the magnetic field acting direction between the electromagnetic component 20 and the magnet component 10 is changed so that the electromagnetic component 20 produces magnetic attraction. When the movable part 40 is released and lifted, the central axis body 410 of the movable part 40 is retracted through the first through hole 60, and the blocking between the light emitting unit 80 and the light receiving unit 90 is released, and the drive control module receives the light When the current of the receiving unit 90 returns to the specified current value, it is confirmed that no trigger signal is received.
