step S11: and acquiring a preset key mode, wherein the key mode comprises a common mode or an enhanced mode.
In the embodiment of the invention, after the keyboard is started, the keyboard can acquire a preset key mode and operate the keyboard in the preset key mode, specifically, the key mode comprises a common mode and an enhancement mode, the common mode is a mode for completing the whole key work through an elastic piece of the key, the enhancement mode is a mode for generating a force in the same direction or a force in the opposite direction of the elastic piece through controlling a coil, so that the feedback of the key is enhanced, and the coil is an electrified coil which can generate magnetic force after being electrified. Specifically, the key feedback comprises key repulsion force, key section falling feeling and key resilience force, wherein the key repulsion force increases the resistance of the key when the key is pressed, the key section falling feeling reduces the resistance of the key when the key is pressed at a preset point of the stroke, and the key resilience force increases the key elasticity when the key is rebounded at the preset point of the stroke. The combination or enhancement adjustment of the key repulsion, the key section falling feeling and the key resilience can be realized by a control coil, and the detailed description refers to the following description.
In the embodiment of the present invention, for the enhanced mode, the user may further set one, two, or all of the key repulsion, the key segment falling feeling, and the key rebound force in the enhanced mode, and adjust the intensities of the key repulsion, the key segment falling feeling, and the key rebound force, which is not limited herein. Specifically, an application program may be provided in the keyboard, and the application program is used to perform the adjustment of the enhancement mode and generate a corresponding control process of the coil, which is not limited herein.
Fig. 2 is a schematic mechanism diagram of a key provided in embodiment 1 of the present invention, wherein a key cap of the key 100 may be provided with a magnet 150, and a bottom of the key 100 may be provided with the coil 140 and the stroke sensor 110. The stroke sensor 110 is connected to a controller 120 of the keypad, and the controller 120 is connected to the driving module 130 to control the driving module 130 to transmit a preset voltage or current to the coil 140.
Step S12: when the preset key mode is the enhanced mode, the transmission of the current in the first direction and/or the current in the second direction to the coil is controlled after the key stroke acquired in real time reaches the preset stroke, so that the coil and the magnet generate corresponding repulsion and/or attraction, and the key feedback is enhanced.
In the embodiment of the present invention, as shown in fig. 2, the stroke of the key can be obtained in real time through the stroke sensor, the stroke sensor can be arranged inside the key, specifically, the stroke sensor can be a hall sensor, the hall sensor is arranged in a bottom plate of the key, that is, inside the key, correspondingly, a magnet can be arranged on a keycap of the key, and the hall sensor is used for sensing the magnitude of the magnetic flux of the magnet, so that the key stroke can be obtained in real time according to the magnitude of the magnetic flux. The travel sensor may also be arranged outside the key, and specifically may be a light sensor, and the light sensor may include a photosensitive sensor or an infrared sensor, i.e. a PT light-to-tube sensor or an IR light-to-tube sensor. The stroke sensor may also be a digital sensor, which is not limited herein.
In the embodiment of the invention, after the real-time information of the travel sensor is received, the real-time analysis of the key travel is carried out according to the information of the travel sensor, and the corresponding current or voltage is controlled to be transmitted to the coil when the key travel reaches the preset travel, so that the key feedback is enhanced. For example, a driving module may be disposed in the keyboard, and when it is detected that the key stroke reaches a preset stroke, a driving command may be sent to the driving module, so that the driving module transmits a corresponding current or voltage to the coil, so that the coil and the magnet generate an attractive force or a repulsive force, thereby generating key feedback, or enhancing key feedback.
In the embodiment of the invention, the stroke of the key comprises a pressing stroke and a rebounding stroke; the pressing stroke comprises a key conduction front stroke and a key conduction rear stroke; the rebound stroke comprises a key release front stroke and a key release rear stroke; the key conduction rear stroke comprises a key first repulsion force enhancing stroke and/or a key suction force enhancing stroke; and/or the stroke after the key is released comprises a key second repulsive force enhancing stroke. The pressing stroke is the stroke of pressing the key by the user until the key contacts the keyboard bottom plate. The rebound stroke is a stroke that the key returns to the initial state from a state of contacting the bottom plate after the user releases the pressed key.
The key is provided with a conduction point, when a user presses the key to the conduction point, the key can be conducted, namely the pressing stroke can be divided into a key conduction front stroke and a key conduction rear stroke, and in the key conduction rear stroke, a key first repulsion force enhancing stroke or a key suction force enhancing stroke can be added, or a key first repulsion force enhancing stroke and a key suction force enhancing stroke are added in sequence. And the first direction current is controlled to be transmitted to the coil in the first repulsion force enhancing stroke of the key, so that the coil and the magnet generate repulsion force, and the key repulsion force is enhanced. And in the key suction force enhancing stroke, the control unit transmits a second direction current to the coil so as to enable the coil and the magnet to generate suction force, thereby generating or enhancing paragraph feeling.
In the process of the return stroke of the key, the same position of the conduction point of the key can be a release point, namely the rebound stroke can be divided into a key release front stroke and a key release rear stroke. And a first repulsion force enhancing stroke of the key can be increased in the stroke after the key is released, and the transmission of first-direction current to the coil is controlled in a second repulsion force enhancing stroke of the key, so that the coil and the magnet generate repulsion force, thereby enhancing the return elasticity of the key and increasing the rebound speed.
In the embodiment of the invention, by increasing the stroke and controlling and transmitting the current in the corresponding direction to the coil in the corresponding stroke, the adjustment of the key repulsion force, the key section falling feeling and the key resilience force can be realized, and at least one key feedback can be selectively realized, so that a user can adjust the key repulsion force, the key section falling feeling and the key resilience force as required, and the user experience degree is improved.
In the embodiment of the present invention, the process of determining whether the stroke reaches the preset stroke may be implemented by using an algorithm or an application program, for example, an application program may be set in the keyboard, and the application program acquires the real-time stroke detected by the stroke sensor, determines whether the stroke reaches the preset stroke, and generates a corresponding instruction to control the current transmitted to the coil after the stroke reaches the preset stroke.
Fig. 3 is a flowchart of another key control method provided in embodiment 1 of the present invention, further including the following steps:
step S13: and when the preset key mode is the common mode, controlling the coil not to be electrified when the preset stroke is reached.
In the embodiment of the invention, if the preset key mode is the common mode, the coil is not electrified when the preset stroke is reached, namely, the generation of key feedback or the enhancement of the key feedback is not carried out. The method can be applied to common keys, the coil and the magnet are added in the common keys, and various combined key feedbacks can be generated by controlling the coil, wherein the key feedbacks comprise at least one of key repulsion, key section falling feeling and key elasticity. The mechanical keyboard can be applied to a mechanical keyboard, and at least one key feedback of original key repulsion, key section falling feeling and key elasticity can be enhanced by newly adding a coil and a magnet and controlling the coil, and the method is not limited here. The keyboard may be provided with an application program for receiving an instruction of a user to switch between a normal mode and an enhanced mode, which is not limited herein.
Example 2

In fig. 4, point a is an initial stroke point of the key, point B is a conduction point of the key, point C is a peak point of the key force, i.e., a peak point of the repulsive force generated by the coil, point D is a valley point of the key force, i.e., a segment where the coil generates the suction force and the spring are superposed, point E is a release point of the key, and point F is a release point of the coil after the return elastic force is generated. The point A to the point B represent an initial state before the key is conducted, the point B to the point C represent a first repulsion force enhancing stroke of the key, namely a state that the key reaches a key force peak value after being conducted, the point C to the point D represent a suction force enhancing stroke of the key, namely a state that the key performs paragraph feedback, the point D returns to the point E to represent a state that the key performs return stroke only through spring force or through superposition of the spring force and the key suction force, and the point E to the point F represent a second repulsion force enhancing stroke of the key, namely a state that a suction force feedback return stroke is added. That is, the states from point B to point C, from point C to point D, and from point E to point F may be implemented by the above-mentioned stroke detection and coil, so as to implement the feedback of the key, and the feedback implemented by each state may be implemented individually or in combination, so that the user may select the required key feedback by himself.
In the embodiment of the invention, in order to achieve the purpose of saving power, the coil can be controlled not to be electrified in the AB section stroke and the initial state before the key is conducted before the AB section stroke. And can also control the electric current in the coil in the DE section to reduce the button power, so that the user has good button to experience under the condition of holding the button for a long time, and can also control not to supply power to the coil in the DE section, thereby further accomplishing the effect of power saving. And the current magnitude, direction and duration of the coil in each section of stroke can be regulated and controlled, so that a user can face various keyboard use scenes according to requirements.

Step S52: and when the preset key mode is the enhanced mode, controlling to transmit a first-direction current to the coil after the pressing stroke reaches the key first repulsion enhanced stroke, so that the coil and the magnet enhance the key repulsion during the key first repulsion enhanced stroke.
In the embodiment of the invention, if the enhanced key repulsion force is set in the enhanced mode, after the pressing stroke is detected to reach the enhanced stroke of the first key repulsion force, namely after the pressing stroke passes through the conducting point of the key, the current in the first direction can be controlled and transmitted to the coil, so that the coil and the magnet generate the repulsion force, and the direction of the repulsion force is consistent with the elastic force direction of the key elastic part, therefore, the resistance of the key is increased, namely the key repulsion force is enhanced in the enhanced stroke of the first key repulsion force.

step S53: and after the pressing stroke reaches the key suction force enhancing stroke, controlling to transmit a second direction current to the coil, so that the coil and the magnet generate a suction force enhancing key segment falling feeling during the key suction force enhancing stroke.
In the embodiment of the invention, if the enhanced key segment sense is set in the enhanced mode, after the detection of the enhanced stroke of the key attraction, the current in the second direction can be controlled to be transmitted to the coil, so that the coil and the magnet generate the attraction, and the direction of the attraction is opposite to the elastic direction of the key elastic piece, so that the resistance of the key is reduced, namely the key generates the segment sense during the enhanced stroke of the key attraction, or the segment sense of the key is enhanced.

step S54: and after the rebound stroke reaches the key second repulsion force enhancing stroke, controlling to transmit a first-direction current to the coil, so that the coil and the magnet generate repulsion force enhancing key rebound speed during the key second repulsion force enhancing stroke.
In the embodiment of the invention, if the enhanced key rebound speed is set in the enhanced mode, after the enhanced stroke of the second repulsive force of the key is detected, the current in the first direction can be controlled and transmitted to the coil, so that the coil and the magnet generate the repulsive force, and the direction of the repulsive force is consistent with the elastic direction of the key elastic piece, thereby accelerating the key rebound speed.
In the embodiment of the present invention, at least one of the steps S52, S53, and S54 may be selectively executed in the enhanced mode of the keyboard according to the setting of the user, so that the user can freely combine the keys as required, and adjust the key repulsion, the key segment falling feeling, and the key rebound speed.
In the embodiment of the invention, the coil is electrified only in the first repulsion force enhancing stroke and/or the suction force enhancing stroke and/or the second repulsion force enhancing stroke of the key. That is, in the key stroke other than the above-mentioned stroke, the coil is not energized, thereby achieving the function of saving electric power.
