In the actual use process, the user presses the key body 10 to drive the sliding piece 21 to move, so that the sliding piece 22 on the sliding piece 21 moves relative to the transmission piece 23, and in the process, the transmission piece 23 rotates. The sensing assembly 40 detects the movement of the slider 22 and feeds back a detection signal (detection value) to the driving assembly 30. The driving component 30 controls the transmission member 23 to rotate according to the detection value fed back by the sensing component 40, and the rotation direction can be the same as or opposite to the rotation direction of the transmission member 23 caused by pushing the sliding block 22 by the key body 10, so that the sliding member 21 performs bidirectional force transmission, and force feedback of the key body 10 is realized.

The sliding block 22 is driven to move back and forth by the rotation of the screw rod in two directions, so that the sliding piece 21 performs bidirectional force transmission, and force feedback of the key body 10 is realized.

The lead angle is understood to mean the angle between the tangent of the spiral and a plane perpendicular to the thread axis on a pitch diameter cylinder or pitch diameter cone. The equivalent friction angle is understood to mean that the thread is formed by winding a bevel on a cylinder, the thread applying the bevel principle, in a bevel slide model, when the bevel is tilted to an angle, the friction force of the slide at this time is exactly equal to the component of gravity along the bevel. At this time, the inclined plane is just in a stress balance state, and the inclined plane inclination angle at this time is called an equivalent friction angle.

The gear assembly 32 may be multi-stage or otherwise, and will not be described in detail in this disclosure.
In the present invention, when a user presses the key body 10 of the electronic device, the key body 10 drives the contacted elastic body 24, the sliding member 21 and the sliding member 22 to move synchronously, so as to drive the transmission member 23 to rotate. The driving member 23 drives the gears inside the gear case 321 to rotate, and finally drives the driving shaft 311 to rotate. If the drive motor 31 is energized at this time, the drive motor 31 will lock up to provide a damping sensation to the press.
In the present invention, the driving of the driving motor 31 may also affect the key body 10 in reverse, and the motion transmission order is the motor shaft (driving shaft 311), the gear case 321, the transmission member 23, the slider 22, the slider 21, the elastic body 24, and the key body 10. By adjusting parameters such as forward and reverse rotation, voltage (locked rotor torque), and acting time of the drive motor 31, effects of force feedback such as damping, force release, vibration, and rebound can be achieved.
The damping effect is achieved by transmitting the pressing force to the driving shaft 311 through the sliding member 21, the sliding block 22, the transmission member 23 and the gear transmission assembly 32 when the user presses the key body 10, the pressing force causes the driving motor 31 to stop rotating, and the voltage of the driving motor 31 is adjusted to change the stop rotating torque of the driving motor 31, so that different pressing damping effects are achieved.
When the user presses the trigger button, the driving shaft 311 of the driving motor 31 rotates forward and backward rapidly, so that the vibration can be transmitted to the button body 10 through the gear transmission assembly 32, the transmission member 23, the sliding block 22 and the sliding member 21, and the user gets feedback of the vibration. After the key body 10 is pressed to generate damping, the output torque of the driving motor 31 is instantaneously reduced, the feedback force is immediately reduced, and the experience effect of force leakage is generated.
According to the invention, the rotation ratio and output force of the key module can be influenced by setting parameters such as the lead of the screw (the transmission piece 23), the reduction ratio of the gear transmission assembly 32 and the like, so that force feedback responses with different precision and strength can be realized.
