The first torsion arm 2-1 is arranged on the trigger 1 and can rotate along with the trigger 1, or the first torsion arm 2-1 is blocked on the trigger 1, when the trigger 1 is pressed, the trigger 1 pushes the first torsion arm 2-1 to rotate together, so that the torsion spring 2 is compressed; the torsion spring 2 gives a feedback force to the trigger 1 through the first torsion arm 2-1.

Referring to fig. 3, a raised platform 4-2 is arranged on the side surface of the swing rod 4, a groove 4-1 for accommodating the second torsion arm 2-2 is arranged on the platform 4-2, and the second torsion arm 2-2 is positioned in the groove 4-1; when the swing rod 4 rotates, the groove wall of the groove 4-1 transmits the pushing force to the second torsion arm 2-2, so that the second torsion arm 2-2 and the swing rod 4 rotate together to realize the adjustment of the pre-pressing of the torsion spring 2. The raised platform 4-2 and the groove 4-1 are arranged, so that the torsion spring 2 is favorably and stably positioned in the groove 4-1.
The torsion spring 2 and the swing rod 4 are coaxially arranged and rotate around the first rotating shaft 3. Two first supporting plates 12-3 hinged with the swing rod 4 are arranged on the fixed support 12, and a release structure 12-1 used for releasing the second torsion arm 2-2 from the groove 4-1 and a force-releasing limiting structure 12-2 used for releasing the second torsion arm 2-2 are arranged on the first supporting plates 12-3. The torsion spring 2 rotates within a certain angle range, and when the torsion spring 2 rotates to the maximum angle, the loosening structure 12-1 loosens the second torsion arm 2-2 and the groove 4-1, so that the effect of instant force release is achieved. Specifically, when the swing rod 4 reaches the maximum position, the release structure 12-1 pushes the release structure 12-1 in a direction away from the swing rod 4, and pushes the release structure 12-1 out of the groove 4-1, so that the second torsion arm 2-2 is released from the groove 4-1. After the second torsion arm 2-2 is separated from the groove 4-1, the second torsion arm 2-2 moves towards the force-releasing limiting structure 12-1 along the end surface of the platform 4 and is stopped by the force-releasing limiting structure 12-1; that is, when the swing rod 4 rotates to the maximum angle, the second torsion arm 2-2 is loosened from the groove 4-1 and moves to the force-releasing limiting structure 12-1 to be stopped.
Specifically, referring to fig. 28, the force-releasing limiting structure 12-1 is a protrusion disposed on the inner side of the first supporting plate 12-3; the loosening structure 12-2 is provided with a loosening rod 12-2-1 extending towards the direction of the swing rod 4 and a claw part 12-2-2 extending along the end part of the loosening rod 12-2-1 in a bending way, and a loosening inclined surface 12-2-3 used for pushing the second torsion arm 2-2 to be separated from the groove 4-1 is arranged on the claw part 12-2-2. The loosening inclined plane 12-2-3 inclines towards the direction far away from the swing rod 4 in the rotating direction of the swing rod 4 increasing the torque of the torsion spring 2, namely when the swing angle of the swing rod 4 is increased, the torsion spring 2 is compressed to increase the torque, and after the second torsion arm 2-2 moves to the loosening structure 12-2, the swing rod 4 drives the second torsion arm 2-2 to move along the loosening inclined plane 12-2-3 to push the second torsion arm 2-2 to move towards the direction far away from the swing rod 4, so that the second torsion arm 2-2 is separated from the groove 4-1; the torsion spring 2 is compressed to give the second torsion arm 2-2 a restoring torque so that the second torsion arm 2-2 is rapidly moved along the side end surface of the platform 4-2 toward the initial position. When the second torsion arm 2-2 moves to the force-releasing limiting structure 12-1, the second torsion arm 2-2 is stopped and is at the initial position. At this time, the torsion spring 2 is instantaneously emptied, so that the feedback force transmitted from the torsion spring 2 to the trigger 1 through the first torsion arm 2-1 is instantaneously discharged.
A blocking edge 4-3 extending along one end of the groove 4-1 far away from the force-releasing limiting structure 12-1 is arranged on the platform 4-2, and the blocking edge 4-3 is used for resetting the second torsion arm 2-2 into the groove 4-2 after the second torsion arm 2-2 is separated from the groove 4-2. After the second torsion arm 2-2 is separated from the groove 4-1, the second torsion arm 2-2 is blocked by the force-releasing limiting structure 12-1; then the swing rod 4 is driven to reset and rotate, the second torsion arm 2-2 moves relatively along the side end face of the platform 4-2, when the baffle edge 4-3 moves to the second torsion arm 2-2, the second torsion arm 2-2 slides into the groove 4-2, and the second torsion arm 2-2 has a force towards the direction close to the swing rod 4.
The driving structure comprises a gear set 20 meshed with the swing rod 4, a worm 10 meshed with the gear set 20 and a motor 11 connected with the worm 10, after the motor 11 is started, the worm 10 is driven to rotate, the worm 10 drives the gear set 20 to rotate, the gear set 20 transmits torque to the swing rod 4, and the swing rod 4 is driven to rotate in the direction of increasing the torque of the torsion spring 2 or to reversely reset and move. The gear set 20 is provided with a large transmission gear 5 meshed with the swing rod 4, a small transmission gear 7 meshed with the large transmission gear 5, and a worm wheel 8 coaxially and fixedly arranged with the small transmission gear 7, and the worm wheel 8 is meshed with the worm 10. The turbine 8 and the small transmission gear 7 are sleeved on the turbine rotating shaft 9, and a third supporting plate 12-4 for supporting the turbine rotating shaft 9 is arranged on the upper side of the fixed support 12; the motor 11 and the worm 10 are located at the lower side of the fixed support 12, and in order to realize the meshing between the worm wheel 8 and the worm 10, a through hole 12-5 for the worm wheel 8 to extend downwards is formed in the fixed support 12.
The first supporting plate 12-3 extends towards the direction close to the trigger 1 and protrudes out of the fixed bracket 12, and the trigger 1 is hinged on the first supporting plate 12-3 through the first rotating shaft 3. The worm wheel 8 and the worm 10 have self-locking function, so that the oscillating bar 4 can be stopped at different positions, and different operating forces are fed back to the trigger 1.
The control method of the feedback force device comprises the following steps: according to a game scene, the driving structure is controlled to drive the swing rod 4 to rotate, and the pre-pressure of the torsion spring 2 is adjusted, so that the required feedback force provided by the torsion spring 2 is obtained when the trigger 1 is pressed.
4-6, when the torsion spring 2 does not need to be pre-pressed, the swing rod 4 is located at the initial position, the trigger 1 is pressed to enable the first torsion arm 2-1 to rotate along with the trigger 1, and the second torsion arm 2-2 is in a static state on the swing rod 4; the torsion spring 2 is compressed, the torsion spring 2 gives feedback force to the trigger 1 through the first torsion arm 2-1, the torsion spring 2 also gives reverse torque to the swing rod 4 through the second torsion arm 2-2, and the torque received by the trigger 1 is equal to the torque received by the swing rod 4 in magnitude and opposite in direction.
As shown in fig. 7-9, when the torsion spring 2 needs to be pre-pressed, the swing rod 4 is driven to rotate by different angles according to the pre-pressing size, if the feedback force required by the trigger 1 is large, the rotation angle of the swing rod 4 is large, and if the feedback force required by the trigger 1 is small, the rotation angle of the swing rod 4 is small. Specifically, a motor 11 is started, a worm 10 drives a turbine 8 to rotate, and further drives a small transmission gear 7 which is coaxial with the turbine 8, the small transmission gear 7 is meshed with a large transmission gear 5, the large transmission gear 5 is meshed with a swing rod 4, torque is transmitted to the swing rod 4, the swing rod 4 is driven to rotate to a required angle, a torsion spring 2 is compressed, and the torsion spring 2 gives a prepressing feedback force to a trigger 1 through a first torsion arm 2-1; after pressing the trigger 1, the torsion spring 2 is further compressed and the pressing of the trigger 1 gives the trigger 1 the required feedback force, as shown in fig. 7-9.
Of course, after the trigger 1 is pressed, it is certainly necessary to adjust the rotation angle of the swing lever 4 at any time so that the feedback force given to the trigger 1 by pressing the trigger 1 is adjusted.
As shown in fig. 10-13, when the trigger 1 needs to instantaneously release force for body sensing, the trigger 1 is pressed, the driving structure drives the swing rod 4 to rotate, and the second torsion arm 2-2 with the torsion spring 2 rotates together, when the swing angle of the swing rod 4 is increased, the torsion spring 2 is compressed to increase the torque, and after the second torsion arm 2-2 moves to the release structure 12-2, the swing rod 4 drives the second torsion arm 2-2 to move along the release inclined plane 12-2-3, so that the second torsion arm 2-2 is pushed to move in a direction away from the swing rod 4, and the second torsion arm 2-2 is released from the groove 4-1; at this time, the elastic pressure of the torsion spring 2 is released, so that the feedback force transmitted from the torsion spring 2 to the trigger 1 through the first torsion arm 2-1 is instantaneously released. As shown in fig. 14 to 17, the torsion spring 2 releases the elastic pressure by the rotation of the second torsion arm 2-2, so that the second torsion arm 2-2 is rapidly moved toward the initial position along the side end surface of the platform 4-2. When the second torsion arm 2-2 moves to the force-releasing limiting structure 12-1, the second torsion arm 2-2 is stopped and is at the initial position.
21-24, after the torsion spring 2 is relieved of force, the first torsion arm 2-1 of the torsion spring 2 pushes the trigger 1 back to the home position by releasing the pressing trigger 1; during the process, the motor 11 drives the swing rod 4 to reset, the second torsion arm 2-2 moves relatively along the side end face of the platform 4-2, when the baffle edge 4-3 moves to the second torsion arm 2-2, the second torsion arm 2-2 slides into the groove 4-2, the second torsion arm 2-2 has a force towards the direction close to the swing rod 4, and the second torsion arm 2-2 can rotate synchronously with the swing rod 4.
