When the target condition is met, the force releasing structure 30 stops feeding back the elastic force of the spring 9 to realize the instant force releasing of the trigger; the connecting structure 40 is connected between the trigger 1 and the force relief structure 30. By the movement of the driving structure 20, the compression of the spring 9 is enabled, so that the spring 9 can provide different elastic forces; the spring force of the spring 9 is transmitted through the relief structure 30 to the connecting structure 40 and thus to the trigger 1. The prepressing of the spring 9 can be adjusted through the driving structure 20, the elasticity of the spring 9 is fed back to the trigger 1 through the force releasing structure 30 and the connecting structure 40, and different force value curves can be obtained when the trigger 1 is pressed due to the adjustable elasticity of the spring 9, so that a user can obtain richer game experience according to different game scenes; therefore, the user can not only feel through the control object on the screen but also directly feel the feedback force transmitted to the hand by the trigger 1 in the process of operating the trigger 1, and therefore, good operation hand feeling can be obtained.
After the trigger 1 is pressed, the elastic force of the spring 9 is fed back to the trigger 1 through the force releasing structure 30 and the connecting structure 40, and at the moment, the force releasing structure 30 transmits the elastic force of the spring 9 to the connecting structure 40; when the target condition is met, the force releasing structure 30 stops feeding back the elastic force of the spring 9 to the trigger 1, and the force releasing of the trigger is realized. The setting of the target condition can be set according to the requirements of the game, and can be set such that the trigger is pressed to the limit position, or the spring is compressed to a certain position, or the control module directly controls according to the game content, and the like.

Referring to fig. 3, the push rod 6 and the slide block 8 are arranged in a contact manner, so that the force interaction transmission between the push rod 6 and the slide block 8 is realized. The movement of the push rod 6 is realized by pressing or releasing the trigger 1, when the trigger 1 is pressed, the trigger 1 rotates around the trigger rotating shaft 3, and the trigger 1 pushes the push rod 6 to move towards the direction close to the slide block 8 through the connecting structure 40, so that the push rod 6 pushes the slide block 8 to move; after the trigger 1 is released, the trigger 1 rotates and resets around the trigger rotating shaft 3, and the trigger 1 pulls the push rod 6 to move away from the slide block 8 through the connecting structure 40, so that the push rod 6 resets, and the slide block 8 moves towards the direction close to the push rod under the pushing of the spring 9.

In order to position the spring push block 10, a potentiometer 15 for detecting the position of the spring push block 10 is provided on the fixed base 14, and a potentiometer circuit board 16 is provided on the potentiometer 15.
The connecting structure 40 is a connecting rod 4 and two connecting rod rotating shafts 5 positioned at two ends of the connecting rod 4, one end of the connecting rod 4 is hinged with the trigger 1, the other end of the connecting rod 4 is hinged with the force release structure 20, and the other end of the connecting rod 4 is hinged on the push rod 6.
The control method of the feedback force device of the game handle trigger controls the driving structure 20 to act and adjust the prepressing of the spring 9 according to the game scene, and the spring 9 gives the feedback force to the trigger 1 through the force releasing structure 30 and the connecting structure 40. For ease of description of the direction of movement, the direction of approach to the trigger 1 is forward and vice versa.
When the driving structure does not act without force leakage, as shown in fig. 1, 2 and 3, in the state that the trigger 1 is not pressed, the push rod guide 6-1 of the push rod 6 and the slide block guide 8-1 of the slide block 8 are positioned at the through opening 7-3 of the bracket 7, and the slide block guide 8-1 and the push rod guide 6-1. After the trigger 1 is pressed, when the trigger 1 drives the push rod 6 to slide back and forth through the connecting rod 4, the push rod inclined plane 6-2 of the push rod 6 pushes the slide block inclined plane 8-2 on the slide block 8 to move, so that the slide block 8 synchronously slides backwards along with the push rod 6, and the elastic force of the spring 9 is transmitted to the trigger 1 to obtain the pressing feedback force. When the trigger 1 is pressed to drive the sliding block 8 to move backwards, the limiting groove 8-3 of the sliding block 8 is clamped with the stopping rib position 11-1 of the clutch push button 11, so that the circumferential rotation of the sliding block 8 is limited, the sliding block 8 cannot rotate around the bracket 7, and the elastic force of the spring 9 is transmitted to the trigger 1 all the time, as shown in fig. 4-6; at this time, the spring pushing block 10 is at the initial position, the prepressing force of the spring 9 is minimum, and the operation force fed back to the trigger 1 is relatively small.
When the motor 13 is started and drives the spring push block 10 to slide forward for a certain distance, the prepressing force of the trigger spring 9 is increased, and a large operation force can be fed back to the trigger 1, which is shown in fig. 7, 8, 9 and 10.
When the trigger 1 requires significant physical relief, the clutch button 11 is moved to release the restraint on the slider 8 and the trigger 1 needs to be depressed. Moving the clutch push button 11 to release the limitation on the sliding block 8, so that the limiting groove 8-3 is staggered with the stop rib position 11-1; the push rod 6 and the slide block 8 are driven to move backwards by pressing the trigger 1. When one side of the push rod inclined plane 6-2 far away from the sliding block 8 is adjacent to one side of the sleeve inclined plane 7-2 close to the sliding block 8, due to the fact that the clutch is released and the sliding block 8 is limited by the push button 11, under the action of the elastic force of the spring 9, the sliding block guide rail 8-1 moves along the push rod inclined plane 6-2 and the sleeve inclined plane 7-2, and the sliding block 8 moves forwards while rotating; when the slide block guide rail 8-1 moves to one side of the sleeve inclined plane 7-2 far away from the slide block 8, the slide block guide rail 8-1 is stopped by the next push rod guide rail 6-1; at the moment, the force of the spring 9 acting on the sliding block 8 is transmitted to the sleeve inclined plane 7-2, namely the elastic force of the spring 9 is not transmitted to the trigger 1 any more, so that the feedback force of the trigger 1 is quickly reduced, and the experience feeling of instant force leakage is obtained. Fig. 11, 12 and 13 show the configuration when the trigger is not pressed, although the force can be released. Fig. 14, 15, and 16 show the state immediately after the trigger is pressed, i.e., immediately after the force is released. Fig. 17, 18, and 19 show the state when the force release is completed.
After the trigger 1 is released, the trigger 1 is loosened, and the trigger 1 with the push rod 6 returns to the original position under the action of the elasticity of the torsion spring 2; in the process, the push rod 6 is pulled to reset, so that the push rod guide rail 6-1 moves towards the direction far away from the sliding block 8, the push rod inclined plane 6-2 and the sleeve inclined plane 7-2 are positioned on the same inclined plane, and one side, far away from the sliding block 8, of the sleeve inclined plane 7-2 is adjacent to one side, close to the sliding block 8, of the push rod inclined plane 6-2; at the moment, the slide block guide rail 8-1 in contact with the sleeve inclined plane 7-2 can move along the sleeve inclined plane 7-2 and the push rod inclined plane 6-2 and then is stopped by the next sleeve guide rail 7-1; the push rod ramp 6-2 contacts the slider ramp 8-2 and enters the next cycle of operation. Refer to the states shown in fig. 20, 21, 22.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
