[0002] With the vigorous development of the game industry, various game controller peripherals such as operating handles, virtual reality devices, augmented reality devices, etc. are used as common tools for games to input information to objects in the game, etc., resulting in users' increasingly higher sensory requirements for game controllers. However, due to the spatial limitations of game controllers, it is difficult to add mechanical devices in the limited game controller space to transmit the real-scene feeling to the user. Therefore, the simple vibration mechanism in the existing game controller is far from meeting the game users' demand for gaming experience. There is an urgent need for a damping feedback mechanism that can improve the damping texture of the game controller and provide richer and more delicate tactile feedback, especially a damping feedback mechanism that can bring stable force transmission and damping feedback to the input device, thereby enhancing the gaming experience.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] The utility model is a damping feedback mechanism and an input device such as Figure 1 and Figure 2The input device 1 applied to the game device (not shown) includes a shell 10, a trigger key 11 adapted to be inserted into the shell 10, and a damping feedback mechanism 2 fixed in the shell 10. One end of the trigger key 11 is hingedly fixed to the shell 10, and the other end can rotate around the shell 10. When the control system (not shown) of the game device automatically recognizes that damping force feedback is required, it is necessary to press the trigger key 11, the game device automatically starts the power supply, the damping feedback mechanism 2 is started, the trigger key 11 continues to be pressed down and abuts against the damping feedback mechanism 2, the damping feedback mechanism 2 is subjected to resistance, and the trigger key 11 is subjected to force feedback, thereby achieving a strong damping effect of the input device 1 and bringing the user high-quality tactile feedback.

[0035] Damping feedback mechanism such as Figures 2 to 5 As shown, it includes a driving motor 20, a reducer 21, a transmission mechanism 22 and an angle sensor 226 which are fixed in sequence as an integral whole, and a reset mechanism 23 which is separately and spaced apart. Preferably, the reducer 21 is configured as a three-stage planetary gear (not shown) to achieve high transmission efficiency and large transmission ratio.

[0036] Transmission mechanism 22 Figures 3 to 6 As shown, it includes a gear box 220 and a driving gear 221, an intermediate gear 222, a driven gear 223, an output gear 224 and a sector gear 225 which are sequentially arranged for transmission; the gear box 220 includes a rectangular frame 2200 with a bottom wall 2201 and a cover 2210 which is engaged with the frame 2200 to form an accommodating space; an angle sensor 226 is fixed on the upper surface outside the cover 2210; the driving gear 221, the intermediate gear 222 and the driven gear 223 are arranged in the accommodating space and are arranged in parallel with the axes, and the same speed external spur gear meshing transmission; the driven gear 223 and the output gear 224 are coaxially arranged at intervals, and the spur gear of the output gear 224 is arranged at intervals. The diameter is larger than the driven gear 223, and the force transmission is realized through a simple gear transmission structure, which reduces the speed and increases the torque, thereby producing a stronger damping feeling; a mounting portion 2202 is protruding downward on one side of the long side of the frame 2200, and the fan gear 225 is arranged below the mounting portion 2202 and can slide along the mounting portion 2202, and the output gear 224 is located below the outer surface of the bottom wall 2201, and the output gear 224 and the fan gear 225 are meshed with the outer straight teeth at the bottom of the gear box 220. The fan gear 225 slides along the mounting portion 2202 through the meshing transmission of the output gear 224, thereby realizing the abutment of the sliding and retractable fan gear 225 with the trigger button 11.

[0037] The driving shaft 2210 is passed through the center of the driving gear 221, the intermediate shaft 2220 is passed through the center of the intermediate gear 222, and the output shaft 2240 is passed through the center of the driven gear 223 and the output gear 224. The driving shaft 2210, the intermediate shaft 2220 and the output shaft 2240 are parallel to each other to achieve stable force transmission and output between the driving gear 221, the intermediate gear 222, the driven gear 223 and the output gear 224. The bottom wall 2201 of the frame 2200 is respectively adapted to set the first through hole 2206, the first blind hole 2207 and the second through hole 2208 corresponding to the driving shaft 2210, the intermediate shaft 2220 and the output shaft 2240, and the cover 2210 is adapted to set the third through hole 2211 corresponding to the output shaft 2240, so as to achieve stable position limiting of the driving shaft 2210, the intermediate shaft 2220 and the output shaft 2240 by the gear box 220, and ensure stable force transmission and output. The driving shaft 2210 is connected to the output end of the reducer 21 fixed to the gear box 220 through the first through hole 2206. One end of the output shaft 2240 is extended from the third through hole 2211 of the cover body 2210, and the other end is extended from the second through hole 2208 of the bottom wall 2201. The end extended from the cover body 2210 is non-circular and penetrates the angle sensor 226, so that the angle sensor 226 can obtain the rotation angle of the output shaft 2240 and feedback it to the control system of the game device (not shown). The control system can monitor the position of the driving shaft 2210 according to the transmission ratio of the transmission mechanism 22, so as to facilitate the control system to accurately control the operation of the driving motor 20, thereby realizing a more accurate feedback output of the damping force of the trigger button 11, thereby providing the user with a better tactile feedback experience. The outer surface of the cover body 2210 is provided with a first limiting portion 2212 and a second limiting portion 2213 at intervals; the angle sensor 226 is clamped and fixed between the first limiting portion 2212 and the second limiting portion 2213 to limit the angle sensor 226, thereby ensuring that the angle sensor 226 accurately obtains the angle of the output shaft 2240.

[0038] The sector gear 225 includes an integral body 2250, a sliding portion 2251 disposed above the body 2250, and an arcuate spur rack 2252 protruding from the side of the body 2250; the length of the arcuate spur rack 2252 is greater than the length of the body 2250, so that the arcuate spur rack 2252 can abut against the trigger button 11; the mounting portion 2202 includes a third limiting portion 2203 integrally disposed with the frame 2220 and a fourth limiting portion 2204 detachably fixed to the third limiting portion 2203, the third limiting portion 2203 and the fourth limiting portion 2204 are combined to form a sliding groove 2205 adapted to the sliding portion 2251, the sliding portion 2251 slides back and forth along the sliding groove 2205 to drive the arcuate spur rack 2252 to slide back and forth, thereby realizing that the arcuate spur rack 2252 of the sector gear 225 abuts against the trigger button 11.

[0039] The transmission mechanism 22 is fixed to the inner wall of the housing 10 through the gear box 220; the reset mechanism 23 includes a torsion spring (not shown), one end of which is fixed to the inner wall of the housing 10, and the other end abuts against the inner wall of the rotating end of the trigger button 11. As the output gear 224 meshes and rotates, the arc-shaped spur rack 2252 can be extended and retracted along the sliding groove 2205 to achieve abutment and separation with the trigger button 11. When the control system automatically recognizes that the game device does not need damping force feedback, the user releases the trigger button 11 of the input device 1, and the torsion spring of the reset mechanism 23 returns the trigger button 11 to the initial position. At the same time, the drive motor 20 of the damping feedback mechanism 2 reverses to pull the gear chain back to the initial position.
