Description

Technical Field

[0001] The utility model relates to the technical field of game handles and discloses a force feedback mechanism and an input device. Background Art

[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 users. 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 force feedback mechanism and input device that can improve the damping texture of the game controller, provide richer and more delicate tactile feedback, and thus enhance the gaming experience. Utility Model Content

[0003] The purpose of the utility model is to provide a force feedback mechanism and an input device, aiming to solve the problem of poor user tactile feedback caused by poor damping texture of the force feedback mechanism of the existing game input device. The specific technical solution is as follows:

[0004] A force feedback mechanism comprises a driving motor, a reducer, a transmission mechanism and a reset mechanism in sequence, wherein the transmission mechanism comprises a gear box and a driving gear, an intermediate gear, a driven gear, an output gear and a fan gear which are arranged in sequence; the driving gear, the intermediate gear and the driven gear are arranged in parallel with each other in a same-speed external spur meshing transmission, the driven gear and the output gear are arranged coaxially and spaced apart, the output gear meshes with the external spur teeth of the fan gear, the driving gear, the intermediate gear and the driven gear are located in the gear box, the output gear is fixed under the gear box, the fan gear is fixed under the gear box and can slide along the gear box; the reset mechanism comprises a torsion spring.

[0005] Preferably, the reducer is configured as a three-stage planetary gear.

[0006] Preferably, the output gear has a diameter greater than that of the driven gear.

[0007] The utility model also provides an input device, comprising a shell and a trigger key adapted to penetrate the shell, and also comprising the force feedback mechanism.

[0008] Preferably, the force feedback mechanism is fixed in the housing.

[0009] Preferably, the reset mechanism and the transmission mechanism are separately and spaced apart from each other; the transmission mechanism is fixed in the housing through the gear box.

[0010] Preferably, one end of the trigger button is hingedly fixed to the shell, and the other end can rotate around the shell.

[0011] Preferably, one end of the torsion spring is fixed to the inner wall of the shell, and the other end of the torsion spring abuts against the inner wall of the trigger button.

[0012] Preferably, the sector gear can abut against the trigger button.

[0013] Compared with the prior art, the force feedback mechanism used in the input device of the utility model increases the torque by decelerating and realizes the force transmission through three-axis gears, producing a stronger damping texture, providing users with richer and more delicate tactile feedback, thereby enhancing the gaming experience.

[0024] 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.

[0025] The utility model provides a force feedback mechanism and an input device as follows Figure 1 and Figure 2 The 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 force 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 feedback force is needed, it is necessary to press the trigger key 11, the game device automatically starts the power supply, the force feedback mechanism 2 is started, the trigger key 11 continues to be pressed down and abuts against the force feedback mechanism 2, the force 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.

[0026] Force feedback mechanism such as Figures 2 to 5As shown, it includes a driving motor 20, a reducer 21 and a transmission mechanism 22 that are mutually transmitted, and a reset mechanism 23 that is spaced apart from the transmission mechanism 22; preferably, the reducer 21 is set as a three-stage planetary gear 210 so that the transmission efficiency is high and the transmission ratio is large; the transmission mechanism 22 includes a gear box 220 and a driving gear 221, an intermediate gear 222, a driven gear 223, an output gear 224 and a fan gear 225 that are sequentially transmitted, wherein the driving gear 221, the intermediate gear 222 and the driven gear 223 are located in the gear box 220 and are parallel to the axes and are in a same-speed external spur gear meshing transmission, and the driven gear 223 and the output gear 224 are coaxially spaced apart The diameter of the output gear 224 is larger than that of the driven gear 223. Through a simple gear transmission structure, the force transmission is realized, the torque is increased by reducing speed, and a stronger damping feeling is generated; the output gear 224 and the fan gear 225 are fixed on the lower surface outside the gear box 220 to realize the outer spur meshing of the output gear 224 and the fan gear 225, and the fan gear 225 can slide along the gear box 220 to realize the abutment of the fan gear 225 and the trigger key 11; the transmission mechanism 22 is fixed on 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 the torsion spring is fixed on the inner wall of the housing 10, and the other end abuts against the inner wall of the rotating end of the trigger key 11. When the control system of the game device automatically recognizes that the game device does not need feedback force, the user releases the trigger key 11 of the input device 1, and the torsion spring of the reset mechanism 23 returns the trigger key 11 to the initial position. At the same time, the driving motor 20 of the force feedback mechanism 2 reverses to pull the gear chain back to the initial position.
