[0017] The specific embodiments of the utility model are described in detail below in conjunction with the drawings.

[0018] The utility model proposes a kind of gamepad, such as Figure 1The game handle is a game handle with force feedback and tactile feedback, which is suitable for shooting games. The game handle comprises a shell A1, a trigger A2 exposed from the shell, a force feedback actuator A3, a control mainboard A4 and a vibrator A5 for providing tactile feedback effect which are assembled in the shell. The shell A1 adopts ergonomic design, is comfortable to hold and convenient to operate, the main body adopts engineering plastic and has good strength and wear resistance; the corrugated anti-skid lines A6 are designed on the grip part, and a skin-like coating or anti-skid rubber is coated on the outside, so that the comfort of holding is improved. The trigger A2 adopts high-strength nylon material and has good toughness and wear resistance, the trigger is connected to the pivot point on the shell through a pin and connected to the force feedback actuator A3 through a connecting rod mechanism, and the connecting rod mechanism can be a gear-rack system or a push rod structure. The control mainboard A4 is a PCB circuit board, on which a main control unit, a lithium battery, a charge-discharge management circuit, a vibration motor driving circuit, a force feedback actuator control circuit and a wireless communication unit are integrated, the force feedback actuator A3 and the vibrator A5 are connected through a control cable, and a game host is connected through a wireless unit, Figure 2 The vibrator A5 is a mechanical vibration motor with an eccentric mass or a MEMS linear vibration motor.

[0019] The force feedback actuator A3 is an electromagnetic linear actuator, and its working principle is based on electromagnetic induction principle. The energized coil is subjected to force in the magnetic field, so as to drive the connected parts to move linearly. Figure 3 The function component logic block diagram is shown, which comprises:

[0020] The shell protects the internal components and provides assembly support structure and fixing screw holes;

[0021] The electromagnetic coil is wound on a hollow skeleton composed of a high-permeability magnetic core, and the magnetic core is silicon steel, which generates a controllable magnetic field after being energized;

[0022] The permanent magnet mover is fixed on the linear guide mechanism inside the coil and interacts with the coil magnetic field to generate driving force; the mover can freely move on the guide mechanism and is connected to the trigger through the connecting rod mechanism;

[0023] The position sensor adopts an integrated Hall sensor or an optical encoder, which detects the displacement of the mover in real time and feeds back to the control circuit;

[0024] The elastic reset element is a torsion spring or a spring sheet, which provides basic reset rebound force, so that the mover quickly returns to the initial position after power-off, and cooperates with the electromagnetic force to realize composite feedback effect and optimize the smoothness of the touch feeling.

[0025] The electromagnetic coil is fixed inside the shell, the linear guide mechanism is a linear guide rail, and is fixedly installed inside the electromagnetic coil, so that the mover can move bidirectionally along the central axis of the electromagnetic coil under the action of electromagnetic force; and the position sensor is installed on the side of the permanent magnet mover, and can feed back the position information of the moving iron core in real time, so that accurate control is realized.

[0026] When current flows through the coil, a magnetic field is generated, which interacts with the magnetic field of the permanent magnet to produce an attractive or repulsive force, causing the mover to move linearly and transmitting the force to the trigger through the transmission mechanism; by changing the direction of the current, the direction of the magnetic field can be changed, thereby controlling the direction of movement of the mover.

[0027] The master control unit matches the force feedback requirements of different game scenes, such as resistance when shooting and rebound force after pulling the trigger, by presetting current values, and can also dynamically adjust the coil current to change the output force size and direction according to game input signals such as weapon recoil force and collision strength.

[0028] When the trigger is not pressed, the mover is located at the initial position, the elastic element keeps the trigger reset, and no current passes through the coil; when the user presses the trigger, the transmission mechanism drives the permanent magnet mover to move along the guide rail, triggering the position sensor to detect the displacement; the sensor detects the position and force of the trigger in real time and transmits the signal to the control unit, and the master control unit calculates the required force feedback effect, such as the size of the resistance, the strength of the recoil, the strength and frequency of the vibration, etc., according to the preset algorithm and game instructions, analyzes and outputs the first PWM control signal, adjusts the H-bridge circuit output corresponding current, and then drives the permanent magnet mover to move, generates resistance or auxiliary thrust in the opposite direction of the user's pressing direction, outputs the second PWM control signal, and drives the vibration motor to generate a response vibration feedback; after the user releases the trigger, the elastic reset element provides a reset force, the master control unit cuts off the coil current, and the mover returns to the initial position.

[0029] The game handle disclosed by the utility model can simulate various force feedback effects, for example:

[0030] Resistance, simulating the resistance feeling when pulling the trigger;

[0031] Recoil, simulating the recoil when shooting a gun;

[0032] Vibration touch, simulating the vibration feeling when exploding or colliding;

[0033] Pulse touch, simulating the pulse touch when an object collides or a mechanism starts.

[0034] The utility model provides a kind of gamepad, including a force feedback trigger based on electromagnetic linear actuator, can provide more real immersive game experience for player.
