Wherein, the trigger key rotates anticlockwise around the rotating shaft 60, the swing rod has a movement trend of rotating clockwise under the driving of the motor and the reduction gearbox, and the left end of the swing rod always supports against the right end of the transmission part 12, so that the rotation of the trigger key cannot be prevented, resistance can be generated to the movement of the trigger key, and the experience of force feedback can be provided for a user.
Example 2
In order to realize different force feedback responses generated in different scenes, on one hand, the movement rotating angle of a trigger key is monitored by increasing Hall elements, on the other hand, the rotating angle of a potentiometer for feeding back a swing rod in real time is increased, and the output of a motor is controlled by the mutual matching of the Hall elements and the potentiometer, so that the swing rod can output different torques, and different force feedback responses are realized.
It should be noted that the force feedback assembly 30 of the present application is small and can be adapted to, but not limited to, a VR gamepad.
In summary, the key assembly 100 according to the embodiment of the present application is a miniature key assembly 100, which not only can provide force feedback and optimize the experience of the user, but also can reduce the volume and realize the miniature design through the modular design.
The present application further provides an electronic device including the key assembly 100 according to any of the above embodiments. The electronic device may be a game pad, a game machine, a remote controller, etc., and since the key assembly 100 can provide force feedback and reduce the occupied space, the electronic device of the embodiment of the present application also has the same beneficial effects, which are not described herein again.
Although some specific embodiments of the present application have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are for illustrative purposes only and are not intended to limit the scope of the present application. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the present application. The scope of the application is defined by the appended claims.
