Abstract
Provided is a force feedback apparatus, including a housing, a rotation shaft fixed to the housing, a trigger movably connected to the rotation shaft and movable relative to the housing, and a force feedback assembly. The force feedback assembly includes a driving magnet fixed to a side of the trigger toward the housing, an iron core fixed to the housing and arranged opposite to the driving magnet, and a driving coil wound around the iron core. The driving coil is energized to interact with the driving magnet to generate force feedback on the trigger. The force feedback apparatus requires no additional transmission structure and directly provides force feedback through interaction between two driving elements, thereby realizing timely force feedback on the trigger and reducing the assembly difficulty while simplifying the structure. In addition, forces in two directions can be directly generated on the trigger by changing a driving current.
