Abstract: A force feedback device includes a base, a working body, a driving assembly, and a transmission structure. The working body includes a key assembly and a working surface. The working surface is disposed on the key assembly. The working body is rotatably connected to the base through a first transmission shaft. The driving assembly is rotatably disposed on the base. The driving assembly is disposed opposite to the working surface. The transmission structure is disposed on the working surface. The transmission structure is in transmission connection with the driving assembly. Compared with the related art, the first transmission shaft of the driving assembly provides forward and reverse rotation to drive the transmission structure to realize force feedback effects, which is compact in overall space, small in friction resistance, and facilitates user experience effect.

Abstract: The present disclosure discloses a force feedback device including a supporting bracket, a trigger hinged to the supporting bracket through a rotating shaft, a transmission shaft connected to the trigger, a driving assembly for providing an acting force to the trigger through the transmission shaft, and a reset member. A direction of the acting force is opposite to a direction of pulling the trigger. The driving assembly includes a magnetic circuit system and a coil fixed to the transmission shaft and generating an electromagnetic induction force with the magnetic circuit system. The electromagnetic induction force is transmitted to the trigger through the transmission shaft for forming the acting force. A handle using the force feedback device is also disclosed. The force feedback device and the handle disclosed by the present disclosure enable users to obtain richer game experiences according to different game scenarios.

Abstract: Disclosed is a method for inducing orderly arrangement by means of polymer crystallization, and the use thereof in preparing a composite film. Firstly, monodisperse PS-DVB nano-microspheres of different sizes are prepared by means of soap-free emulsion polymerization; the PS-DVB nano-microspheres prepared above are used as raw material, and PEG aqueous solutions with different concentrations are added to induce an orderly arrangement of the nano-microspheres by means of solution-state PEG crystallization; and characterized by using scanning electron microscopy and polarizing microscopy. The method is simple in terms of operation and is widely applicable. By further modifying the orderly arrangement of the nano-microspheres, the composite material can be applied to different fields.
