Strike reaction force generation module based on linear motor and elastomer and its control method

Abstract

The present invention relates to a striking reaction force generating module based on a linear motor and an elastic body and a method for controlling the same. More specifically, the invention is a striking reaction force generating module based on a linear motor and an elastic body, comprising: a housing forming the exterior of the striking reaction force generating module; an elastic body pad disposed on the upper side of the housing to generate a striking reaction force when a user strikes an actuator; a pad-shaped structure disposed on the lower side of the elastic body pad to maintain a gap for generating a striking reaction force below the elastic body pad; and a driving unit installed on the lower side of the pad-shaped structure to raise and lower the pad-shaped structure toward the elastic body pad. In addition, a control method for a strike reaction force generating module based on a linear motor and an elastic body according to the features of the present invention is a control method for a strike reaction force generating module based on a linear motor and an elastic body, comprising: (1) a strike reaction force generating module comprising a housing forming the exterior of the strike reaction force generating module, an elastic body pad disposed on the upper side of the housing to generate a strike reaction force when a user strikes an actuator, a pad-shaped structure disposed on the lower side of the elastic body pad to maintain a gap for generating a strike reaction force below the elastic body pad, and a driving unit installed on the lower side of the pad-shaped structure to raise and lower the pad-shaped structure toward the elastic body pad; a step of driving the driving unit disposed inside the housing forming the exterior of the strike reaction force generating module to raise and lower the pad-shaped structure; (2) a step in which the pad-shaped structure is raised or lowered according to the operation of the driving unit of step (1) to maintain a preset gap with the elastic body pad; and (3) the elastic pad is characterized by a step of providing a sensation that the user can feel by generating a reaction force upon impact when struck by the user, while the gap is maintained through height adjustment of the pad-shaped structure in step (2). According to the linear motor and elastic body-based impact reaction force generating module and control method proposed in the present invention, the module is configured to include a housing forming the exterior of the impact reaction force generating module, an elastic body pad disposed on the upper side of the housing to generate an impact reaction force when a user strikes the actuator, a pad-shaped structure disposed on the lower side of the elastic body pad to maintain a gap for generating an impact reaction force under the elastic body pad, and a driving unit installed on the lower side of the pad-shaped structure to raise and lower the pad-shaped structure toward the elastic body pad. By adjusting the gap between the elastic body pad and the pad-shaped structure, the width is adjusted, and when a user strikes the actuator, it is possible to provide a sensation of striking various objects according to the width of the adjusted gap. In addition, according to the linear motor and elastic body-based impact reaction force generation module and control method of the present invention, the width is adjusted by adjusting the gap between the elastic body pad and the pad-shaped structure, and by providing a sensation of striking various objects according to the width of the adjusted gap when the user strikes the actuator, the user can experience the sensation of striking various objects even with a single actuator, and the convenience and efficiency of use can be further improved by allowing the user to feel the sensation of striking various objects by adjusting the width between the elastic body pad and the pad-shaped structure.
