Shock generating device for simulation gun

A shock generating device for a simulation gun, comprising:

• a housing;
• a driving motor outside the housing and having a rotating shaft protruding inside the housing;
• a first gear fixed to the rotating shaft of the driving motor;
• a two-stepped gear with a second gear receiving the rotating force of the first gear and a third gear integrally formed with the second gear around the same axis;
• a fourth gear receiving the rotating force of the second and third gears;
• a hook integrated coaxially with the fourth gear and extended to the outer circumferential surface of the fourth gear;
• a lever having a body that contacts the inner wall of the housing, a free end extended from the body and engaged by the hook, and a fixed end extended from the body and rotatably fixed on the housing, the body, the free end, and the fixed end being integrally formed;
• and
• an elastic member for pressing the body of the lever to contact the inner wall of the housing.

An apparatus for simulating recoil in a simulation gun having a trigger that is grasped and pulled by a user to a firing position to simulate the firing of the simulation gun, comprising:

• an impact surface disposed within the simulation gun and connected to the interior of the simulation gun such that movement of the surface results in a corresponding movement of the simulation gun;
• an impact member moveable within the simulation gun and having sufficient mass such that impact of the member on the impact surface can cause movement of the simulation gun perceptible to the user of the simulation gun;
• and
• an electromechanical drive mechanism operatively connected to the impact member to cause the impact member to reciprocate between a first position engaging the impact surface and a second position wherein the impact member is disengaged from the surface, the drive mechanism being adapted to drive the impact member in response to movement of the trigger toward the firing position to impact the impact surface and cause movement of the simulation gun perceptible to the user of the simulation gun.
