Abstract: A joint structure of a telescopic cylinder includes a telescopic unit, an extension unit and a first fixing unit. The telescopic unit includes a first main body, a first combined structure and at least one first fixing structure. The extension unit includes a second main body, a second combined structure and at least one second fixing structure. The first combined structure is screwed to the second combined structure. The first fixing unit includes at least one first fixing body, and the first fixing body is simultaneously arranged in the first fixing structure and the second fixing structure and interferes with the first main body and the second main body so as to prevent the first combined structure and the second combined structure from spiral movement.

Abstract: A motion simulating apparatus and actuating system includes a base; a movable platform arranged above the base; a first cross arm assembly disposed on a first side between the base and the movable platform. The first cross arm assembly includes a first arm and a second arm that are cross-connected to each other; a second cross arm assembly disposed on a second side between the base and the movable platform relative to the first side. The second cross arm assembly includes a third arm and a fourth arm forming an X-shaped connection; an actuator connected obliquely to an upper part of the first arm and the base or the lower part of the third arm to drive the movable platform to move along a first direction or its opposite direction; and a rod is horizontally connected with the upper part of the first arm and an upper part of the third arm. The base, the movable platform, the first arm and the third arm form a substantially parallelogram when the actuator is actuating.

Abstract: A motion simulator includes a base plate, a motion platform, a first actuator, a base, a second actuator and a carrying platform. The motion platform is arranged on the base plate and movably connected to the base plate. The first actuator is arranged on the motion platform, movably connected to the motion platform. The base has a base body extending in a length direction and a base extension surface extending in a width direction. The first actuator is movably connected to the base extension surface. The second actuator is movably arranged on the base. The carrying platform is movably connected to the second actuator. Through a connection relationship between the base and the second actuator, the first actuator performs a left-right movement of the carrying platform relative to the motion platform and the second actuator performs the forward-backward movement of the carrying platform relative to the motion platform.

Abstract: A motion simulating apparatus includes a support base, a coupling part, an occupant platform adapted to carry one or more occupants, and two linear actuators. The coupling part is pivotally connected to the support base about a first pivot axis. The occupant platform is disposed above the support base and is pivotally connected to the coupling part about a second pivot axis, the first pivot axis being substantially orthogonal to the second pivot axis. The two linear actuators are respectively disposed at two opposite sides of the second pivot axis, wherein the two linear actuators are respectively connected pivotally to the support base and are respectively connected pivotally to the occupant platform at the two opposite sides of the second pivot axis.

Abstract: A kinesthetic device that simulates flight includes a base unit and a swing unit. The base unit includes a base seat; whereas, the swing unit includes a swing seat, two swing support structures pivoted between the base seat and the swing seat, and a swing actuator used to control the swing positions of the two swing support structures. The two swing support structures are equal in length and parallel to each other. A fixed baseline is formed between two junction points between the two swing support structures and the base seat, a swing baseline is formed between two junction points between the two swing support structures and the swing seat, and the fixed baseline and the swing baseline are equal in length. The two swing support structures, the fixed baseline and the swing baseline form a parallelogram, allowing the swing support structures to swing stably the base seat.
