Motion platform having wire-shaped body winding mechanism

Abstract

The present invention provides a motion platform having a wire-shaped body winding mechanism, where the wire-shaped body winding mechanism is combined on one side of the motion platform to wind related pipelines, which prevents problems in operating security caused by dropping of overlong pipelines, makes the peripheral environment of the motion platform neat, and causes no vibration or noise pollution.

What is claimed is: 
     
         1 . A motion platform having a wire-shaped body winding mechanism, comprising:
 a fixed seat, providing a virtual reference point at a fixed position;   a movable seat, movably combined on the fixed seat and comprising a connecting portion, wherein the relative distance between the connecting portion and the reference point changes synchronously when the movable seat moves relative to the fixed seat;   a winding mechanism, disposed on the fixed seat and comprising a rotary member; and   a wire-shaped body, wound on the rotary member, and comprising one end connected to the connecting portion and the other end corresponding to the virtual reference point,   whereby the length of the wire-shaped body extending out of the winding mechanism changes with the coiling or release of the wire-shaped body by the winding mechanism when the movable seat moves relative to the fixed seat and changes the distance between the connecting portion and the reference point.   
     
     
         2 . The motion platform having a wire-shaped body winding mechanism of  claim 1 , wherein the winding mechanism is fixedly disposed on the fixed seat. 
     
     
         3 . The motion platform having a wire-shaped body winding mechanism of  claim 1 , wherein the winding mechanism is movably disposed on the fixed seat. 
     
     
         4 . The motion platform having a wire-shaped body winding mechanism of  claim 1 , wherein the rotary member further comprises a first central shaft and two second central shafts, the two second central shafts are parallel to the first central shaft, and the wire-shaped body is wound on the periphery of each second central shaft in an interlaced manner. 
     
     
         5 . The motion platform having a wire-shaped body winding mechanism of  claim 4 , wherein the rotary member has a first rotary body and two second rotary bodies, the first rotary body takes the first central shaft as a geometric center and rotates about the first central shaft, and the two second rotary bodies respectively take the second central shafts as geometric centers and are separately arranged at an axial end surface of the first rotary body. 
     
     
         6 . The motion platform having a wire-shaped body winding mechanism of  claim 5 , wherein the two second rotary bodies rotate about the two second central shafts respectively. 
     
     
         7 . The motion platform having a wire-shaped body winding mechanism of  claim 1 , wherein the winding mechanism further comprises an elastic member, and one end of the elastic member is connected to the rotary member. 
     
     
         8 . The motion platform having a wire-shaped body winding mechanism of  claim 1 , wherein the virtual reference point is located on the winding mechanism. 
     
     
         9 . The motion platform having a wire-shaped body winding mechanism of  claim 1 , wherein the virtual reference point is located on the fixed seat. 
     
     
         10 . The motion platform having a wire-shaped body winding mechanism of  claim 1 , wherein the wire-shaped body is a cable, wire, optical fiber, gas pipe, water pipe or oil pipe.
