Patent ID: 8505392

Claim:
A mobile platform with six degrees of freedom, comprising: a static base plate defining six spherical ball sockets on a surface thereof; a dynamic moving plate adjustably and movably mounted upon the static base plate, the dynamic moving plate defining six spherical ball sockets on a surface of the dynamic moving plate, and facing toward the static base plate; and six branched chains adjustably assembled between the static base plate and the dynamic moving plate, enabling the dynamic moving plate to move relative to the static base plate along six degrees of freedom, each of the branched chains comprising a main body, two assembly portions adjustably and slidably mounted to two ends of the main body, and two ball heads, each of the assembly portions comprising a connecting rod, and the two ball heads formed at two distal ends of the connecting rod, respectively, wherein the two ball heads of each branched chain respectively rotatably engages with one corresponding ball socket of the static base plate and one corresponding ball socket of the dynamic moving plate, each of the static base plate and the dynamic moving plate defines six assembly recesses; the spherical ball sockets are correspondingly defined in the assembly recesses; each of the fixing assemblies comprises a ball cover mounted to one corresponding distal end of the connecting rod and fixed to one corresponding assembly recess of the static base plate or the dynamic moving plate, each fixing assembly comprises a seal and a plurality of fixing components, the seal is sleeved on the connecting rod of the assembly portion together with the ball cover, and is positioned between the main body and the ball cover, each recess further defines a plurality of fixing holes surrounding the ball socket; the seal is has a substantially same shape as the ball cover, and is fixed to the corresponding assembly recess of the static base plate or the dynamic moving plate by the plurality of fixing components covering the corresponding ball socket.
