Abstract
An in-prosthesis linear drive system includes a holder frame, a power drive mounted on the holder frame, a screw nut mounted on the holder frame and coupled to the power drive and rotatable on the axis thereof by the power drive, a screw rod limiter including a center sliding guide rail mounted on the holder frame and a center sliding block slidable along the center sliding guide rail, and a screw rod threaded into the screw nut and connected with the center sliding block of the screw rod limiter and movable along the axial direction of the screw nut upon rotation of the screw nut. Thus, using the screw nut to drive the screw rod achieves the effect of minimizing the occupation of the prosthesis internal space.
Claims8
An in-prosthesis linear drive system, comprising:
- a holder frame;
- a power drive mounted on said holder frame;
- a screw nut rotatably mounted on said holder frame and coupled to said power drive and rotatable on the axis thereof by said power drive;
- a screw rod limiter comprising a center sliding guide rail mounted on said holder frame and extended along the axial direction of said screw nut, and a center sliding block mounted on and slidable along said center sliding guide rail;
- and
- a screw rod threaded into said screw nut, said screw rod having a terminal end parallel to the axial direction of said screw nut, said terminal end being provided with a terminal end portion connected to said center sliding block of said screw rod limiter such that said screw rod is axially movable forward or backward along the axial direction of said screw nut upon rotation of said screw nut.
