  • Publication number: 20240197422
    Abstract: The master-end operating device includes a device body, operating mechanisms, a movable member and an elastic member. The operating mechanisms are pivotably connected to the device body, and each is provided with a respective driving part. The movable member is at least partially disposed within the device body and configured to be movable in an axial direction of the device body, where the movable member is provided with follower parts, each of which interferes with the respective driving part to enable the movable member to be movable in the axial direction. The respective follower part has a first constraint surface, which includes at least one bent portion recessed toward a central plane of the device body. The elastic member is configured to provide an elastic force to drive the movable member to move toward a top end of the master-end operating device.

  • Patent number: 10208806
    Abstract: A compliant safe joint and manufacturing method thereof. The compliant safe joint includes an input axis circumferentially connected to a motor shaft of a DC motor; a movable bridge circumferentially mounted on the input axis and slidable along a axial direction of the input axis; multiple bearings, each of the multiple bearings having an inner ring fixed to the movable bridge and having an outer ring; a stationary bridge rotatably mounted on the movable bridge and having a helicoid surface, the outer ring of each bearing being movable along the helicoid surface; and a flexible component connected to the movable bridge. The stationary bridge rotates about the input axis when a torque which exceeds a predetermined threshold is applied to the stationary bridge by the motor shaft, such that the bearings move with respect to the helicoid surface to cause the flexible component to be compressed and extended through the movable bridge.
