Embodiment 1

[0023] like Figure 1-2 As shown, this embodiment provides a thumb drive mechanism for a hand function rehabilitation robot, including a support 3, a linear driver 2 and a linkage mechanism, the bottom end of the linear driver 2 is hinged on the support 3, and the output end is connected to the support 3. The linkage mechanism is hinged; the end of the linkage mechanism that is not connected to the linear actuator 2 is hinged on the support 3, and the linkage mechanism is used to connect and fix the thumb, and drive the linkage through the change of the stroke of the linear actuator 2 The location of the institution changes.

[0024] In this embodiment, the bottom end of the linear driver 2 is hinged on the support 3 through the fixed shaft 1; the output end of the linear driver 2 is screwed with a universal ball head 4, and the universal ball head 4 is rotatably installed in a ball-head pressing block 5, and the ball-head pressing block 5 is fixed on the linkage mechanism th...

Abstract

The invention discloses a thumb driving mechanism for a hand function rehabilitation robot, which relates to the technical field of rehabilitation training for sick thumbs, and mainly includes a support, a linear driver and a linkage mechanism. The bottom end of the linear driver is hinged on the support, and the output One end of the linkage mechanism is hinged to the linkage mechanism; one end of the linkage mechanism not connected to the linear driver is hinged to the support, the linkage mechanism is used to connect and fix the thumb, and the linkage mechanism is a double quadrilateral linkage mechanism. The present invention adopts a double quadrilateral linkage mechanism and a linear drive structure to ingeniously convert linear motion into rotational motion, easily realize passive bending of the thumb, improve comfort, and perform operations more smoothly and without stagnation.

Description

technical field [0001] The invention relates to the technical field of rehabilitation training for sick thumbs, in particular to a thumb drive mechanism for a hand function rehabilitation robot. Background technique [0002] The function of the thumb is not only to achieve bending and abduction, but also to rotate 360 ​​degrees around the lower joint of the thumb, which is flexible; at the same time, it can cooperate with the four fingers to achieve various stretching and grasping actions. When the thumb is sick or injured, it is often necessary to use the thumb training device to assist in the functional rehabilitation training of the thumb; specifically, to realize the bending of the thumb, cooperate with the four fingers to realize the grasping function of the hand, and help the patient realize the function of the hand. [0003] However, the existing training device may be stuck in the execution operation, and the bending action of the thumb cannot be well realized. Con...
