Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings.

[0012] refer to figure 1 , figure 2 , the exoskeleton with two degrees of freedom hip joint assisted movement of the present invention includes a chassis 1, a Y-axis motor bracket 3, an X-axis motor bracket 13 and a gear bracket 7 are fixed on the chassis 1, and the Y-axis motor 2 is fixed on the Y-axis motor bracket 3 Above, the X-axis motor 12 is fixed on the X-axis motor bracket 13. Here, the X-axis motor and the Y-axis motor can use servo motors to facilitate angle control. In the illustrated example, the pulley 4 is fixed on the rotating shaft of the Y-axis motor 2 , the input shaft 23 of the double cross universal joint 9 fixes the pulley 6 , and the pulley 4 and the pulley 6 are connected by a belt 5 . The X-axis secondary transmission mechanism includes a pulley 14, a belt 15, a pulley 16, a pulley 17, a belt 18 and a pulley 20, the pulley 14 is fixed on the...

Abstract

The invention relates to a hip joint exoskeleton for carry out two degrees of freedom auxiliary movement, which can enable patients to take two degrees of freedom movement exercises of hip joint internal flexion and external extension with the help of exoskeleton for auxiliary movement by using a double cruciform universal joint and controlling the rotation angles of an X-axis motor and a Y-axis motor. Compared with the prior hip joint exoskeleton, the inventive hip joint exoskeleton has the advantages of novel structure, light weight, flexible operation, and convenience for wearing. The exoskeleton can be fixed at the outer side of the hip joint of a patient, an angular transducer installed on a rotation pair is used for obtaining hip joint movement parameters of the patient, and a computer is used for controlling the rotation angle of the X-axis motor and the Y-axis motor to drive the patient to conduct rehabilitation exercises.

Description

technical field [0001] The invention relates to exoskeleton hip joint assisted rehabilitation exercise medical equipment, in particular to an exoskeleton with two degrees of freedom for hip joint assisted movement. Background technique [0002] Joint movement rehabilitation training for patients with limb disabilities needs to rely on medical rehabilitation aids. Traditional exoskeleton medical rehabilitation aids usually use a single-degree-of-freedom joint series mode, which has a complex structure and poor rigidity. Contents of the invention [0003] The object of the present invention is to provide an exoskeleton with two degrees of freedom for auxiliary motion of the hip joint. [0004] The exoskeleton with two degrees of freedom hip joint auxiliary movement of the present invention comprises a chassis, a Y-axis motor bracket, an X-axis motor bracket and a gear bracket are fixed on the chassis, the Y-axis motor is fixed on the Y-axis motor bracket, and the rotating sh...
