Embodiment Construction

[0022] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] figure 1 Shown is a mechanical arm of a cable-driven exoskeleton according to the present invention, which can be used for comprehensive rehabilitation training of patients, and particularly preferably, for upper limb rehabilitation training. When a disabled patient receives rehabilitation treatment, the mechanical arm of the present invention is worn on the patient, and can replace the rehabilitation therapist to perform long-term, stable and accurate rehabilitation training on the patient.

[0024] Human upper limbs include shoulders, upper arms, forearms and hands, including shoulder joints, elbow joints, wrist joints and finger joints. The robotic arm mainly involves the movement of the three joints of the shoulder joint, elbow joint and wrist joint. Corresponding to the joints of the human upper limbs one by one, the degree of fr...

Abstract

The invention discloses a rope-driven pulley of a rope-driven exoskeleton mechanical arm. The rope-driven pulley comprises bearings (701 and 702), a round wheel (703), a screw (704), a base (705), sleeves (706, 707 and 708) and a bearing retainer (709). The bearings (701 and 702) and the sleeves (706, 707 and 708) are arranged on the screw (704), the round wheel (703) is arranged on the bearings (701 and 702) and clamped by the bearing retainer (709), and the screw (704) is fixed to the base (705). The rope-driven pulley aims at solving the problems that an existing rope-driven pulley of a rope-driven exoskeleton mechanical arm is complex in structure and small in bearing moment of force.

Description

technical field [0001] The invention relates to a transmission pulley for an exoskeleton mechanical arm, belonging to the technical field of rehabilitation medicine. Background technique [0002] When the upper limbs are injured due to various reasons, in order to restore limb functions faster and better, rehabilitation treatment is particularly important. However, when patients, especially severely disabled patients receive treatment, they need long-term one-on-one company and repeated training under the guidance of the therapist. The training process of this therapy is simple, but the work intensity is high and requires the therapist to have highly proficient skills. [0003] With the development of robot technology and the advantages of robots in simple and repetitive tasks, research on robotic arms assisting patients in rehabilitation has begun at home and abroad, and many countries have achieved corresponding results. The CADEN-7 rehabilitation manipulator of the Univ...
