Embodiment Construction

[0034] The structural form of the rehabilitation gait trajectory generator in this embodiment is: including a power unit, a transmission unit and a movement trajectory generating unit.

[0035] see figure 1 , figure 2 , The structure of the power unit is set as follows: the output shaft of the driving motor 1 installed on the motor flange 2 is connected with the drive sprocket shaft 18 through a coupling 21 .

[0036] Such as figure 1 , figure 2 with image 3As shown, the structure of the transmission unit is set as follows: the transmission sprocket shaft 18 is simply supported by the "T" bearing seat 5 fixedly installed on the bottom plate 17, and the transmission sprocket 3 and the transmission chain 4 are engaged on the transmission sprocket shaft 18. The drive chain 4 transmits the drag force to the dragging small sprocket 20 installed on the small sprocket shaft 19, mounts and runs the small sprocket 23 with the small sprocket shaft 19, sets the large sprocket shaf...

Abstract

The invention discloses a rehabilitation gait track generator which is characterized by comprising a power unit, a transmission unit and a movement track generation unit, wherein the movement track generation unit comprises a multi-constraint loading mechanism and an I-shaped guide rail; the multi-constraint loading mechanism includes mutually constraint bearings which are arranged on different surfaces of the I-shaped guide rail and comprise check ring type cam follower needle roller bearings which generate contact force with the roller operating surface of the guide rail; the roller operating surface is arranged according to a gait matching track which is obtained through matching based on a normal gait track of an ankle joint of a lower limb of human body. According to the rehabilitation gait track generator, with the adoption of a foot traction manner, standard gait motivation which is matched with the lower limb gait track is provided for lower limb rehabilitation training so as to obtain better rehabilitation efficacy and rehabilitation judgment.

Description

technical field [0001] The invention relates to a gait trajectory generator for lower limb rehabilitation training, which belongs to the field of rehabilitation robots. It is used for recovery training of physical rehabilitation for patients with walking disabilities caused by cerebral palsy, hemiplegia, stroke or accidents. Background technique [0002] Many countries in the world are gradually entering an aging society. At the same time, the number of patients with lower limb movement disorders caused by medical diseases such as cerebral palsy, hemiplegia, and stroke or accidents continues to increase. Clinical medicine has proved that in addition to drug therapy and surgical treatment, necessary rehabilitation training for such patients can prevent joint contracture, help the functional recovery of muscles, and improve the final recovery degree of patients. Due to the patient's limited mobility or physical strength, rehabilitation training cannot be completed alone. Trad...
