Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] like figure 1 As shown, the multi-degree-of-freedom energy storage foot mechanism includes a foot unit 1, a side plate unit 2, an ankle joint unit 3, and a binding unit 5. The ankle joint unit 3 is detachable from the side plate unit 2 and the foot unit 1 through screws. connection, the binding unit 5 can be detachably connected with the sole unit 1 and the ankle joint unit 3, the ankle joint unit 3 includes an ankle support base 301, and the ankle joint support base 301 includes an integrally formed support platform and hanging ears. There is a through hole, and the ankle joint toe flexion and dorsiflexion shaft 302 and the bearing are installed in the through hole so that the ankle joint support seat 301 is rotatably assembled in the side plate unit 2, and the support table is detachably connected to the energy storage unit, and the energy storage unit includes a p...

Abstract

The invention discloses a multi-DOF (degree of freedom) energy-storing foot mechanism, comprising a sole unit, a side plate unit, an ankle unit and a binding unit. The ankle unit is releasably connected with the sole unit through the side plate unit; the binding unit is releasably connected with both the sole unit and the ankle unit; the ankle unit includes an ankle support that includes a supportterrace and a hanger lug that are integrated; the hanger lug is provided with a through hole; an ankle toe-flexure dorsal-flexure spindle and a bearing are mounted in the through hole so that the ankle support may be rotationally fitted to the side plate unit; the support is releasably connected with an energy-storing unit. The multi-DOF energy-storing foot mechanism has the advantages that energy loss can be effectively decreased, a multi-direction DOF is achieved, the structure is simple, wearing is facilitated, comfort is better for a wearer, parts are convenient to manufacture and mount,the multi-DOF energy-storing foot mechanism is highly transplantable and may be used with any limb-assistant exoskeleton, and the production cost may be greatly reduced since no drive and control system is provided.

Description

technical field [0001] The invention relates to a lower limb rehabilitation training mechanism, in particular to a multi-degree-of-freedom energy storage foot mechanism. Background technique [0002] The lower extremity exoskeleton robot is a wearable mechanical device integrating robotics technology, automation technology, and information sensing technology, which can assist the wearer to complete rehabilitation training exercises. Lower extremity exoskeleton robots generally contain multiple joints, including hip joints, knee joints, and ankle joints. The ankle joint and its foot mechanism bear the impact brought by the wearer's movement, so this part of the mechanism has important role. Some ankle joints and foot mechanisms of lower limb power-assisted exoskeletons are combined into active ankle joints with 1, 2 or 3 degrees of freedom by rigid versions, which are usually driven by motors, hydraulic pressure, or pneumatics. Difficulty, high cost, high energy consumption...
