Problems solved by technology

In contrast, the multi-joint exoskeleton has a better power-assisted effect, but it is also more complicated in terms of structural design and driving methods
At present, the multi-joint power-assisted exoskeleton at home and abroad mainly has problems such as complex structure, weak bionicity, poor wearing comfort, and unsatisfactory power-assisted effect.

Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0030] like Figure 1 to Figure 9 As shown, a bionic knee-ankle joint-assisted exoskeleton device of the present invention includes a knee joint movement module 1 , a lower leg module 2 , and an ankle joint movement module 3 . The bionic knee-ankle joint assisted exoskeleton device respectively realizes knee joint flexion / extension single-degree-of-freedom movement and ankle joint dorsiflexion / plantarflexion and varus / valgus two-degree-of-freedom movement. Among them, the knee joint movement is actively driven by a motor.

[0031] like Figure 4 As shown, the knee joint movement module 1 includes: a femoral connecting rod 101, a motor fixed connection shaft plate 102, a motor output plate frame 103, an integrated servo gear motor 104, a femoral connecting plate 105, a telescopic pull rod 106, a bionic knee joint structure 107, Tibial c...

Abstract

The invention discloses a bionic knee-ankle joint power-assisted exoskeleton device which comprises a knee joint movement module, a shank module and an ankle joint movement module, one end of the shank module is connected with the knee joint movement module, and the other end of the shank module is connected with the ankle joint movement module. According to the invention, knee joint flexion / extension single-degree-of-freedom movement and ankle joint dorsal flexion / plantar flexion and introversion / extroversion two-degree-of-freedom movement are realized, and human body walking is assisted, so that the assisting effect is achieved. Knee joint movement is driven by a motor, the knee joint movement module adopts a human knee joint bionic design, and the shank module is provided with a height adjusting design, so that the requirements of different people can be met. The bionic knee-ankle joint assisting exoskeleton device has the advantages of being simple in structure, easy to wear and high in crowd adaptability.

Description

technical field [0001] The invention relates to the technical field of lower extremity exoskeleton, in particular to a bionic knee and ankle joint assisting exoskeleton device for assisting the movement of human knee and ankle joints. Background technique [0002] The lower extremity exoskeleton is a mechanical system that can be worn on the outside of the human body, which can support, assist and protect the wearer. The lower extremity exoskeleton has the ability to provide sufficient strength and endurance for the wearer, and is widely used. It can not only assist the elderly with insufficient lower limb strength and inconvenient walking and carry weight in the civilian field, but also assist soldiers in the military and fire rescue fields. And firefighters complete special tasks such as long-distance walking, carrying heavy objects, and transporting the wounded. In addition, in the medical field, rehabilitation exoskeletons can effectively assist patients in rehabilitati...
