Embodiment 1

[0029] In this embodiment, the flexible and wearable lower limb power-assisted exoskeleton clothing includes high-waist shorts 3, knee pads 2, shoes 4, a controller, traction belt 5 and two driving devices 1, and the high-waist shorts 3 are located at the left and right hip joints and the sacrum. A gyroscope sensor is installed, and an adjustable belt 6 is fixed on the waist position of the high-waisted shorts, and the two driving devices 1 are symmetrically installed on the adjustable belt 6 on the front of the high-waisted shorts 3, and each driving device 1 All are connected with the upper end of a traction belt 5, the lower end of the traction belt 5 passes through the knee pad 2, and is connected with the shoe 4, and each driving device is used to drive the ankle joint movement of the corresponding side; three gyro sensors and two driving devices They are all connected to the controller; the controller is used to process the data of the three gyroscope sensors and control ...

Embodiment 2

[0035] The connection and positional relationship of each part of this embodiment is the same as that of Embodiment 1, the difference is that the stretchable waist belt 6 and the high-waisted shorts 3 are connected by ultra-thin back-to-back Velcro straps, and are equipped with connecting buckles, adjustable waist size, plastic The buckle is tied at the waist. This design is flexible, light in weight, easy to wear and adjust, and suitable for the daily life of the wearer. The traction belt 5 is a nylon belt with good flexibility and small quality, which is convenient to wear and adjust, and is suitable for the daily life of the wearer. The high-waist shorts 3 are thin elastic pants, which can meet the common needs of wearers in a certain weight range to a certain extent.

Abstract

The invention provides a flexible wearable lower limb assistant exoskeleton suit. The suit is characterized by comprising high waist short pants, knee caps, shoes, a controller, a traction belt and two drive devices. The left and right hips joints and sacrum position of the high waist short pants are all provided with gyroscope sensors. The waist position of the high waist short pants is fixedly provided with an adjustable belt. The two drive devices are symmetrically installed at the adjustable belt located at front side of the high waist short pants in a left-right mode. Each drive device is connected with the upper end of a traction belt. The lower end of the traction belt penetrates through the kneed caps to be connected with the shores. Each drive device is used for driving the corresponding ankle joint move; the three gyroscope sensors and two drive devices are all connected with the controller; the controller is used for processing the data of three gyroscope sensors and controlling the motion of power elements of the drive devices, the knee caps are located at the knee joints and is provided with a plurality of magic sticker pasting points of different lengths, and the knee caps are also provided with knee dents.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a wearable flexible lower limb exoskeleton suit. Background technique [0002] Nowadays, the aging population is serious, which has brought a great burden to society and families. Elderly people living alone lack escorts, making it inconvenient for them to go out for a walk. At present, most of the existing exoskeletons are rigid structures, which make it inconvenient to wear, difficult to walk, large in size, clumsy in movement, and do not match the expected movements of the operator. Can not flexibly adapt to different operators. [0003] The Chinese patent application number 201510574501.5 discloses a bionic flexible lower extremity exoskeleton suit driven by pneumatic artificial muscles, which has disadvantages: the flexible rope and the shoe are hinged because the torque is too small to achieve the dorsiflexion effect of the foot, and the flexible straps are all on the thig...
