Embodiment 1

[0022] Such as figure 1 and 2 As shown, a bionic forearm wearable mechanism includes a forearm sleeve composed of a first sleeve 1 and a second sleeve 2 . The first sleeve 1 and the second sleeve 2 are parallel to each other. A first swivel 3 and a second swivel 4 are installed between the first sleeve 1 and the second sleeve 2 . The axes of the first sleeve 1 , the first swivel 3 , the second swivel 4 and the second sleeve 2 are coincident, and they can rotate with each other. The first sleeve 1 and the second sleeve 2 have the same structure, and the first swivel 3 and the second swivel 4 have the same structure.

[0023] Such as image 3 As shown, the outer peripheral surface of the first sleeve 1 is integrally formed with two arm sleeve fixed ends 5 , and the two arm sleeve fixed ends 5 are evenly distributed outside the first sleeve 1 . An annular protrusion 13 is integrally formed on the outer peripheral surface of the first sleeve 1 .

Abstract

The invention relates to a bionic wearable structure, in particular to a bionic forearm wearable mechanism. The bionic forearm wearable mechanism comprises a forearm sleeve, a rotating structure capable of rotating relative to the forearm sleeve is installed on the forearm sleeve, the rotating structure comprises a first rotating ring and a second rotating ring which can rotate mutually, and the forearm sleeve and the rotating structure are connected through a power assisting structure. The bionic forearm wearable mechanism which is small in wearable mechanism size, light in mass and good in flexibility and conforms to the biomechanical characteristics of the forearm of a human body is provided. The technical problems that in the prior art, a bionic elbow joint wearable mechanism is large in size, heavy in mass and poor in flexibility are solved.

Description

technical field [0001] The invention relates to a bionic wearable structure, in particular to a bionic forearm mechanism based on a tensioned integral structure. Background technique [0002] The bionic elbow wearable robot has the characteristics of high motion flexibility and strong adaptability, and can realize the flexion and extension of the elbow with adaptive semi-autonomous reset during the wearing motion process. Compared with traditional industrial robots and rigid structure robots, the bionic elbow-joint wearable robot based on tensegrity can face different environmental conditions, such as working conditions such as forces in non-design direction of motion, and can be formed through the tensegrity structure. The unique tension grid distributes the impact force evenly on each component, improves the ability to deal with the impact force, and enables the mechanism to withstand large impacts without failure or even damage. However, the existing forearm joint wearab...
