A wearable mechanical auxiliary arm for carrying based on the principle of leverage

Abstract

The invention discloses a lever-principle-based wearable mechanical auxiliary arm for carrying. The arm comprises a front arm, a rear arm and a power assisting device. The front arm and the rear arm are each of a hollow column with openings in two ends. One end of the front arm is a stretching-out end, the other end of the front arm is a spherical connection end, and the middle of the outer side of the column body is provided with an annular guide groove. One end of the rear arm is a stretching-in end, and the other end of the rear arm is a cylindrical connection end. The power assisting device comprises a front arm rotating frame, a connection rod, a spring, a rear arm rotating frame, a fixed magnet and a movable magnet. The two sides of the connection rod are connected with the front arm rotating frame and the rear arm rotating frame correspondingly. The fixed magnet is arranged on one side of the rear arm, and the movable magnet is an annular magnet and movably arranged on the column body of the rear arm. The two ends of the spring are connected with the connection rod and the movable magnet correspondingly. The front arm and the rear arm are connected through a universal bearing, free rotation of the front arm and the rear arm is achieved, the movement range of the arm is ensured, the connection rod is pulled through force between the magnets, the weight of carried objects is reduced, heavy objects such as a motor are omitted, the structure is simple, and the device is easy and convenient to use.

Description

technical field [0001] The invention relates to the field of power-assisted machinery, in particular to a wearable mechanical auxiliary arm for carrying based on the principle of leverage. Background technique [0002] The mechanical arm is very helpful to the direction of handling and storage. It can actively pull us to lift and reduce the weight of objects during work, thereby reducing human labor intensity and fatigue, thereby improving labor productivity and reducing the weight of objects. Work errors due to human or automated robot factors. The existing power-assisted mechanical arms are often complex in structure, and the size is tailored for the user, resulting in high production costs and cannot be popularized and used. Contents of the invention [0003] The purpose of the present invention is to provide a wearable mechanical auxiliary arm for carrying based on the principle of leverage. The existing auxiliary mechanical arm is often complex in structure and the s...
