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 conveyance based on the principle of lever. Background technique [0002] The robotic arm is very helpful to the direction of the storage and transportation. It can actively pull us to lift and reduce the weight of objects during work, thereby reducing human labor intensity and reducing human fatigue, thereby improving labor productivity and reducing Work errors caused by manual or automatic robot factors. Existing power-assisted manipulators are often complicated in structure and customized in size for users, which results in high production costs and cannot be promoted. Summary of the invention [0003] The purpose of the present invention is to provide a wearable mechanical auxiliary arm for conveyance based on the principle of lever. For the existing power-assisted mechanical arms, the structure is often complicated and the size is ta...
