a serpentine arm

Abstract

The invention discloses a snakelike arm. The snakelike arm is provided with an arm body, wherein the arm body is formed by connecting multiple connecting rods in series. Every two adjacent connecting rods are movably connected through a cross shaft joint. A pair of first shaft forks are arranged on the upper end face of each connecting rod, wherein each pair of first shaft forks are in pivot connection with one set of pivot shafts of the corresponding cross shaft joint; and a pair of second shaft forks are arranged on the lower end face of each connecting rod, wherein each pair of second shaft forks are in pivot connection with the other set of pivot shafts of the corresponding cross shaft joint. The pair of first shaft forks on the upper end face of each connecting rod are arranged to be staggered with the pair of second shaft forks on the lower end face of the corresponding connecting rod by 90 degrees. Four sets of through holes are formed in the positions, corresponding to the two sets of pivot shafts of the corresponding cross shaft joint, on the upper end face and the lower end face of each connecting rod. All through holes of each set of the first through holes are distributed in a central-symmetry manner. The two sets of pivot shafts of each cross shaft joint each sequentially penetrate the corresponding first through hole in the corresponding connecting rod located below the pivot shafts through four pull ropes and are each connected to a corresponding driving unit; rotation of the cross shaft joints is controlled through traction, applied to the pull ropes, of the driving units so that multi-dimensional movement of the snakelike arm can be controlled; high-flexibility operational capacity is achieved.

Description

technical field [0001] The invention relates to the technical field of automatic charging of electric vehicles, and more particularly relates to a snake-shaped mechanical arm used for technical equipment of automatic charging robots for electric vehicles. Background technique [0002] With the popularity of electric vehicles in the world and at home, and with the rapid development of the time-sharing rental business of electric vehicles as the background, the humanized management problems of time-sharing rental of electric vehicles have also emerged, especially the charging method of electric vehicles. [0003] At present, the traditional charging methods use charging stations or set up electric vehicle charging piles in different areas of the city. The charging process is completely dependent on manual operation and has a low degree of automation, especially for time-sharing leased electric vehicles. [0004] The realization of automatic charging and unmanned fully automati...

AI Technical Summary

Problems solved by technology

However, in the existing technology, the traditional industrial manipulator is limited by stiffness and size, its degree of freedom is limited, and its environmental adaptability is poor, so it is difficult to be competent for the automatic charging process of electric vehicles
