Abstract

The invention discloses a six-freedom-degree mechanical arm for an automatic charging pile of an electric vehicle and a control method of the six-freedom-degree mechanical arm for the automatic charging pile of the electric vehicle comprises a base plate rotating actuator, a rotating base plate, a big arm frontward inclination actuator, a middle arm inclination actuator, a forearm inclination actuator, a first support, a second support, a charging gun rotating actuator, a charging gun, a charging gun support and a charging gun pitching actuator. Spatial motion of the charging gun on an automatic charging arm is achieved through linkage control over the six-freedom-degree mechanical arm. A linear Hall sensor senses a magnetic field of a magnet at the center of a charged connector of the electric vehicle, simple locating is conducted, then a position sensitive detector PSD on the electric vehicle senses a laser emitted out by a laser collimation emitter, accurate locating is conducted, and finally the position of the charged connector of the electric vehicle is determined; and the charging gun is smoothly inserted into the charged connector of the electric vehicle.

Description

technical field [0001] The invention relates to a mechanical arm and a control method thereof, in particular to a six-degree-of-freedom mechanical arm for an electric vehicle automatic charging pile and a control method thereof. Background technique [0002] Electric vehicles are the development trend of the automobile industry. Charging piles, as an indispensable accessory facility for electric vehicles, have extremely broad application prospects. But the existing charging piles are all manual type. Because the charging gun is connected with heavy wires, the overall mass is relatively large, so there are many inconveniences in manual charging. There are greater difficulties in the electrical interface. At the same time, with the advancement of technology, three-dimensional garages and unmanned self-service charging stations have emerged accordingly, all of which have put forward requirements for charging piles that can automatically charge electric vehicles.
