Ground mobile charging robot applied to electric automobile based on magnetic suspension internal rotor flywheel energy storage

Abstract

The invention discloses a ground mobile charging robot applied to an electric automobile based on magnetic suspension internal rotor flywheel energy storage. Position change between a charging base station and a target to-be-charged vehicle is achieved through an ultrasonic sensor, a visual sensor and a roller installed on a bearing piece in the robot, and automatic charging is achieved on the electric automobile through two magnetic suspension energy storing flywheels in opposite rotation directions assembled in a base. The magnetic suspension energy storing flywheels are upper and lower structure bodies with the same installation structure which are up-down installed on a middle separation plate between an inner circular ring and an outer circular disc of flywheel bodies. The high speed rotation of the magnetic suspension energy storing flywheels depends on driving of a rotary alternating magnetic field. The alternating magnetic field is achieved based on a working principle of a direct-current motor which is of a flat-shaped hollow cup structure and used for converting electric energy into rotation kinetic energy of the magnetic suspension energy storing flywheels.

Description

technical field [0001] The present invention relates to a charging robot, more particularly, to a ground mobile charging robot applied to electric vehicles based on energy storage of a magnetic levitation inner rotor flywheel. Background technique [0002] Pure electric vehicles have the advantages of environmental protection, low noise, and small size, and have broad application prospects for future urban transportation. However, due to various technical reasons, the application and popularization of pure electric vehicles are limited. One of the more prominent problems is the difficulty of charging. Mainly reflected in the following aspects: [0003] (1) The charging time is long, fast charging takes 3 to 5 hours, and slow charging takes more than 10 hours. [0004] (2) The charging depth is not enough, and most electric vehicles cannot travel to the rated mileage after being fully charged. [0005] (3) The charging pile is fixed, and the parking space is easily occupie...
