Soft-contact automatic charging device for electric vehicles

Abstract

The invention discloses a soft contact type automatic charging system of an electric automobile and a device of the soft contact type automatic charging system. The soft contact type automatic charging system and the device thereof comprise the electric automobile and a vehicle-mounted battery, and are characterized in that a vehicle-mounted battery telescopic electrode device is arranged under a chassis of the electric automobile; a gear box is arranged in a midpoint of a rotating shaft of the vehicle-mounted battery telescopic electrode device; a step motor which is integrally connected with the gear box is arranged on the right side of the gear box; a flange screw cylinder is arranged on the right side of each of two circular cylinders; the flange screw cylinders can rotate to be perpendicular to the ground; two telescopic electrode metal plates on right screw rods of the flange screw cylinders are enabled to extend to be in contact with ground electrode metal plates; the two ground electrode metal plates are connected with a relay in a charging box on a road lamp pile through wires, and the relay is connected with a charger through the wires; and an urban power cable is enabled to enter the charging box to be connected with the relay. The soft contact type automatic charging system and the device thereof disclosed by the invention have the advantages of being reasonable in design, easy to manufacture, convenient and reliable in charging and good in safety performance.

Description

technical field [0001] The invention relates to a soft-contact automatic charging device for electric vehicles, which belongs to the technical field of electric vehicles. Background technique [0002] With the development of the automobile industry, problems such as shortage of oil resources, high price and environmental pollution have become increasingly serious. The advantages of electric vehicles, such as no fuel consumption, high energy efficiency and no pollution, are the development direction of the automobile industry. [0003] Electric vehicles use the power of the on-board battery to supply the motor to work. When the electric vehicle travels to a certain distance, the power of the on-board battery is insufficient, and the on-board battery needs to be charged. At present, to charge an electric vehicle, it is necessary to park the electric vehicle next to the charging pile, then manually pull out the cable plug from the charging pile and insert it into the charging ...
