Abstract

The invention relates to the electric receiving device of the electric vehicle. The current receiver for current in and return comprises the electric boots and the spring device, with two parallel parallelogram four linking bar structure and a separation structure, each four link structure made by the top and down lining bars hinged to the corresponding side plate and isolation plate, the separation structure composed of the air cylinder, air cylinder linking pole hinged to the cylinder piston end, lower linking brake bar with two rocker arms with the lower linking brake bar hinged to the lower linking bar pin shaft fixed to two side walls, one of the rocker arm hinged to the air cylinder linking bar, the other being the stop leaning against the low linking bar, each isolation plate bottom installed with an electric receiving boot, each four link bar structure having its top link bar connected to the said spring device. It solves the technical issues of current receiver contact or separation with the electric supply track smoothly, and the grounding issue of it.

Description

Technical field: [0001] The invention relates to a power receiving device of an electric vehicle, in particular to a power receiving and return device used in a high-speed magnetic levitation train. Background technique: [0002] Urban traffic such as light rail and subway are driven by electric power. There are catenary or power supply rails for power supply system along the line. Electricity, or through the contact of the current collector fixed at the bottom of the vehicle and the power supply rail to obtain electric energy. In addition, it is necessary to form a current loop through the walking contact of the wheels on the grounded track, so as to realize the driving of electric power and the power consumption of various equipment. Therefore, during the whole operation process, the pantograph or the current collector is always in contact with the catenary or the power supply rail. [0003] Maglev trains, especially high-speed maglev trains with a speed of more than 430...
