Electric vehicle pantograph

Abstract

The invention discloses an electric vehicle pantograph, which comprises a power transmitter fixed on a base, a receiving plate, and a beam frame composed of a beam, a pin and a support base, wherein the power transmitter is connected with the support base which is movably connected with the beam via the pin, and the receiving plate is sheathed with rotation shafts on two ends of the beam. The invention can resolve the problem that the stable contact between the receiving plate and the collecting plate is affected when the electrode of bow and the receiving plate of the pantograph are not parallel at right and left, thereby protecting electrodes and other elements under external force.

Description

technical field [0001] The invention relates to an electric vehicle pantograph. Background technique [0002] With the development and application of supercapacitor technology in urban public transportation, a variety of technologies involving electric vehicles have emerged. Chinese patent ZL03142211.X "Two-wire receiving type trolleybus pantograph" discloses a double-wire receiving type trolleybus pantograph; The utility model relates to a scissor-type double-pole pantograph for a bus tram. The lifting mechanism of the above two existing electric vehicle pantographs in China is hinged cantilever rotation and hinged parallelogram lifting. Smaller, it is not safe to use liquid (the medium is oil) to press the rotating cylinder, while the latter uses a large number of hinged linkages, with too many moving parts, no left and right swing function, and different lifts have different lifting forces. Different, so the failure rate is high. [0003] The above-mentioned existing ...

Problems solved by technology

The lifting mechanisms of the above two existing electric vehicle pantographs in China are hinged cantilever rotation and hinged parallelogram lifting. Smaller, it is not safe to use liquid (the medium is oil) to press the rotating cylinder, while the latter uses a large number of hinged linkages, with too many moving parts, no left and right swing function, and different lifts have different lifting forces. Different, so the failure rate is high

[0003] The pantograph of the above-mentioned existing electric vehicles, the electric receiving plate in contact with the external pantograph electrodes can only swing forward and backward along the axis of the vehicle, and cannot swing left and right, that is, there is no "universal" function, so once it is caused by road conditions and other reasons When the pantograph electrode and the receiving plate on the pantograph are not parallel in the left and right directions, it will affect the smooth contact between the receiving plate and the collecting plate. Under the forced action of external force, the electrodes and other components are easy to be damaged.
