Problems solved by technology

However, the pantograph of the existing structure maintains the pressure by squeezing the power supply network upwards, and the structure is complex and the maintenance cost is high
When docking and charging between the pantograph slide and the power supply line, the pantograph slide cannot adjust its height adaptively to make it in stable contact with the power supply line, which will seriously affect the safety and reliability of charging, and may be damaged in severe cases vehicle
At the same time, the existing pantograph structure makes it easy for the vehicle to derail from the power supply line when it deviates left and right in the lane. Once derailed, it needs to be parked and manually reset. This power supply method cannot meet the driving needs of electric vehicles, especially those driving on expressways. Require

Abstract

The invention relates to the field of power supply technologies for electric vehicles, in particular to a pantograph and an electric vehicle with the same. The pantograph comprises a pantograph assembly. The pantograph assembly comprises a pantograph slide plate assembly, an upper support arm, a lower support arm, a pantograph support, movable tracks, expansion mechanisms and a translation mechanism, the pantograph slide plate assembly is perpendicular to a power supply line, the translation mechanism is further arranged on the movable tracks, and the expansion mechanisms are arranged betweenthe upper support arm and the pantograph support and between the lower support arm and the pantograph support. The pantograph is arranged on the top of the electric vehicle. The electric vehicle further comprises a data processing unit and a tracking device. The tracking device is arranged on the top of the electric vehicle, and the expansion mechanisms, the translation mechanism and the trackingdevice are in signal connection with the data processing unit. The pantograph and the electric vehicle have the advantages that the height of the pantograph can be adaptively adjusted, the pantographcan be in excellent contact with the power supply line even when the electric vehicle is deviated in lanes in the left-right directions, accordingly, power supply can be guaranteed against being interrupted, and the charge safety of the electric vehicle can be improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle power supply, in particular to a pantograph and an electric vehicle using the pantograph. Background technique [0002] The pantograph is an electrical device for an electric vehicle to obtain electric energy from the power supply network. It is installed on the roof of the electric vehicle. In the charging system, the pantograph is an essential component. However, the pantograph of the existing structure maintains the pressure by pressing the power supply network upwards, and the structure is complex and the maintenance cost is high. When docking and charging between the pantograph slide and the power supply line, the pantograph slide cannot adjust its height adaptively to make it in stable contact with the power supply line, which will seriously affect the safety and reliability of charging, and may be damaged in severe cases vehicle. At the same time, the existing pantograph structur...
