Charging device for rail traffic vehicle

Abstract

The invention discloses a charging device for a rail traffic vehicle. The charging device for the rail traffic vehicle comprises an electrical storage device, a collecting shoe, a rotating shaft and a driving piece which are arranged on the vehicle; the electrical storage device is used for supplying electricity to the vehicle; the collecting shoe is electrically connected with the electrical storage device and arranged on the rotating shaft; and the driving piece is suitable for driving the collecting shoe to rotate around the rotating shaft and extend outwards, when the vehicle pulls in, the collecting shoe extends out of a vehicle body of the vehicle to be connected with external electricity supply equipment, and the external electricity supply equipment charges the electrical storage device through the collecting shoe. Thus, through cooperation of the electrical storage device, the collecting shoe, the rotating shaft and the driving piece, the process of manual treating of connection of the charging device for the rail traffic vehicle and the electricity supply equipment can be omitted, electric shock of people can be prevented, and thus the charging safety of the rail traffic vehicle can be improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a charging device for rail transit vehicles. Background technique [0002] In related technologies, rail transit vehicles generally provide power to the vehicle by setting a contact rail or pantograph along the line, and by contacting the collector shoe on the vehicle with the contact rail or pantograph. Since a contact rail or a pantograph needs to be arranged along the line, the cost of this power supply method is high; at the same time, once a fault occurs in one part of the contact rail or pantograph, it will cause the power supply failure of the whole line. [0003] Also some rail transit vehicles are provided with electric storage devices that provide electric energy for the rail transit vehicles. After the vehicles stop at the station, the on-board electric storage devices need to be charged. This power supply method requires manual connection of the on-board electric dev...

Problems solved by technology

Since a contact rail or pantograph needs to be installed along the line, the cost of this power supply method is high; at the same time, once a fault occurs in one place of the contact rail or pantograph, it will cause the power supply failure of the whole line

[0003] Also some rail transit vehicles are provided with electric storage devices that provide electric energy for the rail transit vehicles. After the vehicles stop at the station, the on-board electric storage devices need to be charged. This power supply method requires manual connection of the on-board electric devices to the ground The charging pile is connected and then charged; after the charging is completed, it is necessary to manually disconnect the on-board electrical device from the charging pile again, which is inconvenient to operate. Manually plugging and unplugging the charging device will not only prolong the charging time, but also cause the risk of electric shock
