Problems solved by technology

[0003] In the related technology, the new energy vehicle adopts a groove on the road surface to charge the vehicle. The technical solution is actually a concave arc surface groove installed under the road surface groove, and the receiver is charged in contact with the arc surface groove. The charging current contactor has complex structure and heavy weight, which affects the cruising range of the car body, and this technical solution is not suitable for use on rail vehicles

Abstract

The invention discloses a charging device of a rail vehicle and a rail transit system. The charging device of the rail vehicle comprises a charging knife and charging rails; the charging knife is electrically connected with an energy storage device of the rail vehicle; the charging rails comprise first charging boards and second charging boards; the first charging boards and the second charging boards are arranged in a spaced manner to construct a groove body; and the first charging boards and the second charging boards both comprise multiple sections of section boards which are electrically connected with each other in sequence in the running direction of the rail vehicle. According to the charging device of the rail vehicle, when the charging knife enters into the groove body, the charging knife is electrically connected with the first charging boards and the second charging boards to charge the energy storage device of the rail vehicle. Moreover, the multiple sections of section boards can prolong the contacting distances between the charging knife and the first charging boards and the contacting distances between the charging knife and the second charging boards, and thereforethe rail vehicle can be enabled to charge enough electric quantity into the energy storage device in the running process.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular, to a charging device for rail vehicles and a rail transit system. Background technique [0002] Rail vehicles usually use flexible catenary to take power, and use pantograph-catenary or shoe-rail contact charging. This power-taking method arranges power grids along the entire line, and the investment cost of power-taking methods is generally high. The development potential of transport electric locomotives is huge. [0003] In the related technology, the new energy vehicle adopts a groove on the road surface to charge the vehicle. The technical solution is actually a concave arc surface groove installed under the road surface groove, and the receiver is charged in contact with the arc surface groove. The charging current receiving contactor is complex in structure and heavy in weight, which affects the cruising range of the car body, and this technical solution is not suitab...
