The invention discloses a gap bridge structure of a railway vehicle, and a railway vehicle. The railway vehicle comprises the gap bridge structure, the gap bridge structure comprises containing grooves formed in the top of a carriage and connectors integrally fixed on the containing grooves. Two containing grooves are formed in the top of each carriage, and a low-voltage direct-current cable and a high-voltage alternating-current cable are respectively arranged in the two accommodating grooves and are connected with the connectors; plugs matched with the connectors are arranged at the two ends of a gap bridge cable, one end of the gap bridge cable is connected with the connector at the top of one carriage in an inserted mode, and the other end of the gap bridge cable crosses a through channel to be connected with the connector at the top of the adjacent carriage in an inserted mode. According to the gap bridge structure, car roof gap bridge is achieved, car roof gap bridge cannot affect the structural strength and air tightness of the whole carriage, the gap bridge structure is not affected by various factors such as outer blocking of the carriage and dividing wall space, and overhaul and maintenance are more convenient. In addition, the gap bridge structure is flexible in ungrouping and grouping, and a junction box does not need to be arranged, so that the gap bridge structure is simple in structure, small in arrangement space and low in configuration cost.
Description
technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a bridge structure for rail vehicles and a rail vehicle using the bridge structure. Background technique [0002] At present, the bridge cables of rail vehicles usually adopt the under-vehicle bridge or end wall bridge structure. When crossing the bridge under the car, the bridge cable needs to pass through the passenger compartment from the roof to the bottom of the car, which will occupy the space inside the car and affect the structural strength and airtightness of the whole car. However, crossing the bridge through the end wall will cause a series of problems due to many factors such as the outer seal and the space of the partition wall. [0003] Therefore, how to improve the bridge structure of rail vehicles is a technical problem to be solved by those skilled in the art. Contents of the invention [0004] In order to solve the above-mentioned technical problems, t...
