As shown in Fig. 1 and Fig. 2, the car roof structure of the present invention includes a cover plate assembly, and the two ends of the cover plate assembly are bent downward to have a limit portion 111 and a limit portion 121 for cooperating with the side beam of the car compartment. , the bottom of the cover plate assembly is provided with reinforcing beams 5, and the top of the cover plate assembly is provided with aluminum beading bars 2 at the left and right ends and the front and rear sides. Wherein, the cover plate assembly includes at least two plates connected end-to-end. One end of the plate body 11 connected to the adjacent plate body 12 is bent upward with a connecting portion. The riveting hole, that is, the bent connecting portion 112 of the plate body 11 is riveted with the bent connecting portion 122 of the plate body 12 , and the connecting portion is covered by the connecting piece 3 . Both ends of the connector 3 are respectively connected to the two boards by riveting, and both ends of the connector 3 are provided with riveting holes for connecting with the board 11 and the board 12 . The middle part of the connecting piece 3 arches upwards to cover the connecting portion of the two panels, effectively preventing rainwater from penetrating into the interior of the compartment from the connecting portion, and simultaneously improving the strength of the cover plate. The aluminum bead on the front side of the top of the cover assembly is an L-shaped structure, and the front side adopts an L-shaped aluminum bead, so that one end of the aluminum bead realizes the connection between the panel body and the side beam of the carriage, and the other end protects the side beam and the panel body of the carriage. During the running of the vehicle, the front side of the compartment box directly impacts the wind force, avoiding the front of the compartment box body from directly bearing the wind force when the vehicle is running, and effectively preventing tension between the top cover, aluminum bead, and compartment side beams caused by excessive wind force. crack.
