In this embodiment, flexible laminating strip 520 sets up at the outer border of inspection door 500, namely on keeping away from the border of pivot 630 one side, and extends to the one side of keeping away from inspection door 500, can utilize flexible laminating strip 520 to go to compensate the too big problem in great gap between inspection door 500 and the door, has reduced because of the too big passenger that causes in gap grabs and holds up injured's problem.
Further, pressing piece 530 has the face that is used for compressing tightly flexible laminating strip 520, still is equipped with the overhanging board 531 that extends to keeping away from flexible laminating strip 520 one side at the middle part of face, and the setting of overhanging board 531 can increase the bulk strength who presses piece 530, improves the reliability that compresses tightly. In this embodiment, in order to avoid the influence of the bolt connection on the external appearance of the inspection door 500, a plate body is arranged at the end of the stud, the plate body is clamped between the inspection door 500 and the pressing member 530, and the pressing member 530 is effectively pressed against the flexible attachment strip 520 by screwing the nut at the outer end of the stud.
As a specific implementation manner of the embodiment of the present invention, please refer to fig. 1, the inspection door 500 is provided with an abdicating space 540 recessed inwards, a handle 550 is provided in the abdicating space 540, and the inner wall of the inspection door 500 is provided with a reinforcing plate 560 respectively connected to the upper and lower ends of the handle 550. In this embodiment, the inspection door 500 is substantially L-shaped, a side surface of the inspection door 500 near the rotation shaft 630 is parallel to an inner wall of the vehicle body, and the other side surface of the inspection door 500 extends to a side near the door perpendicular to the inner wall of the vehicle body.
In order to improve the convenience of opening the inspection door 500, a handle 550 is provided at the outer side of the inspection door 500, the handle 550 is located at a position between both side surfaces of the inspection door 500, and the handle 550 extends in the up-down direction for easy grasping. In order to maximize the in-vehicle space, a local region of the inspection door 500 is configured to be concave inwards to form a yield space 540 for accommodating the handle 550, a top surface of the inspection door 500 forming the yield space 540 is configured to extend from outside to inside gradually to the lower side, and a bottom surface of the inspection door 500 forming the yield space 540 is configured to extend from outside to inside gradually to the upper side, so that the configuration can achieve good transition and also facilitate the formation of the inspection door 500.
Further, because the position where the handle 550 is connected with the inspection door 500 is stressed greatly when the door is opened and closed, in order to improve the installation strength of the handle 550 on the inspection door 500, the reinforcing plate 560 is arranged in the region of the inspection door 500 inside the abdicating space 540, and when the handle 550 is connected with the inspection door 500, the reinforcing plate 560 needs to be penetrated, so that the connection strength is effectively increased, and the service life of the inspection door 500 is prolonged.
The vehicle door vertical cover plate structure can be widely applied to rail vehicles such as motor train units, urban rails, subways and carbon steel vehicles, accords with the development directions of functionalization, light weight, integration and modularization, and has wide application prospect.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
