Anti-collision structure for road vehicle sliding-plug door system

Abstract

The invention discloses an anti-collision structure for a road vehicle sliding-plug door system. The anti-collision structure comprises a door body with two folio door leaves which can perform translational motion mutually, and further comprises a first restraining mechanism and a second restraining mechanism, wherein the first restraining mechanism is arranged above the side, close to a vehicle door frame, of the door body; the second restraining mechanism is arranged below the door body; when the door body is closed, the first restraining mechanism connects the door body to the vehicle door frame, while when the door body is opened, the first restraining mechanism separates the door body from the vehicle door frame; and the second restraining mechanism always connects the door body to the vehicle body frame. By adoption of the anti-collision structure, not only can the door body be prevented from being opened due to a collision when being closed and can the rigidity and strength of the door body be improved, but also the door body can be guided and restrained in a multi-point manner when being opened and closed, so that smooth opening/closing action can be realized, vertical column mechanisms on the two sides of the door body are eliminated, and then the interior space of a road vehicle is larger.

Description

technical field [0001] The invention relates to a sliding door for a vehicle, in particular to an anti-collision structure for a sliding door for a vehicle. Background technique [0002] Sliding doors are usually installed on large vehicles such as railway vehicles, subway vehicles and buses, especially on high-speed railway vehicles, the application of sliding doors is particularly important. The sliding door is a type of door that makes the outer surface of the sliding door coincide with the outer surface of the vehicle body when the entrance and exit are closed. According to such a sliding door, noise such as air resistance and wind noise can be reduced. [0003] Such as figure 1 As shown in the figure, the two mutually perpendicular directions of X and Y are shown in the figure. This figure shows the closed state of the sliding door. At this time, the sliding door 1' is flush with the car body 2'. Driven by the drive system, The sliding door 1' first moves outwards al...

AI Technical Summary

Problems solved by technology

[0006] The plug door with this structure has the following disadvantages. The uprights 5' on both sides of the door frame of the car body occupy the space in the car, and it is easy to bump into passengers when turning, which is unsafe; moreover, the two uprights 5' have a large number of structural parts and a complicated structure. , which increases the weight of the entire door system; when the door is closed in place, the columns on both sides of the door frame of the car body only serve as a connection, which does not increase the locking reliability when the door is closed in place, so when the door is closed, it is easy to be deformed and opened by passengers
