Abstract

The utility model relates to an outer side sealing door of a rail vehicle; the sealing door meets the requirements of the rigidity and light-weighted design, adopts an air bag sealing structure and improves the overall outer side sealing effect. The sealing door comprises a frame profile skeleton, a paper honeycomb lining, an inner door panel and an outer door panel. The inner and the outer door panels are spliced into the frame profile skeleton; the paper honeycomb lining is filled between the inner door panel and the outer door panel. The inner door panel, the outer door panel and the paper honeycomb lining are pressed into a whole structure by bond. A circular groove is arranged outside the frame profile skeleton; and the groove is provided with a circular sealing airbag. In the sealing door, the inner door panel and the outer door panel are spliced into the frame profile skeleton, filled and adhered with the paper honeycomb lining and pressed into the whole structure, which can quite well realize the overall rigidity and strength of the door. When the sealing door is pushed by a driving mechanism, the circular sealing airbag arranged outside the sealing door is directly pressed to a door frame, thereby improving the sealing performance with the door frame.

Description

Rail vehicle outside airtight door

technical field

The utility model relates to an outer sealing door for rail vehicles, which belongs to the field of mechanical manufacturing.

Background technique

At present, the speed of domestic rail vehicles has reached more than 200 kilometers per hour, which puts forward higher requirements for the rigidity and lightweight design of vehicle components.

Existing outer sealed doors for rail vehicles generally adopt sliding doors or double-shell sliding doors made of aluminum alloy panels and profile frameworks. The sealing structure used on the outside of the door body, such as rubber components, is not tightly combined with the door frame, so the sealing effect is not good. Another example is also to adopt structures such as inflatable rubber bags, and the corresponding manufacturing cost is higher again. At present, there is no improvement and optimization structure scheme taking into account the above two aspects.

Utility model content

The design purpose of the utility model is to provide an outer sealing door of a rail vehicle. On the premise of meeting the design requirements of rigidity and light weight, an airbag sealing structure is adopted to improve the overall outer sealing effect of the door body.

In order to achieve the above-mentioned design purpose, the outer sealing door of the rail vehicle includes:

Frame profile skeleton, paper honeycomb lining, inner door panel and outer door panel, among which,

The inner door panel and the outer door panel are respectively plugged into the frame profile frame, and the paper honeycomb lining is filled between the inner door panel and the outer door panel.

The inner door panel, outer door panel and paper honeycomb inner lining are pressed into an integral structure by adhesive.

An annular groove is arranged on the outside of the frame profile skeleton, and an annular airtight air bag is installed in the groove.

According to the characteristics of the above scheme, the inner door panel and the outer door panel are respectively inserted into the framework of the frame profile, and then filled and bonded with the paper honeycomb lining and pressed together to form an overall structure, which can better realize the overall rigidity and strength of the door body.

At the same time, the ring-shaped airtight air bag arranged outside the airtight door is directly pressed against the door frame by the drive mechanism of the airtight door to improve the sealing performance between the air bag and the door frame.

A further improvement solution is that, the inner corners of the frame profile frame are all right angles, and the outer four corners are large arc angles.

Therefore, during the opening and closing process of the airtight door, the driving mechanism completes the control of the action of the airtight door. At the same time, when the open and closed positions between the airtight door and the door frame are switched, the air bag can more easily form a seal with the door frame or break away from the door frame.

As mentioned above, the advantage of the utility model rail vehicle outer sealing door is that the design requirements of rigidity, strength and light weight are further realized, and the air bag sealing structure can better realize the outer sealing of the door body.
