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

Guideway vehicle outside hermatic door

Technical field

The utility model relates to a kind of outside hermatic door that is used for guideway vehicle, belongs to mechanical manufacturing field.

Background technology

The speed per hour of present domestic guideway vehicle has reached more than 200 kilometers, and this rigidity and light-weight design for vehicle part is had higher requirement.

The existing outside hermatic door that is used for guideway vehicle, the bivalve sliding door that generally adopts stopping sliding door or constitute by aluminium alloy panel and section bar skeleton.Hermetically-sealed construction such as rubber element that the external side of door adopts, its with doorframe between combine undertighten, thereby sealing effectiveness is not good.Adopt structures such as inflating rubber capsule for another example in addition, correspondingly manufacturing cost is higher again.Still there are not at present the improvement that takes into account above-mentioned two aspects and the scheme of optimizing structure.

The utility model content

Design goal of the present utility model is to provide a kind of guideway vehicle outside hermatic door, is reaching under the prerequisite that rigidity and light-weight design require, and adopts the air sac sealing structure and improves a body single-piece outside sealing effectiveness.

For realizing above-mentioned design goal, described guideway vehicle outside hermatic door includes:

Frame section bar skeleton, paper wasp nest liner, internal hilar plate and external door panel, wherein,

Internal hilar plate and external door panel are plugged in frame section bar skeleton respectively, are filled with paper wasp nest liner between internal hilar plate and external door panel.

Internal hilar plate, external door panel and paper wasp nest liner are pressed into as a whole structure by adhesives.

Outer setting one annular groove at frame section bar skeleton is equipped with an annular seal air bag in groove.

As above-mentioned scheme feature, by internal hilar plate and external door panel difference plug side frame section skeleton, then filling, bonding paper wasp nest liner and pressing are an integral structure, can realize body integral rigidity and intensity preferably.

Simultaneously, the annular seal air bag of hermatic door outer setting, under the promotion of hermatic door by driver train, air bag directly pressed to doorframe and improve and doorframe between sealing property.

Further improvement project is, described frame section bar skeleton, and its inner corner is the right angle, and outside four corners are the great circle arc angle.

Thus, hermatic door is finished the control that hermatic door is moved by driver train in the open and close process, and when switched the open and close position between while hermatic door and the doorframe, easier formation with doorframe sealed or the disengaging doorframe air bag.

As mentioned above, the advantage of the utility model guideway vehicle outside hermatic door is further to realize rigidity, intensity and weight-saving designing requirement, and adopt the air sac sealing structure can realize the external side seal of door again better.

Description of drawings

Fig. 1 is a described outside hermatic door scheme drawing;

Fig. 2 is that A-A among Fig. 1 is to generalized section;

Fig. 3 is that B-B among Fig. 1 is to generalized section.

As shown in Figure 1 to Figure 3, forms 1, annular seal air bag 2, frame section bar skeleton 3, paper wasp nest liner 4, internal hilar plate 5 and external door panel 6.

The specific embodiment

Embodiment 1, and as shown in Figure 1 to Figure 3, described guideway vehicle outside hermatic door includes forms 1, annular seal air bag 2, frame section bar skeleton 3, paper wasp nest liner 4, internal hilar plate 5 and external door panel 6.Wherein,

Internal hilar plate 5 and external door panel 6 are plugged in frame section bar skeleton 3 respectively.The corner, inside of frame section bar skeleton 3 is the right angle, and its outside four corners are the great circle arc angle.

Be filled with paper wasp nest liner 4 between internal hilar plate 5 and external door panel 6, internal hilar plate 5, external door panel 6 and paper wasp nest liner 4 are pressed into as a whole structure by adhesives.

Outer setting one annular groove at frame section bar skeleton 3 is equipped with an annular seal air bag 2 in groove.

Different materials can be decorated or select for use to internal hilar plate 5 as required with the surface of external door panel 6.
