Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully and specifically with reference to the accompanying drawings and preferred embodiments, but the scope of the present invention is not limited to the following specific embodiments.

Example (b):

as shown in fig. 1 and 2, the cabin door subdivision sealing structure of the passenger car of the embodiment includes a cabin door 1 and a partition plate 2, the partition plate 2 divides a storage cabin body 3 into a ventilation chamber 31 and a waterproof chamber 32, the cabin door 1 is provided with a ventilation area 11 and a waterproof area 12 corresponding to the ventilation chamber 31 and the waterproof chamber 32, respectively, when the cabin door 1 is closed on the storage cabin body 3 of the passenger car, the ventilation area 11 is closed at an opening of the ventilation chamber 31, and the waterproof area 12 is closed at an opening of the waterproof chamber 32. The internal region of the storage cabin body 3 is directly divided by the arrangement structure, and the electric component and the chassis component can be respectively stored according to requirements, so that the electric component and the chassis component are isolated, the heat dissipated by the chassis component is effectively prevented from increasing the temperature of the electric component through air heat exchange, and the abnormal function and even damage of the electric component are avoided. In addition, just because the parts that will demand difference separate the storage, consequently can set up the device according to the demand in respective storage area, the suitability is higher to the structure of this embodiment has only carried out simple change on original storage cabin body 3's basis, does not occupy extra space, consequently can not receive the space restriction of passenger train.

In this embodiment, the sealing member 4 is disposed at the edge of the waterproof region 12 and/or the edge of the waterproof chamber 32, and when the cabin door 1 is closed, the sealing member 4 seals the gap between the waterproof region 12 and the waterproof chamber 32, so as to prevent liquid and humid gas from entering, so that the electrical component requiring waterproof is always in a dry environment, thereby reducing the risk of electric leakage and prolonging the service life of the electrical component. And the sealing member 4 can also play a dustproof role, so that the cleaning frequency of the electrical components is reduced.

In this embodiment, the sealing element 4 includes a sealing rubber strip and a seam allowance strip, the seam allowance strip is arranged along the edge of the waterproof compartment 32, and the sealing rubber strip is connected to the seam allowance strip; an L-shaped aluminum plate 13 corresponding to the seam allowance strip is arranged on the framework of the cabin door 1, one side surface of the L-shaped aluminum plate 13 is fixedly connected with the framework of the cabin door 1, and when the cabin door 1 is closed, the sealing rubber strip is abutted against the other side surface of the L-shaped aluminum plate 13. In this embodiment, four sealing members 4 are provided, one sealing member 4 is provided on each of the side wall pillars on both sides of the waterproof compartment 32, the single-shaft hinge mounting plate, and the edge of the partition plate 2, and the position of the sealing member 4 corresponding to the hatch door 1 is shown by a dotted line in fig. 2. In other embodiments, other connection modes and other connection positions may also be selected as appropriate, which is not described herein.

In this embodiment, the partition board 2 is perpendicular to the cabin door 1, and the cabin door 1 is provided with a beam 14 at a projection position of the partition board 2 and is divided into a ventilation area 11 and a waterproof area 12 by the beam 14. Since the cross member 14 corresponds to the position of the partition 2, a good sealing effect can be achieved by providing the sealing member 4 on both of them when the hatch door 1 is closed.

In this embodiment, since the ventilation chamber 31 is no longer required to prevent water and limit temperature of the electrical component, the ventilation area 11 may be provided with a ventilation opening 111 communicating the ventilation chamber 31 and the outside of the cabin door 1, thereby achieving a good ventilation effect on the chassis component.

In this embodiment, as shown in fig. 2, the ventilation opening 111 is a plurality of strip-shaped holes arranged in parallel, and this arrangement structure can ensure the structural strength of the cabin door 1 and ensure the overall stress performance of the structure while satisfying the good ventilation effect.
