Detailed implementation manners

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] The core of the present invention is to provide a water baffle installation device for rail vehicles, which can increase the passenger compartment space and reduce the weight of the rail vehicle body.

[0038] Please refer to Figure 1 , an embodiment of the present invention provides a water baffle installation device for rail vehicles, including a water baffle 1 and a waste exhaust air duct piece 2. The water baffle 1 includes a first connecting part 11, a second connecting part 12, a first water baffle body 13 connected to the first connecting part 11, and a second water baffle body 14 connected to the second connecting part 12. The first water baffle body 13 is connected to the second water baffle body 14, and there is an included angle between them; the waste exhaust air duct piece 2 includes a first waste exhaust air duct wall 21, a second waste exhaust air duct wall 22, a third waste exhaust air duct wall 23, and a third connecting part 24 connected in sequence. Corners are respectively formed between the first waste exhaust air duct wall 21 and the second waste exhaust air duct wall 22, between the second waste exhaust air duct wall 22 and the third waste exhaust air duct wall 23, and between the third waste exhaust air duct wall 23 and the third connecting part 24; the third connecting part 24 is attached and connected to the second connecting part 12, and the first waste exhaust air duct wall 21, the second waste exhaust air duct wall 22, the third waste exhaust air duct wall 23, the first water baffle body 13, and the second water baffle body 14 enclose to form a waste exhaust air duct 3.

[0039] That is to say, in this embodiment, the water baffle 1 and the waste exhaust duct member 2 are integrated into one, such that the water baffle 1 serves as the side wall of the waste exhaust duct 3. That is, the water baffle 1 not only functions to block water but also serves to form the waste exhaust duct 3. In this way, the waste exhaust duct 3 is formed by the water baffle 1 and the waste exhaust duct member 2 together. It is equivalent to replacing a part of the duct wall of the waste exhaust duct 3 in the related art with the water baffle 1, thereby enabling the overall installation of the waste exhaust duct 3 and the water baffle 1, saving structural space, reducing the structural space occupied by the water baffle 1 and the waste exhaust duct 3 as a whole, being beneficial to increasing the passenger compartment space of the rail vehicle, and being able to reduce the weight of the rail vehicle body 7.

[0040] It should be noted that this embodiment does not specifically limit the materials of the water baffle 1 and the waste exhaust duct member 2 respectively. For example, in some embodiments, the material of the waste exhaust duct member 2 is phenolic foam material, which has good heat insulation effect and low density. In some embodiments, the water baffle 1 is a magnesium alloy water baffle 1.

[0041] In addition, this embodiment does not limit the specific fixing method of the fitting connection between the third connection portion 24 and the second connection portion 12, as long as the fitting connection between the two can be achieved. In some embodiments, the third connection portion 24 and the second connection portion 12 are bonded. That is, the water baffle 1 and the waste exhaust duct member 2 are fixed through the fitting and bonding of the second connection portion 12 and the third connection portion 24.

[0042] In addition, as Figure 1 shown, in some embodiments, the second waste exhaust duct wall 22 is perpendicular to the first waste exhaust duct wall 21 and the third waste exhaust duct wall 23 respectively. Further, in some embodiments, the length of the first waste exhaust duct wall 21 is greater than the length of the third waste exhaust duct wall 23. One end of the first waste exhaust duct wall 21 away from the second waste exhaust duct wall 22 extends to one end of the first water baffle body 13 close to the first connection portion 11, and the third waste exhaust duct wall 23 is collinear with the second water baffle body 14. That is, the third waste exhaust duct wall 23 and the second water baffle body 14 form the same side of the waste exhaust duct 3.

[0043] As Figure 1 shown, in some embodiments, the first water baffle body 13 is inclined in a direction gradually approaching the second waste exhaust duct wall 22 from the end connected to the first connection portion 11 to the end connected to the second water baffle body 14.

[0044] In addition, as Figure 1As shown, in some embodiments, the water baffle 1 further includes a third water baffle body 15. The third water baffle body 15 is connected to one end of the second connecting portion 12 away from the second water baffle body 14. The third water baffle body 15 and the second water baffle body 14 are respectively connected to two ends of the cover plate 4. The cover plate 4, the second water baffle body 14, the second connecting portion 12, and the third water baffle body 15 form a cavity 5, and the cavity 5 is used to provide an installation space and / or routing. That is to say, in this embodiment, the water baffle 1 not only has the function of blocking water and forming the waste exhaust air duct 3, but also has the function of forming the cavity 5, so as to facilitate the installation and fixation of other structural members of the vehicle body 7, or facilitate routing.

[0045] As Figure 1 shown, in some embodiments, the second connecting portion 12 is respectively perpendicular to the second water baffle body 14 and the third water baffle body 15. The cover plate 4 is inclined from the end connected to the second water baffle body 14 to the end connected to the third water baffle body 15 in a direction gradually approaching the second connecting portion 12.

[0046] Further, as Figure 1 shown, in some embodiments, the water baffle 1 further includes a fourth water baffle body 16 and a fifth water baffle body 17. The fourth water baffle body 16 is connected to one end of the third water baffle body 15 away from the second connecting portion 12; the fifth water baffle body 17 is connected to one end of the fourth water baffle body 16 away from the third water baffle body 15; the fifth water baffle body 17 is provided with a fourth connecting portion 171, and the fourth connecting portion 171 is used to connect to the side wall panel 71 of the rail vehicle body 7.

[0047] It can be understood that through the transfer function of the fourth water baffle body 16, it is convenient to make the fourth connecting portion 171 of the fifth water baffle body 17 located at a suitable position. That is, by making the fourth water baffle body 16 and the third water baffle body 15 and the fourth water baffle body 16 and the fifth water baffle body 17 have appropriate angles respectively, the fifth water baffle body 17 can have a suitable position relative to the third water baffle body 15, so as to facilitate the connection of the fourth connecting portion 171 to the side wall panel 71 of the vehicle body 7.

[0048] As Figure 1 shown, in some embodiments, the third water baffle body 15, the fourth water baffle body 16, and the fifth water baffle body 17 form a Z-shaped structure. In this way, while ensuring the connection of the fourth connecting portion 171 to the side wall panel 71 of the vehicle body 7, it is beneficial to form a space between the fourth water baffle body 16 and the fifth water baffle body 17.

[0049] In addition, the above embodiments do not limit the connection methods of the cover plate 4 to the third water baffle body 15 and the second water baffle body 14 respectively, as long as the cover plate 4 can be driven and connected to the third water baffle body 15 and the second water baffle body 14 respectively.

[0050] In addition, the above embodiments do not limit the specific material of the cover plate 4. In some embodiments, the cover plate 4 is a PC cover plate 4.

[0051] As Figure 1 shown, in some embodiments, a first clamping portion is formed at the connection between the third water baffle body 15 and the fourth water baffle body 16, the second water baffle body 14 is provided with a second clamping portion, and the two ends of the cover plate 4 are respectively provided with a third clamping portion clamped with the first clamping portion and a fourth clamping portion clamped with the second clamping portion. That is to say, one end of the cover plate 4 is clamped with the first clamping portion through the third clamping portion to realize the connection between the cover plate 4 and the third water baffle body 15, and the other end of the cover plate 4 is connected with the second clamping portion through the fourth clamping portion to realize the connection between the cover plate 4 and the second water baffle body 14. The clamping connection method is simple and convenient to implement, and is detachable, which is convenient for maintaining the wiring in the cavity 5, etc. The specific structures of the first clamping portion, the second clamping portion, the third clamping portion and the fourth clamping portion in this embodiment are not limited, as long as the clamping between the first clamping portion and the third clamping portion and the clamping between the second clamping portion and the fourth clamping portion can be realized.

[0052] In addition, for the convenience of connecting the fourth connecting portion 171 to the side wall panel 71 of the vehicle body 7, please refer to Figure 1 and Figure 2 , in some embodiments, the fourth connecting portion 171 includes a U-shaped card slot for clamping with the side wall panel 71. That is to say, during installation, the U-shaped card slot is clamped on the edge portion of the side wall panel 71, and the connection between the water baffle 1 and the side wall panel 71 of the vehicle body 7 can be realized. The connection structure is simple and the connection is convenient.

[0053] In addition, for the convenience of delivering the fresh air in the side wall air duct 72 to the passenger compartment of the vehicle body 7, please refer to Figure 3 , in some embodiments, an opening 172 is provided at the position where the fifth water baffle body 17 is aligned with the side wall air duct 72 of the vehicle body 7 to deliver the fresh air conveyed in the side wall air duct 72 to the passenger compartment of the vehicle body 7. That is to say, in this embodiment, by providing the opening 172 in the water baffle 1, the side wall air duct 72 is communicated with the passenger compartment of the vehicle body 7, so that the fresh air in the side wall air duct 72 can be delivered to the passenger compartment of the vehicle body 7. Among them, Figure 3 the direction indicated by the arrow in

[0054] It can be understood that when the third water baffle body 15, the fourth water baffle body 16 and the fifth water baffle body 17 form a Z-shaped structure, the space between the fourth water baffle body 16 and the fifth water baffle body 17 is conducive to guiding the fresh air passing through the opening 172, making the fresh air in the side wall air duct 72 more conducive to entering the passenger compartment of the vehicle body 7.

[0055] In addition, in order to ensure the realization of each structure of the water baffle 1, in some embodiments, the first connecting portion 11 and the first water baffle body 13 are an integral structural member, and the second water baffle body 14, the second connecting portion 12, the third water baffle body 15, the fourth water baffle body 16 and the fifth water baffle body 17 are an integral structural member. The second water baffle body 14 is connected with a fifth connecting portion 18, and the fifth connecting portion 18 is lapped and fixed with the first water baffle body 13. That is to say, the water baffle 1 in this embodiment includes two separate structural members, and the two separate structural members are lapped and fixed at the fifth connecting portion 18 and the first water baffle body 13 to form an integral water baffle 1. In this way, it is beneficial to form the structure of each part of the water baffle 1.

[0056] It should be noted that the above-mentioned various embodiments do not limit the specific connection method of the second connecting portion 12 to the vehicle body 7 of the rail vehicle, as long as the connection between the second connecting portion 12 and the vehicle body 7 of the rail vehicle can be realized.

[0057] As Figure 2 and Figure 3 shown, in some embodiments, the second connecting portion 12 is connected to the vehicle body 7 of the rail vehicle through an elastic mounting seat 6. In the related art, the water baffle 1 is connected to the vehicle body 7 through a rigid mounting seat, while in this application, the elastic mounting seat 6 is used instead of the rigid mounting seat to connect the water baffle 1 to the vehicle body 7, which can reduce the sound bridge phenomenon and the vibration transmission of the side wall panel 71 of the vehicle body 7 to the interior of the vehicle, and suppress the sound radiation caused by the vibration of the side wall panel 71.

[0058] It should be noted that the specific structure of the elastic mounting seat 6 in this embodiment is not limited, as long as the connection between the second connecting portion 12 and the vehicle body 7 can be realized.

[0059] As Figure 4 shown, in some embodiments, the elastic mounting seat 6 includes a first profile 61, a second profile 62 and an elastomer 63. The first profile 61 is used to connect to the vehicle body 7; the second profile 62 is used to connect to the second connecting portion 12; the elastomer 63 is connected between the first profile 61 and the second profile 62. It can be understood that the first profile 61 and the second profile 62 are equivalent to skeletons. By connecting the first profile 61 and the second profile 62 to the vehicle body 7 and the second connecting portion 12 respectively, the connection reliability can be improved. At the same time, the elastomer 63 can ensure the elasticity and buffering of the elastic mounting seat 6, thereby reducing the vibration transmission.

[0060] It should be noted that the specific connection method of the first profile 61, the second profile 62 and the elastomer 63 in this embodiment is not limited, as long as the elastomer 63 can be connected to the first profile 61 and the second profile 62 respectively.

[0061] In some embodiments, the first profile 61, the elastomer 63 and the second profile 62 are integrally vulcanized to form the elastic mounting seat 6. By integrally vulcanizing to obtain the elastic mounting seat 6, the consistency of the overall structure and the structural strength of the elastic mounting seat 6 can be ensured.

[0062] In other embodiments, the elastomer 63 is nested with the first profile 61 and the second profile 62 respectively, or the elastomer 63 is bonded to the first profile 61 and the second profile 62 respectively.

[0063] In some embodiments, the elastomer 63 is respectively provided with a first buckle and a second buckle, the first profile 61 is provided with a third buckle, the second profile 62 is provided with a fourth buckle, the first buckle is buckled and connected with the third buckle, and the second buckle is buckled and connected with the fourth buckle, so as to improve the connection reliability between the elastomer 63 and the first profile 61 through the buckling connection between the first buckle and the third buckle, and improve the connection reliability between the elastomer 63 and the second profile 62 through the buckling connection between the second buckle and the fourth buckle.

[0064] In addition, the specific materials of the first profile 61, the second profile 62 and the elastomer 63 in this embodiment are not limited. In some embodiments, the first profile 61 and the second profile 62 are 6063-T5 aluminum alloy profiles respectively, and the elastomer 63 is ethylene propylene diene monomer rubber.

[0065] It should be noted that the first connecting portion 11 is used to connect with the lower floor of the vehicle body 7. The connection method of the first connecting portion 11 and the vehicle body 7 in the above various embodiments is not specifically limited. In some embodiments, the first connecting portion 11 is connected to the lower floor of the vehicle body 7 through fasteners. For example, the first connecting portion 11 is fixed to the lower floor of the vehicle body 7 by screws.

[0066] It should also be noted that in this specification, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0067] The various embodiments in this specification are described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0068] The above has introduced in detail the water baffle mounting device for rail vehicles provided by the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the present utility model.
