[0028] Unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] The interior of the vehicle body of a rail vehicle is mainly composed of the floor, side walls, roof, etc. Among them, the storage compartment is usually under the floor or on the side of the side wall away from the passenger cabin. The floor and the side wall are usually spliced, so there are gaps. When water seeps into the storage compartment, it may cause damage to the equipment or lines in the storage compartment, affecting driving safety.

[0030] In order to solve the above technical problems, the present application discloses a waterproof structure for the connection between the floor of a rail vehicle and the side wall of the vehicle body to prevent water from seeping into the above gap, thereby ensuring that the equipment and lines in the storage bin are not damaged and ensuring the driving safety of the rail vehicle.

[0031] The following is attached to the instruction manual Figure 1 , 2 , an embodiment of the present application is described in detail. Figure 1 It is a front view of a waterproof structure for the connection between the floor and the side wall of a rail vehicle shown in an embodiment of the present application; Figure 2It is a structural schematic diagram of the actual application of the waterproof structure at the connection between the railway vehicle floor and the vehicle body side wall shown in the embodiment of the present application.

[0032] See also Figure 1 , Figure 2 The embodiment of the present application discloses a waterproof structure for the connection between the floor of a rail vehicle and the side wall of the vehicle body, including: a waterproof filler 11, a waterproof connector 12 and a sealing component 13.

[0033] The waterproof filler 11 in the present application can be filled in the joint formed between the wall 20 and the floor 30 of the vehicle, and the waterproof filler is in close contact with the wall and the floor respectively, so that the part above the filler has a supporting force, reduces vibration and noise, and increases the stability of the entire waterproof structure.

[0034] In the embodiment of the present application, the waterproof filler can be a waterproof and fireproof sealing material, which can be a ceramic fiber felt. Ceramic fiber felt as a waterproof filler has low cost and is easy to construct. Ceramic fiber felt is resistant to high temperature and corrosion, is an inorganic material, does not burn, does not produce harmful gases, and can isolate and protect well.

[0035] In the embodiment of the present application, the waterproof connector 12 may include a cover portion 121 and a water retaining portion 122, wherein the water retaining portion is formed by the cover portion extending upward. The cover portion 121 covers the aforementioned filler and the joint to provide a sealing effect. The cover portion 121 is bonded to the upper surface of the floor 30.

[0036] The water retaining part 122 is used to configure the water retaining height. The height of the water retaining part 122 is the same as the height of the water retaining part to be set, and can be set according to actual needs. The water retaining part is set parallel to the wall, rather than obliquely, in order to make the entire structure more stable and avoid structural deformation under the action of gravity.

[0037] The sealing component 13 is disposed between the water retaining portion 122 and the wall 20, and can cover the upper surface of the waterproof filler 11 in contact with the sealing component, thereby playing a sealing role.

[0038] In the embodiment of the present application, the sealing component 13 is respectively bonded to the waterproof connector 12 and the wall 20 to form a completely sealed structure.

[0039] Among them, one end of the sealing component 13 is bonded to the wall 20, and the other end is bonded to the waterproof connector 12, so that the waterproof connector 12, the sealing component 13 and the waterproof filler 11 completely seal the gap, so that water cannot penetrate into the storage compartment through the gap.

[0040] In the embodiment of the present application, the waterproof connector 12 may be a right-angle aluminum profile or angle aluminum. The cover portion 121 of the waterproof connector 12 may be bonded to the floor so that water cannot penetrate into the gap between the floor and the waterproof connector.

[0041] In actual use, the sealing component can be a sealant. The sealant is used to achieve bonding with the wall 20, the water retaining portion 122 of the waterproof connector, and the upper surface of the waterproof filler. If the gap is completely filled with sealant, the construction is difficult and the material cost is high. At the same time, the sealant is easy to leak into the storage compartment, thereby affecting the normal operation of the equipment and lines. Therefore, the waterproof filler used in the waterproof structure in the embodiment of the present application not only provides sufficient support, but also saves costs.

[0042] In another embodiment, the cover portion 121 may extend a support portion (not shown) toward the wall 20, and the support portion may be inserted into a portion of the waterproof filler, so that the waterproof filler between the sealing component 13 and the support portion has better support force, making the sealing component 13 more stable. In this way, the longitudinal section of the waterproof connector is T-shaped.

[0043] In some embodiments, another downward supporting component (not shown in the figure) can be extended from the covering portion 121 toward the storage compartment. When no equipment or cables are installed under the gap, the downward supporting component can be directly connected to the bottom of the storage compartment, so that the waterproof filler can be placed between the other supporting component and the wall, and better supporting force can be provided.

[0044] The present application is applied to rail vehicles, and the structure is applied to the gap area between the floor and the wall in the vehicle compartment. The lower part of the structure is filled with waterproof filler, and the two sides of the waterproof filler are in close contact with the floor and the wall respectively. The fireproof connector is bonded to the upper surface of the floor, and the sealing component is applied to the upper surface of the waterproof filler between the waterproof connector and the wall to form a complete sealing structure to achieve a sealing effect.

[0045] The waterproof structure can effectively prevent water from penetrating into the gap between the floor and the side wall of the rail vehicle, and has good waterproof effect. The waterproof capacity meets the requirements and is practical and reliable. The construction is simple, and a large amount of fireproof sealing materials are filled to reduce the use of sealants and reduce costs. The surface of the sealant is simple and smooth, and the appearance is beautiful.

[0046] The scheme of the present application has been described in detail above with reference to the accompanying drawings. In the above embodiments, the descriptions of the various embodiments have their own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

In addition, it can be understood that the steps in the method of the embodiment of the present application can be adjusted in order, merged and deleted according to actual needs, and the modules in the device of the embodiment of the present application can be merged, divided and deleted according to actual needs.

[0047] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
