Description

Technical Field

[0001] This application relates to rail vehicle technology, and more particularly to a windshield and a rail vehicle. Background Technology

[0002] Rail vehicles consist of multiple carriages coupled together, such as Figures 1 to 3 As shown, an outer windshield 1 and an inner windshield 2 connect the ends of adjacent carriages, providing safety protection for passengers passing between them. The outer windshield 1 and inner windshield 2 of adjacent carriages are connected by a connecting frame 3. The two connecting frames 3 are connected together and respectively connected to the inner and outer windshields of the two carriages. When the vehicle is running in a low-temperature environment, a large amount of condensation will appear on the inner surface 31 of the connecting frame of the windshield. In extremely low temperatures, the condensation will freeze, affecting the safety of passengers passing through.

[0003] To achieve sufficient connection strength while maintaining a low weight, the inner windshield connecting frame is typically made of aluminum alloy. The outer side of the connecting frame is in contact with the cold outside air. Due to the thermal bridging effect of the metal, both the inner and outer surfaces of the connecting frame are at low temperatures. Because the air inside the car is relatively humid, a large amount of condensation will form on the surface of the connecting frame, and it may even freeze.

[0004] To address the issue of condensation, the common approach in this field is to spray an anti-condensation topcoat onto the object's surface. However, under conditions of significant temperature differences between the inside and outside of the vehicle and high humidity inside, the effectiveness of the anti-condensation topcoat is poor, and a large amount of condensation still occurs. Other solutions involve adding a metal frame shell to the surface of the connecting frame, but this still cannot prevent the metal thermal bridge effect, and condensation also occurs on the metal frame shell, and in the interlayer between the metal frame shell and the connecting frame. Summary of the Invention

[0005] To address one of the aforementioned technical deficiencies, this application provides a windshield and a rail vehicle.

[0006] According to a first aspect of the embodiments of this application, a windshield is provided, including: two connecting frames, an inner windshield and an outer windshield; the inner windshield is located inside the outer windshield, and the inner windshield and the outer windshield are disposed on the sides of the connecting frames; the two connecting frames are connected together;

[0007] Also includes:

[0008] The cold-proof layer is laid on the inner surface of the connecting frame;

[0009] The overlay is laid on the surface of the insulation layer; the overlay is made of non-metallic materials.

[0010] According to a second aspect of the embodiments of this application, a rail vehicle is provided, including: a windshield as described above.

[0011] The technical solution provided in this application uses a non-metallic covering layer to block the thermal bridging effect of the connecting frame, ensuring that the surface temperature of the non-metallic material is comparable to the interior temperature of the vehicle compartment. When the vehicle is traveling in a low-temperature environment, the surface temperature of the covering layer will not be too low, thereby reducing the generation of condensation. Furthermore, the cold-proof layer installed between the covering layer and the connecting frame further isolates heat conduction between the connecting frame and the covering layer, reducing the transfer of cold energy to the covering layer and ensuring that the temperature of the covering layer is approximately the same as the interior temperature of the vehicle compartment.

[0028] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0029] This embodiment provides a windshield that can be applied to rail vehicles and is installed between two adjacent carriages. The windshield includes two connecting frames 3, which are connected together. An outer windshield 1 and an inner windshield 2 are provided on the sides of the connecting frames 3, with the outer windshield 1 located outside the inner windshield 2. The inner windshield is installed between the end doors of two adjacent carriages, and the outer windshield is installed on the outer contour of the end wall of the car body. The space enclosed by the inner windshield 2 and the connecting frames 3 serves as a central aisle, through which passengers pass to enter the adjacent carriages.

[0030] The inner surface of the connecting frame 3 is covered with a cold-proof layer, which can be made of cold-proof materials commonly used in this field. A covering layer is cut into the surface of the cold-proof layer, and the covering layer is made of non-metallic materials.

[0031] The technical solution provided in this embodiment uses a non-metallic covering layer to block the thermal bridging effect of the connecting frame, ensuring that the surface temperature of the non-metallic material is comparable to the interior temperature of the vehicle compartment. When the vehicle is traveling in a low-temperature environment, the surface temperature of the covering layer will not be too low, thus reducing condensation. Furthermore, the cold-resistant layer placed between the covering layer and the connecting frame further isolates heat conduction between them, reducing the transfer of cold energy to the covering layer and keeping its temperature close to the interior temperature of the vehicle compartment.

[0032] Based on the above technical solution, the cold protection layer can be laid only on the inner surface 31 of the connecting frame 3, or it can extend to the side of the connecting frame 3, that is, the side with the inner windshield 2 and the outer windshield 1.

[0033] This embodiment provides one implementation method, such as... Figure 4 As shown, the covering layer is a fiberglass layer 41. A topcoat is sprayed on the surface of the fiberglass layer 41. The color of the topcoat is the same as the color of the connecting frame 3 so that the appearance of the fiberglass layer 41 is consistent with that of the connecting frame 3.

[0034] A cold-proof layer 44 is laid on the inner surface of the connecting frame 3, with one end extending to the joint of the two connecting frames 3, and the other end bent and extending to the side of the connecting frame 3 away from the other connecting frame 3. A fiberglass layer 41 is laid on the surface of the cold-proof layer 44, with one end extending to the corresponding position of the two connecting frames 3, and the other end bent and extending to the side of the connecting frame 3 away from the other connecting frame 3. For example, the end of the cold-proof layer 44 is flush with the end of the fiberglass layer 41. The same ends of the cold-proof layer 44 and the fiberglass layer 41 are connected to the connecting frame 3 by threaded fasteners 51 or rivets.

[0035] Each connecting frame 3 has a corresponding surface covered with an insulating layer 44 and a fiberglass layer 41. A rubber seal 45 is provided between the mating surfaces of the fiberglass layer 41 and the insulating material 44 on the surfaces of the two connecting frames 3. Specifically, the ends of the insulating layer 44 and the fiberglass layer 41 are provided with rubber seals 45. The two rubber seals 45 are mated together and pressed against each other to achieve a seal, preventing moisture from entering the gaps between the fiberglass layer 41 and the insulating material 44, thus preventing condensation.

[0036] This embodiment also provides an implementation method, such as... Figure 5 As shown, the covering layer is a canopy 42, and the material of the canopy 42 is the same as that of the inner windshield 2 or the outer windshield 1. The cold-proof layer 44 covers the inner surface 31 of the connecting frame and extends from the junction of the two connecting frames 3 to the side of the connecting frame 3. The canopy 42 is laid on the surface of the cold-proof layer 44 and extends from the corresponding ends of the two connecting frames 3 to the side of the connecting frame 3.

[0037] The cold-proof layer 44 can be glued to the surface of the connecting frame 3, for example, using traceless adhesive. The canopy 42 can be glued to the surface of the cold-proof layer 44.

[0038] Or, such as Figure 6 As shown, the tarpaulin 42 and the insulation layer 44 are connected together by Velcro, and the insulation layer 44 and the connecting frame 3 are connected together by Velcro 48. Specifically, the Velcro 48 is fixed to the surface of the connecting frame 3 by threaded fasteners or rivets, or it can be glued to the surface of the connecting frame 3. Corresponding Velcro 48s are sewn or glued to one side of the insulation layer 44 to bond the insulation layer 44 to the connecting frame 3. Velcro 48s are also provided on the other side of the insulation layer 44 and the tarpaulin 42, and the insulation layer 44 and the tarpaulin 42 are connected by Velcro 48.

[0039] This embodiment also provides an implementation method, which is consistent with... Figure 5 and Figure 6 What they have in common is that the covering layer is a canopy 42, and one canopy 42 is set for each connecting frame 3. For example... Figure 7 As shown, the difference is that the ends of the cold-proof layer 44 and the canopy 42 are fixed to the connecting frame 3 by threaded fasteners or rivets.

[0040] Furthermore, rubber strips 46 are respectively provided on the mating surfaces of the cold-proof layers 44 on the two connecting frames 3. The same end of the cold-proof layers 44 and the canopy 42 is connected to the connecting frame 3 by threaded fasteners or rivets. The rubber strips 46 are provided with flanges 461, which are located on the surface of the canopy 42 to cover the threaded fasteners 51 or rivets. When the cold-proof layers 44 are mated, the two rubber strips 46 are squeezed and sealed against each other.

[0041] This embodiment also provides an implementation method, such as... Figure 8 As shown, the covering layer also uses a tarpaulin 42, with one tarpaulin 42 corresponding to each connecting frame 3. The tarpaulin 42 is laid on the surface of the cold-proof layer 44. Two tarpaulins 42 are connected by a zipper 47. A fabric clamping frame is provided on the side of the connecting frame 3, and the end of the tarpaulin 42 extending to the side of the connecting frame 3 is connected to the fabric clamping frame on the side of the connecting frame by a zipper.

[0042] like Figure 9 As shown, with Figure 8 The difference is that a sheet of fabric 42 is used to cover the surfaces of the two connecting frames 3, and the end of the sheet of fabric 42 extending to the side of the connecting frame 3 is connected to the fabric clamping frame on the side of the connecting frame 3 by a zipper 47.

[0043] Based on the above technical solutions, this embodiment also provides an implementation method, such as... Figure 10 As shown, the covering layer is felt 43, which is adhered to the surface of the cold-proof layer 44. The felt 43 can also block the metal thermal bridge effect of the connecting frame 3 and prevent water vapor from adhering to the low-temperature connecting frame 3 and forming condensation. Figure 10 Only felt 43 is shown in the image.

[0044] Alternatively, the felt 43 and the cold-proof layer 44 are integrated, and the inner part of the felt 43 serves as a cold-proof layer with anti-welding function.

[0045] The outer surface coating of felt 43 ensures surface sealing and prevents moisture from entering the interior of the felt to avoid condensation from contacting the surface of the metal connecting frame. The thickness of felt 43 can be 2mm, and it is bonded to the surface of connecting frame 3 with adhesive.

[0046] The above-mentioned solution provided in this embodiment lays a cold-proof layer 44 on the surface of the connecting frame 3, followed by a non-metallic covering layer. This effectively isolates the metal thermal bridge effect and prevents the generation of condensation on the vehicle's interior surface. Different solutions can be selected for different needs. The overall solution has a small thickness and does not affect the passageway dimensions. All solutions have a beautiful surface appearance and good effect. They can be used for both factory-made and newly manufactured vehicles. The operation and connection methods are simple, and it is easy to disassemble and replace. This solution can effectively prevent the generation of condensation on the vehicle's interior. This solution can also be applied to all vehicle surfaces where condensation occurs, providing a new approach for subsequent optimization of rail vehicle structures.

[0047] Based on the above technical solutions, this embodiment also provides a rail vehicle, including the windshield provided in any of the above contents. The rail vehicle provided in this embodiment has the same technical effect as the windshield described above.
