Description

Technical Field

[0001] The present application relates to rail vehicle technology, and in particular to a windshield and a rail vehicle. Background Art

[0002] Rail vehicles consist of multiple carriages connected together, such as Figures 1 to 3 As shown, an outer windshield 1 and an inner windshield 2 are connected between the ends of adjacent carriages to provide safety protection for passengers passing between adjacent carriages. The outer windshield 1 and the inner windshield 2 of the adjacent carriages are connected by a connecting frame 3, and 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 traveling in a low-temperature environment, a large amount of condensed water will appear on the inner surface 31 of the connecting frame of the windshield. When the temperature is extremely low, the condensed water will freeze and affect the safety of passengers passing.

[0003] In order to meet the connection strength requirements and have a small weight, the inner windshield connection frame is usually made of aluminum alloy. The outer side of the connection frame is in contact with the external cold air. Through the metal thermal bridge effect, the surface of the connection frame inside the car and the surface outside the car are both in a low temperature state. Since the air in the car is relatively humid, a large amount of condensation water will be generated on the surface of the connection frame, and even ice will form.

[0004] In order to solve the problem of condensation, the art generally adopts the solution of spraying anti-condensation topcoat on the surface of the object. However, when the temperature difference between the inside and outside of the car is large and the humidity inside the car is high, the effect of the anti-condensation topcoat is not good, and there is still a lot of condensation. Some people add a metal frame shell on the surface of the connection frame, but the metal thermal bridge effect cannot be blocked. Condensation water will also be generated on the metal frame shell, and condensation water will be generated in the interlayer between the metal frame shell and the connection frame. Summary of the invention

[0005] In order to solve one of the above-mentioned technical defects, a windshield and a rail vehicle are provided in an embodiment of the present application.

[0006] According to a first aspect of an embodiment of the present application, there is provided a windshield, comprising: two connecting frames, an inner windshield and an outer windshield; the inner windshield is located on the inner side of the outer windshield, and the inner windshield and the outer windshield are arranged on the side of the connecting frame; the two connecting frames are connected;

[0007] Also includes:

[0008] A cold-proof layer, laid on the inner surface of the connection frame;

[0009] The covering layer is laid on the surface of the cold-proof layer; the covering layer is made of non-metallic material.

[0010] According to a second aspect of an embodiment of the present application, there is provided a rail vehicle, comprising: a windshield as described above.

[0011] The technical solution provided in the embodiment of the present application uses a covering layer made of non-metallic material to block the metal thermal bridge effect of the connection frame, so that the surface temperature of the non-metallic material is equivalent to the temperature inside the vehicle. When the vehicle is driving in a low-temperature environment, the temperature of the surface of the covering layer will not be too low, thereby reducing the generation of condensed water. The cold-proof layer set between the covering layer and the connection frame can further isolate the heat conduction between the connection frame and the covering layer, reduce the conduction of cold to the covering layer, and make the temperature of the covering layer similar to the temperature inside the vehicle.

[0028] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0029] The present embodiment provides a windshield, which can be used in a rail vehicle and is arranged 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 arranged on the side of the connecting frame 3, and the outer windshield 1 is located on the outer side of the inner windshield 2. The inner windshield is installed between the end doors of the two adjacent carriages, and the outer windshield is installed at the outer contour of the end wall of the vehicle body. The space enclosed by the inner windshield 2 and the connecting frame 3 is used as a middle aisle, and passengers pass through the middle aisle to enter the adjacent carriage.

[0030] The inner surface of the connection frame 3 is paved with a cold-proof layer, which can be made of cold-proof materials commonly used in the art. The surface of the cold-proof layer is provided with a covering layer, which is made of non-metallic materials.

[0031] The technical solution provided in this embodiment uses a covering layer made of non-metallic material to block the metal thermal bridge effect of the connection frame, so that the surface temperature of the non-metallic material is equivalent to the temperature inside the vehicle. When the vehicle is driving in a low-temperature environment, the temperature of the surface of the covering layer will not be too low, thereby reducing the generation of condensed water. The cold-proof layer set between the covering layer and the connection frame can further isolate the heat conduction between the connection frame and the covering layer, reduce the conduction of cold to the covering layer, and make the temperature of the covering layer similar to the temperature inside the vehicle.

[0032] On the basis of the above technical solution, the cold-proof layer can be laid only on the inner surface 31 of the connecting frame 3, or can be extended to the side of the connecting frame 3, that is, the side where the inner windshield 2 and the outer windshield 1 are provided.

[0033] This embodiment provides an implementation method. Figure 4 As shown, the covering layer is a glass fiber reinforced plastic layer 41 , and a topcoat is sprayed on the surface of the glass fiber reinforced plastic layer 41 . The color of the topcoat is the same as the color of the connection frame 3 , so that the appearance of the glass fiber reinforced plastic layer 41 looks consistent with that of the connection frame 3 .

[0034] The cold-proof layer 44 is laid on the inner surface of the connection frame 3, one end of which extends to the position where the two connection frames 3 are butted, and the other end is bent and extended to the side of the connection frame 3 away from the other connection frame 3. The glass fiber reinforced plastic layer 41 is laid on the surface of the cold-proof layer 44, one end of which extends to the position corresponding to the two connection frames 3, and the other end is bent and extended to the side of the connection frame 3 away from the other connection frame 3. For example, the end of the cold-proof layer 44 is flush with the end of the glass fiber reinforced plastic layer 41. The same end of the cold-proof layer 44 and the glass fiber reinforced plastic 41 is connected to the connection frame 3 by a threaded fastener 51 or a rivet.

[0035] The surface of each connection frame 3 is correspondingly paved with a cold-proof layer 44 and a glass fiber reinforced plastic layer 41. A rubber seal 45 is provided between the butting surfaces of the glass fiber reinforced plastic layer 41 and the cold-proof material 44 on the surfaces of the two connection frames 3. Specifically, rubber seals 45 are provided at the ends of the cold-proof layer 44 and the glass fiber reinforced plastic layer 41, and the two rubber seals 45 are butted and squeezed against each other to achieve sealing, so that the water vapor in the car cannot enter the gap between the glass fiber reinforced plastic layer 41 and the cold-proof material 44, thereby preventing condensation water from being generated.

[0036] This embodiment also provides an implementation method. Figure 5 As shown, the covering layer is a shed cloth 42, and the material of the shed cloth 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 connection frame, and extends from the position where the two connection frames 3 are connected to the side of the connection frame 3. The shed cloth 42 is laid on the surface of the cold-proof layer 44, and extends from the corresponding ends of the two connection frames 3 to the side of the connection frame 3.

[0037] The cold-proof layer 44 can be bonded to the surface of the connection frame 3 by glue, for example, by using traceless glue. The awning cloth 42 can be bonded to the surface of the cold-proof layer 44 by glue.

[0038] Or, if Figure 6 As shown, the awning cloth 42 and the cold-proof layer 44 are connected together by nylon buckles, and the cold-proof layer 44 and the connection frame 3 are connected together by nylon buckles 48. Specifically, the nylon buckles 48 are fixed to the surface of the connection frame 3 by threaded fasteners or rivets, and can also be glued to the surface of the connection frame 3. The corresponding nylon buckles 48 are sewn or glued on one side of the cold-proof layer 44, so that the cold-proof layer 44 is bonded to the connection frame 3 by the buckles. The other side of the cold-proof layer 44 and the awning cloth 42 are also provided with corresponding nylon buckles 48, and the cold-proof layer 44 and the awning cloth 42 are connected by the nylon buckles 48.

[0039] This embodiment also provides an implementation method. Figure 5 and Figure 6 The same thing is that the covering layer is a awning cloth 42, and one awning cloth 42 is correspondingly arranged for one connection frame 3. Figure 7 As shown, the difference is that the cold-proof layer 44 and the ends of the awning cloth 42 are fixed to the connecting frame 3 by threaded fasteners or rivets.

[0040] Furthermore, the butt joint surfaces of the cold-proof layers 44 on the two connection frames 3 are respectively provided with rubber strips 46, and the same end of the cold-proof layer 44 and the awning cloth 42 is connected to the connection frame 3 through a threaded fastener or a rivet. The rubber strip 46 is provided with a flange 461, and the flange 461 is located on the surface of the awning cloth 42 to cover the threaded fastener 51 or the rivet. When the cold-proof layers 44 are butt jointed, the two rubber strips 46 are squeezed and sealed against each other.

[0041] This embodiment also provides an implementation method. Figure 8 As shown, the covering layer also uses a awning cloth 42, and one awning cloth 42 is correspondingly provided for one connecting frame 3, and the awning cloth 42 is laid on the surface of the cold-proof layer 44. The two awning cloths 42 are connected by a zipper 47. A cloth clamping frame is provided on the side of the connecting frame 3, and the end of the awning cloth 42 extending to the side of the connecting frame 3 is connected to the cloth clamping frame on the side of the connecting frame by a zipper.

[0042] like Fig. 9 As shown, Figure 8 The difference is that a shed cloth 42 is used to cover the surfaces of the two connection frames 3 , and the end of the shed cloth 42 extending to the side of the connection frame 3 is connected to the cloth clamping frame on the side of the connection frame 3 through a zipper 47 .

[0043] Based on the above technical solution, this embodiment also provides an implementation method, such as Fig.10 As shown, the covering layer is a felt 43, which is pasted on the surface of the cold-proof layer 44. The felt 43 can also block the metal thermal bridge effect of the connection frame 3, and can prevent water vapor from adhering to the low-temperature connection frame 3 to form condensed water. Fig.10 Only the felt 43 is shown.

[0044] Alternatively, the felt 43 and the cold-proof layer 44 are provided integrally, and the inner portion of the felt 43 serves as the cold-proof layer and has a welding-proof function.

[0045] The outer surface coating of the felt 43 ensures the surface sealing and prevents water vapor from entering the felt to avoid contact with the surface of the metal connection frame to produce condensed water. The felt 43 can be 2mm thick and is bonded to the surface of the connection frame 3 by glue.

[0046] The above-mentioned scheme provided in this embodiment is to lay a layer of cold-proof layer 44 on the surface of the connecting frame 3 in sequence, and then lay a layer of non-metallic covering layer, which can effectively isolate the metal thermal bridge effect and prevent the generation of condensation water on the surface of the vehicle. Different schemes can be selected for coating according to different needs. The overall scheme has a small thickness and does not affect the passing size of the through-channel. The surface appearance quality of all schemes is beautiful and the effect is good. It can be used for both factory-made and new vehicles. The operation and connection methods are simple, easy to disassemble and replace, and can effectively prevent the generation of condensation water in the vehicle. This scheme can also be used for coating the surfaces where condensation water is generated on all vehicles, providing new ideas for the subsequent optimization of rail vehicle structures.

[0047] On the basis of the above technical solutions, this embodiment further provides a rail vehicle, including a windshield provided by any of the above contents. The rail vehicle provided by this embodiment has the same technical effect as the above windshield.
