[0035] The technical solutions of the utility model will be clearly and completely described below in connection with the embodiments, and obviously, the described embodiments are only some of the embodiments of the utility model, but not all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0036] Referring to Figures 1-8 , a train outer wind screen fixing frame and a train outer wind screen assembly 100 provided by the utility model are understood:

[0037] In order to avoid the outer wind screen from being installed to the train, due to the shape of the shed cloth 120 not matching the shape of the train compartment, irregular air flow disturbance is formed when the train is running, thereby increasing the air resistance to the train, leading to the situation of the train operation efficiency being reduced.

[0038] According to the train outer wind screen fixing frame provided by the utility model, the two sides of the fixing frame 110 along the thickness direction of the fixing frame 110 are respectively connected to the train compartment and the shed cloth 120, and the structure of the fixing frame 110 should match the cross-sectional structure of the train compartment, so the fixing frame 110 is usually a ring-shaped frame or a U-shaped frame. Subsequently, the fixing frame 110 shown in the drawing is taken as an example to be described. Figures 1-3

[0039] The fixing frame 110 comprises a first strip plate 11, a second strip plate 12 and a third strip plate 13.

[0040] In the thickness direction of the fixing frame 110, the first strip plate 11 and the second strip plate 12 are oppositely arranged, and a first interval is left between the first strip plate 11 and the second strip plate 12, and the third strip plate 13 connected with the first strip plate 11 and the second strip plate 12 is arranged in the first interval. In this way, the first strip plate 11 and the second strip plate 12 are arranged staggered in the thickness direction of the fixing frame 110, so that the first interval forms an accommodation space for accommodating the connecting structure between the fixing frame 110, the train compartment and the shed cloth 120; in some examples, the third strip plate 13 can be integrally formed with the first strip plate 11 and the second strip plate 12, so as to maintain the overall consistency and stability of the fixing frame 110.

[0041] In the length direction of the fixing frame 110, the first strip plate 11 is configured with a plurality of first connecting portions 111, and the first connecting portions 111 are used for connecting to the train compartment, and the second strip plate 12 is configured with a plurality of second connecting portions 121, and the second connecting portions 121 are used for connecting to the shed cloth 120. In this way, the fixing frame 110 connects the shed cloth 120 and the train compartment through the first connecting portions 111 and the second connecting portions 121.

[0042] ​The second plate 12 can be directly connected to the shed cloth 120 through the second connecting part 121, or indirectly connected to the shed cloth 120. Figure 4 As shown, the second connecting part 121 is configured as a clamping groove, so that the second connecting part 121 is fixedly connected with the shed cloth 120. Figure 6 As shown, the second connecting part 121 is configured as a threaded hole or a through hole, so that the second connecting part 121 is fixedly connected with the shed cloth 120 through a screw.

[0043] It is worth noting that the shed cloth 120 is composed of a plurality of unit shed cloths 121, for example Figure 3 As shown, the cross section of each unit shed cloth 121 is U-shaped, and each unit shed cloth 121 is arranged in sequence, and a connecting clamp 122 is arranged between two unit shed cloths 121 to connect the open ends 1211 of the two adjacent unit shed cloths 121 through the connecting clamp 122, so as to form a complete shed cloth 120. That is, the part of the shed cloth 120 for connecting to the fixed frame 110 should be the open end 1211 of the unit shed cloth 121 at the edge.

[0044] In order to keep the arc-shaped part of the unit shed cloth 121120 flush with the outer contour of the fixed frame 110, so as to prevent the shed cloth 120 from generating additional wind resistance when the train is running, the first connecting part 111 and the second connecting part 121 are arranged in a staggered manner in the width direction of the fixed frame 110, and the first connecting part 111 is located on the inner circumferential side of the fixed frame 110, and the second connecting part 121 is located on the outer circumferential side of the fixed frame 110. The inner circumferential side here is the direction of the fixed frame 110 towards the inside of the train compartment, and the outer circumferential side is the direction towards the outside of the train compartment.

[0045] Therefore, the second plate 12 can be attached to the connecting clamp 122 and fixed with the connecting clamp 122 through the second connecting part 121; correspondingly, the first connecting part 111 is closer to the outer circumferential side of the fixed frame 110, so that the first connecting part 111 is located above the connecting clamp 122 and in the contour of the shed cloth 120. In this way, the first connecting part 111 and the second connecting part 121 are both located beside the shed cloth 120, so that the edges of the first plate 11 and the second plate 12 towards the outer circumferential side of the fixed frame 110 can be flush with the arc-shaped section of the shed cloth unit, thereby keeping the outer circumferential side of the fixed frame 110 flush with the edge contour of the shed cloth 120, so as to avoid the shed cloth 120 generating additional wind resistance when the vehicle is running, thereby achieving the purpose of energy saving and noise reduction.

[0046] In addition, the fixed frame 110 is usually connected with the train compartment by bolts, and the accommodation space formed by the first spacing can accommodate the head of the aforementioned bolt. Referring to Figure 5 Or Figure 6As shown, the bolt head is accommodated in the first interval, so that the bolt forms a clearance to the canopy cloth 120 along the thickness direction of the fixing frame 110, thereby keeping the first connecting portion 111 flush with the canopy cloth 120 in the width direction of the fixing frame 110.

[0047] It can be understood that the second connecting portion 121 is fixed with the open end of the canopy cloth unit, the first connecting portion 111 is staggered with the second connecting portion 121 in the width direction of the fixing frame 110, and the structure for being accommodated with the train compartment bolt in the first interval can ensure that the fixing frame 110 and the canopy cloth 120 are flush in the edge profile. On the one hand, the wind resistance during train operation can be reduced, and on the other hand, when the adjacent train compartments are close to each other during train operation, the fixing frame 110 and the canopy cloth 120 can be squeezed to provide additional fixing effect, so that the squeeze bending strength of the canopy cloth 120 is higher, the structural stability is better, and the wind resistance and anti-swing ability are better. In addition, the outer wind barrier and the vehicle body profile are matched, and the overall appearance is beautiful.

[0048] Further, the side of the first plate 11 away from the second plate 12 is also provided with a first sealing strip 112, which is used to fit with the train compartment to seal the gap between the train compartment and the first plate 11, thereby improving the sealing effect between the fixing frame 110 and the train compartment. In this way, good air tightness and waterproofness between the canopy cloth and the train compartment can be ensured.

[0049] In some preferred embodiments, the first plate 11 is formed with a sealing groove 113 in the direction toward the second plate 12, the sealing groove 113 is formed in the first interval and is used to clamp the first sealing strip 112, so that the first sealing strip 112 is built into the sealing groove 113,

[0050] In order to better understand the embodiments of the present application, two embodiments will be described below.

[0051] Reference Figures 4-5 The first embodiment is understood.

[0052] The first connecting portion 111 is a through hole, and the third bolt 18 is arranged through the first connecting portion 111 to fix the first plate 11 with the train compartment through the bolt. The second connecting portion 121 is a clamping groove. Specifically, the second plate 12 is bent to extend a clamping plate 1211 parallel to itself, and the clamping groove is defined between the clamping plate 1211 and the second plate 12, and the distance between the second plate 12 and the clamping plate 1211 is less than the thickness of the open end 1211 of the canopy cloth unit.

[0053] The clamping groove is fixed between the clamping groove and the shed cloth by clamping process. Specifically, the open end 1211 of the shed cloth unit can be inserted into the clamping groove defined between the second strip 12 and the clamping plate 1211. Since the distance between the second strip 12 and the clamping plate 1211 is less than the thickness of the open end 1211 of the shed cloth unit, when the shed cloth 120 is inserted into the clamping groove, it will be subjected to a certain extrusion force, thereby being firmly fixed in the clamping groove.

[0054] Therefore, the open torque wrench can be used to install or disassemble the shed cloth 120 and the clamping groove. The open torque wrench can accurately control the clamping force to ensure that the shed cloth 120 is firmly clamped in the clamping groove, and at the same time, will not cause damage to the shed cloth 120 during installation. When disassembly is required, the shed cloth 120 can be easily removed from the clamping groove by using the open torque wrench in reverse, which is convenient and fast.

[0055] In some preferred embodiments, a sawtooth structure 1212 is provided in the clamping groove, as shown in Figure 4 By the sawtooth structure 1212, the shed cloth 120 clamped and fixed in the clamping groove can have a better engagement and fixing effect with the sawtooth structure 1212, and the shed cloth 120 can be clamped and fixed at different angles and in different directions with the sawtooth structure 1212.

[0056] Reference Figures 6-8 The second embodiment is understood.

[0057] The first connecting part 111 is a through hole, and the second connecting part 121 is a threaded hole. Here, the bolt penetratingly provided in the first connecting part 111 is defined as a first bolt 16, and the bolt provided in the second connecting part 121 is defined as a second bolt 17. The threaded section of the first bolt 16 is used for screwing to the carriage, and the nut is located in the first interval between the first strip 11 and the second strip 12. The threaded section of the second bolt 17 is screwed into the connecting clamp 122 and the second connecting part 121.

[0058] The first strip 11 and the second strip 12 are also connected with a reinforcing plate 14, which is located below the third strip 13, so as to surround the third strip 13, the first strip 11 and the second strip 12 to form a cavity. In this way, the fixed frame 110 configured as a hollow pipe structure has better structural strength.

[0059] In addition, the fixed frame 110 also clamps a decorative strip plate. The decorative strip plate 15 is clamped between the first strip 11 and the second strip 12 and is located on the outer circumferential side of the fixed frame 110. After the decorative strip plate is clamped with the first strip 11 and the second strip 12, the first interval is closed, thereby shielding the bolt and the first interval, and improving the aesthetic effect of the fixed frame 110 and the shed cloth 120.

[0060] In the present example, the first strip 11 is configured with a first clamping groove 114 away from one side of the curtain 120, and the third strip 13 is configured with a second clamping groove 131 towards the outer circumferential side of the fixed frame 110; correspondingly, referring to Figure 8 It is understood that the cross section of the decorative strip is L-shaped, and one end of the L-shaped structure extends out the first protruding block 151, and the other end extends out the second protruding block 152; referring to Figure 6 and Figure 7 As shown, the first protruding block 151 is clamped and matched with the first clamping groove 114, and the second protruding block 152 is matched with the second clamping groove 131, so that the decorative strip blocks the first gap after being matched with the fixed frame 110.

[0061] In some preferred examples, the decorative strip can be made of EPDM material using an extrusion vulcanization molding process, which is simpler, so that the surface of the fixed frame 110 is decorated by the decorative strip, and thus there is no need to spray protective paint on the surface of the vehicle outer windshield, thereby reducing the manufacturing cost.

[0062] In some preferred examples, the second clamping groove 131 is configured as a trapezoidal notch as shown in Figure 6 The trapezoidal notch has better structural strength. Of course, the first clamping groove 114 can also be configured as a trapezoidal notch, which will not be described in detail here.

[0063] In the present example, the first sealing strip 112 is a rubber strip with a semicircular cross section, and the sealing groove 113 is formed below the third strip 13, so that the first sealing strip 112 is clamped inside.

[0064] In addition, the second strip 12 is also provided with a second sealing strip towards one side of the curtain 120, which is attached to the connecting clip 122. The second sealing strip seals and fills the gap between the curtain 120 and the fixed frame 110, so as to improve the sealing effect and waterproof effect between the fixed frame 110 and the curtain 120.

[0065] In the above two specific examples, the cross section of the fixed frame 110 formed by the first strip 11, the second strip 12 and the third strip 13 is larger than that of a single strip structure, so the structural strength of the fixed frame 110 is better.

[0066] Based on any one of the above embodiments, the fixed frame 110 is an integral molding structure. The fixed frame 110 is produced as a straight strip, and then a multi-angle integral molding rolling bending process is adopted, in which a large section profile is verified once, and a plurality of points are compensated, so that the fixed frame 110 is rolled into a ring-shaped frame body, and then the two ends of the fixed frame 110 after rolling are welded to form the aforementioned ring-shaped frame body.

[0067] According to the train outer windshield assembly 100 of the present application, referring to Figures 1-3It is understood that the fixed frame 110 is arranged on both sides of the shed cloth 120, including the shed cloth 120 and the fixed frame 110 described in any one of the foregoing embodiments.

[0068] The above description is only preferred embodiments of the present application, and it should be understood that the present application is not limited to the forms disclosed herein, and should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concepts described herein by the above teachings or related art or knowledge. Any modification and change made by those skilled in the art without departing from the spirit and scope of the present application shall be within the protection scope of the claims of the present application.
