DETAILED DESCRIPTION

[0033] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 and Fig.13 , Fig.14 as well as Fig.15 As shown, the present invention provides a technical solution: a novel high-speed train outer windshield structure, including a spoiler structure, wherein the spoiler structure is installed on a train 20, the train 20 includes at least two carriages, and the train 20 is installed on the top surface of the connection between the two carriages, and each carriage is provided with two spoiler structures, which are symmetrically distributed in an "eight" shape about the carriage, and the spoiler structure is an arc-shaped plate structure, matching the arc surface of the outer frame of the train 20, and the spoiler structure is at the top of the train 20 to reduce the aerodynamic noise in the crew room area.

[0035] Taking the train route [Shanghai-Beijing] as an example, the maximum operating speed is 350 km / h. Table 1 shows the total noise value of the crew room area when the train runs at a constant speed of 350 km / h, with and without spoilers installed on the upper part of the outer windshield. The measurement points include: the center of the crew room, the middle aisle, the windshield, the platform and the middle of the acoustic cavity.

[0036] Table 1 Total noise level in the crew room (unit: dB)

[0037]

[0038] As can be seen from Table 1, for the noise at the positions of the crew compartment, the middle aisle, the windshield, the vestibule, and the middle part of the acoustic cavity where spoiler plates are installed on the upper part of the external windshield at the end of the multiple unit train, it is slightly less than the situation without installing spoiler plates. (And this patent will also explain that after installing spoiler plates on the upper part of the external windshield of the multiple unit train, the influence on the total noise value at the positions of the crew compartment and the middle part of the acoustic cavity is more obvious in terms of the optimization effect compared with the aerodynamic noise influence in other areas / positions of the vehicle).

[0039] Refer to the appendix Fig.14 and Fig.15 As shown, before and after the rectification of the external windshield, the significant frequency bands of the noise at the position of the crew compartment of the multiple unit train are all in the 31.5 - 50 Hz frequency band, and the peak frequency band is 37 Hz. However, after installing spoiler plates on the upper part of the external windshield of the train, the noise at the 40 Hz frequency band at the position of the crew compartment is significantly reduced by about 5 dB. In addition, installing spoiler plates on the upper part of the external windshield also has a certain degree of reduction effect on the noise in the high - frequency part.

[0040] Embodiment 2: Refer to the appendix Figures 2 to 10 As shown, on the basis of Embodiment 1, in order to realize the adjustment of the height of the spoiler plate, the spoiler structure includes a spoiler base plate 1 and an extension buckle plate 2 sleeved on the top end of the spoiler base plate 1. There are two groups of adjustment components between the spoiler base plate 1 and the extension buckle plate 2 for adjusting the vertical distance between the spoiler base plate 1 and the extension buckle plate 2, changing the overall height of the spoiler structure. The spoiler base plate 1 has an arc - plate structure with a "convex" - shaped end face, and the extension buckle plate 2 has an annular - plate structure with a "匚" - shaped end face. The two groups of adjustment components are respectively distributed at both ends of the spoiler base plate 1; the adjustment component includes an installation groove 3, a perforation 4, a wire sleeve 5, a rubber connecting block 6, an adjustment screw 7, a limit turning handle 8, an installation port 9, a limit piece 10, and a dial 11. The installation groove 3 is opened at the end of the spoiler base plate 1. The installation groove 3 is a "convex" - shaped groove. The perforation 4 is opened on the top surface of the installation groove 3. The perforation 4 is a square hole. The wire sleeve 5 is inserted into the perforation 4. The wire sleeve 5 is a square column, and the inner ring opening of the wire sleeve 5 is a circular thread groove. The rubber connecting block 6 is fixed between the bottom surface of the top plate of the extension buckle plate 2 and the top surface of the wire sleeve 5. The adjustment screw 7 is inserted and screwed into the circular thread groove of the wire sleeve 5. The limit piece 10 is fixed on the inner wall of the installation groove 3. The installation port 9 is a circular hole. The installation port 9 is opened on the surface of the limit piece 10. The limit turning handle 8 is rotatably connected inside the installation port 9. The limit turning handle 8 is fixed at the bottom end of the adjustment screw 7. The dial 11 is fixed on the bottom surface of the limit turning handle 8; the limit turning handle 8 has an "I" - shaped cylindrical structure. The top plate and the bottom plate of the limit turning handle 8 are symmetrically distributed up and down with respect to the limit piece 10. The top - surface diameter and the bottom - surface diameter of the limit turning handle 8 are both larger than the diameter of the installation port 9. The dial 11 has a "十" - shaped plate - like structure.

[0041] The spoiler is set to have an automatic sensing telescopic function. The height of the spoiler can be adjusted accordingly with the change of the train speed, and the maximum telescopic range can reach 50mm. When the train runs at a lower speed (below 250km / h) and the in-car noise caused by external air pressure or vibration is controlled within the industry standard limit, the spoiler remains closed, that is, the height is 0 mm; when the train speed exceeds 250km / h and the in-car noise exceeds the industry standard limit, the spoiler automatically rises to a certain height (30~50mm) to achieve the purpose of separating the larger vortex structure in the air flow, reducing the flow-induced vibration in this area, thereby reducing the in-car noise, and meeting the same set of spoilers to meet the use requirements of trains with different speeds such as EMUs, high-speed railways, and Fuxing trains; that is, trains with different speeds have different heights of spoilers because of different windward speeds; the height adjustment of the spoiler can be completed by adjusting the distance between the spoiler base plate 1 and the extension buckle plate 2. The specific operation is as follows: put both hands into the two installation grooves 3, and turn the paddle 11 to drive the corresponding limit handle 8 to rotate. The limit handle 8 drives the corresponding adjusting screw 7 to rotate synchronously. When the adjusting screw 7 rotates clockwise, it drives the corresponding silk sleeve 5 to rise along the perforation 4. At this time, the extended buckle plate 2 is supported upward by the silk sleeve 5, that is, the distance between the spoiler base plate 1 and the extended buckle plate 2 becomes larger, and the height of the spoiler becomes larger. The rubber connecting block 6 is fixed between the silk sleeve 5 and the extended buckle plate 2 to reduce the displacement conflict when the silk sleeve 5 is raised and lowered; after the adjusting screw 7 is rotated counterclockwise, the distance between the spoiler base plate 1 and the extended buckle plate 2 is reduced.

[0042] The spoiler structure is designed to be highly adjustable. By adjusting the vertical distance between the spoiler base and the extended gusset plate, it can adapt to the needs of trains of different speeds. This design allows the same set of spoilers to be applied to multiple types of trains such as EMUs, high-speed trains, and Fuxing trains, improving the versatility and flexibility of the product.

[0043] Rubber sealing pieces 13 are fixed at both ends of the bottom plate of the spoiler substrate 1, and the top of the rubber sealing piece 13 is fixed on the side wall of the extended buckle plate 2. After the rubber sealing piece 13 is installed at both ends of the spoiler substrate 1 and the extended buckle plate 2, the mounting groove 3 is covered, but the area between the two ends of the rubber sealing piece 13 is not fixed on the spoiler substrate 1 and the extended buckle plate 2, that is, the rubber sealing piece 13 not only meets the requirement of covering the mounting groove 3, but also meets the requirement of elastic deformation when the distance between the spoiler substrate 1 and the extended buckle plate 2 is adjusted, ensuring that the mounting groove 3 is always covered and reducing the wind flow into the mounting groove 3. When the distance between the spoiler substrate 1 and the mounting groove 3 needs to be adjusted, the rubber sealing piece 13 is stretched and the fingers are inserted into the mounting groove 3 for operation.

[0044] Embodiment 3: Refer to the attached Fig.11 and Fig.12As shown, on the basis of the second embodiment, in order to fill the missing grooves on both sides after the spoiler height is adjusted, windward filling structures are embedded on both sides of the extended gusset plate 2. When the distance between the extended gusset plate 2 and the spoiler base plate 1 is increased, the windward filling structure blocks the gap between the spoiler base plate 1 and the extended gusset plate 2, serving as a windward surface; the windward filling structure includes a side groove 16, a connecting plug plate 17, a connecting slot 18 and a rubber baffle 19. The side grooves 16 are provided with two, and the two side grooves 16 are respectively opened at the extension On the two parallel side plates of the extension plate 2, the height of the side groove 16 is less than the height of the extension plate 2, and two groups of connecting plug plates 17 are provided. The two groups of connecting plug plates 17 are respectively fixed on the top surface of the side groove 16 and the top surface of the bottom plate of the spoiler substrate 1, and the rubber baffle 19 is located between the top surface of the side groove 16 and the bottom plate of the spoiler substrate 1. The top surface of the rubber baffle 19 and the bottom surface of the rubber baffle 19 are both provided with connecting slots 18, and the two groups of connecting plug plates 17 are respectively extended into and fixed in the two connecting slots 18.

[0045] When the rubber baffle 19 is fixed between the spoiler substrate 1 and the extended gusset plate 2, and the distance between the extended gusset plate 2 and the spoiler substrate 1 is increased, the rubber baffle 19 is stretched and deformed, and the rubber baffle 19 is blocked in the side groove 16, so as to avoid the formation of a groove between the spoiler substrate 1 and the extended gusset plate 2. The rubber baffle 19 is made of hard rubber, which meets the deformation requirements and the requirements for windward impact resistance.

[0046] The windward filling structure embedded on both sides of the extended gusset effectively fills the gap between the spoiler base plate and the extended gusset, avoiding the gap caused by the spacing adjustment, thereby improving the stability and sealing of the structure. At the same time, the use of rubber baffles or hard metal plates further enhances the wind impact resistance and durability of the filling structure.

[0047] Embodiment 4: On the basis of embodiment 3, in order to enrich the windward filling structure, a hard metal plate of fixed size can be used to replace the rubber baffle 19, that is, after the spacing between the spoiler substrate 1 and the extended gusset plate 2 is adjusted, the hard metal plate of matching height is inserted into the notch on the windward surface of the spoiler substrate 1 and the extended gusset plate 2, and the hard metal plate is fixed in the notch by bonding or screwing, thereby avoiding the minimal impact caused by slight deformation of the filling structure at the notch of the spoiler substrate 1 and the extended gusset plate 2 caused by excessive wind force.

[0048] Embodiment 5: In order to fix the spoiler substrate 1 on the top of the train 20, both sides of the bottom plate of the spoiler substrate 1 are provided with embedded welding seams. When the spoiler substrate 1 is installed on the top of the train 20 by welding, the welding point between the spoiler substrate 1 and the train 20 is in the embedded welding seam; the embedded welding seam includes a reserved welding seam 14 and a second rubber sealing piece 15. The reserved welding seam 14 is opened on the bottom surface of the spoiler substrate 1, and the second rubber sealing piece 15 is fixed on the top surface of the reserved welding seam 14. The width of the second rubber sealing piece 15 is less than the depth of the reserved welding seam 14, and the rubber sealing piece 15 is The height of the second piece 15 is greater than the height of the reserved weld 14; that is, when the spoiler substrate 1 is fixed to the top of the train 20 by welding, after the bottom end of the second rubber sealing piece 15 is turned over, the bottom plate of the spoiler substrate 1 is welded to the top of the train 20, the welding node is in the reserved weld 14, the welding node protruding from the reserved weld 14 is polished, and then the second rubber sealing piece 15 is turned back to cover the welding node, which not only protects the welding node, but also avoids the wind interference effect affected by the uneven welding between the bottom end of the spoiler substrate 1 and the top surface of the train 20.

[0049] A reserved groove 12 is provided on the bottom surface of the mounting groove 3, and the reserved groove 12 is a "U"-shaped groove. A through hole is provided on the bottom surface of the reserved groove 12 for inserting bolts, that is, when the spoiler substrate 1 is fixed to the top of the train 20 without welding, the rod body of the screw-connected structure is passed through the through hole and then screwed to the top surface of the train 20, thereby fixing the spoiler substrate 1 to the top of the train 20.

[0050] Embodiment 6: Based on Embodiment 5, a method for using a novel high-speed train outer windshield structure is proposed, comprising the following steps:

[0051] Step 1: The spoiler is set to have an automatic sensing extension function. The height of the spoiler can be adjusted accordingly with the change of the train speed, and the maximum extension range can reach 50mm. When the train runs at a lower speed (below 250km / h) and the in-car noise caused by external air pressure or vibration is controlled within the industry standard limit, the spoiler remains closed, that is, the height is 0mm; when the train speed exceeds 250km / h and the in-car noise exceeds the industry standard limit, the spoiler automatically rises to a certain height (30~50mm) to achieve the purpose of separating the larger vortex structure in the air flow, reducing the flow-induced vibration in this area, thereby reducing the in-car noise, and meeting the same set of spoilers to meet the use requirements of trains with different speeds such as EMUs, high-speed railways, and Fuxing trains; that is, trains with different speeds have different windward speeds, so the height of the spoiler is also different; By adjusting the distance between the spoiler base plate 1 and the extended gusset plate 2, the height adjustment of the spoiler can be completed. The specific operation is as follows: put both hands into the two installation grooves 3, turn the paddle 11 to drive the corresponding limit rotating handle 8 to rotate, and the limit rotating handle 8 drives the corresponding adjusting screw 7 to rotate synchronously. When the adjusting screw 7 rotates clockwise, it drives the corresponding wire sleeve 5 to rise along the perforation 4. At this time, the extended gusset plate 2 is supported upward by the wire sleeve 5, that is, the distance between the spoiler base plate 1 and the extended gusset plate 2 becomes larger, and the height of the spoiler becomes larger. The rubber connecting block 6 is fixed between the wire sleeve 5 and the extended gusset plate 2 to reduce the displacement conflict when the wire sleeve 5 is raised and lowered; after the adjusting screw 7 is turned counterclockwise, the distance between the spoiler base plate 1 and the extended gusset plate 2 is reduced;

[0052] Step 2: Rubber sealing pieces 13 are fixed at both ends of the bottom plate of the spoiler substrate 1, and the top of the rubber sealing piece 13 is fixed on the side wall of the extended gusset plate 2. After the rubber sealing piece 13 is installed at both ends of the spoiler substrate 1 and the extended gusset plate 2, the mounting groove 3 is covered, but the area between the two ends of the rubber sealing piece 13 is not fixed on the spoiler substrate 1 and the extended gusset plate 2, that is, the rubber sealing piece 13 not only meets the requirements of covering the mounting groove 3, but also meets the requirements of elastic deformation when the spacing between the spoiler substrate 1 and the extended gusset plate 2 is adjusted, so as to ensure that the mounting groove 3 is always covered and reduce the wind flow into the mounting groove 3. When the spacing between the spoiler substrate 1 and the mounting groove 3 needs to be adjusted, the rubber sealing piece 13 is stretched and the fingers are inserted into the mounting groove 3 for operation;

[0053] Step three: After the rubber baffle 19 is fixed between the spoiler substrate 1 and the extended gusset plate 2, and the distance between the extended gusset plate 2 and the spoiler substrate 1 is increased, the rubber baffle 19 is stretched and deformed, and the rubber baffle 19 is blocked in the side groove 16, so as to avoid the formation of a groove between the spoiler substrate 1 and the extended gusset plate 2. The rubber baffle 19 is made of hard rubber, which meets the deformation requirements and the requirements for windward impact resistance.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
