Description

Technical Field

[0001] The present invention relates to the technical field of rail transit vehicles, and particularly relates to an external windshield system and a multiple unit train. Background Art

[0002] As an important part of modern railway transportation, high-speed multiple unit trains have the advantages of high speed, large transportation capacity, high comfort, etc., and play an important role in promoting economic and social development and improving people's living standards. The external windshield of a high-speed multiple unit train is an important part of the high-speed multiple unit train. Its main function is to reduce wind resistance and turbulence, provide a good streamline for the high-speed operation of the vehicle, meet the requirements of aerodynamics, and reduce energy consumption. Therefore, optimizing the design of the external windshield of a high-speed multiple unit train is of great significance for improving the operation efficiency and reducing energy consumption of the high-speed multiple unit train.

[0003] The external windshield of a traditional high-speed multiple unit train generally includes an external windshield main body and a rubber capsule. In order to install the rubber capsule on the external windshield main body, installation holes need to be opened on the rubber capsule, and then bolts are passed through the installation holes on the side wall of the external windshield main body and the installation holes on the rubber capsule and tightened with nuts to install the external windshield main body and the rubber capsule together. In order to facilitate the installation of bolts and nuts, a plurality of process holes need to be opened on the rubber capsule, and installers need to put their hands into the process holes to place and fix the bolts. Opening installation holes and process holes on the rubber capsule is prone to stress concentration at the holes, making the relative positions of the holes fragile. During long-term operation, the rubber at the holes is prone to wear and aging, resulting in a decrease in the service life of the rubber capsule, and seriously affecting the overall performance of the external windshield in severe cases.

[0004] Through retrieval, it is found that there are patents related to the present invention to a certain extent. For example, the Chinese utility model patent with the authorization announcement number CN209683692U, the authorization announcement date of November 26, 2019, and the name of "An External Windshield of a High-Speed Multiple Unit Train" discloses an external windshield of a high-speed multiple unit train. This patent also needs to open installation holes on the rubber capsule and install the rubber capsule on the external windshield main body through bolts, which will also cause problems such as wear and aging of the rubber capsule affecting its service life, and seriously affecting the overall performance of the external windshield in severe cases.

[0005] In summary, how to design an external windshield system and a multiple unit train to avoid opening installation holes and process holes on the rubber capsule, improve the service life of the rubber capsule, and improve the overall performance of the external windshield is an urgent technical problem to be solved.

[0022] In order to make the objectives, technical solutions and advantages of the embodiments of the invention clearer, the following will combine the appended Figures 1 - 9, the technical solutions of the invention embodiments are described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0023] It should be noted that all directional indications (such as up, down, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship of components in a certain specific posture (as shown in the attached drawings). If this specific posture changes, the directional indications will change accordingly. Embodiment

[0024] As Figure 1 shown, the outer windshield system 3 is connected between the vehicle body one 1 and the vehicle body two 2 to reduce wind resistance and turbulence, provide a good streamline for the high-speed operation of the vehicle, meet the requirements of aerodynamics, and reduce energy consumption. As Figure 2 shown, the outer windshield system 3 of this embodiment includes an outer windshield main body 31, a rubber capsule 32, and a locking device 4. The locking device 4 mounts the rubber capsule 32 on the outer windshield main body 31. The locking device 4 includes two fasteners 41 and a pressing plate 42 that can cooperate with the fasteners 41 for locking. Inner bead one 322 and inner bead two 323 are provided at the ends of the rubber capsule 32. One fastener 41 passes through the mounting base one 3112 of the outer windshield main body 31 and the pressing plate one 421 and cooperates with the pressing plate one 421 to lock the inner bead one 322 between the mounting base one and the pressing plate one 421. The other fastener 41 passes through the mounting base two 3122 of the outer windshield main body 31 and the pressing plate two 422 and cooperates with the pressing plate two 422 to lock the inner bead two 323 between the mounting base two 3122 and the pressing plate two 422, thereby mounting the rubber capsule 32 onto the outer windshield main body 31.

[0025] By setting the locking device 4, it is possible to mount the rubber capsule 32 onto the outer windshield main body 31 without having to open multiple mounting holes and process holes on the rubber capsule 32, effectively avoiding the problems in the background technology where multiple mounting holes and process holes need to be opened on the rubber capsule, stress concentration is likely to occur at the holes, making the relative positions of the holes vulnerable, the rubber at the hole positions is prone to wear and aging during long-term operation, resulting in a decrease in the service life of the rubber capsule, and in severe cases, it will also affect the overall performance of the outer windshield.

[0026] As Figure 3As shown, the outer windshield main body 31 is of a split design, which includes an inner frame body 311 and an outer frame body 312. The inner frame body 311 and the outer frame body 312 are connected together by a connecting member; an outer bead one 3111 is provided on the outer side of the inner frame body 311, and an outer bead two 3121 is provided on the outer side of the outer frame body 312. The outer bead one 3111 is fixedly connected to the mounting base one 3112 of the inner frame body, and the outer bead two 3121 is fixedly connected to the mounting base two 3122 of the outer frame body. As Figure 4 shown, the cross-section of the rubber capsule 32 is a U-shaped rubber surface 321, and the upper ends of the inner bead one 322 and the inner bead two 323 are vulcanized on the inner walls of the two ends of the rubber capsule 32 respectively. As Figure 5 shown, the outer bead one 3111 and the inner bead one 322 press one end of the rubber capsule 32 between the outer bead one 3111 and the inner bead one 322, and the outer bead two 3121 and the inner bead two 323 press one end of the rubber capsule 32 between the outer bead two 3121 and the inner bead two 323. By setting the inner bead one 322 and the outer bead one 3111 to cooperate to press one side of the rubber capsule 32 on the inner frame body 311, and the inner bead two 323 and the outer bead two 3121 to press the other side of the rubber capsule 32 on the outer frame body 312, it is beneficial to the sealing performance of the outer windshield system and ensures the operation efficiency of the EMU.

[0027] As Figure 3 shown, a mounting groove one 3113 is formed on the mounting base one 3112, and a mounting groove two 3123 is formed on the mounting base two 3122. A step one 4211 and a step two 4221 are respectively provided at the lower ends of the pressing plate one 421 and the pressing plate two 422. The lower end of the inner bead one 322 is arranged in the limiting space one 5 formed by the mounting groove one 3113 and the step one 4211, and the lower end of the inner bead two 323 is arranged in the limiting space two 6 formed by the mounting groove two 3123 and the step two 4221. By setting the mounting groove one 3113, the mounting groove two 3123, the step one 4211 and the step two 4221, the mounting groove one 3113 and the step one 4211 form a limiting space 5 that can limit the lower end of the inner bead one 322, and the mounting groove two 3123 and the step two 4221 form a limiting space 6 that can limit the lower end of the inner bead two 323, so as to fix the lower ends of the inner bead one 322 and the inner bead two 323 on the outer windshield main body. The reliability of the connection between the inner bead one 322 and the mounting base one 3112 and the connection between the inner bead two 323 and the mounting base two 3122 is increased.

[0028] In this embodiment, as Figure 5 and Figure 7As shown in the figure, the connecting member that connects the inner frame body 311 and the outer frame body 312 includes two parts: a locking tongue 3114 and a frame connecting block 313 that cooperates with the locking tongue 3114. The locking tongue 3114 is provided on the inner side of the inner frame body 311 and protrudes towards the outer frame body. One end of the frame connecting block 313 is fitted together with the locking tongue 3114. The other end of the frame connecting block 313 is provided with a through hole for a small threaded hole, and a corresponding small threaded hole is also provided on the outer frame body. The other end of the frame connecting block 313 is connected to the outer frame body 312 by tightening it with a small bolt, thereby connecting the inner frame body 311 and the outer frame body 312 together. The locking tongue and the frame connecting block are used to cleverly connect the inner frame body and the outer frame body together. Only one side needs to be tightened, which saves installation time and improves the installation work efficiency.

[0029] As Figure 5 shown in the figure, both the first pressing plate 421 and the second pressing plate are provided with the first threaded through holes 3115. Threaded through holes 4212 are provided in the first mounting base 3112 and the second mounting base 3122. The fastener 41 sequentially passes through the first threaded through holes 3115 and the threaded through holes 4212 to press the first inner pressing plate 421 and the second inner pressing plate 422 against the first inner pressing strip 322 and the second inner pressing strip 323 respectively. Through the above settings, it is possible to install the rubber capsule on the outer windshield main body without opening an installation hole in the rubber capsule.

[0030] It should be noted that in this embodiment, the fastener is a bolt, and it can also be any other fastening component.

[0031] As Figure 4 shown in the figure, a layer of damping pad 324 is provided at the lower ends of the first inner pressing strip 322 and the second inner pressing strip 323. The damping pad 324 is vulcanized at the lower ends of the first inner pressing strip 322 and the second inner pressing strip 323. The damping pad 324 is in contact with the first limiting space 5 and the second limiting space 6. The purpose of doing this is to make the connection a flexible connection, which can absorb and buffer the vibration energy at the connection position and also improve the overall service life.

[0032] As Figure 5 shown in the figure, the first threaded through hole 3115 is a through hole in the shape of a bolt. After the bolt is installed, the bolt head 411 is flush with the lower end surfaces of the first mounting base 3112 and the second mounting base 3122. The purpose of doing this is to prevent the bolt head 411 from interfering with the first vehicle body 1 and the second vehicle body 2.

[0033] The present invention also discloses an assembly method for an outer windshield system. As Figures 2 to 7As shown in the figure, one side of the lower end of the inner pressure strip 1-322 has a bump 1-3222 that matches the first installation groove 3-3113, and the other side has a limit block 1-3221 that matches the step 1-4211 of the first pressing plate 4-421; one side of the lower end of the inner pressure strip 2-323 has a bump 2-3232 that matches the second installation groove 3-3123, and the other side has a limit block 2-3231 that matches the step 2-4221 of the second pressing plate 4-422; The method for assembling the outer windshield system is as follows: First, place the rubber capsule flat on the workbench with the opening facing upward, and then place the bump 1-3222 and the bump 2-3232 respectively in the first installation groove 3-3113 and the second installation groove 3-3123. Then, press the first pressing plate 4-421 and the second pressing plate 4-422 on the limit block 1-3221 and the limit block 2-3231, so that the step 1-4211 and the step 2-4221 are respectively in contact with the limit block 1-3221 and the limit block 2-3231. Then, pass the bolts through the first threaded through-hole 3-3115 and the second threaded through-hole 4-4212 in sequence to press the first inner pressing plate 4-421 and the second inner pressing plate 4-422 on the limit block 1-3221 and the limit block 2-3231 respectively, thereby connecting the rubber capsule 32 to the inner frame body 3-311 and the outer frame body 3-312.

[0034] Then, fix the four corners of the rubber capsule 32 on the inner frame body 3-311 and the outer frame body 3-312, and then place the rubber capsule 32, the inner frame body 3-311 and the outer frame body 3-312 as a whole on the workbench for fixing other parts; Finally, connect one end of the frame connection block 3-313 to the locking tongue 3-3114, place the other end of the frame connection block 3-313 on the outer frame body 3-312, and fix it on the outer frame body 3-312 with bolts, so that the inner frame body 3-311 and the outer frame body 3-312 can be connected into a whole.

[0035] It should be noted that after installation, the frame connection block 3-313 needs to be in the same plane as the inner plane of the outer windshield main body 3-31. To avoid interference between the outer windshield system and the vehicle body 1 and the vehicle body 2 during installation.

[0036] Through the above assembly method, there is no need to reach into the inside of the rubber capsule through the side process hole of the rubber capsule by hand for installation and tightening operations. Only need to place the rubber capsule horizontally on the workbench with the opening facing upward first, and then connect the outer windshield main body and the rubber capsule. The operation is simple and the assembly efficiency is improved.

[0037] The present invention also provides a multiple unit train, such as Figure 1 、 Figure 8 and Figure 9As shown in the figure, connecting arms I 7 are provided on both the first mounting base 3112 and the second mounting base 3122 of the external windshield system 3. Connecting arms II 8 that match the connecting arms I 7 are provided on both the first vehicle body 1 and the second vehicle body 2. The connecting arms I 7 and the connecting arms II 8 can be interlocked or disassembled, so as to connect the external windshield system 3 between the first vehicle body 1 and the second vehicle body 2 or quickly disassemble it from between the first vehicle body 1 and the second vehicle body 2. The above-provided connecting arms I 7 and connecting arms II 8 can achieve the functions of quick installation and then disassembly.

[0038] The above embodiments are only for illustrating the present invention, rather than limiting the present invention. Those skilled in the relevant technical fields can also make various changes or transformations without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the protection scope of the present invention, and the protection scope of the present invention should be defined by each claim.
