Description

Technical Field

[0001] This application relates to the technical field of maglev trains, and particularly relates to a capsule device and a maglev train. Background Art

[0002] Currently, external windshields are generally installed between adjacent carriages of rail vehicles. The external windshields usually include a metal frame and a capsule. The capsule is assembled on the metal frame by means of a metal strip and fasteners, which plays roles such as reducing the noise inside the vehicle, slowing down the air resistance when the vehicle is running at high speed, and improving the aerodynamic performance of the vehicle.

[0003] For example, the end capsules (windshields) of high-speed multiple units are mainly connected and fixed through frames, pressing plates and bolts. Sheaths need to be provided at the capsule eyeholes, resulting in a complex installation structure. Moreover, when passing through curves, when pulling forces are generated between the capsules, it is easy to cause shear tearing at the openings. At the same time, the end capsules are located at the arc parts, and the installation structure is made according to the shape, which is an arc surface structure. It is inconvenient for workers to operate during assembly, the eyeholes are not easy to be centered, and the support plate cannot be compacted with the arc surface frame.

[0004] Since the installation method of the end capsules of high-speed multiple units easily leads to a low service life of the capsules, inconvenient maintenance, and affects the functions of noise reduction, resistance reduction, flow guiding and buffering during the use of the capsules, while maglev trains have high requirements for the service life, maintenance convenience, flow guiding, resistance reduction and buffering functions of the capsules. Therefore, the existing end capsule structures of high-speed multiple units are not applicable to maglev trains.

[0034] The capsule device provided in the embodiment of the present application is used to be installed on the suspension frame of a maglev train. The suspension frame of a maglev train is a key subsystem for carrying the maglev train, and the suspension frame affects the suspension stability, comfort and safety of the train.

[0035] The suspension frame realizes the suspension and guidance of the train through the magnetic field interaction between the electromagnet and the track. In the design of the maglev train, the structure and materials of the suspension frame have an important impact on the performance of the train. The capsule device provided in the embodiment of the present application is installed at the outer end of the suspension frame of the maglev train, and as the diversion capsule at the outer end of the suspension frame, it mainly plays roles such as noise reduction, resistance reduction, diversion, and buffering.

[0036] The capsule device provided in the embodiment of the present application includes a capsule body 10 and a mounting assembly 20.

[0037] The capsule body 10 is a continuous closed-loop structure. The capsule body 10 includes an annular outer wall 11 and an annular inner wall 12 provided inside the annular outer wall 11. The annular outer wall 11 is provided with a first mounting structure 111, and the annular inner wall 12 is provided with a second mounting structure 121.

[0038] The mounting assembly 20 includes a mounting base 21, a first pressing plate 22, and a second pressing plate 23. The mounting base 21 is provided with an outer frame 211 and a boss 212. The first pressing plate 22 is connected to the mounting base 21, so that the first pressing plate 22 and the outer frame 211 form a first mounting groove 24 for mounting the first mounting structure 111. The second pressing plate 23 is connected to the mounting base 21, so that the second pressing plate 23 and the boss 212 form a second mounting groove 25 for mounting the second mounting structure 121.

[0039] That is to say, the first mounting groove 24 formed by the first pressing plate 22 and the outer frame 211 is connected in cooperation with the first mounting structure 111, so that the annular outer wall 11 of the capsule body 10 is mounted on the mounting assembly 20. The second mounting groove 25 formed by the second pressing plate 23 and the boss 212 is connected in cooperation with the second mounting structure 121, so that the annular inner wall 12 of the capsule body 10 is mounted on the mounting assembly 20. In this way, the capsule body 10 can be mounted on the mounting assembly 20.

[0040] With such a setting, the installation of the capsule body 10 in the capsule device provided in the embodiment of the present application is designed as a mounting groove fixing structure without screw fixation. Compared with the mounting structure of the traditional EMU end capsule with openings and exposed screw pressing plates, the capsule body 10 of the capsule device provided in the embodiment of the present application does not need to be provided with connection holes, avoiding the situation that the service life is affected by shear and compression at the capsule opening and the exposed screws, improving the service life and maintenance convenience of the capsule body 10, and ensuring the functions of diversion, resistance reduction, and buffering of the capsule body 10. Thus, the capsule device provided in the embodiment of the present application can be applied to maglev trains, solving the technical problem that the existing end capsule structure of high-speed EMUs cannot be applied to maglev trains.

[0041] In some embodiments, both the first mounting groove 24 and the second mounting groove 25 are C-shaped grooves.

[0042] In this embodiment, the first mounting structure 111 includes two first card slots 1111, which are respectively arranged on two side walls of the annular outer wall 11 along the first direction. Both the first pressing plate 22 and the outer frame 211 include first clamping protrusions 221. The first clamping protrusions 221 are in clamping fit with the corresponding first card slots 1111, so that the annular outer wall 11 is fixed to the first mounting groove 24.

[0043] It should be noted that the above-mentioned first direction is the horizontal direction as shown in Figure 4 the figure.

[0044] In this way, the first pressing plate 22 and the outer frame 211 form a C-shaped groove in a horizontal posture. The first clamping protrusions 221 on the first pressing plate 22 and the first clamping protrusions 221 of the outer frame 211 are used as the two ends of the C-shaped groove, and are respectively used for clamping and fitting with the two first card slots 1111, so that the annular outer wall 11 of the capsule body 10 is installed on the mounting assembly 20.

[0045] During installation, first insert the first card slot 1111 on the right side of the annular outer wall 11 of the capsule body 10 into the first clamping protrusion 221 of the outer frame 211. Then, install the first pressing plate 22 and insert the first clamping protrusion 221 on the first pressing plate 22 into the first card slot 1111 on the left side of the annular outer wall 11.

[0046] In some embodiments, the second mounting structure 121 includes two second card slots 1211, which are respectively arranged on two side walls of the annular inner wall 12 along the second direction. The second pressing plate 23 includes a second clamping protrusion 231, and the second clamping protrusion 231 faces the boss 212. The second clamping protrusion 231 and the boss 212 are respectively in clamping fit with the two second card slots 1211, so that the annular inner wall 12 is fixed to the second mounting groove 25.

[0047] It should be noted that the above-mentioned second direction is the vertical direction as shown in Figure 4 the figure.

[0048] In this way, the second pressing plate 23 and the boss 212 on the mounting base 21 form a C-shaped groove in a vertical posture. The second clamping protrusion 231 on the second pressing plate 23 and the boss 212 on the mounting base 21 are used as the two ends of the C-shaped groove, and are respectively used for clamping and fitting with the two second card slots 1211, so that the annular inner wall 12 of the capsule body 10 is installed on the mounting assembly 20.

[0049] During installation, first insert the second card slot 1211 on the lower side of the annular inner wall 12 of the capsule body 10 into the boss 212 on the mounting base 21. Then, install the second pressing plate 23 and insert the second clamping protrusion 231 on the second pressing plate 23 into the second card slot 1211 on the upper side of the annular inner wall 12.

[0050] It can be seen that the installation of the entire capsule body 10 is carried out in the order from outside to inside. When installing the annular outer wall 11 of the capsule body 10, first, the first card slot 1111 on the right side of the annular outer wall 11 of the capsule body 10 is snapped into the first card projection 221 of the outer frame 211. Then, the first pressing plate 22 is installed, and the first card projection 221 on the first pressing plate 22 is snapped into the first card slot 1111 on the left side of the annular outer wall 11. After the installation of the annular outer wall 11 of the capsule body 10 is completed, the installation of the annular inner wall 12 of the capsule body 10 is carried out. Specifically, first, the second card slot 1211 on the lower side of the annular inner wall 12 of the capsule body 10 is snapped into the boss 212 on the mounting seat 21. Then, the second pressing plate 23 is installed, and the second card projection 231 on the second pressing plate 23 is snapped into the second card slot 1211 on the upper side of the annular inner wall 12.

[0051] In some embodiments, the second pressing plate 23 further includes a bent plate body 232, and the second card projection 231 is provided at the end of the bent plate body 232, such that the second card projection 231 faces the boss 212.

[0052] Specifically, the bent plate body 232 is of an L-shaped structure, and the second card projection 231 is provided on the short side of the bent plate body 232 and is perpendicular to the short side.

[0053] In addition, the second pressing plate 23 further includes a connecting plate body 233. The connecting plate body 233 is of a flat plate structure. The connecting plate body 233 is provided at one end of the bent plate body 232 away from the second card projection 231. That is to say, the connecting plate body 233 is provided at the long side end of the L-shaped bent plate body 232. The connecting plate body 233 is detachably connected to the mounting seat 21 through a second fastener 27.

[0054] Certainly, the second fastener 27 can be a fastening screw. The fastening screw passes through the connecting plate body 233 and is threadedly connected to the mounting seat 21 to lock the second pressing plate 23 to the mounting seat 21.

[0055] In some embodiments, the first pressing plate 22 includes a plurality of pressing plate bodies 222. Each pressing plate body 222 forms the first pressing plate 22 through continuous splicing, and the second pressing plate 23 is of an integral structure.

[0056] Among them, each pressing plate body 222 is detachably connected to the mounting seat 21 through a first fastener 26.

[0057] It should be noted that the above-mentioned second pressing plate 23 is a continuous integral structure. After the second clamping groove 1211 on the lower side of the annular inner wall 12 of the capsule body 10 is snapped into the boss 212 on the mounting seat 21, the second pressing plate 23 is integrally mounted on the mounting seat 21, and the second clamping protrusion 231 on the second pressing plate 23 is snapped into the second clamping groove 1211 on the upper side of the annular inner wall 12. Finally, the second fastener 27 is used for fixed connection. Different from the second pressing plate 23, the first pressing plate 22 is composed of discontinuous (independent) pressing plate bodies 222. The pressing plate bodies 222 are sequentially spliced to form the structure of the first pressing plate 22, and each pressing plate body 222 is fixedly connected to the mounting seat 21 through the first fastener 26.

[0058] Certainly, the first fastener 26 can also be a fastening screw. The fastening screw passes through the corresponding pressing plate body 222 and is threadedly connected to the mounting seat 21 so that the corresponding first pressing plate 22 is locked to the mounting seat 21.

[0059] In some embodiments, each first fastener 26 is accommodated in the inner cavity of the capsule body 10.

[0060] That is to say, each first fastener 26 is located between the annular outer wall 11 and the annular inner wall 12 of the capsule body 10. In this way, the inner cavity of the capsule body 10 is designed to accommodate all the first fasteners 26, realizing a compact assembly or design. At the same time, this hidden design places the first fastener 26 inside the capsule body 10, which helps to protect the first fastener 26 from damage or corrosion and improve its service life. In addition, this hidden design is also used for aesthetics or hiding the first fastener 26 to keep the neat appearance of the capsule device.

[0061] In some embodiments, the capsule body 10 is an integrally formed closed-loop structure.

[0062] By setting the capsule body 10, it can effectively play a protective role. For example, the capsule body 10 is made of ethylene propylene diene monomer (EPDM). EPDM has excellent anti-aging properties such as ozone resistance, heat resistance, and weather resistance, can fully adapt to various environments and high and low temperature environments, and has a certain stretching ability, which can effectively cope with the movement changes of the suspension frame of the maglev train and play roles such as noise reduction, drag reduction, flow guiding, and buffering.

[0063] In summary, in the present application, the outer continuous outer frame 211 and the first pressing plate 22 with a segmented middle part are combined to form a C-shaped groove to fix the annular outer wall 11 of the peripherally continuous annular capsule body 10, and the inner continuous boss 212 and the second pressing plate 23 are combined to form a C-shaped groove to fix the annular inner wall 12 of the peripherally continuous annular capsule body 10, solving the problems such as the influence of shear and compression on the service life at the capsule opening and the exposed screws on the outside in rail transit products. In addition, it can also improve the maintenance efficiency, etc.
