Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] The core of this invention is to provide a wind source device for a maglev vehicle, which is easy to install. Another core aspect of this invention is to provide a maglev vehicle including the aforementioned wind source device, which facilitates the installation of the wind source device.

[0038] Please refer to Figure 1 and Figure 2 This invention provides a maglev vehicle air supply device for installation in an equipment mounting box 1. The equipment mounting box 1 is used for installation in a maglev vehicle. The maglev vehicle air supply device includes an air supply device 2 and at least two air cylinder modules. The air supply device 2 and the air cylinder modules are both located inside the equipment mounting box 1. Each air cylinder module includes at least one air cylinder. The air cylinder modules are arranged in layers along the vertical direction, and each layer includes at least one air cylinder module.

[0039] In other words, this embodiment of the invention adopts a modular design for the air supply device of the maglev vehicle, dividing it into multiple different modules, namely the air supply device 2 and various air cylinder modules. This facilitates installation and allows for full utilization of the internal space of the equipment mounting box 1 through a reasonable layout of the modules. The air cylinder modules are arranged in a layered manner, which helps meet installation space requirements and facilitates pipeline connections. Furthermore, the air cylinders are divided into different air cylinder modules, each including at least one air cylinder. This adopts the approach of designing small-capacity air cylinders, reducing their volume while increasing their number, thus meeting the vehicle's air supply needs while making reasonable and effective use of the installation space. Therefore, this maglev vehicle air supply device can be installed even in confined installation spaces, has a compact structure, and is easy to install.

[0040] It should be noted that the present invention does not limit the relative positional relationship between the air supply device 2 and the air cylinder module. For example, the air supply device 2 can be arranged in one of the following three ways: the air supply device 2 is located on top of the topmost air cylinder module; the air supply device 2 is located between any two layers of air cylinder modules; the air supply device 2 is located on the same layer as any layer of air cylinder module. The key is to ensure that the air supply device 2 is located outside the air cylinder module to facilitate heat dissipation.

[0041] Furthermore, this embodiment does not limit the specific number of air cylinder modules or the number of air cylinders contained in each air cylinder module. The number of air cylinders contained in each air cylinder module can be the same or different. For example, Figure 1As shown, in some embodiments, there are two air cylinder modules, namely a dual air cylinder module 3 and a five air cylinder module 4. The dual air cylinder module 3 includes two air cylinders (such as...). Figure 4 As shown), the five-cylinder module 4 includes five cylinders (such as...). Figure 5 (As shown). In this case, the air supply device 2 and the dual-cylinder module 3 are located on the same floor, on the upper floor, while the five-cylinder module 4 is located on the lower floor, as shown. Figure 1 and 2 As shown.

[0042] In addition, in order to facilitate the installation of the air supply device 2 and each air cylinder module in the equipment mounting box 1, in some embodiments, the equipment mounting box 1 is provided with at least one equipment mounting beam, and the air supply device 2 and the air cylinder module can be pushed and pulled relative to the corresponding equipment mounting beam and are respectively fixed to the corresponding equipment mounting beam.

[0043] In other words, during installation, the air supply device 2 and the air cylinder module are installed onto the corresponding equipment mounting beams by pushing and pulling, and after being pushed and pulled into place, the air supply device 2 and the air cylinder module are fixed to the corresponding equipment mounting beams.

[0044] Considering the method of fixing the air supply device 2 and the air cylinder module to the corresponding equipment mounting beam, in some embodiments, the equipment mounting beam is provided with mounting holes, and the air supply device 2 and each air cylinder module are provided with welding nuts. After the air supply device 2 and the air cylinder module are installed in place, they are fixed to the corresponding equipment mounting beam by bolts passing through the corresponding mounting holes and welding nuts. This connection method is simple and convenient to operate. In some embodiments, the air supply device 2 is provided with a first support frame 7 (e.g., Figure 6 As shown), there are two air cylinder modules: a double air cylinder module 3 and a five air cylinder module 4. The double air cylinder module 3 is equipped with a second support frame 8 (as shown). Figure 7 As shown), the five-cylinder module 4 is equipped with a third support frame 9 (as shown). Figure 8 As shown), the first support frame 7, the second support frame 8, and the third support frame 9 are respectively provided with the aforementioned welded nuts.

[0045] It should be noted that this embodiment does not limit the specific number of equipment mounting beams, as long as the number of equipment mounting beams can meet the installation requirements of the air supply device 2 and each air cylinder module. For example... Figure 2As shown, in some embodiments, when there are two air cylinder modules, namely a double air cylinder module 3 and a five air cylinder module 4, there are two equipment mounting beams, namely an upper equipment mounting beam 5 and a lower equipment mounting beam 6. The upper equipment mounting beam 5 and the lower equipment mounting beam 6 are arranged in pairs, that is, the two upper equipment mounting beams 5 are respectively located on the left and right sides of the equipment mounting box 1, and the two lower equipment mounting beams 6 are respectively located on the left and right sides of the equipment mounting box 1, so as to improve the stability and reliability of the air supply device 2, the double air cylinder module 3 and the five air cylinder module 4 during installation.

[0046] During installation, push and pull the double air cylinder module 3 along the upper equipment mounting beam 5 into place, and fix the double air cylinder module 3 from the space below it; then, push and pull the air supply device 2 along the upper equipment mounting beam 5 into place, and fix the air supply device 2 from the space below it; finally, install the five air cylinder module 4, and push and pull the five air cylinder module 4 along the lower equipment mounting beam 6 into place and fix it.

[0047] In addition, such as Figure 3 As shown, in order to facilitate the pipe connection between the air supply device 2 and the air cylinder module, as well as between each air cylinder module, in some embodiments, an operation window 10 is provided on the side of the equipment installation box 1. The operation window 10 is used to realize the pipe connection between the air supply device 2 and the air cylinder module, as well as between each air cylinder module.

[0048] In other words, this embodiment provides a side operating space for the pipe connection between the air supply device 2 and the air cylinder module, as well as between each air cylinder module, by opening an operating window 10 on the side of the equipment installation box 1, so that the pipe connection between the air supply device 2 and the air cylinder module, as well as between each air cylinder module, can be realized from the side operating space.

[0049] It should be noted that this embodiment does not limit the specific size of the operation window 10, as long as it can meet the operation space requirements.

[0050] Furthermore, in some embodiments, the air supply device 2 is connected to the air cylinder module and to each air cylinder module via flexible hoses, and the hose connections are made via quick-connect couplings. This method is convenient to operate and can effectively utilize the side operating space.

[0051] The following section uses two air cylinder modules, namely double air cylinder module 3 and five air cylinder module 4, as examples to introduce the pipeline connection between air supply device 2 and double air cylinder module 3, as well as between double air cylinder module 3 and five air cylinder module 4.

[0052] For example, such as Figure 6 and Figure 7As shown, the first air hose 11, used to connect the air supply device 2 and the dual air cylinder module 3, is pre-installed on the dual air cylinder module 3. One of the air supply device 2 and the first air hose 11 is provided with a first quick-connect male terminal, and the other is provided with a first quick-connect female terminal 12. After the air supply device 2 and the dual air cylinder module 3 are installed in place, the first quick-connect male terminal and the first quick-connect female terminal 12 are plugged in from the operating space on the side of the equipment mounting box 1 to connect the first air hose 11 to the air supply device 2.

[0053] Furthermore, such as Figure 1 As shown, the bracket of the air supply device 2 and / or the dual air cylinder module 3 is provided with a first fixing hole 13 for threading a cable tie. After the first air hose 11 is connected to the air supply device 2, the first air hose 11 is fixed with a cable tie.

[0054] in addition, Figure 2 and Figure 3 As shown, in some embodiments, a second air hose 14 for connecting the dual-cylinder module 3 and the five-cylinder module 4 is pre-assembled on the five-cylinder module 4. One of the dual-cylinder module 3 and the five-cylinder module 4 is provided with a second quick-connect male terminal 16, and the other is provided with a second quick-connect female terminal 15. After the dual-cylinder module 3 and the five-cylinder module 4 are installed in place, the second quick-connect male terminal 16 and the second quick-connect female terminal 15 are plugged in from the operating space on the side of the equipment mounting box 1 to connect the second air hose 14 to the dual-cylinder module 3.

[0055] Additionally, to facilitate the arrangement of the upper air cylinder module's drain hose 17 (such as... Figure 7 As shown), in some embodiments, the cylinder module located below any one of the cylinder modules is provided with a support frame, and the drain hose 17 of the cylinder module located above the bottommost cylinder module is arranged along the support frame of the cylinder module below it. For example, in some embodiments, there are two cylinder modules, namely a double cylinder module 3 and a five-cylinder module 4. The double cylinder module 3 is located above the five-cylinder module 4. In this case, the five-cylinder module 4 is provided with a third support frame 9, and the drain hose 17 of the double cylinder module 3 is arranged along the third support frame 9.

[0056] In other words, in this embodiment, the drainage hose 17 of the upper-level air cylinder module is arranged on the support frame of the lower-level air cylinder module, so that the drainage hose 17 extends and is arranged along the direction guided by the support frame. This facilitates the drainage hose 17 to be led to the drainage module, which is beneficial for the drainage of the upper-level air cylinder module. The drainage module of the lowest-level air cylinder module can have a separate space opened on the bottom plate of the equipment mounting box 1 to meet the drainage space requirements of each air cylinder module.

[0057] Furthermore, such as Figure 8As shown, in some embodiments, the support frame has a through hole for the drainage hose 17 to pass through, and a flexible bushing 18 is provided at the through hole. That is, in this embodiment, by providing a through hole in the support frame, the drainage hose 17 passes through the through hole, which facilitates the drainage hose 17's path toward its corresponding drainage module, reducing the path length of the drainage hose 17. At the same time, the through hole can also be used to circumferentially limit the drainage hose 17. In addition, the flexible bushing 18 at the through hole protects the drainage hose 17 and prevents wear.

[0058] It should be noted that this embodiment does not limit the specific material of the flexible bushing 18, as long as the flexible bushing 18 has a certain degree of flexibility and can protect the drain hose 17. For example, the flexible bushing 18 can be a rubber bushing.

[0059] In addition, in some embodiments, the support frame is provided with a fixing structure for fixing the drain hose 17.

[0060] For example, the support frame has fixing holes. By using a binding strap to pass through the fixing holes, the drain hose 17 can be fixed, which helps to ensure that the drain hose 17 remains in a fixed position and prevents the drain hose 17 from shaking randomly.

[0061] The following section uses two air cylinder modules, namely the double air cylinder module 3 and the five air cylinder module 4, as examples to introduce the routing and fixing of the drain hose 17.

[0062] like Figure 7 and Figure 8 As shown, the drain hose 17 of the dual-cylinder module 3 is pre-connected to the connector at the bottom of the dual-cylinder module 3. The five-cylinder module 4 is provided with a third support frame 9. The third support frame 9 has a through hole for the drain hose 17 of the dual-cylinder module 3 to pass through. A rubber bushing is pre-installed at the through hole. The third support frame 9 also has a second fixing hole 19 and a third fixing hole 20 for fixing the drain hose 17 of the dual-cylinder module 3.

[0063] After the air supply device 2, the dual-cylinder module 3, and the five-cylinder module 4 are all installed, operate from the side operating space of the equipment installation box 1. Arrange the drain hose 17 of the dual-cylinder module 3 along the support frame of the five-cylinder module 4, so that the drain hose 17 of the dual-cylinder module 3 passes through the through hole and leads the drain hose 17 of the dual-cylinder module 3 to the corresponding drain module. Then, pass the binding strap through the second fixing hole 19 and the third fixing hole 20 respectively to fix the drain hose 17 of the dual-cylinder module 3.

[0064] In addition, such as Figure 2As shown, in some embodiments, one of the air cylinder modules is provided with a first mounting bracket 21, on which an air passage block 22 is mounted. The air passage block 22 is provided with a test connector 23, a pressure gauge 24, and a pressure sensor 25. The air cylinder module with the first mounting bracket 21 includes an end air cylinder and an intermediate air cylinder. The intermediate air cylinder is connected to the air passage block duct 26, and the air passage block duct 26 is connected to the air passage block 22. The end air cylinder is connected to the main air hose 27, which is used to connect to the main pipeline of the maglev vehicle. In some embodiments, when there are two air cylinder modules, namely a dual air cylinder module 3 and a five air cylinder module 4, the first mounting bracket 21 is provided on the five air cylinder module 4.

[0065] It is understandable that after the air from the main air hose 27 enters the end air cylinder, it flows within each air cylinder module and enters the air passage block 22 through the air passage block duct 26. It is then detected by the test connector 23, pressure gauge 24, and pressure sensor 25. In other words, in this embodiment, the test connector 23, pressure gauge 24, and pressure sensor 25 are integrated on the first mounting bracket 21 to facilitate the monitoring and detection of pressure.

[0066] Understandably, the signal detected by pressure sensor 25 is used to control the start and stop of the air compressor in the maglev vehicle. For example, when the pressure value detected by pressure sensor 25 is lower than a first preset value, the air compressor is started; when the pressure value detected by pressure sensor 25 is higher than a second preset value, the air compressor is stopped. The pressure signal collected by pressure sensor 25 can be transmitted to the vehicle diagnostic network via a network using the air compressor inverter for pressure judgment, thereby facilitating the start and stop control of the air compressor.

[0067] Furthermore, such as Figure 2 As shown, in some embodiments, a second mounting bracket 28 is provided on the secondary cooling of the air supply device 2, and the connecting cable 29 of the pressure sensor 25 is fixed to the second mounting bracket 28.

[0068] In other words, this embodiment uses the second mounting bracket 28 on the secondary cooling of the air supply device 2 to fix the connecting cable 29 of the pressure sensor 25, so that the wiring path of the pressure sensor 25 can be connected to the air compressor inverter. It is understood that when the pressure sensor 25 is located in the middle of the first mounting bracket 21 of the air cylinder module, the connecting cable 29 of the pressure sensor 25 is not convenient to connect to the fixed bracket on the maglev vehicle body. This embodiment solves the problem of the inconvenience in fixing the connecting cable 29 of the pressure sensor 25 by setting the second mounting bracket 28 on the secondary cooling of the air supply device 2.

[0069] In addition, in order to facilitate the connection between the equipment mounting box 1 and the maglev vehicle body, in some embodiments, the equipment mounting box 1 is provided with bolt holes so that the equipment mounting box 1 can be suspended and connected to the vehicle body by bolts.

[0070] In addition to the aforementioned air supply device for maglev vehicles, this invention also provides a maglev vehicle that includes the air supply device for maglev vehicles disclosed in the above embodiments. For the structure of other parts of the maglev vehicle, please refer to the relevant technology, which will not be repeated here.

[0071] The key point of this embodiment is that the maglev vehicle adopts the maglev vehicle air source device disclosed in any of the above embodiments, and at least includes the beneficial effects of the maglev vehicle air source device, which will not be repeated here.

[0072] It should also be noted that, in this specification, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0073] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0074] The foregoing has provided a detailed description of the air supply device and maglev vehicle for maglev vehicles. Specific examples have been used to illustrate the principles and implementation methods of the invention. The descriptions of these embodiments are merely illustrative of the methods and core ideas of the invention. It should be noted that those skilled in the art can make various improvements and modifications to the invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the invention.
