[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on 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.

[0044] The core of the present invention is to provide a train system with a higher level of comfort.

[0045] For a specific embodiment of the train system provided by the present invention, please refer to Figures 1 to 16 , including a vehicle 1, a track 3, a platform system 4 and an escape system.

[0046] The vehicle 1 includes a vehicle body 2, which may include one or more vehicle bodies 2. The vehicle body 2 may be made of an aluminum alloy or a carbon fiber composite structure. Figure 1 and Figure 2 As shown, the vehicle 1 includes two vehicle bodies 2, which are arranged in sequence along the front-to-back direction and are arranged in mirror symmetry. Figure 5 As shown, the two car bodies 2 are connected by a coupler 26. The two car bodies 2 can each have a passenger compartment and a driver's cab, and the vehicle can run in both directions.

[0047] In each vehicle body 2, if Figure 2 , Figure 6 and Figure 7 As shown, the car body 2 includes an upper compartment 21 and a lower compartment 22 fixed to the lower layer of the upper compartment 21. Specifically, the car body 2 can be integrally formed. The upper compartment 21 and the lower compartment 22 can be arranged in mirror symmetry. Among them, inside the car body 2, an in-car ladder can also be arranged between the upper compartment 21 and the lower compartment 22, so that passengers can reach the lower compartment 22 from the upper compartment 21. Of course, the upper compartment 21 and the lower compartment 22 may not be directly connected, and it is necessary to reach another compartment from one compartment outside the car. In this embodiment, the car body 2 has only a double-decker compartment. In other embodiments, it can also be more than a double-decker compartment, such as a three-decker compartment. Specifically, a top compartment can be added to the upper compartment 21 in this embodiment. At this time, the top compartment can be connected to the upper compartment 21 through an elevator.

[0048] like Figure 3 , Figure 6 and Fig.10 As shown, a mezzanine 24 is provided between the upper carriage 21 and the lower carriage 22, and a bogie 23 is provided in the mezzanine 24. The two ends of the bogie 23 in the transverse direction X extend out of the upper carriage 21 and the lower carriage 22 respectively, and respectively form support parts 231 for connection to the track 3.

[0049] It should be noted that the transverse direction X usually corresponds to the width direction of the vehicle body 2 , and the longitudinal direction Y usually corresponds to the length direction of the vehicle body 2 . Specifically, the transverse direction X, the longitudinal direction Y and the up-down direction are perpendicular to each other.

[0050] For the convenience of passengers to choose the vehicle body 2 for entering and exiting, such as Figure 2 As shown, the doors of the two car bodies 2 can be arranged on the sides of the car ends that are connected to each other. Specifically, an upper door 212 that can be opened and closed is arranged on the upper compartment 21 of the car body 2, and an openable and closable lower door 221 is arranged on the lower compartment 22. The upper door 212 and the lower door 221 in one car body 2 are respectively arranged on the sides close to the end of the other car body 2, and the upper door 212 and the lower door 221 on one car body 2 are aligned up and down.

[0051] The track 3 extends along a preset direction of travel, and can specifically extend along a straight line or an arc. Figure 1 As shown, two rails 3 are provided, which are respectively provided on both sides of the vehicle body 2 in the transverse direction X. Figure 3 As shown, the track 3 has a track groove 31 facing the vehicle body 2. Specifically, the track groove 31 may have only one notch facing the vehicle body 2 in the transverse direction. In this case, the notches of the track grooves 31 of the two tracks 3 are arranged opposite to each other in the transverse direction X.

[0052] like Figure 3 As shown, the two support parts 231 at both ends of the bogie 23 in the transverse direction X extend into the corresponding track grooves 31 respectively, and the support parts 231 can move in the track grooves 31. Specifically, a running component can be provided on the support parts 231. During the movement of the vehicle 1, the support parts 231 can move in the track grooves 31, so that the track grooves 31 can support and guide the bogie 23 during the movement by cooperating with the movement of the support parts 231.

[0053] The train system in this embodiment includes a vehicle 1 with double-decker carriages, which can carry passengers in layers, increase the passenger capacity that can be received in a single operation, and effectively solve the problems of urban traffic congestion and insufficient transportation capacity. It is suitable for areas with concentrated passenger flow and large passenger demand. The track 3 is a groove structure, and the bogie 23 on the vehicle 1 can be installed in an embedded manner on the track 3. While ensuring the smooth operation, the risk of derailment of the vehicle 1 can be avoided, the operation safety is high, and the travel comfort is good.

[0054] Furthermore, a magnetic levitation device is provided between the support portion 231 and the track groove 31, and the vehicle 1 can specifically cooperate with the track 3 to form a conventional magnetic levitation train. At this time, the vehicle 1 is a magnetic levitation train, and the bogie 23 constitutes a suspension frame, which is suspended in the track groove 31 during operation. Through the magnetic levitation cooperation, the resistance during the travel process can be reduced, and the running stability and comfort can be improved. Of course, in other embodiments, the train system can be compatible with multiple systems, such as wheel-rail, rubber wheel, permanent magnet system, etc.

[0055] Specifically, in order to realize the driving of the vehicle 1, the vehicle 1 is driven by a linear motor. On the track 3, the long stators are respectively located at the upper part, the lower part and the side part of the track groove 31, and the traveling wave magnetic field drives the vehicle 1 to run at the same speed as the air gap magnetic field.

[0056] In a magnetic levitation device, Figure 3 and Figure 4 As shown, it includes an electromagnet module 232 disposed on a support portion 231 and a stator winding 32 disposed in a track groove 31, wherein the stator winding 32 includes a coil. When the stator winding 32 is energized, a magnetic field can be formed with the electromagnet module 232 on the suspension frame of the vehicle 1.

[0057] Specifically, Figure 4 As shown, the stator windings 32 arranged on the top, bottom and side surfaces of the track groove 31 are the first stator winding 321, the second stator winding 322 and the third stator winding 323 in sequence; the electromagnet module 232 includes the first electromagnetic part 2321, the second electromagnetic part 2322 and the third electromagnetic part 2323 arranged on the top, bottom and side surfaces of the support part 231 in sequence. The first electromagnetic part 2321 is used to cooperate with the first stator winding 321 to attract each other, the second electromagnetic part 2322 is used to cooperate with the second stator winding 322 to repel each other, and the first electromagnetic part 2321 is used to cooperate with the first stator winding 321 to repel each other.

[0058] At this time, a groove-embedded track structure is adopted. When the vehicle 1 is suspended on the track 3, there is suction between the upper part of the suspension frame and the track 3, and repulsion between the lower part and the track 3, which can provide the vehicle 1 with greater suspension force and traction force, and this train system has low use cost and good maintainability.

[0059] Specifically, in the electromagnet module 232, the first electromagnet part 2321, the second electromagnet part 2322 and the third electromagnet part 2323 are electromagnet coils, and each electromagnet coil is designed as a separate circuit, and the current direction and size of the electromagnet coil can be changed arbitrarily. In addition, gap sensors can be respectively provided on the upper part, the lower part and the outer part of the electromagnet module 232 to monitor the gap between the track groove 31 in the three directions of the upper part, the lower part and the lateral part on the horizontal X in real time, so as to facilitate the control and adjustment of the gap in the corresponding direction. At this time, since the electromagnet coils in each part can control the current direction and size individually, and then control the size of the force in the three directions, the adaptability to the line is stronger, and the vehicle 1 can specifically run in both directions.

[0060] Exemplarily, the first electromagnetic part 2321, the second electromagnetic part 2322 and the third electromagnetic part 2323 may have the same magnetic poles. Figure 4 As shown, in a specific magnetic levitation matching position of the vehicle 1 and the track 3, the first electromagnetic part 2321, the second electromagnetic part 2322 and the third electromagnetic part 2323 are respectively S poles, and correspondingly, the first stator winding 321 is an N pole, the second stator winding 322 is an S pole, and the third stator winding 323 is an N pole. Of course, in another embodiment, the above-mentioned N pole and S pole can also be reversed.

[0061] The bogie 23 includes a main frame 234, a suspension system 233 and an electromagnet module 232. The main frame 234 is installed on the interlayer 24 and is used to install the suspension system 233 and the electromagnet module 232.

[0062] Specifically, Fig.10 As shown, the main frame 234 includes two longitudinal beams 2341 and a plurality of transverse beams 2342. The transverse beams 2342 are arranged in sequence along the longitudinal direction Y, and the two ends in the transverse direction X are respectively fixed to the two longitudinal beams 2341. Figure 4 As shown, the support portion 231 includes a longitudinal beam 2341 , and the electromagnet module 232 is arranged on the longitudinal beam 2341 .

[0063] Specifically, Figures 10 to 13 As shown, each cross beam 2342 is provided with a suspension system 233, and the upper carriage 21 and the lower carriage 22 are connected respectively through the suspension system 233. Fig.11 As shown, above the cross beam 2342, the suspension system 233 includes a suspension seat 2333 and an empty spring 2331 disposed above the suspension seat 2333. The empty spring 2331 is connected to the bottom of the upper carriage 21, which can effectively prevent the vibration of the suspension frame from being transmitted to the upper carriage 21. Fig.13 As shown, below the cross beam 2342 , the suspension system 233 includes a rubber pile 2332 , and the rubber pile 2332 is connected to the top of the lower car body 22 below, so as to better suspend the weight of the lower car body 22 .

[0064] Specifically, Figure 7 As shown, the interlayer 24 is alternately provided with equipment compartments 242 and beam interfaces 241 in the longitudinal direction Y, specifically, one equipment compartment 242, one beam interface 241, one equipment compartment 242, and one beam interface 241, and the arrangement is as follows. A plurality of equipment compartments 242 are provided; a plurality of beam interfaces 241 are provided, and the number is equal to or greater than the number of beams 2342. The beam interfaces 241 and the equipment compartments 242 can both be through-hole structures penetrating in the transverse direction X. Each beam 2342 is respectively plugged into each beam interface 241, and an equipment box 25 is provided in at least one equipment compartment 242.

[0065] For the main frame 234, during the assembly process, the cross beams 2342 can be respectively plugged into the cross beam interfaces 241, that is, after the equipment box 25 is installed in the corresponding equipment compartment 242, the longitudinal beam 2341 can be connected to the cross beam 2342. For the convenience of maintenance and installation, the longitudinal beam 2341 can include a plurality of sub-beams arranged in sequence along the longitudinal direction, so as to be installed in sections on the corresponding cross beams.

[0066] Specifically, to facilitate the assembly of the equipment box 25, as Figures 7 to 9 As shown, the equipment box 25 is provided with slide rails 251 extending in the horizontal direction X on both sides in the longitudinal direction Y, and the equipment compartment 242 can be adaptively provided with slide rails corresponding to the slide rails 251 for sliding cooperation. The equipment box 25 can be installed by pushing and sliding the equipment box 25 into the equipment compartment 242 through the port in the horizontal direction X of the equipment compartment 242. The equipment box 25 is specifically a standard equipment box, and the outer box body of the standard equipment box is a unified structure, and the difference lies in the modules in the box, which can be selected according to the functional requirements of different equipment.

[0067] On track 3, such as Figures 1 to 3 , Fig.16 As shown, the track 3 includes a track body 34 and a column 35 fixed below the track body 34, a track groove 31 is provided on the track body 34, and the bottom end of the column 35 is supported above the ground 6. Specifically, the track body 34 protrudes from the side of the column 35 close to the vehicle 1 in the transverse direction X, so that the track body 34 and the column 35 constitute an F-type track 3. At this time, the track 3 is fixed above the ground 6, and the track groove 31 supports the vehicle 1 above the ground 6. Specifically, the bottom end of the vehicle 1 can be higher than the bottom end of the column 35. The vehicle 1 is a train running on the ground. Since it is a maglev train, there is no noise problem. At the same time, during construction, it is sufficient to directly select a suitable position to install and fix the column 35, without digging an underground passage, which is convenient for construction, has strong environmental adaptability, and is suitable for complex terrain.

[0068] Specifically, the track body 34 extends along a preset travel direction, and in the extending direction of the track body 34, a plurality of columns 35 are sequentially arranged at intervals to ensure the support capacity. During processing, the track 3 can adopt a structure of concrete casting combined with steel structure.

[0069] To further improve the passenger experience, Figure 6 and Figure 7 As shown, viewing windows 27 are respectively provided on the upper carriage 21 and the lower carriage 22. Specifically, viewing windows 27 can be provided on the top and side of the upper carriage 21, and on the side and bottom of the lower carriage 22. The number of viewing windows 27 can be set as required, and multiple viewing windows 27 can be provided. For example, three viewing windows 27 are provided on the top of the upper carriage 21, and three viewing windows 27 are provided on the bottom of the lower carriage 22. At this time, passengers in the upper carriage 21 can enjoy the beautiful scenery of blue sky and white clouds through the viewing windows 27 on the roof, and passengers in the lower carriage 22 can experience the excitement of a glass plank bridge through the viewing windows 27 at the bottom, which can meet the riding needs of different groups of people.

[0070] The platform system 4 is arranged at a preset station location for passengers to get on and off the bus. Figures 1 to 3 As shown, the platform system 4 includes a first-floor platform 41 and a second-floor platform 42 disposed above the first-floor platform 41, a platform ladder 43 is disposed between the first-floor platform 41 and the second-floor platform 42, and the first-floor platform 41 and the second-floor platform 42 are docked with a track 3 in the horizontal direction X. The second-floor platform 42 is docked and fixed to the track body 34, and the first-floor platform 41 is docked and fixed to the column 35, so as to improve the structural strength of the track 3. In addition, the platform ladder 43 can be a walking ladder, an elevator, or an escalator, so as to facilitate passengers to get on and off the platform.

[0071] When the vehicle 1 stops at the preset station, the first-floor platform 41 is located on the side of the lower door 221 of the lower compartment 22 in the horizontal direction X, and the second-floor platform 42 is located on the side of the upper door 212 of the upper compartment 21 in the horizontal direction X. When the vehicle 1 stops, the top surface of the second-floor platform 42 is equal to or slightly lower than the bottom surface of the upper door 212. After the upper door 212 is opened, the passengers of the upper compartment 21 can walk to the second-floor platform 42; the top surface of the first-floor platform 41 is equal to or slightly lower than the bottom surface of the lower door 221. After the lower door 221 is opened, the passengers of the lower compartment 22 can walk to the first-floor platform 41. Figure 1 As shown, the first-floor platform 41 and the second-floor platform 42 can directly lead to the waiting hall respectively. After opening the boarding door 212 and the disembarking door 221, the passengers can follow the arrows on the dotted lines to the waiting hall. Passengers on the second-floor platform 42 can also go down to the first-floor platform 41 via the platform ladder 43.

[0072] To improve safety, the escape system may include a first escape device, a second escape device, and a third escape device. Different escape methods may be used separately or simultaneously. By providing a variety of escape tools and methods, the safety of the vehicle 1 is greatly improved, and rapid escape and rescue are achieved. Of course, in other embodiments, the escape system may also have only one or two of the above three escape devices.

[0073] In the first escape device, if Figure 5 and Fig.14 As shown, the lift 5 includes a retractable lift 5, which can be electrically retractable or manually retractable. The lift 5 can be retracted to be stored in the storage area 243 of the interlayer 24. The storage area 243 can be a partial space of an equipment compartment 242 or a partial space of a beam interface 241, or can be another space in the interlayer 24 that is independent of the beam interface 241 and the equipment compartment 242.

[0074] like Fig.14 As shown, the top of the accommodating area 243 is connected to the lower entrance 211 at the bottom of the upper compartment 21, and the bottom is connected to the upper exit 222 at the top of the lower compartment 22, and the lower exit 223 is provided at the bottom of the lower compartment 22. The lift 5 can be extended to enter the escape state. In the escape state, the lift 5 sequentially extends through the lower entrance 211, the accommodating area 243, the upper exit 222, the internal space of the lower compartment 22, and the lower exit 223 to the external space under the lower compartment 22. These areas form an escape passage 28 connected downward. With the help of the lift 5, passengers in the upper compartment 21 can enter the lower compartment 22 through the lower entrance 211, the interlayer 24, and the upper exit 222, and passengers in the lower compartment 22 can reach the outside of the vehicle through the lower exit 223.

[0075] like Figure 5 As shown, in the longitudinal direction Y, the lower entrance 211, the upper entrance 222, the lower entrance 223 and the accommodating area 243 of one vehicle body 2 are all arranged near the end of the other vehicle body 2, close to the positions of the upper door 212 and the lower door 221, which can increase the possibility of passengers getting out of the vehicle.

[0076] like Figure 5As shown, the lower opening 211 for boarding, the upper opening 222 for getting off, and the lower opening 223 for getting off are respectively provided with a cover plate 29 that can be opened and closed. Specifically, the cover plate 29 is a flip cover that can be turned up or down, and in other embodiments, it can also be a sliding cover. When there is no need to escape, the cover plate 29 covers the corresponding opening, and is opened again when escape is needed. The top of the lift 5 can be fixed to the bottom surface of the upper compartment 21. When an emergency occurs, the cover plates 29 of the lower opening 211 for boarding, the upper opening 222 for getting off, and the lower opening 223 for getting off can be opened in sequence, and then the lift 5 can be lowered to the bottom, wherein the height of the lift 5 can be automatically adjusted according to the height of the ground 6 to ensure that the passengers can continue to go down until they reach the ground 6 after arriving at the lower compartment 22.

[0077] In order to improve the reliability of escape, detection devices are respectively arranged at the boarding lower opening 211 and the disembarking lower opening 223, which may be infrared detection devices or pressure sensors. When the detection devices receive a preset escape signal and the detection devices respectively detect that there is no one at the boarding lower opening 211 and the disembarking lower opening 223, each cover plate 29 is opened, and the lift 5 is extended to enter the escape state, ensuring that before the cover plate 29 is opened or ready to be opened, the passenger standing on the cover plate 29 causes the passenger to fall or affect the opening action of the cover plate 29.

[0078] In the second escape device, if Fig.15 and Fig.16 As shown, it includes lower doors 221 arranged at both ends of the lower compartment 22 in the transverse direction X, and the bottom ends of the lower doors 221 can be connected to the lower compartment 22 in a downward and outward manner. The arrangement of the lower doors 221 provides a side door escape method. In an emergency, passengers and rescuers can open the lower doors 221 from inside the lower compartment 22, respectively. After the lower doors 221 are turned downward and outward to form a certain angle with the ground 6, an inclined lower slide plate is formed, and passengers can slide to the ground 6 by sliding.

[0079] Specifically, the bottom end of the exit door 221 can be hinged to the exit of the lower compartment 22 through a first hinge device, and one side in the longitudinal direction Y can be hinged to the exit of the lower compartment 22 through a second hinge device. The first hinge device and the second hinge device can be switched to allow staff or passengers to choose the door opening direction as needed. For example, when the vehicle 1 stops at the corresponding first-floor platform 41, the exit door 221 can be opened sideways; when encountering a dangerous situation, the exit door 221 can be flipped down and the top can be against the ground 6, which can be used as an escape slide.

[0080] In addition, referring to the side door escape method provided by the above-mentioned lower door 221, the upper door 212 can also be arranged in the same manner on the upper compartment 21. The difference is that, at this time, the upper door 212 can be arranged as a door panel that can be retracted up and down, so that when used for escape, it can be extended while flipping down, so that the upper door 212 can be against the ground 6.

[0081] The third escape device includes an inflatable slide. The inflatable slide can be movably arranged in the upper compartment 21 and the lower compartment 22, or can be connected to the upper compartment 21 or the lower compartment 22. For example, the inflatable slide can be directly connected to the upper door 212 and the lower door 221, so as to extend the length of the upper door 212 and the lower door 221 that are turned down through the inflatable slide to control the inclination of the lower slide plate formed for escape; or, it can be connected to the upper door 212, the lower door 221 or the viewing window 27. Due to the different heights from the ground 6, the length of the inflatable slide selected at different positions is also different. Under normal conditions, the inflatable slide is in an airless, retracted standby state; in a specific escape process, after receiving a background signal or a manual trigger button, the corresponding door or viewing window 27 is opened, and the corresponding inflatable slide is inflated and continuously extended to the outside of the vehicle 1, and can be specifically supported on the ground 6 for people to slide down the inflated inflatable slide.

[0082] In a specific escape plan, when the train system fails and cannot operate and passengers need to escape, the driver presses the emergency escape button on the console when someone is driving, or the backstage control room starts the emergency escape program when the train is fully automatic, and the passenger compartment PIS system will issue an escape voice broadcast, and the passengers in the upper carriage 21 and the lower carriage 22 will stay away from the escape exit, including the upper carriage exit 211 and the lower carriage exit 223. When the detection device on the cover plate 29 of the escape exit detects that there is no one, each cover plate 29 is automatically opened, and the elevator 5 is automatically lowered to the ground 6; when there are many passengers and the escape requirements cannot be met by the elevator 5 alone, the driver and passengers can open the emergency inflatable escape cabin button above the door, and the upper door 212 and the lower door 221 will flip down, and the inflatable slide will automatically inflate and open and extend to the ground 6 or the platform height. Passengers with limited mobility and children can escape through this plan.

[0083] The train system provided by the present embodiment has the following advantages: the conventional magnetic levitation technology is adopted, and the upper and lower panoramic sunroofs are designed. There is no wheel-rail vibration noise generated by the wheel-rail contact during driving. At the same time, passengers can enjoy the blue sky and white clouds and the beautiful scenery of the ground 6 during the journey, which has good technology and comfort. Through the cooperation of the embedded suspension frame and the F-type track 3, the vehicle 1 can maintain absolute safety even in bad weather conditions; the upper and lower double-decker carriages can provide more abundant passenger space, and the unique F track 3 design and the three-sided magnetic pole design of the suspension frame greatly improve the load capacity and traction of the train, allowing the train to adapt to more complex routes.
