Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this utility model, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-5 As shown, this embodiment provides a rotatable suspended magnetic levitation structure, including: a track beam 10, a suspension frame assembly 20, and a carriage 30. The suspension frame assembly 20 is movably engaged with the track beam 10, and a portion of the suspension frame assembly 20 is located on the side of the track beam 10 facing the ground. The suspension frame assembly 20 is adapted to move along the extension direction of the track beam 10. The carriage 30 is connected to the suspension frame assembly 20, and the suspension frame assembly 20 is adapted to drive the carriage 30 to rotate in the horizontal direction.

[0028] In some embodiments, the track beam 10 serves as the basic support component of the entire rotatable suspended magnetic levitation structure. The track beam 10 provides a track for the installation and operation of the suspension frame assembly 20 and the carriage 30. The suspension frame assembly 20 is movably engaged with the track beam 10, and a portion of the suspension frame assembly 20 is located on the side of the track beam 10 facing the ground. The suspension frame assembly 20 has the ability to move along the extension direction of the track beam 10. Thus, the suspension frame assembly 20 can drive the carriage 30 connected to it to travel along the route laid on the track beam 10. The carriage 30 is connected to the suspension frame assembly 20 and is suspended below the track beam 10 by the suspension frame assembly 20. The suspension frame assembly 20 can drive the carriage 30 to move along the extension direction of the track beam 10, and at the same time, the suspension frame assembly 20 can drive the carriage 30 to rotate relative to the track beam 10 in the horizontal direction.

[0029] It is understandable that the design of the connection between the suspension frame assembly 20 and the track beam 10 adopts a connection method similar to that between a rail train and the track, which can be achieved through technologies such as pulleys, guide rails or magnetic levitation, and there are no restrictions here.

[0030] The suspension frame assembly 20 is equipped with a dedicated rotation drive device, such as a motor or gear transmission system, which is not limited here. The rotation drive device can drive the carriage 30 to rotate horizontally around a vertical axis. At the same time, the rotation drive device can precisely adjust the speed and direction of the carriage 30's rotation, enabling the carriage 30 to rotate flexibly at different angles.

[0031] According to the rotatable suspended magnetic levitation structure of this utility model, the suspension frame assembly 20 can drive the carriage 30 to move along the extension direction of the track beam 10, while the suspension frame assembly 20 can also drive the carriage 30 to rotate in the horizontal direction, so that passengers can enjoy the surrounding scenery in all directions during the ride. Whether it is urban scenery, natural landscape or specific themed scenes, they can be presented to passengers from different angles, increasing the fun and novelty of the ride.

[0032] It is worth mentioning that the rotatable suspended maglev structure of this application can also be applied to tourist attractions. In tourist attractions, the rotation angle and dwell time of the carriage 30 can be designed according to the distribution of attractions and tourist routes, so as to provide tourists with a more personalized sightseeing experience.

[0033] According to some embodiments of the present invention, the suspension frame assembly 20 includes a connecting frame that cooperates with the track beam 10. A first driving member is provided on the side of the connecting frame facing the ground. The first driving member has a rotatable first driving part, which is connected to the carriage 30 and adapted to drive the carriage 30 to rotate.

[0034] In some embodiments, the first drive member is installed on the side of the connecting frame facing the ground, and the first drive part of the first drive member is connected to the carriage 30. The operation of the first drive member can drive the carriage 30 to rotate through the first drive part.

[0035] According to some embodiments of the present invention, the first driving component includes a rotating motor 221, the output shaft of the rotating motor 221 is provided with a driving gear 222, the driving gear 222 meshes with an internal gear ring 223, the internal gear ring 223 is connected to the carriage 30, the internal gear ring 223 is constructed as the first driving part, and a connecting ring 224 is rotatably sleeved on the outer circumference of the internal gear ring 223, and the connecting ring 224 is connected to the connecting frame.

[0036] In some embodiments, the rotating motor 221 is connected to the connecting frame and serves as the power source for the rotation of the carriage 30. The output shaft of the rotating motor 221 is provided with a drive gear 222. The internal gear ring 223 meshes with the drive gear 222 to form a gear transmission relationship. When the drive gear 222 rotates, it will drive the internal gear ring 223 to rotate in the opposite direction, thereby driving the carriage 30 connected to the internal gear ring 223 to rotate.

[0037] Understandably, after the rotating motor 221 is started, the output shaft of the rotating motor 221 begins to rotate and drives the drive gear 222 fixed on the output shaft to rotate synchronously. Since the drive gear 222 meshes with the internal gear ring 223, the rotation of the drive gear 222 will drive the internal gear ring 223 to rotate in the opposite direction. The rotation of the internal gear ring 223 is transmitted to the carriage 30 through the connection with the carriage 30, thereby causing the carriage 30 to rotate.

[0038] It is worth mentioning that the connecting ring 224 is rotatably connected to the internal gear ring 223, and the connecting ring 224 is connected to the connecting frame. Thus, the connecting ring 224 provides stable installation conditions for the internal gear ring 223, so that the internal gear ring 223 can rotate stably relative to the connecting frame, thereby ensuring that the carriage 30 can rotate stably in the horizontal direction.

[0039] Of course, the internal gear ring 223 is rotatably set inside the connecting ring 224, which not only achieves the support and positioning of the internal gear ring 223, but also does not occupy too much space. This is conducive to the installation and layout of the rotatable suspension magnetic levitation structure in a limited space, making full use of space and making the structure of the first driving component more compact.

[0040] According to some embodiments of the present invention, the outer peripheral wall of the internal gear ring 223 is provided with a first mating groove that extends in the circumferential direction and is open in the radial direction, and the inner peripheral wall of the connecting ring 224 is provided with a second mating groove that extends in the circumferential direction and is open in the radial direction. The first mating groove and the second mating groove are opposite to each other and together define a receiving space, and a limiting ring 225 is received in the receiving space.

[0041] In some embodiments, the first mating groove is an annular groove structure with a certain depth and width surrounding the outer periphery of the internal gear ring 223. Similarly, the second mating groove is an annular groove structure with a certain depth and width surrounding the inner periphery of the connecting ring 224. When the internal gear ring 223 is assembled with the connecting ring 224, the first and second mating grooves are aligned, and the space between the first and second mating grooves together constitutes a receiving space. The limiting ring 225 is placed in the receiving space to restrict the relative movement of the internal gear ring 223 and the connecting ring 224. Specifically, the limiting ring 225 can restrict the relative movement of the internal gear ring 223 and the connecting ring 224 in the axial direction, so that the internal gear ring 223 only has the degree of freedom of rotation relative to the connecting ring 224, thereby allowing the carriage 30 to rotate stably in the horizontal direction.

[0042] It is worth mentioning that during assembly, simply place the limiting ring 225 into the receiving space formed by the first and second mating grooves, and then assemble the internal gear ring 223 with the connecting ring 224. Furthermore, if any of the limiting ring 225, internal gear ring 223, or limiting ring 224 is damaged, the corresponding limiting ring 225, internal gear ring 223, or limiting ring 225 can be repaired or replaced, reducing repair and replacement costs.

[0043] According to some embodiments of the present invention, the connecting frame includes a first connecting plate 211, which is connected to a first driving member. The first connecting plate 211 is connected to a connecting arm 212 extending in the height direction, and the free end of the connecting arm 212 is adapted to cooperate with the track beam 10.

[0044] In some embodiments, the first connecting plate 211 provides an installation position for the first driving component. By connecting the first connecting plate 211 with the first driving component, the first driving component can be securely fixed on the connecting frame, enabling the first driving component to work normally and drive the carriage 30 to rotate. The free end of the connecting arm 212 refers to the end of the connecting arm 212 away from the first connecting plate 211. The free end of the connecting arm 212 has a specific shape or structure and can cooperate with the track beam 10, thereby realizing the connection between the connecting frame and the track beam 10, so that the carriage 30 can be stably suspended below the track beam 10.

[0045] According to some embodiments of the present invention, a damping member 213 is provided on the top of the first connecting plate 211, a crossbeam 214 is provided on the top of the damping member 213, and longitudinal frames 215 extending toward the carriage 30 are provided at both ends of the crossbeam 214. The free ends of the two longitudinal frames 215 are connected to the second connecting plate 216, and the second connecting plate 216 is rotatably connected to the carriage 30.

[0046] In some embodiments, the damping element 213 may be a spring damper, a hydraulic damper, a rubber damper, or an air spring, etc., and there is no limitation herein. The damping element 213 can absorb the vibration transmitted from the first connecting plate 211 to the carriage 30, thereby improving the ride comfort.

[0047] Specifically, a damping component 213 is installed above the first connecting plate 211. The damping component 213 serves to buffer and absorb vibration energy. The horizontal frame 214 is placed horizontally on the damping component 213 as an intermediate transition structure connecting the vertical frame 215. The two ends of the horizontal frame 214 are respectively connected to the vertical frame 215. The free ends of the vertical frame 215 are respectively connected to the second connecting plate 216. The second connecting plate 216 is fixedly connected to the connecting ring 224.

[0048] It is understandable that the second connecting plate 216 is fixedly connected to the connecting ring 224, the carriage 30 is fixedly connected to the internal gear ring 223, and the connecting ring 224 and the internal gear ring 223 are rotatably connected through the limiting ring 225, thereby realizing the rotatable connection between the second connecting plate 216 and the carriage 30.

[0049] Preferably, multiple vibration damping elements 213 are provided at intervals along the extension direction of the crossbeam 214. The multiple vibration damping elements 213 can jointly absorb the vibration transmitted from the first connecting plate 211 to the carriage 30, so that the vibration damping effect of the carriage 30 is better.

[0050] According to some embodiments of the present invention, the track beam 10 includes at least one longitudinal beam 11, and a first crossbeam 12 and a second crossbeam 13 are respectively provided on both sides of the at least one longitudinal beam 11 in the height direction. The first crossbeam 12 is located above the second crossbeam 13. A second driving member is provided at one end of the connecting arm 212 away from the carriage 30. The second driving member is adapted to cooperate with the second crossbeam 13 and / or the longitudinal beam 11.

[0051] In some embodiments, at least one longitudinal beam 11 has a first crossbeam 12 and a second crossbeam 13 respectively provided on both sides in the height direction. The first crossbeam 12, the second crossbeam 13, and at least one longitudinal beam 11 together form an "I"-shaped track beam 10 structure. Connecting arms 212 are provided at both ends of the first connecting plate 211. The two connecting arms 212 are located on both sides of the longitudinal beam 11, and each connecting arm 212 cooperates with either the second crossbeam 13 or the longitudinal beam 11. Therefore, the above arrangement ensures the stress stability of the first connecting plate 211, thereby ensuring the stability of the connection between the carriage 30 and the track beam 10.

[0052] According to some embodiments of the present invention, the second driving component includes a mounting beam 231, the extension direction of the mounting beam 231 is parallel to the extension direction of the track beam 10, the mounting beam 231 is located between the first crossbeam 12 and the second crossbeam 13, a levitation device 232 is provided on the side of the mounting beam 231 facing the second crossbeam 13, and a permanent magnet track structure 131 is provided on the side of the second crossbeam 13 facing the first crossbeam 12, with the levitation device 232 and the permanent magnet track structure 131 facing each other.

[0053] In some embodiments, the levitation device 232 is disposed on the side of the mounting beam 231 facing the second crossbeam 13. The levitation device 232 may be a Dewar. The levitation device 232 is used to accommodate and support components such as superconducting magnets and to provide a low-temperature environment for the superconducting magnets to ensure their superconducting performance. The permanent magnet track structure 131 may be a permanent magnet plate. The permanent magnet track structure 131 is disposed on the side of the second crossbeam 13 facing the first crossbeam 12. The laying direction of the permanent magnet track structure 131 is parallel to the extension direction of the track beam 10. The levitation device 232 and the permanent magnet track structure 131 are directly opposite each other in the height direction. The permanent magnet track structure 131 can provide a stable magnetic field, which interacts with the magnetic field generated by the superconducting magnet in the levitation device 232, thereby realizing functions such as driving or levitation (superconducting pinned magnetic levitation effect).

[0054] It should be noted that the above-mentioned arrangement also enables the carriage 30 to have guiding properties, that is, the carriage 30 can always move along the extension direction of the track beam 10, and ensure that there is no contact between the suspension frame assembly 20 and the track beam 10, thereby avoiding wear between the track beam 10 and the suspension frame assembly 20 and extending the service life of the rotatable suspension magnetic levitation structure.

[0055] According to some embodiments of the present invention, the second driving component further includes a first emergency wheel 233 and a second emergency wheel 234. The first emergency wheel 233 is connected to the mounting beam 231 and can optionally cooperate with the second crossbeam 13. The second emergency wheel 234 is connected to the mounting beam 231 and can optionally cooperate with the longitudinal beam 11.

[0056] In some embodiments, under normal maglev operation, the first emergency wheel 233 does not contact the second crossbeam 13; however, under specific emergency conditions, the first emergency wheel 233 will cooperate with the second crossbeam 13 to play a corresponding emergency role.

[0057] Specifically, in normal maglev operation mode, the superconducting pinned maglev effect suspends the carriage 30 and maintains stable operation. At this time, the first emergency wheel 233 is suspended and does not contact the second crossbeam 13. When special circumstances occur, such as a superconducting system failure or power outage causing the maglev effect to fail, the carriage 30 loses its levitation force and begins to fall. At this point, the first emergency wheel 233 gradually approaches and eventually contacts the second crossbeam 13, achieving a switch from maglev operation mode to emergency wheel-supported operation mode. The use of the first emergency wheel 233 can prevent serious safety accidents or equipment damage caused by sudden falls. Simultaneously, the first emergency wheel 233 can also prevent the levitation device 232 from directly contacting the permanent magnet track structure 131, thereby avoiding damage to the levitation device 232.

[0058] Of course, when the carriage 30 or the suspension frame assembly 20 needs maintenance, the presence of the first emergency wheel 233 will also prevent the suspension 232 from directly contacting the permanent magnet track structure 131, thereby facilitating the maintenance of the suspension 232 and preventing the suspension 232 from bearing the weight of the carriage 30, thus preventing damage to the suspension 232.

[0059] In some embodiments, when the carriage 30 is running and experiencing strong lateral winds, the second emergency wheel 234 can cooperate with the longitudinal beam 11 to achieve auxiliary guidance, while preventing the suspension 232 from directly contacting the longitudinal beam 11, thereby preventing the suspension 232 and the track beam 10 from wearing each other, improving the operating safety factor of the carriage 30 and the service life of the rotatable suspension magnetic levitation structure.

[0060] According to some embodiments of the present invention, a first traction part 132 is provided on the side of the second crossbeam 13 facing the carriage 30, and a second traction part 235 is provided on the side of the first connecting plate 211 facing the track beam 10. The first traction part 132 and the second traction part 235 cooperate to provide driving force for the carriage 30 so as to drive the carriage 30 to move along the extension direction of the track beam 10.

[0061] It is understandable that the first traction unit 132 and the second traction unit 235 cooperate through a specific electromagnetic structure, that is, they use electromagnetic force to interact and achieve traction. When the first traction unit 132 is driven by an external power source, the first traction unit 132 will interact with the second traction unit 235, transmitting power to the second traction unit 235, thereby generating a traction force to move the carriage 30.

[0062] In some embodiments, the first traction unit 132 is constructed as an aluminum induction plate laid along the extension direction of the track beam 10, and the second traction unit 235 is constructed as a coil. When an alternating current is passed through the coil of the second traction unit 235, an alternating magnetic field is generated around the coil according to the law of electromagnetic induction. Since the first traction unit 132 is an aluminum induction plate laid along the extension direction of the track beam 10, when the carriage 30 drives the coil to move, causing the coil to approach or move away from the aluminum induction plate, the aluminum induction plate will be in the alternating magnetic field. According to the mutual inductance phenomenon of electromagnetic induction, an induced electromotive force and an induced current, i.e., eddy current, will be generated in the aluminum induction plate.

[0063] The eddy currents generated in the aluminum induction plate will form a magnetic field that interacts with the magnetic field of the coil. According to Ampere's law, these two magnetic fields will generate an interaction force, namely electromagnetic force. Electromagnetic force is the driving force that drives the carriage 30 to move. The direction of electromagnetic force is related to the direction of movement of carriage 30. By controlling the frequency, phase and other parameters of the alternating current in the coil, the magnitude and direction of electromagnetic force can be precisely controlled, thereby realizing the driving and control of the movement of carriage 30.

[0064] In the above scheme, the track beam 10 is equipped with a power supply rail, the extension direction of which is parallel to the extension direction of the track beam 10. The mounting beam 231 is equipped with a current collector, which cooperates with the power supply rail and is electrically connected to the coil. Thus, the power supply rail and the current collector can cooperate to supply power to the coil, thereby ensuring that the carriage 30 can move along the extension direction of the track beam 10.

[0065] In other embodiments, the first traction unit 132 is constructed as a coil arranged along the extension direction of the track beam 10, and the second traction unit 235 is constructed as a permanent magnet. The permanent magnet itself has a stable magnetic field. When the carriage 30 moves the permanent magnet, causing the permanent magnet to approach or move away from the coil, the magnetic field of the permanent magnet will pass through the coil. According to Faraday's law of electromagnetic induction, when the magnetic flux in the coil changes, an induced electromotive force will be generated in the coil, accompanied by an induced current.

[0066] The induced current generated in the coil creates a magnetic field that interacts with the permanent magnet's magnetic field. According to Ampere's law, these two magnetic fields generate an interaction force, namely the electromagnetic force. This electromagnetic force is the driving force that propels the carriage 30. By designing the number of turns and winding method of the coil, as well as the magnetic field strength and distribution of the permanent magnet, the magnitude and direction of the electromagnetic force can be precisely controlled, thereby achieving the driving and control of the carriage 30's movement. For example, when the carriage 30 needs to accelerate, relevant parameters can be adjusted to make the electromagnetic force's direction the same as the carriage 30's direction of movement and its magnitude increased; when the carriage 30 needs to decelerate, the electromagnetic force's direction is adjusted to be opposite to the carriage 30's direction of movement.
