DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In order to make the technical solutions and advantages of this application clearer, they will be described in detail below with reference to the drawings.

[0049] Magnetic levitation vehicles are flexible to drive and can adapt to various scenarios in urban life. Magnetic levitation vehicles in related technologies generally provide a magnetic field by attaching magnets or other magnetic components to the wheels. When the wheels rotate, they can generate a time-varying magnetic field. The magnetic lines of force cut through the induction lanes and form an induced current in the induction lanes, thereby providing levitation force for the vehicle, enabling the maglev vehicle to levitate and move forward. However, in the initial state of the maglev vehicle, the wheels are in contact with the induction lanes. Due to friction, direct rotation will wear the wheels and cannot generate sufficient levitation force to levitate the vehicle. Therefore, maglev vehicles in related technologies are generally equipped with a lifting mechanism. Before the maglev vehicle is suspended, the lifting mechanism is first used to "lift" the maglev vehicle. After the wheels are suspended, the wheels are controlled to rotate. When the wheels provide sufficient levitation force, the lifting mechanism is retracted. The entire levitation process is complex and time-consuming, and the levitation start-up speed is slow.

[0050] In this regard, the present application provides a magnetic levitation vehicle chassis, such as Figure 1 As shown, the magnetic levitation vehicle chassis may include a frame 1, two first wheel hubs 2, two second wheel hubs 3, two first support members 4 and two second support members 5; the frame 1 includes a front axle 11 and a rear axle 12 spaced apart along the length direction of the vehicle, the front axle 11 is sleeved with two first support members 4 spaced apart, and the rear axle 12 is sleeved with two second support members 5 spaced apart; a first wheel hub 2 is provided on the inner side of each first support member 4, the first wheel hub 2 is rotatably connected to the front axle 11, and can generate a magnetic field when the first wheel hub 2 rotates, a second wheel hub 3 is provided on the inner side of each second support member 5, the second wheel hub 3 is rotatably connected to the rear axle 12, and can generate a magnetic field when the second wheel hub 3 rotates; wherein, the outer edge diameter of the first wheel hub 2 is smaller than the outer edge diameter of the first support member 4, and the outer edge diameter of the second wheel hub 3 is smaller than the outer edge diameter of the second support member 5.

[0051] In the magnetic levitation vehicle chassis provided in the embodiment of the present application, a first hub 2 is provided on the front axle 11, and a second hub 3 is provided on the rear axle 12. The first hub 2 and the second hub 3 can generate a magnetic field when rotating, that is, during the rotation of the first hub 2 and the second hub 3, if an induction plate (such as a metal plate) is provided on or in the road surface, the time-varying magnetic field generated by the hub will cut the induction plate, thereby forming an induced current in the induction plate. According to the principle of electromagnetic induction and Lenz's law, an electromagnetic force will be generated between the induced magnetic field generated by the induced current and the original magnetic field to hinder this relative motion. The vertical performance is a suspension force to suspend the vehicle, and the longitudinal performance is a driving force to drive the vehicle forward, thereby realizing the vehicle. Suspension and movement; and, compared with the related art, which requires first lifting the entire vehicle through a lifting mechanism and then controlling the rotation of the wheels to obtain suspension force, the present application is provided with a first support member 4 on the outside of the first hub 2, and the radial dimension of the first support member 4 is larger than that of the first hub 2, and a second support member 5 is provided on the outside of the second hub 3, and the radial dimension of the second support member 5 is larger than that of the first hub 2, that is, in the initial state, due to the provision of the first support member 4 and the second support member 5, the first hub 2 and the second hub 3 are already in a suspended state, and can directly rotate after obtaining the suspension command of the host, without waiting for the entire vehicle body to be suspended before rotating, and the starting speed will be faster.

[0052] Optionally, the difference between the outer diameter of the first support member 4 and the outer diameter of the first hub 2 is greater than or equal to 8 mm; and / or the difference between the outer diameter of the second support member 5 and the outer diameter of the second hub 3 is greater than or equal to 8 mm.

[0053] Alternatively, the sensing plate may be a copper plate, an aluminum plate, or other metal plates with good electrical conductivity, and those skilled in the art may select and adjust the plate according to actual needs.

[0054] In some embodiments of the present application, Figure 2 As shown, the first hub 2 includes a first stator portion 21 and a first rotor portion 22 which are sleeved on the front axle 11, the first stator portion 21 is fixedly connected to the front axle 11, the first rotor portion 22 is located on the inner side of the first stator portion 21, and can rotate relative to the first stator portion 21; and / or, the second hub 3 includes a second stator portion 31 and a second rotor portion 32 which are sleeved on the front axle 11, the second stator portion 31 is fixedly connected to the rear axle 12, the second rotor portion 32 is located on the inner side of the second stator portion 31, and can rotate relative to the second stator portion 31.

[0055] In the magnetic levitation vehicle chassis provided in the embodiment of the present application, the first wheel hub 2 includes a first stator part 21 and a first rotor part 22. When a levitation command is received, current is passed through the winding on the first stator part 21, and the first stator part 21 generates a magnetic field, interacts with the first rotor part 22, and drives the first rotor part 22 to rotate. At this time, the first rotor part 22 rotates relative to the first stator part 21 and generates a time-varying magnetic field. The time-varying magnetic field interacts with the magnetic field generated at the induction plate, thereby realizing the levitation and movement of the vehicle; the principle of the second stator part 31 is the same as that of the first stator part 21, and will not be elaborated here.

[0056] It should be noted that the magnetic levitation vehicle chassis may further include a power supply device, which is electrically connected to the windings in the first stator part 21 and the second stator part 31 and supplies power to the first stator part 21 and the second stator part 31 after startup.

[0057] Optionally, the power supply device may be a vehicle-mounted power supply.

[0058] In some embodiments of the present application, Figure 2 As shown, the first rotor part 22 may include a first rotor disk 221 and a plurality of first magnets 222, and the plurality of first magnets 222 are attached to the outer peripheral wall of the first rotor disk 221. The first hub 2 also includes a first rolling bearing 23, and the first rolling bearing 23 is connected between the first rotor disk 221 and the first stator part 21; and / or, the second rotor part 32 includes a second rotor disk 321 and a plurality of second magnets 322, and the plurality of second magnets 322 are attached to the outer peripheral wall of the second rotor disk 321. The first hub 2 also includes a second rolling bearing 33, and the second rolling bearing 33 is connected between the second rotor disk 321 and the second stator part 31.

[0059] In the magnetic levitation vehicle chassis provided in the embodiment of the present application, the first rotor disk 221 is rotatably connected to the first stator part 21 through the first rolling bearing 23. When the winding on the first stator part 21 is energized, a magnetic field is generated. This magnetic field interacts with the magnetic field generated by the multiple first magnets 222 attached to the first rotor disk 221, forcing the first rotor part 22 to rotate, and then the time-varying magnetic field generated by the multiple first magnets 222 cyclically cuts the induction plate. The time-varying magnetic field interacts with the magnetic field generated at the induction plate, thereby realizing the suspension and movement of the vehicle; the principle of the second rotor part 32 is the same as that of the first rotor part 22, and will not be elaborated here.

[0060] Alternatively, the first magnet 222 may be a magnetic component such as a magnetic steel, a neodymium iron boron permanent magnet, or the like; and / or the second magnet 322 may be a magnetic component such as a magnetic steel, a neodymium iron boron permanent magnet, or the like. Those skilled in the art may select and adjust the material and quantity of the first magnet 222 and / or the second magnet 322 based on actual needs.

[0061] In some embodiments of the present application, each first support member 4 is rotatably connected to the front axle 11, and can generate a magnetic field when the first support member 4 rotates; and / or, each second support member 5 is rotatably connected to the rear axle 12, and can generate a magnetic field when the second support member 5 rotates, and the rotation direction of the second support member 5 is opposite to the rotation direction of the first support member 4.

[0062] When the maglev vehicle needs to be suspended, the first and second hubs 2 and 3 can be controlled to rotate, so that the entire maglev vehicle is suspended. At this time, in order to provide greater levitation force, make the maglev vehicle more stable, and increase travel speed, the first support member 4 and / or the second support member 5 in the maglev vehicle chassis provided in the embodiment of the application can also rotate, and can also generate a magnetic field during rotation. After the maglev vehicle is already in the suspended state, the user can choose whether to activate the first support member 4 and / or the second support member 5 according to actual needs.

[0063] In addition, when the magnetic levitation vehicle in the related art is in a suspended state, if it wants to turn to change the direction of travel, it is necessary to control the wheels to rotate differentially. However, the uniform rotation of the wheels is the key to providing stable suspension force. That is to say, if the wheels perform differential rotation while providing suspension force, the entire magnetic levitation vehicle may vibrate, and even affect its suspension stability and steering accuracy.

[0064] In the magnetic levitation vehicle chassis provided in the embodiment of the present application, a stable suspension force can be provided by the first wheel hub 2 and the second wheel hub 3. When steering is required, precise steering can be achieved by controlling the differential rotation of the outer first support member 4 and the second support member 5. At the same time, steering will not affect the suspension stability of the magnetic levitation vehicle.

[0065] Optionally, when the magnetic levitation vehicle is suspended, the first support member 4 and the second support member 5 can provide a stable suspension force to control the first hub 2 and the second hub 3 to perform differential rotation to achieve steering. Those skilled in the art can select and adjust according to actual needs.

[0066] In some embodiments of the present application, Figure 3 As shown, the first support member 4 may include a third stator portion 41 and a third rotor portion 42 which are sleeved on the front axle 11, the third stator portion 41 is fixedly connected to the front axle 11, and the third rotor portion 42 is located on the inner side of the third stator portion 41 and can rotate relative to the third stator portion 41; and / or, the second support member 5 includes a fourth stator portion 51 and a fourth rotor portion 52 which are sleeved on the front axle 11, the fourth stator portion 51 is fixedly connected to the rear axle 12, and the fourth rotor portion 52 is located on the inner side of the fourth stator portion 51 and can rotate relative to the fourth stator portion 51.

[0067] In the magnetic levitation vehicle chassis provided in the embodiment of the present application, the first support member 4 includes a third stator portion 41 and a third rotor portion 42. When a levitation command is received, current is passed through the winding on the third stator portion 41, and the third stator portion 41 generates a magnetic field, interacts with the third rotor portion 42, and drives the third rotor portion 42 to rotate. At this time, the third rotor portion 42 rotates relative to the third stator portion 41 and generates a time-varying magnetic field. The time-varying magnetic field interacts with the magnetic field generated at the induction plate, thereby realizing the levitation and movement of the vehicle; the principle of the fourth stator portion 51 is the same as that of the third stator portion 41, and will not be elaborated here.

[0068] Optionally, the third rotor portion 42 may include a third rotor disk and a plurality of third magnets, which are attached to the outer peripheral wall of the third rotor disk, and the third hub further includes a third rolling bearing, which is connected between the third rotor disk and the third stator portion 41; and / or, the fourth rotor portion 52 includes a fourth rotor disk and a plurality of fourth magnets, which are attached to the outer peripheral wall of the fourth rotor disk, and the third hub further includes a fourth rolling bearing, which is connected between the fourth rotor disk and the fourth stator portion 51.

[0069] In some embodiments of the present application, Figure 1 As shown, the vehicle frame 1 may further include a main frame 13, two first connecting members 14 and two second connecting members 15; the first ends of the two first connecting members 14 are rotatably connected to the main frame 13, and the second ends of the two first connecting members 14 are respectively connected to the two ends of the front axle 11 along the axial direction; the first ends of the two second connecting members 15 are respectively rotatably connected to the main frame 13, and the second ends of the two second connecting members 15 are respectively connected to the two ends of the rear axle 12 along the axial direction.

[0070] In the magnetic levitation vehicle chassis provided in the embodiment of the present application, the front axle 11 is rotatably connected to the main frame 13 through two first connecting members 14, and the rear axle 12 is rotatably connected to the main frame 13 through two second connecting members 15. This can achieve a certain degree of buffering after the magnetic levitation vehicle chassis lands, thereby avoiding excessive stress at the connection between the first support member 4 and the second support member 5 and the main frame 13, which may lead to breakage.

[0071] Optionally, the first connecting member 14 is connected to the main frame 13 via a ball hinge mechanism; and / or the second connecting member 15 is connected to the main frame 13 via a ball hinge mechanism.

[0072] In order to further improve the shock absorption capability, in some embodiments of the present application, such as Figure 1As shown, the frame 1 can also include two third connecting members 16, and a third connecting member 16 is correspondingly arranged above each first connecting member 14, one end of the third connecting member 16 is connected to the main frame 13, and the other end is an open end, and a first gap is formed between the open end and the corresponding first connecting member 14; the frame 1 also includes two fourth connecting members 17, and a fourth connecting member 17 is correspondingly arranged above each second connecting member 15, one end of the fourth connecting member 17 is connected to the main frame 13, and the other end is an open end, and a second gap is formed between the open end and the corresponding second connecting member 15; a first elastic shock absorber 18 is arranged in each first gap, and the first elastic shock absorber 18 is respectively connected to the third connecting member 16 and the corresponding first connecting member 14; a second elastic shock absorber 19 is arranged in each second gap, and the second elastic shock absorber 19 is respectively connected to the fourth connecting member 17 and the corresponding second connecting member 15. By providing the first elastic shock absorber 18 and the second elastic shock absorber 19, when the magnetic levitation vehicle lands, the connection end of the first connecting member 14 and the main frame 13 will move downward under the action of the downforce, and the end of the first connecting member 14 close to the front axle 11 will move upward, and at this time, the first elastic shock absorber 18 will be squeezed. Under the action of the elastic restoring force of the first elastic shock absorber 18, the entire chassis will produce a similar bouncing situation. After squeezing the first elastic shock absorber 18 multiple times, part of the downforce can be offset, thereby achieving a shock absorption effect; the principle of the second elastic shock absorber 19 is the same as that of the first elastic shock absorber 18, and will not be elaborated here.

[0073] Optionally, the first elastic shock absorbing member 18 may be a spring; and / or the second elastic shock absorbing member 19 may be a spring.

[0074] The present application also provides a magnetic levitation vehicle, which includes the above-mentioned magnetic levitation vehicle chassis.

[0075] In the magnetic levitation vehicle provided in the embodiment of the present application, due to the adoption of the above-mentioned magnetic levitation vehicle chassis, compared with the related art, it is necessary to first lift the entire vehicle through a lifting mechanism and then control the rotation of the wheels to obtain the suspension force. In the present application, a first support member 4 is provided on the outside of the first hub 2, and the radial dimension of the first support member 4 is larger than that of the first hub 2. A second support member 5 is provided on the outside of the second hub 3, and the radial dimension of the second support member 5 is larger than that of the first hub 2. That is, in the initial state, due to the provision of the first support member 4 and the second support member 5, the first hub 2 and the second hub 3 are already in a suspended state, and can directly rotate after obtaining the suspension command of the host, without waiting for the entire vehicle body to be suspended before rotating, and the starting speed will be faster.

[0076] In some embodiments, as Figure 4As shown, the magnetic levitation vehicle may further include a control member 6, which is connected to the first hub 2 and the second hub 3 respectively, and controls the first hub 2 and the second hub 3 to rotate in opposite directions respectively when receiving a levitation instruction.

[0077] It should be noted that after the magnetic levitation vehicle is started, the first wheel hub 2 and the second wheel hub 3 rotate synchronously in opposite directions, so a backward oblique force F1 can be formed at the first wheel hub 2, and a forward oblique force F2 can be formed at the second wheel hub 3. Under the combined force of F1 and F2, the magnetic levitation vehicle is suspended.

[0078] Optionally, the control component 6 can control the rotational speed of the first hub 2 to be lower than the rotational speed of the second hub 3, so that F1 is less than F2, and the magnetic levitation vehicle can achieve the purpose of forward movement under the action of F2. When braking is required, the rotational speeds of the first hub 2 and the second hub 3 are adjusted so that the rotational speed of the first hub 2 is greater than the rotational speed of the second hub 3, so that F1 is greater than F2, and the magnetic levitation vehicle can achieve the purpose of braking under the action of F1.

[0079] Optionally, the first support member 4 is rotatably connected to the front axle 11, and the second support member 5 is rotatably connected to the rear axle 12, and both the first support member 4 and the second support member 5 can generate a magnetic field when rotating; the control member 6 is also connected to the first support member 4 and the second support member 5 respectively, and after the magnetic levitation vehicle is suspended, when receiving a steering instruction, controls the two first support members 4 to rotate differentially; and / or controls the two second support members 5 to rotate differentially.

[0080] When steering is required, the first hub 2 and the second hub 3 can provide a stable suspension force, and the outer first support member 4 and the second support member 5 can be controlled to perform differential rotation to achieve precise steering, while achieving steering without affecting the suspension stability of the magnetic levitation vehicle.

[0081] For example, when turning left, the rotation speed of the first support member 4 on the left side is controlled to be greater than the rotation speed of the first support member 4 on the right side, and / or the rotation speed of the second support member 5 on the left side is controlled to be greater than the rotation speed of the second support member 5 on the right side. The same applies to turning right, which will not be described in detail here.

[0082] In summary, the maglev vehicle provided in the embodiments of the present application achieves stable levitation through the magnetic field generated by the first and second hubs 2 and 3 and the induction plate below the vehicle, resulting in a rapid start-up speed. During levitation, the maglev vehicle can be steered by differential rotation of the outer first and second support members 4 and 5, thereby achieving both levitation and mid-air steering. Furthermore, the maglev vehicle is driven by electromagnetic force and produces no exhaust emissions, thus reducing environmental pollution.
