[0001] This application relates to the technical field of rail transit, and particularly relates to a suspended maglev vehicle and its suspension frame. Background Art

[0002] In recent years, with the rapid development of urban transportation, medium and low-speed small-capacity maglev transportation systems have gradually become a research hotspot. Among them, the suspended maglev transportation system has broad application prospects due to its unique suspension design and small floor area. The suspended maglev vehicle realizes non-contact suspension with the track beam through suspension electromagnets and relies on linear motors to provide power, having advantages such as smooth operation and low noise. However, the running gear structure of the suspended maglev vehicle is complex, and multiple subsystems such as suspension electromagnets, guiding electromagnets, brake calipers, and linear motors need to be integrated in a limited space, which poses high requirements for the design of the frame.

[0003] Similar to traditional wheel-rail suspended monorail trains, the running gear of electromagnetic levitation suspended monorails needs to be integrally installed inside the track box girder. However, since the running wheel system of the running gear of traditional wheel-rail suspended monorail trains can singly and centrally achieve functions of support, running, and braking, its main frame structure is relatively simple. However, in the existing design of suspended maglev vehicles, the frame structure of the running gear faces double restrictions of space and weight. Due to the need to integrate multiple functional components in a limited space, traditional frame designs often have difficulty achieving lightweight while ensuring the bearing capacity. In addition, the connection and layout of each subsystem are also relatively complex, resulting in the frame structure design not being compact enough, occupying a large space, and affecting the overall performance and operation efficiency of the vehicle. Summary of the Utility Model

[0004] The purpose of this application is to provide a suspension frame for a suspended maglev vehicle. By adopting a suspension frame with a "day" - shaped structure design, it effectively realizes the reasonable integration of multiple components of the electromagnetic levitation running gear in a limited space, while ensuring the bearing capacity and stability of the frame, solving the problems of the frame structure in the prior art being not compact enough and occupying a large space, and improving the overall performance and operation efficiency of the vehicle. Another purpose of this application is to provide a suspended maglev vehicle.

[0005] To achieve the above purpose, this application provides a suspension frame for a suspended maglev vehicle, including a first longitudinal beam and a second longitudinal beam. The second longitudinal beam is located below the first longitudinal beam. The two ends of the first longitudinal beam are connected to the two ends of the second longitudinal beam, and the middle of the first longitudinal beam is connected to the middle of the second longitudinal beam. The first longitudinal beam and the second longitudinal beam as a whole are in the shape of a "day". The first longitudinal beam and the second longitudinal beam are provided with installation structures for connecting components of the electromagnetic levitation running gear.

[0006] In some embodiments, the mounting structure includes a levitation electromagnet mounting base, a traction rod mounting base, a guide electromagnet mounting base, a brake caliper mounting base, and a secondary suspension mounting base, as well as a skid mounting interface and a rescue wheel mounting interface.

[0007] In some embodiments, the levitation electromagnet mounting base is disposed on the first longitudinal beam, the levitation electromagnet mounting base is distributed on both sides of the first longitudinal beam, and the levitation electromagnet mounting base is spaced apart along the length direction of the first longitudinal beam.

[0008] In some embodiments, the suspension frame of the suspended maglev vehicle further includes a reinforcing rib, which is disposed on the first longitudinal beam and located on one side of the suspension electromagnet mounting base.

[0009] In some embodiments, the traction rod mounting base is disposed on the second longitudinal beam, the traction rod mounting base is distributed on the upper side of the second longitudinal beam, and the traction rod mounting base is spaced apart along the length direction of the second longitudinal beam.

[0011] In some embodiments, the skid mounting interface is provided on the second longitudinal beam, the skid mounting interfaces are distributed on both sides of the second longitudinal beam, the skid mounting interfaces are spaced apart along the length direction of the second longitudinal beam, and the skid mounting interfaces are located between adjacent guide electromagnet mounting seats.

[0012] In some embodiments, the rescue wheel mounting interface is provided on the second longitudinal beam, and the rescue wheel mounting interface is distributed on the lower sides of both ends of the second longitudinal beam.

[0013] In some embodiments, the brake caliper mounting base and the secondary suspension mounting base are disposed on the second longitudinal beam, the brake caliper mounting base and the secondary suspension mounting base are distributed on the lower side of the middle part of the second longitudinal beam, and the secondary suspension mounting base is located on the lower side of the brake caliper mounting base.

[0014] This application also provides a suspended maglev vehicle, including the aforementioned suspended maglev vehicle suspension frame.

[0015] Compared with the above background art, the suspension frame of the suspended maglev vehicle provided by the present application mainly includes a first longitudinal beam and a second longitudinal beam. The second longitudinal beam is located below the first longitudinal beam. The two ends of the first longitudinal beam are connected to the two ends of the second longitudinal beam, and the middle of the first longitudinal beam is connected to the middle of the second longitudinal beam. The first longitudinal beam and the second longitudinal beam are integrally in the shape of a "day". The first longitudinal beam and the second longitudinal beam are provided with mounting structures for connecting components of the electromagnetic suspension running part.

[0016] In the design of a suspended maglev vehicle, the frame structure of the running part needs to integrate multiple key components, such as suspension electromagnets, guiding electromagnets, brake calipers, etc., in a limited space to achieve functions such as vehicle suspension, guidance, and braking. Traditional frame designs often have difficulty achieving lightweight and compactness while ensuring the bearing capacity, resulting in a less compact frame structure, larger space occupation, and thus affecting the overall performance and operation efficiency of the vehicle. To solve this problem, the present application provides an innovative design for the suspension frame of a suspended maglev vehicle.

[0017] Through the adoption of a "day" - shaped structure, the frame design cleverly arranges the first longitudinal beam and the second longitudinal beam. The second longitudinal beam is located below the first longitudinal beam. The two ends of the first longitudinal beam are connected to the two ends of the second longitudinal beam, and the middle of the first longitudinal beam is connected to the middle of the second longitudinal beam, forming a stable frame structure. This "day" - shaped structure not only improves the overall stiffness and bearing capacity of the frame, but also makes the frame structure more compact, effectively reducing space occupation. In addition, multiple mounting structures are provided on the first longitudinal beam and the second longitudinal beam, which provide precise connection points and support points for each component of the electromagnetic suspension running part. By reasonably arranging and integrating these components, the frame can achieve the integration of multiple functions in a limited space, ensuring the normal operation of key functions such as vehicle suspension, guidance, and braking.

[0018] Combined with the above structural and process descriptions, it can be seen that the suspension frame of the suspended maglev vehicle has at least the following beneficial effects: By adopting a suspension frame with a "day" - shaped structure design, the suspension frame of the suspended maglev vehicle effectively realizes the reasonable integration of multiple components of the electromagnetic suspension running part in a limited space, while ensuring the bearing capacity and stability of the frame, solving the problems of the existing frame structure being less compact and occupying a larger space, and improving the overall performance and operation efficiency of the vehicle.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the suspension structure of a suspended maglev vehicle provided in an embodiment of this application.

[0030] In the first specific embodiment, the suspension frame 100 of the suspended maglev vehicle provided by the implementation scheme of the present application mainly includes a first longitudinal beam 1 and a second longitudinal beam 2. The second longitudinal beam 2 is located below the first longitudinal beam 1. The two ends of the first longitudinal beam 1 are connected to the two ends of the second longitudinal beam 2, and the middle of the first longitudinal beam 1 is connected to the middle of the second longitudinal beam 2. The first longitudinal beam 1 and the second longitudinal beam 2 are integrally in the shape of a Chinese character 'Ri' (日). The first longitudinal beam 1 and the second longitudinal beam 2 are provided with installation structures for connecting the components of the electromagnetic suspension running part.

[0031] In the design of a suspended maglev vehicle, the frame structure of the running part needs to integrate multiple key components, such as suspension electromagnets, guiding electromagnets, brake calipers, etc., within a limited space to achieve functions such as vehicle suspension, guidance, and braking. Traditional frame designs often have difficulty achieving lightweight and compactness while ensuring the bearing capacity, resulting in a less compact frame structure, larger space occupation, and thus affecting the overall performance and operation efficiency of the vehicle. To solve this problem, the present application provides an innovative design for the suspension frame of a suspended maglev vehicle.

[0032] [[ID=【6】]]This frame design cleverly arranges the first longitudinal beam 1 and the second longitudinal beam 2 by adopting a 'Ri' (日) - shaped structure. The second longitudinal beam 2 is located below the first longitudinal beam 1. The two ends of the first longitudinal beam 1 are connected to the two ends of the second longitudinal beam 2, and the middle of the first longitudinal beam 1 is connected to the middle of the second longitudinal beam 2, forming a stable frame structure. This 'Ri' - shaped structure not only improves the overall stiffness and bearing capacity of the frame, but also makes the frame structure more compact, effectively reducing space occupation. In addition, multiple installation structures are provided on the first longitudinal beam 1 and the second longitudinal beam 2, which provide precise connection points and support points for each component of the electromagnetic suspension running part. By reasonably arranging and integrating these components, the frame can integrate multiple functions within a limited space, ensuring the normal operation of key functions such as vehicle suspension, guidance, and braking.

[0033] Combined with the above - described structure and process description, it can be seen that the suspension frame 100 of the suspended maglev vehicle has at least the following beneficial effects: The suspension frame 100 of the suspended maglev vehicle effectively integrates multiple components of the electromagnetic suspension running part within a limited space by adopting a suspension frame with a 'Ri' - shaped structure design, while ensuring the bearing capacity and stability of the frame, solving the problems of insufficient compactness and large space occupation in the prior art, and improving the overall performance and operation efficiency of the vehicle.

[0034] Please refer to Figure 2 and Figure 3 , Figure 2 which is a schematic diagram of the connection between the suspension frame of the suspended maglev vehicle provided by the embodiment of the present application and the components of the electromagnetic suspension running part. Figure 3 is Figure 2A schematic diagram showing the electromagnets and linear motors hidden in the suspension frame of a suspended maglev vehicle.

[0035] In some embodiments, the mounting structure includes a levitation electromagnet mounting base 3, a traction rod mounting base 4, a guide electromagnet mounting base 5, a brake caliper mounting base 6, and a secondary suspension mounting base 7, as well as a skid mounting interface 8 and a rescue wheel mounting interface 9.

[0036] In this embodiment, the mounting structure of the suspended maglev vehicle suspension frame 100 consists of several key components to achieve precise installation and fixation of each part of the electromagnetic levitation running gear. First, the suspension electromagnet mounting base 3 is used to fix the suspension electromagnet 01, ensuring that it can stably generate electromagnetic force during operation to achieve the vehicle's levitation function. This mounting base design allows the suspension electromagnet 01 to be firmly installed on the first longitudinal beam 1, thereby effectively transmitting electromagnetic force to the frame.

[0037] The traction rod mounting bracket 4 connects to the traction rod 02, transmitting the traction force generated by the linear motor 08 to the vehicle body, thereby driving the vehicle forward. This design ensures effective transmission of traction force, improving the vehicle's operating efficiency and stability. The guide electromagnet mounting bracket 5 secures the guide electromagnet 03, enabling it to effectively generate lateral guiding force, ensuring stable vehicle operation on the track and preventing deviation from the track. This mounting bracket design allows the guide electromagnet 03 to be firmly installed on the second longitudinal beam 2, ensuring its stability during operation.

[0038] Brake caliper mounting bracket 6 is used to mount brake calipers 04. When braking is required, brake calipers 04 can quickly clamp onto the track beam, generating braking force to slow down or stop the vehicle. This design improves the vehicle's braking performance and ensures operational safety. Secondary suspension mounting bracket 7 is used to connect the secondary suspension 05, transmitting vehicle vibrations and impacts to the frame, acting as a shock absorber and buffer, improving ride comfort. This mounting bracket design allows the secondary suspension 05 to be effectively connected to the frame, improving vehicle comfort and stability.

[0039] Furthermore, the skid mounting interface 8 is used to connect the skid 06. When the levitation electromagnet 01 fails or malfunctions, the skid 06 provides necessary support and sliding function to ensure the vehicle does not fall. The rescue wheel mounting interface 9 is used to install the rescue wheel 07. In emergencies, the rescue wheel 07 can be activated to further provide support and guidance, ensuring vehicle safety. Through these carefully designed mounting structures, the suspended maglev vehicle suspension frame 100 effectively integrates and secures the various components of the electromagnetic levitation running gear, ensuring stable and efficient vehicle operation under various working conditions.

[0040] In some embodiments, the levitation electromagnet mounting base 3 is disposed on the first longitudinal beam 1, and the levitation electromagnet mounting base 3 is distributed on both sides of the first longitudinal beam 1, and the levitation electromagnet mounting base 3 is spaced apart along the length direction of the first longitudinal beam 1.

[0041] In this embodiment, the levitation electromagnet mounting base 3 is a key component installed on the first longitudinal beam 1 of the suspension frame 100 of the suspended maglev vehicle. These mounting bases 3 are designed to be distributed on both sides of the first longitudinal beam 1 to accommodate the installation requirements of the levitation electromagnet 01. By spaced the levitation electromagnet mounting bases 3 along the length of the first longitudinal beam 1, it is ensured that the levitation electromagnet 01 is evenly distributed on the frame, thereby balancing the forces and loads generated during vehicle operation. This layout not only helps improve the vehicle's suspension stability and load-bearing capacity but also effectively disperses electromagnetic forces, reduces local stress concentration on the frame, and extends the frame's service life. Furthermore, the spaced-out levitation electromagnet mounting bases 3 also facilitate vehicle maintenance and repair, making the replacement and adjustment of the levitation electromagnet 01 easier.

[0042] In some cases, the levitation electromagnet mounting base 3 is located on both sides of the first longitudinal beam 1, with four on each side of the frame 100, for a total of eight. Each mounting base 3 is connected to the bracket of the levitation electromagnet 01 by four sets of bolts, so that the vertical electromagnetic tension on the levitation electromagnet 01 is transmitted to the overall frame 100 when the vehicle is levitated.

[0043] In some embodiments, the suspension frame 100 of the suspended maglev vehicle further includes a reinforcing rib 10, which is disposed on the first longitudinal beam 1 and located on one side of the suspension electromagnet mounting base 3.

[0044] In this embodiment, the suspension frame 100 of the suspended maglev vehicle further includes reinforcing ribs 10 to enhance the structural strength and stability of the frame. These reinforcing ribs 10 are disposed on the first longitudinal beam 1 and located on one side of the suspension electromagnet mounting base 3. Since the suspension electromagnet 01 generates a large electromagnetic force during operation, the reinforcing ribs 10 near the suspension electromagnet mounting base 3 can effectively disperse and bear these forces, preventing deformation or damage to the frame during long-term operation. The design of the reinforcing ribs 10 helps to improve the overall rigidity of the frame, ensuring that it maintains a stable load-bearing capacity under various working conditions, thereby providing a reliable guarantee for the safe operation of the vehicle.

[0045] In some embodiments, the traction rod mounting base 4 is disposed on the second longitudinal beam 2, and the traction rod mounting base 4 is distributed on the upper side of the second longitudinal beam 2, and the traction rod mounting base 4 is spaced apart along the length direction of the second longitudinal beam 2.

[0046] In this embodiment, the traction rod mounting seats 4 are mounted on the second longitudinal beam 2 of the suspension frame 100 of the suspended maglev vehicle. These mounting seats 4 are located on the upper side of the second longitudinal beam 2 to connect with the traction rods 02. The traction rod mounting seats 4 are spaced apart along the length of the second longitudinal beam 2. This layout allows the traction rods 02 to be evenly distributed on the frame, thereby effectively transmitting the traction force generated by the linear motor 08 to the vehicle body. By spaced out the traction rod mounting seats 4, the balanced transmission of traction force can be ensured, avoiding overload of the frame or related components due to force concentration, thereby improving the vehicle's operational stability and reliability. In addition, this design also facilitates the maintenance and repair of the traction system, making the inspection and replacement of the traction rods 02 easier.

[0047] In some cases, the traction rod mounting base 4 is located on the upper surface of the second longitudinal beam 2. There are two of them in each frame 100. Each mounting base 4 is connected to the bracket of the traction rod 02 by eight sets of bolts, so as to transmit the longitudinal traction force of the linear motor 08 to the main frame 100.

[0048] In some embodiments, the guide electromagnet mounting base 5 is disposed on the second longitudinal beam 2, and the guide electromagnet mounting base 5 is distributed on both sides of the second longitudinal beam 2, and the guide electromagnet mounting base 5 is spaced apart along the length direction of the second longitudinal beam 2.

[0049] In this embodiment, the guide electromagnet mounting seats 5 are disposed on the second longitudinal beam 2 of the suspension frame 100 of the suspended maglev vehicle, specifically distributed on both sides of the second longitudinal beam 2. This design allows the guide electromagnets 03 to be symmetrically installed on both sides of the frame, thereby generating a balanced lateral guiding force during vehicle operation. The guide electromagnet mounting seats 5 are spaced apart along the length of the second longitudinal beam 2, ensuring a uniform distribution of the guide electromagnets 03 over the entire running length. This spaced layout helps improve the vehicle's guiding accuracy and stability, making the vehicle run more smoothly on the track and reducing vehicle swaying or deviation caused by uneven guiding force. At the same time, the spaced guide electromagnet mounting seats 5 also facilitate vehicle maintenance and repair, making the inspection and replacement of the guide electromagnets 03 easier.

[0050] In some cases, the guide electromagnet mounting base 5 is located on both sides of the second longitudinal beam 2. There are four on each side of the frame 100, for a total of eight. Each mounting base 5 is connected to the bracket of the guide electromagnet 03 by four sets of bolts, so as to transfer the lateral guiding force on the guide electromagnet 03 to the overall frame 100.

[0051] In some embodiments, the skid mounting interface 8 is provided on the second longitudinal beam 2, the skid mounting interfaces 8 are distributed on both sides of the second longitudinal beam 2, the skid mounting interfaces 8 are spaced apart along the length direction of the second longitudinal beam 2, and the skid mounting interfaces 8 are located between adjacent guide electromagnet mounting seats 5.

[0052] In this embodiment, the skid mounting interfaces 8 are disposed on the second longitudinal beam 2 of the suspension frame 100 of the suspended maglev vehicle, specifically distributed on both sides of the second longitudinal beam 2. This arrangement allows the skids 06 to be symmetrically mounted on both sides of the frame, providing the necessary support and sliding function for the vehicle, especially when the suspension electromagnet 01 fails or is not working. The skid mounting interfaces 8 are spaced apart along the length of the second longitudinal beam 2, ensuring that the skids 06 are evenly distributed along the entire length of the running gear, thereby providing stable support and guidance during vehicle operation.

[0053] Furthermore, the skid mounting interface 8 is cleverly designed to be located between adjacent guide electromagnet mounting seats 5. This design not only allows the skid 06 and guide electromagnet 03 to cooperate spatially, but also forms a complementary relationship functionally. When the guide electromagnet 03 is working normally, the skid 06 can act as an auxiliary support, reducing the burden on the electromagnet system; and when the guide electromagnet 03 fails or requires additional support, the skid 06 can quickly take effect, ensuring the safe and stable operation of the vehicle. This design improves the reliability and safety of the vehicle, while also facilitating vehicle maintenance and repair, making the inspection and replacement of the skid 06 easier.

[0054] In some cases, the skid mounting interface 8 is located on both sides of the second longitudinal beam 2, with two on each side of the frame 100, for a total of four. Each skid mounting structure is connected to the bracket of the skid 06 by six sets of bolts. When the levitation electromagnet 01 is not working or fails, the vertical support force and longitudinal friction force of the skid 06 are transmitted to the overall frame 100.

[0055] In some embodiments, the rescue wheel mounting interface 9 is provided on the second longitudinal beam 2, and the rescue wheel mounting interface 9 is distributed on the lower sides of both ends of the second longitudinal beam 2.

[0056] In this embodiment, the rescue wheel mounting interface 9 is located on the second longitudinal beam 2 of the suspended maglev vehicle suspension frame 100, specifically distributed on the lower sides of both ends of the second longitudinal beam 2. This design allows the rescue wheels 07 to be installed at both ends of the frame, providing additional safety for the vehicle. When the vehicle encounters an emergency, such as the failure of the levitation electromagnet 01 or other malfunctions that prevent the vehicle from leviting normally, the rescue wheels 07 can be quickly activated and contact the track beam, providing necessary support and guidance to prevent the vehicle from falling or other dangerous situations.

[0057] The installation interfaces 9 for the rescue wheels are located on the lower sides of both ends of the second longitudinal beam 2, which helps to form stable support points at both ends of the vehicle, ensuring that the vehicle can quickly and smoothly switch to the support state of the rescue wheels 07 in an emergency. This layout also helps to distribute the force generated by the rescue wheels 07 during operation, avoiding excessive impact on the frame or other vehicle components. In addition, this design facilitates the maintenance and repair of the rescue wheels 07, allowing for quick inspection and replacement when needed, ensuring that they are always in good working order and providing reliable protection for the safe operation of the vehicle.

[0058] In some cases, the rescue wheel mounting interface 9 is located on the lower side of both ends of the second longitudinal beam 2, with a total of eight sets. Each set of structures is connected to the rescue wheel 07 system by six sets of bolts, which transmits vertical force to the frame 100 when the rescue wheel 07 is activated.

[0059] In some embodiments, the brake caliper mounting seat 6 and the secondary suspension mounting seat 7 are disposed on the second longitudinal beam 2, and the brake caliper mounting seat 6 and the secondary suspension mounting seat 7 are distributed on the lower side of the middle part of the second longitudinal beam 2, with the secondary suspension mounting seat 7 located below the brake caliper mounting seat 6.

[0060] In this embodiment, both the brake caliper mounting seat 6 and the secondary suspension mounting seat 7 are mounted on the second longitudinal beam 2 of the suspension frame 100 of the suspended maglev vehicle. Specifically, both mounting seats are located on the lower middle part of the second longitudinal beam 2, with the brake caliper mounting seat 6 used to fix the brake caliper 04, and the secondary suspension mounting seat 7 used to connect the secondary suspension 05. This arrangement allows the braking system and suspension system to be effectively integrated and work together in key parts of the vehicle.

[0061] The brake caliper mount 6 is located on top, ensuring that the brake caliper 04 can respond quickly and clamp onto the rail beam to generate braking force, slowing or stopping the vehicle. This design helps improve the vehicle's braking performance and safety. The secondary suspension mount 7 is located below the brake caliper mount 6, allowing the secondary suspension 05 to effectively absorb and mitigate vibrations and shocks generated during vehicle operation, improving ride comfort and vehicle stability. By integrating these two key systems into the lower middle part of the second longitudinal beam 2, not only is the spatial layout optimized, but the overall performance and reliability of the vehicle are also enhanced.

[0062] In some cases, the brake caliper mounting base 6 is located on both sides of the frame 100 and is welded to the frame 100. The brake caliper 04 is mounted on the mounting base 6 at both ends by four sets of bolts. When the brake caliper 04 is activated, the longitudinal braking force of the caliper is transmitted to the overall frame 100.

[0063] In some cases, the secondary suspension mounting seat 7 is located at the lower end of the entire frame 100, connecting the secondary suspension 05 structure of the suspension frame, and transmitting the forces and loads of the entire running gear to the vehicle body suspended below through the secondary suspension 05.

[0064] In some embodiments, the suspension maglev vehicle suspension frame 100 adopts a steel plate welded structure, including the first longitudinal beam 1 and the second longitudinal beam 2, which are welded by low-carbon high-alloy plates, and adopts a lightweight design to minimize the weight while ensuring the bearing capacity.

[0065] This application also provides a suspension maglev vehicle, including the above-mentioned suspension maglev vehicle suspension frame 100.

[0066] The suspension maglev vehicle should have all the beneficial technical effects of the above-mentioned suspension maglev vehicle suspension frame 100. As the support structure of the running gear suspension frame and accessories, the frame composition can effectively carry and transmit various forces and loads. Its structure, shape and size meet the assembly requirements of system components such as the suspension system, drive system, and basic braking device, ensuring that the suspension and lifting functions of the suspension frame and the requirements for line operation are met.

[0067] The running gear frame adopts a steel plate welded structure, and the main frame is in the shape of a "day". It consists of other welded accessories such as the suspension electromagnet mounting seat 3, traction rod mounting seat 4, guiding electromagnet mounting seat 5, skid mounting interface 8, rescue wheel mounting interface 9, brake caliper mounting seat 6, and secondary suspension mounting seat 7 from top to bottom. This design not only improves the bearing capacity and stability of the frame, but also achieves lightweight and compactness, enhancing the overall performance and operation efficiency of the vehicle.

[0068] It should be noted that many components mentioned in this application are common standard components or components known to those skilled in the art, and their structures and principles can be known by those skilled in the art through technical manuals or obtained through conventional experimental methods.

[0069] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
