Description

Technical Field

[0001] This invention relates to the field of modular vehicle transportation technology, specifically to a construction method for transporting 30E main section modular vehicles based on dual PPU drive. Background Technology

[0002] Modular vehicles are cars that are designed and manufactured in a standardized manner, allowing for the sharing and assembly of components between different models. Modular vehicles are characterized by flexibility, customizability, and scalability, and can meet the personalized needs of consumers and ever-changing market demands. Therefore, modular vehicles have a wide range of applications.

[0003] There are still some problems with the common 30E modular vehicle transportation and construction equipment. For example, when using modular vehicles for transportation, the modular vehicles need to be moved, which is inconvenient to drive the modular vehicles according to the needs and can easily affect the operation of the modular vehicles.

[0004] Therefore, we propose a novel construction method for transporting 30E modular sections using a dual-PPU driven vehicle to address the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a method for transporting and constructing 30E modular vehicles based on dual PPU drive, so as to solve the problem mentioned in the background art that it is inconvenient to drive the modular vehicles according to demand and that it is easy to affect the operation of the modular vehicles.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a 30E main section modular vehicle transportation and construction device based on dual PPU drive, comprising a vehicle body, a base plate fixedly connected to the front and rear ends of the bottom of the vehicle body, wheels movably connected to the front and rear ends of the bottom of the base plate, a base provided on the right side of the vehicle body, and a drive structure provided at the bottom end of the base.

[0007] The drive structure includes a sprocket, a rotating shaft, and a motor. A connecting shaft is movably connected to the left and right sides of the bottom of the base. Drive wheels are installed at the front and rear ends of the connecting shaft. Mounting plates are fixedly connected to the front and rear ends of the top of the sprocket. A motor is installed at the end of the mounting plate near the outside. A rotating shaft is fixedly connected to the output end of the motor. Sprockets are fixedly connected to the outside of the rotating shaft and the connecting shaft respectively. A drive chain is provided on the outside of the sprocket. A control box is provided at the top of the base.

[0008] As a further technical solution of the present invention, the sprockets are arranged on the left and right sides inside the drive chain, and the motor is provided in two sets.

[0009] As a further technical solution of the present invention, a power management module is provided inside the control box, and the drive wheels are located at the four corners at the bottom of the base, with multiple sets of wheels.

[0010] As a further technical solution of the present invention, a fixing plate is fixedly connected to the left side of the vehicle body and the base respectively, and a connecting block is fixedly connected to the right side of the vehicle body. Fixing holes are opened inside the connecting block and the fixing plate respectively, and fixing pins are provided inside the fixing holes.

[0011] As a further technical solution of the present invention, the bottom ends of the left and right sides of the base plate and the base are respectively fixedly connected to the second mounting block, and the bottom end of the right side of the base plate is fixedly connected to the first mounting block. Limiting holes are respectively opened inside the second mounting block and the first mounting block.

[0012] As a further technical solution of the present invention, the connecting block is embedded inside the fixing plate, and the connecting block is fixed between the fixing plates by fixing pins and fixing holes.

[0013] As a further technical solution of the present invention, a connecting plate is fixedly connected to the front and rear ends of the top of the vehicle body. A limiting groove is opened inside the connecting plate, and a slider slides inside the limiting groove. Adjustment holes are opened at the front and rear ends of the slider and the connecting plate respectively. A fixing bolt is installed inside the adjustment hole, and a support rod is fixedly connected to the top of the slider.

[0014] As a further technical solution of the present invention, a support plate is fixedly connected to the top end of the support rod.

[0015] As a further technical solution of the present invention, the slider slides left and right inside the limiting groove, and the slider is fixed inside the connecting plate by adjusting holes and fixing bolts, and the adjusting holes are provided in several sets.

[0016] A method for transporting 30E modular sections using a dual-PPU driven vehicle includes the following steps:

[0017] P1: Insert the connecting block on the right side of the vehicle body between the fixing plates on the left side of the base, and then insert the fixing pin into the fixing hole to connect the vehicle body and the base. When the connecting block is inserted between the fixing plates, the second mounting block and the limiting hole will be aligned with the limiting hole inside the first mounting block. After the limiting hole is aligned, insert the fixing pin into the fixing hole to further fix the vehicle body and the base.

[0018] P2: When the length of the vehicle body is insufficient, the connecting blocks of another set of vehicle bodies are embedded between the fixed plates on the left side of the vehicle body. The support rods and support plates can support the main module that needs to be supported.

[0019] P3: When it is necessary to adjust the distance between the support plates, unscrew the fixing bolts from the inside of the adjustment hole to make the slider unfixed. After the slider is unfixed, push the support rod. The support rod can drive the slider to slide inside the connecting plate, thereby adjusting the distance between the support plates.

[0020] P4: After adjustment, screw the fixing bolts into the adjustment hole again to limit and fix the slider. When the vehicle body needs to move the transport section module, start the motor. The motor drives the sprocket to rotate through the shaft. The sprocket drives the connecting shaft and drive wheel to rotate through the drive chain, so that the base moves. The movement of the base can move the vehicle body to transport the section module.

[0021] Compared with the prior art, the beneficial effects of the present invention are: the 30E modular vehicle transportation and construction device based on dual PPU drive not only realizes the ease of driving the vehicle body according to needs and the ease of splicing between vehicle bodies, but also makes it easy to adjust the position of the support plate.

[0022] (1) The system is equipped with a control box, drive chain, sprocket, shaft, motor and mounting plate. When the vehicle body needs to move the transport section module, the motor is started. The motor drives the sprocket to rotate through the shaft. The sprocket drives the connecting shaft and drive wheel to rotate through the drive chain, which moves the base. The movement of the base can move the vehicle body to move the transport section module. The control box is equipped with a power management module. The power management module can control the core module of the motor system. Using dual PPU drive can bring significant performance improvement, load balancing, resource utilization efficiency, cost-effectiveness, flexibility, compatibility and many other advantages such as latency hiding and synchronization optimization.

[0023] (2) By setting up connecting blocks, fixing pins, first mounting blocks, second mounting blocks, limiting holes, fixing plates, and fixing holes, when it is necessary to install the base on the right side of the vehicle body, the connecting blocks are embedded between the fixing plates on the left side of the base, and then the fixing pins are inserted into the fixing holes to connect the vehicle body and the base. When the connecting blocks are embedded between the fixing plates, the second mounting blocks and limiting holes will be aligned with the limiting holes inside the first mounting blocks. After the limiting holes are aligned, the fixing pins are inserted into the fixing holes to further fix the vehicle body and the base. When the length of the vehicle body is insufficient, the connecting blocks of another set of vehicle bodies are embedded between the fixing plates on the left side of the vehicle body.

[0024] (3) By setting up a connecting plate, a limiting slide, a support plate, a support rod, a fixing bolt, a slider and an adjustment hole, the support rod and the support plate can support the main section module that needs to be supported. When it is necessary to adjust the distance between the support plates, the fixing bolt is unscrewed from the inside of the adjustment hole to make the slider lose its fixation. After the slider loses its fixation, the support rod is pushed, and the support rod can drive the slider to slide inside the connecting plate, thereby adjusting the distance between the support plates. This makes it convenient to support different main section modules according to the needs. After adjustment, the fixing bolt is screwed into the inside of the adjustment hole again to limit and fix the slider. Attached Figure Description

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0033] Please see Figure 1-6 The present invention provides an embodiment of a 30E modular vehicle transportation and construction device based on dual PPU drive, comprising a vehicle body 1, a base plate 3 fixedly connected to the front and rear ends of the bottom of the vehicle body 1, wheels 4 movably connected to the front and rear ends of the bottom of the base plate 3, a base 7 provided on the right side of the vehicle body 1, and a drive structure provided at the bottom of the base 7.

[0034] The drive structure includes a sprocket 17, a rotating shaft 18, and a motor 19. A connecting shaft 15 is movably connected to the left and right sides of the bottom of the base 7. Drive wheels 9 are installed at the front and rear ends of the connecting shaft 15. Mounting plates 20 are fixedly connected to the front and rear ends of the top of the sprocket 17. A motor 19 is installed at the end of the mounting plate 20 near the outside. The output end of the motor 19 is fixedly connected to the rotating shaft 18. The sprocket 17 is fixedly connected to the outside of the rotating shaft 18 and the connecting shaft 15 respectively. A drive chain 16 is provided on the outside of the sprocket 17. A control box 8 is provided at the top of the base 7.

[0036] Specifically, if Figure 1 , Figure 2 and Figure 5 As shown, when the vehicle body 1 needs to move the transport module, the motor 19 is started. The motor 19 drives the sprocket 17 to rotate through the shaft 18. The sprocket 17 then drives the connecting shaft 15 and the drive wheel 9 to rotate through the drive chain 16, causing the base 7 to move. The movement of the base 7 allows the vehicle body 1 to move the transport module. A power management module is installed inside the control box 8. The power management module can control the core module of the motor 19 system. Using dual PPU drive can bring significant advantages in terms of performance improvement, load balancing, resource utilization efficiency, cost-effectiveness, flexibility, compatibility, latency hiding, and synchronization optimization.

[0037] A fixing plate 13 is fixedly connected to the left side of the vehicle body 1 and the base 7 respectively, and a connecting block 5 is fixedly connected to the right side of the vehicle body 1. The connecting block 5 and the fixing plate 13 are respectively provided with fixing holes 14. Fixing pins 6 are provided inside the fixing holes 14. The bottom ends of the left and right sides of the base plate 3 and the base 7 are respectively fixedly connected to the second mounting block 11. The bottom end of the right side of the base plate 3 is fixedly connected to the first mounting block 10. Limiting holes 12 are respectively provided inside the second mounting block 11 and the first mounting block 10. The connecting block 5 is embedded in the fixing plate 13. The connecting block 5 is fixed between the fixing plates 13 by fixing pins 6 and fixing holes 14.

[0038] Specifically, if Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the base 7 needs to be installed on the right side of the vehicle body 1, the connecting block 5 is embedded between the fixing plates 13 on the left side of the base 7, and then the fixing pin 6 is inserted into the fixing hole 14 to connect the vehicle body 1 and the base 7. When the connecting block 5 is embedded between the fixing plates 13, the second mounting block 11 and the limiting hole 12 will be aligned with the limiting hole 12 inside the first mounting block 10. After the limiting hole 12 is aligned, the fixing pin 6 is inserted into the fixing hole 14 to further fix the vehicle body 1 and the base 7. When the length of the vehicle body 1 is insufficient, another set of connecting blocks 5 of the vehicle body 1 is embedded between the fixing plates 13 on the left side of the vehicle body 1.

[0039] Connecting plates 2 are fixedly connected to the front and rear ends of the top of the vehicle body 1. A limiting groove 21 is opened inside the connecting plate 2. A slider 25 slides inside the limiting groove 21. Adjustment holes 26 are opened at the front and rear ends of the slider 25 and the connecting plate 2 respectively. Fixing bolts 24 are installed inside the adjustment holes 26. A support rod 23 is fixedly connected to the top of the slider 25. A support plate 22 is fixedly connected to the top of the support rod 23. The slider 25 slides left and right inside the limiting groove 21. The slider 25 is fixed inside the connecting plate 2 through the adjustment holes 26 and the fixing bolts 24. Several sets of adjustment holes 26 are provided.

[0040] Specifically, if Figure 1 , Figure 3 and Figure 6 As shown, the support rod 23 and the support plate 22 can support the main module that needs to be supported. When it is necessary to adjust the distance between the support plates 22, the fixing bolt 24 is unscrewed from the inside of the adjustment hole 26 to make the slider 25 unfixed. After the slider 25 is unfixed, it pushes the support rod 23. The support rod 23 can drive the slider 25 to slide inside the connecting plate 2, thereby adjusting the distance between the support plates 22. This makes it convenient to support different main modules according to the needs. After adjustment, the fixing bolt 24 is screwed into the inside of the adjustment hole 26 again to limit and fix the slider 25.

[0041] A method for transporting 30E modular sections using a dual-PPU driven vehicle includes the following steps:

[0042] P1: Insert the connecting block 5 on the right side of the vehicle body 1 between the fixing plate 13 on the left side of the base 7, and then insert the fixing pin 6 into the fixing hole 14 to connect the vehicle body 1 and the base 7. When the connecting block 5 is inserted between the fixing plates 13, the second mounting block 11 and the limiting hole 12 will be aligned with the limiting hole 12 inside the first mounting block 10. After the limiting hole 12 is aligned, insert the fixing pin 6 into the fixing hole 14 to further fix the vehicle body 1 and the base 7.

[0043] P2: When the length of the vehicle body 1 is insufficient, the connecting block 5 of another set of vehicle body 1 is embedded between the fixing plate 13 on the left side of the vehicle body 1, and the support rod 23 and the support plate 22 can support the main section module that needs to be supported.

[0044] P3: When it is necessary to adjust the distance between the support plates 22, unscrew the fixing bolt 24 from the inside of the adjustment hole 26 to make the slider 25 unfixed. After the slider 25 is unfixed, push the support rod 23. The support rod 23 can drive the slider 25 to slide inside the connecting plate 2, thereby adjusting the distance between the support plates 22.

[0045] P4: After adjustment, screw the fixing bolt 24 into the adjustment hole 26 again to limit and fix the slider 25. When the vehicle body 1 needs to move the transport section module, start the motor 19. The motor 19 drives the sprocket 17 to rotate through the rotating shaft 18. The sprocket 17 drives the connecting shaft 15 and the drive wheel 9 to rotate through the drive chain 16, so that the base 7 can move. The movement of the base 7 can make the vehicle body 1 move the transport section module.

[0046] Working principle: In use, the connecting block 5 on the right side of the vehicle body 1 is embedded between the fixing plates 13 on the left side of the base 7. Then, the fixing pin 6 is inserted into the fixing hole 14 to connect the vehicle body 1 and the base 7. When the connecting block 5 is embedded between the fixing plates 13, the second mounting block 11 and the limiting hole 12 will align with the limiting hole 12 inside the first mounting block 10. After the limiting hole 12 is aligned, the fixing pin 6 is inserted into the fixing hole 14 to further fix the vehicle body 1 and the base 7. When the length of the vehicle body 1 is insufficient, another set of connecting blocks 5 of the vehicle body 1 is embedded between the fixing plates 13 on the left side of the vehicle body 1. The support rod 23 and the support plate 22 can support the main module that needs to be supported. When it is necessary to adjust the distance between the support plates 22, the fixing bolt 24 is unscrewed from the inside of the adjustment hole 26 to make the slider 25 lose its fixation. After the slider 25 loses its fixation, it pushes the support rod 23. The slider 25 slides inside the connecting plate 2, thereby adjusting the distance between the support plates 22 to facilitate support for different main modules as needed. After adjustment, the fixing bolt 24 is screwed into the adjusting hole 26 to limit and fix the slider 25. When the vehicle body 1 needs to move to transport the main module, the motor 19 is started. The motor 19 drives the sprocket 17 to rotate through the rotating shaft 18. The sprocket 17 then drives the connecting shaft 15 and the drive wheel 9 to rotate through the drive chain 16, causing the base 7 to move. The movement of the base 7 allows the vehicle body 1 to move to transport the main module. A power management module is installed inside the control box 8. The power management module can control the core module of the motor 19 system. Using dual PPU drive can bring significant performance improvement, load balancing, resource utilization efficiency, cost-effectiveness, flexibility, compatibility, latency hiding, and synchronization optimization, among other advantages.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
