[0002] Currently, with the development of China's motor vehicle industry, an increasing number of automobiles and new energy vehicles are being shipped from their production sites to various parts of the world to promote economic development. However, the current transportation methods using ordinary specialized vehicles and ships are gradually failing to meet the requirements of logistics cost control and personalized customer service. Therefore, containerized vehicle transportation, which integrates sea, land, and rail transport, is becoming increasingly common.

[0003] When transporting vehicles in containers, in order to make full use of the space inside the container, vehicle transport racks are usually set up inside the container to load vehicles, thereby increasing the number of vehicles that can be loaded into a single container.

[0004] However, the existing vehicle transport racks are fixed inside the containers, which makes it inconvenient to use the containers and reduces their utilization efficiency. Summary of the Invention

It should be understood that this application can have various variations in different embodiments, all of which do not depart from the scope of this application, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this application.

[0052] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0053] In related technologies, a shipping container (not shown in the figure) includes a floor, two side walls, two end walls, and a roof. Multiple vehicles are housed within the container. The road surface outside the container serves as the working ground, and vehicles can be moved from the working ground into the container via a modular chassis.

[0054] Containers facilitate multimodal transport of vehicles, including sea, land, and rail. They also allow for easy stacking and transshipment of vehicles, effectively improving transport efficiency and ensuring vehicle safety during transit.

[0055] Multiple containers can be stacked to further improve vehicle transportation efficiency and reduce vehicle transportation costs.

[0056] For ease of understanding and description, the vehicle's stationary state will be used as a reference, the vehicle's height direction will be referred to as the vertical direction below, the vehicle's length direction will be referred to as the longitudinal direction below, and the vehicle's width direction will be referred to as the transverse direction below.

[0057] Figure 1 This is a schematic diagram of the modular vehicle transport frame of the present invention inside a container. Figure 2 This is a structural diagram of the modular vehicle transport frame of the present invention before use. Figure 3 yes Figure 2 The diagram shows a structural schematic from another perspective.

[0058] See Figures 1 to 3 This application provides a modular vehicle transport frame for positioning and transporting vehicles into containers. The modular vehicle transport frame includes: a fixed support frame 200, a height adjustment assembly 300, and a vehicle transport frame 400. The fixed support frame 200 is used for positioning and connecting with the container. The fixed support frame 200 includes at least two first support tubes 210 and a first connecting structure 220, with the first support tubes 210 spaced apart. The first connecting structure 220 connects two of the first support tubes 210 respectively. The height adjustment assembly 300 includes a first height adjustment frame 360 ​​and a second height adjustment frame 370. The first height adjustment frame 360 ​​and the second height adjustment frame 370 are respectively disposed at both ends of the first support tube 210. The first height adjustment frame 360 ​​and the second height adjustment frame 370 are movably mounted on the first support tube 210, and the lower ends of the first height adjustment frame 360 ​​and the second height adjustment frame 370 can be detachably connected to the first support tube 210. The vehicle transport frame 400 is used to carry and limit the vehicle. The two ends of the vehicle transport frame 400 are detachably connected to the first height adjustment frame 360 ​​and the second height adjustment frame 370, respectively, so that the height of the two ends of the vehicle transport frame 400 can be adjusted respectively.

[0059] When the modular vehicle transport frame is used to carry and transport vehicles, the first height adjustment frame 360 ​​and the second height adjustment frame 370 can move on the first support tube 210 to adapt to different types of vehicles. The vehicle transport frame 400 is detachably connected to the first height adjustment frame 360 ​​and the second height adjustment frame 370 to carry and restrain vehicles. The fixed support frame 200 can be moved into the container and restrained within the container to facilitate the stacking of vehicles inside the container.

[0060] The vehicle transport frame 400 can be limited by the first height adjustment frame 360 ​​and the second height adjustment frame 370 respectively, thereby adjusting the height of both ends of the vehicle transport frame 400 to adapt to different types of vehicles, improve vehicle transport efficiency, and reduce transport costs.

[0061] During the movement of the first height adjustment frame 360, the second height adjustment frame 370, and the vehicle transport frame 400, the vehicle's center of gravity can be adjusted so that it is located in the middle of the fixed support frame 200. This facilitates the fixed support frame 200 in evenly transferring the vehicle's weight to the container floor, thereby ensuring the reliability and stability of the container and the modular transport frame.

[0062] Once the container arrives at its destination, the vehicles are unloaded from the modular transport frame. The modular transport frame is then disassembled so that the fixed support frame 200, height adjustment assembly 300, and vehicle transport frame 400 can be stacked and transported separately, thereby reducing the idle cost of the transport equipment and improving logistics efficiency.

Figure 5 This is a schematic diagram of the structure of the vehicle after it has entered the modular transport frame according to the present invention. Figure 6 This is a schematic diagram of the modular vehicle transport frame of the present invention when lifting a vehicle. Figure 7 yes Figure 6 The diagram shows a structural schematic from another perspective.

Figure 9 This is a schematic diagram of the modular vehicle transport frame of the present invention after the vehicle transport frame has been disassembled. Figure 10 This is a structural schematic diagram of the fixed support frame of the present invention.

[0064] See Figures 1 to 10 In this embodiment, the modular vehicle transport frame may include a fixed support frame 200. A height adjustment assembly 300 and a vehicle transport frame 400 are connected to the fixed support frame 200. The fixed support frame 200 can contact and limit the movement of the container floor, thereby evenly transferring the weight of the vehicle and the modular transport frame to the container floor.

[0065] Figure 11 yes Figure 10 The structure shown is illustrated from another perspective. Figure 12 yes Figure 11 Enlarged view of the structure at point B.

[0066] See Figures 6 to 12 The fixed support frame 200 includes at least two first support tubes 210 and a first connecting structure 220, with the first support tubes 210 arranged at intervals. The two ends of each first support tube 210 are detachably connected to a first height adjusting frame 360 ​​and a second height adjusting frame 370, respectively. The first connecting structure 220 connects to both first support tubes 210 to secure and limit their position.

[0067] The first support tube 210 extends longitudinally. At least two first support tubes 210 are arranged laterally at intervals. The first support tubes 210 can abut against the container floor so as to evenly transfer the weight they bear to the container floor.

[0068] The first support tube 210 has a square tube structure. One side wall of the first support tube 210 can be attached to and supported against the floor of the container. The square tube structure of the first support tube 210 facilitates connection with the height adjustment component 300, thereby improving the structural strength between the first support tube 210 and the height adjustment component 300 and ensuring the load-bearing capacity of the modular transport frame.

[0069] In some embodiments, the fixed support frame 200 includes two first support tubes 210, and a first height adjustment frame 360 ​​and a second height adjustment frame 370 are respectively provided at both ends of the first support tubes 210. The height and tilt angle of the vehicle transport frame 400 can be adjusted by the two first height adjustment frames 360 and the two second height adjustment frames 370 respectively.

[0070] See Figures 6 to 12 In this embodiment, the distance between the two first support tubes 210 in the lateral direction is greater than the width of the vehicle transport frame 400, so as to facilitate the vertical movement of the vehicle transport frame 400 on the fixed support frame 200. Furthermore, after the fixed support frame 200 is positioned relative to the container floor, another vehicle transport frame 400 can extend between the two first support tubes 210 to facilitate the stacking of vehicles, thereby improving the space utilization of the container and reducing the transportation cost of the vehicles.

[0071] See Figures 6 to 12In this embodiment, one end of the fixed support frame 200 and / or the vehicle transport frame 400 is provided with a roller 225 for sliding on the floor of the container; the other end of the fixed support frame 200 and / or the vehicle transport frame 400 is provided with a hook structure 224 for connecting with a forklift so as to lift the end of the fixed support frame 200 and / or the vehicle transport frame 400.

[0072] One end of the fixed support frame 200 is provided with a roller 225 for sliding on the floor of the container. The other end of the fixed support frame 200 is provided with a hook structure 224 for connecting with a forklift to lift the end of the fixed support frame 200.

[0073] When the modular vehicle carrier is transporting vehicles, it can be connected to the fixed support frame 200 via a forklift, thereby lifting one end of the fixed support frame 200, allowing the rolling wheels 225 to roll against the working surface. The modular vehicle carrier is then moved by the forklift, allowing it to roll into the container via the rolling wheels 225. This effectively improves the mobility of the modular vehicle carrier, increases vehicle loading and unloading efficiency, and reduces vehicle transportation costs.

[0074] In some embodiments, one end of the fixed support frame 200 is provided with a roller 225, and the other end of the fixed support frame 200 is detachably connected to the vehicle transport frame 400. The vehicle transport frame 400 is provided with a hook structure 224 so that a forklift can lift the end of the fixed support frame 200 through the hook structure 224 and the vehicle transport frame 400, and the roller 225 can be rolled against the working ground.

[0075] See Figures 6 to 12 In this embodiment, the first connecting structure 220 extends laterally, and its two ends are fixedly connected to the two first support tubes 210 respectively. The first connecting structure 220 is a frame structure to improve its structural strength and ensure the stability of the fixed support frame 200.

[0076] In some embodiments, the first connecting structure 220 is located between the two first fixed tubes and is fixedly connected to the opposing sidewalls of the two first fixed tubes. This facilitates the stacking of the vehicle transport frame 400 and the fixed support frame 200, thereby facilitating the entry of vehicles from the working ground onto the vehicle transport frame 400.

[0077] In other embodiments, the lower surface of the first connecting structure 220 is flush with the lower surfaces of the two first fixing tubes, so that the fixing support frame 200 can evenly transfer the weight it bears to the floor of the container.

[0078] In some embodiments, the first connecting structure 220 is disposed near the roller 225 on the first support tube 210. When a forklift lifts one end of the fixed support frame 200 so that the roller 225 abuts against the floor of the container, the first connecting structure 220 can improve the structural strength and load-bearing capacity of the fixed support frame 200.

[0079] See Figures 6 to 12 In this embodiment, the first connecting structure 220 includes a plurality of first connecting rods 221 and a plurality of first reinforcing rods 222. The plurality of first connecting rods 221 extend laterally. The plurality of first connecting rods 221 are arranged at intervals along the longitudinal direction. The two ends of the plurality of first connecting rods 221 are respectively fixedly connected to the first support tube 210. The plurality of first reinforcing rods 222 extend longitudinally and are connected to the plurality of first connecting rods 221 to improve the structural strength of the first connecting rods 221, thereby ensuring the structural stability of the fixed support frame 200.

[0080] In some embodiments, there are multiple first connection structures 220. All of the multiple first connection structures 220 extend laterally. The multiple first connection structures 220 are arranged at intervals along the longitudinal direction.

[0081] See Figures 6 to 12 In this embodiment, a forklift connector 223 is provided on the first connecting structure 220, and the forklift connector 223 extends along the arrangement direction of the first support tube 210. Both ends of the forklift connector 223 extend downward to penetrate into the first connecting structure 220. The forklift connector 223 can move up and down relative to the first connecting structure 220. Under the action of gravity, the forklift connector 223 can move downward and abut against the upper sidewall of the first connecting structure 220 to limit the downward movement of the forklift connector 223; a locking nut is connected to the lower end of the forklift connector 223, and the locking nut can abut against the first connecting structure 220 to limit the upward movement of the forklift connector 223.

[0082] After the modular vehicle transport frame is used up, when it is necessary to move or stack the fixed support frame 200, the forklift lifts the fixed support frame 200 through the forklift connector 223 to improve the stacking efficiency of the fixed support frame 200 and reduce transportation costs.

[0083] The forklift connector 223 is located above the first connecting rod 221 and extends laterally. Both ends of the forklift connector 223 extend downward to pass through the first connecting rod 221. The middle part of the forklift connector 223 can abut against the upper surface of the first connecting rod 221 to limit the downward travel of the forklift first connecting rod 221.

[0084] The lower surface of the first connecting rod 221 is recessed with a hidden groove 2211 relative to the locking nut. The hidden groove 2211 is used to accommodate the locking nut. When the forklift connector 223 moves upward, the locking nut abuts against the bottom wall of the hidden groove 2211 to limit the upward movement of the forklift connector 223.

[0085] In some embodiments, when the forklift connector 223 abuts against the first connecting rod 221 under the action of gravity, the length of the forklift connector 223 extending into the first connecting rod 221 is less than the vertical height of the first connecting rod 221. This improves the reliability and stability of the fixed support frame 200.

[0086] Figure 13 This is a schematic diagram of the structure of the first height adjustment frame of the present invention. Figure 14 This is a schematic diagram of the structure of the second height adjustment frame of the present invention.

[0087] See Figures 1 to 9 , Figure 13 and Figure 14 In this embodiment, the height adjustment component 300 is disposed on the fixed support frame 200 to support the vehicle transport frame 400 and adjust the height of both ends of the vehicle transport frame 400, the tilt angle of the vehicle transport frame 400, and the center of gravity position of the vehicle.

[0088] The height adjustment assembly 300 includes a sliding block 310 extending along the extension direction of the first support tube 210. The sliding block 310 has a groove relative to the square-tube-shaped first support tube 210. The sliding block 310 is slidably mounted on the first support tube 210 via the groove. The groove is rectangular to fit the square-tube-shaped first support tube 210, thereby effectively improving the connection strength between the sliding block 310 and the first support tube 210.

[0089] In some embodiments, both the sliding block 310 and the first support tube 210 are provided with multiple screw holes, which are arranged longitudinally at intervals. This allows the sliding block 310 to be bolted to the first support tube 210, facilitating relative movement and mutual positioning between the two. In other embodiments, the screw holes on both the sliding block 310 and the first support tube 210 extend laterally to allow the fixing block and the first support tube 210 to pass through, thereby facilitating the connection and disassembly of the sliding block 310 and the first support tube 210. This improves the installation and disassembly efficiency of the modular vehicle transport frame.

[0090] See Figures 1 to 9 , Figure 13 and Figure 14In this embodiment, the height adjustment assembly 300 further includes a lifting rod 320 and a fixed rod 330, both extending upwards. The lower ends of the lifting rod 320 and the fixed rod 330 are fixedly connected to the sliding block 310, with a gap between them. The upper end of the lifting rod 320 is connected to the upper end of the fixed rod 330, so that the lifting rod 320, the fixed rod 330, and the sliding block 310 form a triangular shape. This improves the structural strength of the height adjustment assembly 300 and enhances the reliability of the modular transport frame.

[0091] A limiting member 350 is provided on the lifting rod 320. The limiting member 350 can move on the lifting rod 320 and can be limited on the lifting rod 320. The vehicle transport frame can abut against and be limited on the limiting member 350 so that the height and angle of both ends of the vehicle transport frame 400 can be adjusted.

[0092] See Figures 1 to 9 , Figure 13 and Figure 14 In this embodiment, the height adjustment assembly 300 may include a first height adjustment frame 360 ​​and a second height adjustment frame 370. The first height adjustment frame 360 ​​and the second height adjustment frame 370 are respectively disposed at both ends of the first support tube 210. Both the first height adjustment frame 360 ​​and the second height adjustment frame 370 can move towards or away from each other on the first support tube 210 to adjust the position of both ends of the vehicle transport frame 400, thereby adjusting the center of gravity of the vehicle.

[0093] The first height adjustment bracket 360 can be set at the front end of the vehicle. The second height adjustment bracket 370 is set at the rear end of the vehicle. By adjusting the positions of the first adjustment bracket and the second height adjustment bracket 370, the operator can adjust the height of the front and rear ends of the vehicle relative to the fixed support frame 200, thereby adjusting the vehicle's tilt angle and center of gravity position.

[0094] The vehicle transport frame 400 has a head end and a tail end, respectively. The head end of the vehicle transport frame 400 corresponds to the head end of the vehicle, and the tail end of the vehicle transport frame 400 corresponds to the tail end of the vehicle. The head end and tail end of the vehicle transport frame 400 are used to support and limit the head end and tail end of the vehicle, respectively.

[0095] In some embodiments, the height of the first height adjustment bracket 360 may be greater than the height of the second height adjustment bracket 370. The first height adjustment bracket 360 can adjust the height of the front end of the vehicle so that the front end of the vehicle is positioned close to the top of the container. This facilitates the placement of other vehicles inside the container and improves the space utilization of the container.

[0096] See Figures 1 to 9 , Figure 13 and Figure 14In this embodiment, the sliding block 310 may include a first sliding block 311 and a second sliding block 312. The first height adjustment frame 360 ​​may include the first sliding block 311. The second height adjustment frame 370 may include the second sliding block 312. The first sliding block 311 may be disposed near the hook structure 224. The second sliding block 312 may be disposed near the sliding wheel. Both the first sliding block 311 and the second sliding block 312 may move longitudinally along the first support tube 210.

[0097] The lifting rod 320 may include a first lifting rod 321. The limiting member 350 may include a first limiting member 351 and a second limiting member 352. The first height adjusting frame 360 ​​may include a first lifting rod 321, a first limiting member 351, and a second limiting member 352. The lower end of the first lifting rod 321 is fixedly connected to a first sliding block 311 so that it can move longitudinally with the first sliding block 311. The first limiting member 351 and the second limiting member 352 can move along the first lifting rod 321 and can rotate circumferentially around the first lifting rod 321. The first limiting member 351 may be located below the second limiting member 352, and the first limiting member 351 and the second limiting member 352 can respectively abut against and limit the vehicle transport frame 400.

[0098] When the operator adjusts the height of the vehicle's front end using the first height adjustment frame 360, the vehicle transport frame 400 is first lifted using a forklift. The first limiting member 351 moves upward on the first lifting rod 321 and rotates to align with the vehicle transport frame 400. Then, the first limiting member 351 is positioned on the first lifting rod 321 to abut and connect with the vehicle transport frame 400, thus supporting the vehicle transport frame 400.

[0099] Workers use a forklift to lift the front end of the vehicle transport frame 400, moving it upwards away from the first limiting frame. The second limiting member 352 moves upwards on the first lifting rod 321, rotating around the first lifting rod 321, and then aligning itself with the vehicle transport frame 400. The second limiting member 352 is positioned relative to the first lifting rod 321, thus abutting and connecting with the vehicle transport frame 400 to support it. The first limiting member 351 and the second limiting member 352 allow for adjustment of the vehicle's front end height, facilitating vehicle height and tilt angle adjustments. Furthermore, the first limiting member 351 and the second limiting member 352 enhance the safety and reliability of the vehicle height adjustment process, ensuring the safety of workers.

[0100] In some embodiments, the limiting member 350 includes a first sleeve 3511, a first abutting member 3512, and a first limiting piece 3513. The first sleeve 3511 is sleeved on the lifting rod 320. The first sleeve 3511 is rotatable around the circumference of the limiting member 350.

[0101] The first abutment 3512 can be fixedly connected to the outer peripheral wall of the first sleeve 3511. The upper surface of the first abutment 3512 can abut against and support the vehicle transport frame 400. The first abutment 3512 can limit the downward movement of the vehicle transport frame 400.

[0102] The first limiting piece 3513 is disposed at the end of the first abutting member 3512 opposite to the first sleeve 3511. The first limiting piece 3513 can abut against the vehicle transport frame 400. The first limiting piece 3513, the fixing rod 330, and the lifting rod 320 can limit the lateral movement of the vehicle transport frame 400 to improve the reliability and stability of the modular vehicle transport frame.

[0103] The structure of the second limiting member 352 can be the same as that of the first limiting member 351.

[0104] In some embodiments, the second limiting member 352 and the first limiting member 351 can also be used to adjust the height of the vehicle transport frame 400 and the front end of the vehicle. When it is necessary to adjust the height of the front end of the vehicle, the vehicle transport frame 400 is moved and positioned on the first limiting member 351. Then, the height of the second limiting member 352 is adjusted to accommodate different types of vehicles. Finally, the front end of the vehicle transport frame 400 is lifted above the height of the second limiting member 352 by a forklift. The second limiting member 352 is rotated and positioned, and the forklift lowers the vehicle transport frame 400, which rests against the second limiting member 352 to adjust the height of the vehicle transport frame 400.

[0105] The lifting rod 320 may include a second lifting rod 322. The limiting member 350 may include a third limiting member 353. The second height adjusting frame 370 may include the second lifting rod 322 and the third limiting member 353. The lower end of the second lifting rod 322 is fixedly connected to the second sliding block 312 so that the second lifting rod 322 can move longitudinally along with the second sliding block 312. The third limiting member 353 is movably disposed on the second lifting rod 322 and can be limited on the second lifting rod 322 to abut and limit the tail end of the vehicle transport frame 400. The third limiting member 353 can be adapted to the first limiting member 351 and the second limiting member 352 respectively to adjust the height of the vehicle transport frame 400 and the center of gravity of the vehicle.

[0106] In some embodiments, the third limiting member 353 may include a second sleeve 3531, a second abutment 3532, and a second limiting piece 3533. The second sleeve 3531 may be sleeved on the second lifting rod 322 to be able to move vertically on the second lifting rod 322. The second abutment 3532 is disposed on a side wall of the second sleeve 3531 facing the vehicle transport frame 400. The second abutment 3532 can abut against and limit the vehicle transport frame 400. The second limiting piece 3533 is disposed at one end of the second abutment 3532 opposite to the second sleeve 3531. In a plane perpendicular to the transverse direction, the projection of the second abutment 3532 is located within the enclosure of the second limiting piece 3533, so that the second abutment 3532 and the second limiting piece 3533 can limit the longitudinal movement of the vehicle transport frame 400.

[0107] In some embodiments, both the first lifting rod 321 and the second lifting rod 322 are provided with multiple screw holes, which are arranged vertically at intervals. A positioning member 323 is detachably installed in the screw hole of the first lifting rod 321. The lower end faces of the first limiting member 351, the second limiting member 352, and the third limiting member 353 can respectively abut against the positioning member 323, so that the positioning member 323 can support the first limiting member 351, the second limiting member 352, and the third limiting member 353.

[0108] In some embodiments, the positioning member 323 may pass through the first limiting member 351 and the first lifting rod 321. The positioning member 323 may pass through the second limiting member 352 and the first lifting rod 321. The positioning member 323 may pass through the third limiting member 353 and the second lifting rod 322. In some embodiments, the positioning member 323 may be a bolt structure or a columnar structure.

[0109] See Figures 1 to 9 , Figure 13 and Figure 14 In this embodiment, the fixing rod 330 may include a first fixing rod 331 and a second fixing rod 332. The first height adjustment frame 360 ​​may include the first fixing rod 331. The lower end of the first fixing rod 331 may be fixedly connected to the upper surface of the first sliding block 311, and the upper end of the first fixing rod 331 may be fixedly connected to the upper end of the first lifting rod 321. This makes the first fixing rod 331, the first sliding block 311, and the first lifting rod 321 triangular in shape, thereby ensuring the structural strength and reliability of the first height adjustment frame 360.

[0110] The second height adjustment frame 370 includes a second fixed rod 332. The lower end of the second fixed rod 332 can be fixedly connected to the upper surface of the second sliding block 312, and the upper end of the second fixed rod 332 can be fixedly connected to the upper end of the second lifting rod 322. This makes the second fixed rod 332, the second sliding block 312, and the second lifting rod 322 triangular, so as to ensure the structural strength and reliability of the second height adjustment frame 370.

[0111] In some embodiments, the first height adjustment frame 360 ​​further includes a second reinforcing rod 361, which is connected between the first fixed rod 331 and the first lifting rod 321 to enhance the structural strength of the first fixed rod 331 and the first lifting rod 321.

[0112] See Figures 1 to 9 and Figure 13 In this embodiment, the height adjustment assembly 300 may further include a retaining member 341. The retaining member 341 is detachably disposed on the fixing rod 330 and extends in a direction away from the vehicle transport frame 400. The retaining member 341 is used to abut and limit the movement against the side wall of the container.

[0113] A retaining member 341 is disposed on the first fixing rod 331. The retaining member 341 is detachably connected to the first fixing rod 331. The retaining member 341 extends laterally. The retaining member 341 is adjustable in its lateral position relative to the first fixing rod 331 to adjust the distance between the first fixing rod 331 and the end of the retaining member 341 opposite to the center of the modular transport frame.

[0114] On the one hand, the abutment 341 creates a gap between the vehicle and the side wall of the container to protect the vehicle and prevent the modular transport frame from scratching it during movement. On the other hand, after abutting against the side wall of the container, the abutment 341 can effectively improve the structural strength of the modular transport frame inside the container and ensure the stability of the modular transport frame during transportation.

[0115] In some embodiments, the abutment 341 is a bolt structure, and the abutment 341 is threadedly connected to the first fixing rod 331. The abutment 341 passes through the first fixing rod 331. A abutment plate is provided on the first fixing rod 331 relative to the abutment 341, and the abutment plate is fixedly connected to the outer peripheral wall of the first fixing rod 331. The abutment plate extends in a plane perpendicular to the transverse direction, and the abutment 341 extends transversely to pass through the abutment plate. The abutment 341 is threadedly connected to the abutment plate to facilitate adjustment of the position of the abutment 341 relative to the abutment plate.

[0116] In other embodiments, there are multiple abutment members 341, which are arranged at intervals along the extension direction of the first fixing rod 331.

[0117] In other embodiments, the abutment 341 may be disposed on the second fixing rod 332. Its arrangement is the same as that of the abutment 341 and the first fixing rod 331.

[0118] See Figures 1 to 9 and Figure 13 In this embodiment, the height adjustment assembly 300 may include a fixing plate 362. The fixing plate 362 extends along the extension direction of the fixing rod 330, and a plurality of fixing through holes are provided on the fixing plate 362. The fixing plate 362 is threadedly connected to the vehicle transport frame 400 through the fixing through holes to ensure that the vehicle transport frame 400 is stably and reliably positioned on the height adjustment assembly 300.

[0119] Figure 15 This is a schematic diagram of the structure of the vehicle carrier of the present invention when one wheel is removed while carrying a vehicle. Figure 16 yes Figure 15 Enlarged view of the structure at point C. Figure 17 yes Figure 15 The diagram shows a structural schematic from another perspective. Figure 18 yes Figure 17 Enlarged view of the structure at point D.

[0120] See Figures 1 to 8 , Figures 15 to 18 In this embodiment, the vehicle transport rack 400 is used to carry and limit the vehicle.

[0121] On the one hand, the vehicle transport frame 400 can be connected to and positioned on the height adjustment component 300 to form a modular vehicle transport frame in combination with the height adjustment component 300 and the fixed support frame 200, so as to adjust the height, angle and center of gravity of the vehicle.

[0122] On the other hand, the vehicle transport rack 400 can also be used independently for carrying, restraining, and transporting vehicles. The vehicle transport rack 400 can contact and restrain the container floor independently, so that the vehicle can be placed flat inside the container, thereby facilitating the stacking of multiple vehicles inside the container and improving the space utilization of the container.

[0123] See Figures 1 to 8 , Figures 15 to 18 In this embodiment, the vehicle transport frame 400 is detachably connected to the height adjustment assembly 300. The front end of the vehicle transport frame 400 is detachably connected to the first height adjustment frame 360. The rear end of the vehicle transport frame 400 is detachably connected to the second height adjustment frame 370. This allows the first height adjustment frame 360 ​​and the second height adjustment frame 370 to adjust the height of the front and rear ends of the vehicle transport frame, as well as the angle and center of gravity position of the vehicle transport frame 400.

[0124] The height adjustment component 300 and the vehicle transport frame 400 enable the vehicle's center of gravity to be located in the middle of the fixed support frame 200.

[0125] The vehicle transport frame 400 may include at least two second support tubes 410 and two second connecting structures 420. The second support tubes 410 may extend along the extending direction of the first support tube 210. The at least two second support tubes 410 may be arranged at intervals along the arrangement direction of the first support tube 210. The two second connecting structures 420 may be located at opposite ends of the second support tubes 410. The second connecting structures 420 may be slidably sleeved onto the second support tubes 410. The two second connecting structures 420 are used to respectively support and limit the wheels 10 at the front and rear ends of the vehicle.

[0126] When a vehicle enters the modular vehicle carrier, the two second connecting structures 420 are moved on the second support tube 410 to adjust the distance between the two second connecting structures 420, thereby adapting to various types of vehicles.

[0127] The front and rear ends of the vehicle are connected to two second connecting structures 420 respectively, so as to confine the front and rear ends of the vehicle to the vehicle transport frame 400 respectively.

[0128] Workers can use a forklift to lift the front and rear ends of the vehicle transport frame 400 to adjust their height. This allows the vehicle transport frame 400 and the height adjustment assembly 300 to work together to adjust the vehicle's tilt angle and center position, ensuring the vehicle is reliably and stably positioned within the container.

[0129] See Figures 1 to 8 , Figures 15 to 18 In this embodiment, the second support tube 410 extends longitudinally. One end of the second support tube 410 is provided with a rolling wheel 225, and the other end is provided with a hook structure 224. So that when the vehicle transport frame 400 moves on the work surface or container floor, the forklift can connect with the hook structure 224 to lift one end of the vehicle transport frame 400, so that the rolling wheel 225 rolls on the work surface.

[0130] In some embodiments, the roller 225 is located at one end of the second support tube 410 near the second height adjustment bracket 370. The hook structure 224 is located at one end of the second support tube 410 near the first height adjustment bracket 360.

[0131] In other embodiments, the vehicle transport frame 400 has a hook structure 224 at its front end and a roller 225 at its rear end. A fixed support frame 200 also has a roller 225 at its end near the rear end of the vehicle transport frame 400, and the end of the fixed support frame 200 near the front end of the vehicle transport frame 400 is detachably connected to the front end of the vehicle transport frame 400.

[0132] The forklift connects to the hook structure 224 on the vehicle transport frame 400 to lift the front end of the vehicle transport frame 400. One end of the fixed support frame 200 is also lifted by the vehicle transport frame 400, while the other end of the fixed support frame 200 has its roller 225 resting against the work surface. The operator uses the hook structure 224 on the vehicle transport frame 400 to roll the vehicle transport frame 400 and the fixed support frame 200 on the work surface. This simplifies the structure of the modular vehicle transport frame and reduces its production cost.

[0133] In some embodiments, a limiting groove 411 is formed on the lower side of one end of the second support tube 410 near the second height adjustment bracket 370. The limiting groove 411 is used to engage with the third limiting member 353. After the vehicle transport frame 400 engages with the third limiting member 353 through the limiting groove 411, the vehicle transport frame 400 can rotate around the second abutment member 3532 to adjust the height of the front end of the vehicle transport frame 400.

[0134] The second support tube 410 engages with the third limiting member 353 to better support the rear end of the vehicle and ensure the safety, stability and reliability of the modular transport frame.

[0135] See Figures 1 to 8 , Figures 15 to 18 In this embodiment, the vehicle transport frame 400 may include two second connecting structures 420, which are respectively disposed at both ends of the second support tube 410. The second connecting structure 420 near the first height adjustment frame 360 ​​is slidably disposed on the second support tube 410. The second connecting structure 420 near the second height adjustment frame 370 is fixedly connected to the second support tube 410. Workers can adjust the distance between the two second connecting structures 420 to accommodate the wheelbase of various vehicles.

[0136] The second connecting structure 420, located near the second height adjustment frame 370, may include at least two second connecting rods 421 and a plurality of third reinforcing rods 424. The second connecting rods 421 may extend laterally. The plurality of second connecting rods 421 may be arranged longitudinally at intervals. The plurality of second connecting rods 421 are located between two second support rods. The two ends of each second connecting rod 421 abut against and connect to the opposing sidewalls of the two second support rods.

[0137] Multiple third reinforcing rods 424 extend longitudinally. Multiple third reinforcing rods 424 are arranged laterally at intervals to enhance the structural strength of the second connecting rod 421.

[0138] The second connecting structure 420, located near the second height adjustment frame 370, is used to support and limit the rear end of the vehicle. When the vehicle is housed inside the container, the height of the rear end of the vehicle is lower than the height of the front end. The second connecting structure 420, which limits the rear end of the vehicle, is fixedly connected to the second support tube 410 to ensure the reliability and stability of the vehicle transport frame 400.

[0139] Two second connecting rods 421 can respectively abut against the front and rear sides of the wheel 10 to support the vehicle. In some embodiments, wheel abutment plates 422 for abutting against the sidewalls of the wheel 10 are provided on the opposing sides of the two connecting rods. The wheel abutment plates extend laterally. The wheel abutment plates are adapted to the circular sidewalls of the wheel 10. The wheel abutment plates 422 can increase the contact area with the sidewalls of the wheel 10, thereby making the vehicle stably and reliably positioned on the second connecting structure 420.

[0140] Both ends of the two second connecting rods 421 are provided with wheel limiting members 423. The wheel limiting members 423 can be detachably connected to the wheel 10. The wheel limiting members 423 can limit the wheel 10 to the second connecting rods 421 to prevent the vehicle from moving relative to the vehicle transport frame 400, thus ensuring the stability and reliability of the vehicle transport frame 400.

[0141] In this embodiment, the second connecting structure 420 near the first height adjusting frame 360 ​​may include two third sleeves 425, at least two second connecting rods 421, and a plurality of third reinforcing rods 424. The third sleeves 425 are slidably fitted onto the second support tube 410. The third sleeves 425 extend along the extension direction of the second support tube 410. The second connecting rods 421 extend laterally. Both ends of the second connecting rods 421 are fixedly connected to the two third sleeves 425, respectively. The third reinforcing rods 424 extend longitudinally and are spaced laterally. The third reinforcing rods 424 are connected to the second connecting rods 421 to improve the structural strength of the second connecting structure 420.

[0142] The second connecting rod 421 is provided with a forklift connector 223 for limiting the wheel 10 at the front end of the vehicle to the second connecting frame.

[0143] In some embodiments, the third sleeve 425 and the second support tube 410 can be engaged. Both the third sleeve 425 and the second support tube 410 have opposing pin holes. A fixing pin 427 is detachably provided on the third sleeve 425, and the fixing pin 427 can be inserted into the pin holes on both the third sleeve 425 and the second support tube 410 to confine the third sleeve 425 to the second support tube 410.

[0144] In some embodiments, the third sleeve 425 is detachably disposed on the upper side of the second support tube 410, and the third sleeve 425 is movable laterally relative to the second support tube 410. In other embodiments, the structure of the third sleeve 425 may be configured with reference to the sliding block 310.

[0145] See Figures 1 to 8 , Figures 15 to 18 In this embodiment, the vehicle transport frame 400 includes limiting hole plates 426 located on both lateral sides of the vehicle transport frame 400. The limiting hole plates 426 are corresponding to the fixing hole plates 362, and multiple limiting through holes are formed in the limiting hole plates 426. The fixing through holes are bolted to the limiting through holes to limit the vehicle transport frame 400 on the limiting member 350. After the limiting hole plates 426 are connected to the fixing hole plates 362, the vehicle transport frame 400 can be limited to the first limiting member 351 or the second limiting member 352 to limit the upward movement of the vehicle transport frame 400, thereby ensuring the reliability and stability of the modular vehicle transport frame.

[0146] The limiting hole plate 426 is disposed on the third sleeve 425. The limiting hole plate 426 can abut against the fixing hole plate 362 to improve the connection strength between the vehicle transport frame 400 and the height adjustment assembly 300.

[0147] In some embodiments, limiting through holes are arranged in a longitudinal array on limiting hole plate 426. Fixing through holes are arranged in a vertical array on fixing hole plate 362.

[0148] In other embodiments, the limiting through hole is a waist-shaped hole structure to facilitate the connection between the limiting hole plate 426 and the fixing hole plate 362, thereby improving the connection efficiency between the limiting hole plate 426 and the fixing hole plate 362. It also facilitates the height and angle adjustment of the vehicle transport frame 400.

[0149] In some embodiments, both second connecting structures 420 are slidably mounted on the two second support tubes 410 to accommodate the wheelbase of various vehicle types. Each second connecting structure 420 includes a third sleeve 425, a second connecting rod 421, and a third reinforcing rod 424 to facilitate adjustment of the vehicle's angle and center of gravity.

[0150] The fixing plate 362 can also be mounted on the second fixing rod 332 to limit the tail end of the vehicle transport frame 400.

[0151] See Figure 15 and Figure 17 In this embodiment, the middle part of the second connecting structure 420 can extend upward along an arc to improve the structural strength and load-bearing capacity of the second connecting structure 420.

[0152] The middle portion of the second connecting rod 421 protrudes upward in an arc shape to improve its structural strength. This allows the vehicle transport frame 400 to support vehicles of varying weights. In some embodiments, a forklift can extend under the arc-shaped structure of the second connecting rod 421 to lift the forklift connecting frame.

[0153] See 1 to Figure 9 In this embodiment, the modular transport frame also includes a floor fixing member 511, which is detachably positioned relative to the fixed support frame 200. The floor fixing member 511 is detachably connected to the container floor, thereby confining the fixed support frame 200 within the container, facilitating the fixing and disassembly of the modular transport frame.

[0154] In some embodiments, the floor fixing member 511 can press against the first connecting rod 221 and the first support tube 210 to press the first connecting structure 220 onto the floor and limit the longitudinal and / or lateral movement of the fixing support frame 200.

[0155] In other embodiments, the floor fastener 511 can also be used to hold the vehicle transport rack 400 against the floor, thus confining the vehicle transport rack 400 to the floor of the container. This facilitates the horizontal placement of the vehicle inside the container.

[0156] In some embodiments, the container may contain two or more vehicles. The vehicles within the container include a first vehicle and a second vehicle. A modular transport frame is capable of supporting and restraining the first vehicle. The modular transport frame is capable of adjusting the height of the front and rear ends of the first vehicle, as well as adjusting the tilt angle and center of gravity position of the first vehicle.

[0157] The container can also include two vehicle transport racks 400. One vehicle transport rack 400 is disposed within the height adjustment assembly 300 for carrying and restraining the first vehicle. The other vehicle transport rack 400 can abut against and be restrained on the floor of the container to allow the second vehicle to be horizontally restrained within the container.

[0158] Because the transverse dimension of the vehicle transport frame 400 is smaller than the distance between the two first support tubes 210, the vehicle transport frame 400 can extend into the fixed support frame 200. When the first vehicle is confined to the modular transport frame, the second vehicle and another vehicle transport frame 400 can extend into the fixed transport frame. This allows a portion of the second vehicle to be located below the first vehicle, improving the space utilization efficiency within the container and enabling the container to carry more vehicles.

[0159] In this embodiment, after the container arrives at its destination, the vehicle is unloaded from the modular transport frame. Workers can disassemble the modular transport frame to allow for the separate placement and storage of the first height adjustment frame 360, the second height adjustment frame 370, the vehicle transport frame 400, and the fixed support frame 200, thereby facilitating the transportation of the modular transport frame and reducing transportation costs.

[0160] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.

[0161] See Figures 1 to 18 This application enables the movement and containment of multiple different types of vehicles within a container, thereby facilitating vehicle placement and transportation, improving vehicle transportation efficiency, and reducing vehicle transportation costs.

[0162] When the first vehicle is placed, the vehicle transport frame 400 abuts against the fixed support frame 200. The distance between the two second connecting structures 420 is adjusted to accommodate different types of first vehicles. The first vehicle drives onto the modular transport frame, and the wheels 10 of the first vehicle abut against the second connecting rods 421 respectively. The wheel limiting members 423 limit the wheels 10 of the first vehicle to be positioned on the second connecting structures 420, so that the second connecting structures 420 respectively support and limit the first vehicle.

[0163] After the first vehicle is positioned behind the vehicle transport rack 400, a forklift abuts against the second connecting structure 420 at the rear end of the vehicle transport rack 400. The forklift is capable of lifting the rear end of the vehicle transport rack 400. Depending on the type of the first vehicle, the operator can vertically move the third limiting member 353 and position it against the second lifting lever 322. Then, the forklift lowers the rear end of the vehicle transport rack 400 so that it rests against the third limiting member 353.

[0164] Workers use a forklift and hook structure 224 to lift the modular transport frame and the front end of the first vehicle, so that the rolling wheels 225 of the fixed support frame 200 are pressed against the working ground. Workers then use the forklift to control the modular transport frame to roll into the container.

[0165] As the modular transporter moves within the container, the abutment 341 abuts against the side wall of the container to prevent the side wall of the first vehicle from rubbing against the container. Once the modular transporter reaches the end of the container, the forklift lowers it. The fixed support frame 200 abuts against the container floor, and the floor fixing member 511 confines the fixed support frame 200 to the floor to prevent the modular transporter from swaying during transport, thus improving the safety and reliability of vehicle transport.

[0166] Once the modular vehicle transport rack is positioned on the floor, workers can lift the front end of the vehicle transport rack 400 using a forklift. During this lifting process, the first limiting member 351 is rotated and positioned to ensure the vehicle transport rack 400 abuts against and is contained within it, thus protecting the workers' safety. The height of the second limiting member 352 is adjusted, and it is rotated and positioned to accommodate the type of the first vehicle. The forklift lowers the vehicle transport rack 400, which rests against the second limiting member 352. This allows for further adjustment of the height of the front end of the vehicle transport rack 400, bringing the front end of the first vehicle closer to the top of the container.

[0167] The movement of the vehicle transport rack 400 relative to the height adjustment assembly 300 adjusts the height and tilt angle of the first vehicle's front and rear ends, maximizing the space under the vehicle transport rack 400 to accommodate different types of second vehicles. This improves the space utilization rate within the container.

[0168] After the vehicle transport frame 400 is adjusted, the limiting hole plate 426 is bolted to the fixing hole plate 362 to limit the vertical movement of the vehicle transport frame 400 with the second limiting member 352.

[0169] Once the modular vehicle transport rack is positioned inside the container, the second vehicle will also be positioned inside the container. The second vehicle can only move and be positioned via the vehicle transport rack 400.

[0170] The distance between the two second connecting structures 420 within the vehicle transport frame is adjusted to accommodate various types of second vehicles. The second vehicle drives into the vehicle transport frame 400, with its front and rear wheels 10 respectively abutting against the second connecting rods 421. It is then restrained on the vehicle transport frame 400 by wheel limiting members 423. The front end of the second vehicle is located at the rear end of the vehicle transport frame 400, and the rear end of the second vehicle is located at the front end of the vehicle transport frame 400, allowing the first and second vehicles to be positioned relative to each other.

[0171] The forklift connects to the vehicle transport rack 400 via a hook structure 224. The forklift lifts the front end of the vehicle transport rack 400 so that the rear end of the vehicle transport rack 400 rests against the working ground. The forklift then moves the second vehicle into the container via the vehicle transport rack 400.

[0172] The vehicle transport rack 400, carrying the second vehicle, enters the front end of the modular transport rack. Longitudinally, the rear end of the vehicle transport rack 400 enters the fixed support frame 200, and the vehicle transport rack 400 is fitted against the bottom plate and secured to it by bottom plate fasteners. This arrangement ensures that the front end of the second vehicle is located below the front end of the first vehicle, thereby improving the space utilization of the container.

[0173] Once the container arrives at its destination, the vehicle transport rack 400 and modular vehicle transport rack are removed from the container. The modular vehicle transport rack can be disassembled into a first height adjustment rack 360, a second height adjustment rack 370, the vehicle transport rack 400, and a fixed support rack 200. This facilitates the stacking and transportation of the first height adjustment rack 360, the second height adjustment rack 370, the vehicle transport rack 400, and the fixed support rack 200, thereby improving the storage and transportation of the modular vehicle transport rack, increasing work efficiency, and reducing production costs.

[0174] In this application, when accommodating and transporting vehicles through containers, the vehicles are first moved into and positioned on the vehicle transport rack 400. The vehicle transport rack 400 can be positioned on the fixed support frame 200 via the height adjustment component 300. The modular transport rack can be moved into the container, and the fixed support frame 200 can be positioned on the container floor. The placement height and angle of the vehicles can be adjusted via the height adjustment component 300, allowing the container to accommodate more vehicles. The modular transport rack facilitates positioning and separation from the container. After the container arrives at its destination, the vehicles are unloaded from the modular transport rack, which can be disassembled into the fixed support frame 200, the height adjustment component 300, and the vehicle transport rack 400. This facilitates the stacking and transportation of the internal structures of the modular transport rack, reduces empty return rates, and lowers transportation costs.

[0175] Figure 19 This is a flowchart illustrating steps S100 to S500 of the method of use of the present invention.

[0176] See Figure 19 This application also provides a method of using a modular vehicle carrier, which is applied to any of the modular vehicle carriers mentioned above. The method of use is as follows: In step S100, the first height adjustment frame 360 ​​and the second height adjustment frame 370 are moved to adjust the position of the vehicle transport frame 400 relative to the fixed support frame 200.

[0177] In step S200, the vehicle transport rack 400 is used to carry and limit the vehicle.

[0178] In step S300, one end of the vehicle transport frame 400 is lifted and positioned on the second height adjustment frame 370 to adjust the height of the rear end of the vehicle.

[0179] Step S400: Lift the modular transport frame and move it into the container.

[0180] In step S500, the other end of the vehicle transport frame 400 is lifted and positioned on the first height adjustment frame 360 ​​to adjust the height and angle of the front end of the vehicle. The first height adjustment frame 360, the second height adjustment frame 370, and the vehicle transport frame 400 enable the center of gravity of the vehicle to be located in the middle of the fixed support frame 200.

[0181] By adjusting the first height adjustment frame 360 ​​and the second height adjustment frame 370, the position of the vehicle transport frame 400 relative to the fixed support frame 200 is adjusted. On the one hand, this allows the modular transport frame to reserve space for the rear end of the vehicle when carrying it, preventing the vehicle from abutting against the end wall of the container, thereby improving the space utilization of the container. On the other hand, the first height adjustment frame 360 ​​and the second height adjustment frame 370 can adjust the center of gravity of the vehicle.

[0182] Before the vehicle is moved into and positioned within the container, the position of the rear end of the vehicle transport frame 400 and the second height adjustment frame 370 is adjusted, thereby adjusting the height and angle of the vehicle transport frame 400 and the rear end of the vehicle. When the modular transport frame is positioned inside the container, the rear end of the modular transport frame is located close to the end wall of the container. Therefore, adjusting the height of the rear end of the vehicle transport frame 400 outside the container can effectively improve the installation efficiency of the modular transport frame and reduce the positioning costs of the modular transport frame and the vehicle.

[0183] After the height of the vehicle transport rack 400 and the rear end of the vehicle are adjusted, the modular transport rack is lifted and moved into the container. Once the modular transport rack is positioned against the container floor, the front end of the vehicle transport rack 400 is lifted using a forklift. The forklift is then positioned on the first height adjustment frame 360 ​​to adjust the height of the front end of the vehicle. This adjusts the height and angle of the front end of the vehicle.

[0184] The positions of the first height adjustment frame 360 ​​and the second height adjustment frame 370 relative to the fixed support frame 200, and the height and tilt angle of the vehicle transport frame 400 relative to the height adjustment assembly 300, together adjust the vehicle's center of gravity. Longitudinally, the vehicle's center of gravity is located in the middle of the fixed support frame 200, so that the vehicle's weight is evenly transferred to the container floor through the fixed support frame 200, thereby ensuring the stability of the modular transport frame.

[0185] Figure 20 This is a flowchart illustrating step S110 of the method of use of the present invention.

[0186] See Figure 19 and Figure 20 In this embodiment, step S100 further includes step S110.

[0187] In step S110, the second height adjustment bracket 370 is installed at the rear end of the vehicle. The second height adjustment bracket 370 on the first support tube 210 is moved to adjust the distance between the second height adjustment bracket 370 and the adjacent end of the first support tube 210.

[0188] When the second height adjustment frame 370 moves relative to the first support tube 210, it can accommodate various types of vehicles. Longitudinally, by adjusting the distance between the second height adjustment frame 370 and the rear end of the fixed support frame 200, the distance from the rear end of the vehicle to the adjacent container end wall can be controlled. When adjusting the front height of the vehicle, the rear end of the vehicle rotates around the second limiting member 352, allowing the rear end of the vehicle to be accommodated within the space between the second height adjustment frame 370 and the container end wall. This prevents the rear end of the vehicle from rubbing against the container end wall and improves the space utilization within the container.

[0189] Figure 21 This is a flowchart illustrating step S210 of the method of use of the present invention.

[0190] See Figure 19 and Figure 21 In this embodiment, step S200 further includes step S210.

[0191] In step S210, the vehicle transport frame 400 includes two second connecting structures 420, which are capable of moving longitudinally so that they can be adapted to and limit the vehicle; the two second connecting structures 420 and the height adjustment component 300 can adjust the center of gravity of the vehicle so that the center of the vehicle is located in the middle of the fixed support frame 200.

[0192] Before the vehicle transport frame 400 carries and positions the vehicle, the distance between the two second connecting structures 420 can be adjusted. On one hand, this allows it to accommodate various vehicle wheelbases, facilitating the placement of the vehicle's wheels 10 on the transport frame 400 after the vehicle enters it. On the other hand, the second connecting structures 420 can adjust the vehicle's center of gravity as they move relative to the second support tube 410. This allows them to work in conjunction with the height adjustment component 300 and the fixed support frame 200 to position the vehicle's center of gravity at the center of the fixed support frame 200.

[0193] Figure 22 This is a flowchart illustrating step S410 of the method of use of the present invention.

[0194] See Figure 19 and Figure 22 In this embodiment, step S400 includes step S410.

[0195] In step S410, one end of the fixed support frame 200 is provided with a rolling wheel 225, and the other end of the fixed support frame 200 is used to connect to a forklift. During the process of transporting a vehicle into a container via the modular vehicle carrier, the fixed support frame 200 is lifted by a forklift so that the rolling wheel 225 can abut against the working ground and the floor of the container, thereby moving the modular vehicle carrier and the vehicle into the container.

[0196] The forklift connects to the front end of the modular transport frame to lift it, causing the rollers 225 on the fixed support frame 200 to rest against the working ground. Workers then use the forklift to roll the modular transport frame and the vehicle on it into the container via the rollers 225. This effectively reduces the kinetic energy required for the forklift to move the modular transport frame and vehicle, improving transportation efficiency. It also facilitates adjusting the placement and angle of the modular transport frame within the container.

[0197] Figure 23 This is a flowchart illustrating step S510 of the method of use of the present invention.

[0198] See Figure 19 and Figure 23 In this embodiment, step S500 further includes step S510.

[0199] In step S510, the first height adjustment frame 360 ​​is installed at the front end of the vehicle. The first height adjustment frame 360 ​​includes a first lifting rod 321, a first limiting member 351, and a second limiting member 352.

[0200] When adjusting the height of the vehicle's front end, a forklift is used to lift the front end of the vehicle transport frame 400 above the first limiting member 351. The first limiting member 351 rotates around the first lifting rod 321, limiting the first limiting member 351 on the first lifting rod 321, so that the first limiting member 351 can support and limit the front end of the vehicle transport frame 400.

[0201] Then, by lifting the front end of the vehicle transport frame 400, the front end of the vehicle is brought close to the top of the container. The second limiting member 352 rotates around the first lifting rod 321, limiting the second limiting member 352 on the first lifting rod 321, so that the second limiting member 352 can support and limit the front end of the vehicle transport frame 400, thereby adjusting the angle of the vehicle.

[0202] The first limiting member 351 and the second limiting member 352 facilitate the adjustment of the height of the front end of the vehicle transport frame 400, improving the efficiency of vehicle height and angle adjustment. Furthermore, when adjusting the vehicle height, the first limiting member 351 prevents the vehicle transport frame 400 from falling directly onto the fixed support frame 200 after detaching from the second limiting member 352, thus ensuring the safety of personnel and the property of the vehicle.

[0203] In this embodiment, when the container arrives at its destination, because the vertical height of the exit of some containers is less than the height between the container floor and the top plate, the upper side wall of the container exit will scrape against the vehicle when the modular transport vehicle unloads the container. The modular transport frame may not be able to unload the container directly using a forklift.

[0204] Figure 24This is a flowchart illustrating step S600 of the method of use of the present invention.

[0205] See Figure 19 and Figure 24 The method of using the modular vehicle transport frame also includes step S600.

[0206] In step S600, after the container reaches its destination, the front end of the vehicle transport rack 400 is lifted by a forklift. Then, the second limiting member 352 and the first limiting member 351 are rotated so that the second limiting member 352 rotates to the side of the first lifting rod 321 facing away from the vehicle transport rack 400. The first limiting member 351 rotates and is positioned on the side facing the vehicle transport rack 400, allowing the vehicle transport rack 400 to rest against and be positioned on the first limiting member 351. This lowers the height of the vehicle transport rack 400 and the front end of the vehicle, facilitating the modular transport rack and the vehicle to move to the outside of the container through the container's exit.

[0207] Figure 25 This is a flowchart illustrating steps S710 to S720 of the method of use of the present invention.

[0208] See Figure 19 , Figure 24 and Figure 25 In this embodiment, the method of using the modular vehicle transport frame further includes step S710.

[0209] In step S710, after the modular vehicle transport frame is moved to the outside of the container, the first end of the vehicle transport frame 400 is lifted by a forklift, and the first limiting member 351 and the second limiting member 352 are rotated so that the first limiting member 351 and the second limiting member 352 are both located on the side of the first lifting rod 321 away from the vehicle transport frame 400. Then the first end of the vehicle transport frame 400 is lowered so that the first end of the vehicle transport frame 400 can be set close to the fixed support frame 200.

[0210] The method of using the modular vehicle transport frame also includes step S720.

[0211] See Figure 19 , Figure 24 and Figure 25 In step S720, the rear end of the vehicle transport frame 400 is lifted by a forklift, and then the third limiting member 353 is moved downward to reduce the height of the vehicle transport frame 400 and the rear end of the vehicle.

[0212] When the front and rear ends of the vehicle transport frame 400 are lowered onto the fixed support frame 200, the vehicle wheels 10 are separated from the vehicle transport frame 400, and the vehicle can drive out of the modular transport frame.

[0213] Figure 26 This is a flowchart illustrating step S800 of the method of use of the present invention.

[0214] See Figure 19 , Figure 24 , Figure 25 and Figure 26 The method of using the modular vehicle transport frame also includes step S800.

[0215] In step S800, after the vehicle leaves the modular vehicle transport frame, the vehicle transport frame 400, the first height adjustment frame 360, the second height adjustment frame 370, and the fixed support frame 200 are disassembled and separated. Then, the vehicle transport frame 400, the first height adjustment frame 360, the second height adjustment frame 370, and the fixed support frame 200 are stacked separately.

[0216] The vehicle transport frame 400, the first height adjustment frame 360, the second height adjustment frame 370, and the fixed support frame 200 are stacked to facilitate the transport of the vehicle transport frame 400, the first height adjustment frame 360, the second height adjustment frame 370, and the fixed support frame 200. This improves vehicle transport efficiency and reduces vehicle transport costs.

[0217] Although this application has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since this application can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
