[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0034] This embodiment provides a foldable camping vehicle, such as Figures 1 to 15 As shown, the vehicle includes a body 1 and a wheel system. The wheel system includes a wheel assembly 3 and a tow bar 4. The wheel assembly 3 is detachably mounted at the bottom of the body 1, and the tow bar 4 is detachably mounted on either the wheel assembly 3 or the body 1. The tow bar 4 is used to move either the wheel assembly 3 or the body 1 so that the body 1 can be used as a camping vehicle. The body 1 has a storage cavity 11 inside, and the top of the body 1 is open for placing items into the storage cavity 11. The body 1 is composed of two hinged parts, with the hinge located in the middle of the body 1 so that the two parts can be flipped around the hinge. After flipping, the top of the body 1 is closed, while the bottom is open. The hinge in the middle of the body 1 has a snap-fit ​​structure 12. The detached tow bar 4 is assembled with the snap-fit ​​structure 12 and placed horizontally in the middle of the body 1 for lifting the body 1. At this time, the body 1 serves as a storage box 2, and the wheel assembly 3 can be selectively placed into the storage cavity 11.

[0035] This embodiment of the foldable camping vehicle includes a camping vehicle mode and a storage box 2 mode, allowing users to switch between modes as needed. When used as a camping vehicle, the user can tow the vehicle using the tow bar 4 for convenient transport of items. On rough or muddy roads, the user can remove the wheel assembly 3 and tow bar 4, transforming it into a storage box 2 with a simple flip. The tow bar 4 is then assembled with the snap-fit ​​structure 12 and positioned horizontally in the middle of the vehicle body 1. The storage box 2 is then moved by lifting, avoiding the risk of the wheels getting stuck in mud or damaged. The structure is simple and easy to use. The flipped vehicle body 1 has a closed top and an open bottom design; simply inverting the vehicle body 1 allows it to be used as a storage box 2. The snap-fit ​​structure 12 and the tow bar 4 ensure a more stable lifting process and make operation more convenient for the user.

[0036] In this embodiment, when used as a campervan, the vehicle body 1 is in an unfolded state, occupying a large area and capable of accommodating larger items. When flipped over, the vehicle body 1 functions as a storage box 2, fulfilling its storage function while occupying a smaller area. The storage box 2 is also taller, which is beneficial for storing longer and narrower items. Furthermore, the vehicle body 1 in this embodiment features a lidless design, accommodating items of more different shapes and increasing its carrying capacity. In other embodiments, a cover can be added to the vehicle body 1 to protect the items, depending on actual needs.

[0037] like Figure 2 , Figure 3 and Figure 5As shown, this embodiment also includes a first locking device 5 and a second locking device 6. When the vehicle body 1 is used as a camping vehicle, the first locking device 5 is fixedly installed between the two parts of the vehicle body 1, effectively preventing relative displacement of the two parts during movement and ensuring the stability and safety of the camping vehicle during operation. When the vehicle body 1 is used as a storage box 2, the second locking device 6 is fixedly installed between the two parts on the top of the flipped vehicle body 1, making the storage box 2 more stable when storing items, less likely to fall apart, and ensuring the safety of the items. Figure 5 As shown, the second locking device 6 in this embodiment is provided in two places, which can further improve the sturdiness of the storage box 2. In this embodiment, both the first locking device 5 and the second locking device 6 are latches, which can ensure stability and security in both campervan mode and storage box 2 mode. Moreover, the latch structure facilitates easy locking and unlocking, improving the convenience of use. The structure is simple and easy to operate. Of course, other locking structures can also be used in other embodiments.

[0038] like Figures 6 to 9 As shown, the tow bar 4 includes a folding mechanism 41 and a telescopic mechanism 42. The telescopic mechanism 42 includes a multi-stage sleeve rod, which is slidably connected from the inside to the outside. The folding mechanism 41 is pivotally connected to the telescopic mechanism 42. The folding mechanism 41 is provided with a limiting device, which is used to control the angle limit of the folding mechanism 41 within the rotatable range on the telescopic mechanism 42. When the vehicle body 1 is used as a camp vehicle, the telescopic mechanism 42 is detachably mounted on the wheel set 3. When the vehicle body 1 is used as a storage box 2, the folding mechanism 41 is rotated to a position parallel to the telescopic mechanism 42. The ends of the folding mechanism 41 and the telescopic mechanism 42 are assembled with the snap-fit ​​structure 12 and are horizontally mounted in the middle of the vehicle body 1.

[0039] The tow bar 4 in this embodiment includes a folding mechanism 41 and a telescopic mechanism 42. The telescopic mechanism 42 of the multi-stage tow bar provides a flexible adjustment range, allowing the length of the tow bar 4 to be adjusted as needed, making the campervan more adaptable to different terrains and scenarios. The multi-stage tow bar in this embodiment consists of three stages. The folding mechanism 41 is pivotally connected to the end of the telescopic mechanism 42 that is away from the outermost stage when the innermost stage is extended. In the storage box 2 mode, the folding mechanism 41 rotates to a position parallel to the telescopic mechanism 42 and is limited by a limiting device. At this time, the length of the three-stage tow bar when folded and the length of the folding mechanism 41 match the dimensions of the vehicle body 1. The ends of the folding mechanism 41 and the telescopic mechanism 42 are assembled with the snap-fit ​​structure 12 and are horizontally positioned in the middle of the vehicle body 1 for lifting the box, making it convenient to use.

[0040] like Figures 6 to 8As shown, the limiting device of the folding mechanism 41 in this embodiment includes a gripping sleeve 411 and a limiting seat 412. The limiting seat 412 is fixedly installed at one end of the telescopic mechanism 42, allowing the user to operate it directly by gripping it with their hand, greatly improving the intuitiveness and convenience of operation. The gripping sleeve 411 is pivotally connected to the limiting seat 412. The gripping sleeve 411 is provided with a limiting protrusion 413, and the limiting seat 412 is provided with a limiting groove 414. The gripping sleeve 411 is used to slide and control the limiting protrusion 413 to move and embed into the limiting groove 414 to achieve angular limiting of the gripping sleeve 411 within the rotatable range on the limiting seat 412. By sliding the gripping sleeve 411, the user can easily control the movement of the limiting protrusion 413 to achieve precise adjustment and limiting of the folding angle. The tight cooperation between the limiting protrusion 413 and the limiting groove 414 ensures that the gripping sleeve 411 can be securely locked after being adjusted to the required angle. The structure is simple and the operation is convenient.

[0041] like Figure 7 As shown, the folding mechanism 41 of this embodiment also includes a first sleeve cover 415, a second sleeve cover 416, a connecting rod 417, a compression spring 418, and a pressure plate 419. The first sleeve cover 415 is screwed to one end of the gripping sleeve 411 and has a first through hole along the axial direction of the gripping sleeve 411. The second sleeve cover 416 is screwed to the other end of the gripping sleeve 411 and has a second through hole along the axial direction of the gripping sleeve 411. The first sleeve cover 415 and the second sleeve cover 416 are tightly connected to the gripping sleeve 411 by screwing, which is convenient for installation and removal. It provides stable support and protection for the connecting rod 417 and the compression spring 418, and ensures the stability and durability of the gripping sleeve 411 during long-term use. The limiting protrusion 413 is disposed on the second sleeve cover 416, and the compression spring 418 is sleeved on the outer periphery of the connecting rod 417. The connecting rod 417 and the compression spring 418 are placed inside the gripping sleeve 411. One end of the connecting rod 417 passes through the first through hole of the first sleeve cover 415 and is fixedly connected to the pressure plate 419. The other end of the connecting rod 417 passes through the second through hole of the second sleeve cover 416 and is provided with a connecting plate 4171. The connecting plate 4171 is pivotally connected to the limiting seat 412. The compression spring 418 pushes the limiting protrusion 413 of the second sleeve cover 416 to be movably embedded in the limiting groove 414. By setting the compression spring 418, not only is sufficient elastic force provided for the limiting protrusion 413 so that it can be reliably embedded in the limiting groove 414, but it also plays a certain role in buffering and shock absorption. When the gripping sleeve 411 is subjected to external impact or vibration, the compression spring 418 can absorb some energy and protect the internal components from damage.

[0042] like Figure 8As shown, in this embodiment, the limiting seat 412 has three sets of limiting grooves 414 on the rotation path of the connecting plate 4171. The three sets of limiting grooves 414 are located on the left and right sides and the top of the limiting seat 412, respectively. There are two limiting grooves 414 in each group, and two limiting protrusions 413 in each group. The two limiting protrusions 413 on the second sleeve cover 416 are symmetrically arranged on both sides of the second through hole. The size of the two limiting grooves 414 matches the size of the two limiting protrusions 413. The two limiting grooves 414 and the clearance groove are arranged vertically to form a "cross shape". In the storage box 2 mode, the gripping sleeve 411 of the folding mechanism 41 rotates to the top of the limiting seat 412. The compression spring 418 pushes the limiting protrusion 413 into the limiting groove 414 at the top of the limiting seat 412, so that the folding mechanism 41 and the telescopic mechanism 42 form a straight traction rod 4. The ends of the folding mechanism 41 and the telescopic mechanism 42 are respectively assembled with the snap-fit ​​structure 12 and horizontally arranged in the middle of the vehicle body 1 for lifting the vehicle body 1.

[0043] like Figure 10 and Figure 11 As shown, the snap-fit ​​structure 12 is a magnetic suction groove 121, which is located at the hinge in the middle of the vehicle body 1. The ends of the folding mechanism 41 and the telescopic mechanism 42 are respectively provided with magnetic suction components 122 that match the magnetic suction groove 121. The folding mechanism 41 is rotated to a position parallel to the telescopic mechanism 42 and fixed horizontally in the middle of the vehicle body 1 by the magnetic suction components 122 and the magnetic suction groove 121. In this embodiment, the cooperation between the magnetic suction groove 121 and the magnetic suction components 122 allows the folding mechanism 41 and the telescopic mechanism 42 to be quickly and stably horizontally installed in the middle of the vehicle body 1 without the need for additional fasteners or screws, making loading and unloading convenient, greatly simplifying the operation process and improving the efficiency of use.

[0044] like Figure 12 and Figure 13 As shown, the wheel assembly 3 includes a front wheel assembly 31, which includes a front bottom tube 311, a front connector 312, a pivot 313, and a front mounting seat. The front bottom tube 311 is located at the bottom of one of the split components. Two front connectors 312 are fixedly mounted on the front bottom tube 311, and each of the two front connectors 312 has a pivot 313. Each of the two pivots 313 has a front mounting seat that rotates around the axis of the pivot 313. In this embodiment, the front connector 312 is a first U-shaped frame, and the pivot 313 is located between two horizontal plates of the first U-shaped frame. The front mounting seat is used to mount the two front wheels, which facilitates a compact connection and installation of the two front wheels, reducing space occupation. Furthermore, the front wheels can steer around the axis of the pivot 313, adapting to different driving needs or terrain conditions and improving flexibility in campervan mode.

[0045] like Figure 12 and 13As shown, the front mounting base includes a front axle sleeve 314, a front mounting shaft 315, and a front buffer spring 316. The front axle sleeve 314 and the front buffer spring 316 are fitted onto the rotating shaft 313. The two front axle sleeves 314 respectively radially protrude from the front mounting shafts 315. The axes of the two front mounting shafts 315 are parallel to the axis of the front bottom tube 311. The bearings of the two front wheels are respectively mounted on the two front mounting shafts 315. In this embodiment, by setting the buffer spring, on the one hand, it can protect the rotating shaft 313 and the axle sleeve from wear caused by vibration, thereby improving service life; on the other hand, it also provides additional support and stability for the axle sleeve and the rotating shaft 313, making the camper vehicle more stable and reliable during operation.

[0046] like Figure 12 and 13 As shown, the front wheel assembly 31 also includes a transmission component 317 and a drive component 318. Two transmission components 317 protrude radially from the two front axle sleeves 314 along the shaft 313. The two transmission components 317 are hinged to one end of the drive component 318, improving transmission efficiency, shortening the transmission path, and increasing response speed, thus making steering more flexible. As shown, a transmission rod 319 can also be provided between the transmission component 317 and the drive component 318 for power transmission, further saving processing materials and costs. The drive component 318 is hinged in the middle of the front undertube 311. A drive unit is provided at the other end of the drive component 318. A telescopic mechanism 42 is detachably mounted on the drive unit. The drive unit controls the rotation of the transmission component 317 at one end of the drive component 318 to drive the two front wheels to rotate synchronously around the axis of the shaft 313. Operation is simple; when the telescopic mechanism 42 on the drive unit is pulled, the other end of the drive component 318 drives the transmission component 317 to rotate via the connecting rod 417, thereby driving the two front wheels to steer synchronously.

[0047] like Figure 15 As shown, the wheel assembly 3 also includes a rear wheel assembly 32, which includes a rear bottom tube 321, a rear connector 322, a limiting plate 323, a rear mounting seat 324, and a rear buffer spring 325. The rear bottom tube 321 is located at the bottom of another vehicle body. Two rear connectors 322 are fixedly mounted on the rear bottom tube 321. The rear connectors 322 are second U-shaped brackets. Limiting plates 323 are fixedly mounted on the two rear connectors 322. The rear mounting seat 324 and the rear buffer spring 325 are sleeved on the limiting plates 323. The limiting plates 323 are used to limit the rotation of the two rear wheels, and the rear buffer spring 325 plays a role in buffering and shock absorption. The two rear mounting seats 324 have protruding rear mounting shafts. The axes of the two rear mounting shafts are parallel to the axis of the rear bottom tube 321, and the bearings of the two rear wheels are respectively mounted on the two rear mounting shafts.

[0048] like Figure 14 and Figure 15As shown, in this embodiment, the front bottom tube 311 of the front wheel assembly 31 and the rear bottom tube 321 of the rear wheel assembly 32 are both provided with mounting frames 33. The mounting frames 33 are provided with slide rails 34, and the bottom of the vehicle body 1 is provided with a sliding groove 35. The front wheel assembly 31 and the rear wheel assembly 32 can be quickly installed and removed by the slide rails 34 and the sliding grooves 35, which improves the convenience of use.

[0049] like Figures 1 to 5 As shown, the vehicle body 1 includes a first segment 13 and a second segment 14. Both the first segment 13 and the second segment 14 include a base plate 15 and side plates 16. Several side plates 16 surround the base plate 15 to form the storage cavity 11. One side of the first segment 13 and the second segment 14 not surrounded by the side plates 16 forms an open end. The first segment 13 and the second segment 14 are hinged to each other through the top of the side plates 16 at the open ends. The first segment 13 and the second segment 14 can be rotated upwards and folded around their hinge point. In this embodiment, the base plate 15 of the first segment 13 and the second segment 14 are both square and have the same size, ensuring that they can form a storage box 2 after folding and flipping. Correspondingly, the number of side plates 16 of the first segment 13 and the second segment 14 are three each. In other embodiments, the base plate 15 can also be set to a trapezoidal or other shapes.

[0050] The usage process of this invention is as follows:

[0051] When this invention is used as a camper vehicle, such as Figure 1 and Figure 2 As shown, the first part 13 and the second part 14 of the vehicle body 1 are hinged and fixed together and locked by the first locking device 5. The folding mechanism 41 of the traction rod 4 is pivotally connected to one end of the telescopic mechanism 42. The folding mechanism 41 controls the limiting protrusion 413 to move into the limiting groove 414 at different positions on the limiting seat 412 through the gripping sleeve 411, thereby limiting the angular range of rotation of the folding mechanism 41 on the telescopic mechanism 42. The other end of the telescopic mechanism 42 is detachably mounted on the drive part of the front wheel assembly 31. The user adjusts the folding mechanism 41 and the telescopic mechanism 42 to a suitable angle and length. The transmission component 317 at one end of the drive component 318 on the front wheel assembly 31 is rotated by the folding mechanism 41 and the telescopic mechanism 42 to drive the two front wheels to achieve synchronous steering.

[0052] When this invention is used as storage box 2, such as Figure 4 and Figure 5As shown, firstly, the tow bar 4 is removed from the drive unit of the front wheel assembly 31. The folding structure is rotated to a position parallel to the telescopic mechanism 42, so that the folding mechanism 41 and the telescopic mechanism 42 form a straight tow bar 4. After the first locking device 5 is unlocked, the first part 13 and the second part 14 of the vehicle body 1 are folded and flipped upward around their hinge. After flipping, the top of the vehicle body 1 is closed, while the bottom is open, and it is locked by the second locking device 6. A magnetic groove 121 is provided at the hinge in the middle of the vehicle body 1. The ends of the folding mechanism 41 and the telescopic mechanism 42 are respectively provided with magnetic suction parts 122. The straight tow bar 4 is fixed horizontally in the middle of the vehicle body 1 by the magnetic suction parts 122 and the magnetic groove 121.
