The terms "first" and "second" and the like in the specification and claims of this invention and the accompanying drawings are used to distinguish different objects, not to describe a specific order.

[0029] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] like Figure 1-5 The following are examples provided by the present invention.

[0032] The present invention provides a camper van, comprising: a foldable frame 10, a control handle 20 hinged at the front end of the frame 10, a box 30 detachably mounted on the frame 10, a main control box 40, and a plurality of wheels 50. Specifically, the frame 10 is a square frame structure, the box 30 is a square that matches the shape of the frame 10, and the material of the box 30 can generally be a flexible material such as cloth or plastic. The upper edge of the box 30 is connected to the upper edge of the frame 10, and each surface of the box 30 is in contact with the interior of the frame 10. Connecting tubes 11 are respectively provided at the four corners of the frame 10, and each wheel 50 is provided with a connecting rod 51. The number of wheels 50 is the same as the number of connecting tubes 11. Each connecting rod 51 is respectively plugged into the lower end of a corresponding connecting tube 11. The wheels 50 are mounted at the bottom of the four corners of the frame 10 to maintain the stability of the frame 10. A limiting buckle 12 is provided in the connecting tube 11, and a limiting groove 52 is provided around the upper end of the connecting rod 51. The limiting buckle 12 is movably engaged with the limiting groove 52. When the limiting buckle 12 is engaged with the limiting groove 52, the connecting rod 51 cannot be pulled out of the connecting tube 11. When the limiting buckle 12 is separated from the limiting groove 52, the connecting rod 51 can be pulled out of the connecting tube 11, thereby removing the wheel 50. It is worth mentioning that the limiting groove 52 is annular so that the limiting buckle 12 will not be blocked by the limiting groove 52 when the wheel 50 rotates. The cooperation between the limiting buckle 12 and the limiting groove 52 only serves to limit the axial position of the connecting rod 51, and does not affect the circumferential rotation of the connecting rod 51 in the connecting tube 11. After adopting the above-mentioned camping car, the connecting rod 51 provided on the wheel 50 is plugged into the connecting tube 11 provided on the frame 10, and the limiting buckle 12 provided in the connecting tube 11 is movably engaged with the limiting groove 52 at the upper end of the connecting rod 51, so that the wheel 50 is easily disassembled from the frame 10, thereby reducing the volume of the camping car after folding, thereby reducing the occupied packaging space and reducing transportation and storage costs.

[0033] Furthermore, a button 13 is provided on the outside of the connecting tube 11, and an opening is correspondingly provided on the side wall of the connecting tube 11. The button 13 is laterally inserted into the connecting tube 11 from the opening and connected to the limit buckle 12. The inner end of the button 13 is connected to a spring 14, and the other end of the spring 14 abuts against the inner wall of the connecting tube 11. Pressing the button 13 can drive the limit buckle 12 to move inward to the other side until it is separated from the limit groove 52, and the spring 14 is compressed under the pressure of the button 13. Release the button 13, and the elastic force of the spring 14 is released. The spring 14 extends its side length to push the button 13 outward, so that the button 13 is reset and the limit buckle 12 is connected to the limit groove 52. The movable connection between the limit buckle 12 and the limit groove 52 is controlled by the provided button 13, which is simple and quick, and convenient for the user to disassemble and assemble.

[0034] Specifically, wheel 50 includes a roller 53 and an inverted U-shaped fork 54. Roller 53 is rotatably mounted within fork 54 via a rotating shaft, and connecting rod 51 is disposed at the top of fork 54. Furthermore, a bearing 15 is disposed at the lower end of connecting tube 11. Bearing 15 is sleeved onto connecting rod 51, reducing friction generated between the lower ends of connecting rod 51 and connecting tube 11 during relative rotation, thereby ensuring smoother steering of wheel 50.

[0035] Furthermore, the camper in this embodiment is rear-wheel drive, and at least one hub motor 56 is installed in the wheel 50 located at the rear end of the frame 10. The hub motor 56 is electrically connected to the main control box 40. In order to facilitate the steering control of the camper, the wheel 50 located at the front end of the frame 10 is a universal wheel mode and can rotate arbitrarily, while the wheel 50 located at the rear end of the frame 10 is fixed in the direction facing forward. Specifically, the wheel 50 located at the rear end of the frame 10 is further provided with a limit rod 55 on the top of the fork 54. The limit rod 55 is located on one side of the connecting rod 51. The limit rod 55 can be plugged into the frame 10, so that the connecting rod 51 cannot rotate arbitrarily in the connecting tube 11, so as to achieve the purpose of controlling the direction of the rear wheel 50.

[0036] Specifically, the control handle 20 is in an inverted "Y" shape, with its two bifurcated ends hinged to either side of the lower frame at the front end of the frame 10, allowing the control handle 20 to swing up and down. Furthermore, a fixing slot 16 is provided on the upper frame at the front end of the frame 10, with the handle of the control handle 20 being able to snap or magnetically connect to the fixing slot 16. When not in use or folded, the control handle 20 can be secured in the fixing slot 16 to prevent the front end of the control handle 20 from falling to the ground.

[0037] Specifically, a connecting groove 41 is provided on the top of the main control box 40, and the connecting groove 41 is detachably connected to the bottom frame of the frame 10. The width of the connecting groove 41 is adapted to the thickness of the bottom frame of the frame 10, and the two can be just stuck together. Then, holes are drilled in the connecting groove 41 and the bottom frame of the frame 10 and fixed with cotter pins, so that the main control box 40 can be firmly installed at the bottom of the frame 10. In addition, installing the main control box 40 at the bottom of the frame 10 can also serve to block rainwater, preventing the main control box 40 from accidentally getting wet. It is understandable that in order to improve the waterproofness of the entire vehicle circuit, the hub motor 56 and the control handle 20 can be electrically connected to the main control box 40 using the existing detachable male and female waterproof connectors on the market, which have good waterproofness and are easy to disassemble and assemble.
