[0027] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0028] like Figure 2 As shown, the folding side rail 7 includes an upper side rod 701 and a lower side rod 702. One end of the upper side rod 701 is rotatably connected to the connecting member 2, and the other end is hinged to another adjacent upper side rod 701. The lower side rod 702 is rotatably connected to the sliding member 4, and the other end is hinged to another adjacent lower side rod 702. The folding side rail 7 consists of two upper side rails and two lower side rails.

[0029] Furthermore, the middle portion of the upper rod 701 and the middle portion of the lower rod 702 are hinged, and the folding side rail 7 can be folded by pushing it inward.

[0030] Specifically, a connecting portion is formed on the mounting seat 3, and the folding base 6 is installed on the connecting portion. The folding base 6 includes a central connecting hinge and four bottom support rods 602. One end of the bottom support rod 602 is connected to a corner of the central hinge 601, and the other end is rotated on the connecting portion. One end of the bottom support rod 602 can only rotate below the central hinge 601, and the other end can only rotate above the connecting portion. Pulling the central hinge 601 upwards can achieve folding of the folding base 6.

[0031] Furthermore, it also includes a handle portion 9, a fixed connecting member 10 is fixed on the mounting seat 3, and the handle portion 9 is installed on the fixed connecting member 10. The handle portion 9 includes a folding rod 901, a multi-section telescopic rod 902 and a side hinge 903. The handle portion 9 is used to facilitate pulling the camp car.

[0032] Furthermore, one end of the folding rod 901 rotates on the fixed connecting member 10, and the other end is rotatably connected to one side of the side hinge 903. The telescopic rod 902 is fixed to the middle of the side hinge 903. The multi-section telescopic rod 902 is adjusted in length by the adjustment device 905 thereon. A handle 904 is fixed to the end of the telescopic rod 902. The folding rod 901 can only rotate above the side hinge 903. Pressing the handle 904 downward can fold the handle part 9. When the handle part 9 is in the unfolded state, hold the handle 904 to pull the camp car. The telescopic rod 902 is subjected to an upward force, which maintains the unfolded state of the folding rod 901, making the whole more stable.

[0033] Furthermore, there are four main support rods 1 and four wheel modules 5, and the folding side rails 7 and folding front rails 8 appear in pairs and are installed on the corresponding two sides, forming a rectangular frame together with the folding base 6.

[0034] In some embodiments, a truck bucket 11 is placed in the rectangular frame. To facilitate the placement of the truck bucket 11, a fixed limiting piece is formed on the connecting piece 2, so that the truck bucket 11 fits more closely with the rectangular frame and reduces the shaking of the truck bucket 11.

[0035] When folding the camping vehicle, first pull the center hinge 601 upwards and press the upper hinge 804 downwards to fold the folding base 6 and the folding front rail 8. Then push the main support rod 1 inwards to fold the folding side rails 7, and press the handle 904 downwards to move the handle part 9 downwards for folding. The telescopic rod 902 can be optionally adjusted in length by the adjustment device 905. Otherwise, the camping vehicle can be unfolded.

[0036] Based on the above structure, this application also provides another embodiment. Specifically, refer to Figure 4 As shown, the aforementioned folding front rail is turned upside down so that the first crossbar and the second crossbar are close to the side of the folding base, and the rest remain unchanged.

[0037] Thus far, various embodiments of the present application have been described in detail. To avoid obscuring the concept of the present application, some details well known in the art have not been described. Based on the above description, those skilled in the art will fully understand how to implement the technical solutions disclosed herein.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present application, and the aforementioned embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not drive the essence of the corresponding technical solutions away from the spirit and scope of the technical solutions of the various embodiments of the present application.
