DETAILED DESCRIPTION
[0026] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.
[0027] A folding camping vehicle frame, as shown in Figure 1 , Figure 2 , comprises a folding bottom plate assembly 1 and a folding surrounding barrier assembly 2, the folding bottom plate assembly 1 comprises two hingedly connected bottom frame bodies 11, the folding surrounding barrier assembly 2 is movably connected with the folding bottom plate assembly 1 and can be unfolded or folded synchronously with the folding bottom plate assembly 1, the folding surrounding barrier assembly 2 is fixedly connected with a front fixed support 31 and a rear fixed support 32, two roller assemblies 4 are arranged on the front fixed support 31 and the rear fixed support 32, and a pull rod 5 is further arranged on the front fixed support 31, and an extension frame body 6 is hingedly connected to the rear fixed support 32. After unfolding of the vehicle frame, the folding bottom plate assembly 1 is unfolded to form a plane, the folding surrounding barrier assembly 2 is arranged around the folding bottom plate assembly 1, and the front fixed support 31 and the rear fixed support 32 are respectively located on the front side and the rear side of the folding bottom plate assembly 1, and the extension frame body 6 can be in close contact with the folding surrounding barrier assembly 2 to keep the folding state, or can be unfolded to be at the same height as the folding bottom plate assembly 1, thereby increasing the storage space.
[0028] Specifically, as shown in Figure 1As shown, the folding enclosure assembly 2 includes four side rods 21 and two side frames 22. The four side rods 21 are grouped in pairs and located on both sides of the folding base plate assembly 1. The inner ends of the side rods 21 in the same group are hinged to each other, and the outer ends are fixed to the front fixed frame 31 and the rear fixed frame 32, respectively. A hinge seat 23 is fixed in the middle of each side rod 21. The side frame 22 is U-shaped, and both ends of the side frame 22 are inserted into the hinge seats 23 of the two side rods 21, and the side frame 22 is hinged to the hinge seats 23. A connecting sleeve 24 is fixed on each side frame 22 near its end. Figure 3 , Figure 4 As shown, in this embodiment, the body of the connecting sleeve 24 is a hollow cylinder, and its shape is adapted to the cross-section of the side frame 22, which facilitates the insertion of the connecting sleeve 24 and the side frame 22. A locking structure is also provided between the hinge seat 23 and the connecting sleeve 24. One end of the hinge seat 23 has an arc-shaped guide surface 231. The locking structure includes a locking groove 232 opened on the guide surface 231 and a positioning protrusion 241 provided on the outer end of the connecting sleeve 24. The locking groove 232 is "V" shaped, and the positioning protrusion 241 is "V" shaped to match the locking groove. When the folding enclosure assembly 2 is unfolded, the positioning protrusion 241 can be embedded in the locking groove 232 to form a lock with the locking groove 232. Each hinge seat 23 is also provided with a limiting part, which blocks the rotation path of the side frame 22. After the side frame 22 is unfolded into place, it abuts against the limiting part. Furthermore, a connecting rod 25 is provided between the side frame 22 and the bottom frame 11. One side of the connecting sleeve 24 has an outwardly protruding connecting part 242.
