Embodiment 1

[0111] This embodiment discloses a foldable box body and a towed caravan. The overall structure of the towed caravan is as follows: figure 1 Shown, comprise wheel and carriage (car body), this carriage is a kind of collapsible casing.

[0112] The state of the trailer trailer when it is fully folded is as follows: figure 1 with figure 2 As shown, it includes a rectangular parallelepiped first box 1 , a rectangular parallelepiped second box 2 and a rectangular connecting plate 3 . The bottom edge of the connecting plate 3 is hinged on the bottom edge of the first box body 1 , and the top edge of the connecting plate 3 is hinged on the top edge of the second box body 2 . The second box body 2 is placed on the first box body 1 as a whole. In order to lower the center of gravity, the weight and volume of the second box body 2 are smaller than the first box body 1 .

[0113]The front part of the trailer is a triangular area, which is used to hang the tractor and facilitate stee...

Embodiment 2

[0127] The caravan of this embodiment does not need wheels, and the foldable box body is directly arranged on the pickup truck. The schematic diagram of the folded structure is as follows Figure 16 As shown, the expanded schematic diagram of the structure is shown in Figure 17 shown.

Embodiment 3

[0129] This embodiment provides an inflatable composite board, which is formed by compounding existing inflatable cloth and aluminum alloy. The plate-shaped inflatable cloth is the inflatable cloth board. The inflatable cloth board is a cuboid structure surrounded by inflatable cloth. There is a cavity inside the cuboid structure for inflation, so it can be called an inflatable cavity. The dimensions of the cavity in the thickness direction are much smaller than the dimensions in the length and width directions. A schematic diagram of its cross-section (sectional view) such as Figure 18 As shown, the inflatable cloth panel includes an inflatable cavity 103 and an inflatable cloth 102. The inflatable cavity 103 is a sealed cavity surrounded by the inflatable cloth 102. By controlling the structure of the inflatable cloth 102, when the cavity is filled with gas, The inflatable cloth panel is a plate-like structure. Since the inflatable cloth is generally made of polymer compo...

Abstract

The invention discloses an inflatable composite board, a folding container and a recreational vehicle. The inflatable composite board comprises an inflatable fabric board, the inflatable fabric boardcomprises an inflatable cavity and an inflatable fabric defining the inflatable cavity, and the external surfaces of the inflatable fabrics of one or two sides of the inflatable fabric board are provided with metal layers. The inflatable composite board can keep warm and insulate heat, is a light-weight material, and has a good anti-piercing effect and anti-aging effect; and in particular, when used on the folding container and the recreational vehicle, the inflatable composite board can greatly realize the light weight of structures.

Description

technical field [0001] The invention relates to an inflatable composite board, a foldable box body and a caravan, belonging to the application field of composite materials. Background technique [0002] Nowadays, RVs are quite common in people's lives. People can use RVs during travel or outdoor life, which solves the troublesome problem of setting up tents during travel and outdoor life. However, most of the products sold on the market are fixed volume RVs or drawer-type expandable RVs. The space of this type of RV is immutable or the amount of expansion is very small. If the RV is too small, the space of the RV after expansion will be narrow. If the RV is too large, it will be even more uncomfortable to drag. Convenience, the existing RV adopts a foldable method, which solves the disadvantages caused by the oversized RV, but the foldable wall itself is not compressible, causing the folded wall to occupy a large amount of storage space. The foldable part is folded many tim...
