Description

Technical Field

[0001] The utility model relates to the technical field of camping vehicles, in particular to a rear door structure of a folding camping vehicle. Background Art

[0002] A camper van is a foldable, towable cargo vehicle. It is widely used in transporting things because it is easy to use, can carry cargo, is easy to store, and saves time and effort. It is now often used in outdoor activities or short-distance transportation.

[0003] Existing foldable campers are usually composed of four side brackets that are surrounded by each other to form a structure with a cavity in the middle. The storage area of ​​this structure is affected by the size of each side bracket, and the volume of each side bracket cannot be changed after assembly. Therefore, the storage area of ​​the existing foldable campers cannot be changed according to usage requirements. For this reason, engineers have also designed a solution to increase the storage area without changing the size of each side bracket, such as Chinese utility model patent number: CN202321974958.1 (a camping trailer with a tipping function). The difference between it and the conventional camper in the prior art is that the rear side of its frame has a flippable side wall structure. By flipping down the side wall structure, the storage area of ​​its cargo compartment is expanded and the storage of cargo is increased. However, this kind of gathered body can be folded from both sides to the middle, which requires the side wall structure to be retracted. The folding frame in the structure provides a certain space for activities. There are two common ways. One is that the first support rod is a telescopic structure. The other is that a transfer rod is connected between the top of the folding frame and the first support rod as in the disclosed patent, so that the folding frame can be folded. However, both methods have certain problems. After the side wall structure is flipped down, the flipped side loses the support of the folding frame. At this time, it is easy for the wheels on both sides to move closer to the middle during use, especially when used on uneven roads. This situation is more obvious. The reason for this situation is that the transfer rod can rotate freely relative to the folding frame, and when it is flipped down, it is more likely to fold itself when it receives squeezing force, so that it cannot support the frame, resulting in poor use effect, and there is also the problem of low stability of the frame. In the long run, the service life of the vehicle body will be reduced; and the same is true for the telescopic structure.

[0004] Therefore, it is urgent to design a rear door structure of a foldable camper to overcome one or more deficiencies of the above-mentioned prior art. Utility Model Content
