Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles, and in particular relates to a compartment expansion structure and a recreational vehicle thereof. Background Art

[0002] The height of a motorhome is usually over 3m, and the overall height is relatively high. In actual use, the problem of road height restrictions is often encountered, especially in cities where most parking lots are underground parking lots with a height limit of about 2.15m, which makes it impossible for most motorhomes to enter underground parking lots, making it inconvenient to use the motorhome. In order to adapt to the above usage scenarios, the height of the motorhome needs to be lower than 2.15m, and the internal use space of the motorhome needs to be guaranteed, so the pop-up motorhome came into being. At present, most pop-up motorhomes have tent cloth around them after the roof is raised. After the tent cloth is raised, the internal space is irregular and the interior is not beautiful. In addition, the tent cloth has poor sound insulation and heat insulation effects, is not safe, and has a poor environment inside the car. Utility Model Content

In actual use, the problem of road height restrictions is often encountered, especially in cities where most parking lots are underground parking lots with a height limit of about 2.15m, which makes it impossible for most caravans to enter the underground parking lot, making it inconvenient to use the caravan. In order to adapt to the above usage scenarios, it is necessary to make the height of the whole caravan lower than 2.15m, and it is necessary to ensure the internal use space of the caravan, so the pop-up caravan came into being. At present, most pop-up caravans are surrounded by tent cloth after the roof is raised. After the tent cloth is raised, the internal space is irregular, the interior is not beautiful, and the tent cloth has poor sound insulation and heat insulation effect, is not safe, and has a poor environment inside the car. Therefore, the utility model proposes a box expansion structure. When the space of the caravan needs to be increased, the box expansion structure is raised, and the side of the box is formed by the box board to ensure that it is firm after expansion, and sound insulation and heat insulation; when the space does not need to be expanded, the box expansion structure is folded to facilitate the caravan to pass through the height-restricted road conditions.
