[0002] RV, also known as "home on wheels", has the functions of "house" and "car", but its attribute is still a car. It is a mobile vehicle with basic facilities necessary for home. RV is a fashionable vehicle introduced from abroad. The home facilities on the vehicle include: bedding, stove, refrigerator, cabinet, sofa, dining table and chairs, washing facilities, air conditioner, TV, stereo and other furniture and electrical appliances. It can be divided into driving area, living area, bedroom area, sanitary area, kitchen area, etc. RV is a fashionable product that integrates "clothing, food, housing and transportation" and realizes "travel in life and life in travel".

[0003] At present, most of the existing RV square box panels are of integral structure, and their overall weight increases, which in turn affects the fuel consumption of the RV and other problems. In addition, various daily necessities need to be placed in the existing RV square boxes. When encountering roads with poor road conditions during driving, the items will vibrate, and then the square box panels will be bumped and worn, causing some panels to be damaged. Moreover, since the square box panels are of integral structure, they need to be replaced as a whole when they need to be replaced, which leads to excessively high replacement costs and inconvenient replacement, and there are certain deficiencies. For this reason, we propose a lightweight RV square box panel with good load-bearing capacity. Summary of the invention
