[0002] RV curtains are a device installed inside an RV, usually used to separate and block different areas to increase the privacy, cleanliness and functionality of the interior space. The demand for rational use and functional optimization of the interior space of RVs is increasing, and the existing RV curtains have a single function and cannot meet diverse needs.

[0003] Moreover, when the RV is driving or docked, outside noise can easily pass through the curtains into the living area inside the vehicle, affecting the passengers' comfort experience; and it is difficult to adjust the temperature inside the RV under different seasons and climatic conditions, and the existing curtains have insufficient thermal insulation performance; and when the RV is unattended, there is a risk of items being stolen, and the existing curtains lack effective anti-theft measures.

[0004] Combining the above-mentioned issues, we can find that it is difficult to avoid the above-mentioned problems at the same time when using the existing blackout curtains on the market, thus failing to achieve the desired effect. Therefore, we propose a PVC multifunctional RV blackout curtain which not only has conventional shading and shielding functions, but also integrates multiple functions such as sound insulation, heat preservation, anti-theft alarm and intelligent control.
