In order to meet the needs of citizens when resting in a variety of public spaces, the design idea is modularization. The same square base is matched with four different top modules: seats, solar charging, tabletops, and plant planting. Through structural design, Any combination of different functions and numbers can be realized, and it can also be used alone, which is flexible and convenient. Among them, the solar charging module uses ETFE photovoltaic panels, which are dustproof, waterproof, and pressure-resistant, and are lighter and thinner, and have higher power generation efficiency. Each set of solar charging modules can fully charge 3650 mobile phones every year. The surface treatment of the product is made of environmentally friendly paint, luminous paint is used at the font, and the seat surface is made of environmentally friendly plastic wood. Every detail will implement the concept of environmental protection to the end. The structural design is also excellent. All modules can be raised and lowered in height. Each module can be split, combined and reused. Customized public seats can be obtained at any time by independent hands, which is convenient for after-sales user maintenance and management.
