How do solar bench reconstruct the energy and information nodes of urban public spaces?

DDK-ST4000 adopts a tree-shaped structure design, breaking through traditional imagination. It is different from the traditional solar bench on the market, which are mainly designed with flat photovoltaic panels. Multiple monocrystalline silicon solar panels of different sizes are carefully distributed on the "branch" structure composed of high-strength materials. Through the integration of bionics and architectural aesthetics, while ensuring the power generation efficiency, it takes into account the aesthetics of the shape and the practicality of the function to the maximum extent.
The design has been accurately calculated and repeatedly deduced in terms of space utilization, light receiving angle, and force structure, so that the orientation and angle of the solar panel can absorb sunlight resources to the greatest extent and improve the overall power generation efficiency. At the same time, its lightweight structure and wind-resistant structure also provide a more solid guarantee for outdoor all-weather use.

DDK-ST4000 is not just a chair, it is also an integrated system of "micro energy terminal + smart city node". The multifunctional modules it is equipped with cover the following aspects:
Solar charging function: DDK-ST4000 has a built-in high-efficiency solar energy conversion system, using high-quality monocrystalline silicon photovoltaic modules, and has excellent photoelectric conversion efficiency. Through the scientifically arranged "branch-like" photovoltaic panels, the seat can automatically absorb solar energy all day and store it in the built-in lithium battery pack. The matching USB charging port supports citizens to quickly charge small electronic devices such as mobile phones, tablets, Bluetooth headsets, etc., without the need for external grid power, truly achieving "zero energy consumption" operation. This function not only improves the convenience of citizens in outdoor scenes, but also provides emergency charging support, especially in emergency situations. It is a very practical and considerate service in modern cities.
Night lighting system: DDK-ST4000 is equipped with LED smart light strips in the "branch" shape and at the bottom of the seat. It uses automatic light sensing control technology. When it gets dark or enters night mode, the light strip will automatically turn on. The light brightness is moderate, which neither causes light pollution nor significantly improves the surrounding lighting effect. This system not only enhances the visibility of public spaces at night and improves pedestrian safety, but also visually creates a warm and technological urban atmosphere. The lighting color and dynamic effects can also be adjusted and customized according to festival and scene requirements, combining practicality with landscape art value.
Environmental monitoring module: As an important component of the basic unit of the smart city, DDK-ST4000 can be equipped with a variety of sensor modules, including temperature, humidity, PM2.5, PM10, CO₂ concentration, noise and other environmental monitoring functions. The collected data is uploaded to the city cloud platform or digital twin system via a wireless network and becomes part of the city's environmental perception network. This allows city managers to grasp key data such as local air quality, heat island distribution, pollution fluctuations, etc. in real time, providing strong support for precise governance and scientific decision-making. At the same time, it can also allow citizens to intuitively understand the quality of the environment around them and enhance environmental awareness through public information display screens and other methods.
Intelligent control system: DDK-ST4000 is equipped with an intelligent control system based on the Internet of Things, which can realize multiple remote functions, including real-time viewing of equipment operation status, automatic start and stop of lighting system, adjustment of brightness and duration, energy consumption data statistics and historical record query, fault warning and maintenance notification push, etc. Through the management background or APP port, urban management units can uniformly manage and remotely control the solar bench distributed throughout the city without manual inspection one by one, which greatly saves labor costs and maintenance time and improves the intelligent level of municipal operation and maintenance.
Wireless network hotspot: At a time when mobile office and digital recreation are becoming more and more popular, some versions of DDK-ST4000 also support integrated WIFI wireless network modules to provide convenient public hotspot services. The seats can access 4G/5G communication networks and release WIFI signals to the surrounding areas for citizens to temporarily access the Internet. This not only provides additional digital convenience services for public places, but also makes solar bench no longer just static furniture, but also transforms them into intelligent interactive terminals of "information transmission + energy supply + city perception". It is especially suitable for scenes that require temporary network deployment, such as science and technology parks, campus squares, and exhibition venues.

Wide range of scene adaptation
Thanks to its landscape and artistic style, DDK-ST4000 can be easily integrated into various outdoor environment scenes, including but not limited to:
Urban parks and green spaces, improving the quality of public landscapes;
Commercial plazas and tourist attractions, building interactive rest areas;
Campuses and science and technology parks, serving the intelligent needs of young groups;
Smart communities and industrial parks, as green energy demonstration carriers;
Bus stops and square corners, filling the gaps in convenient facilities.
The appearance structure can also be customized according to customer needs, including color, lighting style, pattern decoration, etc., to help customers achieve exclusive and scene-based customization.
