Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically an expandable flexible photovoltaic panel system for roof mounting. Background Technology

[0002] With the rapid development of the new energy vehicle industry, especially the widespread adoption of pure electric vehicles, electric vehicle users generally face the problem of insufficient range during long-distance travel, particularly in remote areas lacking charging infrastructure, where this "range anxiety" is even more pronounced. Currently, most vehicles on the market can only be equipped with a single fixed photovoltaic module. Limited by roof space and power generation efficiency, a single photovoltaic panel cannot meet the power demands for extended periods or high power consumption. Furthermore, users often lack reliable emergency power supplies when dealing with extreme events such as natural disasters. Based on this, a vehicle-mounted flexible photovoltaic power generation system with high power generation and a scalable multi-layer structure has been developed. This system can maximize the deployment of photovoltaic modules when the vehicle is parked, increasing power output and becoming key to solving the above problems. Simultaneously, with continuous breakthroughs in flexible photovoltaic technology, the power generation efficiency of individual modules is expected to significantly improve in the future. This system can optimize and adjust the size and layout of the photovoltaic modules according to their power generation performance to further enhance the overall power generation capacity of the system. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a solution that can solve the problems of small power generation area and low power generation efficiency of existing vehicle roof photovoltaic panels.

[0004] To solve the above problems, the technical solution of this utility model is as follows: an expandable flexible photovoltaic panel system for roof mounting, comprising a frame, the frame including a central fixed structure and side frames, the frame having an extension structure, the central fixed structure being based on the extension structure and capable of unfolding to the left, right and rear, the side frames being capable of unfolding forward and backward, thereby increasing the number of photovoltaic panels, the extension structure including multiple layered structures, the layered structures including sliding frames, and an inverter electrically connected to the photovoltaic panel for providing power.

[0005] Furthermore, the extended structure can be a slide rail structure and a roller slide structure. The slide rail is located on opposite sides of the side frame and is slidably connected to the central fixed structure. The tail of the slide rail is provided with a locking structure. The roller slide structure is located on the support plate of the side frame.

[0006] Furthermore, the photovoltaic panels consist of eight units with a total power of 2-3KW. The thickness of each photovoltaic panel is less than 1 cm, and when not in use, the overall thickness of the frame is less than 30 cm.

[0007] Furthermore, the sliding frame includes a groove, and a pulley is slidably connected within the groove.

[0008] Furthermore, the photovoltaic panel is made of a flexible photoelectric conversion material.

[0009] The advantages of this invention compared to existing technologies are as follows:

[0010] This utility model uses a frame sliding structure and a multi-layer design to achieve modular expansion, allowing the photovoltaic panels to unfold from the sides and rear of the vehicle roof, thereby increasing the power generation area and improving the power generation capacity. The system can not only generate electricity through the photovoltaic panels when the vehicle is stationary and charge the electric vehicle via a 5 kW inverter, but also provide power support for on-board equipment and home appliances. The system is particularly suitable for outdoor travel and home emergency power supply scenarios, as it can be flexibly unfolded when in use and compactly stored when not in use.

[0016] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0017] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0018] like Figures 1 to 3As shown, an expandable flexible photovoltaic panel system for vehicle roof mounting includes a frame 1, which includes a central fixed structure and side frames 2. An extension structure is provided on the frame 1. The central fixed structure, based on the extension structure, can extend the side frames 2 left and right via slide rails 7, and extend the uppermost sliding frame 6 rearward via pulleys. The sliding frames 6 within the side frames can be extended forward and backward via pulleys. The photovoltaic panels 5 are made of flexible photoelectric conversion material, thereby increasing the number of photovoltaic panels 5. The extension structure includes multiple layered structures, each layered structure including the sliding frame 6. An inverter is electrically connected to the photovoltaic panels 5 to provide power.

[0019] The extended structure can be a sliding rail structure or a roller structure. The sliding rail is located on the side of the side frame, and the roller structure is located at the bottom of the frame. There are eight photovoltaic panels 5, with a total power of 2-3KW. The thickness of each photovoltaic panel 5 is less than 1 cm. When not in use, the cumulative thickness of the frame is less than 30 cm. The sliding frame 6 includes a groove 3, and the pulleys 4 are slidably connected within the groove 3 to facilitate the opening and closing of the sliding frame.

[0020] In practical use, the system is installed on the roof of an electric vehicle. When the vehicle is parked, the photovoltaic panels extend outward via sliding rails, using solar energy to charge the vehicle and providing power to the vehicle's electrical appliances via an inverter. The 5-kilowatt inverter can meet the needs of most electrical appliances during outdoor travel, including refrigerators, lighting, and charging equipment.

[0021] For home emergency use: Under normal circumstances, the system can be folded and stored in a corner of the home. In case of extreme weather or power shortages, the system can be unfolded and provide emergency power support to the home through the inverter. Its overall frame is less than 30 cm thick, taking up little space when stored, making it easy to store and use in the home.
