Description

[Technical Field]

[0001] The present invention relates to a solar panel, and more particularly to an expandable solar panel whose area can be expanded or contracted as desired. [Background technology]

[0002] The primary function of today's automotive solar panels is to provide auxiliary energy to the vehicle, reducing reliance on traditional fuels or the vehicle's battery. When parked or when driving in an environment with sufficient sunlight, the solar panels can convert sunlight into electricity, which is stored in the onboard battery or supercapacitor, allowing the vehicle's electronic devices (e.g., air conditioning system, onboard entertainment system, lighting, and communication devices) to run continuously. Additionally, solar panels are used to keep the car's start-stop system running, allowing it to generate power even when the car's engine is temporarily shut off, preventing the battery from running out of power and being unable to restart the engine. For electric vehicles, onboard solar panels can further extend the driving range and reduce the need for frequent charging, thereby reducing the burden on the environment and improving overall energy efficiency.

[0003] Additionally, for drivers, having a portable windshield-mounted solar panel on their vehicle offers several significant advantages. First, the windshield receives sufficient sunlight every day, and when positioned at the best incident angle, especially while driving, photoelectric conversion efficiency is maximized. Furthermore, solar panel modules installed in a mobile manner rather than fixed to the roof can be adjusted manually or mechanically according to the direction of the sun, allowing for greater power generation. Furthermore, the windshield area usually has a large, smooth surface, allowing for the installation of a relatively large solar panel. When the vehicle is parked, the driver can remove the portable solar panel and use it outdoors on its own, making it convenient to use.

[0004] However, since the windshields of different vehicle models have different shapes and areas, the area of ​​the vehicle-mounted solar panel to be installed also changes accordingly. For example, the windshield area of ​​a small hatchback or mini SUV is relatively small, and the area that can be accommodated by the solar panel is limited, or it only occupies a portion of the central area, so the maximum power output efficiency is relatively limited. A luxury sedan or SUV has a large windshield, which allows for a larger mounting area and more modules to be installed, resulting in greater power output efficiency. This means that to make it easy for drivers to use, solar panels of an appropriate size to fit each size windshield are required. In other words, for users, the arbitrarily expandable or contractible solar panel not only meets the needs of each vehicle, but also provides users with flexibility in use in different application situations. Summary of the Invention [Problem to be solved by the invention]

[0005] In summary, it is an important issue to provide a solar panel that is simple in structure and can be expanded or contracted at will. [Means for solving the problem]

[0006] The object of the present invention is to provide a solar panel that is simple in structure and can be expanded or contracted at will.

[0007] To achieve the above object, the present invention provides an extended solar panel, which includes a first solar panel, an extended solar panel, and a second solar panel. The first solar panel includes a first positive electrode connection port, a first negative electrode connection port, and a first connection structure disposed on one side of the first solar panel. The extended solar panel includes a positive electrode extension connection port, a negative electrode extension connection port, and a first extension connection structure and a second extension connection structure respectively installed on corresponding two sides of the extended solar panel. The positive electrode extension connection port is electrically connected to the first negative electrode connection port, and the first extension connection structure is connected to the first connection structure. The second solar panel includes a second positive electrode connection port, a second negative electrode connection port, and a second connection structure disposed on one side of the second solar panel. The second positive electrode connection port is electrically connected to the negative electrode extension connection port, and the second connection structure is connected to the second extension connection structure.

[0008] In one embodiment, the first expanding connection structure and the second connecting structure are hook and loop structures, respectively.

[0009] In one embodiment, the second connecting structure and the second expanding connecting structure are hook and loop structures, respectively.

[0010] In one embodiment, the first expansion connecting structure and the first connecting structure are interlocking structures, and the first expansion connecting structure and the first connecting structure are respectively a convex structure and a concave structure.

[0011] In one embodiment, the second connecting structure and the second expanding connecting structure are interlocking structures, and the second connecting structure and the second expanding connecting structure are respectively a protruding structure and a recessed structure.

[0012] As a result, the expansion type solar panel of the present invention connects the first solar panel and the second solar panel through the first expansion connection structure and the second expansion connection structure of the expansion solar panel, and electrically connects the first solar panel and the second solar panel through the positive expansion connection port and the negative expansion connection port. Therefore, the expandable solar panel of the present invention has a simple structure and is a solar panel that can be expanded or contracted at will. [Brief explanation of the drawings]
