The structure of this flat solar panel is mainly to connect multiple small solar cells in parallel, in series or in series The parallel connection method is combined on a flat panel, and then the flat-panel solar panels are installed on the roof of the building and the wall of the building's outer wall, usually by charging the battery, and then recharging the equipment in the building through the inverter device. For power supply, another use is to install flat-panel solar panels on the pillars next to the road through brackets, and charge the batteries to supply power to traffic lights. However, the main disadvantages of this flat-panel solar panel are three points. One is that the existing flat-panel solar panel has a large area, and many installation sites are limited by the area, so the scope of application is not wide enough; , because the existing flat-panel solar panels are too large to be carried around, which affects the promotion of its application field; the third is that it cannot meet the needs of some places where solar panels need to be installed and disassembled at any time. The flat-panel solar panels currently used in the energy field are as shown in Figure 1, which are mainly composed of unit solar cells 10 and plastic flat panels 11, and their disadvantages are as shown in Figure 1. The connection method of series, parallel or series-parallel is to spread the unit solar cells on the plastic flat plate 11, lead out the power supply negative lead 12 of the battery board and the positive lead 13 of the battery board on the back of the plastic flat plate 11, and seal them with heat-resistant and waterproof sealant The combined gap 14 around the unit solar cell 10 and the plastic flat plate 11 acts as a moisture-proof and waterproof function for the flat solar cell panel. The disadvantage of this flat solar cell panel is that it has a large area and requires a larger building for installation. site or a fixed installation location; secondly, this flat-panel solar panel cannot meet the needs of carrying around; thirdly, this flat-panel solar panel cannot meet the needs of installation and disassembly at any time in some places. Such solar cells have actually restricted the promotion and application of solar cells in the field of electric work, in the automotive field, and in civilian households, and have affected the promotion of solar cells in the energy field.

Contents of the invention

The purpose of the foldable retractable solar cell panel of the present utility model is to overcome the disadvantage that the existing flat solar cell panel needs a large area of building site or fixed installation site during installation, and it cannot meet the needs of carrying around. However, it cannot meet the shortcomings of some places that need to be installed and disassembled at any time, so as to provide a foldable and retractable solar panel and its components.

The technical solution adopted by the utility model is: combine the unit solar cells into a thin strip solar cell panel, and connect a plurality of thin strip solar cell panels adjacently by conductive hinges, so that the thin strip solar cell panels It can be folded and shrunk along the length direction, and can be unfolded and tiled; a cylinder is provided at different ends of the back of the first and last thin strip solar panels, and a rotatable movable bead is provided with a round hole, which can be just inlaid It is inserted into the cylinder, and can be rotated, and is used to flatten the strip-shaped solar cell panel after it is unfolded, so that it becomes a large-area flat-panel solar cell panel after being unfolded.

The beneficial effects of the utility model are: because the solar battery panel is divided into a plurality of thin solar battery panels, and several thin solar battery panels are connected adjacently by conductive hinges, so that it can be folded and shrunk, and can Unfold the tiles to make it more widely used. After the car is parked in the hot summer, install the foldable and retractable solar panel on the front and rear windshields of the car in the car compartment, and keep the power supply by powering the semiconductor refrigeration system The low temperature demand in the car; secondly, the battery of the electric car can be charged when the car is parked, which reduces the amount of other electric energy used by the car; in addition, foldable and retractable solar panels can be installed inside and outside the windows and external walls of the family, which can According to the needs of indoor lighting, adjust the folding and unfolding of the foldable retractable solar panel to supply power to some household electrical equipment; due to the use of foldable retractable solar panel, it is easy to carry, and can be used in areas without power in the wild. Electric equipment is used for power supply.
