Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, specifically to a photovoltaic panel structure that is easy to fold. Background Technology

[0002] Photovoltaics, or photovoltaic power generation, is a technology that uses the photovoltaic effect of semiconductor materials to directly convert sunlight into electrical energy. Key components involved in this process include photovoltaic panels, controllers, and inverters, primarily composed of electronic components. When photons strike the photovoltaic panel, electrons within the cell absorb sufficient energy to generate an electric current. Currently, most photovoltaic panels are integrated and fixed in place, typically installed outdoors. They cannot be extended or folded as needed, making them inconvenient to retrieve and transport during inclement weather. Prolonged exposure to wind and rain can lead to impurities remaining on the panel surface, affecting the power generation rate and ultimately shortening the panel's lifespan.

[0003] Based on this, a photovoltaic panel structure that is easy to fold is now provided, which can eliminate the drawbacks of existing technical solutions. Utility Model Content

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] Example 1 In this embodiment, as Figure 1 - Figure 6As shown, the easily foldable photovoltaic panel structure includes a first main board 101 and a second main board 102. The bottom of the first main board 101 and the second main board 102 can be equipped with mounting brackets (shown in the figure) for connection with other supporting structures, providing fixation and support, and facilitating angle adjustment. A main photovoltaic panel 103 is mounted on the top of both the first main board 101 and the second main board 102. Sliding grooves 104 are symmetrically formed inside both the first main board 101 and the second main board 102, with a secondary panel 105 slidingly disposed inside the grooves 104. A secondary photovoltaic panel 106 is mounted on the top of the secondary panel 105. The shape can be adjusted according to usage requirements, flexibly adapting to different installation areas in areas with limited space, such as rooftops, reducing installation difficulty. The core of both the main photovoltaic panel 103 and the secondary photovoltaic panel 106 is a semiconductor material. The power generation principle is: when sunlight shines on the semiconductor, photons transfer their energy to electrons within the semiconductor, allowing the electrons to gain enough energy to break free from the atoms and become free electrons. An internal electric field (PN junction) is pre-formed inside the solar cell through a doping process, and this electric field forces the free electrons to... Electrons move towards the N-type region (negative electrode), and holes move towards the P-type region (positive electrode), thus forming positive and negative electrodes on the upper and lower surfaces of the solar cell. When the two electrodes are connected into a circuit by wires, free electrons move directionally under the influence of the electric field, thereby generating direct current. The voltage and current generated by a single photovoltaic cell are very small, so multiple cells need to be connected in series to increase the voltage, and these series-connected cells are then connected in parallel to increase the current. The cells are welded together by metal wires (grid lines) and encapsulated in glass, EVA film, and a backsheet. Between them, a complete photovoltaic panel is formed, namely the main photovoltaic panel 103 and the auxiliary photovoltaic panel 106. Two live cables (positive + and negative -) are provided on one side of the photovoltaic panel. The cables are connected to the junction box at the bottom of the photovoltaic panel. The connecting cable of the auxiliary photovoltaic panel 106 is a flexible wire with a waterproof connector and is reserved with sufficient length so that the wire will not be broken when the auxiliary panel 105 is extended, expanded and folded. The flexible wire extends to the outside of the slide 104 and the end finally converges into the junction box. The power generation principle and electrical connection method are existing technologies and will not be described further here. The first main board 101 and the second main board 102 are movably connected by a folding component 200, so that the first main board 101 and the second main board 102 can be folded and stacked together, thereby reducing the area occupied and making it easy to store and carry. The first main board 101 is also provided with an adjustment component 300 for adjusting the extension of the sub-board 105 to the outside of the first main board 101, which makes it easier to extend the overall structural length, increase the overall area of ​​the photovoltaic panel, and thus generate more current. The folding assembly 200 includes symmetrically arranged connecting plates 201. The two ends of the connecting plates 201 are rotatably connected to the first main board 101 and the second main board 102, respectively, so that the first main board 101 and the second main board 102 can be folded and stacked together smoothly. A handle 202 is fixedly provided on one side of the first main board 101, and a pull handle 203 is fixedly provided on one side of the second main board 102. A slot 204 is provided on the upper surface of the handle 202. A locking block 205 that matches the slot 204 is slidably provided inside the pull handle 203. The end of the locking block 205 is connected to the pull handle 203 by a spring. A circular groove (shown in the figure) is provided on the surface of both the slot 204 and the locking block 205. The positions of the slot 204 and the locking block 205 can be fixed by bolts or pins, etc., which facilitates operation and reduces the difficulty of use for personnel. Among them, such as Figure 3 - Figure 6 As shown, the adjustment assembly 300 includes a gear groove 301 disposed inside the first main board 101. A first bevel gear 302 is rotatably disposed inside the gear groove 301. A second bevel gear 303 is meshed on one side of the first bevel gear 302. The gear shaft of the second bevel gear 302 is rotatably connected to the first main board 101 via a bearing to reduce frictional resistance. One end of the gear shaft of the second bevel gear 303 extends to the outside of the first main board 101 and is fixedly connected to a throttle 304. The first bevel gear 302 is fixedly mounted on a bidirectional lead screw 305. The threads at both ends of the 05 are opposite in direction and are adapted to the threaded holes inside the sub-plate 105. The two ends of the bidirectional lead screw 305 extend into the slide groove 104 and are threadedly connected to the corresponding sub-plate 105. The bidirectional lead screw 305 is rotatably connected to the first main plate 101. When the user turns the handle 304, the second bevel gear 303 can be rotated, thereby driving the first bevel gear 302 and the bidirectional lead screw 305 to rotate. The two sub-plates 105 move closer or further away from each other along the direction of the slide groove 104, thereby achieving the effect of storing or extending the sub-plate 105. Among them, such as Figure 1 - Figure 6 As shown, a limiting plate 107 is fixedly provided at the end of the sub-plate 105. The height of the limiting plate 107 is greater than the height of the slide groove 104, which can prevent the sub-plate 105 from completely sliding out of the slide groove and avoid structural detachment. An extension block 108 is fixedly provided on the side of the limiting plate 107 away from the folding assembly 200. Mounting blocks 109 are symmetrically provided on the surface of the first main plate 101. The extension block 108 and the mounting block 109 are connected by a telescopic rod 110 to increase structural stability. The telescopic rod 110 can be limited by several bolts to reduce the bending deformation of the sub-plate 105 caused by wind or its own weight. Among them, such as Figure 1 and Figure 5 As shown, the second motherboard 102 has the same specifications, size and structure as the first motherboard 101, and the second motherboard 102 also has an adjustment component 300 inside; Among them, such as Figure 3 As shown, the surfaces of the first main board 101 and the second main board 102 are evenly distributed with a number of round holes. A pin is installed on the throttle 304. One end of the pin is inserted into any of the round holes to fix the position of the throttle 304 and the second bevel gear 303, thereby fixing the position of the first bevel gear 302 and the two side plates 105, preventing the side plates 105 from sliding due to their own weight or external force during use, and ensuring structural stability. Among them, such as Figure 1 and Figure 2 As shown, both handle 202 and pull handle 203 are U-shaped; Among them, such as Figure 4 As shown, the first bevel gear 302 and the second bevel gear 303 are matched in size to avoid the parts getting stuck. The lower surfaces of the first main board 101 and the second main board 102 can also be provided with inspection slots to facilitate the inspection and lubrication of internal parts. Example 2 The difference from Example 1 is that, as in Example 2, ... Figure 6 As shown, rubber pads are provided at the corresponding positions of the slide groove 104 and the sub-photovoltaic panel 106. That is, rubber pads are provided at the opening of the slide groove 104 and the corresponding positions of the sub-photovoltaic panel 106. The rubber pads are bonded or embedded in the slide groove 104. The rubber pads can buffer the impact of the sub-photovoltaic panel 106 when it expands and contracts, protect the edges of the sub-photovoltaic panel 106 from damage due to friction, and fill the gap between the slide groove 104 and the sub-panel 105 to prevent rainwater and dust from entering the interior of the slide groove 104 and extend the service life of the structure. When using the photovoltaic panels, if it is necessary to store or transport them, the user pulls the handle 202 of the first main board 101 or the handle 203 of the second main board 102 to make the corresponding main board rotate around the rotation axis of the connecting plate 201, so that the first main board 101 and the second main board 102 are stacked. Then, the user presses the locking block 205 inside the handle 203 to make the locking block 205 embed into the locking groove 204 of the handle 202. The two main boards are then rigidly locked by bolts or pins, etc., reducing the space occupied. When the photovoltaic panel is needed, the bolts or pins are removed, and the locking block 205 inside the handle 203 returns to its initial state under the action of the spring force, so that the locking block 205 disengages from the slot 204, releasing the lock between the two main boards. Then, the second main board 102 is rotated to one side, so that the two main boards are in an unfolded state, thereby putting the main photovoltaic panel 103 into a ready-to-use state. The height and angle of the main photovoltaic panel 103 can be adjusted using the mounting bracket. If it is necessary to increase the total power generation, the area of ​​the auxiliary photovoltaic panel 106 can be expanded using the adjustment component 300.

[0023] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
