Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module technology, and more specifically, it relates to a photovoltaic module that is easy to fold. Background Technology

[0002] Photovoltaic modules, commonly known as solar panels, are core power generation units made by connecting multiple solar cells in series and parallel and protecting them through lamination and encapsulation. Their function is to directly convert sunlight into direct current (DC) electricity using the photovoltaic effect of semiconductor materials. They are the most basic and widely used form of solar energy utilization that constitutes a photovoltaic power generation system.

[0003] When using existing outdoor photovoltaic modules, first place the folded photovoltaic module stably in the target location, unfold its photovoltaic panel and lock the unfolding mechanism, adjust the orientation of the photovoltaic module to maximize the reception of sunlight, and finally connect the module's output cable to the energy storage device or electrical load, and it can be put into use.

[0004] However, in the current technology, when using photovoltaic modules, users need to manually flip and unfold the multi-layered photovoltaic panels one by one. During this process, the hinge mechanism must be precisely aligned, and the panel angle must be repeatedly adjusted to ensure that it is completely flat. When recycling, the same steps must be repeated in reverse: first, release the mechanical locks, then fold the panels one by one in the folding order, and then re-tie the transport straps. This unfolding and recycling process is not only cumbersome, but also time-consuming and labor-intensive, and has poor practicality. Utility Model Content

[0005] In view of the problems in related technologies, which require flipping and unfolding multiple layers of stacked photovoltaic panels one by one, and then repeating the same steps in reverse when recycling, which is not only cumbersome, time-consuming and labor-intensive, but also has poor practicality, this utility model proposes a photovoltaic module that is easy to fold, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a photovoltaic module that is easy to fold, including a support frame, a photovoltaic folding mechanism is provided on both sides of the support frame, a scissor telescopic mechanism is provided on one side of the photovoltaic folding mechanism, an elastic opening and closing mechanism is provided at the driving end of the scissor telescopic mechanism, and an angle support mechanism is provided at the bottom of the support frame.

[0008] The opening and closing end of the elastic opening and closing mechanism drives the scissor telescopic mechanism to extend and retract, so that the telescopic end of the scissor telescopic mechanism drives the photovoltaic folding mechanism to extend and retract synchronously, so that the photovoltaic folding mechanism unfolds or folds on both sides of the support frame.

[0009] Furthermore, the photovoltaic folding mechanism includes several connecting frames, each of which is rotatably connected to both sides of the support frame. Several photovoltaic panels are embedded inside each of the connecting frames, and several first stabilizing frames and several second stabilizing frames are rotatably connected to one end of each connecting frame.

[0010] Furthermore, the scissor telescopic mechanism includes a plurality of scissor telescopic rods, which are arranged in an array, and one end of each scissor telescopic rod is rotatably connected to another scissor telescopic rod. The plurality of scissor telescopic rods are rotatably connected to each other, and a plurality of connecting shafts are rotatably connected at the rotatable joints of the plurality of scissor telescopic rods.

[0011] Furthermore, a top plate is slidably connected inside the connecting shaft, and a spring is fixedly connected to one end of the top plate. One end of the spring is fixedly connected inside the connecting shaft, and one end of the top plate contacts the surface of the first stabilizing frame.

[0012] Furthermore, a limiting groove is provided on one side of the second stabilizing frame, and several guide rods are rotatably connected at the connection between the scissor telescopic rod and another scissor telescopic rod, and the guide rods are slidably connected in the limiting groove.

[0013] Furthermore, the elastic opening and closing mechanism includes a limiting rod, which is fixedly connected inside the support frame. A sliding groove is provided on one side of the support frame, and a pressing rod is slidably connected in the sliding groove. The pressing rod is rotatably connected inside the scissor telescopic rod and slidably connected to the surface of the limiting rod. A second spring is sleeved on the surface of the limiting rod, with one end of the second spring fixedly connected to the surface of the pressing rod and the other end of the second spring fixedly connected inside the support frame.

[0014] Furthermore, the angle support mechanism includes a base plate, which is rotatably connected to one end of the support frame. A support rod is rotatably connected to the surface of the base plate, and an adjusting rod is slidably connected inside the support rod. An adjusting bolt is threaded onto the surface of the support rod. Several fixing holes are provided on one side of the support frame, and one end of the adjusting rod is engaged in the fixing holes. A limit hole is provided on the surface of the base plate, and one end of the pressing rod is engaged in the limit hole. An anti-slip pad is fixedly connected to the surface of the pressing rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses the opening and closing end of the elastic opening and closing mechanism to drive the scissor telescopic mechanism to extend and retract, so that the telescopic end of the scissor telescopic mechanism drives the photovoltaic folding mechanism to extend and retract synchronously, allowing the photovoltaic folding mechanism to unfold or fold on both sides of the support frame. This design eliminates the cumbersome process of manually flipping or retrieving the panels layer by layer, precisely aligning the hinges, and repeatedly adjusting the angle to lay them flat in traditional operations. It solves the pain points of redundant steps, time-consuming and labor-intensive processes and poor practicality of existing technologies, and realizes one-click rapid deployment and retrieval.

[0017] 2. In this utility model, after the base plate rotates around the support frame and touches the ground, the support rod is flipped over and the adjusting bolt is loosened. By pulling the adjusting rod to extend and retract within the support rod, its end is engaged with different positioning points of the fixing hole. Tightening the adjusting bolt to secure the adjusting rod completes the tilt angle locking. By switching the engagement position of the adjusting rod and the fixing hole, the tilt angle of the support frame can be changed, driving the photovoltaic panel to match the changes in the solar altitude angle and maximizing the light energy capture efficiency.

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-6 As shown, this utility model is a photovoltaic module that is easy to fold, including a support frame 1, a photovoltaic folding mechanism 2 is provided on both sides of the support frame 1, a scissor telescopic mechanism 3 is provided on one side of the photovoltaic folding mechanism 2, an elastic opening and closing mechanism 4 is provided at the driving end of the scissor telescopic mechanism 3, and an angle support mechanism 5 is provided at the bottom of the support frame 1.

[0031] The scissor telescopic mechanism 3 is driven to extend and retract by the opening and closing end of the elastic opening and closing mechanism 4, so that the telescopic end of the scissor telescopic mechanism 3 drives the photovoltaic folding mechanism 2 to extend and retract synchronously, so that the photovoltaic folding mechanism 2 can be unfolded or folded on both sides of the support frame 1.

[0032] By opening the angle support mechanism 5 and simultaneously opening the elastic opening and closing mechanism 4, the opening and closing end of the elastic opening and closing mechanism 4 drives the scissor telescopic mechanism 3 to extend and retract, so that the telescopic end of the scissor telescopic mechanism 3 drives the photovoltaic folding mechanism 2 to extend and retract synchronously, causing the photovoltaic folding mechanism 2 to unfold on both sides of the support frame 1. Then, the angle support mechanism 5 adjusts the angle of the support frame 1. When folding, the elastic opening and closing mechanism 4 is closed, and the opening and closing end of the elastic opening and closing mechanism 4 drives the scissor telescopic mechanism 3 to extend and retract, so that the telescopic end of the scissor telescopic mechanism 3 drives the photovoltaic folding mechanism 2 to extend and retract synchronously, causing the photovoltaic folding mechanism 2 to fold on both sides of the support frame 1. Then, the angle support mechanism 5 is reset, and the angle support mechanism 5 is opened to fix the elastic opening and closing mechanism 4, completing the folding process.

[0033] The scissor telescopic mechanism 3 is driven to extend and retract by the opening and closing end of the elastic opening and closing mechanism 4, so that the telescopic end of the scissor telescopic mechanism 3 drives the photovoltaic folding mechanism 2 to extend and retract synchronously, so that the photovoltaic folding mechanism 2 can be unfolded or folded on both sides of the support frame 1. This design completely eliminates the cumbersome process of manually flipping or retrieving the panels layer by layer, accurately aligning the hinges, and repeatedly adjusting the angle to lay them flat in the traditional operation. It solves the pain points of redundant steps, time-consuming and labor-intensive and poor practicality of the existing technology, and realizes one-click rapid deployment and retrieval.

[0034] In one embodiment, the photovoltaic folding mechanism 2 includes a plurality of connecting frames 201, which are rotatably connected to both sides of the support frame 1. A plurality of photovoltaic panels 202 are embedded inside the plurality of connecting frames 201, and a plurality of first stabilizing frames 203 and a plurality of second stabilizing frames 204 are rotatably connected to one end of the plurality of connecting frames 201.

[0035] By connecting the connecting frame 201 in series with a number of first stabilizing frames 203 and a number of second stabilizing frames 204, the connecting frame 201 can drive a number of photovoltaic panels 202 to flip and fold along the first stabilizing frames 203 and a number of second stabilizing frames 204.

[0036] The working principle of photovoltaic panel 202 is based on the photovoltaic effect of semiconductor materials. When sunlight shines on the PN junction made of semiconductor materials such as silicon, the photon energy is absorbed and excited electrons to jump to the conduction band, forming free electrons and holes. The built-in electric field of the PN junction then drives the electrons to move to the N-type region and the holes to move to the P-type region, forming a potential difference. If the positive and negative terminals of the battery are connected through an external circuit, the directional flow of charge generates a direct current, realizing the direct conversion of light energy into electrical energy.

[0037] In one embodiment, the scissor telescopic mechanism 3 includes a plurality of scissor telescopic rods 301 arranged in an array, with one end of each scissor telescopic rod 301 rotatably connected to another scissor telescopic rod 301. The scissor telescopic rods 301 are rotatably connected to each other. A plurality of connecting shafts 302 are rotatably connected at the rotatable connections of the scissor telescopic rods 301. A top plate 305 is slidably connected inside the connecting shaft 302. A spring 306 is fixedly connected to one end of the top plate 305, and one end of the spring 306 is fixedly connected inside the connecting shaft 302. One end of the top plate 305 contacts the surface of the first stabilizing frame 203. A limiting groove 303 is provided on one side of the second stabilizing frame 204. A plurality of guide rods 304 are rotatably connected at the connection points between the scissor telescopic rods 301 and another scissor telescopic rod 301, and the guide rods 304 are slidably connected within the limiting grooves 303.

[0038] By squeezing the scissor telescopic rods 301 outward, several scissor telescopic rods 301 are flipped along the guide rods 304, causing the scissor telescopic rods 301 to unfold on both sides. At the same time, the guide rods 304 at one end of several scissor telescopic rods 301 slide in the limiting grooves 303, causing the limiting grooves 303 to drive the second stabilizing frame 204 to move. The second stabilizing frame 204 then drives the connecting frame 201 and the first stabilizing frame 203 to unfold on both sides of the support frame 1, thereby causing the photovoltaic panel 202 to unfold. When retracting, squeezing the scissor telescopic rods 301 inward causes the scissor telescopic rods 301 to drive the guide rods 304 to move, causing the second stabilizing frame 204 to fold the connecting frame 201 and the first stabilizing frame 203 on both sides of the support frame 1. The spring 306 drives the top plate 305 to slide inside the connecting shaft 302. At the same time, one end of the top plate 305 contacts the first stabilizing frame 203, limiting the first stabilizing frame 203 and preventing it from folding to the other side.

[0039] In one embodiment, the elastic opening and closing mechanism 4 includes a limiting rod 401, which is fixedly connected inside the support frame 1. A sliding groove 402 is provided on one side of the support frame 1. A pressing rod 403 is slidably connected in the sliding groove 402. The pressing rod 403 is rotatably connected inside the scissor telescopic rod 301. The pressing rod 403 is slidably connected to the surface of the limiting rod 401. A second spring 404 is sleeved on the surface of the limiting rod 401. One end of the second spring 404 is fixedly connected to the surface of the pressing rod 403, and the other end of the second spring 404 is fixedly connected inside the support frame 1.

[0040] Spring 404 drives the pressing rod 403 to slide on the surface of the limiting rod 401. Simultaneously, the pressing rod 403 slides in the sliding groove 402, causing the pressing rod 403 to drive one end of the scissor telescopic rod 301 to move inside the support frame 1. This causes the scissor telescopic rod 301 to flip along the guide rod 304, unfolding both sides of several scissor telescopic rods 301. During retraction, the pressing rod 403 moves outward, causing the pressing rod 403 to drive the scissor telescopic rod 301 to move. At the same time, the pressing rod 403 compresses the spring 404, causing the scissor telescopic rod 301 to drive the guide rod 304 to move, folding the second stabilizing frame 204, the connecting frame 201, and the first stabilizing frame 203 on both sides of the support frame 1.

[0041] In one embodiment, the angle support mechanism 5 includes a base plate 501, which is rotatably connected to one end of the support frame 1. A support rod 502 is rotatably connected to the surface of the base plate 501. An adjusting rod 503 is slidably connected inside the support rod 502. An adjusting bolt 504 is threadedly connected to the surface of the support rod 502. A plurality of fixing holes 505 are opened on one side of the support frame 1. One end of the adjusting rod 503 is engaged in the fixing hole 505. A limiting hole 506 is opened on the surface of the base plate 501. One end of the pressing rod 403 is engaged in the limiting hole 506. An anti-slip pad 507 is fixedly connected to the surface of the pressing rod 403.

[0042] By rotating one end of the base plate 501 along one end of the support frame 1, the base plate 501 contacts the ground. The support rod 502 is flipped over, the adjusting bolt 504 is loosened, and the adjusting rod 503 moves inside the support rod 502. The adjusting bolt 504 is rotated so that one end of the adjusting bolt 504 presses against the surface of the adjusting rod 503, causing one end of the adjusting rod 503 to engage in the fixing hole 505, thus supporting the support frame 1. By engaging different fixing holes 505 with the adjusting rod 503, the angle of the support frame 1 can be adjusted, thereby allowing the photovoltaic panel 202 to be angled. When retrieving the photovoltaic panel 202, the pressing rod 403 is moved outwards, causing the pressing rod 40... 3. The scissor telescopic rod 301 moves, while the pressing rod 403 compresses the second spring 404, retracting the adjusting rod 503 into the support rod 502. By resetting the base plate 501, the limiting hole 506 on the surface of the base plate 501 engages with one end of the pressing rod 403, fixing the pressing rod 403. At the same time, the anti-slip pad 507 prevents the pressing rod 403 from sliding out of the limiting hole 506. When the photovoltaic panel 202 needs to be opened, the base plate 501 is flipped directly, causing the base plate 501 to disengage from the limiting hole 506. This allows the second spring 404 to drive the pressing rod 403 to slide on the surface of the limiting rod 401, thereby automatically opening the photovoltaic panel 202.

[0043] Through the above technical solution, 1. By flipping the base plate 501, the base plate 501 is disengaged from the limiting hole 506, thereby causing the spring 404 to drive the pressing rod 403 to slide on the surface of the limiting rod 401. Simultaneously, the pressing rod 403 slides in the sliding groove 402, causing the pressing rod 403 to drive one end of the scissor telescopic rod 301 to move inside the support frame 1, causing the scissor telescopic rod 301 to flip along the guide rod 304, causing several scissor telescopic rods 301 to unfold on both sides. At the same time, the guide rod 304 at one end of several scissor telescopic rods 301 slides in the limiting groove 303, causing the limiting groove 303 to drive the second stabilizing frame 204 to move, causing the second stabilizing frame 204 to move. The connecting frame 201 and the first stabilizing frame 203 unfold on both sides of the support frame 1, thereby driving the photovoltaic panel 202 to unfold automatically. During retraction, the pressing rod 403 moves outward, causing the pressing rod 403 to drive the scissor telescopic rod 301 to move. At the same time, the pressing rod 403 compresses the second spring 404, causing the scissor telescopic rod 301 to drive the guide rod 304 to move, folding the second stabilizing frame 204, the connecting frame 201, and the first stabilizing frame 203 on both sides of the support frame 1. The bottom plate 501 is reset, and the limiting hole 506 on the surface of the bottom plate 501 engages with one end of the pressing rod 403, fixing the pressing rod 403. The unfolding and folding of the photovoltaic panel 202 are completed.

[0044] 2. By rotating one end of the base plate 501 along one end of the support frame 1, the base plate 501 contacts the ground. The support rod 502 is flipped over, the adjusting bolt 504 is loosened, and the adjusting rod 503 is moved inside the support rod 502. The adjusting bolt 504 is rotated so that one end of the adjusting bolt 504 presses against the surface of the adjusting rod 503, so that one end of the adjusting rod 503 is engaged in the fixing hole 505, thus supporting the support frame 1. By engaging the adjusting rod 503 in different fixing holes 505, the angle of the support frame 1 can be adjusted, thereby allowing the photovoltaic panel 202 to adjust its angle according to the sunlight.
