Description

Technical Field

[0001] This invention relates to the field of solar panel technology, and in particular to a latch-type folding solar panel. Background Technology

[0002] Solar panels, also known as photovoltaic panels, are used in photovoltaic power generation systems, covering residential electricity, communication equipment, building-integrated photovoltaics (BIPV), and aerospace. A solar panel typically consists of a single sheet within a frame, followed by a power output line. When used with outdoor electrical equipment (such as streetlights, cameras, etc.), a support frame is usually installed on the back of the frame. This frame is primarily for mounting the solar panel around the equipment and providing a better installation angle.

[0003] However, existing solar panels still have the following problems:

[0004] ① Solar panels are a single, integrated panel. Large panels require more space for transportation and storage, resulting in higher transportation costs.

[0005] ② The solar panel and the bracket should be either integrated or separate. If integrated, the space occupied will be larger, which will increase the transportation cost. If separate, although it can be packaged separately to save transportation costs, how to set up a convenient assembly structure will be a problem to be solved.

[0006] Therefore, it is necessary to optimize the structure of existing solar panels. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the purpose of this invention is to provide a solar panel that is easy to assemble with a pin and can be folded.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A folding solar panel with a latch includes a first panel, a second panel, and a support frame. Photovoltaic panels are installed on the surfaces of both the first and second panels. The first and second panels are connected on one side by a hinge, allowing them to be folded together or unfolded. A latch seat is provided on the back of both the first and second panels at adjacent edges. The latch seat has an insertion cavity, and a limiting edge is provided at the top of the insertion cavity. A locking block is provided at the top of the support frame.

[0010] When the first plate and the second plate are unfolded, the pin seats on the first plate and the second plate are joined together to make the insertion cavity interconnected to form a pin cavity that can satisfy the insertion of the insertion block. The insertion block is inserted into the pin cavity from below and forms a top contact with the limiting edge.

[0011] Preferably, the insert block has a clearance opening, and a suspended snap fastener is connected inside the clearance opening. The front end of the snap fastener protrudes from the surface of the insert block, and a toggle block is provided at the rear end of the snap fastener. Pressing the toggle block can cause the front end of the snap fastener to retract into the clearance opening. A locking slot is provided at the corresponding position of the pin cavity relative to the snap fastener. When the insert block is inserted into the pin cavity, the snap fastener is embedded in the locking slot.

[0012] Preferably, a pad is provided below the first plate and the second plate relative to the photovoltaic panel, and the pads of the first plate and the second plate are connected by a flexible connecting piece, which covers the fold of the first plate and the second plate.

[0013] Preferably, the pad and the flexible connecting piece fill the entire inner cavity bottom of the first plate and the second plate, and both the pad and the flexible connecting piece are waterproof materials.

[0014] Preferably, a power cord is provided at one of the plug sockets, the power cord extends into the interior of the first plate or the second plate and connects to the positive and negative terminals of the photovoltaic panel, and both sides of the plug block are provided with extension edges, the extension edges and the sidewalls of the plug block forming a winding portion for the power cord to be wound.

[0015] Preferably, the power cord is provided with a plug at one end, and the extended side is provided with a C-shaped opening for clamping the cord.

[0016] By adopting the above-mentioned solution, the present invention features a design in which the first plate and the second plate can be folded together, allowing the original monolithic structure to be folded, effectively reducing storage volume and transportation costs. At the same time, the combination of the pin-type connector and the support frame allows for very convenient assembly. Furthermore, the insertion structure is set at the folding point, so that after assembly with the support frame, the unfolded state between the first plate and the second plate can be locked, achieving a dual function.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection. They can refer to a direct connection or an indirect connection through an intermediate medium, and they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0025] like Figures 1 to 5As shown, this embodiment provides a pin-mounted folding solar panel, including a first panel 1, a second panel 2, and a support frame 3. Photovoltaic panels 4 are installed on the surfaces of both the first panel 1 and the second panel 2. One side of the first panel 1 and the second panel 2 is connected by a hinge 5, allowing the first panel 1 and the second panel 2 to be folded together or unfolded. Pin seats 6 are provided on the back of the first panel 1 and the second panel 2 at adjacent edges. The pin seats 6 are provided with insertion cavities 7. The top of the insertion cavity 7 is provided with a limiting edge 8. The top of the support frame 3 is provided with a mating block 9.

[0026] When the first plate 1 and the second plate 2 are unfolded, the pin seats 6 on the first plate 1 and the second plate 2 are aligned and merged to make the insertion cavity 7 interconnected to form a pin cavity 10 that can satisfy the insertion of the insertion block 9. The insertion block 9 is inserted into the pin cavity 10 from below and forms a top contact with the limiting edge 8.

[0027] This embodiment features a foldable design for the first plate 1 and the second plate 2, dividing the originally monolithic structure into two foldable pieces, effectively reducing storage volume and transportation costs. Furthermore, the combination of a pin-type connector with the support frame 3 allows for convenient assembly. During assembly, simply keep the first plate 1 and the second plate 2 in their unfolded state, then insert the insert block 9 from the bottom into the pin cavity 10 until the top of the insert block 9 touches the limiting edge 8. This assembly design not only facilitates assembly but also, by placing the insert at the fold, after assembly with the support frame 3, places both ends of the insert block 9 into the insertion cavities 7 of the first plate 1 and the second plate 2 respectively, thus locking the unfolded state of the first plate 1 and the second plate 2, achieving a dual function.

[0028] Furthermore, to enhance the stability after installation, the insert block 9 in this embodiment is provided with a clearance opening 11. A suspended snap 12 is connected inside the clearance opening 11. The front end of the snap 12 protrudes from the surface of the insert block 9, and a toggle block 13 is provided at the rear end of the snap 12. Pressing the toggle block 13 can cause the front end of the snap 12 to retract into the clearance opening 11. A locking slot 14 is provided at the corresponding position of the pin cavity 10 relative to the snap 12. When the insert block 9 is inserted into the pin cavity 10, the snap 12 is embedded in the locking slot 14, thus completing the locking and preventing the insert block 9 from being pulled out. When unlocking is required, simply press the toggle block 13 with your finger to deform the snap 12, thereby disengaging the top of the snap 12 from the locking slot 14 and unlocking the device.

[0029] Furthermore, since there will be a gap between the first plate 1 and the second plate 2 after folding, in order to prevent the gap and debris from falling into the first plate 1 and the second plate 2, a pad 15 is provided on the first plate 1 and the second plate 2 below the photovoltaic panel 4 in this embodiment. The pads 15 of the first plate 1 and the second plate 2 are connected by a flexible connecting piece 16. The flexible connecting piece 16 covers the folded part of the first plate 1 and the second plate 2, which is both aesthetically pleasing and can also serve as a shield.

[0030] Furthermore, since it is for outdoor use, in order to improve waterproofing, while providing a shield, the pad 15 and the flexible connecting piece 16 fill the entire inner cavity bottom of the first plate 1 and the second plate 2, and both the pad 15 and the flexible connecting piece 16 are waterproof materials, so that they can play a very good waterproofing role.

[0031] Furthermore, since the solar panel inevitably requires a power cord 17 to connect to external devices, this embodiment places the power cord 17 at one of the plug sockets 6 for convenient storage. The power cord 17 then extends into the first plate body 1 or the second plate body 2 and connects to the positive and negative terminals of the photovoltaic panel 4. Both sides of the plug block 9 are provided with extension edges 18, which, together with the sidewalls of the plug block 9, form a winding section for the power cord 17. This satisfies the need to store the power cord 17 whether it is too long or not. In addition, to prevent the power cord 17 from detaching after it has been wound, the end of the power cord 17 in this embodiment is provided with a plug head 19, and the edge of the extension edge 18 is provided with a C-shaped opening 20 for securing the cord. Thus, when necessary, the power cord 17 at the plug head 19 can be inserted into the C-shaped opening 20, and the diameter of the plug head 19 is larger than the C-shaped opening 20 to prevent detachment.

[0032] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
