Description

Technical Field

[0001] This application relates to the field of solar energy technology, and more particularly, to a photovoltaic module. Background Art

[0002] A solar panel is a device that absorbs sunlight and directly or indirectly converts solar radiant energy into electrical energy through the photovoltaic effect or the photochemical effect. Compared with ordinary batteries and rechargeable batteries, solar cells are greener products that are more energy-saving and environmentally friendly.

[0003] In order to facilitate storage, in the related art, the solar panel is usually divided into multiple flat plates and connected with a flexible material, so that the multiple flat plates can be folded.

[0004] However, in actual use, the structure of the solar panel is relatively loose during the folding process, and it is easy to spread out, which is inconvenient to carry and seriously affects the user experience. Summary of the Utility Model

[0005] This application aims to solve at least one of the technical problems existing in the related art.

[0006] To this end, this application provides a photovoltaic module, including: a power generation unit; at least two frames, respectively disposed on both sides of the power generation unit in a first direction and foldably cooperating with the power generation unit; wherein, at least two connecting parts are provided on the frames; when the photovoltaic module is in a folded state, at least two frames are located on the outermost surface of the power generation unit; and the connecting parts of at least two frames are aligned.

[0007] In the above technical solution, the photovoltaic module can be folded when not in use to reduce the volume. After folding, the two frames are respectively located on the two outer surfaces of the power generation unit to provide protection for the power generation unit in the folded state; at this time, the connecting parts are aligned with each other, so that the folded photovoltaic module forms a stable structure, so that the photovoltaic module will not easily spread out in the folded state, and the overall stability is good, which is convenient to carry and helps to improve the user experience.

[0008] In some technical solutions, optionally, the photovoltaic module further includes a locking structure, and the locking structure is magnetic or snap-type; when the photovoltaic module is in a folded state, the locking structure is configured to connect the aligned connecting parts to each other. The magnetic locking structure attracts each other through magnetic force. After the photovoltaic module is folded, the magnetic attraction will automatically connect the connecting parts together without additional operations or tools, which is convenient and fast. The snap-type locking structure is not prone to failure and has high durability.

[0009] In some technical solutions, optionally, a handle opening is provided on the connecting portion. In this way, after folding, a comfortable gripping point can be provided for the user, enabling the user to easily lift the folded photovoltaic module, thus facilitating portability.

[0010] In some technical solutions, optionally, the photovoltaic module further includes a first bundling strap disposed on a side of the frame away from the connecting portion; one end of the first bundling strap is fixedly connected to one of the two frames, and the other end is interconnected with the other of the two frames through a quick-release structure.

[0011] In the above technical solution, the folded photovoltaic module is further constrained by the first bundling strap, providing an additional fixing effect for the folded photovoltaic module. Together with the buckle structure of the connecting portion, it can prevent the photovoltaic module from coming apart during carrying.

[0012] In some technical solutions, optionally, the photovoltaic module further includes a second bundling strap; the second bundling strap is disposed on a side of the frame away from the connecting portion and away from the first bundling strap; one end of the second bundling strap is fixedly connected to one of the two frames, and the other end is interconnected with the other of the two frames through a quick-release structure.

[0013] In the above technical solution, by introducing the second bundling strap and disposing it on the other side of the frame, such a layout provides double fixation for the folded photovoltaic module, increasing the structural stability and safety, and thus can prevent the photovoltaic module from coming apart during carrying.

[0014] In some technical solutions, optionally, the quick-release structure includes at least one of a buckle, a snap fastener, or a Velcro. With such a design, a locked state can be quickly formed during folding, and when in use, it can also be quickly separated, with simple operation, thus improving the operation efficiency and convenience for the user.

[0015] In some technical solutions, optionally, the power generation unit includes one or more photovoltaic panels; when there are multiple photovoltaic panels, the multiple photovoltaic panels are sequentially connected in a first direction, and adjacent two photovoltaic panels can be rotated to contact each other.

[0016] In some technical solutions, optionally, the photovoltaic panel includes: a protection frame provided with an installation cavity; and a body disposed in the installation cavity. With such a design, the photovoltaic panel has sufficient structural strength and rigidity, which helps to improve the durability and safety of the photovoltaic panel.

[0017] In some technical solutions, optionally, an opening groove is provided on one side of the protection frame along the left-right direction; wherein, the power generation unit further includes a bus bar disposed in the opening groove; and a junction box disposed on the body and connected to the bus bar.

[0018] In the above technical solution, the design of connecting the photovoltaic panels through a busbar can reduce the usage of wire materials and junction boxes, save materials, and have a simple appearance. At the same time, integrating the busbar into the protection frame can protect the busbar and prevent it from being damaged.

[0019] In some technical solutions, optionally, the power generation unit further includes a cover plate disposed above the busbar to fix the busbar in the opening groove. This design can prevent the busbars from winding around each other.

[0020] In some technical solutions, optionally, the power generation unit further includes a protective pad disposed at both ends of the opening groove to protect the busbar. In this way, it can prevent the sharp parts at both ends of the opening groove from scratching the busbar.

Detailed implementation manners

[0031] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0032] In the following description, many specific details are set forth in order to fully understand the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited to the limitations of the specific embodiments disclosed below.

[0033] The following combines Figures 1 to 6 , and through specific embodiments and their application scenarios, the photovoltaic module provided by the embodiments of the present application will be described in detail.

[0034] Referring to Figures 1 to 3 , in the embodiments of the present application, a photovoltaic module is provided, and its structure includes a power generation unit 100 and a frame 200.

[0035] Referring to Figure 2 and Figure 3 , specifically, the power generation unit 100 includes a plurality of photovoltaic panels 110 connected in sequence along a first direction, and adjacent two photovoltaic panels 110 can be rotated relative to each other until they come into contact. In this way, the photovoltaic module can be folded up when not in use to reduce its volume.

[0036] There are at least two frames 200, and they are rotatably connected to both sides of the power generation unit 100 in the first direction when unfolded, so that the frame 200 and the power generation unit 100 are foldably matched. Among them, connection parts 210 are provided on at least two frames 200. After folding, at least two frames 200 are respectively located on the two outermost surfaces of the power generation unit 100 to provide protection for the power generation unit 100 in the folded state; and at this time, the connection parts 210 are aligned with each other, so that the folded photovoltaic module forms a stable structure, making the photovoltaic module not easily come apart in the folded state, with good overall stability, thus being convenient to carry and helping to improve the user experience.

[0037] In the above embodiments, after the photovoltaic module is unfolded, there is a certain angle between the multiple photovoltaic panels 110 and the working surface (i.e., they are inclined), and the frame 200 is laid flat on the working surface. Such a design can prevent the frame 200 from blocking the photovoltaic panels 110; at the same time, the multiple photovoltaic panels 110 are inclined, which can prevent sundries (such as rain, snow, dust, etc.) from accumulating on the photovoltaic panels 110, thereby helping to improve the power generation efficiency of the photovoltaic module.

[0038] It can be understood that the power generation unit 100 may also include only one photovoltaic panel 110.

[0039] In some embodiments, the frame 200 and the power generation unit 100 are rotatably connected through a hinge. It can be understood that the frame 200 and the power generation unit 100 can also be rotatably connected through structures such as a rotating shaft, and this embodiment is not limited thereto.

[0040] In some embodiments, the photovoltaic module further includes a locking structure 500, and the locking structure 500 is magnetic or snap-type; when the photovoltaic module is in the folded state, the locking structure 500 is configured to connect the aligned connecting portions 210 to each other. In this way, a stable structure can be formed for the folded photovoltaic module; at the same time, by connecting through the locking structure 500, when it needs to be unfolded, unlocking can be completed with a simple operation, which is convenient and fast.

[0041] In the above embodiments, the magnetic snap locks attract each other by magnetic force. After the photovoltaic module is folded, the magnetic attraction force will automatically connect the connecting portions 210 together without additional operations or tools, which is convenient and fast. The snap-type lock is not prone to failure and has high durability.

[0042] In some embodiments, a handle opening 211 is provided on the connecting portion 210. In this way, after folding, a comfortable gripping point can be provided for the user, enabling the user to easily lift the folded photovoltaic module, thus facilitating portability. It can be understood that in actual applications, the handle opening 211 can be provided on one of the connecting portions 210; or the handle opening 211 can be provided on both of the connecting portions 210. In this way, the handle openings 211 on the two connecting portions 210 together form a gripping space 220, which is more convenient for the user to grip.

[0043] In the above embodiments, the two frames 200 are respectively rotatably connected to the power generation unit 100 on both sides in the first direction when unfolded; the connecting portion 210 is provided on the side of the frame 200 facing away from the power generation unit 100. In this way, after folding, the connecting portion 210 is located at the top of the power generation unit 100, thus facilitating the user to pick up the folded photovoltaic module.

[0044] In actual applications, the connecting portion 210 is formed by bending upward from the side of the frame 200 away from the power generation unit 100.

[0045] Among them, the photovoltaic module further includes a first binding band 300, and the first binding band 300 is arranged on the side of the frame 200 away from the connecting portion 210; one end of the first binding band 300 is fixedly connected to one of the two frames 200, and the other end bypasses the power generation unit 100 and is interconnected with the other of the two frames 200 through a quick-release structure 600.

[0046] In the above embodiment, the bottom of the folded photovoltaic module is further constrained by the first binding band 300, providing an additional fixing effect for the folded photovoltaic module. Cooperating with the buckle structure 500 of the connecting portion 210, it is possible to prevent the photovoltaic module from spreading during carrying.

[0047] In the above embodiment, the photovoltaic module further includes a second binding band 400, and the second binding band 400 is arranged on the side of the frame 200 away from the connecting portion 210 and away from the first binding band 300; one end of the second binding band 400 is fixedly connected to one of the two frames 200, and the other end bypasses the power generation unit 100 and is interconnected with the other of the two frames 200 through a quick-release structure 600.

[0048] In the above embodiment, by introducing the second binding band 400 and arranging it on the other side of the frame 200, such a layout provides double fixation for the folded photovoltaic module, increasing the structural stability and safety, thereby preventing the photovoltaic module from spreading during carrying.

[0049] In the above embodiment, the quick-release structure 600 includes at least one of a buckle, a snap fastener or a magic tape. With such a design, a locked state can be quickly formed during folding, and when in use, it can also be quickly separated, with simple operation, thereby improving the operation efficiency and convenience of the user.

[0050] Referring to Figure 4 and Figure 5 , in some embodiments, the photovoltaic panel 110 includes a protective frame 111 and a body 112. Among them, an installation cavity 113 is provided on the protective frame 111; the body 112 is arranged in the installation cavity 113, that is, the protective frame 111 is located around the body 112. With such a design, the photovoltaic panel 110 has sufficient structural strength and rigidity, which helps to improve the durability and safety of the photovoltaic panel 110.

[0051] In practical applications, the protective frames 111 of two adjacent photovoltaic panels 110 are rotatably connected through a hinge. However, it can be understood that the protective frames 111 can also be rotatably connected through structures such as a rotating shaft, and this embodiment is not limited thereto.

[0052] Referring to Figure 5 and Figure 6, in the above embodiment, an opening groove 114 is provided on one side of the protection frame 111 in the second direction. Wherein, the power generation unit 100 further includes a bus bar 120 and a junction box 130; the bus bar 120 is disposed in the opening groove 114, and the junction box 130 is disposed on the body 112 and connected to the bus bar 120. In this way, the design of connecting the photovoltaic panels 110 through a single bus bar 120 can reduce the usage of wire materials and junction boxes 130, save materials, and have a simple appearance; at the same time, integrating the bus bar 120 into the protection frame 111 can protect the bus bar 120 and prevent the bus bar 120 from being damaged.

[0053] In the above embodiment, the power generation unit 100 further includes a cover plate 140, which is disposed above the bus bar 120 to fix the bus bar 120 in the opening groove 114. This design can prevent the bus bars 120 from being entangled with each other.

[0054] In practical applications, considering that the two ends of the opening groove 114 are relatively sharp and likely to scratch the bus bar 120, in some embodiments, the power generation unit 100 further includes a protection pad 150. After the assembly is completed, the protection pad 150 can be installed at both ends of the opening groove 114 to prevent the bus bar 120 from being scratched.

[0055] Exemplarily, the protection pad 150 is a silicone pad.

[0056] From the above description, it can be seen that the photovoltaic module of the present application has the following beneficial effects:

[0057] 1. The frame 200 is located outside the power generation unit 100 to play a protective role; at the same time, when the frame 200 is closed, the handle opening 211 on the connecting part 210 together forms a holding space 220, thereby providing a comfortable holding point for the user, enabling the user to easily lift the folded photovoltaic module.

[0058] 2. The bottom of the frame 200 is provided with a binding strap to ensure that the photovoltaic module will not come apart after being stored.

[0059] 3. The design of connecting the photovoltaic panels 110 through a single bus bar 120 reduces the usage of wire materials and junction boxes 130, saves materials, and has a simple appearance.

[0060] 4. Integrating the bus bar 120 into the protection frame 111 can protect the bus bar 120 and prevent the bus bar 120 from being damaged.

[0061] 5. The protection frame 111 can also play a role in fixing the bus bar 120 and prevent the bus bars 120 from being entangled with each other.
