Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to an angle code, a frame fixing structure and a photovoltaic component. Background Art

[0002] The frame used for fixing and supporting the external structure of the photovoltaic module is called the photovoltaic frame. The connection of the photovoltaic frame needs to be fixed with angle brackets. The conventional fixing method is riveting, which requires pre-riveting points on the photovoltaic frame. When the frame is assembled, the angle bracket is squeezed into the angle bracket cavity of the frame and has an interference fit with the pre-riveted points to prevent the angle bracket from loosening.

[0003] In the market, with the advancement of photovoltaic cell technology and the reduction of costs, a variety of frame materials have emerged, including steel frames, composite frames, etc., and composite frames cannot effectively form strong inner concave and convex points based on conventional rivet points because they do not have an implanted metal skeleton for support; in addition, in order to reduce costs, the wall thickness and height of the frame are also designed to be smaller and smaller, making the frame strength lower and lower, resulting in conventional corner code and frame locking methods. The use is more difficult.

[0004] Based on the above situation, there is an urgent need for a corner code, a frame fixing structure and a photovoltaic module to solve the problems existing in the prior art. Utility Model Content

[0005] The first purpose of the utility model is to provide an angle code that can simplify the way of combining and connecting with a photovoltaic frame, thereby saving the processing cost and equipment cost of the photovoltaic frame.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] An angle code is connected to the photovoltaic frame. The angle code includes an angle code body and a fixing part. The angle code body is embedded in the angle code cavity on the photovoltaic frame. The fixing part is arranged on the angle code body. A puncture part is arranged on the fixing part on the side facing the inner wall of the angle code cavity. The puncture part can puncture and be inserted into the inner wall surface of the angle code cavity to fix the angle code body to the photovoltaic frame.

[0008] Preferably, a conical guide structure is provided at the end of the angle code body.

[0009] Preferably, a slot is provided on the angle code body, the fixing member is limitedly disposed in the slot, and the puncture portion is penetrated through an opening of the slot.

[0010] Preferably, a stopper is protruding from the side wall of the slot, and the fixing member is clamped between the stopper and the bottom wall of the slot.

[0011] Preferably, the fixing piece and the angle code body are adhesively connected with an adhesive layer.

[0012] Preferably, a portion of the angle code body connected to the adhesive layer is provided with an overflow groove.

[0014] Preferably, the puncture portion is protrudingly provided at the middle position of the fixing member; or, the puncture portion is protrudingly provided at the side position of the fixing member; or, part of the fixing member is folded upward to form the puncture portion.

[0015] The beneficial effect of the angle bracket provided by the utility model is that the angle bracket and the photovoltaic frame are fixed by the puncture part puncturing into the inner wall surface of the angle bracket cavity. In this way, not only can the angle bracket and the photovoltaic frame be stably connected, but also the pre-riveting of rivets on the photovoltaic frame made of composite materials can be avoided, which simplifies the combined connection method between the two and saves the processing cost and equipment cost of the photovoltaic frame.

[0016] The second purpose of the utility model is to provide a frame fixing structure. By setting the above-mentioned angle code in the frame fixing structure, the grouping method of the frame fixing structure can be simplified, the processing cost and equipment cost of the frame fixing structure can be saved, and the performance of use can be ensured.

[0017] To achieve this purpose, the utility model adopts the following technical solutions:

[0018] The frame fixing structure includes a plurality of photovoltaic frames and the above-mentioned corner codes, wherein the photovoltaic frames are provided with corner code cavities, the corner codes are embedded in the corner code cavities, and adjacent photovoltaic frames are fixedly connected by the corner codes.

[0019] The frame fixing structure provided by the utility model has the following beneficial effects: through the puncture part provided on the corner bracket, the corner bracket and the photovoltaic frame can be fixedly connected without pre-punching rivets on the photovoltaic frame. Compared with the prior art, the combined connection method between the corner bracket and the photovoltaic frame can be simplified, saving the processing cost and equipment cost of the frame fixing structure. Moreover, the potential safety hazard of damage and deformation caused by pre-punching rivets on the photovoltaic frame made of composite materials can be eliminated, thereby ensuring the performance of the frame fixing structure.

[0020] The third object of the present utility model is to provide a photovoltaic module, which can improve the production and assembly efficiency of the photovoltaic module and reduce the assembly cost by using the above-mentioned frame fixing structure.

[0039] The technical solution provided by the utility model is introduced below in conjunction with the accompanying drawings and specific embodiments.

[0040] Embodiment 1

[0041] Combination Figures 1 to 4As shown, this embodiment provides a corner code 20, which is applied to a photovoltaic module. The photovoltaic module includes a photovoltaic power generation panel and a frame fixing structure. The frame fixing structure includes four photovoltaic frames 10 connected end to end. Two adjacent photovoltaic frames 10 are connected by the above-mentioned corner code 20.

[0042] Specifically, refer to Figure 1 As shown, the angle code 20 includes an angle code body 21 and a fixing part 22, wherein the angle code body 21 is an L-shaped structure, and the two parts of the angle code body 21 that are perpendicular to each other are respectively embedded in the angle code cavity 11 opened on the photovoltaic frame 10; the fixing part 22 is a sheet structure and is fixedly arranged on the angle code body 21, and a puncture portion 221 is arranged on the side of the fixing part 22 facing the inner wall of the angle code cavity 11. After the angle code body 21 is embedded in the angle code cavity 11, the puncture portion 221 on the fixing part 22 can puncture and insert into the inner wall of the angle code cavity 11, so that the angle code body 21 is fixedly connected to the photovoltaic frame 10.

[0043] It is understandable that, in this embodiment, the material hardness of the puncture portion 221 needs to be greater than the material hardness of the photovoltaic frame 10, so as to ensure that the puncture portion 221 is smoothly inserted into the inner wall surface of the corner code cavity 11. It can be known that when the photovoltaic frame 10 is produced using a composite material (such as rubber, or other plastic materials such as polyurethane) to reduce the cost of the photovoltaic frame 10, other metal materials such as aluminum alloy, steel, and aluminum can be used to make the puncture portion 221, and the puncture portion 221 punctures into the inner wall of the corner code cavity 11 to achieve the fixation of the corner code 20 and the photovoltaic frame 10. In this way, not only can the corner code 20 and the photovoltaic frame 10 be stably connected, but also the pre-riveting points on the photovoltaic frame 10 made of composite materials can be avoided, which simplifies the combined connection method between the two and saves the processing cost and equipment cost of the photovoltaic frame 10.

[0044] Specifically, in this embodiment, Figure 2 As shown, a slot 211 is respectively provided on two perpendicular parts of the angle code body 21, and a fixing piece 22 is provided in each limit position in each slot 211. For the convenience of explanation, the horizontal part of the angle code 20 will be used as an example. In this part, the puncture part 221 will pass through the opening of the slot 211 and be exposed to the outside. By providing the slot 211, the main part of the fixing piece 22 can be accommodated in the angle code body 21, thereby reducing the space occupied by the entire angle code 20, so that the angle code 20 can be smoothly embedded in the angle code cavity 11.

[0045] Furthermore, a stopper 212 is protruded on one side wall of the slot 211, and the fixing member 22 is clamped between the stopper 212 and the bottom wall of the slot 211, so that the position of the fixing member 22 in the angle code body 21 is more stable, ensuring that the fixing member 22 will not loosen or shift due to external vibration or impact.

[0046] Specifically, the end of the angle code body 21 provided in this embodiment is provided with a conical guide structure 213, and the conical guide structure 213 can guide the horizontal part of the angle code body 21 to be accurately inserted into the angle code cavity 11, thereby preventing the angle code body 21 from colliding with the photovoltaic frame 10 during installation, thereby ensuring the integrity and safety of the photovoltaic frame 10.

[0047] Optionally, the angle code body 21 and the fixing member 22 provided in this embodiment are fixedly connected by a riveting process. Figure 2 As shown, after the fixing piece 22 is installed in the slot 211 in the angle code body 21, the stopper 212 on the angle code body 21 is pressed downward by using a riveting device, and a first riveting groove 2121 concave downward is formed on the upper surface of the stopper 212, and the lower surface is protruded so that the punching point of the stopper 212 abuts against the fixing piece 22, thereby achieving a fixed connection between the angle code body 21 and the fixing piece 22. The above connection method not only has high connection strength, but also improves the compactness of the entire angle code structure and greatly reduces the maintenance frequency.

[0048] Specifically, in this embodiment, combined with Figure 1 , Figure 3 and Figure 4 As shown, along the direction away from the angle code body 21 inserted into the angle code cavity 11, the puncture portion 221 is obliquely protruded on the fixing member 22, and the angle between the puncture portion 221 and the surface of the fixing member 22 is not limited in this embodiment. Through the above arrangement, the friction force between the puncture portion 221 and the inner wall of the angle code cavity 11 can be effectively reduced during the process of inserting the angle code 20 into the angle code cavity 11, thereby preventing the photovoltaic frame from being deformed during the framing process, causing the photovoltaic frame to be installed improperly or the entire photovoltaic frame to become a diamond shape after installation.

[0049] Furthermore, in the present embodiment, part of the structure of the fixing member 22 is folded upward to form the above-mentioned puncture portion 221, that is, the puncture portion 221 is connected to the fixing member 22 by an integral molding manner, which can reduce the phenomenon of fracture and breakage at the connection between the puncture portion 221 and the fixing member 22, thereby effectively enhancing the structural strength of the puncture portion 221, so that the connection stability between the angle code 20 and the photovoltaic module is guaranteed.

[0050] It should be noted that the present embodiment does not limit the position of the puncture portion 221 on the fixing member 22. For example, the puncture portion 221 may be formed protrudingly in the middle portion of the fixing member 22 (e.g. Figure 3 As shown), a puncture portion 221 may be formed on the edge of the fixing member 22 (as shown Figure 4 As shown in the figure, the two methods produce the same effect, and both methods can lock the corner code 20 with the photovoltaic frame 10. When the puncture portion 221 is provided in the middle part of the fixing member 22, the width of the puncture portion 221 can be close to the width of the fixing member 22 to enhance the bite ability of the puncture portion 221; when other parts are provided in the middle part of the fixing member 22, or in order to avoid other parts provided in the corner code cavity 11, the puncture portion 221 can be provided at the edge of the fixing member 22, so as to achieve the fixed connection between the corner code 20 and the photovoltaic frame 10, while ensuring the safety of other parts in use and preventing interference caused by the puncture portion 221.

[0051] It should also be noted that this embodiment does not limit the number of puncture portions 221 provided on the fixing member 22. As long as the angle code 20 can be stably connected to the photovoltaic module, it is within the protection scope of the present utility model. Figure 3 As shown, two puncture portions 221 are convexly arranged in front and back in the middle part of the fixing member 22; Figure 4 As shown, two puncture portions 221 arranged one behind the other are respectively provided at the two edges of the fixing member 22 .

[0052] Specifically, the outer edge of the puncture portion 221 is provided with saw teeth 2211, which can increase the contact area and friction between the puncture portion 221 and the photovoltaic frame 10, thereby improving the firmness of the fixing part 22 and preventing the vibration or other external force occurring during use from causing the angle code 20 to retreat or move.

[0053] Embodiment 2

[0054] This embodiment provides an angle code 20, which is substantially the same in structure as the angle code 20 provided in the first embodiment. The difference between the two is that: in this embodiment, reference Figure 5 As shown, stoppers 212 are protruding from two opposite side walls of the slot 211, so that the two ends of the fixing member 22 are respectively clamped between the stoppers 212 and the bottom wall of the slot 211. Compared with the first embodiment, the angle code body 21 in this embodiment can further limit the displacement and loosening of the fixing member 22, thereby further enhancing the connection stability between the angle code body 21 and the fixing member 22.

[0055] Embodiment 3

[0056] This embodiment provides an angle code 20 , which is substantially the same in structure as the angle code 20 provided in the first embodiment, except that the connection method between the fixing member 22 and the angle code body 21 is different.

[0057] Specifically, with reference to this embodiment, Figure 6 As shown, an adhesive layer 23 is connected between the fixing piece 22 and the angle code body 21, so that the fixing piece 22 and the angle code body 21 are bonded and connected by structural adhesive, which can avoid the use of riveting equipment, thereby improving the connection efficiency and convenience between the fixing piece 22 and the angle code body 21.

[0058] Further, refer to Figure 7 As shown, a portion of the angle bracket body 21 connected to the adhesive layer 23 is provided with an overflowing glue groove 214, which can collect excess structural glue to prevent it from overflowing to areas where glue should not be applied, thereby keeping the angle bracket body 21 neat, beautiful and safe.

[0059] Embodiment 4

[0060] This embodiment provides a frame fixing structure, including a plurality of photovoltaic frames 10 and the above-mentioned corner code 20. In the frame fixing structure, the surface of the photovoltaic frame 10 is provided with a corner code cavity 11, and after two adjacent photovoltaic frames 10 are spliced, the two corner code cavities 11 can be combined to form a cavity capable of accommodating the L-shaped corner code 20, and the corner code 20 can be used to achieve a fixed connection between the two adjacent photovoltaic frames 10.

[0061] Exemplarily, when the frame fixing structure is formed, the horizontal part of the angle code 20 is first inserted into the angle code cavity 11 of one of the photovoltaic frames 10. After the vertical part of the angle code 20 abuts against the end of one of the photovoltaic frames 10, the staff can press the photovoltaic frame 10 to make the puncture part 221 puncture and insert into the inner surface of the inner wall of the angle code cavity 11, so that the horizontal part of the angle code 20 is fixedly connected with one of the photovoltaic frames 10. Then, in the same way, another photovoltaic frame 10 is fixedly connected with the vertical part of the angle code 20, so that two adjacent photovoltaic frames 10 can be locked by one angle code 20. And through the puncture part 221 set on the angle code 20, the fixed connection between the angle code 20 and the photovoltaic frame 10 can be completed without pre-riveting points on the photovoltaic frame 10. Compared with the prior art, the combined connection method between the angle code 20 and the photovoltaic frame 10 can be simplified, saving the processing cost and equipment cost of the frame fixing structure. Moreover, the potential safety hazards of damage and deformation caused by pre-riveting points on the photovoltaic frame 10 made of composite materials can be eliminated, thereby ensuring the performance of the frame fixing structure.

[0062] Further, in this embodiment, referring to Figure 8 As shown, the inner wall of the angle code cavity 11 is provided with a flange 111, a part of the puncture portion 221 on the angle code 20 punctures and inserts into the inner wall of the angle code cavity 11, and another part of the puncture portion 221 abuts against the flange 111. Through the tight fit between the puncture portion 221 and the flange 111, the angle code 20 can be better prevented from moving, loosening or even slipping out of the angle code cavity 11.

[0063] Embodiment 5

[0064] The present embodiment provides a photovoltaic assembly, including a photovoltaic power generation panel and the above-mentioned frame fixing structure, wherein the frame fixing structure is arranged around the outer peripheral side of the photovoltaic power generation panel. In the above-mentioned frame fixing structure, the angle code 20 can be fixedly connected with the photovoltaic frame 10 without riveting, and the angle code 20 is locked with the photovoltaic frame 10 only by piercing the puncture portion 221 into the inner wall surface of the angle code cavity 11, thereby eliminating the operation of pre-punching rivets on the photovoltaic frame 10, saving the processing cost and equipment cost of the frame fixing structure, so that the production assembly efficiency and assembly cost of the photovoltaic assembly are greatly improved, thereby effectively enhancing the market competitiveness of the photovoltaic assembly.
