Abstract
Description

[0002] Corner brackets are widely used connecting components in the fields of construction, furniture and industrial manufacturing. They are mainly used to enhance the connection strength of intersecting components at corners. Depending on factors such as the magnitude of the force on the connected components, people will decide on the specific model, form and material type of the corner bracket.
[0003] However, in the existing technology, the photovoltaic frame is connected by corner brackets, which requires the ends of the frame to be cut at a 45° bevel, and then L-shaped right-angle corner brackets are embedded into the cavities of adjacent frames to complete the assembly. This results in the sharp edges and corners formed during processing, which pose a potential risk of personnel scratches. In addition, the metal burrs remaining at the joints after the frame is assembled need to be polished a second time. This extra process increases labor costs and reduces overall production efficiency. Utility Model Content

[0023] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0025] Please refer to Figures 1-4 This utility model provides a photovoltaic module installation system 200, which includes multiple photovoltaic frames 210, multiple photovoltaic corner brackets 100, and at least one pressure block 220. Each photovoltaic frame 210 is connected to one side of the photovoltaic module, and each photovoltaic corner bracket 100 is connected to one corner of the photovoltaic module. Therefore, each photovoltaic frame 210 has two ends connected to two photovoltaic corner brackets 100, and each photovoltaic corner bracket 100 is connected to two adjacent photovoltaic frames 210. The pressure block 220 is connected to the photovoltaic frames 210 and to a bracket, thereby mounting the photovoltaic frames 210, photovoltaic corner brackets 100, and photovoltaic modules on the bracket.
[0026] Specifically, the photovoltaic module in this embodiment has a square structure; therefore, there are four photovoltaic frame 210s and four photovoltaic corner brackets 100. The four photovoltaic frame 210s and four photovoltaic corner brackets 100 are connected sequentially to form a square frame. To improve installation stability, each photovoltaic frame 210 needs to be equipped with a pressure block 220; therefore, this embodiment has four pressure blocks 220, and each pressure block 220 is connected to one photovoltaic frame 210.
[0027] In this embodiment, each photovoltaic corner bracket 100 includes a mating part 110 and two embedding parts 120. The mating part 110 is bent to fit the corner of the photovoltaic module. The two embedding parts 120 are respectively connected to the two ends of the mating part 110. Each photovoltaic frame 210 is provided with a cavity 211. Since each photovoltaic corner bracket 100 is connected to two adjacent photovoltaic frames 210, the two embedding parts 120 are respectively embedded in the cavities 211 of the two adjacent photovoltaic frames 210, thereby achieving the purpose of connecting the photovoltaic frame 210 and the photovoltaic corner bracket 100.
[0028] It should be noted that in this embodiment, the mating part 110 includes a first bearing surface 112 for supporting the photovoltaic module, and the photovoltaic frame 210 includes a second bearing surface 213 for supporting the photovoltaic module. The first bearing surface 112 and the second bearing surface 213 are located on the same plane. This avoids misalignment between the photovoltaic frame 210 and the photovoltaic corner bracket 100, so as to smoothly support the photovoltaic module and improve stability.
[0029] Furthermore, after the embedding part 120 is embedded into the cavity 211 of the photovoltaic frame 210, the end of the mating part 110 abuts against the end of the photovoltaic frame 210. Since each photovoltaic corner bracket 100 is configured with two photovoltaic frames 210, the two ends of the mating part abut against the ends of the two adjacent photovoltaic frames 210 respectively. Thus, this embodiment enables the photovoltaic corner bracket 100 and the photovoltaic frame 210 to fit tightly together, avoiding any gap between the photovoltaic corner bracket 100 and the photovoltaic frame 210, so that the photovoltaic module will not be partially suspended, improving installation stability.
[0030] In this embodiment, a first groove 111 is provided on the outer side of the mating part 110, and a second groove 212 is provided on the outer side of the photovoltaic frame 210. After the two ends of the mating part 110 abut against the two adjacent photovoltaic frames 210, the first groove 111 communicates with the second groove 212 on the two photovoltaic frames 210. Since the mating part 110 is bent, the first groove 111 is also bent. In this embodiment, both ends of the mating part 110 are provided with openings, so that the pressure block 220 can enter the first groove 111 through the openings, thereby allowing the pressure block 220 and the first groove 111 to slide together.
[0031] Because the first slide groove 111 is bent, the pressure block 220 cannot slide at the bend of the first slide groove 111. Furthermore, to improve installation stability, each photovoltaic frame 210 needs to be equipped with a pressure block 220. Therefore, openings are required at both ends of the mating part 110 so that the two pressure blocks 220 can enter the first slide groove 111 through the two openings respectively. Understandably, each photovoltaic corner bracket 100 needs to slide in slidable engagement with two pressure blocks 220 so that the two pressure blocks 220 can slide from the first slide groove 111 into the second slide grooves 212 of the two adjacent photovoltaic frames 210 respectively. Subsequently, the pressure block 220 is connected to the photovoltaic frame 210 by connecting the inner wall of the corresponding second slide groove 212.
[0032] Understandably, since this embodiment includes a mating part 110, the ends of the photovoltaic frame 210 and the mating part 110 abut against each other. Therefore, in this embodiment, the photovoltaic frame 210 does not need to have its ends cut at a 45° bevel; this reduces the potential risk of workers being scratched due to the excessive sharpness of the ends of the photovoltaic frame 210. Furthermore, it avoids the need for secondary polishing of the photovoltaic frame 210, reducing labor costs and improving production efficiency.
[0033] The working principle of the photovoltaic module installation system 200 provided in this embodiment is as follows: First, connect multiple photovoltaic frames 210 to the side of the photovoltaic module so that the photovoltaic module and the second bearing surface 213 come into contact; then place the pressure block 220 into the first groove 111 through the opening.
[0034] Next, the embedding part 120 is embedded into the cavity 211 of the photovoltaic frame 210, so that the corners of the photovoltaic module of the photovoltaic corner bracket 100 are connected; so that the photovoltaic module and the second bearing surface 213 are in contact.
[0035] Subsequently, the sliding block 220 moves from the first slide groove 111 into the second slide groove 212, connecting the block 220, the first slide groove 111, and the bracket together, thereby installing the photovoltaic module onto the bracket.
[0036] It should be noted that the photovoltaic corner bracket 100 in this embodiment is a one-piece molded design and can be manufactured by injection molding or other methods.
[0037] Further, please refer to Figures 1-4In this embodiment, the pressure block 220 includes a sliding portion 221 and a connecting portion 222 connected to each other. The sliding portion 221 is slidably connected to the first slide groove 111 and the second slide groove 212. Understandably, the sliding portion 221 can enter the first slide groove 111 through an opening, and then move from the first slide groove 111 to the second slide groove 212, thereby abutting against the inner wall of the second slide groove 212. The connecting portion 222 is connected to the bracket, thereby using the pressure block 220 to install the photovoltaic module onto the bracket.
[0038] According to the above, the first groove 111 includes a limiting section 1111 and two mounting sections 1112, each mounting section 1112 communicating with a limiting section 1111 and an opening. The groove area of the limiting section 1111 is smaller than the side area of the sliding part 221; while the groove area of the mounting section 1112 is larger than the side area of the sliding part 221, that is, the groove area of the limiting section 1111 is smaller than the groove area of the mounting section 1112; thus, the sliding part 221 can enter from the groove of the mounting section 1112 and abut against the groove edge of the limiting section. Therefore, it can be understood that the groove edge of the limiting section 1111 can restrict the movement of the sliding part 221, thereby preventing the sliding part 221 from disengaging from the limiting section 1111.
[0039] In this embodiment, by setting the mounting section 1112, the sliding part 221 of the pressure block 220 can be inserted into the mounting section 1112 before the photovoltaic corner bracket 100 and the photovoltaic frame 210 are connected together. Then, the sliding part 221 is moved to the limiting section 1111 to prevent the pressure block 220 from detaching from the photovoltaic corner bracket 100. In this embodiment, the photovoltaic corner bracket 100 and the photovoltaic frame 210 can be connected together first, and then the mounting section 1112 can be used to allow the sliding part 221 of the pressure block 220 to enter the first sliding groove 111. Since the first sliding groove 111 and the second sliding groove 212 are connected, the mounting section 1112 and the second sliding groove 212 are also connected. By moving the sliding part 221, the sliding part 221 can move from the mounting section 1112 to the second sliding groove 212.
[0040] Further, please refer to Figures 1-5 The pressure block 220 also includes a mounting part 223, which is connected to the connecting part 222. The photovoltaic module installation system 200 also includes a C-shaped steel 230, which can be understood to be a bracket in this embodiment.
[0041] The C-shaped steel 230 has a groove 231, and the edge of the C-shaped steel 230 is bent toward the bottom of the groove 231 to form a slot 232; then the slot 232 and the hook part 223 are used to engage to connect the pressure block 220 and the C-shaped steel 230 together, thereby improving the installation stability.
[0042] It should be noted that in this embodiment, both sides of the C-shaped steel 230 are bent to form slots 232, that is, there are two slots 232. Correspondingly, there are also two hook parts 223, which are arranged on both sides of the connecting part 222.
[0043] In this embodiment, the connecting portion 222 abuts against the edge of the C-shaped steel 230, thereby sealing the opening of the groove 231. This transforms the groove 231 into a chamber after the connecting portion 222 and the C-shaped steel 230 are connected, thus dispersing stress and improving the stability of the connection. Furthermore, when the edge of the C-shaped steel 230 abuts against the connecting portion 222, the two hook portions 223 extend into the groove 231 and engage with the two slots 232 respectively.
[0044] Based on the above, the photovoltaic module installation system 200 in this embodiment also includes bolts, a connecting part 222 and a C-shaped steel 230 respectively provided with a first threaded hole and a second threaded hole, and the bolt is threadedly connected to the first bolt hole and the second threaded hole. Understandably, the bolt and its threaded rod pass through the groove 231, and the first of the connecting part 222 and the C-shaped steel 230 abuts against the bolt's nut, while the other abuts against the bolt's mating nut.
[0045] Therefore, this embodiment further improves installation stability through the snap-fit of the slot 232 and the hook-fitting part 223 and the threaded connection of the bolt; and prevents the pressure block 220 from shaking under the action of external forces such as strong wind.
[0046] Furthermore, in this embodiment, each embedding part 120 is provided with a serrated protrusion 121. When the embedding part 120 enters the cavity 211 of the photovoltaic frame 210, the protrusion 121 abuts against the inner wall of the cavity 211 to improve installation stability.
[0047] Understandably, slight dimensional errors may occur in the photovoltaic frame 210 during its production. The protrusion 121 compensates for these errors through slight deformation or selective contact, ensuring a tight fit between the corner bracket and the connector, and avoiding the risk of stress concentration or loosening caused by gaps. Furthermore, the protrusion 121 increases the friction between the insert 120 and the photovoltaic frame 210, reducing relative slippage.
[0048] According to the above, the embedding part 120 is provided with a guide slope 122; the protrusion 121 is located between the guide slope 122 and the mating part 110. In this embodiment, the guide slope 122 can guide the protrusion 121 into the cavity 211 and abut against the inner wall of the cavity 211; this avoids collision when the embedding part 120 extends into the cavity 211, so that the embedding part 120 and the photovoltaic frame 210 can be smoothly connected.
[0049] Furthermore, in this embodiment, each photovoltaic corner bracket 100 includes a first abutting portion 130, and each photovoltaic frame 210 includes a second abutting portion 214. The first abutting portion 130 is disposed on the first bearing surface 112 of the mating portion 110, while the second abutting portion 214 is disposed on the second bearing surface 213 of the photovoltaic frame 210; the first abutting portion 130 abuts against the corner of the photovoltaic module, while the second abutting portion 214 abuts against the side wall of the photovoltaic module; thereby fixing the photovoltaic module and preventing the photovoltaic module from detaching from the photovoltaic frame 210 and the photovoltaic corner bracket 100.
[0050] Furthermore, the first contact portion 130 and the second contact portion 214 do not act on the sun-facing surface of the photovoltaic module, thereby avoiding shading of the photovoltaic module and improving the power generation efficiency and power output of the photovoltaic module.
[0051] In summary, the photovoltaic corner bracket 100 in this embodiment is provided with a mating part 110 and two embedding parts 120. The two embedding parts 120 can be respectively connected to the cavities 211 of two adjacent photovoltaic frames 210, thereby connecting the photovoltaic corner bracket 100 and the photovoltaic frames 210 together. The two ends of the mating part 110 abut against the ends of two adjacent photovoltaic frames 210, thereby eliminating the need to cut the ends of the photovoltaic frames 210 into bevels, reducing the risk of workers being scratched, and ensuring worker safety; at the same time, it avoids secondary grinding of the photovoltaic frames 210, reducing labor costs and improving production efficiency. The first bearing surface 112 of the mating part 110 and the second bearing surface 213 of the photovoltaic frame 210 are located on the same plane to jointly support the photovoltaic module, avoiding the problem of unstable placement of the photovoltaic module due to misalignment.
[0052] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
