Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and in particular to a fixed installation device for photovoltaic modules. Background Technology

[0002] In the manufacturing and installation of photovoltaic (PV) modules, the frame, as a crucial component, plays a vital role in fixing, protecting, and supporting the module. However, traditional PV module frame designs present several significant technical challenges. Traditional frames typically feature mounting slots, requiring the application of sealant to secure the PV module during installation. This method has obvious drawbacks, such as inconsistent sealant application, potentially leading to poor sealant appearance and affecting the overall look. Furthermore, special curing conditions are required after frame installation, wasting time and impacting production efficiency. More importantly, the frame requires complex slot shapes to secure the PV module, increasing processing difficulty and cost.

[0003] To address these issues, quick-installation frame technology has emerged. For example, some patents propose a snap-fit ​​frame design that achieves quick installation through the snap-fit ​​connection of the upper and lower frame sections. However, this design still has several drawbacks: First, snap-fit ​​frames have complex shapes and are typically made using aluminum alloy profiles, resulting in higher costs; second, due to their complex structure, improper assembly during the assembly process can easily lead to poor snap-fit ​​performance, with mismatched snap teeth positions in different directions affecting the actual assembly effect; finally, the small contact area of ​​the snap-fit ​​frame's interlocking parts makes them prone to loosening in long-term outdoor hot and cold environments, causing the frame to lose its fixing function.

[0004] In summary, existing photovoltaic module frame designs have shortcomings in terms of cost, installation efficiency, structural strength, and long-term stability. There is an urgent need for a new frame design that is simple in structure, low in cost, easy to install, and has high structural strength. Utility Model Content

[0005] Based on the above analysis, the present invention aims to provide a fixed installation device for photovoltaic modules to solve the problems of traditional frame installation being inconvenient and the fixing method being unstable.

[0006] On the one hand, this utility model provides a fixed installation device for photovoltaic modules, including an outer frame and a support body. The outer frame and the support body are fixedly connected together by a connector, and the edge of the photovoltaic module is fixedly clamped between the outer frame and the support body. The outer frame and the support body are provided with a first shock-absorbing and buffering rubber strip in the area that directly contacts the photovoltaic module, and a second shock-absorbing and buffering rubber strip is provided in the mating gap between the outer frame and the support body.

[0007] Furthermore, the outer frame and the support are made of alloy material, and the surfaces of the outer frame and the support that contact the first shock-absorbing and buffering rubber strip have an uneven and rough structure.

[0008] Furthermore, the inner edge of the first shock-absorbing and buffering strip protrudes beyond the edge of the photovoltaic module.

[0009] Furthermore, the outer frame includes a first connecting area, a second connecting area, and a third area for support, fixation, or connection, and the support body is fixedly connected to the first connecting area and the second connecting area respectively.

[0010] Furthermore, the first connecting area, the second connecting area, and the third area are sequentially connected and form a C-shaped groove; the third area is provided with mounting holes for fixing the fixed mounting device to the required position; the support body includes a horizontally extending first support plate and a vertically extending second support plate, one end of the first support plate is fixedly connected to the second support plate, the second support plate is located within the C-shaped groove formed by the outer frame, and the bottom of the second support plate abuts against the third area; the first support plate is located below the first connecting area and is fixedly connected to the first connecting area by a connector, and the second support plate is located inside the second connecting area and is fixedly connected to the second connecting area by a connector.

[0011] Furthermore, the top of the second support plate is provided with an upward protrusion, and there is a gap between the top of the protrusion and the first connecting area.

[0012] Furthermore, the first connecting area is provided with a first outer hole; the first support plate is provided with at least one first inner hole, and the first outer hole can be adapted to any one of the first inner holes to provide the connector.

[0013] Furthermore, the first connecting area and the second connecting area extend horizontally, and the third area connects the first connecting area and the second connecting area and extends vertically, with the first connecting area and the second connecting area located on opposite sides of the third area; the support body includes a horizontally extending first support plate, a third support plate, and a vertically extending second support plate, with the first support plate, the second support plate, and the third support plate connected sequentially, and the first support plate and the third support plate located on opposite sides of the second support plate; the first support plate is located below the first connecting area and is fixedly connected to the first connecting area via a connector; the third support plate is located below the second connecting area and is fixedly connected to the second connecting area via a connector.

[0014] Furthermore, the connector is a rivet, screw, or pin.

[0015] Furthermore, the outer frame and the support body are generally elongated or right-angled.

[0016] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0017] (1) Using connectors such as rivets, screws or pins to fix the mounting device to the photovoltaic module, compared with the traditional aluminum alloy frame relying on sealing silicone to fix the components and the snap-fit ​​frame, this fastening method can provide a more stable, uniform and reliable fastening effect.

[0018] (2) By setting shock-absorbing and buffering strips in the areas where the outer frame and support directly contact the photovoltaic module, and filling the areas where the outer frame and support cooperate with each other with shock-absorbing and buffering strips, more energy can be absorbed when the module is impacted, thereby reducing the risk of the module breaking due to impact vibration.

[0019] (3) Through specific structural design, such as the protruding structure or stepped structure of the support, the "opening" phenomenon when the outer frame and the support are fixedly connected by connectors is avoided, ensuring the stability of the fastening effect. In addition, compared with the traditional method of injecting sealant or snap-on installation, the method of fixing by connectors is faster and simpler.

[0020] (4) The outer frame and support are made of alloy steel plate by cold bending, which has a simple structure and does not require complicated injection molding or rolling processes. Compared with the traditional aluminum alloy frame and the use of steel coils with a thickness of less than 1mm to form a complex structure by cold bending, the fixed installation device proposed in this utility model has low processing cost and low raw material cost.

[0021] (5) The alloy functional parts are made of one or more of the following materials: aluminum alloy, stainless steel, and polymer, with a thickness of 1-10 mm or a combination of multiple thicknesses. The design of the fixed installation device structure takes into account the selection of materials and optimization of structure, so that the fixed installation device can maintain a low cost while still having high structural strength. At the same time, the structural design of the fixed installation device (such as raised structure, filling shock-absorbing strips, etc.) also enhances the structural strength of the fixed installation device.

[0022] (6) The outer frame and the support can be bent to achieve the integration of the long and short sides, eliminating the corner code design when connecting the long and short sides in the traditional frame, thus simplifying the installation process and improving the ease of installation.

[0023] (7) On the same component, short frames of different thicknesses and sizes can be made using steel of different thicknesses to achieve matching installation. This can reduce the overall weight of the component while ensuring structural strength.

[0024] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained from the description and accompanying drawings, which are particularly pointed out. Attached Figure Description

Detailed Implementation

[0038] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0039] Example 1

[0040] like Figures 1-2 As shown, the photovoltaic module fixing and installation device in this embodiment is mainly used to provide support and protection during the fixing and installation of photovoltaic modules. It is generally a long, narrow channel steel structure, less than half the length of the photovoltaic module, and is positioned at the side edge of the photovoltaic module to fix and clamp it for easy installation. See also... Figure 1 Two fixed mounting devices are installed on each of the two long sides of the photovoltaic module. The photovoltaic module can be a bifacial double-glass module or other types of photovoltaic modules.

[0041] See Figures 3-4 The photovoltaic module fixing and mounting device in this embodiment consists of an outer frame 10, a support 20, a first shock-absorbing buffer strip 51, a second shock-absorbing buffer strip 52, and a connector 30. The outer frame 10 and the support 20 are fixedly connected together by the connector 30, clamping the edge of the photovoltaic module 40 in the middle. Simultaneously, to increase the buffering effect and reduce vibration transmission, the outer frame 10 and the support 20 are provided with the first shock-absorbing buffer strip 51 in the area directly in contact with the photovoltaic module 40, and the second shock-absorbing buffer strip 52 is provided in the mating gap between them. The connector 30 can be a conventional standard part such as a rivet, screw, or pin.

[0042] See Figure 5The outer frame 10 includes a first connecting area 101, a second connecting area 102, and a third area 103, which are connected sequentially to form a roughly C-shaped structure with a side-opening groove in the middle. A first external hole 104 is provided in the first connecting area 101, a second external hole 105 is provided in the second connecting area 102, and a bolt hole 106 is provided in the third area 103. Both the first external hole 104 and the second external hole 105 are used for the connector 30 to pass through. The bolt hole 106 is used to fix the mounting device to the required position using bolts.

[0043] The outer frame 10 is made of aluminum alloy and can be made of alloy steel plate with a certain thickness (1-10mm), such as stainless steel plate, through a simple cold bending process, resulting in a lightweight and high-strength structure. The portion of its surface that contacts the first shock-absorbing rubber strip 51 is roughened to create an uneven, rough structure (such as a toothed structure) to enhance the adhesion of the first shock-absorbing rubber strip 51. The C-shaped design facilitates cooperation with the support body 20, forming a stable clamping structure.

[0044] See Figure 3 , Figure 4 as well as Figure 6 The support body 20 includes a horizontally extending first support plate 201 and a vertically extending second support plate 202. The second support plate 202 is located in the groove formed by the outer frame 10 and abuts against the third area 103.

[0045] The first support plate 201 is located below the first connecting area 101 and has two first inner holes 204 arranged along the width direction of the fixing device. During use, one of these holes can be aligned with the first outer hole 104 as needed, and the first support plate 201 is fixedly connected to the first connecting area 101 via the connector 30. The second support plate 202 is located inside the second connecting area 102 (i.e., inside the C-shaped groove) and is fixedly connected to the second connecting area 102 via the connector 30. If greater structural strength is required for the fixing device, the first outer hole 104 and the first inner hole 204 near the second support plate 202 can be paired, such as... Figure 4 As shown, the cavity region 50 formed between the second support plate 202 and the second connecting area 102 can also be filled with reinforcing ribs (not shown in the figure) to further enhance the structural strength of the frame. The reinforcing ribs are optional independent structures, similar to inserting a steel bar into the cavity to increase strength. The material can be any alloy, stainless steel, or polymer. The reinforcing ribs are not connected to other structures; only holes need to be made to allow rivets to pass through.

[0046] The top of the second support plate 202 is provided with an upward protrusion 206, which has a gap with the first connection area 101 to avoid over-assembly.

[0047] The support body 20 is also made of aluminum alloy, and the first support plate 201 and the second support plate 202 are fixedly connected by welding or other means. The protrusion 206 of the second support plate 202 is designed to provide a positioning reference during assembly and ensure assembly accuracy. When using the connector 30 for fixed connection, it prevents excessive displacement of the left side of the outer frame 10 and the support body 20, ensures complete fit of the right side with the photovoltaic module 40, and guarantees the clamping effect.

[0048] The first shock-absorbing and buffer strip 51 is made of ethylene propylene diene monomer (EPDM) rubber, which has good elasticity and weather resistance. Its inner edge protrudes beyond the edge of the photovoltaic module 40 to provide a larger buffer area.

[0049] The second shock-absorbing and buffering strip 52 is also made of EPDM material and is filled in the gap between the outer frame 10 and the support 20 to further reduce vibration transmission and improve the stability of the overall structure.

[0050] Preferably, the surfaces of the first shock-absorbing and buffering rubber strip 51 and the second shock-absorbing and buffering rubber strip 52 are adhesive, which further improves the stability of the overall structure.

[0051] The connector 30 is made of stainless steel, which has good corrosion resistance and strength. The outer frame 10 and the support 20 are firmly connected together by a fixed connection to ensure a stable clamping of the photovoltaic module 40.

[0052] On the same component, steel of different thicknesses can be used to create two short frame sizes, allowing for compatible installation and reducing component weight. For example, in Figure 1 The four fixed mounting areas shown are constructed with steel of normal thickness to ensure the supporting function of the components within these areas. The remaining component edges, outside of the four fixed mounting areas, can be encased with similarly structured fixed mounting devices made of thinner steel. This only needs to protect the glass from impacts and does not require additional support.

[0053] The fixed installation device in this embodiment achieves stable clamping and effective cushioning of the photovoltaic module 40 through the combination of fixed connection and shock-absorbing rubber strips, thereby improving the installation stability and impact resistance of the module. Meanwhile, the choice of aluminum alloy material makes the device lightweight and high-strength, facilitating installation and maintenance.

[0054] Example 2

[0055] like Figure 7As shown, the photovoltaic module fixing and installation device in this embodiment 2 also includes an outer frame 10, a support 20, a first shock-absorbing buffer strip 51, a second shock-absorbing buffer strip 52, and a connector 30.

[0056] The parts that are the same as in Embodiment 1 will not be described again. The difference from Embodiment 1 is that the first connecting area 101 and the second connecting area 102 of the outer frame 10 both extend horizontally and are connected together by the vertically extending third area 103, and are respectively located on both sides of the third area 103, as shown below. Figure 7 As shown.

[0057] The structure of the support body 20 is similar to that of the outer frame 10, including a horizontally extending first support plate 201 and a third support plate 203, which are connected together by a vertically extending second support plate 202 and are located on both sides of the second support plate 202 respectively.

[0058] The first support plate 201 of the support body 20 is located below the first connection area 101 and is fixedly connected to the first connection area 101 by the connector 30. The third support plate 203 is located below the second connection area 102 and is fixedly connected to the second connection area 102 by the connector 30.

[0059] The second support plate 202 extends vertically and is located beside the third zone 103, serving to connect the first support plate 201 and the third support plate 203.

[0060] The first bolt hole 106 and the second bolt hole 207 of the outer frame 10 and the support body 20 are the bolt mounting holes when the photovoltaic module is actually installed outdoors using bolts.

[0061] In this embodiment, by designing the outer frame 10 and the support 20 into a stepped structure, misalignment of the outer frame 10 and the support 20 during assembly can be limited based on this feature. Furthermore, threads can be designed into the rivet mounting holes, and the rivets are also threaded. The rivets first undergo a thread tightening action to pre-fix the outer frame 10 and the support 20, and then a fixed connection is made to complete the fastening and fixing of the outer frame 10 and the support 20, ultimately achieving the clamping and fixing effect on the photovoltaic module 40.

[0062] Example 3

[0063] The photovoltaic module fixing and installation device in this embodiment 3 is suitable for the protection of the corners of the photovoltaic module 40, such as... Figure 8 As shown, the outer frame 10 and the support 20 are designed as a whole with right angles to accommodate photovoltaic modules 40 with different edge shapes.

[0064] The photovoltaic module fixing and mounting device of this embodiment 3 is applicable to the method of forming photovoltaic module 40 by partially cutting and bending the fixing and mounting device in embodiment 1, and finally installing it at the corner of the module.

[0065] refer to Figure 9 , Figure 9 a is a front view of the outer frame 10 (the front view is the direction of sunlight shining on the front of the component). Figure 9 b is a front view of the outer frame 10 after partial cutting. The cut outer frame 10 is then subjected to sheet metal bending, resulting in a 90-degree right-angled outer frame 10. Figure 10 As shown.

[0066] The support body 20 is treated in the same way as the outer frame 10. The treated outer frame 10 and support body 20 are assembled and installed at the corners of the photovoltaic module 40, ultimately forming protection for the corners of the photovoltaic module 40.

[0067] In this embodiment, the fixing device used at the corner of the photovoltaic module 40 primarily serves to protect the corners of the photovoltaic module 40. Therefore, its structural strength requirements are less than those for the fixing device installed on the long side of the module. Consequently, the thickness of the steel used in the corner fixing device can be less than the thickness of the steel used in the fixing device installed on the long side of the module. This combination of short frames with different thicknesses reduces the weight of the module without compromising its structural safety performance, thus improving the convenience of subsequent transportation and installation.

[0068] The outer frame 10 and the support 20 are fixedly connected by multiple connectors 30 evenly distributed in one or more columns along their length or right-angle side, thereby fixing and clamping the edge of the photovoltaic module 40 in the middle.

[0069] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present 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 the present utility model should be included within the protection scope of the present utility model.
