Technical Field

[0001] This application relates to the technical field of photovoltaic equipment, and particularly relates to a combined photovoltaic module frame. Background Art

[0002] The photovoltaic module frame plays a very important role in the photovoltaic system. The photovoltaic frame can effectively protect the solar panel from damage by the external environment, thereby extending the service life of the photovoltaic module. The frame also plays a role in strengthening the sealing performance of the module, preventing impurities such as moisture and dust from entering the interior of the module, and keeping the cells clean and operating efficiently.

[0003] The materials of the photovoltaic module frame mainly include aluminum alloy, steel, composite materials, etc. The aluminum alloy frame is light in weight, has high strength and rigidity, and occupies a mainstream position in the market. However, the strength of the aluminum alloy frame is not as good as that of the steel frame, and it is easy to be damaged in harsh environments, thus reducing the service life. At the same time, the cost is relatively high, increasing the installation investment. The strength of the steel frame is much higher than that of the aluminum alloy, and the cost is lower, but the weight is larger, which is not convenient for transportation and installation. The composite material has a low density and is easy to form, but the technology is not yet mature and the service life is unstable.

[0004] The applicant found through retrieval that the Chinese patent with the publication number CN220067344U discloses a photovoltaic module frame, a photovoltaic module and an installation structure of the photovoltaic module frame, which can avoid the occlusion of the frame on the back of the photovoltaic module, improve the power generation efficiency of the back of the photovoltaic module, and further improve the power generation efficiency of the entire photovoltaic module.

[0005] However, the above-mentioned photovoltaic module frame still adopts an integral structure, which is difficult to solve the problem that the strength of the aluminum alloy frame is not as good as that of the steel frame, and it is easy to be damaged in harsh environments, thus reducing the service life, while the strength of the steel frame is much higher than that of the aluminum alloy, the cost is lower, but the weight is larger, which is not convenient for transportation and installation. Utility Model Content

[0006] One technical problem to be solved by this application is that the strength of the aluminum alloy frame is not as good as that of the steel frame, and it is easy to be damaged in harsh environments, thus reducing the service life, while the strength of the steel frame is much higher than that of the aluminum alloy, the cost is lower, but the weight is larger, which is not convenient for transportation and installation.

[0007] To solve the above technical problem, an embodiment of this application provides a combined photovoltaic module frame, including: a frame, a bracket and silica gel;

[0013] In some embodiments, the bracket is of a hollow structure.

[0014] In some embodiments, one of the frame and the bracket is provided with a tenon structure, and the other is provided with a mortise structure. Through the cooperation of the tenon structure and the mortise structure, the fixed connection between the frame and the bracket is achieved.

[0015] In some embodiments, the frame is provided with a clamping groove, the shape of the silica gel is adapted to the clamping groove, and the silica gel is clamped in the clamping groove.

[0016] In some embodiments, the installation groove is provided with a plurality of sealing protrusions. When the photovoltaic panel is installed in the installation groove, the sealing protrusions abut against the photovoltaic panel.

[0017] In some embodiments, the sealing protrusions abut against the photovoltaic panel to form a sealing groove, and sealant is filled in the sealing groove.

[0035] It should also be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances. When it is described that a specific device is between a first device and a second device, an intermediate device may or may not exist between the specific device and the first device or the second device.

[0036] All terms used in this application have the same meanings as those understood by those of ordinary skill in the art to which this application pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, for example, should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such here.

[0037] Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the specification.

[0038] Refer to the appended drawings of the specification Figure 1 , which shows a schematic structural diagram of a combined photovoltaic module frame disclosed in an embodiment of this application.

[0039] Refer to the appended drawings of the specification Figure 2 , which shows a schematic structural diagram of a frame disclosed in an embodiment of this application.

[0040] Refer to the appended drawings of the specification Figure 3 , which shows a schematic structural diagram of a bracket disclosed in an embodiment of this application.

[0041] Refer to the appended drawings of the specification Figure 4 , which shows a schematic structural diagram of a silicone disclosed in an embodiment of this application.

[0042] An embodiment of the present application provides a combined photovoltaic module frame, including: frame 1, bracket 2, and silicone 3; the frame 1 is disposed on the bracket 2; the silicone 3 is disposed on the frame 1, and the silicone 3 forms an installation groove 31 for installing a photovoltaic panel 4; the frame 1 is made of aluminum alloy material; the bracket 2 is made of steel material.

[0043] It should be noted that aluminum alloy has a relatively high strength-to-weight ratio, which means that while providing sufficient strength, it is much lighter than steel. Using the frame 1 made of aluminum alloy material can significantly reduce the overall weight of the photovoltaic module, thereby reducing the difficulty and cost of transportation and installation.

[0044] Furthermore, the bracket 2 is made of steel material, providing higher structural strength and stability. Steel has better bending and impact resistance capabilities, ensuring that the photovoltaic module remains stable and safe under various harsh weather conditions such as strong winds and snow loads.

[0045] Furthermore, the silicone 3 has excellent elasticity and sealing properties, capable of forming a tight contact between the frame and the photovoltaic panel, preventing moisture, dust, or other contaminants from entering the interior of the module, thereby protecting the internal electrical components and ensuring the long-term stable operation of the photovoltaic module.

[0046] In the actual application process, due to the separate design of the aluminum alloy frame 1 and the steel bracket 2, during installation, the lighter aluminum alloy frame 1 can be first fixed to the silicone 3 part, and then the frame 1 can be installed on the steel bracket 2 through a simple method. This modular design can make the installation process more flexible and reduce the need for heavy installation equipment.

[0047] In the present utility model, the frame 1 and the bracket 2 are separately provided. The frame 1 is made of a relatively light aluminum alloy material, while the bracket 2 is made of a steel material with relatively high strength. On the premise of meeting the strength requirements of the module frame, the quality is reduced, facilitating transportation and installation.

[0048] In some embodiments, the bracket 2 is specifically made of galvanized aluminum-magnesium steel material.

[0049] It should be noted that galvanized aluminum-magnesium steel is coated with an alloy coating containing zinc, aluminum, and magnesium on the surface of the steel. This coating can form a dense oxide protective film when contacting air and water, greatly enhancing the corrosion resistance of the steel. This enables the bracket to be used for a long time without rusting in harsh environments such as humidity and salt spray, and is particularly suitable for outdoor photovoltaic modules.

[0050] In some embodiments, the bracket 2 is a hollow structure.

[0051] It should be noted that the hollow structure significantly reduces the weight of the bracket 2 compared to the solid structure. This not only helps to reduce the transportation and installation costs of the photovoltaic module, but also reduces the labor intensity during installation, making the construction process simpler and faster.

[0052] In some embodiments, one of the frame 1 and the bracket 2 is provided with a tenon structure 5, and the other is provided with a mortise structure 6. Through the cooperation of the tenon structure and the mortise structure, the fixed connection between the frame 1 and the bracket 2 is achieved.

[0053] It should be noted that through the cooperation of the tenon and the mortise, the frame 1 and the bracket 2 can be easily snapped together without using additional fasteners such as bolts and nuts, simplifying the installation process, reducing the installation steps and tool usage. This helps to improve the installation efficiency, especially in the case of large-scale installation or complex on-site conditions.

[0054] In some embodiments, a clamping groove 11 is provided on the frame 1, and the shape of the silicone 3 is adapted to the clamping groove, and the silicone 3 is clamped in the clamping groove.

[0055] It should be noted that by clamping the silicone 3 in the clamping groove 11, the silicone can be firmly fixed on the frame 1. This tight fit can effectively prevent the silicone 3 from falling off or shifting, ensuring that the sealing performance of the photovoltaic module will not be affected by external factors such as vibration, thermal expansion and contraction, etc., thereby providing reliable waterproof, dustproof and anti-pollution capabilities.

[0056] Refer to the attached drawings of the specification Figure 5 , which shows a schematic structural diagram of another combined photovoltaic module frame disclosed in the embodiments of the present application.

[0057] In some embodiments, a plurality of sealing protrusions 32 are provided on the mounting groove 31. When the photovoltaic panel 4 is installed in the mounting groove 31, the sealing protrusions 32 abut against the photovoltaic panel 4.

[0058] It should be noted that after the sealing protrusions 32 abut against the photovoltaic panel 4, multiple sealing contact points are formed. These contact points can effectively block external pollutants such as moisture, dust, and dirt from entering the interior of the mounting groove, thereby further enhancing the sealing performance of the photovoltaic module and ensuring that the internal components are protected from the environment. At the same time, the gaps between the plurality of sealing protrusions can serve as tiny drainage channels to prevent moisture from accumulating between the photovoltaic panel and the mounting groove. This helps to quickly drain a small amount of moisture that may enter, reducing the risk of corrosion or leakage caused by moisture retention.

[0059] In some embodiments, the sealing protrusions 32 abut against the photovoltaic panel to form a sealing groove, and a sealing glue 7 is filled in the sealing groove.

[0060] It should be noted that by filling the sealing groove with the sealant 7, a double sealing effect is achieved. The sealing protrusion 32 itself already provides a basic sealing function, and the filling of the sealant 7 further enhances this sealing effect, effectively preventing moisture, dust, air, and pollutants from entering the interior of the photovoltaic module, thereby improving the overall sealing performance of the photovoltaic module.

[0061] Refer to the attached Figure 6 illustrates a schematic structural diagram of another combined photovoltaic module frame disclosed in the embodiments of the present application.

[0062] In some embodiments, a first heat dissipation hole 8 is provided at the bottom of the mounting groove 31 for the silica gel, and a second heat dissipation hole 9 is provided on the frame 1. The first heat dissipation hole 8 is communicated with the second heat dissipation hole 9.

[0063] It should be noted that by providing the first heat dissipation hole 8 and the second heat dissipation hole 9 and making them communicate, a natural convection heat dissipation channel is formed. Hot air can be discharged from the interior of the module through these heat dissipation holes, and cold air enters, realizing effective natural convection heat dissipation. This helps to reduce the temperature of the photovoltaic panel and the bracket, thereby improving the power generation efficiency and service life of the photovoltaic module. The photovoltaic module generates a certain amount of heat during operation, especially in high-temperature or strong sunlight environments. If the heat cannot be effectively dissipated, it may cause the temperature of the module to be too high, thereby affecting its efficiency and life. The design of the heat dissipation holes can effectively discharge the accumulated heat, prevent overheating, and ensure that the photovoltaic module operates within an efficient temperature range.

[0064] In some embodiments, heat dissipation fins are provided on the outer side of the frame 1.

[0065] It should be noted that the design of the heat dissipation fins significantly increases the surface area of the frame, enabling more heat to be dissipated through radiation and convection. By increasing the surface area in contact with the air, the heat dissipation fins can accelerate the dissipation of heat inside the frame and the photovoltaic module, reduce the overall temperature, and thereby improve the efficiency and life of the photovoltaic module.

[0066] In some embodiments, a waterproof coating is provided on the surfaces of the frame 1 and the bracket 2.

[0067] It should be noted that by coating a waterproof coating on the surfaces of the frame and the bracket, the aging process of the materials can be significantly slowed down, and the performance degradation caused by long-term exposure to outdoor environments such as wind, rain, and sunlight can be reduced. This can greatly extend the overall service life of the photovoltaic module and the bracket, and reduce the frequency of maintenance and replacement.

[0068] Through the above technical solution, the combined photovoltaic module frame provided by the present application has the frame and the bracket separately arranged. The frame is made of aluminum alloy with a relatively light weight, while the bracket is made of steel with a relatively high strength, which reduces the mass while ensuring the strength requirement of the module frame, facilitating transportation and installation.

[0069] So far, the embodiments of the present application have been described in detail. To avoid obscuring the concept of the present application, some details well known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solution disclosed herein based on the above description.

Those skilled in the art should understand that the above embodiments can be modified or some technical features can be equivalently replaced without departing from the scope and spirit of the present application.
