[0044] The embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below are exemplary only, and are not intended to limit the present application.

[0045] The present application aims to at least solve one of the technical problems in the related art. To this end, the present application proposes a frame, a photovoltaic module, and a photovoltaic system, which can improve the installation efficiency of the photovoltaic module.

[0046] The following description is made with reference to the accompanying drawings. Figures 1-4 A frame according to an embodiment of the present application is described.

[0047] As shown in Figure 1 and Figure 3 A frame applied to a photovoltaic module includes a plurality of side beams 10, at least one side beam 10 forms a clamping portion 130 for clamping a laminate, and a clamping structure 140 for clamping with a mounting bracket 20 and a connecting structure 150 for threaded connection with the mounting bracket 20 are respectively formed on different wall surfaces.

[0048] The frame of the photovoltaic module can evenly share the pressure through the plurality of side beams 10, thereby enhancing the overall stability and deformation resistance of the photovoltaic module, wherein the side beam 10 is used to constitute the outer frame of the photovoltaic module, and plays a role of protecting and supporting the photovoltaic module, the side beam 10 includes a clamping portion 130 for clamping a laminate, the laminate is the core part of the photovoltaic module, and is usually composed of a plurality of photovoltaic cell layers, the clamping portion 130 is responsible for firmly clamping the laminate of the photovoltaic module, reducing looseness or damage occurring during installation or transportation, and the side beam 10 further respectively forms a clamping structure 140 for clamping with a mounting bracket 20 and a connecting structure 150 for threaded connection with the mounting bracket 20 on different wall surfaces.

[0049] As shown in Figure 4 , the clamping structure 140 can be in the form of a clamping groove 141, which is used to realize the quick connection between the photovoltaic module and the mounting bracket 20, so as to quickly dock the photovoltaic module with the mounting bracket 20, improve the stability after installation, and allow a certain degree of adjustment of the position of the module. During installation, it can be more flexible to fine-tune, improve the overall installation accuracy, and at the same time, the clamping structure 140 can also reduce the installation time and labor cost, and improve the installation efficiency of the photovoltaic module.

[0050] Unlike the clamping structure 140, the connecting structure 150 is mainly used to more firmly connect the photovoltaic module and the mounting bracket 20 through threaded connection or other fastening methods. Threaded connection can provide strong mechanical connection strength and stability, and can adapt to greater wind pressure or other external forces.

[0051] Combining the clamping structure 140 and the connecting structure 150 on the same side beam 10 can meet different installation requirements. For example, the clamping structure 140 can be used to simplify the installation process and improve efficiency, while the connecting structure 150 is used to improve long-term stability and firmness. The combination of clamping and threaded connection structure 150 makes installation more efficient. After preliminary installation through clamping, threaded connection can be used for further reinforcement to provide stronger tensile strength and durability.

[0052] In related art, the frame of the photovoltaic module is basically in the form of a conventional frame, and the connection and installation method of the frame is mostly the traditional large pressing block or medium pressing block, which has high connection and installation complexity, long installation time, and cannot adapt to balcony and window sill scenes, and there is room for improvement. Based on the above considerations, the clamping structure 140 and the connecting structure 150 are combined on the same side beam 10, and the clamping structure 140 and the connecting structure 150 can be used in cooperation with the frame, so as to meet different installation requirements.

[0053] According to the frame provided in the embodiments of the present application, the cooperation of the clamping structure 140 and the connecting structure 150 can improve the installation efficiency of the photovoltaic module and improve the reliability and long-term service life of the photovoltaic system.

[0054] In some embodiments, as shown in Figure 3 and Figure 4 , the side beam 10 includes a side beam body 110, the side beam body 110 forms a cavity 120, and the clamping structure 140 is located on the side of the side beam body 110 away from the opening of the clamping portion 130.

[0055] The side beam body 110 is the main part of the photovoltaic module frame, which is used to bear most of the mechanical load and provide overall structural support for the photovoltaic module. The side beam body 110 forms a cavity 120, that is, the inside of the side beam 10 is a hollow structure or has a specific cavity. The cavity 120 can be used to accommodate components such as fasteners required during installation, thereby simplifying the overall structure of the frame.

[0056] The side beam 10 also includes a clamping part 130, which is distributed vertically with the side beam body 110. One side of the clamping part 130 and the side beam body 110 form an opening for clamping the laminate, while the other side of the side beam body 110 is away from the opening of the clamping part 130 and is used to contact the mounting bracket 20. The snap-fit ​​structure 140 is located on the side of the side beam body 110 away from the opening of the clamping part 130 and is used to snap-fit ​​with the mounting bracket 20, thereby realizing the rapid and stable installation of the photovoltaic module.

[0057] It is understandable that by setting the snap-fit ​​structure 140 on the side of the side beam body 110 away from the opening of the clamping part 130, the mechanical strength of the frame can be improved, and at the same time, it is easier to connect with the mounting bracket 20, which helps to improve installation efficiency.

[0058] In some embodiments, such as Figure 3 and Figure 4 As shown, the side beam body 110 includes a first wall surface 111 connected to the mounting bracket 20 via a connecting structure 150, and a second wall surface 112 snapped into the mounting bracket 20. The snapping structure 140 is located on the second wall surface 112 and close to the first wall surface 111.

[0059] The first wall surface 111 of the side beam body 110 is connected to the mounting bracket 20 through a connecting structure 150. The connecting structure 150 usually adopts a threaded connection or other connection method to provide strong fixation and support, and improve the stability between the side beam 10 and the mounting bracket 20. The second wall surface 112 of the side beam body 110 is snapped into the mounting bracket 20. The snapping structure 140 is usually a snapping component such as a slot 141, which facilitates quick connection with the mounting bracket 20. In addition, the first wall surface 111 and the second wall surface 112 are perpendicular and adjacent.

[0060] The second wall surface 112 is provided with a snap-fit ​​structure 140 for snapping with the mounting bracket 20. The side beam 10 and the mounting bracket 20 can be fixed together by a simple push-in operation. At the same time, the snap-fit ​​structure 140 is close to the first wall surface 111 to provide stability for the initial installation and facilitate quick docking.

[0061] Understandably, the snap-fit ​​structure 140 simplifies the installation process, the connection structure 150 improves the strength and long-term stability of the connection, and the snap-fit ​​structure 140, being close to the first wall surface 111, provides convenient positioning and support during initial installation, thereby improving installation efficiency and enhancing the safety and stability of the photovoltaic system in long-term use.

[0062] In some embodiments, such as Figure 1 and Figure 3 As shown, the first wall surface 111 includes a first extension 113, the first extension 113 is provided with a connecting structure 150, the connecting structure 150 is used for threaded connection with the mounting bracket 20.

[0063] The first wall surface 111 of the side beam body 110 includes a first extension 113. The first extension 113 does not participate in forming the cavity 120. That is, the part of the first wall surface 111 excluding the first extension 113 is the wall surface of the cavity 120. The first extension 113 is provided with a connection structure 150 for threaded connection with the mounting bracket 20. For example, the connection structure 150 can be a threaded hole for threaded connectors to pass through. The connection structure 150 is mainly used to connect the side beam 10 and the mounting bracket 20, and can also enhance the overall support function of the first wall surface 111.

[0064] Threaded connections are a common and reliable method of connection, offering a longer service life and better resistance to loosening. They provide high-strength fixation and stable connections, helping frames withstand greater external forces or long-term use.

[0065] It is understood that the first extension 113 and the threaded connection structure 150 thereon included in the first wall 111 can provide a robust, stable and easily adjustable fixing method to strengthen the connection between the side beam 10 and the mounting bracket 20.

[0066] In some embodiments, such as Figure 3 and Figure 4 As shown, the second wall surface 112 protrudes into the cavity 120 at one end near the first wall surface 111, and a slot 141 is provided in the protruding area. The snap-fit ​​structure 140 includes the slot 141.

[0067] The second wall 112 protrudes into the cavity 120 at one end near the first wall 111, that is, a part of the second wall 112 extends into the cavity 120, forming a certain structural extension. The protruding area is used to enhance the relative positional stability between components, and also provides a material basis for the formation of the slot 141.

[0068] The slot 141 is a structure that can receive mating parts and is usually used to achieve fast and stable fixation. In addition, the slot 141 has a strong locking ability, which can prevent the locked parts from falling off due to external force or vibration after installation. The slot 141 can be formed by digging a groove on the side of the protruding area of ​​the second wall 112 away from the cavity 120. The thickness of each wall of the slot 141 is basically the same to maintain the structural stability of the second wall 112.

[0069] The slot 141 of the frame engages with the buckle on the mounting bracket 20, which can fix the components by simple insertion or snap-fit, so that the frame will not easily shift or loosen when subjected to external force, thereby significantly reducing installation time and complexity. In addition, the slot 141 can reduce the space occupied by the connector and optimize space utilization.

[0070] Understandably, the combination of the protruding area of ​​the second wall 112 and the slot 141 structure can provide a connection method that is both stable and easy to install. The protruding area can enhance the support and docking accuracy of the second wall 112, while the slot 141 and the snap-fit ​​structure 140 can further strengthen the firm connection between the components.

[0071] In some embodiments, such as Figure 4 As shown, the side wall of the slot 141 near the first wall surface 111 is the first side wall 142. The first side wall 142 slopes inward from the side near the bottom wall to the side away from the bottom wall into the slot 141. The side wall of the slot 141 away from the first wall surface 111 is the second side wall 143. The second side wall 143 is perpendicular to the bottom wall of the slot 141.

[0072] The side wall of the slot 141 near the first wall surface 111 is the first side wall 142, and the side wall of the slot 141 away from the first wall surface 111 is the second side wall 143. The first side wall 142 is an extension of the first wall surface 111. At the same time, the first side wall 142 slopes inward from the side near the bottom wall to the side away from the bottom wall into the slot 141, that is, the angle formed by the first side wall 142 and the bottom wall is an acute angle. In addition, the second side wall 143 and the bottom wall are both part of the second wall surface 112, and the second side wall 143 is perpendicular to the bottom wall.

[0073] Specifically, the opening of the slot 141 is narrower near the bottom wall and wider away from the bottom wall. The cross-sectional shape of the slot 141 can be regarded as a right trapezoid. This tilt angle helps the inserted part to be more easily aligned during installation, reducing the possibility of misalignment and jamming. In addition, the tilted first side wall 142 can be used to lock the inserted part, forming a structure that is easy to enter but difficult to exit, thereby enhancing the stability of the snap-fit ​​and making the position of the inserted part in the slot 141 more stable, and less likely to loosen or fall off.

[0074] Understandably, the design of the slot 141, combined with the inclined first sidewall 142 and the vertical second sidewall 143, can improve assembly accuracy and enhance fixing ability.

[0075] In some embodiments, such as Figure 4 As shown, the wall connection of the slot 141 is chamfered, and the first side wall 142 and the second side wall 143 are chamfered on the side away from the bottom wall.

[0076] The chamfering design at the wall connection of the slot 141 and on the side of the first side wall 142 and the second side wall 143 away from the bottom wall can effectively reduce stress concentration at sharp or acute corners. Under stress conditions, acute corners are places where stress concentrates, which may cause cracks or damage to the material. By setting chamfers, stress can be dispersed, extending the service life of the slot 141 and its accessories. In addition, chamfers can also reduce the risk of cracks spreading from sharp corners, thereby improving the durability and reliability of the overall structure.

[0077] During installation, the chamfers on the side of the first sidewall 142 and the second sidewall 143 away from the bottom wall allow the inserted component to smoothly enter the slot 141 without getting stuck or interfering, reducing damage or wear during installation and disassembly, thereby improving assembly efficiency. The chamfers at the joint of the slot 141 walls provide a buffer area at the intersection of the two walls, reducing the risk of cracks in the joint due to inaccurate processing or uneven stress.

[0078] The chamfer angle is usually between 45° and 90°, and can be selected according to the actual application requirements. For example, a larger angle can provide a wider transition surface, which is suitable for stronger pressure resistance or shock resistance requirements, while a smaller angle is suitable for occasions that require fine machining and high-precision fit.

[0079] For example, the fillet radius of the chamfer on the inclined surface of the first sidewall 142 is 0.2 mm, and the fillet radius of the chamfer on the non-inclined surface of the first sidewall 142 is 1 mm.

[0080] Understandably, the chamfered design on slot 141 can improve the efficiency and accuracy of precision assembly, and also help to enhance the strength of the connection and reduce damage caused by stress concentration.

[0081] In some embodiments, such as Figure 3 As shown, the clamping part 130 includes a second extension 131 and a clamping arm 132, and the clamping arm 132 has a groove 133 on the side facing the side beam body 110.

[0082] The clamping part 130 includes a second extension 131 and a clamping arm 132. The second extension 131 extends toward the second wall surface 112 in a direction away from the first wall surface 111. The clamping arm 132 is located on the side of the second extension 131 away from the first wall surface 111. One end of the clamping arm 132 is connected to the second extension 131, and the other end forms an opening with the side beam body 110.

[0083] The clamping arm 132 typically functions to clamp or support, and can make close contact with other components, such as laminates, in some way. The clamping arm 132 has a groove 133 on the side facing the side beam body 110. When the clamping arm 132 clamps the laminate, the groove 133 can be used to cooperate with other components, such as structural adhesive, to fix the laminate to the frame. At the same time, the laminate is usually composed of multiple layers of materials, and the surface is relatively fragile or easily damaged. The design of the groove 133 allows the clamping arm 132 to contact the edge of the workpiece only in a certain area, reducing the risk of indentation or damage to the surface of the laminate.

[0084] In addition, during processing or assembly, the groove 133 also helps the laminate to be unloaded smoothly, making it easier to separate the contact point between the clamping arm 132 and the laminate, thereby reducing friction and the risk of jamming during unloading.

[0085] It is understood that the clamping part 130 includes a second extension 131 and a clamping arm 132. The clamping arm 132 has a groove 133, which can increase the contact force between the clamping part 130 and the clamped object, and improve the stability and reliability of clamping.

[0086] In some embodiments, such as Figure 3 As shown, the groove 133 has a recess on the side wall near the second extension 131, and the recess is close to the bottom wall of the groove 133.

[0087] When the clamping arm 132 clamps the laminate, the groove 133 can be used to cooperate with other components, such as structural adhesive, to fix the laminate to the frame. At the same time, the laminate is usually composed of multiple layers of materials, and the surface is relatively fragile or easily damaged. The design of the groove 133 allows the clamping arm 132 to contact the edge of the workpiece only in a certain area, reducing the risk of indentation or damage to the surface of the laminate.

[0088] Furthermore, during processing or assembly, the groove 133 also facilitates the smooth unloading of the laminate, making it easier to separate the contact point between the clamping arm 132 and the laminate, thereby reducing friction and the risk of jamming during unloading. The groove 133 has a recess on the side wall near the second extension 131, and the recess is close to the bottom wall of the groove 133, which can reduce the risk of excessive concentrated pressure on a certain part, help reduce the risk of deformation or damage to the laminate, and also help separate the frame from the laminate, reducing the situation of laminate sticking or jamming.

[0089] Understandably, by setting the recess, the distribution and stability of the clamping force can be optimized, the performance of the clamping arm 132 can be improved, a more uniform distribution of clamping force can be achieved, and wear and slippage can be reduced.

[0090] This application also provides a photovoltaic module, including a laminate and a frame, with the frame holding the laminate.

[0091] Laminated components are the core of photovoltaic modules. They are typically composed of photovoltaic panels, transparent front covers, back sheets, and encapsulation materials, and are responsible for converting light energy into electrical energy. These materials are processed through a special lamination process to form an integral structure that not only has excellent power generation performance but also good weather resistance and mechanical strength, enabling it to work stably for a long time in various harsh environments.

[0092] The frame is the supporting and protective structure of photovoltaic modules. It is usually made of metal materials such as aluminum alloy and stainless steel or composite materials. It can enhance the overall structural strength of photovoltaic modules and improve their compressive strength. The installation between the laminate and the frame usually adopts various methods, such as adhesive and snap-fit ​​connection, to ensure that the laminate and the frame are tightly fitted and firmly connected during the installation process, so as to reduce the loosening or falling off during subsequent use.

[0093] Understandably, by securely fixing the laminate within the frame, a complete and reliable photovoltaic module can be formed, which can meet the needs of various photovoltaic power generation systems.

[0094] This application also provides a photovoltaic system, such as... Figure 1 and Figure 2 As shown, it includes a mounting bracket 20 and a photovoltaic module, with the photovoltaic module mounted on the mounting bracket 20.

[0095] A photovoltaic (PV) system is a system that uses solar energy to generate electricity. It mainly consists of PV modules, mounting brackets 20, electrical systems, and energy storage systems. Among them, PV modules are the core part of the PV system, responsible for converting sunlight into electrical energy. PV modules include laminates and frames. The laminate is composed of multiple solar cells connected in series or parallel. These cells are encapsulated together through a lamination process to form a module with waterproof and pressure-resistant capabilities. The laminate is installed on the frame, which is used to support and protect the laminate.

[0096] Mounting bracket 20 is mainly used to install and fix photovoltaic modules on the roof or ground of a building. For example, mounting bracket 20 for roof mounting is usually made of lightweight metal bracket, such as aluminum alloy or stainless steel, to support photovoltaic modules while reducing the load on the roof.

[0097] The electrical components of a photovoltaic system typically include inverters, cables, and junction boxes. Inverters are used to convert the direct current generated by the photovoltaic modules into alternating current for home use or to feed into the grid. Cables and junction boxes are used to connect the photovoltaic modules, inverters, and energy storage systems.

[0098] Energy storage systems typically include energy storage devices, whose core function is to store electrical energy. These devices consist of multiple batteries and can be used in energy storage power stations, wind power generation systems, solar power generation systems, mobile power systems, or temporary power supply systems. A common type of energy storage system is lithium battery energy storage, which can store electrical energy as needed and output it at appropriate times. For example, energy storage devices can store electrical energy during off-peak hours and provide power to relevant users or electrical devices during peak hours.

[0099] Energy storage devices can convert electrical energy into chemical energy and store it through batteries. When the battery is charging, an external power source provides electrical energy, which is stored in the positive and negative electrodes of the battery through electrochemical reactions. When electrical energy is needed, the battery converts the stored chemical energy into electrical energy through electrochemical reactions to supply the external load.

[0100] Understandably, a photovoltaic system converts solar energy into electrical energy for home or industrial use through the coordinated work of photovoltaic modules and mounting brackets 20. Installing photovoltaic modules on mounting brackets 20 can improve stability and power generation efficiency.
