[0047] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0048] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0049] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0050] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0051] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0052] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0053] See Figure 1 This application provides a photovoltaic power generation device, which includes a plurality of photovoltaic tiles 10, a frame 20, and a shading mechanism 30. The plurality of photovoltaic tiles 10 are arranged at intervals along a first direction. The frame 20 has a shading end 201 and a connecting end 202 disposed opposite to each other. The connecting end 202 is fixed to the bottom of the photovoltaic tile 10 and is located between two adjacent photovoltaic tiles 10. The connecting end 202 is used to fix the photovoltaic tile 10. The shading end 201 is closer to the outer edge of the photovoltaic tile 10 than the connecting end 202. The shading mechanism 30 is detachably connected to the shading end 201 and is disposed between two adjacent photovoltaic tiles 10 to shade the connecting end 202. (See reference...) Figure 1 The X direction is the first direction, and the first direction is the height direction.

[0054] Applying the technical solution of this application, the connecting end 202 of the frame 20 is close to the center of the photovoltaic tile 10, and the shading end 201 is close to the outer edge of the photovoltaic tile 10. The connecting end 202 is detachably connected to other structures, and the shading mechanism 30 is detachably connected to the shading end 201. When the photovoltaic power generation device is working normally, the shading mechanism 30 can effectively shade the connecting end 202 and other structures between two adjacent photovoltaic tiles 10, thereby ensuring the uniformity of the overall appearance of the photovoltaic power generation device. When a single or partial photovoltaic tile 10 needs to be replaced or repaired, only the corresponding shading mechanism 30 needs to be removed to expose the corresponding connecting end 202, and then the corresponding connecting end 202 can be disassembled. This configuration allows for simple and efficient disassembly of the photovoltaic tile 10 without disassembling a large area of ​​unrelated photovoltaic tiles 10, thereby improving the maintenance efficiency of the photovoltaic power generation device and reducing maintenance costs and labor costs for workers.

[0055] Furthermore, since the shading mechanism 30 is detachably connected to the shading end 201 and the connecting end 202 is detachably connected to other structures in this application, the photovoltaic tile 10 adopts a prefabricated design, which makes construction simple and quick and has high installation efficiency, thereby shortening the construction cycle. Moreover, the above-mentioned assembly method is suitable for various photovoltaic tile 10 types and building types, which is conducive to large-scale promotion and use.

[0056] In some embodiments, the photovoltaic tile 10 is provided with a waterproof structure such as a flow guide strip.

[0057] In some embodiments, the frame 20 can be a visible frame, with the shading end 201 protruding from the outer edge of the photovoltaic tile 10. When observed along the direction of light illumination, the frame 20 can be observed. Alternatively, the frame 20 can be a hidden frame, with the shading end 201 located inside the outer edge of the photovoltaic tile 10. When observed along the direction of light illumination, the frame 20 cannot be observed.

[0058] In some embodiments, the frame 20 may be made of metal materials such as aluminum alloy, stainless steel, carbon steel, copper, galvanized steel, or other materials that meet strength requirements.

[0059] In this application, the photovoltaic power generation device also includes a support 40 and a tile strip 50. The tile strip 50 is fixed to the mounting surface, the support 40 and the tile strip 50 are detachably connected, and the connection end 202 is detachably connected to the support 40.

[0060] In some embodiments, the batten strip 50 may be made of metal materials such as aluminum alloy, galvanized steel, and stainless steel; it may also be made of wood such as anti-corrosion wood and OSB board; or it may be made of materials such as PVC and ABS.

[0061] In some embodiments, the support 40 may be made of metal materials such as aluminum alloy, stainless steel, carbon steel, copper, galvanized steel, or other materials that meet strength requirements.

[0062] See Figure 2 The shading mechanism 30 includes a shading unit 31 and a sealing unit 32. The shading unit 31 is detachably connected to the shading end 201 to shade the connecting end 202. The sealing unit 32 is detachably connected to the shading unit 31 and abuts against the adjacent photovoltaic tile 10. With this configuration, the shading mechanism 30 can effectively block the intrusion of moisture, dust, and other impurities, prevent rainwater seepage, improve the safety of the installation surface, and extend the service life of both the installation surface and the photovoltaic tile 10.

[0063] In some embodiments, the length of the shading unit 31 is an integer multiple of the length of a single photovoltaic tile 10. This arrangement, with its integer multiple size relationship, allows the shading unit to terminate at the natural seam between two adjacent photovoltaic tiles, or for both ends of the shading unit to be located at the same position on the photovoltaic tiles at both ends that it can shade. This avoids the problems of uneven overlap or the need for additional cutting caused by non-standard lengths, and enhances the overall integrity and uniformity after installation.

[0064] In some embodiments, the sealing unit 32 is a waterproof strip, which can be made of materials such as PVC, EPDM, silicone rubber, thermoplastic elastomer, polyurethane, neoprene rubber, nitrile rubber, modified PVC, PEVA composite material, and ABS.

[0065] In some embodiments, the shielding unit 31 may be made of metal materials such as aluminum alloy, stainless steel, carbon steel, copper, galvanized steel, etc., or it may be made of glass.

[0066] In some embodiments, if the entire photovoltaic tile 10 cannot be installed at the edge of the mounting surface, a supporting tile is usually installed at the edge of the mounting surface, but the supporting tile cannot perform photoelectric conversion.

[0067] In some embodiments, the light reflectivity of the photovoltaic tile 10 is between 90% and 110% of the light reflectivity of the photovoltaic tile 10. The photovoltaic tile and the shading unit 31 are made of the same or similar materials, so as to achieve a uniform and homogeneous overall effect and improve the aesthetics of the overall appearance.

[0068] In some embodiments, staff can flexibly decide whether the mounting surface needs to be waterproof, depending on the requirements.

[0069] See Figure 3 The shielding unit 31 and the shielding end 201 are detachably connected via a snap-fit ​​structure. This design facilitates the installation and removal of the shielding unit 31 and the shielding end 201, reducing the difficulty of on-site installation.

[0070] Specifically, the snap-fit ​​structure includes a first connecting portion 21, a first bent portion 22, a second connecting portion 311, and a second bent portion 312. The blocking end 201 has the first connecting portion 21 and the first bent portion 22, with a first groove 23 between them. The blocking unit 31 has a second connecting portion 311 and a second bent portion 312, with a second groove 313 between them. The first bent portion 22 is located within the second groove 313, and the second bent portion 312 is located within the first groove 23. This arrangement creates an interlocking structure between the nested first bent portions 22 and 312, ensuring the reliability of the blocking unit 31 fixed to the blocking end 201. Furthermore, the first groove 23 and second groove 313 facilitate on-site construction and alignment.

[0071] The shielding unit 31 is provided with a first fixing groove 315, and the sealing unit 32 is detachably disposed within the first fixing groove 315. This arrangement provides the first fixing groove 315 with a mounting position for the sealing unit 32, facilitating its installation. The detachable design allows the sealing unit 32 to be replaced individually after aging or damage, without needing to replace the entire shielding mechanism 30, thus reducing maintenance costs.

[0072] Specifically, the sealing unit 32 includes a fixing section 321 and a sealing section 322. The cross-sectional area of ​​the fixing section 321 along the first direction is larger than that of the sealing section 322 along the first direction. The first fixing groove 315 includes a first receiving portion 3151 and a first opening 3152. The fixing section 321 is disposed within the first receiving portion 3151. The first opening 3152 communicates with the first receiving portion 3151. The cross-sectional area of ​​the first opening 3152 along the first direction is smaller than that of the first receiving portion 3151 along the first direction. The sealing section 322 passes through the first opening 3152. This arrangement, through the size difference between the first receiving portion 3151 and the first opening 3152, can limit the fixing section 321, thereby achieving a firm fixation of the sealing unit 32 and preventing the sealing unit 32 from falling out of the first fixing groove 315. At the same time, it avoids the connection between the sealing unit 32 and the shielding unit 31 being affected by factors such as temperature, improving the stability and reliability of the connection between the sealing unit 32 and the shielding unit 31. The sealing section 322 passes through the first opening 3152 and abuts against the adjacent photovoltaic tile 10, achieving an effective seal.

[0073] In some embodiments, the sealing unit 32 has a certain compression and rebound space, which can adapt to different gaps between two adjacent photovoltaic tiles 10.

[0074] In some embodiments, the first fixing groove 315 is disposed at the end of the shielding unit 31 away from the connection with the frame 20, which can reduce the size of the sealing unit 32 and reduce the sealing cost.

[0075] Furthermore, the shielding end 201 has a first connecting hole 24, and the shielding unit 31 has a second connecting hole 314. The shielding mechanism 30 also includes a locking member 33, which is disposed within the first connecting hole 24 and the second connecting hole 314 to fix the shielding unit 31 and the shielding end 201. With this configuration, the first bending portion 22 and the second bending portion 312 can pre-fix the shielding unit 31, and the locking member 33 can ensure the stability and reliability of the connection between the shielding end 201 and the shielding unit 31, improve the wind and earthquake resistance of the shielding unit 31, and prevent the shielding unit 31 from falling off the shielding end 201.

[0076] In some embodiments, the blocking unit 31 is a baffle.

[0077] In some embodiments, the first connecting hole 24 or the second connecting hole 314 is a threaded hole.

[0078] In some embodiments, the locking element 33 is a screw, which may be made of metal materials such as aluminum alloy, stainless steel, carbon steel, copper, galvanized steel, etc., or of materials such as carbon fiber composite materials.

[0079] See Figure 4 and Figure 5 In another embodiment, the sealing unit 32 is detachably connected to the frame 20. The sealing unit 32 is provided with a third connecting hole 3221, and one end of the locking member 33 passes through the third connecting hole 3221. With this configuration, the locking member 33 fixes the three structures of the shielding unit 31, the frame 20 and the sealing unit 32, reducing the assembly difficulty, reducing the number of parts used, and ensuring the stability of the three structures.

[0080] See Figure 5 A second fixing groove 25 is provided on the frame 20, positioned between the shading unit 31 and the connecting end 202. The sealing unit 32 is detachably mounted within the second fixing groove 25. This arrangement provides the second fixing groove 25 with a suitable mounting position for the sealing unit 32, facilitating its installation. The detachable design allows the sealing unit 32 to be replaced individually after aging or damage, eliminating the need to replace the entire shading mechanism 30 or the entire frame 20, thus reducing maintenance costs. Furthermore, the placement of the second fixing groove 25 addresses the unsightly exposed sealing unit 32, further improving the overall aesthetic uniformity of the photovoltaic power generation device.

[0081] Furthermore, the sealing unit 32 includes a fixing section 321 and a sealing section 322, wherein the cross-sectional area of ​​the fixing section 321 along the first direction is larger than the cross-sectional area of ​​the sealing section 322 along the first direction. The second fixing groove 25 includes a second receiving portion 251 and a second opening 252. The fixing section 321 is disposed within the second receiving portion 251. The second opening 252 communicates with the second receiving portion 251, and the cross-sectional area of ​​the second opening 252 along the first direction is smaller than the cross-sectional area of ​​the second receiving portion 251 along the first direction. The sealing section 322 passes through the second opening 252. With this arrangement, the fixing section 321 can be limited by the size difference between the second receiving portion 251 and the second opening 252, thereby achieving a firm fixation of the sealing unit 32 and preventing the sealing unit 32 from falling out of the second fixing groove 25. At the same time, it avoids the connection between the sealing unit 32 and the frame 20 being affected by factors such as temperature, improving the stability and reliability of the connection between the sealing unit 32 and the frame 20. The sealing section 322 passes through the second opening 252 and abuts against the adjacent photovoltaic tile 10, achieving an effective seal.

[0082] Specifically, the shortest distance between two adjacent photovoltaic tiles 10 along the first direction is H, and the dimension of the shading unit 31 along the first direction is L, where 0.8H≤L≤H. This setting avoids the shading unit 31 being too small to effectively shade the connection end 202, ensuring that the shading unit 31 can fully cover and shade the support 40 and the tile strip 50 below, while also avoiding the shading unit 31 being too large to interfere with the photovoltaic tiles 10, thus ensuring the normal installation of the shading unit 31.

[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
