[0041] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0042] The following is for reference. Figures 1-5The present application describes a photovoltaic system 1 and a connecting bracket 10 according to an embodiment of the present application.

[0043] like Figure 1 and Figure 2 As shown, the photovoltaic system 1 includes multiple photovoltaic modules 20, each including a frame 21 and a laminate 22. Two adjacent photovoltaic modules 20 are connected by a connecting bracket 10, forming a largely integral structure. This ensures that when one photovoltaic module 20 is subjected to pressure deformation, the relative deformation between the frame 21 of that photovoltaic module 20 and the frame 21 of the adjacent photovoltaic module 20 is small, facilitating the passage of the cleaning robot.

[0044] like Figure 1 As shown, the frame 21 includes side beams 211 and middle beams 212. The side beams 211 of different photovoltaic modules 20 are all arranged along the second direction X, and the middle beams 212 of adjacent photovoltaic modules 20 are arranged opposite each other.

[0045] This application also provides a connecting bracket 10.

[0046] The connecting bracket 10 is a clamping component used to clamp the frame 21 of the adjacent photovoltaic module 20.

[0047] like Figure 3 As shown, the connecting bracket 10 in this embodiment includes: a connecting part 13, a first clamping part 11, and a second clamping part 12.

[0048] like Figures 3-5 As shown, the connecting part 13 can be a block or plate-shaped structure with sufficient rigidity and strength, serving as a main support and connecting hub.

[0049] like Figure 3 As shown, the connecting part 13 has two opposing sides in the first direction W, namely a first side 131 and a second side 132. The first side 131 and the second side 132 can be the side with the smaller area of ​​the connecting part 13.

[0050] The connecting part 13 and the first clamping part 11 can be rigidly connected by means of integral bending, welding or other methods.

[0051] The connecting part 13 and the second clamping part 12 can be rigidly connected by means of integral bending, welding or other methods.

[0052] like Figures 3-5 As shown, the second clamping part 12 and the first clamping part 11 are arranged opposite to each other along the first direction W. The first clamping part 11, the connecting part 13 and the second clamping part 12 are connected sequentially, and the connecting bracket 10 is generally shaped like a "C". In this way, the upper and lower flanges of the frame 21 of the photovoltaic module 20 can be clamped between the second clamping part 12 and the first clamping part 11.

[0053] like Figure 3 and Figure 4 As shown, at least a portion of the first clamping part 11 is at a vertical distance from the first direction W to the second side surface 132 that is less than the vertical distance from the first side surface 131 to the second side surface 132.

[0054] In other words, at least a portion of the first clamping part 11 is inclined from one end near the first side 131 toward the other end toward the second clamping part 12.

[0055] That is, the vertical distance from the portion of the first clamping part 11 that contacts or clamps the photovoltaic module 20 to the second side 132 in its natural state, without deformation of the connecting bracket 10 due to installation, is less than the vertical distance between the first side 131 and the second side 132 of the connecting part 13 itself. The effective clamping portion of the first clamping part 11 is inclined or protrudes towards the second clamping part 12, extending beyond the plane where the first side 131 is located.

[0056] like Figure 3 and Figure 4 As shown, at least a portion of the second clamping part 12 is at a vertical distance from the first side surface 131 along the first direction W to the first side surface 131, which is less than the vertical distance from the second side surface 132 to the first side surface 131.

[0057] In other words, at least a portion of the second clamping portion 12 is inclined from one end near the second side 132 toward the other end toward the first clamping portion 11.

[0058] That is, the vertical distance from the portion of the second clamping part 12 that contacts or clamps the photovoltaic module 20 to the first side surface 131 in its natural state, without deformation of the connecting bracket 10 due to installation, is less than the vertical distance between the second side surface 132 of the connecting part 13 and the first side surface 131. The effective clamping portion of the second clamping part 12 is inclined or protrudes towards the first clamping part 11, extending beyond the plane where the second side surface 132 is located.

[0059] like Figures 3-5 As shown, the first clamping part 11 and the second clamping part 12 present a spatial layout in which they face each other and form a clamping space between them for accommodating and clamping the photovoltaic module 20.

[0060] like Figures 3-5 As shown, the effective clamping areas of the first clamping part 11 and the second clamping part 12 are both located within the space defined by the first side surface 131 and the second side surface 132 along the first direction W, and they extend inward relative to each other. This results in the minimum distance between the effective clamping portions of the first clamping part 11 and the second clamping part 12 along the first direction W being less than the height of the clamped portion of the photovoltaic module 20, thereby enabling the connection and clamping functions of the connecting bracket 10.

[0061] When installing the connecting bracket 10 of the present application embodiment onto the photovoltaic module 20, no special tooling is required. Simply move the clamping space defined between the first clamping part 11 and the second clamping part 12 toward the frame 21 of the adjacent photovoltaic module 20, and push the connecting bracket 10 so that the frame 21 drives the first clamping part 11 and the second clamping part 12 to elastically deform in opposite directions, thereby achieving the assembly of the connecting bracket 10.

[0062] When unloading the connecting bracket 10 of this application embodiment, no special tooling is required. Simply force the first clamping part 11 to elastically deform in the direction away from the second clamping part 12, and push the frame 21 to move in the direction away from the connecting part 13, so as to unload the connecting bracket 10.

[0063] According to the connecting bracket 10 provided in the embodiments of this application, by designing the first clamping part 11 and the second clamping part 12 which are relatively inclined, one-step installation can be achieved without special tooling, resulting in high construction efficiency and low cost.

[0064] Correspondingly, the photovoltaic system 1 provided in the embodiments of this application can be installed in one step without special tooling by adopting the above-mentioned connecting bracket 10, which has high construction efficiency and low cost.

[0065] In this embodiment, at least a portion of the first clamping part 11 is perpendicularly distanced from the first direction W to the second side surface 132 to a distance less than the perpendicular distance from the first side surface 131 to the second side surface 132.

[0066] The first clamping part 11 can be at least one of the following structural forms:

[0067] Firstly, the first clamping part 11 can be segmented.

[0068] In this embodiment, such as Figure 1 and Figure 3 As shown, the first clamping part 11 may include a mating section 111 and limiting sections 112 located on both sides of the mating section 111 and distributed along a second direction. That is, the mating section 111 is located in the central region of the first clamping part 11, the limiting sections 112 are located at both ends of the mating section 111, and the mating section 111 and the limiting sections 112 are distributed along the second direction. The second direction X may intersect with the first direction W.

[0069] In other words, the first clamping part 11 may include a first limiting segment 112, a mating segment 111 and a second limiting segment 112 connected sequentially along the second direction X.

[0070] Among them, such as Figure 1 and Figure 3As shown, the mating section 111 mates with the middle beam 212 of the frame 21, and the limiting section 112 mates with the side beam 211 of the frame 21. That is, the space between the mating section 111 and the second clamping part 12 accommodates the middle beam 212, and the space between the limiting section 112 and the second clamping part 12 accommodates the side beam 211.

[0071] like Figure 1 and Figure 3 As shown, the mating section 111 can be connected to the first side surface 131, and the whole is planar.

[0072] like Figure 1 and Figure 3 As shown, the limiting segment 112 can be connected to the first side 131 and the mating segment 111.

[0073] The mating section 111 and the limiting section 112 of the first clamping part 11 can be rigidly connected by means of integral cutting, welding or other methods.

[0074] The limiting segment 112 may include two regions extending in different directions, namely the first region 113 and the second region 114.

[0075] like Figure 3 As shown, the first region 113 is connected to the first side surface 131 and the mating section 111, and can be a planar whole, and the first region 113 and the mating section 111 can maintain a coplanar relationship.

[0076] like Figure 3 As shown, the second region 114 can be connected to the end of the first region 113 that is away from the first side surface 131, and is inclined towards the second clamping part 12 in the direction away from the first region 113. A continuous bending structure can be formed between the second region 114 and the first side surface 131, and the included angle α between the second region 114 and the first side surface 131 can be controlled within the range of 10°-30°, for example, 18° or 20°. That is, this included angle α can ensure that the second region 114 has sufficient elastic deformation capacity and structural rigidity. The inclined second region 114 can form a gripper pointing towards the interior of the clamping space.

[0077] When the connecting bracket 10 of this embodiment is installed on the photovoltaic module 20, the clamping space defined between the first clamping part 11 and the second clamping part 12 is directed toward the frame 21 of the adjacent photovoltaic module 20. The connecting bracket 10 is pushed so that the frame 21 drives the second region 114 of the first clamping part 11 to elastically deform in the direction away from the second clamping part 12. Under the action of the reset elastic force, the first clamping part 11 automatically clamps the frame 21, which can realize tool-free installation.

[0078] like Figure 3As shown, after the connecting bracket 10 is installed on the photovoltaic module 20, the second region 114 cooperates with the side beam 211 of the frame 21, that is, the second region 114 clamps the side beam 211.

[0079] like Figure 1 and Figure 3 As shown, the second region 114 may include an effective clamping region. The minimum distance between this region and the second side 132 is less than the vertical distance between the first side 131 and the second side 132. This geometric layout allows the inclined inner wall surface of the second region 114 to make progressive contact with the surface of the frame 21, thereby enabling the first clamping part 11 to achieve the constraint function of the photovoltaic module 20 along the first direction W.

[0080] like Figure 1 and Figure 3 As shown, the inclined inner wall of the second region 114 forms a sloped locking on the frame 21. The component force along the third direction Y generated by the inclined angle α presses the photovoltaic module 20 against the connecting part 13, thereby enabling the first clamping part 11 to achieve the constraint function along the third direction Y. Wherein, the third direction Y intersects with the first direction W.

[0081] When unloading the connecting bracket 10 of this application embodiment, there is no need to rely on special tooling. The second region 114 of the first clamping part 11 is elastically deformed in the direction away from the second clamping part 12, and the frame 21 is pushed in the direction away from the connecting part 13, so that the connecting bracket 10 can be unloaded.

[0082] The first region 113 and the second region 114 of the limiting segment 112 can be rigidly connected by means of integral bending, welding or other methods.

[0083] In some embodiments, such as Figure 1 and Figure 3 As shown, a gap 115 can be formed between the mating segment 111 and the limiting segment 112. The gap 115 extends from the end of the second region 114 away from the first region 113 to the connection point across the first region 113 and the second region 114.

[0084] like Figure 1 As shown, the notch 115 creates a physical separation between the mating section 111 and the limiting section 112. When the connecting bracket 10 is installed on the photovoltaic module 20, this structural design allows the mating section 111 and the intermediate beam 212, and the limiting section 112 and the side beam 211 to form independent mating relationships, and the gap space formed by the notch 111 can compensate for the installation position deviation of the module.

[0085] The notch 115 allows the first region 113 to generate controllable elastic deflection with the bottom of the notch 115 as the pivot point, increasing the elastic stroke of the second region 114, so that the first clamping part 11 can generate a greater clamping force.

[0086] The notch 115 forms a certain physical isolation between the mating section 111 and the limiting section 112. When the limiting section 112 undergoes elastic deformation, it can prevent it from contacting and rubbing against the mating section 111.

[0087] When disassembling the connecting bracket 10 of this application embodiment, the notch 115 can increase the elastic deformation stroke of the second region 114, making it easier for the operator to apply force to make the second region 114 elastically deform in the direction away from the second clamping part 12, thereby reducing the difficulty of disassembling the connecting bracket 10.

[0088] Notch 115 can be processed by cutting, grinding, etc.

[0089] Secondly, the first clamping part 11 can be a single piece.

[0090] The first clamping part 11 can be undivided and extend from one end to the other along the second direction X to form a whole.

[0091] In this embodiment, the first clamping part 11 may include a first part and a second part. The first part may be connected to the first side surface 131 and is generally planar. The second part may be connected to the end of the first part that is away from the first side surface 131 and is inclined towards the second clamping part 12 in the direction away from the first part.

[0092] The second part and the first side 131 can form a continuously bent structure, and the included angle α between the second part and the first side 131 can be controlled within the range of 10°-30°. The inclined second part can form a gripper pointing towards the inside of the clamping space.

[0093] After the connecting bracket 10 is installed on the photovoltaic module 20, the second part cooperates with the side beam 211 and the middle beam 212 of the frame 21, that is, the second part clamps the side beam 211 and the middle beam 212.

[0094] The first clamping part 11 can be formed by integral bending or welding, which is relatively simple to process.

[0095] The clamping area of ​​the first clamping part 11 includes the side beam 211 and the middle beam 212, which has a greater clamping force and a stronger constraint on the photovoltaic module 20.

[0096] In this embodiment, at least a portion of the second clamping portion 12 is perpendicularly distanced from the first side surface 131 along the first direction W to the first side surface 131, which is less than the perpendicularly distance from the second side surface 132 to the first side surface 131.

[0097] The second clamping part 12 can be at least one of the following structural forms:

[0098] Firstly, the second clamping part 12 may include a main board body 121 and a protrusion 122, and at least a portion of the main board body 121 and at least a portion of the protrusion 122 are closer to the first side side 131 than the second side side 132.

[0099] like Figures 3-5 As shown, the main board 121 is connected to the second side 132 and can be planar in shape. The main board 121 can be tilted towards the first clamping part 11 from the direction away from the connecting part 13. A continuous bending structure can be formed between the main board 121 and the connecting part 13, and the included angle β between the main board 121 and the second side 132 can be controlled within the range of 85°-89°. That is, this included angle β can ensure that the main board 121 has sufficient elastic deformation capacity and structural rigidity. The tilted main board 121 can form a gripper pointing towards the interior of the clamping space.

[0100] like Figures 3-5 As shown, the protrusion 122 can be provided on the side of the main body 121 facing the first clamping part 11. When the connecting bracket 10 is connected to the photovoltaic module 20, the protrusion 122 has a constraining force on the frame 21 of the photovoltaic module 20 pointing towards the first clamping part 11 due to elastic deformation, which makes it easy for the connecting bracket 10 to clamp the photovoltaic module 20.

[0101] The second clamping part 12 applies a clamping force to the photovoltaic module 20, directed towards the first clamping part 11, through the inclined main body 121 and the protrusion 122 provided on the main body 121.

[0102] In some embodiments, such as Figures 3-5 As shown, the protrusion height of the protrusion 122 gradually increases along the direction close to the connecting part 13. For example, the side of the protrusion 122 away from the connecting part 13 can form a progressive tilt angle of 8°-30° relative to the plane of the main body 121, forming a guide slope.

[0103] Thus, when the connecting bracket 10 of this embodiment is installed on the photovoltaic module 20, the photovoltaic module 20 is gradually squeezed by the protrusion 122 instead of being suddenly blocked. The protrusion 122 can play an installation guiding role, making it easy to install the connection between the connecting bracket 10 and the photovoltaic module 20 in one step.

[0104] In some embodiments, such as Figure 4 As shown, the protruding end face 123 of the protrusion 122 facing the connecting part 13 is adapted to abut against the inner end face of the frame 21 of the photovoltaic module 20, and the end face of the protrusion 122 facing the connecting part 13 can form an angle of 70°-90° relative to the plane of the main body 121.

[0105] The distance from the protruding end face 123 to the connecting portion 13 in the connecting bracket 10 can be set as the width of the frame 21. Thus, when the connecting bracket 10 of this embodiment is installed on the photovoltaic module 20, the inner end face of the frame 21 abuts against the protruding end face 123. The protruding end face 123 restricts the displacement of the frame 21 along the third direction Y, allowing the second clamping portion 12 to constrain the photovoltaic module 20 along the third direction Y.

[0106] In some embodiments, such as Figure 4 As shown, the protrusion 122 includes multiple groups, and the distance between the protrusion 122 and the connecting part 13 is different for different groups.

[0107] The distances from different groups of protruding end faces 123 to the connecting portion 13 in a single connecting bracket 10 can be set to the widths of different models of frame 21 on the market. In this way, a single connecting bracket 10 contains multiple groups of protruding end faces 123 with different distances to the connecting portion 13. Different groups of protruding end faces 123 can match the inner end faces of frame 21 of different sizes, so that a single connecting bracket 10 can be adapted to photovoltaic modules 20 using frame 21 of different sizes.

[0108] In a single connecting bracket 10, the distance from each set of protruding end faces 123 to the connecting portion 13 can be set to correspond to the width specifications of different models of frame 21. With this design, a single connecting bracket 10 can be adapted to photovoltaic modules 20 of various sizes, and can match the inner end faces of different specifications of frame 21 without changing the bracket, thus achieving universal installation.

[0109] Three sets of protrusions 122 with different spacing can be set: the distance from the first protrusion 122a to the connecting part 13 can be 10cm, the distance from the second protrusion 122b to the connecting part 13 can be 20cm, and the distance from the third protrusion 122c to the connecting part 13 can be 30cm. When the distance from the inner end face of the frame 21 to the edge of the frame 21 is 10cm, the first protrusion 122a can abut against the inner end face of the frame 21, and the second protrusion 122b and the third protrusion 122c can clamp the frame 21; when the distance from the inner end face of the frame 21 to the edge of the frame 21 is 20cm, the second protrusion 122b can abut against the inner end face of the frame 21, and the first protrusion 122a and the third protrusion 122c can clamp the frame 21; when the distance from the inner end face of the frame 21 to the edge of the frame 21 is 30cm, the third protrusion 122c can abut against the inner end face of the frame 21, and the first protrusion 122a and the second protrusion 122b can clamp the frame 21.

[0110] In some embodiments, such as Figure 5As shown, the protrusion 122 is formed by stamping a portion of the main body 121. This allows the protrusion 122 to be formed directly from the material of the main body 121 without introducing additional material, reducing the material usage and overall weight of the connecting bracket 10. Furthermore, the protrusion 122 has no weld seams or adhesive interfaces, eliminating the risk of peeling failure associated with traditional assembled protrusion structures.

[0111] Of course, protrusion 122 can also be formed in other ways, such as welding or bonding.

[0112] Secondly, the second clamping part 12 may include the main body 121 and the protrusion 122, and at least a portion of the protrusion 122 is closer to the first side 131 than the second side 132.

[0113] like Figures 3-5 As shown, the main board body 121 is connected to the second side 132 and can be a planar structure. The main board body 121 can have sufficient structural rigidity.

[0114] like Figures 3-5 As shown, the protrusion 122 can be provided on the side of the main body 121 facing the first clamping part 11. When the connecting bracket 10 is connected to the photovoltaic module 20, the protrusion 122 has a constraining force on the frame 21 of the photovoltaic module 20 pointing towards the first clamping part 11 due to elastic deformation, which makes it easy for the connecting bracket 10 to clamp the photovoltaic module 20.

[0115] The structure of protrusion 122 can be referred to the description of the foregoing embodiment.

[0116] The second clamping part 12 applies a clamping force to the photovoltaic module 20 directed towards the first clamping part 11 through the protrusion 122 provided on the main body 121.

[0117] Third, the second clamping part 12 can be an integral plate, which is inclined towards the first clamping part 11 in the direction away from the connecting part 13.

[0118] In this embodiment, the second clamping part 12 is connected to the second side surface 132 and can be planar in shape. A continuous bending structure can be formed between the second clamping part 12 and the connecting part 13, and the included angle β between the second clamping part 12 and the second side surface 132 can be controlled within the range of 85°-89°. That is, this included angle β can ensure that the second clamping part 12 has sufficient elastic deformation capacity and structural rigidity. The inclined second clamping parts 12 can form grippers pointing towards the interior of the clamping space.

[0119] The second clamping part 12 applies a clamping force to the photovoltaic module 20, directed towards the first clamping part 11, through the inclined main body 121.

[0120] For the second clamping part 12 with at least one of the above-mentioned structural forms, the second clamping part 12 achieves the function of constraining the photovoltaic module 20 through at least one of the main body 121, the protrusion 122 or the integral plate itself.

[0121] When the connecting bracket 10 of this application embodiment is installed on the photovoltaic module 20, the clamping space defined between the first clamping part 11 and the second clamping part 12 is directed toward the frame 21 of the adjacent photovoltaic module 20. The connecting bracket 10 is pushed so that the frame 21 drives the second clamping part 12 to elastically deform in a direction away from the first clamping part 11. Under the action of the reset elastic force, the second clamping part 12 automatically clamps the frame 21, which can realize tool-free installation.

[0122] When the connecting bracket 10 is unloaded, the second clamping part 12 returns to its natural state by relying on the material's elasticity.
