[0096] An embodiment of the present application provides a photovoltaic component, which includes a color steel tile 10, a clamp 20 installed on the color steel tile 10, and a photovoltaic assembly 30 clamped and fixed by the clamp 20.

[0097] like Figure 1 and Figure 2 As shown, the color steel tile 10 includes a male rib 101, a bending portion 106, a bottom plate 105, at least one corner portion 104 and a female rib 102 distributed along a first direction X. In a possible design, as shown in FIG. Figure 2As shown, the male rib 101 and the female rib 102 have only one corner portion 104. In this case, the male rib 101 and the corner portion 104, and the corner portion 104 and the female rib 102 are connected by a bottom plate 105. In another possible design, as shown in FIG. Figure 1 As shown, the male rib 101 and the female rib 102 are provided with at least two angular portions 104. At this time, the male rib 101 and the angular portions 104, the adjacent angular portions 104, and the angular portions 104 and the female rib 102 are all connected through the bottom plate 105. The bending portion 106 includes a first bending section 106A extending along the first direction X and a second bending section 106B extending obliquely. One end of the first bending section 106A is connected to the male rib 101 or the female rib 102, and the other end is connected to the second bending section 106B. The end of the second bending section 106B away from the first bending section 106A is connected to the bottom plate 105, that is, the male rib 101 and the bottom plate 105, and the female rib 102 and the bottom plate 105 are connected through the bending portion 106. A plurality of color steel tiles 10 are distributed along the first direction X, and the male ribs 101 of the color steel tiles 10 are fixedly connected with the female ribs 102 of the adjacent color steel tiles 10 by locking edges to form a Figure 3 The round edge locking structure 103 is shown.

[0098] The clamp 20 is clamped on the Wanchi locking structure 103 , and in the first direction X, both ends of the photovoltaic assembly 30 are clamped and fixed by the clamp 20 to achieve the installation of the photovoltaic assembly 30 on the color steel tile 10 .

[0099] The structure of the photovoltaic module 30 is as follows Figure 3 As shown, it includes a laminate 301 and a back frame 302 installed on the backlight side of the laminate 301. The light-facing side of the laminate 301 and the surface of the back frame 302 facing away from the laminate 301 are respectively abutted against the clamp 20 to achieve clamping and fixing of the photovoltaic component 30 by the clamp 20.

[0100] like Figure 3 and Figure 4As shown, the back frame 302 comprises a first part 302A, a second part 302B and a third part 302C, the first part 302A and the third part 302C both extend along the thickness direction Z of the photovoltaic module 30, the second part 302B extends along the first direction X, and both ends of the second part 302B are respectively connected to the first part 302A and the third part 302C, that is, the first part 302A, the second part 302B and the third part 302C form a U-shaped structure, and the second part 302B is bonded and fixed to the backlight surface of the laminate 301. Providing a back frame 302 on the backlight surface of the laminate 301 can improve the structural strength of the edge of the laminate 301 and reduce the risk of damage to the edge of the laminate 301 due to stress concentration when the clamp 20 clamps the edge of the laminate 301. The back frame 302 is located on the side of the laminate 301 away from the sunlight, which reduces the shielding of the back frame 302 on the light-facing surface of the laminate 301, which is beneficial to improving the photoelectric conversion efficiency and output power of the laminate 301.

[0101] The back frame 302 is bonded to the laminate 301 by a connecting adhesive. Specifically, the connecting adhesive can be a structural adhesive or a solid adhesive such as a double-sided adhesive tape.

[0102] like Figure 4 As shown, the back frame 302 may further include a first bending portion 302A2 and a second bending portion 302C2, wherein the first bending portion 302A2 is located on a side of the first portion 302A away from the second portion 302B, and the first bending portion 302A2 extends toward the third portion 302C along the first direction X, and the second bending portion 302C2 is located on a side of the third portion 302C away from the second portion 302B, and the second bending portion 302C2 extends toward the first portion 302A along the first direction X, The first portion 302A, the second portion 302B and the third portion 302C form a cavity 302D, the first bent portion 302A2 and the second bent portion 302C2 block a portion of the cavity 302D in the thickness direction Z of the photovoltaic module 30, and the gap between the first bent portion 302A2 and the second bent portion 302C2 forms a first opening 302D1, and the cavity 302D is connected to the outside through the first opening 302D1 along the thickness direction Z of the photovoltaic module 30. When the clamp 20 clamps the photovoltaic module 30, the first bent portion 302A2 and the second bent portion 302C2 are used to abut against the clamp 20 in the thickness direction Z of the photovoltaic module 30, which can increase the contact area between the back frame 302 and the clamp 20, thereby reducing the risk of damage to the back frame 302 or the clamp 20 due to local force on the back frame 302 and the clamp 20, which is conducive to extending the service life of the back frame 302 and the clamp 20.

[0103] like Figure 5As shown, a portion of the first portion 302A is bent and deformed toward the third portion 302C to form a first recessed portion 302A1. When the laminate 301 is subjected to a downward force along the thickness direction Z of the photovoltaic component 30, the back frame 302 can be elastically deformed at the first recessed portion 302A1 to reduce the force of the back frame 302 on the laminate 301, thereby reducing the risk of edge damage to the laminate 301; and / or, a portion of the second portion 302B is bent and deformed toward the first portion 302A to form a second recessed portion 302B1. When the laminate 301 is subjected to a downward force along the thickness direction Z of the photovoltaic component 30, the back frame 302 can be elastically deformed at the second recessed portion 302B1 to reduce the force of the back frame 302 on the laminate 301, thereby reducing the risk of edge damage to the laminate 301.

[0104] like Figure 5 As shown, a portion of the second portion 302B can be bent and deformed in a direction away from the laminate 301 to form a third recessed portion 302C1. The third recessed portion 302C1 can increase the volume of the structural adhesive between the back frame 302 and the laminate 301, thereby improving the bonding stability between the back frame 302 and the laminate 301.

[0105] like Figure 3 As shown, the clamp 20 includes a clamping component 1 for clamping the Maruchi lock edge structure 103 and a cover plate 2 installed on the clamping component 1, the clamping component 1 includes a first clamping portion 121, the cover plate 2 includes a second clamping portion 22, and in the thickness direction Z of the photovoltaic component 30, the second clamping portion 22 is in contact with the light-facing surface of the laminate 301, wherein the contact between the second clamping portion 22 and the light-facing surface of the laminate 301 can be direct contact or indirect contact, and the first clamping portion 121 is in contact with the surface of the back frame 302 on the side away from the laminate 301, that is, the clamp 20 clamps and fixes the photovoltaic component 30 through the first clamping portion 121 and the second clamping portion 22.

[0106] like Figure 3 As shown, a first limiting portion 121B is provided on the first clamping portion 121, and the first limiting portion 121B extends toward the laminate 301 along the thickness direction Z of the photovoltaic component 30, and along the first direction X, the first limiting portion 121B is located on the side of the back frame 302 away from the round lock structure 103, that is, along the first direction X, the first limiting portion 121B is located on the side of the back frame 302 close to the center of the laminate 301, and the first limiting portion 121B can abut against the back frame 302 in the first direction X to limit the relative movement of the photovoltaic component 30 and the clamp 20 in the first direction X, thereby reducing the risk of the photovoltaic component 30 detaching from the clamp 20 along the first direction X, so as to improve the connection stability between the clamp 20 and the photovoltaic component 30.

[0107] The first clamping portion 121 is also provided with a second limiting portion 121A extending along the thickness direction Z of the photovoltaic module 30. In one embodiment, as shown in FIG. Figures 9 to 11 As shown, along the first direction X, the second limiting portion 121A is located on the side of the back frame 302 facing the round edge locking structure 103, and the second limiting portion 121A abuts against the first portion 302A in the first direction X; in another embodiment, as shown in FIG. Figure 3 As shown, a part of the second limiting portion 121A is located at the first opening 302D1, and the second limiting portion 121A extends into the cavity 302D along the thickness direction Z of the photovoltaic assembly 30, and the second limiting portion 121A abuts against the first portion 302A or the third portion 302C in the first direction X. During the installation of the photovoltaic assembly 30 and the clamp 20, the photovoltaic assembly 30 needs to be placed on the first clamping portion 121 first, and then the cover plate 2 is covered on the light-facing surface of the photovoltaic assembly 30. The second limiting portion 121A is set to limit the moving distance of the photovoltaic assembly 30 in the first direction X, reducing the risk that the cover plate 2 cannot be installed normally due to the small distance between the photovoltaic assembly 30 and the Maruchi locking structure 103, thereby helping to reduce the difficulty of installing the cover plate 2 on the clamping assembly 1.

[0108] like Figure 3 and Figure 6 As shown, when a part of the second limiting portion extends into the cavity 302D, a fifth bending portion 121A1 is provided at one end of the second limiting portion 121A away from the first clamping portion 121, and the fifth bending portion 121A1 extends obliquely. When the laminate 301 is subjected to an upward force along the thickness direction Z of the photovoltaic component 30, at least a part of the back frame 302 will move or deform in a direction away from the first clamping portion 121 driven by the laminate 301. At this time, the fifth bending portion 121A1 can abut against the first bending portion 302A2 or the second bending portion 302C2 to reduce the risk of the second limiting portion 121A detaching from the cavity 302D, thereby improving the connection stability between the first clamping portion 121 and the back frame 302.

[0109] Furthermore, if Figure 5 As shown, a third bending portion 302A3 may be provided on the side of the first bending portion 302A2 away from the first portion 302A, the third bending portion 302A3 bends and extends into the cavity 302D, and the fifth bending portion 121A1 may be clamped with the third bending portion 302A3 in the first direction X to enhance the connection stability between the first clamping portion 121 and the back frame 302; and / or a fourth bending portion 302C3 may be provided on the side of the second bending portion 302C2 away from the third portion 302C, the fourth bending portion 302C3 bends and extends into the cavity 302D, and the fifth bending portion 121A1 may be clamped with the fourth bending portion 302C3 in the first direction X to enhance the connection stability between the first clamping portion 121 and the back frame 302.

[0110] like Figure 3 As shown, the clamp 20 includes a first clamp 11 and a second clamp 12 which are arranged opposite to each other along a first direction X. The first clamp 11 and the second clamp 12 are both provided with a first clamping portion 121, and the first clamp 11 and the second clamp 12 are both installed with a cover plate 2, so that the clamp 20 can clamp and fix the photovoltaic assembly 30 on both sides in the first direction X, thereby facilitating the reduction of the spacing between adjacent photovoltaic assemblies 30 in the first direction X, so as to increase the number of photovoltaic assemblies 30 to be set. The first clamp 11 and the second clamp 12, the cover plate 2 and the first clamp 11, and the cover plate 2 and the second clamp 12 are all fixedly connected by a fastening assembly 3. Specifically, the fastening assembly 3 includes a first fastening assembly 31 and a second fastening assembly 32. The first fastening assembly 31 is used to lock and fix the first clamp 11 and the second clamp 12, and the second fastening assembly 32 is used to lock and fix the cover plate 2 and the first clamp 11, and the cover plate 2 and the second clamp 12.

[0111] The structures of the first clamping member 11 and the second clamping member 12 are basically the same. Taking the second clamping member 12 as an example, Figure 3 and Figure 6 As shown, the first clamping member 11 and the second clamping member 12 are both provided with a first clamping portion 121 extending along the first direction X, and along the first direction X, a connecting portion 12D extending along the thickness direction Z of the photovoltaic component 30 is provided on the side of the first clamping portion 121 away from the photovoltaic component 30, and along the thickness direction Z of the photovoltaic component 30, a third clamping portion 124 is provided on the side of the connecting portion 12D away from the first clamping portion 121, and the third clamping portions 124 on the first clamping member 11 and the second clamping member 12 are surrounded by In the first accommodating space for accommodating the Wanchi lock edge structure 103, in the thickness direction Z of the photovoltaic component 30, a second mounting portion 12E extending along the thickness direction Z of the photovoltaic component 30 is provided on the side of the third clamping portion 124 away from the first clamping portion 121, and the second mounting portion 12E on the first clamping member 11 is directly opposite to the second mounting portion 12E on the second clamping member 12 along the first direction X and is fixedly connected by the first fastening component 31 to realize the installation and fixation of the first clamping member 11 and the second clamping member 12.

[0112] like Figure 3 As shown, the second mounting portion 12E on the first clamping member 11 is provided with a limiting protrusion, which protrudes toward the second clamping member 12 along the first direction X, and the second mounting portion 12E on the second clamping member 12 is provided with a limiting groove, which is recessed away from the first clamping member 11 along the first direction X. After the first clamping member 11 and the second clamping member 12 are locked and fixed by the first fastening assembly 31, at least part of the limiting protrusion can extend into the limiting groove and abut against the side wall of the limiting groove to increase the accuracy of the relative position of the first clamping member 11 and the second clamping member 12.

[0113] In one possible design, the first fastening component 31 is a combination structure of a nut-spring washer-bolt; in another possible design, the first fastening component 31 is a combination structure of a nut-self-locking nut for locking and fixing to reduce the number of parts and reduce the cost of the clamp 20.

[0114] like Figure 3 and Figure 6 As shown, the contour shape of the third clamping portion 124 is an arc shape, so that the contour shape of the third clamping portion 124 matches the contour shape of the round-shaped locking structure 103, so as to increase the contact area between the third clamping portion 124 and the round-shaped locking structure 103, thereby facilitating the improvement of the clamping force of the third clamping portion 124 on the round-shaped locking structure 103.

[0115] The matching structures of the cover plate 2 on the first clamping member 11 and the second clamping member 12 are the same. For the convenience of description, the matching between the cover plate 2 and the clamping assembly 1 is described in detail below by taking the second clamping member 12 as an example.

[0116] like Figure 6 As shown, the cover plate 2 includes a first mounting portion 21, and along the first direction X, the first mounting portion 21 is arranged on the side of the second clamping portion 22 away from the photovoltaic component 30, the first mounting portion 21 is fixedly connected to the clamping component 1, and the first mounting portion 21 extends obliquely along the second direction T, so that the distance between the first clamping portion 121 and the second clamping portion 22 in the thickness direction Z of the photovoltaic component 30 is smaller than the distance between the first mounting portion 21 and the second clamping portion 22 in the thickness direction Z of the photovoltaic component 30.

[0117] The first mounting portion 21 extends obliquely along the second direction T, so that the cover plate 2 is obliquely mounted on the clamping assembly 1. During the process of locking and fixing the cover plate 2 and the clamping assembly 1, the operating space can be increased, thereby reducing the difficulty of installing the cover plate 2 and the clamping assembly 1, which is beneficial to shortening the installation period of the clamp 20; at the same time, the first mounting portion 21 extends obliquely along the second direction T, and the force applied by the second clamping portion 22 to the laminate 301 can generate a component force along the thickness direction Z of the photovoltaic component 30 and along the first direction X, thereby increasing the clamping force of the first clamping portion 121 and the second clamping portion 22 on the photovoltaic component 30, so as to enhance the clamping effect of the clamp 20 on the photovoltaic component 30, thereby enhancing the connection stability between the photovoltaic component 30 and the clamp 20; in addition , the cover plate 2 is installed at an angle, so that the height of the second clamping space is reduced, that is, the distance between the photovoltaic assembly 30 and the color steel tile 10 in the thickness direction Z of the photovoltaic assembly 30 is reduced. When the photovoltaic assembly 30 is subjected to a downward force in the thickness direction Z of the photovoltaic assembly 30, the photovoltaic assembly 30 can abut against the color steel tile 10, so that the contact area between the photovoltaic assembly 30 and the color steel tile 10 is increased, thereby increasing the supporting force of the color steel tile 10 on the photovoltaic assembly 30, and reducing the deformation degree of the photovoltaic assembly 30. During the installation of the photovoltaic assembly 30, the risk of the photovoltaic assembly 30 being damaged due to a large degree of deformation caused by workers stepping on the assembly is reduced, thereby improving the installation yield of the photovoltaic component and being conducive to improving the anti-trampling performance and working stability of the photovoltaic component. In the present application, by reducing the setting height of the second clamping space in the thickness direction Z of the photovoltaic assembly 30, the photovoltaic assembly 30 can be kept intact for 1 hour under the condition that the worker stands on one foot and the force is 120kg. It can be seen that the inclined installation of the cover plate 2 can greatly improve the anti-trampling performance of the photovoltaic component.

[0118] The angle between the second direction T and the first direction X is α1, 20°≤α1≤30°, and α1 can be 20°, 20.5°, 21°, 21.5°, 22°, 22.5°, 23°, 23.5°, 24°, 24.5°, 25°, 25.5°, 26°, 26.5°, 27°, 27.5°, 28°, 28.5°, 29°, 29.5°, 30°, etc.

[0119] If the angle between the second direction T and the first direction X is small, for example, α1<20°, the operating space during the installation of the cover plate 2 is small, and the installation difficulty is large; if the angle between the second direction T and the first direction X is large, for example, α1>30°, the overall height of the cover plate 2 will be increased, and the total height of the clamp 20 will be increased. Therefore, 20°≤α1≤30° can reduce the installation difficulty of the cover plate 2 while reducing the total height of the clamp 20.

[0120] like Figure 8 As shown, the cover plate 2 includes a third limiting portion 23, such as Figure 7 As shown, a limiting fitting portion 122 is provided on the second clamping member 12, and the third limiting portion 23 and the limiting fitting portion 122 are distributed along the first direction X. The third limiting portion 23 and the limiting fitting portion 122 both extend obliquely along the third direction K. In the thickness direction Z of the photovoltaic component 30 and the first direction X, the third limiting portion 23 is used to abut against the limiting fitting portion 122.

[0121] The third limiting portion 23 and the limiting matching portion 122 both extend along the third direction K, and the third limiting portion 23 and the limiting matching portion 122 abut against each other, so that there is a combined force acting between the third limiting portion 23 and the limiting matching portion 122 along a direction perpendicular to the third direction K, that is, there are component forces acting along the first direction X and along the thickness direction Z of the photovoltaic component 30, which reduces the risk of relative movement between the cover plate 2 and the clamping component 1 along the first direction X and along the thickness direction Z of the photovoltaic component 30, thereby improving the connection stability between the cover plate 2 and the clamping component 1. When the photovoltaic group is subjected to the force in the thickness direction Z of the photovoltaic component 30 and is bent and deformed in the direction away from the first clamping portion 121, the cover plate 2 will swing in the direction away from the first clamping portion 121 following the photovoltaic component 30, and the third limiting portion 23 swings synchronously, and the third limiting portion 23 abuts against the limiting matching portion 122, so that the limiting matching portion 122 swings synchronously under the drive of the third limiting portion 23, thereby driving the first clamping portion 121 to swing synchronously following the cover plate 2; similarly, when the photovoltaic component 30 is subjected to the force along the thickness direction Z of the photovoltaic component 30 and is bent and deformed toward the first clamping portion 121, the first clamping portion 121 swings in the direction away from the cover plate 2 following the photovoltaic component 30, and the limiting matching portion 122 swings synchronously, and the third limiting portion 23 abuts against the limiting matching portion 122, so that the third limiting portion 23 swings synchronously under the drive of the limiting matching portion 122, thereby driving the cover plate 2 to swing synchronously following the first clamping portion 121. Therefore, a third limiting portion 23 and a limiting matching portion 122 extending and abutting along the third direction K are provided, so that the cover plate 2 and the first clamping portion 121 can move synchronously with the deformation of the photovoltaic component 30, thereby reducing the risk of a large change in the distance between the first clamping portion 121 and the second clamping portion 22 in the thickness direction Z of the photovoltaic component 30, thereby improving the firmness of the clamp 20 clamping the photovoltaic component 30, so as to improve the structural stability and working stability of the photovoltaic component, and help to extend the service life of the photovoltaic component.

[0122] The angle between the third direction K and the first direction X is α2, 55°≤α2≤70°, and α2 can be 55°, 56°, 57°, 58°, 59°, 60°, 61°, 62°, 63°, 64°, 65°, 66°, 67°, 68°, 69°, 70°, etc.

[0123] If α2<55°, the force component generated by the third limit portion 23 and the limit matching portion 122 along the thickness direction Z of the photovoltaic module 30 is small, and if α2>70°, the force component generated by the third limit portion 23 and the limit matching portion 122 along the first direction X is small. Therefore, 55°≤α2≤70° can simultaneously improve the forces generated by the third limit portion 23 and the limit matching portion 122 along the first direction X and along the thickness direction Z of the photovoltaic module 30, thereby improving the stability of the synchronous movement of the cover plate 2 and the first clamping portion 121. 55°≤α2≤70° is reduced by 5° compared with the prior art, which can further facilitate the installation of the cover plate 2.

[0124] like Figure 8 As shown, the third limiting portion 23 includes a first abutting surface 231, and the limiting matching portion 122 includes a second abutting surface 122A. In the thickness direction Z and the first direction X of the photovoltaic component 30, the first abutting surface 231 is used to abut with the second abutting surface 122A; the matching height of the first abutting surface 231 and the second abutting surface 122A in the thickness direction Z of the photovoltaic component 30 is H, 1.1mm≤H≤3.5mm, and H can be 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, etc.

[0125] If the matching height between the first abutting surface 231 and the second abutting surface 122A is small, for example, H < 1.1 mm, the reliability of the matching between the third limiting portion 23 and the limiting matching portion 122 is poor, and there is a risk of failure of the matching between the third limiting portion 23 and the limiting matching portion 122; if the matching height between the first abutting surface 231 and the second abutting surface 122A is large, for example, H > 3.5 mm, it will increase the difficulty of installing and removing the cover plate 2 and the clamping assembly 1. Therefore, 1.1 mm ≤ H ≤ 3.5 mm, which improves the reliability of the matching between the third limiting portion 23 and the limiting matching portion 122, and reduces the difficulty of installing and removing the cover plate 2 and the clamping assembly 1.

[0126] like Figure 7 As shown, the first clamping portion 121 is provided with a first extension portion 123 extending vertically or obliquely toward the laminate 301 , and the limiting fitting portion 122 is provided at one end of the first extension portion 123 away from the first clamping portion 121 to increase the setting height of the limiting fitting portion 122 .

[0127] like Figure 7As shown, the clamping assembly 1 further includes a second extension portion 125 and a third extension portion 126. The third extension portion 126 and the third clamping portion 124 are arranged opposite to each other along the first direction X. The two ends of the second extension portion 125 are respectively connected to the third clamping portion 124 and the third extension portion 126. The third clamping portion 124, the second extension portion 125 and the third extension portion 126 form a clamping groove 127. Figure 8 As shown, the cover plate 2 is provided with a clamping portion 24. Along the second direction T, the clamping portion 24 is located on the side of the first mounting portion 21 away from the laminate 301, and at least part of the clamping portion 24 is located in the clamping groove 127; Figure 8 As shown, the clamping portion 24 includes a first inclined wall 241 extending obliquely along the third direction K. Figure 7 As shown, the engaging groove 127 includes a second inclined wall 127A extending obliquely along the third direction K. In the thickness direction Z and the first direction X of the photovoltaic component 30 , the first inclined wall 241 is used to abut against the second inclined wall 127A.

[0128] The first inclined wall 241 and the second inclined wall 127A both extend along the third direction K. When the third limiting portion 23 abuts against the limiting matching portion 122, the first inclined wall 241 abuts against the second inclined wall 127A. The limiting matching portion 122 can limit the movement of the cover plate 2 in the first direction X in the direction away from the photovoltaic component 30, and the second inclined wall 127A can limit the movement of the cover plate 2 in the first direction X in the direction close to the photovoltaic component 30, thereby improving the connection stability between the cover plate 2 and the clamping component 1; at the same time, the third limiting portion 23 and the limiting matching portion 122 both extend along the third direction K. When the cover plate 2 and the clamping component 1 are connected, the first inclined wall 241 and the second inclined wall 127A are connected. During the installation process, it is necessary to first abut the third limiting portion 23 with the limiting matching portion 122, and then drive the cover plate 2 to move along the third direction K in the direction close to the first clamping portion 121. The first inclined wall 241 and the second inclined wall 127A both extend along the third direction K, thereby reducing the risk of interference between the first inclined wall 241 and the second inclined wall 127A during the movement of the cover plate 2 along the third direction K, thereby improving the smoothness of the movement of the cover plate 2, which is beneficial to improving the stability of the connection between the cover plate 2 and the clamping assembly 1, and at the same time, it is beneficial to reduce the size of the clamping groove 127 in the first direction X, thereby improving the structural strength of the clamping groove 127.

[0129] Among them, the thickness of the clamping portion 24 in the second direction T is smaller than the width of the clamping groove 127 in the second direction T. During the installation of the cover plate 2, the clamping portion 24 can be rotated at a small angle in the clamping groove 127 to increase the installation space of the cover plate 2, thereby reducing the difficulty of installing the cover plate 2.

[0130] like Figure 3As shown, the first mounting portion 21 is fixedly connected to the clamping assembly 1 via a second fastening assembly 32. The second fastening assembly 32 may be a matching structure of a bolt-spring washer-nut, or a matching structure of a bolt-self-locking nut.

[0131] like Figure 7 As shown, the clamping assembly 1 also includes a fourth extension portion 128. Along the first direction X, the fourth extension portion 128 is located between the third clamping portion 124 and the first extension portion 123. One end of the fourth extension portion 128 is connected to the third clamping portion 124, and the other end of the fourth extension portion 128 extends obliquely away from the cover plate 2. The gap between the fourth extension portion 128 and the first extension portion 123 is used to accommodate a portion of the fastening assembly 3.

[0132] In one possible design, the fourth extension portion 128 can abut against the side wall of the second fastening assembly 32 to limit the rotation of the second fastening assembly 32 around its own axis, thereby facilitating the connection stability and reliability between the cover plate 2 and the clamping assembly 1; in another possible design, such as Figure 7 As shown, a fourth limiting portion 12C is provided on the third clamping portion 124 and / or the fourth extending portion 128 , and the fourth limiting portion 12C can abut against the side wall of the second fastening component 32 to limit the rotation of the second fastening component 32 around its own axis.

[0133] In one possible design, Figure 7 As shown, the end of the fourth extension portion 128 facing away from the cover plate 2 is connected to the first clamping portion 121. At this time, the fourth extension portion 128 can support the first clamping portion 121, the connecting portion 12D and the third clamping portion 124, thereby improving the structural strength of the first clamping member 11 and the second clamping member 12, so as to extend the service life of the clamp 20; in another possible design, such as Figures 9 to 11 As shown, there is a preset gap between the end of the fourth extension portion 128 away from the cover plate 2 and the first clamping portion 121 to reduce the size of the fourth extension portion 128, thereby facilitating the reduction of material cost and overall weight of the clamp 20.

[0134] In one possible design, Figure 7 As shown, the clamping assembly 1 includes a supporting portion 129, both ends of which are respectively connected to the first extension portion 123 and the fourth extension portion 128, and the supporting portion 129 is used to abut against the fastening assembly 3 to limit the movement of the fastening assembly 3 in the direction away from the cover plate 2, thereby reducing the difficulty of installing the cover plate 2, so as to shorten the installation period of the clamp 20; at the same time, the supporting portion 129 can support the first extension portion 123, reducing the risk of the first extension portion 123 being deformed or even damaged by external force, which is beneficial to extending the service life of the clamp 20.

[0135] In another possible design, Figures 9 to 11 As shown, the clamping assembly 1 includes a fifth extension portion 12A and a sixth extension portion 12B, one end of the fifth extension portion 12A is connected to the first extension portion 123, and the other end of the fifth extension portion 12A extends toward a direction close to the fourth extension portion 128, one end of the sixth extension portion 12B is connected to the fourth extension portion 128, and the other end of the fourth extension portion 128 extends toward a direction close to the first extension portion 123, and the fifth extension portion 12A and the sixth extension portion 12B are both used to abut against the fastening assembly 3 to limit the movement of the fastening assembly 3 in a direction away from the cover plate 2; the gap between the fifth extension portion 12A and the sixth extension portion 12B forms a second opening.

[0136] A second opening exists between the fifth extension portion 12A and the sixth extension portion 12B, which reduces the size of the fifth extension portion 12A and the sixth extension portion 12B, thereby helping to reduce the overall weight of the clamp 20. In addition, the second opening increases the installation space of the second fastening assembly 32, thereby reducing the difficulty of inserting the second fastening assembly 32 into the first clamp 11 and the second clamp 12.

[0137] In any of the above embodiments, the second clamping portion 22 may be in direct contact with the light-facing surface of the laminate 301; or, a rubber strip 4 is provided on the second clamping portion 22, and the second clamping portion 22 and the light-facing surface of the laminate 301 are in indirect contact via the rubber strip 4, that is, the photovoltaic module 30 and the second clamping portion 22 are in flexible contact, thereby reducing the risk of the photovoltaic module 30 being damaged by the second clamping portion 22.

[0138] When the second clamping portion 22 is in indirect contact with the light-facing surface of the laminate 301 through the adhesive strip 4, as shown in FIG. Figure 6 and Figure 8 As shown, the second clamping portion 22 is provided with a mounting groove 25, and the mounting groove 25 has a third opening 251. Along the thickness direction Z of the photovoltaic module 30, the mounting groove 25 is connected to the outside through the third opening 251, as shown in FIG. Figure 6 As shown, a third mounting portion 41 is provided on the rubber strip 4, and the third mounting portion 41 can extend into the mounting groove 25 through the third opening 251, wherein the contour shape of the third mounting portion 41 is arrow-shaped, so that the third mounting portion 41 can abut against the side wall of the mounting groove 25 in the thickness direction Z of the photovoltaic module 30, thereby reducing the risk of the rubber strip 4 falling off the second clamping portion 22, thereby improving the connection stability between the rubber strip 4 and the second clamping portion 22.

[0139] like Figure 8As shown, in the thickness direction Z of the photovoltaic component 30, along the direction from the photovoltaic component 30 to the second clamping portion 22, the width dimension of the third opening 251 gradually decreases, that is, in the process of inserting the third mounting portion 41 into the mounting groove 25, the side wall of the third opening 251 can guide the third mounting portion 41, thereby reducing the difficulty of inserting the third mounting portion 41.

[0140] The surface of the rubber strip 4 that is used to abut against the light-facing surface of the laminate 301 can extend horizontally along the first direction X, or can extend obliquely in the direction close to the photovoltaic module 30. When the surface of the rubber strip 4 that is used to abut against the light-facing surface of the laminate 301 extends obliquely, in the first direction X, along the direction from the edge of the photovoltaic module 30 to the center of the photovoltaic module 30, the thickness of the rubber strip 4 gradually increases, and the angle between the oblique direction and the first direction X is 3°~7°, specifically 3°, 3.5°, 4°, 4.5°, 5°, 5.5°, 6°, 6.5°, 7°, etc. When the photovoltaic module 30 is pressed down along the thickness direction Z of the photovoltaic module 30, the contact area between the rubber strip 4 and the laminate 301 can be increased, thereby increasing the clamping force of the clamp 20 on the photovoltaic module 30. At the same time, the surface shape of the rubber strip 4 matches the deformed shape of the photovoltaic module 30 when it is pressed down, which can further improve the compression resistance and anti-trampling performance of the photovoltaic module 30.

[0141] In one embodiment, in a direction perpendicular to the first direction X and the thickness direction Z of the photovoltaic component 30, both ends of the rubber strip 4 can extend to about 2 mm outside the clamp 20 to reduce the force exerted by the edge of the clamp 20 on the photovoltaic component 30, thereby reducing the risk of damage to the photovoltaic component 30 at the edge of the clamp 20 due to stress concentration when the photovoltaic component 30 is subjected to a downward force along the thickness direction Z of the photovoltaic component 30, thereby improving the compression resistance and anti-trampling performance of the photovoltaic component 30 at the edge of the clamp 20.

[0142] In another embodiment, pads can also be arranged on both sides of the clamp 20 in a direction perpendicular to the first direction X and the thickness direction Z of the photovoltaic component 30. The pads are located on the side of the photovoltaic component 30 facing away from the sunlight. When the photovoltaic component 30 is pressed down and deformed, the pads can support the photovoltaic component 30 to reduce the deformation degree of the photovoltaic component 30 at the edge of the clamp 20, thereby improving the compression resistance and anti-trampling performance of the photovoltaic component 30 at the edge of the clamp 20.

[0143] In any of the above embodiments, along the thickness direction Z of the photovoltaic component 30, the side of the first clamping portion 121 facing away from the photovoltaic component 30 abuts against the first bending section 106A of the color-coated steel tile 10, so that the color-coated steel tile 10 can support the clamp 20, thereby reducing the risk of damage to the clamp 20 or the photovoltaic component 30 caused by the clamp 20 bending and deforming downward along the thickness direction Z of the photovoltaic component 30, thereby helping to extend the service life of the clamp 20 and the photovoltaic component 30, and further helping to improve the working stability and reliability of the photovoltaic component. Among them, in one possible design, the wall on the first clamping portion 121 used to abut against the first bending segment 106A is a flat surface extending horizontally along the first direction X, so as to increase the contact area between the first clamping portion 121 and the first bending segment 106A, enhance the supporting effect of the first bending segment 106A on the clamp 20, and help to disperse the force between the first clamping portion 121 and the first bending segment 106A, thereby reducing the risk of deformation and damage of the first clamping portion 121 or the first bending segment 106A due to large local force; in another possible design, the first A portion of the wall on a clamping portion 121 that is used to abut against the first bending section 106A is bent and deformed in a direction close to the photovoltaic component 30, so that there is a recessed section on the first clamping portion 121 that is recessed upward along the thickness direction Z of the photovoltaic component 30. When the photovoltaic component 30 is subjected to an upward force along the thickness direction Z of the photovoltaic component 30 (such as wind blowing), the upward recessed section will increase the difficulty of the first clamping portion 121 to bend and deform upward, thereby reducing the risk of the clamp 20 bending and deforming upward, and further improving the stability of the connection between the clamp 20 and the color-coated steel tile 10.

[0144] In summary, the following is an example of the steps for installing the photovoltaic components provided in the embodiments of the present application:
