Description

Technical Field

[0001] The present application relates to the field of photovoltaic technology, and in particular to an installation structure and a photovoltaic component. Background Art

[0002] The frame, a key component of photovoltaic modules, protects the module edges, enhances module strength, and secures the modules. Conventional frames are constructed by opening holes in the frame and then fastening the frame profile to the mounting bracket using fasteners. Traditional frames are typically made of aluminum alloy. Composite materials are now becoming an attractive alternative to aluminum alloy due to their lightweight, high-strength, corrosion-resistant, and low-cost advantages.

[0003] However, when composite materials are used to manufacture frames, due to the structural characteristics of the composite materials themselves, if holes are opened on any side of the frame, the continuous fibers at the openings will be cut, the mechanical properties of the frame will be damaged, and the edges of the holes will become stress concentration points, which are prone to cracking along the fiber direction under load, resulting in failure of the connection and fixation, and the connection reliability between the frame and the socket will be seriously reduced; at the same time, based on the method of opening holes in the frame, after the frame and the socket are connected through the holes in the frame, the socket and the bracket need to be installed again, and the entire installation process is complicated, resulting in low overall installation efficiency of the photovoltaic components.

[0004] Therefore, in view of this, the present utility model is proposed. Utility Model Content

[0005] In response to the above technical problems, the purpose of this application is to propose an installation structure and a photovoltaic component to solve the technical problems of stress concentration caused by frame openings and complicated installation process in the prior art.

[0006] In a first aspect, the present application provides a mounting structure comprising a frame and a holder, wherein the frame comprises a main body, a first extension portion, and a second extension portion. The first extension portion comprises a first connecting section and a first snap-fit section, wherein the first connecting section is connected to the main body and protrudes from the main body in the transverse direction, and the first snap-fit section is connected to the first connecting section and extends in the vertical direction toward the second extension portion. The second extension portion comprises a second connecting section and a second snap-fit section, wherein the second connecting section is connected to the main body and protrudes from the main body in the transverse direction, and the second snap-fit section is connected to the second connecting section and extends in the vertical direction toward the first extension portion, and the second snap-fit section and the first snap-fit section are spaced apart in the vertical direction and staggered in the transverse direction to form a slide groove together with the main body.

[0009] In a further solution of the present application, the length of the first clamping section in the vertical direction is L1, and the distance between the first connecting section and the second connecting section in the vertical direction is h, where h≥L1≥h / 5.

[0010] In a further embodiment of the present application, the card holder further comprises a main body and a connecting portion, wherein the connecting portion is connected to the main body and the plug-in portion at both ends in the horizontal direction, respectively, and the plug-in portion forms a first limiting groove with the main body at one end in the vertical direction and a second limiting groove with the connecting portion at the other end. The first engaging section is disposed in the first limiting groove, and the second engaging section is disposed in the second limiting groove.

[0011] In a further embodiment of the present application, the width of one end of the plug-in portion that forms the first limiting groove with the main body in the transverse direction is greater than the width of one end of the plug-in portion that forms the second limiting groove with the connecting portion in the transverse direction.

[0012] In a further embodiment of the present application, a third limiting groove is provided on the second engaging section. The third limiting groove is configured to accommodate a portion of the engaging base, thereby limiting the position of the plug-in portion within the chute. When the engaging base is accommodated in the third limiting groove, the plug-in portion extends into the chute to a depth greater than 2 mm and less than 5 mm. Preferably, the plug-in portion extends into the chute to a depth of 3.5 mm.

[0013] In a further embodiment of the present application, the card holder further comprises a main body and a connecting portion, wherein the connecting portion is connected to the main body and the plug-in portion at both ends in the transverse direction, respectively. The frame further comprises a supporting portion, which is located in the transverse direction on the side of the second engaging section facing away from the slide groove and is connected to the second engaging section. The main body is provided with a recess, which is configured to receive the supporting portion after the plug-in portion is inserted into the slide groove, so that the main body is supported on the supporting portion.

[0014] In a further solution of the present application, the width of the support portion in the transverse direction is greater than the width of the first clamping section in the transverse direction and the width of the second clamping section in the transverse direction.

[0015] In a further solution of the present application, the support portion and the first clamping section are arranged flush with an end surface facing away from the sliding groove in the transverse direction.

[0016] In a further embodiment of the present application, the width of the support portion in the transverse direction is d, the width of the first clamping section in the transverse direction is W1, and the width of the second clamping section in the transverse direction is W2, wherein d=q*W1 or d=q*W2, and 1.1≤q≤2.

[0017] In a further embodiment of the present application, 1.0≤W1≤2.5mm; and / or, 1.0≤W2≤2.5mm.

[0018] In a further embodiment of the present application, the mounting structure further comprises a fastening assembly, comprising a fastener and a position limiting member.

[0019] In a second aspect, the present application provides a photovoltaic component, which includes a laminate and the above-mentioned mounting structure, wherein the laminate is mounted on the frame, and the vertical direction is parallel to the thickness direction of the laminate.

[0020] In summary, the mounting structure and photovoltaic component provided by this application have at least the following beneficial effects:

[0021] In the mounting structure of the present application, since the first and second extensions protrude from the main body and are surrounded by a sliding groove, this is equivalent to using the first and second extensions and the sliding groove formed by them on the outside of the main body to achieve a plug-in connection with the card holder. Compared with the method of providing an opening in the main body of the frame for connection, the present application not only does not weaken the strength of the main body of the frame or cause stress concentration problems, but instead increases the strength of the entire frame to a certain extent, thereby improving the overall connection reliability of the mounting structure. At the same time, since the second clamping section of the second extension is spaced apart from the first clamping section of the first extension in the vertical direction and offset in the horizontal direction, after the plug-in portion is inserted into the sliding groove formed by the first and second extensions, relative forces are generated between the first clamping section and the plug-in portion, and between the second clamping section and the plug-in portion, respectively, and the relative forces between the two are not on the same straight line, thereby avoiding stress concentration in the first clamping section and the second clamping section after assembly, thereby improving the stability of the fit between the frame and the card holder. In addition, based on the plug-in connection between the plug-in portion and the first extension portion and the second extension portion, when the plug-in portion is plugged into the slide groove, the plug-in portion is limited in the horizontal and vertical directions, so that the entire card holder will not move in the horizontal and vertical directions before being fixed to the part to be connected, thereby greatly improving the connection strength between the frame and the card holder, and during the entire installation process of the photovoltaic component, the installation is simple and the card holder will not fall off, thereby improving the installation efficiency and connection reliability.

[0043] Figure 1 This is a schematic diagram of the structure of the photovoltaic component provided in the embodiment of the present application. Figure 1 The photovoltaic component 1000 of the present application includes a mounting structure 100 and a laminate 200. The mounting structure 100 is used to fix the laminate 200 and to fix the laminate 200 to a member to be connected (such as a bracket, a roof, or the ground).

[0044] The laminate 200 may include a stacked arrangement of photovoltaic tempered glass, EVA film or PO film, photovoltaic cell strings, and a photovoltaic backsheet or photovoltaic backsheet glass, for photovoltaic power generation. Of course, the laminate 200 may also be composed of other structures, and this application does not specifically limit the specific structure of the laminate 200.

[0045] The mounting structure 100 may include a frame 10 and a holder 20. The laminate 200 may be pre-fixed (e.g., bonded) to the frame 10 to form a photovoltaic module together with the frame 10. The photovoltaic module may be connected to the holder 20 via the frame 10, and the holder 20 is used to connect to a component to be connected, thereby achieving fixed installation of the photovoltaic module.

[0046] Furthermore, to achieve connection between the holder 20 and the object to be connected, the mounting structure 100 may also include a fastening assembly 30, through which the holder 20 is connected to the object to be connected. Specifically, the fastening assembly 30 may include a fastener 31, a stopper 32, and a locking member 33. In an optional embodiment, the stopper 32 may be a washer-like structure, the fastener 31 may be a bolt, and the locking member 33 may be a nut.

[0047] Figure 2 A schematic diagram of the installation structure of a photovoltaic component provided in an embodiment of the present application is provided. Figure 3 This is a diagram of the installation status of the card holder and the frame of the installation structure provided in an embodiment of the present application.

[0048] Reference Figure 2 and Figure 3 The frame 10 includes a main body 11, a first extension portion 12 and a second extension portion 13. The first extension portion 12 and the second extension portion 13 are both arranged to protrude from the main body 11 along the horizontal direction W, and the first extension portion 12 and the second extension portion 13 are spaced apart in the vertical direction H to form a slide groove A together with the main body 11.

[0049] Specifically, the frame 10 can be a profile, and the body 11 can have multiple sides, which enclose a profile cavity G. The multiple sides include first sides spaced apart in the transverse direction W and second sides spaced apart in the vertical direction H. The first and second extensions 12, 13 are located outside the profile cavity G and protrude beyond the first side of the body 11. The first and second extensions 12, 13, together with corresponding portions of the first side, form a chute A. The first and second extensions 12, 13 can each be flush with the corresponding second side in the vertical direction H, or spaced apart from the corresponding second side in the vertical direction H.

[0050] It can be understood that the length of the first side in the vertical direction H may be greater than the length of the second side in the horizontal direction W. In this case, the first side can be called the long side and the second side can be called the short side. On the contrary, the length of the first side in the vertical direction H may also be less than the length of the second side in the horizontal direction W. In this case, the first side can be called the short side and the second side can be called the long side. Of course, the length of the first side in the vertical direction H may also be equal to the length of the second side in the horizontal direction W. This application does not make any specific restrictions on the lengths of the first side and the second side.

[0051] The first extension portion 12 includes a first connecting section 121 and a first clamping section 122. The first connecting section 121 is connected to the main body 11 and protrudes from the main body 11 in the horizontal direction W. The first clamping section 122 is connected to the first connecting section 121 and extends toward the second extension portion 13 in the vertical direction H so as to protrude from the first connecting section 121. That is, the first extension portion 12 is formed into a "┐"-shaped structure.

[0052] The second extension portion 13 includes a second connecting section 131 and a second clamping section 132. The second connecting section 131 is connected to the main body 11 and protrudes from the main body 11 in the horizontal direction W. The second clamping section 132 is connected to the second connecting section 131 and extends toward the first extension portion 12 in the vertical direction H so as to protrude from the second connecting section 131. That is, the second extension portion 13 is also formed into a "┘"-shaped structure.

[0053] The second clamping section 132 and the first clamping section 122 are spaced apart in the vertical direction H and staggered in the horizontal direction W to form a sliding groove A together with the first connecting section 121 , the second connecting section 131 and the body 11 .

[0054] The card holder 20 includes a plug-in portion 22, which is plugged into the frame 10 via the plug-in portion 22. When the plug-in portion 22 is inserted into the slide groove A of the frame 10, the two ends of the plug-in portion 22 in the vertical direction H are respectively located between the first clamping section 122 and the body 11 and between the second clamping section 132 and the body 11. At this time, the plug-in portion 22 can also move along the longitudinal direction L within the slide groove A to slide to the desired installation position. The vertical direction H is perpendicular to the light-receiving surface of the laminate 200, that is, the vertical direction H is parallel to the thickness direction of the laminate 200, and the plane enclosed by the longitudinal direction L and the transverse direction W is parallel to the light-receiving surface of the laminate 200. The longitudinal direction L is the extension direction of the slide groove A.

[0055] It can be understood that after the socket 20 is assembled with the frame 10, at least a portion of the plug-in portion 22 is accommodated in the slide groove A and is clamped to the first extension portion 12 and the second extension portion 13 to constrain the main body 11 in the horizontal direction W and the vertical direction H. At the same time, in order to ensure that the plug-in portion 22 can slide in the longitudinal direction L in the slide groove A, the height of the plug-in portion 22 in the vertical direction Z needs to be less than the depth of the slide groove A in the vertical direction Z. Specifically, the height of the plug-in portion 22 in the vertical direction Z is 2-5 mm smaller than the depth of the slide groove A in the vertical direction Z. It should be noted here that the "clamping" mentioned in this application can refer to a hugging connection or a mutually locking connection.

[0056] In the mounting structure 100 of the present application, since the first extension portion 12 and the second extension portion 13 protrude from the main body 11 and are surrounded by a slide groove A, it is equivalent to using the first extension portion 12 and the second extension portion 13 and the slide groove A surrounded by them on the outside of the main body 11 to achieve a plug-in connection with the card holder 20. Compared with the method of setting an opening on the main body 11 of the frame 10 for connection, the present application not only does not weaken the strength of the main body 11 of the frame 10 and cause stress concentration problems, but instead increases the strength of the entire frame 10 to a certain extent, thereby improving the overall connection reliability of the mounting structure 100. At the same time, since the second clamping section 132 of the second extension part 13 and the first clamping section 122 of the first extension part 12 are spaced and arranged opposite to each other in the vertical direction H and are staggered in the horizontal direction W, after the plug-in part 22 is inserted into the sliding groove A formed by the first extension part 12 and the second extension part 13, relative forces are respectively formed between the first clamping section 122 and the plug-in part 22, and between the second clamping section 132 and the plug-in part 22, and the relative forces of the two are not on the same straight line, thereby avoiding stress concentration in the first clamping section 122 and the second clamping section 132 after assembly, thereby improving the stability of the fit between the frame 10 and the card seat 20. In addition, based on the plug-in connection between the plug-in portion 22 and the first extension portion 12 and the second extension portion 13, when the plug-in portion 22 is plugged into the slide groove A, the plug-in portion 22 is limited in the horizontal direction W and the vertical direction H, so that before the holder 20 is fixed to the part to be connected, the entire holder 20 will not move in the horizontal direction W and the vertical direction H, thereby greatly improving the connection strength between the frame 10 and the holder 20, and during the entire installation process of the photovoltaic component 1000, the installation is simple and the holder 20 will not fall off, thereby improving the installation efficiency and connection reliability.

[0057] Figure 4 A three-dimensional diagram of the frame in the installation structure provided in an embodiment of the present application, Figure 5 for Figure 4 The main view of the border in .

[0058] Reference Figure 4 The distance between the center of the second engaging section 132 and the center of the first engaging section 122 in the horizontal direction W is z, the distance between the second engaging section 132 and the first engaging section 122 in the vertical direction H is b, and the distance between the first connecting section 121 and the second connecting section 131 in the vertical direction H is h. Then z = a*b, and 1 / 6 ≤ a ≤ 2 / 3, b < h. Specifically, a can be 1 / 6, 1 / 4, 1 / 3, 5 / 12, 1 / 2, 7 / 12, 2 / 3, etc. This configuration can avoid the problem of the card holder 20 shaking in the chute A due to an oversized chute A, and the problem of the card holder 20 having difficulty sliding relative to the chute A or even causing wear on the chute A due to an undersized chute A.

[0059] Reference Figure 4 and Figure 5 The frame 10 further includes a third extension portion 15 , which protrudes from the body 11 along the vertical direction H and together with the body 11 forms a slot F. The laminate 200 is installed in the slot G. Specifically, the slot G and the slide groove A can open toward the same side of the body 11 in the horizontal direction W, or can open toward both sides of the body 11 in the horizontal direction W.

[0060] In an optional embodiment, the first engaging section 122 is located between the third extension portion 15 and the second engaging section 132 in the vertical direction H, and the length L1 of the first engaging section 122 in the vertical direction H is greater than the length L2 of the second engaging section 132 in the vertical direction H. It is understandable that when the plug-in portion 22 of the holder 20 is inserted into the chute A, the second connecting section 131 of the second extension portion 13 supports the holder 20 during the sliding and installation process. Furthermore, since the length of the first engaging section 122 in the vertical direction H is greater than the length of the second engaging section 132 in the vertical direction H, the force-bearing contact surface between the first engaging section 122 and the plug-in portion 22 of the holder 20 can be significantly increased, thereby preventing the plug-in portion 22 of the holder 20 from falling out of the chute A, thereby improving the installation reliability of the photovoltaic module.

[0061] In an optional embodiment, the spacing between the first connecting segment 121 and the second connecting segment 131 in the vertical direction H is h, and the length L1 of the first engaging segment 122 in the vertical direction H satisfies the following relationship: h ≥ L1 ≥ h / 5. For example, the length L1 of the first engaging segment 122 in the vertical direction H can be h, h / 40, h / 20, 3h / 40, h / 10, h / 8, 3h / 20, 7h / 40, h / 5, etc. This configuration can avoid deformation after pultrusion caused by an excessively long first engaging segment 122, which can lead to breakage during use and thus affect the installation reliability of the photovoltaic module. It can also avoid the problem of the engaging bracket 20 easily sliding out of the slide slot A due to an undersized first engaging segment 122, which can cause the engaging bracket 20 to separate from the frame 10 and thus affect the installation reliability of the photovoltaic module.

[0062] Reference Figure 4 and Figure 5The second engaging section 132 is provided with a third limiting groove B3, which is configured to accommodate a portion of the card holder 20 to limit the position of the plug-in portion 22 within the chute A. That is, before the card holder 20 is engaged with the third limiting groove B3, the plug-in portion 22 can slide along the longitudinal direction L within the chute A until it is positioned at the third limiting groove B3 for installation. When the card holder 20 is partially engaged with the third limiting groove B3, the plug-in portion 22 cannot continue to slide along the longitudinal direction L within the chute A due to the action of the sidewalls of the third limiting groove B3, indicating that the slidable installation is in place. Conversely, if removal or adjustment of the installation position is required, the portion of the card holder 20 can be removed from the third limiting groove B3. At this time, the plug-in portion 22 can continue to slide along the longitudinal direction L within the chute A to be removed from the chute A or installed at another position within the chute A. Therefore, installation in place or release can be achieved based on the plug-in connection between the card holder 20 and the frame 10 and the cooperation and limitation of the third limiting groove B3. The installation method is simple, thereby greatly improving the installation efficiency.

[0063] When the card holder 20 is accommodated in the third limiting groove B3, the insertion portion 22 extends into the chute A to a depth of 2 mm to 5 mm. For example, the insertion portion 22 may extend into the chute A to a depth of 2 mm, 2.5 mm, 2.8 mm, 3 mm, 3.2 mm, 3.5 mm, 4 mm, 4.2 mm, 4.5 mm, 4.8 mm, 5 mm, etc. This configuration effectively prevents the insertion portion 22 from being dislodged from the chute A when excessive load is applied, while also significantly reducing the material used for the card holder 20 and the frame 10. Preferably, the insertion portion 22 extends into the chute A to a depth of 3.5 mm. Figure 6 This is a structural diagram of a card holder in the installation structure provided in an embodiment of the present application. Figure 7 This is another structural schematic diagram of the card holder in the installation structure provided in an embodiment of the present application.

[0064] Reference Figure 6 and Figure 7 The card holder 20 also includes a main body 21 and a connecting portion 23. The two ends of the connecting portion 23 in the horizontal direction W are respectively connected to the main body 21 and the plug-in portion 22, that is, the connecting portion 23 is located between the main body 21 and the plug-in portion 22 in the horizontal direction W and is connected to the main body 21 and the plug-in portion 22. In addition, one end of the plug-in portion 22 in the vertical direction H forms a first limiting groove B1 with the main body 21, and the other end forms a second limiting groove B2 with the connecting portion 23. The first clamping section 122 is set in the first limiting groove B1, and the second clamping section 132 is set in the second limiting groove B2. Among them, the main body 21 can be provided with a mounting hole T. The card holder 20 cooperates with the fastening assembly 30 through the mounting hole T to achieve the connection between the card holder 20 and the part to be connected, thereby achieving fixed installation of the photovoltaic module.

[0065] Based on the arrangement of the first limiting groove B1 and the second limiting groove B2, when the plug-in portion 22 of the card holder 20 is plugged into the frame 10 through the slide groove A, the first extension portion 12 of the frame 10 is also plugged into the card holder 20 through the first limiting groove B1, and the second extension portion 13 is plugged into the card holder 20 through the second limiting groove B2, thereby achieving a mutual plug-in connection between the card holder 20 and the frame 10, improving the alignment and matching accuracy between the two. At the same time, under the action of the first limiting groove B1 and the second limiting groove B2, a multi-point plug-in connection between the card holder 20 and the frame 10 is also achieved, thereby improving the installation reliability of the photovoltaic module. Moreover, when the plug-in portion 22 of the card holder 20 slides in the slide groove A, the first extension portion 12 and the second extension portion 13 of the frame 10 can also slide along the first limiting groove B1 and the second limiting groove B2, respectively. Therefore, based on the guiding effect of three different directions, the stability during sliding is greatly improved.

[0066] In an optional embodiment, the width of the end of the plug-in portion 22 and the main body 21 forming the first limiting groove B1 in the horizontal direction W is greater than the width of the end of the plug-in portion 22 and the connecting portion 23 forming the second limiting groove B2 in the horizontal direction W, that is, the end of the plug-in portion 22 close to the first extension portion 12 (such as Figure 6-7 The width of the upper end shown in FIG. 1 in the transverse direction W is greater than the width of the end close to the second extension portion 13 (as shown in FIG. Figure 6-7 Such a configuration can improve the ability of the plug-in portion 22 to withstand loads. When the plug-in portion 22 is impacted by a load, the deformation of the upper end of the plug-in portion 22 can be effectively reduced, thereby improving the stability of the card holder 20.

[0067] Continue to refer to Figures 2 to 5 The frame 10 further includes a support portion 14, which is located on the side of the second clamping section 132 away from the sliding groove A in the horizontal direction W and is connected to the second clamping section 132. Figure 6 and Figure 7 The main body 21 is provided with a notch E, which is configured to accommodate the support portion 14 after the plug-in portion 22 is inserted into the slide groove A, so that the main body 21 is supported on the support portion 14.

[0068] In this embodiment, based on the cooperation between the notch E and the support portion 14, after the plug-in portion 22 is inserted into the chute A, the notch E can accommodate the support portion 14, so that the support portion 14 can provide surface support for the main body 21. This can disperse the pressure of the card holder 20 on the frame 10, thereby reducing the pressure of the plug-in portion 22 on the bottom wall of the chute A (the second connecting section 131 of the second extension portion 13 is the bottom wall of the chute A), thereby avoiding the problem of stress concentration on the bottom wall of the chute A. At the same time, during the process of connecting the card holder 20 to the part to be connected, based on the cooperation between the chute A and the plug-in portion 22, and the cooperation between the notch E and the support portion 14, the plug-in portion 22 is unlikely to rotate or can only rotate slightly within the chute A, thereby helping to improve installation efficiency.

[0069] In an optional embodiment, the width of the support portion 14 in the transverse direction W is greater than the width of the first clamping section 122 in the transverse direction W and the width of the second clamping section 132 in the transverse direction W. It should be noted that, generally, the width of the first clamping section 122 in the transverse direction W can be the same as the width of the second clamping section 132 in the transverse direction W. Of course, in certain specific special cases, the width of the first clamping section 122 in the transverse direction W and the width of the second clamping section 132 in the transverse direction W can also be different. The width of the support portion 14 in the transverse direction W is set to be greater than the width of the first clamping section 122 in the transverse direction W and the width of the second clamping section 132 in the transverse direction W in order to ensure that there is a larger force-bearing contact surface between the support portion 14 and the main body 21, thereby dispersing the force on the support portion 14 and avoiding the problem of stress concentration in the support portion 14, thereby improving the installation reliability of the photovoltaic module.

[0070] Furthermore, the support portion 14 is flush with the end surface of the first engaging section 122 facing away from the chute A in the transverse direction W. In other words, the projection of the end surface of the support portion 14 facing away from the chute A in the transverse direction W and the end surface of the first engaging section 122 facing away from the chute A in the transverse direction W in the vertical direction Z coincides.

[0071] Since the frame 10 can be formed by a composite material pultrusion process, the end faces of the support portion 14 and the first clamping section 122 facing away from the chute A in the horizontal direction W are arranged flush, so that the traction mechanism can simultaneously clamp the first clamping section 122 and the surface of the support portion 14 in the horizontal direction W for traction, thereby ensuring that the surface clamped by the traction mechanism is subjected to balanced force, so that the chute A can be formed according to the preset shape, thereby improving the yield rate of the frame 10. This is because, if the end faces of the support portion 14 and the first clamping section 122 facing away from the chute A in the horizontal direction W are not arranged flush (that is, the two are not coplanar), the traction mechanism will not be convenient to clamp them. After clamping, the end faces of the support portion 14 and the first clamping section 122 facing away from the chute A in the horizontal direction W will inevitably be subjected to uneven force, which will cause the first clamping section 122 to shrink and deform the chute A, thereby affecting the spatial shape of the chute A.

[0072] In an alternative embodiment, the width of the support portion 14 in the transverse direction W is d, the width of the first engaging section 122 in the transverse direction W is W1, and the width of the second engaging section 132 in the transverse direction W is W2. Here, d = q * W1 or d = q * W2, and 1.1 ≤ q ≤ 2. For example, q can be 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, etc.

[0073] When the width of the support portion 14 and the width of the first clamping section 122 or the second clamping section 132 are set in the above-mentioned relationship, it can be ensured that the support portion 14 does not exceed the second clamping section 132 in the horizontal direction W, and it can also be ensured that the strength of the support portion 14, the first clamping section 122 and the second clamping section 132 can meet the use requirements. This can prevent the first clamping section 122 and the second clamping section 132 from breaking due to too low strength and the support portion 14 from having stress concentration problems, and can also reduce the material cost of the overall production of the frame 10.

[0074] Furthermore, 1.0≤W1≤2.5mm. For example, W1 can be specifically 1.0mm, 1.2mm, 1.3mm, 1.5mm, 1.8mm, 2.0mm, 2.2mm, 2.3mm, 2.5mm, etc. Similarly, 1.0≤W2≤2.5mm. For example, W2 can be specifically 1.0mm, 1.2mm, 1.3mm, 1.5mm, 1.8mm, 2.0mm, 2.2mm, 2.3mm, 2.5mm, etc.

[0075] Reference Figure 6 The mounting hole T can be a threaded hole. In this case, the fastener 31 can be installed directly from bottom to top and cooperate with the mounting hole T thread for fastening connection. This not only can omit the locking member 33 (ie, the nut), but also improves the installation efficiency.

[0076] Reference Figure 7 The main body 21 is provided with a first groove C1 and a second groove C2. The bottom wall of the second groove C2 is provided with a mounting hole T for mounting a fastener 31. The first groove C1 is used to cooperate with the limiting member 32 to limit the limiting member 32 in the circumferential direction, thereby preventing the fastener 31 from rotating when the locking member 33 engages with the fastener 31. Therefore, the arrangement of the first groove C1 and the second groove C2 not only ensures the positioning and installation of the fastening assembly 30, improving installation efficiency, but also reduces the weight of the card holder 20.

[0077] Figure 8 This is another structural diagram of the installation structure of the photovoltaic component provided in the embodiment of the present application, Figure 9 Based Figure 7 Schematic diagram of the structure of the card holder of the installation structure.

[0078] Reference Figure 8 and Figure 9 The frame 10 of the mounting structure of the present application includes a body 11, a second extension 13, and a third extension 15. The second extension 13 protrudes from the body 11 in the horizontal direction W and forms a sliding groove A together with the body 11. The third extension 15 protrudes from the body 11 in the vertical direction H and forms a locking groove F together with the body 11. The laminate 200 is installed in the locking groove G.

[0079] After the plug-in portion 22 of the card holder 20 is inserted into the chute A formed by the second extension portion 13 and the body 11, the two end surfaces of the plug-in portion 22 in the horizontal direction W can respectively abut against the body 11 and the second extension portion 13, so that when the card holder 20 is connected to the part to be connected, the plug-in portion 22 will not rotate in the chute A, thereby helping to improve the installation efficiency. At the same time, compared with the above embodiment ( Figures 1 to 7 Compared with the frame 10 in the embodiment, the first extension portion 12 located between the second extension portion 13 and the third extension portion 15 in the vertical direction H of the frame 10 is cancelled in the present embodiment, which not only makes the structure of the frame 10 simple and easy to form, but also greatly saves materials and reduces the cost of the frame 10.

[0080] In this embodiment, the main body 11 of the frame 10 is surrounded by a profile cavity G, and the second extension portion 13 includes a second connecting section 131 and a second clamping section 132. The second connecting section 131 is connected to the main body 11 and protrudes from the main body 11 in the horizontal direction W. The second clamping section 132 is connected to the second connecting section 131 and protrudes from the second connecting section 131 in the vertical direction H, that is, the second extension portion 13 is formed into a "┘"-shaped structure.

[0081] The wall thickness L3 of the body 11 and the width L2 of the second engaging section 132 in the horizontal direction W (also referred to as the thickness of the second engaging section 132) must satisfy the following relationship: 1.1*L3≤L2≤1.5*L3. This is because a thinner second engaging section 132 reduces the installation reliability of the photovoltaic module; while a thicker second engaging section 132 increases the cost of the frame 10. Preferably, the wall thickness L3 of the body 11 is 2 mm, and the width L2 of the second engaging section 132 in the horizontal direction W is 3 mm.

[0082] Continue to refer to Figure 8 and Figure 9 The card holder 20 further includes a main body 21 and a connecting portion 23. The connecting portion 23 is connected to the main body 21 and the plug-in portion 22 at both ends in the transverse direction W. That is, the connecting portion 23 is located between the main body 21 and the plug-in portion 22 in the transverse direction W and is connected to the main body 21 and the plug-in portion 22. Furthermore, the plug-in portion 22, the connecting portion 23, and the main body 21 together form a second limiting groove B2, and the second engaging section 132 is disposed in the second limiting groove B2.

[0083] Based on the setting of the second limiting groove B2, when the plug-in portion 22 of the card holder 20 is plugged into the frame 10 through the slide groove A, the second extension portion 13 of the frame 10 is plugged into the card holder 20 through the second limiting groove B2, thereby realizing the mutual plug-in connection between the card holder 20 and the frame 10, thereby improving the alignment and matching accuracy between the two.

[0084] Continue to refer to Figure 8 and Figure 9 The frame 10 further includes a support portion 14, which is located on a side of the second engaging section 132 facing away from the slide groove A in the transverse direction W and is connected to the second engaging section 132. The main body 21 is provided with a notch E, which is configured to receive the support portion 14 after the insertion portion 22 is inserted into the slide groove A, so that the main body 21 is supported on the support portion 14.

[0085] Continue to refer to Figure 8 and Figure 9 The main body 21 is provided with a first groove C1 and a second groove C2. The bottom wall of the second groove C2 is provided with a mounting hole T (not shown). The mounting hole T is used to install the fastener 31. The first groove C1 is used to cooperate with the limit member 32 to limit the limit member 32 in the circumferential direction, thereby preventing the fastener 31 from rotating when the locking member 33 engages with the fastener 31. Therefore, the provision of the first groove C1 and the second groove C2 not only allows the fastener assembly 30 to be positioned and installed, improving installation efficiency, but also reduces the weight of the card holder 20.
