Description

Technical Field

[0001] The present invention generally relates to a mounting assembly for a photovoltaic panel, and more particularly to a mounting assembly for a flexible photovoltaic panel. Background Art

[0002] A flexible photovoltaic panel may include a bottom plate made of a flexible material and a photoelectric element layer formed by amorphous silicon tiled on the bottom plate and encapsulated with resin. The flexible photovoltaic panel can be easily bent into a curved surface or other irregular shapes for flexible installation, so as to make full use of solar energy and convert it into electric energy.

[0003] Currently, flexible photovoltaic panels are usually fixed to a bearing structure for mounting a photovoltaic panel, such as the roof and outer wall of a building, etc., by means of gluing. However, it is not easy to disassemble and maintain the flexible photovoltaic panel by gluing. Moreover, when the flexible photovoltaic panel is glued to the bearing structure, the spacing between the flexible photovoltaic panel and the bearing structure is often small. On the one hand, it is not conducive to the heat dissipation of the flexible photovoltaic panel, and even may cause the back surface of the flexible photovoltaic panel facing the bearing structure to be burned and damaged. On the other hand, if the bearing structure has poor drainage, it will also cause the flexible photovoltaic panel to be soaked in water, thereby affecting its service life. Summary of the Invention

[0004] The object of the present invention is to solve the problems existing in the above-mentioned prior art and propose an improved mounting assembly for a photovoltaic panel.

[0005] To this end, the present invention provides a mounting assembly for a photovoltaic panel, the mounting assembly being adapted to mount the photovoltaic panel to a load-bearing structure, the mounting assembly including a first support beam, a second support beam, and a clip; wherein, the first support beam is adapted to be fixed to one of the mounting surface of the photovoltaic panel facing the load-bearing structure and the load-bearing surface of the load-bearing structure facing the photovoltaic panel, and the second support beam is adapted to be fixed to the other of the mounting surface and the load-bearing surface; wherein, the mounting assembly includes a first limiting structure and a second limiting structure; wherein, the first limiting structure includes a first interlocking portion provided on the first support beam and a second interlocking portion provided on the second support beam, and the first interlocking portion is adapted to interlock with the second interlocking portion to limit the movement of the first support beam relative to the second support beam; wherein, the second limiting structure includes the clip and a receiving portion provided on at least one of the first support beam and the second support beam, and the clip is adapted to be at least partially received in the receiving portion after the first interlocking portion and the second interlocking portion are interlocked and further limit the movement of the first support beam relative to the second support beam; and wherein, the first limiting structure and the second limiting structure cooperate to fix the first support beam to the second support beam.

[0006] Compared with the method of fixing the photovoltaic panel to the load-bearing structure by gluing, fixing the first support beam to the second support beam and then fixing the photovoltaic panel to the load-bearing structure through the limiting action of the first limiting structure and the second limiting structure of the mounting assembly can facilitate the disassembly and maintenance of the photovoltaic panel. Moreover, the first support beam and the second support beam are located between the mounting surface of the photovoltaic panel and the load-bearing surface of the load-bearing structure, so that the photovoltaic panel can maintain a certain distance from the load-bearing structure, thereby improving the heat dissipation of the photovoltaic panel and preventing the photovoltaic panel from being damaged by waterlogging due to poor drainage of the load-bearing structure. In addition, fixing the first support beam or the second support beam to the mounting surface of the photovoltaic panel can also increase the stiffness of the photovoltaic panel, which is particularly beneficial for flexible photovoltaic panels and can avoid, for example, the flexible photovoltaic panel being bent and deformed or even having hidden cracks due to snow accumulation.

[0056] Figures 1A to 5E Shows a mounting assembly 10 for a photovoltaic panel according to a first embodiment of the present invention.

[0057] Refer to Figures 1A to 3B , the mounting assembly 10 according to the first embodiment of the present invention can mount the photovoltaic panel 20 to the bearing structure 30. In the illustrated embodiment, the photovoltaic panel 20 is a borderless flexible photovoltaic panel, and the bearing structure 30 is a color steel tile with a corrugated cross-section. It can be understood that in other embodiments, the photovoltaic panel can also be a non-flexible photovoltaic panel, and the bearing structure can also be any other suitable bearing structure that can provide support for the photovoltaic panel, such as the outer wall of a building, etc.

[0058] The mounting assembly 10 may include a first support beam 100, a second support beam 200, and a clip 300. The first support beam 100 may be fixed to the mounting surface 22 of the photovoltaic panel 20 facing the bearing structure 30. The second support beam 200 may be fixed to the bearing surface 32 of the bearing structure 30 facing the photovoltaic panel 20. The mounting assembly 10 includes a first limiting structure and a second limiting structure. The first limiting structure includes a first interlocking portion 102 provided on the first support beam 100 and a second interlocking portion 204 provided on the second support beam 200. The first interlocking portion 102 may be interlocked with the second interlocking portion 204 to limit the movement of the first support beam 100 relative to the second support beam 200. The second limiting structure includes the clip 300 and accommodating portions 116, 216 provided on at least one of the first support beam 100 and the second support beam 200. After the first interlocking portion 102 and the second interlocking portion 204 are interlocked, the clip 300 may be at least partially accommodated in the accommodating portions 116, 216 to further limit the movement of the first support beam 100 relative to the second support beam 200. The first limiting structure and the second limiting structure cooperate to fix the first support beam 100 to the second support beam 200. In other words, the movement of the first support beam 100 relative to the second support beam 200 in all directions is restricted.

[0059] Compared with fixing the photovoltaic panel 20 to the bearing structure 30 by gluing, fixing the first support beam 100 to the second support beam 200 through the limiting action of the first limiting structure and the second limiting structure of the mounting assembly 10 and then fixing the photovoltaic panel 20 to the bearing structure 30 can facilitate the disassembly and maintenance of the photovoltaic panel 20. Moreover, the first support beam 100 and the second support beam 200 are located between the mounting surface 22 of the photovoltaic panel 20 and the bearing surface 32 of the bearing structure 30, enabling the photovoltaic panel 20 to maintain a certain distance from the bearing structure 30, thereby improving the heat dissipation of the photovoltaic panel 20 and preventing the photovoltaic panel 20 from being damaged by waterlogging due to poor drainage of the bearing structure 30. In addition, fixing the first support beam 100 to the mounting surface 22 of the photovoltaic panel 20 can also increase the stiffness of the photovoltaic panel 20, which is particularly beneficial for flexible photovoltaic panels and can avoid, for example, the flexible photovoltaic panel being bent and deformed or even having hidden cracks due to snow accumulation.

[0060] Continuing to refer to Figures 1A to 3B , the first support beam 100 and the second support beam 200 may be made of suitable materials such as metal or polymer materials. The first support beam 100 and the second support beam 200 may be bonded to the mounting surface 22 of the photovoltaic panel 20 and the bearing surface 32 of the bearing structure 30 respectively, for example. Optionally, the first support beam and the second support beam may also be fixed to the mounting surface of the photovoltaic panel and the bearing surface of the bearing structure by other means.

[0061] The first support beam 100 includes a first substrate 106 and a first wing portion 108 extending along its longitudinal direction / length direction L1. The first substrate 106 can be fixed to the mounting surface 22 of the photovoltaic panel 20. Optionally, the first substrate 106 can be bonded to the mounting surface 22 of the photovoltaic panel 20. The first wing portion 108 extends from the first substrate 106 at an angle to the first substrate 106. In the illustrated embodiment, the first wing portion 108 is plate-shaped and extends from the first substrate 106 at an angle substantially perpendicular to the first substrate 106, in other words, the first wing portion 108 extends substantially perpendicular to the first substrate 106. It can be understood that in some other embodiments, the first wing portion 108 and the first substrate 106 can also form other suitable angles. The first support beam 100 has a substantially L-shaped cross-section, and when observed in the placement manner Figure 2B shown, the cross-section of the first support beam 100 has an inverted substantially L-shaped configuration. It can be understood that in some other embodiments, the first support beam can also have a cross-section with other suitable shapes, such as a substantially T-shaped cross-section.

[0062] The second support beam 200 includes a second substrate 206 and a second wing portion 208 extending along its longitudinal direction / length direction L2. The second substrate 206 can be fixed to the bearing surface 32 of the bearing structure 30. In the illustrated embodiment, the second substrate 206 is fixed to the surface of the trough 34 (see Figure 1B ) of the bearing structure 30 having a corrugated cross-section. The second wing portion 208 extends from the second substrate 206 at an angle to the second substrate 206. In the illustrated embodiment, the second wing portion 208 is plate-shaped and extends from the second substrate 206 at an angle substantially perpendicular to the second substrate 206, in other words, the second wing portion 208 extends substantially perpendicular to the second substrate 206. It can be understood that in some other embodiments, the second wing portion 208 and the second substrate 206 can also form other suitable angles. In the illustrated embodiment, the second support beam 200 has a substantially T-shaped cross-section, and when observed in the placement manner Figure 3B shown, the cross-section of the second support beam 200 has an inverted substantially T-shaped configuration. It can be understood that in some other embodiments, the second support beam can also have a cross-section with other suitable shapes, such as a substantially L-shaped cross-section.

[0063] The first wing portion 108 of the first support beam 100 is provided with a first interlocking portion 102, and the second wing portion 208 of the second support beam 200 is provided with a second interlocking portion 204. The longitudinal direction L1 of the first support beam 100 and the longitudinal direction L2 of the second support beam 200 are substantially parallel to each other when the first interlocking portion 102 and the second interlocking portion 204 are interlocked. In the illustrated embodiment, when the first interlocking portion 102 and the second interlocking portion 204 are interlocked with each other, the first wing portion 108 and the second wing portion 208 are in contact with each other, and the first substrate 106 and the second substrate 206 are substantially parallel to each other and spaced apart by a certain distance. The interlocking of the first interlocking portion 102 and the second interlocking portion 204 can limit the movement of the first support beam 100 away from the second support beam 200 in a direction substantially perpendicular to the first substrate 106 / second substrate 206.

[0064] In the illustrated embodiment, the first wing portion 108 has a first wing portion body 110, and the first interlocking portion 102 is in the form of a convex portion and protrudes relative to the first wing portion body 110. The second wing portion 208 has a second wing portion body 210, and the second interlocking portion 204 is in the form of a concave portion and is recessed relative to the second wing portion body 210. In the illustrated embodiment, the first interlocking portion 102 includes two longitudinal ribs 103, and correspondingly, the second interlocking portion 204 includes two longitudinal grooves 205. It can be understood that in other embodiments, the first interlocking portion may include other suitable numbers of longitudinal ribs, and correspondingly, the second interlocking portion may include other suitable numbers of longitudinal grooves; in still other embodiments, the first interlocking portion may be in the form of a concave portion and the second interlocking portion may be in the form of a convex portion.

[0065] When assembling the mounting assembly 10 (i.e., fixing the first support beam 100 to the second support beam 200), as Figures 5A to 5D shown, the first support beam 100 can be first moved closer to the second support beam 200, and the position of the first support beam 100 can be adjusted so that the first interlocking portion 102 of the first limiting structure and the second interlocking portion 204 are interlocked with each other, so that the mounting assembly 10 is in the Figure 5D pre-installed state. Then, as Figure 5E shown, by using the clip 300 of the second limiting structure, the movement of the first support beam 100 relative to the second support beam 200 is further restricted (more specifically, the movement of the first wing portion 108 relative to the second wing portion 208 is restricted), so that the first support beam 100 is fixed to the second support beam 200. At this time, the mounting assembly 10 changes from the Figure 5D pre-installed state to the Figure 5E final installed state, which will be further described below.

[0066] Referring to Figures 2A to 3B and Figures 5A to 5D, the second support beam 200 includes a guiding convex portion 212. The guiding convex portion 212 is disposed on the second substrate 206, and the guiding convex portion 212 is spaced apart from the second wing portion 208 to form a channel 214 between the guiding convex portion 212 and the second wing portion 208. The guiding convex portion 212 can guide the first wing portion 108 to move toward the second wing portion 208 when the first wing portion 108 moves toward the second substrate 206 and enters the channel 214 along the guiding convex portion 212 during the assembly of the first support beam 100 and the second support beam 200, so that the first interlocking portion 102 is interlocked with the second interlocking portion 204.

[0067] Specifically, referring to Figures 5A to 5D , during the assembly of the first support beam 100 and the second support beam 200, the first support beam 100 can be moved in a direction substantially perpendicular to the first substrate 106 to approach the second support beam 200 (as Figure 5A shown), so that the first wing portion 108 enters the channel 214 between the guiding convex portion 212 and the second wing portion 208 along the guiding convex portion 212 (as Figure 5B shown), and then the first wing portion 108 will approach the second wing portion 208 under the guiding action of the guiding convex portion 212. As Figure 5C shown, when the first wing portion 108 continues to move along the guiding convex portion 212 until the distal end of the first wing portion 108 away from the first substrate 106 abuts against the second substrate 206, the first interlocking portion 102 and the second interlocking portion 204 are substantially aligned. Then, as Figure 5D shown, gently pull the first support beam 100 along the second substrate 206 so that the first wing portion 108 and the second wing portion 208 are in contact, and the first interlocking portion 102 can be interlocked with the second interlocking portion 204, in other words, the pre-installation of the first support beam 100 and the second support beam 200 is achieved.

[0068] Referring to Figures 2A to 3B and Figures 5A to 5D , in the illustrated embodiment, the guiding convex portion 212 has a guiding surface 213 inclined with respect to the second substrate 206. The first wing portion 108 is provided with a sliding surface 109 at its distal end away from the first substrate 106. The sliding surface 109 can slide along the guiding surface 213 when the first wing portion 108 moves toward the second substrate 206 and enters the channel 214 along the guiding convex portion 212, thereby guiding the first wing portion 108 to move toward the second wing portion 208. In the illustrated embodiment, the first interlocking portion 102 and the sliding surface 109 are respectively disposed on opposite sides of the first wing portion body 110.

[0069] In the illustrated embodiment, the first interlocking portion 102 is configured not to mechanically interfere with the second wing portion 208 during the movement of the first wing portion 108 towards the second substrate 206 and along the guiding protrusion 212 into the channel 214; and the second interlocking portion 204 is configured not to mechanically interfere with the first wing portion 108 during the movement of the first wing portion 108 towards the second substrate 206 and along the guiding protrusion 212 into the channel 214. This can be achieved, for example, by reasonably designing the shapes and dimensions of the first interlocking portion 102 and the second interlocking portion 204. Thus, the first wing portion 108 can be allowed to smoothly move along the guiding protrusion 212 and approach the second wing portion 208 without hindrance.

[0070] Continuing to refer to Figures 1A to 3B , the second limiting structure includes a clip 300, a first accommodating portion 116 in an open form penetrating through the first wing portion 108, and a second accommodating portion 216 in an open form penetrating through the second wing portion 208. The clip 300 is configured to extend through the first accommodating portion 116 and the second accommodating portion 216 after the first interlocking portion 102 and the second interlocking portion 204 are interlocked and the first accommodating portion 116 and the second accommodating portion 216 are substantially aligned, so as to fix the first wing portion 108 to the second wing portion 208, and further fix the first support beam 100 to the second support beam 200. In other words, to transform the mounting assembly 10 into the final mounted state.

[0071] An exemplary structure of the clip 300 is shown in Figure 4A and Figure 4B . A structure similar to this exemplary structure of the clip 300 is described in detail in the patent application CN103348145A, and only a simple description will be given here without further elaboration.

[0072] The clip 300 has a cover plate 304 with a generally rectangular shape in the top region 302. Two elastic arms 306 are formed at opposite ends of the cover plate 304, and each elastic arm 306 is transverse to the longitudinal direction L of the cover plate 304 and extends from the cover plate 304 towards the bottom region 308 opposite to the top region 302. Two side walls 310 are formed at opposite longitudinal edges of the cover plate 304, and these side walls 310 are substantially at right angles to the cover plate 304 and thus together with the cover plate 304 form a U-shaped shape. Two rod arms 312 extend respectively from the middle portions of the two side walls 310. Each rod arm has an outer wall 314 and an inner wall 316, and the inner wall is connected to the outer wall 314 through a bending section 318. A pair of support crank arms 320 are provided on each inner wall 316, and each support crank arm 320 includes a support section 322. Optionally, the clip 300 is made of a metal material.

[0073] Referring to Figures 2A to 4B and Figure 5E, after the clip 300 extends through the first accommodating portion 116 and the second accommodating portion 216 and is installed in place, on the one hand, the clip 300 can cooperate with the first accommodating portion 116 and the second accommodating portion 216 to limit the movement of the first wing portion 108 relative to the second wing portion 208 in a direction perpendicular to the extending direction E of the clip 300 within the first accommodating portion 116 and the second accommodating portion 216. On the other hand, the elastic arm 306 of the clip 300 and the supporting section 322 of the supporting crank arm 320 will clamp the first wing portion 108 and the second wing portion 208 therebetween, thereby restricting the movement of the first wing portion 108 relative to the second wing portion 208 in the extending direction E of the clip 300. In this way, the first support beam 100 is fixed to the second support beam 200 through the second limiting structure.

[0074] It should be understood that the structure of the clip is not limited to the illustrated exemplary configuration, but can have various configurations as long as it can pass through the first accommodating portion and the second accommodating portion and conveniently fix the first wing portion to the second wing portion by means of clamping. For example, the clip can also be the clip disclosed in CN105041796A, CN106363551A, CN107288966A, CN107850098A.

[0075] Returning to Figures 1A to 3B , in the illustrated embodiment, the mounting assembly 10 includes three first support beams 100 and three second support beams 200. The three first support beams 100 can be fixedly arranged on the mounting surface 22 in parallel and spaced apart from each other, and each first support beam 100 includes a first interlocking portion 102 and two first accommodating portions 116. The three second support beams 200 can be fixedly arranged on the bearing surface 32 in parallel and spaced apart from each other, and each second support beam 200 includes a second interlocking portion 204 and two second accommodating portions 216. The first interlocking portion 102 of each first support beam 100 can be interlocked with the second interlocking portion 204 of a corresponding second support beam 200 to bring the mounting assembly 10 into a pre-mounted state. After the mounting assembly 10 is in the pre-mounted state, each first support beam 100 can be further fixed to the corresponding second support beam 200 through two clips 300 to convert the mounting assembly 10 to the final mounted state. It can be understood that in other embodiments, the mounting assembly can include other suitable numbers of first support beams, second support beams and clips, each first support beam can have other suitable numbers of first interlocking portions and first accommodating portions, and each second support beam can have other suitable numbers of second interlocking portions and second accommodating portions.

[0076] The following exemplarily describes the operation mode of using the mounting assembly 10 to install / fix the photovoltaic panel 20 to a bearing structure 30 in the form of, for example, a roof color steel tile.

[0077] Referring toFigures 1A to 5E , first, fix the first substrate 106 of the first support beam 100 to the mounting surface 22 of the photovoltaic panel 20 and fix the second substrate 206 of the second support beam 200 to the bearing surface 32 of the bearing structure 30. Then, lift the photovoltaic panel 20 directly above the bearing structure 30 so that the first wing portion 108 of the first support beam 100 faces the guiding convex portion 212. Then, gently lower the photovoltaic panel 20 relative to the bearing structure 30 so that the distal end of the first wing portion 108 moves along the guiding convex portion 212 until the distal end of the first wing portion 108 abuts against the second substrate 206 and stops moving. At this time, then pull the photovoltaic panel 20 substantially horizontally so that the first wing portion 108 and the second wing portion 208 are fitted together, and the first interlocking portion 102 and the second interlocking portion 204 can be interlocked with each other, that is, the pre-installation of the first support beam 100 and the second support beam 200 is realized. Then, by, for example, sliding the first wing portion 108 relative to the second wing portion 208 along the longitudinal direction L2 of the second support beam 200, the positions of the first support beam 100 and the second support beam 200 are adjusted so that the first accommodating portion 116 and the second accommodating portion 216 are substantially aligned. Finally, insert the clip 300 through the first accommodating portion 116 and the second accommodating portion 216 and install it in place, and the final installation of the first support beam 100 and the second support beam 200 can be realized. In other words, the installation and fixation of the photovoltaic panel 20 on the bearing structure 30 are realized.

[0078] It can be understood that the first substrate of the first support beam can also be fixed to the bearing surface of the bearing structure, and the second substrate of the second support beam can be fixed to the mounting surface of the photovoltaic panel, and then the first support beam and the second support beam are installed together by a clip, so as to realize the installation and fixation of the photovoltaic panel on the bearing structure.

[0079] Figures 6A to 8C The installation assembly 10 for a photovoltaic panel according to the second embodiment of the present invention is shown. The installation assembly for a photovoltaic panel according to the second embodiment is similar to the installation assembly for a photovoltaic panel according to the first embodiment. The main difference is that the first support beam 100 and the second support beam 200 of the installation assembly 10 for a photovoltaic panel according to the second embodiment have the same structure. The differences between the two embodiments will be mainly described below.

[0080] Refer to Figures 6A to 8C , the installation assembly 10 according to the second embodiment of the present invention can install and fix the photovoltaic panel 20 to the bearing structure 30. The installation assembly 10 may include a first support beam 100, a second support beam 200 and a clip 300. The first support beam 100 and the second support beam 200 have the same structure. As Figure 6BAs shown, in use, one of the first support beam 100 and the second support beam 200 is placed upside down relative to the other. The first support beam 100 is fixed to the mounting surface 22 of the photovoltaic panel 20 facing the bearing structure 30. The second support beam 200 is fixed to the bearing surface 32 of the bearing structure 30 facing the photovoltaic panel 20. The mounting assembly 10 includes a first limiting structure and a second limiting structure. The first limiting structure includes a first interlocking portion 102 and a second interlocking portion 104 provided on the first support beam 100 and a first interlocking portion 202 and a second interlocking portion 204 provided on the second support beam 200. The first interlocking portion 102 of the first support beam 100 can be interlocked with the second interlocking portion 204 of the second support beam 200 and the second interlocking portion 104 of the first support beam 100 can be interlocked with the first interlocking portion 202 of the second support beam 200 to limit the movement of the first support beam 100 relative to the second support beam 200. The second limiting structure includes a clip 300 and a first receiving portion 116 provided on the first support beam 100 and a second receiving portion 216 provided on the second support beam 200. The clip 300 can be at least partially received in the first receiving portion 116 and the second receiving portion 216 after the first interlocking portion 102 and the second interlocking portion 204 are interlocked and further limit the movement of the first support beam 100 relative to the second support beam 200. The first limiting structure and the second limiting structure cooperate to fix the first support beam 100 to the second support beam 200.

[0081] Continuing to refer to Figures 6A to 8C , the first support beam 100 includes a first substrate 106 and a first wing portion 108 extending along its longitudinal direction. The first substrate 106 can be fixed to the mounting surface 22 of the photovoltaic panel 20. The first wing portion 108 extends from the first substrate 106 at an angle substantially perpendicular to the first substrate 106. The second support beam 200 includes a second substrate 206 and a second wing portion 208 extending along its longitudinal direction. The second substrate 206 can be fixed to the bearing surface 32 of the bearing structure 30. The second wing portion 208 extends from the second substrate 206 at an angle substantially perpendicular to the second substrate 206. The first substrate 106 of the first support beam 100 has the same structure as the second substrate 206 of the second support beam 200, and the first wing portion 108 of the first support beam 100 has the same structure as the second wing portion 208 of the second support beam 200.

[0082] The first wing portion 108 of the first support beam 100 is provided with a first interlocking portion 102 and a second interlocking portion 104, and the second wing portion 208 of the second support beam 200 is provided with a first interlocking portion 202 and a second interlocking portion 204. The first interlocking portion 102 of the first wing portion 108 can be interlocked with the second interlocking portion 204 of the second wing portion 208, and the second interlocking portion 104 of the first wing portion 108 can be interlocked with the first interlocking portion 202 of the second wing portion 208. In the illustrated embodiment, when the first interlocking portions 102, 202 and the second interlocking portions 104, 204 are interlocked with each other, the longitudinal direction of the first support beam 100 and the longitudinal direction of the second support beam 200 are substantially parallel to each other, the first wing portion 108 and the second wing portion 208 are in contact with each other, and the first substrate 106 and the second substrate 206 are substantially parallel to each other and spaced apart by a certain distance. The interlocking of the first interlocking portions 102, 202 and the second interlocking portions 104, 204 can restrict the first support beam 100 from moving away from the second support beam 200 in a direction substantially perpendicular to the first substrate 106 / second substrate 206.

[0083] In the illustrated embodiment, the first wing portion 108 has a first wing portion body 110. The first interlocking portion 102 of the first wing portion 108 is in the form of a concave portion and is recessed relative to the first wing portion body 110. The second interlocking portion 104 of the first wing portion 108 is in the form of a convex portion and protrudes relative to the first wing portion body 110. The first interlocking portion 102 and the second interlocking portion 104 of the first wing portion 108 are respectively provided at the distal end of the first wing portion 108 away from the first substrate 106 and the proximal end of the first wing portion 108 close to the first substrate 106. The second wing portion 208 has a second wing portion body 210. The first interlocking portion 202 of the second wing portion 208 is in the form of a concave portion and is recessed relative to the second wing portion body 210. The second interlocking portion 204 of the second wing portion 208 is in the form of a convex portion and protrudes relative to the second wing portion body 210. The first interlocking portion 202 and the second interlocking portion 204 of the second wing portion 208 are respectively provided at the distal end of the second wing portion 208 away from the second substrate 206 and the proximal end of the second wing portion 208 close to the second substrate 206.

[0084] It can be understood that in other embodiments, the first interlocking portion of the first wing portion and the first interlocking portion of the second wing portion can be in the form of convex portions, while the second interlocking portion of the first wing portion and the second interlocking portion of the second wing portion can be in the form of concave portions.

[0085] In the illustrated embodiment, the first support beam 100 includes a first guiding protrusion 112 disposed on the first substrate 106. The first guiding protrusion 112 is spaced apart from the first wing portion 108 to form a first channel 114 between the first guiding protrusion 112 and the first wing portion 108. The second support beam 200 includes a second guiding protrusion 212 disposed on the second substrate 206. The second guiding protrusion 212 is spaced apart from the second wing portion 208 to form a second channel 214 between the second guiding protrusion 212 and the second wing portion 208.

[0086] The first guiding protrusion 112 can guide the second wing portion 208 to move toward the first wing portion 108 when the second wing portion 208 moves toward the first substrate 106 and enters the first channel 114 along the first guiding protrusion 112 during the assembly of the first support beam 100 and the second support beam 200. The second guiding protrusion 212 can guide the first wing portion 108 to move toward the second wing portion 208 when the first wing portion 108 moves toward the second substrate 206 and enters the second channel 214 along the second guiding protrusion 212 during the assembly of the first support beam 100 and the second support beam 200, so that the first interlocking portion 102 of the first wing portion 108 interlocks with the second interlocking portion 204 of the second wing portion 208 and the second interlocking portion 104 of the first wing portion 108 interlocks with the first interlocking portion 202 of the second wing portion 208.

[0087] Continuing to refer to Figures 6A to 8C , the first wing portion body 110 has a hollow structure and has a first outer wall 118 and a first inner wall 120. A first window 122 is disposed on the first outer wall 118, and a first receiving portion 116 in the form of an opening is disposed on the first inner wall 120. The first window 122 and the first receiving portion 116 are substantially aligned with each other, and the size of the first window 122 is larger than the size of the first receiving portion 116, so that the clip 300 is received in the first receiving portion 116 through the first window 122. Similarly, the second wing portion body 210 has a hollow structure and has a second outer wall 218 and a second inner wall 220. A second window 222 is disposed on the second outer wall 218, and a second receiving portion 216 in the form of an opening is disposed on the second inner wall 220. The second window 222 and the second receiving portion 216 are substantially aligned with each other, and the size of the second window 222 is larger than the size of the second receiving portion 216, so that the clip 300 is received in the second receiving portion 216 through the second window 222. The clip 300 is configured to extend through the first receiving portion 116 and the second receiving portion 216 after the first interlocking portion 102 and the second interlocking portion 204 are interlocked and the first receiving portion 116 and the second receiving portion 216 are substantially aligned, so as to fix the first wing portion 108 to the second wing portion 208, such that the first support beam 100 is fixed to the second support beam 200, and further such that the photovoltaic panel 20 is installed and fixed to the carrier structure 30.

[0088] Figures 6A to 7 The clip 300 in Figure 4A and Figure 4B has the same structure as the clip in, which will not be elaborated here.

[0089] Figures 9A to 13D Fig. shows an installation assembly 10 for a photovoltaic panel according to a third embodiment of the present invention.

[0090] Referring to Figures 9A to 11B , the installation assembly 10 according to the third embodiment of the present invention can mount the photovoltaic panel 20 to the bearing structure 30. The installation assembly 10 may include a first support beam 100, a second support beam 200, and a clip 300. The first support beam 100 may be fixed to the mounting surface 22 of the photovoltaic panel 20 facing the bearing structure 30. The second support beam 200 may be fixed to the bearing surface 32 of the bearing structure 30 facing the photovoltaic panel 20. The installation assembly 10 includes a first limiting structure and a second limiting structure. The first limiting structure includes a first interlocking portion 102 provided on the first support beam 100 and a second interlocking portion 204 provided on the second support beam 200. The first interlocking portion 102 can be interlocked with the second interlocking portion 204 to limit the movement of the first support beam 100 relative to the second support beam 200. The second limiting structure includes the clip 300 and a receiving portion 216 provided on the second support beam 200. After the first interlocking portion 102 and the second interlocking portion 204 are interlocked, the clip 300 can be at least partially received in the receiving portion 216 and further limit the movement of the first support beam 100 relative to the second support beam 200. The first limiting structure and the second limiting structure cooperate to fix the first support beam 100 to the second support beam 200.

[0091] Referring to Figures 9A to 11B , the first support beam 100 and the second support beam 200 can be made of suitable materials such as metal or polymer materials. In the illustrated embodiment, the first support beam 100 has a generally T-shaped cross-section and includes a first substrate 106 extending along its longitudinal direction L1 and a first wing portion 108. The first substrate 106 can be fixed to the mounting surface 22 of the photovoltaic panel 20. The first wing portion 108 is plate-shaped and extends from the first substrate 106 at a substantially right angle to the first substrate 106. The second support beam 200 has a generally T-shaped cross-section and includes a second substrate 206 extending along its longitudinal direction L2 and a second wing portion 208. The second substrate 206 can be fixed to the bearing surface 32 of the bearing structure 30. The second wing portion 208 is plate-shaped and extends from the second substrate 206 at a substantially right angle to the second substrate 206.

[0092] The first wing portion 108 of the first support beam 100 is provided with a plurality of first interlocking portions 102, and the second wing portion 208 of the second support beam 200 is provided with a plurality of second interlocking portions 204. The longitudinal direction L1 of the first support beam 100 and the longitudinal direction L2 of the second support beam 200 are substantially perpendicular to each other when the first interlocking portion 102 and the second interlocking portion 204 are interlocked. In the illustrated embodiment, the first interlocking portion 102 is in the form of a through hole penetrating the first wing portion 108, and the second interlocking portion 204 is in the form of a finger portion and extends substantially along the longitudinal direction L2 of the second support beam 200. Each second interlocking portion 204 can be inserted into a corresponding first interlocking portion 102 to interlock with the first interlocking portion 102. The interlocking of the first interlocking portion 102 and the second interlocking portion 204 can limit the movement of the first support beam 100 relative to the second support beam 200 in a direction perpendicular to the longitudinal direction L2 of the second support beam 200. The shape and size of the first interlocking portion 102 can match the shape and size of the cross section of the second interlocking portion 204 to achieve a better limiting effect.

[0093] In the illustrated embodiment, the second wing portion 208 includes a plurality of guide grooves 224, and each guide groove 224 is adjacent to a corresponding second interlocking portion 204. The guide grooves 224 penetrate the second wing portion 208 and have open inlet ends 226. The first wing portion 108 can enter the guide grooves 224 through the inlet ends 226 and move relative to the second wing portion 208 along the guide grooves 224 until the second interlocking portion 204 is inserted in place in the first interlocking portion 102 (i.e., until the first interlocking portion 102 and the second interlocking portion 204 are interlocked). During the manufacturing process of the second support beam 200, the second interlocking portion 204 can be formed by opening the guide grooves 224 in the second wing portion 208.

[0094] In the illustrated embodiment, the guide grooves 224 have a substantially L-shaped configuration and include a first segment 228 and a second segment 230 that communicate with each other. The first segment 228 extends substantially perpendicular to the longitudinal direction L2 of the second support beam 200 and includes the inlet end 226, and the second segment 230 extends substantially along the longitudinal direction L2 of the second support beam 200.

[0095] With reference to Figures 13A to 13C and during the assembly of the mounting assembly 10, the first wing portion 108 of the first support beam 100 can be first moved in a direction substantially perpendicular to the second substrate 206 of the second support beam 200 into the first segment 228 of the guide grooves 224 of the second wing portion 208 until the distal end of the first wing portion 108 remote from the first substrate 106 abuts against the side wall of the second segment 230 of the guide grooves 224, as shown in Figure 13BAs shown. Next, adjust the relative positions of the first wing portion 108 and the second wing portion 208 such that the first interlocking portion 102 and the second interlocking portion 204 are substantially aligned in the longitudinal direction L2 of the second support beam 200. Then, move the first wing portion 108 relative to the second wing portion 208 along the second segment 230 such that the second interlocking portion 204 is inserted into the first interlocking portion 102 until the second interlocking portion 204 is fully inserted into the first interlocking portion 102 (i.e., until the first interlocking portion 102 and the second interlocking portion 204 are interlocked), thereby placing the mounting assembly 10 in a pre-mounted state, as Figure 13C shown.

[0096] After that, as Figure 13D shown, further restrict the movement of the first support beam 100 relative to the second support beam 200 (more specifically, restrict the movement of the first wing portion 108 relative to the second wing portion 208) by using the second limiting structure, thereby fixing the first support beam 100 to the second support beam 200. At this time, the mounting assembly 10 changes from the pre-mounted state to the final mounted state, which will be further described below.

[0097] Referring to Figures 9A to 12B , the second limiting structure includes a clip 300 and a receiving portion 216 provided at the second segment 230 of the guiding groove 224 of the second wing portion 208. The clip 300 is configured to be at least partially received in the receiving portion 216 after the first interlocking portion 102 and the second interlocking portion 204 are interlocked to prevent the first wing portion 108 from moving along the guiding groove 224 and causing the first interlocking portion 102 and the second interlocking portion 204 to be disengaged.

[0098] In the illustrated embodiment, the clip 300 is generally U-shaped and includes two relatively arranged clamping arms 324 and a connecting portion 326 connecting the two clamping arms 324. Optionally, the clip 300 is made of a metallic material. The receiving portion 216 includes two notches 232 respectively provided on opposite sides of the guiding groove 224. The clip 300 can be received in the receiving portion 216 such that: the two clamping arms 324 are substantially perpendicular to the second wing portion 208 and respectively engage with the two notches 232 to restrict the movement of the clip 300 relative to the second wing portion 208 in the longitudinal direction L2 of the second support beam 200.

[0099] At least one of the two clamping arms 324 can be provided with a slotted opening 330 at its side edge. The slotted opening 330 can engage with the second wing portion 208 to restrict the movement of the clip 300 relative to the second wing portion 208 in a direction perpendicular to the second wing portion 208. In the illustrated embodiment, each of the two clamping arms 324 is provided with a slotted opening 330 at its side edge.

[0100] Thus, through the engagement of the clamping arm 324 with the notch 232 on the second wing portion 208 and the engagement of the slot 330 on the clamping arm 324 with the second wing portion 208, the clip 300 can be stably held in the receiving portion 216. When the first interlocking portion 102 and the second interlocking portion 204 are interlocked with each other and the clip 300 is held in the receiving portion 216, the clip 300 is located on the moving path of the first wing portion 108 moving away from the second wing portion 208 along the guiding groove 224, thereby preventing the first interlocking portion 102 and the second interlocking portion 204 from disengaging from each other and releasing the interlock.

[0101] In Figure 9A and Figure 9B In the illustrated embodiment, the mounting assembly 10 includes three first support beams 100 and three second support beams 200. The three first support beams 100 can be fixedly secured to the mounting surface 22 of the photovoltaic panel 20 in parallel and spaced apart from each other, wherein each first support beam 100 includes three first interlocking portions 102. The three second support beams 200 can be fixedly secured to the bearing surface 32 of the bearing structure 30 in parallel and spaced apart from each other, wherein each second support beam 200 includes three second interlocking portions 204 and three receiving portions 216. The three second interlocking portions 204 of each second support beam 200 can be respectively interlocked with a corresponding first interlocking portion 102 of the three first support beams 100 to bring the mounting assembly 10 into a pre-mounted state. After the mounting assembly 10 is in the pre-mounted state, four clips 300 can be used at four positions where the outermost two first support beams 100 and the outermost two second support beams 200 are interlocked with each other through the first limiting structure, so as to convert the mounting assembly 10 to the final mounted state (i.e., the state where the first support beam is fixed to the second support beam). It can be understood that in other embodiments, the mounting assembly may include other suitable numbers of first support beams, second support beams and clips, each first support beam may have other suitable numbers of first interlocking portions, and each second support beam may have other suitable numbers of second interlocking portions and receiving portions.

[0102] The following exemplarily describes the operation mode of using the mounting assembly 10 to fix the photovoltaic panel 20 to a bearing structure 30 in the form of, for example, a roof color steel tile.

[0103] Referring to Figures 9A to 13D , first, the first substrate 106 of the first support beam 100 is fixed to the mounting surface 22 of the photovoltaic panel 20 and the second substrate 206 of the second support beam 200 is fixed to the bearing surface 32 of the bearing structure 30. Then, the photovoltaic panel 20 is lifted directly above the bearing structure 30 such that the longitudinal direction L1 of the first support beam 100 is substantially perpendicular to the longitudinal direction L2 of the second support beam 200, and the first wing portion 108 is substantially aligned with the first section 228 of the guiding groove 224, as Figure 13AAs shown. Then, gently lower the photovoltaic panel 20 relative to the carrying structure 30 such that the first wing portion 108 moves along the first section 228 of the guiding groove 224 until the distal end of the first wing portion 108 abuts against the side wall of the second section 230 of the guiding groove 224 and stops moving, as Figure 13B shown. Next, adjust the relative positions of the first wing portion 108 and the second wing portion 208 such that the first interlocking portion 102 and the second interlocking portion 204 are substantially aligned. Then, pull the photovoltaic panel 20 substantially horizontally such that the first wing portion 108 moves along the second section 230 of the guiding groove 224 until the second interlocking portion 204 is inserted into place in the first interlocking portion 102, thereby achieving pre-installation of the first support beam 100 and the second support beam 200, as Figure 13C shown. Finally, insert the clip 300 through the receiving portion 216 on the second wing portion 208 into place, thereby achieving final installation / fixing of the first support beam 100 and the second support beam 200, in other words, achieving installation and fixing of the photovoltaic panel 20 on the carrying structure 30, as Figure 13D shown.

[0104] Figures 14A to 15B Fig. shows an installation assembly 10 for a photovoltaic panel according to a fourth embodiment of the present invention. The installation assembly for a photovoltaic panel according to the fourth embodiment is similar to the installation assembly for a photovoltaic panel according to the second embodiment.

[0105] Referring to Figures 14A to 15B , the installation assembly 10 according to the fourth embodiment of the present invention may include a first support beam 100, a second support beam 200, and a clip 300. The first support beam 100 and the second support beam 200 have the same structure. As Figure 14A and 14BAs shown, during use, one of the first support beam 100 and the second support beam 200 is placed upside down relative to the other. The first support beam 100 can be fixed to the mounting surface of the photovoltaic panel facing the bearing structure. The second support beam 200 can be fixed to the bearing surface of the bearing structure facing the photovoltaic panel. The mounting assembly 10 includes a first limiting structure and a second limiting structure. The first limiting structure includes a first interlocking portion 102 and a second interlocking portion 104 provided on the first support beam 100 and a first interlocking portion 202 and a second interlocking portion 204 provided on the second support beam 200. The first interlocking portion 102 of the first support beam 100 can be interlocked with the second interlocking portion 204 of the second support beam 200 and the second interlocking portion 104 of the first support beam 100 can be interlocked with the first interlocking portion 202 of the second support beam 200 to limit the movement of the first support beam 100 relative to the second support beam 200. The second limiting structure includes a clip 300 and a first receiving portion 116 provided on the first support beam 100 and a second receiving portion 216 provided on the second support beam 200. The clip 300 can be at least partially received in the first receiving portion 116 and the second receiving portion 216 after the first interlocking portions 102, 202 and the second interlocking portions 104, 204 are interlocked and further limit the movement of the first support beam 100 relative to the second support beam 200. The first limiting structure and the second limiting structure cooperate to fix the first support beam 100 to the second support beam 200.

[0106] Continuing to refer to Figures 14A to 15B , the first support beam 100 includes a first substrate 106 and a first wing portion 108 extending along its longitudinal direction. The first substrate 106 can be fixed to the mounting surface of the photovoltaic panel. The first wing portion 108 extends from the first substrate 106 at an angle substantially perpendicular to the first substrate 106. The second support beam 200 includes a second substrate 206 and a second wing portion 208 extending along its longitudinal direction. The second substrate 206 can be fixed to the bearing surface of the bearing structure. The second wing portion 208 extends from the second substrate 206 at an angle substantially perpendicular to the second substrate 206. The first substrate 106 of the first support beam 100 has the same structure as the second substrate 206 of the second support beam 200, and the first wing portion 108 of the first support beam 100 has the same structure as the second wing portion 208 of the second support beam 200.

[0107] The first wing portion 108 of the first support beam 100 is provided with a first interlocking portion 102 and a second interlocking portion 104, and the second wing portion 208 of the second support beam 200 is provided with a first interlocking portion 202 and a second interlocking portion 204. The first interlocking portion 102 of the first wing portion 108 can be interlocked with the second interlocking portion 204 of the second wing portion 208, and the second interlocking portion 104 of the first wing portion 108 can be interlocked with the first interlocking portion 202 of the second wing portion 208. In the illustrated embodiment, when the first interlocking portions 102, 202 and the second interlocking portions 104, 204 are interlocked with each other, the longitudinal direction of the first support beam 100 and the longitudinal direction of the second support beam 200 are substantially parallel to each other, the first wing portion 108 and the second wing portion 208 are in contact with each other, and the first substrate 106 and the second substrate 206 are substantially parallel to each other and spaced apart by a certain distance.

[0108] The interlocking of the first interlocking portions 102, 202 and the second interlocking portions 104, 204 can limit the movement of the first support beam 100 away from the second support beam 200 in a direction substantially perpendicular to the first substrate 106 / second substrate 206. In the illustrated embodiment, the first interlocking portion 102 of the first support beam 100 can have a first abutting surface 111, the second interlocking portion 204 of the second support beam 200 can have a second abutting surface 211, the first abutting surface 111 and the second abutting surface 211 extend substantially parallel to the first substrate 106 / second substrate 206, and are adapted to abut against each other to limit the movement of the first support beam 100 away from the second support beam 200 in a direction substantially perpendicular to the first substrate 106 / second substrate 206. Thus, when a lifting force F1 (the lifting force F1 can be applied to the first support beam 100 by the photovoltaic panel when the photovoltaic panel fixed to the first support beam 100 is subjected to an upward wind force, see Figure 14A ) acts on the middle portion of the first support beam 100 of the mounting assembly 10, especially between the two clips 300, the first abutting surface 111 and the second abutting surface 211 can abut against each other to preferably prevent the first support beam 100 and the second support beam 200 from moving away from each other in a direction substantially perpendicular to the first substrate 106 / second substrate 206 at the middle portion of the mounting assembly 10 between the two clips 300. The second interlocking portion 104 of the first support beam 100 and the first interlocking portion 202 of the second support beam 200 are also provided with such abutting surfaces, which will not be elaborated here.

[0109] In the illustrated embodiment, the first support beam 100 includes a first limiting protrusion 115 disposed on the first substrate 106, and the first limiting protrusion 115 is spaced apart from the first wing portion 108. The first limiting protrusion 115 of the first support beam 100 is adapted to abut against the second wing portion 208 of the second support beam 200 to limit the first wing portion 108 and the second wing portion 208 from moving away from each other. The second support beam 200 includes a second limiting protrusion 215 disposed on the second substrate 206, and the second limiting protrusion 215 is spaced apart from the second wing portion 208. The second limiting protrusion 215 of the second support beam 200 is adapted to abut against the first wing portion 108 of the first support beam 100 to limit the first wing portion 108 and the second wing portion 208 from moving away from each other. Thus, when a pressing force F2 (see Figure 15A ) is applied to the middle portion of the first support beam 100 of the mounting assembly 10 located between the two clips 300, causing the first support beam 100 to partially slip downward relative to the second support beam 200, the first limiting protrusion 115 can abut against the second wing portion 208 and the second limiting protrusion 215 can abut against the first wing portion 108 (see Figure 15B ), to limit the first wing portion 108 and the second wing portion 208 from moving away from each other, thereby avoiding a large longitudinal gap from being generated between the first support beam 100 and the second support beam 200. The aforementioned pressing force F2 can be applied to the first support beam 100 by the photovoltaic panel, for example, when the photovoltaic panel fixed to the first support beam 100 is subjected to a downward wind force or snow pressure.

[0110] Figures 14A to 15A The clip 300 in Figure 4A and Figure 4B has the same structure as the clip in

[0111] Figure 16 and will not be described in detail here.

[0112] The first wing portion 108 of the first support beam 100 of the mounting assembly 10 according to the fifth embodiment is provided with a first interlocking portion 102 and a second interlocking portion 104, and the second wing portion 208 of the second support beam 200 is provided with a first interlocking portion 202 and a second interlocking portion 204. The first interlocking portion 102 of the first wing portion 108 can be interlocked with the second interlocking portion 204 of the second wing portion 208, and the second interlocking portion 104 of the first wing portion 108 can be interlocked with the first interlocking portion 202 of the second wing portion 208.

[0113] In the illustrated embodiment, the first support beam 100 includes a first guiding protrusion 112 disposed on the first substrate 106. The first guiding protrusion 112 is spaced apart from the first wing portion 108 to form a first channel 114 between the first guiding protrusion 112 and the first wing portion 108. The second support beam 200 includes a second guiding protrusion 212 disposed on the second substrate 206. The second guiding protrusion 212 is spaced apart from the second wing portion 208 to form a second channel 214 between the second guiding protrusion 212 and the second wing portion 208. The first guiding protrusion 112 can guide the second wing portion 208 to move toward the first wing portion 108 when the second wing portion 208 moves toward the first substrate 106 and enters the first channel 114 along the first guiding protrusion 112 during the assembly of the first support beam 100 and the second support beam 200. The second guiding protrusion 212 can guide the first wing portion 108 to move toward the second wing portion 208 when the first wing portion 108 moves toward the second substrate 206 and enters the second channel 214 along the second guiding protrusion 212 during the assembly of the first support beam 100 and the second support beam 200, so that the first interlocking portion 102 of the first wing portion 108 is interlocked with the second interlocking portion 204 of the second wing portion 208 and the second interlocking portion 104 of the first wing portion 108 is interlocked with the first interlocking portion 202 of the second wing portion 208.

[0114] In the illustrated embodiment, a first groove 134 is provided on the first guiding protrusion 112 of the first support beam 100. Correspondingly, a first protrusion 236 is provided on the second wing portion 208 of the second support beam 200. When the second interlocking portion 104 of the first wing portion 108 is interlocked with the first interlocking portion 202 of the second wing portion 208, the first groove 134 engages with the first protrusion 236. The second interlocking portion 104 of the first wing portion 108 has an arcuate surface segment 138, and the first interlocking portion 202 of the second wing portion 208 has an arcuate surface portion 240. A first channel 114 is formed between the arcuate surface segment 138 of the second interlocking portion 104 of the first wing portion 108 and the first guiding protrusion 112. When the second interlocking portion 104 of the first wing portion 108 is interlocked with the first interlocking portion 202 of the second wing portion 208, the arcuate surface segment 138 of the second interlocking portion 104 of the first wing portion 108 cooperates / comes into contact with the arcuate surface portion 240 of the first interlocking portion 202 of the second wing portion 208.

[0115] With reference to Figure 14A, when a lifting force F1 is applied to the middle part of the first support beam 100 of the mounting assembly 10, particularly between the two clips 300 (the lifting force F1 can be applied to the first support beam 100 by a photovoltaic panel fixed to the first support beam 100 when an upward wind force acts on the photovoltaic panel, for example), the cooperation / contact between the arcuate surface portion 240 and the arcuate surface section 138, and the engagement between the first groove 134 and the first protrusion 236 can prevent the portion of the second wing 208 inserted into the first channel 114 from sliding out of the first channel 114 at the middle part of the mounting assembly 10 between the two clips 300, thereby preventing the first support beam 100 and the second support beam 200 from moving away from each other.

[0116] Similarly, a second groove 234 is provided on the second guiding protrusion 212 of the second support beam 200, and correspondingly, a second protrusion 136 is provided on the first wing 108 of the first support beam 100. When the first interlocking portion 102 of the first wing 108 is interlocked with the second interlocking portion 204 of the second wing 208, the second groove 234 engages with the second protrusion 136. The first interlocking portion 102 of the first wing 108 has an arcuate surface portion 140, and the second interlocking portion 204 of the second wing 208 has an arcuate surface section 238. A second channel 214 is formed between the arcuate surface section 238 of the second interlocking portion 204 of the second wing 208 and the second guiding protrusion 212. When the first interlocking portion 102 of the first wing 108 is interlocked with the second interlocking portion 204 of the second wing 208, the arcuate surface portion 140 of the first interlocking portion 102 of the first wing 108 cooperates / comes into contact with the arcuate surface section 238 of the second interlocking portion 204 of the second wing 208.

[0117] With reference to Figure 14A , when a lifting force F1 is applied to the middle part of the first support beam 100 of the mounting assembly 10, particularly between the two clips 300, the cooperation / contact between the arcuate surface portion 140 and the arcuate surface section 238, and the engagement between the second groove 234 and the second protrusion 136 can prevent the portion of the first wing 108 inserted into the second channel 214 from sliding out of the second channel 214 at the middle part of the mounting assembly 10 between the two clips 300, thereby preventing the first support beam 100 and the second support beam 200 from moving away from each other.
