Various parameters of the beams 121-1 and 121-2, such as size, shape, component composition, properties, materials, processes, patterns, etc., may be the same or different. The beams 121-1 and 121-2 may be connected to each other, connected to each other by other components, or not connected to each other. The beam 121-1 and the beam 121-2 may be two independent mechanical structures or may be components belonging to the same independent assembly structure. For example, beam 121-1 and beam 121-2 may be two raised structures belonging to the same rigid structure surface. One photovoltaic module 110 may be mounted on only one beam 121, or may be mounted on two or more beams 121 at the same time.

It is noted that fig. 1-a, 1-b and 1-c are merely illustrative and are not intended to be exclusive. The relevant features described for each, as well as some features not directly illustrated, may be present in part or in whole in a photovoltaic power generation system 100.

Fig. 2-a and 2-b are schematic views of an example panel-securing assembly, according to some embodiments of the invention. Fig. 2-a is a schematic front view of the panel mounting assembly 300. Fig. 2-b is a rear view of the panel securing assembly 300. The panel retaining assembly 300 is one specific embodiment of the panel retaining assembly 112 as described in fig. 1-a. The panel mounting assembly 300 may include a panel bezel 310, a base plate 320, and the like. The photovoltaic panel 111 may be mounted on the base plate 320. The panel bezel 310 surrounds the photovoltaic panel 111. The bottom plate 320, the photovoltaic panel 111, and the panel bezel 310 do not require shapes that completely correspond, but only need to satisfy the above relationships. One or more bezel attachment structures 330 may be further included on the panel bezel 310 for securing the panel mounting assembly 300 to the cross member 121. The materials of construction of panel bezel 310, bezel coupling structure 330, and chassis 320 may be the same or different. The connection between panel bezel 310 and base plate 320 and between panel bezel 310 and bezel connection structure 330 may be a connector connection or an integral connection.

Panel bezel 310 may be comprised of one or more bezel members 340, such as bezel members 340-1, 340-2, 340-3, or 340-4. The rim member 340 may be a straight configuration, an arcuate configuration, the like, or a combination thereof. Panel bezel 310 may be comprised of bezel members 340 joined end-to-end. The different frame members 340 that make up panel frame 310 may be made of the same or different materials. In some embodiments, the photovoltaic panel 111 may have a geometry similar to a rectangle, and accordingly, the panel bezel 310 may also be designed as a rectangle, with the bezel members 340-1, 340-2, 340-3, 340-4 representing the four sides of the rectangle, respectively. The names of frame members 340-1, 340-2, 340-3, 340-4 are merely used for identification purposes and may represent any one of the sides of panel bezel 310. for convenience of description, frame members 340-1 and 340-3 represent one pair of axially opposite sides of panel bezel 310, and frame member 340-2 and frame member 340-4 represent another pair of axially opposite sides of panel bezel 310. Wherein the frame member 340-1 includes at least one frame connecting structure 330 and is connected to the beam 121 via the structure. Taking the frame members 340-1 and 340-3 as examples, various parameters, such as size, shape, configuration, material, process, pattern, sub-configuration, number of sub-configurations, etc., may be the same or different. Frame members 340-1 and 340-3 are on either side of base 320 and are connected to base 320. The interconnection between the frame members 340 may include a connector connection, an integral connection, or a combination thereof. For example, the frame members 340-1 and 340-2 may be integrally connected to form an L-shaped member; 340-3 and 340-4 may form another L-shaped member by an integral connection, and the two L-shaped members may be connected together by a connecting member.

It is noted that bezel element 340 represents only one edge of panel bezel 310 in the present invention and does not represent a specific and separate component in an actual application. A separate component in a practical application may be a frame piece 340 or a combination of several frame pieces 340 in the present invention. For example, for a rectangular panel frame 310, although the panel frame 310 includes four sides in total, in practical applications, components representing two or more sides may be integrally formed by bending a straight component or by casting through a special mold. The number of individual components can be less than four. The number of bezel members 340 may be determined according to the geometry of panel bezel 310. For example, hexagonal panel bezel 310 may have six bezel members 340. For convenience of description, the rectangular panel bezel 310 will be described as an example in the present invention, but it is understood that the description does not limit the panel bezel 310 to be rectangular or the number of bezel members 340 to be four.

The frame connecting structure 330 is used to fix the panel mounting assembly 300 to the cross member 121. Bezel attachment structure 330 is located entirely on panel bezel 310. The frame connecting structure 330 may be located on the back or side of the photovoltaic module 110. The size of the frame connecting structure 330 is not particularly limited, and may span the entire one of the frame members 340 or may remain only large enough to connect to the beam 121. In some embodiments, the bezel connecting structure 330 and the beam 121 connected thereto may have complementary cross-sectional shapes at the interface.

The bezel connecting structure 330 may have a portion or the entire area overlying the base plate 320. The frame connecting structure 330 may further include holes, slits, protrusions, grooves, or a combination thereof to enhance the connection with the cross member 121. In some embodiments, the frame connecting structure 330 may be a separate structure that is connected to one of the frame members 340 by using a connecting member, or may be connected to one of the frame members 340 by using an integrated connecting means (e.g., welding, etc.). In some embodiments, the frame attachment structure 330 may be a feature (e.g., a raised structure) on the frame member 340 that is added to the frame member 340 by one or more physical molding methods such as hammering, bending, punching, cutting, etc., or by integrally molding the mold during casting.

In some embodiments, the panel securing assembly 300 may include at least two bezel connecting structures 330, such as bezel connecting structures 330-1 and 330-2. Various parameters of the frame connecting structures 330-1 and 330-2, such as size, shape, structure, material, process, pattern, substructure, number of substructures, etc., may be the same or different. Bezel attachment structure 330-1 and bezel attachment structure 330-2 may be located on two different bezel members 340 (e.g., bezel member 340-1 and bezel member 340-3) or on the same bezel member 340, respectively. The bezel connection structure 330-1 and the bezel connection structure 330-2 may be connected to the same beam 121 or to different beams 121. The specific locations of the bezel attachment structure 330-1 and the bezel attachment structure 330-2 or the relative locations of the two are not particularly required.

The back side of the panel securing assembly 300 may include one or more bezel reinforcing structures 350 (such as the bezel reinforcing structures 350-1 and 350-2 shown in fig. 3-a). The frame reinforcing structure may be used to improve the mechanical strength of the panel securing assembly 300. The bezel reinforcing structure may be coupled to panel bezel 310 and/or base plate 320 and span base plate 320. In some embodiments, the rim reinforcement structure may include one or more lateral reinforcement structures 350-1 and/or one or more longitudinal reinforcement structures 350-2. In some embodiments, the transverse reinforcing structure 350-1 may be a transverse stiffener and the longitudinal reinforcing structure 350-2 may be a longitudinal stiffener. In some embodiments, transverse reinforcing structure 350-1 may be connected to frame members 340-1 and 340-3, and longitudinal reinforcing structure 350-2 may be connected to frame member 340-2 and frame member 340-4.

The material of the backplane connection structure 360 may comprise one or a combination of metals, glasses, ceramics, and/or polymers. The base connection structure 360 may have a similar or different shape or structure as the bezel connection structure 330-3 (or 330-4).

In some embodiments, two or more bezel attachment structures 330, such as bezel attachment structures 330-5, 330-6, 330-7, and 330-8, may be included on each of bezel members 340-1 and 340-3. Various parameters of the bezel connection structures 330-5, 330-6, 330-7, and 330-8, such as size, shape, structure, material, process, pattern, substructure, number of substructures, etc., may be the same or different. In some embodiments, the bezel connection structure 330-5 and the bezel connection structure 330-6 can be connected to the same beam 121, while the bezel connection structure 330-7 and the bezel connection structure 330-8 can be connected to another beam 121. The specific location and relative position of the rim connecting structures 330-5, 330-6, 330-7 and 330-8 on the rim members 340-1 and 340-3 is not particularly required. In some embodiments, the bezel connection structures 330-1, 330-2, 330-3, and 330-4 may be connected to two parallel beams 121.

It is noted that the above exemplary description of the panel securing assembly 300 is not intended to be exhaustive. Their respective described related features, as well as some features not directly illustrated, may be present in part or in whole in a panel retaining assembly 300.

Fig. 5-d is a schematic illustration of an example rigid connection structure, according to some embodiments of the invention.

Fig. 6-a is a schematic illustration of an exemplary panel load module beam connection structure and manner of connection between beams, according to some embodiments of the invention. The beam connection structure may include the bezel connection structure 330 as depicted in fig. 2-a and 2-b, the chassis connection structure 360 as depicted in fig. 3-c, the rigid structural connection layer 510 as depicted in fig. 5-a, and various embodiments of the above. Wherein the cross-section 600 is a cross-section of the beam connection structure at the connection with the beam 121, and the cross-section 680 is a cross-section of the beam 121 on the same plane as the cross-section 600. Connection surface 620 is the surface of the beam connection structure that contacts beam 121, and connection surface 640 is the surface of beam 121 that contacts connection surface 620. In the cross-sectional schematic depicted in fig. 6-a, joint plane 620 and joint plane 640 may be represented by a combination of one or more straight and/or arcuate line segments. After the panel mounting assembly 112 is mounted on the cross member 121, the connection surface 620 and the connection surface 640 may be attached. Cross-section 600 and cross-section 680 may be considered complementary when connecting surface 620 and connecting surface 640 are mated and cross-section 600 and/or cross-section 680 include at least one relief.

The cross-section 680 of the beam 121 may have a variety of different shapes, as described in detail herein with respect to fig. 1-a. In order to enhance the connection effect between the panel loading assembly 112 and the cross beam 121, the cross beam connection structure may be designed to have a complementary cross-sectional shape at the contact surface with the cross beam 121 connected thereto. When the beam 121 has cross-sections 680 of various shapes or sizes on the contact surface, the cross-section 600 of the beam connection structure at the corresponding location may still be complementary thereto. In some embodiments, the cross-section 600 may completely or partially surround the cross-section 680, in which case the connection face 640 may surround or partially surround the cross-section 680.

In some embodiments, the connection surfaces 620 and 640 may further include some textures, concave-convex shapes, connection holes, etc. to enhance the connection effect between the panel fastening assembly 112 and the cross beam 121. Other structures or connectors may be added to the portion other than the connection face 620. For example, a U-shaped structure may be further connected to the beam connecting structure. The U-shaped structure may engage the beam 121 along with the beam connection structure to secure the connection between the panel fastener assembly 112 and the beam 121 without additional physical shaping of the beam, such as punching. One or more connectors, such as a hoop, a bolt, a nut, etc., may be used to fasten the frame connecting structure 330 and/or the cross member 121. In some embodiments, through bolt holes may be included on the beam connection structure and the beam 121, and then the two are fastened with bolts.

It is noted that the cross-section 600 is only a schematic illustration in fig. 6-a and does not limit the actual cross-sectional shape of the beam attachment structure. After the joint plane 620 is defined, the cross-section 600 may be provided in any shape without affecting the mechanical properties of the joint plane 620 and the joint, which may be macroscopically circular or polygonal as defined in the present invention, unless otherwise specified. The cross-section 600 may be concave or convex in shape as shown in fig. 6-a, and accordingly, the cross-section 680 on the beam 121 may include a convex or concave shape that is complementary to the cross-section 600.

In some embodiments, prior to connecting the beam connection structure to beam 121, there may be no complementarity between the original shape between cross-section 600 and cross-section 680; after the beam connection structure and the beam 121 are connected and during normal use of the photovoltaic power generation system 100, the cross section 600 and the cross section 680 become complementary due to deformation of the beam connection structure and/or the beam 121, and the cross section 600 and the cross section 680 can be considered to be complementary. The relevant embodiments of the present invention, both cross-section 600 and cross-section 680, will follow the relevant characteristics as defined hereinabove.

Fig. 6-b is a schematic illustration of an exemplary beam connection structure and connection between beams according to some embodiments of the invention. As shown, the cross-section 681 of the beam 121 may have a square shape, and accordingly, the cross-section 601 of the beam connection structure may include a square groove of a corresponding shape. The cross-section 601 and the cross-section 681 can be complementary when the beam 121 is coupled to the beam coupling structure.

Fig. 6-c illustrate some embodiments of an exemplary beam connection structure and beam 121 connection according to some embodiments of the present invention. As shown, the cross-section 682 of the beam 121 may have a splined or star-shaped configuration, and correspondingly, the cross-section 601 of the beam connection may include a correspondingly shaped spline or star-shaped groove. When beam 121 is coupled to the beam coupling structure, cross-section 602 and cross-section 682 may be complementary. The splines or star-shaped structures on the cross-beam 121 may inhibit the panel load assembly 112 from rotating along the cross-beam 121.
