Furthermore, it is required that the present application be understood, not simply by the actual terms used but by the meaning of each term lying within.

The mounting member for a photovoltaic module of the present application will be described with reference to specific examples.

Fig. 1 is a schematic perspective view of a photovoltaic module according to an embodiment of the present application, and fig. 2 is a schematic cross-sectional view taken along line A-A in fig. 1. Referring to fig. 1 and 2, the mount 100 has a body 110, a ball fixture 120, a mount 130, a first damping member 140, and a second damping member 150.

Fig. 3 is a schematic perspective view of a main body according to an embodiment of the present application, and fig. 4 is a schematic front view of the main body in fig. 3. Referring to fig. 3 and 4, the body 110 has a receiving chamber 111 extending in a first direction D1, the receiving chamber 111 having an opening 112 and a bottom plate 113 opposite in the first direction D1, and a first window 114 and a second window 115 opposite in a second direction D2.

In one embodiment, the first window 114 is a bar-shaped window extending along the first direction D1, and "bar-shaped window" refers to a window having a dimension L1 along the first direction D1 that is greater than a dimension W1 along the second direction D2. Similarly, the second window 115 may be a bar-shaped window extending in the first direction D1. The present application does not limit the dimension L1 of the bar window in the first direction D1. As shown in connection with fig. 1, providing the first window 114 and the second window 115 as bar-shaped windows extending in the first direction D1 facilitates an increased travel of the rope 10 moving in the first direction D1, which will be unfolded later. It should be understood that the mount of the present application does not include the cord 10 of fig. 1 and 2, and that the description applies equally hereinafter.

Further, referring to fig. 1 and 3, the ball clamp 120 can be placed into the accommodating chamber 111 from the opening 112, and the dimensional relationship of the ball clamp 120 with the first window 114 and the dimensional relationship of the ball clamp 120 with the second window 115 satisfy the requirement that the ball clamp 120 cannot be detached from the accommodating chamber 111 from the first window 114 and the second window 115, i.e., that the ball clamp 120 cannot be detached from the accommodating chamber 111 from the first window 114 and the second window 115 when the ball clamp 120 is located inside the accommodating chamber 111. The spherical jig 120 may be implemented as a sphere, but may be implemented as a spheroid, for example, a spheroid polyhedron, or may be implemented as an olive.

A schematic perspective view of a ball clamp as described with reference to figure 5. The ball jig 120 has a through hole 121. As shown in fig. 1, the ball clamp 120 may be connected to the rope 10 through a through hole 121. A non-limiting example of the manner in which the ball-shaped clamp 120 is attached to the rope 10 is given here.

Referring to fig. 5, in example one, the spherical clamp 120 has a first hemispherical clamp 122 and a second hemispherical clamp 123, and the through hole 121 penetrates the center of the sphere of the spherical clamp 120. The first hemispherical clamp 122 and the second hemispherical clamp 123 bisect the through hole 121 in the axial direction of the through hole 121.

Next, refer to the perspective schematic view of the hemispherical chuck shown in fig. 6. The first hemispherical clamp 122 has a mounting hole 122a and a mounting hole 122b. The mounting holes 122a and 122b are distributed on both sides of the through hole 121. It should be understood that only a portion of the through holes 121 are shown in fig. 6 for picture reasons. Similarly, the second hemispherical chuck 123 also has mounting holes. Referring to fig. 5, the first hemispherical clamp 122 and the second hemispherical clamp 123 are bolted through the above-mentioned mounting holes. Further, in example one, the diameter of the through hole 121 is smaller than the diameter of the rope passing through the through hole 121, and thus, after the first hemispherical clamp 122 and the second hemispherical clamp 123 are bolted, the rope is fixedly clamped in the through hole 121. In other words, there is an interference fit between the ball clamp 120 and the cord.

It should be noted that the connection manner between the spherical clamp and the rope in the present application is not limited to example one. For example, a blocking member may be provided on the rope located on both sides of the through hole, the blocking member being capable of blocking the rope from moving in the through hole in the axial direction of the through hole. Thereby realizing the effect of the fixed connection of the spherical clamp and the rope in the first example.

Referring to fig. 1 and 3, the mounting seat 130 is disposed at an end of the body 110 away from the bottom plate 113 of the body 110 in the first direction D1, and covers the opening 112 of the body 110. Referring to the perspective schematic view of the mount shown in fig. 7, the mount 130 has a recess 131, and the recess 131 is composed of four side plates (131 a, 131b, 131c, and 131 d) connected in sequence and a top plate 131e connected to top edges of the four side plates. Opposite side edges (131 b and 131D) of the recess 131 in the second direction D2 have two mounting holes 131f, respectively. Referring to fig. 3, the opposite sides of the body 110 in the second direction D2 also have mounting holes 116. The mount 130 and the body 110 are bolted together through the mounting holes described above; after bolting, the recess 131 of the mounting seat 130 covers an end of the main body 110 remote from the bottom plate 113 in the first direction D1, thereby achieving the effect that the mounting seat 130 covers the opening 112 of the main body 110.

Referring to fig. 7, the top plate 131e extends to both sides in the second direction D2, forming a first mounting plate 132 and a second mounting plate 133, respectively, and the first mounting plate 132 and the second mounting plate 133 have mounting holes 132a and 133a, respectively. The mounting holes 132a and 133a are used for connection with the photovoltaic module. It should be understood that the number and location of mounting holes for connection with the photovoltaic module is not limited to the embodiment of fig. 7.

In some embodiments, a first stiffener 134 is disposed between the first mounting plate 132 and the side plate 131 d. Similarly, a second reinforcing rib 135 is also provided between the second mounting plate 133 and the side plate 131 b. The strengthening rib can provide the support for the mounting panel to guarantee that the mounting panel can provide sufficient holding power for photovoltaic module.

Furthermore, in some embodiments, the mounting base 130 does not have the first and second mounting plates 132, 133 shown in fig. 7, the top plate 131e is implemented as a mounting plate, and a number of mounting holes for connection with the photovoltaic module are provided on the top plate 131 e.

Referring to fig. 2, a first damping member 140 is disposed between the base plate 113 and the ball jig 120, and a second damping member 150 is disposed between the mount 130 and the ball jig 120. The two ends of the first damping member 140 may be fixedly connected to the bottom plate 113 and the spherical clamp 120, respectively, or may not be fixedly connected to the bottom plate 113 and the spherical clamp 120; the two ends of the second damping member 150 may be fixedly connected to the mounting base 130 and the ball fixture 120, respectively, or may not be fixedly connected to the mounting base 130 and the ball fixture 120.

The first and second damping members 140 and 150 have elasticity to provide a cushion for the relative movement between the ball clamp 120 and the body 110. Specifically, referring to fig. 2, when the photovoltaic module receives an external force in the first direction D1, the external force is transmitted to the body 110 through the mounting base 130, and the body 110 moves in the first direction D1 with respect to the ball jig 120 under the external force. At this time, the second damping member 150 between the ball jig 120 and the mount 130 may apply an elastic force opposite to the moving direction thereof to the ball jig 120, thereby providing a cushion for the photovoltaic module. In addition, if both ends of the first damping member 140 are fixedly coupled to the ball jig 120 and the base plate 113, respectively, the first damping member 140 may apply a tensile force to the ball jig 120 in a direction opposite to a moving direction thereof. Similarly, when the rope 10 moves the ball screw 120 in a direction opposite to the first direction D1, the first damping member 140 may apply the same elastic force to the ball screw 120 as the moving direction thereof.

As shown in connection with fig. 2 and 4, the dimensions L1 of the first window 114 and the second window 115 in the first direction D1 may be set as desired. Increasing the dimension L1 can increase the travel of the rope 10 moving in the first direction D1, thereby increasing the cushioning travel of the damping member. In fig. 2, the first and second damping members 140 and 150 are implemented as springs, and in other embodiments, the first and second damping members may also be implemented as rubber stoppers.

The damping piece is arranged to play a role in buffering external force applied to the photovoltaic module, so that vibration of the photovoltaic module or a rope is eliminated, and the frame of the photovoltaic module is prevented from being torn due to the external force.

In one embodiment, referring to fig. 2, a dimension L3 of the ball fixture 120 in the second direction D2 is greater than a dimension L2 of the body 110 in the second direction D2. Referring to the perspective view of the photovoltaic module shown in fig. 8, when an asymmetric external force acts on the photovoltaic module, the photovoltaic module rotates, and the external force is transmitted to the main body 110 through the mounting base 130, so that the main body 110 and the spherical clamp 120 rotate relatively, as shown in fig. 8. As shown in fig. 2, when the body 110 and the ball jig 120 are relatively rotated, a portion of the outer surface of the ball jig 120 is in contact with the first and second windows 114 and 115, but is not separated from the receiving cavity 111 from the first and second windows 114 and 115. When the photovoltaic module rotates, the spherical clamp and the main body synchronously rotate, so that the space adaptability of the photovoltaic module is improved. Therefore, even if the photovoltaic modules are not located on the same plane, the photovoltaic modules can be adjusted in a self-adaptive manner through rotation of the main body, so that hidden cracks caused by inconsistent planes between the photovoltaic modules are reduced.

Another aspect of the present application also proposes a photovoltaic bracket comprising the mount as described above. The photovoltaic bracket will be described next.

Fig. 9 is a schematic perspective view of a photovoltaic bracket according to an embodiment of the present application, and fig. 10 is a partially enlarged view of a circular frame portion in fig. 9. As shown with reference to fig. 9, the photovoltaic bracket 200 includes the mount 100 and the cord 210 as previously described. As shown in fig. 1, each rope 210 passes through a through hole of the corresponding spherical clamp 120 to be fixedly connected with the spherical clamp 210, and the photovoltaic module 20 is connected with the mounting seat 130. In fig. 9, the photovoltaic module 20 is supported by two ropes, the number of which is not limited to two in fig. 9, and the number of ropes may be set as required. For example, in one embodiment, the number of ropes is any number equal to or greater than 2, and the ropes may be implemented as steel strands having high strength.

It should be understood that the photovoltaic module 20 in fig. 9 and 10 is for illustration of the photovoltaic bracket of the present application, and does not form part of the photovoltaic bracket.

As shown in connection with fig. 7 and 10, the photovoltaic module 20 is connected to a second mounting plate 133, and the first mounting plate 132 may be used to connect other photovoltaic modules.

As can be seen from the foregoing description of the mounting bracket, referring to fig. 2 and 10, the body 110 is capable of moving relative to the ball clamp 120 under the influence of an external force. In this way, the movement of the photovoltaic module 20 can be buffered, and the vibration of the photovoltaic module 20 or the rope 210 can be eliminated; the stress concentration of the frame of the photovoltaic module 20 caused by external force can be reduced, and the frame of the photovoltaic module 20 is prevented from being torn due to the stress concentration. In addition, the body 110 can also rotate around the ball clamp 120. In this way, when the photovoltaic module 20 rotates, the spherical clamp 120 and the main body 110 rotate synchronously, thereby improving the space adaptability of the photovoltaic module 20. Even if the photovoltaic modules 20 are not located on the same plane, the photovoltaic modules 20 can be adjusted in a self-adaptive manner through the rotation of the main body 110, so that hidden cracks caused by inconsistent planes among the photovoltaic modules are reduced.
