[0033] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0034] Reference below Figure 1-Figure 3 A frame assembly 100 according to an embodiment of the present invention is described.

[0035] like Figure 1 and Figure 2 As shown, according to the first embodiment of the utility model, the frame assembly 100 includes: a frame 10 and a mounting pad 20, the frame 10 includes a frame body 11 and a mounting plate 12, the mounting plate 12 is connected to the bottom of the frame body 11, and the mounting plate 12 extends toward the bottom side of the frame body 11, the mounting plate 12 is provided with a mounting hole 121, and the mounting pad 20 includes: a first gasket 21 and a second gasket 22, the first gasket 21 is connected to the second gasket 22, and the first gasket 21 and the second gasket 22 jointly form a mounting groove 2 3. The mounting plate 12 is arranged in the mounting groove 23, the first gasket 21 is arranged above the mounting plate 12, and the first gasket 21 is provided with a first through hole 211, the second gasket 22 is arranged below the mounting plate 12, and the second gasket 22 is provided with a second through hole 221, the first through hole 211, the mounting hole 121 and the second through hole 221 are arranged opposite to each other, wherein the end of the first gasket 21 away from the second gasket 22 is spaced apart from the frame body 11, and the second gasket 22 extends from the bottom of the mounting plate 12 to the bottom of the frame body 11.

[0036] Specifically, traditional frames and purlins are generally fixedly connected by fasteners. Due to the low strength of the frames, there is a risk of cracking of the mounting holes under long-term outdoor use conditions.

[0037] Therefore, the frame assembly 100 is mainly composed of a frame 10 and a mounting pad 20. The mounting plate 12 in the frame 10 is connected to the bottom of the frame body 11, which not only facilitates the fixed installation of the frame 10 and the purlin 25, but also provides support for the frame body 11 and increases the strength of the frame 10.

[0038] Furthermore, the mounting plate 12 is provided with mounting holes 121, which can be conveniently fixedly installed with the purlin 25 and can also be conveniently fixedly connected with the mounting pad 20. The first gasket 21 and the second gasket 22 jointly form a mounting groove 23, and the mounting groove 23 is U-shaped. A portion of the mounting plate 12 containing the mounting hole 121 is located in the mounting groove 23. In this way, a portion of the mounting plate 12 containing the mounting hole 121 is fitted with the first gasket 21 and the second gasket 22. Since the mounting plate 12 is a two-layer structure, a four-layer structure is formed, thereby further increasing the strength of the mounting position of the frame 10 and the purlin 25.

[0039] Moreover, the first gasket 21 is located above the mounting plate 12, so that it can protect the upper surface of the mounting plate 12, and the second gasket 22 is located below the mounting plate 12, so that it can protect the lower surface of the mounting plate 12. The first gasket 21 is provided with a first through hole 211, and the second gasket 22 is provided with a second through hole 221. The first through hole 211, the mounting hole 121, and the second through hole 221 are arranged oppositely, so that it is not only convenient to insert the fastener, but also the thickness of the overall edge of the first through hole 211, the mounting hole 121, and the second through hole 221 can be increased, so that the strength at the mounting hole 121 can be increased.

[0040] Furthermore, the end of the first gasket 21 away from the second gasket 22 is spaced apart from the frame body 11, which can facilitate the maintenance and replacement of the mounting gasket 20, and can also facilitate installation and removal. Moreover, the second gasket 22 extends from the bottom of the mounting plate 12 to the bottom of the frame body 11, which can not only increase the strength of the mounting plate 12 and reduce the risk of fatigue fracture, but also further increase the strength of the bottom of the frame 10, thereby improving the service life of the frame 10.

[0041] Therefore, the frame assembly 100 can increase the thickness of the overall edge of the first perforation 211, the mounting hole 121 and the second perforation 221, increase the strength at the mounting hole 121, and also increase the strength at the mounting plate 12, thereby reducing the risk of fatigue fracture, and further increasing the strength of the bottom of the frame 10, thereby improving the service life of the frame 10.

[0042] According to some embodiments of the present invention, Figure 3 As shown, the width of the first gasket 21 is d1, the width of the second gasket 22 is d2, the width of the mounting plate 12 is d3, and d1, d2 and d3 satisfy the relationship: 0.7d3≤d1<d3<d2.

[0043] The width of the second gasket 22 is greater than the width of the first gasket 21, which is not only convenient for bending and has the advantage of simple processing, but also can avoid stress concentration at the bending point. In addition, the second gasket 22 can also increase the strength of the bottom of the frame 10, and the width of the first gasket 21 is at least greater than the width of a portion of the mounting plate 12 containing the mounting hole 121, thereby increasing the strength at the mounting hole 121 and preventing the mounting hole 121 from tearing.

[0044] According to some embodiments of the present invention, Figure 2 As shown, the second gasket 22 extends from one end of the mounting plate 12 away from the frame body 11 to one end of the bottom of the frame body 11 away from the mounting plate 12 .

[0045] Among them, the second gasket 22 is in full contact with the bottom of the frame body 11, which can not only increase the contact area and improve the stability of the frame 10 installed on the purlin 25, but also increase the thickness of the bottom of the frame 10, thereby improving the strength of the bottom of the frame 10.

[0046] According to some embodiments of the present invention, Figure 1 and Figure 3 As shown, the mounting pad 20 further includes: an arc transition portion 24 , the arc transition portion 24 is connected between the first gasket 21 and the second gasket 22 , and the arc transition portion 24 is bent into an arc shape.

[0047] The arc transition portion 24 is bent into an arc shape, which can make the stress distribution of the transition portion more uniform, avoid stress concentration, and thus improve the strength and durability of the mounting pad 20. Moreover, the arc transition portion 24 is bent into an arc shape, which can avoid the appearance of sharp angles, prevent collisions at sharp angles, and reduce the risk of injury to the human body and equipment, thereby improving safety and reliability.

[0048] According to some embodiments of the present invention, the thickness of the first gasket 21 is h1, h1 satisfies the relationship: 0.6mm≤h1≤1.5mm, and / or the thickness of the second gasket 22 is h2, d satisfies the relationship: 0.6mm≤h2≤1.5mm.

[0049] The thickness of the first gasket 21 can be set to 1 mm, and the thickness of the second gasket 22 can also be set to 1 mm. In this way, the first gasket 21 and the second gasket 22 can be bent into a steel structure, which not only facilitates the rapid prototyping of the first gasket 21 and the second gasket 22 as a whole, but also has the advantage of lightweight design. Moreover, the thickness of the first gasket 21 and the second gasket 22 can also be adjusted according to the thickness of the frame 10.

[0051] The frame body 11 is mainly composed of an outer frame 110, a first inner frame 111 and a second inner frame 115. The first inner frame 111 is formed with a receiving groove to facilitate the installation of the photovoltaic panel.

[0052] In addition, the bottom of the second inner frame 115 and the bottom of the outer frame 110 are both connected to the mounting plate 12 , so that a two-layer structure can be formed at the mounting plate 12 , thereby increasing the strength of the mounting plate 12 .

[0053] Furthermore, a bite structure 30 is provided at the connection between the first inner frame 111 and the second inner frame 115 , so as to prevent the connection between the first inner frame 111 and the second inner frame 115 from being loosened.
