[0031] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0032] See Figure 1 and Figure 4 The photovoltaic support provided in one embodiment of the present application includes a fixing assembly 10, a photovoltaic assembly 20 and a purlin 30. The photovoltaic assembly 20 includes a solar cell 22 and a frame 21. The solar cell 22 is fixedly connected to the frame 21, and the frame 21 is fixed to the purlin 30 through the fixing assembly 10.

[0033] Specifically, the frame 21 has an inner side and an outer side, wherein the inner side refers to the side of the frame 21 connected to the solar cell 22, and the outer side refers to the side of the frame 21 away from the solar cell 22. Figure 2 、 Figure 3 and Figure 4 A fixing portion 211 is provided on the inner side of the frame 21 . The fixing portion 211 is provided with a fixing hole 2111 . Part of the fixing assembly 10 is disposed in the fixing hole 2111 to fix the frame 21 to the purlin 30 .

[0034] It should be noted that the position of the fixing portion 211 can be set according to actual needs. Figure 2 The fixing portion 211 is provided on the inner side of the long side of the frame 21. Alternatively, the fixing portion 211 is provided on the inner side of the short side of the frame 21; or, the fixing portion 211 is provided on the inner side of both the long side and the short side of the frame 21.

[0035] In one embodiment, see Figure 6 and Figure 7 The fixing assembly 10 includes a cushion 11. The cushion 11 includes a first clamping portion 111 and a second clamping portion 112 arranged opposite to each other. The first clamping portion 111 and the second clamping portion 112 have a first side. The first side of the first clamping portion 111 is connected to the first side of the second clamping portion 112. The first clamping portion 111 and the second clamping portion 112 cooperate to clamp the area where the fixing hole 2111 is located. The first clamping portion 111 is provided with a first through hole 1111, and the second clamping portion 112 is provided with a second through hole 1121. The first through hole 1111 is connected to the second through hole 1121.

[0036] Further, see Figure 6 and Figure 7The fixing assembly 10 further includes a locking member 12. Optionally, the locking member 12 is a bolt or the like. The locking member 12 is used to be disposed in the fixing hole 2111, the first through hole 1111, and the second through hole 1121 to fix the frame 21 to the purlin 30.

[0037] When installing the aforementioned fixing assembly 10, the gasket 11 is first mounted on the fixing portion 211. The first clamping portion 111 and the second clamping portion 112 cooperate to clamp the area where the fixing hole 2111 is located. After the gasket 11 is mounted on the fixing portion 2111, the fixing hole 2111 communicates with the first through-hole 1111 and the second through-hole 1121. The locking member 12 is then positioned within the fixing hole 2111, the first through-hole 1111, and the second through-hole 1121 to secure the frame 21 to the purlin 30. Since the first clamping portion 111 and the second clamping portion 112 wrap the area where the fixing hole 2111 is located, the first clamping portion 111 and the second clamping portion 112 form surface contact with the area where the fixing hole 2111 is located. In this way, the cushion 11 can transfer the load to the surroundings, so that the stress distribution is uniform, and the load borne by the area where the fixing hole 2111 is located is reduced, thereby avoiding the phenomenon of tensile failure of the fixing portion 211 and ensuring the reliability of the frame 21 being fixed to the purlin 30.

[0038] In one embodiment, see Figure 4 and Figure 7 The first clamping portion 111 and the second clamping portion 112 are connected to form a clamping groove 113, and the clamping groove 113 is inserted into the fixing portion 211. During installation, the notch of the clamping groove 113 is aligned with the fixing portion 211, and an external force is applied to the cushion 11, so that the fixing portion 211 is inserted into the clamping groove 113.

[0039] In one embodiment, the first clamping portion 111 further has a second side, and the first side and the second side of the first clamping portion 111 are arranged opposite to each other.

[0040] Further, see Figure 4 and Figure 7 The second side of the first clamping portion 111 is provided with a hook 1112, which is used to hook onto the outer side of the frame 21. It is understood that the second side of the first clamping portion 111 is provided with a chamfered corner that curves toward the second clamping portion 112 to form the hook 1112. During installation, after the first clamping portion 111 and the second clamping portion 112 engage the area where the fixing hole 2111 is located, the hook 1112 hooks onto the outer side of the frame 21. This facilitates alignment and installation.

[0041] In one embodiment, the second clamping portion 112 further has a second side, and the first side and the second side of the second clamping portion 112 are disposed opposite to each other.

[0042] Further, see Figure 2 、 Figure 3 、 Figure 5 and Figure 6 A positioning portion 114 is provided on the second side of the second clamping portion 112. The positioning portion 114 extends away from the first clamping portion 111 and is positioned and engaged with the inner side of the frame 21. During installation, the positioning portion 114 is positioned and engaged with the inner side of the frame 21, allowing the fixing hole 2111 to communicate with the first through-hole 1111 and the second through-hole 1121, thereby facilitating the installation of the locking member 12. Furthermore, the positioning portion 114 is positioned and engaged with the inner side of the frame 21, thereby enhancing the mechanical properties of the frame 21.

[0043] In one embodiment, see Figure 3 、 Figure 5 and Figure 6 A positioning protrusion 1141 is provided on the side of the positioning portion 114 facing away from the second clamping portion 112. Positioning protrusion 1141 is configured to fit within a positioning hole 212 on the inner side of the frame 21. Optionally, positioning protrusion 1141 is a rivet or the like. During installation, after the first clamping portion 111 and the second clamping portion 211 are engaged with each other, positioning protrusion 1141 fits within the positioning hole 212 of the frame 21, effectively positioning the two. This improves the convenience of positioning the cushion 11 and the frame 21.

[0044] Of course, in other embodiments, the positioning portion 114 may also be provided with a positioning hole 212, and the inner side of the frame 21 may be provided with a positioning protrusion 1141. Alternatively, the positioning portion 114 may be provided with a positioning hook that engages with the positioning hole 212 of the frame 21 to achieve positioning of the two. Alternatively, the positioning portion 114 may be provided with a first magnetic member, and the frame 21 may be provided with a second magnetic member, and the first magnetic member and the second magnetic member may be magnetically engaged.

[0045] It should be noted that the number of positioning protrusions 1141 can be set according to actual needs. Optionally, there is one positioning protrusion 1141. Alternatively, see Figure 3 、 Figure 5 and Figure 7 There are at least two positioning protrusions 1141 , and all positioning protrusions 1141 are arranged in a one-to-one correspondence with all positioning holes 212 , which can improve the reliability of positioning and enhance the mechanical properties of the frame 21 .

[0046] In this embodiment, refer to Figure 3 、 Figure 5 and Figure 7 There are three positioning protrusions 1141, which are arranged side by side. The three positioning protrusions 1141 are arranged in a one-to-one correspondence with the three positioning holes 212.

[0047] In one embodiment, see Figure 7The length of the first clamping portion 111 is greater than the length of the second clamping portion 112. It should be noted that the length of the first clamping portion 111 is the distance between the first side and the second side of the first clamping portion 111, and the length of the second clamping portion 112 is the distance between the first side and the second side of the second clamping portion 112. In this way, on the one hand, it can ensure that the hook 1112 of the first clamping portion 111 can be hooked on the outside of the frame 21, and on the other hand, it can ensure that the positioning portion 114 can be positioned and matched with the inside of the frame 21.

[0048] In one embodiment, see Figure 5 The purlin 30 has a receiving groove 31 , and both groove walls of the receiving groove 31 are provided with folded edges 32 .

[0049] Optionally, see Figure 5 The folded edge 32 includes a supporting portion 321 and a limiting portion 322. The supporting portion 321 extends from the slot opening of the receiving slot 31 to one of the slot walls toward the other opposite slot wall. The supporting portion 321 is configured to contact the first clamping portion 111 to support the cushion 11. The limiting portion 322 extends from the supporting portion 321 toward the bottom of the receiving slot 31. Of course, in other embodiments, the supporting portion 321 may also be located between the slot opening and the slot bottom, or the folded edge 32 may include only the supporting portion 321.

[0050] Further, see Figure 5 and Figure 6 , the fixing assembly 10 also includes a nut 13. The nut 13 is provided with a threaded hole 131, and the locking member 12 is provided in the threaded hole 131 and is threadedly connected to the nut 13. The nut 13 is used to be provided in the receiving groove 31 and contact the folded edge 32. During installation, the frame 21 with the gasket 11 is placed on the purlin 30 so that the first clamping portion 111 contacts the support portion 321. Then, the locking member 12 is provided in the fixing hole 2111, the first through hole 1111 and the second through hole 1121. Then, the nut 13 is provided in the receiving groove 31, and the nut 13 is sleeved on the locking member 12, and the nut 13 is rotated until the nut 13 is released from the folded edge 32. In this way, the frame 21 can be fixed to the purlin 30.

[0051] In one embodiment, see Figure 6 and Figure 8 The nut 13 is provided with an anti-slip portion 132, which is used to contact the folded edge 32. Specifically, the anti-slip portion 132 contacts the limiting portion 322. In this way, the friction between the nut 13 and the limiting portion 322 can be increased, and the reliability of the frame 21 fixation can be improved.

[0052] Optionally, see Figure 8 The anti-slip portion 132 is at least one of an anti-slip groove, an anti-slip protrusion, and an anti-slip tooth.
