[0041] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0042] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0043] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the inverter mounting assembly 100 provided in this embodiment from a first-view perspective. Figure 2 This is an exploded view of the inverter mounting assembly 100 provided in this embodiment from a second perspective.

[0044] The inverter mounting assembly 100 includes a frame 110, a heat sink 120, and a connector 130. The frame 110 is used to connect the inverter 230. The heat sink 120 is installed on the side of the frame 110 near the heat dissipation surface 231 of the inverter 230. The connector 130 is connected to the frame 110 and is used to connect the photovoltaic frame 210.

[0045] Specifically, in this embodiment, the connector 130 is a clamping member used to clamp the photovoltaic frame 210. The inverter 230 is connected to the frame 110; in this embodiment, the inverter 230 is connected to the photovoltaic frame 210 through the frame 110 and the connector 130; thus, after the photovoltaic module 220 is installed on the photovoltaic frame 210, the solar energy absorbed by the photovoltaic module 220 can be converted into electrical energy by the inverter 230, and the installation stability of the inverter 230 can be provided to prevent the inverter 230 from detaching from the photovoltaic frame 210.

[0046] Understandably, the inverter 230 includes multiple electrical components. During the operation of these components, heat dissipation is required for the inverter 230. Therefore, one side of the inverter 230 is a heat dissipation surface 231. In this embodiment, a heat sink 120 is installed on the frame 110, and the heat sink 120 is positioned close to the heat dissipation surface 231, thereby improving the heat dissipation effect of the inverter 230 and extending its service life.

[0047] Further, please refer to Figure 1 and Figure 2 The frame 110 includes a support bracket 111, a connecting bracket 112, and a mounting bracket 113. The support bracket 111 is connected to the connecting bracket 112 and the mounting bracket 113 to form a receiving slot 101, which is used to receive the inverter 230. The connecting bracket 112 and the mounting bracket 113 are located on opposite sides of the inverter 230. The connecting bracket 112 is connected to the connector 130, and the mounting bracket 113 is equipped with a heat sink 120.

[0048] Specifically, in this embodiment, the connecting bracket 112, the supporting bracket 111, and the mounting bracket 113 are connected to each other to form a "C" shape, thereby forming a receiving groove 101 for receiving the inverter 230. The supporting bracket 111 is located below the inverter 230 to provide support for the inverter 230, and the connecting bracket 112 is connected to the clamping member, so that the inverter 230 can be connected to the photovoltaic frame 210.

[0049] It should be noted that the clamping member is connected to the photovoltaic frame 210 because the position of the connecting plate is close to the photovoltaic frame 210. If the heat dissipation surface 231 of the inverter 230 is close to the connecting plate, the heat dissipated by the inverter 230 will be released to the photovoltaic module 220 installed on the photovoltaic frame 210, affecting the power generation efficiency of the photovoltaic module 220.

[0050] Therefore, in this embodiment, the heat dissipation surface 231 should be away from the connecting bracket 112. In addition, a heat dissipation member 120 is installed on the mounting bracket 113. Therefore, the connecting bracket 112 and the mounting bracket are respectively arranged on opposite sides of the inverter 230, so that the heat dissipation surface 231 of the inverter 230 is away from the connecting bracket 112 and close to the heat dissipation member 120 on the mounting bracket, thereby improving the heat dissipation efficiency of the inverter 230 and avoiding affecting the power generation efficiency of the photovoltaic module 220.

[0051] According to the above structural arrangement, in this embodiment, the mounting bracket 113 is provided with a plurality of mounting holes 114; the heat dissipation member 120 includes a plurality of heat dissipation fans 121; the plurality of mounting holes 114 are arranged at intervals along the length direction of the mounting bracket 113; the plurality of heat dissipation fans 121 correspond to the plurality of mounting holes 114 one by one; each heat dissipation fan 121 is movably arranged in the corresponding mounting hole 114.

[0052] Specifically, in this embodiment, the mounting bracket 113 includes a plurality of crosses, each cross is arranged in a mounting hole 114, and each cross is movably connected to the corresponding heat dissipation fan 121, so that the heat dissipation fan 121 can rotate around the axis of the mounting hole 114, thereby accelerating the air flow and improving the heat dissipation efficiency.

[0053] There is a gap between the cross and the inner wall of the mounting hole 114, so that the heat in the inverter 230 can flow to the mounting hole 114 through the air and flow to the outside through the mounting hole 114, thereby achieving heat dissipation.

[0054] In other embodiments, the number of the heat dissipation fans 121 and the mounting holes 114 can also be one, and the number of the heat dissipation fans 121 and the mounting holes 114 can be adjusted according to the actual heat dissipation situation of the inverter 230.

[0055] Please refer to Figures 1-4 , Figure 3This is a schematic diagram of the structure of the first clamping wall 131 provided in this embodiment; Figure 4 This is a schematic diagram of the structure of the second clamping wall 132 provided in this embodiment.

[0056] The connector 130 includes a first clamping wall 131 and a second clamping wall 132. The first clamping wall 131 is provided with a first mounting hole 1311, and the second clamping wall 132 is provided with a second mounting hole 1321. The inverter mounting assembly 100 also includes a connecting shaft 140 and a movable collar 150. One end of the connecting shaft 140 is connected to the frame 110, and the other end of the connecting shaft 140 passes through the first mounting hole 1311, the second mounting hole 1321, and the movable collar 150 in sequence. The connecting shaft 140 is movably engaged with the first clamping wall 131 and the second clamping wall 132, and is threadedly engaged with the movable collar 150. When the movable collar 150 moves along the axial direction of the connecting shaft 140 toward the position of the frame 110, the movable collar 150 drives the second clamping wall 132 to approach the first clamping wall 131 to clamp the photovoltaic frame 210.

[0057] Understandably, in this embodiment, the connector 130 is a clamping member, wherein the first clamping wall 131 and the second clamping wall 132 are both sleeved on the connecting shaft 140, and one end of the connecting shaft 140 is connected to the connector 130. When it is necessary to clamp the clamping member to the photovoltaic frame 210 and fix it, the movable collar 150 is rotated so that the movable collar 150 moves closer to the connecting bracket 112 along the axial direction of the connecting shaft 140.

[0058] During installation, the wire abuts the first clamping wall 131 against the connecting bracket 112, and then abuts the photovoltaic frame 210 against the first clamping wall 131. Since the first clamping wall 131 and the second clamping wall 132 are located between the movable collar 150 and the connecting bracket 112, as the movable collar 150 moves toward the connecting bracket 112, the second clamping wall 132 will contact the movable collar 150 and move toward the connecting bracket 112 along with the movable collar 150. This causes the second clamping wall 132 to gradually approach and contact the photovoltaic frame 210. Furthermore, under the action of the movable collar 150, the second clamping wall 132 continues to approach the first clamping wall 131 to cooperate with the first clamping wall 131 to clamp the photovoltaic frame 210.

[0059] Similarly, during the disassembly process, the movable collar 150 is rotated to move it away from the connecting bracket 112, and then the second clamping wall 132 is moved away from the first clamping wall 131 to widen the gap and remove the photovoltaic frame 210.

[0060] Therefore, in this embodiment, the movable collar 150 moves the second clamping wall 132 and the first clamping wall 131 closer or further apart to clamp the photovoltaic frame 210, thereby enabling the photovoltaic frame 210 and the frame 110 to be installed together or detached. The clamping action of the first clamping wall 131 and the second clamp on the photovoltaic frame 210 ensures the connection stability between the frame 110 and the photovoltaic frame 210, thus ensuring the installation stability of the inverter 230.

[0061] In other embodiments, the connector 130 may also be a plate-like structure, which connects the bracket 112 and the photovoltaic frame 210 by bolts. Again, the specific shape of the connector 130 is not limited.

[0062] In other embodiments, the connector 130 may also be a snap-fit ​​connector, and snap-fit ​​holes are provided on the photovoltaic frame 210 to snap the connector and snap-fit ​​holes together, thereby connecting the inverter 230 and the photovoltaic frame 210 together, thereby improving the stability of the installation.

[0063] Based on the above, please refer to... Figures 1-4 In this embodiment, a first positioning pin 133 is provided on the inner side of the first clamping wall 131, and a second positioning pin 134 is provided on the inner side of the second clamping wall 132; one of the first positioning pin 133 and the second positioning pin 134 is provided with a positioning groove 135, and the other cooperates with the positioning groove 135.

[0064] Specifically, the first positioning pin 133 is disposed on the inner side of the first clamping wall 131, and the second positioning pin 134 is disposed on the inner side of the second clamping wall 132. As the second clamping wall 132 approaches the first clamping wall 131, the first positioning pin 133 and the second positioning pin 134 will first contact and abut, so that when the first clamping wall 131 approaches the first clamping wall 132, there is no gap between the first clamping wall 131 and the second clamping wall 132 to place the photovoltaic frame 210 and clamp the photovoltaic frame 210.

[0065] In this embodiment, the first positioning pin 133 is provided with a positioning groove 135. As the second clamping wall 132 approaches the first clamping wall 131, the second positioning pin 134 can gradually enter the positioning groove 135, thereby positioning the clamping positions of the first clamping wall 131 and the second clamping wall 132, ensuring the stability of clamping, and thus ensuring the installation stability of the inverter 230.

[0066] This embodiment also includes an abutment 138 disposed on the inner side of the second clamping wall 132 to prevent the first clamping wall 131 and the second clamping wall 132 from fitting together, so that there is a gap between the first clamping wall 131 and the second clamping wall 132.

[0067] In other embodiments, the second positioning pin 134 is provided with a positioning groove 135, and the first positioning pin 133 can gradually enter the positioning groove 135 as the second clamping wall 132 approaches the first clamping wall 131.

[0068] In other embodiments, a positioning groove 135 is provided on the inner side of the first clamping wall 131 and the inner side of the second clamping wall 132, and a positioning protrusion is provided on the other side; the positioning groove 135 cooperates with the positioning protrusion; the opening direction of the positioning groove 135 and the protrusion direction of the positioning protrusion are both parallel to the axial direction of the connecting shaft 140; wherein, the groove depth of the positioning groove 135 is less than the thickness of the positioning protrusion.

[0069] Understandably, the first clamping wall 131 is provided with a positioning groove 135, while the second clamping wall 132 is provided with a positioning protrusion, so that as the second clamping wall 132 approaches the second clamping wall 132, the positioning protrusion can gradually enter the positioning groove 135.

[0070] In order to ensure that there is still a gap between the first clamping wall 131 and the second clamping wall 132 after the second clamping wall 132 can no longer approach the first clamping wall 131, the groove depth of the positioning groove 135 is less than the thickness of the positioning protrusion, so that at least part of the positioning protrusion is always located outside the positioning groove 135.

[0071] Further, please refer to Figures 1-4 The connector 130 also includes a first anti-slip member 136 and a second anti-slip member 137. The first anti-slip member 136 is disposed on the inner side of the first clamping wall 131, and the second anti-slip member 137 is disposed on the inner side of the second clamping wall 132. Both the first anti-slip member 136 and the second anti-slip member 137 are used to abut against the photovoltaic frame 210.

[0072] Specifically, in this embodiment, a first anti-slip member 136 and a second anti-slip member 137 are respectively provided on the inner side of the first clamping wall 131 and the inner side of the second clamping wall 132 to increase friction. Understandably, the surfaces of the first anti-slip member 136 and the second anti-slip member 137 are relatively rough, thereby increasing the friction between them and the photovoltaic frame 210, thus improving installation stability and preventing the inverter mounting assembly 100 from detaching from the photovoltaic frame 210.

[0073] According to the above, the frame 110 is provided with a third mounting hole 115; one end of the connecting shaft 140 is provided with a stop part 141; the other end of the connecting shaft 140 passes through the third mounting hole 115; the stop part 141 abuts against the frame 110.

[0074] Understandably, in this embodiment, the connecting shaft 140 and the movable collar 150 are bolts and nuts. In this embodiment, the threaded engagement of the bolts and nuts drives the second clamping wall 132 to approach the first clamping wall 131 to clamp the photovoltaic frame 210, thereby enabling the inverter mounting assembly 100 to connect the inverter 230 and the photovoltaic frame 210 together to ensure the installation stability of the inverter 230.

[0075] Please refer to Figures 1-6 , Figure 5 This is a schematic diagram of the photovoltaic system 200 from a first-view perspective provided in this embodiment; Figure 6 This is a schematic diagram of the photovoltaic system 200 from a second perspective provided in this embodiment.

[0076] This utility model provides a photovoltaic system 200, which includes a photovoltaic frame 210, a photovoltaic module 220, an inverter 230, and an inverter mounting assembly 100. The photovoltaic module 220 is connected to the photovoltaic frame 210. The inverter 230 is connected to the frame 110 through the inverter mounting assembly, and the inverter 230 is located on the back of the photovoltaic module 220.

[0077] It should be noted that the photovoltaic module 220 in this embodiment includes a photovoltaic panel and laminates, etc. In order to avoid the inverter 230 from shading the photovoltaic panel and to avoid the inverter 230 from affecting the power generation and power generation efficiency of the photovoltaic panel, the inverter 230 needs to be installed on the back of the photovoltaic panel.

[0078] In other embodiments, the photovoltaic system 200 includes a photovoltaic frame 210, a photovoltaic module 220, and an inverter 230, with the photovoltaic frame 210 and the photovoltaic module 220 connected together; the photovoltaic frame 210 is provided with a snap-fit ​​hole, and the inverter 230 is provided with a snap-fit ​​component, which snaps into the snap-fit ​​hole.

[0079] The snap-fit ​​hole has a first part and a second part, and the snap-fit ​​part has a limiting part and a mating part. The diameter of the first part in the vertical direction is larger than the diameter of the second part in the vertical direction, so that the limiting part can pass through the first part, and after the mating part moves from the first part to the second part, the limiting part cannot pass through the second part, thereby snapping the inverter 230 and the photovoltaic frame 210 together.

[0080] In summary, the inverter mounting assembly 100 includes a frame 110, a heat sink 120, and a connector 130. The frame 110 is used to connect the inverter 230. The heat sink 120 is installed on the side of the frame 110 near the heat dissipation surface 231 of the inverter 230. The connector 130 is connected to the frame 110 and is used to connect the photovoltaic frame 210, thereby improving the installation stability of the inverter 230 and preventing the inverter 230 from detaching from the photovoltaic frame 210 due to unstable installation. At the same time, by setting the heat sink 120, the heat dissipation effect of the inverter 230 is improved, and the service life of the inverter 230 is extended.

[0081] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
