The photovoltaic modules 200 are fixed to the color steel tile roof 300 through the fixed structure 100, which is simple to assemble and reduces labor costs.

[0036] Please refer to Figures 1 to 5The utility model discloses a fixing structure 100, which is used to fix the photovoltaic module 200 to the color steel tile roof 300. The color steel tile roof 300 is provided with a plurality of parallel clamping protrusions 310. The fixing structure 100 includes a clamping assembly 1, a pressure block 2 and a second fastener 3. The clamping assembly 1 is clamped on the clamping protrusion 310, and the clamping assembly 1 includes a first clamping member 11, a second clamping member 12 and a first fastener 13. The first clamping member 11 includes a base 111, an abutting portion 112 arranged at the center of the base 111 and a fixing portion 113 arranged at the edge of the base 111, the abutting portion 112 abuts against the roof, and a rotating portion 114 is provided on the base 111, and the rotating portion 114 is arranged between the abutting portion 112 and the fixing portion 113. One end of the second clamping member 12 is rotatably arranged in the rotating portion 114, and a clamping space is provided between the second clamping member 12 and the abutting portion 112. The clamping protrusion 310 is located within the clamping space. The first fastener 13 passes through the fixing portion 113, driving the second clamping member 12 to rotate toward the clamping protrusion 310 until the second clamping member 12 clamps the clamping protrusion 310. The pressure block 2 is mounted on top of the base 111 and connected to the base 111 via the second fastener 3. A receiving groove 201 is defined between the pressure block 2 and the base 111, and the photovoltaic module 200 is located within the receiving groove 201. This arrangement securely secures the photovoltaic module 200 to the top of the color-coated steel tile roof 300, reducing maintenance costs.

[0037] Please refer to Figure 1 as well as Figure 4 The color steel tile roof 300 also includes a number of bases 320 arranged in parallel, and the bases 320 protrude from the roof. The clamping protrusion 310 is arranged on the top of the base 320. In this embodiment, the cross-section of the base 320 is trapezoidal to facilitate drainage of the color steel tile roof 300. The clamping protrusion 310 is roughly in the shape of an inverted "L". Specifically, the clamping protrusion 310 includes a first connecting portion 3110 and a second connecting portion 3120, the first connecting portion 3110 is vertically arranged on the top of the base 320, the first connecting portion 3110 is extended in the height direction, and the second connecting portion 3120 is vertically arranged at the free end of the first connecting portion 3110 in the horizontal direction. When the clamping assembly 1 is assembled with the clamping protrusion 310, the abutting portion 112 of the first clamping member 11 is in contact with the first connecting portion 3110, and the free end of the abutting portion 112 abuts against the top of the base 320 to improve the overall structural strength of the first clamping member 11 and the clamping protrusion 310 when they are connected, so that the clamping assembly 1 can be fixedly connected to the clamping protrusion 310.

[0038] Please refer to Figures 2 to 3The second clamping member 12 includes a first clamping portion 121, a second clamping portion 122 perpendicularly disposed to one side of the first clamping portion 121, and a third clamping portion 123 perpendicularly disposed to the other end of the first clamping portion 121. The second clamping portion 122 and the third clamping portion 123 are disposed opposite each other. The free end of the third clamping portion 123 is rotatably disposed on the rotating portion 114. The first fastener 13 passes through the fixed portion 113 and contacts the second clamping portion 122, thereby pushing the second clamping portion 122 to rotate toward the first connecting portion 3110 and tightly adhere to the first connecting portion 3110. This ensures that the first clamping member 11 and the second clamping member 12 are firmly fixed to the clamping protrusion 310.

[0039] The free end of the third clamping portion 123 is provided with a spherical portion 124, and the rotating portion 114 is provided with a groove, and the spherical portion 124 cooperates with the groove. Specifically, the groove is provided with an arcuate surface 1141, and the curvature of the arcuate surface 1141 cooperates with the spherical portion 124, allowing the third clamping portion 123 to rotate more smoothly within the rotating portion 114 and not easily disengage.

[0040] The free end of the second clamping portion 122 is provided with a retaining portion 125, which is positioned toward the side of the fixing portion 113. When the first fastener 13 passes through the fixing portion 113 and contacts the second clamping portion 122, it pushes the second clamping member 12 to rotate. At this time, the end of the first fastener 13 gradually moves toward the retaining portion 125. Therefore, the retaining portion 125 at the free end of the second clamping portion 122 prevents the first fastener 13 from disengaging from the second clamping portion 122, thereby enhancing the secureness of the assembly.

[0041] The fixing portion 113 is provided with a fixing hole 101, and the first fastener 13 is threadedly connected to the fixing hole 101. The assembly is simple and convenient, and the installation cost is reduced.

[0042] Please refer to Figures 2 to 3 The top of the base 111 is provided with two slots 115, which are symmetrically arranged on both sides of the abutment portion 112. The second fastener 3 includes a head 31 and a rod 32 on which the head 31 is provided. The head 31 is fixed in the slot 115, and the rod 32 passes through the pressure block 2 and is connected to the nut 5. Specifically, the slot 115 is recessed downward from the top of the base 111 and includes two first walls 1151 extending vertically downward from the base 111 and a second wall 1152 connecting the same ends of the two first walls 1151. The two first walls 1151 and the second wall 1152 are connected end to end to form the slot 115. The head 31 of the second fastener 3 is fixed in the slot 115 and abuts against the bottom of the base 111, thereby fixing the second fastener 3 in the slot 115. The structure is simple, installation is convenient, and labor costs are reduced.

[0043] Please refer to Figures 2 to 3 as well as Figure 5 In this embodiment, the pressure block 2 has an inverted "J"-shaped structure. The pressure block 2 includes a connecting portion 21 and two pressing portions 22 disposed on opposite sides of the connecting portion 21. Each pressing portion 22 forms two receiving grooves 201 with the base 111, and the two receiving grooves 201 are arranged back to back. The rod portion 32 passes through the connecting portion 21 and is threadedly connected to the nut 5. The connecting portion 21 has a connecting hole, through which the rod portion 32 passes and is threadedly connected to the nut 5, thereby fixedly connecting the pressure block 2 to the first clamping member 11.

[0044] Please refer to Figure 5 The fixed structure 100 also includes two anti-slip blocks 4, each positioned within each receiving slot 201. The anti-slip blocks 4 elastically abut the photovoltaic module 200, the abutting portion 112, and the base 111, respectively. The abutting portion 22 has a serrated portion 221 on the side facing the receiving slot 201, with the anti-slip blocks 4 elastically contacting the serrated portion 221. Specifically, the anti-slip blocks 4 are U-shaped. The anti-slip blocks 4 include a first elastic arm 42 and two second elastic arms 43 perpendicularly disposed at the same end of the first elastic arm 42. One of the second elastic arms 43 elastically abuts the base 111, while the other second elastic arm 43 elastically abuts the serrated portion 221 of the abutting portion 112. The photovoltaic module 200 is inserted between the two geothermal elastic arms. This protects the photovoltaic module 200 during assembly, preventing the fixed structure 100 from scratching the surface of the photovoltaic module 200, which could affect its normal operation. In this embodiment, the anti-slip blocks 4 are made of rubber.

[0045] Please refer to Figure 5 Preferably, the anti-sliding block 4 is provided with a plurality of convex bumps 41 on the side in contact with the photovoltaic module 200, and the convex bumps 41 are in elastic contact with the photovoltaic module 200. Specifically, the plurality of convex bumps 41 are respectively provided on the first elastic arm 42 and the second elastic arm 43, and the convex bumps 41 on the first elastic arm 42 and the second elastic arm 43 are provided correspondingly. In this way, the direct friction between the anti-sliding block 4 and the upper and lower surfaces of the photovoltaic module 200 can be increased. In an embodiment, the shape of the convex bumps 41 is hemispherical. In other embodiments, the shape of the convex bumps 41 can also be block-shaped, or other shapes, which are not limited here.

[0046] In summary, the fixing structure 100 of the present invention includes a clamping assembly 1, a pressure plate, and a second fastener 3. The clamping assembly 1 is fixed to the clamping protrusion 310 of the color steel tile roof 300. The pressure plate is fixed to the clamping assembly 1 via the second fastener 3. The pressure plate and the clamping assembly 1 can clamp the photovoltaic module 200, thereby fixing the photovoltaic module 200 to the clamping protrusion 310. The clamping assembly 1 includes a first clamping member 11, a second clamping member 12, and a first fastener 13. The clamping assembly 1 is fixed to the clamping protrusion 310 of the color steel tile roof 300 via the first fastener 13. The first clamping member 11 includes a base 111, an abutting portion 112 disposed in the base 111, and a fixing portion 113 disposed at the edge of the base 111. The abutting portion 112 abuts against the roof to improve the stability between the first clamping member 11 and the clamping protrusion 310. By setting a rotating portion 114 between the abutting portion 112 and the fixing portion 113, one end of the second clamping member 12 is rotatably set in the rotating portion 114, and the first fastener 13 is passed through the fixing portion 113 to abut against the second clamping member 12, and drives the second clamping member 12 to rotate toward the clamping protrusion 310 until the clamping protrusion 310 is clamped, thereby improving the stability of the connection and fixation between the clamping assembly 1 and the color steel tile roof 300.
