[0029] See Figure 1 、 Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of a photovoltaic color steel tile fixing structure provided in one embodiment of the utility model. Figure 2 This is a front view of the photovoltaic color steel tile fixing structure provided in one embodiment of the utility model. Figure 3A front view of a photovoltaic color steel tile fixing structure supporting color steel tiles provided in one embodiment of the present invention. The photovoltaic color steel tile fixing structure provided in one embodiment of the present invention includes a main body 100, which is used to be connected to a mounting surface. The main body 100 is provided with a groove 110 and a support surface 120. The groove 110 is used to plug and cooperate with the protrusion 210 on the color steel tile 200. The support surface 120 is located to the side of the notch of the groove 110 to support the color steel tile 200. The groove 110 has a protrusion 170 on the side wall. The protrusion 170 is used to snap-fit with the snap-fit groove 220 on the color steel tile 200 to prevent the color steel tile 200 from falling out of the groove 110.

[0030] Specifically, in the present application, the main body 100 is fixed to the mounting surface, and the notch of the groove 110 is facing upward. The support surface 120 on the side of the notch of the groove 110 abuts against the color steel tile 200 to support the color steel tile 200. The groove 110 is plugged into and matched with the protrusion 210 on the color steel tile 200 to limit the installation position of the color steel tile 200. The protrusion 170 on the side wall of the groove 110 engages with the engaging groove 220 of the color steel tile 200 to limit the movement of the color steel tile 200 in the direction of gravity, thereby improving the wind resistance of the color steel tile 200. In this embodiment, the mounting surface is located on the purlin. In other embodiments, the mounting surface can also be located on other supporting structures.

[0031] It should be noted that the color steel tile 200 has a protrusion 210 protruding toward the side of the installation surface, and a snap-in groove 220 is provided on the side wall of the protrusion 210. When the protrusion 210 is inserted into the groove 110, the snap-in groove 220 can be snap-fitted with the protrusion 170 on the side wall of the groove 110, thereby limiting the protrusion 210 from escaping from the groove 110 along the direction of gravity.

[0032] See Figure 1 and Figure 2 In one embodiment, the bottom wall of the groove 110 abuts against the protrusion 210 of the color steel tile 200, thereby increasing the support area of the photovoltaic color steel tile fixing structure for the color steel tile 200 and improving the stability of the support for the color steel tile 200.

[0033] See Figure 1 and Figure 3 In one embodiment, there are two supporting surfaces 120 , and the groove 110 is disposed between the two supporting surfaces 120 . In the direction in which the protrusion 210 is inserted into the groove 110 , the distance between the two supporting surfaces 120 gradually expands.

[0034] Specifically, the two support surfaces 120 are symmetrically arranged and inclined relative to the horizontal plane. When the protrusion 210 on the color steel tile 200 is inserted into the groove 110, the support surfaces 120 on both sides of the groove 110 respectively abut against the color steel tile 200, thereby providing stable support force on both sides of the color steel tile 200. At the same time, it can also provide the color steel tile 200 with opposite forces along the arrangement direction of the two support surfaces 120, thereby stably restricting the movement of the color steel tile 200 along the arrangement direction of the two support surfaces 120, and improving the stability of the color steel tile 200 installed in the photovoltaic color steel tile fixing structure.

[0035] See Figure 1-Figure 3 In one embodiment, the main body 100 includes a support plate 130 and two spaced apart mating plates 140, one end of each mating plate 140 is used to connect to the mounting surface, and the other end is used to connect to the support plate 130 to support the support plate 130, and the support plate 130 is partially recessed toward one side of the mating plate 140 to form a groove 110, and the support surface 120 is located on the support plate 130.

[0036] Specifically, the mating plate 140 is located below the support plate 130, with the support plate 130 partially recessed, forming the groove 110. The two mating plates 140 are connected to the mounting surface at one end and to the support plate 130 at the other end, thereby stabilizing the support plate 130 and improving the stability of the photovoltaic color steel tile fixing structure. The main body 100, composed of the support plate 130 and the mating plate 140, saves material and makes the photovoltaic color steel tile fixing structure lightweight.

[0037] See Figure 1 、 Figure 2 and Figure 3 In one embodiment, the support plate 130 includes a first portion 131, a second portion 132 and a third portion 133. The first portion 131 is connected to the mating plate 140, and the supporting surface 120 is located on the first portion 131. The third portion 133 is surrounded by the groove wall of the groove 110. One end of the second portion 132 is connected to the first portion 131, and the other end is connected to the third portion 133. The second portion 132 is arranged at an angle to the first portion 131 and the third portion 133. The second portion 132 is used to abut against the color steel tile 200.

[0038] Specifically, compared to the method in which the first portion 131 is directly connected to the second portion 132, in the present application, one end of the second portion 132 is connected to the first portion 131 and the other end is connected to the third portion 133. The second portion 132 is arranged at an angle to the first portion 131 and the third portion 133, which can reduce the bending degree of the support plate 130 and reduce damage to the support plate 130. Among them, the second portion 132 abuts against the color steel tile 200, thereby ensuring a larger supporting surface 120 area for the color steel tile 200 while avoiding stress concentration and reducing damage to the color steel tile 200.

[0039] Furthermore, a matching surface 150 connected to the supporting surface 120 is provided on the second portion 132 . The matching surface 150 is used to abut against the color steel tile 200 , and the plane where the matching surface 150 is located is perpendicular to the direction of gravity.

[0040] See Figure 1 and Figure 3 In one embodiment, a relief opening 111 is provided on the wall of the groove 110. Specifically, the relief opening 111 is provided on the third portion 133, which can achieve a lightweight configuration and reserve space for a connection structure on the color steel tile 200 to connect with the photovoltaic module.

[0041] See Figure 1 and Figure 3 In one embodiment, the mating plate 140 includes a first section 141 and a second section 142, the first section 141 is used to connect to the mounting surface, the second section 142 is connected to the first section 141 at one end close to the groove 110, and the second section 142 is connected to the support plate 130 at one end away from the groove 110.

[0042] Specifically, the end of the support plate 130 away from the groove 110 extends beyond the first section 141, thereby increasing the support area of the support plate and improving the stability of the photovoltaic color steel tile fixing structure supporting the color steel tile 200. Preferably, the first section 141 extends along the direction of gravity.

[0043] See Figure 1 and Figure 3 In one embodiment, the second section 142 is fitted with the support plate 130 , that is, the second section 142 overlaps with the support plate 130 , thereby enhancing the stability of the entire high photovoltaic color steel tile fixing structure and the supporting strength of the support plate 130 .

[0044] Furthermore, the mating plate 140 further includes a third section 143. The end of the third section 143 near the groove 110 is connected to the second section 142, and the third section 143 is bent relative to the second section 142. The photovoltaic color steel tile fixing structure further includes a fastener 160. The fastener 160 is disposed through the third section 143 and connected to the mounting surface to secure the mating plate 140 to the mounting surface. Preferably, the fastener 160 is a screw.

[0045] The third section 143 is perpendicular to the second section 142 , extends in a horizontal direction, and is used to fit with the mounting surface, thereby improving the stability of the connection between the main body 100 and the mounting surface.

[0046] See Figure 1 、 Figure 2 and Figure 3 In one embodiment, the end of the protrusion 170 is bent toward one side of the bottom wall of the groove 110, thereby having a guiding effect, facilitating the insertion of the protrusion 210 on the color steel tile 200 into the groove 110, and improving the convenience of installing the color steel tile 200 and the photovoltaic color steel tile fixing structure.

[0047] Furthermore, the protrusion 170 is connected to the edge portion of the avoidance opening 111, and in the direction of gravity, the projection of the protrusion 170 falls into the avoidance opening 111, so that when the protrusion 210 of the color steel tile 200 is inserted into the groove 110 of the main body 100, the protrusion 210 applies a downward thrust to the protrusion 170, and the protrusion 170 can be easily deformed to bend toward the side of the avoidance opening 111, thereby facilitating the convenient insertion of the protrusion 210 into the groove 110.

[0048] See Figure 1 、 Figure 2 and Figure 3 In one embodiment, the protrusion 170 is arc-shaped, so that the protrusion 210 on the color steel tile 200 is inserted into the groove 110, reducing damage to the color steel tile 200.

[0049] The present invention also provides a photovoltaic system, including a photovoltaic module, a color steel tile 200, and the above-mentioned photovoltaic color steel tile fixing structure, wherein the photovoltaic color steel tile fixing structure is used to fix the color steel tile 200, and the color steel tile 200 is used to support the photovoltaic module. In the present application, the main body 100 is fixed to the installation surface, and the notch of the groove 110 is directed upward. The supporting surface 120 on the side of the notch of the groove 110 abuts against the color steel tile 200 to achieve support for the color steel tile 200. The groove 110 is plugged into and matched with the protrusion 210 on the color steel tile 200 to limit the installation position of the color steel tile 200. The protrusion 170 on the side wall of the groove 110 is engaged with the snap-fit groove 220 of the color steel tile 200 to limit the movement of the color steel tile 200 in the direction of gravity, thereby improving the wind resistance of the color steel tile 200 and further improving the stability of the photovoltaic module.

[0050] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
