DETAILED DESCRIPTION

[0026] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0027] Combine the following Figure 1-Figure 7 A clamp according to an embodiment of the first aspect of the present application is described.

[0028] Figure 1 FIG. 2 shows a schematic diagram of a three-dimensional structure of a clamp according to an embodiment of the present application. Figure 1 As shown, the clamp 10 includes a first connecting member 100 and a second connecting member 200 .

[0029] Specifically, the first connector 100 includes a photovoltaic connection plate 110, a first connection plate 120 and a first clamping plate 130. The photovoltaic connection plate 110 is used to connect photovoltaic modules and extends horizontally. The first connection plate 120 is used to overlap the roof lock edge structure and is connected between the photovoltaic connection plate 110 and the first clamping plate 130, and the first clamping plate 130 is perpendicular to the photovoltaic connection plate 110. The second connector 200 includes a second connection plate 210 and a second clamping plate 220 connected to each other. The second connection plate 210 is parallel to the photovoltaic connection plate 110, and the second connection plate 210 is connected to the first connection plate 120 by fasteners, and the second clamping plate 220 is arranged opposite to the first clamping plate 130, so that the roof lock edge structure is clamped between the second clamping plate 220 and the first clamping plate 130.

[0030] Exemplarily, the surfaces of the photovoltaic connecting plate 110 and the second connecting plate 210 are parallel to the horizontal plane; the surfaces of the first clamping plate 130 and the second clamping plate 220 are perpendicular to the horizontal plane. The first connecting plate 120 can be formed in an "L" shape. A first mounting hole 123 can be formed on the first connecting plate 120, and a second mounting hole 211 can be formed on the second connecting plate 210. The fastener can be passed through the first connecting plate 120 and the second connecting plate 210 through the first mounting hole 123 and the second mounting hole 211, so as to achieve a fixed connection between the entire first connector 100 and the second connector 200. Optionally, the fastener can be a threaded fastener, such as a stainless steel bolt, to avoid rust while ensuring a secure connection between the first connector 100 and the second connector 200. The central axis of the fastener is perpendicular to the photovoltaic connecting plate 110.

[0031] For example, the first connector 100 may be an integral structure, and the photovoltaic connection plate 110, the first connection plate 120 and the first clamping plate 130 may be formed by bending. The second connector 200 may be an integral structure, and the second connection plate 210 and the second clamping plate 220 may be formed by bending.

[0032] According to the clamp 10 of the embodiment of the present application, the photovoltaic connection plate 110 can be connected to the photovoltaic module, and the first clamping plate 130 and the second clamping plate 220 can clamp the roof lock structure, so that the photovoltaic module can be installed on the roof module. Moreover, by connecting the second connection plate 210 to the first connection plate 120 through fasteners, a secure connection between the first connection member 100 and the second connection member 200 can be achieved, so that the installation stability of the photovoltaic module can be effectively guaranteed, thereby improving safety and long-term reliability. In addition, the structure of the clamp 10 is simple and the cost is low.

[0033] Figure 2 Show Figure 1 A front view of the fixture 10 shown in ; Figure 3 Show Figure 1In one embodiment, referring to Figure 1-Figure 3 The second connecting member 200 may further include a support plate 230, one end of the support plate 230 (eg, Figure 2 and Figure 3 The lower end of the support plate 230 is connected to the edge of the second connecting plate 210 away from the second clamping plate 220, and the other end of the support plate 230 (for example, Figure 2 and Figure 3 The upper end of the first connecting plate 120 is in contact with the first connecting plate 120. Figure 1-Figure 3 In the example, the surface of the support plate 230 may be perpendicular to the horizontal plane. When the fastener is a threaded fastener such as a stainless steel bolt, during the assembly process of the first connecting plate 120 and the second connecting plate 210, the force between the support plate 230 and the first connecting plate 120 gradually increases during the process of gradually tightening the threaded fastener. Here, "abutment" can be understood as the other end of the support plate 230 is in contact with the first connecting plate 120 and there is a force.

[0034] In this embodiment, by providing the support plate 230 abutting against the first connecting plate 120, the connection between the first connecting member 100 and the second connecting member 200 is made more stable and reliable, thereby further ensuring the installation stability of the photovoltaic module.

[0035] In one embodiment, a limiting groove may be provided at the bottom of the first connecting plate 120, and the other end of the supporting plate 230 is matched and connected to the limiting groove, and the other end of the supporting plate 230 abuts against the inner wall of the limiting groove. Figure 1-Figure 3 During installation, when the first mounting hole 123 is formed on the first connecting plate 120 and the second mounting hole 211 is formed on the second connecting plate 210, the other end of the support plate 230 can be firstly matched in the limiting groove, thereby limiting the relative movement of the first connecting plate 120 and the second connecting plate 210 in the left-right direction, so that the first mounting hole 123 and the second mounting hole 211 can be aligned up and down. Then, the fastener is passed through the first mounting hole 123 and the second mounting hole 211 and is provided in the first connecting plate 120 and the second connecting plate 210, so as to realize the fixed connection of the entire first connecting member 100 and the second connecting member 200.

[0036] In this embodiment, by making the other end of the support plate 230 cooperate with the limit groove, the relative movement between the support plate 230 and the first connecting plate 120 can be limited, while improving the assembly efficiency of the entire clamp 10 and ensuring the stability and long-term reliability of the clamp 10 during use.

[0037] In one embodiment, the two surfaces of the second connecting plate 210 in the thickness direction are respectively the first surface and the second surface, the first surface is arranged opposite to the first connecting plate 120, the support plate 230 is located on the first surface, and the second clamping plate 220 is located on the second surface. In this way, the support plate 230 and the second clamping plate 220 can be located on both sides of the second connecting plate 210 in the thickness direction, respectively, and the second clamping plate 220 does not need to occupy the space of the first surface, so that a larger accommodation space can be defined between the support plate 230, the first surface of the second connecting plate 210 and the first connecting plate 120, and at least part of the roof lock edge structure can be located in the accommodation space, and the layout is more reasonable.

[0038] Figure 4 Show Figure 1 A left side view of the clamp 10 shown in FIG. Figure 5 Show Figure 1 In one embodiment, the clamp 10 is shown in the right side view. Figure 1 , Figure 4 and Figure 5 The first connecting plate 120 includes a horizontal plate 121 and a vertical plate 122. The horizontal plate 121 is parallel to the photovoltaic connecting plate 110 and connected between the vertical plate 122 and the first clamping plate 130. The horizontal plate 121 overlaps the roof lock edge structure. The vertical plate 122 is perpendicular to the photovoltaic connecting plate 110 and connected between the horizontal plate 121 and the photovoltaic connecting plate 110. The fasteners are connected to the horizontal plate 121 and the second connecting plate 210. For example, in Figure 2 In the example, the photovoltaic connecting plate 110 and the vertical plate 122 together form a "7" shape; the vertical plate 122 and the horizontal plate 121 together form an "L" shape; the horizontal plate 121 and the first clamping plate 130 together form a "7" shape.

[0039] Therefore, by making the first connecting plate 120 include a horizontal plate 121 and a vertical plate 122, on the one hand, the vertical plate 122 can improve the structural strength of the first connecting member 100 and prevent the horizontal dimension of the first connecting member 100 from being too large and thus bending and warping; on the other hand, the setting of the vertical plate 122 can make the photovoltaic connecting plate 110 higher than the roof locking structure, thereby increasing the installation space of the photovoltaic module.

[0040] In one embodiment, the roof edge locking structure may include a first part and a second part arranged vertically, the thickness of the first part is greater than the thickness of the second part, and the first part is located above the second part, and the second part is clamped between the first clamping plate 130 and the second clamping plate 220 (not shown). For example, the orthographic projection of the first part on the horizontal plane may be located within the orthographic projection of the second connecting member 200 on the horizontal plane. In this way, the first part can have a certain limiting effect on the second clamping plate 220 to prevent the fixture 10 from detaching from the roof edge locking structure.

[0041] Figure 6 Show Figure 1 A top view of the fixture 10 shown in FIG. Figure 7 Show Figure 1 A bottom view of the fixture 10 shown in FIG. Figure 1 , Figure 6 and Figure 7 As shown, the photovoltaic connection plate 110 is provided with an elongated hole 111 for connecting the photovoltaic module, and the elongated hole 111 penetrates the photovoltaic connection plate 110 along the thickness direction of the photovoltaic connection plate 110. For example, the photovoltaic module can be connected to the photovoltaic connection plate 110 through a photovoltaic bracket. The setting of the photovoltaic bracket enables the clamp 10 to adapt to photovoltaic modules of different shapes and sizes. The setting of the elongated hole 111 allows the operator to properly adjust the photovoltaic bracket, thereby playing a role in adjusting the photovoltaic module. Among them, the elongated hole 111 can extend along the arrangement direction of the first clamping plate 130 and the second clamping plate 220.

[0042] In this embodiment, the stress of the photovoltaic module can be released by providing the elongated holes 111, thereby ensuring the quality and reliability of the photovoltaic module. In addition, the clamping force and position of the photovoltaic module can be adjusted through the elongated holes 111, thereby ensuring the installation flatness of the photovoltaic module and avoiding errors.

[0043] In one embodiment, the first connector 100 and the second connector 200 may both be aluminum alloy parts. Therefore, since aluminum alloy is a lightweight material, the weight of the clamp 10 is small and easy to install. In addition, the clamp 10 may have high corrosion resistance and high strength, and is not easily oxidized and corroded, thereby extending the service life of the clamp 10.

[0044] The second aspect of the present application provides a roof system, including a roof assembly (not shown), a photovoltaic assembly (not shown) and a clamp 10 of any of the above embodiments. Among them, the roof assembly includes a roof locking structure. The photovoltaic connecting plate 110 of the clamp 10 is connected to the photovoltaic assembly, the first connecting plate 120 of the clamp 10 is overlapped on the roof locking structure, and the roof locking structure is clamped between the second clamping plate 220 and the first clamping plate 130 of the clamp 10. Exemplarily, the roof assembly can be a 360-degree bite locking roof assembly. The photovoltaic assembly can be a double-glass photovoltaic assembly to improve the solar energy conversion efficiency.

[0045] According to the roof system of the embodiment of the present application, the photovoltaic module can be installed on the roof module by using the above-mentioned clamp 10. Moreover, the installation stability of the photovoltaic module can be effectively guaranteed, thereby improving safety and long-term reliability.
