DETAILED DESCRIPTION

[0027] In order to make the above objectives, features and advantages of the present application more clear and easily understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of different ways beyond the specific embodiments described and claimed in this disclosure and it is therefore intended that the present application not be limited to the described embodiments.

[0028] As the background art, in the prior art, in the long-term outdoor use, under the action of the self-weight of the photovoltaic module and the high-frequency vibration of external force, the compression between the mounting plate of the photovoltaic frame and the mounting fitting is loose, and then the photovoltaic module falls off from the photovoltaic support. The inventor found that the reason for this problem is that the transverse mechanical properties of the photovoltaic frame made of glass fiber reinforced resin composite material are weaker than those of the photovoltaic frame made of aluminum alloy material due to the process characteristics of the photovoltaic frame made of glass fiber reinforced resin composite material. Therefore, in the case of being installed and fixed on the photovoltaic support by using fasteners such as bolts, there is a certain risk of failure. Even if the mounting fitting is added between the fastener and the photovoltaic frame to reinforce the transverse mechanical properties, under the action of the self-weight of the module and the high-frequency vibration of external force in the long-term outdoor use, the compression between the photovoltaic frame and the mounting fitting is still loose, and then the photovoltaic module falls off from the photovoltaic support.

[0029] It should be noted that the transverse direction of the photovoltaic frame in the present embodiment refers to the extension direction of the photovoltaic frame, such as the direction indicated by the arrow S in Figure 2 .

[0030] Based on the above reasons, the present application provides a photovoltaic frame, a photovoltaic module and a photovoltaic ceiling, which can effectively prevent the photovoltaic module from falling off from the photovoltaic support and improve the installation stability.

[0031] Referring to Figure 1 and Figure 2 , Figure 1 , a structure diagram of the photovoltaic module of an embodiment of the present application installed on the photovoltaic support 30 is shown. Figure 2A perspective view of the frame body 11 of the photovoltaic frame 10 is shown.

In this way, the first assembly portion 121 can be stably arranged inside the positioning groove 1171, thereby improving the mounting stability of the mounting fitting 12 and effectively preventing the photovoltaic module from sliding off the photovoltaic support 30, and improving the installation reliability in long-term outdoor use.

[0036] On the basis of the foregoing embodiment, when the first assembly portion 121 is arranged inside the positioning groove 1171, the opposite sides of the first assembly portion 121 are simultaneously in abutting positioning with the limiting flange 1172 and the connecting plate 115, so that the outer periphery of the first assembly portion 121 is respectively in abutting positioning with the inner wall of the positioning groove 1171, and the first assembly portion 121 is stably arranged inside the positioning groove 1171.

It should be noted that the anti-disengagement part 117 in the present embodiment is designed synchronously in the forming mold of the frame body 11 and is the same as the frame body 11 as a whole, and is completed by injection molding in the pultrusion forming process, that is, the anti-disengagement part 117 is integrated with the frame body 11. After the anti-disengagement part 117 is formed by the pultrusion process, the positioning groove 1171 is further processed on the anti-disengagement part 117. Optionally, the positioning groove 1171 is formed on the anti-disengagement part 117 by punching, shearing, milling or laser etching, or can be directly formed by mold processing, which can be flexibly adjusted and set according to actual needs, and is not limited herein.

[0042] When the frame body 11 is made of a glass fiber reinforced resin composite material, a protective coating can be optionally added to the surface of the frame body 11, and the protective coating is baked to provide better weather resistance and richer colors for the photovoltaic frame 10.

[0043] Of course, as some optional solutions, the anti-disengagement part 117 can also be two independent structures with the frame body 11, and can be connected and fixed together by various ways such as bonding or welding.

[0044] In one embodiment, the positioning grooves 1171 are a plurality of and are sequentially and spacedly arranged in the transverse direction. The mounting fittings 12 are one or more, the number of the mounting fittings 12 is less than or equal to the number of the positioning grooves 1171, and one mounting fitting 12 is arranged in one positioning groove 1171. In addition, the fasteners 13 are one or more, and each fastener 13 is arranged corresponding to each mounting fitting 12. In this way, when the positioning grooves 1171, the mounting fittings 12 and the fasteners 13 are a plurality of, the frame body 11 can be fixed on the photovoltaic support 30 at a plurality of different positions in the transverse direction, so as to be stably arranged on the photovoltaic support 30 and effectively prevent the photovoltaic module from sliding off the photovoltaic support 30. In addition, when the number of the positioning grooves 1171 is more than the number of the mounting fittings 12, appropriate positioning grooves 1171 can be selected to arrange the mounting fittings 12 in the assembly process, which has high flexibility.

[0045] In some embodiments, the fasteners 13 include but are not limited to bolts, screws, pins, rivets or clamping pieces, and the like, which can be flexibly adjusted and set according to actual needs, as long as the second assembly part 122 can be fixed and arranged on the photovoltaic support 30.
