[0002] In a photovoltaic module, the frame is an important load-bearing component of the photovoltaic panel, and its role is particularly important. "The frame to the module" is similar to "the skeleton to the human body", and the mechanical strength of the photovoltaic module frame measures the mechanical strength of the module. In addition, during the installation of a power station, the frame plays a fixing role. From this perspective, the significance of the frame is great.

[0003] For example, Chinese patent document with publication number CN117914244A discloses a frame unit, a photovoltaic module frame and a curved screen photovoltaic module. The frame unit includes: a first connecting portion; a second connecting portion, which is perpendicularly arranged with respect to the first connecting portion.

The end of the limiting wall is not higher than the laminate; a supporting portion, which is fixedly installed on the second connecting portion. The first connecting portion and the supporting portion are arranged on the same surface of the second connecting portion, and the supporting portion is adapted to support and cooperate with the back surface of the laminate.

[0004] The limiting wall in the above patent document adopts an arc surface design, and its first arc surface is tightly pressed and cooperates with the front surface of the laminate. When cleaning the photovoltaic module, the water flow with dust flows downward along the photovoltaic module. To a certain extent, the water flow will not be blocked by the limiting wall. However, there will still be gaps between the arc surface of the limiting wall and the laminate even when they are tightly pressed, and the water flow will flow into the space between the limiting wall and the laminate, affecting the timely discharge of the water flow and possibly causing water accumulation inside the frame. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the present utility model will be described in detail with reference to the drawings. What is described here is only the preferred embodiment of the present utility model. Those skilled in the art can think of other ways to implement the present utility model based on the preferred embodiment, and other ways also fall within the scope of the present utility model.

[0027] Embodiment

[0028] Please refer to Figures 1 - 4 , this embodiment provides a frame for a curved photovoltaic module, including a first side support frame 120 and a top support frame 140. The first side support frame 120 and the top support frame 140 are perpendicularly arranged and both are used to support the curved glass 200; the connection part between the first side support frame 120 and the top support frame 140 shrinks inward to form a recessed part. The shrinkage of the recessed part will create more space, making it easier for the curved glass 200 to be positioned and installed with the frame. The curved surface of the curved glass 200 covers the recessed part, and the curved surface of the curved glass 200 completely blocks the recessed part, and at the same time also blocks the gap at the connection between the curved glass 200 and the frame. When water flows down along the curved surface, it will not enter the gap, avoiding water from entering between the curved glass 200 and the frame and reducing the drainage difficulty. The end of the first side support frame 120 abuts against the curved end of the curved glass 200, making the first side support frame 120 smoothly connect with the curved surface of the curved glass 200. When water flows down along the curved surface of the curved glass 200, it will not be blocked, which helps the water to be discharged in time and avoids the accumulation of water on the surface of the curved glass 200.

[0029] Specifically, in this embodiment, as Figure 1 and Figure 2 shown, the recessed part includes a transverse connecting rod 150, a longitudinal connecting rod 151 and an arc connecting rod 152. The transverse connecting rod 150 is connected to the inner side of the first side support frame 120, the longitudinal connecting rod 151 is perpendicular to and connected to the transverse connecting rod 150, and the arc connecting rod 152 connects the longitudinal connecting rod 151 with the top support frame 140. The perpendicular connection between the longitudinal connecting rod 151 and the transverse connecting rod 150 can increase the space for the recessed part to shrink inward, and at the same time, their perpendicular arrangement can also increase the structural strength of the recessed part. The arc connecting rod 152 makes the transition between the recessed part and the top support frame 140 smooth. The arc radian of the arc connecting rod 152 is the same as the curved radian of the curved glass 200, which can make the arc connecting rod 152 and the curved surface of the curved glass 200 form a parallel arc structure and reduce the space between the curved surface and the arc connecting rod 152.

[0030] Furthermore, in this embodiment, please refer to Figure 1 and Figure 2 , a first protrusion 153 is arranged on the side of the longitudinal connecting rod 151 facing the curved glass 200. The first protrusion 153 and the end of the first side support frame 120 form a gap groove 154, and an adhesive is filled in the gap groove 154. The adhesive is used to bond the curved glass 200 and the frame. The first protrusion 153 and the end of the first side support frame 120 jointly provide support for the curved surface of the curved glass 200 in two directions, increasing the installation stability of the curved glass 200 and the frame. In this embodiment, the adhesive mainly used is silicone. Silicone has high bonding strength, high temperature resistance, ultraviolet resistance, and good thermal stability, which is suitable for the solar light environment faced by photovoltaic modules.

[0031] In this embodiment, please continue to refer to Figure 1 , on the side of the top support frame 140 facing the curved glass 200, a plurality of second protrusions 155 are provided. The plurality of second protrusions 155 are arranged at intervals and are in contact with the inner side of the curved glass 200. The multiple second protrusions 155 can provide multiple support points for the curved glass 200, improving the structural stiffness of the curved glass 200. Moreover, the second protrusions 155 arranged at intervals can prevent the curved glass 200 from directly contacting the frame, creating channels between the second protrusions 155, which is convenient for draining water in extreme rain and snow weather.

[0032] In this embodiment, as Figure 1 shown, the component frame further includes a bottom support frame 110 and a second side support frame 130. The bottom support frame 110 is vertically arranged and connected to the first side support frame 120, and the second side support frame 130 connects the bottom support frame 110 and the second side support frame 130; the bottom support frame 110, the first side support frame 120, the yielding part, the top support frame 140, and the second side support frame 130 enclose a cavity 160. On the one hand, the cavity 160 can reduce the overall weight of the frame, and on the other hand, it can facilitate the assembly of multiple frames.

[0033] Furthermore, a plurality of reinforcing ribs 121 are provided on the inner side of the first side support frame 120, and the reinforcing ribs 121 extend towards the inner side of the cavity 160. The reinforcing ribs 121 can enhance the structural strength of the frame, reduce the risk of frame deformation, and at the same time improve the supporting force for the curved glass 200. The connection between the bottom support frame 110 and the first side support frame 120 is smoothly connected through an arc section 122. The arc section 122 can increase the smoothness of the outer side of the frame, reduce the sharpness and sharpness of the frame, lower the risk of the frame being bumped, and avoid damaging the components during transportation.

[0034] On the other hand, the present application provides a photovoltaic module, including a curved glass 200 and a plurality of photovoltaic module frames. The frame bodies 100 of two photovoltaic module frames are arranged opposite to each other, and the curved surfaces on the opposite sides of the curved glass 200 respectively cover the yielding parts of the two frame bodies 100. Without replacing the aluminum alloy base material, the gap grooves 154 at the yielding parts are closely matched with the curved glass 200, making the frame and the curved glass 200 integrated, improving the aesthetics; the yielding parts of the frame body 100 enable the surface of the module to have a smooth transition, thereby improving the sewage discharge, drainage, and snow discharge capabilities, and at the same time avoiding unnecessary gaps. The frame bodies 100 are connected through corner codes 300, and the corner codes 300 are installed in the cavity 160. The cooperation between the corner codes 300 and the cavity 160 of the frame body 100 is convenient and compact.
