[0002] On the current market, the surfaces of the frames of most photovoltaic modules are higher than the surfaces of the laminates. After long-term use, it is easy to cause dust accumulation at the frame position on the front side of the photovoltaic module. After the dust accumulates, it will block the surface of the photovoltaic module, which will not only affect the front power generation efficiency of the photovoltaic module, but also cause hot spot phenomenon, leading to safety hazards such as overheating of the photovoltaic module.

[0003] In order to avoid dust accumulation on the front frame of the photovoltaic module, effectively reduce the shielding of the frame to the front of the photovoltaic module, increase the aesthetics, and at the same time reduce the shielding of the frame to the light-receiving area on the front of the photovoltaic module, the frame design of the photovoltaic module without A side has also been developed on the market.

The partition plate, the glue-blocking plate and the baffle plate enclose a glue storage chamber, and the opening of the glue storage chamber faces away from the bearing plate, wherein the first direction intersects with the second direction.

[0004] Although the glue storage chamber of the existing photovoltaic module frame can play a role in overflowing glue, when the amount of injected glue is too much, the capacity of the glue storage chamber is limited, and it is still possible to cause some glue to overflow and contaminate the surface of the laminate.

Detailed Embodiment

[0025] Next, the present utility model will be described in detail with reference to the drawings. What is described herein is only the preferred embodiment of the present utility model, and those skilled in the art can think of other ways to implement the present utility model based on the preferred embodiment, and such other ways also fall within the scope of the present utility model.

[0026] Embodiment

[0027] Please refer to Figures 1-3 , this embodiment provides a photovoltaic profile, including a bottom plate 110, which is arranged in the first direction. An outer side plate 120, which is connected to the bottom plate 110 and arranged in the second direction. A supporting plate 130, which is connected to the outer side plate 120 and arranged parallel to the bottom plate 110, and the supporting plate 130 is used to support the laminate 200. The first direction intersects with the second direction. Specifically, in this embodiment, the first direction and the second direction are perpendicularly arranged. When the laminate 200 is horizontally installed, the first direction refers to the horizontal direction and the second direction refers to the vertical direction.

[0028] When the laminate 200 of the photovoltaic module and the profile are assembled into a frame, silicone is applied between the laminate 200 and the profile. In order to prevent the silicone from overflowing and contaminating the surface of the laminate 200, in this embodiment, as Figure 1 and Figure 3As shown in the figure, a first glue overflow groove 140 is provided on one side of the top end portion 121 of the outer side plate 120 facing the laminate 200. The top end portion 121 extends beyond the plane where the support plate 130 is located. A second glue overflow groove 142 is provided on one side of the support plate 130 facing the laminate 200. When the laminate 200 is installed on the photovoltaic profile, there is a glue overflow gap 141 between the photovoltaic profile and the laminate 200. The first glue overflow groove 140 and the second glue overflow groove 142 are communicated through the glue overflow gap 141. The glue overflow gap 141 enables the excess glue to flow from the first glue overflow groove 140 into the second glue overflow groove 142, or from the second glue overflow groove 142 into the first glue overflow groove 140. The existence of the glue overflow gap 141 can communicate the first glue overflow groove 140 and the second glue overflow groove 142. Compared with the traditional glue storage chamber of the photovoltaic frame, it is equivalent to expanding the volume of the glue storage chamber, can accommodate more glue, and reduces the risk of glue overflow.

[0029] Specifically, as Figure 1 shown in the figure, a connecting protrusion 143 is formed by the connection between the outer side plate 120 and the support plate 130 protruding towards the laminate 200. The glue overflow gap 141 is provided between the connecting protrusion 143 and the laminate 200. After the laminate 200 is installed, the connecting protrusion 143 can be close to the laminate 200. Through the connection of silicone, the connecting protrusion 143 can play a certain supporting role for the laminate 200 and increase the installation stability of the laminate 200. A support protrusion 131 is provided at the free end of the support plate 130. The support protrusion 131 contacts the bottom surface of the laminate 200; the second glue overflow groove 142 is located between the support protrusion 131 and the connecting protrusion 143. The support protrusion 131 and the connecting protrusion 143 jointly support the laminate 200, which can keep a certain distance between the bottom of the laminate 200 and the position outside the support protrusion 131 of the support plate 130, which is helpful for the flow of silicone during installation, and can also increase the capacity of the second glue overflow groove 142 to further prevent silicone from overflowing. It should be noted that the number of the second glue overflow grooves 142 can be multiple or one. In this embodiment, only one second glue overflow groove 142 is provided, and the edges on both sides of the second glue overflow groove 142 are respectively connected to the support protrusion 131 and the connecting protrusion 143.

[0030] In order to further prevent silicone from overflowing from the top of the profile and contaminating the surface of the laminate 200 during the frame installation of the laminate 200, in this embodiment, as Figure 1 and Figure 3As shown, a glue-blocking stopper 122 protrudes from one side of the top end portion 121 towards the laminate 200. The glue-blocking stopper 122 abuts against the laminate 200, and the top end of the glue-blocking stopper 122 does not extend beyond the surface of the laminate 200. On the one hand, the glue-blocking stopper 122 can prevent the silicone from overflowing from the top end portion 121, reducing the risk of front surface glue overflow, improving the appearance of the component, saving the cleaning cycle of the production line, and increasing the production capacity. On the other hand, since the top end of the glue-blocking stopper 122 does not extend beyond the surface of the laminate 200, a borderless A-surface structure can be formed, and the glue-blocking stopper 122 will not block the light-receiving surface of the laminate 200, which is beneficial to improving the photoelectric conversion efficiency of the photovoltaic module. In addition, when the photovoltaic module is installed obliquely, the glue-blocking stopper 122 will not block the edge of the laminate 200, and rainwater can self-clean the surface of the photovoltaic module without water accumulation or dust accumulation.

[0031] In this embodiment, as Figure 1 shown, an inner side plate 150 is connected between the support plate 130 and the bottom plate 110. The inner side plate 150, the support plate 130, the bottom plate 110, and the outer side plate 120 enclose a cavity 160, and the inner side plate 150 is parallel to the outer side plate 120. The cavity 160 facilitates the connection of multiple profiles to form a carrier for loading the laminate 200. A reinforcing plate 170 is disposed in the cavity 160. Two sides of the reinforcing plate 170 are respectively connected to the bottom plate 110 and the support plate 130, and the reinforcing plate 170 is parallel to the outer side plate 120. The reinforcing plate 170 can optimize and enhance the overall bearing capacity of the frame, enhance the bearing capacity of the front surface bearing frame of the component to a certain extent, reduce deformation, and better stabilize the frame during outdoor operation. Further, reinforcing ribs are respectively provided on one side of the bottom plate 110, the support plate 130, the inner side plate 150, and the reinforcing plate 170 located in the cavity 160 to further improve the bearing capacity of the profile. The connection between the bottom plate 110 and the outer side plate 120 has a smooth transition, and the connection between the bottom plate 110 and the outer side plate 120 is rounded, making the connection part integrally arc-shaped.

[0032] The present application also provides a photovoltaic frame, including a plurality of the above-mentioned photovoltaic profiles. The plurality of profiles are connected to form a loading space for loading the laminate 200, and the loading space is integrally rectangular.

[0033] On the other hand, the present application also provides a photovoltaic module, including the above-mentioned photovoltaic frame and the laminate 200, and the laminate 200 is installed in the loading space.
