Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, specifically to a frame, frame, and photovoltaic module that provides better fixing effect for photovoltaic laminates. Background Technology

[0002] Photovoltaic arrays are used in outdoor environments. When installed outdoors, the installation angle of photovoltaic array components is generally based on the slope (for example, in industrial and commercial distributed projects, the angle of corrugated steel roof is relatively small, with a tilt angle of generally 3 to 12°). Usually, a lot of dust will accumulate on the glass surface at the bottom edge of the component. Since the A side of the frame of traditional photovoltaic array components is higher than the top glass surface of the photovoltaic laminate, rainwater mixed with dust will be retained on the top surface of the glass surface, and the smaller the tilt angle of the photovoltaic component, the more water will be retained.

[0003] To avoid dust accumulation on the glass surface, a frameless A-side structure is used in related technologies. However, due to the lack of frame support for the top surface of the glass, the fixing effect on the photovoltaic laminate is poor. Utility Model Content

To this end, this application provides a frame, a frame, and a photovoltaic module, which improves the stability of fixing the photovoltaic laminate for structures without an A-side frame.

[0011] Furthermore, the laminate bearing portion includes a bearing plate and a limiting plate, the bearing plate and the limiting plate together defining the receiving notch, the bearing surface is formed on the bearing plate, the limiting surface is formed on the limiting plate, the frame body is disposed on the side of the bearing plate opposite to the bearing surface or on the side of the limiting plate opposite to the limiting surface, and a corner code cavity is formed on the frame body for connecting with a corner code connector.

[0027] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this application and should not be construed as limiting it.

[0028] The terms "an embodiment," "example," or "example" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this application. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0029] The first aspect of this application discloses a border, see appendix. Figure 1 and Figure 2The frame includes a frame body 10 and a laminate support portion 20. The laminate support portion 20 is located on one side of the frame body 10, and a receiving notch 23 is formed on the laminate support portion 20. The receiving notch 23 includes a support surface 211 and a limiting surface 221. The limiting surface 221 is used to face the side wall of the photovoltaic laminate 30. The support surface 211 is used to support the bottom surface of the photovoltaic laminate 30. The top of the limiting surface 221 is not higher than the top surface of the photovoltaic laminate 30. The width of the support surface 211 is greater than the height of the limiting surface 221.

[0030] In this embodiment, the frame is used in conjunction with other frames. Multiple frames are generally arranged to form a square frame, which is set on the outside of the photovoltaic laminate 30 to support and protect the photovoltaic laminate 30.

[0031] In this embodiment, the frame structure supports the photovoltaic laminate 30 through the laminate support part 20. The laminate support part 20 includes a support plate 21 and a limiting plate 22. The support plate 21 and the limiting plate 22 together define the receiving notch 23. The support surface 211 is formed on the support plate 21, and the limiting surface 221 is formed on the limiting plate 22. When the photovoltaic laminate 30 is installed, the bottom surface of the photovoltaic laminate 30 is supported by the support surface 211, and the top surface of the photovoltaic laminate 30 is higher than the top surface of the limiting surface 221, forming a frameless structure without side A as shown in the figure. In this way, dust or water on the top surface of the photovoltaic laminate 30 can be discharged from the limiting surface 221 of the frame, avoiding the accumulation of dust on the surface of the photovoltaic laminate 30.

[0032] In this embodiment, the limiting surface 221 is disposed on the outside of the photovoltaic laminate 30. During the installation process, the limiting surface 221 plays a role in limiting the photovoltaic laminate 30. Together with the bearing surface 211 and the adhesive disposed between the photovoltaic laminate 30, the bearing surface 211 and the limiting surface 221, the photovoltaic laminate 30 is stably fixed on the frame.

[0033] In the related technology, the bearing width of the bearing surface 211 and the height of the limiting surface 221 are basically the same. When the frame has an A-side structure, the A-side structure will press on the top surface of the photovoltaic laminate 30, which provides support for the upper and lower surfaces of the photovoltaic laminate 30, and the fixing effect of the photovoltaic laminate 30 is good.

[0034] However, in this embodiment, the frame is a mechanism without side A. In this embodiment, the width of the bearing surface 211 is greater than the height of the limiting surface 221, which can increase the bearing area of ​​the bottom surface of the photovoltaic laminate 30 and improve the stability of the photovoltaic laminate 30.

[0035] This embodiment does not specifically limit the relationship between the width of the bearing surface 211 and the height of the limiting surface 221. In actual settings, please refer to Appendix 1 and 2. The ratio of the width H1 of the bearing surface 211 to the height H2 of the limiting surface 221 can be set between 1.5 and 3.

[0036] As one embodiment of this utility model, see the appendix. Figure 1 , 2 The limiting surface is opposite to the side wall of the photovoltaic laminate 30. A glue storage groove 222 is formed on the limiting surface 221 of the limiting plate 22. The bottom surface of the glue storage groove 222 is connected to the bearing surface 211. The bearing surface 211 is provided with a glue retention groove 212.

[0037] In this embodiment, both the limiting surface 221 of the limiting plate 22 and the bearing surface 211 of the bearing plate 21 are provided with adhesive grooves. In this way, during the installation of the photovoltaic laminate 30, the presence of adhesive grooves will leave more adhesive in the corresponding parts, thereby improving the fixing effect on the bottom and sides of the photovoltaic laminate 30.

[0038] In this embodiment, the specific depth, shape, and number of the glue storage tank 222 and the glue retention tank 212 are not specifically limited. For actual installation, please refer to the appendix. Figure 1 The depth of the adhesive storage tank 222 is greater than that of the adhesive retention tank 212, so that the side of the photovoltaic laminate 30 can have a better bonding effect with the limiting surface 221, thereby improving the stable connection of the photovoltaic laminate 30.

[0039] In this embodiment, the bottom surface of the glue storage tank 222 is connected to the bearing surface 211. In actual installation, when adhesive is injected between the photovoltaic laminate 30 and the frame, the adhesive in the glue storage tank 222 and the top surface of the bearing surface 211 will be interconnected. That is, the glue storage tank 222 can provide an overflow hole for the adhesive on the bearing surface 211. Moreover, the interconnected structure of the adhesive can also make the bonding part continuous when it is bonded to the photovoltaic laminate 30, which can improve the fixing effect of the photovoltaic laminate 30.

[0040] As one embodiment of this utility model, see the appendix. Figure 1 , 2 The limiting surface 221 of the limiting plate 22 is provided with a glue-blocking platform 223, which is located on the top side of the glue storage tank 222, and one end of the glue-blocking platform 223 extends into the glue storage tank 222.

[0041] In this embodiment, a baffle platform 223 is provided on the limiting surface 221. The baffle platform 223 can block the top side of the glue storage tank 222 to prevent the glue in the glue storage tank 222 from overflowing from the top side of the limiting surface 221, thereby preventing the glue from overflowing to the top surface of the photovoltaic laminate 30.

[0042] In one embodiment of the present invention, the top opening edge of the glue storage tank 222 extends into the glue storage tank 222 and forms the glue-blocking platform 223, the two ends of the glue-blocking platform 223 being flush with the two ends of the glue storage tank 222.

[0043] In this embodiment, the length of the glue-blocking platform 223 and the length of the glue storage tank 222 are consistent, so that the glue in the glue storage tank 222 can be prevented from overflowing from the top side in the entire length direction of the frame.

[0044] In this embodiment, the length of the adhesive blocking platform 223 extending into the adhesive storage tank 222 is not specifically limited, as long as it can prevent the adhesive liquid 40 in the adhesive storage tank 222 from overflowing. Generally, the length of the adhesive blocking platform 223 can be set between 0.5mm and 1.5mm.

[0045] As one embodiment of this utility model, see the appendix. Figure 1 The bearing surface 211 is provided with a plurality of adhesive retention grooves 212, which are spaced apart along the width direction of the bearing surface 211.

[0046] In this embodiment, the arrangement of multiple adhesive grooves 212 allows for a stable bonding effect on the bottom surface of the photovoltaic laminate 30 at different locations on a relatively wide bearing surface. The specific number of adhesive grooves 212 is not specified in this embodiment; as shown in the attached figure… Figure 1 As shown, in one embodiment of this application, the bearing surface 211 is provided with three adhesive retention grooves 212. The cross-sectional shape of the adhesive retention grooves 212 in this embodiment can be set as trapezoidal, W-shaped, V-shaped, etc.

[0047] In one embodiment of the present invention, the frame body 10 is disposed on the side opposite to the bearing plate 21 and the bearing surface 211 or on the side opposite to the limiting plate 22 and the limiting surface 221. An angle code cavity 11 is formed on the frame body 10, and the angle code cavity 11 is used to connect with the angle code connector 50.

[0048] The second aspect of this application discloses a frame for a photovoltaic module, the frame comprising a plurality of frame edges connected end to end, at least one of the plurality of frame edges being the frame edge described in the first aspect.

[0049] In this embodiment, the four borders of the frame can be one, two, three, or four, adopting the border structure of the first aspect.

[0050] When the frame has only one frame using the first aspect, that is, when the photovoltaic module has only one side without an A-side structure, this side without an A-side frame can be set at a relatively low position during the on-site installation of the photovoltaic module. In this way, impurities on the surface of the photovoltaic laminate 30 will be removed from the photovoltaic laminate 30 under the action of gravity.

[0051] When all four borders in the frame adopt the border structure of the first aspect, the assembly process of the frame and photovoltaic laminate 30 in this embodiment is different from the assembly process of photovoltaic modules with A-side borders in related technologies.

[0052] Specifically, firstly, the four borders are connected together using corner bracket connectors 50 to form a complete frame. See attached diagram. Figure 4 Then, with the front side of the frame (the top side of the load-bearing part) facing upwards, use a glue applicator to apply glue along the laminated load-bearing part of the frame, see attached... Figure 5 After the glue is applied, as shown below Figure 6 , 7 As shown, the frame with the adhesive applied is flipped over so that the adhesive side faces down, and then transported above the photovoltaic laminate 30 and pressed down. As the frame and the laminate are pressed against each other, the adhesive will deform, and excess adhesive will enter the adhesive storage tank 222. (See attached diagram.) Figure 3 As shown in the figure, it can be seen that the frame and photovoltaic laminate 30 in this embodiment can be assembled as a whole, which improves assembly efficiency.

[0053] As one embodiment of this utility model, see the appendix. Figure 4 The frame also includes a corner code connector 50. Each of the plurality of borders is provided with a corner code cavity 11. Two adjacent borders are connected by the corner code connector 50. The corner code connector 50 includes two connecting parts, which are respectively inserted into the corner code cavity 11 corresponding to two adjacent borders.

[0054] A third aspect of this application discloses a photovoltaic module, see appendix. Figure 3 The photovoltaic module includes a photovoltaic laminate 30 and a frame, which is disposed on the side of the photovoltaic laminate 30.

[0055] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Those skilled in the art should understand that this application includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this application will be included within the scope of the claims.
