Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, specifically to a frame assembly, mounting assembly, and solar cell assembly for a solar cell. Background Technology

[0002] With the development of the photovoltaic industry, competition in power output for solar cell frame modules is becoming increasingly fierce. For the same area, frame modules with higher power output can command better prices. The structure of a solar cell frame module involves encapsulating and laminating the cell strings between a cover plate and a backsheet to form the module body. A frame is then installed around the edge of the module body to improve the overall strength and tensile strength of the solar cell frame module, and to facilitate subsequent transportation, installation, and the installation of supports adaptable to various environments. An excessively wide frame will obstruct the cell strings, reducing the effective light-receiving area of ​​the cells and consequently lowering the power output.

[0003] like Figure 1 As shown, most solar cell frame modules currently use frames with a C-side, typically 30mm wide. Even with the recent emergence of C-less frames, the long C-side often has mounting holes, meaning the C-less frame is only used on the short side of the solar cell frame module, while the long side still uses a C-side. In actual use, the C-side of the frame still significantly obstructs the solar cells, affecting the power generation of the solar cell frame module.

[0004] How to reduce the shading of the solar cells by the frame and avoid the loss of power generation of the solar cell frame module is a technical problem that urgently needs to be solved. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is that the frame in the prior art will block the battery cells over a large area, which will seriously affect the power generation of the frame module of the solar cell. Thus, this utility model provides a frame module, mounting module and solar cell module for a solar cell.

[0006] To achieve the above objectives, this utility model provides a frame assembly for a solar cell, which includes a plurality of frames connected in sequence.

[0007] The mounting groove is formed by multiple of the aforementioned frames; the mounting groove has an opening through which the edge of the photovoltaic panel is inserted into the mounting groove.

[0008] A cavity is formed by a plurality of the aforementioned frame edges; the cavity is arranged side by side with the mounting slot.

[0009] The frame is provided with a locking part or a protrusion.

[0010] Optionally, the protrusions are provided on the upper and lower sides of the outer side of the frame.

[0011] Optionally, the protrusion is located at the junction of the mounting groove and the cavity, and the extension direction of the protrusion is the same as the extension direction of the cavity.

[0012] Optionally, an overflow groove is formed on the frame, and the overflow groove is at least opposite to the center area of ​​the mounting groove.

[0013] Optionally, the cross-sectional shape of the overflow groove is approximately parabolic.

[0017] The engaging portion is provided on the frame, and the protrusion is provided on the mounting bracket;

[0018] Alternatively, a locking portion provided on the mounting bracket, and a protrusion provided on the frame;

[0019] The protrusion engages with the engaging portion, and the engaging portion is located at the opening of the receiving groove.

[0020] Optionally, the engaging portion is a protrusion provided on the groove wall of the receiving groove and extending in a direction perpendicular to the groove wall.

[0022] A pad, adapted to be movably installed into the receiving groove and extending from the opening of the receiving groove into the receiving groove.

[0025] Compared with the prior art, the technical solution of this utility model has the following advantages:

[0026] 1. This utility model provides a frame assembly for a solar cell. By eliminating the C-shaped border on all frames, the frame assembly not only achieves a C-face-free design, avoiding shading of the solar cells by the C-face and increasing the module's power output, but also offers convenient and quick installation with the mounting bracket. Furthermore, it can accommodate various installation methods such as tilted, vertical, and horizontal installations, making it widely applicable.

[0037] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0040] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0041] like Figure 1 As shown, most solar cell frame modules currently use frames with a C-side, typically 30mm wide. Even with the recent emergence of C-less frames, the long C-side often has mounting holes, meaning the C-less frame is only used on the short side of the solar cell frame module, while the long side still uses a C-side. In actual use, the C-side of the frame still significantly obstructs the solar cells, affecting the power generation of the solar cell frame module.

[0042] How to reduce the shading of the solar cells by the frame and avoid the loss of power generation of the solar cell frame module is a technical problem that urgently needs to be solved.

[0043] Example 1

[0044] like Figures 2 to 6As shown, this embodiment of the present invention provides a frame assembly for a solar cell, which includes a photovoltaic panel and a frame.

[0045] Specifically, in this embodiment of the invention, the frame is composed of multiple sequentially connected frame edges, for example, four sequentially connected frame edges, or more specifically, two long frame edges and two short frame edges. The frame is adapted to mount the photovoltaic panel, and mounting grooves 1 and cavities 2 are formed in the multiple frame edges. The frame is provided with engaging portions 52 or protrusions 3.

[0046] The solar cell frame assembly in this embodiment of the invention eliminates the C-shaped frame on all frames, thus achieving a C-less surface on all frames, avoiding the shading of the solar cells by the C-shaped surface, and increasing the power of the assembly.

[0047] Furthermore, the cavity 2 is arranged side-by-side with the mounting groove 1. The mounting groove 1 has an opening. When installing the photovoltaic panel into the frame, the edge of the laminate in the photovoltaic panel can be inserted into the opening of the mounting groove 1, and then the laminate can be pushed towards the opening to insert it into the mounting groove 1. Also, this frame does not have a C-side. Meanwhile, the cavity 2 is located on the opposite side of the mounting groove 1 from the opening, and the extending direction of the cavity 2 is the same as the extending direction of the mounting groove 1. This arrangement, compared to placing the cavity 2 at the bottom of the mounting groove 1, helps to reduce the height of the frame and facilitates frame transportation.

[0048] Furthermore, such as Figure 2 and Figure 3 As shown, the protrusions 3 can be set on the upper and lower sides of the outer side of the frame, that is, the protrusions 3 are set on the top and bottom of the frame respectively.

[0049] Furthermore, in an optional embodiment of this utility model, such as Figure 2 As shown, the protrusion 3 is located at the junction of the mounting groove 1 and the cavity 2, and the extension direction of the protrusion 3 is the same as the extension direction of the cavity 2.

[0050] Furthermore, in an optional embodiment of this utility model, an overflow groove 4 is provided within the mounting groove 1, the overflow groove 4 is connected to the mounting groove 1, and the overflow groove 4 is at least opposite to the central region of the mounting groove 1. The cross-sectional shape of the overflow groove 4 is approximately parabolic. Of course, this embodiment is merely an example illustrating the structural type of the overflow groove 4, but it is not intended to limit it. Those skilled in the art can determine it according to actual circumstances, as long as the same technical effect is achieved.

[0051] Example 2

[0052] This utility model embodiment also provides a solar cell mounting assembly, which includes the solar cell frame assembly described in any of the above embodiments, and a mounting bracket 5.

[0053] Specifically, the mounting bracket 5 is matched and connected to the frame, and the mounting bracket is also provided with a receiving groove 51 suitable for accommodating the frame. Installation with this mounting bracket 5 is convenient and quick, and it can meet different installation methods such as inclined installation, vertical installation, and horizontal installation, making it widely applicable.

[0054] Furthermore, in an optional embodiment of this utility model, the mounting bracket 5 is connected to the frame via a detachable structure. Specifically, the detachable structure may include a locking portion 52 disposed on the frame and a protrusion 3 disposed on the mounting bracket 5; or, the mounting bracket 52 and the protrusion 3 disposed on the frame.

[0055] Meanwhile, the protrusion 3 cooperates with the engaging part 52, and the engaging part 52 is disposed in the groove of the receiving groove 51.

[0056] Furthermore, in an optional embodiment of this utility model, the mounting bracket 5 is further provided with a receiving groove 51 suitable for accommodating the frame, and the engaging part 52 is disposed at the opening of the receiving groove 51. When installing the frame, the protrusion 3 of the frame can be directly embedded into the receiving groove 51 of the mounting bracket 5, and the engaging part 52 can directly abut against the protrusion 3 to prevent the frame from detaching from the mounting bracket 5.

[0057] Furthermore, in an optional embodiment of this utility model, the engaging part 52 is a protrusion provided on the groove wall of the receiving groove 51 and extending in a direction perpendicular to the groove wall.

[0058] Furthermore, in an optional embodiment of this invention, the frame assembly of the solar cell further includes a pad 6 adapted to be movably mounted into the receiving groove 51. When mounting frame assemblies of multiple solar cells, the pad 6 can be extended from the opening of the receiving groove 51 into the receiving groove 51.

[0059] When installing frame assemblies for multiple solar cells, if you don't want the frame of the first solar cell to touch the bottom directly, you can first extend the spacer 6 along the groove 51 of the mounting bracket 5 to the bottom, and then install the first spacer 6. After the frame of the first solar cell is installed, extend the spacer 6 along the groove 51 of the mounting bracket 5 above the first solar cell frame assembly. Afterwards, the remaining solar cell frame assemblies can be installed in the same way as the first solar cell frame assembly. If conditions permit, spacers 6 can be omitted between adjacent solar cell frame assemblies. Of course, multiple spacers 6 can also be installed depending on the actual situation; this is entirely up to the user.

[0060] The solar cell frame assembly in this embodiment of the present invention does not require the use of clamping blocks, bolts or other installation tools during the assembly installation process. Under suitable conditions, even the pad 6 can be omitted. The installation process is also very simple. Just insert the frame of the assembly into the receiving groove 51 of the mounting bracket 5 and then extend it into the receiving groove 51.

[0061] Furthermore, in an optional embodiment of this invention, the pad 6 is detachably connected to the receiving groove 51. This detachable connection allows for more stable installation of the solar cell frame assembly during the installation process.

[0064] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
