Description

Technical Field

[0001] The utility model relates to the field of photovoltaic production, and more specifically, to a photovoltaic component frame. Background Art

[0002] Photovoltaic modules are part of a solar power generation system. Individual solar cells cannot be used directly as a power source. To function as such, they must be connected in series and parallel and tightly packaged into modules. Solar cell modules are the core and most important component of a solar power generation system. Since photovoltaic panels cannot be used alone, they require a sturdy, aesthetically pleasing, and practical frame and glass assembly.

[0003] For example, in the Chinese patent document with publication number CN105703701B, the disclosed technical solution forms mounting grooves for photovoltaic panels between the vertical frame, top frame, and upper frame of the cavity. The photovoltaic panels are fixed by the vertical frame, top frame, and upper frame. Each frame is in direct contact with the photovoltaic panel. However, because the frame and glass are both relatively hard, while the glass is relatively weak, direct contact between the two can easily cause the module glass to break during installation and use. Therefore, a photovoltaic module frame is urgently needed that can prevent damage caused by the frame colliding with the photovoltaic panel. Utility Model Content

[0004] The utility model provides a photovoltaic component frame, which solves the problem in the prior art that the frame and the photovoltaic panel are relatively hard and in direct contact, which easily causes the component glass to break during installation and use.

[0005] In order to achieve the above-mentioned purpose, the technical solution provided by the present utility model is:

[0006] A photovoltaic module frame includes a bottom frame and a frame surrounding the circumference of the bottom frame to form a cavity for mounting a glass module at an opening. A connecting frame is also provided on the inner side of the bottom frame, and a supporting frame connected to the frame is provided above the connecting frame to form a mold cavity in the cavity. The supporting frame is provided with a first overflow glue groove for accommodating silicone on the side close to the frame, and a boss for supporting the glass module on the side away from the frame. A first glue strip mounting groove is provided on the boss, and a first glue strip is provided in the first glue strip mounting groove to adhere to the bottom of the supporting glass module. The portion of the frame that exceeds the height of the supporting frame forms a side support portion, and a second glue strip mounting groove is provided on the inner side of the side support portion, and a second glue strip is provided in the second glue strip mounting groove to adhere to the side of the supporting glass module.

[0007] Furthermore, the side support portion is inclined toward the glass assembly from the root formed at the connection between the support frame and the frame, the inner side of the end portion presses and fixes the side of the glass assembly, and the highest point of the top is not higher than the top plane of the glass assembly.

[0008] Furthermore, the second adhesive strip has a different cross-sectional shape from the first adhesive strip. Preferably, the first adhesive strip has a circular cross-sectional shape, with its arc-shaped side surface contacting the bottom surface of the glass assembly. Preferably, the second adhesive strip has a rectangular cross-sectional shape, with its rectangular side surface contacting the sidewall of the glass assembly.

[0009] Furthermore, the first rubber strip installation groove includes two opposite side portions, and the side portion close to the boss is higher than the other side portion.

[0010] Preferably, a second glue overflow groove is provided on the inner side of the side support portion around the second glue strip installation groove. Preferably, the first glue overflow groove includes a plurality of groove bodies arranged in sequence along the length direction of the support frame.

[0015] (2) The photovoltaic module frame of the present invention can better and more stably support the glass module by setting the inclined side support part. The highest point of the top is lower than the top plane of the glass module, or is flush with the top plane of the glass module, which can also enhance the integrity of the structure and avoid dust accumulation at the contact point between the frame and the glass module.

[0016] (3) The utility model provides a photovoltaic module frame, wherein the support frame and the side support portion are respectively provided with a first rubber strip and a second rubber strip having different cross sections.

[0020] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, this embodiment provides a photovoltaic module frame, including a bottom frame 1 and a frame 2 surrounding the bottom frame 1 to form a cavity 3 for mounting a glass assembly 4 at the opening. A connecting frame 5 is also provided on the inner side of the bottom frame 1, and a support frame 6 connected to the frame 2 is provided above the connecting frame 5 to form a cavity 17 in the cavity 3. The connecting frame 5 and the bottom frame 1 can be provided in an integral molding manner or connected by a fixed connection method such as screw connection. Similarly, the bottom frame 1 and the frame 2, the frame 2 and the support frame 6, and the support frame 6 and the connecting frame 5 can be connected in a similar manner. In addition, in a possible embodiment, the bottom frame 1, the frame 2, the connecting frame 5, and the support frame 6 can all be made of aluminum alloy or polyurethane composite material or steel structure material with an anodized surface.

[0022] When transporting the assembly, the conventional assembly frame structure is in direct contact with the glass assembly 4, and the two are prone to squeezing or collision, which may cause the glass assembly 4 to break. For this reason, in this embodiment, a rubber strip is provided between the glass assembly 4 and the frame to act as a buffer. Specifically, the support frame 6 is provided with a first overflow glue groove 7 for accommodating silicone on the side close to the frame 2, and a boss 8 for supporting the glass assembly 4 is provided on the side away from the short frame 2. The boss 8 is provided with a first rubber strip mounting groove 9, and a first rubber strip 10 is provided in the first rubber strip mounting groove 9 to adhere to and support the bottom of the glass assembly 4. The portion of the frame 2 that exceeds the height of the support frame 6 forms a side support portion 11, and a second rubber strip mounting groove 12 is provided inside the side support portion 11. The second rubber strip mounting groove 12 is provided with a second rubber strip 13 to adhere to and support the side of the glass assembly 4. Specifically, the second rubber strip 13 and the first rubber strip 10 have different cross-sectional shapes. Specifically, the first rubber strip 10 has a circular cross-section, with its arc-shaped side contacting the bottom surface of the glass assembly 4; the second rubber strip 13 has a rectangular cross-section, with its rectangular side contacting the sidewall of the glass assembly 4. The elasticity of the first and second rubber strips 10, 13 creates effective prestressed support between the support frame 6, the side support portion 11, and the glass assembly 4, preventing breakage during assembly handling and installation, thereby reducing the risk of component breakage during construction and installation.

[0023] In this embodiment, by providing the first adhesive strip 10 and the second adhesive strip 13, when the glass assembly 4 is supported by the frame structure composed of the bottom frame 1 and the frame 2, the bottom frame 1, the frame 2 and the glass assembly 4 can play a role in buffering, isolating, and slowing down the collision between the frame structure and the glass assembly 4 when the bottom frame 1, the frame 2 and the glass assembly 4 are in direct contact or collision, thereby effectively preventing the glass assembly 4 from being broken due to collision.

[0024] In one possible embodiment, the side support portion 11 is inclined from the root formed at the connection between the support frame 6 and the frame 2 toward the glass assembly 4, with the inner side of its end pressing and fixing the side surface of the glass assembly 4, and the highest point of its top is no higher than the top plane of the glass assembly 4. Specifically, the highest point of the top of the side support portion 11 can be lower than the top plane of the glass assembly 4, or flush with the top plane of the glass assembly 4, thereby avoiding dead angles. This can enhance the overall stability of the structure and prevent dust accumulation at the contact point between the frame 2 and the glass assembly 4.

[0025] In a possible embodiment, the first rubber strip installation groove 9 includes two opposite side portions, and the side portion close to the boss 8 is higher than the other side portion.

[0026] Furthermore, a first glue overflow groove 7 is provided on one side of the support frame 6 near the lower side. Specifically, the first glue overflow groove 7 comprises a plurality of grooves arranged in sequence along the length of the support frame 6. In one possible embodiment, an arcuate transition groove 14 is provided on the inner side of the connection between the support frame 6 and the frame 2, which can also be used to drain glue.

[0027] In another possible embodiment, a second glue overflow groove 18 is provided on the inner side of the side support portion 11 around the second glue strip installation groove 12. Specifically, the second glue strip installation groove 12 is formed by a convex portion located on the inner side surface of the side support portion 11, and a groove structure with a glue overflow function is formed between the convex portion and the inner side surface of the side support portion 11.

[0028] Furthermore, the junction of the bottom frame 1 and the frame 2 has an arc-shaped connecting portion 15 for easy transportation, and the inner side of the frame 2 has a reinforcing rib 16 arranged in the cavity 17 to enhance the stability of the overall structure.
