Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module manufacturing technology, and in particular relates to a photovoltaic module frame. Background Technology

[0002] To improve the ease of installation and transportation of photovoltaic modules, a frame structure is usually set around the photovoltaic modules, and the photovoltaic modules are embedded in the receiving groove of the frame structure.

[0003] The existing frame structure's receiving groove has an anti-overflow adhesive structure along its upper edge. This anti-overflow adhesive structure forms a sealed space with the front of the photovoltaic module, storing the silicone in the receiving groove and preventing the front of the photovoltaic module from being affected by overflow adhesive. However, the design of the receiving groove without an anti-overflow adhesive structure at its lower edge means that, due to the size difference of the photovoltaic modules, if there is an excessively large assembly gap between the photovoltaic module and the frame structure during the assembly process, the silicone storage function of the anti-overflow adhesive structure will fail, resulting in overflow adhesive on the front of the photovoltaic module and affecting the effect of light on the photovoltaic module. Utility Model Content

[0004] The purpose of this utility model is to solve the aforementioned technical problems by providing a photovoltaic module frame. This frame allows the photovoltaic module to be positioned within the receiving groove via a support structure, preventing gaps between the photovoltaic module and the anti-overflow adhesive structure. The anti-overflow adhesive structure effectively stores the adhesive, ensuring no adhesive overflow on the surface of the photovoltaic module. To achieve the above objective, the technical solution of this utility model is as follows:

[0005] A photovoltaic module frame includes a frame structure and an anti-overflow adhesive structure. The frame structure and the anti-overflow adhesive structure are connected to form a receiving groove. The bottom of the receiving groove faces the edge of the photovoltaic module. A support structure is provided in the receiving groove on the opposite side of the anti-overflow adhesive structure. The anti-overflow adhesive structure and the support structure limit the photovoltaic module. The surface of the photovoltaic module abuts against the anti-overflow adhesive structure to form a sealed space. The bottom surface of the photovoltaic module abuts against the support structure. An overflow adhesive space is formed between the support structure and the frame structure. The sealed space communicates with the overflow adhesive space and is filled with adhesive.

[0006] Specifically, the support structure includes a support frame and a plurality of support legs disposed at the ends of the support frame; the end of the support frame away from the support legs abuts against the bottom of the receiving groove, and the support legs abut against the wall of the receiving groove.

[0007] Specifically, the support frame is provided with a plurality of first overflow ports arranged at intervals, and a second overflow port is provided between adjacent support legs. The second overflow port faces the opening of the receiving groove, and the first overflow port and the second overflow port are connected.

[0008] Specifically, one end of the first overflow port is located inside the support frame, and the other end of the first overflow port is located at the edge of the support frame and communicates with the outside.

[0009] Specifically, the frame structure includes a frame base plate, frame side plates disposed on the frame base plate, and a fixing frame disposed between the frame base plate and the frame side plates;

[0010] The fixing frame includes a first fixing part and a second fixing part connected together. The end of the first fixing part is connected to the side of the frame side plate, and the end of the second fixing part is connected to the top of the frame bottom plate. The first fixing part is parallel to the frame bottom plate in the horizontal direction, and the second fixing part is parallel to the frame side plate in the vertical direction.

[0011] Specifically, the frame structure also includes a fixing plate that connects to the top of the frame side plate and extends vertically;

[0012] The anti-overflow adhesive structure is disposed on the side of the fixing plate, and the anti-overflow adhesive structure, the fixing plate and the first fixing part are sequentially connected to form a receiving groove, and the support structure is disposed on the top of the first fixing part.

[0013] Specifically, the anti-overflow adhesive structure includes an anti-overflow adhesive body and a cover plate disposed on the anti-overflow adhesive body;

[0014] One end of the cover plate is connected to the side of the frame side plate, and the other end of the cover plate extends to the end that covers the anti-overflow adhesive body. One end of the anti-overflow adhesive body is connected to the side of the frame side plate, and the other end of the anti-overflow adhesive body is pressed against the surface of the photovoltaic module.

[0015] Specifically, a connecting part is provided on one side of the bottom of the anti-overflow adhesive body, and an elastic part is provided on the other side of the bottom of the anti-overflow adhesive body. The elastic part is spaced apart from the end of the anti-overflow adhesive body, and an adhesive storage tank for storing adhesive is formed between the connecting part and the elastic part. The end of the elastic part has an inner buckle edge, and the inner buckle edge is pressed against the surface of the photovoltaic module.

[0016] Specifically, the bottom of the connecting part is spaced apart from the surface of the photovoltaic module, and the side of the connecting part is provided with an inner groove, which is arranged opposite to the inner edge.

[0017] Specifically, the bottom of the anti-overflow adhesive body is provided with a plurality of barrier blocks located in the adhesive storage tank and spaced apart. The barrier blocks are spaced apart from the connecting part and the elastic part, and the bottom of the barrier blocks are pressed against the surface of the photovoltaic module.

[0018] Compared with existing technologies, the beneficial effects of this utility model's photovoltaic module frame are mainly reflected in:

[0019] A receiving groove is formed by connecting the frame structure and the anti-overflow adhesive structure. The bottom of the receiving groove faces the edge of the photovoltaic module, allowing the photovoltaic module to be installed along the groove opening. The anti-overflow adhesive structure rests against the surface of the photovoltaic module. The sealed space formed by the anti-overflow adhesive structure and the photovoltaic module can store and block the adhesive. The adhesive is then discharged from the overflow space formed by the support structure and the frame structure. The support structure in the receiving groove serves two purposes: firstly, it provides an overflow space, allowing the adhesive to overflow from the support structure, reducing the amount of adhesive that overflows into the sealed space and lowering the probability of anti-overflow adhesive structure failure; secondly, it supports the photovoltaic module. Replacing the support structure in the receiving groove can accommodate the positioning of photovoltaic modules with different sizes, ensuring that the photovoltaic module is accurately positioned between the support structure and the anti-overflow adhesive structure. This ensures the stability of the sealed space formed between the photovoltaic module surface and the anti-overflow adhesive structure, preventing excessive gaps between the photovoltaic module and the anti-overflow adhesive structure, which would affect the adhesive storage function of the sealed space and thus prevent the adhesive from overflowing from the anti-overflow adhesive structure onto the surface of the photovoltaic module.

[0030] Photovoltaic module 5. Detailed Implementation

[0031] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0032] Example 1

[0033] This embodiment provides a photovoltaic module frame, such as Figures 1-5 As shown, the device includes a frame structure 1 and an anti-overflow adhesive structure 2. The frame structure 1 and the anti-overflow adhesive structure 2 are connected to form a receiving groove 3. The bottom of the receiving groove 3 is set towards the edge of the photovoltaic module 5. A support structure 4 is set in the receiving groove 3 on the opposite side of the anti-overflow adhesive structure 2. The anti-overflow adhesive structure 2 and the support structure 4 limit the photovoltaic module 5. The surface of the photovoltaic module 5 abuts against the anti-overflow adhesive structure 2 to form a sealed space 31 for storing adhesive. The bottom surface of the photovoltaic module 5 abuts against the support structure 4. An overflow adhesive space 32 is formed between the support structure 4 and the frame structure 1. The sealed space 31 and the overflow adhesive space 32 are connected and filled with adhesive.

[0034] In this embodiment, the surface of the photovoltaic module 5 is its front side, and the bottom surface of the photovoltaic module 5 is its back side.

[0035] The support structure 4 includes a support frame 41 and a plurality of support legs 42 disposed at the end of the support frame 41; the end of the support frame 41 away from the support legs 42 abuts against the bottom of the receiving groove 3, and the support legs 42 abut against the wall of the receiving groove 3.

[0036] In this embodiment, two support feet 42 extend downward from the ends of the support frame 41, and the support feet 42 are perpendicular to the support frame 41. The support structure 4 has several overflow ports, allowing the adhesive in the receiving groove 3 to be discharged from the overflow ports.

[0037] The support frame 41 is provided with a plurality of first overflow ports 43, which are arranged at equal intervals along the same direction of the support frame 41; a second overflow port 44 is provided between adjacent support legs 42, the second overflow port 44 is located at the end of the support structure 4, the second overflow port 44 faces the opening of the receiving groove 3, and the first overflow port 43 is connected to the second overflow port 44; at the same time, one end of the first overflow port 43 is located inside the support frame 41, and the other end of the first overflow port 43 is located at the edge of the support frame 41 and connected to the outside, and the first overflow port 43 is an open design.

[0038] When the end of the support frame 41 abuts against the bottom of the receiving groove 3, during the process of inserting the photovoltaic module 5 into the receiving groove 3, the adhesive in the receiving groove 3 is squeezed out by the photovoltaic module 5 and overflows to the anti-overflow adhesive structure 2. The sealed space 31 formed by the anti-overflow adhesive structure 2 and the surface of the photovoltaic module 5 effectively blocks the overflow of adhesive. The adhesive in the receiving groove 3 can enter the first overflow port 43 from the bottom of the groove and be discharged from the second overflow port 44. The adhesive overflows out of the receiving groove 3 along the overflow space 32. The support structure 4 achieves a fast and uniform overflow effect, and the support foot 42 of the support structure 4 separates the photovoltaic module 5 from the adhesive, reducing the amount of adhesive overflowing to the bottom surface of the photovoltaic module 5.

[0039] In this embodiment, a receiving groove 3 is formed by connecting the frame structure 1 and the anti-overflow adhesive structure 2. The bottom of the receiving groove 3 faces the edge of the photovoltaic module 5, allowing the photovoltaic module 5 to be installed along the opening of the receiving groove 3. The anti-overflow adhesive structure 2 abuts against the surface of the photovoltaic module 5. The sealed space 31 formed by the anti-overflow adhesive structure 2 and the photovoltaic module 5 can store and block the adhesive. Then, the adhesive is discharged from the overflow space 32 formed by the support structure 4 and the frame structure 1. The support structure 4 in the receiving groove 3 serves to provide the overflow space 32, allowing the adhesive to overflow from the support structure 4 and reducing the amount of adhesive entering. The overflow of the sealed space 31 reduces the probability of failure of the anti-overflow adhesive structure 2; on the other hand, it supports the photovoltaic module 5. Replacing the support structure 4 in the receiving groove 3 can be used to position photovoltaic modules 5 with different sizes, so that the photovoltaic module 5 can be accurately positioned between the support structure 4 and the anti-overflow adhesive structure 2, ensuring the stability of the sealed space 31 formed by the surface of the photovoltaic module 5 and the anti-overflow adhesive structure 2, avoiding the gap between the photovoltaic module 5 and the anti-overflow adhesive structure 2 being too large, which would affect the adhesive storage function of the sealed space 31, and thus prevent the adhesive from overflowing from the anti-overflow adhesive structure 2 to the surface of the photovoltaic module 5.

[0040] Example 2

[0041] This embodiment optimizes the photovoltaic module frame based on the above embodiments, and in particular provides a specific implementation of the frame structure:

[0042] like Figure 1 , Figure 2 As shown, the frame structure 1 includes a frame base plate 11, frame side plates 12 disposed on the frame base plate 11, and a fixing frame 13 disposed between the frame base plate 11 and the frame side plates 12.

[0043] In this embodiment, both the frame base plate 11 and the frame side plate 12 are plate structures. The bottom of the frame side plate 12 is connected to the end of the frame base plate 11, and the frame side plate 12 is perpendicular to the frame base plate 11.

[0044] In this embodiment, the fixing frame 13 has an L-shaped structure. One end of the fixing frame 13 is connected to the side of the frame side plate 12, and the other end is connected to the top of the frame bottom plate 11. Specifically, the fixing frame 13 includes a first fixing part 131 and a second fixing part 132 connected to each other. The first fixing part 131 and the second fixing part 132 are perpendicular to each other. The end of the first fixing part 131 is connected to the side of the frame side plate 12, and the end of the second fixing part 132 is connected to the top of the frame bottom plate 11. The first fixing part 131 is relatively parallel to the frame bottom plate 11 in the horizontal direction, and the second fixing part 132 is relatively parallel to the frame side plate 12 in the vertical direction. The fixing frame 13 stably supports the frame bottom plate 11 and the frame side plate 12, and strengthens the connection strength between the frame bottom plate 11 and the frame side plate 12.

[0045] The frame structure 1 also includes a fixing plate 14 that connects to the top of the frame side plate 12 and extends vertically. An anti-overflow adhesive structure 2 is disposed on the side of the fixing plate 14, and the fixing plate 14 is perpendicular to the first fixing part 131. The anti-overflow adhesive structure 2, the fixing plate 14, and the first fixing part 131 are sequentially connected to form a receiving groove 3. The anti-overflow adhesive structure 2 and the first fixing part 131 are located on the same side of the fixing plate 14. In this embodiment, the receiving groove 3 is a roughly U-shaped structure, the fixing plate 14 is the bottom of the receiving groove 3, and the first fixing part 131 and the anti-overflow adhesive structure 2 are the walls of the receiving groove 3. A support structure 4 is provided on the top of the first fixing part 131. The horizontal distance of the support structure 4 is less than the horizontal distance of the first fixing part 131, so that the support structure 4 can be completely placed in the receiving groove 3, which facilitates the placement of the support structure 4 in the receiving groove 3.

[0046] Example 3

[0047] This embodiment optimizes the photovoltaic module frame based on the above embodiments, and in particular provides a specific implementation of an anti-overflow adhesive structure:

[0048] like Figure 1 , Figure 5 As shown, the anti-overflow adhesive structure 2 includes an anti-overflow adhesive body 21 and a cover plate 22 disposed on the anti-overflow adhesive body 21; one end of the cover plate 22 is connected to the side of the frame side plate 12, and the other end of the cover plate 22 extends to the end that covers the anti-overflow adhesive body 21. The end of the cover plate 22 covering the anti-overflow adhesive body 21 has an arc-shaped structure.

[0049] A connecting portion 23 is provided on one side of the bottom of the anti-overflow adhesive body 21, and an elastic portion 24 is provided on the other side of the bottom of the anti-overflow adhesive body 21. The elastic portion 24 is spaced apart from the end of the anti-overflow adhesive body 21, and an adhesive storage tank 25 for storing adhesive is formed between the connecting portion 23 and the elastic portion 24. In this embodiment, the anti-overflow adhesive body 21 is made of an elastic material and has certain deformation characteristics. The end of the elastic portion 24 has an inner buckle 241, which is pressed against the surface of the photovoltaic module 5.

[0050] When the photovoltaic module 5 is inserted into the receiving groove 3, the surface of the photovoltaic module 5 contacts the inner edge 241. The inner edge 241 is deformed and rolled inward by friction. The inner edge 241 can effectively block the colloid and prevent the colloid from overflowing out of the inner edge 241.

[0051] One end of the anti-overflow adhesive body 21 is connected to the side of the frame side plate 12, and the other end of the anti-overflow adhesive body 21 is pressed against the surface of the photovoltaic module 5. When the inner buckle 241 fails to prevent overflow adhesive, the end of the anti-overflow adhesive body 21 can further prevent overflow adhesive. The elastic part 24 and the end of the anti-overflow adhesive body 21 can store adhesive.

[0052] The bottom of the connecting part 23 is spaced apart from the surface of the photovoltaic module 5, allowing the colloid to enter the colloid storage tank 25 from the receiving groove 3 through the bottom of the connecting part 23. The side of the connecting part 23 is provided with an inner groove 231 relative to the inner edge 241, which makes it easier for the colloid to remain in the colloid storage tank 25, thereby enhancing the ability of the colloid storage tank 25 to stably store colloid.

[0053] The bottom of the anti-overflow adhesive body 21 is provided with a number of barrier blocks 26 located in the adhesive storage tank 25 and spaced apart. The barrier blocks 26 are spaced apart from the connecting part 23 and the elastic part 24 respectively. The barrier blocks 26 divide the adhesive storage tank 25 into a number of adhesive distribution tanks. The bottom of the barrier blocks 26 is pressed against the surface of the photovoltaic module 5, which plays a multi-effect role in preventing adhesive overflow.

[0054] The ends of the anti-overflow adhesive body 21, several blocking blocks 26 and inner buckle 241 are in a relatively sealed state on the surface of the photovoltaic module 5. The sealed space 31 formed can effectively store the overflow adhesive and prevent the overflow adhesive from overflowing from the anti-overflow adhesive body 21 to the surface of the photovoltaic module 5.
