[0001] This utility model belongs to the field of solar cell module technology, specifically relating to a solar cell module. Background Technology

[0002] A solar cell module consists of high-efficiency crystalline silicon solar cells, ultra-white textured tempered glass, encapsulation materials, a backsheet, and an aluminum alloy frame.

[0003] When installing existing solar cell modules, the frame strips are separate and need to be assembled and connected individually. This results in too many seams in the frame installation, poor waterproofing, and water ingress into the solar cell module will greatly reduce its lifespan and operational reliability. In order to obtain greater power, multiple solar cell modules are often combined into a large-area solar panel. However, the existing solar cell module assembly and installation requires external tools, is cumbersome, and has poor connection stability.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a solar cell module.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, a solar cell module according to one embodiment of the present invention includes a frame 1. A fixing frame 3 is fixedly connected to one side end face of the frame 1. The fixing frame 3 is located in the area enclosed by the side edge of the frame 1. A first threaded hole 105 is provided on one side end face of the frame 1. A second threaded hole 302 matching the first threaded hole 105 is provided on one side end face of the fixing frame 3. A screw 301 is threadedly connected to the first threaded hole 105. The screw 301 is threadedly connected to the second threaded hole 302. The fixing frame 3 is fixed to the frame 1 by the screw 301.

[0031] A solar cell module body 2 is installed inside the side wall of frame 1, and the solar cell module body 2 abuts against the fixing frame 3. At the same time, a waterproof gasket 4 is attached to one end face of frame 1, and the solar cell module body 2 abuts against the waterproof gasket 4. In this way, the solar cell module body 2 is snapped between the fixing frame 3 and the waterproof gasket 4. The waterproof gasket 4 is a rubber sealing strip or a silicone sealing strip. There is a tight contact between the solar cell module body 2 and the waterproof gasket 4 without any gaps. Therefore, rainwater cannot enter the solar cell module from the seam on the upper surface of the solar cell module. At the same time, the fixing frame 3 is located below the solar cell module body 2 and is located inside frame 1. Therefore, rainwater cannot reach the connection between frame 1 and fixing frame 3, and thus cannot invade the solar cell module body 2 from the connection between frame 1 and fixing frame 3.

[0032] Furthermore, several water-guiding grooves 101 are provided on one side end face of the frame 1. When rainwater falls on the solar cell module, it flows down along the water-guiding grooves 101, so that rainwater will not accumulate on the surface of the solar cell module, further reducing the possibility of rainwater eroding into the interior of the solar cell module body 2.

[0033] like Figure 1 and Figure 7As shown, a plurality of connecting slots 102 are provided on one side end face of the frame 1. Connecting components 5 are inserted into the slot walls of the connecting slots 102. When multiple solar cell modules need to be connected into a whole, the connecting components 5 are inserted into the corresponding connecting slots 102 of two adjacent solar cell modules, thereby fixing the two adjacent solar cell modules together.

[0034] The connecting component 5 includes a connecting block 501, which is inserted into the corresponding connecting slots 102 of two adjacent solar cell modules. At the same time, a bolt 502 is welded to one end face of the connecting block 501, and a limiting washer 503 is sleeved on the bolt 502. The limiting washer 503 abuts against the back of the frame 1. A hand-tightening nut 504 is threaded onto the bolt 502, and the hand-tightening nut 504 abuts against the limiting washer 503. Since the limiting washer 503 abuts against the back of the frame 1, the connecting block 501 is fixed to the frame 1. At the same time, the limiting washer 503 can also support the frame 1 from the back, so that multiple frames 1 are kept in the same plane.

[0035] One end face of the connecting block 501 is chamfered, so that the connecting block 501 can be more easily inserted into the side wall of the connecting groove 102.

[0036] Furthermore, a plurality of first grooves 106 matching the connecting block 501 are provided on one side end face of the frame 1. The position of the first groove 106 corresponds to the position of the connecting groove 102. At the same time, the depth of the first groove 106 is the same as the thickness of the bottom edge of the connecting block 501. At this time, the top surface of the connecting block 501 and the top surface of the frame 1 are located in the same plane, so that the upper surface of the multiple solar cell modules connected into a whole remains flat and beautiful.

[0037] like Figure 5 and Figure 6As shown, a pair of first limiting grooves 103 are formed on one side end face of the frame 1. A limiting component is slidably connected within the groove wall of the first limiting groove 103. The limiting component includes an insert 6. A pair of second limiting grooves 104, matching the insert 6, are formed on one side end face of the frame 1. The second limiting grooves 104 are located on opposite end faces of the frame 1, and the positions of the first limiting grooves 103 and second limiting grooves 104 correspond. Therefore, when two solar cell modules are connected, the first limiting groove 103 on one solar cell module aligns with the opening of the second limiting groove 104 on the other solar cell module. At this time, the insert 6 is inserted into the second limiting groove 104 of the other solar cell module, thus ensuring that the two solar cell modules are on the same plane and that there is no misalignment at the connection point. A chamfer is formed on one side end face of the insert 6 to facilitate insertion of the insert 6 into the second limiting groove 104. A magnet block matching the plug 6 is pasted inside the groove wall of the second limiting groove 104. When the plug 6 is inserted into the second limiting groove 104, if the plug 6 is made of ferromagnetic material, the magnet block can generate a magnetic attraction force on the plug 6, so that the plug 6 will not slide inside the groove wall of the second limiting groove 104, thereby enhancing the stability of the solar cell module connection.

[0038] Each of the opposite end faces of the frame 1 has a first sliding groove 107 that matches the first limiting groove 103. A slider 601 is welded to one end face of the insert 6. The slider 601 is slidably connected to the groove wall of the first sliding groove 107. When the slider 601 slides, it can drive the insert 6 to slide. When it is necessary to connect two solar cell modules together, the slider 601 slides the insert 6 out, so that the insert 6 protrudes from the side of the frame 1, so that the insert 6 can be inserted into the second limiting groove 104 of the other solar cell module. An anti-slip groove is provided on one end face of the slider 601. The anti-slip groove can increase the friction between the finger and the slider 601, making it easier to slide the slider 601.

[0039] A second slide groove 108 is provided on the wall of the first slide groove 107. A limiting block 7 is slidably connected inside the wall of the second slide groove 108. A stop is provided at the opening of the second slide groove 108 to prevent the limiting block 7 from slipping out of the second slide groove 108. One end face of the first slide groove 107 is inclined. Several springs 8 are installed inside the wall of the second slide groove 108. One side of the spring 8 abuts against the wall of the second slide groove 108, and the other side of the spring 8 abuts against one end face of the limiting block 7. The limiting block 7 is held in place by the spring 8, so that one end face of the limiting block 7 abuts against the stop at the opening of the second slide groove 108. At this time, part of the end face of the limiting block 7 protrudes outside the second slide groove 108. When the insert 6 is slid outward, the slider 601 abuts against the inclined side of the limiting block 7, and the slider 601 pushes the limiting block 7 into the second slide groove 108. After the slider 601 slides past the limiting block 7, the insert 6 no longer presses against the limiting block 7. The spring 8 pushes the limiting block 7 so that the limiting block 7 protrudes outside the second slide groove 108. One end face of the limiting block 7 abuts against the end face of the slider 601, preventing the slider 601 from sliding, thereby fixing the insert 6 so that the insert 6 can be inserted into the second limiting groove 104. When it is necessary to disconnect the connection between the solar cell modules, press the limiting block 7 so that the limiting block 7 is completely retracted into the second slide groove 108, and then slide the slider 601, thereby driving the insert 6 to retract into the first limiting groove 103.

[0040] When using, such as Figure 1As shown, the frame 1 is a single unit with no seams on its upper surface. The solar cell module body 2 is installed inside the frame 1. A waterproof gasket 4 is installed at the connection between the frame 1 and the solar cell module body 2. The waterproof gasket 4 fills the gap at the connection between the frame 1 and the solar cell module body 2, thereby enhancing the sealing at the connection and preventing rainwater from entering the frame 1 from the connection. It also prevents rainwater from seeping downwards from the upper surfaces of the frame 1 and the solar cell module body 2. Rainwater cannot penetrate the upper surface of the solar cell module. At the same time, a water guide channel 101 is provided on the upper surface of the frame 1, allowing rainwater to flow down along the channel. Rainwater cannot accumulate on the upper surface of the solar cell module, further reducing the possibility of rainwater intruding into the solar cell module body 2 from the connection between the frame 1 and the solar cell module body 2, thus further improving the rainproof performance of the solar cell module. To obtain greater power generation, multiple solar cell modules need to be assembled and used together. First, push the slider 601, which causes the insert 6 to slide outward, so that the insert 6 protrudes from the side of the frame 1. Align the opening of the second limiting groove 104 of another solar cell module with the insert 6, so that the part of the insert 6 protruding from the side of the frame 1 is inserted into the second limiting groove 104 of the other solar cell module. At this time, the connecting grooves 102 of the two solar cell modules correspond to each other. Insert the connecting block 501 into the corresponding connecting grooves 102 of the two solar cell modules, thereby fixing the two solar cell modules together. Then, fit the limiting washer 503 onto the bolt 502, and then tighten the hand nut 504 so that the limiting washer 503 is tightly attached to the back of the two solar cell modules, thereby fixing the two solar cell modules together and increasing the stability and reliability of the connection between the solar cell modules.
