Technical Field

[0001] The utility model belongs to the technical field of aluminum alloy frames, and in particular relates to a high-strength aluminum alloy frame of a solar cell assembly. Background Art

[0002] Solar cell modules are composed of high-efficiency monocrystalline / polycrystalline solar cells, low-iron ultra-white velvet tempered glass, packaging materials (EVA, POE, etc.), functional backplanes, interconnection strips, bus bars, junction boxes and aluminum alloy frames. The aluminum alloy frames used are used to fix and seal solar cell modules, enhance module strength, extend service life, and facilitate transportation and installation.

[0003] The four sides of the aluminum alloy frame in the prior art are mostly connected together by welding. This connection method is not convenient for disassembling other solar cell components wrapped and packaged in the aluminum alloy frame. In addition, the lack of corresponding reinforcement structure at the four corners makes it easy to be deformed by force, thereby affecting the strength of the aluminum alloy frame and being not conducive to use.

[0004] Therefore, a high-strength aluminum alloy frame for a solar cell assembly is needed to solve the problem in the prior art that the traditional aluminum alloy frame is not convenient for disassembling other solar cell assemblies wrapped and packaged in the aluminum alloy frame, and lacks corresponding reinforcement structure at the four corners, which makes it easy to deform under stress. Utility Model Content

[0005] The purpose of the utility model is to provide a high-strength aluminum alloy frame of a solar cell assembly to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-strength aluminum alloy frame of a solar cell assembly, comprising a first frame, wherein the first frames have two, and second frames are arranged on both sides of the middle position of the two first frames, and movable shafts are rotatably connected to both sides of the top surface of the first frame, and a sleeve is fixedly sleeved on the outer peripheral surface of the movable shaft, and a fixed shaft is provided at a position of the sleeve surface close to the second frame at an adjacent position, and an opening is inserted inside the fixed shaft, and the bottom of the opening is rotatably connected to the surface of the second frame at an adjacent position, and an inner warehouse is provided inside the sleeve, and a threaded rod is rotatably connected at the middle position of the inner warehouse, and a threaded sleeve is threadedly connected to the outer peripheral surface of the threaded rod, and two pins are fixed on one side of the threaded sleeve, and two insertion holes are provided through the surface of the opening, and one side of the pin passes through the sleeve at the adjacent position and extends to the inside of the insertion hole at the adjacent position.

[0007] It should be noted in the scheme that the top of the inner cavity surface of the inner warehouse is a rotating shaft, a first gear is fixedly sleeved at a position close to the rotating shaft on the outer circumference of the threaded rod, and a second gear is fixedly sleeved on the outer circumference of the rotating shaft, and the first gear and the second gear are meshingly connected.

[0008] It is further worth mentioning that the bottom of the inner cavity of the inner bin is connected to a limiting groove, the inner part of the limiting groove is slidably inserted into a limiting block, and the top of the limiting block passes through the limiting groove and is fixed to the surface of the bottom of the threaded sleeve.

[0009] It should be further explained that two storage grooves are provided on the side of the first frame and the side of the second frame, and a slider is slidably inserted inside the storage groove. A first spring telescopic rod is fixed to the position of the adjacent slider in the inner cavity of the storage groove, and the position of the surface of the first spring telescopic rod near the adjacent slider is fixed to the surface of the adjacent slider, and the second spring telescopic rod is fixed to the surface of the slider, and L-shaped baffles are provided on both sides of the two first frames.

[0010] As a preferred embodiment, the outer peripheral surface of the baffle is provided with a threaded section, the surface of the baffle is provided with two threaded holes, and the baffle is connected to the adjacent baffle through the threaded section and the adjacent threaded holes.

[0011] As a preferred embodiment, T-shaped positioning grooves are provided at both ends of the second frame near the adjacent first frame, and a T-shaped positioning block is inserted into the positioning groove, and one end of the positioning block passes through the adjacent positioning groove and is fixed to the surface of the adjacent first frame.

[0012] Compared with the prior art, the high-strength aluminum alloy frame of a solar cell assembly provided by the utility model has at least the following beneficial effects:

[0013] (1) After the two first frames and the second frames are placed together to form a frame structure, the sleeve is rotated so that the opening is embedded in the interior of the adjacent fixed shaft and the threaded sleeve is passed through the adjacent insertion hole. This not only allows the two adjacent first frames and the second frames to be able to stably form a frame structure and have their four corners have a certain pressure resistance, but also facilitates the separation of the first frame and the second frame, thereby facilitating the disassembly of other solar cell components wrapped and packaged by the two first frames and the second frames, thereby improving the practicality of the device.

[0014] (2) By setting four baffles, after the two second spring telescopic rods at adjacent positions are connected to the baffles at adjacent positions, the baffles are moved under the action of the resistance force to cause the second spring telescopic rods at adjacent positions and the first spring telescopic rod to deform, so that the force applied to the baffles can be reduced under the action of the rebound force of the first spring telescopic rod and the second spring telescopic rod, thereby reducing the force applied to the four corners of the frame structure formed by the first frame and the second frame, thereby further reducing the probability of the first frame and the second frame being deformed due to the force, thereby further improving the practicality of the device.

This not only makes the two adjacent first frames 1 and the second frames 2 able to stably form a frame structure, but also their four corners have a certain pressure resistance, and it is also convenient to separate the first frame 1 from the second frame 2, so as to facilitate the disassembly of other solar cell components wrapped and packaged in the two first frames 1 and the second frames 2.

[0023] Further as Figure 5 As shown, it is worth explaining in detail that the top of the inner cavity surface of the inner chamber 9 is a rotating shaft 17, and the outer circumference of the threaded rod 10 is fixedly sleeved with a first gear 16 near the rotating shaft 17, and the outer circumference of the rotating shaft 17 is fixedly sleeved with a second gear 18, and the first gear 16 and the second gear 18 are meshingly connected. The rotating shaft 17 is rotated by rubbing the second gear 18 with fingers, so that the threaded rod 10 can be rotated under the meshing action between the rotating shaft 17 and the limit block 15.

[0024] Further as Figure 3 As shown, it is worth explaining in detail that the bottom of the inner cavity of the inner bin 9 is connected to the limiting groove 14, the inner sliding of the limiting groove 14 is inserted into the limiting block 15, the top of the limiting block 15 passes through the limiting groove 14 and is fixed to the surface of the bottom of the threaded sleeve 11. Since the limiting block 15 can only slide on the inner cavity track of the limiting groove 14 at the adjacent position, it can limit the movement track of the threaded sleeve 11 and make it more stable during the horizontal movement.

[0025] Further as Figure 1 , Figure 5 and Figure 6As shown, it is worth specifically explaining that two storage grooves 20 are provided on the side of the first frame 1 and the side of the second frame 2, and a slider 21 is slidably inserted inside the storage groove 20, and a first spring telescopic rod 22 is fixed at a position of the inner cavity of the storage groove 20 near the adjacent position slider 21, and the surface of the first spring telescopic rod 22 is fixed to the surface of the adjacent position slider 21 at a position close to the adjacent position slider 21, and the surface of the slider 21 is fixed to the second spring telescopic rod 23, and an L-shaped baffle 19 is provided on both sides of the two first frames 1, and a threaded section 24 is provided on the outer peripheral surface of the baffle 19, and two threaded holes 25 are provided on the surface of the baffle 19, and the baffle 19 is connected to the adjacent position through the threaded section 24 and the threaded hole 25 The baffle 19 is connected, and through the cooperation of the threaded structure between the threaded section 24 arranged on the outer surface of the second spring telescopic rod 23 and the threaded hole 25 opened on the surface of the baffle 19, one baffle 19 can be arranged on one side of the first frame 1 and the second side of the second frame 2 to connect the two second spring telescopic rods 23, so that when the baffle 19 is subjected to a force, the baffle 19 can resist the second spring telescopic rod 23 to generate deformation, and the slider 21 slides in the inner cavity of the adjacent storage slot 20 to resist the adjacent first spring telescopic rod 22 to generate deformation, so that the force on the corner position of the frame structure formed by the first frame 1 and the second frame 2 can be reduced under the action of the rebound force of the first spring telescopic rod 22 and the second spring telescopic rod 23.

[0026] This scheme has the following working process: in actual use, when the user needs to splice the first frame 1 and the second frame 2 to form a frame structure, the frame structure is formed by placing the first frame 1 and the second frame 2 together, and then the angle of the adjacent position sleeve 4 is adjusted by rotating the movable shaft 3, so that the opening 6 can be embedded in the adjacent position fixed shaft 5, and then the second gear 18 is rubbed with fingers to rotate the rotating shaft 17, so that the threaded rod 10 can be rotated under the meshing action between the rotating shaft 17 and the limit block 15. Since the limit block 15 can only slide on the inner cavity trajectory of the adjacent position limit groove 14, it can limit the movement trajectory of the threaded sleeve 11 and make it more stable during the horizontal movement, so that the threaded sleeve 11 can move in the horizontal direction under the cooperation between the internal thread structure of its inner wall and the external thread structure of the outer peripheral surface of the threaded rod 10, so that the pin 12 can pass through the adjacent position inner bin 9 and extend to the inside of the adjacent position plug hole 13, so that it can limit the sleeve 4, so as to fix the frame structure formed by splicing. The utility model discloses a kind of utility model discloses a kind of utility model, and its fixed position is located at the corner position of the frame structure, so that the four corners of the frame structure have a certain pressure resistance effect, and at the same time, because this connection also facilitates the separation of the first frame 1 and the second frame 2, it is convenient to disassemble other solar cell components wrapped and packaged in the two first frames 1 and the second frame 2, and through the cooperation of the threaded structure between the threaded section 24 arranged on the outer peripheral surface of the second spring telescopic rod 23 and the threaded hole 25 opened on the surface of the baffle 19, a baffle 19 can be arranged on one side of the first frame 1 and the other side of the second frame 2. The two second spring telescopic rods 23 are connected, so that when the baffle 19 is subjected to the force, the baffle 19 can resist the second spring telescopic rod 23 to generate deformation, and the slider 21 slides in the inner cavity of the adjacent position storage slot 20 to resist the first spring telescopic rod 22 to generate deformation, so that the force at the corner position of the frame structure formed by the first frame 1 and the second frame 2 can be reduced under the action of the rebound force of the first spring telescopic rod 22 and the second spring telescopic rod 23, thereby further preventing the corner of the frame structure formed by the first frame 1 and the second frame 2 from deforming.

[0027] According to the above working process, it can be known that: after the two first frames 1 and the second frames 2 are placed together to form a frame structure, the sleeve plate 4 is rotated so that the opening 6 is embedded in the interior of the adjacent fixed shaft 5 and the threaded sleeve 11 is passed through the adjacent insertion hole 13, so that not only the two adjacent first frames 1 and the second frames 2 can be stably formed into a frame structure, but also the four corners thereof have a certain pressure resistance, and it is also convenient to separate the first frame 1 from the second frame 2, so as to facilitate the disassembly of other solar cell components wrapped and packaged by the two first frames 1 and the second frames 2, thereby improving the practicality of the device, through the four baffles 19, after the two second spring telescopic rods 23 at adjacent positions are connected to the baffle 19 at adjacent positions, the baffle 19 is moved under the action of the resistance force to deform the second spring telescopic rods 23 and the first spring telescopic rod 22 at adjacent positions, so that the force applied to the baffle 19 can be reduced under the action of the rebound force of the first spring telescopic rod 22 and the second spring telescopic rod 23, thereby reducing the force applied to the four corners of the frame structure formed by the first frame 1 and the second frame 2, thereby further reducing the probability of the first frame 1 and the second frame 2 being deformed by the force, thereby further improving the practicality of the device.

[0028] Further as Figure 4 As shown, it is worth explaining in detail that T-shaped positioning grooves 7 are provided at both ends of the second frame 2 near the adjacent first frame 1, and T-shaped positioning blocks 8 are inserted into the positioning grooves 7. One end of the positioning block 8 passes through the adjacent positioning groove 7 and is fixed to the surface of the adjacent first frame 1. When the first frame 1 and the second frame 2 are spliced, the two positioning blocks 8 on the surface of the first frame 1 are inserted into the adjacent positioning grooves 7, thereby positioning the first frame 1 and the second frame 2 before they are fixed after splicing, thereby further preventing them from separating.

[0029] In summary: after the two first frames 1 and the second frames 2 are placed together to form a frame structure, the sleeve plate 4 is rotated so that the opening 6 is embedded in the interior of the adjacent fixed shaft 5 and then the threaded sleeve 11 is passed through the adjacent insertion hole 13, so that not only the two adjacent first frames 1 and the second frames 2 can be stably formed into a frame structure, but also the four corners thereof have a certain pressure resistance, and it is also convenient to separate the first frame 1 from the second frame 2, so as to facilitate the disassembly of other solar cell components wrapped and packaged in the two first frames 1 and the second frames 2, thereby improving the practicality of the device, and through the arrangement of the four baffles 19, after the two second spring telescopic rods 23 at the adjacent positions are connected to the baffles 19 at the adjacent positions, when the baffles 19 are subjected to the resistance force Under the action, the second spring telescopic rod 23 and the first spring telescopic rod 22 at the adjacent positions are deformed, so that the force applied to the baffle 19 can be reduced under the action of the rebound force of the first spring telescopic rod 22 and the second spring telescopic rod 23, thereby reducing the force applied to the four corners of the frame structure formed by the first frame 1 and the second frame 2, thereby further reducing the probability of the first frame 1 and the second frame 2 being deformed by the force, thereby further improving the practicality of the device. When the first frame 1 and the second frame 2 are spliced, the two positioning blocks 8 on the surface of the first frame 1 are inserted into the interior of the positioning groove 7 at the adjacent positions, thereby positioning the first frame 1 and the second frame 2 before they are fixed after splicing, thereby further preventing them from separating.
