Description

Technical Field

[0001] This invention relates to the field of packaging technology, and more specifically, to an N-type TOPCON battery module packaging structure. Background Technology

[0002] A search revealed that patent CN220577957U discloses an N-type TOPCON battery module packaging structure, which solves the problems that most existing N-type TOPCON battery module packaging structures are packaged manually using aluminum plates and glue, and then packed into sealed boxes for transportation. However, the glue is very sticky, which is time-consuming and inconvenient to use during disassembly and assembly.

[0003] The aforementioned device addresses some of the problems described in the background technology. However, its structure still requires multiple bolts for fixation, making assembly and disassembly time-consuming and labor-intensive. This is primarily because the bolts are typically tightened to a specific preload, which allows them to withstand the loads of the structure or equipment during operation. However, disassembly requires overcoming this preload, necessitating considerable force and tools to loosen the bolts. Therefore, an N-type TOPCON battery module encapsulation structure is needed to solve these problems. Summary of the Invention

Two grooves are symmetrically formed at both ends of the card plate, and a transverse sliding plate is slidably fitted inside each groove. A suction cup is fixedly connected to the side of the transverse sliding plate. The card plate is provided with a driving component for driving the transverse sliding plate to move outward so that the suction cup is tightly attached to the inner wall of the mounting ear.

[0010] Preferably, the drive assembly includes a main rod fixed to the bottom of the traction rod, a columnar groove is provided on the card plate, the bottom end of the main rod passes through the card plate and extends into the columnar groove, a pressure plate that slides in the columnar groove is fixedly connected to the bottom end of the main rod, and an airbag that is fixedly connected to the bottom wall of the columnar groove is fixedly connected to the bottom of the pressure plate.

[0011] Preferably, cylindrical grooves are provided on both sides of the card plate, and a piston is slidably connected in the cylindrical groove.

[0012] Preferably, two locking rods are symmetrically fixedly connected to the bottom of the end face of the traction rod with the main rod as the center. Two slots are symmetrically opened on the top of the locking plate for the two locking rods to engage. A silicone tube is glued and fixed inside the slot. The locking rod is inserted into the silicone tube and fixed, and can be separated.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. This invention achieves rapid packaging and disassembly of battery components through the design of inserts and slots in the assembly and disassembly components, as well as the cooperation between magnetic plates and magnets.

At the same time, the tight cooperation between inserts and slots, along with the locking function of magnetic plates, ensures the stability of the packaging.

[0015] 2.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] The packaging structure proposed in publication number CN220577957U, while addressing the technical drawback of inconvenient assembly and disassembly to some extent, still requires multiple bolts for fixation, making assembly and disassembly still relatively time-consuming and labor-intensive. Please refer to [link / reference]. Figures 1-6 This embodiment provides an N-type TOPCON battery module packaging structure, which enables rapid packaging and disassembly of the battery module, greatly improving packaging efficiency and reducing manual operation time. Simultaneously, the tight fit between the insert and the slot, along with the locking function of the magnetic plate, ensures the stability of the packaging. The packaging structure consists of two end-face sealing plates 1 and two side sealing plates 2, assembled with a pull rod 3. The inner side of the end-face sealing plate 1 has an end inner groove 11, and the inner side of the side sealing plate 2 has a side inner groove 21. The width of the end inner groove 11 and the side inner groove 21 is the same as the vertical height of the TOPCON battery module.

[0029] refer to Figures 3-4As shown, the existing device has solved the problems in the background technology to a certain extent, but its structure still needs to be fixed with multiple bolts, which makes its disassembly and assembly still relatively time-consuming and laborious. The main reason is that the bolts are usually tightened to achieve a specific preload. This preload allows the bolts to withstand the load of the structure or equipment during operation. However, this preload needs to be overcome during disassembly, which requires a lot of force and tools to loosen the bolts. In order to achieve rapid encapsulation and disassembly of the encapsulation structure, the following settings are made: the top of the two end face sealing plates 1 is provided with a pull rod 3. The pull rod 3 also serves to shield and protect the upper surface of the TOPCON battery module. The two end-face sealing plates 1 and the side sealing plate 2 are assembled into a disassembly assembly 4 with an opening on the upper and lower end faces of the encapsulation structure. The disassembly assembly 4 includes a magnetic plate 41 located at the bottom of the end face of the pull rod 3. The side of the end-face sealing plate 1 is fixedly connected to a mounting ear 42. The bottom of the mounting ear 42 is fixedly connected to a magnet 43 fixedly connected to the side of the end-face sealing plate 1. The magnet 43 attracts the magnetic plate 41. The end face of the side sealing plate 2 is fixedly connected to an insert plate 44. The side of the end-face sealing plate 1 has a slot 45 for the insert plate 44 to be engaged. An auxiliary assembly 46 is provided between the magnetic plate 41 and the pull rod 3 to strengthen the assembly of the encapsulation structure. In use, the side sealing plate 2 is first placed on both sides of the TOPCON battery module, allowing the battery module to fall into the inner side groove 21. Then, the end sealing plate 1 is placed on the front and rear ends of the TOPCON battery module, allowing the insert plate 44 of the side sealing plate 2 to be inserted into the slot 45 of the end sealing plate 1. Then, the magnetic plates 41 at the bottom of both ends of the pull rod 3 are inserted into the mounting ears 42 and attracted to the magnets 43 below the mounting ears 42, so that the pull rod 3 limits the end sealing plate 1, preventing the end sealing plate 1 from pulling the slot 45 out of the insert plate 44 forward or backward. The slot 45 and the insert plate 44 restrict the position of the side sealing plate 2, thereby achieving the encapsulation of the TOPCON battery module during transportation. This has the beneficial effects of improving encapsulation efficiency, enhancing module protection, simplifying operation process, environmental protection and energy saving, and low cost.

[0030] Example 2

[0031] Based on Example 1, and referring to Figures 5-6As shown, the vibration and bumps of the vehicle during transportation will affect the fixation of the magnetic plate 41 and the magnet 43. Even though the magnetic plate 41 and the magnet 43 themselves have strong adsorption force, under frequent vibration and bumps, there is a probability that the magnetic plate 41 will become unstable or separate from the surface of the magnet 43. In order to improve the stability and safety of the TOPCON battery pack during transportation, the following settings are made: an auxiliary assembly 46 for strengthening the assembly stability of the encapsulation structure is set between the magnetic plate 41 and the pull rod 3. The auxiliary assembly 46 includes a clamping plate 461 fixed to the top of the magnetic plate 41 and snapped into the mounting ear 42. Two grooves are symmetrically opened at both ends of the clamping plate 461. A transverse plate 466 is slidably fitted inside the two grooves. A suction cup 467 is fixedly connected to the side of the transverse plate 466. The top of the clamping plate 461 is provided with a tool for driving the transverse plate 466 to move outward so that the suction cup 467 is in contact with the inner wall of the mounting ear 42. The drive assembly includes a main rod 462 fixed to the bottom of the end face of the pull rod 3. The inner wall of the clamping plate 461 has a columnar groove. The bottom end of the main rod 462 penetrates the inner wall of the clamping plate 461 and extends into the interior of the columnar groove. The bottom end of the main rod 462 is fixedly connected to a pressure plate 4621 that is slidably connected to the inner wall of the columnar groove. The bottom of the pressure plate 4621 is fixedly connected to an airbag 463 that is fixedly connected to the bottom wall of the columnar groove. The circumference of the bottom end of the airbag 463 is symmetrically connected to two transmission pipes 4631. Both sides of the clamping plate 461 have cylindrical grooves. A piston 464 is slidably connected in the cylindrical groove. One side of the piston 464 is fixedly connected to a connecting rod 465 that is fixedly connected to the side of the transverse plate 466. A transmission pipe 4631 that communicates with the cylindrical groove is provided on one side of the airbag 463. The air in the airbag 463 acts on the piston 464 through the transmission pipe 4631 to make it slide in a specific direction. The magnetic plates 41 at the bottom of both ends of the pull rod 3 attract the magnets 43 inside the mounting ears 42, providing initial positioning for the pull rod 3. This magnetic positioning ensures the stability of the pull rod 3 during the packaging process, preventing it from moving or deviating from its intended position during operation. As the pull rod 3 continues to move downward, the main rod 462 is gradually placed into the cylindrical groove, causing the pressure plate 4621 to compress the air bladder 463. The gas inside the air bladder 463 is then transferred through two transmission pipes 4631 to two cylindrical grooves, where pistons 464 are installed. The pistons 464 are gradually displaced in opposite directions by the gas. This mechanism not only controls the pressure plate 4621 but also... The movement of the piston 464 and the connecting rod 465 ensures synchronous displacement, which in turn pushes the transverse plate 466 until the suction cup 467 is tightly attached to the inner wall of the mounting ear 42, generating an adsorption force that firmly fixes the suction cup 467 to the inner wall of the mounting ear 42. This adsorption force can resist the influence of external forces, which helps to enhance the fixation and adsorption force between the magnetic plate 41 and the magnet 43. It can effectively reduce the problem of the magnetic plate 41 falling off under frequent vibration and bumps, provide additional support and stability, and reduce the gap between the surfaces of the magnetic plate 41 and the magnet 43, thereby reducing the risk of instability caused by vibration.

[0032] refer to Figures 5-6 As shown, two locking rods 468 are symmetrically fixed to the bottom of the end face of the pull rod 3, with the main rod 462 as the center. Two slots 469 are symmetrically opened on the top of the locking plate 461 for the two locking rods 468 to engage. A silicone tube 4691 is glued and fixed inside the slots 469. The locking rods 468 are inserted into and fixed within the silicone tubes 4691, and can be separated. As the main rod 462 is gradually inserted into the cylindrical groove, the locking rods 468 are simultaneously and gradually inserted into the silicone tubes 4691 within the slots 469. When the suction cup 467 adheres to the inner wall of the mounting ear 42, the locking rods 468 are fully inserted into the silicone tubes 469. Inside, the silicone tube 4691 has a certain degree of elasticity and adhesion, which can effectively fix the position of the locking rod 468. When the locking rod 468 is fully inserted into the silicone tube 4691, its specific shape or structure will generate friction or mutual locking mechanism with the tube wall, preventing the pull rod 3 from accidentally moving or falling out of the expected position during operation. Through the cooperation of the locking rod 468 and the silicone tube 4691, the pull rod 3 can maintain a stable position after encapsulation, ensuring the tight adsorption of the suction cup 467 and the inner wall of the mounting ear 42, locking the position of the pull rod 3, and ensuring the stability of the final encapsulated part.

[0033] according to Figures 1-6 As shown, in use, the side sealing plate 2 is first placed on both sides of the TOPCON battery assembly, allowing the TOPCON battery assembly to fall into the side inner groove 21. Then, the end sealing plate 1 is placed on both ends of the TOPCON battery assembly, with the insert plate 44 of the side sealing plate 2 inserted into the slot 45 of the end sealing plate 1. Next, the magnetic plates 41 at both ends of the pull rod 3 are inserted into the mounting ears 42. The magnetic plates 41 are then initially locked in position by the magnets 43 below the mounting ears 42, thus limiting the end sealing plate 1 and preventing it from moving forward or backward and causing the slot 45 to come off the insert plate 44. The slot 45 and the insert plate 44 restrict the position of the side sealing plate 2. This enables the encapsulation of the TOPCON battery module during transportation. The pull rod 3 also serves to shield and protect the upper surface of the TOPCON battery module. After the pull rod 3 is initially positioned, it continues to move downward, causing the main rod 462 to gradually enter the cylindrical groove. The pressure plate 4621 squeezes the air bag 463, causing the gas in the air bag 463 to be transmitted to the two cylindrical grooves through the two transmission pipes 4631, pushing the piston 464. This causes the connecting rod 465 to push the transverse plate 466 until the suction cup 467 is adsorbed onto the inner wall of the mounting ear 42. At the same time, the pull rod 3 can maintain a stable position during the encapsulation process through the cooperation of the locking rod 468 and the silicone tube 4691, locking the position of the pull rod 3 and ensuring the stability of the final encapsulation.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
