Technical Field

[0002] The conversion efficiency of perovskite solar cells has increased from 3.8% in 2009 to 25.2% in just 11 years, showing a generally positive development trend. However, the degradation of perovskite in humid environments remains a challenging issue. Among various influencing factors, moisture is considered one of the biggest challenges.

[0003] For example, Chinese patent CN213583853U discloses a packaging structure for a leakage-proof perovskite solar cell module. However, this structure includes an insulating outer shell, an insulating inner shell installed at the center of the bottom of the inner shell, a solar cell module body installed at the bottom of the inner shell, an insulating sealing cover installed on the top of the inner shell, a fourth sealing layer installed at the center of the lower surface of the insulating sealing cover, and the fourth sealing layer located inside the inner shell. The bottom of the fourth sealing layer abuts against the top of the solar cell module body, and the outer wall of the fourth sealing layer is interference-fitted with the inner wall of the inner shell. Both the inner shell and the insulating sealing cover are installed in a groove. Chinese utility model patent with publication number CN213583853U can effectively insulate and seal the body of solar cell modules, effectively reducing the possibility of leakage during use and installation, and facilitating the disassembly, repair or replacement of solar cell modules by staff. However, in actual application, due to the different sizes and thicknesses of different battery modules, it is impossible to fix battery modules of different thicknesses inside the casing. To solve the above problems, we propose a perovskite battery module encapsulation structure. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a packaging structure for perovskite battery modules, which solves the problem that battery modules of different thicknesses cannot be fixed inside the casing due to differences in their body size and thickness.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] By adopting the above technical solution and setting a fixing component, the fixing component can fix the extension frame to the top surface of the placement block, which facilitates the later encapsulation of battery module bodies of different thicknesses.

[0008] The fixing component includes: a plurality of rotating slots, all of which are formed on the top surface of the placement block; a plurality of rotating holes are formed on the top surface of the extension frame, the rotating holes corresponding to the interior of the rotating slots; a connecting rod, the connecting rod being threaded into the interior of the rotating holes, the bottom end of the connecting rod passing through the rotating holes and threadedly connected to the rotating slots; and a positioning element, the positioning element being disposed on the top surface of the protective plate for positioning the protective plate.

[0009] By adopting the above technical solution and setting positioning components, the protective plate can be positioned so that it can be fixed on the top surface of the extension frame.

[0010] Preferably, the positioning element includes: a plurality of positioning grooves, all of which are formed on the top surface of the protective plate, and an extension hole is formed on the bottom surface inside the positioning groove, the extension hole corresponding to the position of the rotating hole; a fixing bolt, the fixing bolt being movably installed inside the positioning groove, the fixing bolt being movably sleeved with the extension hole, and the bottom end of the fixing bolt passing through the extension hole and threadedly connected to the rotating hole.

[0011] By adopting the above technical solution and setting up a placement block, after the worker fixes the battery module body inside the placement slot, and then places the extension frame on the top surface of the placement block, it is convenient to extend the height of the placement block later, so as to place battery module bodies of different thicknesses inside the placement slot and facilitate the subsequent sealing of battery module bodies of different thicknesses.

[0012] Preferably, the top surface of the connecting rod is provided with a hexagonal groove, the top surface of the placement block and the top surface of the extension frame are provided with a plurality of limiting grooves, and the bottom surface of the protective plate and the bottom surface of the extension frame are fixedly connected with a plurality of limiting blocks, the limiting blocks and the limiting grooves being movably fitted together.

[0013] By adopting the above technical solution and setting connecting rods, when the staff places the extension frame on the top surface of the placement block, the staff can then connect the placement block and the extension frame together using several connecting rods. This makes it easier to fix the extension frame on the top surface of the placement block and also facilitates the staff to fix multiple extension frames later.

[0014] Preferably, the sealing assembly includes: a mounting groove formed on the top surface of the placement block, and a sealing groove formed on the top surface of the extension frame; two sealing frames, which are respectively movably fitted inside the mounting groove and the sealing groove; and a collection element disposed on the top surface of the placement block for collecting moisture.

[0015] By adopting the above technical solution and setting a sealing component, the sealing component can seal the inside of the placement tank, thereby preventing water stains from entering the inside of the placement tank and affecting the later service life of the battery pack.

[0016] Preferably, the collecting component includes: a collecting groove formed on the top surface of the placement block, and a fixing groove formed on the top surface of the extension frame; and two filter frames, which are respectively fixedly installed inside the collecting groove and inside the fixing groove.

[0017] By adopting the above technical solution and setting up a collection device, the collection device can filter and collect moisture in the air.

[0018] Preferably, the bottom surface of the fixing groove is provided with several connecting holes, the bottom surface of the collecting groove is provided with several water outlet holes, a miniature one-way valve is fixedly connected inside the water outlet hole, a protective block is movably fitted inside the extension frame, a protective groove is provided on the bottom surface of the protective block, the protective groove is movably fitted together with the battery assembly body, and a sealing ring is fixedly connected to the bottom surface of the protective block.

[0019] By adopting the above technical solution, by setting a sealing frame, two sealing frames can seal the space between the placement block and the extension frame and the extension frame and the protective plate. At the same time, by setting a filter frame, the filter frame can absorb moisture in the humid air, thereby preventing moisture from adhering to the outer circular wall of the sealing frame and forming water stains that seep into the interior of the placement groove, effectively sealing the interior of the placement groove and improving the service life of the battery assembly body in the later stage.

[0020] Preferably, the top surface of the protective block has two positioning holes, the top surface of the protective plate has two mounting holes, the positioning holes and the mounting holes are positioned corresponding to each other, two conductive posts are fixedly connected inside the mounting holes, the bottom ends of the conductive posts pass through the positioning holes and are electrically connected to the battery assembly body, and several support legs are fixedly connected to the bottom surface of the placement block.

[0021] By adopting the above technical solution and setting a protective block, after the protective plate is fixed on the top surface of the extension frame, the protective plate can squeeze the protective block, so that the bottom surface of the protective block is tightly attached to the bottom surface inside the placement groove through the sealing ring, further waterproofing and moisture-proofing the battery module body and improving the service life of the battery module body.

[0022] In summary, the present invention mainly has the following beneficial effects:

[0023] By setting up a placement block, after the worker fixes the battery assembly body inside the placement slot, and then places the extension frame on the top surface of the placement block, it is easy to extend the height of the placement block later. This facilitates the placement of battery assembly bodies of different thicknesses inside the placement slot, making it convenient to encapsulate battery assembly bodies of different thicknesses later. By setting up connecting rods, after the worker places the extension frame on the top surface of the placement block, the worker connects the placement block and the extension frame together with several connecting rods, making it easy to fix the extension frame on the top surface of the placement block. This also facilitates the worker to fix multiple extension frames later. At this time, the worker uses fixing bolts and rotating holes to connect them together, so that the protection plate can be fixed to the extension frame for fixation, thus encapsulating the battery assembly body inside the placement slot.

[0024] By setting up sealing frames, two sealing frames can seal the space between the placement block and the extension frame, and between the extension frame and the protective plate. At the same time, by setting up filter frames, moisture in the humid air can be absorbed, thereby preventing moisture from adhering to the outer circular wall of the sealing frames and forming water stains that seep into the interior of the placement groove. This effectively seals the interior of the placement groove and improves the service life of the battery pack. By setting up protective blocks, when the protective plate is fixed to the top surface of the extension frame, the protective plate can squeeze the protective block, so that the bottom surface of the protective block is tightly attached to the bottom surface of the placement groove through the sealing ring. This further waterproofs and prevents moisture from entering the battery pack, thus improving the service life of the battery pack. Attached Figure Description
