Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a quick-assembly and disassembly packaging structure for a split lithium battery pack. Background Technology

[0002] Split-type lithium battery packs are widely used in modern electric vehicles, energy storage systems and other fields. Traditional lithium battery packs are complex and inefficient to disassemble and replace, and the packaging structure has certain safety hazards. In order to improve disassembly and assembly efficiency and ensure battery safety, rapid disassembly and assembly of the packaging structure has become an urgent technical problem to be solved. This technology aims to simplify the disassembly and assembly process, improve work efficiency, and enhance the safety and reliability of the battery pack.

[0003] However, in actual use, the following shortcomings still exist. For example, the existing split-type lithium battery pack quick-disassembly and packaging structure cannot achieve quick positioning and installation of lithium battery packs and convenient locking of the cover, thus failing to improve operational efficiency. Positioning and installation time is increased. Without a precise positioning structure, the lithium battery pack needs to be repeatedly adjusted when placed in the box. Especially in scenarios with multiple battery packs, alignment deviations are prone to occur, and the installation time for a single installation may be extended several times, significantly increasing labor costs. Installation stability is difficult to guarantee. Inaccurate positioning can lead to poor contact between the battery pack and the box, which may cause problems such as loose conductive connections and reduced heat dissipation efficiency, thereby increasing the probability of failure and indirectly reducing the overall system operating efficiency. Frequent disassembly and assembly exacerbate wear. Repeated adjustments and forced alignment will accelerate component wear, shorten the service life of the structure, and increase the frequency of maintenance and replacement. In the long run, this further reduces the overall utilization efficiency of the equipment.

[0004] Therefore, this utility model proposes a split-type lithium battery pack quick disassembly and assembly packaging structure to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-assembly and disassembly packaging structure for split-type lithium battery packs.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a split-type lithium battery pack quick-disassembly and packaging structure, including a split-type lithium battery pack, and further comprising: The encapsulation assembly includes a housing disposed outside a split lithium battery pack, a housing cover disposed on the housing, a fixing block connected to the top side of the housing, a slot formed on the fixing block, a locking block connected to the side of the housing cover near the slot, the locking block disposed within the slot, a support block connected to the fixing block, a limit block rotatably connected to the support block, a connecting block connected to the side of the housing cover near the support block, a limit groove formed on the connecting block, and the limit block disposed at the top of the limit groove; The engaging assembly includes a fixing post connected to the bottom of the split lithium battery pack, a first magnetic block disposed inside the fixing post, a spring piece disposed on the first magnetic block, a limiting seat connected to the bottom of the housing, a second magnetic block connected inside the limiting seat, and the first magnetic block disposed on the second magnetic block.

[0007] Furthermore, the box cover is threaded with bolts, which are threaded onto the fixing block.

[0008] The beneficial effects of adopting the above-mentioned further solution are: the cover and the fixing block are connected by bolt threads. After the limiting block is initially locked, tightening the bolts can further enhance the connection strength between the cover and the box body. The self-locking characteristic of the thread prevents the cover from loosening and improves the stability of the packaging structure.

[0009] Furthermore, a sealing gasket is connected between the box body and the box cover, and the box cover fits tightly against the sealing gasket when closed.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the sealing gasket between the box body and the box cover is squeezed and deformed when the box cover is closed, tightly filling the gap between the two, blocking external dust and moisture from entering the interior, forming a sealing barrier, protecting the split lithium battery pack from environmental factors, and ensuring its working stability.

[0011] Furthermore, one end of the spring is fixedly connected to the top of the inner wall of the fixed column, and the other end of the spring is fixedly connected to the upper surface of the first magnetic block.

[0012] The beneficial effects of adopting the above-mentioned further solution are: one end of the spring is connected to the top of the inner side wall of the fixing column, and the other end is connected to the upper surface of the first magnetic block. When the first magnetic block and the second magnetic block are attracted, the spring is compressed to generate elastic force, which acts in the opposite direction on the magnetic block, reduces the gap between the magnetic blocks, enhances the tightness of the magnetic connection, and prevents the lithium battery pack from shaking.

[0013] Furthermore, a magnetic ring is connected to the lid, and a positioning post is provided inside the magnetic ring.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the magnetic ring on the cover and the positioning post form a magnetic conductive connection, the positioning post is inserted into the positioning hole of the lithium battery pack to achieve precise docking, and the magnetic ring forms a conductive path by magnetic force, which not only achieves positioning and fixation, but also ensures stable current transmission.

[0015] Furthermore, the top of the cover is provided with heat dissipation fins.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the heat dissipation fins on the top of the cover increase the contact area with the air, and the heat generated by the lithium battery pack is transferred to the fins through the cover, and the heat is dissipated by air convection, which accelerates the heat dissipation speed and prevents the battery pack from being affected by overheating.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, during the installation of the split-type lithium battery pack, the first magnetic block of the bottom fixing post and the second magnetic block of the bottom limiting seat of the box are attracted by opposite poles. The spring is pressed and generates a reverse force, which enhances the connection stability. At the same time, the magnetic force assists the guide, so that the battery pack is accurately aligned. When the box cover is closed, the locking block is embedded in the locking groove of the fixing block, and the limiting block on the support block is rotated to press it against the top of the limiting groove of the connecting block, locking the box cover. This realizes the rapid positioning and installation of the lithium battery pack and the convenient locking of the box cover, improving the operation efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-5As shown, this embodiment provides a technical solution: a split-type lithium battery pack quick-assembly and disassembly packaging structure, including a split-type lithium battery pack 1, and further including: The encapsulation component 2 includes a housing 21 disposed outside the split lithium battery pack 1. A housing cover 22 is disposed on the housing 21. A fixing block 23 is connected to the side of the housing 21 near the top. A slot 24 is provided on the fixing block 23. A locking block 25 is connected to the side of the housing cover 22 near the slot 24. The locking block 25 is disposed in the slot 24. A support block 26 is connected to the fixing block 23. A limiting block 27 is rotatably connected to the support block 26. A connecting block 28 is connected to the side of the housing cover 22 near the support block 26. A limiting groove 29 is provided on the connecting block 28. The limiting block 27 is disposed on the top of the limiting groove 29. The locking assembly 3 includes a fixing post 31 connected to the bottom of the split lithium battery pack 1. A first magnetic block 33 is disposed inside the fixing post 31, and a spring piece 32 is disposed on the first magnetic block 33. A limiting seat 34 is connected to the bottom of the housing 21, and a second magnetic block 35 is connected inside the limiting seat 34. The first magnetic block 33 is disposed on the second magnetic block 35. When the split lithium battery pack 1 is installed, the first magnetic block 33 of the bottom fixing post 31 and the second magnetic block 35 of the limiting seat 34 at the bottom of the housing 21 are attracted by opposite polarities. The spring piece 32 is pressed and generates a reverse force, which enhances the connection stability. At the same time, the magnetic force assists the guide, so that the battery pack is accurately aligned. When the cover 22 is closed, the locking block 25 is embedded in the locking groove 24 of the fixing block 23. The limiting block 27 on the support block 26 is rotated so that it presses against the top of the limiting groove 29 of the connecting block 28, locking the cover 22. This realizes the rapid positioning and installation of the lithium battery pack and the convenient locking of the cover 22, improving the operation efficiency.

[0022] like Figures 1-3 As shown, the cover 22 is threaded with bolts 210, which are threaded onto the fixing block 23. The cover 22 and the fixing block 23 are threaded together by bolts 210. After the limiting block 27 is initially locked, tightening bolts 210 can further enhance the connection strength between the cover 22 and the box body 21. The self-locking characteristic of the thread prevents the cover 22 from loosening and improves the stability of the packaging structure. A sealing gasket 211 is connected between the box body 21 and the cover 22. When the cover 22 is closed, it fits tightly with the sealing gasket 211. The sealing gasket 211 between the box body 21 and the cover 22 is squeezed and deformed when the cover 22 is closed, tightly filling the gap between the two, blocking external dust and moisture from entering the interior, forming a sealing barrier, protecting the split lithium battery pack 1 from environmental factors and ensuring its working stability. like Figures 1-3 as well as Figure 5As shown, one end of the spring piece 32 is fixedly connected to the top of the inner wall of the fixing post 31, and the other end of the spring piece 32 is fixedly connected to the first magnetic block 33. On the upper surface, one end of the spring piece 32 is connected to the top of the inner wall of the fixing post 31, and the other end is connected to the upper surface of the first magnetic block 33. When the first magnetic block 33 and the second magnetic block 35 are attracted, the spring piece 32 is compressed to generate elastic force, which acts in the opposite direction on the magnetic block, reducing the gap between the magnetic blocks, enhancing the tightness of the magnetic connection, and preventing the lithium battery pack from shaking. A magnetic ring 36 is connected to the cover 22, and a positioning post 37 is set inside the magnetic ring 36. The magnetic ring 36 and the positioning post 37 on the cover 22 form a magnetic conductive connection. The positioning post 37 is inserted into the positioning hole of the lithium battery pack to achieve precise docking. The magnetic ring 36 forms a conductive path by tightly fitting with magnetic force, which not only achieves positioning and fixation but also ensures stable current transmission. A heat dissipation fin 38 is set on the top of the cover 22. The heat dissipation fin 38 on the top of the cover 22 increases the contact area with the air. The heat generated by the lithium battery pack is transferred to the fins through the cover 22, and the heat is dissipated by air convection, which accelerates the heat dissipation speed and prevents the battery pack from being affected by overheating.

[0023] Working principle: like Figures 1-5 As shown, firstly, during the installation phase of the split lithium battery pack 1, the fixing post 31 at the bottom of the split lithium battery pack 1 cooperates with the limiting seat 34 at the bottom of the housing 21. The first magnetic block 33 inside the fixing post 31 and the second magnetic block 35 inside the limiting seat 34 generate a basic fixing force due to the attraction of opposite poles. At the same time, the two ends of the spring piece 32 are respectively connected to the top of the inner side wall of the fixing post 31 and the upper surface of the first magnetic block 33. After being pressed, it generates a reverse elastic force, further reducing the gap between the magnetic blocks, enhancing the tightness of the connection, and effectively preventing the battery pack from shaking. The magnetic force also assists in guidance, ensuring accurate alignment during installation. During the sealing process, when the housing cover 22 is closed, the locking block 25 on the housing cover 22 is embedded into the locking groove 24 of the fixing block 23 of the housing 21 to form a preliminary positioning. The limiting block 27 on the support block 26 is rotated to press it against the top of the limiting groove 29 of the connecting block 28, completing the preliminary locking of the housing cover 22. Then it is tightened. The bolts 210 between the cover 22 and the fixing block 23 utilize the self-locking characteristic of the threads to further strengthen the connection and prevent the cover 22 from loosening. The sealing gasket 211 between the box body 21 and the cover 22 is deformed by compression, tightly filling the gap and forming a sealing barrier to block the intrusion of external dust and moisture, protecting the internal battery pack. During operation, the magnetic ring 36 on the cover 22 and the positioning post 37 work together. The positioning post 37 is inserted into the positioning hole of the battery pack to achieve precise docking. The magnetic ring 36 forms a stable conductive path by magnetic force, which not only ensures current transmission but also enhances the positioning and fixing effect. At the same time, the heat generated by the battery pack is transferred through the cover 22 to the heat dissipation fins 38 on the top. The heat dissipation fins 38 increase the contact area with the air and quickly dissipate heat with the help of air convection, preventing the battery pack from being affected by overheating and affecting its performance and lifespan, thus ensuring the stable operation of the system in all aspects.
