Description

Technical Field

[0001] This utility model relates to the field of battery casings, specifically to a reinforcement structure for lithium-ion battery casings. Background Technology

[0002] In the field of battery safety technology, the reliability of the battery's casing structure, as a core component of energy storage, directly affects the safe operation of the entire system. With the rapid development of new energy vehicles, energy storage systems, and other fields, battery application scenarios are becoming increasingly complex, significantly increasing the requirements for the casing's impact and deformation resistance. Existing battery casings generally adopt traditional frame-type reinforcement solutions, mainly by increasing the casing wall thickness or local reinforcing ribs to improve structural strength. However, these solutions still have limitations in protecting against multi-directional external forces and long-term vibration conditions.

[0003] Traditional battery casing reinforcement structures often employ an integral frame design or welded reinforcing ribs to the outside of the casing. However, this method makes it difficult to achieve a balanced distribution of stress in all directions, which can easily lead to casing deformation when local stress is concentrated. Furthermore, the direct welding method makes the reinforcement components and the casing form an inseparable integral structure, requiring the entire unit to be replaced when a part is damaged, resulting in high maintenance costs. At the same time, the installation and positioning methods of traditional reinforcement components are singular, making it impossible to flexibly adjust the reinforcement strength and coverage according to actual working conditions, and making it difficult to form an effective collaborative protection system in complex stress environments. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings and provide a lithium-ion battery casing reinforcement structure that can provide all-round reinforcement during reinforcement. This solves the technical problems of existing technologies, such as inconvenience in disassembly during reinforcement, high maintenance costs, and difficulty in achieving balanced distribution of stress in all directions on the casing.

[0005] The objective of this utility model is achieved through the following means:

[0006] A lithium-ion battery casing reinforcement structure includes a base plate. First hinge blocks are installed at each of the four corners of the upper surface of the base plate. Reinforcing flaps are hinged to the inner sides of each of the first hinge blocks via bearings. A battery casing is installed in the center of the upper surface of the base plate. Side rods are welded to the outer center of each reinforcing flap. A cross seat is snapped into the top of each side rod. Insert plates are movably inserted into the left and right sides of the cross seat. Connecting seats are installed at the outer ends of each insert plate. A reinforcement frame is connected to the bottom of each connecting seat. First bolts are screwed onto the top of the cross seat at positions corresponding to the insert plates. Second bolts are screwed onto the top of the cross seat at positions corresponding to the side rods.

[0007] Furthermore, the lower part of the second bolt is screwed into the inside of the side rod, and the number of the first bolts is 1-3 sets, with the lower part of each first bolt screwed into the inside of the insert plate, which improves the precision of the assembly.

[0008] Furthermore, the inner side of the reinforced flap is equipped with protruding strips, which enhance the strength of the reinforced flap. There are 3-6 sets of protruding strips. A second mounting block is welded to the upper outer side of the reinforced flap. A first mounting block is connected to the outer side of the end cover of the battery casing at the position corresponding to the second mounting block.

[0009] Furthermore, hooks are connected to the outer side of the first mounting block, and second hinge blocks are connected to the upper outer side of the second mounting block. Handles are attached to the outer side of the second hinge blocks via bearings.

[0010] Furthermore, each handle has a horizontally inserted shaft inside, and each shaft has a hanging ring on both sides. The hanging ring is engaged with the inside of the hook. By placing the hanging ring on the outside of the hook and then pressing down on the handle, the reinforcing flap and the battery casing can be connected and positioned, ensuring that the reinforcing flap fits tightly against the side of the battery casing and effectively disperses external impact forces.

[0011] Furthermore, rubber pads are laid on the lower surface of the cross seat and the inner side of the reinforcement frame. The outer edges of the reinforcement flip-plate cross seat and the reinforcement frame are rounded. The added rubber pads prevent the cross seat and the reinforcement frame from causing excessive pressure marks on the battery casing.

[0012] The beneficial effects of this utility model are as follows: After the cover plate of the battery casing is sealed, the reinforcing flap is pushed to adhere to the outer wall of the battery casing. The cross seat and side rod are assembled and fixed with a second bolt. Then, the insert plate is inserted into the interior of the cross seat and fixed with a first bolt. Thus, the outer periphery and top of the battery casing are reinforced in all directions by the reinforcing flap, cross seat, and reinforcing frame, forming a synergistic effect. This enhances the overall load-bearing capacity of the casing. Through the all-round reinforcement design, the risk of deformation and cracking of the battery casing due to external forces is effectively reduced, thereby avoiding damage such as squeezing and puncture to the internal cells. This improves the safety and reliability of the battery. Furthermore, since the reinforcing flap, cross seat, and reinforcing frame are modular reinforcement structures, they are easy to maintain and replace later. They can be easily disassembled for repair or replacement, reducing the overall maintenance cost. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] In this embodiment, refer to Figures 1-6The specific implementation of the lithium-ion battery casing reinforcement structure includes a base plate 1. First hinge blocks 2 are installed at each of the four corners of the upper surface of the base plate 1. Reinforcing flaps 3 are hinged to the inner sides of each of the first hinge blocks 2 via bearings. A battery casing 4 is installed in the center of the upper surface of the base plate 1. Side rods 5 are welded to the center of the outer sides of each reinforcing flap 3. A cross seat 6 is snapped onto the top of each side rod 5. Insert plates 7 are movably inserted into the left and right sides of the interior of the cross seat 6. Connecting seats 8 are installed at the outer ends of each insert plate 7. The bottom of each connecting seat 8 is connected to a reinforcing bracket 9. A first bolt 10 is screwed onto the top of the cross seat 6 at a position corresponding to the insertion plate 7. A second bolt 11 is screwed onto the top of the cross seat 6 at a position corresponding to the side rod 5. The lower part of the second bolt 11 is screwed into the inside of the side rod 5. There are 1-3 sets of first bolts 10, and the lower part of each first bolt 10 is screwed into the inside of the insertion plate 7. Rubber pads are laid on the lower surface of the cross seat 6 and the inner side of the reinforcing bracket 9. The reinforcing flap 3... The outer edges of the connector 6 and the reinforcement frame 9 are rounded. After the cover of the battery casing 4 is sealed, the reinforcement flap 3 is pushed to stick to the outer wall of the battery casing 4. The cross connector 6 and the side rod 5 are assembled and fixed with the second bolt 11. The insert plate 7 is inserted into the cross connector 6 and fixed with the first bolt 10. Thus, the outer periphery and top of the battery casing 4 are reinforced in all directions by the reinforcement flap 3, the cross connector 6 and the reinforcement frame 9, forming a synergistic effect. This enhances the overall load-bearing capacity of the casing. The all-round reinforcement design effectively reduces the risk of deformation and cracking of the battery casing due to external forces, thereby avoiding damage such as squeezing and puncture to the internal cells, improving the safety and reliability of the battery. Furthermore, since the reinforcement flap 3, the cross connector 6 and the reinforcement frame 9 are modular reinforcement structures, they are easy to maintain and replace later. They can be easily disassembled for repair or replacement, reducing the overall maintenance cost.

[0022] The inner side of the reinforced flap 3 is equipped with 3-6 sets of protruding strips 19. The upper outer side of the reinforced flap 3 is welded with a second mounting block 13. The outer side of the end cap of the battery casing 4 is connected to a first mounting block 12 at a position corresponding to the second mounting block 13. The outer side of the first mounting block 12 is connected with a hook 14. The upper outer side of the second mounting block 13 is connected with a second hinge block 15. The outer side of the second hinge block 15 is connected to a handle 16 by bearing. The inside of the handle 16 is horizontally inserted with a shaft 18. The two sides of the inside of the shaft 18 are equipped with hanging rings 17. The hanging rings 17 are engaged with the inside of the hook 14. By placing the hanging rings 17 on the outside of the hook 14 and then pressing down the handle 16, the reinforced flap 3 and the battery casing 4 can be connected by the hanging rings 17 and the hook 14, thus ensuring that the reinforced flap 3 fits tightly with the side of the battery casing and effectively disperses the external impact force.

[0023] After the cover plate of the battery casing 4 is sealed, the reinforcing flap 3 is pushed to adhere to the outer wall of the battery casing 4. The cross seat 6 and side rod 5 are assembled and fixed with the second bolt 11. Then, the insert plate 7 is inserted into the cross seat 6 and fixed with the first bolt 10. Thus, the reinforcing flap 3, cross seat 6, and reinforcing frame 9 provide comprehensive reinforcement to the outer perimeter and top of the battery casing 4, forming a synergistic effect that enhances the overall load-bearing capacity of the casing. This comprehensive reinforcement design effectively reduces the risk of deformation and cracking of the battery casing due to external forces. This design avoids damage to the internal cells such as compression and puncture, improving the safety and reliability of the battery. Furthermore, the modular design of the reinforcing flap 3, cross seat 6, and reinforcing frame 9 facilitates later maintenance and replacement, allowing for individual disassembly, repair, or replacement, thus reducing overall maintenance costs. Additionally, by placing the hanging ring 17 on the outside of the hook 14 and then pressing down the handle 16, the reinforcing flap 3 and the battery casing 4 can be connected through the hanging ring 17 and the hook 14, ensuring a tight fit between the reinforcing flap 3 and the side of the battery casing, effectively dispersing external impact forces.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
