Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of battery top covers, in particular to a middle top cover of a battery with pole column protection. Background Art
[0002] The battery top cover and pole column are key components to ensure the function and safety of the battery. The top cover is mainly responsible for protecting the interior of the battery from external influences, such as dust and water protection, and improving the safety of use through an integrated explosion-proof valve or open circuit protection device. The pole column is responsible for efficient current conduction, and its material and structural design have a direct impact on the performance and life of the battery. The optimization of the design and materials of these components is the key to improving battery efficiency and safety.
[0003] In the existing battery design, the middle top cover of the battery usually has preset pole column holes so that the pole columns can extend out and be connected to other components in the battery pack. However, when the battery is impacted or strongly vibrated during use or transportation, the pole columns may shake or tilt within the pole column holes. Since the pole columns are usually made of relatively fragile materials, this shaking or tilting may cause the pole columns to bump against the inner walls of the pole column holes, resulting in damage or deformation of the pole columns. The damage to the pole columns may not only affect the electrochemical performance of the battery but also cause an internal short circuit of the battery, further leading to safety accidents. Therefore, in view of the above deficiencies, a middle top cover of a battery with pole column protection is proposed to solve the above problems. Summary of the Utility Model

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0040] Refer to Figures 1 to 3 , an embodiment provided by the present invention: A battery middle top cover with pole protection includes a battery top cover 1. A plurality of first chutes 2 are opened inside the battery top cover 1. Slide bars 3 are slidably connected inside each of the plurality of first chutes 2. The first chutes 2 are used to accommodate the slide bars 3, and the chutes ensure that the slide bars 3 can slide smoothly. The outside of the slide bars 3 is slidably connected inside the battery top cover 1. A first spring 4 is sleeved outside each of the plurality of slide bars 3. The movement of the slide bars 3 is controlled by the first spring 4. When the slide bars 3 move, the spring is compressed or released. One end of the first spring 4 is fixedly connected inside the battery top cover 1, and the other end of the first spring 4 is fixedly connected to the outside of a fixed ring 5. A fixed ring 5 is fixedly connected to the outside of each of the plurality of slide bars 3. Clamping rings 6 are fixedly connected to one side of each of the plurality of slide bars 3 away from the first spring 4. Rubber rings 7 are fixedly connected to one side of each of the plurality of clamping rings 6 away from the fixed ring 5. The clamping rings 6 are connected to the rubber rings 7 and are used to clamp and protect the pole under the action of the spring. The rubber rings 7 are used to directly contact the pole, and their materials have flexibility and a certain friction coefficient to ensure reliable clamping force without damaging the pole;
[0041] Refer to Figure 2 - Figure 4, at the top of each of the multiple fixed rings 5, a sliding rod 8 is fixedly connected. At the top of each of the multiple sliding rods 8, a first sliding plate 9 is fixedly connected. The bottom of the first sliding plate 9 is slidably connected to the top of the battery top cover 1. When the first sliding plate 9 is pushed by an operator, power is transmitted through the sliding rod 8, causing the fixed ring 5 and the sliding rod 3 to displace, thereby compressing the first spring 4 and causing the clamping ring 6 and the rubber ring 7 to move correspondingly to adapt to and clamp the terminal post. Inside the battery top cover 1, multiple first sliding grooves 10 are provided. The outside of the fixed ring 5 is slidably connected inside the first sliding grooves 10. At the bottom of the battery top cover 1, multiple sealing rings 11 are fixedly connected. On the top side inside the battery top cover 1, multiple sliding grooves 12 are provided. The outside of the sliding rod 8 is slidably connected inside the sliding grooves 12. At the bottom of the battery top cover 1, an alignment plate 13 is fixedly connected. At the bottom of the battery top cover 1, a sealing assembly for enhancing sealing is provided.
[0042] Referring to Figure 3 - Figure 5 , the sealing assembly includes a battery box body 14. The battery box body 14 is the outer shell for accommodating the battery. The inside of the battery box body 14 is slidably connected to the outside of the alignment plate 13. Inside the battery box body 14, multiple second sliding plates 15 are slidably connected. The top of the second sliding plates 15 is in contact with the bottom of the battery top cover 1. At the bottom of each of the multiple second sliding plates 15, multiple second springs 16 are fixedly connected. Here, this design can keep the second sliding plates 15 stable by means of the second springs 16. On the adjacent sides of the multiple second sliding plates 15, rotating plates 17 are rotatably connected. Inside each of the multiple rotating plates 17, a sliding shaft 18 is rotatably connected. The outside of the sliding shaft 18 is slidably connected inside the battery box body 14. Inside the battery box body 14, multiple second sliding grooves 19 are provided. The outside of the second sliding plates 15 is slidably connected inside the second sliding grooves 19. Inside the battery box body 14, multiple second sliding slots 20 are provided. Here, the design of the second sliding slots 20 is used as the sliding space for the rotating plates 17. The rotation of the rotating plates 17 is driven by the second sliding plates 15, and the rotating plates 17 move within the second sliding slots 20. The sliding shafts 18 inside the rotating plates 17 slide inside the battery box body 14 to provide support for the rotating plates 17. The outside of the rotating plates 17 is slidably connected inside the second sliding slots 20. On the adjacent sides of the multiple rotating plates 17, sealing strips 21 are rotatably connected. When the rotating plates 17 rotate, the sealing strips 21 are pushed towards the alignment plate 13, increasing the pressure at the sealing part and improving the sealing effect. At the top of the battery top cover 1, a handle 22 is rotatably connected. The inside of the sealing strips 21 is slidably connected to the outside of the alignment plate 13.
[0043] Working principle: When encapsulating the battery, first place the battery inside the battery box body 14. Then, the battery top cover 1 can be aligned with the top of the battery box body 14 through the handle 22 and pressed down. During this process, the first sliding plate 9 can be slid, causing the fixed ring 5 to displace, which will result in the sliding rod 3 sliding inside the first chute 2. Due to this action, the first spring 4 will be compressed, and the clamping ring 6 and the rubber ring 7 will displace. Next, when the battery terminal enters between the rubber rings 7, the first sliding plate 9 can be released. With the elastic force of the first spring 4, the rubber ring 7 can clamp and fix the terminal, thus achieving the protection of the terminal. As the battery top cover 1 drops, its bottom will squeeze the second sliding plate 15 to displace downward, thereby causing the second spring 16 to be compressed. As the second sliding plate 15 displaces, it will cause the rotating plate 17 to rotate. As the rotating plate 17 rotates, the sliding shaft 18 will slide inside the battery box body 14. At this time, the rotating plate 17 will squeeze the sealing strip 21, thereby increasing the pressure at the sealing part and improving the sealing effect. Subsequently, the battery top cover 1 and the battery box body 14 can be fixed with bolts.
[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
