Description

Technical Field

[0001] This utility model relates to the field of batteries, and in particular to a sealing ring for batteries. Background Technology

[0002] Currently, lithium-ion cylindrical batteries have gradually become the mainstream product in the new energy industry due to their advantages such as high energy density, high charge and discharge rate and good capacity consistency. Among them, the cylindrical battery sealing process is indispensable in the manufacturing process of lithium-ion cylindrical batteries.

[0003] Currently, when sealing rings are installed on one end of a battery, they are manufactured as part of a set and installed on the battery. However, when batteries of different diameters are available, different sealing rings need to be prepared for battery assembly, which makes the subsequent installation process too troublesome and wastes resources in the production process. Therefore, a sealing ring for batteries is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a sealing ring for batteries, which solves the problem that current sealing rings are not suitable for installing batteries of different diameters.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A sealing ring for batteries, comprising:

[0007] A bottom ring and a sealing ring fixed at the top of the bottom ring near its outer edge;

[0008] A sealing assembly includes an annular groove formed on the inner wall of the sealing ring and a fitting member movable inside the annular groove. The fitting member is generally annular in structure. Two movable ring blocks are provided inside the annular groove, and the inner rings of the two movable ring blocks are fitted to the outer ring of the fitting member. A spring is provided inside the annular groove, and the two ends of the spring abut against the inner wall of the annular groove and the movable ring blocks, respectively.

[0009] Furthermore, the middle part of the bonding component is configured as a bonding opening.

[0010] Furthermore, the bonding element is configured as a flexible structure.

[0011] Furthermore, both of the movable ring blocks are configured as semi-ring structures, and the spacing between the two movable ring blocks at their joints is set.

[0012] Furthermore, a groove is provided on the inner wall of the sealing ring near the bottom, and the groove is located below the sealing assembly.

[0013] Furthermore, the slot is provided with two limiting plates inside, and the cross-section of the two limiting plates is L-shaped.

[0014] Furthermore, clamping grooves are provided on the cross arms of both limiting plates, and the distance between the two limiting plates is set.

[0015] Furthermore, both sides of the outer side of the sealing ring are threaded with adjusting rods. One end of the adjusting rod passes through the sealing ring and extends into the groove. The end of the adjusting rod located inside the groove is rotatably connected to the vertical arm of the limiting plate.

[0016] Furthermore, a bottom opening is provided in the middle of the bottom ring.

[0017] Furthermore, a sealing opening is provided in the middle of the sealing ring, and the sealing opening is connected to the bottom opening.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Through the sealing ring and sealing assembly, the sealing assembly can achieve a sealing effect by ensuring that the inner ring of the sealing component is always pressed and adhered to the outer surface of the battery according to the diameter of the battery. That is, when one end of the battery is inserted into the sealing ring, the outside of the battery will press the fitting component. Since the fitting component has elasticity, it presses the movable ring block, which compresses the spring. Due to the great elastic force of the spring, the spring extends and pushes the movable ring block, which in turn pushes the fitting component to move, so that the fitting component is tightly attached to the outer surface of batteries of different diameters.

[0020] 2. By adjusting the rods and limiting plates, the distance between the two limiting plates can be adjusted by the two adjusting rods, so as to adapt to the diameter of the battery according to the size of the distance between the two limiting plates. Thus, after the battery is inserted into the sealing ring, the two limiting plates clamp and fix the batteries of different diameters. Attached Figure Description

Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] This utility model embodiment provides a sealing ring for a battery. Please refer to [link / reference]. Figures 1-5The device includes: a bottom ring 1 and a sealing ring 2 fixed at the top of the bottom ring 1 near the outer edge; it also includes a sealing assembly, which includes an annular groove 3 formed in the inner wall of the sealing ring 2 and a fitting member 6 movable inside the annular groove 3. The fitting member 6 is generally annular in structure. The annular groove 3 is provided with two movable ring blocks 5, and the inner rings of the two movable ring blocks 5 are fitted to the outer rings of the fitting member 6. The annular groove 3 is provided with a spring 4, and the two ends of the spring 4 abut against the inner wall of the annular groove 3 and the movable ring blocks 5, respectively.

[0033] like Figures 1-5 As shown, the bottom ring 1 serves as the basic support structure for the entire sealing ring, providing a stable mounting surface and load-bearing base for the sealing ring. The sealing ring 2 plays the main sealing role, preventing the leakage of electrolyte and other substances inside the battery through cooperation with other battery components, while also preventing external impurities from entering the battery's internal surface.

[0034] The annular groove 3 provides installation space for other components of the sealing assembly. The mating part 6 is the part of the sealing assembly that directly contacts the surface of the battery component that needs to be sealed. By tightly fitting the surface of the component, the sealing function is achieved.

[0035] The movable ring blocks 5 serve to support and guide the bonding component 6. They are attached to the outer ring of the bonding component 6, which can restrict the movement direction of the bonding component 6 in the ring groove 3, so that it can only move within a specific range. At the same time, they provide a certain support force for the bonding component 6, ensuring that the bonding component 6 can stably adhere to the surface of the battery component when subjected to pressure.

[0036] Spring 4 provides elastic force to movable ring 5, which in turn transmits the elastic force to the bonding component 6. This elastic force enables the bonding component 6 to always maintain a tight fit with the surface of the battery component. Even when the internal pressure of the battery changes or is affected by external vibration, the elastic deformation of spring 4 can compensate for the sealing gap and maintain good sealing performance.

[0037] Overall operation process: During battery assembly, the sealing ring is installed in the corresponding position, the bottom ring 1 is fixed to the battery mounting surface, and the sealing ring 2 initially contacts other battery components that need to be sealed. At this time, the bonding component 6 in the sealing assembly is in a state of waiting to be sealed under its own movement characteristics and the support and guidance of the movable ring block 5. When the battery is used or subjected to assembly pressure, the bonding component 6 moves closer to and fits against the surface of the battery component under pressure. The movable ring block 5 slides in the ring groove 3 to provide stable support for the bonding component 6. At the same time, the spring 4 is compressed or elastically deformed according to pressure changes, and elastic force is applied to the bonding component 6 through the movable ring block 5, so that the bonding component 6 is always tightly fitted against the surface of the battery component, achieving a reliable seal. During battery use, no matter how the internal pressure changes or is affected by external vibrations, the spring 4 can adjust the sealing state through its own elastic deformation to ensure the durability and stability of the sealing effect.

[0038] Please see Figure 1 and Figure 5 The middle part of the bonding component 6 is set as the bonding port 601. The bonding component 6 is set as a flexible structure. Both movable ring blocks 5 are set as semi-ring structures. The spacing between the two movable ring blocks 5 at their joints is set.

[0039] like Figure 1 and Figure 5 As shown, the fitting port 601 provides a channel space for the connection between the inside and outside of the battery or for the interaction between specific structures inside the battery and the outside. During the use of the battery, there may be situations where internal electrodes and other structures are connected to external circuits. The fitting port 601 can meet these functional requirements without affecting the overall sealing performance of the sealing ring. That is, after the battery is inserted into the fitting port 601, the fitting part 6 is pressed against the outer surface of the battery, ensuring that the overall sealing ring structure is properly fitted onto the battery.

[0040] The flexible bonding component 6 can better adapt to the shape and unevenness of the battery component surface. Since the surface of the battery may have slight unevenness or shape deviation during manufacturing and use, the flexible bonding component 6 can fill these gaps through its own deformation to achieve a tighter fit, thereby improving the sealing effect. The flexible structure can be set as a rubber structure.

[0041] The semi-ring structure of the movable ring block 5 facilitates installation and disassembly. When installing the movable ring block 5 into the ring groove 3, the two semi-ring structures can be placed into their respective positions in the ring groove 3 and then assembled. This is more convenient and faster than the integral structure. Similarly, when maintenance or replacement of the movable ring block 5 is required, it can be more easily removed from the ring groove 3. The spacing between the two movable ring blocks 5 provides a certain amount of space and flexibility for their movement within the ring groove 3. When the mating part 6 is deformed or moved under pressure, the movable ring block 5 can make slight adjustments within the spacing range to better adapt to the movement of the mating part 6, ensuring its support and guidance. The spacing of the movable ring block 5 allows it to better cooperate with the movement of the mating part 6, improving the overall performance and stability of the sealing assembly and further enhancing the sealing effect of the sealing ring.

[0042] Please continue reading. Figure 1 , Figure 3 and Figure 5 A groove 7 is provided on the inner wall of the sealing ring 2 near the bottom. The groove 7 is located below the sealing assembly. Two limiting plates 8 are provided inside the groove 7. The cross-section of the two limiting plates 8 is L-shaped. Clamping grooves are provided on the horizontal arms of the two limiting plates 8. The distance between the two limiting plates 8 is set.

[0043] like Figure 1 , Figure 3 and Figure 5 As shown, the slot 7 provides specific space for the subsequent installation of other components, such as the limiting plate 8, so that these components can be reasonably arranged in the sealing ring 2 without affecting the normal operation of the sealing assembly, while still fulfilling their own functions.

[0044] The L-shaped limiting plate 8 provides a stable mounting base for other possible components, such as the adjusting rod 9, so that these components can be firmly connected to the sealing ring 2, ensuring the normal operation of the entire sealing system.

[0045] The clamping slot provides a clamping and fixing position for the battery, achieving a stable connection and fixation. The spacing between the two limiting plates 8 provides space for adjustment and operation. During installation and maintenance, the battery clamped in the clamping slot can be adjusted or replaced through this spacing, and it is also convenient to observe the situation inside the slot 7.

[0046] Please see Figure 1 and Figure 5 Both sides of the outer side of the sealing ring 2 are threaded with adjusting rods 9. One end of the adjusting rod 9 passes through the sealing ring 2 and extends into the groove 7. The end of the adjusting rod 9 located inside the groove 7 is rotatably connected to the vertical arm of the limiting plate 8.

[0047] like Figure 1 and Figure 5As shown, the threaded connection allows the adjusting rod 9 to be rotated outside the sealing ring 2, thereby adjusting its position. This design introduces an adjustable mechanism to the entire sealing ring system, enabling precise control of the relevant components inside the sealing ring according to actual usage conditions.

[0048] The adjusting rod 9 can establish a connection with the components in the slot 7, transmitting external adjustment actions to the key areas inside the sealing ring, thereby achieving control over the internal structure.

[0049] The rotating connection allows the rotational motion of the adjusting rod 9 to be converted into the movement or other actions of the limiting plate 8. When the adjusting rod 9 rotates, it drives the limiting plate 8 to move accordingly within the slot 7 through the rotating connection point, thereby adjusting the position and state of the limiting plate 8.

[0050] Please see Figure 1 and Figure 2 The bottom ring 1 has a bottom opening 101 in the middle, and the sealing ring 2 has a sealing opening 201 in the middle, which is connected to the bottom opening 101.

[0051] like Figure 1 and Figure 2 As shown, the bottom opening 101 provides space for the installation of internal battery components, and also provides a channel for possible material exchange or energy transfer between the inside and outside of the battery. During battery assembly, key components such as the battery electrodes can be installed and fixed through the bottom opening 101 to ensure the integrity of the battery structure.

[0052] The sealing port 201 is connected to the bottom port 101. While ensuring the basic sealing function of the sealing ring, it provides a channel for the flow of specific substances inside the battery or the realization of specific functions. The sealing port 201 can cooperate with other sealing structures or components inside the battery to form a complete sealing system, ensuring that the battery will not leak during normal operation.

[0053] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
