[0002] The electrode post is a component that serves as a conductive medium in electronic or electrical devices, and its function is to input or output current.

[0003] Through a large number of searches, the disclosure number CN208094831U discloses a split type electrode post, which realizes splicing design by dividing the whole into parts, shortens the processing cycle, reduces the time cost, and has directionality of thermal conductivity and electrical conductivity. It can be personalized designed according to actual needs, so as to meet the requirement of passing larger current on smaller cross section, and reduce the thermal conductivity to achieve the purpose of energy saving. At the same time, the composite material can adjust its density according to the requirement, so as to change its thermal conductivity and electrical conductivity to meet the requirement of different occasions.

[0004] In the prior art, although the electrode post can be assembled, it still takes a long time to assemble after the production of each component is completed, so a lithium battery electrode post structure with edge rolling is needed to solve the above problems. UTILITY MODEL CONTENT

[0005] The utility model aims at providing a lithium battery electrode post structure with edge rolling, which has the advantages of improving assembly efficiency and shortening production time, and solves the problem of long assembly time affecting production efficiency in the prior art.

[0007] The positioning hole opening position matches the protrusion setting position, the protrusion passes through the positioning hole and is fixedly connected with the limiting plate.

[0008] Preferably, the inner wall of the shell is provided with internal threads at the bottom, the shell is made of stainless steel, and the shell has a rectangular structure after being unfolded. The internal threads provided at the bottom of the inner wall of the shell provide a convenient threaded connection for the installation of the positioning ring, thereby enhancing the stability and sealing performance of the structure. The selection of stainless steel material makes the shell have good corrosion resistance and mechanical strength, and can withstand various environments and pressures during battery operation. The design of the shell having a rectangular structure after being unfolded facilitates processing and manufacturing, and also facilitates subsequent winding operations.

[0009] Preferably, the electrode cap is sleeved on the top of the shell after being wound, and the top of the electrode cap has a circular truncated cone structure. The design of the top of the electrode cap having a circular truncated cone structure not only looks beautiful, but also increases the contact area between the electrode cap and the external connecting member of the battery, thereby improving the current transmission efficiency.

The length of the limiting plate matches the distance between the electrode cap and the opposite side of the positioning ring, thereby ensuring that the limiting plate can completely cover the open part on the shell, improving the overall integrity and stability of the structure. The arc structure design enables the limiting plate to have a closer contact with the shell, thereby reducing looseness and wear caused by vibration or external force.

[0012] Preferably, the first step groove and the second step groove have matching sizes, and the shell is wound into a cylindrical structure through the first step groove and the second step groove. The design of the first step groove and the second step groove having matching sizes enables the shell to be easily wound into a cylindrical structure, and the wound shell has high stability and strength. This design not only simplifies the processing and manufacturing process of the shell, but also improves the overall performance and reliability of the electrode column.

[0013] Preferably, the front end of the protruding block passes through the positioning hole and extends into the limiting hole, and the protruding block in the limiting hole is connected with the limiting plate by hot melting.

[0027] Positioning hole 221 opening position and lug 211 setting position are matched, and lug 211 passes through positioning hole 221 and is fixedly connected with limiting plate 4.

[0028] Specifically, shell 2 is designed as coiled cylindrical structure, and this design not only simplifies the manufacturing process of shell 2, but also makes the assembling process more intuitive and efficient.The inner wall and the outer wall of shell 2 are respectively provided with first step groove 21 and second step groove 22, and these step grooves not only provide guidance for the coiling of shell 2, but also realize the quick fixed connection between shell 2 and limiting plate 4 through the matching design of lug 211 and positioning hole 221.

[0029] In the assembling process, lug 211 is fixedly connected with limiting hole 41 on limiting plate 4 through the positioning hole 221 on second step groove 22.This design not only simplifies the assembling steps, but also ensures the accurate positioning and firm connection between the components.

[0030] In addition, the design of the electrode cap 1 and the positioning ring 3 also further improves the assembly efficiency. The electrode cap 1 is sleeved on the top of the shell 2, and can be fixed through simple sleeving operation, without the need for additional connection steps.

This connection method is not only firm and reliable, but also easy to operate, greatly improving the assembly speed.

[0031] In summary, the lithium battery electrode post structure with rolled edge realizes fast and accurate connection between various components through unique design, significantly improves the assembly efficiency, and thus shortens the production time. This improvement not only reduces the production cost, but also improves the overall performance and reliability of the electrode post, providing strong support for the production and application of lithium batteries. In addition, this structure solves the problem of long time consumption affecting the production efficiency during the assembly operation in the prior art. By simplifying the assembly steps and reducing the assembly error, the structure makes the production of the electrode post more efficient and reliable, meeting the demand of modern industry for efficient production.

[0032] Example Two

[0033] In order to improve the stability of the assembled electrode post, as shown in Figure 1 , Figure 3 and Figure 4 , in this embodiment, an internal thread 23 is provided at the bottom of the inner wall of the shell 2. The shell 2 is designed with stainless steel material, and the shell 2 is in a rectangular structure after being unfolded. The internal thread 23 provided at the bottom of the inner wall of the shell 2 in the design provides a convenient threaded connection method for the installation of the positioning ring 3, enhancing the stability and sealing performance of the structure. The selection of stainless steel material makes the shell 2 have good corrosion resistance and mechanical strength, and can withstand various environments and pressures during battery operation. The design of the shell 2 in a rectangular structure after being unfolded facilitates processing and manufacturing, and also facilitates subsequent winding operation.

[0034] Further, the electrode cap 1 is sleeved on the top of the shell 2 after being wound, and the top of the electrode cap 1 is designed in a circular truncated cone structure. The design of the top of the electrode cap 1 in a circular truncated cone structure not only looks beautiful, but also can increase the contact area between the electrode cap 1 and the external connecting piece of the battery, improving the current transmission efficiency. In addition, the circular truncated cone structure also helps to firmly install the electrode cap 1 on the top of the shell 2, preventing it from falling off due to vibration or external force.

[0035] Further, the positioning ring 3 is designed in a convex shape in longitudinal section, and external threads are arranged on the top of the outer wall of the positioning ring 3, and the positioning ring 3 is screwed to the bottom of the shell 2 after winding. In the design, the positioning ring 3 is designed in a convex shape in longitudinal section, which makes the positioning ring 3 closely fit on the bottom of the shell 2, preventing the leakage of electrolyte. The external threads on the top of the outer wall of the positioning ring 3 match the internal threads 23 on the bottom of the inner wall of the shell 2, achieving the firm connection of the positioning ring 3 and the shell 2. This threaded connection method is not only simple and easy to implement, but also has high reliability and durability.

[0036] Further, a plurality of limiting holes 41 are equidistantly arranged on the limiting plate 4, the length of the limiting plate 4 matches the distance between the electrode cap 1 and the side of the positioning ring 3 opposite to the limiting plate 4, and the contact surface between the limiting plate 4 and the shell 2 is designed in an arc shape. In the design, the limiting holes 41 equidistantly arranged on the limiting plate 4 provide a passage for the protrusions 211 to pass through, and also limit the position of the limiting plate 4 on the shell 2. The length of the limiting plate 4 matches the distance between the electrode cap 1 and the side of the positioning ring 3 opposite to the limiting plate 4, ensuring that the limiting plate 4 can completely cover the open part on the shell 2, improving the overall integrity and stability of the structure. The arc-shaped design makes the contact between the limiting plate 4 and the shell 2 more closely, reducing the looseness and wear caused by vibration or external force.

[0037] Further, the first step groove 21 and the second step groove 22 are matched in size, and the shell 2 is wound into a cylindrical structure through the first step groove 21 and the second step groove 22. In the design, the first step groove 21 and the second step groove 22 are matched in size, which makes the shell 2 easily wound into a cylindrical structure, and the wound shell 2 has high stability and strength. This design not only simplifies the processing and manufacturing process of the shell 2, but also improves the overall performance and reliability of the electrode column.

[0038] Further, the protrusions 211 pass through the positioning holes 221 and extend into the limiting holes 41, and the protrusions 211 in the limiting holes 41 are heat-welded to the limiting plate 4. In the design, the protrusions 211 pass through the positioning holes 221 and extend into the limiting holes 41, which achieves the fixed connection of the limiting plate 4 and the shell 2. The protrusions 211 and the limiting plate 4 are firmly combined together through heat-welding, further enhancing the stability and durability of the structure. This connection method is not only simple and easy to implement, but also has high reliability and anti-vibration performance.

[0039] The utility model discloses a lithium battery electrode post structure with a rolled edge, which comprises a shell 2, an electrode cap 1, a positioning ring 3 and a limiting plate 4. The shell 2 is a hollow cylinder structure, and the top of the inner wall of the shell 2 is provided with a first stepped groove 21, and the bottom of the inner wall of the shell 2 is provided with a second stepped groove 22. The electrode cap 1 is a circular truncated cone structure, and the top of the electrode cap 1 is provided with a positioning hole 221. The positioning ring 3 is a hollow cylinder structure, and the outer wall of the positioning ring 3 is provided with external thread. The limiting plate 4 is a rectangular plate structure, and the limiting plate 4 is provided with a limiting hole 41. The utility model uses the matching design of the first stepped groove 21 and the second stepped groove 22 to wind the shell 2 into a cylindrical structure. In this step, the mutual embedding of the first stepped groove 21 and the second stepped groove 22 helps to maintain the cylindrical shape of the shell 2. After the winding of the shell 2 is completed, the electrode cap 1 is sleeved on the top of the shell 2. The circular truncated cone design of the electrode cap 1 helps it to be closely and stably installed on the shell 2. Next, the positioning ring 3 is installed at the bottom of the shell 2. Since the top of the outer wall of the positioning ring 3 is designed with external thread, and the bottom of the inner wall of the shell 2 is designed with internal thread 23, the positioning ring 3 can be stably installed on the shell 2 through threaded connection. On the outer side of the shell 2, the limiting plate 4 is placed at a suitable position. The length of the limiting plate 4 should match the distance between the electrode cap 1 and the opposite side of the positioning ring 3, so as to ensure that it can stably fix the shell 2. Then, the protrusion 211 passing through the positioning hole 221 extends into the limiting hole 41 of the limiting plate 4. Since the protrusion 211 and the limiting hole 41 are designed, they can be aligned with each other and kept stable. The last step is to fix the protrusion 211 and the limiting plate 4 together through hot melt connection. This ensures that the limiting plate 4 can be stably kept on the shell 2, thereby increasing the stability and strength of the entire electrode post structure. Through the above steps, the assembly of the lithium battery electrode post structure with a rolled edge is completed. This design not only improves the assembly efficiency and shortens the production time, but also enhances the reliability and durability of the electrode post due to the close cooperation and fixation between the components.

[0040] It will be obvious to a person skilled in the art that the utility model is not limited to the details of the exemplary embodiments described above and that the utility model can be implemented in other concrete forms without departing from the spirit or essential characteristics of the utility model. The embodiments should therefore be considered in all respects as exemplary and not restrictive, the scope of the utility model being defined by the appended claims rather than the above description, and it is therefore intended to embrace all variations falling within the meaning and range of equivalents of the elements of the claims. Any reference signs in the claims should not be considered as limiting the claims involved.
