Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical technology, specifically to a flanged terminal post and its battery cover. Background Technology
[0002] Currently, the existing riveted pole cover plates on the market rely entirely on the contact between the expanded part and the step of the riveting block to achieve their supporting function after the riveting and expansion process.
[0003] This structure causes forces to concentrate at the step, resulting in a relatively low limit of the top force it can withstand, which has an adverse impact on the development of high-performance battery cover plates. Utility Model Content
[0004] The first objective of this invention is to address the aforementioned problems in existing technologies by providing a flanged pole with high stability.
[0005] The second objective of this invention is to provide a battery cover plate employing the aforementioned flanged terminal post.
[0006] To achieve the first objective, this utility model can be implemented through the following technical solutions:
[0007] A flanged pole includes a cylindrical body, a disc-shaped base plate at the lower end of the body, and an annular recessed groove at the upper end of the body, forming a cylindrical connecting section at the upper end of the body. The outer diameters of the connecting section, the body, and the base plate increase sequentially. The connecting section has an annular flange protruding outward at its upper end, and an annular recessed deformation groove at its upper end, the deformation groove being close to the flange.
[0008] In the aforementioned flanged pole, the cross-section of the deformation groove is arc-shaped.
[0009] In the aforementioned flanged pole, the distance between the outer wall of the deformation groove and the outer side of the connecting section is A, and the thickness of the flange is B, with dimension A being greater than dimension B.
[0010] In the aforementioned flanged pole, dimension A is 2 to 4 times the size of dimension B.
[0011] In the aforementioned flanged pole, the width of the deformation groove is the same as dimension A.
[0012] In the aforementioned flanged pole, the connecting section, body, base plate, and flange are all integral structures.
[0013] In the aforementioned flanged pole, the outer side of the connecting section has a raised edge extending from the flange to its middle portion.
[0014] In the aforementioned flanged pole, the flange is located at the upper part of the upper end of the connecting section.
[0015] In the aforementioned flanged pole, the thickness of the flange is 0.5-2mm.
[0016] To achieve the second objective, this utility model can be implemented through the following technical solutions:
[0017] A battery cover, characterized in that it comprises a substrate, a lower plastic, an upper plastic, a riveting block, and a flanged terminal post. The lower plastic is fixed to the lower part of the substrate, the riveting block is connected to the upper part of the substrate, and the flanged terminal post is inserted and connected to the lower plastic, the substrate, and the riveting block. The upper plastic is pressed tightly between the riveting block and the substrate. The upper end of the riveting block has a recessed positioning groove. The flange of the flanged terminal post is fastened to the upper part of the riveting block and the flange is embedded in the positioning groove. The inner edge of the riveting block is pressed tightly between the protruding edge and the flange.
[0018] Compared with the prior art, this flanged pole has a flange at its upper end. Therefore, the flange, together with the convex edge on the connecting section, enables the pole body and the riveting block to have at least two contact surfaces. When subjected to top force, it can disperse the top force, thereby increasing its top force limit and effectively improving its stability.
[0019] Since the flanging is formed by press riveting, the deformation groove can stably form the flanging. The flanging is not easily damaged during the preparation process and has a high forming rate, which has high practical value. Attached Figure Description

[0026] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.
[0027] like Figure 1-4 As shown, this flanged pole includes a cylindrical body 1, a disc-shaped base plate 2 at the lower end of the body 1, and an annular recessed groove at the upper end of the body 1, forming a cylindrical connecting section 3 at the upper end of the body 1. The outer diameters of the connecting section 3, the body 1, and the base plate 2 increase sequentially. The upper end of the connecting section 3 has an annularly protruding flange 4, and the upper end of the connecting section 3 also has an annularly recessed deformation groove 5, which is close to the flange 4.
[0028] The above structure shows the shape after the flanged terminal is installed in the battery cover. When the flanged terminal is not installed in the battery cover, the flange 4 is cylindrical and does not protrude outward from the connecting section 3 in a ring shape.
[0029] Under the action of the riveting equipment, the cylindrical flange 4 gradually deforms and eventually transforms from a cylindrical structure into a disc-shaped structure. That is, after the transformation, the flange 4 eventually protrudes out of the outer side of the connecting section 3 in an annular shape.
[0030] The riveting equipment is a commercially purchased component; therefore, its specific technical features will not be described in detail in this embodiment. In this embodiment, the JH8-500H hydraulic riveting machine sold by Changzhou Lingxie Intelligent Equipment Co., Ltd. is used.
[0031] Since the deformation groove 5 at the upper end of the connecting segment 3 is adjacent to the flange 4, more stable forming can be achieved during the shape transformation of the flange 4. Specifically, the strength of the connecting segment 3 near the flange 4 is appropriately reduced, which helps the flange 4 to complete the shape transformation stably.
[0032] The cross-section of the deformation groove 5 is arc-shaped.
[0033] This improves its structural compactness.
[0034] The distance between the outer wall of the deformation groove 5 and the outer side of the connecting section is A, and the thickness of the flange is B. Size A is greater than size B.
[0035] The ratio of size A to size B only appropriately reduces the strength at the deformation point of flange 4, ensuring the strength of the entire pole while guaranteeing the stable forming of flange 4.
[0036] In this embodiment, dimension A is twice the size of dimension B. However, depending on the actual situation, it is also feasible for dimension A to be four times the size of dimension B.
[0037] The width of the deformation groove 5 is the same as that of dimension A.
[0038] The connecting section 3, body 1, base plate 2, and flange 4 are all integral structures. This effectively improves the structural stability of the entire pole post. Depending on the actual situation, it is also feasible to fix the base plate 2 and body 1 into a whole by means of copper-aluminum composite (that is, the base plate and body are two different materials, and the two different materials are stably connected after copper-aluminum composite treatment). Using copper-aluminum composite can reduce the cost of the pole post, thereby reducing the production cost of the entire cover plate.
[0039] The outer side of the connecting segment 3 has a raised edge 31 extending from the flange 4 to its middle portion.
[0040] After the flanged pole is connected to the rivet block 9, the protruding edge 31 and the rivet block 9 will form a stable connection position.
[0041] The flange 4 is located at the upper part of the upper end of the connecting section 3.
[0042] During the riveting process, the flange 4 can be stably stressed, preventing the riveting equipment from acting on the connecting section 3.
[0043] The thickness of the flange 4 is 0.5mm. However, depending on the specific circumstances, a thickness of 2mm for the flange 4 is also feasible.
[0044] The thickness of the flange 4, within this dimensional range, ensures stable deformation after riveting while maintaining sufficient strength. Of course, strength can be further increased through welding, thereby raising the upper limit of the pole's top force. The welding method used is existing technology; in this embodiment, laser penetration welding is employed.
[0045] This battery cover includes a substrate 6, a lower plastic 7, an upper plastic 8, a rivet block 9, and a flanged terminal post. The lower plastic 7 is fixed to the lower part of the substrate 6, the rivet block 9 is connected to the upper part of the substrate 6, and the flanged terminal post is inserted and connected to the lower plastic 7, the substrate 6, and the rivet block 9. The upper plastic 8 is pressed tightly between the rivet block 9 and the substrate 6, and the flange 4 of the flanged terminal post is fastened to the upper part of the rivet block 9. The inner edge of the rivet block 9 is pressed tightly between the protrusion 31 and the flange 4.
[0046] The upper end of the main body 1 presses against the lower part of the rivet block 9, the protruding edge 31 presses against the middle part of the rivet block 9, and the flange 4 presses against the upper part of the rivet block 9.
[0047] It can be seen that the above structure enables the pole body and the riveting block 9 to have at least two contact surfaces, which can disperse the top force when subjected to top force, thereby increasing the top force limit that it can withstand and effectively improving its stability.
[0048] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
[0049] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
