Abstract
Description
Technical Field
[0001] This utility model belongs to the field of battery element technology, and in particular relates to a positioning damping ring that is easy to assemble precisely. Background Technology
[0002] In battery modules, damping rings are commonly used to mount on the outside of battery posts, serving to reduce vibration, buffer, and insulate. Traditional damping rings are mostly one-piece structures with fixed dimensions, making it difficult to adapt to battery posts of different heights. If splicing is required, the lack of an effective positioning structure makes them prone to misalignment, loosening, or even detachment during assembly or use, affecting the safety and stability of the battery. Furthermore, the smooth inner and outer surfaces or simple structure of ordinary damping rings result in insufficient friction with the battery posts and casing, making them prone to slippage under vibration or thermal expansion and contraction, reducing damping effect and lifespan. In addition, existing splicing methods often rely on adhesives or complex snap-fit mechanisms, which are inconvenient to assemble and have poor reliability.
[0003] To address this issue, we provide a positioning damping ring that facilitates precise assembly. Utility Model Content
[0004] The purpose of this invention is to provide a positioning damping ring that facilitates precise assembly. By setting positioning holes and limiting grooves on the damping unit and using a connecting pair with trapezoidal limiting protrusions, combined with the integrated improvement of inner and outer rib structures and elastic insulating materials, high-precision alignment, reliable connection and rapid assembly between multiple damping rings are achieved. This solves the problems of assembly misalignment, loose connection, poor adaptability and insufficient damping stability that exist in existing damping rings when used in scenarios such as battery columns.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a positioning damping ring that facilitates precise assembly, comprising a combined damping ring; the combined damping ring includes at least one damping unit and a connecting pair for aligning adjacent damping units; the inner circumferential surface of the damping unit is provided with at least one axially extending inner rib, and the outer circumferential surface of the damping unit is provided with at least one axially extending outer rib; the annular end face of the damping unit is provided with positioning holes at equal intervals, and the positioning holes are provided with opposing limiting grooves in the middle; the connecting pair includes a connecting post and a limiting protrusion integrally provided at the end of the connecting post, the limiting protrusion being adapted to the limiting groove.
[0006] The present invention is further configured such that the damping unit is integrally formed from an elastic insulating material, and both the inner and outer rings of the damping unit are provided with chamfered structures.
[0007] The present invention is further configured such that the cross-sections of the inner convex rib and the outer convex rib are both semi-circular, and the inner convex rib and the outer convex rib are integrally formed on the inner and outer rings of the damping unit.
[0008] The present invention is further configured such that the cross-section of the limiting protrusion is trapezoidal, and the outer side of the limiting protrusion is pressed tightly against the inner wall of the limiting groove.
[0009] The present invention is further configured such that the connecting post passes through the positioning hole, and the periphery of the connecting post is in contact with the inner wall of the positioning hole.
[0010] The present invention is further configured such that the annular end faces of adjacent damping units are in contact with each other, and the damping units are wrapped around the outside of the battery column.
[0011] This utility model has the following beneficial effects: 1. This utility model achieves high-precision alignment and double limiting (axial fixing + circumferential anti-rotation) of adjacent damping units by setting equidistantly distributed positioning holes and opposing limiting grooves on the end face of the damping unit, and cooperating with the connecting pair with trapezoidal cross-section limiting protrusions. This effectively avoids the misalignment, offset or loosening problems that are easy to occur when traditional damping rings are combined in multiple segments, and significantly improves the assembly accuracy and structural stability.
[0012] 2. This utility model features axially extending semi-circular inner and outer ribs on the inner and outer circumferential surfaces of the damping unit. This not only enhances the friction and fit between the damping ring and the outer wall of the battery column and the outer shell, but also provides good guidance and buffering, effectively suppressing vibration transmission and improving overall damping performance. At the same time, the ribs are designed with a semi-circular cross-section, which optimizes the contact stress distribution while ensuring structural strength, avoiding material fatigue or damage caused by stress concentration, and extending service life.
[0013] 3. This utility model adopts a modular combination structure, which can flexibly adjust the height or number of segments of the damping ring according to actual needs. It can achieve rapid splicing through standardized connecting pairs without the need for adhesives, screws or other auxiliary fasteners, which simplifies the assembly process and facilitates later maintenance and replacement, significantly improving production efficiency and ease of use.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] Please see Figure 1-4 This utility model is a positioning damping ring that facilitates precise assembly, comprising a combined damping ring 100; the combined damping ring 100 includes at least one damping unit 101 and a connecting pair 102 for aligning adjacent damping units 101; the inner circumferential surface of the damping unit 101 is provided with at least one axially extending inner rib 101a, and the outer circumferential surface of the damping unit 101 is provided with at least one axially extending outer rib 101b; the annular end face of the damping unit 101 is provided with equidistant positioning holes 101c, and the positioning holes 101c are provided with opposing limiting grooves 101d in the middle; the connecting pair 102 includes a connecting post 102a and a limiting protrusion 102b integrally disposed at the end of the connecting post 102a, the limiting protrusion 102b being adapted to the limiting groove 101d.
[0022] The positioning damping ring provided in this embodiment facilitates precise assembly, enabling stable installation and reliable connection of the damping ring on cylindrical components such as battery posts. Specifically, the positioning damping ring adopts a modular structure, consisting of at least one damping unit 101 as the basic unit. Each damping unit 101 has axially extending inner and outer convex ribs 101b on its inner and outer circumferential surfaces, respectively. This not only enhances the friction and fit stability between the damping ring and the battery post but also serves as a guide and limiter during assembly, preventing circumferential slippage. Simultaneously, positioning holes 101c are equidistantly formed on the end face of the damping unit 101, and limiting grooves are provided oppositely in the center of the positioning holes 101c. 101d provides a precise assembly reference for the connecting pair 102. The connecting pair 102 consists of a connecting post 102a and an integrally formed trapezoidal cross-section limiting protrusion 102b at its end. The limiting protrusion 102b and the limiting groove 101d are geometrically and dimensionally compatible. When the connecting post 102a is inserted into the positioning hole 101c of the adjacent damping unit 101, the limiting protrusion 102b is embedded in the limiting groove 101d and pressed tightly against the groove wall, thereby achieving dual positioning in the axial and circumferential directions and effectively preventing assembly misalignment or loosening. In summary, this utility model, through the coordinated cooperation of the positioning hole 101c, the limiting groove 101d, and the connecting pair 102, combined with the rib structure and material properties, achieves high-precision alignment, rapid assembly, and long-term operational reliability of the damping ring during multi-segment splicing or overall installation.
[0023] Specifically, the limiting protrusion 102b has a trapezoidal cross-section, and the outer side of the limiting protrusion 102b is pressed tightly against the inner wall of the limiting groove 101d; the connecting post 102a passes through the positioning hole 101c, and the periphery of the connecting post 102a is in contact with the inner wall of the positioning hole 101c; the annular end faces of adjacent damping units 101 are in contact with each other, and the damping unit 101 is wrapped around the outside of the battery post.
[0024] Furthermore, the damping unit 101 is integrally molded from an elastic insulating material, and both the inner and outer rings of the damping unit 101 have chamfered structures, combining flexibility and electrical insulation properties, making it suitable for applications such as batteries where safety and stability are critical. The cross-sections of the inner rib 101a and the outer rib 101b are both semi-circular, and the inner rib 101a and the outer rib 101b are integrally molded into the inner and outer rings of the damping unit 101, which optimizes the contact stress distribution while ensuring structural strength, thereby improving the damping effect and service life.
[0025] The operation process of this embodiment is as follows: First, according to the actual application requirements, such as the outer diameter and height of the battery column, a suitable number of damping units 101 are selected. Each damping unit 101 is integrally injection molded from an elastic insulating material (such as silicone, rubber or thermoplastic elastomer). Both its inner and outer rings are provided with chamfered structures to facilitate assembly and introduction. The inner circumferential surface of the damping unit 101 is uniformly distributed with at least one semi-circular cross-section inner rib 101a along the axial direction to enhance the friction with the outer wall of the battery column and provide axial guidance. The outer circumferential surface is provided with at least one semi-circular cross-section outer rib 101b to cooperate with the outer shell or constraint structure to improve the overall stability. Subsequently, when multiple damping units 101 need to be spliced together along the axial direction, the connecting pair 102 is aligned with the corresponding positioning holes 101c on the end faces of two adjacent damping units 101 for assembly: first, the connecting post 102a is inserted into the positioning hole 101c of one of the damping units 101, then the corresponding positioning holes 101c of the adjacent damping units 101 are aligned, and the connecting post 102a is pushed in until it completely penetrates the two positioning holes 101c. During this process, the trapezoidal cross-section limiting protrusion 102b at the end of the connecting column 102a is simultaneously embedded into the opposing limiting groove 101d in the middle of the positioning holes 101c of the two damping units 101. Due to the micro-deformation of the elastic material, it forms a tight fit with the inner wall of the limiting groove 101d, thereby achieving precise positioning and reliable connection of adjacent damping units 101 in both the circumferential and axial directions, preventing relative rotation or axial movement. After the connecting pair 102 is assembled, the assembled combined damping ring 100 is fitted onto the outside of the battery column. The inner rib 101a achieves tight coverage through elastic deformation, while the outer rib 101b can form auxiliary limiting with the inner wall of the battery compartment or other structures, further improving assembly stability. The entire assembly process requires no additional fasteners or adhesive processes, is simple to operate, has precise positioning, and is easy to disassemble and assemble. It is suitable for battery modules, electronic devices, or vibration damping scenarios with high requirements for assembly efficiency and reliability.
