Description

Technical Field

[0001] This utility model relates to the field of vibration reduction technology for automotive air supply units, and in particular to a vibration reduction device with a locking structure. Background Technology

[0002] With the rapid development of the automotive industry, the basic function of automobiles—meeting transportation needs—is no longer sufficient to meet people's growing lifestyle demands. Air suspension systems, which enhance comfort, are gradually becoming essential components in vehicles. As the source of the suspension's air supply, the air supply unit is receiving increasing attention, and the damping components connected to the vehicle body within this unit are key factors affecting its performance.

[0003] Currently, the vibration reduction of the gas supply unit consists of vibration damping pads and metal brackets, such as Figure 1 As shown, Figure 1 The vibration damping pads are made of rubber, and the two metal brackets are interference-fitted with the damping pads. During assembly, the compressibility of the damping pads is used to align the two metal brackets, providing a certain locking force. This prevents problems when the entire air supply unit is immediately assembled to the vehicle body. However, in actual production and delivery, after long-term transportation or storage in a warehouse, the locking force may decrease, causing the metal brackets to detach. This leads to a series of problems, including rework by workers and increased costs.

[0004] For example, utility model application CN202421916529.3 discloses a vibration isolation component, an air supply unit, and a vehicle. Using this solution, the first and second limiting parts create a limiting structure to prevent the secondary suspension bracket from detaching from the connection surface of the secondary suspension, thereby improving the stability of the connection between the secondary suspension bracket and the secondary suspension. However, this solution involves setting barbed anti-detachment blocks on the secondary suspension and anti-detachment grooves on the bracket to form a limiting structure, preventing the bracket from detaching from the connection surface, resulting in high process complexity. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a vibration damping device with a locking structure, thereby solving the problem that the metal bracket and vibration damping pad in the air supply unit may detach due to reduced locking force caused by long-term transportation or storage.

[0006] The purpose of this utility model can be achieved through the following technical solution: a vibration damping device with a locking structure, including a vibration damping pad, an upper metal bracket and a lower metal bracket, wherein the upper metal bracket and the lower metal bracket have a flexible snap-fit ​​device, and the two metal brackets are flexibly snapped together and then pressurized with the vibration damping pad to form vibration damping.

[0007] As a further embodiment of this utility model, the flexible snap-fit ​​device includes a rubber ring, which is connected to the end of the upper metal bracket, and the inner ring of the end of the lower metal bracket is provided with an annular groove that matches the rubber ring.

[0008] As a further embodiment of this utility model, the upper metal bracket has a snap-fit ​​hole at its end, and the inner wall of the rubber ring has a protrusion that matches the snap-fit ​​hole. The rubber ring snaps into the snap-fit ​​hole through the protrusion.

[0009] As a further embodiment of this utility model, the outer ring of the lower metal bracket is configured as a bulge, and the inner ring of the vibration damping pad has a groove in the middle, with the bulge matching the groove.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model constructs a double-locking mechanism by setting a flexible snap-fit ​​device between the upper and lower metal supports, combined with the interference fit between the groove of the inner ring of the vibration damping pad and the outer bulge of the metal support. This structure ensures that after the two metal supports are assembled by compression, they are locked in a locked state whether through the internal flexible snap-fit ​​or the fit between the outer bulge and the groove, effectively solving the problem of metal supports falling off due to the weakening of locking force caused by long-term transportation or storage in traditional vibration damping structures. While ensuring connection stability, the structure is simpler, assembly is more convenient, significantly improving product reliability and reducing costs caused by rework.

[0012] 2. This invention utilizes a flexible snap-fit ​​device to transform the traditional rigid connection between metal parts into a partially flexible connection. When the rubber ring is engaged in the annular groove of the lower metal bracket, its elastic properties not only act as a buffer, preventing rigid collisions between the metal brackets, but also absorb and attenuate vibration energy during equipment operation. This flexible connection method directly improves the vibration isolation performance of the entire damping device, enabling the air supply unit equipped with this damping structure to more effectively isolate vibration transmission during vehicle operation, thereby improving the comfort of the vehicle's air suspension system. Simultaneously, the buffering effect of the rubber ring also protects the metal bracket connection points, extending their service life.

[0013] 3. The flexible snap-fit ​​structure of this utility model has good fault tolerance and can compensate for minor installation errors that may exist between the upper and lower metal brackets. The connection between the rubber ring and the snap-fit ​​hole (through the convex bulge structure and its cooperation with the annular groove) makes the assembly process smoother and reduces the reliance on precision assembly tools. This design not only simplifies the assembly steps and improves production efficiency, but also helps to ensure the consistency of product quality. Attached Figure Description

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Example 1:

[0026] This embodiment discloses a vibration reduction method with a locking structure, such as... Figure 2 and Figure 3 As shown, it includes a vibration damping pad 100, an upper metal bracket 200 and a lower metal bracket 300. The upper metal bracket 200 and the lower metal bracket 300 are connected by a flexible snap-fit ​​device. After the two metal brackets are flexibly snapped together, they are interference-fitted with the vibration damping pad 100 to form vibration damping.

[0027] The vibration damping pad 100 is made of rubber. An arc-shaped groove 110 is provided in the middle of the inner ring of the vibration damping pad 100. After the two metal brackets are flexibly snapped together, an arc-shaped bulge 320 is formed on the outer side of the joint. The arc-shaped bulge 320 and the arc-shaped groove 110 match each other. After assembly, the interference fit between the arc-shaped bulge 320 and the arc-shaped groove 110 is used to realize the interference fit between the two metal brackets and the vibration damping pad 100 after the two metal brackets are flexibly snapped together, thus forming vibration damping.

[0028] The upper metal bracket 200 and the lower metal bracket 300 are connected by a flexible snap-fit ​​device. Based on the flexible snap-fit ​​device, when the upper metal bracket 200 and the lower metal bracket 300 are aligned and squeezed together on the vibration damping pad 100, they are locked in a locked state both inside and out, thus preventing the metal brackets from falling off. The flexible snap-fit ​​device changes the original hard connection between the two metal brackets into a partially soft connection, which also improves the vibration isolation performance.

[0029] Example 2:

[0030] Based on Example 1, this example optimizes the structure of the flexible snap-fit ​​device, specifically, as follows: Figure 4 As shown, the flexible snap-fit ​​device includes a rubber ring 400, which is connected to the end of the upper metal bracket 200. The inner ring of the end of the lower metal bracket 300 is provided with an annular groove 310 that matches the rubber ring 400.

[0031] In this application, the ends of the upper metal bracket 200 and the lower metal bracket 300 are the ends that are close to each other when the two metal brackets are installed.

[0032] The connection method between the rubber ring 400 and the end of the upper metal bracket 200 can be as follows: Figure 5 The connection structure shown features a snap-fit ​​hole 210 at the end of the upper metal bracket 200. The inner wall of the rubber ring 400 has a protrusion 410 that matches the snap-fit ​​hole 210. The rubber ring 400 snaps into the snap-fit ​​hole 210 via the protrusion 410, achieving a stable connection between the rubber ring 400 and the end of the upper metal bracket 200. This connection method ensures the connection strength between the rubber ring 400 and the upper metal bracket 200. During assembly, simply align the protrusion 410 of the rubber ring 400 with the snap-fit ​​hole 210 at the end of the upper metal bracket 200 to complete the assembly.

[0033] Furthermore, such as Figure 4 and Figure 6 As shown, the lower metal bracket 300 has an annular groove 310 at the inner end of the lower metal bracket 300 to match the rubber ring 400. When the upper metal bracket 200 and the lower metal bracket 300 are spliced, the outer side of the rubber ring 400 is engaged in the annular groove 310, realizing the flexible engagement of the two metal brackets. This engagement method is not only easy to operate, but also effectively enhances the stability of the connection.

[0034] Once the rubber ring 400 is engaged in the annular groove 310, its elastic properties allow it to fit tightly against the inner wall of the groove, forming a reliable seal and connection. During equipment operation, even under vibration or external impact, the rubber ring 400 acts as a buffer and damper, preventing rigid collisions between the upper metal support 200 and the lower metal support 300, further improving the vibration isolation performance of the entire vibration damping device. Simultaneously, the flexible connection of the rubber ring 400 can also compensate for potential installation errors between the upper metal support 200 and the lower metal support 300 to a certain extent, making the assembly process smoother and improving production efficiency and product quality.

[0035] Furthermore, such as Figure 6 As shown, the outer ring of the lower metal bracket 300 is set as a bulge 320, and the inner ring of the damping pad 100 is provided with a corresponding groove 110. The bulge 320 matches the groove 110. During assembly, the upper and lower metal brackets are flexibly snapped together by the interference fit between the bulge 320 and the groove 110, and together with the damping pad 100, they form a damping effect.

[0036] Based on the above structure, the upper and lower metal brackets are aligned and pressed together in the vibration damping pad 100, and are locked both inside and out, thus preventing the metal brackets from falling off. The rubber ring 400 on the upper metal bracket 200 changes the original hard connection of the upper and lower metal brackets 300 into a partially soft connection, which also improves the vibration isolation performance.

[0037] The principle of this invention: This invention transforms the traditional rigid connection into a partially flexible connection through a flexible snap-fit ​​device, effectively improving vibration isolation performance while ensuring the metal bracket is locked and prevented from falling off. This structure, combined with the interference fit between the arc-shaped groove 110 of the inner ring of the vibration damping pad 100 and the bulge 320 formed on the outer side of the metal bracket, ensures that the upper and lower metal brackets 300 are locked in a locked state both inside and out after compression assembly, thus preventing detachment. The flexible connection made of rubber not only provides cushioning and vibration damping, avoiding rigid collisions between metals, but also compensates for installation errors, thereby optimizing both structural stability and vibration isolation performance.
