Description

Technical Field

[0001] This utility model belongs to the technical field of air spring dust cover, specifically an air spring dust cover exhaust structure. Background Technology

[0002] Since recent years, with the improvement of people's living standards, cars have entered ordinary households and are no longer a luxury. With the popularization of cars, people's requirements are also getting higher and higher. Car door noises and difficult opening and closing have become increasingly important issues.

[0003] An automotive air spring is a type of spring that operates using compressed air. Its design and construction incorporate several special components to ensure its performance and safety. Among these, the dust cover is a crucial component. This dust cover is typically a flexible shield that encloses the air spring, primarily serving to prevent the accumulation of dust and debris and to reduce the risk of leakage caused by environmental factors.

[0004] Existing air spring dust covers have certain drawbacks. During use, excess compressed air inside the air spring assembly needs to be expelled. If the dust cover's exhaust volume is insufficient, it may affect the performance of other internal components. Furthermore, the dust cover is prone to twisting and deformation, reducing its service life. During packaging and transportation, dust or impurities can easily enter the dust cover and affect the performance of the air spring assembly, failing to meet people's needs. Utility Model Content

When the air spring is working, there will be compressed air flowing inside it. If dust and debris in the external environment directly contact the internal components of the air spring, it may affect its normal operation, or even cause wear or blockage. Therefore, the presence of the dust cover can effectively prevent these external impurities from contacting the key components of the air spring, thereby keeping them clean and in good working condition. The dust cover not only prevents external impurities from entering, but also reduces the risk of leakage caused by environmental factors to a certain extent. By covering the key parts of the air spring, the dust cover can reduce the impact of external factors such as moisture and dust on the sealing performance, thereby maintaining the air spring's sealing and stability. The dust cover can protect the main internal working components from external environmental damage, ensuring that they maintain good performance even in extreme or complex working environments.

[0007] As a further embodiment of this utility model: the upper end of the dust cover body is provided with an interface for press-fitting the connector assembly. The connection between the connector assembly and the dust cover body is sealed by applying adhesive.

[0008] As a further embodiment of this utility model: the dust cover body is composed of a retractable foldable cover and a support cover opening integrally formed with the foldable cover, and the interface is set on the support cover opening and is formed by punching.

[0009] As a further embodiment of this utility model: the connector assembly includes a fixed end fixedly connected to the support cover opening and an external end integrally formed with the fixed end and sealed with the connecting cover; wherein, the fixed end and the external end are inclinedly connected, and the connector assembly is used in conjunction with the dust cover body to effectively discharge excess air pressure in the air spring assembly system and prevent the dust cover body from deforming.

[0010] As a further embodiment of this utility model: the fixed end has a structure that is smaller on the outside and larger on the inside, and the outer end away from the fixed end has a circular ring structure. The outer wall of the outer end is provided with a retaining arc member that engages with the connecting cover. The retaining arc member can be used in conjunction with the retaining element.

[0011] As a further embodiment of this utility model: the outer upper side of the connecting cover is provided with several sets of protrusions in a circular array that fit against the inner side of the card. The connecting cover can effectively protect the connector assembly and prevent impurities from entering the interior of the dust cover body during packaging and transportation.

[0012] As a further embodiment of this utility model: the card has a "U" shaped structure, and the lower end of the card is provided with an inwardly recessed snap-fit ​​part, which is connected to the card arc member.

[0013] As a further embodiment of this utility model: the dust cover body is made of TPV material, and the connector assembly and connecting cover are both made of PA66-GF30 material.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) This utility model, through the setting of the dust cover body and the exhaust mechanism, the dust cover body and the connector assembly are used together to effectively discharge the excess air pressure in the air spring assembly system and prevent the dust cover from deforming. The dust cover body and the connector assembly are connected together by gluing and pressing. The production process is simple and firm, reducing the welding process and saving costs.
