[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] With the rapid development of the automobile industry, air springs are used more and more widely in automobiles. Air springs are composed of an air tank body, pipelines, and air springs. A whistling sound will be produced when the air tank inflates the air spring. The pipeline and the base are combined into an anti-loosening structure, and the pipeline and the base need to be pulled outward to lock them. At this time, a gap will be generated between the end of the pipeline and the base. When the airflow passes through the gap, the airway is not smooth, causing the gas flow to produce a whistling sound.

[0032] Reference below Figure 1-Figure 3 An air tank assembly for an air spring according to an embodiment of the utility model is described.

[0033] According to the utility model, the air tank assembly 1 for the air spring includes an air tank body 11, a base, a pipeline 14 and a sealing member 15. The air tank body 11 is provided with a first interface 111; the base is provided on the air tank body 11 and installed on the first interface 111, and an installation channel connected with the first interface 111 is formed on the base; one end of the pipeline 14 is accommodated in the installation channel and connected with the first interface 111, the pipeline 14 can move relative to the base, and a gap 141 is formed between the end of the pipeline 14 and the base; the sealing member 15 can be deformably arranged in the gap 141.

[0034] Specifically, the base is installed on the gas tank body 11, and a first interface 111 is provided on the gas tank body 11. A mounting channel connected to the first interface 111 is formed on the base. The gas in the gas tank body 11 flows out from the first interface 111 and flows into the mounting channel. One end of the pipeline 14 is inserted into the base and accommodated in the mounting channel. The gas can flow into the pipeline 14 through the first interface 111. When the pipeline 14 cooperates with the base, it moves relative to the base. When the pipeline 14 moves, a gap 141 is formed between the end of the pipeline 14 and the base. At this time, when the gas flows out from the first interface and flows through the gap 141, the airflow is filled with The gap 141 flows out in multiple directions, resulting in an uneven airway and a whistling sound produced by the gas flow. Therefore, the present application solves the problem of uneven airway by setting a seal 15 to fill the gap 141, wherein the seal 15 can be set at one end of the pipeline 14, and when the pipeline 14 is inserted into the installation channel, the pipeline 14 compresses the seal 15 to stop with the base, and the seal 15 is compressed and deformed. When the pipeline 14 moves relative to the base, the seal 15 rebounds and fills the gap 141 between the pipeline 14 and the base, and the airflow flows into the pipeline from the first interface through the seal, thereby ensuring that the airflow channel is smooth and avoiding the airflow from producing a whistling sound.

[0035] According to the utility model, the air storage tank assembly 1 for the air spring is provided with a seal 15 between the pipeline 14 and the base. When the pipeline 14 enters the base, the seal 15 is compressed by the pipeline 14 to stop with the base. When the pipeline 14 moves relative to the base, the seal 15 rebounds and fills the gap 141 between the pipeline 14 and the base, and the gap 141 is sealed to ensure that the airflow flows directly from the air storage tank body 11 into the pipeline 14, and the airway of the airflow is smooth, thereby avoiding the airflow from producing a whistling sound.

After the seal 15 is deformed, it fills the space between the end face of the pipeline 14 and the base. Since the seal 15 is constructed as an annular or arc-shaped hollow structure, the first interface 111 and the second interface remain connected, and the gas in the gas tank body 11 can flow into the second interface through the first interface 111. By constructing the seal 15 as an annular or arc-shaped structure, the seal 15 can fill the gap 141 after deformation. The seal 15 can ensure gas circulation and will not affect the gas circulation.

[0038] According to some embodiments of the utility model, a first anti-loosening portion located in the installation channel is formed on the base, and a second anti-loosening portion cooperating with the first anti-loosening portion is formed on the outer surface of the pipeline 14. The first anti-loosening portion and the second anti-loosening portion are suitable for limiting the pipeline 14 from escaping from the installation channel.

[0039] Specifically, after the pipeline 14 is inserted into the base, the pipeline 14 can move along the installation channel to form a gap 141 between the end of the pipeline 14 and the base. During the movement of the pipeline 14, the second anti-loosening portion on the outer surface of the pipeline 14 and the first anti-loosening portion in the installation channel can cooperate through a snap-fit ​​form to limit the pipeline 14 from detaching from the installation channel, wherein the first anti-loosening portion can be constructed as a snap-fit ​​groove, and the second anti-loosening portion can be constructed as a snap-fit ​​protrusion. The pipeline 14 moves until the snap-fit ​​protrusion enters the snap-fit ​​groove, and the pipeline 14 is snap-fitted with the base to limit the pipeline 14 from detaching from the base.

[0040] According to some embodiments of the utility model, the base includes a base body 12 and a joint 13, the base body 12 is arranged on the gas tank body 11 and fixed to the gas tank body 11, and the inner wall of the base body 12 is formed with a first channel; at least a part of the joint 13 is accommodated in the first channel and a second channel is formed in the joint 13, the pipeline 14 is accommodated in the second channel, and the joint 13 is detachably connected to the base body 12; wherein the first channel and the second channel jointly define an installation channel.

[0041] Specifically, the base body 12 and the joint 13 can be connected by threaded cooperation, a first channel is formed in the base body 12, and a second channel is formed in the joint 13, and the first channel and the second channel jointly define an installation channel, wherein the base body 12 is fixedly connected to the gas tank body 11, the first interface 111 is communicated with the installation channel, and one end of the pipeline 14 passes through the second channel and the first channel in sequence and is communicated with the first interface 111, wherein the joint 13 and the base body 12 are detachably connected, the joint 13 and the base body 12 jointly support the pipeline 14, the pipeline 14 is stably installed, and when the pipeline 14 leaks or is damaged, the base body 12 and the joint 13 body can be disassembled to facilitate the replacement of the pipeline 14.

[0043] Specifically, the first limiting portion can be constructed as a snap-in groove, and the second limiting portion can be constructed as a snap-in protrusion. In the direction in which the pipeline 14 is separated from the installation channel, as the pipeline 14 moves relative to the installation channel, the snap-in protrusion enters the snap-in groove and stops against the inner wall of the snap-in groove. With the cooperation of the snap-in groove and the snap-in protrusion, the pipeline 14 cannot be separated from the installation pipeline 14. The joint 13 and the base body 12 respectively limit the pipeline 14 to prevent the pipeline 14 from being separated from the installation channel and ensure stable inflation.
