Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to a gas storage tank body with a stable pressure gas supply characteristic. Background Art

[0002] With technological advancements in the automotive and transportation sector, people are increasingly demanding greater comfort and safety features. Seats with lumbar adjustment, massage devices, and active side wing systems have emerged to address this need. These effectively address the back fatigue often associated with long driving periods, as well as the poor lateral support provided by seats without active side wing systems during sharp turns.

[0003] Among them, the air tank is an essential component in the above-mentioned pneumatic adjustment system. It stores air by compressing the internal air to supply gas to realize the pneumatic adjustment function of the vehicle seat.

[0004] In related technologies, since traditional gas storage tank manufacturing processes mostly use blow molding or metal material tank bodies, they can basically be regarded as a rigid shell. The external dimensions are fixed by the mold and cannot be changed after molding. They take up a large space during use, and their inconvenience in use is becoming increasingly prominent. Summary of the Invention

[0005] In order to solve some or all of the above technical problems, the present application provides a gas storage tank body with a stable pressure gas supply characteristic.

[0007] Furthermore, an elastomer is provided between the gas tank carrier and the internally stored gas. When gas is stored in the internally stored gas, the internal pressure of the internally stored gas increases, and the elastomer is squeezed by the internally stored gas to store elastic force. When the internally stored gas is supplied to the outside, the internal pressure of the internally stored gas decreases, and the elastomer releases the elastic force to squeeze the internally stored gas. The elastomer is used to assist in compensating the pressure of the internally stored gas, thereby ensuring that the gas will be released from the internally stored gas at a stable pressure.

[0008] Furthermore, the tubular carrier is configured as a soft carrier tube, one end of the soft carrier tube is connected to a sealing structure, and the other end is connected to the airflow connector.

[0009] Furthermore, the tubular carrier is configured as a soft serrated tube, and a plurality of connecting ribs are integrally formed on the outer peripheral wall of the soft serrated tube along its own length direction. The plurality of connecting ribs are circumferentially distributed along the outer peripheral wall of the soft serrated tube. One end of the soft serrated tube is connected to a sealing structure, and the other end is connected to the airflow connector.

[0012] Furthermore, the soft elastic gas storage gas is configured as a soft gas storage tube, which has the function of expansion and contraction. When the soft gas storage tube is in a natural state without storing gas, the diameter of the soft gas storage tube at the widest position is smaller than the diameter of the tubular carrier at the narrowest position.

[0013] Furthermore, when the tubular carrier is configured as a common cylindrical structure, the airflow connector is configured as a sealing plug, one end of which is inserted into the tubular carrier and interference fits with the tubular carrier, and the other end is provided with an air nozzle, and the soft elastic gas storage gas is connected to the air nozzle.

[0014] Further, when the tubular carrier is configured as a cylindrical structure with an outward flange, the airflow connector is configured to include: a connecting sleeve and a locking sleeve, the locking sleeve is inserted into the connecting sleeve, and an axial gap is provided between the locking sleeve and the connecting sleeve for the locking sleeve to move axially along the connecting sleeve; at least two spring claws that can be radially elastically deformed and are used to be clamped in the corresponding outer circumferential grooves of the soft bellows are circumferentially provided on the outside of the locking sleeve; mounting grooves for radially elastic deformation of the spring claws are provided at positions corresponding to each of the spring claws on the outer wall of the connecting sleeve, and the spring claws are confined in the mounting grooves; an air nozzle is also provided at the end of the connecting sleeve, and the soft elastic gas storage gas is connected to the air nozzle.

[0018] As can be seen from the above technical solution, in the gas storage tank body of the present invention, when storing gas, gas is inflated into the soft elastic gas storage, and the soft elastic gas storage expands until it reaches a full state, and the gas is compressed and stored in the soft elastic gas storage. The tubular carrier also constrains the soft elastic gas storage to prevent it from over-expanding; when supplying gas to the outside, based on the elastic self-contraction function of the soft elastic gas storage, the gas will be released from the soft elastic gas storage at a stable pressure, thereby achieving gas supply to the gas-consuming component at a stable pressure; In addition, the gas tank body described in the present invention also has the following advantages: 1. Shape-adaptive: its external dimensions will not be fixed by the mold; 2. Flexible arrangement: it can be bent at any angle according to the required shape and arranged in the vehicle seat, making the arrangement more flexible and convenient; 3.
