Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 4, a shock-absorbing airbag for a truck seat includes an upper cover plate 1 and a lower cover plate 2, the upper cover plate 1 and the outer side of the lower cover plate 2 are fastened and connected by an airbag skin 3, an inflation space 4 is formed between the inside of the airbag skin 3 and the upper cover plate 1 and the lower cover plate 2, the upper cover plate 1 is provided with an air inlet 11, and the air inlet 11 inflates or exhausts air to expand or contract the airbag skin 3, so that the upper cover plate 1 and the lower cover plate 2 are relatively far away from or close to each other.

In addition, the outer side of the air bag skin 3 is sleeved with an upper fixing ring 5 and a lower fixing ring 6, and the two ends of the air bag skin 3 are pressed on the outer walls of the upper cover plate 1 and the lower cover plate 2 by the upper fixing ring 5 and the lower fixing ring 6.

In addition, the circumferential directions of the upper cover plate 1 and the lower cover plate 2 are provided with concave tooth structures 7 along the axial direction, and the air bag skin 3 is pressed on the tooth structures 7 through the upper fixing ring 5 and the lower fixing ring 6 to prevent the air bag skin 1 from falling off. The tooth-shaped structure increases the friction force between the air bag skin and the upper cover plate 1 and the lower cover plate 2, and the air bag skin is tightly pressed by the upper fixing ring 5 and the lower fixing ring 6, so that the air bag skin is ensured not to be separated in the processes of repeated inflation and deflation.

In addition, the air bag cover 1 is of a circular ring columnar structure, and the upper end of the air bag cover 1 is pressed on the tooth-shaped structure 7 through the upper fixing ring 5 after being turned inwards.

In addition, the upper end of the upper cover plate 1 is a conical surface structure 12 with a diameter reducing inwards, and the upper end part of the air bag skin 3 is attached to the conical surface structure 12.

In addition, the bottom of the lower cover plate 2 extends along the radial direction to form a step-shaped structure 21, and the bottom of the air bag skin 3 is abutted against the step-shaped structure 21.

In addition, the upper part of the upper cover plate 1 is provided with a groove body 13 which is obliquely arranged along the radial direction, and the air inlet 11 is arranged at the rear end part of the groove body 13.

In addition, the tooth-like structure 7 includes a plurality of inverted teeth 71 arranged at regular intervals.

Further, the tooth width of the inverted tooth 71 is 1mm, the pitch is 0.5mm, the inverted tooth angle is 45 °, and the number of teeth is 5.

The concrete working principle of the damping air bag of the truck seat is as follows: the upper end face of the upper cover plate 1 is fixed on a truck seat frame, air is inflated through the air inlet 11, the air bag skin 3 pushes the lower cover plate to move along the axial direction 2 (as shown by an arrow in figure 1) due to inflation, the lower cover plate 2 is far away from the upper cover plate 1 until the inflation is finished, and at the moment, the damping air bag is in a fully-inflated state. Then the inflation port 11 is exhausted, the air bag skin 3 contracts, and the lower cover plate 2 returns to the initial position.

Compared with the prior art, the damping air bag of the truck seat can improve abnormal sound of the initial inflation state of the truck seat, and has the advantages of compact product structure, small actual occupied space, good stability and high strength.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
