In addition, the height control valve for the low suspension travel seat has the advantages of simple structure, convenience in installation, stable operation and low cost.
Further, as shown in FIG. 4, two sealing rings are arranged on the inner wall of the valve chamber 411, a first air flow cavity 411-1 and a second air flow cavity 411-2 are spaced in the valve chamber 411, the valve rod 420 slides in the valve chamber 411 for different distances, the first groove 421 is communicated with the first air flow cavity 411-1 and the second air flow cavity 411-2 across the first sealing ring 411-5 to control air inflation of the air bag, and the first groove 421 is communicated with the second air flow cavity 411-2 and the outside across the second sealing ring 411-6 to control air deflation of the air bag. It should be noted that, the way of separating the first air flow chamber and the second air flow chamber in the valve chamber by providing the sealing ring is only one implementation means, and other ways of separating the first air flow chamber and the second air flow chamber in the valve chamber are all within the protection scope of the present application.
Further, as also shown in fig. 5, the two axial ends of the first groove 421 are respectively provided with a second groove 422, the first groove 421 communicates with the second groove 422, and the width of the second groove 422 is smaller than the width of the first groove 421.
When the height of the low suspension travel seat is at the levitation height, both the first groove 421 and the second groove 422 are located in the first air flow chamber 411-1, at which time the air bag is neither inflated nor deflated.
When the second groove 422 located at the lower portion of the first groove 421 crosses the first seal ring 411-5, a minute amount of gas enters the air bag through the second groove 422, the height of the low suspension travel seat rises by a small extent, and when the second groove 422 located at the upper portion of the first groove 421 crosses the second seal ring 411-6, a minute amount of gas is discharged to the atmosphere through the second groove 422, and the height of the low suspension travel seat decreases by a small extent.
When the first groove 421 spans the first seal 411-5, more gas enters the airbag through the first groove 421, the height of the low suspension travel seat increases by a larger extent, and when the first groove 421 spans the second seal 411-6, more gas is discharged to the atmosphere through the second groove 422, the height of the low suspension travel seat decreases by a larger extent.
It can be seen that the comfort is further improved by providing the first groove 421 and the second groove 422 such that the suspension adjustment amplitude is gradually changed.
Further, the first groove 421 includes a rectangular groove and a V-shaped groove which are communicated with each other, the V-shaped groove being provided at both axial ends of the rectangular groove. The first groove 421 may have a rectangular shape in the middle and triangular shapes at both ends.
When the height of the low suspension travel seat is at the levitation height, the entire structure of the first groove 421 is located in the first air flow chamber 411-1, and at this time, the air bag is neither inflated nor exhausted.
When the V-shaped groove at the lower part of the second groove 422 crosses the first seal ring 411-5, a trace amount of gas enters the airbag through the second groove 422, the height of the low suspension travel seat rises by a small extent, and when the V-shaped groove at the upper part of the second groove 422 crosses the second seal ring 411-6, the trace amount of gas is discharged to the atmosphere through the second groove 422, and the height of the low suspension travel seat decreases by a small extent.
When the rectangular groove of the first groove 421 spans the first seal ring 411-5, more gas enters the airbag through the first groove 421, the height of the low suspension travel seat is raised by a larger extent, and when the rectangular groove of the first groove 421 spans the second seal ring 411-6, more gas is discharged to the atmosphere through the second groove 422, the height of the low suspension travel seat is lowered by a larger extent.
It can be seen that the comfort is further improved by providing the shape of the first groove 421 such that the suspension adjustment amplitude is gradually changed.
Of course, in order to prevent the occurrence of bottoming of the low suspension travel seat, the number of the first grooves 421 may be increased, and the depth of the first grooves 421 may be changed. The present application is not further limited in the number and depth of the first grooves 421. Meanwhile, in order to meet the suspension adjustment requirements of different low suspension travel seats, the number of the second grooves 422 can be increased, the depth of the second grooves 422 can be changed, and the number and the depth of the second grooves 422 are not further limited.
In summary, the application not only can realize the adjustment of the suspension height range of the low suspension travel seat by changing the positions, the numbers and the depths of the first grooves and the second grooves, but also can realize the adjustment of the suspension height range of the low suspension travel seat by setting the shape and the depth of the first grooves.
