Description

A High-Profile Suspension Integrated Air Shock Absorbing Seat

technical field

The invention relates to a high-profile suspended integrated air damping seat.

Background technique

The types of truck seats in the market are becoming more and more complete. The high-profile and suspended integrated seat can greatly simplify the mechanism and at the same time simplify the operation of the occupants. However, the integrated seats in the market now adjust the height of the seat by adjusting the relative relationship of the control terminals, which will cause the adjustment to lag behind the adjustment action. At the same time, the structure of this type of seat is relatively complicated.

Contents of the invention

The purpose of the present invention is to provide a high profile suspension integrated air shock absorbing seat.

The present invention is composed of a base, an upper seat, an inner hinge bracket, an outer hinge bracket, an air bag, a holding mechanism, a compressed air source, a control mechanism and a damper. The inner hinge bracket and the outer hinge bracket are hinged together by an intermediate shaft, and the outer hinge bracket The upper end of the bracket is hinged to the upper seat through the upper shaft, the inner hinge bracket is hinged to the base through the lower shaft, the upper end of the inner hinge bracket is slid in the upper seat, and the lower end of the outer hinge bracket is slid in the base;

The lower end of the air bag is fixed on the base, and the section where the intermediate shaft of the inner hinge bracket is hinged with the base is fixed with a support plate, and the upper end of the air bag rests on the bottom surface of the support plate. For the lifting of the bracket, the compressed air source communicates with the air bag through a pipeline and the control mechanism, the compressed air source directly communicates with the air bag through another pipeline, and the hinge damper is connected between the inner hinge bracket above the intermediate shaft and the base;

The holding mechanism is composed of a cylinder, a wedge, a brake, a tension spring, and a holding shaft. The holding shaft is movably fitted on one end of the intermediate shaft. The holding shaft and the intermediate shaft can rotate relatively, and the holding brake is wrapped in On the outer circumference of the holding shaft, a tension spring is arranged at the opening end of the holding brake, and the tension spring holds the holding brake tightly. A brake opening block is arranged on the inner side of the upper and lower parts of the opening end of the holding brake, and the wedge block is slidably arranged between the two opening blocks. There are baffles on both sides of the opening end of the gate to prevent the wedge-shaped block from sliding out from both sides, the other end of the wedge-shaped block is fixedly connected with the telescopic rod of the cylinder, one end of the cylinder is fixed on the upper seat, and the cylinder communicates with the compressed air source through the pipeline;

The control mechanism is composed of a control air valve, a cam and a pipeline. The compressed air source communicates with the air bag through the pipeline and the control mechanism. The control air valve is arranged on the outer hinge bracket. The two valve stems are respectively the inlet valve stem and the outlet valve stem. The cam is movably sleeved on the intermediate shaft, and is fixed together with the inner hinge bracket through a tightening mechanism. The cam extends with two wheel arms, and the ends of the two wheel arms The end has opposite slopes, and the slopes at the ends of the two wheel arms are respectively in contact with the two valve stems of the control air valve.

Working process of the present invention:

High-profile function: When the cylinder of the holding mechanism drives the wedge block to retract, the wedge block will open the opening end of the brake, and the brake will open. At the same time, the air bag is directly inflated/deflated. At this time, the height of the suspension changes and the height of the seat changes, which will cause the clamping shaft and the cam of the control mechanism to rotate with the lowering of the upper seat. When the adjustment is completed, the clamping mechanism will Hug to death again.

Suspension function: The cam and the inner hinge bracket are fixed together by the holding mechanism. When the suspension mechanism floats up and down, the cam will alternately contact with the two valve stems on the outer hinge bracket, so as to realize the inflation/deflation of the air bag. Realize the suspension function.

Beneficial effects of the present invention:

1. The seat damping mechanism and the height adjustment mechanism are integrated, which greatly simplifies the complexity of the mechanism.

2. The present invention can realize stepless height adjustment, which can be adjusted to any height position according to different occupants.

3. The present invention can reliably realize release and locking between mechanisms by tightening the mechanism.

4. In the present invention, the air source is directly connected to the air bag during the working process through the control mechanism, and the adjustment accuracy is higher.

5. The structure of the adjusting end of the present invention is simple, and the user interface is greatly simplified through button adjustment.
