Abstract

The invention discloses a more reliable seat suspension mechanism, composed of a lower frame, a rigidity adjustment device and an upper frame, wherein the rigidity adjustment device is located between the lower frame and the upper frame; the rigidity adjustment device is composed of an inner support, an outer support, two springs, a damper and a rigidity adjustment assembly; the upper frame is composed of a front side frame, a rear side frame, a left side frame and a right side frame; the inner support and the outer support compose an interior shear-type mechanism; the rigidity adjustment assembly is composed of a pull rod, a lever, a body box and an adjustment screw; the lever is located in the body box, the adjustment screw penetrates through the body box and the lever, the lever is connected with the adjustment screw via a nut, and the fulcrum of the lever is hinged together with the body box, and the other end of the lever is hinged with a pull rod; one end of each of the two springs is hooked at two ends of the pull rod, and the other end of each of the two springs is hooked on a cross rod; the end part of the adjustment screw exposes out of the upper frame; and the damper is slantwise arranged between the lower frame and the upper frame. The more reliable seat suspension mechanism disclosed by the invention has a sufficient suspension amount and no sway phenomenon.

Description

technical field [0001] The invention relates to a vehicle seat, in particular to a more reliable seat suspension mechanism. Background technique [0002] In the truck seat, the suspension mechanism is an important functional structure on the seat, which can reduce the damage caused by vibration to the occupants in the harsh driving environment. With the development of my country's automobile industry and the increasing popularity of automobile sales, end customers have begun to pay attention to the comfort of seats, and more and more attention has been paid to the comfort of seats. At present, in the domestic suspension field, there is a single type, which is the combination of fork-shaped structure and slider. This combination has high requirements on production level and material performance. If the corresponding requirements are not met, the seat will cause serious shaking problems. The existing suspension seat has insufficient suspension capacity and severe shaking. C...
