Title:
DEVICE FOR ADJUSTING DAMPING FORCE AND HEIGHT, SEAT AND VEHICLE SUSPENSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/073650
Kind Code:
A1
Abstract:
A device (10) for adjusting damping force and height, a seat and a vehicle suspension system. The device (10) for adjusting the damping force and the height comprises an adjusting valve (A), which is respectively connected to an air source, the atmosphere, an air spring (20) and a damping force adjusting device of a damping element (40); the adjusting valve (A) comprises a first cylinder (A100) and at least one first control lever (A200) slidably arranged in the first cylinder (A100); by means of relative displacement of the first control lever (A200) and the first cylinder (A100) relative to each other, an air flow connection is generated between the air spring (20) and the air source or the atmosphere, so as to adjust the height of the air spring (20); and/or the damping force adjusting device of the damping element (40) is in air flow connection to the air source or the atmosphere, so that the damping force adjusting device of the damping element (40) is driven by air to execute a corresponding operation to control the damping element (40) to output a corresponding damping force, thereby adjusting the size of damping force of the damping element (40). Therefore, the device (10) for adjusting damping force and height adjusts the damping force and the height.
