Title:
ONE-WAY DAMPING STRUCTURE AND ADJUSTING ASSEMBLY COMPRISING ONE-WAY DAMPING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2021/082541
Kind Code:
A1
Abstract:
A one-way damping structure (1), comprising a spring (11), a drive element (12) and a friction force generation member, the spring (11) and the drive element (12) being connected such that the spring (11) is driven by means of the drive element (12); the spring (11) comprises a fixing portion (111), a connecting portion (112) and an annular portion (113), the connecting portion (112) being located between the fixing portion (111) and the annular portion (113) and connecting the fixing portion (111) to the annular portion (113), and the fixing portion (111) being fixed; and the annular portion (113) comprises at least half a ring of a defining spring hole which spirally extends in the circumferential direction, and slides relative to the friction force generation member so as to generate friction torque. Also disclosed is an adjusting assembly which comprises the described one-way damping structure (1). A seat height adjuster utilizes one-way damping properties in which the spring (11) of the one-way damping structure (1) generates different torques in different rotation directions; moreover, in combination with a traditional output structure (2) and an installation structure (3), a driver (4) may continue to stably overcome a fixed load so as to work when a seat moves downward under a load, while not affecting the lifting force of adjusting the seat upwards.
