Disclosed is a one-way damping structure, comprising a spring, a drive element and a friction force generation member, the spring and the drive element being connected such that the spring is driven by means of the drive element; the spring comprises a fixing portion, a connecting portion and an annular portion, the connecting portion being located between the fixing portion and the annular portion and connecting the fixing portion to the annular portion, and the fixing portion being fixed; and the annular portion comprises at least half a turn for defining a spring opening 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 and a seat height adjuster utilizing one-way damping properties in which the spring of the one-way damping structure generates different torques in different rotation directions.
A one-way damping structure, comprising a spring, a drive element and a friction force generation member, wherein the spring and the drive element are connected such that the spring is driven by means of the drive element, wherein the spring comprises a fixing portion, a connecting portion and an annular portion, wherein the connecting portion is located between the fixing portion and the annular portion and connects the fixing portion to the annular portion, wherein the fixing portion is fixed, wherein the annular portion comprises at least half a turn spirally extending in a circumferential direction and defining a spring opening, and wherein the annular portion slides relative to the friction force generation member so as to generate a friction torque, wherein the one-way damping structure further comprises a bushing structure connected to the drive element in an anti-torsion manner, wherein the fixing portion is clamped by the bushing structure, wherein the annular portion is tightly installed in a fixing groove, an inner cylindrical surface of which is formed as the friction force generation member, and wherein the friction torque is generated by the slide of an outer diameter surface of the annular portion relative to the inner cylindrical surface of the fixing groove.
An adjustment assembly comprising a one-way damping structure, comprising a spring, a drive element and a friction force generation member, wherein the spring and the drive element are connected such that the spring is driven by means of the drive element, wherein the spring comprises a fixing portion, a connecting portion and an annular portion, wherein the connecting portion is located between the fixing portion and the annular portion and connects the fixing portion to the annular portion, wherein the fixing portion is fixed, wherein the annular portion comprises at least half a turn spirally extending in a circumferential direction and defining a spring opening, wherein the annular portion slides relative to the friction force generation member so as to generate a friction torque, and wherein the adjusting assembly further comprises an installation structure and a driver, wherein the one-way damping structure is installed on the installation structure, wherein the driver has a motor shaft, wherein the annular portion of the spring is around on the motor shaft in an interference fit manner such that the friction torque is generated by the slide of an internal wall defining the opening of the annular portion relative to an outer surface of the motor shaft.
