FLOCKED SPRING
Document Type and Number:
WIPO Patent Application WO/2019/137068
Kind Code:
A1
Abstract:
A flocked spring, comprising a spring body (1), an anti-rust coating, and a flocked coating (2) on the outer surface of the spring. The anti-rust coating is provided on the surface of the spring body, and the flocked coating (2) on the outer surface of the spring is provided on an outer layer of the anti-rust coating. The outer surface of the spring is flocked and the side surface is avoided from flocking, so that the longitudinal solid height of the spring is reduced, an electric tailgate system with a small space can also use the flocked spring, and the problem of noise is solved. A circular steel wire is replaced with an oval or goose-egg-shaped steel wire (3), so that the longitudinal solid height of the spring is reduced. An electrophoretic coating (4) is replaced with a zinc aluminum micro-sheet coating (7), so that the anti-rust capability is improved, and environmental pollution is reduced.
