Title:
DAMPER DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/129604
Kind Code:
A1
Abstract:
A damper device, comprising driving gears (1, 3). The driving gears (1, 3) comprise first sector gears (11, 31) and circumferential flange portions (12, 32); the first sector gears (11, 31) comprise first tooth members (111, 112, 311, 312) and second tooth members (113, 313); the first tooth members (311, 312) comprise profile sections (3a2) and first tooth profile sections (3a3); the first tooth profile sections (3a3) smoothly transition to the circumferential flange portions (32) through the profile sections (3a2); and the distance from the profile sections (3a2) to the center of the driving gear (3) gradually decreases in the direction toward the first sector gear (31). When dampers (400, 500) need to be opened, driven gears (2, 4) can rotate under the reaction force of a damper plate to release the elastic potential energy stored by the deformation of the plate, and because the distance from buffer parts (1a, 3a) to the center of the driving gear (3) is gradually reduced, the elastic potential can be continuously released until complete release, thereby reducing the reversion of the gear pushed by the damper plate and eliminating abnormal noise when opening the damper.
