Linkage gear mechanism for automatic opening/closing driving mechanism
First Claim
1. A linkage gear mechanism for an automatic opening/closing driving mechanism, wherein the linkage gear mechanism is integrally and concentrically provided with a worm gear driven portion, a gear driving portion and a cam linkage portion successively in the direction of its rotation central axis;
- the worm gear driven portion including worm gear engaging teeth configured to engage with a driving worm gear, the worm gear engaging teeth distributed circumferentially about an entirety of a peripheral wall of the worm gear driven portion;
the cam linkage portion including a reset groove, a recess, a transition portion and a boss successively positioned about a periphery of the cam linkage portion, the transition portion including a flat planar portion, and the boss being asymmetrical about an axis perpendicular to the rotation central axis and the axis parallel to the flat planar portion; and
the gear driving portion includes a plurality of driving teeth positioned on a portion of a peripheral wall of the gear driving portion.
