Abstract

A linkage turbine for an automatic opening/closing driving mechanism, wherein the linkage turbine is integrally and concentrically provided with a turbine driven portion, a gear driving portion and a cam linkage portion successively in the direction of the rotation central axis thereof; turbine teeth fitted with a driving turbine are provided on the whole peripheral wall of the turbine driven portion; a reset groove, a recess, a transition portion and a boss are successively provided on the periphery of the cam linkage portion; and a plurality of driving teeth are provided on part of the peripheral wall of the gear driving portion.

Claims

1. A linkage turbine for an automatic opening/closing driving mechanism, wherein the linkage turbine is integrally and concentrically provided with a turbine driven portion, a gear driving portion and a cam linkage portion successively in the direction of its rotation central axis;

turbine teeth fitted with a driving turbine are provided on the whole peripheral wall of the turbine driven portion;

a reset groove, a recess, a transition portion and a boss are successively provided on the periphery of the cam linkage portion; and

a plurality of driving teeth are provided on part of the peripheral wall of the gear driving portion.

2. The linkage turbine for an automatic opening/closing driving mechanism according to claim 1, wherein a plurality of driving teeth are provided on a part of the peripheral wall of the gear driving portion abutting the boss of the cam linkage portion.

3. The linkage turbine for an automatic opening/closing driving mechanism according to claim 1, wherein the plurality of driving teeth and the boss of the cam linkage portion are substantially the same in terms of their positions on respective peripheral walls, and central angles and lengths of arcs covered by them.

4. The linkage turbine for an automatic opening/closing driving mechanism according to claim 1, wherein peripheral rims of the recess and the boss are concentric arcs with different radiuses, the peripheral rim of the boss having a radius greater than that of the peripheral rim of the recess;

and one end of the peripheral rim of the transition portion connected to the recess is straight, while the other end thereof connected to the boss is curved.

5. The linkage turbine for an automatic opening/closing driving mechanism according to claim 4, wherein the reset groove is recessed toward the tangential direction of the peripheral rim of the recess.

6. The linkage turbine for an automatic opening/closing driving mechanism according to claim 1, wherein an inductive magnet that synchronously rotates with the linkage turbine is further provided on the linkage turbine.
