The electric swiveling mechanism further comprises a first swiveling mechanism and a second swiveling mechanism for controlling yaw and pitch swiveling, respectively.
Claims20
An electric swiveling mechanism for two axes, comprising:
- a first swiveling mechanism, comprising:
- a base attachment for fixing said whole electric swiveling mechanism on a base;
- a first yaw gear and a second yaw gear on the same shaft, wherein the diameter of said first yaw gear is greater than said second yaw gear;
- a third yaw gear, engaging at said second yaw gear;
- and
- a yaw driving motor on said base attachment, wherein a worm gear on the shaft of said yaw driving motor is used to drive said first yaw gear, said second yaw gear, and said third yaw gear consequently;
- and
- a second swiveling mechanism, comprising:
- a pitch driving motor;
- a pitch shaft rod, wherein the both ends of said pitch shaft rod comprising a plurality of panel attachment structures for fixing to a panel;
- a tilt shaft rod, wherein said tilt shaft rod comprising a tilt gear for engaging at a worm gear on the driving shaft of said pitch driving motor 150 and a tilt worm gear for engaging at a pitch gear on said pitch shaft rod;
- a empty cylinder bearing structure for carrying a gear set supporting structure, wherein said bearing structure can be fixed and rotated on said base attachment, said bearing structure further comprising a bearing gear underneath engaging to said third yaw gear, said gear set supporting structure is vertically fixed to the internal empty space of said bearing structure, a vertical wall of said gear set supporting structure further comprising:
- a first shaft hole for the shaft of said pitch driving motor;
- a second shaft hole, located above said first shaft hole, for said pitch shaft rod;
- and
- a first tilt shaft rod fulcrum and a second tilt shaft rod fulcrum for supporting the tilt shaft rod.
