Abstract

Integration driving mechanism for fin control assembly applied for UAV, aerial observation equipment, comprises: the control assembly, the fin root assembly, the fin shaft. The control assembly is small size, high temperature operation, waterproof ability, vibration resistance, easily replacement and reparation that is still warrant the operation condition.

First claim

The invention claimed is:

1. An integration driving mechanism for a fin control assembly comprising:
a control assembly forming a driving mechanism base integrated with a fin root assembly by screws;
the fin root assembly providing a base to integrate a main cylinder and a fin shaft;
a fin having an aerodynamic shape to drive the flying equipment;
a fin shaft assembly for transforming force from the control assembly to the fin; and
a coupling used to connect a force transmission system and the fin shaft assembly, wherein:
the control assembly is structured to include the force transmission system, a cover system and a control system, wherein:
the force transmission system includes a motor, a first spur gear, a second spur gear, a third spur gear, a fourth spur gear, a fifth spur gear, a sixth spur gear, a first bevel gear shaft, a second bevel gear shaft, and a plurality of bearings;
the cover system includes a first cover, a second cover, a third cover, a fourth cover, a fifth cover, a sixth cover, a first screw, a second screw, and a cable gland connector;
the control system includes a sensor shaft, a rotary sensor, and a control circuit board;
the covers of the cover system are made from steel alloy, aluminum alloy, plastic or composite and comprise reference holes or pins on the covers;
the cover system is designed with bearing hubs, the covers are assembled together by screws;
wires pass through the cable gland connector to provide waterproof features;
the force transmission system comprises gears that are made of steel alloy or aluminum alloy;
the number of gears depends on a load requirement;
the gears are designed as spur, helical, spiral or bevel gears; and
the gears are integrated with the shafts by keys, the shafts are assembled on the covers by bearings.

2. The integration driving mechanism for the fin control assembly according to claim 1 wherein:
the fin root assembly is made from steel alloy or aluminum alloy that has an aerodynamic shape and a hole in the middle to assemble the fin shaft.

3. The integration driving mechanism for the fin control assembly according to claim 1 wherein:
the fin is made from steel alloy, aluminum alloy, plastic, composite that has an aerodynamic shape.

4. The integration driving mechanism for the fin control assembly according to claim 1 wherein:
the fin shaft assembly is made from steel alloy, or aluminum alloy that has a cylinder shape, the fin shaft assembly includes the fin shaft and bearings.

5. The integration driving mechanism for the fin control assembly according to claim 1 wherein a heat isolation layer is provided to protect the control system assembly.

6. The integration driving mechanism for the fin control assembly according to claim 1 wherein:
the coupling is made from steel alloy, aluminum alloy, or a combination of steel and aluminum alloy shaped based on operation conditions.

7. The integration driving mechanism for the fin control assembly according to claim 6 , wherein the coupling comprises a splined shaft.
