Abstract

This disclosure provides a drone propeller assembly, comprising a pair of base plates, a plurality of internally threaded cylinders, a plurality of bolts, and a plurality of blades. The internally threaded cylinders are disposed between the base plates, with one end of each cylinder connected to one of the base plates. Bolts are screwed onto each internally threaded cylinder, and the other end of each cylinder is screwed onto a corresponding bolt, which passes through another base plate to secure the base plates together. Blades are configured corresponding to each internally threaded cylinder, with one end of each blade clamped between the base plates and having a through hole that engages with a corresponding internally threaded cylinder.

Claims

1. A drone propeller assembly, comprising: a pair of base plates; a plurality of internally threaded cylinders disposed between the pair of base plates, wherein one end of each internally threaded cylinder is connected to one of the base plates; a plurality of bolts respectively threaded onto each of the internally threaded cylinders, wherein the other end of each internally threaded cylinder is threaded onto a corresponding bolt and the bolt passes through another base plate to lock the pair of base plates together; and a plurality of blades respectively configured corresponding to each of the internally threaded cylinders, wherein one end of each blade is clamped between the pair of base plates and has a through hole, and the through hole is fitted onto the corresponding internally threaded cylinder.

2. The UAV propeller assembly as described in claim 1, wherein the mounting plate includes a base plate and a top plate, the internally threaded cylinders are respectively connected to the base plate, and the bolts respectively pass through the top plate.

3. The UAV propeller assembly as described in claim 2, wherein a boss is provided on one side of the base plate, and the boss has a shaft hole penetrating the base plate and a plurality of locking holes penetrating the base plate.

4. The UAV propeller assembly as described in claim 3, wherein the boss is disposed between the mounting plates.

5. The UAV propeller assembly as described in claim 3, wherein a mounting window is provided on the top plate at the position corresponding to the boss, penetrating the top plate.

6. The UAV propeller assembly as described in claim 2, wherein the base plate is made of aluminum alloy or titanium alloy.

7. The UAV propeller assembly as claimed in claim 1, wherein an annular arc surface is provided at the connection between any of the base plates and each of the internally threaded cylinders connected to the base plate.

8. The UAV propeller assembly as claimed in claim 1, wherein an annular semicircular groove is provided at the connection between any of the base plates and each of the internally threaded cylinders connected to the base plate.

9. The UAV propeller assembly as claimed in claim 2, wherein an annular semicircular groove is provided at the connection between the base plate and each of the internally threaded cylinders connected to the base plate.

10. The UAV propeller assembly as claimed in claim 1, wherein in each blade, a washer is attached to each of the two sides of the blade to abut against each of the seat plates that hold the blade, and each washer is fitted with a corresponding internal threaded cylinder.
