Unmanned aerial vehicle propeller assembly
First Claim
1. An unmanned aerial vehicle comprising:
- a motor assembly rotatable about a rotation axis, the motor assembly including;
a motor cap defining apertures; and
a propeller hub assembly removably engageable with the motor assembly, the propeller hub assembly including;
a retainer configured and dimensioned for engagement with the motor cap such that rotation of the motor assembly causes corresponding rotation of the propeller hub assembly, the retainer including a bridge member connecting a pair of deflectable arms resiliently repositionable between a first position, wherein the arms are positioned for engagement with the apertures respectively, in the motor cap, and a second position, wherein the arms are positioned for disengagement with the apertures in the motor cap such that the retainer can be removed from the motor assembly, the arms being movable inwardly towards the rotation axis from the first position to the second position upon application of an external force and movable outwardly away from the rotation axis from the second position to the first position upon removal of the external force; and
a hub member defining a recess configured and dimensioned to receive the bridge member of the retainer such that rotation of the retainer via engagement with the motor cap causes corresponding rotation of the hub member.

Abstract
Various embodiments of an unmanned aerial vehicle are disclosed. In some embodiments, the UAV includes a motor assembly rotatable about a rotation axis and a propeller hub assembly removably engageable with the motor assembly. The propeller hub assembly includes a retainer configured and dimensioned for engagement with the motor assembly such that rotation of the motor assembly causes corresponding rotation of the propeller hub assembly. The retainer includes a pair of deflectable arms resiliently repositionable between a first position and a second position, for engagement and disengagement with the motor assembly, respectively. The arms are movable inwardly towards the rotation axis from the first position to the second position upon application of an external force and movable outwardly away from the rotation axis from the second position to the first position upon removal of the external force.

9. A propeller hub assembly for use with an unmanned aerial vehicle including a motor assembly, the propeller hub assembly comprising:
-
a retainer configured and dimensioned for engagement with the motor assembly such that rotation of the motor assembly causes corresponding rotation of the propeller hub assembly, the retainer including a bridge member extending between a pair of deflectable arms resiliently repositionable between a first position, wherein the arms are positioned for engagement with the motor assembly, and a second position, wherein the arms are positioned for disengagement with the motor assembly such that the retainer can be removed from the motor assembly, the arms being deflectable towards one another during movement from the first position to the second position upon application of an external force to the arms and movable away from one another during movement from the second position to the first position upon removal of the external force; and a hub member defining a recess configured and dimensioned to receive the bridge member of the retainer such that rotation of the retainer via engagement with the motor assembly causes corresponding rotation of the hub member. - View Dependent Claims (10, 11, 12, 13)

14. A propeller hub assembly for use with an unmanned aerial vehicle including a motor assembly, the propeller hub assembly comprising:
-
a hub member including shoulders extending from an interior surface toward a rotation axis of the motor assembly and propellers extending from an exterior surface away from the rotation axis, and a latch member including disengagement members resiliently repositionable between a first position, wherein the disengagement members are positioned to secure the hub member to the motor assembly, and a second position, wherein the disengagement members are positioned such that the hub member can be removed from the motor assembly, wherein the disengagement members are movable towards one another during movement from the first position to the second position upon application of an external force to the disengagement members and movable away from one another during movement from the second position to the first position upon removal of the external force, and wherein the disengagement members define receiving spaces in which the shoulders of the hub member are positioned respectively, to secure the hub member to the motor assembly. - View Dependent Claims (15, 16)
