Aerial vehicle
Disclosed is an aerial vehicle, comprising: an airframe, a propeller(s), a duct(s) and a driving device, wherein the duct(s) is arranged on the airframe and adapted to increase a lifting force for the aerial vehicle, the propeller is arranged in the respective duct and is connected to the airframe, and the driving device is connected to the propeller(s) and is arranged on the airframe.
1. An aerial vehicle comprising,
an airframe, a propeller(s), a duct(s) and a driving device, wherein the duct(s) is arranged on the airframe and adapted to increase a lifting force for the aerial vehicle, the propeller is arranged in the respective duct and is connected to the airframe, and the driving device is connected to the propeller(s) and is arranged on the airframe,
wherein the airframe comprises a main frame, the duct comprises a cylindrical duct housing which is arranged on the periphery of the main frame, and an interior space is enclosed by the duct housing,
wherein the aerial vehicle further comprises a damping device adapted to damp an impact resulted from a rotation of the propeller(s), and
the damping device comprises a damping support and an elastic member, wherein the damping support is connected to the main frame through the elastic member, and a PCB of the aerial vehicle is arranged on the damping support,
wherein the elastic member is a rubber ball,
the duct comprises a cylinder portion and an outward-extending portion, and an opening of the outward-extending portion is larger than that of the cylinder portion,
a motor mounting is arranged in the duct and is connected to an inner wall of the duct through a brace, and the motor is arranged in the motor mounting and is connected to the propeller,
the aerial vehicle further comprises a base to which the duct(s) is connected,
wherein an upper shield is arranged above the base,
wherein a pedestal(s) is arranged on the base and a main control board is fixed on the pedestal(s), and a damping washer is arranged on the pedestal for supporting the upper shield.
2. The aerial vehicle of claim 1 , wherein the aerial vehicle further comprises a blade protection cover(s) arranged on the respective duct housing.
3. The aerial vehicle of claim 2 , wherein an outward extending flange is arranged on an edge of the duct housing and is provided with a plurality of engaging taps; and
the blade protection cover is provided with engaging grooves which are adapted to engage with the engaging taps to fix the blade protection cover onto the duct housing.
4. The aerial vehicle of claim 1 , wherein the aerial vehicle further comprises an analog camera arranged on the damping support.
5. The aerial vehicle of claim 1 , wherein the aerial vehicle further comprises an undercarriage arranged on the airframe.
6. The aerial vehicle of claim 1 , wherein the driving device comprises a motor and a chargeable battery electrically connected with each other, wherein an output shaft of the motor is connected to the propeller, and the battery and the motor are arranged on the airframe.
7. The aerial vehicle of claim 1 , wherein the outward-extending portion has a horn shape.
8. The aerial vehicle of claim 1 , wherein the motor mounting extends beyond the duct and serves as a taking-off/landing support.
9. The aerial vehicle of claim 1 , wherein there are four ducts.
10. The aerial vehicle of claim 1 , wherein the duct, the brace, the motor mounting and the base are integrally formed.
11. The aerial vehicle of claim 1 , wherein connecting posts for fixing the upper shield are arranged at two ends of the base and are adapted to pass through the upper shield.
