Abstract

The present invention discloses an unmanned aerial vehicle and a battery thereof. The battery includes a battery body and a shell disposed on one end of the battery body. The shell has a clamp button disposed on the side opposite the unmanned aerial vehicle. One end of the clamp button is fixed on the shell and the other is used for detachably connecting with the unmanned aerial vehicle. The clamp button makes the battery detachably connect with the main body of the unmanned aerial vehicle be possible and it is very convenient for changing the battery.

First claim

What is claimed is:

1. A multi-rotor unmanned aerial vehicle, comprising:
a main body comprising a battery compartment;
four arms, wherein each arm is coupled to the main body;
a propulsion assembly disposed on the each arm, wherein the propulsion assembly comprises a propeller and a motor, the motor being configured to drive the propeller to rotate in order to generate lift force;
a battery accommodated in the battery compartment, and the battery comprising a shell and a battery body disposed in the shell;
a clamp button disposed on the shell, wherein one end of the clamp button is mounted on the shell and the other end of the clamp button is detachably coupled to the main body; and
a restorable elastic piece disposed on an inner side of the clamp button;
wherein one end of the restorable elastic piece is disposed on the shell and the other end of the restorable elastic piece is fixed with the clamp button:
wherein the battery compartment comprises a clamping portion configured to detachably connect to the clamp button;
wherein the clamp button is configured to cause the restorable elastic piece to be pressed down in a first state where the battery is not completely pushed into the battery compartment or is only partially positioned in the battery compartment;
wherein in a second state where the batter is completely pushed or positioned into the battery compartment, the restorable elastic piece is configured to automatically rebound so that (a) the clamp button is able to return back to its original place and (b) the battery is able to be stuck by the cooperation of the clamping portion and the clamp button.

2. The multi-rotor unmanned aerial vehicle according to claim 1 , wherein the unmanned aerial vehicle comprises at least two clamp buttons.

3. The multi-rotor unmanned aerial vehicle according to claim 2 , wherein the number of the clamping portion is the same as that of the clamp buttons.

4. The multi-rotor unmanned aerial vehicle according to the claim 2 , wherein the at least two clamp buttons are disposed on opposite sides of the shell.

5. The multi-rotor unmanned aerial vehicle according to claim 1 , wherein a hook is disposed on the end of the clamp button for detachably hanging on the unmanned aerial vehicle.

6. The multi-rotor unmanned aerial vehicle according to the claim 5 , wherein the clamp button comprises a body and the hook is disposed on one end of the body on the clamp bottom.

7. The multi-rotor unmanned aerial vehicle according to the claim 6 , wherein a groove is formed between the body on the clamp button and the hook.

8. The multi-rotor unmanned aerial vehicle according to claim 6 , wherein an anti-slip structure is configured on an outer surface of the body of the clamp button.

9. The multi-rotor unmanned aerial vehicle according to claim 8 , wherein the anti-slip structure is a wave shape convex structure.

10. The multi-rotor unmanned aerial vehicle according to claim 1 , wherein the unmanned aerial vehicle comprises at least two restorable elastic pieces, the at least two restorable elastic pieces are mirror symmetric.

11. The multi-rotor unmanned aerial vehicle according to claim 1 , wherein the shape of the restorable elastic piece is S-shape.

12. The multi-rotor unmanned aerial vehicle according to claim 1 , wherein the number of the restorable elastic piece is the same as that of the clamp button.
