Unmanned aerial vehicle (UAV) delivery structure

1. A delivery structure for an unmanned aerial vehicle (UAV) to deliver a piece of cargo, the delivery structure comprises:

a mounting piece ( 1 ) having a mounting groove ( 11 ) arranged on the mounting piece ( 1 );

wherein an opening direction of the mounting groove ( 11 ) extends upward, and the piece of cargo ( 100 ) is hooked into the mounting groove ( 11 );

a reset assembly ( 2 ) is configured to deform under a weight of the piece of cargo ( 100 ) when the piece of cargo ( 100 ) is lifted, and resets to drive the piece of cargo ( 100 ) away from the mounting groove ( 11 ) when the piece of cargo ( 100 ) touches a ground;

a limiting piece ( 3 ) having a first end connected to the reset assembly ( 2 ) when the piece of cargo ( 100 ) is not lifted, and having a second end connected with the mounting piece ( 1 ) by magnetic adsorption to seal the opening of the mounting groove ( 11 ); and

wherein when the piece of cargo ( 100 ) is lifted, the reset assembly ( 2 ) drives the limiting piece ( 3 ) to move thereby separating the second end from the mounting piece ( 1 ).

2. The delivery structure of an UAV according to claim 1 , wherein the second end of the limiting piece ( 3 ) is provided with a first magnetic piece; a second magnetic piece is arranged on the mounting piece ( 1 ); wherein the second magnetic piece has a magnetism opposite to a magnetism of the first magnetic piece.

3. The delivery structure of an UAV according to claim 2 , wherein:

the first magnetic piece and the limiting piece ( 3 ) are detachable from each other; and/or

the second magnetic piece and the mounting part ( 1 ) are detachable from each other.

4. The delivery structure of an UAV according to claim 1 , wherein the first end of the limiting piece ( 3 ) and the reset assembly ( 3 ) are rotationally connected to each other.

5. The delivery structure of an UAV according to claim 1 , further comprising a chute ( 12 ) disposed on the mounting piece ( 1 ) and connected with the mounting groove ( 11 ); wherein the reset assembly ( 2 ) is arranged in the chute ( 12 ); and wherein the reset assembly ( 2 ) includes a connected reset piece ( 21 ) and a slide block ( 22 ), the reset piece 21 is located between the slide block ( 22 ) and a bottom of the chute ( 12 ); the slide block ( 22 ) and the chute ( 12 ) slide together and are abutted against the piece of cargo ( 100 ); and wherein the limiting piece ( 3 ) is connected with the slide block ( 22 ).

6. The delivery structure of an UAV according to claim 5 , further comprising a guide hole arranged on the slide block ( 22 ); wherein one side of the reset piece ( 21 ) is penetrated into the guide hole and abutted against a top wall of the guide hole.

7. The delivery structure of an UAV according to claim 5 , wherein the reset assembly ( 2 ) further includes a guide piece ( 23 ) arranged at the bottom of the chute ( 12 ) wherein an end of the reset piece ( 21 ) that is away from the slide block ( 22 ) is sleeved on the guide piece ( 23 ).

8. The delivery structure of an UAV according to claim 5 , wherein an upper side wall of the mounting groove ( 11 ) is further provided with an avoidance groove ( 13 ) to avoid the sliding of the slide block ( 22 ).

9. The delivery structure of an UAV according to claim 5 , further comprising:

a protrusion ( 222 ) disposed on one of 1.) a side wall of the slide block ( 22 ) and 2.) a side wall of the slide groove ( 12 );

a guide groove ( 122 ) disposed on the other of the 1.) the side wall of the slide block ( 22 ) and 2.) a side wall of the slide groove ( 12 ); and

wherein the protrusion ( 222 ) slides and fits in the guide groove ( 122 ).
