A first connection portion is disposed on one of the body and the wing. A second connection portion is disposed on the other of the body and the wing. The first connection portion and the second connection portion are detachably connected. The first connection portion is engaged with the second connection portion. The body and the wing are locked by rotating or sliding the second connection portion. The body can be conveniently assembled with or disassembled from the wing and the connection part meets the reliability of strength and rigidity and does not affect the flight performance. ## Claims ### Claim 1 An unmanned aerial vehicle, comprising a body and wings, a first connection portion is disposed on one of the body and the wing and a second connection portion is disposed on the other of the body and the wing, the first connection portion and the second connection portion being detachably connected; and the first connection portion is engaged with the second connection portion and the body and the wing are locked by rotating or sliding the second connect portion, wherein the first connection portion comprises a latch member and a protrusion disposed on the latch member, a cross-sectional width of the protrusion being greater than a cross-sectional width of the latch member; and the second connection portion comprises a locking member, wherein a guide groove for sliding of the latch member and a mounting groove for clamp fit with the protrusion are provided on the locking member, the guide groove being in communication with the mounting groove and a width of the guide groove being less than the cross-sectional width of the latch member. ### Claim 2 (depends on 1) The unmanned aerial vehicle according to claim 1, wherein the protrusion is spherical. ### Claim 3 (depends on 1) The unmanned aerial vehicle according to claim 1, wherein a first electrical connector is disposed on the body and a second electrical connector in pluggable fit with the first electrical connector is disposed on the wing. ### Claim 4 (depends on 1) The unmanned aerial vehicle according to claim 1, wherein a support member is disposed on one of the body and the wing and a clamping groove in clamp fit with the support member is disposed on the other of the body and the wing. ### Claim 5 (depends on 4) The unmanned aerial vehicle according to claim 4, wherein the support member is tubular and a cross section of the support member is rectangular. ### Claim 6 (depends on 4) The unmanned aerial vehicle according to claim 4, wherein there are two first connection portions and two second connection portions, wherein the two first connection portions are respectively disposed on two sides of the support member and the two second connection portions are respectively disposed on two sides of the support member. ### Claim 7 (depends on 1) The unmanned aerial vehicle according to claim 1, wherein the first connection portion is disposed on the body and the second connection portion is disposed on the wing. ### Claim 8 (depends on 7) The unmanned aerial vehicle according to claim 7, wherein a sliding groove is provided on the wing and the locking member is a sliding block slidably mounted in the sliding groove. ### Claim 9 (depends on 8) The unmanned aerial vehicle according to claim 8, wherein the second connection portion further comprises an elastic member disposed in the sliding groove, one end of the elastic member abutting against an inner side of the sliding groove and the other end of the elastic member abutting against the locking member. ### Claim 10 (depends on 7) The unmanned aerial vehicle according to claim 7, wherein a through hole is provided on the wing, the locking member is rotatably mounted in the through hole and a mounting hole adapted to the mounting groove is provided on a side wall of the through hole. ### Claim 11 (depends on 10) The unmanned aerial vehicle according to claim 10, wherein the locking member is cylindrical. ### Claim 12 (depends on 10) The unmanned aerial vehicle according to claim 10, wherein the second connection portion further comprises a first limiting member disposed on the locking member and a second limiting member that matches the first limiting member to limit a rotation range of the locking member is disposed in the through hole. ### Claim 13 (depends on 10) The unmanned aerial vehicle according to claim 10, wherein the second connection portion further comprises a pressing block disposed at an end of the through hole to prevent the locking member from moving out of the through hole. ### Claim 14 (depends on 10) The unmanned aerial vehicle according to claim 10, wherein the wing comprises a wing body and a connecting bracket mounted on the wing body, the through hole being disposed on the connecting bracket.
