DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See attached Figures 1 to 6A folding wing UAV comprises a UAV body 1, a wing fixing base 2 and a first wing connecting rod 3; a storage groove 10 with a top opening is provided on the UAV body 1, a first fixing portion 11 is also provided on the UAV body 1, a fixing groove 110 is provided on the first fixing portion 11, the wing fixing base 2 is installed in the storage groove 10, a vertically arranged lifting slide bar 20 is also provided on the wing fixing base 2, a first end of the first wing connecting rod 3 is sleeved on the lifting slide bar 20, and a rotor a is installed on the second end of the first wing connecting rod 3; the first wing connecting rod 3 can be lifted and lowered along the lifting slide bar 20 and rotated around the lifting slide bar 20 as the axis, and the first wing connecting rod 3 can be buckled in the fixing groove 110; the first wing connecting rod 3 has a first state of being matched and connected with the first fixing portion 11, and a second state of being separated from the first fixing portion 11 and moved to the storage groove 10 for storage.

[0030] In the present invention, the first wing connecting rod 3 and the first fixing part 11 can also be fixedly connected by bolts. Specifically, in an embodiment of the present invention, the fixing groove 110 is open on the side of the first fixing part 11, so that the fixing groove 110 is a "U"-shaped structure with a side opening. Under normal conditions, the first wing connecting rod 3 is buckled in the fixing groove 110, and at this time, the first fixing part 11 also plays a role in supporting the first wing connecting rod 3. When the folding wing UAV is not needed, the first wing connecting rod 3 can be disengaged from the fixing groove 110 by external force, and then the first wing connecting rod 3 is swung to the top of the storage groove 10 with the lifting slide bar 20 as the axis, and then slides down along the lifting slide bar 20 into the storage groove 10, so as to fold and store the first wing connecting rod 3, reduce the space occupancy rate of the first wing connecting rod 3, and effectively reduce the occupied space of the folding wing UAV. Through the vertically arranged lifting slide bar 20, the first wing connecting rod 3 can be lowered into the storage groove 10 for storage or lifted out of the storage groove 10 for use. In combination with the "U"-shaped fixing groove 110 with a side opening, the structural stability of the folding wing UAV can be effectively improved. It should be noted that in the present invention, a limiting boss 200 is also provided on the top of the lifting slide bar 20. When the first wing connecting rod 3 is buckled into the fixing groove 110, the first wing connecting rod 3 also abuts against the limiting boss 200. The notch size of the fixing groove 110 is slightly smaller than the rod body size of the first wing connecting rod 3, so that the first wing connecting rod 3 needs to enter the fixing groove 110 in a snap-fitting manner, thereby further improving the connection stability between the first wing connecting rod 3 and the first fixing portion 11.

[0031] Furthermore, in order to reduce the space occupied by the wing part of the folding wing UAV as much as possible, the folding wing UAV further includes a second wing connecting rod 4, the first end of the second wing connecting rod 4 is hinged to the second end of the first wing connecting rod 3, the rotor a is installed on the second end of the second wing connecting rod 4, and the first wing connecting rod 3, the second wing connecting rod 4 and the rotor a constitute the wing part of the folding wing UAV; when the first wing connecting rod 3 is in the second state, the second wing connecting rod 4 can be stored in the storage slot 10, so that the wing part of the folding wing UAV can be folded twice and stored in the storage slot 10. It should be noted that in the present invention, the rotor a can also be folded and overlapped, and can even be folded and stored in the storage slot 10, thereby further reducing the space occupied by the wing part.

[0032] Furthermore, the second end of the first wing connecting rod 3 is also provided with a second fixing portion 30, and the first end of the second wing connecting rod 4 is also provided with a third fixing portion 40; when the first wing connecting rod 3 is in the first state, the second fixing portion 30 can be connected with the third fixing portion 40 to relatively fix the first wing connecting rod 3 and the second wing connecting rod 4. Both the second fixing portion 30 and the third fixing portion 40 are provided with threaded holes, and the second fixing portion 30 can be fixedly connected with the third fixing portion 40 by bolts. The bolts are matched with the hinge shafts of the first wing connecting rod 3 and the second wing connecting rod 4 to perform two-point fixation, thereby improving the structural stability of the wing part of the folding wing UAV and preventing the wings from loosening or shaking during operation, thereby causing flight accidents.

[0033] Furthermore, the folding wing UAV further includes a locking member 5, which is mounted on the first fixing portion 11. When the first wing connecting rod 3 is in the first state, the locking member 5 can penetrate the first fixing portion 11 and the first wing connecting rod 3, so that the first wing connecting rod 3 is fixed to the first fixing portion 11. In an embodiment of the present invention, the locking member 5 is threaded, and the locking member 5 sequentially penetrates the first fixing portion 11 and the first wing connecting rod 3 and is threadedly connected with the two, which can further increase the connection stability between the first wing connecting rod 3 and the first fixing portion 11. In the present invention, a plurality of locking members 5 can be provided.

[0034] Further, as attached Figure 7 and 8As shown, in order to ensure the balance of the folding wing UAV, any two opposing wings need to be in a straight line. In the embodiment of the present invention, the UAV body 1 is arranged in a polygonal prism shape, the fixing groove 110 is arranged in a column shape, and the center lines of the fixing grooves 110 arranged on the two first fixing parts 11 arranged on any two opposing side walls of the UAV body 1 are in the same straight line. Therefore, the fixing grooves 110 on any two opposing first fixing parts 11 are all in a straight line, so that the two first wing connecting rods 3 to be installed on the two fixing grooves 110 are in a straight line, thereby ensuring the flight balance of the folding wing UAV.

[0035] Furthermore, since the length of the storage slot 10 is limited by the length of the side wall of the drone body, and the drone body is generally smaller than the extended size of its wing in order to reduce weight, the length of the first wing connecting rod 3 may be greater than the length of the storage slot 10, resulting in the first wing connecting rod 3 being unable to be stored in the storage slot 10 after being folded. In order to prevent the length of the wing from being limited by the length of the storage slot 10, in the embodiment of the present invention, the drone body 1 is further provided with a notch 12 connected to the storage slot 10, and the second end of the first wing connecting rod 3 can extend out of the storage slot 10 from the notch 12, thereby facilitating the storage of the first wing connecting rod 3 of a longer size. Therefore, in another embodiment of the present invention, the wing fixing base 2 is arranged on a side of the storage slot 10 away from the notch 12, and the length of the first wing connecting rod 3 is greater than or equal to the length of the storage slot 10, so that when the size of the drone body 1 is small and the extended size of its wing is large, the wing folding work can still be performed.
