Therefore, the connection between the arms and the main wings needs to withstand significant stress. Thus, effectively and reliably connecting the arms and wings and increasing the stress-bearing capacity of the connection point is crucial. Summary of the Invention

[0008] S3: The arm is coupled to the wing of the UAV via the first reinforcing member, the first reinforcing member being configured to bear compressive stress from both sides inward or tensile stress from the inside out when the UAV takes off or lands.
[0009] Preferably, the first reinforcing member is symmetrically arranged on both sides perpendicular to the long axis of the wing.

[0016] The second region is the accommodating region. After the second reinforcing member, which is adapted to the first reinforcing member, is disposed on both ends of the accommodating region, the first reinforcing member is covered on the second reinforcing member.
[0017] Preferably, the accommodating area is in the shape of an inverted isosceles trapezoid along the length of the arm.
[0018] Preferably, the cross-section of the first reinforcing member is formed by three straight lines and a curve, and the cross-section gradually converges from the straight line connecting opposite ends of the curve to the two straight lines at both ends of the curve.
[0019] Preferably, S3 specifically includes: four first threaded holes are provided on each side of the first reinforcing member along the length of the wing, and eight bolts are passed through the first threaded holes to couple the wing to the arm.

[0025] The beneficial effects of the present invention are as follows: The present invention provides a reinforcing member at the connection between the main wing and the arm, and connects the arm and the wing through the reinforcing member and fixes them with eight bolts.
