Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

The embodiment is described with reference to fig. 1 to 5, and the arm folding mechanism for the unmanned aerial vehicle comprises a middle beam plate 1, a movable member 2 and a pipe clamp 3, wherein the middle beam plate 1 is hinged to one end of the movable member 2, the other end of the movable member 2 is hinged to the pipe clamp 3, and the pipe clamp 3 is hinged to the middle beam plate 1; according to the arrangement, the pipe clamp can be driven to swing through the movement of the movable piece, the support rod 11 is arranged on the middle beam plate 1, the movable piece 2 comprises the connecting rod 21 and the locking piece 22, one end of the connecting rod 21 is hinged to the support rod 11, the other end of the connecting rod 21 is hinged to one end of the locking piece 22, the other end of the locking piece 22 is hinged to the pipe clamp 3, and the locking piece 22 is provided with the tenon 221 for limiting the connecting rod 21; the locking piece is provided with the clamping tenon, when the connecting rod and the locking piece move relatively, the connecting rod stops moving when being tightly propped against the clamping tenon, and the limiting effect on the connecting rod is achieved; the pipe clamp 3 comprises a connecting pipe 31 and a connecting seat 32, the connecting seat 32 is fixedly installed on the connecting pipe 31, a rotating shaft 34 is inserted on the connecting seat 32, a locking piece 22 is rotatably sleeved on the rotating shaft 34, a round rod 321 and an arc-shaped tenon 322 are further arranged on the connecting seat 32, an arm spring 33 is sleeved on the round rod 321, one end of a spring arm of the arm spring 33 is attached to the locking piece 22, and the other end of the spring arm is attached to the arc-shaped tenon 322; the arc clamping tenon and the rotating shaft are used for extruding the machine arm spring, and when the locking piece arranged on the rotating shaft rotates, the machine arm spring is released; preferably, four groups of folding mechanisms are arranged and distributed at four end corners of the middle beam plate; further optimizing, an included angle of an inner angle A formed when the connecting rod 21 and the locking piece 22 are in the unfolding state is an obtuse angle; so set up, increased the swing range of pipe clamp on the one hand, on the other hand conveniently carries out spacing messenger's structure more stable.
