Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the features of the following embodiments and examples may be combined with each other without conflict.

As shown in fig. 1-5, a foldable tail structure for foldably connecting a fuselage main body 1 and a tail 2 comprises a connecting part 3, wherein the connecting part 3 comprises a fuselage main body inner insert 31, a tail inner insert 32, a folding joint hinge 33 respectively connected with the fuselage main body inner insert and the tail inner insert and movably connecting a shell of the fuselage main body and a shell of the tail, the folding joint hinge 33 is supported and connected by a folding joint hinge support base 331 arranged on the fuselage main body inner insert, the connecting part 3 further comprises an anti-lock tail quick release assembly 34 arranged outside the fuselage main body inner insert 31 and a lock position member 35 arranged outside the tail inner insert 32 and capable of being mutually buckled with the anti-lock tail quick release assembly 34, when the tail 2 and the fuselage main body 1 are folded, the anti-lock tail quick release assembly 34 is separated from the lock position member 35, when the fuselage main body 1 and the tail 2 are unfolded, the machine body 1 and the machine tail 2 are fixed in the unfolding direction through the fastening of the anti-falling lock tail quick-release assembly 34 and the locking piece 35.

Specifically, the anti-releasing locking tail quick-release member 34 includes a connecting rod 341, a locking pressing plate 342 and a pressing plate pull ring 343, a first end of the connecting rod 341 is connected to the main body 1, a second end is provided with a first fixing pin 344, one end of the locking pressing plate 342 is provided with a boss 3421, a pin hole is arranged in the boss 3421, the first fixing pin 344 is arranged in the pin hole and can freely rotate in the pin hole, an end surface of the boss 3421 is an arc convex surface 34211, two side surfaces of the arc convex surface are planes parallel to each other, an upper surface of the locking pressing plate 342 is provided with a placing space 3422 of the pressing plate pull ring, the other end of the locking pressing plate 342 is further provided with a pin 3423, one end of the pressing plate pull ring 343 is rotatably connected to the pin 3423 and can be placed in the placing space 3422 of the pressing plate pull ring when rotating to the placing space 3422 of the pressing plate pull ring, in addition, magnets 3422 and 343 of the pressing plate pull ring are further provided with magnets 3424 capable of magnetically attracting each other, the pressing plate tab 343 is fixed in the placing space 3422 by a magnet.

Position locking piece 35 is including setting up tail concave surface piece 351 on tail 2, locking pressing plate 342 is under the drive of pressing plate pull ring 343, moves position locking piece 35 department on the tail through connecting rod 341, and the concave surface of tail concave surface piece 351 on position locking piece 35 and the arc convex surface interference fit joint on the boss 3421 realize that anticreep lock tail quick detach subassembly is connected with the locking of position locking piece.

For better implementation, the first end of the connecting rod 341 is further provided with a second fixing pin 345, the second fixing pin 345 is sleeved with a body fixing hinge support seat 4, and the body fixing hinge support seat 4 is fixed with the body 1.

In this embodiment, when the locking pressing plate 342 is attached to the tail 2, the body fixing hinge support 4, the connecting rod 341 and the locking pressing plate 342 are in a plane, two joints of the body fixing hinge support 4, the connecting rod 341 and the locking pressing plate 342 form dead points, and the convex surface of the locking pressing plate has interference with the concave surface of the tail on the tail, so that the tail is locked with the body, and thus, the body of the body and the tail are unfolded along a straight line, when the pressing plate pull ring 343 is pulled open, the locking pressing plate is pulled out along the belt, the arc-shaped convex surface of the boss 3421 of the locking pressing plate 342 leaves the concave surface of the tail concave surface block 351 on the tail 2, and the tail is released, can be folded, and is connected by the folding joint hinge 33.

In addition, tail concave surface piece 351 uses low coefficient of friction wear-resisting material, and is fixed through screw and tail built-in fitting, can dismantle the change and guarantee to compress tightly the effect, conveniently maintains the maintenance.

It should be noted that a pressing plate pull ring barb 3431 is further disposed below a side of a connection portion of the pressing plate pull ring 343 and the pin 3423, a hole 21 is further disposed on the housing of the machine tail 2, when the pressing plate pull ring 343 is in a locked state, the pressing plate pull ring barb 3431 can be hooked on the hole 21, so that the pressing plate pull ring 343 is fixed outside the housing of the machine tail 2, and the pressing plate pull ring barb 3431 always buckles the machine tail housing, thereby playing a role in preventing falling off. And the force arm of the pressing plate pull ring barb 3431 is short, the force arm of the magnet is long, and larger force is needed for ejecting the pull ring barb in the tail shell, so that the pressing plate can be prevented from being separated from the dead point position due to vibration.

In order to better position the machine body main body 1 and the machine tail 2 when the machine body main body 1 and the machine tail 2 are unfolded, a positioning insertion hole 11 is formed in the end face of an insert in the machine body main body 1, a positioning taper pin 22 is arranged on the end face of the insert in the machine tail 2, and when the machine body main body 1 and the machine tail 2 are unfolded, the machine body main body 1 and the machine tail 2 are in touch positioning connection through the insertion connection of the positioning taper pin 22 and the positioning insertion hole 11.

Since the pressing plate protrusion 343 and the locking pressing plate 342 are attracted by the magnets, the pressing plate protrusion 343 is always kept in a closed state.

In addition, the back of fuselage fixed hinge supporting seat 4 is provided with fuselage fixed hinge support location boss 41, set up positioning groove 22 on the fuselage main part 2, fixed hinge supporting seat 4 accessible fixed hinge support location boss 41 fast with positioning groove 22 location connection. The fixed hinge supporting seat 4 of the machine body is fixed with the embedded part in the main body shell of the machine body in a screw locking mode, and the fixed hinge supporting and positioning boss 41 of the machine body is positioned to improve the assembling and positioning precision and increase the connecting strength.

This application is through setting up fuselage main part and tail components of a whole that can function independently to through the mutual lock locking of anticreep lock tail quick detach subassembly that sets up in the fuselage main part and the lock position piece of setting on the tail, realize the foldable connection of tail and fuselage main part, volume when having reduced unmanned aerial vehicle assembly and transportation has saved assembly space and transportation space, has saved the cost, and, simple structure, practicality, safety.
