Specifically, referring to Fig. 1-2, described first rotor 21 is connected with described rotor shaft 3 is detachable by the described parts for being rotatably connected. The described parts for being rotatably connected at least comprise: the first motor 41, first dismantles thread set 43 and Foldable assembly 5. For driving, described first rotor 21 rotates described first motor 41, to drive unmanned plane during flying. First motor 41 comprises the first surface 411 and the 2nd surface 412. In the utility model embodiment, it is the upper surface of the first motor 41 that first surface 411 can be understood as, it is the lower surface of the first motor 41 that 2nd surface 412 can be understood as, and described first motor 41 is fixed in described rotor shaft 3 by described first surface 411. Meanwhile, described first rotor 21 is connected with the first surface 411 of described first motor 41 is detachable by described first dismounting thread set 43.
For the mode of connection of the first rotor 21 and the first motor 41, both the first rotor 21 and the first motor 41, by setting up the first dismounting thread set 43, are threaded by the utility model embodiment by the first dismounting thread set 43. Make in actual operation process when needs are to when installing without man-machine multiple rotors or dismantle, only need to rotate described first rotor 21, as turned clockwise the first rotor 21 or be rotated counterclockwise the first rotor 21, the installation or removal between described first rotor 21 and described first motor 41 can be realized. Compared to traditional direct employing bolt, the first rotor 21 is fixed on the first motor 41, when the first rotor 21 is dismantled by needs from the first motor 41, or when installing, all need to turn bolt by extraneous handle, dismounting and the installation work of the first rotor 21 can be completed. And owing to being the individual component of Individual existence for connecting the standing bolt of the first rotor 21 and the first motor 41, when by handle turn bolt unloaded time, often due to the complicacy of execute-in-place environment, very easily cause the loss of standing bolt, and once standing bolt is lost, then just cannot complete the installation work of the first rotor 21 and the first motor 41, namely cause the serious consequence that flight equipment cannot fly. And the utility model embodiment, just by adopting the first dismounting thread set 43 both first rotor 21 and the first motor 41 to be threaded, make the two when installing or dismantle, without the need to by extraneous operational tool (such as handle), quick and convenient, have the advantages that operation efficiency is high.
For the first dismounting thread set 43, please continuing see Fig. 2, described first dismounting thread set 43 at least comprises: the first screw 431, the 2nd screw 432, first screw buckle 433 and the first dismounting nut 436. Wherein, the inwall of described first screw buckle 433 is provided with the first internal thread 434, and the bottom of described first screw buckle 433 offered the first screw 435 so that described first screw buckle 433 is fixed on the first surface 411 of described first motor 41 by described first screw 432 through described first screw 435. The outer wall of described first dismounting nut 436 is provided with first outside screw 437 suitable with described first internal thread 434, and described first dismounting nut 436 top offered the 2nd screw 438 so that described 2nd screw 432 successively through described first rotor 21, described 2nd screw 438 by described first dismounting nut 436 be fixed on described first rotor 21.
Wherein, the first screw buckle 433 is fixed on the first surface 411 of the first motor 41 by the first screw 431, and the first dismounting nut 436 is fixed on the first rotor 21 by the 2nd screw 432. And first the first internal thread 434 offered of the inwall of screw buckle 433, and the first outside screw 437 that the outer wall of the first dismounting nut 436 is offered mates completely, also namely can realize occlusion between the first internal thread 434 and the first outside screw 437 and lock. So just make, when the first rotor 21 is arranged in rotor shaft 3 by needs, owing to the first motor 41 is fixed on the end of rotor shaft 3, also it is about to the first rotor 21 and is arranged on the first motor 41. Now, only need manually to rotate the first rotor 21, first outside screw 437 is engaged mutually with the first internal thread 434, continue to rotate, then the locking of the first dismounting nut 436 and the first screw buckle 433 is realized, owing to the first dismounting nut 436 is fixed on the first rotor 21, the first screw buckle 433 is fixed on the first motor 41, and the locking also namely achieving the first rotor 21 and the first motor 41 (rotor shaft 3) is installed. And when disassembly is desired, now only needing reverse rotation first rotor 21, it is achieved the first outside screw 437 is separated with the first internal thread 434. There is swift to operate, feature easily.
It should be noted that, without man-machine in practical flight process, the sense of rotation of the first rotor 21 is for being rotated counterclockwise direction, now, itself it is the state being in constantly rotation due to the first rotor 21 in flight course, and itself also it is adopt to rotate to realize fastening mode of connection in the utility model embodiment between the first rotor 21 and the first motor 41. Such as, when the first rotor 21 is realize fastening therebetween by turning clockwise relative to the first motor 41, owing to normally rotating to be of the first rotor 21 in flight course is counterclockwise, now along with the counterclockwise normal of the first rotor 21 rotates, also namely the first rotor 21 is equivalent to the first motor 41 and has the driving being rotated counterclockwise. And could realize fastening therebetween by turning clockwise relative to the first motor 41 due to the first rotor 21, otherwise so when occurring that the first rotor 21 is be rotated counterclockwise relative to the first motor 41, namely the fastening relation between the first rotor 21 and the first motor 41 can be caused to occur loosening, even cause the first rotor 21 to fly away from the first motor 41 and cause the phenomenon without man-machine crash to occur.
Therefore, in order to avoid causing the fastening relation between the first rotor 21 and the first motor 41 to occur loosening in flight course due to the first being normally rotated counterclockwise of rotor 21 without man-machine, the utility model embodiment rotates, by between the first rotor 21 and the first motor 41, the direction also being arranged to be rotated counterclockwise in the direction tightened. Namely, also the occlusion locking direction of first outside screw 437 set by outer wall of the first dismounting nut 436 and first internal thread 434 set by inwall of the first screw buckle 433 is also counterclockwise. So just make when the first rotor 21 relative to the first motor 41 be by be rotated counterclockwise realize fastening therebetween time, owing to normally rotating to be of the first rotor 21 in flight course is counterclockwise, now along with the counterclockwise normal of the first rotor 21 rotates, also namely the first rotor 21 is equivalent to the first motor 41 and also has the trend being rotated counterclockwise.
And due to the first rotor 21 be exactly could realize therebetween by being rotated counterclockwise fastening relative to the first motor 41, so on the one hand, effectively prevent when the first rotor 21 is realize occlusion locking by turning clockwise relative to the first motor 41, owing to normally rotating to be of the first rotor 21 causes the fastening relation between the first rotor 21 and the first motor 41 to occur loosening counterclockwise, the first rotor 21 is even caused to fly away from the first motor 41 and cause the technological deficiency without man-machine crash. On the other hand, due to the first rotor 21 itself also it is could realize therebetween by being rotated counterclockwise fastening relative to the first motor 4, when rotating along with the normal counterclockwise of the first rotor 21, and make the first rotor 21 be equivalent to the first motor 41 and also have the trend being rotated counterclockwise, now just also increase the first rotor 21 and the first motor 41 fastening relation therebetween, ensure that the normal safe of flight equipment flies, have the advantages that safety performance is high.
