Referring to fig. 1, the present invention provides an unmanned aerial vehicle 100. In an embodiment of the present invention, the drone 100 includes a body 10 and an obstacle detection assembly 30. The obstacle detection assembly 30 includes an anti-collision member 31 and a sensing member 33, the anti-collision member 31 is disposed on the body 10 and can move toward the body 10 when being subjected to an external force, and the sensing member 33 is used for detecting the movement of the anti-collision member 31 to acquire obstacle information, so that the unmanned aerial vehicle 100 can change the flight direction in time according to the obstacle information.
In an embodiment of the present invention, the main body 10 is a main structure of the drone 100, and may specifically include a fuselage 13, a propeller 15, and a paddle cover 17. At this time, the propeller 15 is connected to the body 13, and the propeller cover 17 surrounds the outside of the propeller 15 and is connected to the body 13. The anti-collision piece 31 is arranged on the outer side of the paddle cover 17 and can move towards one side of the paddle cover 17 under the action of external force. It can be understood that, since the paddle housing 17 of the body 10 is formed as an outline structure of the outermost periphery of the drone 100, the paddle housing 17 is easily brought into contact with an obstacle first. Consequently on setting up anticollision piece 31 on oar cover 17, when assurance unmanned aerial vehicle 100 that can be better meets the barrier in the flight process, anticollision piece 31 among this obstacle detection subassembly 30 can contact with the barrier at first to be favorable to improving timeliness and the validity of this obstacle detection subassembly 30 work. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, the bumper 31 may be disposed directly on the side of the fuselage 13 when the fuselage 13 is relatively large. The bumper 31 of the obstacle detection assembly 30 may be used to protect the body 10, may first contact an obstacle during flight, and may move toward the body 10 when abutted by the obstacle. The sensing element 33 can be used for detecting the movement of the collision-prevention element 31 when contacting an obstacle, thereby indirectly detecting that the unmanned aerial vehicle 100 encounters the obstacle in the flying process. Wherein, the sensing member 33 can be separately disposed on the paddle cover 17 of the machine body 10; of course, the bumper may be separately provided on the bumper 31; or partially on the paddle cover 17 of the machine body 10 and partially on the bumper 31. That is, the installation position of the sensing member 33 is not specifically limited in this application, and it is sufficient to detect the movement of the collision prevention member 31 when contacting an obstacle.
In the flight process of the unmanned aerial vehicle 100 according to the technical scheme of the invention, when the unmanned aerial vehicle 100 encounters an obstacle, the anti-collision piece 31 in the obstacle detection assembly 30 contacts with the obstacle and moves towards the body 10 under the abutment of the obstacle. At this moment, the motion that the response piece 33 among the obstacle detection subassembly 30 can take place to anticollision piece 31 detects to realized that ground detection unmanned aerial vehicle 100 has met the barrier in the middle of the flight process, so that follow-up unmanned aerial vehicle 100 comes timely change flight direction according to the information that obstacle detection subassembly 30 detected. And, compare in unmanned aerial vehicle 100 among the prior art generally adopt with high costs, the energy consumption is big to and the volume is great relatively and increase the initiative detection obstacle systems such as the radar of unmanned aerial vehicle 100 weight, unmanned aerial vehicle 100 in this scheme only through adopt with anticollision 31 relatively more be close to the response piece 33 come to the anticollision 31 in the motion that contact obstacle takes place carry out passive detection can. At this time, the passive detection process of the sensing member 33 on the movement of the collision-proof member 31 is relatively easy to be implemented, in other words, the passive detection process on the obstacle is relatively easy to be implemented, so that the structure of the sensing member 33 can be relatively simple, which is beneficial to reducing the manufacturing cost. Meanwhile, the energy consumption of the sensing element 33 in the using process can be smaller than that of an active obstacle detection system such as a radar in the simple passive detection process, so that the use cost of the sensing element 33 is reduced. In addition, when the structure setting is comparatively simple relatively, also make the required volume that is less than initiative detection obstacle systems such as radar that the volume of response piece 33 also can set up to be favorable to reducing the weight of unmanned aerial vehicle 100 self and be convenient for follow-up unmanned aerial vehicle 100's flight. That is, unmanned aerial vehicle 100 in this scheme has reduced unmanned aerial vehicle 100's manufacturing and use cost on the basis that the realization can detect the barrier, has also reduced unmanned aerial vehicle 100 self weight simultaneously and has guaranteed the flight effect.

In this embodiment, the sensing member 33 includes the contact point 331 and the sensing contact point 333, so that when the unmanned aerial vehicle 100 does not encounter an obstacle, the contact point 331 on the bumper 31 is spaced from the sensing contact point 333 on the blade cover 17 on the airframe 10, and at this time, the sensing contact point 333 is not electrically conducted. And when the unmanned aerial vehicle 100 encounters an obstacle, the collision prevention piece 31 moves toward the machine body 10 after abutting against the obstacle. Meanwhile, the contact point 331 moves along with the movement of the contact point 331 to approach and abut against the sensing contact point 333, so that the sensing contact point 333 is electrically conducted (specifically, the sensing contact point 333 may have a positive contact point and a negative contact point which are arranged at intervals, and the contact point 331 is electrically conducted when abutting against the positive contact point and the negative contact point), and then the contact between the contact point 331 and the sensing contact point 333 is detected, in other words, the unmanned aerial vehicle 100 meets an obstacle signal is detected. In addition, since the sensor 33 only includes two parts, i.e., the contact 331 and the sensing contact 333, it is not necessary to additionally provide another auxiliary detecting part. So make this response piece 33's structure obtain simplifying to be favorable to further reducing the manufacturing cost of unmanned aerial vehicle 100 and improving the convenience of unmanned aerial vehicle 100 equipment. Meanwhile, the volumes of the contact point 331 and the induction contact point 333 are relatively small, and the required stroke of the contact point 331 when the contact point 331 moves to abut against the induction contact point 333 is also relatively small, so that the anti-collision piece 31 and the machine body 10 can be relatively compact, and the whole volume of the unmanned aerial vehicle 100 can be reduced. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, the sensing element 33 may also include a light emitter and a light receiver, and both the light emitter and the light receiver may be disposed on the outer wall surface of the paddle cover 17 of the machine body 10 and disposed oppositely. At this moment, the wall surface of the collision-prevention piece 31 facing the machine body 10 can be provided with a baffle plate, and when the collision-prevention piece 31 contacts the obstacle and moves towards the machine body 10, the baffle plate can move along with the obstacle and be inserted between the light emitter and the light receiver, and the detection of the movement of the collision-prevention piece 31 is realized by blocking the light path between the light emitter and the light receiver, so that the detection of the obstacle encountered by the unmanned aerial vehicle 100 is realized.

Meanwhile, when the main body 311 is abutted by an obstacle, it can be relatively well forced to move in the direction of the machine body 10. And the sensing piece 33 and the elastic part 313 are distributed at intervals in the extending direction of the main body part 311, so that the space of the main body part 311 in the length direction can be fully utilized by the two parts, and the compactness of the distribution is improved.
