Referring to fig. 1, the present application provides a drone 100. In one embodiment of the present application, 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, wherein the anti-collision member 31 is disposed on the body 10 and moves 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 application, the body 10 is a main body structure of the unmanned aerial vehicle 100, and may specifically include a body 13, a propeller 15, and a propeller cover 17. At this time, the propeller 15 is connected to the body 13, and the propeller cover 17 is connected to the body 13 around the outside of the propeller 15. The anti-collision member 31 is provided outside the paddle cover 17 and is movable toward the paddle cover 17 by an external force. It will be appreciated that since the paddle cover 17 of the body 10 is formed as a contoured structure of the outermost periphery of the drone 100, the paddle cover 17 is susceptible to contact with an obstacle first. Therefore, when the collision preventing member 31 is arranged on the paddle cover 17, the unmanned aerial vehicle 100 can be better guaranteed to meet the obstacle in the flight process, the collision preventing member 31 in the obstacle detecting assembly 30 can be firstly contacted with the obstacle, and therefore timeliness and effectiveness of the operation of the obstacle detecting assembly 30 are improved. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, the bump guard 31 may be disposed directly on the side of the body 13 when the body 13 is disposed relatively large. The collision preventing member 31 of the obstacle detecting unit 30 may be used to protect the machine body 10, may contact with an obstacle during a flight, and may move toward the machine body 10 when being abutted by the obstacle. The sensing member 33 may be used to detect movement of the collision preventing member 31 when contacting an obstacle, thereby indirectly detecting that the unmanned aerial vehicle 100 encounters the obstacle during the flight. Wherein, the sensing piece 33 can be independently arranged on the paddle cover 17 on the machine body 10; of course, it may be provided separately on the impact member 31; or partially on the paddle cover 17 of the body 10 and partially on the bump guard 31. That is, the installation position of the sensor 33 is not particularly limited in the present application, and it is sufficient to detect the movement of the impact member 31 when it contacts an obstacle.
In the unmanned aerial vehicle 100 according to the present application, when the unmanned aerial vehicle 100 encounters an obstacle during flight, the collision preventing member 31 of the obstacle detecting assembly 30 contacts the obstacle and moves toward the body 10 when the obstacle abuts. At this time, the sensing member 33 in the obstacle detecting assembly 30 may detect the movement of the anti-collision member 31, thereby indirectly detecting that the unmanned aerial vehicle 100 encounters an obstacle during the flight, so that the following unmanned aerial vehicle 100 changes the flight direction in time according to the information detected by the obstacle detecting assembly 30. Moreover, compared with the unmanned aerial vehicle 100 in the prior art, the unmanned aerial vehicle 100 in the scheme generally adopts the active detection obstacle system such as the radar which has high cost, high energy consumption and relatively large volume and increases the weight of the unmanned aerial vehicle 100, the unmanned aerial vehicle 100 in the scheme only can passively detect the movement of the anti-collision member 31, which occurs when contacting the obstacle, by adopting the sensing member 33 which is relatively close to the anti-collision member 31. At this time, the passive detection process of the movement of the crash element 31, that is, the passive detection process of the obstacle is relatively easy to be implemented by the sensing element 33, so that the structure of the sensing element 33 can be relatively simple and the manufacturing cost can be reduced. Meanwhile, the simple passive detection process also enables the energy consumption of the sensing piece 33 in the use process to be smaller than the energy consumption required by active detection obstacle systems such as radars and the like, thereby being beneficial to reducing the use cost of the sensing piece 33. In addition, when the structure is relatively simpler, the volume of the sensing element 33 can be smaller than the volume required by the active detection obstacle system such as radar, thereby being beneficial to reducing the weight of the unmanned aerial vehicle 100 and facilitating the subsequent flight of the unmanned aerial vehicle 100. That is, the 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 and guaranteed the flight effect simultaneously.
Referring to fig. 1, in an embodiment of the present application, the sensing member 33 includes a contact 331 and a sensing contact 333, wherein the contact 331 is disposed on a wall surface of the anti-collision member 31 facing the machine body 10; the sensing contact 333 is disposed on a wall surface of the body 10 facing the anti-collision member 31, and when the anti-collision member 31 is moved toward the body 10 by an external force, the contact 331 can abut against the sensing contact 333 to detect the movement of the anti-collision member 31.
In the present embodiment, the sensing member 33 includes a contact 331 and a sensing contact 333, so that when the unmanned aerial vehicle 100 does not encounter an obstacle, the contact 331 on the anti-collision member 31 is spaced from the sensing contact 333 on the paddle cover 17 on the body 10, and the sensing contact 333 is not electrically conductive. And when the unmanned aerial vehicle 100 encounters an obstacle, the impact member 31 moves toward the body 10 after abutting the obstacle. Meanwhile, the contact 331 moves along with the contact to approach and abut against the sensing contact 333, so that the sensing contact 333 is electrically conducted (specifically, the sensing contact 333 may have an anode contact and a cathode contact which are arranged at intervals, and the contact 331 is electrically conducted when abutting against the anode contact and the cathode contact), thereby detecting that the contact 331 contacts with the sensing contact 333, in other words, detecting that the unmanned aerial vehicle 100 encounters an obstacle signal. In addition, the sensor 33 may include only two parts, i.e., the contact 331 and the sensor 333, and no additional auxiliary detecting part may be provided. The structure of the sensing member 33 is simplified, thereby being beneficial to further reducing the manufacturing cost of the unmanned aerial vehicle 100 and improving the convenience of assembling the unmanned aerial vehicle 100. Meanwhile, since the volumes of the contact 331 and the sensing contact 333 are relatively small, and the stroke required by the contact 331 to move to abut against the sensing contact 333 is also relatively small, the collision preventing member 31 and the machine body 10 can be relatively compact, thereby being beneficial to reducing the overall volume of the unmanned aerial vehicle 100. Of course, it should be noted that, in other embodiments, the sensing device 33 may include a light emitter and a light receiver, which may be disposed on the outer wall surface of the paddle cover 17 of the machine body 10 and are disposed opposite to each other. At this time, the anti-collision member 31 may be provided with a baffle on a wall surface facing the machine body 10, and when the anti-collision member 31 contacts an obstacle and moves toward the machine body 10, the baffle may be inserted between the light emitter and the light receiver to move therewith, and detection of movement of the anti-collision member 31 is achieved by blocking a light path between the light emitter and the light receiver, so that detection of the obstacle encountered by the unmanned aerial vehicle 100 is achieved.
Referring to fig. 1 to 4, in an embodiment of the application, a part of the structure of the contact 331 is embedded in the bump guard 31.
In the present embodiment, the contact 331 is embedded in the anti-collision member 31, so that the space occupied by the contact 331 can be reduced, thereby further improving the installation compactness between the anti-collision member 31 and the machine body 10. At the same time, the contact 331 and the anti-collision member 31 have a relatively large contact area, so that the stability of the contact 331 is improved. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, the contact 331 may be only attached to the surface of the crash piece 31.
In one embodiment of the present application, the contact 331 and the bump 31 are of unitary construction.
In the present embodiment, the contact 331 and the impact member 31 are integrally provided, so that the strength of the two at the joint can be enhanced, thereby being advantageous to further improve the stability of the installation of the contact 331. Meanwhile, the contact 331 and the anti-collision member 31 can be manufactured through integrated forming, so that the processing technology of the contact 331 and the anti-collision member is simplified, and the production efficiency is improved. Of course, it should be noted that, in other embodiments, the contact 331 and the bump protection member 31 may be separately disposed, and then fixed by glue bonding or screw connection.
Referring to fig. 1 to 3, in an embodiment of the application, a part of the sensing contact 333 is embedded in the body 10.
In this embodiment, the sensing contact 333 is embedded in the paddle cover 17 of the body 10, so that the space occupied by the sensing contact 333 can be reduced, which is beneficial to further improving the installation compactness between the anti-collision member 31 and the body 10. At the same time, this arrangement also allows the sensing contact 333 to have a relatively large contact area with the body 10, thereby facilitating improved stability in mounting of the contact 331. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, the sensing contact 333 may be attached only to the surface of the paddle cover 17 of the body 10.
In one embodiment of the present application, the sensing contact 333 and the body 10 are of unitary construction.
In the present embodiment, the sensing contact 333 and the paddle cover 17 of the body 10 are integrally provided, so that the strength of the two at the joint can be enhanced, thereby being beneficial to further improving the stability of the installation of the sensing contact 333. Meanwhile, by the arrangement, the inductive contact 333 and the paddle cover 17 of the machine body 10 can be manufactured through integral molding, so that the processing technology of the inductive contact 333 and the paddle cover is simplified, and the production efficiency is improved. It should be noted that, in other embodiments, the sensing contacts 333 and the paddle cover 17 of the body 10 may be separately provided, and then fixed by glue bonding or screw connection.
Referring to fig. 1 to 4 in combination, in an embodiment of the present application, the crash piece 31 includes a main body 311 and an elastic portion 313, and the main body 311 is disposed at a distance from the machine body 10; the elastic portion 313 has two opposite ends, the opposite ends of the elastic portion 313 are respectively connected to the main body 311 and the machine body 10, the main body 311 can move towards the machine body 10 when receiving an external force, and the sensing member 33 is used for detecting the movement of the main body 311.
In the present embodiment, the impact member 31 is capable of contacting an obstacle via the main body portion 311 and is capable of being connected to the blade cover 17 of the body 10 via the elastic portion 313. The elastic portion 313 has elasticity, so that when the main body 311 contacts an obstacle, the elastic portion 313 can be compressed to move toward the machine body 10, so as to improve the safety of the anti-collision member 31 and ensure that the sensing member 33 can timely detect the obstacle. At this time, the contact point 331 in the sensing piece 33 may be provided on a wall surface of the main body portion 311 facing the paddle cover 17 of the body 10.
In an embodiment of the present application, the elastic portion 313 is a rubber member or a silicone member.
In this embodiment, the elastic portion 313 is made of rubber or silica gel, so that the elastic portion 313 has a certain elasticity, and can be compressed in time when the main body 311 contacts an obstacle, so that the main body 311 moves. At the same time, the elastic portion 313 has a certain hardness, so that the connection supporting function can be better performed on the paddle cover 17 and the main body portion 311 of the machine body 10. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, the elastic member may be a telescopic tube including the paddle cover 17 and the main body 311 connected to the machine body 10, and a spring sleeved outside the telescopic tube.
In one embodiment of the present application, the elastic portion 313 and the main body portion 311 are integrally formed.
In the present embodiment, the elastic portion 313 and the main body portion 311 are integrally provided, so that the strength of the two at the connection portion can be enhanced, thereby being beneficial to improving the stability of the connection of the two. Meanwhile, the anti-collision member 31 can be manufactured through integral molding, so that the processing technology is simplified, and the production efficiency is improved. It should be noted that, in other embodiments, the elastic portion 313 and the main body portion 311 may be separately provided, and then fixed by glue or snap-fit.
Referring to fig. 2 and 3 in combination, in an embodiment of the application, the machine body 10 is provided with an insertion hole 171, and an end of the elastic portion 313 away from the main body 311 is inserted into the insertion hole 171 and is in interference fit with the insertion hole 171.
In this embodiment, the elastic portion 313 is disposed in an interference fit with the machine body 10, so that only a relatively simple structure of the insertion hole 171 is required to be disposed on the paddle cover 17 of the machine body 10, and the relatively complex structure is not required to be disposed for mounting and fixing the elastic member, thereby further reducing the manufacturing cost. Meanwhile, by the arrangement, when the assembly is performed, one end of the elastic part 313 is directly inserted into the insertion hole 171 on the paddle cover 17 of the machine body 10, so that the assembly and fixation can be completed, and the insertion process is simpler, thereby being beneficial to further improving the convenience of assembly. It should be noted that, the present application is not limited thereto, and in other embodiments, the elastic portion 313 and the paddle cover 17 of the machine body 10 may be fixed by glue or screw connection.
Referring to fig. 1 to 4 in combination, in an embodiment of the application, the main body 311 extends along a circumferential direction of the machine body 10 to form a strip structure, and the sensing elements 33 and the elastic portions 313 are spaced apart from each other in an extending direction of the main body 311.
In the present embodiment, the main body 311 is arranged in a strip shape, so that the volume of the main body 311 is relatively small to reduce the overall size. Meanwhile, when the main body 311 is abutted by an obstacle, the main body can be relatively well stressed to move towards the machine body 10. The sensing elements 33 and the elastic portions 313 are distributed at intervals in the extending direction of the main body 311, so that the space of the main body 311 in the length direction can be fully utilized, and the compactness of the distribution is improved. When the paddle cover 17 of the body 10 has a cylindrical structure, the main body 311 may have an arc-shaped plate structure, so as to better adapt to the shape of the body 10, further improve the installation compactness of the two, and reduce the overall volume of the unmanned aerial vehicle 100. In the case where the paddle cover 17 of the body 10 has a square column structure, the main body 311 may have a flat plate structure.

At this time, the main body 311 has a connection relationship only in the middle, and is in a suspended state at both ends, so that the capability of deformation of the anti-collision member 31 is relatively strong, thereby being beneficial to improving the convenience of movement of the main body 311 in the direction towards the machine body 10 when the main body 311 abuts against an obstacle, so as to further ensure timely and effective detection of the obstacle. The number of the sensing elements 33 may be only two, that is, two contact points 331 are respectively disposed at two opposite ends of the main body 311, and two sensing points 333 are disposed on the paddle cover 17 of the machine body 10 and are respectively disposed corresponding to the two contact points 331. Of course, the number of the sensing members 33 may be more. In addition, the present application is not limited thereto, and in other embodiments, two elastic portions 313 may be provided and located at opposite ends of the main body 311, and the sensing element 33 may be disposed corresponding to a middle portion of the main body 311.
Referring to fig. 1 and 2 in combination, in an embodiment of the present application, the number of the obstacle detecting assemblies 30 is at least two, and the at least two obstacle detecting assemblies 30 are uniformly spaced around the circumference of the machine body 10.
In this embodiment, when the anti-collision member 31 is in a strip structure, at least two anti-collision members may be uniformly spaced around the circumference of the machine body 10, so that the obstacle detection assemblies 30 at different positions can detect obstacles in different directions, thereby being beneficial to improving the detection effect of the unmanned aerial vehicle 100 on the obstacles. Wherein the number of the obstacle detecting assemblies 30 may be two, three or more, etc. Of course, it should be noted that, when the anti-collision member 31 is disposed in a ring shape, the number of the anti-collision members 31 may be only one and surround the outer side of the paddle cover 17 of the machine body 10, and the number of the sensing members 33 may be at least two and disposed at uniform intervals along the circumferential direction of the anti-collision member 31.
