The unmanned aerial vehicle 10 includes a body 11, a boom 12, a driving device 13, and a propeller assembly 14. The horn 12 is disposed around the body 11 and is fixedly connected to the body 11. The drive device 13 is installed at the end of the arm 12 far away from the fuselage 11, the propeller assembly 14 is installed on the drive device 13, and the drive device 13 is used for driving the propeller assembly 14 to operate, so as to provide power for the unmanned aerial vehicle 10.
In the embodiment of this application, this screw subassembly 14 can solve among the prior art because the unmanned aerial vehicle 10 flight that paddle 200 inertial action caused is unstable to and the serious technical problem of paddle 200 wearing and tearing, thereby reach unmanned aerial vehicle 10 flight stability, extension unmanned aerial vehicle 10 life's purpose. Under the condition that this screw subassembly 14 solved above-mentioned technical problem, can make this unmanned aerial vehicle 10 also solve the unmanned aerial vehicle 10 flight unstability that causes among the prior art because paddle 200 inertial action to and paddle 200 wears serious technical problem.
Referring to fig. 2 and 3, the propeller assembly 14 includes a blade 200, a mounting body 100, a limiting member 300, and a movable member 400. The mounting body 100 is mounted on the driving device 13, and the driving device 13 can drive the mounting body 100 to rotate when operating. Paddle 200 is rotatably coupled to mounting body 100 and can rotate relative to mounting body 100 to an extended state. It should be noted that, in the case that the blade 200 is in the deployed state, the blade 200 may rotate following the mounting body 100, thereby providing power to the unmanned aerial vehicle 10. In addition, for the transportation or the placement of convenient unmanned aerial vehicle 10, paddle 200 can be installed the main part 100 relatively and rotate, makes paddle 200 leave the state position of expansion to in order to reach folding paddle 200's purpose, can reduce the shared space of unmanned aerial vehicle 10 this moment, can regard as paddle 200 to install the main part 100 relatively and rotate to fold condition this moment.
In the prior art, the blades 200 are rotatably connected with the mounting body 100, so that when the driving device 13 changes the rotation speed, under the inertia effect of the blades 200, the blades 200 swing relative to the mounting body 100, so that the propeller assembly 14 is unbalanced as a whole, and even the unmanned aerial vehicle 10 is unstable in flight; furthermore, since the unmanned aerial vehicle 10 needs to change the flying speed or flying direction of the unmanned aerial vehicle 10 by changing the output speed of the driving device 13 during flying, the output speed of the driving device 13 can be changed frequently, the rotating speed of the blade 200 can be changed frequently, and the blade 200 can swing frequently relative to the mounting body 100, in such a case, the abrasion between the blade 200 and the mounting body 100 can be increased, the mounting gap between the mounting body 100 and the blade 200 can be increased, and the unstable flying condition of the unmanned aerial vehicle 10 can be caused by the unstable position of the blade 200 while the service life of the blade 200 and the mounting body 100 is reduced.
In order to solve the above technical problem, in the embodiment of the present application, the limiting member 300 is fixed to the blade 200, and the moving member 400 is movably disposed on the mounting body 100. When the blade 200 is in the extended state, the limiting member 300 is engaged with the moving member 400, so that the limiting member 300 is fixed with respect to the mounting main body 100. In other words, under the condition that the blade 200 is in the deployed state, through the mutual cooperation between the limiting member 300 and the moving member 400, under the condition that the limiting member 300 is fixed relative to the mounting main body 100, the blade 200 can be fixed relative to the mounting main body 100, and therefore, even if the driving device 13 changes the output speed thereof, the swinging of the blade 200 relative to the mounting main body 100 can be limited through the limiting member 300 and the moving member 400, so that the problems that the unmanned aerial vehicle 10 is unstable in flight and the mounting main body 100 and the blade 200 are seriously worn due to the swinging between the blade 200 and the mounting main body 100 in the prior art are solved, and the technical problems that the unmanned aerial vehicle 10 is unstable in flight and the blade 200 is seriously worn due to the inertia effect of the blade. In addition, the movable member 400 can move under the action of external force to disengage the limiting member 300. When the blade 200 needs to be folded, the movable element 400 is disengaged from the limiting element 300 through an external force, and the blade 200 can freely rotate relative to the installation main body 100 due to the fact that the limiting element 300 is disengaged from the movable element 400, so that the blade 200 can leave the position of the unfolded state to rotate to the position of the folded state.
It should be noted that, in other embodiments of the present application, the limiting member 300 may also be fixed on the mounting main body 100, and accordingly, the movable member 400 is movably disposed on the blade 200, so that the blade 200 can be fixed relative to the mounting main body 100 through the cooperation between the movable member 400 and the limiting member 300. Therefore, in the embodiment of the present application, the stopper 300 is fixed to one of the blade 200 and the mounting body 100, and the movable member 400 is movably disposed on the other of the blade 200 and the mounting body 100.
As described above, when the blade 200 in the propeller assembly 14 is in the deployed state, the stopper 300 is fixed with respect to the mounting body 100 by the engagement between the stopper 300 and the movable member 400, so that the blade 200 can be fixed with respect to the mounting body 100; at paddle 200 pivoted in-process, under the condition that unmanned aerial vehicle 10 changed paddle 200's slew velocity, fixed action through moving part 400 can prevent that paddle 200 from taking place the swing under the inertial action relative installation main part 100 to reach the purpose of firm paddle 200, consequently can solve among the prior art because the unmanned aerial vehicle 10 flight instability that paddle 200 inertial action caused, and the serious technical problem of paddle 200 wearing and tearing. The unmanned aerial vehicle 10 can fly stably, and the operation specified by a user can be effectively finished; and reach the purpose that improves unmanned aerial vehicle 10 life.
In the embodiment of the present application, the mounting body 100 includes a first mounting part 110 and a second mounting part 120, the first mounting part 110 is mounted on the driving device 13, and the driving device 13 drives the first mounting part 110 to rotate when outputting power. In addition, the first mounting part 110 and the second mounting part 120 clamp the blade 200, and when the first mounting part 110 rotates, the second mounting part 120 is driven to rotate at the same time, and the first mounting part 110 and the second mounting part 120 drive the blade 200 to rotate together. Paddle 200 is rotatably coupled to both first mount 110 and second mount 120, and paddle 200 may be rotated to an extended position or a collapsed position relative to first mount 110 and second mount 120.
Alternatively, in some embodiments of the present application, the limiting member 300 may be provided as a sheet structure, and the limiting member 300 is provided between the blade 200 and the first mounting member 110. The movable member 400 is movably connected to the first mounting member 110. The rotation plane of the blade 200 is substantially parallel to the plane of the first mounting member 110, which is engaged with the limiting member 300, so that the limiting member 300 can rotate relative to the first mounting member 110 conveniently when the blade 200 rotates relative to the first mounting member 110.
Referring to fig. 3, 4 and 5, the movable member 400 includes a fitting portion 410, and the mounting body 100 is provided with a guide passage 111. The fitting portion 410 is movably fitted with the guide passage 111, and the fitting portion 410 can slide in the extending direction of the guide passage 111. The matching portion 410 extends out of the guide channel 111 to be clamped with the limiting member 300, so as to realize clamping of the limiting member 300 and the movable member 400, as shown in fig. 3 and 4; alternatively, the engaging portion 410 is retracted into the guiding channel 111 by an external force to disengage the position-limiting member 300, as shown in fig. 5. Alternatively, in the embodiment of the present application, the guide passage 111 may be a hole opened on the first mounting member 110 for guiding, and the guide passage 111 is substantially perpendicular to the rotation plane; the engaging portion 410 is movably disposed in the guide passage 111 and is movable along the guide passage 111, i.e., the engaging portion 410 is movable on a path perpendicular to the rotation plane to selectively extend or retract the guide passage 111. Under the condition that the matching part 410 extends out of the guide channel 111, the matching part 410 can be clamped with the limiting piece 300; in the case where the engaging portion 410 is retracted into the guide channel 111, the engaging portion 410 is disengaged from the limiting member 300, and the limiting member 300 and the blade 200 can freely rotate relative to the first mounting member 110.
It should be noted that, in other embodiments of the present application, the arrangement manner of the matching portion 410 and the guiding channel 111 may be different, so that the matching portion 410 and the limiting member 300 are engaged with each other differently. For example, the guide channel 111 is provided as an elongated hole, the fitting portion 410 is movably fitted with the guide channel 111, and the fitting portion 410 can slide along the guide channel 111 to selectively move away from or close to the limiting member 300; when the matching part 410 is located at the end of the guide channel 111 close to the limiting member 300, the matching part 410 can be clamped with the limiting member 300; when the engaging portion 410 is located at the end of the guide channel 111 far from the limiting member 300, the engaging portion 410 is separated from the limiting member 300, so that the limiting member 300 and the blade 200 can be conveniently rotated relative to the first mounting member 110.
Alternatively, referring to fig. 6 and 7 in combination, in the embodiment of the present application, the cross-section of the matching portion 410 is substantially waist-shaped, in other words, the cross-sectional shape of the matching portion 410 can be regarded as a shape formed by two semicircular patterns and a square pattern together, wherein the square is arranged between the two semicircular patterns, and the straight line side of the semicircular pattern coincides with the straight line side of the square pattern. Of course, the fitting portion 410 may be provided in other shapes, such as an oval shape, a circular shape, a square shape, a triangular shape, a parallelogram shape, or other irregular shapes. Correspondingly, the shape of the guide channel 111 is adapted to the mating portion 410, i.e. the shape of the guide channel 111 is substantially the same as the mating portion 410.
Further, with continued reference to fig. 3, 4 and 5, in the embodiment of the present application, the propeller assembly 14 further includes an elastic member 510. The elastic member 510 is disposed inside the guide passage 111 and connected with the fitting part 410. And, in case that the fitting part 410 is retracted into the guide passage 111, the elastic member 510 is elastically deformed. In other words, when the engaging portion 410 retracts into the guide channel 111 under the action of an external force, the elastic member 510 is elastically deformed by the movement of the engaging portion 410, and when the action of the external force is cancelled, the elastic restoring force of the elastic member 510 can make the engaging portion 410 extend out of the guide channel 111, so that the engagement between the engaging portion 410 and the limiting member 300 can be facilitated. Optionally, in the embodiment of the present application, the limiting member 300 abuts against between the bottom wall of the guide channel 111 and the engaging portion 410, so that, when the engaging portion 410 retracts into the guide channel 111, the engaging portion 410 compresses the elastic member 510, thereby elastically deforming the elastic member 510; in the case where the external force is removed, the elastic member 510 pushes the fitting portion 410 out of the guide passage 111 by the elastic restoring force.
Of course, in other embodiments of the present application, the elastic member 510 may be disposed differently, for example, one end of the elastic member 510 is connected to the sidewall of the guide channel 111, and the other end is connected to the fitting part 410, and in a case where the fitting part 410 is retracted into the guide channel 111, the fitting part 410 stretches the elastic member 510, thereby elastically deforming the elastic member 510. For another example, in a case that the movement manner of the matching portion 410 along the guiding channel 111 is "selectively far away from or close to the limiting member 300", the elastic member 510 may be abutted between the matching portion 410 and the sidewall of the guiding channel 111, so that when the matching portion 410 moves away from the limiting member 300, the elastic member 510 may be compressed by the matching portion 410 and the sidewall of the guiding channel 111 together, and when the external force is removed, the matching portion 410 moves close to the limiting member 300 by the elastic restoring action of the elastic member 510.
Alternatively, referring to fig. 8 and fig. 9 in combination, in other embodiments of the present application, the arrangement of the position limiting member 300 and the moving member 400 may adopt other arrangements. For example, the limiting member 300 is a cylindrical structure fixed on the blade 200, the limiting member 300 is disposed substantially perpendicular to the rotation plane of the blade 200, and the limiting member 300 protrudes from one side of the blade 200. The movable member 400 is movably disposed on the second mounting member 120, and the movable member 400 can move relative to the second mounting member 120 to selectively approach or separate from the limiting member 300. For the purpose of fixing the blade 200 with respect to the mounting body 100, the moving member 400 cooperates with the stopper 300 to fix the mounting body 100 and the blade 200 with respect to each other; moreover, under the action of an external force, the movable member 400 can move away from the limiting member 300 to disengage from the limiting member 300, so as to release the engagement relationship between the limiting member 300 and the movable member 400, thereby enabling the blade 200 to freely rotate relative to the mounting body 100.
