[0040] Through the above arrangement, the transparent glass cover 2 and the box body 1 are connected without affecting the sealing performance, and also without affecting the detection of sensors and sensing components. The partition 10 and the box body 1 are slidingly arranged, which does not affect the longitudinal reciprocating movement of the partition 10, and can also provide support and limiting effects for the partition 10. The AC motor 6 moves through the partition 10 and the output end is engaged with the second output wheel 42. The partition 10 is used to provide support and fixation for the AC motor 6, and will not affect the output end of the AC motor 6 to drive the second output wheel 42 to rotate. The semicircular ring 9 and the half gear ring 8 can provide a limit for the first gear 48, limit the moving path of the first gear 48, and at the same time, the half gear ring 8 cooperates with the first gear 48 to drive the visual sensor 3 to rotate back and forth horizontally, so that the detection range of the visual sensor 3 is expanded.

[0041] Reference Figure 2 , 5A reciprocating mechanism 4 is provided at the upper part of the partition 10 and the same side as the AC motor 6, and the reciprocating mechanism 4 includes a first rotating shaft 41 that movably penetrates the upper surface of the partition 10 and the AC motor 6 on the same side, and the lower surface of the first rotating shaft 41 is fixedly connected to the inner surface of the second output wheel 42, and the first output wheel 7 is meshed on one side of the second output wheel 42, and the upper surface of the first rotating shaft 41 is fixedly connected to the middle part of the lower surface of the eccentric wheel 43, and the outer ring side of the upper surface of the eccentric wheel 43 is fixedly connected to the lower surface of the eccentric column 44, and the outer surface of the eccentric column 44 It is set as a smooth plane and is slidably connected with the hollow connecting rod 45 which is also set as a smooth inner surface, and the inner surface of the hollow connecting rod 45 away from the eccentric column 44 is slidably connected to the lower outer surface of the second rotating shaft 47, and the upper outer surface of the second rotating shaft 47 is slidably connected to the inner surface of the first gear 48, and the upper part of the first gear 48 is fixed to the visual sensor 3, and the middle inner surface of the hollow connecting rod 45 is slidably set to the upper outer surface of the fixed column 46, and the lower surface of the fixed column 46 is fixed to one side of the upper surface of the partition 10.

[0042] Through the above arrangement, the first output wheel 7 drives the second output wheel 42 meshing therewith to rotate, and the rotation of the second output wheel 42 drives the first rotating shaft 41 to rotate. The rotation of the first rotating shaft 41 will drive the eccentric wheel 43 and the eccentric column 44 to make eccentric motion, thereby driving the hollow connecting rod 45 to realize reciprocating motion. When the hollow connecting rod 45 reciprocates back and forth, it drives the second rotating shaft 47 to reciprocate back and forth in the semicircular ring 9, and the second rotating shaft 47 can also drive the first gear 48 to realize reciprocating motion in the semicircular ring 9, and realize self-rotation by meshing with the half gear ring 8, while driving the visual sensor 3 to realize left and right rotation. The fixed column 46 arranged in the middle of the hollow connecting rod 45 can provide support for the movement of the hollow connecting rod 45. Since it is movably arranged, it will not affect the movement of the hollow connecting rod 45, but only plays a left and right limiting role for the hollow connecting rod 45 when it moves.

[0043] Reference Figure 3 , 4 The lifting mechanism 5 includes a servo motor 51 fixedly arranged in the middle of the lower surface of the inner cavity of the box body 1, and the output end surface of the servo motor 51 is fixedly connected to the surface of one end of the worm 54, and the outer surfaces of both ends of the worm 54 are movably penetrated through the inner surfaces of both sides of the first base 52, and the lower surface of the first base 52 is fixedly connected to one side of the bottom surface of the inner cavity of the box body 1, and the upper part of the worm 54 is meshed with the worm wheel 55, and the middle part of the worm wheel 55 is fixedly penetrated by the transmission rod 56, and both ends of the transmission rod 56 are movably penetrated through the second base 53, and are rotatably connected to the two ends of the second base 53, and the lower surface of the second base 53 is fixedly connected to one side of the bottom surface of the inner cavity of the box body 1, and at the same time, the lower part of the opposite side surface of the second base 53 is fixedly connected to the two side surfaces of the middle part of the first base 52, and the outer surfaces of both sides of the transmission rod 56 are fixedly connected to the inner surfaces of the two second gears 57, and the second gears 57 are meshed with a gear ring 58.

[0044] The outer surface of one side of the gear ring 58 is fixedly connected to the surface of one side of the first connecting rod 11, and the surface of the first connecting rod 11 away from the gear ring 58 is fixedly connected to the surface of one side of the rotating shaft 12, and the end of the rotating shaft 12 away from the first connecting rod 11 movably passes through one end of the second connecting rod 13, and the surface of the second connecting rod 13 away from the rotating shaft 12 is fixedly connected to the surface of one side of the gasket 14, and at the same time, the surface of the gasket 14 away from the second connecting rod 13 is fixedly connected to the lower surface of the partition 10 through screws.

[0045] Through the above arrangement, the output end of the servo motor 51 rotates, driving the worm 54 to rotate in the first base 52. The rotation of the worm 54 drives the worm wheel 55 and the transmission rod 56 to rotate in the second base 53, and then drives the second gear 57 and the gear ring 58 meshing with the second gear 57 to rotate together. The rotation of the gear ring 58 drives the first connecting rod 11 to rotate. The first connecting rod 11 then drives the second connecting rod 13 to move up and down through the rotating shaft 12. Finally, the second connecting rod 13 drives the partition 10 to move together, thereby realizing the rising and falling of the partition 10.

[0046] It should be noted that the device also requires a controller or control unit for the servo motor 51 and the AC motor 6, and the visual sensor 3 needs to be connected to the aircraft computer board. Since they are all existing technologies, they will not be elaborated here. In the device, the servo motor 51, the AC motor 6 and the visual sensor 3 are all existing technologies and will not be described in detail here.

[0047] The implementation principle of the obstacle avoidance detection structure of a flying device in an embodiment of the present application is as follows: when the flying device is preparing to take off, a signal is given to the visual sensor 3, the servo motor 51 and the AC motor 6 through the computer version, so that the visual sensor 3, the servo motor 51 and the AC motor 6 work, and the output shaft of the servo motor 51 rotates, driving the worm 54 to rotate, and the worm 54 drives the worm wheel 55 and the transmission rod 56 to rotate, and then drives the second gear 57 and the gear ring 58 to rotate, thereby driving the first connecting rod 11 to rotate and drive the second connecting rod 13 to move longitudinally, pushing the partition 10 upward, and when the partition 10 is flush with the upper opening of the box body 1, the servo motor 51 stops working, the worm wheel 55 and the worm 54 limit each other, and the partition 10 can be fixed.

[0048] At the same time, the AC motor 6 works, and the output end of the AC motor 6 rotates, driving the second output wheel 42 to rotate. The rotation of the second output wheel 42 drives the first rotating shaft 41 to rotate. The rotation of the first rotating shaft 41 drives the eccentric wheel 43 and the eccentric column 44 to rotate, driving the hollow connecting rod 45 to move outside the fixed column 46, so that the second rotating shaft 47 moves in the semicircular ring 9, and at the same time drives the gear ring 58 to move on the surface of the semi-gear ring 8, thereby driving the visual sensor 3 to rotate left and right, increasing the detection range.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
