[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figure 1-Figure 4 The unmanned aerial vehicle airborne gimbal shown in the figure includes a base 1, a connecting rod assembly is connected to the rear side wall of the base 1, the other end of the connecting rod assembly is connected to the unmanned aerial vehicle, a mounting groove 2 is opened in the base 1 along the length direction, a strip groove 3 is opened above the mounting groove 2, a bidirectional threaded rod 4 is rotatably arranged between the inner walls at both ends of the mounting groove 2, two nuts 5 are symmetrically arranged on the bidirectional threaded rod 4 with thread matching, a connecting block 6 is fixedly connected above the two nuts 5, the two connecting blocks 6 are both located in the strip groove 3, the upper ends of the two connecting blocks 6 are fixedly connected to a fixing plate 7, the two fixing plates 7 are arranged parallel to each other, and a fixing motor 8 is also fixedly arranged on the side wall of the base 1, and the output shaft of the fixing motor 8 is coaxially fixedly connected to the bidirectional threaded rod 4.

[0022] It should be noted that: when it is necessary to fix cameras of different sizes, the camera to be fixed is placed in the middle of the upper end surface of the base 1, and then the fixing motor 8 is started to drive the bidirectional threaded rod 4 to rotate forward. Under the forward rotation of the bidirectional threaded rod 4, the two nuts 5 symmetrically arranged on the bidirectional threaded rod 4 are opened to move similarly, and then the two fixing plates 7 are driven to move similarly through the two connecting blocks 6, thereby achieving a clamping and fixing effect for the camera located in the middle.

[0023] Furthermore, threaded holes 13 are provided on the rear side wall and the bottom wall of the base 1, an L-shaped connecting plate 14 is provided on the rear side wall of the base 1, a fixing hole 15 is provided on the L-shaped connecting plate 14, a screw 16 is provided at the fixing hole 15, the screw 16 is threadedly matched with the threaded hole 13, and the connecting rod assembly is connected to the side wall of the L-shaped connecting plate 14.

[0024] Among them, the connecting rod assembly includes a first connecting rod 17 and a second connecting rod 18. The first connecting rod 17 is fixedly connected to the side wall of the L-shaped connecting plate 14. A rotation groove 19 is opened at one end of the second connecting rod 18. The end of the first connecting rod 17 away from the L-shaped connecting plate 14 is rotatably connected in the rotation groove 19. A rotating motor 20 is fixedly arranged on the side wall of the second connecting rod 18. The output shaft of the rotating motor 20 is coaxially fixedly connected to the rotating end of the first connecting rod 17. The end of the second connecting rod 18 away from the first connecting rod 17 is fixedly connected to a fixing frame 21, and the fixing frame 21 is fixedly connected to the unmanned aerial vehicle.

[0025] By means of the cooperation between the screw 16 and the threaded hole 13 and the fixing hole 15, the base 1 can be freely disassembled on the first connecting rod 17, so that the base 1 can be replaced easily. At the same time, after the camera is fixed on the base 1, by starting the rotating motor 20, the first connecting rod 17 can drive the base 1 to rotate together, thereby adjusting the shooting angle of the camera.

[0026] The above-mentioned arrangement is achieved by opening an installation groove 2 and a strip groove 3 on the base 1 along the length direction, and rotatably setting a bidirectional threaded rod 4 between the inner walls at both ends of the installation groove 2, symmetrically setting two nuts 5 on the bidirectional threaded rod 4, and fixing a fixing plate 7 above the two nuts 5 through a connecting block 6, and also providing a fixing motor 8 for driving the bidirectional threaded rod 4 on the side wall of the base 1. The camera to be fixed is placed on the base 1, and then the fixing motor 8 is started to clamp and fix the camera by the two fixing plates 7, so as to fix cameras of different specifications and sizes, thereby improving the practicality of the unmanned aerial vehicle airborne gimbal.

[0027] like Figure 1 , Figure 3 As shown, anti-skid pads 9 are fixedly arranged on the side walls of the two fixing plates 7 close to each other. The anti-skid pads 9 are made of anti-skid rubber material. Furthermore, a serrated groove 10 is opened in the vertical direction on the side wall of the anti-skid pad 9 away from the fixing plate 7.

[0028] By providing the anti-slip pad 9, the friction between the fixing plate 7 and the camera can be increased, thereby improving the stability of the camera fixation and thereby improving the safety of the unmanned aerial vehicle airborne gimbal. By providing the serrated groove 10, the friction between the fixing plate 7 and the camera can be further increased to ensure safety.

[0029] like Figure 3 As shown, a limiting groove 11 is provided on the side wall of the strip groove 3 along the length direction, and a limiting block 12 is arranged in the limiting groove 11 , and the limiting block 12 is fixedly connected to the side wall of the connecting block 6 .

[0030] Through the cooperation between the limiting groove 11 and the limiting block 12, the movement of the fixing plate 7 can be made more stable, thereby ensuring the fixing effect of the fixing plate 7 on the camera.

[0031] Working principle: When it is necessary to fix cameras of different sizes, place the camera to be fixed in the middle of the upper end surface of the base 1, and then start the fixing motor 8 to drive the bidirectional threaded rod 4 to rotate forward. Under the forward rotation of the bidirectional threaded rod 4, the two nuts 5 symmetrically arranged on the bidirectional threaded rod 4 are opened to move similarly, and then the two connecting blocks 6 are used to drive the two fixing plates 7 to move similarly, so as to achieve a clamping and fixing effect for the camera located in the middle. Through the cooperation of the screw 16 with the threaded hole 13 and the fixing hole 15, the base 1 can be freely disassembled on the first connecting rod 17, which is convenient for replacing the base 1. At the same time, after the camera is fixed on the base 1, by starting the rotating motor 20, the first connecting rod 17 can drive the base 1 to rotate together, thereby realizing the adjustment of the shooting angle of the camera.

[0032] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
