Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicle (UAV) gimbals, in particular to a quick disassembly and assembly mechanism for an UAV gimbal. Background Art

[0002] Due to the diverse functions and uses of drones, various sensors or cameras are often mounted on the gimbal, so the gimbal can be designed with different structures as needed. Due to the limitations of the drone's payload capacity, it is usually required to reduce the weight and size of the gimbal structure while ensuring its normal operation. The stability of the gimbal's structure is a key indicator of its performance, directly affecting its image stabilization. A reasonably stable gimbal structure plays a vital role in improving the drone's operational performance.

[0003] The existing technology usually screws the gimbal directly into a bracket with a threaded groove inside. However, the motor drives the propeller to cut through the air to generate lift. When the propeller rotation axis is inconsistent with the motor rotation axis, vibration will occur. The vibration can easily cause the connection to loosen and even cause the gimbal to fall off, thereby damaging the camera and reducing the practicality of the device. Summary of the Invention

[0004] The purpose of the utility model is to provide a quick disassembly and assembly mechanism for a drone gimbal, which can issue an alarm when the gimbal and the connection are loose and can still keep the gimbal stable in a short time, thereby improving the practicality of the utility model and making the gimbal more stable.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: to provide a quick disassembly and assembly mechanism of a drone gimbal, including a fixing mechanism, the fixing mechanism including a second connecting plate, the lower surface of the second connecting plate is provided with a first through hole, the interior of the first through hole is provided with a protective mechanism, the protective mechanism including a first elastic ring, the right side surface of the first elastic ring is in contact with the inner wall of the first through hole, the right side surface of the first elastic ring is provided with a threaded rod, the upper surface of the first elastic ring is fixedly connected to the second elastic ring, the upper surface of the second elastic ring is provided with a fourth groove, the inner wall of the fourth groove is fixedly connected to the control switch, the upper surface of the second connecting plate is provided with a connecting mechanism, the connecting mechanism includes a threaded cover, the lower surface of the threaded cover is fixedly connected to the upper surface of the second connecting plate, and the interior of the threaded cover is provided with a connecting ring.

[0006] Optionally, the fixing mechanism includes a first connecting plate, a drone is mounted on the upper surface of the first connecting plate, a first damper is fixedly connected to the lower surface of the first connecting plate, and an end of the first damper is fixedly connected to the upper surface of the second connecting plate.

[0007] Optionally, a first groove is provided on the upper surface of the first connecting plate, and a shock-absorbing mechanism is installed on the inner wall of the first groove. The shock-absorbing mechanism includes an elastic block, and the elastic block is installed inside the first groove. The lower surface of the elastic block is fixedly connected to the first connecting block, and the lower surface of the first connecting block is fixedly connected to the first connecting rod.

[0008] Optionally, a second groove is formed on the lower surface of the second connecting plate, a second connecting block is movably connected to the inner wall of the second groove, and an upper surface of the second connecting block is fixedly connected to the bottom of the first connecting rod.

[0009] Optionally, a second connecting rod is fixedly connected to the inner wall of the connecting ring, the second connecting rod is located inside the first through hole, and a third groove is provided on the upper surface of the first elastic ring, and the surface of the third groove fits with the lower surface of the second elastic ring.

[0010] Optionally, a rotating mechanism is installed on the lower surface of the second connecting rod, and the rotating mechanism includes a bracket, a surface of the bracket is fixedly connected to a third connecting block, the right surface of the third connecting block is fixedly connected to a second damper, and the upper surface of the bracket is fixedly connected to a rotating shaft.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The utility model is provided with a threaded cover, a first elastic ring, and a second elastic ring. During use, the connecting ring fixed on the surface of the second connecting rod is screwed into the threaded cover to secure the gimbal. When the utility model vibrates during flight, causing the connecting ring to detach from the threaded cover for a while, the connecting ring will fall a certain distance, and the lower surface of the connecting ring will contact the upper surface of the second elastic ring. Due to the elasticity of the second elastic ring, it will be compressed. A control switch is installed inside the fourth groove of the second elastic ring. When the control switch is pressed, it transmits data to the drone above, and the staff will receive a warning signal. At this time, the control switch below the second elastic ring can still provide support for the connecting ring, so that the gimbal will not fall for a short time. During use, the utility model can issue an alarm when the gimbal and the connection are loose, and can maintain the stability of the gimbal for a short time, thereby improving the practicality of the utility model.

[0013] The utility model is provided with a first damper, an elastic block and a first connecting rod. When in use, the first connecting rod passes through the second connecting plate, so that the first connecting plate and the second connecting plate are connected in series. One end of the first connecting rod is fixedly connected to the first connecting block and the elastic block, and the other end is fixed to the second connecting block. Both are movably connected. Therefore, when vibration occurs, the vibration can be reduced by slightly changing the distance between the first connecting plate and the second connecting plate. The damper fixedly connected between the first connecting plate and the second connecting plate can also further reduce the vibration, making the gimbal more stable.
