[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) gimbals, in particular to a self-stabilizing device for a UAV gimbal support arm. [Background technology]

[0002] The drone gimbal equipment is used in conjunction with the drone. When working, as the drone's propeller rotates at high speed, the drone gimbal is always working under high-frequency vibration; the support arm serves as a three-axis (pitch axis, roll axis and heading axis) connecting bridge. While ensuring the rigidity of this part, the mass production and cost of the part must also be considered to ensure that high-quality photos and videos are taken during the drone flight.

[0003] At present, the mainstream design on the market is "L" shaped, which is only fixed by two machine screws. This design has two major defects: 1. It cannot be completely tightened by machine screws, and there will still be slight looseness; 2. During the operation of the drone, high-frequency vibration will aggravate the looseness of the screws and support arms, resulting in poor recording effect. [Contents of the utility model]

[0007] Preferably, a rubber ring installation groove is formed on the side of the inner nesting end, and the rubber ring is sleeved in the rubber ring installation groove.

[0008] Preferably, a support arm fixing hole is provided on the inner nesting end, and a casing fixing hole is provided on the roll axis casing and the pan axis casing respectively, and the casing fixing hole corresponds to the support arm fixing hole for locking with a countersunk screw.

[0009] Preferably, a single-sided gap is formed between the outer side wall of the inner nesting end and the inner side wall of the nesting groove in the rolling shaft housing.

[0010] Preferably, a single-sided gap is formed between the outer side wall of the inner nesting end and the inner side wall of the nesting groove in the panning axis housing.

[0011] Preferably, the width of the single-side gap is 0.03 mm.

[0012] Preferably, the countersunk screw is glued with high-strength screw glue.

[0013] Preferably, the high-strength screw glue is compressed oxygen glue, model K-0271.
