Abstract: An unmanned aerial vehicle arm adjustment device for adjusting an unmanned aerial vehicle arm into a folding state or an extracting state with respect to a fuselage of the aerial vehicle includes: left and right curb plates connected to the fuselage; a rocking arm connected to the unmanned aerial vehicle arm, wherein one end of the rocking arm is articulated with the left and right curb plates, and a first engaging part is provided on the rocking arm; and a locking member articulated with the left and right curb plates, wherein the locking member is provided with a second engaging part for engaging with the first engaging part; wherein the locking member is adapted to rotate in a first direction to force the second engaging part to engage with the first engaging part so as to hold the rocking arm such that the unmanned aerial vehicle arm is in the extracting state; and wherein the locking member is adapted to rotate in a second direction opposite to the first direction to force the second engaging part to dis

Abstract: A connector, a built-in antenna structure, and an unmanned aerial vehicle using the built-in antenna structure. The unmanned aerial vehicle includes a body, and a support stand including a receiving rod. The built-in antenna structure includes a connector, a buffer and an antenna. The antenna and the buffer are received in the receiving rod, with the buffer wrapping the antenna. The connector is disposed between the receiving rod and the body to drive the receiving rod to rotate relative to the body. One end of the antenna protrudes from the connector and is electrically connected with the body. In an embodiment, the space occupied by the antenna is reduced, and the service life of the antenna and the overall appearance of the unmanned aerial vehicle are improved. Moreover, the angle of the receiving rod can be adjusted, for facilitating reception of signals by the antenna.

Abstract: A cradle head includes: a yaw support, wherein one end of the yaw support is rotatable around a yaw axis; a pitching support, which is rotatably connected to the yaw support via a pitching axis, wherein a camera device mounting seat is provided on the pitching support; a first casing attached on the pitching support, wherein a first accommodating space is provided within the first casing, wherein the camera device mounting seat is disposed within the first accommodating space, and wherein a camera hole is provided in the first casing; and a third casing, provided on the yaw support, wherein a third accommodating space is provided within the third casing, the yaw support being disposed within the third accommodating space; wherein the third casing and the first casing form a part of a curved outer surface of the cradle head.
