Abstract: A unmanned aerial vehicle may include a fuselage body, a top lens structure at a top of the fuselage body, the top lens structure protruding from the top of the fuselage body; and a bottom lens module at a bottom of the fuselage body, the bottom lens module protruding from the bottom of the fuselage body.

Abstract: The present disclosure provides a lampshade structure, an unmanned aerial vehicle (UAV) arm, a UAV, and a movable platform. The lampshade structure may comprise a first light-transmitting surface of a lampshade body close to a light-emitting element and a second light-transmitting surface of the lampshade body away from the light-emitting element; wherein the first light-transmitting surface may include a scattering structure to outwardly refract light emitted by the light-emitting element to expand a light-emitting angle and an irradiation direction of the light-emitting element, thereby obtaining sufficient light in a desired direction.

Abstract: A control assembly and an aircraft include a bearing board, a central board, a flight control board, a shock absorbing unit, and a communication connection cable. The flight control board is mounted on the central board. The central board is connected to the bearing board via the shock absorbing unit. Therefore, the flight control board and the central board form a whole for shock absorption through the shock absorbing unit.

Abstract: A foldable and retractable mechanism includes a first body and a second body. The first body includes a first connection member. The second body is configured to rotate relative to the first body and including a second connection member. The first connection member and the second connection member are assembled in movable manner. The first connection member and the second connection member are configured to be in a retracted state, in which the first connection member and the second connection member at least partially overlap with each other and constraint relative rotation of the first body and the second body. The first connection member and the second connection member are configured to be in an extended state, in which the first connection member is away from the second connection member, and the second body is rotatable and capable of being folded over the first body.
