Abstract: An electric connector and a movable platform are provided. The electric connector includes a housing, a circuit board, and an electric connection part. The circuit board is arranged in the housing to connect to a load of the movable platform. The electric connection part is displaceable relative to the housing, and at least one portion of the electric connection part may extend out of the housing. A sealing ring may be provided in an outer peripheral surface of the electric connection part that extends outside the housing to seal the gap between the electric connection part and the casing of the movable platform, so as to isolate the circuit board of the housing. The electric connection part may be electrically connected to the circuit board and an external battery respectively to enable the circuit board to process electrical signals output from the battery.

Abstract: A lens limiting assembly includes a lens assembly ring and a locking ring arranged outside the lens assembly ring. The lens assembly ring includes an accommodating groove. The locking ring includes a body and a hook protruding inwardly from the body and accommodated in the accommodating groove.

Abstract: A lens limiting assembly includes an elastic element including an annular elastic body and an elastic arm extending from an inner side of the elastic body inward and downward along an axial direction, and a locking ring including a flange configured to abut against the elastic arm.

Abstract: An unmanned aerial vehicle (UAV) includes a heat dissipation device, an inertial measurement unit (IMU), and a control module. The heat dissipation device includes an air guiding cover and a heat conduction plate. The air guiding cover includes an air duct configured to guide an airflow, and the heat conduction plate directly constitutes a portion of a sidewall of the air duct. The IMU module is received within the air duct. The control module is located outside the air duct and disposed at a side of the heat conduction plate that faces away from the IMU module. Heat generated by the IMU module is taken away directly by the airflow within the air duct.

Abstract: A battery mounting structure for mounting a battery includes a housing. The housing includes a receiving groove configured to receive the battery. The receiving groove includes a groove bottom surface and a groove side wall connected with the groove bottom surface. The housing also includes a receiving space extending through the groove bottom surface and the groove side wall. A first position limiting member is provided on the housing. The first position limiting member is configured to detachably couple with the battery and to restrain the battery to move in a plane perpendicular to the groove bottom surface. The battery mounting structure also includes a second position limiting member provided on the housing. The second position limiting member includes a position limiting block and a button connected with one another and movable together with one another, the button being received in the housing and exposed from the housing.

Abstract: A lens limiting assembly includes an elastic element, a lens assembly ring arranged on the elastic element, and a locking ring arranged outside the lens assembly ring and configured to press a portion of the elastic element along an axial direction when the locking ring rotates in one direction.
