Abstract: The present disclosure provides a lock and a method and a system for controlling the lock. The lock may include an operation part, an action part, and a bolt. The action part may be configured to drive the bolt to move. The operation part and the action part may be connected to each other via a transmission connection. The transmission connection may be blockable.

Abstract: A stop device includes a first shift lever including a first shifting part configured to rotate around a rotation axis to form a first motion trajectory, and a second shift lever including a second shifting part partially within the first motion trajectory. The first shifting part drives the second shifting part to rotate around the axis of the rotating shaft to form a second motion trajectory. The stop device further includes a stopping boss located on a periphery of the first motion trajectory and partially within the second motion trajectory. The second shift lever rotates to drive the second shifting part to contact a first side of the stopping boss when rotating in a first direction and to contact a second side of the stopping boss facing away from the first boss when rotating in a second direction opposite to the first direction.

Abstract: A stop device includes a motor rotor assembly including a rotating shaft, a first shift lever fixedly connected to the rotating shaft and including a first shifting part configured to rotate around an axis of the rotating shaft to form a first motion trajectory, and a second shift lever rotatably connected to the first shift lever and including a second shifting part partially within the first motion trajectory. The first shifting part is configured to drive the second shifting part to rotate around the axis of the rotating shaft to form a second motion trajectory. The stop device further includes a motor stator assembly sleeved on the rotating shaft and rotatably connected with the rotating shaft. The motor stator assembly includes a stopping boss located on a periphery of the first motion trajectory and partially within the second motion trajectory.

Abstract: A quick gimbal connector comprises: a first cylinder comprising a sliding slot on an inner wall of a first end of the first cylinder, at least one entrance provided at an end portion of the sliding slot, and a first boss provided on the first cylinder; a second cylinder coaxially and rotatably connected with the first cylinder; a connector; at least one rib provided on the connector; and a connecting plate fixedly connected with the second cylinder and being provided with a second boss. The at least one rib is configured to fit with the at least one entrance and can enter into and exit from the sliding slot via the at least one entrance when the first boss abuts against the second boss, such that the first cylinder and the connector can be locked or separated.
