Abstract

The invention discloses a dual-power lockset. The dual-power lockset comprises a lock shell and a lock tongue arranged on the lock shell. A dual-motor planetary gear driving mechanism is arranged in the lock shell. The dual-motor planetary gear driving mechanism comprises a first motor, a second motor, an installing frame, a planetary gear set, a gun gear, an outer gear ring and an output part. Both the sun gear and the planetary gear set are arranged in the outer gear ring, and the planetary gear set is arranged in a manner that the sun gear is surrounded by the planetary gear set. Meshing isformed between each planetary gear in the planetary gear set and the sun gear and the outer gear ring correspondingly. The output end of the first motor is in meshing linkage with the sun gear. The output end of the second motor is meshing linkage with the outer gear ring. Each planetary gear of the planetary gear set is rotatably installed and arranged on the output part through rotary pins correspondingly. Linkage cooperation is formed by the output part and the lock tongue through a linkage mechanism. According to the dual-power lockset, because a clutch structure is not needed to be arranged between the two motors, the structure is effectively simplified, and in addition, reliability of operation is also improved greatly.

Description

technical field

[0001] The invention relates to a lock, in particular to a double power lock. Background technique

[0002] At present, with the development of intelligent locks, most of the existing door locks use motors as the power source to realize the opening and closing of the door locks. The structure of the drive means that there are two motors inside the door lock. Under normal circumstances, as long as one motor is working, the switch of the door lock can be realized, and the other motor is used as a backup motor. However, in order to realize the mutual switching of the two motors and avoid interference between the two motors during work, the prior art usually arranges a corresponding clutch structure between the two motors, which not only causes the structure of the driving part to be complicated, but also due to many step clutch operation, thereby reducing the reliability of the operation.
