  • Patent number: 11905739
    Abstract: A manual/automatic dual-purpose clutching structure includes a driving gear assembly, a reversing clutching assembly and a driven gear assembly. The driving gear assembly includes a first gear, a second gear and a driving module, the first gear being coaxially and fixedly connected to the second gear. The reversing clutching assembly includes a reversing gear and a reset spring, the reversing gear is located on one side of and meshes with the second gear. The driven gear assembly includes an output gear which is located on the other side of and does not make contact with the second gear. The reversing gear rotates around a central axis of the second gear under a driving of the driving module to mesh with the output gear. After power of the driving module disappears, the reversing gear is prompted to be disengaged from the output gear under an action of the reset spring.

  • Publication number: 20230383572
    Abstract: A lock includes a lock housing, a cylinder assembly rotatably arranged in the lock housing and a locking keyless assembly connected to the cylinder assembly in a transmission way. The cylinder assembly includes a cylinder core and a tailpiece unit, a first clutch mechanism is provided between the cylinder core and the tailpiece unit, and a second clutch mechanism is provided between the locking keyless assembly and the tailpiece unit. When the second clutch mechanism is engaged, the locking keyless assembly is movable relative to the lock housing in a first direction under a driving of an external force for locking, and the cylinder core and the tailpiece unit rotate along with the locking keyless assembly. When the external force on the locking keyless assembly is withdrawn, the locking keyless assembly moves in an opposite second direction opposite, so that the second clutch mechanism switches to a disengaged state.

  • Patent number: 11781340
    Abstract: A locking device comprises a latch, a spindle and a rotary assembly. The latch is fixed to an object to be locked for engaging with a bore of a strike; the latch has a bolt which locks the object. One end of the spindle is detachably connected to the latch to drive the bolt to move towards or away from the bore. The rotary assembly is disposed at the other end of the spindle, which comprises a cylinder body and a rotary body, the cylinder body is rotated by the rotary body as it rotates, wherein one end of the rotary assembly is provided with a spindle driving means engaged with the other end of the spindle to drive the spindle to rotate. The rotary assembly drives the spindle to rotate via the spindle driving means, and the spindle drives the bolt to move approaching the bore to realize locking.

  • Publication number: 20230212884
    Abstract: The present disclosure provides a lock with a clutch driving mechanism, comprising a driving input portion, a dutch component, a dead bolt driving component, a latch bolt driving component, a first end of the driving input portion is driven, and the second end is connected to the clutch component; a first end of the dutch component is driven, a second end drive one of the dead bolt driving component and the latch bolt driving component, a first end of the latch bolt driving component is driven in the second direction, a second end opens the door. The mechanism can simply realize the keyless mechanical double locking of the dead bolt while the latch bolt still remains in the normally open mode without using the key every time when locking the dead bolt, that key or motor drive is used only when the dead bolt double locking is to be released.

  • Publication number: 20230147135
    Abstract: A dead-locking control mechanism for a door lock includes: a lock body; a fixing assembly; a rotatable spindle assembly having a first end rotatably connected with the fixing assembly and a second end in torque transmission connection with the bolt of the lock body, such that the bolt is drivable to extend beyond or retract into the fixed object; and a dead-locking control assembly including a stopping member arranged at the first end of the spindle assembly. The stopping member is movable between first and second positions relative to the spindle assembly, wherein in the first position, a first end of the stopping member is engaged with the fixing assembly and locked relative to the fixing assembly to thereby prevent the spindle assembly from rotating, and wherein in the second position, the stopping member is released from fixing assembly and thus the spindle assembly is capable of rotation freely.
