Abstract
A modularized electric door lock includes an operating device mounted to a door, an outer electric device mounted to an outer side of the door for receiving an unlocking signal, and an inner electric device mounted to an inner side of the door and controlling the outer electric device. The inner electric device includes an electric driving device mounted in the operating device for setting the operating device to a locked state or an unlocked state. The outer electric device and the corresponding inner electric device can be selected among various types, such that the door lock of a desired type can be rapidly assembled.
Claims18
A modularized electric door comprising:
- an operating device including an inner unit having an inner spindle and an outer unit having an outer spindle, with the operating device configured to be set to a locked state or an unlocked state;
- an electric driving device operatively connected to the operating device, with the electric driving device operable to set the operating device to the locked state or the unlocked state;
- a latch operatively connected to the inner spindle and the outer spindle of the operating device, with the operating device actuating the latch to move between a latching position and an unlatching position;
- an inner operating member coupled to the inner spindle, wherein operation of the inner operating member actuates the inner spindle to move the latch between the latching position and the unlatching position;
- an outer operating member coupled to the outer spindle, wherein when the operating device is set to the unlocked state, operation of the outer operating member actuates the outer spindle to move the latch between the latching position and the unlatching position, and wherein when the operating device is set to the locked state, operation of the outer operating member does not actuate the operating device to move the latch from the latching position to the unlatching position;
- an inner assembling portion coupled to the inner unit of the operating device;
- an inner electric device detachably coupled to the inner assembling portion and detachably and electrically connected to the electric driving device;
- an outer assembling portion coupled to the outer unit of the operating device;
- an outer electric device detachably and electrically connected to the inner electric device and configured to input unlocking information to the inner electric device, with the outer electric device detachably coupled to the outer assembling portion;
- and
- a power supply detachably and electrically connected to the inner electric device,
- with the inner assembling portion including an inner fixing member non-rotatably mounted to the inner unit of the operating device, with the inner electric device detachably coupled to the inner fixing member, with the inner assembling portion further including an inner cover having a through-hole and a mounting portion spaced from the through-hole, with the inner operating member extending through the through-hole of the inner cover, with the mounting portion including an engagement side, with the power supply including at least one hook on a side thereof, and with the at least one hook of the power supply detachably coupled to the engagement side of the mounting portion,
- with the inner cover further including a receptacle, with the power supply further including a coupling groove aligned with the receptacle, with the power supply further including a through-hole extending from an outer surface thereof to the coupling groove, with the modularized electric door lock further comprising:
- an engagement button slideably mounted in the receptacle, with the engagement button movable along a central axis of the receptacle between a front position partially outside of the receptacle and a rear position retracted into the receptacle, wherein the engagement button in the front position engages with the coupling groove of the power supply to prevent the power supply from disengaging from the inner cover, and wherein the engagement button in the rear position disengages from the coupling groove of the power supply to permit disengagement of the power supply from the inner cover,
- with the power supply engaged with the inner cover, the power supply is electrically connected to the inner electric device, and
- with the power supply disengaged from the inner cover, the power supply is not electrically connected to the inner electric device.
