Abstract
Claims
1. A smart door lock structure that can replace an existing spherical lock, comprising: a lock body unit disposed on a door panel, and including an outer module and an inner module; an image monitoring module disposed on the outer module, including a camera element and an infrared sensing element; a human body sensing module disposed on the outer module and adjacent to the image monitoring module, for triggering the image monitoring module when human movement is detected in front of the door panel; a communication module disposed on the outer module and electrically connected to the image monitoring module for data transmission; and a multi-unlocking module disposed within the lock body unit, including a fingerprint recognition device, a password input device, a card sensing device, a mechanical key device, a Bluetooth communication device, and a near-field communication sensing device, for the lock body unit to generate an unlocking action; A control module is located within the lock body unit and is electrically connected to the image monitoring module, the human body sensing module, the communication module, and the multi-unlocking module to integrate control of door lock opening, image monitoring, and communication operations; and a power module is located within the lock body unit and is electrically connected to the aforementioned modules to provide power.
2. The smart door lock structure that can replace the existing spherical lock as described in claim 1, wherein the camera element of the image monitoring module is a high-resolution camera device and has infrared night vision function.
3. A smart door lock structure that can replace an existing spherical lock as described in claim 1, wherein the human body sensing module is a passive infrared (PIR) sensor.
4. A smart door lock structure that can replace the existing spherical lock as described in Request 1, wherein the communication module has cloud connectivity for remote data access and management.
5. A smart lock structure that can replace the existing spherical lock as described in claim 1, wherein the password input device has a decoy password input mechanism to prevent the password from being spied on.
6. The smart door lock structure that can replace the existing spherical lock as described in claim 1, wherein the communication module further supports real-time image transmission and two-way voice communication functions, and can transmit the real-time image of the intercom screen to the user's mobile device so that the user can communicate with visitors outside the door through the mobile device.
7. The smart door lock structure that can replace the existing spherical lock as described in Request 1, wherein the communication module is connected to a mobile device and performs remote unlocking, access permission setting and door opening record query through an application.
8. The smart door lock structure that can replace the existing spherical lock as described in claim 1, wherein the power module includes a Type-C emergency power supply device and a magnetic wireless charging device.
9. A smart door lock structure that can replace an existing spherical lock as described in claim 1, wherein the lock body unit includes a bolt located inside the door panel and coaxially assembled with an outer module and an inner module; the bolt has a lock cylinder and a door edge, the door edge having a retractable latch; the outer module has an outer lock body and an outer assembly element, the inner module has an inner lock body and an inner assembly element, the outer lock body has an outer handle, the inner lock body has an inner handle, the outer handle and the inner handle are linked to the lock cylinder to drive the latch to extend or retract; wherein the distance from the lock cylinder to the door edge forms a center distance with a length of 60 mm to 70 mm.
