Description

Technical Field

[0001] The utility model relates to the technical field of door locks, in particular to an embedded intelligent door lock. Background Art

[0002] As we all know, smart door locks are improved from traditional mechanical locks and are more intelligent and simple in terms of user security, identification, and management. Smart door locks are the executive components of door locks in access control systems. Smart door locks are composite locks that are safe, convenient, and have advanced technology, so they are widely used.

[0003] For example, Chinese utility model patent CN202120792361.X discloses a durable smart door lock, the main structure of which is: a smart door lock body, a sensing bar is provided on the smart door lock body, the sensing bar has a frame hole, a glass embedded in the frame hole, and a moisture-proof film adhered to the surface of the glass;

[0004] A main control unit, which is arranged in the main body of the smart door lock, and the main control unit includes a main control chip, and a battery electrically connected to the main control chip and used to power the smart door lock; a sensing unit, which is installed in the sensing column and electrically connected to the main control unit, and the sensing unit includes a distance sensor for sensing the distance between the human body and the smart door lock to control the opening and closing of the battery power supply circuit; although the above-mentioned smart door lock can realize multiple modes of smart switch lock, its door handle and the smart door lock body are exposed outside the door. When lawless elements or children deliberately damage the exposed smart door lock body, it will cause great losses to the user. At the same time, dust or water will enter the exposed smart door lock body, causing the user's mechanical unlocking failure and unable to open the door. In addition, the exposed smart door lock body protrudes more from the flat door body surface and is of lower grade. Therefore, the defects of the above-mentioned existing smart door locks are very obvious. For this reason, we propose an embedded smart door lock to solve the above problems. Utility Model Content
