A smart door lock reset structure

Technical Field

The utility model relates to the technical field of intelligent door locks, and in particular to an intelligent door lock resetting structure.

Background Art

With the development of science and technology, door locks have evolved from traditional purely mechanical locks to integrated intelligent locks. Intelligent door locks are improved on the basis of traditional mechanical locks. They are composite locks that are more intelligent and simple in terms of user security, identification, and management. They are the executive components of door locks in access control systems.

Smart door locks are becoming more convenient and more secure, and have become a hot-selling product on the market, loved by consumers. However, there is also the problem that smart door locks cannot be opened indoors due to electronic failures. In order to ensure that smart door locks can still be opened indoors when electronic failures occur, the design requirements for fully automatic smart door locks require a one-button escape function, that is, there must be an emergency unlocking mechanical structure on the indoor side of the door lock, which can quickly open the door when the electronic function fails.

At present, the smart door locks on the market mainly use handles or knobs to achieve the one-button escape function. The handle structure is generally complex, requires more materials, resulting in high costs, and requires a lot of force to open the door by skipping the normal unlocking steps; the existing knob structure usually uses a retaining spring to fix the knob, which will cause a large gap between the knob and the door lock body, and the knob will be loose under the door lock body, resulting in failure of quick reset unlocking, increasing the instability of emergency unlocking, or using a complex structure to increase stability, but there will be problems with difficulty in disassembly and assembly.
