[0001] The invention relates to the technical field of locks, in particular to a novel intelligent door lock. Background Art

[0002] The smart door lock in the prior art generally has a fingerprint module and a password key module on the front lock shell. The user needs to perform fingerprint verification or password verification before holding the front handle to turn the lock. This smart door lock has the following problems:

[0003] 1. Due to the operating distance between the fingerprint module and the password button module and the front handle, it takes a long time for the user to unlock the door. After the motor drives the door to unlock, it needs to set a long time for delay before it can automatically reset, which has low security.

[0004] 2. Since the fingerprint module and password key module are arranged on the front lock shell, and the lock body assembly is also arranged in the front lock shell, the volume of the front lock shell is relatively large. The front lock shell in the prior art is generally rectangular, so that the fingerprint module, password key module and lock body assembly have reasonable space to be distributed in the longitudinal direction.
