Description

Technical Field

[0001] The present application relates to the technical field of smart locks, and in particular to a novel smart lock mechanical code disk unlocking structure. Background Art

[0002] Most existing smart locks use a mechanical lock core as their backup unlocking method. When the electronic unlocking method of the smart lock fails, the spare mechanical key can be used to twist the lock core to unlock the door. However, due to the long-term non-use of the spare mechanical key, users often put away the spare mechanical key, which leads to the loss of the spare mechanical key after a long period of non-use. At this time, if the electronic unlocking method of the smart lock fails and the spare mechanical key cannot be found, the door lock cannot be opened, and the lock core may even need to be destroyed in order to open the door lock, which greatly reduces the user experience.

[0003] Therefore, there is an urgent need for a backup unlocking method for smart locks to solve the defects existing in the use of the above-mentioned existing smart locks. Utility Model Content

[0004] The present application proposes a novel smart lock mechanical code disk unlocking structure, which adopts a code disk as a backup unlocking method. There is no need to carry or store a spare mechanical key, and there is no risk of losing the key. At the same time, the mechanical lock cylinder and the USB backup power supply are eliminated, which has the advantage of reducing the cost of using the smart lock in disguise. It is used to solve the existing smart lock unlocking method that uses a mechanical key as a backup. Because the spare mechanical key is not used for a long time, users often store the spare mechanical key, which leads to the phenomenon that the spare mechanical key is lost after a long period of non-use. At this time, if the electronic unlocking method of the smart lock fails and the spare mechanical key cannot be found, the door lock cannot be opened, and it is even necessary to destroy the lock cylinder in order to open the door lock, which greatly reduces the user experience.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a new type of smart lock mechanical code disk unlocking structure, including a lock shell, a motor is fixedly installed inside the lock shell, and a connecting rod is fixedly installed on the side of the lock shell and below the motor, a code disk is fixedly installed on the end of the lock shell, and the code disk and the motor are connected by a connecting rod transmission, and after the correct password is entered, the connecting rod connected to the motor can be pushed to move to trigger the push rod action on the motor.

[0006] Furthermore, the password disk includes an upper cover fixedly mounted on the end of the lock shell through a connecting rod, a lower shell is fixedly mounted on the other end of the upper cover, and a knob concave wheel is movably sleeved on one side of the interior of the lower shell, a knob fixedly connected to the knob concave wheel is provided on one side of the exterior of the lower shell, a connecting rod cam is movably connected to the other side of the knob concave wheel, the connecting rod cam is movably connected to the upper cover, and the connecting rod cam can only move along the direction of its central axis.

[0007] Furthermore, the upper and lower ends of one side of the outer surface of the connecting rod cam are milled flat and movably engaged with one side of the interior of the upper cover.

[0008] Furthermore, a first slope surface is provided on the end surface of the knob cam, and a second slope surface is provided on the corresponding end surface of the connecting rod cam, and the first slope surface and the second slope surface cooperate with each other.

[0009] Furthermore, a return spring is movably sleeved on the outer surface of the connecting rod cam, and a transmission connection is formed between the connecting rod cam and the upper cover via the return spring.

[0010] The utility model application has the following technical effects:

[0011] The present application provides a novel smart lock mechanical code disk unlocking structure. For the setting of the code disk and the structure thereon, a mechanical code lock can be used as a backup unlocking method of the smart lock. Compared with the existing mechanical spare key, this backup unlocking method does not require carrying or storing a spare key, thereby effectively avoiding the risk of losing the key. At the same time, a mechanical code disk is used instead of a mechanical lock core as the backup unlocking method of the smart lock, eliminating the problem of a mechanical lock core and a USB backup power supply, thereby reducing the use cost of the smart lock in disguise.
