Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the related art, when the intelligent lock performs unlocking action, firstly, the access authority of a user is verified through a password or a combination of the password and a biological recognition means, and when the user has the access authority, an electric control mechanical structure in the intelligent lock can automatically drive the lock tongue to leave a lock hole, so that the unlocking action is completed.

Because the intelligent lock is generally installed on the door, the door is not directly connected to the power supply in the common household design, so the intelligent lock is generally powered by the built-in power supply, when the electric quantity of the built-in power supply is exhausted and the unlocking can not be realized through the electric control mechanical structure, a user needs to rely on a mechanical key to unlock, under the condition that the correct mechanical key is inserted into the traditional lock cylinder 200, the lock liner 202 of the lock cylinder 200 can be separated from the lock shell 201 to rotate independently, and the transmission bar 600 rotates along with the rotation of the lock cylinder 200, so that the lock tongue is driven to leave the lock hole, and the unlocking action is completed.

In the above related art, when the electric quantity of the built-in power supply of the intelligent lock of the user is exhausted, the user needs to rely on a mechanical key to unlock, but the user can carry the mechanical key with him rarely after the intelligent lock is put into use, so that the unlocking cannot be performed in time, and great inconvenience is caused, so that a standby power supply is arranged on some intelligent locks of the related art, and the standby power supply supplies power to the electric control mechanical structure when the electric quantity of the main power supply is exhausted, so as to continue the unlocking work. However, in such related technologies, if the intelligent lock fails in the electric control system or the related mechanical structure is damaged, the user can only complete the door opening action by detaching the lock or violently unlocking if the user does not carry the mechanical key, which is time-consuming and labor-consuming and causes waste.
