Description

Technical Field

[0001] The present invention relates to an intelligent lock and an emergency opening method thereof. Background Art

[0002] Currently, common intelligent locks are mostly fingerprint locks and password locks. For general locks, when an electronic failure occurs in a fingerprint lock, the password lock can be used for mechanical opening. However, if the password is forgotten, it will be rather troublesome and the key needs to be used for opening. But the key is not always carried, which brings certain inconvenience to users, making it impossible to open the door lock in time. Moreover, always carrying the key is very inconvenient. Now, many intelligent locks tend to have no physical key and use the password lock for mechanical opening. Locks like this that combine an electronic fingerprint lock and a mechanical password lock are very popular. Usually, the lock is opened by fingerprint. In case it cannot be opened by fingerprint, it can still be opened mechanically through the password lock. However, if the password is forgotten, it will be troublesome. Summary of the Invention

[0003] In view of the problems pointed out in the background art, the present invention provides an intelligent lock and an emergency opening method thereof. In the case of forgetting the password, the unlocking password can be obtained by scanning a two-dimensional code, thus completely getting rid of the use of the key.

[0004] The technical solution of the present invention is realized as follows:

[0005] An intelligent lock includes a lock body. In the middle of the front side of the lock body, an intermediate installation groove is formed. An intermediate cover plate for covering the intermediate installation groove is provided on the intermediate installation groove. A groove is provided below the intermediate installation groove. A two-dimensional code is printed at the bottom of the groove. A protective sheet adapted to the groove is arranged in the groove. The protective sheet is circular and is rotatably arranged. A connection hole is provided at the center of the groove. A central rotating shaft connected to the connection hole is provided on the protective sheet. A circumferential limiting groove is provided on the side wall of the connection hole. A limiting protrusion cooperating with the limiting groove is provided on the central rotating shaft. Half of the area of the protective sheet is transparent, and the other half of the area is non-transparent. The two-dimensional code is arranged corresponding to half of the area of the protective sheet. The protective sheet is spaced from the bottom of the groove. Friction convex grains are provided on the outer surface of the protective sheet, and the friction convex grains are arranged corresponding to the non-transparent area of the protective sheet.
