Description

Intelligent lock capable of replacing various mechanical lock panels Technical Field The invention relates to the technical field of door locks, in particular to an intelligent lock capable of replacing various mechanical lock panels. Background The prior mechanical door lock mainly comprises a mechanical lock body part and a panel part, wherein the panel is provided with a lock cylinder and a front handle, the front handle is used for controlling the movement of a latch bolt on the mechanical lock body, and the lock cylinder can drive the telescopic movement and the latch bolt movement of a latch bolt above the mechanical lock body. The existing intelligent lock (electronic lock) is divided into a semi-automatic lock body part, an electric control part and a panel part, wherein the semi-automatic lock body part mainly comprises a mechanical lock body part, the electric control part is arranged in the mechanical lock body and used for controlling the locking and unlocking of the square tongue, the panel part is provided with a front handle and a lock cylinder, the front handle is used for controlling the action of the inclined tongue, the lock cylinder is used as a backup (used when an electric control function fails), and at least the telescopic movement of the square tongue can be controlled. And the full-automatic intelligent lock panel part can be provided with no front handle or the front handle is fixed and used for pulling the door body to be closed. Because the mechanical lock body portion of the conventional mechanical door lock is different from that of the smart lock, when a user who installs the conventional mechanical door lock changes to the smart lock, it is replaced together with the mechanical lock body, resulting in waste. In addition, when the original lock body hole opening position on the door body is different from the changed intelligent lock hole opening position, the hole is required to be re-punched or the hole is formed after the original door body hole is repaired, the construction is troublesome, and the cost is high. Chinese patent No. CN202223574850.1 discloses a door lock structure in 2023, 10 months and 3 days, including preceding lock face-piece, lock core assembly, the knob, acrylic panel, mainboard subassembly and lock body, preceding lock face-piece top internally mounted has lock core assembly, the knob is installed to lock core assembly one side, the joint has acrylic panel in the preceding lock face-piece, acrylic panel one side laminating has the mainboard subassembly, preceding lock face-piece one side cooperation links up has the lock body, lock core assembly one end cooperation has cup jointed the clutch main part, the inside joint of clutch main part has clutch rotor, clutch main part bottom links up and has driven clutch, install the square post in the clutch rotor, clutch rotor and mainboard subassembly one side are connected with the bottom plate jointly, bottom plate one side parcel has the silica gel pad. The structure can be matched with mechanical lock bodies on some old door bodies to be used, so that the old lock bodies are changed into intelligent locks without replacement. However, the key cylinder assembly of this structure is provided on the knob (front handle), resulting in a large size of the knob, affecting the aesthetic appearance of the panel. In addition, the driving clutch with the structure is ejected out through the arc-shaped push rod at the top end of the driving clutch, is in ejection connection with the clutch main body, and ejects the clutch pin into the groove of the rotor, so that the clutch main body and the clutch rotor are integrated, the knob and the clutch rotor are in transmission connection, and unlocking or locking is realized by rotating the knob. The clutch pin is radially matched with the clutch main body and the clutch rotor, and the clutch pin is subjected to larger shearing force in the locking and unlocking process and is easy to break. In addition, the lock core (the true lock core which needs to be unlocked by a key) of the structure is matched with the clutch rotor, namely, when the lock is unlocked by the key, the lock core needs to be completely unlocked by the key, so that the lock core needs to be arranged at the position of the front shell, which is convenient for inserting the key and screwing, and the design of the front shell is limited. Simultaneously, the knob is unblanked and is locked and need drive the lock core simultaneously and rotate, and resistance is bigger. Disclosure of Invention The invention aims to provide an intelligent lock which has a simple and reasonable structure and a small volume and can replace various mechanical lock panels. The purpose of the invention is realized in the following way: The utility model provides an intelligent lock of interchangeable multiple mechanical lock panel, includes front panel, rear panel and intelligent identification card recognition control circuit, and
