[0029] Reference Figures 1 to 3A simple electric lock according to an embodiment of this utility model includes: a mechanical lock cylinder 100, built into a door panel, the mechanical lock cylinder 100 including a lock shell 110, a fork 120 rotatably disposed on the lock shell 110, a core 130 connected to the fork 120, and an unlocking block 140; a lock body 200 for mounting and fixing on the inner surface of the door panel, the lock body 200 having a drive rod 300 rotatably disposed thereon, one end of the drive rod 300 extending out of the lock body 200 and engaging with the unlocking block 140; an electric drive mechanism 400 disposed on the lock body 200 and connected to the drive rod 300; and an identification control module disposed on the lock body 200 and electrically connected to the electric drive mechanism 400.

[0030] When a traditional door lock needs to be converted into an electric door lock, the mechanical lock cylinder 100 and bolt assembly of the traditional door lock can be retained. The lock body 200 is fixed to the inner surface of the door panel. The unlocking block 140 of the mechanical lock cylinder 100 is connected by the drive rod 300. After the user inputs the identity verification information into the identification control module, the electric drive mechanism 400 drives the drive rod 300 to rotate, thereby driving the bolt assembly to extend and retract. The structure is very simple, the conversion cost is low, and the operation is convenient during the conversion.

[0031] See Figure 1 and Figure 2 In some embodiments of this utility model, the lock case 110 includes a cylindrical portion 111 and an elongated plate portion 112 formed on the side of the cylindrical portion 111. The core 130, the fork 120, and the unlocking block 140 are all rotatably disposed on the cylindrical portion 111. The end of the unlocking block 140 is provided with a non-circular drive groove 141. The cross-sectional shape of one end of the drive rod 300 is adapted to the drive groove 141. The elongated plate portion 112 is connected and fixed to the lock body 200. It should be noted that the shape of the lock case 110 composed of the cylindrical portion 111 and the elongated plate portion 112 is a standardized shape. The drive groove 141 is generally a straight groove. One end of the drive rod 300 is inserted into the drive groove 141 to drive the unlocking block 140 to rotate, thereby driving the fork 120 to rotate. The connection and fixation between the elongated plate 112 and the lock body 200 achieves the fixation of the relative position between the lock body 200 and the mechanical lock cylinder 100, ensuring the stability and reliability of the transmission.

[0032] See Figure 2 and Figure 3In some embodiments of this utility model, the elongated plate portion 112 has a threaded hole 113 extending along its length on its end face facing the lock body 200. The lock body 200 has a mounting plate 500 at its end, and a fastening screw 600 matching the threaded hole 113 passes through the mounting plate 500. The mounting plate 500 has a contoured groove 510 matching the end face contours of the cylindrical portion 111 and the elongated plate portion 112. It is understood that the contoured groove 510 restricts the mechanical lock cylinder 100 from moving relative to the mounting plate 500 in a direction parallel to the mounting plate 500. The fastening screw 600 engaging with the threaded hole 113 prevents the mechanical lock cylinder 100 from moving away from the mounting plate 500 along the axial direction of the drive rod 300, thereby achieving accurate positioning between the lock body 200 and the mechanical lock cylinder 100.

[0033] See Figure 2 and Figure 3 In some embodiments of this utility model, the electric drive mechanism 400 includes a motor 410, a driving gear 420 on the output shaft of the motor 410, a driven gear 430 on the drive rod 300, and a reduction gear pair meshing between the driving gear 420 and the driven gear 430. The motor 410 is connected to a battery 700 electrically connected to the identification control module. The electric drive mechanism 400 has a simple structure, is easy to manufacture and assemble, and can transmit a large torque. Specifically, when the user inputs correct identity information to the identification control module, the battery 700 supplies power to the motor 410, which electrically drives the driving gear 420 to rotate, thereby driving the drive rod 300 on the driven gear 430 to rotate via the reduction gear pair.

[0034] See Figure 3 In some embodiments of this utility model, the lock body 200 is generally cylindrical, the drive rod 300 is arranged along the central axis of the lock body 200, the output shaft of the motor 410 is parallel to the drive rod 300 and located on the outer periphery of the lock body 200, and the reduction gear pair includes a plurality of coaxial gears 440 arranged at intervals around the circumference of the drive rod 300 and connected in sequence, with the smaller teeth of one coaxial gear 440 meshing with the larger teeth of another coaxial gear 440. This structural layout is beneficial for improving space utilization, helps to achieve a compact internal structure of the lock body 200, and realizes the miniaturization of the electric lock.

[0035] See Figure 1 and Figure 2In some embodiments of this utility model, the lock body 200 includes a fixed cylinder 210 and a movable cylinder 220 rotatably disposed about the fixed cylinder 210. The end of the drive rod 300 away from the unlocking block 140 is connected to the movable cylinder 220. It should be noted that when the battery 700 is out of power or when the electric drive mechanism 400 malfunctions, the user can unlock the door from inside by rotating the movable cylinder 220. Furthermore, it should be noted that the user can also unlock the door from outside by inserting a mechanical key into the core 130 and rotating it.

[0036] See Figure 2 In some embodiments of this utility model, the internal space of the fixed cylinder 210 and the internal space of the movable cylinder 220 together form a receiving cavity. The fixed cylinder 210 is provided with a partition 830 that divides the receiving cavity into a first receiving cavity 810 and a second receiving cavity 820. In order to realize the partitioned arrangement of components, avoid mutual interference, and facilitate maintenance, the driving gear 420, the reduction gear pair and the driven gear 430 are all located in the first receiving cavity 810, and the motor 410, the battery 700 and the circuit board of the identification control module are all located in the second receiving cavity 820. The output shaft of the motor 410 and the drive rod 300 are movably passed through the partition 830.

[0037] See Figure 2 In some embodiments of this utility model, the partition 830 is provided with a first bushing 831 in the first cavity 810, and the inner wall of the fixed cylinder 210 opposite to the partition 830 is provided with a second bushing 211 corresponding to the first bushing 831. The two ends of the rotating shaft of the coaxial gear 440 are respectively inserted into the corresponding first bushing 831 and second bushing 211. The coaxial gears 440 form a stepped arrangement along the axial direction of the drive rod 300, which is beneficial to the stable rotation of the coaxial gears 440 and also to further reduce the space required for the first cavity 810.

[0038] See Figure 2 and Figure 3 In some embodiments of this utility model, a bracket 900 located within the second cavity 820 is fixedly disposed on the partition 830. The bracket 900 has at least two battery slots 910 and a positioning groove 920 for positioning the motor 410. The positioning groove 920 and the battery slots 910 are circumferentially distributed at intervals around the axial direction of the drive rod 300. This structural layout helps to reduce the space required for the second cavity 820, thereby reducing the overall size of the lock body 200. In this embodiment, the bracket 900 also has a mounting groove for positioning and fixing the circuit board of the identification control module.

[0039] In some embodiments of this utility model, the identification control module is a fingerprint recognition module or access control device disposed on the outer surface of the door panel. Users can unlock the door by pressing their fingerprint or swiping a card, which is very convenient. Of course, in other embodiments, the identification control module can also be a Bluetooth module, allowing users to control the electric drive mechanism 400 via Bluetooth using a mobile terminal such as a smartphone.

[0040] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
