Description

Technical Field

[0001] The utility model relates to the technical field of electronic locks, and more specifically to an electronic lock driving structure. Background Art

[0002] Electronic door locks are locks that use programmable memory and data reading devices, and their keys are difficult to copy. The key contains a special electronic chip, usually 3.5×3.5mm, which stores a specific password. When the key is inserted into the keyhole, the password is sent to the memory in the lock, and a magnetic field is generated at the same time, and a voltage is generated in the coil on the chip, which is used as a power source for unlocking the lock. If the password in the key matches the lock, the lock will be opened. With the development, electronic locks have gradually developed into multiple categories, such as password locks, fingerprint locks, radio frequency identification locks, etc.

[0003] The shortcomings of the existing technology: However, most of the existing electronic locks rely on the rotation of several gears to drive the movement of other accessories to control the opening and closing of the lock. However, the rotation of the gears does not have a self-locking function, which makes it possible for the electronic lock to be pried open, and the security is not high. At the same time, most electronic locks have complex internal structures. Once an abnormality occurs in an internal component, the entire lock may be unable to be unlocked. For this reason, we propose an electronic lock drive structure. Utility Model Content

[0004] In order to overcome the above defects of the prior art, the utility model provides an electronic lock driving structure to solve the problems existing in the above background technology.

[0005] The utility model provides the following technical solutions: an electronic lock driving structure, comprising a metal protective shell group, the metal protective shell group comprising an assembly shell and an internal base, a surface layer of the assembly shell is provided with a rectangular notch, the rectangular notch is fixedly connected with an inductive driving mechanism, one end of the inductive driving mechanism is fixedly connected with a tooth plate, the tooth plate is meshingly connected with a bolt mechanism, the bolt mechanism comprises a plug plate, the plug plate is slidably connected to the assembly shell, a self-locking mechanism is movably connected to the internal base, the self-locking mechanism comprises a driving plate, the driving plate is slidably connected to the internal base, and a signal transmission component is fixedly connected to the inner cavity of the assembly shell.

[0006] Preferably, an internal base is fixedly connected to the bottom surface of the inner cavity of the assembly shell, and a plurality of sliding holes are opened on one side of the assembly shell, and the sliding holes are slidably connected to the gate bolt mechanism.

[0007] Preferably, one end of the induction drive mechanism is fixedly connected to an induction detection plate, one side of the induction detection plate is fixedly connected to a drive motor, one end of the drive motor is fixedly connected to a drive shaft, and one end of the drive shaft is fixedly connected to a gear plate.

[0008] Preferably, a toothed gate plate is fixedly connected to one side of the gate bolt mechanism, a tooth groove is opened on one side of the toothed gate plate, the tooth groove is meshingly connected to the toothed plate, one end of the toothed gate plate is fixedly connected to the plug plate 303, a linkage plate is fixedly connected to one side of the toothed gate plate, and an induction plug is fixedly connected to the linkage plate.

[0009] Preferably, one end of the self-locking mechanism is fixedly connected to a signal motor, one end of the signal motor is fixedly connected to a threaded drive rod, the rod body of the threaded drive rod is threadedly connected to a drive plate, and one end of the top surface of the drive plate is fixedly connected to a triangular clamping block.

[0010] Preferably, the signal transmission component has one end fixedly connected to a signal transmitter, and one side of the signal transmitter is fixedly connected to a docking device.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model is provided with a self-locking mechanism through a metal protective shell group. When the induction detection plate detects the card key, the signal is transmitted to the driving motor, the driving motor drives the driving shaft to rotate and then synchronously drives the tooth plate to rotate, and the tooth plate drives the gate bolt mechanism to slide to one side until the plug plate is inserted into the lock hole, forming a locked state. At this time, the induction plug is successfully docked with the slot on the docking device, and the signal transmitter connected to the docking device transmits the connection signal to the signal motor. At this time, the signal motor starts to drive the driving threaded rod to rotate, and the driving plate threadedly connected thereto rises synchronously and approaches the plug plate on one side of the linkage plate until the triangular card block is engaged with the triangular protrusion on the bottom surface of the plug plate. At this time, the gate bolt mechanism is locked. The setting of the self-locking mechanism eliminates the possibility of prying the gate bolt mechanism to unlock the door by abnormal unlocking means, greatly improving the safety of the electronic lock itself and ensuring the safety of the householder.

[0013] 2. The utility model is provided with an inductive drive mechanism, a gate bolt mechanism, a self-locking mechanism and a signal transmission component through a metal protective shell group. Through the streamlined structures, the correct signal of the card key is given to the inductive detection board, so that it starts several components related to the driving motor to drive the gate bolt mechanism, and then the electronic lock is locked by the gate bolt mechanism, and after locking, the self-locking mechanism is started by connecting the inductive plug with the docking device to complete the secondary locking. Since the structure is relatively streamlined and there are no overly complicated parts inside, as long as the bolt plate completes the locking, the self-locking mechanism will be started unconditionally, which greatly reduces the situation where the lock cannot be opened due to damage of other components.

As the bolt plate 303 slides out of the sliding hole opened on the assembly shell 101, the electronic lock is locked. At this time, the sensing component on the gate bolt mechanism 3 docks with the signal transmission component 5 and transmits the secondary locking signal to the self-locking mechanism 4. The driving plate 403 begins to rise in cooperation with the sliding groove opened in the built-in base 102, approaches the triangular protrusion on the bottom surface of the bolt plate 303, and then abuts against one side of the triangular protrusion to complete the secondary locking.

[0022] Furthermore, the inner bottom surface of the inner cavity of the assembly shell 101 is fixedly connected with an inner base 102 , and one side of the assembly shell 101 is provided with a plurality of sliding holes, which are slidably connected with the gate bolt mechanism 3 .

As the plug plate 303 slides out of the sliding hole opened on the assembly shell 101, and the locking of the electronic lock is completed, at this time, the induction plug 304 on the gate bolt mechanism 3 is docked with the induction slot opened on the docking device 502. After the signal transmitter 501 connected to the docking device 502 receives the signal of completion of docking, it sends a start signal to the self-locking mechanism 4. After receiving the start signal, the signal motor 401 immediately starts and synchronously drives the threaded driving rod 402 to rotate, further drives the driving plate 403 connected thereto, and begins to cooperate with the sliding slot opened in the built-in base 102 to rise, close to the triangular protrusion on the bottom surface of the plug plate 303, and then abuts against one side of the triangular protrusion to complete the secondary locking.
