These permanent magnets are usually fixed on the rotor, and multiple windings are arranged on the stator; when the permanent magnet rotor rotates, the magnetic field around it also changes. According to Faraday's law of electromagnetic induction, the changing magnetic field will induce voltage in the winding of the stator.

[0043] This means that if the rotor is driven by an external force, it will rotate and generate alternating current.

[0044] The generated alternating current is converted into direct current through a rectifier module to charge the lithium battery, allowing the electronic lock to be used normally.

[0045] 2. The right side of the reversing shuttle of the present invention is heavier than the left side, which can ensure that the right side of the reversing shuttle is always tilted, that is, when in the reversing position, it can ensure that the right end of the reversing shuttle is in the inner track.

[0054] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0055] Embodiment 1:

[0056] This embodiment provides an anti-power-off intelligent electronic lock, comprising:

[0057] The lock body 1 comprises a rotating rod 2, and a locking hole 201 is provided on the side wall of the rotating rod 2;

[0058] A locking rod 3, which is slidably disposed in the lock body 1 and cooperates with the locking hole 201;

[0059] The rotating disk 4 is rotatably arranged in the lock body 1 and is provided with a stepping motor drive, and the rotating disk 4 controls the locking rod 3 to slide through the linkage assembly 7. When the rotating disk 4 is reversed, the locking rod 3 is inserted into the locking hole 201, and when it is forwardly rotated, the locking rod 3 is disengaged from the lock hole;

[0060] Hand-cranked mechanism 5 stepper motor; 6, hand-cranked mechanism 5 stepper motor; 6 is used to control the reverse rotation of the rotating disk 4, hand-cranked mechanism 5 stepper motor; 6 includes a unidirectional rotation component;

[0061] A control panel, the control panel is electrically connected to the stepper motor and is used to control the rotation of the stepper motor;

[0062] Lithium battery, lithium battery can power stepper motor, and stepper motor can also charge lithium battery.

[0063] The linkage mechanism such as the lock tongue inside the lock body 1 is the mechanism of the existing smart electronic lock, which is the prior art. The specific structure will not be illustrated or described in detail. The lock body 1 includes a rotating rod 2, which is connected to the handle 8, and the front and rear handles 8 are synchronously rotated and plugged through the square hole and the square rod. A locking hole 201 is provided on the upper side wall of the rotating rod 2, and a locking rod 3 that slides up and down is provided in the lock body 1. When the locking rod 3 slides downward into the locking hole 201, the rotating rod 2 cannot rotate, thereby failing to control the lock tongue and failing to open the door; when the locking rod 3 is disengaged from the locking hole 201, the rotating rod 2 rotates normally to control the extension and retraction of the lock tongue, so that the door can be opened normally; the rotating disk 4 is rotatably arranged in the lock body 1 through the shaft rod provided at the center of the end, and the shaft rod on one side is linked with the main shaft of the stepping motor through a coupling or square rod plugging.

[0064] A stepper motor is a motor that converts electrical pulses into angular displacement. It is widely used in situations where precise control of position and speed is required. Compared with traditional DC motors and AC motors, stepper motors have higher positioning accuracy and good control performance.

[0065] The working principle of stepper motors is based on electromagnetic induction and step control. When the motor receives a control signal, the current flows through the windings inside the motor in a specific order, thereby generating a rotating magnetic field, causing the motor to rotate a fixed angle (called "step"). The angle of each step is determined by the design of the motor, and the common step angle is 1.8° (200 steps / revolution) or 0.9° (400 steps / revolution).

[0066] The stepper motor uses a permanent magnet stepper motor.

[0067] When the stepper motor controls the forward rotation of the rotating disk 4, the locking rod 3 slides upward and the locking rod 3 disengages from the locking hole 201. When the rotating disk 4 reverses, the locking rod 3 is inserted into the locking hole 201, and a hand-cranked mechanism 5 stepper motor is provided; 6 is used to manually control the forward rotation of the rotating disk 4, the hand-cranked mechanism 5 stepper motor; 6 can only control the reverse rotation of the rotating disk 4, not the forward rotation, and the hand-cranked mechanism 5 stepper motor; 6 is provided with a unidirectional rotation component to ensure the hand-cranked mechanism 5 stepper motor; 6 cannot rotate forward, and the forward rotation is the clockwise rotation of the rotating disk 4 in the figure. The control panel is a circuit board that sends forward and reverse rotation signals to the stepper motor and is electrically connected to other components. The lithium battery is used to power the electronic components of the entire electronic lock, and an inverter and a rectifier module are also provided between the lithium battery and the stepper motor. The rectifier module is a power module used to convert AC power into DC power, usually composed of a transformer, a rectifier bridge, a compensation capacitor, etc.; the inverter is a power module that converts DC power into AC power, usually composed of a DC bus, a power switch, a control circuit, etc.

[0068] Working principle:

[0069] When the lithium battery of the electronic lock runs out of power, the hand-cranked mechanism 5 controls the stepper motor; 6 controls the rotating disk 4 to rotate, thereby rotating the rotor of the stepper motor. The permanent magnet stepper motor uses permanent magnets to generate a magnetic field. These permanent magnets are usually fixed on the rotor, and multiple windings are arranged on the stator; when the permanent magnet rotor rotates, the magnetic field around it also changes. According to Faraday's law of electromagnetic induction, the changing magnetic field will induce voltage in the windings of the stator.

[0070] This means that if the rotor is driven by an external force, it will rotate and generate alternating current.

[0071] The generated alternating current is converted into direct current through a rectifier module to charge the lithium battery, allowing the electronic lock to be used normally.

[0072] It should be noted that the unidirectional rotation of the hand-cranked mechanism 5 and the stepping motor 6 is to prevent the hand-cranked mechanism 5 and the stepping motor 6 from being used to control the rotating disk 4 to rotate forward to open the locking rod 3.

[0073] Embodiment 2:

[0074] This embodiment provides an anti-power-off smart electronic lock, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

The track position is rotated by rotating the disk body 401. When the disk body 401 rotates clockwise, the reversing shuttle 702 slides from the outer track 4012 to the inner track 4011, so that the reversing shuttle 702 moves upward, thereby moving the locking rod 3 upward to achieve unlocking, and when reversing counterclockwise, the reversing shuttle 702 returns to the outer track 4012. It should be noted that the shape of the reversing shuttle 702 is preferably a crescent shape. When the reversing shuttle 702 reaches the tangent position of the outer track 4012 and the inner track 4011, the reversing shuttle 702 can move normally through the linkage mode of the crescent shape and the hinge.

[0083] When the disk body 401 is rotating to the connecting position between the outer track 4012 and the inner track 4011 , one end of the reversing shuttle 702 abuts against the side wall of the outer track 4012 , and the other end is in the inner track 4011 .

[0084] When the disk body 401 is rotating to the connecting position of the outer track 4012 and the inner track 4011, one end of the reversing shuttle 702 abuts against the side wall of the outer track 4012 and the other end is in the inner track 4011, which can ensure the completion of the track switching action, and the hinged left side can be longer than the right side, and the right end can always be tilted.

[0088] The right side is heavier than the left side, which can ensure that the right side of the reversing shuttle 702 is always tilted, that is, when in the reversing position, it can ensure that the right end of the reversing shuttle 702 is in the inner track 4011.

[0089] Embodiment 5:
