When the electronic lock needs to be unlocked, the electronic lock gives a voltage to the electromagnetic component 70, the electromagnetic component 70 sucks the electromagnetic core 72 back in a power-on state, at the moment, the electromagnetic core 72 loses the limiting contact on the connecting rod 40, and the connecting rod 40 is pushed to the next section of the track under the elastic force action of the elastic sheet 12 to realize unlocking. When the electronic lock is powered off, the electromagnetic iron core is restored to the original position under the action of the return spring 73, but at the moment, the connecting rod 40 is limited by the electromagnetic iron core under the action of the elastic sheet 12, and the unlocking is completed. After unlocking, the latch hook 30 can be separated from the latch bolt 20 at any time, i.e. the purpose of unlocking is achieved. When the user needs to lock again, the box body is directly covered to complete the locking. When the latch hook 30 is pressed into the latch tongue 20 again, the latch tongue 20 drives the link 40 to move along the track, and when the link 40 reaches the position of the electromagnet core 72, the locking is completed. The above process is repeated. The whole process is simple to operate, and good user experience is achieved.

For the electric control part of the electronic lock of the embodiment, the electronic lock in the embodiment further comprises a panel, wherein at least two different position marks are arranged on the panel; the knob is provided with an indicating mark and can rotate around the panel, so that the indicating mark points to any position mark on the panel; the sensor is arranged corresponding to the indicating mark and rotates along with the rotation of the knob, and is used for acquiring the rotation direction of the knob and the position information of the indicating mark; the control device is provided with a switch and used for controlling the locking device based on the rotation direction of the knob, the position of the indication mark and/or the state of the switch under different working modes. Furthermore, in the use process of the electronic lock in the embodiment, the electronic lock can be locked and unlocked only by operating the knob, so that the operation of the user is further simplified. Simultaneously for the form of fingerprint lock, avoided fingerprint lock fingerprint inefficacy or the situation of being difficult to discern, guaranteed the security of electronic lock. The password lock can be unlocked and the password can be set quickly, and the complex operation of the traditional password lock is overcome.

Example 2

As shown in fig. 10 to 15, in the second embodiment of the electronic lock, compared with the first embodiment, the locking device in this embodiment includes a motor 61, a screw 62 in driving engagement with the motor 61, and a threaded sleeve in threaded engagement with the screw 62, the locking element is a movable pin 64 mounted on the threaded sleeve and moving along with the threaded sleeve, the movable pin 64 is driven by the motor 61 to move along with the threaded sleeve, so that the connecting rod 40 is in the unlocked state.

Preferably, the screw sleeve of the present embodiment includes a plurality of clamping arms 63 capable of being opened and closed, and specifically includes two clamping arms 63 divided into two halves, and a thread groove 631 is formed on the clamping arms 63, wherein the thread groove 631 forms a threaded hole matched with the screw 62 when the two clamping arms 63 are closed.

In this embodiment, the lock case 10 is provided with a guide slot, the clamping arm 63 is movably sleeved in the guide slot, and the clamping arm 63 is opened when the clamping arm 63 partially extends out of the guide slot, and the clamping arm 63 is closed to form a threaded hole when the clamping arm is inserted into the guide slot.

By adopting the locking device, the problem that the rotation number of turns of the motor 61 cannot be accurately controlled by the common motor 61, so that the position of the movable pin 64 cannot be accurately controlled is solved, and then the clamping arm 63 can return to the initial position only by giving the motor 61 an operation time, so that the accuracy of each operation is ensured.

The operation of the electronic lock in this example will be described with reference to fig. 10 to 15. The locking device also comprises a locking resetting piece matched with the locking piece, and the locking resetting piece has elastic resetting force enabling the locking piece to move from the second working position to the first working position. The output of the motor 61 is transmitted to the screw 62 via a reduction gear. The screw 62 is engaged with a clamping arm 63 on the screw sleeve, and the clamping arm 63 is provided with a corresponding thread groove 631, wherein the clamping arm 63 is in an initial state of an open state. After the clamping arm 63 enters the guide groove, under the limiting effect of the guide groove, the clamping arm 63 is closed to form a threaded hole to clamp the screw rod 62, when the motor 61 supplies power, the screw rod 62 rotates to drive the clamping arm 63 to move, the clamping arm 63 sequentially drives the movable pin 64 to retract, and the connecting rod 40 can fall back after the movable pin 64 retracts to complete unlocking. After screw 62 rotated a certain position, arm lock 63 walked to the open position of guide slot, and under the elasticity effect of itself, arm lock 63 opened, broke away from screw 62's effect, and the iron core drives arm lock 63 and returns along the guide slot under the effect of elasticity piece that resets, and at this moment, the activity core can be blockked by connecting rod 40, can't restore to initial position. When the user opens the box, the connecting rod 40 is retracted, the movable pin 64 is returned to the initial position, and the clamping arm 63 clamps the screw 62 again.
