First, in the exemplary embodiment, an intelligent lock anti-pry apparatus is provided, which is shown in fig. 1 and 2 and includes a limiting rail 200, an anti-pry plate 300, and a first stepping motor 400. The limiting rails 200 are disposed on the inner wall of the housing 100 of the mechanical lock for the intelligent lock, and one or two limiting rails may be provided, in this embodiment, two limiting rails 200 are taken as an example for description, and the lock housing further includes a key hole (not shown) for unlocking by a mechanical key. The anti-pry plate 300 is disposed on the limiting rail and can move along the length direction of the limiting rail 200, the anti-pry plate 300 includes an anti-pry hole 310 and a limiting groove 320, wherein the anti-pry plate 300 can move on the limiting rail 200 along a first direction a from a first position to a second position, the first position is as shown in fig. 1, the anti-pry hole 310, the lock cylinder 110 and a key hole (not shown) are coaxially arranged, a key can enter the lock cylinder 110 through the key hole (not shown) and the anti-pry hole 310 in sequence, and the second position is as shown in fig. 2, the anti-pry hole 310 is staggered with the lock cylinder 110 and the key hole (not shown), and the lock cannot be unlocked by the key at this time. Specifically, when the anti-prying plate is located at the second position, the intelligent lock is in an anti-prying opening state.

The first stepping motor 400 is also disposed in the housing of the lock, the first stepping motor 400 is connected to a first driving rod 410, and one end of the first driving rod 410, which is far away from the first stepping motor 400, is located in the limiting groove 320, and is used for driving the anti-pry plate 300 to move between the first position and the second position.

Specifically, as shown in fig. 1 and 2, two limiting blocks 321 are respectively disposed on two sides of an opening of the limiting groove 320, and when the first stepping motor 400 drives the anti-pry plate 300 to move, the limiting blocks 321 can prevent the first driving rod 410 from sliding out of the limiting groove 320. Because the anti-prying plate is arranged between the lock cylinder and the key hole in the spare mechanical lock shell, when the first stepping motor 400 drives the anti-prying plate 300 to be positioned at the second position, the anti-prying hole 310, the lock cylinder 110 and the key hole (not shown) are staggered, and a key cannot be inserted into the lock cylinder, so that the anti-prying purpose of the spare mechanical lock of the intelligent lock is realized, and the overall safety performance of the intelligent lock is improved.

As shown in fig. 2 and 4, in one embodiment, the anti-pry plate 300 further includes a locking column 330, and the locking column 330 is protruded from the anti-pry plate 300. The limiting rail 200 is provided with a through hole along a second direction B, wherein the first direction a is perpendicular to the second direction B. When the anti-pry plate 300 moves to the second position, that is, the intelligent lock is in the anti-prying open state, the bolt 600 extends out of the surface of the limiting rail 300 and abuts against the locking column 330 to prevent the anti-pry plate 300 from moving in the direction opposite to the first direction a. Therefore, the key can not be inserted into the lock core, the anti-prying plate 300 is prevented from being violently moved to the first position, and the anti-theft performance of the intelligent lock is enhanced.

With reference to fig. 1 and fig. 2, in an embodiment, a second stepping motor 500 may be further disposed inside a housing of the mechanical lock for a smart lock, and a second driving rod 510 is movably connected to the second stepping motor 500, and is configured to drive the bolt 600 to move telescopically along the second direction B.

As shown in fig. 1 to 4, in one embodiment, a spring 610 is sleeved on the latch 600, one end of the spring 610 is fixed on the limit rail, and the other end is fixed on the latch 600. When the anti-pry plate 300 is at the second position, the second stepping motor 500 drives the bolt to move along the second direction B and abut against the locking column 330, and the spring 610 is changed from the non-telescopic state to the contracted or stretched state; when the anti-pry plate 300 is to move from the second position to the first position, the spring 610 drives the latch 600 to move in the direction opposite to the second direction B under the action of the elastic force and breaks the abutment with the locking post 330, and the spring 610 also changes from the contracted or stretched state to the non-contracted state.

In this embodiment, damping devices (not shown) are disposed at the connection between the first stepping motor 400 and the first driving rod 410 and at the connection between the second stepping motor 500 and the second driving rod 510, so that when the first stepping motor 400 and the second stepping motor 500 are powered off, the first driving rod 410 and the second driving rod 510 can be locked. Therefore, the anti-prying device can also be applied to a low-power-consumption intelligent lock, and in the anti-prying opening state, the first driving rod 410 and the second driving rod 510 are locked to move, and the first stepping motor 400 and the second stepping motor 500 are powered off to save electric power, but the anti-prying state of the anti-prying device is not influenced.

In the embodiment of the present disclosure, as shown in fig. 1 to 5, a metal reed 620 is disposed at one end of the plug 600 close to the locking pin 330, and the plug 600 includes a signal hole running through along the axial direction, a signal line 630 is disposed in the signal hole, one end of the signal line 630 is connected to the control circuit 700 of the smart lock, and the other end is electrically connected to the metal reed 620. The locking post 330 is provided with a grounding reed 331, when the latch abuts against the locking post, the metal reed 620 contacts with the grounding reed 331 to enable the signal line 630 to transmit an electrical signal to the control circuit 700, and the electrical signal is used for representing the anti-prying opening state.

The control circuit 700 is further configured to control the first stepping motor 400 and the second stepping motor 500 to cooperatively drive the anti-pry plate 300 to move from the second position to the first position according to a preset state parameter of the smart lock. The preset state parameter can be an alarm state parameter when the intelligent lock has insufficient power, is halted or has other system faults.

As shown in fig. 5, the control circuit 700 includes a control chip 710, an anti-pry setting module 720, a voltage detection module 730, and an anti-pry control module 740. The anti-pry setting module 720 is used for triggering the system to enable the anti-pry function, and when the system is successfully enabled, that is, the anti-pry plate 300 is at the second position, the signal line 630 outputs an electrical signal, such as a low level signal, to the control chip 710. Then, the battery voltage detection module 730 is configured to detect whether the battery voltage of the smart lock is lower than a threshold, and if so, output a signal to the control chip 710, so that the control chip 710 outputs a tamper-proof failure signal to the tamper-proof control module 740, and the tamper-proof control module 740 is configured to control the first stepping motor 400 and the second stepping motor 500 to cooperatively drive the tamper-proof plate 300 to return to the first position from the second position, where the tamper-proof function is disabled. That is, after the pick-proof function is started, the fault information of the intelligent lock can be detected, and the situation that the pick-proof function cannot be cancelled due to the fault of the intelligent lock is prevented, so that the user cannot unlock the intelligent lock.

In one example, as shown in fig. 6, a specific tamper-proof method may include the following steps:

s101: entering the anti-prying function and setting the anti-prying function. The anti-prying setting is generally used for defaulting anti-prying activation, and if the default is not the activation state, a user is reminded. Specifically, the anti-prying setting module 720 can set to enable anti-prying, the anti-prying setting module 720 can receive an enabling signal, and the enabling signal can be triggered by an external enabling key.

S102: whether to use anti-prying. When the anti-pry setting module 720 receives the enabling signal, it can transmit a command signal to the control chip 710, the control chip 710 sends the enabling command to the anti-pry control module 740, then the anti-pry control module 740 controls the first stepping motor 400 and the second stepping motor 500 to drive the anti-pry plate 300 and the latch 600 to move in a matching manner, when the anti-pry plate 300 moves to the second position, the signal line 630 outputs an electrical signal, such as a low level signal, to the control chip 710, which indicates that the enabling is successful.

S103: and detecting whether a fault occurs. After successful enablement, the fault is checked and can be cleared.

For example, when the smart lock has insufficient power, a crash or other system faults, the control chip 710 may be triggered to output a prying-resistant failure control signal to the prying-resistant control module 740, and the prying-resistant control module controls the second stepping motor 500 to drive the bolt 600, so that the metal reed 620 and the ground reed 331 are disconnected, and then controls the first stepping motor 400 to drive the prying-resistant plate 300 to move to the first position, at this time, the prying resistance is failed, and the user may unlock the smart lock using a spare mechanical key. After the lock is opened, the user can check for the fault and remove the fault.

In one embodiment, the control circuit 700 is further configured to control the first stepping motor 400 and the second stepping motor 500 to cooperatively drive the anti-pry plate 300 to move from the second position to the first position according to different preset state parameters of the smart lock and according to a preset time delay. The preset state parameter can be an alarm state parameter when the intelligent lock has insufficient power, is halted or has other system faults.

In practical application, in order to prevent a lawbreaker from disabling the anti-prying method by means of restarting, powering down, failure and the like of the electronic device, different delay times can be set according to different state parameters to delay the anti-prying setting module 720 to trigger the system to start the anti-prying function, for example, the electric power is insufficient, the preset delay time is 24 hours, and the preset delay time needs to ensure that the electric power is enough to disable the anti-prying function; and restarting the intelligent lock, wherein the preset delay is 5 minutes, the restarting time of the intelligent lock is usually not more than 30 seconds, and the 5 minutes are enough to enable the intelligent lock to be recovered to be normal, so that the situation that the prying prevention is invalid due to the fact that lawless persons restart the intelligent lock by using the electronic equipment is prevented.
