Description

Technical Field

[0001] This utility model relates to smart locks, and more precisely, to a smart lock system that prevents false locking. Background Technology

[0002] A smart lock includes a lock body, a bolt mounted on the lock body and capable of retracting relative to the lock body, and a bolt drive mechanism for propelling the bolt's retraction. The smart lock is installed on a door panel, and a keyhole is provided on the door frame. When the door is closed, the bolt drive mechanism drives the bolt to extend and insert into the keyhole to lock the door. However, when the door is not fully closed, the bolt and keyhole may misalign. In this case, when the bolt drive mechanism extends the bolt, it is blocked by the door frame after extending to a certain extent, preventing the bolt from inserting into the keyhole. Since the smart lock has already triggered a locking action once, the bolt drive mechanism will not subsequently drive the bolt to extend and lock again, resulting in a false lock. Summary of the Invention

[0003] This invention addresses the technical problem in existing technologies where, when the door is not properly closed, the bolt cannot be inserted into the keyhole, and because the smart lock has already triggered the locking action once, the bolt drive mechanism will not drive the bolt to extend and lock again, resulting in a false lock. This invention provides a smart lock system that prevents false locks.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is to design an anti-false locking smart lock system, including a lock body and a bolt disposed on the lock body and capable of telescopic movement relative to the lock body. The anti-false locking smart lock system further includes:

[0005] The bolt position detection module detects whether the bolt is fully extended when the door is closed, and issues an unlocked signal when the bolt is not fully extended and an locked signal when the bolt is fully extended.

[0006] A bolt drive mechanism is located inside the lock body and drives the lock body to extend and retract.

[0007] A control module is connected to the bolt position detection module and the bolt drive mechanism. The control module receives the unlocked signal and controls the bolt drive mechanism to retract and extend the bolt according to the unlocked signal. The control module controls the bolt drive mechanism to repeatedly retract and extend the bolt until the control module receives the locking signal and then stops controlling the bolt drive mechanism to retract the bolt.

[0008] The smart lock system for preventing false locks also includes:

[0009] The detection tongue is located on the lock body and can extend and retract relative to the lock body. When the door is closed, the detection tongue contacts the door frame and is compressed to send a closing signal. The control module is connected to the detection tongue and controls the bolt drive mechanism to extend the bolt according to the closing signal.

[0010] The bolt drive mechanism includes a motor;

[0011] The bolt position detection module includes:

[0012] The current detection module detects the motor current during the extension of the locking bolt and issues the unlocked signal when a stall current is detected.

[0013] The smart lock system for preventing false locks also includes:

[0014] A voice module is connected to the control module, and when the control module receives the unlocked signal, it outputs a warning signal to the voice module, and the voice module plays a warning sound according to the warning signal.

[0015] The smart lock system for preventing false locks also includes:

[0016] A door frame, wherein a lock hole is provided on the door frame;

[0017] A door panel, which is rotatably connected to one side of the door frame; the lock body is fixed to the door panel;

[0018] The lock body includes:

[0019] The inner lock body is fixed to the inside of the door panel;

[0020] The outer lock body is fixed to the outside of the door panel;

[0021] The smart lock system for preventing false locks also includes:

[0022] A repeat stop button is provided on the inner lock body, and when the repeat stop button is pressed, the control module controls the bolt drive mechanism to stop repeatedly driving the bolt to retract and extend.

[0023] The smart lock system for preventing false locks also includes:

[0024] A communication module is connected to the control module, and the control module controls the communication module to issue a warning message after receiving the unlocked signal;

[0025] A mobile terminal, which is wirelessly connected to the communication module, receives the warning information and issues warnings based on the warning information.

[0026] The smart lock system for preventing false locks also includes:

[0027] A door magnetic detector includes a magnet disposed on the door frame and a door magnetic sensor disposed on the door panel and positioned opposite the magnet when the door is locked; the door magnetic sensor is connected to the control module; when the door magnetic sensor is opposite the magnet, the door magnetic sensor triggers and sends a door closed signal; otherwise, the door magnetic sensor sends a door not closed signal; the control module controls the communication module to send a prompt message to the mobile terminal based on the door not closed signal.

[0028] The door magnetic sensor is wirelessly connected to the communication module.

[0029] This invention utilizes a bolt position detection module, a bolt drive mechanism, and a control module. The bolt position detection module detects whether the bolt is fully extended when the door is closed, issuing an unlocked signal when the bolt is not fully extended and a locked signal when the bolt is fully extended. The control module receives the unlocked signal and controls the bolt drive mechanism to retract and then extend the bolt. The control module controls the bolt drive mechanism to repeatedly retract and extend the bolt until the control module receives the locked signal and then stops controlling the bolt drive mechanism to retract the bolt. Thus, even if the bolt is blocked by the door frame after extending to a certain extent and cannot be inserted into the keyhole when the door is closed, the smart lock's bolt can still repeatedly perform the retraction and extension actions until it is fully extended. This repeated retraction and extension action serves as a reminder to the user that the door is in a loose lock state. Furthermore, by repeatedly performing the retraction and extension actions, the bolt can also be fully inserted into the keyhole and truly locked when the position difference between the bolt and the keyhole is not significant. Attached Figure Description

[0030] The present invention will now be described in detail with reference to the embodiments and accompanying drawings, wherein:

[0031] Figure 1 This is a structural diagram of the intelligent lock system for preventing false locks of this utility model;

[0032] Figure 2 This is a schematic diagram of the intelligent lock system for preventing false locks according to this utility model. Detailed Implementation

[0033] The specific embodiments of this utility model are further described below with reference to the accompanying drawings:

[0034] Please see also Figures 1 to 2 This utility model's anti-false lock intelligent lock system includes a lock body 1, a bolt 2, a bolt position detection module 3, a bolt drive mechanism 4, and a control module 5. Wherein:

[0035] The lock body 1 is mainly used to fix the smart lock to the door panel. In this specific embodiment, the anti-false lock smart lock system also includes a door frame 101 and a door panel 100, wherein: a lock hole 102 is provided on the door frame; the door panel 100 is rotatably connected to one side of the door frame; and the lock body is fixed to the door panel. The lock body 1 includes an inner lock body and an outer lock body, wherein: the inner lock body is fixed to the inner side of the door panel; and the outer lock body is fixed to the outer side of the door panel. The lock hole corresponds to the bolt position; when locking the door, the bolt is inserted into the lock hole to lock the door.

[0036] The bolt 2 is located on the lock body and can extend and retract relative to the lock body.

[0037] The bolt position detection module 3 detects whether the bolt is fully extended when the door is closed, and issues an unlocked signal when the bolt is not fully extended, and an locked signal when the bolt is fully extended. The bolt position detection module can be implemented using a sensor capable of detecting the bolt position, such as a position sensor.

[0038] The bolt drive mechanism 4 is located inside the lock body and drives the lock body to extend and retract. The bolt drive mechanism is implemented using a commonly used motor drive mechanism.

[0039] The control module 5 is connected to the bolt position detection module and the bolt drive mechanism. The control module receives the unlocked signal and controls the bolt drive mechanism to retract and extend the bolt according to the unlocked signal. The control module controls the bolt drive mechanism to repeatedly retract and extend the bolt until the control module receives the locking signal and then stops controlling the bolt drive mechanism to retract the bolt.

[0040] This invention utilizes a bolt position detection module, a bolt drive mechanism, and a control module. The bolt position detection module detects whether the bolt is fully extended when the door is closed, issuing an unlocked signal when the bolt is not fully extended and a locked signal when the bolt is fully extended. The control module receives the unlocked signal and controls the bolt drive mechanism to retract and then extend the bolt. The control module controls the bolt drive mechanism to repeatedly retract and extend the bolt until the control module receives the locked signal and then stops controlling the bolt drive mechanism to retract the bolt. Thus, even if the bolt is blocked by the door frame after extending to a certain extent and cannot be inserted into the keyhole when the door is closed, the smart lock's bolt can still repeatedly perform the retraction and extension actions until it is fully extended. This repeated retraction and extension action serves as a reminder to the user that the door is in a loose lock state. Furthermore, by repeatedly performing the retraction and extension actions, the bolt can also be fully inserted into the keyhole and truly locked when the position difference between the bolt and the keyhole is not significant.

[0041] In this specific embodiment, the anti-false locking smart lock system further includes a detection tongue 6, which is disposed on the lock body and can extend and retract relative to the lock body. When the door is closed, the detection tongue contacts the door frame and is compressed, emitting a closing signal. The control module is connected to the detection tongue and controls the bolt drive mechanism to extend the bolt according to the closing signal. The detection tongue can determine whether the action is opening or closing, thereby triggering the bolt drive mechanism to lock the door when the door is closed.

[0042] In this specific embodiment, the bolt drive mechanism is a motor drive mechanism, which includes a motor. The bolt position detection module includes a current detection module, which detects the motor current during the bolt's extension process and issues the unlocked signal when a stall current is detected. Because the bolt encounters the door frame during extension, it cannot continue to extend. The motor rotation is obstructed, causing a sharp increase in current and generating a stall current. At this point, it can be determined that the bolt is not fully extended, and the current detection module issues the unlocked signal.

[0043] In this specific embodiment, the anti-false locking smart lock system further includes a voice module 7, which is connected to the control module. When the control module receives the unlocked signal, it outputs a warning signal to the voice module, which then plays a warning sound based on the warning signal. Since the bolt may extend completely outside the door frame during repeated retraction and extension, the timely voice reminder from the voice module better alerts the user and prevents the door from being unlocked and in an open state.

[0044] In this specific implementation, the anti-false locking smart lock system also includes a repeat termination button located on the inner lock body. When the repeat termination button is pressed, the control module controls the bolt drive mechanism to stop repeatedly driving the bolt retraction and extension. By using the repeat termination button, the repeated driving of the bolt by the bolt drive mechanism can be manually terminated, thus allowing for manual termination of the repeated driving of the bolt when it is intentionally necessary to leave the door slightly ajar.

[0045] In this specific embodiment, the anti-false lock smart lock system further includes a communication module 8 and a mobile terminal 9, wherein:

[0046] The communication module 8 is connected to the control module, and after receiving the unlocked signal, the control module controls the communication module to issue a warning message.

[0047] The mobile terminal 9 is wirelessly connected to the communication module, receives the warning information, and issues a warning based on the warning information. This allows the user to be promptly informed of any problems with closing the door even when leaving the site, enabling timely remedial measures to be taken.

[0048] In this specific embodiment, the anti-false lock smart lock system further includes a door magnetic detector 91, which can be used to detect whether the door is fully closed. The door magnetic detector 91 includes a magnet 911 disposed on the door frame and a door magnetic sensor 912 disposed on the door panel and positioned opposite the magnet when the door is locked. The door magnetic sensor is connected to the control module. When the door magnetic sensor is facing the magnet, it triggers a door-closed signal; otherwise, it sends a door-not-closed signal. The control module controls the communication module to send a prompt message to the mobile terminal based on the door-not-closed signal. The door magnetic detector further determines whether the door is closed, further improving the security of the smart lock system.

[0049] The door magnetic sensor can be connected to the communication module via wired or wireless means. Since the door magnetic sensor is usually installed at the top of the door panel, which is a distance away from the lock body, it is preferable that the door magnetic sensor is wirelessly connected to the communication module.

[0050] This invention utilizes a bolt position detection module, a bolt drive mechanism, and a control module. The bolt position detection module detects whether the bolt is fully extended when the door is closed, issuing an unlocked signal when the bolt is not fully extended and a locked signal when the bolt is fully extended. The control module receives the unlocked signal and controls the bolt drive mechanism to retract and then extend the bolt. The control module controls the bolt drive mechanism to repeatedly retract and extend the bolt until the control module receives the locked signal and then stops controlling the bolt drive mechanism to retract the bolt. Thus, even if the bolt is blocked by the door frame after extending to a certain extent and cannot be inserted into the keyhole when the door is closed, the smart lock's bolt can still repeatedly perform the retraction and extension actions until it is fully extended. This repeated retraction and extension action serves as a reminder to the user that the door is in a loose lock state. Furthermore, by repeatedly performing the retraction and extension actions, the bolt can also be fully inserted into the keyhole and truly locked when the position difference between the bolt and the keyhole is not significant.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
