The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0057] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0058] Please refer to the following: Figures 1 to 11 The automatic security lock body provided in the embodiments of the present invention will now be described.

[0059] like Figure 1 , Figure 2 As shown, the automatic security lock body of this embodiment of the invention includes: a housing 100, a latch assembly 200, a drive assembly 300, and a control assembly 400;

[0060] Reference Figure 2 The housing 100 has an internal mounting cavity 110 and a first latch hole 120 communicating with the mounting cavity 110 so that the latch assembly 200 extends out from the first latch hole 120; the outer surface of the housing 100 includes a first limiting surface 190.

[0061] Reference Figure 2 , Figure 4 , Figure 5 , Figure 6 The latch assembly 200 is slidably disposed on the housing 100; the latch assembly 200 is located in the mounting cavity 110, and the latch assembly 200 has an extension 210 for extending out of the first latch hole 120; when the extension 210 extends out of the first latch hole 120 to the outside of the mounting cavity 110, the latch assembly 200 is in a locked state; when the extension 210 retracts from the first latch hole 120 to the mounting cavity 110, the latch assembly 200 is in an unlocked state; thus, by controlling the extension or retraction of the extension 210, the lock can be opened or locked.

[0062] Reference Figure 5 and Figure 6 The drive assembly 300 is disposed on the housing 100. The drive assembly 300 is used to drive the extension 210 of the latch assembly 200 to extend and retract. The drive assembly 300 is used to provide power to the latch assembly 200 so as to drive the latch assembly 200 to slide within the housing 100 and control the extension 210 to extend out of the first latch hole 120 or retract from the first latch hole 120 into the mounting cavity 110.

[0063] Reference Figures 1 to 3 The control component 400 is disposed on the housing 100. The control component 400 includes a controller 410, a detection switch 420, and a trigger 430. The trigger 430 can move along a direction perpendicular to the first limiting surface 190 and is used to trigger the detection switch 420. The detection switch 420 and the drive component 300 are both signal connected to the controller 410.

[0064] The mounting cavity 110 can be a closed cavity on the housing 100 or a non-closed cavity; when the mounting cavity 110 is a non-closed cavity, the latch assembly 200, the control assembly 400, and the drive assembly 300 may not be covered by the housing 100.

[0065] The trigger 430 has an initial position and a trigger position located outside the housing 100 on its moving path. The trigger position is located between the initial position and the first limiting surface 190. When the trigger 430 is in the initial position, the detection switch 420 is not triggered. When the trigger 430 is in the trigger position, the trigger 430 triggers the detection switch 420, and the controller 410 controls the drive assembly 300 to drive the extension 210 to extend out of the first locking tongue hole 120.

[0066] The initial and trigger positions of the trigger element 430 are both located outside the housing 100, so that external pressing of the trigger element 430 triggers the detection switch 420. The trigger position corresponds to... Figure 3 X in the initial position corresponds to Figure 3 In the case of Y. When the trigger 430 retracts inward from its initial position, it will move sequentially from the initial position and the trigger position until it is flush with the first limiting surface 190. When the detection switch 420 is triggered, the detection switch 420 will transmit a closing electrical signal to the controller 410. After receiving the closing signal from the detection switch 420, the controller 410 will drive the extension 210 of the latch assembly 200 to extend out of the first latch hole 120 through the control drive assembly 300, so that the latch assembly 200 is in a locked state.

[0067] It is understood that the automatic security lock body of this embodiment is generally installed in a safe or security cabinet with a door. The housing 100 is located on the inside of the door. When the door is closed, it will approach the cabinet. At this time, the trigger 430 on the outside of the housing 100 will also gradually approach the door frame. As the trigger 430 approaches the cabinet, the door frame will press the trigger 430, causing it to move from its initial position to the trigger position, thus triggering the detection switch 420. The controller 410 will then activate the drive assembly 300 to extend the latch assembly 200, so that the extension part 210 extends to the lock hole of the cabinet, achieving the purpose of locking the door. The first limiting surface 190 varies depending on the position of the trigger 430 on the housing 100. Figure 1As shown, the trigger 430 is located on the side of the housing 100 away from the door body, and the first limiting surface 190 is also located on the side of the housing 100 away from the door body. In this case, the first limiting surface 190 abuts against the door frame to limit the swing position of the moving door body and prevent the protruding part 210 of the lock body from deviating excessively from the lock hole of the door frame. This allows for judgment of whether the door body is fully closed when closed, facilitating the protruding part 210 to extend into the lock hole and achieve normal closing. When closing the door, the first limiting surface 190 will gradually approach the door frame of the cabinet; if the first limiting surface 190 abuts against the door frame, the door body has been fully closed, and the protruding part 210 can then extend into the lock hole to lock the door. It should be noted that in actual production, due to manufacturing tolerances, the first limiting surface 190 may not abut against the door frame after closing, and there may be a gap between the first limiting surface 190 and the cabinet body. In addition, in other embodiments, the trigger 430 can also be located on the side of the housing 100 facing the lock hole of the cabinet, such as... Figure 1 If the lock hole surface 191 is positioned as shown, then the first limiting surface is also located on the side of the housing 100 facing the lock hole of the cabinet. The moving direction of the trigger 430 can be parallel to the moving direction of the protrusion 210. At this time, the first limiting surface does not need to abut against the door frame. When the door is closed in place, the protrusion 210 is aligned with the lock hole of the cabinet. The door frame pushes the trigger 430 from the initial position to the trigger position to trigger the detection switch 420, which extends the protrusion 210 into the lock hole, thereby achieving the purpose of locking the door.

[0068] In one embodiment, the automatic security lock body of this embodiment can also be used on a safe with double doors; such as Figures 12 to 14As shown, the safe has a cabinet body 800 and double doors; the double doors have a first door body 910 and a second door body 920 rotatably connected to the cabinet body 800. A housing 100 is disposed inside the first door body 910. The second door body 920 has a latch groove 922 for fitting with the protruding part 210. The second door body 920 has a stop 923 for pressing the trigger 430, which limits the swing position of the first door body 910 and abuts against the first limiting surface 190. When it is necessary to close the safe... When closing the cabinet, first close the second door 920, then close the first door 910. The first door 910 will cause the trigger 430 on the housing 100 to move towards the stop 923, causing the stop 923 to press the trigger 430. This causes the trigger 430 to gradually move from its initial position to the trigger position, triggering the detection switch 420. The controller 410 will then activate the drive assembly 300 to extend the latch assembly 200 so that the extension 210 extends into the latch groove 922 of the cabinet 800, thus locking the door. When the first limiting surface 190 abuts against the stop 923, it indicates that the first door 910 has been closed and the extension 210 is aligned with the latch groove 922. It should be noted that in actual production, due to manufacturing tolerances, the first limiting surface 190 may not abut against the stop 923 after the door is closed, and there may be a gap between the first limiting surface 190 and the stop 923. In addition, in other embodiments, the trigger 430 may also be disposed on the side of the housing 100 facing the latch groove 922 of the second door body 920, such as... Figure 1 If the lock hole surface 191 is positioned as shown, then the first limiting surface is also located on the side of the housing 100 facing the latch groove 922 of the second door 920, and the moving direction of the trigger 430 can be parallel to the moving direction of the protrusion 210. At this time, the first limiting surface does not need to abut against the stop edge 923; when the first door 910 is closed in place, the protrusion 210 is aligned with the latch groove 922 of the second door 920, and the second door 920 pushes the trigger 430 from the initial position to the trigger position to trigger the detection switch 420, extending the protrusion 210 into the lock hole to achieve the purpose of locking the door.

[0069] Therefore, when the user closes the safe door, the trigger 430 will be pressed, causing it to gradually move from its initial position to the trigger position, thereby triggering the detection switch 420. This causes the controller 410 to control the drive assembly 300 to extend the latch assembly 200, achieving the purpose of locking the door. In this way, the user can lock the door without manually turning the knob or handle, avoiding situations where the safe or security cabinet is left unlocked due to forgetting to turn the knob or handle, thus reducing unnecessary property losses.

[0070] It should be noted that the controller 410 can be made using a PLC (Programmable Logic Controller) or an MCU (Microcontroller Unit) chip. The controller 410 has functions such as logic operation, data processing, and circuit control to receive the closing signal from the detection switch 420 and control the start-up of the drive assembly 300. The controller 410 can be installed in the mounting cavity 110 within the housing 100. Alternatively, the controller 410 can be installed in other locations within the housing 100.

[0071] To ensure that trigger 430 can be used multiple times, refer to... Figure 2 and Figure 3 The outer side of the housing 100 is provided with a button hole 130 communicating with the mounting cavity 110. The trigger 430 has a pressing post 431 and a limiting section 432. The control assembly 400 includes a reset device 433. The pressing post 431 is provided with a pressing end 434 extending from the button hole 130 to the outside of the housing 100. The limiting section 432 is located inside the mounting cavity 110 and is connected to the pressing post 431. The reset device 433 is provided on the housing 100 and is used to drive the pressing post 431 to extend outward from the housing 100. External force can be applied by pressing or pushing the pressing end 434 to move the pressing post 431 in a direction perpendicular to the first limiting surface 190, so that the trigger 430 moves from the initial position to the trigger position, or can move to a position flush with the first limiting surface 190. The pressing end 434 is the contact position between the trigger 430 and the aforementioned stop 923 or door frame. The door frame or stop 923 can move the pressing end 434 towards the first limiting surface 190 to move the pressing end 434 to the trigger position to trigger the detection switch. That is, when the pressing end 434 is in the initial position, the detection switch 420 is not triggered; when the pressing end 434 is in the trigger position, the pressing column 431 triggers the detection switch 420. When the pressing end 434 is not pressed by external force, the reset device 433 is used to push the pressing column 431 outward to the initial position to place the pressing end 434 outside the housing 100 so that it can be pressed by external force, facilitating the feedback of the door closing signal to the controller 410, so that the controller 410 can control the drive assembly 300 to drive the extension 210 of the latch assembly 200 to extend to the locked state. The pressing end 434 and the limiting section 432 are located at the two ends of the pressing column 431, respectively. When the reset device 433 pushes the pressing column 431 outward, the limiting section 432 is located inside the housing 100 and abuts against the housing 100, preventing the pressing column 431 from coming out of the button hole 130.

[0072] It should be noted that the pressing post 431 can extend and retract at the button hole 130 to facilitate external pressing of the trigger element 430 and its reset. The extension direction of the pressing post 431 is parallel to the movement direction of the trigger element 430, allowing the pressing post 431 to extend or retract from the button hole 130. The reset device 433 is a compression spring, with one end abutting against the housing 100 and the other end abutting against the pressing post 431, providing an outward pushing force to ensure the pressing post 431 resets promptly after being pressed.

[0073] In one embodiment, reference is made to Figure 2 and Figure 3 The controller 410 and the detection switch 420 are both located inside the mounting cavity 110. The limit section 432 is provided with a trigger part 435 for triggering the detection switch 420. The detection switch 420 and the trigger part 435 are both located inside the housing 100 to protect the detection switch 420 and the trigger part 435. This ensures that during multiple presses of the trigger 430, the trigger part 435 triggers the detection switch 420 through position changes, so that the detection switch 420 sends a door closing signal back to the controller 410.

[0074] Specifically, in this embodiment, the detection switch 420 is a Hall switch, and the trigger part 435 is provided with a magnetic element 436 for triggering the Hall switch. The magnetic element 436 can be a permanent magnet with magnetism; since the magnetic element 436 is provided on the trigger part 435, when the pressing column 431 is pressed, it will retract inward, and the distance between the detection switch 420 and the magnetic element 436 will change, thus changing the magnetic field around the Hall switch to feed back an electrical signal to the controller 410. Among them, when the reset device 433 pushes the pressing column 431 outward and the limiting section 432 abuts against the housing 100, the distance between the Hall switch and the magnetic element 436 is the shortest. In addition, the detection switch 420 can also be replaced by commonly used limit switches, photoelectric sensors, and other detection elements.

[0075] In one embodiment, reference is made to Figure 3When the first limiting surface 190 abuts against the stop 923 or the door frame, restricting the position of the door, the pressing end 434 of the trigger 430 is flush with the first limiting surface 190, and cannot be pressed further inward by the safe. Due to manufacturing tolerances during mass production, the door of the safe cannot fit against the door frame or stop 923 when closed during actual installation. Therefore, in order to ensure that the extension part 210 of the lock body extends when the safe is closed, the detection switch 420 should be triggered before the trigger 430 retracts to be flush with the first limiting surface 190. In order to ensure that the door frame or stop 923 can push the trigger 430 to the trigger position, the travel distance d1 between the trigger position and the first limiting surface 190 is ≥1mm. When the travel distance between the trigger position and the first limiting surface 190 is less than 1 mm, if the user closes the door and the gap between the door frame or edge 923 and the first limiting surface 190 is greater than or equal to 1 mm, the detection switch 420 cannot be triggered, resulting in the safe failing to lock and potentially causing unnecessary property loss. In actual production, the manufacturing tolerance of the door frame or edge 923 of the safe is 0 to 1 mm, so the travel distance between the trigger position and the first limiting surface 190 is greater than 1 mm, ensuring that the detection switch 420 can be triggered when the safe is closed, thus achieving automatic locking. In this embodiment, the travel distance between the trigger position and the first limiting surface 190 is 2 mm.

[0076] Based on the above, when the pressing end 434 is in the initial position, the travel distance between the initial position and the trigger position is the effective travel distance d2 of the trigger 430 (refer to...). Figure 3 In the case of the safe closing process, the trigger element 430 must move the effective travel distance before the detection switch 420 can be triggered. When a Hall switch is selected as the detection switch 420, the travel distance of the magnetic element 436 will cause a change in the potential of the Hall switch. That is, when the effective travel distance of the magnetic element 436 is too small, it is difficult to cause a change in the potential of the Hall switch. The magnetic induction intensity of the magnetic element 436 is proportional to the Hall potential U of the Hall switch. After a lot of trials, the effective travel distance of the magnetic element 436 in this embodiment needs to be greater than or equal to 2 mm to cause a change in the Hall potential U of the Hall switch, so that the Hall switch sends the information that the trigger element 430 has moved from the initial position to the trigger position to the controller 410, so as to provide a closing signal, so that the controller 410 controls the drive assembly 300 to drive the extension 210 of the latch assembly 200 to extend to the locked state. Secondly, since the thickness of the housing 100 needs to be less than the thickness of the first door 910, and the thickness of a typical safe is 25 mm, the travel distance between the pressing end 434 and the trigger position is 2 mm to 24 mm, ensuring that the limiting section 432 of the pressing column 431 can move within the mounting cavity 110.

[0077] In one embodiment, reference is made to Figure 14 and Figure 15 The housing 100 of the automatic security lock is mounted on the door. The door has an edging 912 to surround the housing 100, which allows the housing to be mounted on the door and also protects the housing 100. The edging 912 is located on the edge of the door and covers the first limiting surface 190 on the housing 100, so the first limiting surface 190 cannot function as a limiting surface. The edging 912 is then provided with a second limiting surface 913, which is located between the trigger position and the first limiting surface 190. This is so that the trigger position is located on the side of the second limiting surface 913 away from the first limiting surface 190, allowing the pressing end 434 of the trigger 430 to trigger the detection switch 420 before it retracts to be flush with the second limiting surface 913. When the door is closed, the second limiting surface 913 gradually approaches the door frame or edge 923. The door frame or edge 923 then pushes the trigger 430, moving it from its initial position to the trigger position to trigger the detection switch 420. The second limiting surface 913 restricts the swing position of the movable door and can abut against the door frame or edge 923. When the second limiting surface 913 abuts against the edge 923, it indicates that the first door 910 has closed completely and the protrusion 210 is aligned with the latch groove 922. It should be noted that in actual production, due to manufacturing tolerances, the second limiting surface 913 may not abut against the edge 923 after the door is closed, and there may be a gap between the second limiting surface 913 and the edge 923.

[0078] Based on the above, and referring to Figure 15When the second limiting surface 913 abuts against the stop 923 or the door frame, restricting the position of the door, the pressing end 434 of the trigger 430 is flush with the second limiting surface 913, and cannot be pressed further inward by the safe. Due to manufacturing tolerances during mass production, the door of the safe cannot fit against the door frame or stop 923 when closed. Therefore, in order to ensure that the extension part 210 of the lock body extends when the safe is closed, the detection switch 420 should be triggered before the trigger 430 retracts to be flush with the second limiting surface 913. In order to ensure that the door frame or stop 923 can push the trigger 430 to the trigger position, the travel distance d3 between the trigger position and the second limiting surface 913 is ≥1mm. When the travel distance between the trigger position and the second limiting surface 913 is less than 1 mm, if the user closes the door and the gap between the door frame or edge 923 and the first limiting surface 190 is greater than or equal to 1 mm, the detection switch 420 cannot be triggered, resulting in the safe failing to lock and potentially causing unnecessary property loss. In actual production, the manufacturing tolerance of the door frame or edge 923 of the safe is 0 to 1 mm. Therefore, the travel distance between the trigger position and the second limiting surface 913 is greater than 1 mm, ensuring that the detection switch 420 can be triggered when the safe is closed, thus achieving automatic locking. In this embodiment, the travel distance between the trigger position and the second limiting surface 913 is 2 mm.

[0079] To remind users to close the door in time, refer to Figure 1 and Figure 2 The automatic security lock also includes an alarm device 500, which is signal-connected to the controller 410. The controller 410 has a timing module. When the controller 410 does not receive information from the trigger 430 triggering the detection switch 420 within a preset time, the controller 410 activates the alarm device 500. When the user closes the door, the door frame of the safe or security cabinet will continuously press the trigger 430; when the user opens the door, the trigger 430 will no longer be pressed by the door frame and will reset. At this time, the detection switch 420 will not be triggered by the trigger 430. The controller 410 has a timing module. When the controller 410 does not receive information from the detection switch 420 being triggered by the trigger 430 within a preset time, the controller 410 will control the alarm device 500 to issue an audible and visual alarm to remind the user that the door 900 is not closed and needs to be closed to reduce unnecessary property loss. It should be noted that the alarm device 500 can be a commonly used alarm device such as a buzzer or audible and visual alarm to provide audible and visual alarm information to remind users. The preset time can be set to 3 minutes, 4 minutes, etc. It should also be noted that the timing module can be a timer made from a commonly available crystal oscillator.

[0080] To better allow the latch assembly 200 to extend outside the housing 100, refer to... Figures 4 to 7 The latch assembly 200 has a first transmission member 220; the first transmission member 220 is slidably connected to the housing 100, and the sliding direction of the first transmission member 220 is a first linear direction, which is parallel to the extension and retraction direction of the protrusion 210; the protrusion 210 is disposed on the first transmission member 220; the drive assembly 300 is used to drive the first transmission member 220 to slide along the first linear direction, so that the protrusion 210 retracts from or extends from the first latch hole 120. When the protrusion 210 is outside the mounting cavity 110, both the first transmission member 220 and the protrusion 210 are in a locked state; when the protrusion 210 is inside the mounting cavity 110, both the first transmission member 220 and the protrusion 210 are in an unlocked state. By providing the first transmission member 220, the drive assembly 300 can drive the protrusion 210 to extend and retract via the first transmission member 220, thereby improving unlocking and locking.

[0081] Among them, reference Figures 4 to 7 The drive assembly 300 includes a drive device 310 and a rotating lever 320. The drive device 310 drives the rotating lever 320 to rotate. The first transmission member 220 is provided with a moving groove 221, and one end of the rotating lever 320 is located in the moving groove 221. When the rotating lever 320 rotates, it drives the first transmission member 220 to slide along a first linear direction through the moving groove 221. The drive device 310 is a drive motor, and the rotating lever 320 is mounted on the rotating rod of the drive motor so that the drive motor drives the rotating lever 320 to rotate. When the rotating lever 320 rotates, it can drive the first transmission member 220 to slide along the first linear direction through the moving groove 221, thereby driving the extension portion 210 to extend and retract in the first linear direction.

[0082] Specifically, refer to Figures 4 to 7To better connect the drive device 310 and the rotating lever 320, the rotating lever 320 has a rotating seat 321 and a toggle block 322. The toggle block 322 is disposed at one end of the rotating lever 320 and is located within the toggle groove 221. The rotating seat 321 is connected to the drive device 310. The rotating seat 321 and the toggle block 322 are located at opposite ends of the rotating lever 320 to increase the driving arm of the rotating lever 320, thereby increasing the power transmitted from the rotating lever 320 to the first transmission member 220, so as to drive the first transmission member 220 to slide. The rotating seat 321 is provided with a mounting flat position, which cooperates with the flat position of the rotating rod of the drive device 310, so that the rotating rod of the drive device 310 can transmit power to the rotating lever 320. The toggle block 322 is used to abut against the toggle groove 221 to drive the first transmission member 220 to slide through the toggle groove 221. The actuating block 322 can be an actuating wheel. The actuating wheel is rotatably connected to the rotating lever 320. The actuating block 322 can rotate on the rotating lever 320 to reduce the friction between the actuating block 322 and the actuating groove 221, so that the rotating lever 320 can better drive the first transmission member 220 to slide in the first linear direction when rotating.

[0083] To better transmit power, refer to Figures 4 to 7 The length direction of the actuating groove 221 is the second straight line direction, and the actuating groove 221 is provided with two abutting surfaces 222 parallel to the second straight line direction; the actuating block 322 is located between the two abutting surfaces 222, and the two abutting surfaces 222 are used to abut against the actuating block 322; the actuating groove 221 is a straight groove, so when the rotating lever 320 rotates, it will move between the two abutting surfaces 222, and drive the first transmission member 220 to move in different directions by abutting the actuating block 322 against different abutting surfaces 222; when the actuating block 322 abuts against one of the abutting surfaces 222, the rotating lever 320, the actuating block 322, the actuating groove 221, and the first transmission member 220 form an eccentric wheel mechanism, and the rotating lever 320 can drive the first transmission member 220 to move through the eccentric wheel mechanism. In one embodiment, the second linear direction is perpendicular to the first linear direction. When the actuating block 322 of the rotating lever 320 abuts against the contact surface 222, it will transmit a thrust parallel to the first linear direction to the first transmission member 220 so as to drive the first transmission member 220 to move in the first linear direction.

[0084] For ease of explanation, refer to Figures 4 to 7 In this embodiment, when the drive device 310 rotates forward, the lever 320 rotates forward to drive the extension 210 of the first transmission member 220 to extend outward; when the drive device 310 rotates in reverse, the lever 320 rotates in reverse to drive the extension 210 of the first transmission member 220 to retract inward.

[0085] To prevent external prying of the lock via the protrusion 210, refer to... Figures 4 to 7 The housing 100 is provided with a self-locking limiting part 140 for abutting against the rotating lever 320. When an external force drives the extended part 210, which is in a locked state, to retract into the first locking tongue hole 120, the abutting surface 222 drives the rotating lever 320 to abut against the self-locking limiting part 140 through the actuating block 322, so that the extended part 210 remains in a locked state. The self-locking limiting part 140 is used to limit the forward rotation range of the rotating lever 320. When an external force pushes the extended part 210 to retract inward, the first transmission member 220 will drive the rotating lever 320 through the abutting surface 222 and the actuating block 322, so that the rotating lever 320 continues to rotate forward to abut against the self-locking limiting part 140. At this time, the rotating lever 320 will not be pushed to reverse by the external force, thus ensuring that the extended part 210 remains in a locked state and preventing the external force from pushing the extended part 210 back into the mounting cavity 110, thereby achieving the purpose of self-locking and anti-pry.

[0086] It should be noted that in this embodiment, the direction between the rotation center of the driving device 310 and the rotation center of the actuating block 322 is defined as the lever direction. When the lever direction is the same as the retraction direction of the protruding part 210, the actuation angle of the rotating lever 320 is defined as 0 degrees. When the rotating lever 320 reverses from a 0-degree angle, the actuation angle is negative; when the rotating lever 320 rotates forward from a 0-degree angle, the actuation angle is positive. The actuation angle range of the rotating lever 320 is -30 degrees to Z degrees, where 185 ≤ Z ≤ 210 (refer to...). Figure 6 In embodiment B), the rotation angle of the lever 320 under the drive of the drive device 310 ranges from -30 degrees to Z degrees. In this embodiment, when the rotation angle of the lever 320 is between -30 degrees and 0 degrees, both the protrusion 210 of the latch assembly 200 and the lever 320 are in an unlocked state; when the rotation angle of the lever 320 is between 180 degrees and Z degrees, both the protrusion 210 of the latch assembly 200 and the lever 320 are in a locked state. When the lever 320 abuts against the self-locking limiting part 140, the rotation angle of the lever 320 is Z degrees.

[0087] In other embodiments, the position of the self-locking limiting part 140 can be adjusted according to the actual situation to adjust the angle range of the rotating lever 320, so that when the rotating lever 320 abuts against the self-locking limiting part 140, the angle of the rotating lever 320 is 185 degrees to 210 degrees.

[0088] In order to provide feedback on the position information of the first transmission member 220 and the protrusion 210, refer to Figure 4 , Figure 8The first transmission component 220 is provided with a limit stop 223; the housing 100 is provided with a first position switch 150 for detecting the limit stop 223; the first position switch 150 is signal-connected to the controller 410; when the first transmission component 220 is in the locked state, the limit stop 223 triggers the first position switch 150. The limit stop 223 is provided on the first transmission component 220. When the first transmission component 220 slides under the drive of the drive device 310, it will trigger the first position switch 150 or disengage from the first position switch 150; when the first transmission component 220 is driven to the locked state position by the drive device 310, the protrusion 210 is also in the locked state position. The limit stop 223 triggers the first position switch 150 to provide feedback to the controller 410 that the protrusion 210 is in the locked state, so that the controller 410 can perform corresponding operations based on the position information of the protrusion 210. For example, when the controller 410 controls the drive device 310 to rotate forward, the extension part 210 will extend outward to the locked position. When the extension part 210 reaches the locked position, the limit block 223 triggers the first position switch 150 to provide feedback to the controller 410 that the extension part 210 has reached the locked position. The controller 410 then controls the drive device 310 to stop rotating forward in time to avoid damage to the drive device 310 and to save energy.

[0089] In addition, since the lock body of the safe or security cabinet is generally in a locked state, if the controller 410 does not receive feedback information from the first position switch 150 (the extension 210 is in a locked state) within a preset time, the controller 410 will sound an alarm through the alarm device 500, so that the user can check the current usage status of the safe or security cabinet in a timely manner and avoid unnecessary property loss.

[0090] To better detect the position information of the protrusion 210, refer to Figure 4 , Figure 8The housing 100 is provided with a second position switch 160 for detecting the limit stop 223. The second position switch 160 is signal-connected to the controller 410. When the first transmission member 220 is in the unlocked state, the limit stop 223 triggers the second position switch 160. The limit stop 223 is located between the first position switch 150 and the second position switch 160. When the drive device 310 drives the first transmission member 220 to move, it can move the limit stop 223 from the position corresponding to triggering the first position switch 150 to the position corresponding to triggering the second position switch 160, so as to trigger both the first position switch 150 and the second position switch 160. When the first transmission component 220 moves to the unlocked position under the drive of the drive device 310, the protrusion 210 is in the unlocked position. The limit stop 223 moves to the position corresponding to trigger the second position switch 160, so as to trigger the second position switch 160. The second position switch 160 feeds back the current position information of the protrusion 210 in the unlocked state to the controller 410, so that the controller 410 can perform corresponding operations based on the position information of the protrusion 210. For example, when the controller 410 controls the drive device 310 to reverse, the protrusion 210 will retract inward to the unlocked position. When the protrusion 210 reaches the unlocked position, the limit stop 223 triggers the second position switch 160, feeding back the current position information of the protrusion 210 reaching the unlocked position to the controller 410. The controller 410 then controls the drive device 310 to stop reversing in time, avoiding damage to the drive device 310 and saving energy.

[0091] In addition, since the lock body of the safe or security cabinet is generally in the locked state, if the controller 410 continuously receives feedback information from the second position switch 160 (the extension 210 is in the unlocked state) within a preset time, the controller 410 will sound an alarm through the alarm device 500, so that the user can check the current usage status of the safe or security cabinet in a timely manner and avoid unnecessary property loss.

[0092] It should be noted that the first position switch 150 and the second position switch 160 can be made using photoelectric sensors, limit switches, or other detection switches.

[0093] To facilitate the supply of power to the controller 410 and the drive assembly 300, refer to Figure 1 , Figure 2 , Figure 9 The automatic security lock body also includes a battery compartment 600; the battery compartment 600 is electrically connected to the controller 410 and the drive assembly 300. The battery compartment 600 can be installed on the housing 100 or outside the housing 100.

[0094] Specifically, refer to Figure 1 , Figure 2 , Figure 9To facilitate battery compartment 600 replacement, the battery compartment 600 is detachably mounted on the housing 100. The battery compartment 600 is provided with a first output interface 610; the housing 100 is provided with a first input interface 170 electrically connected to the controller 410 and the drive assembly 300. When the battery compartment 600 is fixed to the housing 100, the first output interface 610 is electrically connected to the first input interface 170. The battery compartment 600 can be detached from the housing 100, allowing for direct replacement of the lock body with a new battery compartment 600. When the battery compartment 600 is installed on the housing 100, its first output interface 610 is electrically connected to the first input interface 170 on the housing 100, enabling power transmission from the battery compartment 600 to the controller 410 and the drive assembly 300 for their normal operation.

[0095] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 9 The housing 100 is provided with a mounting slot 180, and the battery compartment 600 is provided with a mounting buckle 620 for engaging with the mounting slot 180. When the mounting buckle 620 of the battery compartment 600 engages with the mounting slot 180, the first output interface 610 is electrically connected to the first input interface 170. The mounting buckle 620 can extend into the mounting slot 180 and then engage with the locking interface of the mounting slot 180 to achieve the purpose of installation and fixation. In addition, the battery compartment 600 can also be fixed to the housing 100 by a buckle or slot engagement, or by a detachable connection such as screws or bolts.

[0096] To facilitate transportation and save energy, refer to Figure 1 , Figure 2 , Figure 9 , Figure 10The automatic security lock also includes: an operation panel 700; the operation panel 700 is provided with a second input interface 710; the second input interface 710 is electrically connected to the controller 410 and the drive assembly 300; the battery compartment 600 is provided with a second output interface 630, which is used to connect to the second input interface 710. The operation panel 700 is provided with a touch panel, a base, a display screen, a main control board, and a fingerprint unlocker; the controller 410 is signal-connected to the touch panel, the display screen, the main control board, and the fingerprint unlocker, so that the user can unlock the lock by operating the touch panel and the fingerprint unlocker. The touch panel can input a numeric password, and the fingerprint unlocker can unlock the electronic lock by detecting the fingerprint of the person unlocking it. The base is installed on the door 900 of the safe or security cabinet. When transporting the safe or security cabinet, the battery compartment 600 can be removed, and its second output interface 630 can be connected to the second input interface 710 to power the drive assembly 300, controller 410, touch panel, display screen, main control board, and fingerprint unlocker. This allows the automatic security lock of the safe or security cabinet to lock the door 900, saving space and preventing the door 900 from shaking during transport. After the door 900 is closed and locked, the second output interface 630 can be removed to de-energize the lock, keeping the door 900 locked. During transport, the lock is not powered, and the battery compartment 600 will not provide power to the lock, saving power and preventing energy loss during transport. This ensures that the battery compartment 600 has sufficient power to open the safe or security cabinet upon delivery. In addition, when the safe or vault is delivered to the user, the user does not need to find or carry a power bank. The battery compartment 600 can be used as a power bank, and the second output interface 630 and the second input interface 710 can provide power to the lock body inside the door from outside, making it convenient to open the safe or vault for the first time at the user's location and improving the user experience. In this embodiment, the second output interface 630 is an output plug.

[0097] In addition, in some embodiments, the battery compartment 600 does not need to have a second output interface. That is, the battery compartment 600 uses a first output interface to connect to the second input interface, so that the battery compartment 600 can be connected to the second input interface or the first input interface with a single interface, reducing the number of output interfaces of the battery compartment 600 and saving costs. It should be noted that when the battery compartment 600 uses a single interface to connect to the second input interface or the first input interface, the form of the first output interface of the battery compartment must correspond to the form of the second input interface and the first input interface. That is, the first output interface is a plug, and the second input interface and the first input interface are both of the same type of socket or outlet, which facilitates connection with the plug of the first output interface.

[0098] To transmit power to the top and bottom locks of a safe or vault, refer to... Figures 4 to 7 The latch assembly 200 also includes a second transmission member 230 and a third transmission member 240; both the second transmission member 230 and the third transmission member 240 are slidably connected to the housing 100, and the sliding direction of the second transmission member 230 and the third transmission member 240 is perpendicular to the first linear direction; the first transmission member 220 connects the second transmission member 230 and the third transmission member 240 through a transmission mechanism; the drive assembly 300 drives the second transmission member 230 and the third transmission member 240 to move towards each other or away from each other through the first transmission member 220. The housing 100 is provided with a slide groove for slidably connecting with the second transmission member 230 and the third transmission member 240, and both the second transmission member 230 and the third transmission member 240 are provided with slide rails extending into the slide grooves so that the second transmission member 230 and the third transmission member 240 can slide along the slide grooves. The second transmission member 230 is disposed on the upper side of the first transmission member 220, and the third transmission member 240 is disposed on the lower side of the first transmission member 220; the housing 100 is provided with a first transmission hole for the second transmission member 230 to extend out and a second transmission hole for the third transmission member 240 to extend out, so that the second transmission member 230 and the third transmission member 240 transmit power to the lock of the safe or security cabinet.

[0099] During the sliding process, the first transmission member 220 transmits power to the second transmission member 230 and the third transmission member 240 through the transmission mechanism, causing the second transmission member 230 and the third transmission member 240 to move in opposite directions or towards each other, so as to achieve the purpose of locking and unlocking.

[0100] To simplify the transmission mechanism, refer to Figures 4 to 7 The second transmission member 230 is provided with a first transmission groove 231, and the third transmission member 240 is provided with a second transmission groove 241. The transmission mechanism includes a first transmission column 224 and a second transmission column 225. Both the first transmission column 224 and the second transmission column 225 are disposed on the first transmission member 220, with the first transmission column 224 located within the first transmission groove 231 and the second transmission column 225 located within the second transmission groove 241. The first transmission member 220 drives the second transmission member 230 and the third transmission member 240 to move towards or away from each other via the first transmission column 224 and the second transmission column 225. When the first transmission member 220 slides, the first transmission column 224 moves in the first transmission groove 231 to push the second transmission member 230 to slide through the first transmission groove 231. Similarly, when the first transmission member 220 slides, the second transmission column 225 moves in the second transmission groove 241 to push the third transmission member 240 to slide through the second transmission groove 241.

[0101] It should be noted that both the first transmission groove 231 and the second transmission groove 241 are straight grooves, and the straight directions of both the first transmission groove 231 and the second transmission groove 241 form an angle with the first straight direction, so that the first transmission member 220 transmits power to the second transmission member 230 and the third transmission member 240 through the first transmission post 224 and the second transmission post 225. In one embodiment, the first transmission groove 231 and the second transmission groove 241 can be machined into an oblong shape so that the first transmission post and the second transmission post 225 can extend into the oblong shape to complete the assembly.

[0102] Reference Figures 12 to 14 The present invention also provides a safe, which includes the above-mentioned automatic safe lock body, cabinet body 800, and double doors;

[0103] The cabinet 800 has a receiving cavity 820 with an opening (not shown in the figure). The double doors are used to close the opening. The double doors include a first door 910 and a second door 920 that are rotatably connected to the cabinet 800. The housing 100 is located inside the first door 910, and the first door 910 may be provided with a edging 912 to surround the housing 100. The second door 920 is provided with a latching groove 922 for fitting with the protrusion 210. The second door 920 is provided with a pressing block 921. The first door 910 and the second door 920 are rotatably connected to the cabinet 800 through a hinge assembly. When the second door 920 flips to close part of the opening, the first door 910 will flip to close the remaining part of the opening. After the first door 910 and the second door 920 cooperate to close the opening, an automatic security lock is used to lock the first door 910 and the second door 920 to lock the security cabinet. The size of the protrusion 210 is adapted to the size of the latch groove 922 so that after the protrusion 210 extends into the latch groove 922, the automatic security lock body locks the first door 910 and the second door 920.

[0104] Pressing block 921 is set on the second door 920 and is used to press trigger 430. When the safe needs to be closed, the second door 920 is closed first, and then the first door 910 is closed. The first door 910 drives the trigger 430 on the housing 100 to move toward pressing block 921, so that pressing block 921 presses trigger 430, so that trigger 430 moves from the initial position to the trigger position, thereby triggering detection switch 420. This causes controller 410 to receive the door closing signal and start drive assembly 300 to drive lock tongue assembly 200 to extend outward to the locked state and into the lock slot 922, so as to achieve the purpose of automatically locking the door using the automatic safe lock body.

[0105] Specifically, in this embodiment, a stop 923 is provided on the side of the second door 920 facing the first door 910, and a pressing block 921 is disposed on the stop 923. The stop 923 is used to limit the swing amplitude of the first door 910. When the first limiting surface 190 abuts against the stop 923, it can be determined that the first door 910 has been closed. Moreover, the stop 923 facilitates the first door 910 to cooperate with the second door 920 to close the opening, reducing the gap between the first door 910 and the second door 920, and playing a role in preventing prying. The trigger 430 is disposed on the housing 100 facing the stop 923, so that when the first door 910 closes, it drives the trigger 430 to approach the stop 923, making it convenient for the stop 923 to press the trigger 430 to trigger the detection switch 420. It should be noted that the pressing block 921 can be part of the stop 923 or can be set as a protrusion on the stop 923. It should be noted that when the first door body 910 is equipped with a edging 912 surrounding the housing 100, the second limiting surface 913 on the edging 912 is used to cooperate with the stop 923 to limit the swing amplitude of the first door body 910, so as to determine that the first door body 910 is closed, and to facilitate the alignment of the protruding part 210 with the latch groove 922. Specifically, to ensure that the stop 923 can push the trigger 430 to the trigger position, the travel distance d3 between the trigger position and the second limiting surface 913 is ≥ 1 mm. When the travel distance between the trigger position and the second limiting surface 913 is less than 1 mm, if the user closes the door and the gap between the stop 923 and the first limiting surface 190 is greater than or equal to 1 mm, the detection switch 420 cannot be triggered, resulting in the failure to lock the safe, which could easily lead to unnecessary property loss. In actual production, the manufacturing tolerance of the guard edge 923 of the safe is 0 to 1 mm. Therefore, the travel distance between the trigger position and the second limiting surface 913 is greater than 1 mm, which ensures that the detection switch 420 can be triggered when the safe is closed, so as to achieve the purpose of automatic locking. In this embodiment, the travel distance between the trigger position and the second limiting surface 913 is 2 mm.

[0106] Reference Figures 11 to 14 The safe also includes: an operation panel 700;

[0107] The operation panel 700 is signal-connected to the controller 410. The operation panel 700 is located on the outside of the first door 910. An anti-tamper alarm switch 720 is located on the side of the operation panel 700 facing the first door 910, and the anti-tamper alarm switch 720 is signal-connected to the controller 410. The anti-tamper alarm switch 720 is a limit switch. When the operation panel 700 is pried up, the anti-tamper alarm switch 720 will detect the distance between the operation panel 700 and the outside of the first door 910, and will then send feedback information to the controller 410. The alarm device 500 will then issue an audible and visual alarm to the user.

[0108] Reference Figures 11 to 14To facilitate better door closing, magnets 911 are provided on the edge of the first door 910, and an adsorption part 830 is provided on the cabinet 800 corresponding to the position of the magnets 911 for adsorbing the magnets 911. When closing the door, the attraction between the magnets 911 and the adsorption part 830 can attract and fix the first door 910 when it approaches the second door 920, providing initial fixation. This facilitates the alignment of the protruding part 210 with the latch groove 922, and also allows the pressing block 921 to continuously press the trigger 430. This ensures that when the trigger 430 triggers the detection switch 420, the controller 410 and the drive assembly 300 have sufficient time to respond, allowing the drive assembly 300 to drive the protruding part 210 outward to the latch groove 922, thus achieving the purpose of locking the door. It can be understood that the adsorption part 830 can be directly formed on the cabinet 800, or be part of the cabinet 800, or be a magnetic block installed on the cabinet 800, for use with the magnets 911 for adsorption. The adsorption part 830 can be set at the upper or lower part of the cabinet 800, and the corresponding magnet 911 is set at the upper or lower part of the first door 910.

[0109] To improve the user experience, the magnetic attraction force of magnet 911 is F1, where 10N ≤ F1 ≤ 50N. When the first door 910 is locked, the magnetic attraction force exerted on it by magnet 911 ranges from 10N to 50N. After the lock is unlocked, the user needs to overcome this magnetic attraction force to open the door. In this embodiment, the magnetic attraction force of magnet 911 is set to 27N. This not only ensures the attraction of the first door 910 but also allows the user to open the door with less force, thus improving the user experience. It should be noted that the magnetic attraction force of a single magnet 911 can be measured using a commercially available force gauge. This involves using magnet 911 to attract the test hook of the force gauge, pulling magnet 911 until it detaches from the test hook, thus obtaining the magnitude of the magnetic attraction force. It is understandable that when the first door 910 is closed, the magnet 911 may or may not be attached to the adsorption part 830. When the magnet is attached to the adsorption part 830, the magnet 911 can be made of a magnet with a smaller magnetic attraction force compared to a magnet not attached to the adsorption part 830. For example, if the magnet 911 is attached to the adsorption part 830, the magnetic attraction force of the magnet 911 can be less than or equal to 10N to ensure a good feel for the user when opening the door. If the magnet 911 is not attached to the adsorption part 830, the magnetic attraction force of the magnet 911 can be 50N. Then, after the first door 910 is closed, the magnetic attraction force on the first door 910 is much less than 50N, which can ensure a better opening experience for the user. In this embodiment, the magnet 911 is not attached to the adsorption part 830, so the magnetic attraction force of the magnet can be set to 10N≤F1≤50N.

[0110] Among them, reference Figure 2 and Figure 3The outer side of the housing 100 is provided with a button hole 130 communicating with the mounting cavity 110. The trigger 430 has a pressing post 431 and a limiting section 432. The control component 400 includes a reset device 433. The pressing post 431 is provided with a pressing end 434 extending from the button hole 130 to the outside of the housing 100. The limiting section 432 is located inside the mounting cavity 110 and is connected to the pressing post 431. The reset device 433 is provided on the housing 100 and is used to drive the pressing post 431 to extend to the outside of the housing 100 to the initial position. When the pressing end 434 is not pressed by external force, the reset device 433 pushes the pressing column 431 outward to the initial position, so that the pressing end 434 is placed outside the housing 100, so that it can be pressed by external force, and the closing signal can be fed back to the controller 410, so that the controller 410 can control the drive assembly 300 to drive the extension 210 of the latch assembly 200 to extend to the locked state. The pressing end 434 and the limiting section 432 are located at the two ends of the pressing column 431, respectively; when the reset device 433 pushes the pressing column 431 outward, the limiting section 432 is located inside the housing 100 and abuts against the housing 100, preventing the pressing column 431 from coming out of the button hole 130.

[0111] It should be noted that when the first door 910 is in the locked state, the magnetic attraction force of the magnet 911 must be greater than the reset driving force of the reset device 433 to ensure that the magnet 911 firmly attracts the first door 910. In this embodiment, the reset device 433 is a compression spring with a spring force of F2, where 0.3N ≤ F2 ≤ 3N. Specifically, the spring force of the compression spring is 0.65N. If the spring force is too large, it will affect the user's pressing force, making it difficult for the user to press the first door 910 to the position of the stop edge 923. This makes it difficult for the magnet 911 to attract the first door 910, causing the extension part 210 of the lock body to fail to align with the latch groove 922 of the second door 920, resulting in locking failure. Specifically, when actually selecting the magnet 911 and the spring, the following conditions must be met between F1 and F2. (Unit: N) so that the magnet has sufficient attraction to overcome the spring force of the compression spring. The following are some preferred sets of data: 1. When the spring force of the compression spring is 0.3N, the magnetic attraction force of magnet 911 is 10N; 2. When the spring force of the compression spring is 0.65N, the magnetic attraction force of magnet 911 is 27N; 3. When the spring force of the compression spring is 1N, the magnetic attraction force of magnet 911 is 30N; 4. When the spring force of the compression spring is 1.5N, the magnetic attraction force of magnet 911 is 35N; 5. When the spring force of the compression spring is 3N, the magnetic attraction force of magnet 911 is 50N.

[0112] It should be noted that the signal connection mentioned above can be an electrical connection, a Wi-Fi signal connection, a Bluetooth signal connection, or other connection methods, in order to transmit data signals so that the controller 410 can receive signals and send control signals.

[0113] In summary, the automatic security lock body and security cabinet proposed in this invention have at least the following advantages compared with the prior art:

[0114] Firstly, by setting up a detection switch 420 and a trigger 430, when the safe is closed, the trigger 430 is pressed to trigger the detection switch 420. After receiving the closing signal from the detection switch 420, the controller 410 can control the drive assembly 300 to drive the extension part 210 of the latch assembly 200 to extend to the locking position, thereby achieving the purpose of locking the door. In this way, the user does not need to manually turn the knob or handle when closing the door, thus avoiding the situation where the safe or security cabinet is in an unlocked state due to forgetting to turn the knob or handle, and reducing unnecessary property loss.

[0115] Second: By setting the self-locking limit part 140, the forward rotation amplitude of the rotating lever 320 can be limited, so that the extension part 210 in the locked state will not retract into the mounting cavity 110 under the drive of external force, ensuring that the extension part 210 remains in the locked state, and preventing external force from pushing the extension part 210 back into the mounting cavity 110, thereby achieving the purpose of self-locking and anti-pry.

[0116] Third: By setting a detachable battery compartment 600, the battery compartment 600 can be removed during the transportation of the safe, reducing power consumption. Furthermore, in conjunction with the second input interface 710 of the operation panel 700, the battery compartment 600 can be connected to the lock body from the outside of the door, allowing the lock body to be powered and locked. This ensures the safe can be closed during transportation, saving space and preventing the door 900 from shaking. Additionally, the detached battery compartment 600 can act as a power bank. When the safe is delivered to the user, the user can use the battery compartment 600 from the outside to power the lock body inside the door, eliminating the need for the user to carry an additional power bank, saving time searching for one and improving the user experience.

[0117] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and substitutions without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
