Description

Technical Field

[0001] This invention relates to the field of safe manufacturing technology, specifically to an electromechanical integrated intelligent control safe. Background Technology

[0002] Safes are generally used to store valuables such as cash, gold, and jewelry. Traditional safes mostly use mechanical locks, but with the development of electronic locks (fingerprint locks, combination locks, etc.), some safes on the market now use electronic locks for unlocking.

[0003] These safes with electronic locks are mainly divided into two categories. One type combines electromagnetic locks and mechanical locks. The electromagnetic lock restricts the movement of the locking rod assembly, and fingerprints or passwords are used to unlock the electromagnetic lock, thereby eliminating the restriction on the movement of the locking rod assembly. The handle then drives the locking rod assembly to unlock the safe. In essence, the mechanical lock is still used to lock the safe. In the event of a power outage, the electromagnetic lock of this type of safe can be easily opened, and once the electromagnetic lock is opened, the safe door can be opened, resulting in poor security. Another type uses an electronic lock to control a motor, which in turn drives the movement of a locking rod assembly to unlock the safe. These safes typically include an emergency unlocking mechanism for special situations (battery replacement, maintenance, etc.). For example, patent application CN120625988A, entitled "A High-Reliability Safe Locking Component and Safe," discloses a safe structure including a drive motor and a bolt assembly; it also includes a mechanical lock assembly for providing emergency unlocking functionality. The mechanical lock assembly includes an emergency lock body, a transmission rod assembly, and a motor mounting plate. One end of the transmission rod assembly is connected to the motor mounting plate, and when the emergency lock body is in motion, it transmits power to the motor mounting plate, causing the motor mounting plate to move laterally. However, this emergency unlocking structure lacks protective measures; the emergency lock can be opened using a master key, mechanical unlocking, etc., thereby opening the safe door and affecting its security. Therefore, its structure needs further improvement. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned deficiencies and to disclose to the public a mechatronic intelligent control safe with a reasonable structure and strong security.

[0005] The technical solution of this invention is implemented as follows:

[0006] An electromechanical integrated intelligent control safe includes a cabinet door hinged to the cabinet body, an unlocking device on the cabinet door, and a motor on the cabinet door connected to the unlocking device. The motor drives a main locking rod mounting plate to move horizontally, and the main locking rod mounting plate is linked with auxiliary locking rod mounting plates located on the upper and lower sides of the cabinet door. An electromagnetic lock assembly connected to the unlocking device is provided on the cabinet door, and the electromagnetic lock assembly has a locking tongue. The main locking rod mounting plate has a protrusion that cooperates with the locking tongue. An electromagnetic lock hole is provided on the cabinet door at the corresponding position of the electromagnetic lock assembly. An emergency mechanical lock is provided on the main locking rod mounting plate, and an emergency lock hole is provided on the cabinet door. A blocking component is connected to the electromagnetic lock assembly to block the emergency lock hole when the electromagnetic lock assembly is locked.

[0007] Further optimization measures for this technical solution are as follows:

[0008] As an improvement, the electromagnetic lock assembly includes a lock cylinder and a lock head that are linked together. The bolt is disposed on the lock head, a lock cylinder rod is disposed inside the lock cylinder, and a lock head rod is disposed on the lock head. A linkage rod is disposed between the lock cylinder rod and the lock head rod. The end of the lock head rod away from the linkage rod is connected to the bolt, and a blocking member is connected to the end of the lock cylinder rod away from the linkage rod. The electromagnetic lock assembly adopts a separate structure for the lock cylinder and the lock head, which makes the structure more stable, reliable, and lower in cost.

[0009] As an improvement, the emergency mechanical lock includes a lock body, a limiting block is hinged to the lock body, the limiting block is limited to cooperate with the main lock rod mounting plate, the emergency lock hole is set at the position corresponding to the limiting block, the emergency mechanical lock also includes a lever that cooperates with the main lock rod mounting plate, and a connecting piece with a non-circular cross section is provided on the lever facing the emergency lock hole.

[0010] As an improvement, a screw is connected to the motor, a screw seat is mounted on the main locking rod mounting plate, the screw is screwed to the screw seat, the limiting block abuts against the screw seat, and a sliding groove is provided on the main locking rod mounting plate at the position corresponding to the screw seat.

[0011] As an improvement, the main locking rod mounting plate and the auxiliary locking rod mounting plates on the upper and lower sides are driven by the motor to move synchronously. The specific structure of the linkage between the main locking rod mounting plate and the auxiliary locking rod mounting plates on the upper and lower sides is as follows: a connecting plate and a linkage turntable are respectively provided between the main locking rod mounting plate and the auxiliary locking rod mounting plate. The linkage turntable is rotatably connected to the cabinet door. A first linkage rod and a second linkage rod are respectively provided on both sides of the linkage turntable. One end of the connecting plate is fixed to the main locking rod mounting plate, and the other end is vertically provided with a first linkage groove adapted to the first linkage rod. The auxiliary locking rod mounting plate is horizontally provided with a second linkage groove adapted to the second linkage rod.

[0012] As an improvement, the main locking rod mounting plate is provided with a horizontal guide groove, and the cabinet door is provided with a guide post, which is placed in the corresponding guide groove. The cooperation between the guide groove and the guide post allows the main locking rod mounting plate to move horizontally in a set direction.

[0013] As an improvement, a limit switch is provided on the cabinet door, and a protrusion that cooperates with the limit switch is provided on the main locking rod mounting plate. The cooperation between the limit switch and the protrusion limits the travel of the main locking rod mounting plate.

[0014] As an improvement, a first outer cover is provided on the main locking rod mounting plate, a second outer cover is provided on the auxiliary locking rod mounting plate, and a third outer cover is provided on the electromagnetic lock assembly. The outer cover protects the internal components and also blocks some dust, thus extending their service life.

[0015] As an improvement, the unlocking device can be a fingerprint device or a password device.

[0016] As an improvement, the motor is a stepper motor.

[0017] The advantages of this invention compared to the prior art are:

[0018] This invention discloses an electromechanical integrated intelligent control safe with a reasonable structure. It activates a motor via an unlocking device, which drives the main lock rod mounting plate to move, thus unlocking the safe. Furthermore, the safe incorporates an emergency unlocking structure consisting of an electromagnetic lock assembly and an emergency mechanical lock. The electromagnetic lock assembly has a blocking component that obstructs the emergency lock's keyhole when the electromagnetic lock assembly is locked. For emergency unlocking, the electromagnetic lock must first be opened, causing the bolt to retract and release the obstruction to the main lock rod mounting plate. Simultaneously, the blocking component is removed, allowing the emergency key to be inserted into the emergency lock's keyhole. This multi-layered emergency unlocking structure significantly improves the safe's resistance to technical opening, further enhancing its security. Attached Figure Description

[0035] like Figures 1 to 10 As shown, an electromechanical integrated intelligent control safe includes a cabinet door 12 hinged to a cabinet body 11. The cabinet door 12 is equipped with an unlocking device 13 and a motor 2 connected to the unlocking device 13. The motor 2 drives a main locking rod mounting plate 3 to move horizontally. The main locking rod mounting plate 3 is linked with auxiliary locking rod mounting plates 4 located on the upper and lower sides of the cabinet door 12. The cabinet door 12 is equipped with an electromagnetic lock assembly 5 connected to the unlocking device 13. The electromagnetic lock assembly 5 has a locking tongue 5a. The main locking rod mounting plate 3 has a protrusion 31 that cooperates with the locking tongue 5a. The cabinet door 12 has an electromagnetic lock hole 12a corresponding to the position of the electromagnetic lock assembly 5. The main locking rod mounting plate 3 has an emergency mechanical lock 6. The cabinet door 12 has an emergency lock hole 12b. A blocking member 7 is connected to the electromagnetic lock assembly 5, blocking the emergency lock hole 12b when the electromagnetic lock assembly 5 is locked.

[0036] The electromagnetic lock assembly includes a lock cylinder 51 and a lock head 52 that are linked together. The lock tongue 5a is disposed on the lock head 52. The lock cylinder 51 is provided with a lock cylinder rod 51a. The lock head 52 is provided with a lock head rod 52a. A linkage rod 53 is provided between the lock cylinder rod 51a and the lock head rod 52a. The end of the lock head rod 52a away from the linkage rod 53 is connected to the lock tongue 5a. The blocking member 7 is connected to the end of the lock cylinder rod 51a away from the linkage rod 53.

[0037] The emergency mechanical lock 6 includes a lock body 61, a limiting block 62 hinged to the lock body 61, the limiting block 62 engaging with the main lock rod mounting plate 3, the emergency lock hole 12b being positioned corresponding to the limiting block 62, and the emergency mechanical lock 6 also includes a lever 63 engaging with the main lock rod mounting plate 3, with a connecting piece 64 having a non-circular cross-section positioned on the lever 63 opposite the emergency lock hole 12b.

[0038] In this embodiment, the inner cross-section of the connector 64 is hexagonal, and a hexagonal wrench can be used as an emergency key to facilitate operation by maintenance workers.

[0039] The motor 2 is connected to a screw 21, and the main locking rod mounting plate 3 is equipped with a screw seat 32. The screw 21 is screwed to the screw seat 32, and the limiting block 62 abuts against the screw seat 32. The main locking rod mounting plate 3 has a sliding groove 3a at the corresponding position of the screw seat 32. By utilizing the protruding screw seat 32 and the limiting block 62 for cooperation, the screw seat 32 can perform two functions, making the structure simpler and more compact.

[0040] The motor 2 drives the main locking rod mounting plate 3 and the upper and lower auxiliary locking rod mounting plates 4 to move synchronously. The specific structure of the linkage between the main locking rod mounting plate 3 and the upper and lower auxiliary locking rod mounting plates 4 is as follows: a connecting plate 81 and a linkage turntable 82 are respectively provided between the main locking rod mounting plate 3 and the auxiliary locking rod mounting plate 4. The linkage turntable 82 is rotatably connected to the cabinet door 12. A first linkage rod 82a and a second linkage rod 82b are respectively provided on both sides of the linkage turntable 82. One end of the connecting plate 81 is fixed to the main locking rod mounting plate 3, and the other end is vertically provided with a first linkage groove 81a that matches the first linkage rod 82a. The auxiliary locking rod mounting plate 4 is horizontally provided with a second linkage groove 4a that matches the second linkage rod 82b.

[0041] The main locking rod mounting plate 3 is provided with a guide groove 3b in the horizontal direction, and the cabinet door 12 is provided with a guide post 12c, which is placed in the corresponding guide groove 3b. The cooperation between the guide groove 3b and the guide post 12c allows the main locking rod mounting plate 3 to move in a set horizontal direction.

[0042] The cabinet door 12 is equipped with a limit switch 12d, and the main locking rod mounting plate 3 is equipped with a protrusion 33 that cooperates with the limit switch 12d. The limit switch 12d is located on both sides of the protrusion 33. Through the cooperation between the limit switch 12d and the protrusion 33, the travel of the main locking rod mounting plate 3 is limited. When the protrusion 33 touches the limit switch 12d, a control signal is sent to stop the motor 2 from working.

[0043] The main locking rod mounting plate 3 is provided with a first outer cover 91, the auxiliary locking rod mounting plate 4 is provided with a second outer cover 92, and the electromagnetic lock assembly 5 is provided with a third outer cover 93. The outer cover can protect the internal components and block some dust, which is beneficial to improving the service life.

[0044] In this embodiment, the unlocking device 13 is a fingerprint device, but it can also be a password device. As an extension, Internet of Things (IoT) technology can be used, employing a mobile app as the unlocking device 13.

[0045] The motor 2 mentioned is a stepper motor. Using a stepper motor as a power source results in more stable operation and more precise control.

[0046] Working principle:

[0047] The present invention discloses an electromechanical integrated intelligent control safe, which is equipped with a three-sided locking system, including a main locking rod mounting plate 3 and auxiliary locking rod mounting plates 4 on the upper and lower sides. The main locking rod mounting plate 3 is provided with main locking rods 34 at intervals, and the auxiliary locking rod mounting plates 4 are provided with auxiliary locking rods 41 at intervals. The auxiliary locking rod mounting plates 4 on the upper and lower sides are symmetrically arranged.

[0048] When unlocking, the unlocking device 13 sends a control signal to unlock the electromagnetic lock assembly 5, causing the bolt 5a of the electromagnetic lock assembly 5 to retract. At the same time, the unlocking device 13 (fingerprint unlocking, password, etc.) sends a control signal to start the motor 2. The motor 2 drives the screw 21 to rotate. Since the main lock rod mounting plate 3 is restricted to horizontal movement, when the screw 21 rotates, it acts on the screw seat 32 to drive the main lock rod mounting plate 3 to move to the left, and the main lock rod 34 on the main lock rod mounting plate 3 retracts inward. Simultaneously, as the main locking rod mounting plate 3 moves, it drives the connecting plate 81 to move. The first linkage groove 81a on the connecting plate 81 acts on the first linkage rod 82a, thereby driving the linkage turntable 82 to rotate. The second linkage rod 82b on the linkage turntable 82 rotates accordingly. The second linkage rod 82b acts on the second linkage groove 4a on the auxiliary locking rod mounting plate 4, thereby driving the upper auxiliary locking rod mounting plate 4 to move downward (the lower auxiliary locking rod mounting plate 4 moves upward), causing the auxiliary locking rod 41 on the auxiliary locking rod mounting plate 4 to retract inward, thus achieving synchronous retraction of the locking rods on all three sides, completing the unlocking, and the cabinet door 12 can then be opened. This safe adopts a handle-less structure. After unlocking, the cabinet door 12 will be slightly open, at which point the cabinet door 12 can be manually opened. This invention's safe, through a three-sided locking system driven by the motor 2, can achieve handle-less opening of extra-large safes (height ≥ 90cm) and can also achieve semi-automatic opening of heavy-duty safes.

[0049] When locking the safe door, the action steps are the reverse of the unlocking action. That is, motor 2 reverses, driving the main locking rod mounting plate 3 to move to the right. This, through the connecting plate 81 and the linkage turntable 82, drives the upper auxiliary locking rod mounting plate 4 to move upward (and the lower auxiliary locking rod mounting plate 4 to move downward), thereby achieving synchronous extension of the locking rods on all three sides and completing the locking. The three-sided locking structure greatly improves the security of the safe.

[0050] This invention discloses an electromechanical integrated intelligent control safe, which also includes an emergency unlocking structure consisting of an electromagnetic lock assembly 5 and an emergency mechanical lock 6. In an emergency, the electromagnetic lock must be opened first, and then the emergency mechanical lock 6 can be opened. The emergency handling compound clutch opening structure design of the motor-driven safe increases the technical difficulty of opening the safe, further enhancing its anti-theft and security features.

[0051] The specific unlocking method is as follows: First, insert the electromagnetic lock key (the mechanical key used in emergency situations) into the electromagnetic lock hole 12a. Turn the electromagnetic lock key, causing the lock cylinder rod 51a of the lock cylinder 51 to move downwards. The lock cylinder rod 51a, through the linkage rod 53, causes the lock head rod 52a of the lock head 52 to move downwards, thereby retracting the bolt 5a and eliminating the obstruction of the bolt 5a to the protrusion 31 on the main lock rod mounting plate 3. As the lock cylinder rod 51a moves downwards, it also causes the blocking part 7 to move downwards. At this time, the emergency key can be inserted into the emergency lock hole 12b.

[0052] The emergency mechanical lock 6 is operated in two steps. First, as the emergency key is inserted into the emergency lock hole 12b, the emergency key pushes the limiting block 62 inward, causing the limiting block 62 to move away from the screw seat 32, thereby releasing the obstruction of the screw seat 32 by the limiting block 62. Then, the emergency key is turned, which drives the lever 63 to rotate. The lever 63 drives the main lock rod mounting plate 3 to move (the screw seat 32 is in the slide groove 3a and moves relative to the main lock rod mounting plate 3), thereby completing the manual unlocking to meet the needs of emergency unlocking.

[0053] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
