[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Please see Figure 1-8 A smart combination lock box includes a middle frame assembly, a top cover assembly, and a lock body assembly. The middle frame assembly includes a middle frame body 1, a lock hook control box 2, a lock hook body 3, and a hinge seat 4. The middle frame body 1 has an open bearing cavity on its front side. The top wall of the bearing cavity is also provided with the lock hook control box 2, and the bottom wall of the bearing cavity is also provided with the hinge seat 4. The lock hook body 3 is U-shaped, and the two free ends of the lock hook body 3 pass through the top wall of the middle frame body 1 and are connected to the lock hook control box 2.
[0036] The lock hook body 3 is U-shaped, with its two free ends penetrating the top wall of the middle frame body 1 and connecting to the lock hook control box 2. The lock hook control box 2 has a corresponding mechanical structure that engages with the free ends of the lock hook body 3. The middle frame sealing gasket 16 inside the middle frame body 1 has a storage cavity with an opening on the front for placing items. When the combination lock is closed, the middle frame sealing gasket 16, through its elasticity and tight fit with the surrounding structure, isolates the storage area from the external environment. Its sealing effect is particularly effective in preventing liquid leakage. Whether the combination lock is outdoors and exposed to rain or in other environments where it may come into contact with liquid, liquid is unlikely to penetrate the sealing barrier of the middle frame sealing gasket 16 and enter the storage cavity, thus effectively protecting the stored items from moisture erosion. This solves the problem of traditional combination locks lacking waterproofing in the storage area. The unlocking block of the lock hook control box 2 is inserted into the middle frame sealing gasket 16. The middle frame sealing gasket 16 is elastic; after the top cover assembly separates from the middle frame body 1, pressing the unlocking block allows the lock hook control box 2 to separate from the lock hook body 3.
[0037] In this embodiment, the upper cover assembly includes an upper cover body 5, a main board 6, a power supply box 7, and a controller. The upper cover body 5 is hinged to the hinge seat 4 at its lower part. The controller is also embedded in the front of the upper cover body 5. An installation cavity is provided on the back side of the upper cover body 5. The power supply box 7 for closing the installation cavity is also provided on the back side of the upper cover body 5. The power supply box 7 is L-shaped. The main board 6, which is electrically connected to the power supply box 7, the controller, and the lock body assembly, is also provided in the installation cavity. The upper cover body 5 is hinged to the hinge seat 4 of the middle frame assembly at its lower part. Through this hinge structure, the upper cover can move open and close around the hinge point, realizing convenient opening and closing of the password box, which is convenient for users to store or retrieve items. The controller embedded in the front of the upper cover body 5 integrates a keypad 8 and a fingerprint panel 24. Its working principle is as follows:
[0038] Users can press the buttons on the keypad 8 according to the preset numerical password sequence. After the key input is completed, the keypad 8 will transmit the input password information to the mainboard 6 installed in the rear mounting cavity. The control circuit on the mainboard 6 compares and verifies the input password. If the input password matches the correct password pre-stored in the memory of the mainboard 6, the mainboard 6 will send the corresponding unlocking signal to the drive motor 10 in the lock body assembly to start the unlocking process.
[0039] When a user touches the fingerprint panel 24, the sensor inside the fingerprint panel 24 collects the fingerprint information and transmits it to the motherboard 6. The fingerprint recognition module in the motherboard 6 compares and analyzes the collected fingerprint with previously recorded and stored fingerprint data. If the two match, the motherboard 6 sends an unlock signal to the drive motor 10, which then performs the subsequent unlocking action. This fingerprint unlocking method, utilizing biometric technology and relying on each person's unique fingerprint characteristics, is not only convenient and fast but also highly secure. It also provides a different unlocking method for password boxes than traditional single password input, increasing the fault tolerance of unlocking and avoiding the problem of being unable to open the password box due to forgotten passwords.
[0040] The mounting cavity on the back of the top cover body 5 is used to accommodate the motherboard 6. The mounting cavity is closed by an L-shaped power supply box 7. The power supply box 7 protects the internal electronic components, such as the motherboard 6, from external dust and impacts, and also provides integrity to the overall appearance of the top cover assembly. The motherboard 6, as the core control component, is electrically connected to the power supply box 7 and the controller. It is responsible for coordinating signal transmission and power supply between various electronic components, as well as the control logic processing of the entire password box function. For example, it controls the drive motor 10 to operate based on the unlock signal from the controller, or manages the power supply of the power supply box 7 to various components based on the power level.
[0041] The flanges 19 on both sides of the top cover body 5 cooperate with the corresponding notches on the middle frame body 1. When the password box is closed, the flanges 19 are embedded in the notches, increasing the contact area between the top cover assembly and the middle frame assembly, making them fit more tightly and improving the overall sealing performance. This prevents external liquids, dust, etc. from entering the password box from the side gaps, further enhancing the protective performance of the password box. A set of through holes on the flanges 19, which pass through the mounting cavity, are used to bring out the USB interface on the motherboard 6, making it convenient for external charging devices to charge the password box. The rubber plugs 20 block the through holes when not charging, preventing dust, moisture, etc. from entering the mounting cavity through the through holes and affecting the normal operation of electronic components.
[0042] In this embodiment, the lock body assembly includes a lock body box 9, a drive motor 10, a main bolt body 11, a main bolt spring 12, a first lever 13, and a lock cylinder shaft 14. The upper part of the power supply box 7 also houses the lock body box 9. The drive motor 10, the main bolt spring 12, the first lever 13, and the lock cylinder shaft 14 are disposed inside the lock body box 9. The main bolt spring 12 is disposed near the hinge seat 4 inside the lock body box 9. The main bolt body 11 passes through the lock body box 9 and is connected to the main bolt spring 12. The output end of the drive motor 10 is provided with a lock cylinder shaft 14 with an eccentric shaft. A first lever 13 that contacts the lock cylinder shaft 14 is also disposed on one side of the main bolt body 11. A main bolt through hole adapted to the main bolt body 11 is also disposed on the upper part of the upper cover body 5. A latch 15 is also provided below the top wall of the middle frame body 1. The main tongue body 11 is engaged with the latch 15. In the normal closed state of the password box, the main tongue body 11 is connected to the lock body box 9 below through the main tongue spring 12. The main tongue spring 12 is in a naturally extended state, so that the main tongue body 11 extends upward under the action of the spring force, passes through the main tongue through hole on the upper cover body 5, and engages with the latch 15 below the top wall of the middle frame body 1, forming the first locking, ensuring that the upper cover assembly is tightly fixed on the middle frame assembly, preventing the upper cover from being opened accidentally. When unlocking is required, if the unlocking operation is triggered by the controller (correct password input on the button panel 8 or successful fingerprint recognition on the fingerprint panel 24), the main board 6 receives the corresponding correct unlocking signal and sends a control command to the drive motor 10 in the lock body assembly. After receiving the command, the drive motor 10 starts to run, and the lock cylinder shaft 14 with an eccentric shaft set at its output end rotates accordingly. During the rotation of the lock cylinder shaft 14, it will apply an external force to the main tongue body 11 by contacting the first lever 13 on one side of the main tongue body 11, causing the main tongue body 11 to retract downward against the elastic force of the main tongue spring 12 and disengage from the latch 15.
[0043] In actual use, when the main tongue body 11 is unlocked, the upper cover body 5 may separate directly from the middle frame body 1, causing materials to fall out. Therefore, a secondary lock assembly is provided inside the lock body box 9. This secondary lock assembly includes a secondary tongue spring 17 and a secondary tongue body 18. The upper and lower ends of the secondary tongue spring 17 are connected to the secondary tongue body 18 and the housing of the drive motor 10, respectively. The upper cover body 5 also has a secondary tongue through hole adapted to the secondary tongue body 18. The secondary tongue body 18 engages with the buckle 15. The upper part of the secondary tongue body 18 is also rounded. 8 is also kept in the extended state under the action of the auxiliary tongue spring 17, passing through the auxiliary tongue through hole on the upper cover body 5 and engaging with the buckle 15. The rounded upper part of the auxiliary tongue body 18 facilitates the smooth sliding of the auxiliary tongue body 18 along the edge of the buckle 15 and the engagement action when the upper cover is closed. The auxiliary tongue body 18 and the main tongue body 11 work together to form a double locking mechanism. Since the auxiliary tongue body 18 is rounded, after the main tongue body 11 is unlocked and the upper part of the upper cover body 5 is subjected to external force, the auxiliary tongue body 18 squeezes the auxiliary tongue spring 17 and the buckle 15 to misalign, so that the upper cover body 5 can be hinged around the hinge seat 4.
[0044] In actual use, the flange 19 is also provided with a through hole communicating with the mounting cavity, and the flange 19 is also provided with a rubber plug 20 to close the through hole. A mechanical lock cylinder 22 inserted into another set of through holes is also provided on one side of the lock body box 9. A second lever 23 is provided on the other side of the main tongue body 11. The portion of the mechanical lock cylinder 22 inserted into the lock body box 9 is provided with an eccentric rod that aligns with the second lever 23. The mechanical lock cylinder 22 on one side of the lock body box 9 provides a backup method for emergency unlocking. When encountering electronic malfunctions (such as a dead battery, damaged electronic components, etc.) that prevent normal unlocking via the controller, or in special circumstances such as the user forgetting the password, a compatible key can be inserted into the mechanical lock cylinder 22. The portion of the mechanical lock cylinder 22 inserted into the lock body box 9 is equipped with an eccentric rod that cooperates with the second lever 23 on the other side of the main tongue body 11. When the mechanical lock cylinder 22 is inserted and rotated, the eccentric rod will push the second lever 23, thereby causing the main tongue body 11 to retract against the spring force, realizing manual unlocking. This ensures that the combination box can still be opened under various special circumstances, improving the fault tolerance and practicality of the device.
[0045] In actual use, a light 25 is also provided on the motherboard 6 near the power supply box 7. A transparent window 26 is also provided on the power supply box 7. The light 25 is compatible with the transparent window 26. In a dark environment, when the user triggers a corresponding operation (such as pressing a specific button or automatically triggering when opening a password box; the specific triggering method can be set according to the design), the motherboard 6 will supply power to the light 25, causing it to light up. The transparent window 26 on the power supply box 7 ensures that the light from the light 25 can pass through smoothly.
[0046] In actual use, the middle frame body 1 is also provided with a lock hook rainproof plug 27 that is adapted to the free end of the lock hook body 3. The main tongue body 11 and the auxiliary tongue body 18 are respectively fitted with a main tongue sealing ring 28 and an auxiliary tongue sealing ring 29 to ensure the overall sealing of the equipment. At the same time, according to the requirements, the connection of the corresponding components can be equipped with corresponding sealing rings to ensure the overall sealing of the equipment.
