DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-8 , an intelligent password box, including a middle frame assembly, an upper 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 is provided with a bearing cavity with an opening on the front, the top wall of the bearing cavity is also provided with a lock hook control box 2, the bottom wall of the bearing cavity is also provided with a 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, and its two free ends penetrate the top wall of the middle frame body 1 and are connected to the lock hook control box 2. The lock hook control box 2 is provided with a corresponding mechanical structure inside to engage with the free end of the lock hook body 3, and the middle frame sealing pad 16 is provided inside the middle frame body 1, and its front side has a storage cavity with a front opening for placing items. When the password box is closed, the middle frame sealing pad 16 isolates the storage area from the external environment through its own elasticity and close fit with the surrounding structure. In particular, its sealing effect is reflected in the barrier of liquids. Whether the password box is outdoors and encounters rain or in other environments where it may be exposed to liquids, it is difficult for liquids to break through the sealing line of the middle frame sealing pad 16 and enter the storage cavity, thereby effectively protecting the items stored inside and ensuring that the items are not corroded by water, solving the problem of lack of waterproofing in the storage area of ​​the traditional password box. The unlocking block of the lock hook control box 2 is inserted into the middle frame sealing pad 16, and the middle frame sealing pad 16 is elastic. After the upper cover assembly is separated from the middle frame body 1, the lock hook control box 2 can be separated from the lock hook body 3 by pressing the unlocking block;

[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 lower part of the upper cover body 5 is hinged to the hinge seat 4, and the controller is also embedded in the front of the upper cover body 5. The back side of the upper cover body 5 is provided with an installation cavity, and the back side of the upper cover body 5 is also provided with a power supply box 7 for closing the installation cavity. The power supply box 7 is L-shaped, and a main board 6 electrically connected to the power supply box 7, the controller and the lock body assembly is also provided in the installation cavity. The lower part of the upper cover body 5 is hinged to the hinge seat 4 of the middle frame assembly. Through this hinge structure, the upper cover can be opened and closed around the hinge point to realize convenient opening and closing of the password box, which is convenient for users to store or take out items. The controller embedded in the front of the upper cover body 5 integrates a keypad 8 and a fingerprint panel 24, and its working principle is as follows:

[0038] The user can press keys on the keypad 8 in the sequence of pre-set digital passwords. When the key input is completed, the keypad 8 will transmit the input password information to the mainboard 6 installed in the back 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 a corresponding unlocking signal to the drive motor 10 in the lock body assembly to start the unlocking process.

[0039] When the user's finger touches the fingerprint panel 24, the sensor inside the fingerprint panel 24 will collect the fingerprint information of the finger, and then transmit the fingerprint information to the main board 6. The fingerprint recognition module in the main board 6 will compare and analyze the collected fingerprint with the previously entered and stored fingerprint data. If the two match successfully, the main board 6 will also send an unlocking signal to the drive motor 10, and the drive motor 10 will then perform the subsequent unlocking action. This fingerprint unlocking method using biometric technology, relying on each person's unique fingerprint characteristics, is not only convenient and fast to operate, but also has high security. It also provides a way to unlock the password box that is different from the traditional single password input, increases the fault tolerance of the unlocking, and avoids the problem of being unable to open the password box due to forgetting the password.

[0040] The installation cavity on the back side of the upper cover body 5 is used to accommodate the mainboard 6, and the installation cavity is closed by the L-shaped power supply box 7. The power supply box 7 protects the internal mainboard 6 and other electronic components from external dust, collisions, etc. on the one hand, and also provides integrity for the appearance structure of the entire upper cover assembly on the other hand. As the core control component, the mainboard 6 is electrically connected to the power supply box 7 and the controller, and is responsible for coordinating the signal transmission and power supply between various electronic components and the control logic processing of the entire password box function, such as controlling the operation of the drive motor 10 according to the unlocking signal transmitted by the controller, or managing the power supply of the power supply box 7 to various components according to the power supply situation, etc.;

[0041] The flanges 19 set on the left and right sides of the upper cover body 5 cooperate with the notches on the middle frame body 1 that match them. When the password box is closed, the flanges 19 are embedded in the notches, increasing the contact area between the upper cover assembly and the middle frame assembly, making the two fit more tightly, improving the overall sealing, preventing external liquids, dust, etc. from entering the password box from the side gaps, and further strengthening the protection performance of the password box. A set of through holes set on the flanges 19 that pass through the installation cavity are used to lead out the USB interface on the motherboard 6, which is convenient for external charging devices to charge the password box, and the rubber plug 20 blocks the through holes when not charging to prevent dust, moisture, etc. from entering the installation 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 tongue body 11, a main tongue spring 12, a first paddle 13 and a lock core rotating shaft 14. The lock body box 9 is also provided on the upper part of the power supply box 7. The drive motor 10, the main tongue spring 12, the first paddle 13 and the lock core rotating shaft 14 are provided in the lock body box 9. The main tongue spring 12 is provided at one end of the lock body box 9 near the hinge seat 4. The main tongue body 11 passes through the lock body box 9 below and is connected to the main tongue spring 12. The output end of the drive motor 10 is provided with a lock core rotating shaft 14 with an eccentric shaft. The first paddle 13 in contact with the lock core rotating shaft 14 is also provided on one side of the main tongue body 11. A main tongue through hole adapted to the main tongue body 11 is also provided above the upper cover body 5. A buckle 15 is also provided below the top wall of the middle frame body 1, and the main tongue body 11 is engaged with the buckle 15. When the password box is normally closed, the main tongue body 11 is connected to the lock body box 9 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 elastic force, passes through the main tongue through hole on the upper cover body 5, and engages with the buckle 15 below the top wall of the middle frame body 1, forming the first lock, ensuring that the upper cover assembly is tightly fixed on the middle frame assembly to prevent the upper cover from being accidentally opened. When unlocking is required, if the unlocking operation is triggered by the controller (the keypad 8 enters the correct password or the fingerprint panel 24 recognizes the successful fingerprint), the main board 6 will send a control instruction to the drive motor 10 in the lock body assembly after receiving the corresponding correct unlocking signal. The drive motor 10 starts to operate after receiving the instruction, and the lock core shaft 14 with an eccentric shaft arranged at its output end rotates accordingly. During the rotation of the lock core shaft 14, the first paddle 13 on one side of the main tongue body 11 is contacted to exert an external force on the main tongue body 11, so that the main tongue body 11 overcomes the elastic force of the main tongue spring 12 and retracts downward, thus disengaging from the locking state with the buckle 15.

[0043] In actual use of the above structure, when the main tongue body 11 is unlocked, the upper cover body 5 is easily separated from the middle frame body 1, causing the material to fall. For this reason, a secondary lock assembly is also provided in the lock body box 9, and the 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 respectively connected to the secondary tongue body 18 and the housing of the driving motor 10. The upper cover body 5 is also provided with a secondary tongue through hole adapted to the secondary tongue body 18. The secondary tongue body 18 is snap-fitted with the buckle 15. The upper part of the secondary tongue body 18 is also provided with a chamfer. The secondary tongue body 1 8 is also kept in the extended state under the action of the auxiliary tongue spring 17, passes through the auxiliary tongue through hole on the upper cover body 5 and is engaged with the buckle 15. The chamfered portion of the auxiliary tongue body 18 is convenient for the auxiliary tongue body 18 to smoothly slide along the edge of the buckle 15 and complete the engaging 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 provided with a chamfered portion, after the main tongue body 11 is unlocked and an external force is applied to the upper part of the upper cover body 5, the auxiliary tongue body 18 squeezes the auxiliary tongue spring 17 and the buckle 15 to be misaligned, 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 that penetrates the installation cavity, and the flange 19 is also provided with a rubber plug 20 that closes the through hole. A mechanical lock core 22 inserted into another set of through holes is also provided on one side of the lock body box 9, and a second paddle 23 is provided on the other side of the main tongue body 11. The part of the mechanical lock core 22 inserted into the lock body box 9 is provided with an eccentric rod with the second paddle 23. The mechanical lock core 22 provided on one side of the lock body box 9 provides a backup method for emergency unlocking. When encountering a failure of the electronic part (such as a dead battery, damaged electronic components, etc.) that makes it impossible to unlock normally through the controller, or when the user forgets the password and other special circumstances, an adapted key can be used to insert the mechanical lock core 22. The part of the mechanical lock core 22 inserted into the lock body box 9 is provided with an eccentric rod that cooperates with the second paddle 23 on the other side of the main tongue body 11. When the mechanical lock core 22 is inserted and rotated, the eccentric rod will push the second paddle 23, thereby driving the main tongue body 11 to retract to overcome the spring force, thereby realizing manual unlocking and ensuring that the password box can still be opened under various special circumstances, thereby improving the fault tolerance and practicality of the device.

[0045] In actual use, the mainboard 6 is also provided with a lighting lamp 25 at one end near the power supply box 7, and the power supply box 7 is also provided with a transparent window 26, and the lighting lamp 25 is adapted to the transparent window 26. The lighting lamp 25 provided at one end of the mainboard 6 near the power supply box 7, in a dark environment, when the user triggers a corresponding operation (such as automatically triggering when pressing a specific button or opening a password box, etc., the specific triggering method can be set according to the design), the mainboard 6 will supply power to the lighting lamp 25, so that the lighting lamp 25 lights up. The transparent window 26 provided on the power supply box 7 ensures that the light of the lighting lamp 25 can be smoothly transmitted.

[0046] During actual use, the middle frame body 1 is also provided with a lock hook rain plug 27 which is compatible with the free end of the lock hook body 3. The main tongue body 11 and the auxiliary tongue body 18 are respectively provided 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 needs, corresponding sealing rings can be assembled at the connection points of corresponding components to ensure the overall sealing of the equipment.
