[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figure 1-Figure 6 As shown, the smart escutcheon of this embodiment includes an escutcheon body 1 and a user key 2. The escutcheon body 1 is designed to be installed on the front panel of a door lock to cover and protect the door lock hole. The escutcheon body 1 includes a lock seat 11 and a blocking cover 12.

[0027] The lock base 11 is provided with a lock hole 111 aligned with the door lock hole and fixed to the front panel of the door lock. The blocking cover 12 is rotatably connected to the lock base 11 and is provided with a through hole 121. The rotation range of the blocking cover 12 is set so that the through hole 121 can be aligned with or staggered from the lock hole 111. When the through hole 121 is aligned with the lock hole 111, the user can insert the key into the lock hole to unlock the door; when the through hole 121 is staggered from the lock hole 111, the lock hole is blocked by the blocking cover 12, effectively preventing foreign objects from entering and improving safety.

[0028] In order to limit the rotation of the blocking cover 12, an electronic locking assembly 13 is provided between the lock base 11 and the blocking cover 12. In addition to the structure described in detail below, the electronic locking assembly 13 can also be a magnetic lock, a motor-driven latch mechanism, or other devices that can control the locking and unlocking states through electrical signals. The electronic locking assembly 13 is electrically connected to a first circuit board 14 disposed inside the lock base 11 and a first contact 15 (such as an elastic pin) disposed on the outer surface of the lock base 11.

[0029] The user key 2 is used to control the locking and unlocking states of the electronic locking assembly 13. The user key 2 is provided with a power supply assembly 21 (such as a button battery), a second circuit board 22 and a second contact 23 (such as an elastic pin) which are electrically connected to each other. The second contact 23 can be connected to the first contact 15 on the escutcheon body 1.

[0030] When the user needs to unlock the door, the second contact 23 of the user key 2 is connected to the first contact 15 of the keyhole cover body 1. At this time, the power supply component 21 of the user key 2 supplies power to the first circuit board 14 and the electronic locking component 13, and completes the identity authentication and transmission of the unlocking command through the communication between the second circuit board 22 and the first circuit board 14. After receiving the unlocking command, the electronic locking component 13 unlocks the cover 12, and the user can rotate the cover 12 to align the through hole 121 with the lock hole 111, so as to insert the key to unlock the door.

[0031] like Figure 1-2 As shown in Figures 4 and 5, the smart escutcheon of this embodiment also includes an administrator key 3 for managing user keys 2, such as adding or deleting authorized user keys. The administrator key 3 includes a third circuit board 31, a control button 32, and a third contact 33 and a fourth contact 34, which are electrically connected to each other, and are respectively located on the front and back sides of the administrator key 3. The third contact 33 can be docked with the second contact 23 of the user key 2, and the fourth contact 34 can be docked with the first contact 15 of the escutcheon body 1. Furthermore, a micro switch 321 is provided at the control button 32, and the micro switch 321 is electrically connected to the third circuit board 31.

[0032] When user key management is required, such as Figure 1 , 2As shown, the user key 2, the administrator key 3 and the escutcheon body 1 are connected together. The specific operation is: the second contact 23 of the user key 2 is connected to the third contact 33 of the administrator key 3, and the fourth contact 34 of the administrator key 3 is connected to the first contact 15 of the escutcheon body 1. At this time, the circuits of the three components form a complete loop. The administrator can add, delete or perform other management operations on the user key 2 by operating the control button 32 on the administrator key 3. For example, through a specific key combination, the administrator can add a new user key 2 to the system, or invalidate an existing user key 2.

[0033] The innovation of the smart keyhole cover of the present invention lies in the use of an electronic locking component to control the opening and closing of the cover, and the authorization management is realized through the user key and the administrator key, without the need for a traditional mechanical key to open the keyhole cover, thereby improving security and convenience. Compared with the traditional mechanical keyhole cover, the present invention has higher security and can effectively prevent technical unlocking and malicious damage; at the same time, the electronic management method is also more convenient, and the user does not need to carry an additional key to open the keyhole cover, and the administrator can also easily manage the authorization of the user, thereby improving the user experience.

[0034] On the basis of the above, the present invention further optimizes the connection method between the user key, the administrator key and the keyhole cover body, thereby improving the user experience.

[0035] Specifically, the back of the user key 2 is designed with a first boss 24, and the second contact 23 is arranged on the end face of the first boss 24. The first contact 15 is arranged on the front end face of the lock seat 11 of the keyhole cover body 1. The through hole 121 on the blocking cover 12 is not only used to align and stagger the lock hole 111, but also designed to align and stagger the first contact 15 as the blocking cover 12 rotates. The shape of the first boss 24 is adapted to the shape of the through hole 121, and can be inserted into the through hole 121, so that the second contact 23 contacts the first contact 15, thereby establishing an electrical connection. Such a design allows the user to only insert the user key 2 into the keyhole cover when unlocking, without the need for additional alignment operations, which is more convenient.

[0036] The design of the administrator key 3 has also been improved accordingly. A groove 35 is provided on the front of the administrator key 3, and the shape and size of the groove 35 are designed to accommodate the insertion of the first boss 24 of the user key 2. The third contact 33 is arranged inside the groove 35. When the first boss 24 of the user key 2 is inserted into the groove 35, the third contact 33 contacts the second contact 23 to establish an electrical connection. A second boss 36 having the same size as the first boss 24 of the user key 2 is provided on the back of the administrator key 3, and the fourth contact 34 is arranged on the end face of the second boss 36. The second boss 36 can be inserted into the through hole 121, so that the fourth contact 34 contacts the first contact 15, thereby establishing an electrical connection.

[0037] In order to further improve the user experience and simplify the docking operation between the user key 2, the administrator key 3 and the keyhole cover body 1, the present invention also introduces a magnetic attraction design. Specifically, the first boss 24, the groove 35, the second boss 36 and the front end surface of the lock seat 11 are all provided with magnetic attraction parts (for example, magnets are installed). The magnetic pole directions of these magnetic attraction parts are reasonably designed so that the first boss 24 can be magnetically attracted to the front end surface of the lock seat 11, and can also be magnetically attracted to the groove 35; at the same time, the second boss 36 can be magnetically attracted to the front end surface of the lock seat 11.

[0038] With this magnetic design, when users are unlocking or managing user keys, they only need to bring the user key or administrator key close to the keyhole cover, and the magnetic force will guide the key to automatically align and adsorb to the correct position without the need for precise positioning operations, greatly improving the convenience and efficiency of operations. In addition, the magnetic connection also makes the connection between the key and the keyhole cover more stable, avoiding accidental falling off during operation.

[0039] The structure and working principle of the electronic locking assembly 13 are further described in detail in the following embodiment.

[0040] The specific structure of the electronic locking assembly 13 includes a lock pin 131 slidably connected to the side of the lock base 11, and a lock slot 122 provided on the inner side wall of the blocking cover 12 and capable of inserting the free end of the lock pin 131. The lock pin 131 can slide in the guide rail of the lock base 11, and its free end is designed to be inserted into or out of the lock slot 122. When the free end of the lock pin 131 is inserted into the lock slot 122, the blocking cover 12 is locked and cannot rotate; when the free end of the lock pin 131 is out of the lock slot 122, the blocking cover 12 is unlocked and can rotate.

[0041] In order to drive the lock pin 131 to move inward and outward, a driving device is provided between the lock pin 131 and the lock seat 11. In addition to the electromagnet described below, the driving device may also use a motor, an electric push rod, and other structures.

[0042] Preferably, the driving device includes an elastic reset member 132 and an electromagnet 133 .

[0043] The elastic reset member 132, such as a spring, is disposed between the lock pin 131 and the lock seat 11 to continuously press the lock pin 131 outward. In the non-powered state, the elastic force of the elastic reset member 132 keeps the free end of the lock pin 131 inserted into the lock slot 122, thereby locking the blocking cover 12.

[0044] The electromagnet 133 is arranged inside the lock seat 11, and its position corresponds to the lock pin 131. When the user key 2 is connected to the keyhole cover body 1 and the identity verification is completed, the first circuit board 14 controls the electromagnet 133 to be energized. The electromagnet 133 after being energized generates a magnetic force, which attracts the lock pin 131 inward, overcomes the elastic force of the elastic reset member 132, and causes the free end of the lock pin 131 to be disengaged from the lock slot 122, thereby unlocking the cover 12. When the electromagnet 133 is powered off, the elastic force of the elastic reset member 132 causes the lock pin 131 to be reset, reinserted into the lock slot 122, and lock the cover 12.

[0045] This design makes the electronic locking assembly 13 compact, reliable, and low in power consumption. At the same time, the elastic reset member 132 is used to reset the lock pin, which avoids a complex mechanical structure, simplifies the design, and reduces the manufacturing cost.

[0046] In order to precisely control the rotation range of the blocking cover 12 so that it can be accurately aligned with the locking hole 111 and the first contact 15 , a limiting structure is added in this embodiment.

[0047] The limiting structure includes a limiting hole 123 disposed on the blocking cover 12 and a limiting pin 16 disposed on the lock base 11 and capable of extending into the limiting hole 123 .

[0048] The limiting hole 123 is not a simple circular hole, but an arc hole arranged around the rotation center of the blocking cover 12. This arc hole cooperates with the limiting pin 16 to accurately limit the rotation range of the blocking cover 12.

[0049] Specifically, when the blocking cover 12 rotates to the limit position in the clockwise direction, the edge of the limiting hole 123 contacts the limiting pin 16, preventing the blocking cover 12 from continuing to rotate clockwise. At this time, the through hole 121 is precisely aligned with the lock hole 111, and the user can insert the key to unlock the lock.

[0050] When the cover 12 rotates counterclockwise to the limit position, the other edge of the limit hole 123 contacts the limit pin 16, preventing the cover 12 from continuing to rotate counterclockwise. At this time, the through hole 121 is precisely aligned with the first contact 15, and the user can insert the first boss 24 of the user key 2 into the through hole 121, so that the second contact 23 contacts the first contact 15, completing the circuit connection and performing identity authentication and unlocking operations.

[0051] The above-mentioned clockwise and counterclockwise directions can be reversed.

[0052] This limiting structure design ensures that when the cover 12 is rotated to the limit position, the through hole 121 can be accurately aligned with the lock hole 111 and the first contact 15, thereby avoiding the situation where the cover 12 cannot be normally unlocked or connected to the user's key due to the rotation angle deviation, thereby improving the convenience and reliability of use. This design also simplifies user operation, and the user does not need to laboriously find the alignment position, but only needs to rotate the cover to the limit position.
