[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] like Figures 1-6 As shown, the smart lock hole cover of this embodiment includes a lock hole cover body 1 and a user key 2. The lock hole cover body 1 is designed to be installed on the front panel of the door lock to cover and protect the lock hole. The lock hole cover body 1 includes a lock base 11 and a cover 12.
[0027] The lock base 11 has a lock hole 111 aligned with the door lock hole and is fixed to the front panel of the door lock. A cover 12 is rotatably connected to the lock base 11 and has a through hole 121. The rotation range of the cover 12 is set such that the through hole 121 can be aligned with or offset from the lock hole 111. When the through hole 121 is aligned with the lock hole 111, the user can insert a key into the lock hole to unlock it; when the through hole 121 is offset from the lock hole 111, the lock hole is blocked by the cover 12, effectively preventing foreign objects from entering and improving security.
[0028] To restrict the rotation of the cover 12, an electronic locking assembly 13 is provided between the lock base 11 and the cover 12. Besides the structure detailed later, this electronic locking assembly 13 can also be a magnetic lock, a motor-driven latch mechanism, or other devices capable of controlling the locking and unlocking states via 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 a spring-loaded pin) disposed on the outer surface of the lock base 11.
[0029] User key 2 is used to control the locking and unlocking states of electronic locking assembly 13. User key 2 contains a power supply assembly 21 (e.g., a button battery), a second circuit board 22, and a second contact 23 (e.g., a spring pin) that are electrically connected to each other. The second contact 23 can mate with the first contact 15 on the keyhole cover body 1.
[0030] When a user needs to unlock the door, the second contact 23 of the user key 2 aligns with the first contact 15 of the lock hole 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 the authentication and unlocking command are transmitted through communication between the second circuit board 22 and the first circuit board 14. Upon receiving the unlocking command, the electronic locking component 13 unlocks the cover 12, allowing the user to rotate the cover 12 to align the through hole 121 with the lock hole 111, thereby inserting the key to open the lock.
[0031] like Figure 1-2As shown in Figure 4, the smart keyhole cover 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 located on opposite sides of the administrator key 3. The third contact 33 can mate with the second contact 23 of the user key 2, and the fourth contact 34 can mate with the first contact 15 of the keyhole cover 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 , 2 As shown, user key 2, administrator key 3, and lock cover body 1 are connected together. Specifically, the second contact 23 of user key 2 is connected to the third contact 33 of administrator key 3, and the fourth contact 34 of administrator key 3 is connected to the first contact 15 of lock cover body 1. At this point, the circuits of the three components form a complete loop. The administrator can add, delete, or perform other management operations on user key 2 by operating the control button 32 on administrator key 3. For example, through a specific button combination, the administrator can add a new user key 2 to the system or disable an existing user key 2.
[0033] The innovation of this intelligent keyhole cover lies in its use of an electronic locking component to control the opening and closing of the cover, and the authorization management through user keys and administrator keys. This eliminates the need for traditional mechanical keys to open the keyhole cover, improving both security and convenience. Compared to traditional mechanical keyhole covers, this invention offers higher security, effectively preventing technical unlocking and malicious damage. Simultaneously, the electronic management method is more convenient; users do not need to carry additional keys to open the keyhole cover, and administrators can easily authorize users, enhancing the user experience.
[0034] Based on the above, this utility model 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 user key 2 has a first protrusion 24 on its back, and a second contact 23 is located on the end face of the first protrusion 24. The first contact 15 is located on the front face of the lock seat 11 of the lock hole cover body 1. The through hole 121 on the cover 12 is not only used to align and offset the lock hole 111, but is also designed to align and offset the first contact 15 as the cover 12 rotates. The shape of the first protrusion 24 is adapted to the shape of the through hole 121, and it can be inserted into the through hole 121 so that the second contact 23 contacts the first contact 15, thereby establishing an electrical connection. This design allows the user to simply insert the user key 2 into the lock hole cover when unlocking, without the need for additional alignment operations, making it more convenient.
[0036] The design of the administrator key 3 has also been improved accordingly. The front of the administrator key 3 has a groove 35, the shape and size of which are designed to accommodate the insertion of the first protrusion 24 of the user key 2. A third contact 33 is located inside the groove 35. When the first protrusion 24 of the user key 2 is inserted into the groove 35, the third contact 33 contacts the second contact 23, establishing an electrical connection. The back of the administrator key 3 has a second protrusion 36 with the same size as the first protrusion 24 of the user key 2. A fourth contact 34 is located on the end face of the second protrusion 36. The second protrusion 36 can be inserted into the through hole 121, allowing the fourth contact 34 to contact the first contact 15, thereby establishing an electrical connection.
[0037] To further enhance the user experience and simplify the docking operation between the user key 2, the administrator key 3, and the lock hole cover body 1, this utility model also introduces a magnetic attraction design. Specifically, the first protrusion 24, the groove 35, the second protrusion 36, and the front end face of the lock base 11 are all equipped with magnetic attracting elements (such as magnets). The magnetic pole directions of these magnetic attracting elements are rationally designed so that the first protrusion 24 can magnetically attract the front end face of the lock base 11 and also can magnetically attract the groove 35; at the same time, the second protrusion 36 can magnetically attract the front end face of the lock base 11.
[0038] This magnetic design allows users to easily unlock or manage keys by simply bringing their key or administrator key near the keyhole cover. The magnetic force guides the key to automatically align and attach it to the correct position, eliminating the need for precise positioning and greatly improving convenience and efficiency. Furthermore, the magnetic connection ensures a more secure bond between the key and the keyhole cover, preventing accidental detachment during operation.
[0039] The structure and working principle of the electronic locking component 13 are described in further detail below in this embodiment.
[0040] The electronic locking assembly 13 includes a locking pin 131 slidably connected to the side of the lock base 11, and a locking groove 122 disposed on the inner wall of the cover 12, into which the free end of the locking pin 131 can be inserted. The locking pin 131 can slide within the guide rail of the lock base 11, and its free end is designed to be able to insert into or disengage from the locking groove 122. When the free end of the locking pin 131 is inserted into the locking groove 122, the cover 12 is locked and cannot be rotated; when the free end of the locking pin 131 disengages from the locking groove 122, the cover 12 is unlocked and can be rotated.
[0041] To drive the locking pin 131 to move inward and outward, a driving device is provided between the locking pin 131 and the locking seat 11. In addition to using an electromagnet as described later, the driving device can also use a motor, electric push rod, or other structures.
[0042] Preferably, the drive device includes a resilient reset member 132 and an electromagnet 133.
[0043] An elastic reset element 132, such as a spring, is disposed between the locking pin 131 and the locking seat 11, and its function is to continuously push the locking pin 131 outward. In the unenergized state, the elastic force of the elastic reset element 132 keeps the free end of the locking pin 131 inserted into the locking groove 122, thereby locking the cover 12.
[0044] An electromagnet 133 is disposed inside the lock base 11, its position corresponding to the lock pin 131. When the user key 2 is connected to the lock hole cover body 1 and authentication is completed, the first circuit board 14 controls the electromagnet 133 to be energized. The energized electromagnet 133 generates magnetic force, attracting the lock pin 131 inward, overcoming the elastic force of the elastic reset member 132, causing the free end of the lock pin 131 to disengage from the lock groove 122, thereby unlocking the cover 12. When the electromagnet 133 is de-energized, the elastic force of the elastic reset member 132 will cause the lock pin 131 to reset, reinsert into the lock groove 122, and lock the cover 12.
[0045] This design makes the electronic locking assembly 13 compact, reliable, and low-power. Meanwhile, the use of the elastic reset element 132 for locking pin reset avoids complex mechanical structures, simplifies the design, and reduces manufacturing costs.
[0046] In order to precisely control the rotation range of the cover 12 so that it can be accurately aligned with the lock hole 111 and the first contact point 15, this embodiment adds a limiting structure.
[0047] The limiting structure includes a limiting hole 123 provided on the cover 12 and a limiting pin 16 provided on the lock seat 11 and capable of extending into the limiting hole 123.
[0048] The limiting hole 123 is not a simple round hole, but an arc-shaped hole set around the rotation center of the cover 12. This arc-shaped hole cooperates with the limiting pin 16 to precisely limit the rotation range of the cover 12.
[0049] Specifically, when the cover 12 rotates clockwise to its limit position, the edge of the limiting hole 123 will contact the limiting pin 16, preventing the cover 12 from continuing to rotate clockwise. At this time, the through hole 121 and the lock hole 111 are precisely aligned, and the user can insert a key to unlock the door.
[0050] When the cover 12 rotates counterclockwise to its limit position, the other edge of the limiting hole 123 will contact the limiting 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 protrusion 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 authentication and unlocking operations.
[0051] The clockwise and counterclockwise directions mentioned above can be interchanged.
[0052] This limiting structure design ensures that when the cover 12 is rotated to its limit position, the through hole 121 is precisely aligned with the lock hole 111 and the first contact point 15, respectively. This avoids situations where the lock cannot be opened or the user's key cannot be connected due to deviations in the rotation angle of the cover 12, thus improving ease of use and reliability. This design also simplifies user operation; users do not need to painstakingly find the alignment position, but only need to rotate the cover to its limit position.
