DETAILED DESCRIPTION

[0030] The embodiments of the present application are described in detail below in conjunction with the drawings in the embodiments of the present application.

[0031] Please refer to Figure 1-Figure 4 , which is a schematic diagram of the overall structure of the smart unlocking key.

[0032] The present embodiment provides a smart unlocking key, including a lock and a key body that match each other, the lock including a lock core 11, a first locking structure 12, a second locking structure 13 and a lock identification label 14, the lock core 11 is provided with a lock hole 111 along its axial direction; the first locking structure 12 and the second locking structure 13 are sequentially arranged in the lock hole 111 at intervals and staggered along the axial direction of the lock core 11; the lock identification label 14 is arranged inside one end of the lock hole 111 close to the key shell 21;

[0033] The key body includes a key shell 21, an unlocking rod 22, a driving assembly 26, an unlocking identification unit 23 and a main control module 29. The unlocking rod 22 is disposed at one end of the key shell 21, and one end of the unlocking rod 22 is transmission-connected to the driving assembly 26 disposed inside the key shell 21. The unlocking rod 22 is sequentially provided with a first unlocking structure 24 and a second unlocking structure 25 along its axial direction. The first unlocking structure 24 is adapted to the first locking structure 12, and the second unlocking structure 25 is adapted to the second locking structure 13.

[0034] The unlocking identification unit 23 is disposed at one end of the key housing 21 close to the lock and is paired with the lock identification tag 14 , and the unlocking identification unit 23 is electrically connected to the main control module 29 .

[0035] Next, a smart unlocking key according to this exemplary embodiment will be further described.

[0036] In some embodiments, the lock core 11 is provided with a lock hole 111 along its axial direction, and the first locking structure 12 and the second locking structure 13 are sequentially arranged in the lock hole 111 at intervals and offsets along the axial direction of the lock core 11. The first locking structure 12 and the second locking structure 13 can realize double locking of the lock core 11. The unlocking rod 22 is arranged at one end of the key shell 21, and one end of the unlocking rod 22 is connected to the driving assembly 26 arranged inside the key shell 21. The unlocking rod 22 can be driven to rotate by the driving assembly 26, thereby realizing unlocking without manual rotation. The unlocking rod 22 is sequentially provided with a first unlocking structure 24 and a second unlocking structure 25 along its axial direction; the first unlocking structure 24 is adapted to the first locking structure 12, and the second unlocking structure 25 is adapted to the second locking structure 13. When the unlocking rod 22 is inserted into the lock hole 111, the first locking structure 12 and the second locking structure 13 can be unlocked by rotating the unlocking rod 22. The two staggered locking structures can be unlocked from different angles during unlocking, thereby increasing the complexity of unlocking and further improving the security of unlocking.

[0037] In some embodiments, the lock identification tag 14 is disposed inside one end of the key hole 111 close to the key shell 21. The unlock identification unit 23 is disposed at one end of the key shell 21 close to the lock and is paired with the lock identification tag 14, and the unlock identification unit 23 is electrically connected to the main control module 29. When the unlocking rod 22 is inserted into the lock hole 111, the unlock identification unit 23 identifies and pairs with the lock identification tag 14. When the pairing is successful, the identification information is transmitted to the main control module 29, and the main control module 29 starts the driving component 26. Through the above design, the lock and the key body have higher security, and the unlocking can be performed only after the pairing is successful, which can prevent other keys from opening the lock by mistake and causing equipment loss.

[0038] As a preferred embodiment, when the unlocking rod 22 rotates at a first angle, the first unlocking structure 24 unlocks the first locking structure 12, and when the unlocking rod 22 rotates at a second angle, the second unlocking structure 25 unlocks the second locking structure 13. By setting two different angles for unlocking, specifically, different buttons can be set on the key shell 21, or different keying modes of a button can be set for unlocking, which can greatly improve the unlocking security and prevent others from accidentally taking the key to unlock.

[0039] As a preferred embodiment, the above-mentioned first locking structure 12 includes a first locking plate 121 and a first spring 122. The first locking plate 121 is laterally movably arranged in the lock core 11, and one end of the first locking plate 121 passes through a first through hole 112 opened on one side of the lock core 11 in the locked state to be locked by the first locking plate 121. When unlocking, the first locking plate 121 is driven to retreat into the first through hole 112 to achieve unlocking.

[0040] The above-mentioned first lock plate 121 is located above the lock hole 111, and a first limit block 123 is provided on the side of the first lock plate 121 away from the lock hole 111; a first stop block 124 is provided on the side of the first lock plate 121 close to the lock hole 111, and the first stop block 124 and the first limit block 123 are respectively arranged close to the two ends of the first lock plate 121, wherein the first limit block 123 is close to the first through hole 112; the above-mentioned first spring 122 is arranged on the inner side of the lock core 11 close to the first through hole 112, and one end of the first spring 122 abuts against the first limit block 123, and the other end of the first spring 122 abuts against the inner wall of the lock core 11.

[0041] The first stopper 124 is adapted to be matched with the first unlocking structure 24 of the unlocking rod 22, so that the first unlocking structure 24 can push the first stopper 124 to move away from the first through hole 112, thereby driving the first lock plate 121 to move. The first limit block 123 abuts against the first spring 122, and is used to compress the first spring 122 when the first lock plate 121 moves laterally. When the first unlocking structure 24 is pushed out of the lock hole 111, the first lock plate 121 is reset under the reset action of the first spring 122 to achieve locking.

[0042] As a preferred embodiment, the above-mentioned second locking structure 13 includes a second lock plate 131 and a second spring 132. The second lock plate 131 is vertically movably arranged in the lock core 11, and one end of the second lock plate 131 passes through a second through hole 113 opened on one side of the lock core 11 in the locked state to be locked by the second lock plate 131. When unlocking, the second lock plate 131 is driven to retreat into the second through hole 113 to achieve unlocking; cooperating with the first lock plate 121, a double locking effect of the lock core 11 is achieved, thereby improving the locking safety.

[0043] The above-mentioned second lock plate 131 is located on a horizontal side of the lock hole 111, and a second limit block 133 is provided on the side of the second lock plate 131 away from the lock hole 111; a second stop block 134 is provided on the side of the second lock plate 131 close to the lock hole 111, and the second stop block 134 and the second limit block 133 are respectively arranged close to the two ends of the second lock plate 131, wherein the second limit block 133 is close to the second through hole 113; the second spring 132 is arranged on the inner side of the lock core 11 close to the second through hole 113, and one end of the second spring 132 abuts against the second limit block 133, and the other end of the second spring 132 abuts against the inner wall of the lock core 11.

[0044] Similarly, the second stopper 134 is adapted to be matched with the second unlocking structure 25 of the unlocking rod 22, so that the second unlocking structure 25 can push the second stopper 134 to move away from the second through hole 113, thereby driving the second lock plate 131 to move. The second limit block 133 abuts against the second spring 132, and is used to compress the second spring 132 when the second lock plate 131 moves vertically. When the second unlocking structure 25 is pushed out of the lock hole 111, the second lock plate 131 is reset under the reset action of the second spring 132 to achieve locking.

[0045] As a preferred embodiment, the first unlocking structure 24 includes a first semi-circular block 241 disposed on the unlocking rod 22, and the second unlocking structure 25 includes a second semi-circular block 251 disposed on the unlocking rod 22; the first semi-circular block 241 and the second semi-circular block 251 are disposed opposite to each other; the first semi-circular block 241 and the second semi-circular block 251 are respectively in contact with the first block 124 and the second block 134 in the unlocking state. By disposing the first semi-circular block and the second semi-circular block 251 along the axial direction of the unlocking rod 22 and disposing them opposite to each other, when the two semi-circular blocks are rotated to unlock, the rotational spacings between the first block 124 and the second block 134 are different, and thus the rotation angles of the two blocks are different to achieve unlocking. And by being set to a semi-arc shape with a longer arc length, when the semi-arc block pushes the block to unlock, it can be pushed until the locking plate retracts into the through hole, thereby achieving unlocking; at the same time, when the first semi-arc block pushes the first block 124 to unlock, the unlocking rod 22 continues to be rotated to the second angle to unlock the second locking structure 13, which can avoid separation between the first semi-arc block and the first block 124, thereby avoiding the first locking structure 12 from being accidentally re-locked, resulting in the ultimate inability to unlock.

[0046] As a preferred embodiment, the width of the relative position between the lock core 11 and the first locking structure 12 is smaller than the width of the relative position between the lock core 11 and the second locking structure 13. Since the first locking structure 12 and the second locking structure 13 are respectively arranged horizontally and vertically, the volumes occupied by the first locking structure 12 and the second locking structure 13 in the circumferential direction of the lock core 11 are different, so the lock core 11 is arranged in the above shape. The lock core 11 is provided with holes for the first lock plate 121 and the second lock plate 131 to move, holes for the first spring 122 and the second spring 132 to retract, and holes for the unlocking rod 22 to move.

[0047] Furthermore, a shell is provided outside the lock core 11 to protect the lock core 11 .

[0048] As a preferred embodiment, a battery 28 and a wireless charging module 27 are provided in the key shell 21, and the battery 28 is electrically connected to the driving assembly 26, the main control module 29 and the wireless charging module 27. The battery 28 is used to control the functions of various electronic components, and the wireless charging module 27 can wirelessly charge the battery 28 to improve practicality.

[0049] As a preferred embodiment, the driving assembly 26 includes a motor 261, a driving gear 262 and a driven gear 263. The driving gear 262 is connected to the output end of the motor 261, the driven gear 263 is meshed with the driving gear 262, and the unlocking lever 22 is fixed on the central axis of the driven gear 263. The driving gear 262 is driven by the motor 261 to rotate, the driving gear 262 drives the driven gear 263 to rotate, and the driven gear 263 drives the unlocking lever 22 to rotate.

[0050] As a preferred embodiment, the key shell 21 includes an upper shell 211 and a lower shell 212, which are buckled and connected to each other; the upper shell 211 is provided with at least one unlocking button 213, which is electrically connected to the main control module 29. The unlocking button 213 is used to control the drive motor 261, that is, when unlocking, the first locking structure 12 can be unlocked by pressing the unlocking button 213 once, and the second locking structure 13 can be unlocked by pressing the unlocking button 213 twice. Other forms of pressing methods can also be set. It should be noted that when the unlocking identification unit 23 and the lock identification tag 14 are not paired successfully, pressing the unlocking button 213 is invalid and the motor 261 cannot be started. The control circuit adopts existing technology, such as switching circuits such as relays or transistors.

[0051] As a preferred embodiment, the unlocking identification unit 23 is a reader or an NFC identifier; the lock identification tag 14 is an identification code or an NFC chip. The reader is used to read the identification code information, and the NFC identifier is used to identify the NFC chip information, and sends the information to the main control module 29 after the identification pairing is successful.
