When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0042] like Figure 1-Figure 7 As shown, an electronic lock that can be unlocked by a mechanical emergency key 5 mainly includes: a lock body 1, a locking member 2, an electronic unlocking module 3 and a mechanical unlocking module 4.
[0043] The lock body 1 is provided with a locking member 2, which has a locked position state and an unlocked position state on the lock body 1. The locking member 2 is rotatably arranged in the lock body 1, that is, the locking member 2 is rotatably switched between the locked position state and the unlocked position state. During use, the locking member 2 cooperates with other locking structures, and a through groove is provided on the lock body 1. When the locking member 2 is in the locked position state, the locking block on the locking member 2 extends into the through groove and locks with the locking structure, and the electronic lock is in the locked state; when the locking member 2 is rotated and switched to the unlocked position state, the locking block on the locking member 2 rotates inward and turns away from the through groove, the locking member 2 is no longer locked with the locking structure, and the electronic lock can be unlocked.
[0044] The electronic unlocking module 3 is arranged in the lock body 1, and includes a power supply 30, a motor 31 and a first transmission mechanism 32. The motor 31 is electrically connected to the power supply 30. The first transmission mechanism 32 is connected between the motor 31 and the locking member 2, and the motor 31 can drive the locking member 2 to switch between the locked position state and the unlocked position state through the first transmission mechanism 32. Specifically, the first transmission mechanism 32 includes a worm wheel 322 and a worm 321. The worm 321 is connected to the rotating shaft of the motor 31. The worm wheel 322 is connected to the locking member 2 and is driven by the worm 321. The motor 31 can drive the locking member 2 to rotate through the worm 321 and the worm wheel 322. When electronic unlocking is performed, the power supply 30 supplies power to the motor 31, the motor 31 rotates, drives the worm 321 to rotate, the worm 321 drives the worm wheel 322 to rotate, the worm wheel 322 drives the locking member 2 to rotate, and the locking member 2 rotates to the unlocked position state. During the electronic unlocking process, the lock cylinder 40 in the mechanical unlocking module 4 does not move to avoid affecting the mechanical unlocking. A control circuit board 33 is also provided in the lock body 1. The control circuit board 33 is electrically connected to the motor 31 and the battery, and can control the operation of the motor 31. The lock body 1 has a lock shaft 10 extending vertically outward, and the motor 31 is arranged in the lock shaft 10. The motor 31 is arranged in the lock shaft 10, which can free up the main installation space of the lock body 1 for installing other modules, so that the electronic lock structure is more compact and more conducive to miniaturization. A lock shaft sleeve 13 is provided on the lock shaft 10, and the lock shaft sleeve 13 is detachably connected to the lock body 1. When the electronic lock of this embodiment is used to update an old mechanical lock, the lock shaft sleeve 13 can be removed and the remaining part can be used to replace the lock core of the old mechanical lock.
[0045] In addition to the transmission method of the worm wheel 322 and the worm 321 , the first transmission mechanism 32 of this embodiment can also be transmitted in other ways, for example, a pair of bevel gears can be used.
[0046] like Figure 3-Figure 4 as well as Figure 6-Figure 7As shown, the mechanical unlocking module 4 of this embodiment is arranged in the lock body 1, including a lock core 40 and a second transmission mechanism 41. The key socket 401 on the lock core 40 faces the side of the lock body 1, that is, the lock core 40 is arranged horizontally in the lock body 1, which can ensure that the key socket 401 is not provided on the lock panel, and the user cannot see the structure on the front of the lock, which is more aesthetically pleasing. Similarly, the key socket 401 on the side of the lock body 1 can be shielded by setting a side cover 11. When the mechanical emergency key 5 matching the lock core 40 is inserted into the lock core 40, the lock core 40 can be rotated, and the lock core 40 can push the locking member 2 through the second transmission mechanism 41 to switch the locking member 2 to the unlocked position. If it is not a key matching the lock core 40, the lock core 40 cannot be rotated.
[0047] The rotation direction of the lock core 40 is perpendicular to that of the locking member 2, and the second transmission mechanism 41 is used to realize transmission between two mutually perpendicular moving parts. In this embodiment, the second transmission mechanism 41 has a simple structure, and the lock core 40 will not move during electronic unlocking.
[0048] Specifically, the second transmission mechanism 41 of the present embodiment mainly includes: a cam 412, a push block 413, a rotating bracket 411 and a reset spring 410, wherein the rotating bracket 411 is rotatably arranged in the lock body 1, the push block 413 is telescopically arranged in the lock body 1, and a limit groove 101 is provided in the lock body 1, and the push block 413 is telescopically arranged in the limit groove 101 to ensure reliable movement of the push block 413. The cam 412 is fixedly connected to the lock core 40, the push block 413 and the cam 412 are movably opposed to each other, and the cam 412 can drive the push block 413 to telescopically move, thereby rotating the bracket 411, and the rotating bracket 411 pushes the locking member 2, so that the locking member 2 is switched to the unlocked position state.
[0049] The rotating bracket 411 extends a first connecting arm 411A and a second connecting arm 411B to the side of the push block 413 and the side of the locking member 2 respectively. The push block 413 pushes the first connecting arm 411A to rotate the rotating bracket 411. The rotating bracket 411 pushes the locking member 2 through the second connecting arm 411B to switch the locking member 2 to the unlocked position. One end of the reset spring 410 is against the push block 413, and the other end of the reset spring 410 is against the lock body 1. The force of the reset spring 410 on the push block 413 keeps the push block 413 moving toward the cam 412, ensuring that the push block 413 can be quickly reset after the mechanical unlocking is completed. The push block 413 has a boss 413A protruding away from the cam 412. The first connecting arm 411A is provided with a long groove 411C. The boss 413A is movably inserted into the long groove 411C. The boss 413A cooperates with the long groove 411C to prevent the rotating bracket 411 from shifting during the movement process and to prevent movement interference between the push block 413 and the rotating bracket 411.
[0050] During use, when the electronic lock is electronically unlocked: the motor 31 rotates, causing the worm 321 to rotate, the worm 321 drives the worm wheel 322 to rotate, the worm wheel 322 drives the locking member 2 to rotate, the locking member 2 rotates from the locked position to the unlocked position, and the electronic unlocking is achieved, and the lock cylinder 40 remains inactive during this process. When the electronic lock is mechanically unlocked: the mechanical emergency key 5 matching the lock cylinder 40 is inserted into the lock cylinder 40, and drives the lock cylinder 40 to rotate, the lock cylinder 40 drives the cam 412 to rotate, the protrusion of the cam 412 pushes the push member, the push member pushes the first connecting arm 411A of the rotating bracket 411, so that the rotating bracket 411 rotates, the second connecting arm 411B of the rotating bracket 411 pushes the locking member 2, so that the locking member rotates from the locked position to the unlocked position, and the mechanical unlocking is achieved.
