[0048] Embodiment 1:

[0049] like Figure 1-Figure 4 Combined with Figure 7 As shown, a mechanical unlocking module of an electronic lock is configured in the lock body 4 of the electronic lock, and can switch the locking member 5 in the electronic lock from a locked state to an unlocked state. When the locking member 5 is in the locked state, the electronic lock cannot be unlocked, and the electronic lock can only be unlocked by switching the locking member 5 to the unlocked state. The locking member 5 can be rotatably switched between the unlocked state and the locked state. The locking member 5 has a locking block. When the locking member 5 is in the locked state, the locking block protrudes outward from the lock body 4 and cooperates with other locking structures; when the locking member 5 is switched to the unlocked state, the locking block rotates into the lock body 4.

[0050] The mechanical unlocking module of this embodiment mainly includes: a lock core 1 , a rotating frame 2 , and a transmission mechanism 3 arranged between the lock core 1 and the rotating frame 2 . The transmission mechanism 3 mainly includes a push plate 31 and a push bracket 32 ​​.

[0051] The lock cylinder 1 is rotatably mounted in the lock body 4, and the lock body 4 has a key socket 40, which is located on the side of the lock body 4, rather than the front, to improve the aesthetics of the lock. The lock cylinder 1 has a matching mechanical emergency key 7, and when the mechanical emergency key 7 matching the lock cylinder 1 is inserted into the lock cylinder 1 along the key socket 40, the mechanical emergency key 7 can drive the lock cylinder 1 to rotate. The mechanical emergency key 7 can be used as a management key to unlock the lock in an emergency during after-sales service.

[0052] The rotating frame 2 is rotatably arranged in the lock body 4, and can drive the locking member 5 to switch to the unlocking state. The rotating direction of the rotating frame 2 is perpendicular to the rotating direction of the lock core 1. In the mechanical unlocking process of this embodiment, the rotating direction of the lock core 1 is perpendicular to the rotating direction of the locking member 5. The transmission mechanism 3 and the rotating bracket realize the output of the motion in the vertical direction. It has a wide range of applications and ensures that the lock core 1 is arranged horizontally. The key socket 40 can be arranged on the side of the lock body 4, which is aesthetically pleasing.

[0053] The transmission mechanism 3 is arranged between the rotating frame 2 and the lock core 1, and is connected to the lock core 1. The transmission mechanism 3 includes a push plate 31 and a push bracket 32, and an end cover 10 is provided at the end of the lock core 1. The push plate 31 is rotatably connected to the end cover 10 at the end of the lock core 1, and the push bracket 32 ​​is movably connected to the push plate 31 and is movably connected to the rotating frame 2. It should be explained that the push bracket 32 ​​and the push plate 31 are movably connected in the following manner: a sliding shaft 321 is provided on the push bracket 32, and an arc groove 310 is provided on the push plate 31, and the sliding shaft 321 is slidably penetrated in the arc groove 310. When the push plate 31 rotates and the relative position of the sliding shaft 321 in the arc groove 310 changes, the push plate 31 will not drive the push bracket 32. Only when the sliding shaft 321 reaches the end of the arc groove 310 and the push plate 31 continues to rotate, the push plate 31 will push the push bracket 32, thereby driving the push bracket 32 ​​to drive the rotating frame 2.

[0054] Among them, one end of the rotating frame 2 is provided with a waist hole 20, and the push bracket 32 ​​protrudes a boss 320 to the side thereof. The boss 320 is movably inserted into the waist hole 20, and the boss 320 can push the side wall of the waist hole 20, so that the end of the rotating frame 2 away from the waist hole 20 pushes the locking member 5. The boss 320 and the waist hole 20 are movably matched to avoid the jamming between the push bracket 32 ​​and the rotating frame 2 during the mechanical unlocking process, and it can also ensure that the push bracket 32 ​​can push the rotating frame 2, so that the rotating frame 2 rotates, and the locking member 5 rotates and switches to the unlocking state. A limit pin 311 is provided on the push plate 31, and the lock core 1 can push the limit plate, so that the limit pin 311 is pressed against the lock body 4 and slides along the lock body 4, and the push plate 31 drives the push bracket 32, and the limit pin 311 can limit the movement of the push plate 31.

[0055] When the mechanical emergency key 7 matching the lock cylinder 1 is inserted into the lock cylinder 1 and the lock cylinder 1 is rotated, the lock cylinder 1 drives the push plate 31. At the initial stage of movement, the push plate 31 moves to change the relative position of the sliding shaft 321 on the push bracket 32 ​​in the arc groove 310, and the push bracket 32 ​​does not move until the sliding shaft 321 is at the end of the arc groove 310. The push plate 31 continues to move and pushes the sliding shaft 321, causing the push bracket 32 ​​to move. As the boss 320 on the push bracket 32 ​​moves to the side of the waist hole 20 on the rotating frame 2, the push bracket 32 ​​pushes the rotating frame 2 through the boss 320, causing the rotating frame 2 to rotate in the direction close to the locking member 5, forcing the locking member 5 to rotate to the unlocked state.

[0056] In this embodiment, the mechanical unlocking module of the electronic lock includes a lock core 1, a rotating bracket and a transmission mechanism 3. When the electronic lock needs to be unlocked in an emergency, a mechanical emergency key 7 matching the lock core 1 is inserted into the lock core 1 to rotate the lock core 1. The lock core 1 drives the rotating bracket 2 to rotate through the transmission mechanism 3, thereby rotating the locking member 5 from a locked state to an unlocked state, thereby unlocking the locking member 5. The overall structure of the mechanical unlocking module is simple.

[0060] The electronic unlocking module 6 is arranged in the lock body 4, and can drive the locking member 5 to rotate, so that the locking member 5 can rotate and switch between the locked state and the unlocked state. Specifically, the electronic unlocking module 6 of this embodiment includes a battery 60, a motor 61, a worm 62 and a worm wheel 63. The lock body 4 extends a lock shaft 41 vertically outward, and the motor 61 is installed in the lock shaft 41. This arrangement can free up the main installation space of the lock body 4 for installing other modules, so that the structure of the electronic lock is more compact and more conducive to the miniaturization of the electronic lock. The worm 62 is arranged on the output shaft of the motor 61, and the worm wheel 63 is connected to the locking member 5 and drives with the worm 62. A circuit board is arranged in the lock body 4, and the circuit board can control the operation of the motor 61. A battery compartment 11 is arranged on the lock body 4, and the battery compartment 11 can be quickly disassembled on the lock body 4, so as to facilitate the replacement of the battery 60.

[0061] During use, when the electronic lock is unlocked electronically, the motor 61 rotates, causing the worm 62 to rotate, the worm 62 drives the worm wheel 63 to rotate, and the worm wheel 63 drives the locking member 5 to rotate, so that the locking member 5 rotates from the locked state to the unlocked state. When the electronic lock is unlocked by the mechanical emergency key 7, the specific unlocking process is described in detail in the first embodiment, which will not be repeated here.

[0062] Preferably, a threaded sleeve 8 is sleeved on the lock shaft 41, and the threaded sleeve 8 is detachably connected to the lock body 4, and an external thread is arranged on the outer wall of the threaded sleeve 8 along its own circumference.
