[0017] In order to make the purpose, technical scheme and advantage of the utility model more clear and explicit, the utility model is further illustrated in detail below in combination with specific embodiments and referring to the drawings. It needs to be explained that the embodiment of the utility model and the feature in the embodiment can be combined mutually in the case of not conflicting.

[0018] It is understood that these descriptions are only exemplary, and the scope of the utility model is not limited.

[0019] Some embodiments of the utility model are described below in combination with the drawings to provide a kind of.

[0020] Refer to Figures 1-4The utility model provides a smart door lock which can be switched to a normal open mode, comprising a front handle 1 installed outside a door and a rear handle 2 installed behind the door, the front handle 1 comprises a fixed seat 7 fixed to the door, the front end of the front handle 1 is inserted into the fixed seat 7, at least one through hole 5 is arranged at the fixed seat 7, a ball 6 is installed in the through hole 5, a first gap 8 is arranged on the fixed seat 7 to partially accommodate the ball 6, a switching piece 4 is installed in the front handle 1 and is driven by a driving device 3 to push the ball 6 towards the first gap 8, a switching knob 9 is installed on the rear handle 2 to control the rotation of the switching piece 4, a second gap 10 is arranged on the outer side of the switching piece 4 to partially accommodate the ball 6, when the second gap 10 is aligned with the first gap 8, a cavity is formed to accommodate the ball 6, after the door is closed, the smart door lock cannot automatically switch to a locked state or an unlocked state, and the switching between the locked state and the unlocked state needs to rotate the switching knob 9 to align or misalign the second gap with the first gap, which is more suitable for frequently entering and exiting occasions, and the structure is simpler than that of a conventional smart door lock.

[0021] A sliding cavity 11 is arranged in the front handle 1, the switching piece 4 is slidingly installed in the sliding cavity 11, the switching piece 4 comprises a locking part 12 and an unlocking part 13, the outer diameter of the locking part 12 is adapted to the inner diameter of the sliding cavity 11, the size of the unlocking part 13 is smaller than the inner diameter of the sliding cavity 11, and the second gap 10 is arranged on the outer side of the locking part 12.

[0022] A connecting piece 14 is installed in the switching knob 9 to synchronously rotate, and the end of the connecting piece 14 is fixed to the end of the unlocking part 13.

[0023] When the product is in a normal mode (i.e. the door needs to be unlocked after being closed), the second gap 10 is misaligned with the first gap 8 at this time, when in a locked state, the locking part 12 pushes the ball 6 towards the first gap 8, so that part of the ball 6 is in the first gap 8 and the other part is in the through hole 5, at this time, the ball 6 has a function similar to that of a bolt to fix the front handle 1 to the fixed seat 7, so that the front handle 1 cannot be rotated to open the door, when unlocking, the driving device 3 drives the switching piece 4 to retreat, at this time, the unlocking part 13 is aligned with the first gap 8 to provide sufficient space for accommodating the ball 6, at this time, the ball 6 is entirely below the surface of the through hole 5, and at this time, the front handle 1 can be rotated to open the door.

[0024] When it is needed to switch to the always-on mode, the switching knob 9 is rotated to synchronously rotate the switching piece 4 through the connecting piece 14, at this time, the second notch 10 is aligned with the first notch 8, at this time, no matter whether the driving device 3 drives the switching piece 4 to advance or retreat, the second notch 10 cooperates with the first notch 8, or the first notch 8 cooperates with the unlocking part 13, all can provide sufficient space for accommodating the ball 6, that is, at this time, the front handle 1 can be randomly rotated to open the door.

[0025] In the embodiment, the through holes 5, the first notches 8 and the second notches 10 are all two and symmetrically arranged on both sides of the rotation axis of the front handle 1, so that the strength of locking is improved, and the situation that the front handle 1 is forcibly rotated to easily damage the corresponding locking structure such as the through holes 5 and the first notches 8 is avoided.

[0026] The driving device 3 comprises a shell 15, the shell 15 is internally provided with a telescopic block 17 driven by a motor 16, the telescopic block 17 is fixedly connected with the switching piece 4, and a reset spring for resetting the telescopic block 17 is arranged between the telescopic block 17 and the shell 15; in a normal state, the reset spring pushes out the telescopic block 17, at this time, the locking part 12 is aligned with the first notch 8, that is, after the door is normally closed, the reset spring will push the locking part 12 to advance through the telescopic block 17, so that the ball 6 is pushed to the first notch 8, and the locking effect is achieved.

[0027] The front handle 1 is provided with a decoding disc 18, and the decoding disc 18 is electrically connected with the motor 16 through a control board.

[0028] The same applicant previously applied for a kind of electronic spherical lock's clutch unlocking structure with application number 2023230286197, and the structure principle of the driving device 3 of the present application is same.
