In this embodiment, the driving member 62 is rotatably disposed on the panel 10; the clearance structure comprises a first abutting part 32 arranged on the free piece 30 and a second abutting part 63 arranged on the driving piece 62, and when the free piece 30 is in a first initial state and the driving piece 62 is in a second initial state, the first abutting part 32 and the second abutting part 63 are separated by a distance; the driving motor 61 can drive the driving member 62 to rotate, so that the second abutting portion 63 abuts against the first abutting portion 32, and the driving member 62 can drive the release member 30 to rotate. In use, when the handle 20 is used to rotate the switch lock, the first abutting portion 32 of the free piece 30 rotates within the interval range between the first abutting portion 32 and the second abutting portion 63, so that the driving piece 62 is not driven to rotate, when the driving motor 61 is used to automatically switch the lock, the driving piece 62 can rotate until the first abutting portion 32 abuts against the second abutting portion 63, and then the free piece 30 can be driven to rotate after continuing to rotate, so that the switch lock is realized.

In this embodiment, the number of the second abutting portions 63 is two and are respectively disposed on two opposite sides of the first abutting portion 32, so that the driving member 62 is not driven to rotate by the forward rotation and the reverse rotation of the handle 20, and the handle 20 can switch the operations such as the switch lock and the reverse lock through the switching of the rotation direction thereof. In other embodiments, the number of the first contact portions 32 may be two and provided on opposite sides of the second contact portion 63, so that the above-described effects can be obtained.

In other embodiments, the rotation angle of the free member 30 from the initial state to the operation state can be flexibly adjusted as required.

In the present embodiment, the driving motor 61 drives the driving piece 62 to rotate through the gear transmission mechanism 66, and meanwhile, the gear connected to the output shaft of the driving motor 61 is a bevel gear, so that the driving motor 61 can be arranged parallel to the panel 10, which contributes to reducing the thickness of the door lock. In other embodiments, the driving motor 61 may alternatively use a belt transmission mechanism, a rack transmission mechanism, or other suitable transmission structures to drive the driving member 62 to move, which is not limited thereto.

The panel 10 is provided with a detector 71 for detecting whether the driving member 62 is in the second initial state, so that the driving member 62 can be reset by automatically controlling the driving motor 61 in use in cooperation with a control device such as a circuit board on a door lock, and the normal operation of the door lock is ensured to be more reliable. In this embodiment, the detector 71 adopts a contact switch, and meanwhile, the driving member 62 is convexly provided with a detection block, and the detection block can trigger the contact switch along with the rotation of the driving member 62, so that the structure is simple and reliable, the cost is low, and the processing, the assembly and the control are convenient. In other embodiments, the detector 71 may also employ other commonly used detecting structures such as an infrared sensor, a hall sensor, etc., but is not limited thereto.

In this embodiment, a first torsion spring 72 is disposed between the handle 20 and the panel 10, and is used for driving the handle 20 to rotate and reset. In addition, the free piece 30, the driving piece 62, the driving motor 61 and the transmission mechanism thereof are all installed in a box body 11 to form a modularized structure, meanwhile, a rotatable connecting piece 23 is additionally arranged in the box body 11, the connecting piece 23 protrudes out of the box body 11, and the connecting piece 23 can be regarded as a part of the handle 20 in the utility model and is used for being connected with the holding part of the handle 20, so that the processing and the assembly are convenient, the production cost is reduced, and the production efficiency is improved.

In addition, a second torsion spring 73 is disposed between the free member 30 and the panel 10, and is used for driving the free member 30 to rotate and reset to the first initial state, so that on one hand, the free member 30 can be driven to rotate and reset without the aid of the driving motor 61, which is helpful for extending the endurance, and on the other hand, when the driving motor 61 fails or is damaged, the second torsion spring 73 can also reset and maintain the free member 30 to the first initial state, which is helpful for improving the anti-theft performance of the door lock.
