The motor 71 is located at the original position, namely the position of the motor 71 before the intelligent door lock is locked, after the intelligent door lock is locked, the intelligent door lock can be unlocked through reverse rotation of the motor 71, mechanical unlocking can also be performed through a key, a user can drive the locking shifting block 74 to rotate through the key shifting piece when rotating the key, and then the locking shifting block 74 acts on the main bolt 2 to enable the main bolt to retract into the shell 1. After locking, when the motor 71 rotates reversely to the original position, the user does not need to overcome the resistance of the motor 71 when unlocking mechanically through the key, and the mechanical unlocking is convenient to carry out.

Specifically, during locking, when the controller controls the motor 71 to drive the driving gear 72 to rotate in the forward direction, the eccentric protrusion 721 of the driving gear 72 rotates to abut against the upper locking shifting block 74 and then can push the upper locking shifting block 74 to rotate around the axis of the driving gear 72, and when the upper locking shifting block 74 rotates to push the main bolt 2 to move to the first trigger 22 to trigger the upper locking switch 62, the main bolt 2 is in the pop-up state, the intelligent door lock is locked, the upper locking switch 62 can send a locking signal to the controller, the controller controls the motor 71 to drive the driving gear 72 to rotate in the reverse direction according to the locking signal and drives the eccentric protrusion 721 to rotate in the reverse direction to disengage from the upper locking shifting block 74, at this time, the position of the upper locking shifting block 74 is not moved, the main bolt 2 is still in the pop-up state, when the motor 71 rotates to the second trigger 731 to trigger the reset switch 63, the, when the motor 71 is rotated to the original position, the controller controls the motor 71 to stop driving according to the reset signal, at this time, the door lock is still in a locked state, and at this time, if the door lock is mechanically unlocked by the key, the rotation of the key can drive the locking shifting block 74 to rotate reversely through the key shifting piece so as to enable the main bolt 2 to move reversely into the housing 1 to realize unlocking, and in the process, the motor 71, the driving gear 72 and the driven gear 73 do not need to rotate, so that the mechanical unlocking operation is facilitated.

In the lock body provided by the embodiment, the locking is realized through the locking switch 62 and the first trigger piece 22 of the main bolt 2, then the locking signal is sent to the controller to enable the controller to control the motor 71 to stop rotating, and meanwhile, the reset switch 63 and the second trigger piece 731 arranged on the driven gear 73 realize that the motor 71 resets and then the reset signal is sent to the controller to enable the controller to control the motor 71 to stop driving. The main bolt 2 is located to first trigger piece 22, driven gear 73 is located to second trigger piece 731, only through two gears of driving gear 72 and driven gear 73, can need not to overcome the resistance of motor 71 when guaranteeing that the user passes through key machinery unblock, need not to set up other limit structure, and then can simplify overall structure, the economic nature is good and the installation of being convenient for, and driving gear 72 and driven gear 73 meshing's mode realizes the transmission, stability is good and control accuracy is high, avoid the position of second trigger piece 731 to take place the skew and influence motor 71 and reset.

Specifically, the main bolt 2 may directly trigger the locking switch 62 through the trigger when being ejected, or the first trigger 22 may trigger the locking switch 62 through the adaptor 221, which is not limited herein and may be set according to a specific structural arrangement.

In this embodiment, for the main lock tongue 2, the scissor tongue 3 and the detection tongue 4, the inner end refers to the end located in the housing 1, and no matter whether the inner end is in the pop-up state, the inner end is located in the housing 1, and the outer end corresponding to the inner end in the pop-up state can extend out of the housing 1. If the inner end of the scissor tongue 3 is provided with the locking groove 31, if the scissor tongue 3 is in an ejected state, the locking block 51 can move to be matched with the locking groove 31 under the action of the locking spring 52 and trigger the locking switch 61, if the door is in a virtual state, the scissor tongue 3 is pressed and positioned in the shell 1, the locking block 51 moves to be abutted against the end face of the locking groove 31 under the action of the locking spring 52, and at the moment, the end face of the locking groove 31 limits the movement of the locking block 51, so that the locking block 51 cannot trigger the locking switch 61; the inner end of the main bolt 2 is provided with an upper lock groove 21, and an upper lock shifting block 74 can rotate around the rotation axis of the driving gear 72 and can abut against the groove wall of the upper lock groove 21 when rotating so as to push the main bolt 2 to pop out to be locked.
