The locking structure 74 of this embodiment adopts screws, and the screws are threaded through the slider 73 and the wireless module 46 of the electric locking assembly 40, and because the wireless module 46 is fixedly installed on the lock body 10, the slider 73 is also fixedly installed on the lock body 10 when the locking structure 74 is installed, and cannot move, and after the locking structure 74 is disassembled, the slider 73 can slide up and down on the slide rail.

The sliding cover 60 of the present embodiment further has a second open position, and a sliding distance along the sliding cover 60 that is greater than the sliding distance of the first open position and less than the sliding distance of the fully open position, that is, the sliding cover 60 slides from top to bottom sequentially through the closed position, the first open position, the second open position, and the fully open position, and accordingly, the unlocking hole 41, the locking structure 74, and the emergency unlocking hole 11 of the wireless module 46 are also arranged from top to bottom. When the sliding cover 60 is located at the closed position and the first open position, the sliding cover 60 covers the locking structure 74, and when the sliding cover 60 is located at the second open position, the sliding cover 60 covers the emergency unlocking hole 11 and avoids the locking structure 74, so that when the sliding cover 60 slides down from the closed position to the first open position after the mechanical locking assembly 30 is unlocked, as shown in fig. 8, the sliding cover 60 avoids the unlocking hole 41 of the wireless module 46, the electric locking assembly 40 can be unlocked, meanwhile, the sliding cover 60 continuously covers the locking structure 74 and the emergency unlocking hole 11, the sliding block 73 cannot slide down continuously, and the emergency unlocking assembly 50 cannot be operated; and after the limiting pin 71 exits the limiting sliding groove 62, the sliding cover 60 can continuously slide downwards to the second opening position, as shown in fig. 9, at this time, the fixed sliding block 73 limits the movement of the sliding cover 60, so that the sliding cover 60 can only move to the second opening position, because the sliding cover 60 at this time avoids the locking structure 74, an operator can operate the locking structure 74 through an external tool to release the locking of the sliding block 73, after the sliding block 73 is unlocked, the sliding block 73 and the sliding cover 60 can continuously slide downwards together, the sliding cover 60 moves to the completely opening position, the emergency unlocking hole 11 is exposed, and thus emergency unlocking can be performed through a corresponding tool.

In this embodiment, the slider assembly 70 further includes a driving pin 75, and the driving pin 75 may be a part of the structure of the slider 73 itself, or may be separately machined and subsequently assembled to the slider 73. The sliding cover 60 is further provided with a transmission sliding groove 63 extending up and down, the transmission pin 75 is connected with the sliding block 73 and is positioned in the transmission sliding groove 63, the length of the transmission sliding groove 63 is larger than that of the limiting sliding groove 62, and therefore the sliding block 73 is matched with the limiting sliding groove 62 to limit the position of the sliding cover 60. Specifically, when the sliding cover 60 moves between the closed position and the second open position, the driving pin 75 is in the driving sliding groove 63, and there is no blocking relationship between the two, so that the sliding cover 60 can move relative to the sliding block 73 at this time, and interference between the movement of the sliding cover 60 and the sliding block 73 is avoided. When the sliding cover 60 moves to the second opening position, as shown in fig. 9, the transmission pin 75 is located at the end of the transmission sliding groove 63, and at this time, when the locking structure 74 is not detached and the sliding block 73 cannot move, the sliding of the sliding cover 60 is blocked and cannot continue to slide down, and after the locking structure 74 is detached, as shown in fig. 10 and 11, the position of the sliding block 73 is no longer locked, the sliding cover 60 can continue to slide down, and the sliding of the sliding cover 60 causes the transmission sliding groove 63 to press the transmission pin 75, so as to drive the sliding block 73 to synchronously slide down. Of course, besides the matching manner of the transmission pin 75 and the transmission sliding groove 63, other matching manners may be adopted to achieve the above-mentioned effects, for example, the slider 73 and the sliding cover 60 are both provided with protruding arms, and when the sliding cover 60 moves to the second opening position, the two protruding arms abut against each other to stop, so as to achieve the control of the position of the sliding cover 60.

The transmission sliding chute 63 of the embodiment is communicated with the sliding closure locking hole 61, and the sliding closure locking hole 61 is larger than the width of the transmission sliding chute 63, so that the structure is simplified, the utilization rate of the sliding closure 60 is improved, the processing is convenient, and the sliding closure 60 cannot move after the mechanical locking component 30 extends into the sliding closure locking hole 61. Of course, the transmission slide 63 and the slide locking hole 61 may be provided independently of each other.

As shown in fig. 1 and 10, in the present embodiment, the sliding cover 60 has an insertion hole 64 for an external tool to extend into, the insertion hole 64 penetrates through the inner side and the outer side of the sliding cover 60, and the insertion hole 64 is communicated with the position-limiting sliding groove 62 and is disposed at the end of the position-limiting sliding groove 62. The receptacle 64 is staggered from the limit pin 71 as the slide cover 60 moves between the closed position and the first open position; when the sliding cover 60 is located at the first open position, the insertion hole 64 is aligned with the limit pin 71, and at this time, an operator can pass an external tool through the insertion hole 64 to push the limit pin 71, and the external tool drives the limit pin 71 to move axially inwards so as to exit from the limit sliding groove 62, and the stop between the external tool and the limit sliding groove 62 is removed. The setting number, the specific position and the like of the limiting pin 71 and the limiting sliding groove 62, the transmission pin 75 and the transmission sliding groove 63 can be adjusted as required, the transmission pin 75 and the transmission sliding groove 63 of the embodiment are provided with a pair and are located on the central line of the sliding cover 60, the limiting pin 71 and the limiting sliding groove 62 are provided with two pairs, and the two pairs are symmetrically arranged at two sides of the sliding cover 60 to ensure stress balance, so that the sliding cover 60 can move smoothly.

In the embodiment, through the mutual cooperation between the components of the sliding block assembly 70 and the sliding cover 60, each sliding of the sliding cover 60 is correspondingly controlled, so that the controllability of the door lock operation is improved, and the door lock is prevented from being operated randomly. Meanwhile, when emergency unlocking is performed, the mechanical locking assembly 30, the limiting pin 71 and the locking structure 74 are required to be sequentially unlocked to perform emergency unlocking operation, so that the emergency unlocking operation is complex in step, illegal personnel can be prevented from cracking, and meanwhile, the emergency unlocking hole 11 is hidden, so that the safety of the door lock is improved. Of course, the setting manner, the operation steps, and the like can be adjusted by deletion and the like according to needs, for example, the slider 73 and the second opening position are not provided, and the slide cover 60 can directly move to the fully opening position when sliding through the first opening position; other matching methods are adopted between the sliding block 73 and the sliding cover 60.

As shown in fig. 1 to 5 and 12 to 14, in the present embodiment, the mechanical locking assembly 30 includes a lock cylinder 31 and a mechanical locking shaft 32, the lock cylinder 31 is disposed on the lock body 10, the lock cylinder 31 has an unlocking insertion opening exposed out of the lock body 10, and a mechanical key is inserted into the unlocking insertion opening to unlock the lock cylinder 31.

After the initial state is set, the subsequent unlocking operation can be completed only by a mechanical unlocking key, and the electric locking assembly 40 does not play a role.

The mechanical unlocking operation process is opposite to the mechanical locking operation process, and is not described in detail.

3. Electric locking mode

Setting an initial state:

different from the double locking mode, when the double locking mode is switched to the electric locking mode, after the double unlocking process of the electric unlocking and the mechanical unlocking, the mechanical locking operation is not carried out any more, and only the electric locking operation is carried out.

Electric locking operation:

the operator first slides the latch 20 from the unlatched position to the latched position; at this point, the power latch slot 22 of the latch member 20 is aligned with the power latch shaft 44;

then, the operator inserts the electronic key into the unlocking hole 41, the electronic key supplies power to the wireless module 46, after the door lock identity authentication is passed, the electronic circuit 80 controls the driving part 42 to rotate in the reverse direction, and the driving part 42 rotates in the reverse direction to synchronously drive the transfer shaft 43 to rotate in the reverse direction; the convex column 431 of the transfer shaft 43 presses the side wall of the driving groove 441 to drive the electric locking shaft 44 to slide, and one end of the electric locking shaft 44 extends into the electric locking groove 22 under the action of the elastic force of the electric resetting piece 45, so that the locking piece 20 is locked, and the electric unlocking state is switched to the electric locking state;

the slider 60 is then slid from the first open position to the closed position.

After the initial state is set, the subsequent unlocking operation can be completed only by the electronic key, and the mechanical locking assembly 30 does not function.

The electric unlocking operation process is opposite to the electric locking operation process, and is not described again.

4. Emergency unlocking process:

the operator inserts the mechanical unlocking key into the unlocking insertion opening of the key cylinder 31 and rotates the key cylinder 31.

if the door lock setting state is the electric locking mode, the initial state of the slide cover 60 is the unlocking state, and the two operation steps can be omitted.

Then, the operator slides the slide cover 60, the stopper pin 71 is not moved, and the stopper pin 71 moves from one end of the stopper slide groove 62 to the other end with respect to the slide cover 60, so that the slide cover 60 is switched from the closed position to the first open position, and the slide cover 60 is exposed from the unlocking hole 41. At this time, the insertion hole 64 on the end of the limit chute 62 is aligned with the limit pin 71; the driving pin 75 is stationary, and the driving pin 75 continues to move in the driving sliding groove 63 relative to the sliding cover 60;

an operator pushes the limit pin 71 to overcome the elastic force of the limit reset piece 72 through an external tool such as a fine needle and the like through the jack 64, so that the limit pin 71 moves to exit the limit sliding groove 62, and the limit effect of the limit pin 71 on the sliding cover 60 is relieved;

the operator continues to slide the sliding cover 60, the transmission pin 75 is not moved, and the transmission pin 75 continues to move to the other end in the transmission chute 63 relative to the sliding cover 60, at this time, the sliding cover 60 exposes the operation positions of the unlocking hole 41 and the locking structure 74, and covers the emergency unlocking hole 11, and at this time, the sliding cover 60 is in the second opening position;

The operator continues to slide the sliding cover 60, the sliding cover 60 abuts against the end of the transmission sliding groove 63 through the transmission pin 75 to drive the sliding cover 60 to move to the other end, at this time, the sliding cover 60 sequentially exposes the unlocking hole 41, the operation position of the locking structure 74 and the emergency unlocking hole 11, and the sliding cover 60 is in the fully opened position.

An operator inserts an emergency unlocking key into the emergency unlocking hole 11 and cooperates with the emergency unlocking shaft 51 to drive the emergency unlocking shaft 51 to rotate; the emergency unlocking boss 512 of the emergency unlocking shaft 51 presses the side wall of the emergency unlocking groove 442 to drive the electric locking shaft 44 to slide, and one end of the electric locking shaft 44 exits the electric locking groove 22, thereby unlocking the locking member 20;

at this time, the operator may pull out the latch member 20, and the door lock is switched from the latched state to the unlatched state.

The lock has two kinds of emergency unlocking modes of difference, only need default or assemble backstop round pin 52 and backstop reset piece 53 when the equipment can accomplish the switching of different emergency unlocking modes, no matter which kind of emergency unlocking mode, the emergency unlocking process is above-mentioned process, and the difference of the two lies in once the follow-up after the emergency unlocking is accomplished:

in the single emergency unlock mode, initial setting of the door lock is completed by fitting the stop pin 52 during assembly. When one-time emergency unlocking is completed, namely the emergency unlocking shaft 51 rotates to the position where the stop groove 511 is aligned with the stop pin 52 along the circumferential direction, the stop pin 52 extends into the stop groove 511 under the elastic force of the stop reset piece 53 to limit the rotation of the emergency unlocking shaft 51; at this time, the panic unlocking shaft 51 cannot move any further, and the electric lock shaft 44 always remains withdrawn from the electric lock groove 22, so that the panic unlocking function is disabled.

In the infinite emergency unlocking mode, the initial state setting can be completed without assembling the stopper pin 52 and the stopper returning member 53 when the door lock is assembled. Since there is no stopper pin 52 stopping the movement of the emergency unlocking shaft 51, the emergency unlocking key can be used repeatedly.

In the above embodiments, a plurality means at least two, and the top, bottom, and lateral and longitudinal directions in the above embodiments are directions in fig. 1.
