When the motor 13-6 acts, the shifting sleeve 13-9 is driven to rotate, and when the shifting sleeve 13-9 rotates, the locking plate 13-5 is pushed to move through the eccentric shaft 13-9a, so that the locking plate is separated from the locking bolt 13-3. The motor 13-6 is electrically connected to the controller 3 (fig. 9), and the operation of the motor 13-6 is controlled by the controller 3. The controller 3 may be integrated into the lock body 1 or may be independent from the lock body 1. The controller 3 of this embodiment is external, and the controller 3 may be powered by a rechargeable battery, or powered from other devices in the cabinet or connected to commercial power. Further, the dial sleeve 13-9 of the present embodiment is of a cam structure, and a first microswitch 13-10 is disposed in the unlocking module 13. The first microswitch 13-10 of the embodiment is arranged on the outer wall (rear cover plate) of the locking plate sliding groove 13-2 b. The first microswitch 13-10 is used as a motor action inductor and has the function of collecting the rotation state of the dial sleeve 13-9 (a motor output shaft). The first micro switches 13-10 are connected to the controller 3 so as to transmit the rotation information of the dial sleeve to the controller 3. When the motor 13-6 drives the dial sleeve 13-9 to rotate for one circle, the state of the first microswitch 13-10 is changed, and the state of the first microswitch 13-10 is changed from closed state to open state, the dial sleeve 13-9 rotates for one circle, namely the eccentric column 13-9a returns to the initial position after being unlocked. The controller 3 controls the motor to rotate for one circle each time when the motor is unlocked by acquiring the state change of the first microswitch 13-10.
A locking plate reset spring 13-7 is arranged between the locking plate 13-5 and the locking plate sliding groove 13-2a (the rear cover plate 13-2), and the locking plate reset spring 13-7 provides a force for the locking plate 13-5 to move to the position which is abutted against the limiting part 13-3a on the lock bolt 13-3. In the embodiment, the locking plate 13-5 is provided with a spring groove for accommodating the locking plate return spring 13-7, the locking plate return spring 13-7 is arranged in the spring groove, one end of the locking plate return spring abuts against the inner wall of the spring groove, and the other end of the locking plate return spring abuts against the locking plate sliding groove 13-2 a.
The locking plate 13-5 is also connected with the lock cylinder linkage plate 13-8. The lock core linkage plate 13-8a is provided with an assembly hole 13-8a (figure 4), the lock core 12 is connected with the lock core linkage plate 13-8 through the matching between an eccentric column 12a arranged on the rear end part of the lock core and the assembly hole 13-8a, and the eccentric column 12a extends into the assembly hole 13-8a on the lock core pull rod 13-8. After the lock cylinder 12 is unlocked, the lock cylinder 12 is operated to rotate through a key, and the lock cylinder linkage plate 13-8 further drives the lock plate 13-5 to rotate, so that unlocking is realized.
As shown in FIG. 7, in the normal locking state, the upper part of the lock bolt 13-3 passes through the locking ring 2, and one end of the locking plate 13-5 extends into the limiting part 13-3a of the lock bolt 13-3, so as to clamp the lock bolt 13-3, so that the lock bolt cannot move downwards, and the cabinet door cannot be opened. As shown in figure 8, when unlocking, the locking piece 13-5 exits the limiting part 13-3a of the locking bolt 13-3, the locking bolt 13-3 is separated from the limiting part of the locking piece 13-5, and the locking bolt 13-3 is moved downwards under the action of the locking bolt spring 13-4 to be separated from the locking ring 2, so that the cabinet door can be opened.
Further, the unlocking module 13 further includes a second micro switch 13-11 (fig. 7), and the second micro switch 13-11 is disposed at an end of the latch 13-3 for sensing a position of the latch 13-3, so that a state of the door lock (i.e., a lock state detecting means) can be detected. The second microswitch 13-11 is connected to the controller 3 so as to send the position information of the latch 13-3 to the controller 3. In order to avoid the latch 13-3 from frequently contacting with the second microswitch 13-11 and causing the second microswitch 13-11 to be damaged, preferably, an elastic sheet 13-12 is arranged between the latch 13-3 and the second microswitch 13-11, and the end part of the latch 13-3 contacts with the second microswitch 13-11 through the elastic sheet 13-12. The impact on the first microswitch 13-10 is smaller than that on the second microswitch 13-11, and a protective elastic sheet is not needed. The motor action sensor (13-10) and the lock bolt position sensor (13-11) can adopt sensors such as a Hall device, a proximity sensor and the like besides a microswitch.
As shown in fig. 9, the controller 3 is connected to the remote lock control system host 4 through the wireless communication module, and performs information interaction with the lock control system host 4 through the wireless network, so as to send the state of the lock plunger sensed by the second micro switch to the lock control system host 4, so that the remote management center can obtain the state of the door lock in time. The lock control system host 4 is a conventional remote management platform, and the lock control system host 4 is preset with general microcomputer anti-misoperation system software in the prior art and is used for management, authorization and other operations of locks. The lock control system host 4 can send an instruction to the controller 3 to unlock the door lock. More preferably, in order to reduce the power consumption of the system, the cabinet door lock further includes a wake-up button 5, the wake-up button 5 is disposed on the outer shell 11, and the wake-up button 5 is electrically connected to the controller 3. In a normal state, the controller 3 is in a dormant state, when unlocking is needed, the awakening button 5 is pressed down first, the controller 3 is awakened from the dormant state, then the lock control system host 4 can send an unlocking signal to the controller 3, the controller 3 controls the motors 13-6 to act according to the unlocking signal sent by the lock control system host 4, and unlocking is carried out, and in the unlocking process, the rotation state of the motors sensed by the first micro switch can be convenient for controlling the rotation stroke of the motors; the second micro-switches 13-11 collect the state of the door lock (lock bolt) and send the collected information to the controller 3, and the controller 3 uploads the current state information of the door lock to the lock control system host 4. When the door lock is in the awakening state, the lock control system host 4 can request the controller 3 to upload the current state of the door lock at any time. The wake-up button 5 is arranged to further have an effect of confirming that the operator is in place, for example, the controller 3 is in a dormant state in a normal state, the controller 3 cannot receive an unlocking signal to unlock in the dormant state, the unlocking signal can be sent to the controller 3 to unlock only after the operator presses the wake-up button 5 to wake-up the controller 3 on site, and the unlocking signal cannot be sent to the controller to unlock if the operator is not in place. In addition, in order to enable the lock control system host 4 to periodically check the status of the cabinet door lock, the controller 3 may be configured to periodically and automatically wake up (i.e., may automatically wake up without pressing a wake-up button), and the current status of the cabinet door lock is actively uploaded to the lock control system 4 after the controller 3 automatically wakes up. The period of automatic wake-up may be 24 hours or 12 hours or 8 hours, or other times.
As shown in fig. 11, the lock control system includes an electric control lock (cabinet door lock), a controller 3, and a lock control system host 4, and the lock control system host 4 is connected to the controller 3 in a remote communication manner. The electric control lock is internally provided with a driving unit (a motor), a lock state detection device (a second microswitch) and a driving unit action inductor (a first microswitch) which are electrically connected with the controller 3.
The door lock of the invention has two unlocking channels: the motor unlocking channel and the lock cylinder unlocking channel. These two unlocking methods will be described below with reference to fig. 7 and 8.
Unlocking a channel by the motor: as shown in fig. 7, when locking, the locking plate 13-5 extends into the limiting part 13-3a of the locking bolt 13-3, the locking bolt 13-3 cannot move, and the upper part of the locking bolt passes through the locking ring 2 to realize locking; when the controller is in an awakening state, when the lock control system host 4 sends an unlocking signal to the controller 3 through a network, after the controller 3 receives the unlocking signal, the motor 13-6 is controlled to rotate, the motor 13-6 drives the dial sleeve 13-9 to rotate for a circle, the eccentric shaft 13-9a at the end part of the dial sleeve 13-9 drives the lock plate 13-5 to move, the lock plate 13-5 leaves the limiting part 13-3a of the lock bolt 13-3, and after the lock bolt 13-3 leaves the limiting part of the lock plate 13-5, the lock bolt moves downwards under the action of the lock bolt spring 13-4 to separate from the lock ring 2, so that unlocking is realized (figure 8). In the unlocking process, the controller 3 collects the rotation information of the motor through the first micro switches 13-10, so that the motor is controlled to rotate for one circle each time the motor is unlocked. When locking, the lock bolt 13-3 is pushed upwards, the upper part of the lock bolt passes through the lock ring 2, and the lock plate 13-5 extends into the limiting part 13-3a of the lock bolt 13-3 again under the action of the lock plate return spring 13-7 to limit the lock bolt 13-3, so that locking is realized.
In addition, the unlocking signal can be sent to the controller 3 through the mobile terminal 6 to perform unlocking operation. As shown in fig. 10, the mobile terminal 6 obtains an unlocking authorization from the lock control system host 4, and sends an unlocking signal to the controller 3 through bluetooth, and the controller 3 controls the motor 13-6 to act for unlocking. The door lock state information collected by the second micro switches 13-11 can be directly sent to the lock control system host 4 through the controller 3, and under the condition of bad network, the door lock state information can also be sent to the mobile terminal 6 through the controller 3, and then sent to the lock control system host 4 through the mobile terminal 6.
