When the pin 17 extends into the locking groove 18, the electronic locking mechanism is in a locked state, and when the pin 17 exits from the locking groove 18, the electronic locking mechanism is in an unlocked state.

The lock core 1 is of a three-section structure and is divided into a front section lock core, a middle section lock core and a rear section lock core which are connected, a locking side column locking mechanism 8 is located in the front section lock core, a locking groove 18 is formed in the rear section lock core, a lock core transmission part is arranged in the middle section lock core, the lock core transmission part shown in the figure is a shifting peach 19, when the lock core 1 is unlocked and rotates, a lock tongue can be driven by the shifting peach 19 and the transmission mechanism to act, an unlocking function is achieved, in order to facilitate shifting peach 19 rotation, a rectangular notch 20 is formed in a lock core hole part and a convex side part of the lock sleeve 2, after the front section lock core is installed in the lock core hole 3, the left side of the notch 20 is located through a clamp spring, after the rear section lock core is installed in the lock core hole, the right side of the notch 20 is located through another clamp spring, and two ends of the middle section lock core are respectively connected with the front section lock core and the rear section lock core in a clamping mode, and are clamped and fixed by the front section lock core and the rear section lock core.

Of course, the lock cylinder transmission member may have a different form, such as a gear or the like, in addition to the dial 19.

The lock sleeve 2 is provided with a lock core PCB mounting groove at the top of the protruding side edge part 4, the lock core PCB 12 is fixed on the lock sleeve 2 through screws, a travel switch 13 and an electromagnet 14 are respectively arranged on the lower surface of the lock core PCB 12, a connector 15 is arranged on the upper surface of the lock core PCB 12, and the side edge part 4 of the lock sleeve 2 is provided with a groove position and a hole position for accommodating the travel switch 13, the electromagnet 14 and a marble component 16.

The marble component 16 is used for triggering the travel switch 13 and reading chip information of the key 7, and simultaneously realizes two functions, and is electrically connected with the lock cylinder PCB 12 of the electronic locking mechanism.

The lock cylinder 1 and the lock sleeve 2 are provided with corresponding marble holes at the front side of the locking side column locking mechanism 8, a primary insulating sleeve 21 and a primary conductive marble 22 are arranged in the marble holes of the lock cylinder 1, a secondary insulating sleeve 23 and a secondary conductive marble 24 are arranged in the marble holes of the lock sleeve 2, the primary conductive marble 22 and the secondary conductive marble 24 are electrically connected with the lock cylinder PCB 12, the secondary conductive marble 24 is linked with the travel switch 13, and the travel switch 13 can be triggered, wherein the secondary conductive marble 24 can be electrically connected with the lock cylinder PCB 12 all the time or can be electrically connected with the lock cylinder PCB 12 after moving.

The travel switch 13 is located on the right side of the secondary conductive marble 24, the secondary conductive marble 24 is provided with a transverse notch 25 for triggering the travel switch 13, and a triggering arm 26 of the travel switch 13 extends into the notch 25 of the secondary conductive marble 24 from the side and is supported on the bottom surface of the notch 25. Thus, when the primary conductive marble 22 supports the secondary conductive marble 24 to move upwards, the trigger arm 26 of the travel switch 13 is driven to swing upwards, so as to trigger the travel switch 13.

The tail of the secondary conductive marble 24 is provided with a spring mounting hole, the secondary conductive marble is supported on the lock cylinder PCB 12 through a conductive spring 27, the lock cylinder PCB 12 is provided with a bonding pad at a position corresponding to the conductive spring, and the conductive spring 27 is always contacted with the bonding pad. When the key 7 is inserted, the chip signal on the key 7 is conducted with the lock core PCB 12 through the first conductive ball 22, the second conductive ball 24 and the conductive spring 27.

The above structure is only one specific way for the two-stage conductive marble 24 to realize the triggering and reading functions simultaneously, and on the basis, various other linkage ways of the two-stage conductive marble 24 and the travel switch 13 can be designed.

For example, in another embodiment, the travel switch 13 may be located above the second conductive marble 24, where the tail of the second conductive marble 24 is used as a trigger portion to trigger the travel switch 13, and meanwhile, in order to achieve conduction between the second conductive marble 24 and the lock cylinder PCB 12, the second conductive marble 24 may be electrically connected to the lock cylinder PCB 12 through a wire or a conductive elastic sheet, and the rest of the structure is substantially the same as that of the first embodiment described above.

Alternatively, in yet another embodiment, the travel switch 13 is located on one side of the secondary conductive marble 24, but the secondary conductive marble 24 is not provided with a notch 25, but is provided with a lateral boss or lug, and when it moves upward, the travel switch 13 is triggered by the lateral boss or lug, and the rest of the structure is substantially the same as the first embodiment described above.

Alternatively, in other embodiments, the secondary conductive marble 24 may be drivingly connected to the travel switch 13 through other types of transmission members, so as to trigger the travel switch 13 when it moves upward, and the rest of the structure is substantially the same as that of the first embodiment described above.

It can be seen that the two-stage conductive marble 24 and the travel switch 13 can be directly connected in a transmission manner by contact, abutting, hinging and the like, or indirectly connected in a transmission manner by a transmission component such as a connecting rod and the like, and the two components are not necessarily connected into a whole or are not detachable.

Because the electronic locking mechanism can realize the triggering and reading functions only by arranging a group of marble assemblies 16, the switch marble assemblies and the password reading marble assemblies are not required to be arranged separately, so that the structure of the lock cylinder is simplified, the length of the lock cylinder is shortened, the electronic locking mechanism can be arranged on a door with thinner thickness, and the types of compatible doors are more, so that the application range of the lock cylinder is wider.

Referring to fig. 3 and 4, fig. 3 is a schematic view illustrating an internal structure of the mechatronic lock shown in fig. 1 in a state in which a small portion of a key is inserted; fig. 4 is a schematic view showing an internal structure of the mechatronic lock shown in fig. 1 in a state in which a key is fully inserted.

As shown, when the travel switch 13 is not triggered, the pin 17 exits the locking slot 18 in the unlocked position; when the travel switch 13 is triggered and electronic verification is not performed, the pin shaft 17 enters the locking groove 18 to be in a locking position; when the travel switch 13 is triggered and the electronic verification is qualified, the pin shaft 17 exits the locking groove 18 and is positioned at the unlocking position; when the travel switch 13 is triggered and the electronic verification is failed, the pin 17 is kept in a state of entering the locking groove 18, and is in a locking position.

The working principle is as follows:

when the key 7 is not inserted into the lock cylinder 1, the pin shaft 17 of the electromagnet 14 is retracted, and the design can ensure the mechanical unlocking function of the key 7 when the panel is not powered.

When the key 7 is inserted into the lock cylinder 1, the front end of the key 7 is contacted with the primary conductive marble 22, and then the travel switch 13 is triggered by the secondary conductive marble 24, the panel powers on the lock cylinder PCB 12, the chip on the lock cylinder PCB 12 controls the pin shaft 17 of the electromagnet 14 to extend out, and the pin shaft is inserted into the locking groove 18 of the lock cylinder 1. When the lock cylinder 1 is illegally opened, the safety of the lock cylinder 1 can be ensured.

When the key 1 is further inserted until the contact 31 on the key is contacted with the primary conductive marble 22, the PCB on the key 7 forms a conducting circuit with the lock cylinder PCB 12 through the primary conductive marble 22 and the secondary conductive marble 24, and the lock cylinder PCB 12 performs key matching (electronic verification) on the chip 11 of the key 7. If the matching is successful, the control circuit enables the electromagnet 14 to execute the pin retracting action, so that the lock is unlocked; if the match fails, the control circuit does not execute any instructions and cannot unlock.

Referring to fig. 5, 6 and 7, fig. 5 is a schematic front view of a key; FIG. 6 is a schematic view of a key from the opposite side; fig. 7 is an isometric view of a key.

As shown, the front and back sides of the key 7 are respectively provided with the teeth 28, meanwhile, the front side is provided with a front PCB 29, the back side is provided with a back PCB 30, the chip 11 of the key 7 is located at the tail end of the front PCB 29, the front ends of the two PCB are respectively provided with a contact 31, and the contacts 31 are located at the root positions of the teeth 28, so that the contacts are contacted with the primary conductive marble 22 of the marble assembly 16 after being completely inserted, the conduction on the circuit is realized, and the key information in the chip 11 is read.

The above embodiments are merely preferred embodiments of the present invention, and are not limited thereto, and on the basis of these, specific adjustments may be made according to actual needs, thereby obtaining different embodiments. For example, a solenoid valve or a motor is used to drive the pin 17; alternatively, the pin assembly 16 may be provided on the rear side of the locking jamb locking mechanism 8, and so on. This is not illustrated here, as there are many possible implementations.

Because the pin shaft 17 of the electronic locking mechanism is in the retracted position when the travel switch 13 is not triggered, namely in the power-off state in which the key 7 is not inserted, the purpose that the legal key can be used for unlocking when the panel is not powered can be achieved, so that the problem that the key cannot be unlocked when the panel is powered off is solved, and when the travel switch 13 is triggered, namely in the power-on state in which the key 7 is inserted, the pin shaft 17 is in the extended position, the lock can be released only after the electronic verification is qualified, so that the lock cylinder 1 is opened by illegal technology (the key chip cannot be matched), the lock body cannot be opened, and meanwhile, if an illegal key or other objects are inserted into the lock cylinder 1, the travel switch 13 is touched, the pin shaft 17 is in the extended state, and the lock cylinder 1 can be prevented from being opened by physical technology.

After the key 7 is inserted into the lock core 1, besides mechanical verification, electronic ID verification is performed, unlocking can be performed only after mechanical and electronic simultaneous verification is passed, physical technology opening can be prevented, matching of an electronic key can be performed, integrated design of mechanical verification and electronic verification is realized, and safety of the lock core is remarkably improved.
