The spring assembly 16 is used both to trigger the travel switch 13 and to read the chip information of the key 7, while performing two functions, it is electrically connected to the cylinder PCB board 12 of the electronic locking mechanism.

Lock core 1 and lock sleeve 2 are equipped with corresponding marble hole in the front side of locking side column locking mechanical system 8, be equipped with one-level insulating cover 21 and the electrically conductive marble 22 of one-level in the marble hole of lock core 1, the downthehole electrically conductive cover 23 of second grade and the electrically conductive marble 24 of second grade of being equipped with of marble of lock sleeve 2, the electrically conductive marble 22 of one-level and the electrically conductive marble 24 of second grade are connected with lock core PCB board 12 electricity, the electrically conductive marble 24 of second grade links with travel switch 13, can trigger travel switch 13, wherein, the electrically conductive marble 24 of second grade both can be connected with lock core PCB board 12 electricity all the time, also can be connected with lock core PCB board 12 electricity after removing.

When the key 7 is inserted, a chip signal on the key 7 is conducted with the lock cylinder PCB 12 through the primary conductive ball 22, the secondary conductive ball 24 and the conductive spring 27.

The structure is only a specific way for the secondary conductive marble 24 to simultaneously realize the triggering and reading functions, and on the basis, other different linkage ways of the secondary 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 secondary conductive ball 24, and the tail of the secondary conductive ball 24 is used as a trigger to trigger the travel switch 13, meanwhile, in order to achieve conduction between the secondary conductive ball 24 and the key cylinder PCB 12, the secondary conductive ball 24 may be electrically connected to the key 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 another embodiment, the travel switch 13 is located on one side of the secondary conductive ball 24, but the secondary conductive ball 24 is not provided with the notch 25, but is provided with a lateral boss or lug, and when moving upwards, the travel switch 13 is triggered by the lateral boss or lug, and the rest of the structure is basically the same as that of the first embodiment.

Because the electronic locking mechanism only needs to be provided with one group of the spring assemblies 16 to realize the triggering and reading functions, the switch spring assemblies and the password reading spring assemblies do not need to be separately arranged, 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 a thinner thickness, the types of compatible doors are more, and 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 when a key is inserted into a small portion; fig. 4 is a schematic view of the internal structure of the mechatronic lock shown in fig. 1 in a state where the key is fully inserted.

As shown, when the travel switch 13 is not triggered, the pin 17 exits the locking groove 18, in the unlocked position; when the travel switch 13 is triggered and the electronic verification is not performed, the pin 17 enters the locking groove 18 and is in the 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 located at an unlocking position; when the travel switch 13 is triggered and the electronic verification is not qualified, the pin 17 is kept in the state of entering the locking groove 18, and is in the locking position.

The working principle is as follows:

when the key 7 is not inserted into the lock cylinder 1, the pin 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 electrified.

When the key 7 is inserted into the lock cylinder 1, the front end of the key 7 is in contact with the first-stage conductive marble 22, the travel switch 13 is further triggered by the second-stage conductive marble 24, the panel powers on the lock cylinder PCB 12, and the pin 17 of the chip control electromagnet 14 on the lock cylinder PCB 12 extends out and is inserted into the locking groove 18 of the lock cylinder 1. When the lock cylinder 1 is illegally and technically 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 contacts 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 will make the electromagnet 14 execute the pin shaft retracting action, thereby unlocking the lock; if the matching fails, the control circuit does not execute any instruction, so that the lock cannot be unlocked.

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

As shown in the figure, the front and the back of the key 7 are respectively provided with a tooth 28, meanwhile, the front is provided with a front PCB 29, the back 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 PCBs are both provided with contacts 31, the contacts 31 are located at the root position of the tooth 28, so as to contact with the first-level conductive balls 22 of the ball component 16 after being fully inserted, thereby realizing the conduction on the circuit and reading the key information in the chip 11.

The above embodiments are merely preferred embodiments of the present invention, and are not limited thereto, and on the basis of the above embodiments, various embodiments can be obtained by performing targeted adjustment according to actual needs. For example, a solenoid valve or a motor is used to drive the pin 17; alternatively, the bullet assembly 16 is provided on the rear side of the locking side post locking mechanism 8, and so on. This is not illustrated here, since many implementations are possible.

Because the pin 17 of the electronic locking mechanism is in the retraction position when the travel switch 13 is not triggered, namely, in the power-off state that the key 7 is not inserted, the purpose of unlocking by a legal key can be realized when the panel is not powered, thereby solving the problem that the key cannot be unlocked when the panel is powered off in the current intelligent lock cylinder, and moreover, when the travel switch 13 is triggered, namely, in the power-on state that the key 7 is inserted, the pin 17 is in the extension position, only after the electronic verification is qualified, the locking can be released, so that when the lock cylinder 1 is unlocked by an illegal technique (the key chip cannot be matched), the lock body cannot be unlocked, meanwhile, if an illegal key or other objects are inserted into the lock cylinder 1, the travel switch 13 can be triggered, so that the pin 17 is in the extension state, and the lock cylinder 1 can be prevented from being unlocked by a physical technique.

After the key 7 is inserted into the lock cylinder 1, besides mechanical verification, electronic ID verification is also needed, unlocking can be performed only after the mechanical and electronic verification is passed, physical technology unlocking can be prevented, matching of electronic keys can be performed, the integrated design of mechanical verification and electronic verification is realized, and the safety of the lock cylinder is obviously improved.

The mechatronic lock provided by the invention is described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the core concepts of the present invention.
