Technical field

The present application relates to electronic locks, and in particular, to an electronic lock core with anti-illegal unlocking characteristics with idling characteristics, a control method thereof, and a system with an electronic lock core.

Background technique

With the continuous development of electronic lock technology, electronic lock cylinders belonging to the category of passive electronic locks occupy a certain market due to their advantages of small size, low price, and flexible application. Such electronic lock cylinders often use micro-electromagnets or micro-motors as the driving mechanism due to their volume limitations.

Chinese Patent Authorization Bulletin No. CN202266107U "An Electronic Lock with Emergency Numerical Control Cylinder" adopts the installation of inductive contacts and electromagnets in the cylinder core sleeve of the mechanical lock cylinder. After the electromagnetic coil is energized, the iron core is driven to lock the mechanical lock cylinder and prevent it from rotating normally; when the key is legally inserted to unlock the solenoid, the electromagnetic coil is not energized, and the lock can be unlocked normally.

Chinese Patent Authorization Announcement No. CN204531692U "Leaf Electronic Locks and Electronic Keys" uses inductive contacts and motors to be installed in the lock cylinder sleeve of the mechanical lock cylinder. When the inductive contacts detect the illegal key unlocking, the bearing is driven by the motor after power is applied Drive the unlocking cam to rotate, so that the unlocking ball cannot be smoothly withdrawn from the blind hole of the mechanical lock cylinder, so that the mechanical lock cylinder cannot rotate normally; and when the key is legally inserted to unlock the lock, the motor will not be powered on, so the unlocking ball can be removed from the mechanical lock cylinder Withdraw from the blind hole, the mechanical lock cylinder can rotate normally.

The bile connecting piece drives the structure at the rear end to unlock; while preventing illegal unlocking, the lock itself is locked by an electromagnet located at the rear end of the lock to prevent it from rotating.

Although the above several typical electronic locks with the function of preventing illegal mechanical unlocking can achieve this purpose, due to the small structure of the electronic lock core itself, the iron core that can be installed in the mechanical lock core or the size of the unlocking marble itself is limited, which leads to its own Insufficient strength; in the normal control of illegal mechanical unlocking, the mechanical lock core is locked by the iron core or unlocking bullet to prevent it from rotating. If the key is forcibly violently twisted, it will easily cause the mechanical lock to be locked. The iron core or unlocking bullet of the core is damaged, deformed or even broken. In light, the control of the mechanical lock core is invalidated and the electronic lock core is illegally opened.

Specific implementation method

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by the ordinary skilled in the art without any creative labor shall fall within the protection scope of this application.

In order to facilitate the understanding of the content of this application, the following uses an electronic lock cylinder that can be applied to many occasions for description; and in the following description, according to daily habits, the "clockwise rotation" of the electronic lock cylinder is set as the unlocking action. The “counterclockwise rotation” cannot be unlocked; it can be understood that only a slight adjustment of the corresponding mechanical structure can be converted into the “counterclockwise rotation” of the electronic lock cylinder as the unlocking action, and the actual control method has not changed substantially. . This should not be taken as a limitation on this application, but should all belong to the protection scope of this application.

Embodiment 1: An electronic lock core with anti-illegal unlocking characteristics with idling characteristics.

As shown in Figure 1, it is a schematic diagram of an explosion structure of an electronic lock core with anti-illegal unlocking characteristics with idling characteristics; Figures 2 and 3 are schematic diagrams of the internal structure of the electronic lock core before the key is inserted; it can be seen that the electronic The lock cylinder is composed of a lock cylinder sleeve 101 and a front lock cylinder 201 and an electronic rotor 301 installed in a lock cylinder hole 1011 of the lock cylinder sleeve 101.

It can be seen that the rear end of the front lock cylinder 201 has a 4mm deep front snap groove 206, and forms a 6mm cavity with the 2mm deep rear snap groove 3011 at the front of the electronic rotor 301; The electric control composed of the coil 401, the iron base 405, the iron core 402, the iron core spring 404, and the clamping block 403. The electromagnetic coil 401 is located in the coil mounting hole 3012 of the electronic rotor 301, and the iron base 405 is located in the electromagnetic coil 401. The rear end extends into the core moving hole 4011, the core 402 and the core spring 404 are located in the core moving hole 4011 on the axis of the electromagnetic coil 401, and the core 402 with permanent magnetism can be in the core moving hole 4011. Move back and forth along the axis; the block 403 is an oval structure with a thickness of 4mm. The axis of the iron core 402 overlaps with the center point of the block 403 and is firmly connected. When the electronic lock cylinder is closed, the block 403 driven by the iron core 402 It can be retracted and retracted freely in the front snap groove 206 and the rear snap groove 3011.

When the iron core 402 extends relative to the electromagnetic coil 401, the iron core spring 404 stretches, and when the clamping block 403 is only located in the front snap groove 206, turning the front lock core 201 can drive the clip through the front snap groove 206 403 rotates coaxially, while the iron core 402 rotates in the iron core moving hole 4011 without affecting the electronic rotor 301, and the electronic rotor 301 cannot be rotated together; when the iron core 402 is retracted 2mm relative to the electromagnetic coil 401, The magnetic attraction generated by the iron core 402 and the iron base 405 allows it to overcome the force of the compressed iron core spring 404, and the clamping block 403 moves backward 2mm at the same time and is located in the rear snap groove 3011 and the front snap groove 206 Inside, rotating the front lock cylinder 201 can synchronously drive the electronic rotor core 301 to rotate coaxially through the block 403.

It can be seen that a set of snap springs 202 and springs 203 are installed in the front lock cylinder 201, which includes one or more sets of push rod springs 204; usually in the locked state, the springs are pushed by the springs 203 The tab 202 protrudes from the outside of the front lock cylinder 201, and prevents the front lock cylinder 201 from rotating by restricting it with the limiting groove in the lock cylinder sleeve 101; only the key matching the respective spring leaf 202 is fully inserted into the front When the keyhole of the lock cylinder 201 is set, each key can be made by a key that is completely matched with the set of card springs 202 by convex teeth, bumps, or recesses, or grooves, or grooves on the key. 202 is fully retracted into the front lock cylinder 201, and the front lock cylinder 201 is rotated by a key, as shown in FIGS. 4 and 5. It can be understood that the front lock cylinder 201 serves as the first safety precaution of the electronic lock cylinder. Only a perfectly matched key can cause the front lock cylinder 201 to rotate. At present, various mechanical lock cylinders have almost improved the anti-unlocking performance of the technology. They are all used in the spring leaf 202 or marbles. In this embodiment, there are no restrictions on the shape of the snap spring 202 or the marble in the key and the front lock core 201.

It can be seen that the front lock cylinder 201 also contains a lock cylinder push rod 501 controlled by the push rod spring leaf 204. The rear end of the lock cylinder push rod 501 also has a push rod spring 502. Cooperating with the pusher gear 503, the pusher gear 503 is used to drive the latching pusher 504 that can extend into the front latching groove 206. When the key is inserted into the front lock cylinder 201, the pusher spring plate 204 is pushed to run, and the lock cylinder push rod 501 is moved backward by the spring plate 202. The lock cylinder push rod 501 drives the push rod gear 503 to rotate and push the card block. The lever 504 moves forward and exits the front buckle groove 206, as shown in FIG. 4 which is the internal structure diagram of the key cylinder push rod 501 when the key is inserted into the front lock cylinder 201, and FIG. 5 is the push button when the key is inserted. The lever is disengaged from the clamping block 403. Figure 6 shows the idling of the electronic rotor 301 after the key is fully inserted, and Figure 7 shows the electronic rotor 301 coaxially rotated to unlock after the key is inserted; and the key is pulled out of the front lock core 201 At this time, the lock cylinder push rod 501 moves forward to the initial position under the action of the push rod spring 502, as shown in FIGS. 2 and 3.

It can be understood that, when the key is inserted into the front lock cylinder 201, the push rod spring piece 204 moves under the action of the key, thereby driving the lock cylinder push rod 501 to move accordingly. The movement of the push-rod clip spring 204 can be caused by the thickness of the key itself when the key is inserted, it can also be caused by the convex teeth or bumps on the key, or it can be caused by the convex groove or groove on the key. Wherein, the thickness of the key used in this embodiment causes movement of the push-rod clamping spring 204. In this regard, the various ways in which the key causes the movement of the push-rod clamping spring 204 should be regarded as the protection scope of the present application.

Further, the front lock cylinder 201 adopts a structure with an idling function in daily life, so that it can be idled in daily life, and the front snap groove 206 located behind it is separated from each other, and the two have passed similar patent application numbers. CN201610397998.2 "An idling anti-violence intelligent lock" is connected with a lock cylinder connecting piece, and at the same time, the lock cylinder connecting piece can also have the function of a push rod assembly. When the key is inserted, the front locking groove 206 can be driven only after the lock bladder connecting piece is moved upward, and the forward / backward movement of the lock cylinder push rod 501 is replaced by the upward / downward movement. Similar structures can also be constructed in other ways, and after all, the key is inserted into the front lock cylinder, and the lock cylinder push rod 501 can finally generate forward / backward through the action between the key and the lock cylinder push rod 501. The function of movement, and finally the effect on the iron core block, should be regarded as the protection scope of this application.

It can be understood that the push rod assembly composed of the lock cylinder push rod 501, the push rod gear 503, and the block push rod 504 can also be constructed in other ways. For example, the push rod assembly is only composed of the lock core push rod 501, and the lock is inserted when the key is inserted. The core push rod 501 moves backward and comes out of contact with the protruding block 403, or the push rod assembly is directly composed of the lock core push rod 501. When the key is inserted, it is driven by the push rod spring piece 204 The lock cylinder push rod 501 moves forward, or backward, or radially inward of the lock cylinder, or radially outward of the lock cylinder. The rear end of the lock cylinder push rod 501 directly produces forward, or backward, or toward the lock cylinder. Move radially inward, or radially outward of the lock cylinder. Alternatively, the rear end of the lock cylinder putter 501 is similar to a “Z” -shaped structure, and the center of the “Z” shape is fixed. When the lock cylinder putter 501 moves forward, the tail end moves backward, or the lock cylinder putter 501 moves backward. Drive the tail forward when moving. There are many such structures, and the ultimate purpose is to drive the push rod assembly to achieve movement through the action of key insertion, which should be regarded as the scope of protection of this application.

It can be seen that there is a sensor switch located in the lock core sleeve 101 for sensing the movement of the card spring piece 202 when the key is inserted. When the key is inserted, the card spring piece 202 retracts into the front lock core 201, and when the key is pulled out, the card spring The sheet 202 protrudes from the outer wall of the front lock cylinder 201 under the action of the circlip spring 203. Through the slight change in the position of the above-mentioned snap spring 202, the induction switch senses the unlocking action of the key. It can be understood that the inductive switch can be a variety of detection switches, such as using a probe to detect whether a metal object is inserted, or a probe to detect whether the position of the card spring piece 202 has changed (contact or not with the probe); or using a miniature pressure Whether the position of the inductive snap spring 202 of the sensitive switch changes, etc., shall be regarded as the protection scope of the present application.

In this embodiment, the used iron core 402 includes a permanent magnet, and the electric control also has an iron base 405 at the end of the electromagnetic coil 401. When the electromagnetic coil 401 is powered off and the core 402 is retracted relative to the electromagnetic coil 401, a magnetic attraction force is generated between the core 402 and the iron base 405, so that the core 402 can overcome the compression of the core spring 404 to the core 402. The external force keeps the state retracted relative to the electromagnetic coil 401. When the electromagnetic coil 401 is energized (or forward), the electromagnetic coil 401 generates an outward magnetic repulsive force on the iron core 402, which destroys the core 402. In a balanced state, the iron core 402 is extended outward relative to the electromagnetic coil 401. After the iron core 402 is extended outward, the electromagnetic coil 401 is powered off (it can also be considered that the electromagnetic coil is momentarily energized). At this time, the iron core 402 and iron The magnetic attraction force due to the increase in distance between the mass bases 405 is weakened, and the role of the core spring 404 cannot be overcome to keep the core 402 in an extended state with respect to the electromagnetic coil 401. It can be understood that electrical controls with this type of function can also have other similar structural functions, such as the iron base 405 is magnetic, and the iron core 402 is only a material that can be magnetically adsorbed, the same function can also be achieved. However, it is also possible to use an electrical control consisting of only a clamping block 403, a spring, an electromagnetic coil 401, and an iron core 402 fixed in the electromagnetic coil 401. The clamping block 403 and the iron core 402 are not connected, and the iron core 402 is magnetic. The block 403 is a material that can be magnetically adsorbed. When the electromagnetic coil 401 is powered off, the clamping block 403 compresses the spring and generates magnetic attraction with the iron core 402 to maintain the retracted state relative to the electromagnetic coil 401. When the electromagnetic coil 401 is energized, the force balance of the clamping block 403 is destroyed, and Making the clamping block 403 extend under the action of the spring can also achieve the above purpose.

It can be seen in FIGS. 1 to 7 that the front snap groove 206 at the rear end of the front lock core 201 and the rear snap groove 3011 at the front end of the electronic rotor 301 match the oval-shaped block 403. The internal dimensions of the groove 206 and the rear buckle groove 3011 are slightly larger than the outer dimensions of the clamp block 403. When the iron core moves forward and backward along the axis in the core movement hole 4011, the clamp block 403 can follow the front buckle groove. 206. The cavity formed by the rear snap groove 3011 is free to move. In Figs. 2, 3, 4, and 7, the clamping block 403 is located at the position of the front snap groove 206 and the rear snap groove 3011 at the same time; in Figs. 5 and 6, the key is completely inserted into the front lock cylinder 201 Then, the key drives the front lock cylinder 201 to rotate, and through the front buckle groove 206, the key block 403 located only in the front buckle groove 206 is rotated together, so that the electronic lock cylinder is idling; in FIG. 7 In the middle, the block 403 is located in the front snap groove 206 and the rear snap groove 3011 at the same time. The key drives the front lock cylinder 201 to rotate, so that the electronic rotor 301 rotates coaxially through the block 403, and the electronic lock cylinder is On.

The central axis of the electronic lock core is a shaft for rotation; when the block 403 is only located in the front buckle groove 206, turning the front lock core 201 by the key will drive the iron core block to rotate together, but not after The buckle groove 3011 rotates, and the iron core 402 rotates in the iron core moving hole 4011 without causing any damage to the iron core moving hole 4011. With this structure, the electromagnetic coil 401 achieves control of the iron core block, It will not cause the electronic rotor core 301 to be damaged due to the use of violence, which effectively protects the electronic devices in the electronic rotor core 301 from being damaged by the violence.

It can be understood that, in order to achieve the above purpose, even the clamping block 403 has a circular structure, and the iron core 402 and the clamping block 403 are not connected at the center position of the clamping block 403. Thus, when the clamping block 403 is driven by the front buckling groove 206 It is still possible to make the iron core 402 rotate only on the axis. In this regard, all should be regarded as the protection scope of this application.

It can be understood that in this embodiment, when the iron core 402 is extended relative to the electromagnetic coil 401, the locking block 403 is disengaged from the rear locking groove 3011, so that the electronic lock core is idling; in another configuration, only the rear The depth of the buckle groove 3011, when the iron core 402 is retracted relative to the electromagnetic coil 401, the clamp block 403 is separated from the front buckle groove and is only located in the rear buckle groove 3011. The electronic lock core can also be idled. Only when the iron core 402 is extended relative to the electromagnetic coil 401, the locking block 403 is extended and then is located in the front buckling groove 206 and the rear buckling groove 3011, and then the lock can be unlocked. This should also be regarded as the scope of protection of this application.

The rotation of the electronic rotor 301 drives the transmission lock tongue 601 to rotate coaxially. The transmission lock tongue 601 is used to open a matching mechanical structure for door opening. It can be understood that, in some applications, the electronic rotor 301 and the transmission lock tongue 601 can be fused, and the rear end structure of the electronic rotor 301 directly forms the function of controlling the unlocking of the transmission tongue 601. In this regard, it should be regarded as the protection scope of this application.
