For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0047] In order to solve the problems in the prior art, the embodiments of the present specification provide a double-motor electronic lock cylinder device, an electronic lock device and a control method thereof. FIG. 1 and FIG. 2 show the overall structure of a double-motor electronic lock cylinder device in the embodiments of the present specification. The basic structure of the double-motor electronic lock cylinder device is described in the figures, and more or fewer units or components can be included based on conventional or non-inventive labor. The units or modules listed in the embodiments are only units or components divided according to functions. When the system or device product is executed in practice, the units and components can be adjusted.

[0048] As shown in FIG. 3 and FIG. 4, which are the exploded views of the components in the double-motor electronic lock cylinder device in the embodiments of the present specification, including a lock cylinder piece 3, a rotor 2 and a cylindrical shell 1 for accommodating the rotor 2 and the lock cylinder piece 3;

[0049] The inner wall of the shell 1 is provided with a shell groove 13;

[0050] The second end of the rotor 2 is a cylindrical first cavity, and the inner wall of the first cavity has a protrusion forming a limiting block 23. The first cavity is also provided with a rotor clamping groove 24, and a locking piece 21 is arranged in the rotor clamping groove 24. When the lock cylinder is in a locked state, the locking piece 21 is located inside the shell groove 13 and the rotor clamping groove 24, so that the rotor 2 and the shell 1 cannot rotate relative to each other, and the double-motor electronic lock cylinder device is in a locked state;

[0051] The lock cylinder piece 3 is cylindrical, and the first end of the lock cylinder piece 3 is inserted into the first cavity to form a rotatable connection with the rotor 2. The first end of the lock cylinder piece 3 is provided with an edge groove with an arc length greater than the limiting block 23 and at least one swing arm located in the edge groove. The swing arm is driven to rotate in the edge groove by two motors controlled by two circuit boards respectively, and the edge groove and the swing arm cooperate with the limiting block 23 to make the limiting block 23 move in the edge groove, forming a fixed state or a movable state;

[0052] The lock cylinder piece 3 is also provided with a lock cylinder piece groove 316. In the fixed state, the edge groove and the swing arm fix the limiting block 23, so that the lock cylinder piece 3 and the rotor 2 are relatively fixed in the axial direction. At this time, the lock cylinder piece groove 316 deviates from the rotor clamping groove 24;

[0053] In the active state, the swing arm is driven to rotate by a motor, so that the limiting block 23 can move in the edge groove, the lock core part 3 rotates by a certain angle to make the lock core part groove 316 of the lock core part 3 align with the rotor clamping groove 24, the locking part 21 is separated from the shell groove 13 and located in the rotor clamping groove 24 and the lock core part groove 316, so that the rotor 2 and the lock core part 3 are axially locked, the rotor 2 and the shell 1 are in a rotatable state, and the double-motor electronic lock core device is in an unlockable state.

[0054] The double-motor electronic lock core device using the embodiment of the present application comprises a lock core part, a rotor and a cylindrical shell for accommodating the rotor and the lock core part. The rotor clamping groove in the rotor and the locking part are matched with each other, so that the electronic lock core device can maintain the stability between the rotor and the shell in the locked state. The lock core part is rotatably connected in the cavity of the rotor, the lock core part is provided with an edge groove matched with the limiting block in the inner wall of the rotor, so that the rotor and the lock core part have a certain angular activity rotation space in the active state. The edge groove also has a swing arm driven to rotate in the edge groove by at least two motors, each motor is driven by a separate circuit board, and can be individually driven to rotate the swing arm to change the state between the lock core part and the rotor. At the same time, after changing the state between the lock core part and the rotor, the electronic lock can be unlocked by rotating the lock core part to drive the entire lock core into an unlockable state. Therefore, when the motor in the electronic lock core fails, the standby motor can be automatically called to control the swing arm by the motor, so that the double motors can independently complete the unlocking action, and the problem that the electronic lock cannot be unlocked when the motor in the electronic lock core fails in the prior art is solved.

[0055] As shown in FIG. 3 and FIG. 4, the electronic key 4 is provided with first key contacts 41A and second key contacts 41B on the front and back sides respectively, when the electronic key 4 is inserted into the anti-pick rotor core 35, as shown in FIG. 3, the first key contacts 41A of the electronic key 4 contact the first lock core electronic contacts 351A and the first elastic contacts 352A, then connect the first circuit board 321A in the second cavity of the lock core member 3 through the first circuit contacts 331A, thereby supplying power to the first circuit board 321A and outputting control signals to control the first motor 323 to drive the first swing arm 313 to unlock, at the same time, the first displacement sensor 322A cooperates with the sensing member 22 to sense whether the lock core member 3 and the rotor 2 have relative rotation; if there is no rotation, it means that the first circuit board 321A or the first motor 323 may have a fault, therefore the signal of no rotation is output to the electronic key 4, then the electronic key 4 needs to output control signals to enable the second key contacts 41B shown in FIG. 4, through contacting the second lock core electronic contacts 351B and the second elastic contacts 352B, connecting the second circuit contacts 331B to supply power to the second circuit board 321B and output control signals, to control the second motor 324 to drive the second swing arm 314 to unlock, and control the second displacement sensor 322B to cooperate with the sensing member 22 to sense whether the lock core member 3 and the rotor 2 have relative rotation.

[0056] In the embodiment of the present application, as shown in FIG. 5 and FIG. 6, the main functions of the electronic lock core are realized by the lock core part 3 and the rotor 2, wherein the rotor 2 mainly plays a role of connecting between the lock core part 3 and the outer lock shell 5, so that the lock core part 3 can be unlocked by two motors respectively and independently. The first end of the lock core part 3 is inserted into the first cavity of the rotor 2, so that the two parts are rotatably connected. The protruding limiting block 23 on the inner wall of the rotor 2 and the edge slot of the first end of the lock core part 3 are matched, so as to limit the rotation angle of the rotor 2 and the lock core part 3. Meanwhile, by rotating the lock core part 3 at a certain angle, the relative position relationship between the lock core part groove 316 and the rotor clamping groove 24 can be adjusted. As shown in FIG. 7, the locking part 21 is pushed by the lock core part 3 to a protruding state, which is matched with the shell groove 13 in the outer shell 1, so that the rotor 2 and the outer shell 1 are in a locked state. When the lock core part 3 is rotated to a certain angle, as shown in FIG. 8, the lock core part groove 316 of the lock core part 3 is aligned with the rotor clamping groove 24, so that the locking part 21 can fall into the lock core part groove 316 to be separated from the outer shell groove 13, so that the outer shell 1 and the rotor 2 can be rotated. The outer shell 1 and the tail cover 36 are combined and fixed by the screw 11, so that the rotor 2 and the lock core part 3 are stably connected in the outer shell and can only rotate axially, thereby ensuring the stability of the entire lock core. In FIG. 5, the first displacement sensor 322A is arranged in the first through hole 311A, and the second displacement sensor 322B is arranged in the second through hole 311B. The two displacement sensors are respectively connected to two circuit boards and can be matched with the sensing part 22 to independently sense whether the rotor 2 and the lock core part 3 have relatively rotated.

[0057] In the embodiment of the present application, in order to realize that the two motors can respectively and independently drive the swing arm to make the rotor 2 and the lock core part 3 enter an active state, as shown in FIG. 12a-FIG. 12b and FIG. 13a-FIG. 13b, the swing arm includes a first swing arm 313 and a second swing arm 314.

[0058] The first swing arm 313 is driven by the first motor 323 to rotate along the axial direction. The outer end away from the axis of the lock core part 3 is used to fix the limiting block in the fixed state. The inner end close to the axis of the lock core part 3 is abutted with the second swing arm 314.

[0059] The second swing arm 314 is driven by the second motor 324 to rotate along the axial direction, and drives the inner end of the first swing arm 313 to rotate, thereby driving the first swing arm 313 to rotate.

[0060] The swing arm further includes a resilient part 315, which is used to drive the inner end of the first swing arm 313 to rotate to the position of the outer end of the first swing arm 313 in the fixed state after the first motor 323 or the second motor 324 stops driving.

[0061] Specifically, the process shown in FIGS. 12a-12b is the process of driving the first motor 323 to rotate the first swing arm 313 along the axial direction, so that the outer end of the first swing arm 313 is misaligned with the inclined edge of the limiting block 23, and the limiting block 23 can rotate in the edge groove of the lock cylinder 3; the process shown in FIGS. 13a-13b is the process of driving the second motor 324 to rotate the second swing arm 314 along the axial direction, so that the second swing arm 314 abuts against the inner end of the first swing arm 313 to rotate, and the outer end of the first swing arm 313 is misaligned with the inclined edge of the limiting block 23, so that the second motor 324 can drive the first swing arm 313 and the limiting block 23 to form an active state by working alone.

[0062] In another embodiment of the present specification, the same first swing arm 313 can also be rotated by two motors, as shown in FIG. 13a, the first motor 323 is unchanged, and the second motor 324 is replaced by a push motor that directly acts on the inner end of the first swing arm 313. When the second motor 324 is needed to work, it pushes the inner end of the first swing arm 313, so that the outer end of the first swing arm 313 is misaligned with the inclined edge of the limiting block 23, and the second motor 324 can also drive the first swing arm 313 and the limiting block 23 to form an active state by working alone.

[0063] Meanwhile, as shown in FIGS. 12c-12d or FIGS. 13c-13d, the other side of the inner end of the first swing arm 313 also has a resilient component 315. After the first motor 323 or the second motor 324 stops driving, the inner end of the first swing arm 313 can be driven by elasticity to rotate the outer end of the first swing arm 313 to the position in the fixed state. Then, by continuing to rotate the lock cylinder 3, the relative positional relationship between the lock cylinder groove 316 of the lock cylinder 3 and the rotor clamping groove 24 is adjusted. When the lock cylinder 3 is rotated to a certain angle, the lock cylinder groove 316 of the lock cylinder 3 is aligned with the rotor clamping groove 24, so that the locking piece 21 can fall into the lock cylinder groove 316 to be in a position away from the locking state and away from the shell groove 13, so that the shell 1 and the rotor 2 can rotate.

[0064] In the embodiment of the present specification, in order to determine which motor to use for driving, as shown in FIG. 3, the lock cylinder 3 further comprises,

[0065] The second end of the lock cylinder 3 is a cylindrical second cavity, and a double circuit board is connected in the second cavity. The double circuit board is connected with the first motor 323, the second motor 324, and a displacement sensor respectively. The relative position between the bottom of the first cavity and the displacement sensor is provided with a sensing component 22.

[0066] The circuit board comprises a first circuit board 321A and a second circuit board 321B.

[0067] The displacement sensor comprises a first displacement sensor 322A and a second displacement sensor 322B;

[0068] The first circuit board 321A is connected to and controls the first motor 323 and the first displacement sensor 322A.

[0069] The second circuit board 321B is connected to and controls the second motor 324 and the second displacement sensor 322B.

[0070] Specifically, the displacement sensor controlled by each circuit board needs to determine whether the circuit board and the motor on the circuit board can normally operate. By determining whether the double-motor lock cylinder device can normally be unlocked, it is determined whether the motor can normally work, and a signal is output to the electronic key 4, another key contact is replaced to enable another circuit board and the motor and displacement sensor connected thereto. At the same time, the information of the unlocking key can be accurately recorded in the case of normal unlocking, and each displacement sensor can independently monitor whether the lock cylinder is rotated in real time, and power is cut off after rotation is monitored to save power and improve the service life of the battery.

[0071] In an embodiment of the present specification, in order to enable the displacement sensor to monitor whether the lock cylinder is rotated in real time,

[0072] The displacement sensor is a Hall sensor,

[0073] The relative position between the bottom of the first cavity and the Hall sensor is provided with a magnetic component, which cooperates with any of the Hall sensors to detect whether the rotor 2 and the lock cylinder piece 3 are relatively rotated.

[0074] Specifically, the magnetic component is fixedly connected to the rotor 2, and when the rotor 2 and the lock cylinder piece 3 are relatively rotated, the Hall sensor can sense the displacement of the magnetic component, thereby detecting whether the rotor 2 and the lock cylinder piece 3 are relatively rotated.

[0075] In another embodiment of the present specification, the displacement sensor is a photoelectric sensor,

[0076] The relative position between the bottom of the first cavity and the photoelectric sensor is provided with a light sensing component, which cooperates with any of the photoelectric sensors to detect whether the rotor 2 and the lock cylinder piece 3 are relatively rotated.

[0077] Specifically, the displacement sensor 322 can also be a photoelectric sensor, and the rotor 2 is fixedly provided with a light sensing component, which is a through hole with light transmission and a reflective film without light transmission. The displacement of the light transmission through hole sensed by the photoelectric sensor in use can also achieve the same effect as the Hall sensor.

[0078] In the embodiment of the present application, as shown in FIG. 9 and FIG. 10, in order to drive the lock cylinder to rotate by the key, the lock cylinder 3 further comprises,

[0079] The anti-picking rotor core 35 is arranged in the second cavity and fixedly connected with the lock cylinder 3, used for plugging the electronic key 4 and driving the lock cylinder 3 to rotate; the inner wall of the anti-picking rotor core 35 is provided with the first lock cylinder electronic contact 351A and the second lock cylinder electronic contact 351B, used for abutting against the first key contact 41A and the second key contact 41B of the electronic key 4, obtaining the electric energy provided by the electronic key 4, and transmitting the electric energy to the first circuit board 321A or the second circuit board 321B of the lock cylinder 3.

[0080] Specifically, as shown in FIG. 9, the first circuit board 321A, the second circuit board 321B, the connecting piece 33 and the anti-picking rotor core 35 are sequentially arranged in the second cavity of the lock cylinder 3, the inner wall of the anti-picking rotor core 35 is provided with the first lock cylinder electronic contact 351A and the second lock cylinder electronic contact 351B, which are connected with the first circuit contact 331A and the second circuit contact 331B on the connecting piece 33, connecting the first circuit board 321A and the second circuit board 321B; after the key 4 is inserted into the anti-picking rotor core 35, the first lock cylinder electronic contact 351A or the second lock cylinder electronic contact 351B is controlled to contact the key contact according to the control signal, so as to supply power to the first circuit board 321A or the second circuit board 321B; the ball 312 cooperates with the dustproof baffle 34 to preliminarily unlock.

[0081] Further, in order to realize the unlocking of the circuit board by the key 4, the control instruction needs to be obtained from the key, therefore, the lock cylinder 3 further comprises,

[0082] The signal of the displacement sensor is transmitted to the electronic key 4 through the lock cylinder electronic contact, so that the electronic key 4 outputs the control instruction according to the signal;

[0083] Further, the processing unit is arranged to control the first motor 323 on the first circuit board 321A to drive the first swing arm 313 by the first key contact 41A, or control the second motor 324 on the second circuit board 321B to drive the second swing arm 314 by the second key contact 41B according to the control instruction of the electronic key 4.

[0084] On the other hand, in order to ensure the sensitivity of the two lock cylinder electronic contacts in the anti-picking rotor core 35, a dustproof baffle 34 is needed to prevent the anti-picking rotor core 35 from being easily polluted, therefore, as shown in FIG. 9 and FIG. 11a, the lock cylinder 3 further comprises the dustproof baffle 34,

[0085] The dustproof baffle 34 is shaped to fit the inner groove of the anti-picking rotor core 35, and the dustproof baffle 34 is connected with elastic devices 341, so that the dustproof baffle 34 resists the second cavity when not under pressure.

At the same time, the first displacement sensor 322A cooperates with the sensing component 22 to sense whether the lock cylinder 3 and the rotor 2 are relatively rotated; if not, it means that the first circuit board 321A or the first motor 323 may have a fault, so the signal of no rotation is output to the electronic key 4, and the electronic key 4 outputs a control signal to enable the second key contact 41B.

If the electronic key permission verification is not a problem, it indicates that the first motor 323 may have failed, causing the first swing arm 313 to be unable to rotate, so that the rotor 2 cannot enter an active state.

[0119] It is determined whether the permission verification is successful;

[0120] If the permission verification is not successful, the unlocking is stopped;

[0121] If the permission verification is successful, the electronic key 4 supplies power to any motor in the lock cylinder 3 that drives at least one swing arm.

The electronic key 4 determines which motor in the current electronic lock cylinder is the main motor according to the preset number of times and the historical unlocking information of the current electronic lock cylinder, and switches another motor as the main motor after the main motor unlocking reaches the preset number of times, thereby ensuring that the use frequencies of the two motors are similar and ensuring the reliability of the double-motor electronic lock cylinder.
