[0025] like Figure 1 and Figure 2As shown, this high-security intelligent electric-controlled ignition switch lock includes a knob 2, a lock body 1, a lock core 4 and a lock core sleeve 3. The lock core sleeve 3 is rotatably arranged in the lock body 1, and the lock core 4 is rotatably arranged in the lock core sleeve 3. The knob 2 is connected to one end of the lock core 4, and the other end of the lock core 4 is linked to the transmission shaft 5. In order to realize the power on and off function, the utility model integrates a first micro switch 131 and a second micro switch 132 on the circuit board 13, as shown in FIG. Figure 2 and Figure 3 As shown, the transmission shaft 5 is connected with a rotating body 12, and the rotating body 12 is connected with a pressing part 120, and the pressing part 120 has an action inclined surface 1200; when the transmission shaft 5 drives the rotating body 12 to rotate, the action inclined surface 1200 of the pressing part 120 gradually acts on the first micro switch 131 or the second micro switch 132, so that the first micro switch 131 or the second micro switch 132 is pressed down; and when the first micro switch 131 is pressed, the circuit board 13 controls the whole vehicle circuit to be powered on, so that the vehicle can start normally; when the second micro switch 132 is pressed, the circuit board 13 controls the whole vehicle circuit to be powered off, so that the vehicle can be in a power-off state. Since the corresponding circuit is turned on and off by controlling the micro switch, not only the product stability and safety are increased, but also the life of the electric door lock can be increased.

[0026] Of course, if Fig.10 As shown, the first micro switch 131 here can be replaced by the first Hall switch 134, the second micro switch 132 can also be replaced by the second Hall switch 135, and the pressing part 120 is replaced by the magnet 121. When the transmission shaft 5 drives the rotating body 12 to rotate, the magnet 121 senses the first Hall switch 134 or the second Hall switch 135. When the first Hall switch 134 senses the magnet 121, the circuit board 13 controls the whole vehicle circuit to be powered on, so that the vehicle can start normally; when the second Hall switch 135 senses the magnet 121, the circuit board 13 controls the whole vehicle circuit to be powered off, so that the vehicle can be in a power-off state. Since the corresponding circuit is switched on and off by Hall switch induction, not only the product stability and safety are increased, but also the life of the electric door lock can be increased.

[0027] Generally, electronically controlled ignition switch locks have electronic unlocking methods (such as passwords, fingerprints, facial recognition, or electronic induction keys), so an electromagnet 8 is installed on the lock body 1 to control the rotation of the lock cylinder sleeve 3. When the electronic unlocking is successful, the electromagnet 8 no longer controls the lock cylinder sleeve 3, and turning the knob 2 can drive the lock cylinder sleeve 3 to rotate, and the transmission shaft 5 can also rotate. In order to control the operation of the electromagnet 8, the lock cylinder sleeve 3, the lock cylinder 4 and the transmission shaft 5 can move axially (which can also prevent accidental contact or misoperation by children), such as Figure 3As shown, a trigger 10 is provided on the transmission shaft 5, and a third micro switch 133 is integrated on the circuit board 13; when unlocking is required, the knob 2 is pressed to move the transmission shaft 5 axially inward, so that the trigger 10 acts on the third micro switch 133, and then the electronic unlocking method can be used. If the unlocking is successful, the circuit board 13 transmits a signal to the electromagnet 8, and the electromagnet 8 no longer controls the lock cylinder sleeve 3. Turning the knob 2 can drive the lock cylinder sleeve 3 to rotate, and the transmission shaft 5 can also rotate; in addition, a reset spring that can drive the lock cylinder 4 and the transmission shaft 5 to reset is provided in the lock body 1. After the knob 2 is pressed, the knob 2, the lock cylinder 4 and the transmission shaft 5 can be reset by the reset spring. It is worth mentioning here that the trigger member 10 can be replaced by a trigger magnet 137, and the third microswitch 133 can be replaced by a third Hall switch 136. When unlocking is required, the knob 2 is pressed to move the transmission shaft 5 axially inward, so that the trigger magnet 137 is sensed by the third Hall switch 136, and then the electronic unlocking method can be used. If the unlocking is successful, the circuit board 13 transmits a signal to the electromagnet 8, and the electromagnet 8 no longer controls the lock cylinder sleeve 3. Turning the knob 2 can drive the lock cylinder sleeve 3 to rotate, and the transmission shaft 5 can also rotate.

[0028] There are many electronic unlocking methods, such as using an electronic induction key. In this case, the circuit board 13 is connected to the controller, and the controller has a sensor for sensing the electronic key. When the knob 2 is pressed to make the trigger 10 act on the third micro switch 133, the sensor begins to sense whether the electronic key matches. If the electronic key matches, the controller controls the electromagnet 8 to operate, so that the knob 2 can be turned to unlock.

[0029] like Figure 3 As shown, the lock body 1 is connected to a base 16, the base 16 is connected to an electrical housing 11, and the circuit board 13 is installed in the electrical housing 11. In order to prevent the pressing part 120 from sliding when acting on the micro switch, a steel ball groove is provided on the rotating body 12, and a third spring 15 and a positioning steel ball 14 are provided in the steel ball groove. A positioning arc groove is provided on the base 16, and the positioning steel ball 14 enters the positioning arc groove under the action of the third spring 15. When the pressing part 120 acts on the micro switch, the positioning steel ball 14 just enters the positioning arc groove on the base 16 under the action of the third spring 15, so that the rotating body 12 will not slide, and the pressing part 120 can stably act on the micro switch.

[0030] When the matching key is inserted into the lock cylinder 4 and rotated, the lock cylinder 4 can drive the transmission shaft 5 to rotate; when there is no key, the knob 2 is turned, the knob 2 drives the lock cylinder 4 to rotate, and the transmission shaft 5 can also rotate. In order to achieve the above functions, Figure 4 and Figure 5As shown, a limiting groove 30 is provided on the outer surface of the lock core sleeve 3, and the limiting groove 30 is an axially extending long groove (because the limiting groove 30 of the lock core sleeve 3 is an axially extending long groove, it does not affect the axial movement of the lock core sleeve 3). Figure 6 As shown, there is a transition surface 31 between the bottom of the limiting groove 30 of the lock core sleeve 3 and the outer surface of the lock core sleeve 3, and a lock pin 9 that can move up and down is installed on the lock body 1. The lock pin 9 is inserted downward into the limiting groove 30 of the lock core sleeve 3 under the action of the fourth spring 90, as shown in FIG. Figure 5 As shown, the electromagnet 8 includes a coil, an iron core spring and an iron core 80. When the coil of the electromagnet 8 is energized, the iron core 80 can be retracted. The iron core 80 of the electromagnet 8 is located above the lock pin 9. The iron core spring can drive the iron core 80 to extend outward. When the iron core 80 of the electromagnet 8 is extended, the lower end of the lock pin 9 can be restricted in the limiting groove 30 of the lock core sleeve 3. In addition, as Figure 5 As shown, the lock core 4 is provided with a blade groove 40, in which a blade matching the key is provided (the blade is not shown), and the lock core sleeve 3 is provided with a slot 32 matching the blade; when the matching key is inserted into the lock core 4, the blade is disengaged from the slot 32 of the lock core sleeve 3.

[0031] The unlocking principle of this high-security intelligent electronically controlled ignition switch lock is as follows: when the key is not inserted, the lock pin 9 is inserted downward into the limiting groove 30 of the lock core sleeve 3 under the action of the fourth spring 90, and the iron core spring of the electromagnet 8 drives the iron core 80 to extend outward, limiting the lower end of the lock pin 9 in the limiting groove 30 of the lock core sleeve 3. In this way, when the knob 2 is turned, the lock core sleeve 3 is stuck by the lock pin 9, and the lock pin 9 has no space to move up, so that the knob 2 cannot be turned and the car cannot be started normally. When an unmatched key is inserted into the lock core 4, the blade in the lock core 4 is stuck in the locking groove 32 of the lock core sleeve 3. The lock cylinder sleeve 3 is stuck by the lock pin 9. When the key is turned, the lock cylinder 4 is stuck, so the key cannot be turned and the car cannot be started. When the matching key is inserted into the lock cylinder 4, the blade in the lock cylinder 4 disengages from the locking groove 32 of the lock cylinder sleeve 3. In this way, by turning the key and the lock cylinder 4, the lock cylinder 4 can drive the transmission shaft 5 to rotate, and the rotation of the transmission shaft 5 can drive the rotor switch to rotate, so that the ignition can be started normally. When the key is not brought, the electromagnet 8 can be energized by electronic unlocking methods such as passwords, fingerprints, facial recognition, or electronic induction keys. After the coil of the electromagnet 8 is energized, the iron core 80 is retracted. Figure 5As shown, there is space above the lock pin 9. When the knob 2 is turned, the lock core 4 rotates. Since the blade of the lock core 4 is stuck in the slot 32 of the lock core sleeve 3, the lock core sleeve 3 also rotates. Since there is a transition surface 31 between the bottom of the limit groove 30 of the lock core sleeve 3 and the outer surface of the lock core sleeve 3, when the lock core sleeve 3 rotates, the lock pin 9 comes to the outer surface from the bottom of the limit groove 30 of the lock core sleeve 3 along the transition surface 31. In other words, since there is space above the lock pin 9, when the lock core sleeve 3 rotates, the lock pin 9 is pushed upward by the lock core sleeve 3, so that the lock core 4 can drive the lock core sleeve 3 to rotate, and the lock core 4 drives the rotor switch to rotate through the transmission shaft 5, so that the ignition can be started normally. If the circuit fails and the electromagnet 8 is not energized, it can also be started by the key described above.

[0032] This high-security intelligent electronically controlled ignition switch lock has a reasonable structure and can be unlocked with or without a key. Moreover, since the iron core 80 of the electromagnet 8 is not directly subjected to force (the iron core 80 is only used to limit the space), the electromagnet 8 can be made very small, so that the overall appearance of the ignition switch lock can be made more compact, meeting the installation requirements of different models and being more applicable. Correspondingly, the smaller the solenoid valve, the lower the power and the power consumption, so it is more energy-saving and environmentally friendly.

[0033] like Figure 4 As shown, one end of the transmission shaft 5 is inserted into the non-circular hole 41 of the lock core 4. Figure 7 As shown, the reset spring includes a first spring sleeved on the lock core 4 and a second spring sleeved on the transmission shaft 5; one end of the first spring abuts against the support surface of the lock core 4, and the other end abuts against the transmission shaft 5, and the first spring can drive the lock core 4 to reset; one end of the second spring abuts against the transmission shaft 5, and the other end abuts against the lock body 1, and the second spring can drive the transmission shaft 5 to reset.

[0034] Finally, it is worth mentioning that Figure 8 As shown, the transmission shaft 5 includes a connecting portion 50, a toggle portion 51 and a transmission portion 52. The toggle portion 51 is located between the connecting portion 50 and the transmission portion 52 and is eccentrically arranged. The connecting portion 50 of the transmission shaft 5 is inserted into the non-circular hole 41 of the lock cylinder 4, and the transmission portion 52 is connected to the rotating body 12. The transmission shaft 5 is sleeved with a toggle plate 6, and the toggle plate 6 has a through hole 60 for the transmission shaft 5 to pass through. Fig. 9 As shown, an oblique hole 61 for the toggle part 51 to pass through is extended on one side of the through hole 60, and the toggle piece 6 is in transmission connection with the tap pin 7. When the knob 2 is pressed to make the lock core 4 drive the transmission shaft 5 to move forward, the toggle part 51 of the transmission shaft 5 moves into the oblique hole 61, and then the knob 2 is rotated, so that the transmission shaft 5 rotates. Since the toggle part 51 of the transmission shaft 5 is eccentric, the toggle part 51 of the transmission shaft 5 can drive the tap pin 7 to move telescopically through the toggle piece 6. The tap pin 7 is used to lock the front of the vehicle to prevent the front of the vehicle from rotating, thereby playing an anti-theft role.
