The beneficial effect of this application is as follows:
it should be clear that the structure of the present application is such a locking and unlocking structure for an electronic lock.
This application belongs to electronic locking unlocking structure, is applicable to electronic lock, intelligent lock trade, and other structure scenes that need lock the unblock.
The main drive power of this application comes from the motor, and the motor cooperation motor plectrum through corotation reversal drive unblock locking structure.
The present application does not specifically limit the type and type of the drive motor 14, and it is clear that mutually equivalent technical features are also within the scope of protection of the present application.
The unlocking process of the application is as follows:
in each unlocking process, the driving motor 14 reversely rotates for 75 milliseconds and then keeps the position for 20 milliseconds, the motor plectrum 141 is used for impacting the overturning pressure plate 15, the rotating force is changed into downward pressure through the structure, downward pressure of about 5 newtons is applied to the clutch pin 16, the clutch pin 16 is pressed down for about 8MM, the clutch pin 16 is inserted into the hole in the rotating shaft, and the unlocking state is completed.
Under the unblock state, pivot and pivot bottom plate 13 are fixed through separation and reunion round pin 16, and when the user drove pivot bottom plate 13 through the handle this moment and rotate, pivot and pivot bottom plate 13 also can rotate the same angle simultaneously, and the rotation of pivot can drive the lock body and realize that the spring bolt of reality is flexible, realizes the complete unblock of locking structure.
The locking process is as follows:
during each locking process, the driving motor 14 rotates forwards for 75 milliseconds and then keeps the position for 20 milliseconds, so that the motor pull tab 141 releases the overturning pressing sheet, and the motor pull tab 141 returns to the initial position. At the moment, the rotary pressing sheet is separated from the motor end and is not stressed completely, the other end of the pressing sheet is compressed between the clutch pin 16 and the rotating shaft bottom plate, the clutch pin spring generates 2 newtons of elasticity to eject the clutch pin 16 upwards, and the overturning pressing sheet 15 is jacked to the limiting position. At this time, the clutch pin 16 is completely released from the hole of the rotating shaft, and the rotating shaft base plate 13 are in a separated state. At this point locking is complete.
Under the state of locking, pivot and pivot bottom plate 13 are structural not interconnect, and when the user drove the pivot bottom plate through the handle this moment and rotate, the pivot still kept vertical state, and pivot bottom plate 13 no matter rotates left or right and all has no influence to the pivot, is in the idle running commentaries on classics attitude, is in the lock body structures such as the spring bolt with the pivot linkage all the time in the lock state, unable unblock.
The design of this application changes the mode of original complicated gear motor with gear train direct drive into locking unblock separation and reunion control mode, and the motor need not locking structures such as direct drive spring bolt, and the actual unblock is accomplished through handle linkage structure. The design mode greatly reduces the requirement on the driving force of the motor, directly removes a gear driving structure, reduces the volume of the whole structure and reduces the technical requirement.
The key point of the structural design is that the motor plectrum 141 is used for impacting the structure of the turnover pressure plate 15 to realize the insertion of the clutch pin 16, and the springback force of the spring of the clutch pin 16 is used for realizing the ejection of the clutch pin 16. The mutual structure cooperation of the clutch pin 16, the rotating shaft and the rotating shaft bottom plate 13 converts the insertion and ejection of the clutch pin 16 into the rotation of an external handle to drive unlocking and locking, thereby realizing a novel electronic lock locking structure through simple electromechanical and structure cooperation.
The structural design greatly simplifies the locking structure of the original electronic lock, reduces the volume to about half of the original volume, can put the structure into more small-volume electronic locks, and increases the feasibility of more products.
The mode of adding the gear set into the original gear motor is modified into the mode of adding the clutch pin into the common motor, so that the cost of the motor is reduced, moving parts such as gears and the like are reduced, the noise is reduced, and the structural reliability is improved.
Compared with the prior art, the utility model relates to a locking release mechanism 1 for electronic lock through set up axis of rotation 12 simultaneously and with axis of rotation 12 swing joint's pivot bottom plate 13 has seted up rotatory through-hole 132 in the pivot bottom plate 13, the one end position 121 of axis of rotation 12 runs through and inserts among the rotatory through-hole 132, still include upset clamp plate 15, be used for the drive 15 axial pivoted driving motor 14 of upset clamp plate and be used for right axis of rotation 12 with the synchronous rotation of pivot bottom plate 13 carries out unblock locking clutch pin 16, 15 one end of upset clamp plate with the output shaft of driving motor 14 matches the butt joint each other the drive of driving motor 14 rotates certain angle down, the other end of upset clamp plate 15 with clutch pin 16 matches the butt joint each other, makes clutch pin 16 removes certain distance, is provided with on the pivot bottom plate 13 to be used for running through clutch pin 16's spacing post 131 the axis of rotation 12 the end position 121 seted up with clutch pin 16's end position matches each other, realizes unblock locking hole 122 of locking, the one end of unblock locking clutch pin 16 passes through stretch into behind spacing post 131 in the through-hole 132, with the mutual matching of rotatory hole 122, the high locking hole 122, the reliability of motor has realized unlocking motor 14, has realized that the reliability and has realized that the reliability is high reliability and has realized that the motor has not used the advantage of motor structure design, has reached the high reliability and has simple structure design, has realized unlocking motor structure design and has realized unlocking motor.
