[0021] Embodiment: A fully automatic door lock body includes a lock housing 1, a main lock bolt assembly 2, a tilted bolt assembly 3, a tilted bolt baffle 4, a knob 5, a lock core, a push rod 6 and a motor 7. The main lock bolt assembly 2 and the tilted bolt assembly 3 are respectively slidably mounted in the lock housing 1. The main lock bolt 8 on the main lock bolt assembly 2 and the tilted bolt 9 on the tilted bolt assembly 3 can respectively extend a set distance outside the lock housing 1. The tilted bolt baffle 4 and the push rod 6 are movably mounted in the lock housing 1. The tilted bolt baffle 4 can prevent the tilted bolt 9 of the tilted bolt assembly 3 from sliding into the interior of the lock housing 1. The movement of the push rod 6 can drive the tilted bolt baffle 4 to move to achieve blocking or avoiding the tilted bolt 9. The knob 5 and the lock core are respectively rotatably mounted in the lock housing 1. The side wall of the knob 5 is provided with a radially extending The extended knob lever 10, the knob lever 10 can move the main lock tongue assembly 2 to slide back and forth, and is also provided with a knob gear 11, a transmission gear and a driving arm. The knob gear 11 and the transmission gear are respectively rotatably installed in the lock housing 1, and the knob gear 11 is engaged with the power output gear 12 at the power output end of the motor 7 for transmission. The rotation of the knob gear 11 can drive the knob 5 to rotate therewith, and the transmission gear is engaged with the knob gear 11 for transmission. The rotation of the transmission gear can drive the push rod 6 to move, and the driving arm is movably installed in the lock housing 1, and a radially extending lock rod is provided on the side wall of the lock core. The lock rod can move the driving arm, and the driving arm can drive the knob 5 to rotate and drive the push rod 6 to slide.

[0022] Electronic unlocking logic: The lock is initially locked. After the correct password is entered, the motor control circuit on circuit board 37 activates motor 7, which drives knob gear 11 to rotate. This rotation of knob gear 11 then drives knob 5. Rotation of knob 5 causes knob lever 10 on the knob to retract the main bolt assembly 2 into the lock housing 1, thereby unlocking the main bolt 8. Knob gear 11, while driving knob 5, also drives the transmission gear. The rotation of the transmission gear drives push rod 6, which in turn moves the latch bolt retainer 4 to avoid the latch bolt 9, thereby unlocking the latch bolt 9. The unlocked latch bolt 9 can now flip, unlocking the entire lock.

[0023] Mechanical door opening principle: the initial state of the lock is locked. Through the position of the lock hole on the lock body, the lock is rotated, and the lock lever on the lock rotates synchronously with the lock, thereby driving the driving arm to move, and the driving arm drives the knob 5 to rotate, and the rotation of the knob 5 unlocks the main lock tongue 8; the driving arm will drive the push rod 6 to move upward, and the push rod 6 will drive the inclined tongue baffle 4 to move to avoid the inclined tongue 9, thereby unlocking the inclined tongue 9. At this time, the unlocked inclined tongue 9 can be flipped, so that the entire lock is unlocked.

[0024] When unlocking electrically, the knob 5 is rotated to directly open the main lock tongue 8 and the oblique tongue 9 to unlock. When unlocking mechanically, the lock core is rotated to drive the knob 5 to rotate to unlock. There is no need to set a square bar mechanism in the lock body, and there is no need to turn the handle to open the door after unlocking. The door can be directly pushed and pulled after unlocking, which is convenient to open the door. It effectively simplifies the internal structure of the smart door lock, improves the assembly convenience of the smart door lock, reduces the manufacturing cost of the lock body, and makes the lock body thinner and more beautiful.

[0025] The structure in which the knob gear 11 rotates and drives the knob 5 to rotate is as follows: the knob 5 is further provided with an eccentric stopper 13, and the end surface of the knob gear 11 is provided with an arc-shaped limiting groove 14. The eccentric stopper 13 on the knob 5 can be slidably inserted into the arc-shaped limiting groove 14 of the knob gear 11, and the eccentric stopper 13 is stopped between the two side walls of the arc-shaped limiting groove 14. The rotating gear rotates under the drive of the motor 7. When it rotates a certain angle, the eccentric stopper 13 on the side wall of the knob 5 just slides onto one end of the arc-shaped limiting groove 14 on the end surface of the knob gear 11. It is blocked by the inner side wall of the arc-shaped limiting groove 14 and cannot slide forward further. At this time, the motor 7 continues to rotate, driving the eccentric stopper 13 to move together, and then driving the knob 5 to rotate together, thereby unlocking the main lock tongue 8. This structure allows the motor 7 to idle for a certain angle after being energized before unlocking, preventing technical unlocking.

[0026] The eccentric stopper 13 on the knob 5 is located on the outer circumferential wall thereof, and the knob gear 11 is rotatably sleeved on the outer side of the knob 5. This structure saves space inside the lock housing 1 and is easy to assemble.

[0027] The structure in which the rotation of the transmission gear can drive the push rod 6 to move is as follows: the transmission gear includes a primary transmission gear 15 and a secondary transmission gear 16, the primary transmission gear 15 is engaged with the knob gear 11 for transmission, and the secondary transmission gear 16 is engaged with the primary transmission gear 15 for transmission, an eccentric latch 17 is provided on the end surface of the secondary transmission gear 16, and the push rod 6 is provided with a step stop surface 18 perpendicular to its sliding direction, and the eccentric latch 17 is stopped on the step stop surface 18.

[0028] The eccentric latch 17 is driven by a two-stage gear transmission to match the movement direction of the push rod 6 with the rotation direction of the knob 5. The rotation of the knob 5 causes the eccentric latch 17 to synchronously move the step stop surface 18 on the push rod 6 through the two-stage gear transmission, so that the push rod 6 moves toward the direction of the latch baffle 4 of the latch bolt assembly 3, thereby blocking the latch baffle 4, so that the latch baffle 4 remains in a position that prevents the latch bolt 9 from moving inward. In addition to the structure in which the eccentric latch 17 cooperates with the step stop surface 18 on the push rod 6 to drive the push rod 6 to move, the transmission gear can also be other structures, such as a rack structure is provided on the side wall of the push rod 6, and the meshing transmission of the transmission gear and the rack structure on the side wall of the push rod 6 can also drive the push rod 6 to move. In addition to linear motion to drive the latch baffle 4, the push rod 6 can also adopt a swinging manner to push the latch baffle 4 to reciprocate by swinging. At this time, meshing teeth can be provided on the push plate to mesh with the transmission gear, or it can be eccentrically hinged with the transmission gear. This type of equivalent replacement structure is easily thought of by those skilled in the art based on this patent and falls within the scope of protection of this patent.

[0029] The structure in which the driving arm can drive the knob 5 to rotate is as follows: the driving arm is rotatably installed on the inner side of the lock housing 1, and the driving arm is provided with an elongated dial hole 20 extending along its radial direction, and the end of the lock head dial rod on the side wall of the lock cylinder is provided with a lock cylinder dial wheel extending along the axial direction of the lock cylinder, and the lock cylinder dial wheel is inserted into the elongated dial hole 20, and the driving arm is provided with an engaging gear piece 21, and the outer circumferential wall of the knob 5 is provided with an engaging tooth groove 22, and the engaging gear piece 21 on the driving arm is engaged with the engaging tooth groove 22 on the outer circumferential wall of the knob 5 for transmission.

[0030] When the lock cylinder is driven to rotate by the key, the lock cylinder dial wheel at the end of the lock rod drives the driving arm to rotate. The driving arm rotates through the meshing teeth on it and the meshing tooth grooves 22 on the knob 5, so that the knob 5 rotates synchronously with the driving arm, thereby achieving unlocking. In addition, the driving arm can also be installed in the lock housing 1 for linear motion. The lock cylinder dial wheel drives the driving arm to move linearly. A rack is provided on the driving arm, and the rack is meshed with the meshing tooth grooves 22 on the knob 5 to drive the knob 5 to rotate. This type of equivalent replacement structure is easily conceivable by those skilled in the art based on this patent and falls within the scope of protection of this patent.

[0031] The driving arm comprises an upper driving arm 23 and a lower driving arm 24, each of which is rotatably disposed at intervals within the lock housing 1. A meshing gear plate 21 is coaxially fixed to the upper driving arm 23. A passive toggle lever 25 extending radially from the circumferential outer wall of the upper driving arm 23 is further provided. An elongated toggle hole 20 is located on the lower driving arm 24. A first active toggle lever 26 extending radially from the circumferential outer wall of the lower driving arm 24 is provided. The end of the first active toggle lever 26 always maintains close contact with the side wall of the passive toggle lever 25 on the upper driving arm 23. Rotation of the lock cylinder drives the lower driving arm 24 to rotate via the lock cylinder dial wheel on the lock head dial lever. The first active toggle lever on the lower driving arm 24 rotates with the rotation of the lower driving arm 24, simultaneously toggling the upper driving arm 23. As the upper driving arm 23 rotates, the meshing gear plate on the upper driving arm engages with the meshing tooth groove 22 on the knob 5, driving the knob 5 to rotate.

[0032] A recess 27 is provided on the side wall of one end of the passive toggle rod 25, and an arc-shaped plug portion 28 is formed at the end of the first active toggle rod 26. The arc-shaped plug portion 28 can be inserted into the recess 27 on the side wall of one end of the passive toggle rod 25, and the side wall of the arc-shaped plug is stopped on the inner wall surface of the recess 27.

[0033] By setting a pit 27 on the side wall of one end of the passive toggle rod 25 and forming an arc-shaped plug portion 28 at the end of the first active toggle rod 26, the first active toggle rod 26 can be stably located at one end of the passive toggle rod 25, keeping the knob 5 in a locked state to prevent technical unlocking.

[0034] The structure of the driving arm that can drive the push rod 6 to slide is as follows: a second active toggle rod 29 extending radially thereof is provided on the outer circumferential wall of the driving arm, and a push rod transmission member 30 with a lever structure is rotatably provided in the lock housing 1, one end of the push rod transmission member 30 is stopped on the end surface of the push rod 6 facing away from the oblique tongue baffle 4, and the end of the second active toggle rod 29 on the driving arm is tightly against the side wall of the other end of the push rod transmission member 30. The second active toggle lever 29 is preferably arranged on the lower driving arm 24, and the second active toggle lever 29 on the lower driving arm 24 rotates with the lower driving arm 24 to toggle the push rod transmission member 30, and the push rod transmission member 30 pushes the push rod 6 to move to unlock the oblique tongue 9. In this way, after the lock cylinder rotates, the upper driving arm 23 is driven to rotate synchronously by the rotation of the lower driving arm 24 to realize the rotation of the knob 5. At the same time, the push rod transmission member 30 drives the push rod 6 to move, so that the angle of rotation of the knob 5 only needs to unlock the main lock tongue 8, and the push rod transmission member 30 realizes the pushing of the push rod 6 to unlock the oblique tongue 9. This structure realizes the synchronous unlocking of the main lock tongue 8 and the oblique tongue 9, and the unlocking is fast. It is separated from the unlocking mechanism of the motor 7 and will not interfere, thereby preventing the occurrence of unlocking failure.

[0035] The driving arm is also provided with a guide pin 31, and an arc-shaped guide groove is provided on the inner side wall of the lock shell 1. The guide pin 31 on the driving arm can be slidably inserted into the arc-shaped guide groove on the inner side wall of the lock shell 1. The lock shell 1 is also provided with a tilted bolt reset elastic member 32, a knob reset elastic member 33, a tilted bolt baffle reset elastic member 34 and a driving arm reset elastic member 35. The tilted bolt reset elastic member 32 provides an elastic reset force for the tilted bolt 9 to keep it extending out of the lock shell 1. The knob reset elastic member 33 provides an elastic retaining force for the knob 5 to move the main lock bolt assembly 2 so that the main lock bolt 8 on it extends out of the lock shell 1. The tilted bolt baffle reset elastic member 34 provides an elastic reset force for the tilted bolt baffle 4 to keep blocking the position of the tilted bolt 9. The driving arm reset elastic member 35 provides an elastic torsional force for the driving arm to rotate in the locking direction.

[0036] The guide pin 31 is preferably provided on the lower driving arm 24, and the driving arm reset elastic member 35 is preferably provided with a reset elastic torque to the lower driving arm 24. The lower driving arm 24 is guided by the guide pin 31 to ensure that the first active toggle rod 26 and the second rotation toggle rod thereon move synchronously with it during its rotation, to prevent it from tilting and interfering with the inner wall of the lock housing 1. The oblique tongue reset elastic member 32 is also used to realize that after the oblique tongue 9 loses the side wall stop of the oblique tongue 9 slot on the door frame, it automatically extends out of the lock housing 1, and the knob reset elastic member 33 is used to make the knob When the motor 7 and the lock cylinder are in the locked state, they automatically rotate in the opposite direction to push the main lock bolt 8 out of the lock housing 1 and maintain this state unchanged, thereby achieving stable locking and preventing technical unlocking. The latch bolt baffle plate reset elastic member 34 causes the latch bolt baffle plate 4 to automatically reset to a position that blocks the latch bolt 9 from moving into the lock housing 1 after it loses the push of the push rod 6. The drive arm reset elastic member 35 causes the lower drive arm 24 to automatically reverse to the locked state after it loses the rotational torque of the lock cylinder and maintains this state stably to prevent mechanical technical unlocking.
