Description

Technical Field

[0001] This invention relates to the field of smart door lock technology, and in particular to a mechatronic smart lock with multiple security locking mechanisms. Background Technology

[0002] The gearboxes in existing smart locks integrate complex transmission structures into the housing, enabling modular installation and bringing convenience to the smart lock industry. However, the internal structure of existing gearboxes typically consists of a motor, a worm gear assembly, and a large end wheel. During operation, the motor drives the worm gear to rotate, and the worm gear meshes with the large end wheel. When the motor is powered off, the worm gear assembly stops rotating, and the large end wheel is stuck and cannot rotate. This poses a safety hazard for users escaping from indoors in an emergency, resulting in low reliability. Furthermore, it cannot restrict unauthorized unlocking. When using swipe or password unlocking, the handle still needs to be pressed down for auxiliary unlocking, making the unlocking method limited and unable to achieve fully intelligent unlocking.

The shielding iron tube 72 is housed inside the mounting housing 71, and the rear plug iron pad 73 and the washer 74 are arranged sequentially from back to front inside the rear end of the shielding iron tube 72. The electromagnetic coil 75 is housed inside the shielding iron tube 72 via a frame 751, with the rear end face of the frame 751 fitting against the end face of the washer 74. The copper tube 76 is housed within the frame of the electromagnetic coil 75. The rear end is located inside the center hole of the washer 74; the strong magnet 77, the demagnetizing element 78, and the spring A79 are arranged sequentially from back to front inside the rear section of the copper tube 76; the iron moving pin 710 has a stepped shaft structure and is arranged inside the front section of the copper tube 76. The stepped part at the rear end of the iron moving pin 710 is matched with the front end of the spring A79. A retaining ring is provided on the stepped part at the front end of the iron moving pin 710. The copper baffle 711 is arranged on the open front end of the mounting shell 71. The copper baffle 711 is provided with a U-shaped opening groove. The front end of the iron moving pin 710 passes through the U-shaped opening groove and matches the U-shaped opening groove of the copper baffle 711 through the stepped part at the front end of the iron moving pin 710.

[0038] The latch assembly 8 includes a latch 81, a moving rod 82, a spring B83, and a sliding end plate 84. The moving rod 82 is slidably disposed in the mounting groove of the lock's rear housing. The latch 81 and the sliding end plate 84 are respectively disposed on both ends of the moving rod 82. The spring B83 is disposed on the outer edge of the moving rod 82 between the mounting groove and the rear end of the latch 81. The rear side of the sliding end plate 84 is slidably disposed in the limiting groove of the lock's rear housing. The rotating arms 572 of the upper fork 57 and the lower fork 58 are respectively located on the front and rear sides of the moving rod 82 and are correspondingly disposed with respect to the sliding end plate 84. The rotating arms 572 of the upper fork 57 and the lower fork 58 are used to move the sliding end plate 84 to drive the latch 81 to extend and retract.

[0039] When the lock control main board detects sufficient power, it controls the right-angle reversing clutch power group 3, the mechanical linkage component 4, and the clutch component 5 to operate in tandem, while the semi-automatic unlocking power group 6 and the magnetic retaining lock 7 are in the disengaged state. In the locked state, the two swing wheels 38 of the right-angle reversing clutch power group 3 are disengaged from the teeth of the double-ended gear 312. The round iron 314 on the rear side of the outer end actuating arm 3121 and the positioning magnet 313 exert a magnetic force, forcing the actuating arm 3121 of the double-ended gear 312 to be in a horizontal position. When the lock control main board receives an unlocking signal, it controls the DC motor 32 to operate, and the worm gear 34, worm 33, and bridge... Wheel 35 and middle wheel 36 mesh and drive in sequence. Middle wheel 36 drives the swing wheel 38 corresponding to the unlocking to mesh with the teeth of double-headed gear 312, thereby rotating double-headed gear 312. During the rotation, the actuating arm 3121 actuates the teeth 211 of the large slide plate 21 and the arc-shaped part 432 at the lower end of the clamping plate 43, causing the large slide plate 21 to move horizontally backward and the clamping plate 43 to move upward. During the movement of the large slide plate 21, it drives the top and bottom rods 44 and the pull rod 42 to move. The pull rod 42 and the clamping plate 43 respectively actuate the pull rod actuating arm 511 and the clamping plate actuating arm 512 on the clutch housing 51. Since the moving pin 55 is not pressed down by the clutch bearing 65, the housing 51 rotates freely.

[0040] When the large sliding plate 21 moves, it drives the locking tongue assembly and the reed switch 26 located on the electronic main board 25 to move. When the reed switch 26 moves to correspond with the magnet 27 installed on the upper lock shell 1, the magnet 27 applies a magnetic field to the reed switch 26 to magnetize it, causing the reed switch 26 to be triggered to close, instantly connecting the power supply to make the circuit conduct. The NE555 chip 252 illuminates the multi-color self-circulating LED beads 24 according to the set time control. The colored light of the LED beads 24 shines through the transparent cover plate 23. When the timer ends, the LED beads 24 turn off.

[0041] When the large sliding plate 21 and the main locking bolt 22 are fully retracted into the lock housing 1, the actuating arm 3121 continues to rotate and contacts the lower side of the push plate 41 behind the large sliding plate 21. The actuating arm 3121 generates an upward thrust on the push plate 41. Since the push plate 41 is provided with a vertical long sliding hole, under the action of the thrust and the torsion spring, the push plate 41 moves upward along the long sliding hole. The upper end of the push plate 41 contacts the right-angle push point 573 of the upper shift fork 57, pushing the upper shift fork 57 to rotate backward. The rotating arm 572 on the upper fork 57 drags the sliding end plate 84 of the tongue assembly 8, pulling the tongue 81 back and automatically completing the entire unlocking process; during the rotation of the toggle arm 3121, the sensing magnet 3122 and the Hall element 315 sense each other, and the Hall element 315 outputs a switch signal to the lock control main board to control the DC motor 32 to stop after completing the unlocking process at a specified time, and controls the DC motor 32 to rotate in the opposite direction so that the balance wheel 38 disengages from the double-headed gear 312.

[0042] During the locking process, the DC motor 32 reverses, which in turn drives the components to reverse or retract. When the middle wheel 36 reverses, it switches the other swing wheel 38 to mesh with the double-headed gear 312. When the locking state is reached, the swing wheel 38 of the right-angle reversing clutch power group 3 disengages from the double-headed gear 312, leaving operating space for the mechanical key to unlock and lock. When the mechanical key is used to unlock or lock, the control board will not send an electronic signal. Since the double-headed gear 312 and the swing wheel 38 are disengaged, when the mechanical key drives the square rod at the tail of the lock cylinder to rotate, the double-headed gear 312 rotates and drives the lever arm 3121 to move the large sliding plate 21 of the lock and drive the main lock tongue 22 to unlock or lock.

[0043] When the control board detects insufficient power, it controls the semi-automatic unlocking power unit 6, the mechanical linkage component 4, and the clutch component 5 to work together, while the right-angle reversing clutch power unit 3 and the magnetic retaining lock 7 are in the disengaged state. When the control board receives an unlocking signal, it controls the motor 62 of the semi-automatic unlocking power unit 6 to operate, and the rotating shaft 64 of the motor 62 begins to rotate. During the rotation, the rotating pin 641 causes the floating springs 66 to rotate to the lower side of the rotating pin 641, thereby pushing the clutch shoe 65 downward. The clutch shoe 65 contacts the moving pin 55 of the clutch component 5, pressing the moving pin 55 down into the housing 51. The lower end of the moving pin 55 corresponds to the upper part of the arc-shaped rotating block 521 at the rear end of the moving core. The moving core is connected to the outer casing 51. At this time, the control board prompts that the door lock can be opened. The person opening the door presses the outdoor handle, and the moving core rotates. Then, through the action of the moving pin 55 and the limiting boss 513 inside the outer casing 51, the handle drives the outer casing 51 to rotate within a limited angle range. The plate lever arm 512 and the lever lever arm 511 on the outer casing 51, through the linkage of the plate 43 and the lever 42 with the large sliding plate 21, pull back the main lock tongue 22 to unlock. At the same time, the arc-shaped support platform 515 on both ends of the outer casing 51 cooperates with the arc-shaped limiting groove 571 on the upper fork 57 and the lower fork 58 to drive the upper fork 57 and the lower fork 58 to rotate and pull back the oblique tongue 81 to achieve semi-automatic unlocking; the locking process is the reverse process.

[0044] When the lock body is in the normal locked state, the electromagnetic coil 75 is not energized, and the iron moving pin 710 is attracted by the strong magnet 77. The iron moving pin 710 is in the retracted position, and the retaining ring on the iron moving pin 710 contacts the copper baffle 711, compressing the spring A79. When illegal or technical unlocking is used, the control board detects that the key is an unverified illegal key. When the electromagnetic coil 75 receives a high-level signal from the control board, the electromagnetic coil 75 is energized, generating a magnetic field. The magnetic field cancels out the magnetic force of the permanent magnet. Under the action of the spring A79, the iron moving pin 710 extends instantaneously and contacts the baffle 212 on the large sliding plate 21, blocking the large sliding plate 21 from moving further. This causes the main bolt 22 to be stuck halfway outside the lock body, making illegal or technical unlocking fail and preventing the door from being opened. This achieves the true safety function of the electromechanical integrated safety mechanism.
