Description

An intelligent lock that automatically locks and unlocks and can reverse the lock tongue

technical field

The utility model belongs to the technical field of intelligent locks, in particular to an intelligent lock capable of automatically locking and unlocking and capable of inverting the lock tongue.

Background technique

The smart door lock market is developing rapidly, and the constant changes in appearance have put forward new requirements for the function of the lock body, such as many new cover plate shapes, the handle is fixed, and there is no structural function of lifting the lock and pressing down to unlock. The lock is required to have the function of automatic locking and unlocking; most of the automatic locks on the market are based on the existing mechanical locks, using the motor installed on the inner panel to drive the dial in the lock body to unlock and lock. The advantage of this method is that The structure is simple, but there are also disadvantages, that is, when the lock is unlocked, the oblique tongue is dragged and retracted in a horizontal line. When the door leaf is deformed or the door frame sealing strip is more elastic, a large vertical pressure will be generated on the oblique tongue of the lock, thereby increasing the size of the lock. The force of horizontal drag, to overcome such a large force, will inevitably increase the motor current. For smart locks using dry batteries, it will shorten the battery life and increase the frequency of battery replacement.

In order to solve the above problems, an intelligent lock that can automatically lock and unlock and can reverse the lock tongue is developed.

Extend, and the main latch assembly 03 simultaneously pulls the upper and lower bolt pull plates 0501 of the bolt pull plate assembly 05 to move upward and downward through its upper boss shaft 0302-2 and lower boss shaft 0302-1, respectively. When the gear boss 0903 rotates until it touches the second switch 1002 on the circuit board and closes it, the motor 15 stops working, the main tongue 0301 protrudes to the maximum limit, and the locking plate assembly is in the locking plate tension spring 12 The special-shaped groove 1101-2 on the locking plate 1101 catches the main bolt riveting shaft 0304 of the main bolt assembly 03, and the main bolt is locked at this time to complete the locking work.

During the door closing and locking process, the oblique tongue is in a raised state, and the oblique tongue 0201 rotates counterclockwise under the action of the oblique tongue torsion spring 0202. When the oblique tongue rotates to the edge of its tongue guide groove 0201-3, it touches the oblique tongue rod 0207 At this time, the thrust plate 0205 is rotated counterclockwise under the action of the thrust plate torsion spring 0204 until the limit arm 0205-4 of the thrust plate 0205 touches the oblique tongue. When the limit post 0207-6 on the rod, the thrust plate 0205 is limited and stopped, at this time, the pushing arm 0205-2 of the thrust plate 0205 is pressed against the pushing surface 0201-4 of the oblique tongue 0201, The oblique tongue is kept in a raised state, and the door will not fall down during the door closing process. Because the entire oblique tongue assembly 02 is elastically press-fitted on the lock housing through the oblique tongue spring 0209, when the oblique tongue structure closes the door, it pushes the oblique tongue 0201 to make the entire oblique tongue 0201. The tongue assembly is compressed into the inside of the lock body. After the pushing force is released, the whole tongue assembly rebounds outwards under the action of the tongue spring 0209, and at the same time the tongue enters the hole of the lock plate of the door frame to achieve locking and positioning.

automatic unlock

When unlocking, the control system receives the unlock command, the motor 15 rotates, and the gear 13 is driven by the motor gear 14 to finally make the lever gear 09 rotate clockwise. At this time, the gear boss 0903 on the lever gear 09 pushes the locking plate assembly upward. move to disengage the special-shaped groove 1101-2 on the locking plate 1101 from the main tongue riveting shaft 0304, release the locking plate to the main tongue plate, and complete the unlocking; then the gear boss 0903 continues to rotate, and the main tongue plate passes through the The gear slot 0303-1 drives the entire main bolt assembly 03 to move to the right, and retracts into the lock body along the main bolt hole 0101-2 of the bolt panel 0101, while the main bolt assembly 03 passes through its upper boss shaft 0302- 2 and the lower boss shaft 0302-1 pull the upper and lower bolt pull plates 0501 of the bolt pull plate assembly 05 to retract inside the lock body respectively; when the main lock tongue is fully retracted, the lock plate assembly is in the lock plate tension spring. 12 falls back, and the special-shaped groove 1101-2 on the locking plate 1101 catches the main bolt riveting shaft 0304 of the main bolt assembly 03 to complete the locking and positioning of the main bolt assembly; the gear boss 0903 continues to rotate clockwise , the gear boss 0903 touches the pull plate console 1702-2 on the pull plate 17 and drags the entire pull plate 17 to move downward. At the same time, the pull plate riveting shaft 1702 on the pull plate 17 drives the lever 18. The shifting fork 1802 swings clockwise, the shifting shaft 1803 of the shifting lever 18 drags the control end 0208-1 of the pulling rod 0208, so that the thrust plate 0205 starts to rotate, and the pushing arm 0205-2 of the thrust plate 0205 is completely separated from the slanting tongue 0201. On the push surface 0201-4, because the torsion spring force of the oblique tongue torsion spring 0202 is also very limited, when the door leaf is opened under the elastic force of the door frame sealing strip or the door is opened manually, the oblique tongue will automatically fall in the direction of opening the door.

The pull plate 17 continues to move downward, the third switch trigger point 1701-3 on the pull plate 17 touches the third switch 1003 on the circuit board and closes it, the motor stops working, the pull plate 17 stops moving downward, and dial The lever 18 also stops swinging. After a certain period of time (after opening the door), the motor rotates in the reverse direction, the pull plate 17 moves upward under the action of the pull plate spring 19, the lever 18 swings counterclockwise, the pull rod 0208 and the thrust plate 0205 are in the position of the thrust plate torsion spring 0204. Under the action of reset, the oblique tongue 0201 is reset under the action of the oblique tongue torsion spring 0202. At this time, the oblique tongue is in a raised state again, and the fourth switch trigger point 17-4 on the pull plate 17 touches and closes the first switch on the circuit board. Four switches 1004, the motor stops working, and the entire lock is in an initial standby state.
