Description

Smart lock with audio communication plug

technical field

The utility model relates to a lockset, in particular to an intelligent lock with an audio communication plug.

Background technique

With the development of electronic information technology, various smart locks have gradually entered people's lives, such as smart card door locks, fingerprint door locks, password door locks, radio frequency and Bluetooth door locks, etc. These smart locks can be roughly classified into two categories , One type requires an external information medium as a key to unlock the lock, and the other type uses data such as passwords and physical signs to unlock the lock without a key. These door locks requiring a key require the user to carry an additional key, and the key is too small to be easily lost and forgotten, and is too large to be carried around. The security of these door locks using passwords is poor. Too short passwords are insecure and too long, and it is easy to forget to unlock and enter the trouble. However, the use of fingerprints and other physical signs requires that only the owner can unlock the locks. It is inconvenient to use and requires additional input devices. Lock structure Complex and costly.

With the development of communication and information technology, digital products such as mobile phones have become indispensable for people to carry with them. The powerful functions of smart phones make people's lives more convenient and efficient, and people rely on them. The technology of using a mobile phone as a key to unlock the lock has also been developed, such as unlocking through mobile phone Bluetooth communication, unlocking through mobile phone near-field communication, etc., but the existing wireless communication unlocking communication connection is troublesome, and the wireless signal is easily shielded and interfered. The device hardware requirements are high.

Detailed ways

Example 1:

As shown in Figure 1-4, a smart lock with an audio communication plug includes a lock body 1, a left audio communication plug 2, a right audio communication plug 3, a traditional key jack 4, a lock installation hole 5, a power supply and a communication line 6. Door knob 7, spring 8, lock tongue 9, lock buckle 10, power switch part 11, power adapter conversion part 12, relay 13, signal conversion part 14, single-chip microcomputer 15, storage part 16, electromagnet 17, electromagnetic Iron control signal line 18, 5V power line 19, electromagnet attracting part 20, outer gear disc insulation part 21, outer gear disc conductive part 22, inner wheel disc 23, rotating arm 24, rack 25 and fixed conductor post 26. The left audio communication plug 2 on the left side of the traditional key jack 4 is an international standard 4-channel 3.5mm audio plug, and the right audio communication plug 3 on the right is a 4-channel 3.5mm audio plug of the American standard, which is located in the front of the lock body 1. Knob 7 in the door is located at the rear of lock rest 1; integrated with lock body 1; inside lock body 1, power switch 11; power adapter conversion part 12 and signal conversion part 14; single-chip microcomputer 15; Side; Relay 13 and dead bolt 9 fixed mounts are positioned at the left and right sides of lock body 1, spring 8 is placed on the crosspiece in the middle part of dead bolt 9 fixed mounts, and the middle part of lock body 1 is provided with electromagnet attracting part 20 and gear plate; The disc includes a fixed conductor column 26 contacting the insulating part 21 of the outer gear disc, the conductive part 22 of the outer gear disc and the inner disc 23; the rotating arm 24 is connected with the inner disc 23 and is interlocked with the hook on the top of the deadbolt holder 9; The plate and the lower part of the lock tongue 9 fixed frame are meshed with the rack 25, and the end of the rack 25 is equipped with an electromagnet attracting part 20, and the power supply and communication line 6 are respectively connected with the power switch 11 and the relay 13, and the power switch 11 is connected through a 5V power line 19 is connected with the power adapter conversion part 12, the storage part 16, the single-chip microcomputer 15 and the signal conversion part 14, and the relay 13 is respectively connected with the electromagnet 17 and the single-chip microcomputer 15 through the electromagnet control signal line 18.
