Description

Technical Field

[0001] This invention relates to a new multifunctional anti-theft door lock. Background Technology

[0002] Currently, there are three main types of security door locks: mechanical security door locks, remote control security door locks, and smart security door locks. Mechanical security door locks are convenient to use but have poor anti-theft performance. Remote control security door locks are difficult to promote due to unreasonable design. Although smart security door locks have high technological content, they are difficult to popularize due to their high price and poor resistance to damage. Therefore, the current locks have their own shortcomings. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects of existing anti-theft door locks and provide a new multi-functional anti-theft door lock. The lock's features include: installing the electronic control unit on the door frame, effectively solving the power supply problem and achieving maintenance-free operation; and installing the lock body in the door leaf for convenient key unlocking. The multi-functional anti-theft door lock offers three unlocking modes: remote control, mobile app unlocking, and key unlocking. When there is no 220V power supply, the lock automatically switches from remote control / mobile app unlocking to key unlocking. When there is a 220V power supply, the lock automatically switches from key unlocking to remote control / mobile app unlocking, thereby improving the anti-theft capability of the multi-functional anti-theft door lock. This lock also features a doorbell function and voice prompts for unlocking or locking, thus meeting the needs of different users.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: A new multi-functional anti-theft door lock consists of an electronic control part and a lock body; wherein the electronic control part consists of: a 220V power supply, a step-down and step-up circuit, a remote control and APP circuit, an unlocking actuator, a doorbell and voice prompt circuit, an automatic locking circuit, a power failure control circuit, and an unlocking mode switching mechanism; the 220V power supply is connected to the step-down and step-up circuit, which is connected to the automatic locking circuit, the remote control and APP circuit, and the power failure control circuit respectively; the remote control and APP circuit is connected to the automatic locking circuit and the unlocking actuator respectively; the automatic locking circuit and the unlocking actuator are connected to the doorbell and voice prompt circuit; the power failure control circuit is connected to the unlocking actuator and the unlocking mode switching mechanism respectively; the unlocking actuator and the unlocking mode switching mechanism are connected to the lock body.

[0005] The unlocking execution mechanism and unlocking mode switching mechanism of the electronic control section consist of: a first side strip, a slanted latch lock box, an obstacle switch, a first limit switch, a second limit switch, a first geared motor bracket, a first geared motor, a first slider, a function switching push rod, a square latch lock engagement, a third limit switch, a second slider, a second geared motor, a fourth limit switch, a second geared motor bracket, and an electronically controlled latch. The first side strip is connected to the slanted latch lock box, the first geared motor bracket, the square latch lock engagement, and the second geared motor bracket. The slanted latch lock box is connected to the obstacle switch. The first geared motor bracket is connected to the first limit switch, the second limit switch, and the first geared motor. The first geared motor is connected to the function switching push rod, and the function switching push rod is connected to the first slider. The second geared motor bracket is connected to the third limit switch, the fourth limit switch, and the second geared motor. The second geared motor is connected to the electronically controlled latch, and the electronically controlled latch is connected to the second slider.

[0006] The lock body comprises: a lock body box, a second side strip, a slanted bolt, a functional toggle mechanism, a key locking toggle mechanism, a square bolt, a square bolt tension spring, a fixing bolt, a sign toggle mechanism, a latch, a key unlocking toggle mechanism, a key unlocking toggle mechanism tension spring, a pivot, a sign, a lock cylinder, and a lock body box cover. The lock body box is connected to the slanted bolt, functional toggle mechanism, key locking toggle mechanism, square bolt, square bolt tension spring, fixing bolt, sign toggle mechanism, latch, key unlocking toggle mechanism, and key. The unlocking mechanism has a tension spring and a pivot connection. The function mechanism is connected to the latch. The latch is connected to the square bolt and the key unlocking mechanism. The square bolt is connected to the key locking mechanism and the square bolt tension spring. The square bolt tension spring is connected to the lock body box. The key locking mechanism is connected to the lock cylinder and the key locking mechanism tension spring. The key locking mechanism tension spring is connected to the lock body box. The sign mechanism is connected to the pivot. The pivot is connected to the sign. The lock body box cover is connected to the lock body box.

[0007] Working Principle: The 220V power supply is stepped down and rectified to power this lock. When the 220V power supply is normal, this lock can only be unlocked remotely or via a mobile app. After unlocking, the lock emits a "unlocked" voice message and simultaneously sends an unlocking signal to the main control mobile phone, which also facilitates verification of the person opening the door. After automatically locking the door, the lock emits a "locked" voice message, and at the same time, a sign blocks the lock cylinder and keyhole. This serves two purposes: first, it prevents the lock cylinder and keyhole from being damaged; second, the sign displays the word "closed," indicating that the door is locked. When there is no 220V power supply, the lock automatically switches to key unlocking mode. The electric bolt automatically retracts, and the square bolt automatically engages, achieving a seamless connection. At the same time, the sign opens the lock cylinder and keyhole, creating conditions for key unlocking. Attached Figure Description
