[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0029] Example:

[0030] As attached Figure 1 To be continued Figure 7 As shown:

[0031] This utility model provides an intelligent American standard door lock, including a front lock 11, a rear lock 12, and a square latch 13; the front lock 11 includes a front shell 19, a front cover plate 112, a control component 130, a fingerprint module 110, a blade lock cylinder 14, a camera module 17, and a PIR sensor 16; the rear lock 12 includes a rear shell 119, a rear cover plate 115, a motor clutch assembly 133, and a magnet box 137.

[0032] The front cover 19 has a touch port 127, a sensor hole 146, and a lock cylinder hole 131. The fingerprint module 110 is exposed through the touch port 127 to acquire fingerprint information. The camera module 17 is fixed to the camera bracket 129, which is fixed in the bracket groove 128 of the front cover 19 with screws and waterproofed with a rubber ring. The lens cover 18 is fixed to the surface of the front cover 19 for waterproofing with adhesive and screws. The photosensitive sensor 145 is exposed through the photosensitive hole 149 to detect light, and the camera module 17 is exposed through the camera hole 148 to capture and record video, etc. The R sensor 16 and millimeter-wave radar 143 are fixed inside the front cover 19 for detecting the presence or movement of a human body outside the door; the fingerprint module 110 is adhesively fixed inside the touch port 127 of the front cover 19 and pressed and waterproofed by the camera bracket 129; the blade lock cylinder 14 is adhesively fixed inside the lock cylinder hole 131 of the front cover 19 and pressed and waterproofed by the front cover plate 112; the touchpad motherboard 15 is screwed into the touchpad slot 139 of the front cover 19, with a plastic bracket 113 separating the Bluetooth signal; the TF card 144 is located inside the front cover 19 for data storage and management; the lens 142 is adhesively attached to the surface of the front cover 19 for waterproofing. The blade rod 117 is inserted into the blade rod slot 122 of the knob 123, and the front lock 11 is connected to the rear lock 12 through the blade rod 117. When unlocking with a fingerprint, after the fingerprint information is verified, the motor clutch assembly 133 rotates forward, driving the knob 123 to rotate. The knob 123 then drives the vane rod 117 to rotate, retracting the square tongue 13 inward and disengaging it from the door strike hole, thus unlocking the door. When locking, the motor clutch assembly 133 rotates in reverse, driving the knob 123 to rotate. The knob 123 then drives the vane rod 117 to rotate the square tongue 13, causing it to extend and insert into the door strike hole, thus locking the door. When unlocking with a key, the key rotates forward, driving the square rod to rotate the square tongue 13 inward and disengaging it from the door strike hole, thus unlocking the door. When locking, the key rotates in reverse, driving the vane rod 117 to rotate the square tongue 13, causing it to extend and insert into the door strike hole, thus locking the door.

[0033] The front cover plate 112 is provided with a first cable outlet groove 132 and a TF card slot 150. The limiting bracket 114 is fixed to the front cover plate 112 by screws, and then fixed to the front shell 19 by screws and pressing the blade lock cylinder 14.

[0034] The control component 130 is located inside the front cover 19 and is fixed to the front cover 19 by screws. The fingerprint module 110 is exposed through the touch port 127 to receive fingerprint signals and obtain fingerprint information.

[0035] The blade lock cylinder 14 is located inside the front housing 19. The blade lock cylinder 14 is fixed to the lock cylinder hole 131 of the front housing 19 with adhesive backing and is pressed and waterproofed by the front cover plate 112. When unlocking with a key, the blade rod 117 is inserted into the blade rod groove 122 of the knob 123. The front lock 11 is connected to the rear lock 12 through the blade rod 117. When the key is turned clockwise, it drives the blade rod 117 to rotate and the square tongue 13 retracts inward, so that the square tongue 13 disengages from the door strike hole to achieve the purpose of unlocking.

[0036] The camera module 17 is located inside the front cover 19 and exposed through the camera hole 148 on the lens cover 18. It takes pictures and records videos. When a stranger lingers or loiters at the door, the camera module 17 will capture a photo and send it to the user's mobile phone after being detected by the PIR sensor 16 and the millimeter-wave radar 143, thus protecting the user's home security 24 hours a day.

[0037] The rear housing 119 has a knob hole 140. A knob 123 is inserted into the knob hole 140 and fixed with a retaining ring 121. The motor clutch assembly 133 is fixed to the rear housing 119 with screws, and the square rod of the knob 123 is inserted into the square rod slot 141 of the motor clutch assembly 133. When the motor clutch assembly 133 rotates, it drives the knob 123, which in turn drives the vane rod 117 to rotate. The front lock 11 is connected to the rear lock 12 through the vane rod 117. The power board 135 is fixed to the rear housing 119 with screws. A Hall sensor 134 is installed inside the rear housing 119 to detect the door opening and closing status. A magnet box 137 is installed on the door frame. After the door is opened, when it slowly closes and is basically parallel to the door frame, the Hall sensor 134 and the magnet box 137 sense each other and automatically lock. The rear cover 119 is equipped with a normally open button 126 and a deadbolt button 125. When the normally open mode is activated, the square tongue 13 disengages from the door latch hole, which is convenient for users who frequently enter and exit. When the deadbolt mode is activated, the rear lock 12 is equipped with a Hall sensor 134, and the motor clutch assembly 133 does not rotate, so the lock cannot be opened, thus protecting the user's privacy. Rotating the rear lock 12 unlocks the door and simultaneously cancels the deadbolt mode.

[0038] The rear cover 115 is provided with a second cable outlet groove 138, which is fixed to the rear shell 119 by screws.

[0039] The motor clutch assembly 133 is located inside the rear housing 119 and has a square rod slot 141. The square rod of the knob 123 is inserted into the square rod slot 141 of the motor clutch assembly 133. When the motor clutch assembly 133 rotates, it drives the knob 123 to rotate. The front lock 11 is connected to the rear lock 12 via the blade rod 117. When unlocking with a fingerprint, after the fingerprint information is verified, the motor clutch assembly 133 rotates clockwise, driving the knob 123 to rotate. The knob 123 drives the blade rod 117 to rotate, causing the square tongue 13 to retract inward, allowing the square tongue 13 to disengage from the door strike hole to achieve the purpose of unlocking.

[0040] The magnet box 137 is attached to the door frame to detect the door opening and closing status. After the door is opened, when it slowly closes and is basically parallel to the door frame, the Hall sensor 134 and the magnet box 137 sense each other and automatically lock.

[0041] The Bluetooth APP unlocking function allows users to connect to the smart door lock via Bluetooth using a mobile APP and verify their identity. Once verified, the lock will unlock.

[0042] This door lock can be unlocked via fingerprint, password, Bluetooth, or emergency key, avoiding the inconvenience caused by lost keys, forgotten keys, or inconvenient keys to carry. It also features door opening / closing status detection for automatic locking. Furthermore, it includes a camera module 17, a PIR sensor 16, and a millimeter-wave radar 143, enhancing home security monitoring and providing theft prevention. It is easy to use, breaking free from the limitations of a single key. Users can simply press their fingerprint or enter a password to unlock, meeting their needs and improving both convenience and security.
