Description

Technical Field

[0001] This utility model relates to the field of door lock technology, and in particular to an intelligent door lock structure. Background Technology

[0002] Smart door locks currently on the market generally include smart password unlocking, fingerprint unlocking, and mechanical key unlocking. The keyhole is usually not protected or has a protective cover to prevent dust or water from entering or debris from clogging it. Most existing protective covers use a snap-on method to block the keyhole.

[0003] Chinese Patent CN220036375U discloses a smart door lock protective structure and a smart door lock, including a base, a top cover, a limiting member, and an elastic member. The base has a fixing groove on one side and a rotating groove on the other side. The inner wall of the rotating groove has a placement groove. The top cover has a fixing buckle on one side and a rotating block with a rotating shaft on the other side. The limiting member is rotatably installed inside the placement groove, and the limiting member has a sliding groove inside. The rotating shaft is rotatably connected inside the sliding groove. By the buckle engaging with the fixing groove and the elastic member squeezing the limiting member, the friction between the sliding groove and the rotating shaft inside the limiting member is increased, thus preventing the top cover from becoming loose, causing the fixing buckle to disengage from the fixing groove, the top cover to detach from the base, and the lock hole to be exposed and damaged.

[0004] However, the aforementioned publicly available solutions have the following shortcomings: the existing smart door lock structure cannot alert surrounding users and homeowners when the lock is pried open by illegal personnel, thus making it impossible to take protective measures. In addition, the door lock usually only has one lock, which is not very effective and can be easily pried open, affecting the safety of users' lives and property. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that it cannot automatically alarm when the lock is pried open and cannot provide multiple locking protections for the door, and to propose an intelligent door lock structure.

[0006] The technical solution of this utility model is as follows: an intelligent door lock structure, including a door panel; and further comprising:

[0007] The double protection mechanism is located on the side of the door panel and is used for double locking when the door is locked.

[0008] Anti-pry lock mechanism: The anti-pry lock mechanism is located on the side of the double protection mechanism away from the door panel, and is used to automatically alarm when the lock is pried open;

[0009] In addition, there is a smart lock cylinder, which is located on the side of the door panel. An alarm is integrated inside the smart lock cylinder, and an infrared receiver is located on the side of the smart lock cylinder. The infrared receiver is used to receive infrared rays. If no infrared rays are received for a continuous period of time, it will control the alarm to be activated to alert the homeowner of any abnormal situation at the door.

[0010] Preferably, the smart lock cylinder has a lock frame on its side, a lock hole one on the lock frame, and a lock hole two below the lock hole one.

[0011] Preferably, it also includes protective components, which include a protective box, a protective plate, and an electromagnet;

[0013] Preferably, the dual protection mechanism includes a locking component and a reinforcement component;

[0014] The locking assembly is located inside the smart lock cylinder and in the upper part, and is used to connect and lock the smart lock cylinder and the lock frame together;

[0015] The reinforcement component is located inside the smart lock cylinder and in the lower half, and is used for a double connection after the locking component is locked.

[0016] Preferably, the locking assembly includes a lock head, a push rod, a fixing plate, and a spring.

[0017] The fixing plate is located inside the smart lock cylinder, the top rod is slidably located inside the fixing plate, the second spring is located outside the top rod, and the first lock head is located at the end of the top rod.

[0018] Preferably, the reinforcing components include a trapezoidal block, a second telescopic rod, a third spring, and a insert.

[0019] Telescopic rod 2 is located inside the smart lock cylinder, spring 3 is located outside the telescopic rod 2, trapezoidal block is located at the end of telescopic rod 2 away from the smart lock cylinder, insert is located at the bottom of trapezoidal block, lock head 2 is engaged on the outside of insert, lock head 2 is slidably connected to the outside of lock head 2 and the inside of smart lock cylinder, telescopic rod 3 is located at the end of lock head 2, and spring 4 is located on the outside of telescopic rod 3.

[0020] Preferably, the anti-pry lock mechanism includes a connecting plate, a telescopic rod, a spring, and a break plate;

[0021] The connecting plate is located on the side of the smart lock cylinder, the telescopic rod is located on the connecting plate and is symmetrically arranged on the upper and lower sides, the spring is located on the outside of the telescopic rod, the break plate is located on the door panel, and the infrared transmitter is located on the side of the lock frame.

[0022] Compared with the prior art, the present invention has the following beneficial technical effects:

[0023] 1. By using an electromagnet and a protective plate, when the smart door lock is in normal operation, the electromagnet attracts the protective plate to cover the keyhole, making the door more aesthetically pleasing and neat. At the same time, it is difficult for people unfamiliar with the door structure to find the keyhole, thus improving the anti-theft effect. When the door malfunctions and is powered off, the electromagnet releases the protective plate, exposing the keyhole, allowing users to directly open the door mechanically, making it more convenient.

[0024] 2. With the dual protection mechanism, after the first lock head is inserted into the first lock hole, it causes the bolt to disengage from the second lock head, thereby causing the fourth spring to drive the second lock head into the second lock hole for multiple locking. This eliminates the need for additional user operation, and physical reinforcement and system security are completed instantly when the door is closed. It also reduces the insertion space for tools such as crowbars and cards, making traditional lock picking methods difficult to implement, thus enhancing the door's protective effect and greatly improving user security, making users feel more at ease when living there.

[0025] 3. With the anti-pry mechanism, when the smart lock cylinder is pried open, the fracture plate will break, preventing the infrared receiver from receiving the infrared transmitter's rays and triggering an alarm to alert the user. This directly deters intruders and instantly attracts the attention of those around, creating social supervision pressure. At the same time, the system automatically completes the alarm process without requiring manual triggering by the user, making it especially suitable for the elderly, children, and other groups with operational difficulties.

Detailed Implementation

[0031] Example 1

[0032] like Figures 1-4 As shown, the present invention proposes an intelligent door lock structure, including a door panel 1, a double protection mechanism, an anti-pry lock mechanism, and an intelligent lock cylinder 305;

[0033] A double protection mechanism is located on the side of door panel 1 for double locking when the door is locked;

[0034] The anti-pry lock mechanism is located on the side of the double protection mechanism away from the door panel 1, and is used to automatically alarm when the lock is pried open;

[0035] The smart lock cylinder 305 is located on the side of the door panel 1. An alarm is integrated inside the smart lock cylinder 305. An infrared receiver 406 is located on the side of the smart lock cylinder 305. The infrared receiver 406 is used to receive infrared rays. After continuously not receiving infrared rays, it will control the alarm to start and sound an alarm, thereby reminding the homeowner of the abnormal situation of the door.

[0036] The smart lock cylinder 305 has a lock frame 201 on its side, a lock hole 202 on the lock frame 201, and a lock hole 203 below the lock hole 202. The smart lock cylinder 305 and the lock frame 201 are directly opposite each other.

[0037] The protective components include a protective box 301, a protective plate 303, and an electromagnet 302. The protective box 301 is located on the side of the smart lock cylinder 305, the electromagnet 302 is located on the top of the protective box 301, and the protective plate 303 is slidably located inside the protective box 301. The smart lock cylinder 305 has an unlocking hole 304. The smart lock is always powered during use. When powered, the electromagnet 302 generates attraction. The protective plate 303 is made of a magnetic plate. The electromagnet 302 attracts the protective plate 303 downwards, thus blocking the lock hole. At this time, the door is opened mainly by the smart unlocking method. When the smart lock is damaged, the electromagnet 302 is de-energized, thus losing its magnetic force. The protective plate 303 slides to the bottom inside the protective box 301, thereby exposing the lock hole for mechanical unlocking.

[0038] The dual protection mechanism includes a locking component and a reinforcing component; the locking component is located inside the smart lock cylinder 305 and in the upper part, and is used to connect and lock the smart lock cylinder 305 and the lock frame 201 together; the reinforcing component is located inside the smart lock cylinder 305 and in the lower part, and is used to make a double connection after the locking component is locked. The locking assembly includes a lock head 306, a push rod 307, a fixing plate 310, and a spring 308. The fixing plate 310 is located inside the smart lock cylinder 305, the push rod 307 is slidably located inside the fixing plate 310, the spring 308 is located outside the push rod 307, and the lock head 306 is located at the end of the push rod 307. The lock head 306 is trapezoidal in shape. When the door is closed, the inclined surface of the lock head 306 contacts the lock frame 201 and slides inside the lock. After the lock head 306 has slid completely into the smart lock cylinder 305, the lock hole 202 and the smart lock cylinder 305 are completely fitted together. At this time, the lock head 306 rebounds under the action of the spring 308 and is locked into the lock hole 202. The reinforcing components include a trapezoidal block 309, a second telescopic rod 311, a third spring 312, and a insert 313. The second telescopic rod 311 is located inside the smart lock cylinder 305, the third spring 312 is located outside the second telescopic rod 311, the trapezoidal block 309 is located at the end of the second telescopic rod 311 away from the smart lock cylinder 305, and the insert 313 is located at the bottom of the trapezoidal block 309. The inclined surface of the trapezoidal block 309 faces the end of the top rod 307. When the top rod 307 moves, it presses the trapezoidal block 309 through the inclined surface. The outer side of the insert 313 is engaged with a second lock head 314. The outer side of the second lock head 314 is slidably connected to the inner side of the smart lock cylinder 305. The end of the second lock head 314 is provided with a third telescopic rod 315. A spring 316 is provided on the side. The end of the telescopic rod 315 away from the lock head 314 is connected to the inside of the smart lock cylinder 305. When the door is open, the insert 313 is stuck in the notch of the lock head 314, thus fixing the lock head 314 inside the smart lock cylinder 305. When the door is closed, the top rod 307 drives the trapezoidal block 309 to move. The trapezoidal block 309 drives the insert 313 to move outward, thus disengaging from the lock head 314. Under the action of the spring 316, the lock head 314 is inserted into the lock hole 203 for double connection. When unlocking, the lock head 314 is controlled to retract into the smart lock cylinder 305. When the notch moves to the insert 313, the insert 313 is inserted into the lock head 314 for fixation under the action of the spring 312.

[0039] Example 2

[0040] like Figures 2-3 As shown, this utility model proposes an intelligent door lock structure. Compared with Embodiment 1, this embodiment details the structure of the anti-pry lock mechanism.

[0041] The anti-pry lock mechanism includes a connecting plate 401, a telescopic rod 402, a spring 403, and a fracture plate 404. The connecting plate 401 is located on the side of the smart lock cylinder 305, the telescopic rod 402 is located on the connecting plate 401 and is symmetrically arranged on the upper and lower sides, the spring 403 is located on the outer side of the telescopic rod 402, and the fracture plate 404 is located on the door panel 1. The fracture plate 404 and the connecting plate 401 are in contact with each other on the upper and lower sides. The fracture plate 404 is made of brittle material and is prone to breakage. An infrared transmitter 405 is located on the side of the lock frame 201. When the smart lock cylinder 305 is pried, the force acts on the fracture plate 404. After the fracture plate 404 breaks, the smart lock cylinder 305 shakes, causing the rays emitted by the infrared transmitter 405 to never reach the infrared receiver 406 directly. This causes the infrared receiver 406 to control the alarm inside the smart lock cylinder 305 to sound an alarm.

[0042] In summary, when this utility model is in use, in the open state, the insert 313 is engaged at the notch of the second lock head 314, thus fixing the second lock head 314 inside the smart lock cylinder 305. When the door is closed, the first lock head 306, under the action of the lock frame 201, drives the top rod 307 to slide, thereby the top rod 307 drives the trapezoidal block 309 to move. The trapezoidal block 309 drives the insert 313 to move outward, thus disengaging from the second lock head 314. The second lock head 314, under the action of the fourth spring 316, engages into the second lock hole 203 for a double connection. When unlocking, the second lock head 314 is controlled to retract into the smart lock cylinder 305. When the notch moves to the insert 313, the insert 313, under the action of the third spring 312, engages into the second lock head 314 for fixation. After sliding completely into the smart lock cylinder 305, the first lock hole 202 and the smart lock cylinder 305 are completely fitted together. Together, the lock head 306 rebounds under the action of the spring 308 and locks into the keyhole 202, achieving double locking. When the smart lock is pried, the force acts on the fracture plate 404. After the fracture plate 404 breaks, the smart lock cylinder 305 shakes, causing the rays emitted by the infrared transmitter 405 to never reach the infrared receiver 406. As a result, the infrared receiver 406 controls the alarm in the smart lock cylinder 305 to sound an alarm. The smart lock is always powered during use. When powered, the electromagnet 302 generates attraction. The protective plate 303 is made of magnetic plate. The electromagnet 302 attracts the protective plate 303 to the bottom, thus blocking the keyhole. When the smart lock is damaged, the electromagnet 302 is de-energized, thus losing its magnetic force. The protective plate 303 slides to the bottom of the protective box 301, exposing the keyhole.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
