Description

Technical Field

[0001] The present invention relates to the technical field of door locks, and in particular to an intelligent anti-theft door lock. Background Art

[0002] With the continuous development of modern technology, daily necessities are constantly combined with modern technology, and the forms of door locks are becoming more intelligent and diversified. The most core concerns in the field of door locks are: door lock safety, stability and user experience.

[0003] Existing smart door locks usually have the following problems: 1. When the user performs unconventional operations on the clutch installed in the fingerprint door lock on the market, such as long-term pressing of the fingerprint chip or frequent unlocking in a short period of time, the motor is very likely to be in a load state after receiving the command and running for a long time, which seriously reduces the service life of the motor; 2. The anti-theft performance is poor. Due to problems with the processing accuracy of some smart door locks, there is a small gap between the lock body and the door body during the installation process. Criminals take advantage of the gap to violently unlock the door lock and commit theft; 3. In order to save production costs, some Smart door locks are made of plastic, which makes the mechanical durability of the door locks low, and the door locks have low performance in resisting electromagnetic interference. Criminals can use Tesla coils to interfere with the door locks to unlock and steal; 4. Users cannot get feedback information quickly when unlocking the smart locks, which may lead to multiple openings or other misoperations of the door locks, which may easily cause the control system inside the device to fail; 5. Some smart door locks are equipped with feedback prompt devices, but the feedback prompt volume is high.

[0042] The present invention provides an intelligent anti-theft door lock, which is installed on a door body to prevent unauthorized users from opening the door lock.

[0043] In one embodiment of the present invention, Figures 1 to 11 As shown, the intelligent anti-theft door lock, an intelligent anti-theft door lock, includes an outer handle mechanism 1, an inner handle mechanism 2 and a lock body mechanism 3, and is characterized in that:

[0044] The lock body mechanism 3 includes a first lock body device 31, a second lock body device 32, a bolt device 33 and a transmission rod 34. The outer handle mechanism 1 passes through the first lock body device 31. One end of the transmission rod 34 passes through the first lock body device 31 and is connected to the outer handle mechanism 1. The other end passes through the second lock body device 32 and is connected to the inner handle mechanism 2. The middle part of the transmission rod 34 passes through the bolt device 33, and the end of the inner handle mechanism 2 passes through the second lock body device 32.

[0045] The first lock body device 31 includes a driving member 311 and a clutch assembly 312 . One end of the driving member 311 is embedded in the outer handle mechanism 1 , and the clutch assembly 312 is connected to the driving member 311 .

[0046] The first lock body device 31 and the second lock body device 32 are both provided with anti-theft covers 35 on their inner sides.

[0047] Specifically, Figure 1 to Figure 2 As shown, the outer handle mechanism 1 and the first lock body device 31 are installed on the outside of the door body, and the inner handle mechanism 2 and the second lock body device 32 are installed on the inside of the door body. The user can twist the outer handle mechanism 1 and the inner handle mechanism 2 to realize the rotation of the transmission rod 34 in the lock body device 3, and the lock tongue device 33 embedded in the door body is retracted inward due to the drive of the transmission rod 34, thereby realizing the opening of the door body. In addition, the outer handle mechanism 1 and the inner handle mechanism 2 are both independently arranged, and can be assembled on other face covers after being disassembled from the door body. The first lock body device 31 and the second lock body device 32 are used for the arrangement of other components inside them, and the installation area with the door body is larger, and the arrangement of the intelligent anti-theft door lock is more stable. The first lock body device 31 and the second lock body device 32 are also provided with pins to fix the two, so as to avoid the situation where the connection between the first lock body device 31, the second lock body 32 and the door body is destroyed due to excessive outward pulling force of the outer handle module 1 and the inner handle module 2. Since the first lock body device 31 is provided with a clutch assembly 312, it is necessary to input the correct authority so that the bolt device 33 will retract inwards and the door body will open when the driving member 311 and the clutch assembly 312 are in the correct position. The second lock body device 32 is not provided with a clutch, so the user can open the door body from the inside by turning the inner handle module 2.

[0048] The anti-theft cover 35 is provided to prevent the first lock device 31 from having a gap with the door body after being installed with the door body, so that an unauthorized user can use the gap to insert an unlocking tool to violently unlock the door lock and steal. The anti-theft cover 35 provided inside the first lock device 31 can form a closed cavity structure between the first lock device 31 and the door body, and between the second lock device 32 and the door body, for the purpose of anti-theft, and can also prevent dust in the air from entering the first lock device 31 and the second lock device 32, so that dust accumulation affects the normal use of other components.

[0049] Specifically, Figures 8 to 11 As shown, the clutch assembly 312 includes a clutch mother 3121, a clutch male 3122, a rotor 3123 and an unlocking column 3124, one end of the clutch male 3122 is connected to the transmission rod 34, and the other end thereof is connected to the clutch mother 3121, one end of the rotor 3123 is embedded in the clutch male 3122, and the other end thereof is connected to the driving member 311, and a gap is left between the rotor 3123 and the clutch male 3122, and the unlocking column 3124 is arranged in the gap between the clutch male 3122 and the rotor 3123; the surface of the rotor 3123 is symmetrically provided with a first recess 3125, and the surface of the clutch male 3122 is symmetrically provided with a second recess 3126.

[0050] In this embodiment, the driving member 311 is specifically a motor. When the door lock is in the locked state, the first recess 3125, the unlocking column 3124 and the second recess 3126 are in the same straight line. When the user twists the external handle mechanism 1 in this state, the clutch mother 3121 cannot drive the clutch male 3122 to work together due to the engagement of the unlocking column 3124, the first recess 3125 and the second recess 3126, thereby failing to drive the retraction and unlocking of the lock tongue device 33. When the motor receives the unlocking authority, the motor drives the rotor 3123 of the clutch assembly 312 to rotate 90°, and the unlocking column 3124 moves together with the rotor 3123 to move to the second recess 3126. At this time, the user rotates the external handle mechanism 1, and the clutch mother 3121 drives the unlocking column 3124 to work together, thereby driving the retraction of the lock tongue device 33 to unlock. During the actual operation, the driving member 311 will automatically reset 10 seconds after unlocking, and the driving member 311 will reverse 90 degrees to drive the rotor 3123 to reverse, so that the first recess 3125 and the second recess 3126 are aligned with the unlocking column 3124 again, and the clutch mother 3121 and the clutch male 3122 lose their linkage ability again, thereby returning to the locked door state.

[0051] Furthermore, a limiting post 3127 is provided at the end of the rotor 3123. In this way, the limiting post 3127 provided on the rotor 3123 can correspond to the opening at the front end of the clutch mother 3121, and the position of the rotor 3123 can be corrected. Due to the protruding setting of the limiting post 3127, the rotor 3123 is only allowed to rotate within the opening range at the front end of the clutch mother 3121, thereby ensuring the smoothness of the entire unlocking process and making the unlocking form more stable, avoiding the phenomenon that the user cannot unlock the lock when the user enters the correct authority but the rotor 3123 is out of the original position.

[0052] Furthermore, a rotating column 4 is provided at the end of the outer handle mechanism 1 and the inner handle mechanism 2, and the first lock body device 31 and the second lock body device 32 are both provided with a transmission plate 5 and a spring 6, and the transmission plate 5 and the spring 6 are clamped and arranged on the rotating column 4, and the spring 6 is located on the outside of the transmission plate 5; the transmission plate 5 is provided with a first limiting portion 51, and the spring 6 is provided with a second limiting portion 61, the first lock body device 31 is provided with a first surface cover 313, and the inner side of the first surface cover 313 is provided with a first protruding portion 3131, the second lock body device 32 is provided with a second surface cover 321, and the inner side of the second surface cover 321 is provided with a second protruding portion 3211, and the first limiting portion 51 and the second limiting portion 61 are both clamped and arranged with the first protruding portion 3131 and the second protruding portion 3211.

[0053] Specifically, the setting of the rotating column 4 is mainly to facilitate the user to rotate the outer handle mechanism 1 and the inner handle mechanism 2. When the outer handle mechanism 1 and the inner handle mechanism 2 are rotated clockwise, the transmission plate 5 and the spring 6 connected to the first lock body device 31 and the second lock body device 32 rotate at the same time, and the first cover 313 and the second cover 321 are fixed to the door body, so the first limit part 51, the second limit part 61 and the first protrusion 3131 and the second protrusion 3211 are disengaged to realize the opening of the door lock. When the user does not obtain the authority, the first limit part 51, the second limit part 61 and the first protrusion 3131 and the second protrusion 3211 are clamped, and the door body cannot be opened.

[0054] Furthermore, a through hole 11 is provided at the top of the external handle mechanism 1, and the external handle mechanism 1 is also provided with a fingerprint collection device 12, which is arranged in the external handle mechanism 1, and the fingerprint collection device 12 includes a fingerprint chip 121 and a main control board 122, the fingerprint chip 121 is embedded in the through hole 11, and the main control board 122 is arranged at the lower end of the fingerprint chip 121; the first lock body device 31 also includes a password component 314, and the password component 314 is arranged in the first lock body device 31, and the password component 314 includes a button 3141 and a password board 3142, the first surface cover 313 is provided with a mounting hole 3132, the button 3141 is embedded in the mounting hole 3132, and the password board 3142 is arranged at the bottom of the button 3141.

[0055] In this way, the smart anti-theft door lock can adopt two unlocking methods, including: fingerprint unlocking and password unlocking, and the fingerprint collection device 12 and the password component 314 are both independently set, respectively set in the external handle mechanism 1 and the first lock body device 31, both of which can realize the opening of the door body. When an electronic failure occurs in one of the unlocking devices, it will not cause the entire lock body to fail and the user will not be able to lock the door.

[0056] The fingerprint collection device 12 is mainly used to identify the user's fingerprint. After the fingerprint chip 121 identifies the correct fingerprint, it sends a command to the lock body mechanism 3 through the main control board 122, and the lock tongue device 33 retracts inward to open the door. The lock body device 3 can also be set to an open mode through the fingerprint unlocking method. When the user needs to enter the house frequently, in order to ensure the convenience of entry and exit and reduce the wear of the door lock, the lock tongue device 33 will rotate the drive member 311 90° after obtaining the correct opening authority. At this time, the clutch mother 3121 and the clutch male 3122 enter a linkage state. When the external handle mechanism 1 is rotated, the user keeps pressing the fingerprint for 10 seconds. When the motor is reset 90°, the unlocking column 3124 is in the second concave position 3126, and the unlocking column 3124 is locked. It is in the same straight line with the rotor 3123. Since the second recess 3126 is an arc-shaped setting, the stress acting on the unlocking column 3124 will squeeze the rotor 3123, causing the driving member 311 to be unable to drive the rotor 3123 when resetting. Thereafter, the door lock enters the open mode. When the user enters the fingerprint again, the main control board 122 sends permission to the driving member 311, and the door lock will release the open mode. The setting of the open mode avoids the situation where the motor is damaged due to excessive load caused by frequent operation of the door lock and misoperation.

[0057] The password assembly 314 is used for the user to input the password to open the door lock. When the correct password is entered at the button 3141, the password plate 3142 can transmit the instruction to the driving member 311, and the driving member 311 drives the entire clutch assembly 312 to rotate, thereby retracting the lock tongue device 33 and the door body can be opened.

[0058] Specifically, the outer handle mechanism 1 further includes a sound-generating portion 13 , and the sound-generating portion 13 is disposed at the bottom end of the outer handle mechanism 1 ; a sound outlet 14 is disposed at the bottom end of the outer handle mechanism 1 .

[0059] Through the setting of the sounding part 13, the user can be prompted for the opening of the intelligent anti-theft door lock. For fingerprint recognition and incorrect password input by abnormal users, the sounding part 13 voice broadcasts errors. And after continuous recognition and input errors, the door lock alarm will be automatically triggered, and the sounding part 13 transmits the alarm sound from the sound outlet 14, so as to deter illegal unlocking. In the case of an alarm, the user has three opportunities to enter the correct authority for the alarm to be released. If the input and recognition errors are continued, the door lock will enter the self-locking state, and the self-locking state will be maintained for 5 minutes. When the user returns at night, in order to maintain a quiet use environment, the user can press and hold the button 3141 for one second, after which the intelligent anti-theft door lock enters the silent mode. At this time, the user will not make any sound when operating the door lock, so as to prevent the operation sound of the door lock from being too loud and affecting other people's sleep. When the power supply of the door lock is at a low power level, the sounding part 13 will give a prompt that the power supply is too low, and the user can replace the power supply of the door lock, and at this time the user can also open the door lock 100 times.

[0060] Furthermore, if Figure 3 As shown, the external handle mechanism 1 further includes a light emitting device 15, and the light emitting device 15 is disposed at one end of the rotating column 4 close to the external handle mechanism 1;

[0061] The light emitting device 15 includes an aperture plate 151 and a light transmitting plate 152 . The light transmitting plate 152 is disposed at the connection between the outer handle mechanism 1 and the rotating column 4 . The aperture plate 151 is clamped and disposed at the end of the outer handle mechanism 1 .

[0062] In this way, the aperture plate 151 provided on the light-emitting device 15 can be used for feedback of light effects, and the user can interact with the door lock more intuitively. At this time, the lamp beads of the aperture plate 151 can transmit light through the light-transmitting sheet 152 provided at its front end, and the light-transmitting sheet 152 can make the light emission of the aperture plate 151 more concentrated. When the user obtains the unlocking authority, the green running light of the aperture plate 151 lights up; in the case of an incorrect unlocking, the red running light of the aperture plate 151 lights up, so that the user can judge whether the door lock has accurately read the fingerprint and entered the correct password.

[0063] Specifically, the top of the inner handle mechanism 2 is provided with a power supply installation position 21 for accommodating a power supply, and the end of the power supply installation position 21 is provided with a cover body 22. It can be understood that the battery can be installed in the power supply installation position 21 to provide energy for the intelligent anti-theft door lock and maintain the normal operation of the door lock. The power supply installation position 21 is arranged in the inner handle mechanism 2, which reduces the overall structure of the lock body and facilitates the replacement of the battery, which is replaced by twisting the cover body 22. Specifically, after removing the cover body 22, align the positive pole of the battery with the inner handle mechanism 2 to take positive power through the positive pole power taking spring and the positive pole power taking seat. Since the cover body 22 itself is conductive, the nature of the battery can be used to conduct negative conduction through the cover body 22. At this time, the entire lock is in a negative pole state, and the negative pole state of the entire lock is more conducive to the discharge of static electricity.

[0064] Furthermore, a charging port 16 is provided on the outer side of the first cover 313. With the provision of the charging port 16, when the user is away from home for a long time and the battery is out of power, the power supply of the door lock is not replaced in time, resulting in the door lock being unable to be opened normally. At this time, a power bank can be used to connect a data cable to the charging port 16 to charge the door lock, so that the user can open the door lock.

[0065] Furthermore, the outer handle mechanism 1 and the inner handle mechanism 2 are made of zinc alloy. Zinc alloy is an alloy composed of zinc and other elements. Common alloy elements include aluminum, copper, magnesium, cadmium, lead, titanium, etc. Zinc alloy has good mechanical durability and is easy to process in production. It can resist water vapor erosion and oxidation during use as a door lock material, and has good anti-electromagnetic field performance. It is a very effective shielding material in radio frequency interference, thereby resisting Tesla coils and other electromagnetic interference, and preventing door locks from being opened by criminals for theft.

[0066] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.

At this time, the user rotates the external handle mechanism, and the clutch mother drives the unlocking column to work together, thereby driving the retraction of the lock tongue device to unlock; in the actual operation process, the driving member will automatically reset 10 seconds after unlocking, and the driving member reverses 90° to drive the rotor to reverse, so that the first recess and the second recess are aligned with the unlocking column again, and the clutch mother and the clutch male lose the linkage ability again, thereby returning to the locked door state. The driving member reverses and drives the rotor to reverse; The surface of the rotor is symmetrically provided with first concave positions, and the surface of the clutch male is symmetrically provided with second concave positions.
