Description

Technical Field

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

[0002] In related technologies, smart locks are mainly structured as either an integrated lock body or a separate lock body. An integrated lock body is a single, replaceable lock body comprising a user information collection sensor, a data transmission device, an electronic lock cylinder, and a battery. However, this type of integrated lock body can only be adapted to certain types of doors, limiting its applicability. A separate smart lock, where the lock itself and the user information data collection are separate components, typically requires pre-embedded cables in the wall and reserved installation space, making installation complex. Converting existing locks into smart locks requires dismantling or modifying the original lock body and door, resulting in waste, high installation costs, and limited applicability.

[0027] Smart locks are modern locks that add intelligent functions to traditional locks, making them more convenient, secure, and intelligent to use. They are an important component of modern smart homes and a crucial gateway for the Internet of Things (IoT) connecting the virtual and real worlds. The biggest difference between smart locks and traditional locks is that smart locks can replace physical keys and unlock / lock doors via fingerprints, passwords, or mobile apps, eliminating the need for traditional mechanical keys. This is especially convenient when users forget or lose their keys. When integrated into a smart home system, smart locks can interact with other smart home devices. For example, when a smart lock detects a user's arrival home, it can automatically turn on lights and music; when it detects a user leaving home, it can automatically turn off lights and appliances.

[0028] Currently, smart locks are mostly available as accessories, often configured separately from the door. Smart locks typically exchange data via wireless networks, enabling the uploading of current data and the execution of remote commands. There are two main types of smart locks: one is an integrated replacement for the door's original lock, consisting of an outer, inner, and middle section; the other is a separate unit, including a wall-mounted interactive device for opening and locking the door. This device connects to the network, can identify the user, and can control the door's status remotely. It also includes an externally controllable door and lock body; this type of lock is often electromagnetic and lacks a physical mechanical lock cylinder.

[0029] Integrated door locks have the following drawbacks: First, retrofitting existing door locks requires removing the existing ordinary lock body, limiting the original lock configuration and resulting in wasted investment. Second, because door locks come in various specifications such as ordinary lock bodies, standard lock bodies, and large lock bodies, some older doors do not have the space to install smart lock bodies, leading to compatibility failures. Even for doors suitable for smart locks, installation may be impossible due to door type limitations, such as wrought iron doors, fence doors, double-lock doors, glass security doors, bullhead locks, hidden locks, alloy copper doors, sliding doors, and folding doors. Furthermore, requirements such as guide plate size, latch groove size on the door frame, door panel thickness, distance of the lock faceplate from the door edge, and lock body eccentricity can also prevent installation. Third, some doors are equipped with deadbolts, where the lock body is connected to the latch via a connecting device. When the lock body is locked, the latches at the top and bottom of the door extend vertically out of the door body and insert into the door frame. Because the distance between the latch and the lock body is relatively far, the deadbolt is usually only compatible with the original lock body and is generally incompatible with smart locks. Even if it can be hooked onto a smart lock, there are size mismatch issues, posing a risk of detachment. Once the lock body and deadbolt detach, the door will be completely locked from the inside and can only be removed by force. Fourthly, users can directly access the lock from the outside of the house, meaning they can physically break the lock, such as through electromagnetic attacks using a "black box" to force a circuit restart, thus posing a certain security risk.

[0030] Split-type door locks are generally powered by mains electricity, eliminating the need for regular power supply replacements and enabling remote control. Controlled by an external electromagnet, they minimize damage to existing doors and the need for component replacements. However, because the controller is typically mounted on a wall and the electromagnet needs to be fixed to the top of the door frame, high-quality infrastructure is required, usually necessitating pre-embedded cables and reserved installation locations within the wall. Furthermore, since the interaction device is located outside the door, the lock system can be physically intruded upon from the outside, posing a certain security risk.

[0031] In the current door lock market, despite the continuous advancement of smart door lock technology, most smart door locks require modification or replacement of the original door or lock body during installation. This not only increases the cost of modification but may also damage the original door structure.

[0032] Embodiments of the present invention, with reference to Figure 1 As shown, a smart door lock and a smart door lock system are provided.

[0033] According to one embodiment of the present invention, referring to Figure 1As shown, the smart door lock according to an embodiment of the present invention includes a door lock body 100, on which a guide wheel 110 is mounted; a mounting structure 200 disposed on the door lock body 100, the mounting structure 200 being adapted to mount the door lock body 100 to a door handle; when the door lock body 100 is mounted to the door handle, the guide wheel 110 is adapted to roll along the door body on which the door handle is mounted; a drive mechanism 300 including a drive member 310 and a circuit board 320, the circuit board 320 being adapted to control the drive member 310 to drive the guide wheel 110 to roll along the door body based on a received detection signal, so as to drive the door handle to rotate; and a detection sensor 400 electrically connected to the circuit board 320, adapted to send a detection signal to the circuit board 320.

[0034] It is understandable that during the installation of the smart lock or the modification and optimization of the original lock, the smart lock in this embodiment can be installed on the door handle. The lock body 100 is used to carry other functional components of the smart lock, and a guide wheel 110 is installed on the lock body 100. When the smart lock is installed on the door handle, the guide wheel 110 contacts the surface of the door and can roll along the surface of the door. Since the lock body 100 is fixed on the door handle, the guide wheel 110 can rotate the door handle when it moves, thereby realizing the unlocking and locking of the door handle's bolt.

[0035] With the door lock body 100 installed on the door handle, the guide wheel 110 will come into contact with the door body on which the door handle is installed. When the user needs to unlock or lock, the guide wheel 110 will roll along the surface of the door body, thereby driving the door handle to turn. This rolling motion design reduces friction, making the operation of the door lock easier and smoother.

[0036] In this embodiment, the number of guide wheels 110 can be one or more. In an optional implementation, the door lock body 100 is provided with multiple guide wheels 110. Multiple guide wheels 110 can ensure that the door lock body 100 and the door body form multi-point contact, thereby enhancing the stability of the door lock body 100 and reducing shaking and instability. Multiple guide wheels 110 can disperse friction, making it smoother during rolling and improving rotation efficiency. Due to the more uniform force distribution, multiple guide wheels 110 can reduce the wear of a single guide wheel 110 and extend its service life.

[0037] The mounting structure 200 in this embodiment can be specially designed to ensure that the door lock body 100 can be stably installed on the crossbar of the door handle. The mounting structure 200 can also ensure good contact and friction between the guide wheel 110 and the door body to achieve stable movement.

[0038] The drive mechanism 300 includes a drive component 310 (such as a motor) and a circuit board 320. The circuit board 320 receives signals sent by the detection sensor 400 and controls the action of the drive component 310 according to the signal content. The drive component 310 can be connected to the guide wheel 110 through a transmission mechanism, driving the guide wheel 110 to roll along the door body, thereby driving the door handle to rotate and realizing the unlocking or locking of the door body.

[0039] In this embodiment, the drive component 310 can be a high-torque motor. A high-torque motor has excellent torque output capability, providing sufficient force to overcome various resistances that the door handle may encounter during rotation, thereby driving the door handle to rotate. During this process, the torque output of the high-torque motor ensures that the door handle can quickly and accurately rotate to the designated position, realizing the unlocking or locking of the latch. Furthermore, because the torque output of the high-torque motor is stable and reliable, the door lock is less prone to failure or damage during long-term use, ensuring its durability.

[0040] In an alternative implementation, the motor can rotate in both forward and reverse directions. The door handle can be prevented from rotating by the reverse drive of the drive unit 310, thereby achieving the door locking function and improving the security performance of the door lock.

[0041] The detection sensor 400 is the sensing component of the smart lock, responsible for real-time monitoring of user operations or environmental signals. Detection sensors 400 come in various types, including but not limited to fingerprint sensors, keypads, and infrared sensors. These sensors are electrically connected to the circuit board 320, and when they detect a valid signal (such as successful fingerprint matching or correct password input), they send a corresponding detection signal to the circuit board 320.

[0042] Sensors 400 play a crucial role in smart locks. They not only ensure that the lock can be opened or closed only under correct operation, but also provide users with a more convenient and secure experience. For example, fingerprint sensors ensure that only authorized users can open the lock; keypads allow users to open the lock by entering the correct password; and infrared sensors enable automatic sensing and unlocking functions.

[0043] According to an embodiment of the present invention, the smart door lock includes: a door lock body 100, on which a guide wheel 110 is mounted; a mounting structure 200 disposed on the door lock body 100, adapted to mount the door lock body 100 to a door handle; when the door lock body 100 is mounted to the door handle, the guide wheel 110 is adapted to roll along the door body on which the door handle is mounted; a drive mechanism 300 including a drive member 310 and a circuit board 320, the circuit board 320 being adapted to control the drive member 310 to drive the guide wheel 110 to roll along the door body based on a received detection signal, thereby causing the door handle to rotate; and a detection sensor 400 electrically connected to the circuit board 320, adapted to send a detection signal to the circuit board 320. By fixing the door lock body 100 to the door handle and controlling the movement of the guide wheel 110 to drive the door lock body 100 to move, thereby causing the door handle to rotate, the smart door can be upgraded without modifying or replacing the original door body and lock body, with a wide range of adaptability and low modification cost.

[0044] According to one embodiment of the present invention, the detection sensor 400 is a fingerprint sensor, and the fingerprint sensor is separately disposed from the door lock body 100.

[0045] Understandably, in this embodiment, to enhance the convenience and flexibility of the smart lock, the fingerprint sensor and the lock body 100 can be configured as separate structures. This design allows the information collected by the fingerprint sensor to be remotely transmitted to the circuit board 320 in the lock body 100, enabling users to control the smart lock and drive the door handle from other locations in the room. This eliminates the need for users to go to the lock for authentication; they can simply use the fingerprint sensor from anywhere in the room, greatly improving ease of use.

[0046] In addition, because the fingerprint sensor is separate from the door lock body 100, it is difficult for attackers to directly target the door lock body 100 for brute-force cracking or technical unlocking, thereby increasing the security of the door lock.

[0047] In other embodiments, the fingerprint sensor can be installed in a suitable position on the door lock body 100. When the user uses the door handle normally, the thumb will naturally rest on the fingerprint sensor, the device will unlock, and the user can open the door normally.

[0048] According to one embodiment of the present invention, referring to Figure 1 As shown, the mounting structure 200 includes a strap 210 and an adjusting locking assembly 220. One end of the strap 210 is connected to the door lock body 100, and the other end is provided with a rack. The rack is adapted to engage and lock with the adjusting locking assembly 220 to adjust the length of the strap 210. The rack is designed to engage with the adjusting locking assembly 220 and adjust the length of the strap 210.

[0049] Understandably, in this embodiment, the strap 210 is made of a flexible and adjustable material. One end is firmly connected to the door lock body 100, ensuring that the door lock body 100 can be fixed to the door handle. The other end is equipped with a rack, the teeth of which engage with the adjusting locking assembly 220 to achieve precise length adjustment. The rack is a key component of the strap 210, and its teeth mesh with the gears of the adjusting locking assembly 220. By rotating the adjusting locking assembly 220, the user can easily increase or decrease the length of the strap 210 to accommodate door handles of different sizes.

[0050] In an alternative implementation, the adjusting locking assembly 220 may include a gear and an adjusting knob. The gear meshes with a rack, and when the user rotates the adjusting knob, the gear moves the rack, thereby changing the length of the strap 210. This design allows the user to make fine adjustments to ensure the door lock is securely installed on the door.

[0051] In some embodiments, the strap 210 is elastic, which can better secure the door lock body 100 to the door handle; According to one embodiment of the present invention, referring to Figure 1 As shown, the strap 210 includes a first strap 211 and a second strap 212. The first strap 211 is disposed on the top of the door lock body 100, and the second strap 212 is disposed on the side of the door lock body 100.

[0052] It is understood that in this embodiment, the strap 210 includes at least a first strap 211 and a second strap 212, which are responsible for securing the door lock to different parts of the door handle. The first strap 211 is located at the top of the door lock body 100 and is used to secure it to the pivot portion of the door handle; the second strap 212 is located on the side of the door lock body 100 and is used to secure it to the handle grip portion of the door handle. The first strap 211 and the second strap 212 work together to provide stable support and fixation. By securing them to the pivot portion and handle grip portion of the door handle respectively, the first strap 211 and the second strap 212 together ensure the stability and security of the door lock. This design can effectively prevent the door lock from shaking or falling off during use.

[0053] According to one embodiment of the present invention, the strap 210 is made of rubber; and / or, the guide wheel 110 is made of rubber.

[0054] In one alternative embodiment, the strap 210 is made of rubber. The rubber strap 210 has excellent elasticity and durability, allowing it to fit snugly against the door handle, providing stable support and fixation. The rubber material also has good anti-slip properties, effectively preventing the door lock from slipping or loosening during use. Furthermore, the rubber strap 210 is relatively easy to install and remove.

[0055] In one optional implementation, the guide wheel 110 is made of rubber. The rubber guide wheel 110 has a high coefficient of friction and elasticity, ensuring smooth and stable sliding of the door lock. The rubber material of the guide wheel 110 provides strong friction, which can drive the installed door handle to rotate, simulating the action of turning the handle to open the door, thereby retracting the original door lock tongue and opening the door. This design not only reduces friction between the door lock and the door, reducing wear, but also extends the lifespan of the door lock. Furthermore, the rubber guide wheel 110 effectively reduces noise, providing a quieter operating environment for the user.

[0056] In summary, the design of the rubber strap 210 and guide wheel 110 makes the door lock more stable during installation and use, reducing the risk of shaking and slipping. The rubber material has high durability and wear resistance, which can extend the service life of the door lock. It is easy to install and disassemble, and the noise is low.

[0057] According to one embodiment of the present invention, referring to Figure 1 As shown, the smart door lock also includes a gear reduction assembly 500, which is disposed between the drive member 310 and the guide wheel 110.

[0058] Understandably, in this embodiment, the main function of the gear reduction assembly 500 is to convert the high-speed, low-torque output of the drive component 310 into a low-speed, high-torque output through gear transmission. This ensures smooth door handle rotation even when the door lock encounters significant resistance, preventing jamming or inability to open due to insufficient torque. Furthermore, the gear reduction assembly 500 reduces wear and damage to the drive component 310, extending the door lock's lifespan.

[0059] The gear reduction assembly 500 typically consists of multiple gears that mesh with each other according to a certain transmission ratio. When the drive component 310 rotates, it drives one of the gears to rotate, which in turn causes another gear to rotate at a slower speed through the transmission action of the gears. In this way, the purpose of converting high-speed, low-torque into low-speed, high-torque can be achieved.

[0060] According to one embodiment of the present invention, referring to Figure 1 As shown, the smart lock also includes a rechargeable battery 600, which is connected to the drive mechanism 300 to power the drive unit 310 and the circuit board 320.

[0061] Understandably, in this embodiment, the smart lock has a built-in rechargeable battery 600. This built-in battery provides a continuous and stable power supply to the drive unit 310 and the circuit board 320, ensuring the normal operation of all lock functions. The drive unit 310 requires stable power to achieve fast and accurate movements. The built-in rechargeable battery 600 provides sufficient power to ensure the lock's opening and closing functions are normal, preventing malfunctions during sudden power outages or interruptions.

[0062] In one alternative implementation, the door lock body 100 is provided with a charging interface, through which the rechargeable battery 600 can be charged, so there is no need to worry about insufficient power affecting its use.

[0063] According to one embodiment of the present invention, the smart door lock is further provided with an inverter module, which is connected to the guide wheel 110 and the rechargeable battery 600. The inverter module is adapted to drive the guide wheel 110 to rotate to generate electrical energy when the user turns the door handle, and store the electrical energy in the rechargeable battery 600.

[0064] Understandably, in this embodiment, when the user turns the door handle, the guide wheel 110 rolls, generating mechanical energy. The inverter module's function is to convert this mechanical energy into electrical energy and store it in the built-in rechargeable battery 600. The inverter module operates based on energy conversion and storage technology. Specifically, when the user turns the door handle, the mechanical energy generated by the rolling of the guide wheel 110 is captured by the inverter module and converted into electrical energy through an internal conversion mechanism. This electrical energy is then efficiently stored in the rechargeable battery 600 for use by the door lock's drive unit 310 and circuit board 320.

[0065] The inverter module generates electrical energy by utilizing the mechanical energy produced when the user turns the door handle, thus achieving efficient energy utilization and saving, and reducing the energy consumption of the door lock. Through the conversion by the inverter module, mechanical energy that might otherwise be wasted is effectively utilized, improving energy efficiency. Because the inverter module can convert the mechanical energy generated when the user turns the door handle into electrical energy and store it in the battery, it reduces reliance on the battery, thereby extending battery life. Users do not need to frequently replace the door lock battery or find charging cables; simply using the door handle normally will charge the battery, greatly improving convenience.

[0066] According to one embodiment of the present invention, the smart door lock is provided with at least one of a control button, an LED light, and a buzzer.

[0067] As is understood, in this embodiment, the control button is one of the interactive elements on the smart lock. By pressing the control button, users can perform various operations, such as unlocking, locking, and setting a password. The control button is typically made of durable materials to ensure it is not easily damaged during prolonged use.

[0068] LED lights play multiple roles in smart door locks. First, they can function as indicator lights, displaying the lock's current status, such as unlocked or locked. This intuitive display allows users to easily understand the lock's condition. Second, LED lights can also be used for nighttime illumination, making it easier for users to operate the lock in low-light conditions. Furthermore, smart door locks can utilize LED lights to change colors to indicate different operating states or provide informational messages.

[0069] A buzzer is a device in a smart door lock used to provide audible alerts. When a user performs certain actions, such as successfully unlocking the door or receiving an incorrect password, the buzzer will emit a corresponding audible alert to inform the user of the result.

[0070] According to one embodiment of the present invention, the smart door lock is equipped with a vibration sensor and a sound sensor, which are adapted to send signals to a circuit board 320 based on the detected vibration signals and sound wave signals, so that the circuit board 320 sends out warning information.

[0071] As is understood, in this embodiment, the vibration sensor is a device capable of detecting the vibration of an object and converting it into an electrical signal. In a smart door lock, the vibration sensor is installed in a critical part of the lock. When the lock is subjected to abnormal vibrations (such as prying or impact), the vibration sensor quickly captures these vibration signals and converts them into electrical signals. These electrical signals are then transmitted to the circuit board 320, where the processor analyzes and judges them. If the processor determines that these vibration signals are abnormal (i.e., there may be unsafe behaviors such as prying or impact), it immediately triggers the alarm system and sends out warning information.

[0072] Acoustic sensors, such as microphones, are used to detect acoustic signals around the door lock, such as knocking sounds and lock-picking sounds. When abnormal acoustic signals are detected around the door lock, the microphone quickly captures these signals and converts them into electrical signals. Similarly, these electrical signals are transmitted to the processor on circuit board 320 for analysis and judgment. If the processor determines that these acoustic signals are abnormal (i.e., there may be unsafe behavior such as lock picking or impact), it will also trigger the alarm system and send out warning information.

[0073] In some implementations, the smart lock immediately activates a buzzer to sound an alarm when the microphone or vibration sensor detects an anomaly. The buzzer emits a high-decibel alarm to attract the attention of those nearby and deter potential intruders. In addition to local alarms, the smart lock also transmits alarm information to the user's mobile phone or other designated devices via the internet. Alarm information typically includes detailed information such as the lock's real-time status, the time and location of the anomaly. Upon receiving the alarm, the user can react quickly, such as contacting property management or calling the police.

[0074] Microphones and vibration sensors can detect changes in the external environment in real time, ensuring a rapid response in case of abnormalities. The smart lock uses a combination of buzzer alarms and internet alarm information transmission to ensure that alarm information is delivered to users promptly and accurately. Through the internet alarm information transmission function, users can check the real-time status and security of the lock anytime, anywhere, enabling remote monitoring and management.

[0075] In one optional implementation, the smart lock operates as follows: the lock body 100 is wrapped around the inner door handle of the room by a strap 210, and the lock body 100 is firmly fixed to the door handle by an adjusting locking assembly 220 fixed to the lock body 100. The bottom of the lock body 100 may have an installation groove, and a high-friction rubber guide wheel 110 is installed thereon. The guide wheel 110 can be driven by a high-torque motor, and the torque is amplified by a reduction gear assembly. Since the lock body 100 is firmly installed to the door handle, the guide wheel 110 moves along the door panel, causing the door handle to rotate, thereby retracting the latch and allowing the door to be pushed open from the outside. The smart lock achieves its intended functions through a circuit board 320, including remote control of unlocking and unlocking; passive generation of electricity through the motor's rotation, storing electrical energy in a built-in rechargeable battery 600; control of the motor's forward and reverse rotation; simple control functions via control buttons on the device; and detection via a built-in sensor when the door is forcibly broken into, sending an alarm message via the internet. When a user uses the door handle normally, their thumb will naturally rest on the fingerprint sensor, the device unlocks, the motor cancels the reverse torque, allowing the user to rotate the door handle normally from inside the room to unlock.

[0076] Smart door locks can be equipped with high-torque motors, and the torque can be further amplified through a reduction gear assembly. Therefore, the locking function can be set so that when the door handle is detected to be rotating with an unlocking tendency, the gears rotate in the opposite direction to the unlocking direction, thus preventing the door handle from turning and locking the door. When the user turns the door from the inside, they can unlock it using a fingerprint sensor located at the thumb. The motor then cancels the reverse torque, allowing the user to rotate the door handle normally, thus unlocking and locking the door.

[0077] According to a second aspect of the present invention, an intelligent door lock system is provided, comprising: a door body, with door handles installed on both sides of the door body; and an intelligent door lock according to any of the above embodiments, wherein the intelligent door lock is installed on the door handles inside the door body.

[0078] This embodiment of the smart door lock does not require modification of the existing door or lock body; instead, it is directly installed on the existing door handle. Compared to existing installation methods, this proposal eliminates the need to remove the original door lock, avoiding wasted investment and eliminating concerns about incompatibility of the deadbolt or issues like hook detachment and deadbolt locking. It also has no requirements regarding the size of the guide plate, the size of the lock tongue groove on the door frame, the door panel thickness, the distance between the lock panel and the door edge, or the lock body's eccentricity. This significantly expands the range of compatible door types. Furthermore, this smart door lock is installed on the inside of the room, with no physical exposure on the outside of the door. This fundamentally eliminates the possibility of external physical intrusion, greatly improving security. It also features a simple structure, low cost, and ease of production.

[0079] According to one embodiment of the present invention, the door body is provided with a guide groove, the guide wheel 110 is provided with a guide groove, and the guide wheel 110 is adapted to move along the guide groove.

[0080] It is understood that, in this embodiment, a guide groove is provided on the door body. The design of the guide groove takes into account the movement trajectory and installation position of the door handle to ensure the stability and smoothness of the door handle during movement, effectively avoiding shaking or deviation, and improving the user experience.

[0081] It is understood that if the smart door lock has the beneficial effects of the above embodiments, then the smart door lock system will have the beneficial effects of the above embodiments accordingly. The specific implementation method can be referred to the above embodiments, and this application will not repeat it.

[0082] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the protection scope of the present invention.
