Description

Technical Field

[0001] This application relates to the field of door lock technology, specifically to the field of intelligent door lock system technology. Background Technology

[0002] In modern office environments, with increasing awareness of information protection and technological advancements, the demands for security and privacy in office spaces are rising. Especially in areas handling sensitive or confidential information, effectively isolating specific personnel from non-confidential areas while maintaining openness and collaboration throughout the office environment has become a crucial challenge.

[0003] While traditional mechanical door locks provide basic physical isolation, they fall short in terms of flexibility, security, and user experience. This is especially true in large offices with confidential work areas requiring frequent access, where they fail to meet modern office needs in terms of quiet operation and ease of opening and closing. Summary of the Invention

[0004] To address the aforementioned issues, this application proposes an intelligent door lock system. By integrating intelligent control technology and using a motor as the drive for opening and closing the door lock, it leverages Bluetooth technology to allow users to open and close the door lock via a password input keypad and mobile phone, providing a more efficient, secure, and quiet door lock solution for confidential work areas.

[0005] To achieve the above objectives, the present application adopts the following technical solution:

[0006] A smart door lock system includes a door lock that is opened and closed by a motor, the door lock having a clearance zone isolated from the motor, and the clearance zone having a motor controller;

[0007] It also includes a microcontroller for controlling the motor controller and a password input keyboard for sending control signals to the microcontroller;

[0008] It also includes a first near-field communication device that can receive control signals from the control terminal and sense nearby mobile phone signals and feed them back to the control terminal. The first near-field communication device is integrated into the microcontroller.

[0009] This application significantly improves the quietness of door lock operation by using a motor-driven door lock switch and setting up a clearance zone isolated from the motor for installing the motor controller, thus avoiding the noise generated when opening and closing traditional mechanical door locks.

[0010] Furthermore, the system integrates a microcontroller and a keypad, allowing users to open and close the door by entering a password and using the control terminal. This is both convenient and secure, preventing the risk of lost or stolen keys. Simultaneously, the near-field communication device can sense nearby mobile phone signals and relay them to the control terminal, effectively managing the access rights of personnel working near confidential areas. This is particularly suitable for setting up localized confidential areas within large office spaces, balancing confidentiality with open collaboration.

[0011] In some possible implementations, the door lock includes a base, a mounting cover for securing the motor to the base, an outer casing, and a lock cylinder, the mounting cover abutting the inside of the clearance area.

[0012] In this way, a clearance space is formed on the one-piece molded bottom shell to install the motor controller, which can effectively insulate sound while solving the heat dissipation problem of the motor controller.

[0013] In some possible implementations, the bottom shell has heat dissipation pits on the outer periphery of the air-retaining area.

[0014] In some possible implementations, the clearance area of ​​the bottom shell is provided with ventilation slots to further improve the heat dissipation effect of the motor controller.

[0015] In some preferred embodiments, the ventilation slot and the lock head are on opposite sides of the door lock.

[0016] In some possible implementations, a second near-field communication device is also included, which can be remotely equipped with a password input keyboard, and is located in the sheltered area.

[0017] In some preferred embodiments, the first communication device and / or the second near-field communication device is a Bluetooth device.

[0018] In some possible implementations, the motor controller and the second near-field communication device are housed in the fixed cover, allowing maintenance to be performed without disassembling the entire door lock; that is, only the fixed cover needs to be removed.

[0023] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:

[0024] In modern office environments, setting up secure work areas is a common practice. However, these areas often require frequent access, especially in large offices where employees may need to move frequently between secure and non-secure areas to facilitate communication and collaboration within teams. In such situations, traditional door lock systems often struggle to simultaneously meet the dual requirements of security and convenience.

[0025] Confidential work areas must be accessible only to authorized personnel to prevent the leakage of sensitive information. Traditional mechanical locks pose a high security risk because keys are easily copied. Furthermore, they are inconvenient for employees to access frequently.

[0026] In contrast, smart locks can authenticate identities through passwords, fingerprints, and facial recognition, significantly improving security. However, they also have drawbacks such as high installation costs and inconvenient maintenance. Therefore, setting up secure areas in large office areas is primarily to enhance awareness of confidentiality, rather than emphasizing rigid mechanical isolation. Furthermore, rigid isolation can also negatively impact communication and collaboration efficiency.

[0027] Therefore, different access permissions can be set for employees at different levels, and these permissions can be flexibly set and adjusted to ensure confidentiality while maintaining smooth communication. Personnel movement is only required to be within a controllable range.

[0028] This is also what this application aims to address: the need for a segmented approach that balances confidentiality and smooth communication within the premise of setting up local confidential areas in a large office space.

[0029] It should be noted that the terms "left," "right," "inner," and "outer" used in the following description refer to the directions shown in the attached diagram, especially "inner," which refers to the direction in which the door lock is installed and fixed.

[0030] Please refer to Figures 1 to 4 This application discloses an intelligent door lock system, including a door lock 1, which can be opened and closed by a motor 11. Please refer to [reference needed] for details. Figure 4 The door lock 1 includes a base shell 12, which can house a motor 11. The motor 11 is powered by a built-in storage battery 13. (Please refer to the reference.) Figure 2 The lock head 14 is driven by the motor 11 to unlock, and its reset method can be spring reset, which is a common technical means in the industry and will not be described in detail.

[0031] As a fixing device for the motor 11, a fixing cover 15 is provided on the outside of the bottom shell 12 to fasten the motor 11 to the bottom shell 12, and an outer shell 16 is provided on the outside of the fixing cover 15. For details of the bottom shell 12, please refer to [reference needed]. Figure 2 and Figure 3 The bottom shell 12 is provided with a clearance area 121 that is separated from the motor 11. The clearance area 121 is integrally formed on the bottom shell 12, and the inner side of the clearance area 121 abuts against the fixing cover 15.

[0032] Thus, a clearance space for installing accessories is formed between the clearance area 121 and the fixed cover 15. Furthermore, because this clearance space is not located in the same area as the motor 11, it also provides effective sound insulation for the entire door lock 1. Installing the motor controller 2 in this space will not be affected by the heat dissipation of the cavity containing the motor 11.

[0033] Specifically, by clicking the controller 2 on the fixed cover 15, maintenance can be performed without disassembling the entire door lock 1; that is, only the fixed cover 15 needs to be removed.

[0034] The intelligent door lock system of this application also includes a microcontroller 3 for controlling the motor controller 2. The motor controller 2 is used to control the operating state of the motor 11, including starting, stopping, speed adjustment, and direction control. It receives instructions from the microcontroller 3, precisely drives the motor 11 to perform corresponding actions, and provides feedback on the operating state of the motor 11.

[0035] The Microcontroller Unit (MCU) can handle password input processing, near-field communication control, remote control, status monitoring and feedback, ensuring the efficient, reliable and secure operation of the smart door lock system. It plays an important role, especially in office environments where frequent entry and exit are required and quiet operation is demanded.

[0036] As an input device for unlocking, a keypad 4 can be used to send control signals to the microcontroller 3, allowing the door lock 1 to be unlocked by entering a password. Furthermore, a first near-field communication device can be integrated into the microcontroller 3, enabling the microcontroller 3 to receive control signals from the control terminal 5 and unlock the door lock 1 accordingly.

[0037] The system integrates a microcontroller 3 and a password input keypad 4. Users can open and close the door lock by entering a password and unlocking it through the control terminal 51. This is convenient, fast, and secure, avoiding the risk of lost or stolen keys.

[0038] The first near-field communication device can be either NFC or Bluetooth, preferably Bluetooth. The control terminal 5 can be a computer, mobile phone, tablet, etc. The first near-field communication device can sense mobile phone signals near the door lock 1 and feed them back to the control terminal 5, that is, it feeds back the access control request from the mobile phone signal to the control terminal 5, which can be remotely authorized. In this way, flexible setting and adjustment of access permissions can be achieved.

[0039] Please refer to Figure 3 Since the inner side of the bottom shell 12, which is the part that abuts against the mounting body, needs to focus on heat dissipation, a heat dissipation pit 122 is provided on the outer periphery of the clearance area 121 of the bottom shell 12, and a ventilation slot 123 is provided on the outer periphery of the bottom shell 12 at the position where it connects to the clearance area 121, which further improves the heat dissipation effect of the motor controller 2.

[0040] Further, please refer to Figure 2 The ventilation slot 123 and the lock head 14 are located on the left and right sides of the door lock 1, respectively. When the door is closed, the ventilation slot 123 can also play a role in ventilation and heat dissipation.

[0041] Please continue to refer to this. Figure 1 and Figure 2 In some other embodiments, a second near-field communication device 21 is added to the airspace 12, which is preferably a Bluetooth device. The password input keyboard 4 can be remotely installed through the second near-field communication device 21.

[0042] As stated above, this case protects an intelligent door lock system, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
