Description

Technical field

The invention relates to the field of locking devices, in particular door locks.

State of the art

With accelerated urbanization, there was a need to increase the security of the premises. The widespread use of electronic door locks that identify the user by fingerprint, because they exempt him from the restrictions imposed by the keys. However, due to the fact that typos can be falsified, the reliability of door locks is very doubtful. In addition, since an electronic door lock requires continuous power supply, the energy consumption of door locks is relatively large, and users often have to change batteries, which not only consumes power sources, but also pollutes the environment. Moreover, existing methods for disassembling and installing batteries in a locking device are very complex. To replace the batteries, it is usually necessary to remove the panel of the locking device and even need to disconnect the decorative overlay on the panel. After frequent disassembly and installation of the batteries, the screws or shrink discs on the panel wear out, which affects the use of the door lock. In addition, if the door cannot be opened due to insufficient battery of the door lock, the use of the door is seriously hindered, as a result of which the experience of use becomes negative.

The objective of the utility model is to create a door lock to reduce energy consumption, simplify dismantling and installation operations, and improve the user experience.

Below the present utility model is described in more detail with reference to the drawings and in combination with embodiments of the utility model.

In FIG. 1 shows a schematic structural diagram of a door lock in one embodiment of a utility model. As shown in FIG. 1, the door lock includes a locking mechanism 3, a power supply interface 4, a main control board 5, an environmental information collecting device 7, and a power management device 8.

In this embodiment of the utility model, the locking mechanism 3, the power supply interface 4, and the power management device 8 are connected to the main control board 5, and the environmental information collecting device 7 is connected to the power management device 8.

In this embodiment of the utility model, the configuration of the components of the door lock is as follows. The device 7 for collecting environmental information is intended to collect information about the environment surrounding the door lock and transmit environmental information to the power management device 8. The power management device 8 is designed to perform a matching operation according to environmental information and outputting a power mode consistent with environmental information to the main control board 5. The power supply interface 4 is intended to perform an operation related to a power supply mode consistent with environmental information according to a command to a power supply coming from the main control board 5.

In this embodiment of the utility model, when the user opens the door lock, the components of the door lock are operated as follows.

Firstly, the environmental information collecting device 7 collects information about the environment surrounding the door lock and transfers it to the power management device 8.

Further, the power management device 8 performs a matching operation according to the environmental information and provides a power mode consistent with the environmental information to the main control board 5.

The field of this power supply interface 4 performs an operation related to the power supply mode consistent with environmental information according to a command from the main control board 5.

Environmental information collected by the environmental information collecting device 7 may be signals from a capacitive sensor, from a resistive sensor, acoustic information, thermal radiation information, and light information. Depending on the different types of information to be collected, the environmental information collection device 7 may include various types of sensors (e.g., acoustic sensor, infrared sensor or photosensitive sensor, etc.) or switching devices (e.g., capacitive touch switch or resistive touch switch). In particular, information from a capacitive sensor can be collected using a capacitive touch switch. A capacitive touch switch can accurately detect the actual touch of a finger through a body of insulating material (glass, plastic or the like) with a thickness of more than 20 mm, thereby guaranteeing sensitivity, stability, reliability, etc. the products will not change due to changes in environmental conditions or long service life, and provide water resistance and good noise immunity. Similarly, information from a resistive sensor can be collected using a resistive sensor. It is understood that one of ordinary skill in the art may use other sensors to collect relevant environmental information, as appropriate.

In some embodiments of the utility model, the power management device 8 comprises a reference information storage unit 81, an environmental information comparison unit 82, and a power mode selection unit 83. The environmental information comparing module 82 is designed to compare the environmental information collected by the environmental information collecting device 7 with the environmental help information previously stored in the help information storage unit 81 and outputting the comparison result to the power supply mode selecting module 83 . The power supply mode selection module 83 is designed to select a power supply mode consistent with the result of the comparison and transfer the operation mode of the power supply to the main control board 5.

In some embodiments of the utility model, selecting a power mode consistent with environmental information according to the comparison result includes outputting a normal power mode (e.g., a power mode of all components, i.e., a power mode in which a standard rated voltage is applied to all door lock components), if it is revealed from the comparison result that the environment surrounding the door lock is dynamic; or the issuance of an energy-saving power mode, if the comparison revealed that the environment surrounding the door lock is static.

In particular, for example, an energy-saving power supply mode includes a power supply mode for a part of the components in which power is supplied to some components (for example, the environmental information collecting device 7 and the main control board 5) of the door lock. As another example, the power supply of some components is lowered relative to the rated voltage, and the power supply of other components is carried out by the rated voltage.

The device 8 power management can be performed, in particular, as follows.

For example, if a capacitive touch switch detects a touch of a user's finger, the environment is considered to be dynamic. This means that the user needs to open the lock, and for this reason the rated voltage is applied to the corresponding components of the door lock.

For example, if the sound intensity is less than 20 dB, it is considered that the medium is static, and for this reason there is currently no need to open the lock. There is no need to supply the rated voltage to the device 7 for collecting environmental information, so that only the operating voltage is supplied to the main control board 5. If the sound intensity is higher than 20 dB, it is considered that the environment is dynamic, which means that at the moment there is a need to open the lock, and for this reason the rated supply voltage is applied to the corresponding components of the door lock.

In another example, if the presence of thermal radiation from the human body is detected by an infrared sensor, it is considered that the environment is dynamic and someone is approaching a door lock. At the moment, there may be a need to open the lock, and then the rated supply voltage is applied to the corresponding components of the door lock.

In another example, if the power supply control device determines that the environment surrounding the door lock is static for a predetermined period of time, it is assumed that the user can be on vacation and a power mode is issued in which the entire door lock is de-energized. In this mode, the door lock cannot be used. Only after restarting the door lock can it return to normal operation. For example, a predefined time period may be 24 hours. Typically, the door lock of a home or business is opened at least once in 24 hours. Thus, if no operations are performed with the door lock within 24 hours, this means that the user using the door lock is on vacation. In this case, further supply of energy to the door lock will lead to a waste of energy. Of course, a predetermined period of time can also be flexibly adjusted according to need. For example, a predetermined period of time may be greater or less than the above value. In energy saving mode, the door lock can work in control mode and sleep mode. In the power off mode, the door lock may be in a deep sleep state. A specific power supply mode can be flexibly set depending on the current need.

In some embodiments of the present utility model, environmental reference information stored in module 81 may be as shown in Table 1.

Table 1

Sound Intensity Reference Chart Reference numerical sound intensity ranges (dB) Time (hour) Power mode ≤20 ≤24 Energy Saving Power Mode > 20 ≤24 Normal Power ≤20 > 24 Disconnected Power Mode

One skilled in the art will understand that an environmental reference table may contain reference tables of various environmental parameters, or reference information of various environmental parameters may be contained in a single table. If necessary, in particular, personalized settings can be made, and in this aspect the table of contents is not limited.

Thus, in the lock according to the utility model, the power supply mode can be flexibly adjusted in accordance with a change in the environment surrounding the door lock to efficiently power the door lock. As a result, electrical energy can be significantly saved and the frequency of replacement of the power source can be reduced. In addition, the user workload can be reduced, the service life of the door lock can be increased, and the user experience is improved.

In FIG. 2 is a schematic structural diagram of a door lock in another embodiment of the utility model. As shown in FIG. 2, the door lock contains the following components: front panel 1, rear panel 2, locking mechanism 3, power supply interface 4, main control board 5, finger vein pattern recognition device 6, environmental information collecting device 7, power management device 8, keyboard 9 for entering a password, a monitoring device 10, an event monitoring device 11, an alarm device 12, a wireless communication device 13, a mechanical keyhole 14 and contacts 15 of the electrodes (two electrodes, i.e., positive and -negative electrodes).

In this embodiment of the utility model, the number of functional components is increased compared to the embodiment shown in FIG. 1, so that the door lock has more functions. For brevity, the same or similar content to the embodiment shown in FIG. 1 is not repeated, and only components added to the components shown in FIG. 1: front panel 1, rear panel 2, finger vein pattern recognition device 6, a password input keypad 9, a control device 10, an event control device 11, an alarm device 12, a wireless communication device 13, a keyhole 14 and contacts 15 of the electrodes .

In this embodiment of the utility model, the placement and communication of the above added components may be as follows.

A finger vein pattern recognition device 6, a password input keyboard 9, a control device 10, an event control device 11, an alarm device 12, a wireless communication device 13 are connected to the main control board 5. The mechanical keyhole 14 is directly connected to the locking mechanism 3. The contacts 15 of the electrodes are directly connected to the power supply interface 4. A finger vein pattern recognition device 6, an environmental information collecting device 7, a password input keyboard 9, a control device 10, a mechanical keyhole 14 and electrode contacts 15 can be embedded in openings in the front panel 1 directly located anywhere on the front panel 1 or on the periphery of the front panel 1, etc. The power supply interface 4 can be integrated into a hole in the rear panel 2 directly located at any point on the rear panel 2 or on the periphery of the rear panel 2, and the like. An event monitoring device 11, an alarm device 12, and a wireless communication device 13 may be located between the front panel 1 and the rear panel 2. Specific locations are arbitrary.

In this embodiment of the utility model, the front panel 1 and the rear panel 2 of the door lock are made of zinc alloy. Zinc alloy is obtained by adding other elements to the base zinc. Commonly added alloy elements are aluminum, copper, magnesium, cadmium, lead, titanium and other elements that can form a low-temperature zinc alloy. Zinc alloy has a low melting point and good fluidity, suitable for fusion welding, brazing, plastic processing and is resistant to atmospheric corrosion. Residues of the zinc alloy can be reused and remelted. Naturally, a door lock can also be made from traditional copper, steel, iron and other materials. Door lock circuit elements may use electronic plastics and other materials.

In the present utility model, the configuration of the door lock components may be as follows.

The finger vein pattern recognition device 6 is designed to collect information about the pattern of the veins of the finger and send it to the main control board 5, so that the main control board 5 can carry out an identity check according to the information stored on it about the veins of the finger of the user. It is believed that an identity check is successful if the collected information about the pattern of the veins of the finger and the stored information about the pattern of the veins of the finger match. Additional details of this device are discussed below.

In this embodiment of the utility model, the monitoring device 10 is for monitoring acoustic information and / or visual information from the outside of the door lock and sending the detected acoustic and / or visual information to the main control board 5. In particular, a camera can be used to record conditions on the outside of the door lock, so that the user can monitor the conditions around the door of the house or business in real time using a mobile phone, computer and other devices, which is very convenient.

In this embodiment of the utility model, the event control device 11 is designed to monitor the events of actions of one or more components of the door lock, determine whether such actions are authorized by an authorization command received from the main control board 5, and notify the main control board 5 of an unauthorized action event (including unauthorized door opening).

In this embodiment of the utility model, the alarm device 12 is designed to issue a corresponding loud signal depending on the command to issue an alarm in case of unauthorized action or the command to issue a low-power alarm from the main control board 5. The alarm device 12 can be, in particular, designed to: send a warning to the user's mobile phone when the power supply of the door lock is too low, when the lock is in sleep or deep sleep mode, and send the user a voice prompt to immediately replace batteries when the user uses a door lock.

The wireless communication device 13 is designed to implement wireless information interaction with external devices. External devices include one or more mobile communication devices, a cloud service delivery device, smart home equipment, or a smart wearable device. In particular, the external device is, but is not limited to, a mobile phone, a computer, a cloud server, a smart TV or a group of devices, etc.

In this embodiment of the utility model, specific forms of information interaction may be as follows: the main control board sends to external devices controlled acoustic and / or visual information received from the outside of the door lock and / or a controlled event of the action of one or more components of the door lock, and / or alarm using a wireless communication device.

In some additional embodiments of the utility model, specific forms of information interaction may be as follows: using external devices, remote control and / or configuration of the door lock is performed and / or using external devices, the door lock is jointly controlled.

In particular, the user can configure and remotely control the door lock using an application in a mobile phone. Joint management and control (for example, joint registration of identification information and user password information, joint verification of the user ID, control of information about the environment surrounding the door lock and modification, addition or removal of door lock functions) are performed on the door lock using the door lock control platform in computer, tablet, or cloud server. The communication protocol for information interaction can be: Bluetooth communication protocol, Wi-Fi communication protocol, ZigBee communication protocol, 433 MHz radio communication protocol, etc. Door locks can be classified into a version of a door lock for a home and a version of a door lock for an enterprise. When the door lock is a version of the door lock for the home, the user can realize close information interaction between the mobile phone and the door lock using the Bluetooth communication protocol. For example, a user may configure a door lock, register a user, and the like. When the door lock is a version of the door lock for an enterprise, the user can connect the door lock to the Internet via Wi-Fi to remotely control the door lock.

An application or program can be installed on the door lock control platform to perform the following functions.

1. Registration of a finger vein pattern can be carried out (for example, the number of registered users is 50, and authorization of authorized visitors is provided for a certain period of time).

2. You can set a password (for example, one password for the primary user and several passwords of authorized temporary users with limited validity periods or a limited validity period).

3. The main user can add, delete, modify or verify the registered finger vein pattern or password after passing the test in order to work in the administrator authentication mode (by finger vein pattern or password).

4. Using the application, you can add, delete, modify registered users.

5. Using the application, you can change the configuration of the door lock.

6. The door lock can be activated with your fingers.

7. The safe room mode (ie, the power-off mode) can be set or canceled manually or using a communication terminal.

8. The acoustic mode can be set or canceled.

9. An automatic locking function can be set after closing the door.

10. The auto-lock time can be set.

11. An intrusion detection function can be set in which, in the event of an unintentional opening of a door lock from inside or outside a room, an alarm is given and an automatic alarm is generated.

12. A battery reminder function may be set.

13. Two-factor identification mode may be set.

14. The mode of protection against pampering can be set (if the wrong passwords are entered 5 times, the electronic lock gives an alarm and automatically stops working for 3 minutes).

It is clear that if the functions of the door lock need to be modified, added or deleted, this can be done by modifying the program in the application or in the door lock control platform.

In the present embodiment of the utility model, the password input keyboard 9 is for collecting password information and sending password information to the main control board 5, so that the main control board 5 performs identity verification according to the password information. In particular, the main control board 5 can compare the collected password information with the user password information stored therein. It is believed that the identity check was successful if the collected password information and the stored password information match. The number buttons on the keyboard 9 for entering the password may be highlighted, and the backlight may turn on when the hand is almost touching the keyboard to enter the password.

In this embodiment of the present utility model, the user can use the door lock control platform to uniformly set passwords or can set passwords using a communication terminal. Password forms can be set freely. For example, a password can be set several times or for a certain period of time. This method is usually used to set passwords used by visitors.

The existing door lock password is fixed and the passwords of the respective users are the same. As a result, the password leak situation is very serious. Due to the problem of password leakage, this utility model performs the following special processing based on a cryptographic algorithm.

In one aspect, the password may have a random encoding function. Those. random virtual passwords can be added before or after the password that opens the door, and the system automatically retrieves the real password.

In another aspect, passwords may not be a single password and may be associated with corresponding registered users.

In yet another aspect, variable numbers are added before each password. For example, a date is added before the password.

In this way, password leakage can be prevented and the security of the door lock can be enhanced.

In particular, the user can open the door lock with a password as follows. The user approaches the door lock, touches the location of the keyboard to activate the keyboard and enter a password for identification (or verification). After it is determined that the identification was successful, the locking mechanism starts to work, and information about the passed verification is uploaded to the cloud using Bluetooth or WiFi and sent to the door lock control platform application or to the communication terminal (for example, to the user's mobile phone), so that the user interacts with the door lock using the application.

Thus, in addition to identifying the user with a finger vein pattern, the door lock according to this embodiment of the present utility model can confirm the user identity again with a password. This two-factor configuration is able to provide additional security for the door lock. In addition, the door lock can verify the identity of the user either by drawing the veins of the finger or by password. Such a flexible configuration can eliminate the problem that unregistered legal users will not be able to freely go through the door, thereby improving the experience of use.

In this embodiment of the utility model, the power supply interface 4 may be a battery compartment. In the battery compartment, a power source (for example, 8 AA alkaline batteries) may be pre-located. Alternatively, the batteries are not installed, or the power supply can be installed by the user after installing the door lock. The battery compartment can be easily opened so that the user can easily insert or replace the battery in the lock case from the inside of the room. When the energy of the door lock is too low, a warning is issued on the user's mobile phone, and, moreover, when the user uses the door lock the next time, he receives a reminder to immediately replace the battery. In particular, it can be determined that the reminder is activated when the battery energy is less than 15%. The reminder is a warning sound signal about insufficient energy, and the application forcibly gives out information about the need to replace the battery. When the energy is less than 5%, the door lock will automatically turn off.

In this embodiment of the utility model, the contacts 15 of the electrodes are two open contacts 15 of the electrodes on the front panel 1 from the outside. The contacts of the 15 electrodes are directly connected to the power supply interface 4. In the event of a disconnection, the user can go to a convenience store or a supermarket to buy a spare battery (9 V) and connect it to the electrode contacts to provide temporary power. After the user opens the door, he can replace AA alkaline batteries or charge the door lock with a charger (in this case, the power source must be a battery). The inside can be equipped with an interface for external portable power supplies. The door lock can be powered by an external portable power source for a long time, and the external portable power supply can be hung from an arm on the inside of the door lock. For convenience and economy, the user can also use AA size batteries that can be recharged. Thanks to this design, there is no need to remove or replace the batteries, which reduces the risk of damage to the door lock, prolongs its service life and improves the experience of use.

In this embodiment of the utility model, a mechanical keyhole 14 is concealed in the front panel 1 and is directly connected to the locking mechanism 3. The door lock can also be equipped with several mechanical keys (for example, five) suitable for the mechanical keyhole 14. The door lock becomes an ordinary door lock in case of malfunction or disconnection of the electronic device in the door lock, in which case the user can use a mechanical key to open the door. Thus, the door lock has a “smart” design, and the user can easily cope with some extreme situations, and as a result, the experience of use is significantly improved.

In some further embodiments of the utility model to the basic configuration shown in FIG. 1, one or more of the following components can be added: a password keypad 9, a control device 10, an event control device 11, an alarm device 12, a wireless communication device 13, a keyhole 14, and electrode contacts 15. As a result, such components can be combined in various combinations to provide related functions. For ease of description, various combinations are not reviewed here again. In addition, to provide more functions, redundant interfaces can also be installed on the main control board so that additional components can be added in the future if necessary, improving the characteristics of the door lock.

In FIG. 3 is a schematic structural diagram of a finger vein pattern recognition device according to one embodiment of the utility model. As shown in FIG. 3, the finger vein pattern recognition device comprises a finger receiving cavity 61, an infrared light source 62 and an infrared image receiving device 63.

The finger receiving cavity 61 can be integrated into the opening on the front panel, and the infrared light source 62 and the infrared light receiving device 63 are mounted on the outside of the finger receiving cavity 61. Said finger receiving cavity 61 may be made of transparent plastic, glass and other transparent materials.

Thus, since the finger receiving cavity 61 is integrated into the hole in the front panel (the hole is adapted to the size of the finger, so that when the finger is inserted into the hole, external light cannot penetrate the hole), instead of being located in the open the window. Thus, the light emitted from the infrared light source 62 can be fully utilized, interference from other light sources can be reduced, and the configuration requirements of the infrared light source 62 and the manufacturing cost can also be reduced. Of course, the finger receiving cavity 61 may also be located in other places. For example, it may be located in an open window. Such a design may also solve the problem, but is not able to realize the above effects.

In addition, the device 6 recognition pattern veins of the finger can be highlighted with a two-color lamp. A solid green light means that you are in standby mode, and a blinking green light means that identification is in progress. After determining that the identification was successful, a continuous green light may mean continuing to be in standby mode, and a short notification tone is issued once; flashing red light means that the battery energy is low (less than 15%), and a continuous notification tone is issued for 3 seconds; if it is determined that the identification has failed, the red light flashes once and a short notification tone is issued twice.

The finger vein pattern information collecting device collects features of the finger vein pattern of individuals and thus can prevent counterfeiting compared to fingerprints and other non-living signs.

The user can turn the knob from the inside of the room to unlock the lock, and the door lock again enters a sleep state.

The emergency spare battery interface may be the aforementioned interface and therefore is not considered here again.

The operation of the door lock is illustrated in detail below.

1. A smart door lock with pattern recognition of veins is in sleep mode when it is normally locked and the outer handle is inoperative. If it is detected that someone is approaching, the door lock will automatically wake up and go into control mode. When the user unlocks the door lock using the finger vein pattern recognition device, the finger vein pattern recognition device enters the collection and verification mode. When the user unlocks the door lock with the keypad for entering the password, the keypad for entering the password automatically activates the backlight when the hand is near the keypad and enters the password verification mode. When it is determined that the test was successful in both two modes (or in one of the two modes), the door lock is automatically unlocked and the outer handle returns to the accessible state. At this time, the user can use the external handle to open the door and enter the room, and then the door lock switches to the control mode of the lock cylinder.

2. When the door lock detects the action of retracting the lock cylinder, which indicates that the user has closed the door, the door lock is automatically locked after 2 seconds and the outer handle again goes into an inoperative state.

3. If the user doesn’t close the door loosely (only the lock cylinder was pulled in in the lock cylinder control mode and it is not detected that the lock cylinder returns within 2 seconds), a continuous notification tone sounds to remind the user to close the door tightly.

4. If the user inadvertently touches the door lock while the door is open and then forces the lock cylinder to extend, you can turn the inner handle to retract the lock cylinder.

5. If the door lock is in control mode of the lock cylinder for 5 seconds, the door lock goes back to sleep mode.

6. When the user pushes the lock latch from inside the room, the door lock controls whether the lock cylinder is in the return state. If the lock cylinder is in the return state, the door cannot be directly closed.

7. If the lock cylinder is in the return state, the lock mode is open. The door lock is in the energy-saving deep sleep mode (safe mode) and cannot be removed from this state from the outside by any means of unlocking located outside. In this case, the mechanical cylinder of the lock is locked.

8. The user rotates the handle from the inside of the room to release it from the lock function, and the door lock again enters a sleep state.

In this embodiment of the utility model, the reaction time and the unlocking of the door lock can be set as follows.

1. In the sleeping state, the door lock controls the user's approach by perceiving the human body. The door lock can automatically wake up within one second and go into control mode.

2. The finger vein pattern recognition device needs less than 2 seconds from the moment the user starts to insert the hand to collect the finger vein pattern and verify identity.

3. The cylinder of the door lock opens after 0.5 seconds after it is revealed that the verification of the pattern of the veins of the finger was successful.
