[0024] With the advancement of science and technology, people's demand for intelligence is increasing, and a series of smart home products have been derived to help people live more conveniently. As an important part of modern home security, smart door locks not only provide convenient usage methods, such as fingerprint unlocking, face unlocking, etc., but also bring high-end intelligent experience and considerate security functions, such as visual doorbells and door lock alarms.

[0025] Existing smart door locks usually rely on lithium batteries or dry batteries to power the door locks. In addition, since smart door locks are integrated with power-intensive functions such as monitoring and face recognition, users need to frequently charge the lithium batteries or replace them with new dry batteries. Once the user is outside and the smart door lock is out of power, the user can only open the door by disassembling the panel, exposing the charging port, and connecting an external power bank or mechanical key, which is very inconvenient to use.

[0026] The present invention provides an intelligent door lock, aiming to realize that the intelligent door lock never loses power.

[0027] See also Figure 1 In one embodiment of the present invention, the smart door lock 100 is used to lock the door panel 4 and the door frame 5. The smart door lock 100 includes a door lock body 1 and a power cord 2. The door lock body 1 is used to be installed on the door panel 4; one end of the power cord 2 is connected to the door lock body 1, and the other end is used to be electrically connected to an external power supply.

[0028] In this embodiment, the door lock body 1 is used to be installed on the door panel 4. The door lock body 1 includes an unlocking component, a lock tongue component or a monitoring component. The lock tongue component partially extends out of the door panel 4, and the door panel 4 and the door frame 5 can be locked together. The unlocking component can be a mechanical lock component, a fingerprint recognition component, a password input component or a face recognition component, etc. The unlocking component is linked to the lock tongue component. When the unlocking component is unlocked in the correct way, the lock tongue component can be retracted into the door panel 4 to open the door panel 4. The monitoring component can monitor the environment outside the door, so that the user can obtain information outside the door while inside the door, thereby improving the user's safety.

[0029] The power cord 2 can adopt the common power cord 2 types on the market, including but not limited to two-pin plug power cord 2, three-pin plug power cord 2 or USB, Type-C and other types of power cord 2. Different types of external power sources can be connected through different connectors. For example, the two-pin plug power cord 2 or the three-pin plug power cord 2 can be directly connected to the power socket reserved on the wall, which is more convenient. For example, the power cord 2 of USB or Type-C is suitable for environments where there is no power socket near the door panel 4. It can be connected electrically through a power bank or a socket strip with a USB or Type-C socket. The end of the power cord 2 connected to the door lock body 1 can be directly welded to the circuit board of the door lock body 1, or a power supply interface can be set on the circuit board of the door lock body 1. The end of the power cord 2 connected to the door lock body 1 is provided with a plug. The electrical connection between the power cord 2 and the door lock body 1 is realized by plugging the plug with the power supply interface. The specific connection method between the power cord 2 and the door lock body 1 is not further limited here. The power cord 2 can be set on the surface of the door panel 4 facing the interior, and hidden by decorative parts, so as not to affect the aesthetics of the door panel 4 itself; or a connection channel for the power cord 2 to be concealed can be opened in the door panel 4, so that the power cord 2 can be hidden inside the door panel 4 to avoid affecting the aesthetics of the surface of the door panel 4.

[0030] In a preferred embodiment, the door lock body 1 is also provided with a built-in power supply, which can be a rechargeable lithium battery, a replaceable dry battery, or both. This can prevent the external power supply from being unable to power the door lock body 1 during a power outage, resulting in an inability to open the door, thereby improving the user experience.

[0031] The technical solution of the present invention uses a power cord 2 to connect the door lock body 1 and the external power supply to maintain the electrical connection between the door lock body 1 and the external power supply. When there is no power outage, the smart door lock 100 can be powered on, eliminating the trouble of frequent battery replacement or frequent lithium battery charging for users, improving user experience, and fundamentally solving the battery anxiety of some people who are away from home all year round. The smart door lock 100 can also solve the pain point of users monitoring the outside of the door in real time without power outage, improving user safety.

[0032] In an embodiment of the present invention, the door lock body 1 is provided with a power supply interface electrically connected to the door lock body 1 , and one end of the power cord 2 is inserted into the power supply interface to be electrically connected to the door lock body 1 .

[0033] In this embodiment, the door lock body 1 is provided with a power supply interface electrically connected to the circuit board of the door lock body 1, and one end of the power cord 2 is plug-connected to the power supply interface, so that one end of the power cord 2 is electrically connected to the circuit board of the door lock body 1 to provide power for various functions of the door lock body 1. The plug-in connection method can make the connection between the power cord 2 and the circuit board more flexible, which is convenient for users to assemble by themselves, and when there is a problem with the power cord 2, a new power cord 2 can be replaced by plugging and unplugging to rule out whether the power cord 2 has a short circuit or a broken circuit. The door panel 4 and the door frame 5 are hinged, and the hinge connection is a common connection method for anti-theft doors in homes. It can be understood that the door panel 4 and the door frame 5 can also be connected by a sliding connection.

[0034] In the embodiment of the present invention, the door panel 4 and the door frame 5 are hinged by a hinge, the hinge is provided with an escape hole, and the other end of the power cord 2 passes through the escape hole to be electrically connected to the external power supply.

[0035] In this embodiment, the other end of the power cord 2 passes through the avoidance hole on the hinge to be electrically connected to the external power supply, making the power cord 2 more concealed so as not to affect the aesthetics of the door panel 4; and the hinge can provide a certain support force for the power cord 2 to prevent the power cord 2 from falling to the ground due to gravity and tripping the user entering and leaving the door. It is understandable that in other embodiments, an additional hinge can also be provided, connected between the door panel 4 and the door frame 5, and the other end of the power cord 2 is passed through the hinge to be electrically connected to the external power supply.

[0036] In an embodiment of the present invention, the smart door lock 100 also includes an adapter 3, which is used to be arranged on a door panel 4 or a door frame 5. The other end of the power cord 2 is electrically connected to the adapter 3, and the adapter 3 is electrically connected to an external power supply to conduct electricity between the door lock body 1 and the external power supply.

[0037] In this embodiment, the power cord 2 is connected to the external power supply through the adapter 3 to realize the electrical connection between the smart door lock 100 and the external power supply, thereby realizing the permanent power supply of the smart door lock 100. Compared with the method of directly connecting the power cord 2 to the external power supply, the advantages of connecting through the adapter 3 are as follows: first, it has strong flexibility and adjustability, and can adapt to different installation positions and installation environments; second, the connection path between the door lock body 1 and the external power supply has multiple components. When the path is broken, only the problematic component needs to be replaced to complete the repair of the entire path, thereby reducing the subsequent maintenance cost.

[0038] In an embodiment of the present invention, the adapter 3 is a spring pin assembly, which includes a spring pin portion and a trigger portion. The spring pin portion is used to be arranged on a surface of the hinge located on the door frame 5, and the trigger portion is used to be arranged on a surface of the hinge located on the door panel 4; the trigger portion is electrically connected to the other end of the power cord 2. When the hinge is closed, the trigger portion abuts against the spring pin portion to connect the door lock body 1 and the external power supply.

[0039] In this embodiment, a spring pin assembly is used as the adapter 3. The spring pin assembly includes a spring pin part and a trigger part. The spring pin part is used to be installed on one surface of the hinge located on the door frame 5, and the trigger part is used to be installed on the other surface of the hinge located on the door panel 4. It can be understood that the spring pin part and the trigger part can also be installed in an interchangeable position. As long as the hinge is closed, the trigger part can abut against and press the spring pin part to connect the circuit. The trigger part is electrically connected to the other end of the power cord 2. The specific connection method can be a welding connection or a plug-in connection, which is not further limited here. Of course, in another embodiment, since the hinge is usually made of metal and can conduct electricity, the hinge on one side can be used as the trigger part. When the hinge is closed, the hinge on one side abuts against the spring pin part to connect the circuit.

[0040] It should be noted that when a spring pin assembly is used as the adapter 3, when the door panel 4 is away from the door frame 5, that is, when the door is opened, the spring pin part will not be pressed due to the open hinge, so that the circuit between the door lock body 1 and the external power supply is disconnected. At this time, the door lock body 1 needs to be provided with a built-in power supply such as a lithium battery or a dry cell to maintain the normal function of the door lock body 1. When the door panel 4 is closed, the circuit is turned on and switched to an external power supply, and the built-in power supply such as a lithium battery can be charged, further improving the convenience of using the smart door lock 100.

[0041] In an embodiment of the present invention, the smart door lock 100 also includes a controller and an alarm. The controller is electrically connected to the trigger part, and the alarm is electrically connected to the controller. The controller is used to detect whether the trigger part is electrically connected to the spring pin part and control whether the alarm sounds an alarm.

[0042] In this embodiment, a spring pin assembly is used as an adapter 3 for electrical connection, and has the characteristics of power off when the door is opened and electrical conduction when the door is closed. While ensuring that the door is always powered on when the door is closed, it can be used to detect whether the door lock is opened and closed normally, which can simplify the design of the traditional lock body, save the design of the detection tongue of the traditional lock body, and fundamentally reduce the sound of the detection tongue hitting the detection buckle plate, thereby improving the user experience. A controller is provided to detect whether the spring pin assembly is electrically conductive. If the circuit is not conductive after the door is closed, it means that the door is not completely closed and there is a safety hazard. At this time, the controller controls the alarm to sound an alarm to remind the user that the door is not closed tightly, thereby improving the safety of the use of the smart door lock 100.

[0043] In an embodiment of the present invention, the adapter 3 is a slip ring assembly, the stationary part of the slip ring assembly is used to be arranged on the door frame 5, the rotating part of the slip ring assembly is used to be arranged on the door panel 4, the rotating part is electrically connected to the other end of the power cord 2, and the rotating part is electrically connected to the stationary part to connect the door lock body 1 with the external power supply.

[0044] In this embodiment, the slip ring is an electrical component that transmits power, signals, and even fluids between a rotating body and a fixed body. It allows the transmission of power, signals, and data between the rotating part and the fixed part of a device or machine while maintaining rotatability, and is very suitable for use on a hinged door panel 4 and a door frame 5. The stationary part of the slip ring assembly is arranged on the stationary door frame 5, and the rotating part of the slip ring assembly is arranged on the door panel 4 that is rotatably connected to the door frame 5. It always keeps contact with the stationary part through a brush or a contact ring, and keeps contact with the rotating part while keeping contact with the rotating part, thereby realizing stable current transmission between the stationary part and the rotating part. The advantage of using a slip ring assembly as an adapter 3 is that it can ensure that the door lock body 1 is electrically connected to the external power supply for a long time, and the electrical connection will not be disconnected due to opening the door, further improving the convenience of using the smart door lock 100.

[0045] In an embodiment of the present invention, a contact is respectively provided at the corresponding position of the door panel 4 and the door frame 5, the contact of the door panel 4 is electrically connected to the door lock body 1 through the power line 2, and the contact of the door frame 5 is electrically connected to the external power supply. When the door panel 4 and the door frame 5 are closed, the two contacts are in contact to electrically connect the door lock body 1 with the external power supply.

[0046] In this embodiment, two electrically connectable contacts are used as the adapter 3 to electrically connect the door lock body 1 and the external power supply. A contact electrically connected to the external power supply is provided on the door frame 5. The specific way of electrically connecting the contact to the external power supply can be a wired connection. The contact on the door panel 4 is electrically connected to the door lock body 1. When the door panel 4 is closed on the door frame 5, the contact on the door panel 4 abuts against the contact on the door frame 5 to form a passage. The door lock body 1, the power line 2, and the two contacts are connected to the external power supply to form a current path, so that the smart door lock 100 will never be powered off when the external power supply is not powered off, thereby improving the user experience.

[0047] In an embodiment of the present invention, the smart door lock 100 also includes a torsion driving component, which is arranged on the door frame 5 and electrically connected to the door lock body 1 , and the driving part of the torsion driving component drives the connected door panel 4 .

[0048] In this embodiment, the smart door lock 100 also includes a torsion drive component, a fixed portion of which is arranged on the door frame 5, and a driving portion drives the connected door panel 4. The torsion drive component can drive the door panel 4 to rotate relative to the door frame 5 to achieve the effect of automatically opening or closing the door. When it is inconvenient for the user to open the door by carrying something, the door can be opened without manual operation.

[0049] In an embodiment of the present invention, the smart door lock 100 further includes an angle sensor, which is electrically connected to the door lock body 1 , and is used to detect the opening angle of the door panel 4 .

[0050] In this embodiment, an angle sensor is provided to detect the opening angle of the door panel 4. According to the obtained opening angle information, when the torsion drive is linked, the opening angle of the door panel 4 relative to the door frame 5 can be controlled to prevent the door panel 4 from being over-opened and hitting the wall. The torsion drive can also be controlled to close the door according to the opening angle of the door panel 4, freeing the user's hands and improving the convenience of using the smart door lock 100. It can be understood that in another embodiment, an angle sensor is provided at the hinge, and the opening and closing angle of the door panel 4 relative to the door frame 5 can be obtained by detecting the opening angle of the hinge. Since the size of the hinge is relatively small compared to the door panel 4, it is more convenient to detect.

[0051] The above description is only an exemplary 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 technical 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.
