[0036] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0037] Reference Figure 1 As shown, an embodiment of the present disclosure provides a smart door lock, which may include a housing 1, a camera assembly 2, and a drive assembly 3. The housing 1 has a cavity 1a and a first sidewall 11 having a through hole 11a. The camera assembly 2 is located in the cavity 1a, and the shooting direction of the camera assembly 2 is opposite to the through hole 11a. The drive assembly 3 is connected to the housing 1 and the camera assembly 2 respectively, and is used to adjust the shooting direction of the camera assembly 2.

[0038] Adjusting the shooting direction of the camera assembly 2 includes changing the pitch angle and the yaw angle. The pitch angle is the rotation of the camera assembly 2 about the first direction A and the second direction B as the axis, and the yaw angle is the rotation of the camera assembly 2 about the third direction C and the fourth direction D as the axis.

[0039] The driving component 3 drives the camera component 2 to rotate, thereby expanding the shooting range of the camera component 2 to the surroundings, realizing face recognition within a larger range, which is conducive to successfully identifying the faces of users of different heights and standing positions, and increasing the convenience of using the smart door lock.

[0040] Reference Figure 5 As shown, in some embodiments, the drive assembly 2 can communicate with a mobile terminal (e.g., a smartphone, smartwatch, etc.) via a wireless network, and the user can use the mobile terminal to adjust the shooting angle of the camera assembly 2. For example, when a small item such as a courier is placed at the door, the user can use the mobile terminal to control the drive assembly 2 to adjust the shooting direction of the camera assembly 2 toward the ground, thereby allowing the user to view and monitor the small item on the ground.

[0041] Reference Figure 2 As shown, in some embodiments, the driving component 3 includes a first magnetic component 31, a second magnetic component 32 and a controller. The first magnetic component 31 and the second magnetic component 32 are both electromagnetic components. The first magnetic component 31 is fixed in the shell 1, and the second magnetic component 32 is fixed on the camera component 2. The first magnetic component 31 and the second magnetic component 32 are electrically connected to the controller respectively. Under the control of the controller, the first magnetic component 31 and the second magnetic component 32 can generate electromagnetic force with each other to drive the camera component 2 to move relative to the shell 1 to adjust the shooting direction of the camera component 2.

[0042] The first magnetic component 31 and the second magnetic component 32 are both electromagnetic components. On the one hand, the magnetic field strength of the electromagnetic component can be precisely controlled by adjusting the magnitude and direction of the current, thereby meeting the needs of different application scenarios of the smart door lock; on the other hand, the electromagnetic component can withstand heat to higher temperatures and can work for a long time in a high temperature environment, while the permanent magnet component may lose its magnetism under high temperature conditions, thereby affecting its performance.

[0043] In some embodiments, the first electromagnetic component 31 includes a first electromagnet 311 and a first electromagnetic control circuit, the first electromagnetic control circuit is electrically connected to the first electromagnet 311, and the second magnetic component 32 includes multiple second electromagnets 321 and a second electromagnetic control circuit, the multiple second electromagnets 321 are opposite to the first electromagnet 311, and the second electromagnetic control circuit is electrically connected to the multiple second electromagnets 321.

[0044] In this way, the magnetic properties of one first electromagnet 311 and one second electromagnet 321 can be controlled to be opposite, while the magnetic properties of the other second electromagnets 321 can be the same. Consequently, the first electromagnets 311 and second electromagnets 321 with opposite magnetic properties can be made to face each other under the action of magnetic force. When the shooting direction of the camera assembly 2 needs to be changed, the magnetic properties of one first electromagnet 311 and another second electromagnet 321 can be controlled to be opposite, while the magnetic properties of the other second electromagnets 321 can be the same. Under the action of magnetic force, the position where the first electromagnet 311 faces each other is gradually replaced by the second electromagnet 321 that originally had opposite magnetic properties to the first electromagnet 311. The camera assembly 2 can then be moved by a predetermined angle to achieve a change in shooting direction, thereby improving the success rate of recognizing the faces of users of different heights and standing positions.

[0045] In some embodiments, the driving component 3 includes a first electromagnetic component 31, a second magnetic component 32 and a controller. The first electromagnetic component 31 is a permanent magnet component, and the second magnetic component 32 is an electromagnetic component. The first electromagnetic component 31 is fixed in the shell 1, and the second magnetic component 32 is fixed on the camera component 2. The second magnetic component 32 is electrically connected to the controller. Under the control of the controller, the second magnetic component 32 can generate electromagnetic force with the first electromagnetic component 31 to drive the camera component 2 to move relative to the shell 1 to adjust the shooting direction of the camera component 2.

[0046] The first electromagnetic component 31 adopts a permanent magnet component. On the one hand, the permanent magnet has its own fixed magnetism and does not require external current to activate or maintain its magnetic field, thereby reducing the overall power consumption of the smart door lock; on the other hand, compared with the electromagnetic component, the permanent magnet is simpler in structure and does not require corresponding circuits and control elements to ensure its magnetism.

[0047] In some embodiments, the first electromagnetic component 31 includes a permanent magnet 312 , the second magnetic component 32 includes multiple second electromagnets 321 and a second electromagnetic control circuit, the multiple second electromagnets 321 are opposite to the permanent magnet 312 , and the second electromagnetic control circuit is electrically connected to the multiple second electromagnets 321 .

[0048] For example, if the end of the permanent magnet 312 near the second magnetic assembly 32 is at its north pole, one second electromagnet 321 near the permanent magnet 312 can be controlled to have its south pole, while the other second electromagnet 321 near the permanent magnet 312 has its north pole. Consequently, the magnetic force can cause the first electromagnet 311 and the second electromagnet 321, which have opposite magnetic properties, to face each other. To change the shooting direction of the camera assembly 2, the end of another second electromagnet 321 near the permanent magnet 312 can be controlled to have its south pole, while the other second electromagnet 321 near the permanent magnet 312 has its north pole. Under the action of the magnetic force, the position facing the permanent magnet 312 is gradually replaced by the second electromagnet 321 that originally had opposite magnetic properties to the permanent magnet 312. This allows the camera assembly 2 to move a predetermined angle, changing the shooting direction and improving the success rate of recognizing the faces of users of different heights and standing positions.

[0049] The present disclosure does not limit the shape and size of the permanent magnet 312 , and the shape and size of the permanent magnet 312 can be matched and set according to the shape and size of the housing 1 and the shape and size of the second electromagnet 321 .

[0050] Reference Figure 4 As shown, in some embodiments, the driving component 3 includes multiple first electromagnetic components 31 and multiple second magnetic components 32, wherein the two second magnetic components 32 are respectively located in the first direction A and the second direction B of the camera component 2, and the first direction A and the second direction B are opposite.

[0051] For example: Figure 4 In Figures ① to ②, the camera assembly 2 is rotated a certain angle toward the first direction A with the third direction C and the fourth direction D as the axis, thereby achieving a shift of the shooting range of the camera assembly 2 toward the first direction A.

[0052] In some embodiments, the two second magnetic components 32 are respectively located in the third direction C and the fourth direction D of the camera assembly 2 , and the third direction C and the fourth direction D are opposite.

[0053] For example: Figure 4 In Figures ① to ③, the camera assembly 2 is rotated by a certain angle toward the fourth direction D with the first direction A and the second direction B as the axis, thereby achieving a shift of the shooting range of the camera assembly 2 toward the fourth direction D.

[0054] A straight line connecting the third direction C and the fourth direction D is not parallel to a straight line connecting the first direction A and the second direction B.

[0055] In some embodiments, a straight line connecting the third direction C and the fourth direction D is perpendicular to a straight line connecting the first direction A and the second direction B. Changes in the shooting direction of the camera assembly 2 can be divided into a combination of left and right angular swings with the third direction C and the fourth direction D as axes, and pitch angular swings with the first direction A and the second direction B as axes.

[0056] In some embodiments, the plurality of second electromagnets 321 in each second magnetic assembly 32 are distributed along the fifth direction E.

[0057] The facing position of the first electromagnetic component 31 is achieved by different transformations of multiple second electromagnets 321 located in the first direction A and the second direction B and distributed along the fifth direction E, which can realize the left and right angular swing of the camera component 2 with the third direction C and the fourth direction D as the axis.

[0058] The facing position of the first electromagnetic component 31 is achieved by different transformations of multiple second electromagnets 321 located in the third direction C and the fourth direction D and distributed along the fifth direction E, which can realize the pitch angle swing of the camera component 2 with the first direction A and the second direction B as the axis.

[0059] In some embodiments, the fifth direction E is the axial direction of the through hole 11a, and the fifth direction E, the first direction A, and the third direction C are perpendicular to each other. Furthermore, the first direction A can be the width direction of the housing 1, and the third direction C can be the length direction of the housing 1. This facilitates the installation of the first magnetic assembly 31, the second magnetic assembly 32, and the camera assembly 2 within the cavity 1a, thereby improving the production efficiency of the smart door lock.

[0060] The fifth direction E is also perpendicular to the operating panel of the smart door lock, that is, the user usually stands in front of the operating panel to perform relevant operations on the smart door lock. The camera component 2 is more likely to capture the user's face in the fifth direction E and within a certain rotation range, so the initial shooting direction of the camera component 2 can be parallel to the fifth direction E.

[0061] In some embodiments, the housing 1 further includes a bracket 12, to which the camera assembly 2 is connected. The bracket 12 is used to limit the movement of the camera assembly 2 in the fifth direction E. The bracket 12 can prevent the camera assembly 2 from moving in the fifth direction E or in a direction opposite to the fifth direction E. For example, when a user passes through the through hole 11a and accidentally touches the camera assembly 2, the bracket 12 is connected to the camera assembly 2, preventing the user's accidental touch from causing the camera assembly 2 to move. As a result, the first magnetic assembly 31 and the second magnetic assembly 32 will no longer correspond to each other, and the camera assembly 2 will not be driven to rotate under the action of the magnetic force.

[0062] The smart door lock further includes a human body sensing sensor 4 , which is located on the outer surface of the first side wall 11 and connected to the first side wall 11 . The human body sensing sensor 4 is electrically connected to the controller.

[0063] The human presence sensor 4 is a sensor that can detect the presence or movement of a person. When a person enters its sensing area, the human presence sensor 4 can identify the person's infrared radiation or microwave signals and feed the detection results back to the controller. The controller can then control the first magnetic component 31 and the second magnetic component 32 to generate corresponding magnetic forces, driving the camera component 2 to rotate and identify the faces of people around the smart door lock. The recognition results can then be used to perform subsequent related operations (such as unlocking, activating an alarm signal, etc.).

[0064] The provision of the human body sensing sensor 4 can prevent the first magnetic component 31 and the second magnetic component 32 from working or standing by for a long time, thereby reducing the overall energy consumption of the smart door lock and increasing the service life of the smart door lock.
