Moreover, the control component of the door lock can transmit the image received from the camera of the door lock to the mobile terminal for display. According to the setting of the present disclosure, the door lock of the present disclosure can achieve the display of the picture without a built-in display screen. Such a setting saves the manufacturing cost of the door lock and also reduces the selling cost of the door lock, enabling smart home products to be popularized to more user families and allowing more families to enjoy the benefits brought by the development of technology. Furthermore, such a setting can effectively utilize the idle mobile terminals in the home, realizing the rational utilization of resources and avoiding waste.

[0025] Figure 1 It is a schematic structural diagram of a door lock shown according to an exemplary embodiment. Figure 2 It is a schematic structural diagram of a door lock installed with a mobile terminal shown according to an exemplary embodiment.

[0026] Such as Figure 1 AndFigure 2 As shown, the door lock of the present disclosure may include a control component, a housing 10, and an image acquisition component 301. The control component may be disposed inside the housing 10, and the image acquisition component 301 may be disposed on the housing 10 and configured to acquire images. Exemplarily, the image acquisition component 301 may be a camera.

[0027] The housing 10 may have a first surface and a second surface opposite to each other. The image acquisition component 301 may be disposed on the first surface. Exemplarily, when the door lock is installed on a door body, the first surface may face outside the door, and the second surface may face inside the door.

[0028] In an exemplary embodiment of the present disclosure, as Figure 1 and Figure 2 shown, a sensing module 302 may be further disposed on one side of the image acquisition component 301. When the sensing module 302 senses that an object is approaching, the control component may control the image acquisition component 301 to start acquiring images.

[0029] In an exemplary embodiment of the present disclosure, the sensing module 302 may be an infrared sensing device.

[0030] In an exemplary embodiment of the present disclosure, as Figure 1 shown, the housing 10 may include an inner housing 100 and an outer housing 200. Generally, the inner housing 100 may be disposed inside the door, and the outer housing 200 may be disposed outside the door. The first surface may be disposed on the outer housing 200, and the second surface may be disposed on the inner housing 100. As Figure 1 shown, the inner housing 100 may be provided with a receiving portion 101, and the receiving portion 101 may be configured to place the mobile terminal 20.

[0031] However, the present disclosure is not limited thereto. In some embodiments, the outer housing 200 may be provided with a receiving portion 101 for detachably placing the mobile terminal 20.

[0033] As Figure 1 and Figure 2 shown, the mobile terminal 20 may be detachably placed in the receiving portion 101. For example, a user may place an idle mobile terminal at home, such as a mobile phone, a tablet, a reader, etc., in the receiving portion 101.

[0034] When the mobile terminal 20 is disposed in the receiving portion 101, the control component may be configured to transmit the image acquired by the image acquisition component 301 to the mobile terminal 20, and cause the mobile terminal 20 to display the image on the display screen of the mobile terminal 20 based on an application program.

[0035] Among them, the control component of the door lock can be matched with the application program of the mobile terminal 20. Exemplarily, the firmware protocol of the door lock can be matched with the application program of the mobile terminal 20.

[0036] Through the above configuration, the door lock can display the screen without a built-in display screen. Such a setting saves the manufacturing cost of the door lock and also reduces the selling cost of the door lock, enabling smart home to be popularized to more user families and allowing more families to enjoy the benefits brought by the development of technology. Moreover, such a setting can effectively utilize the idle mobile terminals in the family, realizing the rational utilization of resources and avoiding waste.
