[0045] Combination Figures 1 to 6 As shown, an embodiment of the present disclosure provides a refrigerator door assembly, which includes: a compartment 10, a door 20, a center beam 30, a human sensing device 60, a camera assembly 40 and a display device 70. The compartment 10 defines a storage space with an opening; the box door 20 is rotatably covered on the opening; the middle beam 30 is arranged on the side of the box door 20 facing the compartment 10 and extends vertically to define an installation space, and a slot 321 extending vertically is opened on the wall of the middle beam 30 facing the storage space; the human sensing device 60 is arranged on the box door 20 for detecting whether there is a user in front of the box door 20; the camera assembly 40 is movably arranged in the installation space, and partially extends from the middle beam 30 from the slot 321, for capturing image information in the storage space; the display device 70 is arranged on the wall of the box door 20 away from the compartment 10, and the display device 70 is wirelessly connected to the camera assembly 40 for receiving and displaying image information captured by the camera assembly 40; wherein the camera assembly 40 is electrically connected to the human sensing device 60 for working according to the detection result of the human sensing device 60.

[0046] According to the embodiment of the present disclosure, a storage space with an opening is defined in the compartment 10, and a user can take items out of the storage space through the opening. By rotatably covering the opening with the door 20, on the one hand, the door 20 can cover the opening to ensure the sealing of the storage space, and on the other hand, the user can open or close the storage space by rotating the door 20.

[0047] By setting the middle beam 30, the middle beam 30 defines the installation space, which not only provides sufficient space for the installation of the camera assembly 40, facilitates the installation and maintenance of the camera assembly 40, but also prevents items in the storage space from falling or accidentally colliding with the camera assembly 40 to cause damage. In addition, it can also prevent the camera assembly 40 from being directly affected by the cold air in the storage space, thereby preventing the camera assembly 40 from being inflexible. The notch 321 opened on the wall of the middle beam 30 facing the storage space can facilitate the camera 44 of the camera assembly 40 to extend toward the storage space and facilitate the adjustment of the position of the camera assembly 40. The camera assembly 40 can be movably arranged in the installation space, and part of the middle beam 30 extends out of the notch 321, so that the position of the camera assembly 40 can be flexibly adjusted, and the shooting effect of the camera assembly 40 can be guaranteed.

[0048] The human sensing device 60 is provided at the door 20. The human sensing device 60 can automatically detect whether a user is approaching the door 20, without manual operation by the user, thereby improving the intelligent use. The camera assembly 40 is electrically connected to the human sensing device 60, and the camera assembly 40 is configured to work according to the detection result of the human sensing device 60. Specifically, when the human sensing device 60 detects that there is a user in front of the door 20, a signal is sent, and the camera assembly 40 receives the signal and starts to capture image information in the storage space. In this way, the human sensing device 60 can automatically control the start and stop of the camera assembly 40, thereby avoiding unnecessary energy waste.

[0049] The display device 70 is arranged on the wall of the door 20 away from the compartment 10, that is, the display device 70 is arranged on the front wall of the door 20, so that not only can the space on the door 20 be fully utilized, making the display device 70 easier to install and use, but also the user can conveniently view the image information on the display device 70. The display device 70 is wirelessly connected to the camera assembly 40, which can avoid the limitation and interference of cables and improve the installation convenience of the display device 70 and the camera assembly 40.

[0050] With this embodiment, when a user approaches the refrigerator, the camera assembly 40 will automatically start and capture image information in the storage space, and then the display device 70 will receive and display the image information. The user can understand the items in the refrigerator by viewing the image information on the display device 70, thereby avoiding the trouble of frequently opening the refrigerator door 20, and can effectively shorten the time the user opens the door to find items, thereby reducing the energy consumption of the refrigerator.

[0051] Specifically, the display device 70 and the camera assembly 40 may be wirelessly connected via WiFi or Bluetooth.

[0052] Optionally, the camera assembly 40 includes: a transmission belt 43, a motor 41 and a camera 44, the transmission belt 43 is arranged to extend vertically; the motor 41 is drivingly connected to the transmission belt 43, and the motor 41 is used to drive the transmission belt 43 to rotate; the camera 44 is connected to the transmission belt 43 to rise or fall driven by the transmission belt 43; wherein the motor 41 and the camera 44 are both electrically connected to the human sensing device 60, and work according to the detection results of the human sensing device 60.

[0053] By using the embodiment of the present disclosure, the motor 41 can drive the transmission belt 43 to rotate, thereby causing the camera 44 to rise or fall under the drive of the transmission belt 43. This allows the camera assembly 40 to operate automatically, reduces manual intervention, and improves work efficiency.

[0054] Specifically, the shape of the notch 321 is linear, and the notch 321 is extended along the up-down direction.

[0055] In this way, the camera 44 completes one shot when it moves from the lower end to the upper end of the slot 321 or moves along the upper end of the slot 321 under the drive of the motor 41. The motor 41 reverses for the next shot, and the position of the camera 44 is adjusted by continuously switching the rotation direction of the motor 41. This can effectively reduce the connection area between the installation space and the storage space, and reduce the cold air flowing from the storage space into the installation space.

[0056] Specifically, the motor 41 is a stepping motor.

[0057] In this way, the stepper motor can start, stop and reverse quickly, and has a fast response speed, which can avoid the situation where the transmission belt 43 moves too far and causes the camera 44 to collide with the second housing 32. The accuracy of the motor 41 driving can be effectively improved, and the reliability of the camera assembly 40 can be improved.

[0058] Optionally, the refrigerator door assembly further includes a door status detection device, which is disposed on the door 20 and is used to detect the opening and closing of the door 20. The camera assembly 40 is configured to operate according to the detection result of the door status detection device.

[0059] In this way, the door state detection device can detect the open and close state of the box door 20, and the camera assembly 40 can automatically work according to the detection result, thereby realizing automatic control and providing users with a more convenient use experience.

[0060] Specifically, when the door 20 is in an open state, the camera assembly 40 stops working, and when the door 20 is in a closed state, the camera assembly 40 works. This can effectively protect the privacy of the user and prevent the camera assembly 40 from capturing information outside the storage space or related information of the user.

[0061] Specifically, the door state detection device can be a door magnetic sensor, a mechanical limit switch, or an ultrasonic sensor. It can be understood that the specific structural form of the door state detection device is not unique.

[0062] Preferably, the door state detection device is an ultrasonic sensor.

[0063] In this way, the ultrasonic sensor can not only detect the opening and closing state of the door body, but also detect the position state of the door body. The ultrasonic sensor also has the advantages of high precision, high reliability, high anti-interference ability, low cost and easy maintenance.

[0064] Optionally, the transmission belt 43 is a toothed transmission belt, and the inner wall surface of the toothed transmission belt is provided with tooth grooves; the camera assembly 40 also includes: a gear set 42, the gear set 42 is connected to the motor 41, and the gear set 42 is meshed with the tooth grooves of the transmission belt 43, so that the motor 41 is driven and connected to the transmission belt 43 through the gear set 42.

[0065] According to the embodiment of the present disclosure, by setting the transmission belt 43 as a toothed transmission belt and connecting it to the motor 41 through the gear set 42, the meshing of the toothed transmission belt and the gear set 42 can provide a more stable and reliable transmission. Through the gear set 42, the rotational motion of the motor 41 can be more accurately transmitted to the transmission belt 43, thereby ensuring that the camera 44 can be accurately moved and positioned. In addition, the meshing of the toothed transmission belt and the gear set 42 can not only reduce friction and wear, extend the service life of the camera assembly 40, but also reduce the generation of noise and improve the comfort of use.

[0066] Specifically, the gear set 42 includes a first gear, a second gear and a third gear. The first gear is connected to the output shaft of the motor 41 , the second gear is meshed with the transmission belt 43 , and the third gear is meshed with both the first gear and the second gear.

[0067] In this way, by adopting the transmission form of multi-stage gears, the transmission efficiency can be improved, the transmission range can be expanded, the transmission stability can be improved, and a better user experience can be provided for users.

[0068] Optionally, the human sensing device 60 includes a photosensor and a thermal imaging sensor. When the photosensor and the thermal imaging sensor are triggered simultaneously and the triggering time of the photosensor is greater than or equal to a preset time, the human sensing device 60 sends a signal.

[0069] With the disclosed embodiment, the human sensing device 60 uses a photosensitive sensor and a thermal imaging sensor for detection. The photosensitive sensor can detect changes in light, while the thermal imaging sensor can detect the heat distribution of the human body. The combination of the two can more accurately determine whether a person is approaching, thereby improving the accuracy of detection by the human sensing device 60. When the photosensitive sensor and the thermal imaging sensor are triggered at the same time and the triggering time is greater than or equal to the preset time, the camera assembly 40 can be prevented from working when the user briefly passes in front of the door 20, and false triggering can be avoided to effectively reduce the startup frequency of the camera assembly 40 and reduce the energy consumption of the refrigerator door assembly.

[0070] It should be noted that the preset time may be 2 seconds, 2.5 seconds, or 3 seconds, and the value of the preset time is not unique.

[0071] Specifically, when the photosensitive sensor detects that an object has been staying within its recognition distance for more than 2 seconds, and the thermal imaging sensor recognizes that the object has a temperature of 35-40°C, the human sensing device 60 is triggered to start and send a signal. In this way, it can accurately detect whether a human body is approaching the door 20, avoiding the occurrence of false triggering.

[0072] Optionally, the center beam 30 includes: a first shell 31 and a second shell 32, and the second shell 32 is detachably connected to the first shell 31; wherein the first shell 31 and the second shell 32 jointly define an installation space, and a limiting groove 311 is provided on the wall surface of the first shell 31 facing the second shell 32 so that the transmission belt 43 is embedded in the limiting groove 311.

[0073] According to the disclosed embodiment, by dividing the center beam 30 into a first shell 31 and a second shell 32, the installation of the center beam 30 can be made more convenient. The user can install the first shell 31 and the second shell 32 separately, and then connect them together, thereby simplifying the installation process. By setting the first shell 31 and the second shell 32 to be detachably connected, when the components in the center beam 30 need to be maintained or replaced, the user can remove the second shell 32 without removing the entire center beam 30, thereby improving the convenience of maintenance. The limiting groove 311 is provided on the wall surface of the first shell 31 facing the second shell 32, which can effectively enhance the limiting effect of the transmission belt 43. When the transmission belt 43 is embedded in the limiting groove 311, it can be ensured that the transmission belt 43 will not be separated from the center beam 30 during the movement, forming a fixed movement trajectory, thereby improving the movement stability and accuracy of the camera assembly 40.

[0074] Optionally, the camera assembly 40 further includes: a heating wire 45 , which is sleeved on the camera head 44 and is used to heat the camera head 44 .

[0075] According to the embodiment of the present disclosure, by providing a heating wire 45 and sleeved on the camera 44, the heating wire 45 can heat the camera 44, thereby avoiding frost or ice on the lens due to low temperature, thereby maintaining the clarity of the camera 44. In addition, by heating the camera 44, the influence of low temperature on the camera 44 can be avoided, thereby extending its service life.

[0076] Optionally, the camera 44 is an ultra-wide-angle camera 44 .

[0077] In this way, in a small space, the ultra-wide-angle camera 44 can capture a wider field of view and more details and information, which is conducive to the user to better understand the environment in the storage space.

[0078] Optionally, the display device 70 includes a display screen, and the display screen is configured to display the image information captured last time and the image information captured this time.

[0079] With the disclosed embodiment, the display screen is configured to display the image information of the last shot and the image information of the current shot. By displaying the image information of the last shot and the image information of the current shot, the user can have a more comprehensive understanding of the changes in the items in the storage space.

[0080] Specifically, the upper half of the display screen displays the last captured image information, and the lower half of the display screen displays the current captured image information. In this way, the user can timely discover the status and difference changes of the items in the storage space by comparing the last captured image information with the current captured image information, which is convenient for the user to search or take and place items.

[0081] Optionally, the box door 20 includes a first door body 21 and a second door body 22, the first door body 21 and the second door body 22 are arranged side by side, the middle beam 30 is arranged between the first door body 21 and the second door body 22, and the middle beam 30 is rotatably connected to the first door body 21.

[0082] According to the embodiment of the present disclosure, by arranging the first door body 21 and the second door body 22, when the two door bodies are arranged side by side, they can be opened at the same time, providing a larger opening space for the user, and conveniently placing or taking out large items. By arranging the middle beam 30 between the first door body 21 and the second door body 22, that is, the middle beam 30 is located in the middle of the opening, the camera position of the camera assembly 40 can be ensured, and in addition, the space occupied by the middle beam 30 on the side of the box door 20 facing the storage space can be reduced to ensure the normal use of the shelf.

[0083] Optionally, the refrigerator door assembly further includes: a wireless power supply module 50 , which is disposed in the installation space and is used to supply power to the camera assembly 40 .

[0084] By using the embodiment of the present disclosure, the camera assembly 40 is powered by the wireless power supply module 50, which does not require cumbersome line connections, improves the convenience of installation and use, and reduces line connections, thereby reducing safety hazards caused by line aging, damage or improper operation, such as electric shock, short circuit, etc., especially when the installation space is connected to the storage space, there is a possibility that some cold air condenses into water or frost, which can effectively improve safety. In addition, the wireless power supply module 50 can usually be used to charge multiple devices. If there are other devices that need to be powered, only the corresponding receiver needs to be added, and there is no need to make a separate wired connection for each device, which can effectively improve flexibility.

[0085] Optionally, there are two wireless power supply modules 50 , one of which is connected to the transmission belt 43 , and the wireless power supply module 50 is used to supply power to the camera 44 separately.

[0086] In this way, by connecting the wireless power supply module 50 to the transmission belt 43, the wireless power supply module 50 connected to the transmission belt 43 can move with the movement of the transmission belt 43, ensuring that the camera 44 can obtain a stable power supply at any position. This avoids the problem of power interruption or shortage due to the change of the position of the camera 44. In addition, two wireless power supply modules 50 are set, one of which supplies power to the fixed device and the other supplies power to the camera 44, which can effectively improve the power supply stability of the wireless power supply module 50 and avoid the situation where the refrigerator door assembly cannot operate stably due to unstable power supply.
