It should be understood that the terms used in this manner are interchangeable where appropriate to describe the embodiments of the present disclosure herein. In addition, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[0023] Unless otherwise stated, the term "plurality" means two or more.

[0024] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B means: A or B.

[0025] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0026] Combine Figure 1 As shown, the embodiment of the present disclosure provides a delivery control method, including:

[0027] Step S101. Transfer the goods to the delivery device according to the number of personnel;

[0028] Step S102: Control the delivery device to move to the set target location.

[0029] The delivery control method provided by the embodiment of the present disclosure can match the corresponding amount of goods based on the number of people, and move the delivery device to the target location, so as to automatically deliver the required amount of goods to the target location, provide convenience to users, and deliver the required amount at one time, thereby improving delivery efficiency.

[0030] Optionally, the goods are moved to the delivery device according to the number of people, including: controlling the delivery device to move the goods to the transmission device according to the number of people, and controlling the transmission device to move the goods to the delivery device.

[0031] Optionally, controlling the delivery device to move goods to the transport device based on the number of people includes: matching the number of goods to the number of people, so that the number of goods transferred to the delivery device is equal to the number of people. Optionally, the target location is detected by a human detection device, such as a camera or infrared sensor, which performs facial recognition on people, or an infrared sensor. If three people are detected at the target location, three delivery devices are controlled to move three goods, such as three bottles of mineral water, to the delivery device. This allows for automatic identification of user demand based on the number of people, improving the accuracy of demand acquisition.

[0032] Optionally, before controlling the delivery device to move to the target location, the method further includes: controlling the delivery device to shut down.

[0033] Optionally, controlling the delivery device to shut down includes controlling the delivery device to shut down when the number of goods transferred to the delivery device is equal to the number of personnel. Alternatively, if the number of personnel is three and the number of goods transferred to the delivery device is also three bottles of mineral water, the delivery device is shut down and controlled to move toward the target location. This improves delivery efficiency.

[0034] Optionally, the delivery control method further includes: when the delivery device reaches the target location, controlling the delivery device to open, so that it is convenient for the user to take out the goods; and controlling the delivery device to close and return to the initial position when conditions are met.

[0035] Optionally, the conditions are met including: detecting that goods have left the delivery device; and / or the delivery device is turned on for a set period of time.

[0036] Optionally, after the delivery device reaches the target location and detects that goods have left the delivery device, the delivery device is controlled to shut down and return to its initial position. Optionally, after the delivery device reaches the target location, the delivery device is controlled to shut down and return to its initial position after a set time has passed. This can save power consumption of the delivery device.

[0037] Optionally, controlling the delivery device to close includes: controlling a cargo hold of the delivery device to descend so that the delivery device is closed. Optionally, controlling the cargo hold of the delivery device to ascend so that the delivery device is opened.

[0038] Optionally, a pressure sensor is installed in the delivery device's cargo hold. When the pressure increases, it indicates that goods have been received, and when the pressure decreases, it indicates that goods have been removed. The pressure sensor detects changes in pressure to determine the number of goods received or removed. Different weights of goods can also correspond to different pressure values. For example, a pressure range of 4N to 6N can be set to represent one bottle of water, 9N to 11N to represent two bottles of water, 14N to 16N to represent three bottles of water, and 0.4N to 0.6N to represent one loaf of bread. If the pressure sensor detects an increase of 15N in the cargo hold pressure, it determines that three bottles of water have been received. If the pressure sensor detects a decrease of 15N in the cargo hold pressure, it determines that three bottles of water have been removed. This improves the accuracy of determining the number of goods entering and leaving the cargo hold.

[0039] Optionally, the target position is a set coordinate value, such as a coordinate value of 1 meter near the dining table, a coordinate value of 0.5 meters near the sofa, or a coordinate value of 0.5 meters near the bed.

[0040] The delivery control method provided by the embodiment of the present disclosure can match the corresponding amount of goods based on the number of people, and move to the target location through the delivery device. It can automatically deliver the required amount of goods to the target location without the user issuing a control command, providing convenience to the user, and at the same time deliver the required amount at one time, thereby improving delivery efficiency and enhancing user experience.

[0041] In practical applications, the delivery device is set at the bottom of the refrigerator, such as Figure 2 , which is a schematic diagram of the cooperation between the refrigerator and the delivery device, including the delivery device 4, the refrigerator 1, the refrigerator display 2, and the refrigerator handle 3.

[0042] like Figure 3 The figure shows a front view of a refrigerator with its door open and the delivery mechanism in operation. Refrigerator 1 is equipped with multiple delivery mechanisms, each comprising a first motor 16, a support plate 1a, a partition 1b, and a coil spring 1c. The delivery mechanisms are divided into two groups, each secured in parallel and spaced apart from the bottom up within the refrigerator, leaving a channel in the middle for delivery. Partitions 1b are attached to support plate 1a to form a delivery lane. Goods are sorted and placed on the delivery lanes. Coil springs 1c are installed on the delivery lanes, one for each lane, with a pitch tailored to accommodate the goods.

[0043] like Figure 4 The figure shows a side view of the refrigerator and delivery device in cooperation. The delivery device has a first motor 16. The refrigerator 1 is also equipped with multiple conveying devices, including a second motor 17 and a conveyor belt 18. Each first motor 16 rotates a corresponding coil spring 1c, pushing the cargo away from the first motor 16, causing the cargo on the cargo aisle to fall onto the corresponding conveyor belt 18. The second motor 17 rotates the corresponding conveyor belt 18, which then transports the cargo to the delivery aisle between the two delivery devices. The cargo then falls from the delivery aisle into the raised cargo hold 10 of the delivery device 4.

[0044] like Figure 5The figure is a cross-sectional view of the delivery device with the lid open. The delivery device 4 includes a running drive wheel 5, a box body 6 and a box lid 7. The running drive wheel 5 is arranged on the lower surface of the bottom of the box body 6. Each running drive wheel 5 is driven by a motor; the box lid 7 is rotatably connected to the box body 6 through a rotating shaft 8. The box lid 7 is a double-door type. A first limit card 7a is provided on the box lid 7 to limit the rising height of the cargo hold 10; a lifting device is provided inside the box body 6. The lifting device includes a screw rod 11 and a fixing rod 12. Movable frame 13. One end of the screw rod 11 is fixed to the bottom of the box body 6 through a bearing 14. The stepping motor 15 drives the screw rod 11 to rotate. The screw rod 11 is passed through the movable frame 13 through a nut 13a. The fixed rod 12 is passed through the movable frame 13. One end of the fixed rod 12 is fixedly connected to the bottom of the box body 6, and the other end is provided with a second limit card 12a for limiting the rising height of the movable frame 13. One end of the cargo bin rod 10a is fixedly connected to the cargo bin 10, and the other end is fixed to the movable frame 13.

[0045] like Figure 6 The figure shows a cross-sectional view of the delivery device in a closed state of the box cover. An electronic lock 9 is provided on the box cover 7. The top of the cargo compartment 10 is lowered into the box body 6. When the box cover 7 is closed, the electronic lock 9 is locked.

[0046] Alternatively, if the number of people is detected as three, the first motors 16 corresponding to the three dispensing devices are controlled to rotate the corresponding coil springs 1c, simultaneously pushing the goods, for example, three bottles of mineral water, toward the corresponding conveyor belt 18. Simultaneously, the electronic lock 9 opens, and the stepper motor 15 reverses, driving the movable frame 13 and the cargo hold rod 10a upward, raising the cargo hold 10. When the movable frame 13 reaches the second stop 12a on the fixed rod 12, the top of the cargo hold 10 now contacts the first stop 7a of the lid 7, and the stepper motor 15 stops reversing, halting the rise of the cargo hold 10. When the three bottles of mineral water fall onto the corresponding conveyor belt 18, the corresponding second motor 17 rotates the conveyor belt 18, transporting the three bottles of mineral water to the dispensing channel between the two dispensing devices. The mineral water then falls from the dispensing channel into the raised cargo hold 10 of the delivery device 4. The cargo hold detects a pressure value within the range of 14N to 16N through the pressure sensor, confirming that the three bottles of mineral water have been received.

[0047] Optionally, according to multiple tests, the time taken for the cargo hold to rise is 2 seconds, and the time taken for transferring cargo to the cargo hold is 5 seconds.

[0048] Optionally, after the cargo warehouse 10 receives 3 bottles of mineral water, the stepper motor 15 is controlled to operate to drive the movable frame 13 and the cargo warehouse rod 10a to move and make the cargo warehouse 10 descend. When the movable frame 13 descends to the bottom of the box body 6, the stepper motor 15 stops running. At this time, the cargo warehouse 10 is lowered into the box body 6, the box cover 7 is closed, the electronic lock 9 is locked, and the delivery device is closed.

[0049] Optionally, after the delivery device 4 receives three bottles of mineral water and shuts down, it is controlled to move toward a predetermined target location, such as a sofa. When the delivery device 4 reaches the target location, the electronic lock 9 is unlocked, and the stepper motor 15 reverses to drive the movable frame 13 and the cargo compartment rod 10a, causing the cargo compartment 10 to rise. When the movable frame 13 reaches the second stop 12a on the fixed rod 12, the top of the cargo compartment 10 contacts the first stop 7a on the lid 7, and the cargo compartment 10 stops rising, presenting the three bottles of mineral water to the user. When the cargo compartment pressure sensor detects a decrease in pressure between 14N and 16N, the three bottles of mineral water are deemed to have been removed. Alternatively, after a predetermined time, such as 10 minutes, the stepper motor 15 is controlled to operate, driving the movable frame 13 and the cargo compartment rod 10a to lower the cargo compartment 10. When the movable frame 13 reaches the bottom of the container 6, the cargo compartment 10 is now inside the container 6, the stepper motor 15 stops, the lid 7 closes, the electronic lock 9 is locked, and the delivery device is closed. The delivery mechanism is then controlled to return to its initial position, at the bottom of the refrigerator. This allows the refrigerator to deliver a matching quantity of bottled water and other goods to the designated destination, eliminating the need for user control commands. The delivery mechanism automatically delivers the goods to the user, completing the required quantity in one go. This improves delivery efficiency, expands the refrigerator's functionality, makes it more intelligent, and enhances the user experience.

[0050] Optionally, a photoelectric switch is provided in the cargo warehouse 10 to detect whether cargo has been received or taken away from the cargo warehouse.

[0051] Optionally, during the process of the delivery device moving toward the target location, if the distance between the delivery device and the target location is less than or equal to a first set threshold, the delivery device is controlled to stop moving. Optionally, the first set threshold is 0.5 meters.

[0052] Optionally, the delivery device is battery powered.

[0053] Optionally, the delivery device is provided with a running drive wheel and a drive motor, which can enable the delivery device to move on a plane. The front end and side of the delivery device are also provided with a camera device, which can obtain road information in real time by collecting graphics and identifying them. If obstacles such as steps are encountered, the controller controls the delivery device to turn or stop running to prevent collision or falling. At the same time, a radar ultrasonic sensor is also provided to detect the distance between the delivery device and surrounding objects when it moves. The running drive wheel of the delivery device is provided with a photoelectric encoder disk, which can detect and control the wheel speed to achieve positioning and path planning.

[0054] Optionally, facial recognition is performed using a camera or infrared sensor. If three people are detected at a target location, the refrigerator's three delivery devices are controlled to move the corresponding goods, such as three bottles of mineral water, via a conveyor device to a delivery device. The delivery device is then controlled to deliver the three bottles of mineral water to the target location, such as a dining table. When the delivery device arrives at the dining table, it is activated, allowing each user to quickly and conveniently receive their mineral water. This allows for the delivery of the required quantity of goods to the user at once, bringing convenience to the user, improving delivery efficiency, and making the refrigerator more intelligent.

[0055] Optionally, after the user removes three bottles of mineral water from the delivery device, or after a set time, for example, 10 minutes, the delivery device shuts down and returns to its original position, i.e., the bottom of the refrigerator. This prevents the delivery device from being in the delivery state for extended periods, which could lead to excessive power consumption. By returning the delivery device to its original position promptly, electricity can be saved.
