The present disclosure claims priority of Chinese Patent Application No. 202410402318.6 filed on Apr. 3, 2024, the entire contents of which are hereby incorporated by reference in their entirety.

The present disclosure relates to the technical field of mobile portable refrigerators or heating boxes, and more specifically to a method of automatically opening and closing a door body of a refrigeration or heating box by recognizing user identity.

Currently, the takeaway industry is prevalent. There are many people working in this industry, and competition from multiple platforms has intensified. Along therewith, the platforms and customers have increased the demand for delivery of takeaways, and therefore, the takeaway deliverers have accelerated their work pace to meet the requirements and to increase the delivery volume, often leaving with the takeaway boxes opened and returning to find that takeaways have been stolen. Even worse, the takeaways are poisoned without anyone realizing it, which is a very high risk. Since it is difficult to rely on the takeaway deliverers themselves to take precautions, the market is calling for a mobile refrigerator or heating box with an automatic opening and closing door, so as to provide assistance to the takeaway deliverers and to effectively solve the potential food safety issues. In addition, a convenient and safe mobile refrigerator may be provided for a user who loves to travel, for preventing food spoilage caused by the user forgetting to close the door of the refrigerator or heating box.

Technical Effect

In the present disclosure, multiple sensors may be applied to obtain the user identity information, so as to ensure that the information is accurate. When the identity verification is complete, the logic control unit controls the circuit system to open the door body, such that the user can access the internal food, without the need of opening or closing the door body by him-/herself, while the system will conduct the control on its own. In this way, the user is free from the worry of forgetting to close the door body.

In order to illustrate the technical solutions in the embodiments of the present disclosure more clearly, the accompanying drawings to be used in the description of the embodiments will be briefly described below.

FIG. 1 is a block schematic diagram according to some embodiments of the present disclosure.

In order to make the technical problems solved by the present disclosure, and the technical solutions and beneficial effects brought by the present disclosure clearer and more understandable, the present disclosure is described in further detail hereinafter in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present disclosure and are not intended to limit the present disclosure.

Referring to FIG. 1 , a method of automatically opening and closing a door body of a refrigeration or heating box by recognizing a user identity, including the following operations.

S1, obtaining, by a logic control unit (Micro Controller Unit, MCU) of the refrigeration or heating box, user identity information based on information from an external sensor; S2, recognizing and determining, by the logic control unit, the user identity information to obtain a recognition result; in response to the recognition result being that the user identity information is not authorized, displaying, by a display screen of the refrigeration or heating box, an error prompt; S3, in response to the recognition result being that the user identity information is authorized, opening, by a control circuit system of the refrigeration or heating box, the door body.

In the present disclosure, multiple sensors may be applied to obtain the user identity information, so as to ensure that the information is accurate. When the identity verification is complete, the logic control unit controls the circuit system to open the door body, such that the user can access the internal food, without the need of opening or closing the door body by him-/herself, while the system will conduct the control on its own.
