[0002] As an important piece of equipment for car travel and outdoor activities, in-vehicle refrigerators and warmers have made significant progress in recent years in terms of technology, market and application.

[0003] Existing vehicle-mounted refrigerators and heaters mainly provide a temperature-controllable vehicle-mounted refrigerator and heater. For example, the invention patent application with patent publication number CN118596975A discloses a dual-temperature zone vehicle-mounted refrigerator and heater, which adds an independent privacy storage space. The privacy storage space and the main space can achieve different temperatures, thus realizing a dual-temperature zone vehicle-mounted refrigerator and heater.

[0004] However, when items are placed in the car's refrigerator / warmer, users cannot record the names and expiration dates of the items, nor are there any reminders. As a result, items easily expire, leading to waste. Summary of the Invention

[0005] This invention provides a method, device, electronic device, and storage medium for recording and reminding items placed in a vehicle-mounted refrigerator / warmer. The aim is to upgrade the vehicle-mounted refrigerator / warmer from "simple storage" to "intelligent management" by recording items placed in the refrigerator / warmer and reminding them of their expiration dates. The refrigerator / warmer can also dynamically adjust the temperature according to the dynamic changes in the storage and retrieval of items to achieve the best storage effect.

[0006] To achieve the above objectives, this invention proposes a recording and reminder method for an in-vehicle refrigerator / warmer box, used in an electronic device. The refrigerator / warmer box includes a refrigerator box and a warmer box. The method includes... The information of the items is collected by the display screens set on the cold box or the warm box, and the information of different items in the cold box or the warm box is recorded. The item information includes item code, item name, item type, item quantity, production date and shelf life. Based on the different item information inside the cold box or warm box, an item storage list is generated; Calculate the expiration date of different items based on the production date and shelf life of the items in the item storage list, and add the production date and shelf life together to get the expiration date; Get the current date; The expiration date is compared with the current date. If the expiration date is greater than the current date and the number of days between the expiration date and the current date is between 1 and 7, a warning message is issued to indicate that the expiration date is imminent. Obtain the optimal storage temperature values ​​for different item types; The item information and the warning information are synchronized to the vehicle's infotainment screen via Bluetooth, and the vehicle's infotainment screen then synchronizes the item information and the warning information to the mobile app via Bluetooth.

[0007] In some embodiments, recording information about different items inside the cold box or warm box specifically involves: obtaining item information by scanning the barcode of the item through the acquisition device in the display screen, or manually inputting item information by touching the screen of the display screen.

[0008] In some embodiments, comparing the expiration date with the current date and issuing a warning message when the expiration date is greater than the current date and the number of days between the expiration date and the current date is equal to 1 to 7, specifically involves: determining the warning type when the expiration date is greater than the current date and the number of days between the expiration date and the current date is equal to 1 to 7; and determining the urgency of the warning based on the warning type, wherein the warning type includes general warning and emergency warning.

[0009] In some embodiments, when the expiration date is greater than the current date and the number of days between the expiration date and the current date is equal to 2 to 7, the warning type is a general warning; When the expiration date is greater than the current date and the number of days between the expiration date and the current date is equal to 1, the warning type is an emergency warning.

[0010] In some embodiments, the method further includes, when the user takes out an item, collecting the item information of the item taken out by the user through the display screens respectively set on the cold box or the warm box, and deleting the item information of the item taken out by the user from the item storage list or modifying the quantity of the item taken out by the user.

[0011] In some embodiments, the temperature of the cold box or warm box is dynamically adjusted according to the dynamic changes in the storage and retrieval of items. The highest and lowest optimal storage temperature values ​​of the items currently stored in the cold box or warm box are determined. The temperature difference between the highest and lowest optimal storage temperature values ​​is used as the upper limit adjustment difference and lower limit adjustment difference of the current temperature. The upper limit temperature adjustment value and lower limit temperature adjustment value are then determined.

[0012] In some embodiments, the storage priority of items in the cold box or warm box is determined, the optimal storage temperature value of the highest priority item is determined, when the optimal storage temperature value of the highest priority item is close to the upper limit temperature adjustment value, the upper limit temperature adjustment value is determined to be the temperature adjustment value, and when the optimal storage temperature value of the highest priority item is close to the lower limit temperature adjustment value, the lower limit temperature adjustment value is determined to be the temperature adjustment value.

[0013] The present invention also proposes a recording and reminder device for a vehicle-mounted refrigerator / warmer, comprising: The data collection unit is used to collect item information. A recording unit is used to record information about different items inside the cold box or warm box; The generation unit is used to generate an item storage list based on the different item information inside the cold box or warm box; The calculation unit is used to calculate the expiration date of different items based on the production date and shelf life of the items in the item storage list, and to add the production date and shelf life to obtain the expiration date; The first acquisition unit is used to acquire the current date; The early warning unit is used to compare the expiration date with the current date. When the expiration date is greater than the current date and the number of days between the expiration date and the current date is equal to 1 to 7, an early warning message is issued to indicate that the expiration date is imminent. The second acquisition unit is used to acquire the optimal storage temperature value for different types of items. A communication unit is used to synchronize the item information and the warning information to the vehicle screen via Bluetooth, and the vehicle screen synchronizes the item information and the warning information to a mobile APP via Bluetooth.

[0014] The present invention also proposes an electronic device comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the computer program, when executed by the processor, implements the steps of the recording and reminder method for an in-vehicle refrigerator / heater box as described in any one of claims 1 to 7.

[0015] The present invention also proposes a storage medium storing a computer program, which, when executed by a processor, implements the steps of the recording and reminder method for an in-vehicle refrigerator / warmer box as described in any one of claims 1 to 7.

[0016] The invention proposes a recording and reminder method for in-vehicle refrigerators and warmers. This method collects item information via a display screen, records information about different items inside the refrigerator or warmer, generates an item storage list, calculates the expiration date of different items based on the production date and shelf life in the item storage list, adds the production date and shelf life to obtain the expiration date, compares the expiration date with the current date, and issues a warning message when the expiration date is greater than the current date and the difference between the expiration date and the current date is between 1 and 7 days, indicating that the item is about to expire. This method records the items placed in the in-vehicle refrigerator / warmer and provides expiration reminders. The in-vehicle refrigerator / warmer is thus transformed from a "simple" system into a system that records and reminds users of expiration dates. The storage system has been upgraded to a "smart manager," simultaneously synchronizing item information and expiration date warnings to the vehicle's infotainment screen and mobile app. Users can view the item information and expiration date warnings in the vehicle's refrigerator / warmer in real time via these devices. Furthermore, this invention obtains the optimal storage temperature for different item types and uses the temperature difference between the highest and lowest optimal storage temperatures as the upper and lower limit adjustment values ​​for the current temperature. This allows for dynamic temperature adjustment based on changes in item storage and retrieval, achieving optimal storage results and broadening its applicability. Attached Figure Description

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0022] See Figure 1 An embodiment of the recording and reminder method for the vehicle-mounted refrigerator / heater box of the present invention is proposed, comprising: Step S101: Collect item information through the display screens set on the cold box or the warm box respectively, and record the different item information in the cold box or the warm box. The item information includes item code, item name, item type, item quantity, production date and shelf life.

[0023] In this step, recording the information of different items inside the cold box or warm box specifically involves: scanning the barcode of the item using the acquisition device in the display screen to obtain the item information, or manually inputting the item information via touch screen on the display screen.

[0024] In this step, an RFID scanner can be used as the data collection device.

[0025] In this step, the cold and warm box includes a cold box and a warm box. The cold box and the warm box are two independent integrated spaces. The cold and warm areas are completely independent and separated. The lid has cold and warm markings. The lid of the cold box or the warm box is independent and is equipped with a display screen on the top of the lid. The display screen can be connected to the vehicle's infotainment screen via Bluetooth. The mobile APP can remotely control the functions in the vehicle.

[0026] In this step, the main information fields recorded are: Item Code: Unique identifier, Item Name: Name of the product or medicine, Item Type: Item category (e.g., fruit, fever reducer, milk), Item Quantity: Quantity currently stored in the box, Production Date / Shelf Life: Used to monitor items nearing their expiration date and trigger alerts.

[0027] Step S102: Generate an item storage list based on the different item information in the cold box or warm box.

[0028] Example of data storage for item information in a cold storage container: Item code: "COLD-001" Item Name: Iced Black Tea Item type: "Beverage" Item quantity: 1 Production Date: March 1, 2024 Shelf life: 6 months Storage temperature: 8℃ "Container Number": "COLD-1".

[0029] Example of data storage for item information in an incubator: Item code: "HOT-001" Item Name: Milk Item type: Dairy products Item quantity: 2 Production Date: June 15, 2024 Shelf life: 30 days Storage temperature: 15℃ "Container Number": "HOT-1".

[0030] The acquired item information is arranged according to preset rules, forming a structured table displayed on the screen, and synchronized to the vehicle's infotainment system and mobile app.

[0031]

[0032] Step S103: Calculate the expiration date of different items based on the production date and shelf life of the items in the item storage list, and add the production date and shelf life together to get the expiration date.

[0033] In this step, the shelf life is expressed in days (e.g., "Shelf life: 30 days") or in months (e.g., "Shelf life: 6 months").

[0034] The specific calculation method is as follows: Expiry date = Production date + Shelf life (Year-end and month-end dates need to be handled): Example: Production date: 2024-06-01, Shelf life: 30 days, Expiry date: 2024-07-01.

[0035] Expiry date = Production date + Shelf life in months (Year-end dates and end-of-month dates need to be handled): Example: Production date: 2024-01-31, Shelf life: 1 month, Expiry date: 2024-02-29 (automatically calculates the number of days in 2 months).

[0036] The calculated expiration dates are arranged according to preset rules, synchronized to a structured table in the item storage list, displayed on the screen, and also synchronized to the vehicle's infotainment system and mobile app.

[0037]

[0038] Step S104: Get the current date, and get the year, month and day of the current date.

[0039] Step S105: Compare the expiration date with the current date. When the expiration date is greater than the current date and the number of days between the expiration date and the current date is equal to 1 to 7, issue a warning message to indicate that the expiration is imminent.

[0040] In this step, the judgment condition is: if (expiration date > current date) and (difference in days ∈ [1, 7]) → trigger warning.

[0041] The warning information includes the item code, item name, and remaining days. Example of a warning: Warning message: Milk (HOT-001) will expire in 1 day.

[0042] In this step, the remaining days are arranged according to preset rules, synchronized to a structured table in the item storage list, displayed on the screen, and also synchronized to the vehicle's infotainment system and mobile app.

[0043] In this step, when the expiration date is greater than the current date and the number of days between the expiration date and the current date is equal to 1 to 7, the warning type is determined, and the urgency of the warning is determined based on the warning type. The warning types include general warnings and emergency warnings.

[0044] In this step, when the expiration date is greater than the current date and the number of days between the expiration date and the current date is equal to 2 to 7, the warning type is a general warning; In this step, when the expiration date is greater than the current date and the number of days between the expiration date and the current date is equal to 1, the warning type is an emergency warning.

[0045] Warning types can be displayed in different ways:

[0046] Step S106: Obtain the optimal storage temperature value for different types of items.

[0047] See Figure 2Step S107: The item information and the warning information are synchronized to the vehicle screen via Bluetooth connection, and the vehicle screen synchronizes the item information and the warning information to the mobile APP via Bluetooth connection.

[0048] In this step, the mobile app can sync data to the cloud for backup.

[0049] In some embodiments, the user can set the temperature of the warm / cold box as needed or automatically adjust the temperature according to the temperature required by the items currently stored.

[0050] Example of in-vehicle infotainment screen interface:

[0051] See Figure 3 The recording and reminder method of the vehicle-mounted refrigerator / heater box of the present invention further includes, when the user takes out an item, collecting the item information of the item taken out by the user through the display screens respectively set on the refrigerator or the heater box, and deleting the item information of the item taken out by the user or modifying the quantity of the item taken out by the user in the item storage list.

[0052] In this step, when retrieving an item, if the quantity of the retrieved item equals the current item inventory, the item is deleted from the item list; if the quantity of the retrieved item is less than the current item inventory, the item quantity is reduced by the corresponding value.

[0053] In one embodiment, the temperature of the cold box or warm box is dynamically adjusted according to the dynamic changes in the storage and retrieval of items. The highest and lowest optimal storage temperature values ​​of the items currently stored in the cold box or warm box are determined. The temperature difference between the highest and lowest optimal storage temperature values ​​is used as the upper limit adjustment difference and lower limit adjustment difference of the current temperature. The upper limit temperature adjustment value and lower limit temperature adjustment value are then determined.

[0054] In one embodiment, the global optimal temperature range is calculated based on the temperature requirements of all items in the box, and the highest and lowest optimal storage temperature values ​​of the currently stored items are taken as the highest and lowest values ​​of the temperature range.

[0055] In one embodiment, the temperature is dynamically adjusted based on the dynamic changes in the storage and retrieval of items and the global optimal temperature range. When a new item is added, the temperature range is recalculated. If the new item requires a narrower range, the temperature range is adjusted immediately. When an item is removed, if the remaining items allow for a wider temperature range, the temperature range is adjusted in a stepwise manner (changing by 1°C every 30 minutes to avoid drastic fluctuations). When the box is empty, it switches to energy-saving mode, and the cold or warm box restores its default temperature.

[0056] In one embodiment, the upper limit temperature adjustment value is determined by adding the current temperature and the temperature difference, and the lower limit temperature adjustment value is determined by subtracting the current temperature and the temperature difference.

[0057] In one embodiment, the frequency of opening and closing of the cold box or warm box within a preset time period is detected. When the frequency of opening and closing exceeds the preset normal frequency, a dynamic compensation mechanism is implemented for the temperature difference, automatically adjusting the temperature difference, calculating the dynamic compensation value according to preset rules, and adding the temperature difference and the dynamic compensation value to obtain a new temperature difference, thereby obtaining a new upper limit temperature adjustment value and a lower limit temperature adjustment value.

[0058] In one embodiment, the storage priority of items in the cold box or warm box is determined, the optimal storage temperature value of the highest priority item is determined, when the optimal storage temperature value of the highest priority item is close to the upper limit temperature adjustment value, the upper limit temperature adjustment value is determined to be the temperature adjustment value, and when the optimal storage temperature value of the highest priority item is close to the lower limit temperature adjustment value, the lower limit temperature adjustment value is determined to be the temperature adjustment value.

[0059]

[0060] It should be noted that, provided there are no contradictions or conflicts between the above embodiments of the recording and reminder method for the vehicle-mounted refrigerator / heater box of this application, the above embodiments can be arbitrarily combined or combined to form new embodiments.

[0061] See Figure 2 The present invention further proposes a recording and reminder device for a vehicle-mounted refrigerator / warmer, comprising: The data collection unit is used to collect item information. A recording unit is used to record information about different items inside the cold box or warm box; The generation unit is used to generate an item storage list based on the different item information inside the cold box or warm box; The calculation unit is used to calculate the expiration date of different items based on the production date and shelf life of the items in the item storage list, and to add the production date and shelf life to obtain the expiration date; The first acquisition unit is used to acquire the current date; The early warning unit is used to compare the expiration date with the current date. When the expiration date is greater than the current date and the number of days between the expiration date and the current date is equal to 1 to 7, an early warning message is issued to indicate that the expiration date is imminent. The second acquisition unit is used to acquire the optimal storage temperature value for different types of items. A communication unit is used to synchronize the item information and the warning information to the vehicle screen via Bluetooth, and the vehicle screen synchronizes the item information and the warning information to a mobile APP via Bluetooth.

[0062] This invention proposes a recording and reminder device for a vehicle-mounted hot and cold box, which also includes a temperature control unit for adjusting the temperature.

[0063] This invention proposes a recording and reminder system for an in-vehicle refrigerator / warmer, including a recording and reminder device, an in-vehicle infotainment screen, and a mobile app, wherein the recording and reminder device is communicatively connected to the in-vehicle infotainment screen and the mobile app.

[0064] See Figure 4 This invention proposes a method for recording and alerting users of an in-vehicle refrigerator / heater. The system can operate normally under any vehicle condition and is disabled by default at the factory, avoiding unnecessary resource waste. There are two activation methods: local activation and remote activation. Local activation involves the user clicking the soft switch for the recording and alerting device on the vehicle's infotainment screen. Clicking this will bring up an interface with soft switches for turning the refrigerator and heater on and off, and the user can also set the temperatures maintained by the refrigerator and heater. Remote activation involves the user clicking the soft switch for the refrigerator / heater recording and alerting device via a mobile app. Clicking this will bring up an interface with soft switches for turning the refrigerator and heater on and off, and the user can also set the temperatures maintained by the refrigerator and heater. Once the cooler / warmer is opened, it immediately powers on and begins operation. Users can scan the barcode of an item on the corresponding display screen on the cooler / warmer lid. Successful scanning will immediately display the item's name and expiration date. For items that cannot be scanned, users can manually enter the item's name and expiration date on the display screen. The data uploaded to the display screen will be immediately transmitted to the vehicle's infotainment system, which will then upload it to the mobile app. After removing an item, the user can delete it from the list on the display screen / vehicle infotainment system / mobile app. When an item is about to expire in one day, the display screen / vehicle infotainment system / mobile app will remind the user to use it as soon as possible. Closing is done in the same way as opening: local and remote closing. Local closing involves the user clicking the soft switch to turn off the recording and reminder device on the vehicle infotainment system, while remote closing involves clicking the soft switch to turn off the recording and reminder device on the mobile app.

[0065] The usage process of this invention includes the following steps: 101: The user selects to activate the cold box and warm box via the vehicle's infotainment system / mobile app, and sets a constant temperature for both. The system is then officially activated. 102: Users scan the barcode of the item to be placed on the display screen on the cooler / warmer box / manually enter the name and shelf life of the item to be placed on the display screen; 103: The display screen of the refrigerator / warmer box will immediately save the information of the stored items and transmit the latest information to the vehicle's infotainment screen in real time via Bluetooth; 104: The vehicle's infotainment screen immediately saves the received item information and transmits it to the mobile app in real time, allowing users to view the item information via the screen / vehicle infotainment system / mobile app; 105: When an item has only 1 day left before its expiration date, the display screen / vehicle system / mobile app will send a pop-up reminder to the user that the item is about to expire; 106: Users can choose to turn off the cold box and warm box at any time via the vehicle system / mobile APP.

[0066] This invention proposes a recording and reminder method for a vehicle-mounted refrigerator / warmer, which has heating or heat preservation functions as well as the function of a refrigerator, and adds recording and reminder functions. Users can record the name of the item and its corresponding shelf life when putting it in. The system will remind the user when an item is about to expire. Users can also check the shelf life of items at any time through the refrigerator / warmer display screen, the vehicle's infotainment screen, and a mobile APP. Users can also view the list of items stored in the refrigerator / warmer in real time, which brings great convenience to users.
