Description

Technical Field

[0001] This invention belongs to the field of vehicle-mounted public facilities technology, and in particular relates to a vehicle-mounted refrigerator that can support unmanned vending functions. Background Technology

[0002] Traditional vehicle-mounted refrigerators only have cooling / insulation functions and are mostly used for personal refrigeration inside vehicles. They lack the ability to sell goods, manage inventory, facilitate mobile payments, and automatically open doors. Existing unmanned vending machines are mostly fixed-location cabinets, which are large in size, consume a lot of power, and are not suitable for the bumpy rides and power supply environments of vehicles. Therefore, they cannot be deployed on mobile vehicles such as ride-hailing vehicles, logistics vehicles, passenger vehicles, and RVs.

[0003] While some smart refrigerators support control via mobile app, they lack features such as a lightweight WeChat mini-program entry point, Bluetooth near-field communication, independent compartment locking, and closed-loop verification of retrieval and placement actions. This can lead to issues like unpaid door opening, failure to record retrievals, inaccurate inventory, and communication interruptions, making it difficult to meet the needs of safe, stable, and convenient unmanned vending in mobile vehicle scenarios.

[0004] Therefore, the industry urgently needs a vehicle-mounted unmanned vending refrigerator that is compatible with vehicle power supply and installation, relies on WeChat mini-programs, Bluetooth near-field interaction, has independent compartment control, traceable retrieval and placement actions, and automatic door opening with payment closed loop.

However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0017] It should also be noted that, in order to avoid obscuring the invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the invention are shown in the accompanying drawings, while other details that are not closely related to the invention are omitted. Specific implementation method one: See Figure 1 , Figure 2 , Figure 4 As shown, this specific embodiment adopts the following technical solution: It includes a housing 1, a semiconductor intelligent component 2, a wireless main control module 3, and a multi-compartment independent lockable storage component 4. The semiconductor intelligent component 2 is installed at the bottom of the housing 1, and the wireless main control module 3 is installed at the top of the housing 1. Several multi-compartment independent lockable storage components 4 are installed inside the housing 1. Each multi-compartment independent lockable storage component 4 consists of an independent storage chamber 9, a transparent sealing door 6, and an electromagnetic lock 8. The left side edge of the independent storage chamber 9 is connected to the transparent sealing door 6 through a spring hinge 5, and the right side of the independent storage chamber 9 is inlaid with the electromagnetic lock 8. The electromagnetic lock 8 is attracted to the metal part 7 on the edge of the transparent sealing door 6 to achieve the sealing closure of the transparent sealing door 6.

[0019] The independent storage chambers 9 inside the box are each equipped with a unique number, an independent door and an electronic lock; The main control unit is connected to the refrigeration control module, Bluetooth communication module, power management module, independent locking mechanism, and commodity detection module respectively; the Bluetooth communication module establishes a near-field connection with the user's mobile phone WeChat mini program to receive commodity selection instructions, transmit warehouse status, commodity retrieval and placement actions, and inventory information; The WeChat mini-program server completes product display, order generation, payment verification, instruction issuance, and transaction recording; The power management module is compatible with vehicle DC12V / 24V input, Type-C or USB, and features low voltage protection, reverse connection protection, regulated output, and sleep / wake-up functions. The product detection module uses a magnetic door switch to identify the opening and closing of the warehouse door and the actions of picking up and putting down products, and uploads the information to the main control unit. The main control unit verifies the legality of the command and drives the corresponding electronic lock to unlock, allowing the door to be opened manually. After the magnetic door and photoelectric sensors detect that the door is open and the product is taken out, they record the action and timestamp, and transmit the data back to the mini-program via Bluetooth. After the warehouse door is closed, it automatically locks, and the mini-program marks the transaction as complete and synchronizes the inventory.

[0020] In addition, the enclosure adopts a vehicle-mounted shock-resistant structure, with 4-8 independent compartments inside, each labeled with a number and equipped with an electronic door lock and magnetic door switch; the cooling module uses semiconductor cooling, with a temperature range of -2℃ to 15℃; the main control unit uses a 32-bit MCU; Bluetooth is BLE 5.0; power management supports DC12V / 24V and Type-C vehicle power input, compatible with vehicle cigarette lighters and constant power supply. The WeChat mini-program provides functions for product display, order creation, payment verification, transaction records, and inventory synchronization. Each compartment is independently controlled; after successful payment, only the corresponding numbered compartment door opens, and it automatically locks and updates its status after the goods are retrieved.

[0021] This specific implementation method includes the following steps: S1. The WeChat mini program displays products and receives user purchase instructions; S2. Generate the order and complete the payment verification; S3. Send the corresponding compartment unlocking command to the vehicle refrigerator main control unit via Bluetooth; S4. The main control unit drives the electronic lock of the corresponding numbered compartment to open; S5. The product detection module identifies and records picking and placing actions; S6, Bluetooth transmits status back to the mini-program, completing transaction and inventory updates. Specific Implementation Method Two: See Figure 1 , Figure 3 , Figure 4As shown, the difference between this specific embodiment and Specific Embodiment 1 is that it also includes a visual recognition module, an AI recognition module, and a payment settlement module; the visual recognition module, AI recognition module, and payment settlement module are all connected to the main control unit, and several cameras inside the refrigerator interact with the mobile phone through the main control unit, and the visual recognition module and AI recognition module interact to recognize the images from the cameras.

[0023] The cameras are high-definition wide-angle cameras, with no fewer than two, which are respectively arranged on the top and side of the refrigerator's inner liner to achieve shooting without blind spots.

[0024] The AI ​​recognition unit identifies the addition or removal of goods and changes in their location by comparing images before and after the door is opened, and completes accurate classification of goods through a deep learning model.

[0025] The visual recognition module is suitable for sales scenarios where the products have distinct shapes and relatively fixed placement.

[0026] This specific implementation method includes the following steps: S1. The WeChat mini program displays the products and receives user commands to open the door. S2. Send the corresponding compartment unlocking command to the vehicle refrigerator main control unit via Bluetooth; S3. The main control unit drives the electronic lock of the corresponding numbered compartment to open; S4. After the door is opened, the combination of visual recognition module and AI recognition module identifies the type and quantity of items taken by the user; S5 transmits the status back to the mini-program via Bluetooth, and the payment and settlement module generates an order.

[0027] S6. After the door is closed, it automatically locks and triggers visual recognition and automatic settlement, and updates the inventory.

[0028] In this specific embodiment, multiple high-definition wide-angle cameras are installed inside the refrigerator to achieve full-view coverage; by capturing a baseline image before the door is opened and an image of the goods after the door is closed, the types and quantities of goods are identified through AI image comparison and deep learning algorithms; users scan the code to open the door and take the goods, and the transaction is automatically settled after the door is closed, completing the unmanned vending.

[0029] This specific implementation method uses multiple cameras to capture images from all angles, ensuring complete image information; it employs before-and-after door opening comparison combined with AI deep learning, resulting in accurate product recognition and a low misjudgment rate; it requires no separate warehousing or packaging modifications, boasting a simple structure and low cost; and it is adaptable to in-vehicle environments, enabling truly unattended automated vending. Specific implementation method three: See Figures 1-5As shown, in this specific embodiment, the multi-compartment independent lockable storage component 4 is replaced with an independent box-type storage component 41.
