[0035] The present invention provides a vehicle refrigerator and a control system thereof, which relates to the technical field of vehicle refrigerators, and can be specifically applied to solve the technical problems in the prior art that vehicle refrigerators are limited by power supply, have a single usage scenario, and are not convenient enough in the control mode of vehicle refrigerators and lack remote control. The present invention improves the portability and versatility of vehicle refrigerators, expands the control mode of vehicle refrigerators, can adapt to the usage requirements in different scenarios, and improves the comfort and convenience of outdoor travel. The following is a detailed description through specific embodiments.

[0036] In one embodiment of the present invention, a vehicle refrigerator may include a refrigerator body, a power supply interface, and a refrigerator control module. The refrigerator body can be detachably connected to the vehicle, so that it can be used in the vehicle and used outside the vehicle after being detached. The power supply interface can be provided on the refrigerator body, which adopts a universal power supply interface and can be adapted to the vehicle power supply port and the external power supply port, that is, the vehicle refrigerator can be powered by the vehicle power supply port in the vehicle, and can be powered by the external power supply port outside the vehicle. In this embodiment, the vehicle refrigerator is equipped with at least two power cords, one of which is a 12V vehicle power cord that can be connected to the vehicle power supply port; the other is a power cord equipped with an adapter, which can convert 220V to 12V for power supply, that is, the vehicle refrigerator is connected to the external power supply port for power supply, for example, outdoor V2L (Vehicle-to-Load) or outdoor battery is used for power supply. The refrigerator control module can be located on the refrigerator body and can be used to control the refrigerator body to work. In addition, the refrigerator control module can also be used to collect real-time working status information of the refrigerator body. In this embodiment, the refrigerator control module can, for example, control the opening / closing of the refrigerator door, the turning on / off of the power, the selection of temperature modes (such as soft freezing, cold drinks, mother and baby, and keeping warm), temperature adjustment (increase / decrease temperature value, set maximum / minimum / specified temperature), control the turning on / off of the sterilization function, and set the operating time after locking the vehicle, etc.

[0037] In one embodiment of the present invention, the vehicle refrigerator further includes a wireless communication module, which can be used to receive an external first operation instruction. In this embodiment, the wireless communication module can realize a short-range wireless communication connection with the client. The client sends the first operation instruction to the wireless communication module through a short-range wireless communication technology such as Bluetooth. The refrigerator control module controls the refrigerator body to perform a corresponding operation based on the first operation instruction. At the same time, the refrigerator control module can also send real-time working status information of the refrigerator body to the client through the wireless communication module.

[0038] In one embodiment of the present invention, the vehicle refrigerator further includes a wired communication module, which can be used to receive a second operation instruction of the vehicle. In this embodiment, the wired communication module can be connected to the vehicle through a LIN (Local Interconnect Network) bus, and can be used to receive the second operation instruction sent by the vehicle. The refrigerator control module controls the refrigerator body to perform a corresponding operation based on the second operation instruction. At the same time, the refrigerator control module can also send real-time working status information of the refrigerator body to the vehicle through the wired communication module.

[0039] In one embodiment of the present invention, the refrigerator control module can also be used to set the operating time of the refrigerator body according to the above-mentioned first operating instruction or the second operating instruction, and turn off the power supply to the refrigerator body after the timing ends.

[0040] See also Figure 1 In one embodiment of the present invention, the vehicle refrigerator is provided with a control panel, and the refrigerator control module can be electrically connected to the control panel. The control panel is provided with a physical button switch. When using the vehicle refrigerator, the user can adjust multiple functional parameters of the vehicle refrigerator through the physical button switch on the control panel. In this embodiment, the physical buttons of the control panel may include: a power switch, a refrigerator door switch, a cooling / heating switch, a temperature adjustment switch, and a temperature display screen.

[0041] In one embodiment of the present invention, the adjustable working parameters of the car refrigerator include: power on / off, temperature adjustment, operating time setting, and operating mode selection. In this embodiment, the temperature adjustment range of the car refrigerator can be -6°C to 55°C, that is, the car refrigerator supports cooling and heating functions, which can meet the storage temperature requirements of breast milk, medicines, cosmetics, food, etc. After the car is locked, the continuous operation time of the car refrigerator can be freely set between 1h and 24h. The operating modes of the car refrigerator may include soft freezing mode, cold drink mode, mother and baby mode, and insulation mode. The refrigerator control module can adjust the above working parameters, and collect the real-time working status information of the car refrigerator in real time, and send it to the client through the wireless communication module, or send it to the vehicle through the wired communication module. The client can view the working status of the car refrigerator in real time through the APP, such as the current temperature of the car refrigerator, the countdown time for locking the car, the temperature mode, and the switch status of the refrigerator door.

[0042] See also Figure 2The present invention also provides a control system for a vehicle refrigerator, which can be used to control the vehicle refrigerator as described in any of the above embodiments. The control system may include a vehicle communication module 100 and a central domain controller 200. Among them, the vehicle communication module 100 is the telematics & connectivity antenna module (TCAM) of the car, which is responsible for processing the communication between the car and the outside world. The vehicle communication module 100 and the central domain controller 200 are connected to each other through the CAN (Controller Area Network) bus and 1000M Ethernet (Gigabit Ethernet). The central domain controller 200 and the wired communication module of the vehicle refrigerator are connected to each other through the LIN bus.

[0043] In this embodiment, the vehicle communication module 100 can be used to receive the remote operation instruction sent by the client 400 through the cloud. The central domain controller 200 can be used to authenticate the remote operation instruction. After the authentication is passed, a corresponding second operation instruction is generated according to the remote operation instruction, and the second operation instruction is sent to the refrigerator control module 300. The refrigerator control module 300 can control the vehicle refrigerator to perform the corresponding operation according to the second operation instruction, and send the current working status information of the vehicle refrigerator to the central domain controller 200. Furthermore, the working status information can be sent to the client 400 through the vehicle communication module 100 for the user to query the information.

[0044] See also Figure 2 , Figure 3In one embodiment of the present invention, when a user uses the client 400 for the first time, he needs to log in to the APP (Application) on the client 400, register and create a personal account on the APP. The personal account can be used to bind car information, such as the car serial number and car purchase information. The client 400 can upload the relevant car information to the TSP (Telematics Service Provider) server 500 in the cloud, and the TSP server 500 will verify the car information and store it. When the user uses the client 400 again, he needs to enter the login credentials (such as user name and password). The client 400 encrypts the login credentials and sends them to the TSP server 500 to ensure the security of data transmission. After receiving the encrypted login credentials, the TSP server 500 will decrypt and verify its validity. If the login credentials are confirmed to be valid, the TSP server 500 will generate an access token and return it to the client 400. The access token serves as a temporary identity certificate, allowing the client 400 to perform further operations. When the client 400 wants to access certain functions or data, it must be accompanied by a valid access token obtained from the TSP server 500 to initiate an API request. When receiving an API request from the client 400, the TSP server 500 first checks whether the access token included in the request is valid. Only when the access token is valid will the TSP server 500 continue to process the request; otherwise, the request may be rejected or re-authentication may be required.

[0045] See also Figure 3 In one embodiment of the present invention, the vehicle refrigerator supports remote control. When the user is away from the vehicle, the functions of the vehicle refrigerator can be remotely controlled through the client 400, thereby providing the user with a diverse control experience. In this embodiment, after the APP login is successful, the client 400 can send a remote operation instruction for the vehicle refrigerator to the TSP server 500. The TSP server 500 can send the operation instruction to the central domain controller 200 through the vehicle communication module 100. After receiving the operation instruction sent by the vehicle communication module 100, the central domain controller 200 first authenticates the request with the vehicle communication module 100. If the authentication verification fails, the matching failure information will be returned to the client 400. If the authentication verification passes, the corresponding second operation instruction will be generated and sent to the refrigerator control module 300 through the LIN bus. The refrigerator control module 300 executes the corresponding control instruction according to the second operation instruction and returns the current working status information of the vehicle refrigerator. The vehicle communication module 100 receives the working status information of the vehicle refrigerator through the central domain controller 200 , and sends it to the client 400 through the TSP server 500 .

[0046] See also Figure 4In one embodiment of the present invention, the wireless communication module of the vehicle refrigerator may be, for example, a Bluetooth chip, which may be provided on the refrigerator control module 300, that is, the client 400 may be directly connected to the refrigerator control module 300 via Bluetooth, and the vehicle refrigerator may be controlled via the APP. In this embodiment, first, the client 400 turns on the Bluetooth function via the APP and searches for nearby Bluetooth devices. At the same time, the refrigerator control module 300 controls the wireless communication module to turn on the pairing mode and broadcasts a signal containing its name (usually set to a product model or a custom name) and a MAC address. The MAC address is a unique identifier for each network interface. When the client 400 receives the Bluetooth signal sent by the wireless communication module, the information of the device will be displayed in the list of optional Bluetooth devices provided by the APP. After the user selects the corresponding vehicle refrigerator from the list, the client 400 will send a pairing request to the refrigerator control module 300. During the pairing stage, both the client 400 and the refrigerator control module 300 will generate a random confirmation code. If the confirmation code matches successfully, the encryption key will be exchanged between the two devices. This step is to ensure that the subsequent data transmission is encrypted and protect the data from being intercepted or tampered with by a third party. When the key exchange is completed and the identities of each other are verified, an encrypted Bluetooth connection is established between the client 400 and the refrigerator control module 300. At this time, the user can directly send various operation instructions to the refrigerator control module 300 through the client 400, such as adjusting the temperature, turning on and off the machine, etc. The refrigerator control module 300 receives the first operation instruction through the wireless communication module, performs the corresponding operation, and feeds back the working status information of the vehicle refrigerator to the client 400 in real time through the wireless communication module, so that the user can monitor the real-time working status information of the vehicle refrigerator.

[0047] See also Figure 5In one embodiment of the present invention, the control system further includes a human-computer interaction module 600 and an audio amplifier module 700. The human-computer interaction module 600 can be connected to the central domain controller 200 through the FlexRay bus for communication, and the human-computer interaction module 600 can be used to receive user interaction instructions, such as voice commands. The audio amplifier module 700 is connected to the human-computer interaction module 600 through the CAN bus and A2B (Automotive Audio Bus). The audio amplifier module 700 can be used to control the playback and settings of the audio in the car. The vehicle refrigerator of the present invention supports voice control. After the user wakes up the vehicle by voice, the vehicle refrigerator can be controlled by voice. The user can issue various types of voice commands to control the vehicle refrigerator, such as turning on / off the power, adjusting the temperature, selecting the working mode, etc. In this embodiment, the user activates the vehicle system by saying a specific wake-up word and prepares to receive further voice information. After receiving the interaction instruction, the human-computer interaction module 600 converts it into a digital signal and sends it to the central domain controller 200 through the FlexRay bus. The central domain controller 200 receives the interaction instruction and recognizes and processes it. When it is recognized that the voice information is for the vehicle refrigerator, a corresponding second operation instruction is generated and sent to the refrigerator control module 300 via the LIN bus. After receiving the second operation instruction, the refrigerator control module 300 performs the corresponding operation according to the instruction, such as adjusting the internal temperature of the refrigerator or switching the working mode. After the refrigerator control module 300 completes the operation, it returns the working status information of the vehicle refrigerator to the central domain controller 200 via the LIN bus, and then the central domain controller 200 transmits it back to the human-computer interaction module 600 via the FlexRay bus. The human-computer interaction module 600 can update the received working status information and display it on the display screen, so that the user can see the current actual working status of the vehicle refrigerator. At the same time, the human-computer interaction module 600 can also broadcast the execution status of the voice instruction and the working status information of the vehicle refrigerator through the audio amplifier module 700. In this embodiment, voice commands include but are not limited to: opening / closing the refrigerator door, turning on / off the power, selecting different temperature modes (such as soft freezing, cold drinks, mother and baby, and keeping warm), adjusting the temperature (increasing / decreasing the temperature value, setting the highest / lowest / specified temperature), controlling the sterilization function, and setting the operating time after locking the vehicle.

[0048] In one embodiment of the present invention, the user can set the operating time of the vehicle refrigerator through the refrigerator control module 300. After the timer ends, the refrigerator control module 300 automatically controls to turn off the power supply to the refrigerator body. The user can also send a corresponding instruction through the client 400 to directly turn off the power supply to the refrigerator body.

[0049] For further information, see Figure 6In one embodiment of the present invention, the control system can also automatically control the power supply of the vehicle refrigerator according to the SOC state of the vehicle. Figure 1 As shown, the domain control module 800 and the central domain controller 200 can be communicatively connected via the FlexRay bus. The battery management module 900 can be communicatively connected to the domain control module 800 via the CAN bus. The central domain controller 200 can monitor the SOC status of the entire vehicle through the battery management module 900, and when the SOC reaches a preset threshold (for example, SOC equals 20%), it will send a second operation instruction for shutting down the power supply to the refrigerator control module 300 to shut down the power supply of the vehicle refrigerator and reduce the standby power consumption of the vehicle. Furthermore, the central domain controller 200 will also send a charging reminder to the client 400 through the vehicle communication module 100 to prompt the user to charge as soon as possible to avoid affecting travel.

[0050] The present invention also provides a car, which may include a car refrigerator in any of the above embodiments, and the car refrigerator may be, for example, arranged in the front armrest box of the car or the backrest of the rear seat. The car refrigerator is detachably connected to the car, and uses a universal power supply interface, which can be powered by a 12V car power supply or by an adapter outside the car, thereby meeting the user's continuous cooling needs. The car may also include a control system for the car refrigerator in any of the above embodiments, which can realize remote control, Bluetooth control, voice control and other control methods of the car refrigerator, thereby meeting the user's diverse control experience.

[0051] In summary, the present invention discloses a vehicle refrigerator and its control system, which improves the portability and versatility of the vehicle refrigerator, expands the control mode of the vehicle refrigerator, can adapt to the use requirements in different scenarios, and improves the comfort and convenience of outdoor travel. The control system of the vehicle refrigerator of the present invention has a variety of control modes. In addition to being adjusted through the physical buttons on the control panel, the vehicle refrigerator can also be remotely controlled by a mobile phone, controlled by Bluetooth, and voice controlled, satisfying the user's diverse control experience. Through the control system of the present invention, the user can check the working status information of the vehicle refrigerator at any time through the client. In addition, the present invention can also automatically control the power supply of the vehicle refrigerator according to the SOC of the whole vehicle, avoiding the power consumption of the vehicle refrigerator affecting the user's travel. Therefore, the present invention effectively overcomes the various shortcomings in the prior art and has a high industrial utilization value.
