DETAILED DESCRIPTION

[0019] Embodiments of the present application are described in detail below with reference to the attached drawing figures, wherein the same or like reference numerals and characters throughout the figures denote the same or like elements or components, which detailed description is only exemplary and not intended to limit the present application.

[0020] Referring to Figures 1 to 4 The present application provides a refrigeration device 100, which comprises a device body 101 and at least two functional modules 102. The device body comprises a frame 51, a partition plate 52 arranged in the frame 51, and a bus 60. The frame 51 and the partition plate 52 jointly form a storage space 70 and at least two module insertion positions 50. The storage space 70 is used to accommodate objects to be refrigerated. The bus 60 is arranged on the frame 51 and / or the partition plate 52. Each module insertion position 50 is provided with an electrically conductive part 53, which is electrically connected with the bus 60. The functional module 102 can be selectively inserted into the corresponding module insertion position 50 and electrically connected with the electrically conductive part 53 in the corresponding module insertion position 50, so as to be electrically connected with other functional modules 102 through the bus 60. The at least two functional modules 102 comprise a refrigeration module 10 and a power supply module 20. The refrigeration module 10 is used to provide cold energy for the storage space 70. The power supply module 20 is used to supply power for the refrigeration module 10.

[0021] The refrigeration device 100 maintains stable temperature and humidity to preserve or freeze objects and prolong shelf life. The refrigeration device 100 includes a refrigerator, a wine cabinet, a freezer, a refrigeration box for storing medicines, etc. Among them, the portable refrigeration device 100 can transport biological active samples such as vaccines, serums, and insulin at a constant temperature in an uncontrolled environment in disaster relief, refrigerate food or objects in outdoor activities or vehicle environments, or provide stable working or storage environments for temperature-sensitive sensors and fine chemical reagents in field scientific research or special operation environments.

[0022] The frame 51 can be an open frame 51 made of high-strength aluminum alloy or composite material. The frame 51 is provided with bus 60 tracks and mechanical fixing slots / guides to fix the functional modules 102 in the module insertion positions 50 and provide support for the electrical connection between the functional modules 102.

[0023] The partition plate 52 is a wall plate that cooperates with the frame 51 to form a refrigeration space, including a top plate, a bottom plate, a side plate, and a door plate. The partition plate 52 is generally made of thermal insulation material to prevent the ambient temperature from having a greater impact on the temperature inside the refrigeration device 100 and to prevent the loss of cold air inside the refrigeration device 100.

[0024] The bus 60 is a power supply and / or data transmission track or wire harness arranged on the frame 51 and / or the partition 52, used to realize power transmission and / or information interaction between the functional modules 102. The conductive part 53 in the module plug-in position 50 is electrically connected with the bus 60.

[0025] The module plug-in position 50 is a special mounting space enclosed by the frame 51 and the partition 52, used to carry the functional module 102 through electrical connection and mechanical fixation. The functional module 102 can be selectively plugged into the module plug-in position 50. The functional module 102 that has been plugged into the module plug-in position 50 can perform corresponding functions by using the power on the bus 60 through the conductive part 53.

[0026] The conductive part 53 is an electrical connection element arranged inside the module plug-in position 50 and connected to the bus 60, which is electrically connected with the corresponding interface on the functional module 102 to transmit power and / or data signals.

[0027] The module plug-in position 50 formed by the frame 51, the partition 52 and the bus 60 makes each functional module 102 physically separated but electrically connected, which can be independently installed and removed, making it easier and more convenient to maintain and update the modules, reducing the maintenance threshold and time cost. By replacing a specific module, the whole machine can immediately resume normal operation, reducing resource waste and improving resource utilization. A general failure of one functional module 102 does not affect the operation of other functional modules 102, reducing the risk of scrapping the whole machine.

[0028] Please refer to Figure 1 and Figure 3 In some embodiments, the module plug-in position 50 includes a plurality of power module plug-in positions 501, and the power module 20 includes a plurality of power modules 20. Each power module 20 is plugged into a corresponding power module plug-in position 501. The control module 40 is further configured to control the power supply mode of the plurality of power modules 20 based on the working mode of the refrigeration module 10.

[0029] Specifically, the power module 20 can be installed on the module plug-in position 50 through a drawer-type battery compartment or a flip-type battery compartment, and connected to the bus 60 through the conductive part 53 on the module plug-in position 50 to receive the control signal from the control module 40. The control signal can be determined by the control module 40 according to the temperature detected in the storage space 70 of the refrigeration equipment 100, the working mode preset by the refrigeration module 10, and the remaining power of the power module 20, etc. The power module 20 dynamically configures the series / parallel mode and outputs power according to the instruction of the control module 40.

[0030] This embodiment solves the problem that the portable refrigeration device 100 needs to be plugged in to work by setting up a power module 20. By setting up multiple power module plug-in positions 501, the available battery volume can be distributed to each power module 20 instead of using a large battery that may have high redundancy. Different numbers of batteries can be selected according to actual needs to provide power to the refrigeration device 100 during the required cooling time.

[0031] Please see Figure 3 In some embodiments, the power module 20 further includes an external power interface 21 for connecting an external power source to charge the power module 20.

[0032] The external power source can be a vehicle power supply, AC power, solar cells, or external energy storage power source. The external power interface 21 can be a vehicle DC input interface (such as a standard vehicle cigarette lighter interface), AC power input interface, photovoltaic DC input interface, or USB PD (Power Delivery) fast charging interface.

[0033] This embodiment proposes that, when a relatively stable power source is available, the refrigeration device 100 can be charged by connecting to an external power source and the power module 20. Compared to the portability of plug-in batteries, the external power interface 21 provides a more commonly used and stable power supply method.

[0034] Please see Figure 1 and Figure 2 In some embodiments, at least two functional modules 102 further include a detection module 30. The detection module 30 is used to detect temperature data within the storage space 70; and a control module 40 is electrically connected to the detection module 30, the cooling module 10, and the power module 20 via a bus 60. The control module 40 is used to control the start / stop frequency and operating power of the cooling module 10 based on the power information of the power module 20 and the temperature data.

[0035] The detection module 30 may include a temperature sensor, which is placed in the storage space 70 to monitor the internal temperature in real time and store the temperature data.

[0036] The control module 40 can be a control chip integrated inside the refrigeration equipment 100. It is connected to other functional modules 102 via bus 60 to realize functions such as powering on the control module 40 and communicating with the monitoring module and the refrigeration module 10.

[0037] The power information can be obtained from the battery management system built into the power module 20 via bus 60 communication.

[0038] This embodiment provides a detection module 30 and a control module 40, so that the control module 40 can obtain power information through the temperature data of the detection module 30 and the battery management system in the power module 20, thereby controlling the start and stop of the operation of the refrigeration module 10 and the working power of the refrigeration module 10 according to specific needs, making the refrigeration equipment 100 more intelligent and extending its service life.

[0039] Please see Figure 1 In some implementations, when the power of the power module 20 is higher than the first threshold and the temperature data is higher than the target temperature, the cooling module 10 is controlled to run continuously at the first operating power until the temperature data reaches the target temperature; when the power of the power module 20 is lower than the first threshold but higher than the second threshold, the cooling module 10 is controlled to run intermittently at the second operating power, which is lower than the first operating power.

[0040] The first and second thresholds are preset remaining power values, determined through actual testing or experience based on the specific model and configuration of the plug-in battery or external power supply. The temperature data is set according to the preservation requirements of the food or items within the refrigeration unit 100.

[0041] It is understandable that the operating power of the refrigeration module 10 is adjusted according to the actual situation. For an external independent energy storage power source or a plug-in battery, the remaining power determines the amount of power that the power module 20 can supply to the refrigeration module 10, while the temperature within the storage space 70 is the target that the refrigeration module 10 needs to achieve. Therefore, the operating power needs to be determined based on the power of the power module 20 and the temperature within the storage space 70. Under the first operating power, the power is sufficient and the refrigeration device 100 needs to be cooled significantly, which can be used for scenarios where a lot of items that need to be cooled have just been placed in the refrigeration device 100 and heat has accumulated. Under the second operating power, the power is sufficient for intermittent cooling, which can be used for most scenarios where the refrigeration device 100 is used for normal preservation.

[0042] In this embodiment, the control module 40 controls the refrigeration module 10 to operate at a power level appropriate to the state of the refrigeration equipment 100, based on the power information of the power module 20 and the temperature data detected by the detection module 30 in the storage space 70. At the first operating power, rapid cooling is achieved, ensuring the preservation effect of the refrigeration equipment 100. At the second operating power, the temperature inside the refrigeration equipment 100 is stabilized, energy is saved, and the power supply time is extended.

[0043] Please see Figure 1 and Figure 4 In some embodiments, the control module 40 is also configured to: control the cooling module 10 to stop working when the power of the power module 20 is lower than a second threshold, and send a low power alarm signal through the bus 60.

[0044] It is understandable that when the power of the power module 20 is lower than the second threshold, it means that the power is too low and cannot support the cooling module 10 to cool normally at the second working power. The control module 40 can control the cooling module 10 to stop working based on this power information, and drive the warning light to flash by sending a low power alarm signal, or drive the low power prompt to be displayed on the smart display screen, thereby reminding the user that the power is insufficient and cooling cannot continue.

[0045] This embodiment, powered by an external independent energy storage power source or a plug-in battery, promptly stops cooling and sends an alarm signal when the power level falls below a second threshold. This ensures timely disconnection of the power-consuming cooling module 10, guaranteeing the power supply's lifespan. Furthermore, the low power alarm prevents excessive cooling due to insufficient power from causing a direct power outage and halting the entire unit's operation.

[0046] Please see Figure 1 , Figure 2 and Figure 4 In some embodiments, the refrigeration module 10 includes: a first refrigeration module 10 based on a compressor; and a second refrigeration module 10 based on semiconductor refrigeration; when the first refrigeration module 10 is started, multiple power modules 20 are controlled to be connected in series to provide a first voltage; when the second refrigeration module 10 is started, multiple power modules 20 are controlled to be connected in parallel, or a portion of the multiple power modules 20 are controlled to be connected in parallel to provide a second voltage; wherein the first voltage is higher than the second voltage.

[0047] The first refrigeration module 10, based on compressor refrigeration, employs a method similar to that of a traditional household refrigerator. The compressor compresses the refrigerant under relatively high voltage, causing it to enter the condenser under high pressure and release heat to the external environment, condensing into a high-pressure liquid refrigerant. This high-pressure liquid refrigerant, after being depressurized by a throttling element, enters the evaporator. The refrigerant in the evaporator absorbs heat from objects within the storage space 70 and vaporizes, thus cooling the air or inner walls of the storage space 70. Subsequently, the gaseous refrigerant is drawn back into the compressor, forming a cycle. In this mode, because the compressor is a high-power, high-voltage driven component, its rated operating voltage is often higher than the output voltage of a single power module 20. For example, a single power module 20 outputs 12 volts (V), while the compressor requires 24V. By connecting multiple power modules 20 in series, the total voltage output to the compressor is equal to the sum of the voltages of each power module 20, thus meeting the high-pressure requirements for compressor startup and stable operation. Correspondingly, based on the compressor refrigeration method, the refrigeration power is relatively large, which is suitable for refrigeration equipment 100 with low requirements for refrigeration temperature and large storage space 70, and the refrigeration effect can reach 40°C lower than the ambient temperature.

[0048] Specifically, the control module 40 adjusts the compressor's start-stop frequency and operating power based on the temperature data obtained from the detection module 30 and the power information of the power module 20. For example, when the power is sufficient, the compressor is allowed to run at a higher power for a longer period of time to accelerate the temperature drop from the initial temperature to the target temperature; when the power is close to the threshold, the duty cycle is reduced to reduce the instantaneous load on the power module 20. At the same time, the control module 40 can avoid forcibly starting the compressor under low voltage conditions based on the number of series connections of multiple power modules 20 and real-time voltage changes, thereby reducing the risk of start-up failure and overcurrent damage, and improving the reliability and energy efficiency of the compressor refrigeration system in complex scenarios such as vehicle-mounted and battery-powered applications.

[0049] The second refrigeration module 10, based on semiconductor refrigeration, utilizes a semiconductor refrigeration chip for cooling, a common refrigeration and insulation method used in current vehicle refrigerators, insulated boxes for baby products, medicines, etc. This second refrigeration module 10 typically includes a semiconductor refrigeration chip and a fan or heat exchange component. The semiconductor refrigeration chip operates based on the Peltier effect; when a direct current passes through the junction of different conductive materials, heat is absorbed on one side of the chip to form a cold end, and heat is released on the other side to form a hot end. The cold end faces the storage space 70, transferring cooling to the food or items within it, while the hot end, in conjunction with a fan or other heat dissipation component, expells heat to the external environment. Compared to compressor refrigeration, semiconductor refrigeration requires a lower starting voltage. For example, the rated operating voltage of a semiconductor refrigeration chip is commonly 5V or 12V, and a single power module 20 can provide basic power. Furthermore, the cooling efficiency of the semiconductor refrigeration chip is positively correlated with the input current. Therefore, multiple power modules 20 need to be connected in parallel so that the total current input to the semiconductor refrigeration chip equals the sum of the currents of each power module 20, thereby improving cooling efficiency. Correspondingly, semiconductor cooling chips have no mechanical movement, relatively low noise, are suitable for small-volume applications, and can achieve a cooling effect 20°C-25°C below the ambient temperature.

[0050] Specifically, the control module 40 controls the activation of the second cooling module 10 based on temperature data, the power level of the power module 20, and a preset operating mode. It can prioritize lower power operation during low-power phases to maintain the temperature within the storage space 70 within acceptable fluctuation range. This significantly extends battery life and reduces instantaneous load on the battery while sacrificing some cooling speed, and avoids frequent high-current surges. For example, by outputting a high-frequency pulse-width modulation signal and adjusting the signal's duty cycle, the average input voltage and current of the thermoelectric cooler are changed, thereby controlling the operating power of the thermoelectric cooler.

[0051] In addition, whether it is compressor-based or semiconductor-based refrigeration, a good heat dissipation channel is required to dissipate hot air. The condenser needs to dissipate heat, and the heating end of the semiconductor refrigeration chip must dissipate heat in time. A corresponding heat dissipation channel interface or cooling fan should be set on the module plug-in position 50 of the refrigeration module 10 to ensure that the heat-generating part is aligned with the interface or fan during installation.

[0052] In this embodiment, the refrigeration module 10 serves as the core functional module of the refrigeration equipment 100. It is electrically connected to the conductive part 53 of the module plug-in position 50 through the first electrical connection part 1021, and obtains the power information of the power module 20 and the control command of the control module 40, thereby adjusting the start-stop frequency and working power. The refrigeration part (such as the refrigeration end of the semiconductor refrigeration chip, the evaporator) is oriented towards the part of the module plug-in position 50 that is connected to the storage space 70 to provide cooling. The heat generation part is aligned with the heat dissipation interface or fan to prevent heat accumulation and reduce the refrigeration effect of the refrigeration equipment 100.

[0053] Please see Figure 4 In some embodiments, the module insertion position 50 is provided with a guide structure 54 adapted to the functional module 102 and a locking mechanism 55. The guide structure 54 is used to limit and guide the functional module 102 during the insertion process, and the locking mechanism 55 is used to limit and lock the functional module 102 when it is inserted into place.

[0054] The guide structure 54 can be a slide rail on the frame 51. The slide rail can have guide grooves along the insertion direction to embed the bus 60, and mechanically fixed slots can be set on the corresponding module insertion positions 50 for different functional modules 102. The slide rail material can be aluminum alloy profile or galvanized steel sheet bending parts.

[0055] The locking mechanism 55 can be a metal or high-strength plastic buckle located at the tail or side of the module insertion position 50, with spring bias. It can take the form of a push-to-release button, internally cooperating with the locking element via a fork or linkage; pressing the button pushes or lifts the locking element, unlocking the functional module 102 from the locked position. Alternatively, it can be an exposed lever, allowing the bolt to be disengaged from the lock hole in the frame 51 simply by pressing or flicking it.

[0056] For example, during the assembly of the refrigeration equipment 100, the slide bar of the functional module 102 can be aligned with the guide groove of the slide rail, and it can be inserted in a straight line along the slide rail with a gentle push. The chamfer and the limit stop prevent misalignment or over-insertion. After the functional module 102 is in place, the buckle on the module mounting position automatically engages with the slot, locking and fixing the module so that there is no axial movement. If it is necessary to replace or repair the functional module 102, the functional module 102 can be smoothly pulled out by simply pressing or prying open the buckle, without the need for tool disassembly.

[0057] This embodiment, by providing a guide structure 54 and a locking mechanism 55 on the module insertion position 50, allows each functional module 102 to be easily disassembled and fixed to the main body of the equipment without tools, thereby improving disassembly and assembly efficiency and ensuring the flexible and reliable insertion and removal of the functional modules 102. The guide structure 54 and locking mechanism 55 on the frame 51 are compatible with each functional module 102, achieving a certain degree of standardization of the module insertion position 50.

[0058] Please see Figure 1 In some embodiments, the functional module 102 is provided with a first electrical connection part 1021, and the conductive part 53 in the module plug-in position 50 is a second electrical connection part 53 that cooperates with the first electrical connection part 1021; wherein, the first electrical connection part 1021 and the second electrical connection part 53 are in one of the following cooperation forms: the cooperation between a conductive terminal and an elastic electrical contact; the cooperation between a plug and a socket.

[0059] The first electrical connection portion 1021 is an electrical connection interface disposed on the functional module 102, which cooperates with the conductive element 53 or the second electrical connection portion 53 in the module plug-in position 50 to connect the bus 60 for transmitting electrical energy and / or transmitting communication signals. The first connection portion can be several planar or linear conductive terminals, such as gold-plated copper sheets or inserts, fixed to the end of the module plug-in position 50 connected to the second electrical connection portion 53. The first connection portion can also be a multi-core plug to allow for more flexible adjustment of the plug position via a wire harness.

[0060] The second electrical connection part 53 can be an elastic electrical contact with spring loading characteristics, used to provide axial elastic clamping force when the functional module 102 is inserted or removed, and to automatically compensate for gaps and maintain stable contact when the functional module 102 is inserted or removed. The second electrical connection part 53 can also be a socket, which can be directly connected to the bus 60 and, together with the first electrical connection part 1021, connects to the functional module 102.

[0061] This embodiment provides a structural component that electrically connects the module plug-in 50 to the functional module 102. Through the first electrical connection part 1021 and the second electrical connection part 53, it is ensured that the functional module 102 can be used as part of the refrigeration equipment 100 as a whole and perform corresponding functions through the connection of the bus 60.

[0062] Please see Figure 5 In some embodiments, functional module 102 further includes a network module 80, which is plugged into the corresponding module plug-in 50 for remote communication with the terminal device so that the terminal device can remotely monitor or control the refrigeration equipment 100; and / or, functional module 102 further includes a refrigeration sub-box module 90, which has an independent refrigeration space and is equipped with a refrigeration unit 91, which is used to provide cooling capacity to the refrigeration space.

[0063] The network module 80 may include a wireless communication chip and an antenna. The network module 80, installed in its corresponding mounting position, receives device status (temperature data, power information, etc.) from the control module 40 via the bus 60 through the conductive component 53. It then sends device status data to external terminal devices or receives remote control commands to interrupt the device. This allows for monitoring of temperature curves, power levels, and operating status via a mobile app / cloud platform, or remote setting of temperature / mode.

[0064] The refrigerated sub-module 90 can be understood as an additional sub-device sharing the power module 20 with the refrigeration equipment 100. It can be configured with a refrigeration unit 91 similar to the refrigeration module 10. By installing the refrigerated sub-module 90 into the corresponding module control position and connecting it to the bus 60, the control module 40 can also control the refrigeration start / stop frequency and operating power of the refrigeration sub-module 90. This expands the total module capacity and supports zoned temperature control (e.g., the refrigeration space 70 in the refrigeration equipment 100 is for refrigeration, while the refrigerated space in the refrigerated sub-module 90 is for freezing).

[0065] This embodiment introduces two extended function modules 102, namely network module 80 and refrigerated sub-box module 90, which can realize more powerful functions and implement more intelligent and diverse control according to actual needs.

[0066] All of the above technical solutions can be combined in any way to form the optional implementation methods of this application, and will not be described in detail here.
