[0002] In modern logistics and transportation, especially in the food and pharmaceutical sectors, multi-temperature zone transportation has become an indispensable requirement. Currently available multi-temperature zone transportation equipment, particularly for refrigerated truck bodies designed for new energy vehicles, typically uses a single refrigeration unit or a two-unit configuration to control the temperature of the entire truck body, then divides the truck body into different temperature zones using physical partitions or temperature-controlled curtains. In practice, this design often results in imprecise temperature control between zones, especially when goods are unevenly distributed or densely packed inside the truck body. This makes it difficult for cold air circulation to reach every corner, easily causing temperature fluctuations and cargo cooling. Utility Model Content

[0043] The embodiments of this utility model are described below with reference to the accompanying drawings.

[0044] One aspect of this application provides the superstructure of a new energy truck, including: a main body of the truck body; multiple refrigeration units, each refrigeration unit being installed within the main body of the truck body and having an independent control system; wherein at least one of the refrigeration units is connected to the power drive battery pack of the new energy truck and is directly powered by the power drive battery, which is the vehicle's own power drive battery, enabling the vehicle to move. This embodiment, by installing multiple refrigeration units within the main body of the truck body, each of which can be independently controlled, ensures precise adjustment of different temperature zones, meeting the transportation needs of goods such as food and pharmaceuticals that have strict requirements for transport environment temperature. The independent control system of the refrigeration units allows users to set different temperatures as needed, thereby achieving precise temperature control and insulation in multiple temperature zones. The refrigeration units are directly powered by the power drive battery, which not only improves energy utilization efficiency but also reduces dependence on external power sources, enhancing the system's autonomy and flexibility. In other embodiments, the accuracy and response speed of temperature control can be further improved by increasing the number of refrigeration units or improving the refrigeration efficiency of the refrigeration units, solving the problem of insufficient cooling capacity in high-temperature environments.

[0045] Furthermore, in one possible embodiment, each refrigeration unit is powered by a drive battery. This embodiment unifies the power supply for the refrigeration units, avoiding the complexity and instability that can arise from multiple power sources. Unified power supply via drive batteries simplifies the energy management system, ensures the continuity and stability of refrigeration unit operation, and also improves overall energy efficiency. This integrated design ensures stable temperature within the main body of the vehicle, maintaining good cooling performance even during long-distance transportation, providing strong protection for food safety and pharmaceutical quality. In other embodiments, optimizing battery energy management and distribution strategies can further improve refrigeration unit operating efficiency, reduce energy consumption, and extend battery life.

[0046] In one possible embodiment, at least one chiller is electrically connected to an auxiliary battery pack, which supplies power to the corresponding chiller. This embodiment provides a backup power supply for the chiller by introducing an auxiliary battery pack, enhancing system reliability and the ability to handle emergencies. When the power drive battery is low on charge or malfunctions, the auxiliary battery pack can seamlessly switch over and continue supplying power to the chiller, ensuring that temperature control remains unaffected. This design avoids the potential overload caused by relying on a single energy source, helps extend the lifespan of the main battery pack, and ensures temperature stability during cargo transportation. In other embodiments, a smart energy management system can monitor battery status in real time and automatically adjust the power supply mode to further improve energy efficiency and system stability.

[0047] Furthermore, the main body of the carriage also includes a junction box, which comprises: a housing, a wiring inlet, and multiple wiring outlets. The housing has a sealed cavity. The wiring inlet is located on the housing and exposed outside the housing. The wiring inlet is connected to a power source, which is a power-driven battery pack or an auxiliary battery pack. Multiple wiring outlets are located on the housing and exposed outside the housing. At least two chillers are electrically connected to each wiring outlet, and each chiller is electrically connected to a corresponding wiring outlet. The wiring inlet and each wiring outlet are electrically connected within the sealed cavity. The junction box design ensures safe and efficient transmission of wiring between the power source and each chiller, avoiding potential safety hazards caused by messy wiring. Centralized wiring management through the junction box enables convenient connection between the power source and the chillers. Simultaneously, the sealed cavity design prevents external factors such as rainwater from affecting the wiring, reducing the risk of short circuits. This structure improves the system's safety and maintainability, making independent control of the chillers more reliable. In other embodiments, wireless power transmission technology can be used to reduce wiring connections, further enhancing the system's safety and convenience.

[0048] Furthermore, the main body of the carriage also includes at least one partition, which divides the carriage into multiple refrigeration zones, with multiple refrigeration units distributed within each zone. The partitions allow for flexible division of the interior space, meeting the needs of multi-temperature zone transportation. The combination of partitions and refrigeration units forms an independent temperature control unit, improving the accuracy of temperature control and the safety of cargo storage. The technical solution in this embodiment enables the carriage to simultaneously transport goods requiring different temperature conditions, improving transportation efficiency and cargo compatibility. In other embodiments, adjustable partitions can be used to dynamically adjust the size of the temperature zones according to the actual needs of the goods, further improving space utilization efficiency.

[0049] Furthermore, at least one of the refrigeration units is installed on the front wall of the main body of the carriage, which is the side wall of the main body of the carriage near the front of the vehicle; at least one of the refrigeration units is installed on the first side wall, which is perpendicular to the front wall. Of course, the refrigeration units can also be installed on the rear side wall. The distribution of the refrigeration units on the side walls of the main body of the carriage expands the coverage area of ​​the cold air and improves the uniformity of temperature control. The technical solution in this embodiment helps maintain a balanced temperature throughout the entire main body of the carriage, especially in multi-point delivery scenarios, effectively preventing heat loss in the rear compartment and ensuring the quality of goods. In other embodiments, the refrigeration unit layout can be optimized, for example, by installing refrigeration units on the top of the main body of the carriage, utilizing the principle of rising hot air to improve the temperature distribution inside the main body of the carriage and enhance the cooling effect.

[0050] Furthermore, the main body of the carriage has a first area and a second area; each refrigeration unit is installed inside the main body of the carriage, with at least one refrigeration unit installed in the first area and at least one refrigeration unit installed in the second area; the main body of the carriage also includes: an exhaust duct, a return air duct, and a fan. The exhaust duct is installed on the inner wall of the main body of the carriage, and has a first air inlet and a first air outlet. The first air inlet is positioned relative to the first area of ​​the main body of the carriage, and the first air outlet is positioned relative to the second area of ​​the main body of the carriage; the fan is installed inside the exhaust duct to generate airflow within the exhaust duct; the return air duct has openings at both ends along its length, with the two openings located in the first area and the second area, respectively. The arrangement of the exhaust duct and the return air duct forms an effective air circulation system, improving refrigeration efficiency. The fan drives the airflow to circulate within the duct, accelerating heat exchange and making temperature control more rapid and precise. The technical solution in this embodiment ensures that even when goods are densely stacked, the temperature inside the main body of the carriage can remain balanced, effectively preventing localized excessively high or low temperatures and improving the safety of goods storage. In other embodiments, the uniformity and efficiency of cooling can be further improved by adding more fans or optimizing the air duct design to enhance airflow organization.

[0051] It should be noted that in some embodiments, the first region can be further divided into several more refined regions, and the second region can also be divided into several more refined regions.

[0052] Furthermore, both the exhaust and return air ducts are arranged along the length of the main body of the vehicle. This embodiment features a simple duct layout design, facilitating installation and maintenance. The ductwork, positioned along the length of the main body, ensures uniform distribution of cold air throughout the entire vehicle, avoiding cooling dead zones. This design improves duct utilization, resulting in more balanced temperature control within the vehicle, especially in multi-point delivery scenarios, effectively addressing temperature fluctuations caused by frequent door opening and closing, and maintaining stable cargo temperature. In other embodiments, a ring-shaped duct can be used to create omnidirectional airflow circulation, further enhancing cooling efficiency and temperature control uniformity.

[0053] Furthermore, the main body of the vehicle includes a roof panel, a front wall, a first side wall, and a second side wall. The roof panel is perpendicular to the front wall, the first side wall, and the second side wall, with the front wall facing the front of the new energy truck. The first and second side walls are positioned opposite each other. The main body of the vehicle also includes a first duct plate and a second duct plate. The first duct plate is fixedly connected to the roof panel and the first side wall, forming an exhaust duct, and a fan is mounted on the first duct plate. The second duct plate is fixedly connected to the roof panel and the second side wall, forming a return air duct. The integration of the duct plate with the main body of the vehicle makes the air duct structure more stable, facilitating installation and sealing. The integrated design of the fan and the duct plate optimizes the airflow path and improves airflow efficiency. The technical solution in this embodiment can effectively improve the airflow organization within the main body of the vehicle, making the cold air circulation smoother and the temperature control more precise. In other embodiments, the duct plate can be made of composite materials to improve its thermal insulation performance, further reducing cold air loss and improving cooling efficiency.

[0054] One aspect of this application provides a new energy freight truck, which includes the cargo box body as described in the above embodiments. This embodiment, by applying the aforementioned innovative technology to the new energy freight truck, constructs a highly integrated multi-temperature zone precision-controlled insulated transportation system. The power drive battery pack of the new energy freight truck powers the refrigeration unit, and combined with the air duct design and partition layout inside the cargo box body, precise temperature control and multi-temperature zone co-loading transportation are achieved. This solution significantly improves the transportation efficiency and cargo compatibility of the new energy freight truck, making it particularly suitable for the multi-temperature co-loading needs of scenarios such as chain coffee shops, tea shops, restaurants, and convenience stores, providing a solid guarantee for food safety and quality. In other embodiments, the overall range and temperature control stability of the vehicle can be further improved by upgrading the refrigeration unit performance and optimizing the energy management system, better meeting the market demand for high-efficiency, high-quality cold chain logistics services.

[0055] New energy freight vehicles can be pure electric vehicles (BEV), range-extended electric vehicles (EREV), plug-in hybrid electric vehicles (PHEV), hydrogen fuel cell vehicles (FCEV), etc.

[0056] Based on the above embodiments, the working process of the technical solution of this application is as follows: After the new energy truck starts, the power drive battery pack begins to supply power to the refrigeration unit inside the truck body. The user sets the target temperature for each temperature zone through the electronic control system, and the refrigeration unit operates independently according to the set parameters, achieving precise temperature control. Simultaneously, the fan generates airflow in the exhaust and return air ducts, accelerating the circulation of cold air inside the truck body and ensuring a balanced temperature distribution. During multi-point delivery, the side and rear doors of the truck body can be quickly opened and closed, improving loading and unloading efficiency, while the air duct system and insulation partitions effectively reduce temperature loss when opening the doors, maintaining a stable temperature inside the truck body. Furthermore, when the power drive battery pack's power is insufficient, an auxiliary battery pack automatically intervenes to provide power, ensuring the continuous operation of the refrigeration unit and ensuring the temperature safety of goods during transportation. The entire working process demonstrates the high efficiency, stability, and intelligent features of the technical solution of this application, providing a comprehensive and reliable solution for cold chain logistics of sensitive commodities such as food and pharmaceuticals.

[0057] The specific embodiments will be described in detail below with reference to the accompanying drawings:

[0058] Figure 1 The overall layout of a new energy freight truck is shown, with a cross-section of the main body of the truck bed to observe its internal structure. The main body 1, as the core of the entire design, is equipped with at least one refrigeration unit 2. These refrigeration units are distributed and each has its own independent control system, ensuring precise adjustment according to the different refrigeration requirements of the cargo. Notably, at least one refrigeration unit 2 is connected to the new energy freight truck's power drive battery pack 3, drawing power directly from the vehicle's main battery. Simultaneously, in some configurations, one or more additional refrigeration units may be connected to auxiliary battery packs 4. This flexible power supply mechanism ensures continuous refrigeration service under any circumstances.

[0059] The junction box 5, located inside the main body 1 of the carriage, plays a crucial role. The junction box 5 includes a housing 51, which is a sealed cavity. A wiring inlet 52 is located on the housing 51 and connects to the aforementioned power drive battery pack 3 or auxiliary battery pack 4 to receive power. Wiring outlets 53 are distributed throughout the housing, with each refrigeration unit 2 connected to it via an independent cable. This design ensures efficient power distribution and independent operation of the control system. Furthermore, the main body of the carriage is equipped with at least one partition 6, which divides the carriage space into multiple refrigeration zones 7, including a first zone 71 and a second zone 72. In this way, different types of goods can be properly preserved under different temperature conditions, greatly improving the efficiency and flexibility of cold chain logistics.

[0060] The exhaust duct 8, a key component of airflow circulation, has its first air inlet 81 facing the first area 71, and its first air outlet 82 pointing towards the second area 72. An internal fan 83 generates airflow within the exhaust duct 8, promoting air movement between the two areas. The return air duct 9 is also crucial, featuring a first air inlet 91 and a second air outlet 92, connecting the first area 71 and the second area 72. This ensures effective air circulation throughout the entire carriage, maintaining stable and uniform temperature conditions. To further clarify the carriage's structure, the position of the front of the carriage 21 is also indicated in the diagram.

[0061] Figure 2 A cross-sectional view of the main body of the carriage from a rear view angle is provided, revealing the layout details of its internal components. The structure of the main body 1 of the carriage consists of a roof plate 11, a front wall 12, a first side wall 13, and a second side wall 14. The front wall 12 is close to the front of the carriage 21, while the first side wall 13 and the second side wall 14 are located on both sides of the main body of the carriage, respectively. They are separated by a partition 6, forming independent refrigeration zones 7, including a first zone 71 and a second zone 72. It should be noted that the refrigeration zone 7 can also be divided into three or more zones by two or more partitions. The main application scenario in this application is two temperature zones, one refrigerated zone and one frozen zone. For example, the first zone 71 can be a refrigerated zone. In some embodiments, the first zone 71 can be further divided into two zones by a partition, while the second zone 72 can be a frozen zone. There are two refrigeration units 2, one installed on the front wall 12 to optimize space utilization, and the other installed on the first side wall 13. This layout ensures comprehensive temperature control coverage. Of course, there can be three or more chillers, for example, another chiller can be installed on the second side wall 14.

[0062] It is worth noting that the longitudinal extension of the exhaust duct 8 and return air duct 9 within the main body of the carriage ensures a uniform distribution of airflow. The first air inlet 81 of the exhaust duct 8 connects to the first area 71, while its first air outlet 82 faces the second area 72. The fan 83 plays a crucial role in this process, driving air circulation between the two areas. The return air duct 9 connects to the second area 72 via its first air inlet 91, and its second air outlet 92 returns air to the first area 71, completing the air circulation process and ensuring a uniform temperature within the main body of the carriage.

[0063] Figure 3 The image presents a top-down sectional view of the new energy truck. The front of the truck 21 occupies one end of the image, while the main body of the truck body 1 shows its complex internal structure. Below the roof 11, refrigeration units 2 can be seen scattered throughout the main body of the truck body. Some of these refrigeration units are mounted on the front wall 12 close to the front of the truck, while others are located on the first side wall 13 perpendicular to the front wall 12. This layout optimizes space utilization efficiency while also ensuring a uniform distribution of cooling effect.

[0064] The exhaust duct 8 and return air duct 9 are laid along the length of the main body 1 of the carriage. The first air inlet 81 of the exhaust duct 8 faces the first area 71, and then the fan 83 inside the duct pushes the air to the first air outlet 82 of the second area 72. At the same time, the return air duct 9 collects air from the second area 72 through the first air inlet 91 and finally returns it to the first area 71 through the second air outlet 92, completing the closed-loop airflow process. This design not only promotes airflow circulation inside the main body of the carriage, but also effectively avoids local temperature fluctuations and ensures the temperature stability of all refrigerated areas.

[0065] Of particular note is the structural design of the main body 1 of the carriage, in which the top plate 11, front wall 12, first side wall 13, and second side wall 14 together form a stable main frame. The first duct plate 10 is connected to the top plate 11 and the first side wall 13, forming an exhaust duct 8; while the second duct plate 12 is fixed to the top plate 11 and the second side wall 14, constructing a return air duct 9. These duct plates not only ensure smooth airflow but also increase the structural strength of the main body of the carriage, achieving a perfect combination of functionality and durability.

[0066] Figure 4 and Figure 5 The junction box 5 is described in detail as an electrical distribution hub. It receives external power input through line inlet 52 and then distributes the power to each chiller 2 through multiple line outlets 53, thereby achieving effective power management and distribution.

[0067] Figure 4 The three-dimensional structure of junction box 5 is shown. Figure 5 This provides its top-down view. The junction box 5 consists of a housing 51 with a wiring inlet 52 for receiving power from the drive battery pack 3 or the auxiliary battery pack 4. Multiple wiring outlets 53 are distributed inside the housing, connecting to the various refrigeration units 2 within the main body of the vehicle via specific cables. The housing is designed to be waterproof and dustproof to protect the internal circuitry from external environmental influences. Figure 4 and Figure 5 The intuitive demonstration shows that the junction box design fully considers ease of operation and functionality, ensures stable power transmission, reduces safety hazards caused by messy wires, and improves the overall system reliability and safety.

[0068] In summary, the aforementioned technical solution not only includes the efficient layout of the refrigeration unit, but also a precise electrical distribution network in the junction box, and an air circulation system composed of exhaust ducts, return air ducts, and duct plates, collectively creating a stable and controllable temperature environment inside the main body of the vehicle. Furthermore, the direct connection between the power drive battery and the refrigeration unit, along with the auxiliary power supply from additional batteries, achieves efficient energy utilization and flexible system response. The integrated application of this series of designs significantly improves the operating efficiency of new energy freight vehicles and the preservation quality of goods, bringing a revolutionary technological innovation to the cold chain logistics industry.
