Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0041] A cold storage tray according to an embodiment of the first aspect of this application, such as Figures 1 to 7As shown, the cold storage tray includes: a support component 1 for supporting items; a cold storage module 2 for absorbing the heat of the supported items; and a bottom beam 3, which is detachably installed on the lower surface of the support component 1, and the cold storage module 2 is installed inside the bottom beam 3; the thermal conductivity of the bottom beam 3 is less than that of the support component 1.

[0042] The support component 1 is used to support the items. It has a relatively high thermal conductivity, which facilitates the transfer of heat from the items to the cold storage module 2, thereby achieving effective cooling of the items. The bottom beam 3 is installed on the lower surface of the support component 1. It not only provides structural support for the entire cold storage tray and enhances the overall strength of the tray, but also forms a dedicated cold storage space because the cold storage module 2 is installed inside it.

[0043] Placing the cold storage module 2 within the bottom beam 3 facilitates its replacement, allowing for timely replacement when cold storage capacity is insufficient, thus ensuring continuous cooling. The bottom beam 3 is detachably connected to the load-bearing component 1. If the bottom beam 3 or its internal cold storage module 2 is damaged, the bottom beam 3 can be replaced independently, reducing maintenance costs. This also facilitates the replacement of different specifications of the bottom beam 3 and its internal cold storage module 2 according to varying cooling requirements. Furthermore, the internal space of the bottom beam 3 can accommodate more cold storage material or phase change material, increasing the cold storage capacity and providing a basis for extending the cooling time.

[0044] Because the bottom beam 3 has a low thermal conductivity, it can reduce the dissipation of cold energy from the cold storage module 2 to the external environment, thus avoiding the waste of cold energy. Meanwhile, the high thermal conductivity of the load-bearing component 1 ensures that the heat of the items can be efficiently absorbed by the cold storage module 2. The combined effect of the two allows the items to be maintained at a low temperature for a longer period of time, effectively improving the problems of poor cooling effect and short continuous cooling time of existing cold storage trays, and meeting the low-temperature environment requirements of perishable foods, fresh produce, medicines and other items during cold chain transportation.

[0045] In some cases, a heat insulation layer can be provided on the four sides of the supporting component 1, as well as in the empty area on the lower surface of the supporting component 1 (i.e., the area other than the connection between the bottom beam 3 and the supporting component 1) to further avoid the influence of heat in the environment on the cold storage module 2 and reduce the waste of cold energy in the cold storage module 2.

[0046] The cold storage module 2 may include an HDPE rectangular shell (which may contain graphene) and a phase change material, with the phase change material encapsulated within the shell. Multiple cold storage modules 2 can be configured and evenly arranged within the cavity of the bottom beam 3, such as... Figure 7 As shown.

[0047] According to one embodiment of this application, such as Figure 6As shown, the first end of the bottom beam 3 facing the support component 1 is configured as an opening 31; the cold storage tray also includes a cover plate 4 disposed at the opening 31, and the cover plate 4 and the bottom beam 3 enclose a cavity for accommodating the cold storage module 2.

[0048] The opening 31 provides a direct passage for the installation and replacement of the cold storage module 2, allowing it to be easily inserted or removed. The operation is simple and efficient, especially in cold chain operations, enabling rapid assembly of the cold storage module 2 and ensuring continuous cooling. The cavity formed by the cover plate 4 and the bottom beam 3 provides a stable space for the cold storage module 2, preventing displacement or shaking during transportation or loading, ensuring a stable relative position between it and the load-bearing component 1, and facilitating efficient heat transfer. The bottom beam 3 also provides excellent protection for the cold storage module 2, preventing damage from forklifts or other equipment during transportation and ensuring good cooling performance.

[0049] After the cover plate 4 closes the opening 31, it reduces the amount of cold energy dissipated from the cavity to the outside through the opening 31, enhancing the cavity's sealing performance. Combined with the low thermal conductivity of the bottom beam 3 itself, this further reduces the rate of cold energy loss. Simultaneously, the combined structure of the cover plate 4 and the bottom beam 3 strengthens the structural strength of the bottom beam 3 near the load-bearing component 1, preventing deformation at the opening 31 due to stress and ensuring the stability of the bottom beam 3's support for the load-bearing component 1. This structural design keeps the cold storage module 2 in a relatively enclosed environment, facilitating maintenance and replacement while maintaining good cold storage performance and improving the overall reliability of the cold storage tray.

[0050] According to one embodiment of this application, such as Figure 6 As shown, the edge of the opening 31 of the bottom beam 3 extends in a direction parallel to the cover plate 4 to form a flange 32, and the flange 32 is provided with a first connecting hole 321; the cover plate 4 is provided with a second connecting hole 41; the bearing component 1 is provided with a third connecting hole 13; the connector passes through the first connecting hole 321, the second connecting hole 41 and the third connecting hole 13 to fix the bottom beam 3 and the cover plate 4 to the lower surface of the bearing component 1.

[0051] The formation of the flange 32 increases the contact area between the bottom beam 3 and the cover plate 4 and the load-bearing component 1, making the force at the connection part more dispersed, reducing local stress concentration, improving the overall connection strength, and ensuring that the bottom beam 3 is not easy to loosen or deform when supporting the load-bearing component 1 and the weight of the items.

[0052] By using a single connector through three connecting holes, the bottom beam 3, cover plate 4, and load-bearing component 1 can be simultaneously fixed, ensuring the relative positional accuracy of the three components, preventing misalignment during assembly, and ensuring that the cover plate 4 can tightly fit the opening 31 of the bottom beam 3, enhancing the cavity's sealing performance and reducing the possibility of cold energy loss from the cold storage module 2 through gaps. At the same time, this integrated connection method simplifies the assembly process, eliminating the need for step-by-step fixing of individual components, improving assembly efficiency, and facilitating mass production.

[0053] The flange 32 extends in a direction parallel to the cover plate 4, making the contact surface between the cover plate 4 and the flange 32 flatter, further improving the sealing effect. The flange 32 itself can limit the cover plate 4, preventing the cover plate 4 from shifting when subjected to force, and ensuring the stability of the cold storage module 2 in the cavity.

[0054] In some cases, a groove can be provided on the mating surface of the flange 32 and the cover plate 4, and an elastic seal can be embedded in the groove. When the connector is tightened, the seal is compressed, which can fill the tiny gaps between the mating surfaces, further enhance the sealing performance, and reduce cold leakage.

[0055] According to one embodiment of this application, the connector is a riveted member.

[0056] The riveted parts are fixed by their own deformation, and the resulting connection structure has high stability and vibration resistance. During the transportation of the cold storage pallet, even if it is subjected to bumps or impacts, the bottom beam 3, cover plate 4 and bearing component 1 are not easy to loosen, ensuring that the three are always tightly fitted, thereby maintaining the airtightness of the cavity and reducing the leakage of cold energy from the cold storage module 2.

[0057] The riveting process is simple to operate, requiring no complex tools or techniques, and can adapt to the needs of large-scale production, improving the assembly efficiency of the cold storage tray. Simultaneously, the tight fit between the riveted parts and the connecting holes fills the tiny gaps between the mating surfaces, further enhancing the sealing effect and preventing heat from the external environment from entering the cavity through the gaps, thus affecting the cooling effect of the cold storage module 2. Furthermore, the riveted connection has good overall integrity, evenly transferring the load borne by the bottom beam 3 to the load-bearing component 1, improving the overall structural strength of the cold storage tray and ensuring that it is not easily deformed when bearing heavy items.

[0058] The connectors are riveted. When disassembly is required, a drill bit is used to drill a hole in the head of the riveted part to remove the fastening portion formed by deformation, thus releasing the clamping force of the riveted part on the flange 32, cover plate 4, and load-bearing component 1. At this time, the bottom beam 3, cover plate 4, and load-bearing component 1 can be separated from each other, facilitating the replacement of the cold storage module 2, or the repair and replacement of the bottom beam 3, cover plate 4, and load-bearing component 1. This detachable structure formed by riveting ensures high reliability of the cold storage tray during use and allows for convenient and quick assembly and disassembly. This enables the cold storage tray to be reused repeatedly by replacing the cold storage module 2 or damaged parts, greatly reducing the operating cost of the cold storage tray.

[0059] In some cases, the connectors may also be in the form of screws or bolts, with fastening structures to prevent loosening during operation.

[0060] According to one embodiment of this application, such as Figure 1 and Figure 5 As shown, the load-bearing component 1 includes a support frame 11, and multiple support rods 12 are installed within the space enclosed by the support frame 11.

[0061] The load-bearing component 1 can be a combination of a support frame 11 and multiple support rods 12. The space enclosed by the support frame 11 provides an installation base for the support rods 12. The multiple support rods 12 are distributed within this space. The gaps between adjacent support rods 12 and between the support rods 12 and the support frame 11 can reduce the amount of material used in the overall load-bearing component 1, thereby achieving an effective weight reduction effect. At the same time, the support frame 11, as an outer frame, can ensure the stability of the overall structure, while the support rods 12 can distribute and transfer the weight of the carried items to the support frame 11, ensuring that the load-bearing component 1 still has sufficient load-bearing capacity while reducing weight. It is suitable for cold chain transportation scenarios with strict requirements on the self-weight of the pallet and can reduce energy consumption during transportation.

[0062] The supporting component 1 can also take the form of a support plate. Its flat surface provides a continuous and stable support for items, preventing tilting or jamming due to gaps. This is suitable for irregularly shaped, easily rolling, and small items. The simple design of the plate facilitates cleaning and maintenance, reducing the accumulation of residual dirt. Furthermore, the overall continuity of the plate ensures even weight distribution, reducing the risk of structural damage due to excessive localized stress. When using a support plate, multiple parallel drainage channels can be created on its surface. These channels guide condensate to the edges and drain through the drain holes, preventing condensate buildup on the plate surface and its impact on item quality.

[0063] In some cases, the combination of support frame 11 and support rod 12 can be replaced with a grid plate structure. The grid plate consists of interlaced ribs forming a regular grid, which retains gaps to reduce weight while improving the load-bearing stability for small items through the regular grid. The support plate can be replaced with a corrugated plate. The wavy structure on the surface of the corrugated plate can enhance the plate's bending resistance and improve the overall structural strength while ensuring the load-bearing area. The grooves between the corrugations can also provide a certain degree of anti-slip effect.

[0064] According to one embodiment of this application, such as Figure 5 As shown, the support frame 11 includes four first square tubes connected end to end, forming a rectangular support frame 11; the support rod 12 includes a second square tube; both the first and second square tubes have reinforcing ribs 14 on their inner walls. The first and second square tubes are hollow structures.

[0065] The support frame 11 is formed by four first square tubes connected end to end, creating a rectangle. The hollow nature of the square tubes reduces material usage, achieving weight reduction. The symmetry of the rectangular frame ensures even stress distribution on all sides, stably supporting the weight of the items and preventing deformation due to excessive localized stress. The four first square tubes connected end to end form a closed structure, enhancing the overall rigidity of the support frame 11 and making it less prone to twisting under longitudinal or lateral forces, thus providing stable external support for the load-bearing component 1.

[0066] The support rod 12 adopts a second square tube, which serves as the internal support structure of the load-bearing component 1. It is distributed within the space enclosed by the support frame 11, which can further distribute and transfer the weight of the item to the support frame 11, thus preventing the support frame 11 from being damaged due to local load concentration.

[0067] Both the first and second square tubes can be equipped with reinforcing ribs 14 on their inner walls, which are connected to the inner walls of the square tubes to form an integral structure. The reinforcing ribs 14 and the square tubes can be an integral structure, which enhances the bending and compression resistance of the square tubes. Especially when bearing heavy objects, they can effectively resist the deformation of the square tubes caused by stress, ensure the structural stability of the square tubes, and extend their service life.

[0068] According to one embodiment of this application, such as Figure 2 and Figure 6 As shown, the cold storage tray also includes a temperature measuring unit 5. An opening 33 is provided on the end face of the bottom beam 3 along its length, and the temperature measuring unit 5 is installed at the opening 33.

[0069] The temperature measuring unit 5 forms close contact with the cold storage module 2 inside the bottom beam 3 through the opening 33, allowing direct detection of the temperature status of the cold storage module 2. This accurately reflects the low-temperature environment of the items on the load-bearing component 1, providing a direct basis for determining whether the cold storage module 2 still has effective cooling capacity. The temperature measuring unit 5 is installed on the end face along the length of the bottom beam 3, reducing interference from items during the temperature measurement process and facilitating integration with the data reading device on the forklift, enabling the data reading device to easily read the data from the temperature measuring unit 5.

[0070] The opening 33 provides a stable mounting base for the temperature measuring unit 5, allowing it to be firmly fixed to the bottom beam 3. This prevents the temperature measuring unit 5 from shifting or falling off due to vibration during transportation, ensuring reliable detection during long-term use. Simultaneously, this installation method does not damage the main structure of the bottom beam 3, which maintains its supporting strength for the load-bearing component 1. Furthermore, the opening 33 is located on the end face, minimizing its impact on the sealing of the internal cavity of the bottom beam 3 and not significantly increasing cold loss. Real-time temperature monitoring by the temperature measuring unit 5 allows for timely detection of insufficient cold energy in the cold storage module 2, facilitating timely replacement by operators. This ensures that items remain within the required low-temperature range, reducing the risk of spoilage due to temperature fluctuations and improving the safety and reliability of cold chain transportation.

[0071] According to one embodiment of this application, the temperature measuring unit 5 is an RFID chip.

[0072] The cold storage tray uses an RFID chip as the temperature measurement unit, which can significantly improve the intelligent management level of the cold chain conveying system. The RFID chip itself has wireless communication and data storage functions. While monitoring the temperature, it can wirelessly transmit real-time temperature data to an external reading and writing device. Information can be read without physical contact, realizing non-contact and automated monitoring of the temperature status of the cold storage tray, and greatly improving the intelligent level of cold chain management.

[0073] The RFID chip automatically records temperature change curves, forming a complete temperature data archive. This facilitates subsequent tracking of temperature fluctuations during transportation, providing data support for quality control. The RFID chip is installed at the opening 33 on the end face of the bottom beam 3. This allows for close-range sensing of the temperature of the cold storage module 2, ensuring detection accuracy, while avoiding direct contact with the carried items, reducing external interference. Furthermore, the chip itself is small in size and will not affect the structural strength of the bottom beam 3 or the stability of the cold storage module 2.

[0074] Leveraging the batch reading capabilities of RFID technology, multiple cold storage pallets can be monitored simultaneously, making it suitable for centralized management in large-scale cold chain logistics scenarios. By linking with an intelligent management system, it can automatically trigger an alarm when the temperature exceeds the preset range, promptly notifying management personnel to handle the situation and ensuring that the goods are always kept in a qualified low-temperature environment, thereby improving the overall efficiency and reliability of intelligent control of cold chain transportation.

[0075] In practical applications, a unique identifier code can be added to the RFID chip, so that each cold storage tray corresponds to an independent digital identity. Combined with temperature data, an "identity-temperature" associated file is formed, which makes it easy to accurately trace the historical status of a single tray.

[0076] According to one embodiment of this application, the bottom beam 3 is made of stainless steel, the load-bearing component 1 is made of aluminum alloy, and the cover plate 4 is made of aluminum alloy. The stainless steel can be 304 stainless steel. The surface of the aluminum alloy can be anodized.

[0077] Stainless steel possesses high structural strength and corrosion resistance. As the material for the base beam 3, it can stably support the weight of the load-bearing component 1 and the items, and adapt to the complex environments such as humidity and low temperatures that may be encountered during cold chain transportation. This protects the internal cold storage module 2 from external environmental corrosion, extending its service life. Simultaneously, stainless steel has a low thermal conductivity, effectively reducing the loss of cold energy from the cold storage module 2 to the outside through the base beam 3, maintaining the continuous cooling capacity of the cold storage module 2.

[0078] Aluminum alloy, with its excellent thermal conductivity and light weight, serves as the material for load-bearing component 1, enabling rapid heat transfer from the load-bearing items to the cold storage module 2 within the bottom beam 3, thus improving cooling efficiency. Its lightweight nature also reduces the overall weight of the cold storage tray, minimizing transportation energy consumption. Furthermore, the smooth surface and ease of processing of aluminum alloy provide a stable mounting base for intelligent components such as the temperature measuring unit 5, ensuring that the intelligent equipment is not easily loosened during transportation. This guarantees the continuity and accuracy of temperature data acquisition, providing a reliable data source for the intelligent monitoring system and facilitating real-time and precise control of the cold chain environment.

[0079] In some cases, the bottom beam 3 can also be made of aluminum-zinc coated steel plate, and the load-bearing component 1 can be made of aluminum-manganese alloy.

[0080] According to one embodiment of this application, three bottom beams 3 are provided along the width direction of the load-bearing component 1.

[0081] Three bottom beams 3 are arranged along the width of the load-bearing component 1, which can evenly distribute the weight of the load-bearing component 1 and the items it carries onto the three bottom beams 3. This prevents the load-bearing component 1 or the bottom beams 3 from deforming due to excessive stress at a single point, improves the overall structural stability and load-bearing capacity of the cold storage pallet, and ensures that the structure can maintain its integrity even if it encounters bumps or vibrations during transportation, thus providing a reliable structural foundation for the stable operation of the cold storage module 2.

[0082] The temperature measuring unit 5 is positioned on the end face of the middle bottom beam 3. This central position is symmetrically located at the width of the load-bearing component 1, resulting in a more balanced distribution of ambient temperature across the sides. This allows for a more accurate reflection of the overall temperature status of the cold storage tray. Compared to units positioned on the edge bottom beams 3, the measured data is more representative, effectively avoiding temperature measurement deviations caused by greater external environmental interference at the edges. Furthermore, the end face of the middle bottom beam 3 is more easily accessible to operators or intelligent devices during operation, facilitating data reading and maintenance of the temperature measuring unit 5. This reduces operational inconvenience caused by concealed locations, providing convenience for real-time temperature data acquisition and intelligent management. This ensures that management personnel can promptly and accurately grasp the cooling status of the cold storage module 2, improving the level of intelligent control in cold chain transportation.

[0083] Of course, in practical applications, temperature measuring units 5 can also be installed on the end faces of the three bottom beams 3.

[0084] The following are examples illustrating the dimensions of a cold storage tray:

[0085] The dimensions of the load-bearing component 1 can be 1200×1000×25mm, the cross-sectional dimensions of the first square tube and the second square tube can be 30×40 (in some cases, 25×50mm can also be used), the wall thickness is 1.5mm, the dimensions of the bottom beam 3 can be 1200×150×125mm, the dimensions of a single cold storage module 2 can be 195×145×120mm, the dimensions of the cover plate 4 can be 1200×150×1mm, and the overall dimensions of the cold storage tray can be 1200×1000×150mm.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should be covered within the scope of the claims of this application.
