It should be understood that the terms “length”, “width”, “upper”, “lower”, “front”, “back”, “top”, “bottom”, “inside”, “outside”, etc., indicating positions or positional relationships, are based on the positions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0048] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "several" means two or more, unless otherwise specifically defined.

[0049] For ease of understanding, this application uses the Figure 2 The direction indicated by the arrow A in the figure indicates the first direction, and the first direction is the front and rear direction of the refrigerated truck. Figure 2 The direction indicated by the arrow B indicates the second direction, which is the left and right direction of the refrigerated truck.

[0050] Please also refer to Figures 1 to 6 , the modular cold storage device and refrigerated truck provided by the present invention are now described. The modular cold storage device includes an insulating box body 1, a cold storage module 2 and a limiting structure 3; the insulating box body 1 is used to be installed on one side of the refrigerated compartment 5; an air outlet 111 and an air inlet 121 are provided on the rear side wall of the insulating box body 1, and a fan 13 is installed at the air outlet 111; the cold storage module 2 is arranged in the insulating box body 1; the cold storage module 2 includes a mounting frame 22 and a cold storage plate 21 connected to the mounting frame 22, and a movable component 4 is provided at the bottom of the mounting frame 22; the limiting structure 3 is fixed in the insulating box body 1 and is detachably connected to the mounting frame 22; wherein, the hot air flow in the refrigerated compartment 5 enters the insulating box body 1 from the air inlet 121, and the cold released by the cold storage plate 21 cools the hot air flow to form a cold air flow, and the fan 13 is used to guide the cold air flow into the refrigerated compartment 5.

[0051] The "front" and "rear" indicated in this application are distinguished by the distance between the insulating box body 1 and the refrigerated compartment 5. The side wall of the insulating box body 1 close to the refrigerated compartment 5 is defined as the rear side wall, and the side wall of the insulating box body 1 away from the refrigerated compartment 5 is defined as the front side wall.

[0052] The heat-insulating box body 1 is installed on one side of the refrigerated compartment 5, which is conducive to the centralized management and maintenance of the cold storage function and improves the refrigeration efficiency; the cold storage plate 21 stores cold energy for cooling. When the cold storage module 2 is moved for charging cold, only the mobile component 4 needs to be moved to drive the cold storage module 2 to move, which is convenient for charging cold and maintenance, improves convenience and reduces labor intensity.

[0053] It should be understood that the cold storage module 2 is arranged in the insulating box body 1, and the cold storage module 2 can be effectively limited by the limiting structure 3 to ensure a reliable cooling effect; that is, the limiting structure 3 and the mounting frame 22 in this application are detachably connected, which can facilitate the disassembly and assembly of the cold storage module 2 and improve the loading and unloading efficiency.

[0054] Optionally, the insulated box body 1 is a rectangular parallelepiped; illustratively, the side where the insulated box body 1 is connected to the refrigerated compartment 5 can be set as an open side to save installation materials. At the same time, a connecting rod is set on the open side so that the above-mentioned insulation structure can be installed on the connecting rod. Similarly, the bottom of the insulated box body 1 can also be set as an open side. In this case, it is necessary to directly fix the bottom of the insulated box body 1 to the bottom plate of the refrigerated compartment 5 to close the refrigerated compartment 5. It should be understood that the above-mentioned open side can be understood as not having the mounting plate 11. Specifically, whether the insulated box body 1 is provided with an open side can be set according to actual needs. However, it should be noted that when the insulated box body 1 is provided with an open side, the insulated box body 1 needs to enclose a closed installation space with the refrigerated compartment 5, and the closed installation space can exchange airflow with the refrigerated compartment 5 through the air inlet 121 and the air outlet 111 on the insulated box body 1.

[0055] Exemplarily, the air inlet 121 may be designed as a grille structure, the air outlet 111 may be configured as a circular hole structure, and the fan 13 may be installed at the air outlet 111 .

[0056] Optionally, the limiting structure 3 is a limiting bolt, which is passed between the mounting bracket 22 and the heat-insulating box body 1 to achieve the limitation of the mounting bracket 22.

[0057] Compared with the prior art, the modular cold storage device provided by the present invention modularizes the cold storage device into an insulating box 1 for accommodating the cold storage module 2, the cold storage module 2 for realizing cold release, and a limiting structure 3 for realizing the limiting of the cold storage module 2. The single small cold storage blocks in the prior art can be concentrated into an integrated cold storage plate 21, and the concentration of the cold storage plate 21 can be realized through the mounting frame 22, and the movement of the mounting frame 22 and the cold storage plate 21 can be realized through the moving component 4, thereby facilitating the transportation and loading and unloading of the cold storage module 2, improving the loading and unloading and installation efficiency, and being more convenient; and, in the present application, a fan 13 is set at the air outlet 111, which can accelerate the delivery of cold air to the refrigerated compartment 5, while improving the cooling effect.

[0058] Secondly, when protecting the goods in the refrigerated box from low temperatures, the present application adopts the setting of the insulated box 1, the air inlet 121 and the air outlet 111, so that the hot air flow in the refrigerated compartment 5 enters the insulated box 1 for heat exchange, and the fan 13 guides the cold air flow after heat exchange from the air outlet 111, which can avoid direct contact between the goods and the cold storage module 2. On the one hand, the cold air can slowly penetrate into the goods with the cold air flow, and the goods are in contact with the cold air flow transported to the refrigerated compartment 5, so that the goods in various places are cooled evenly, avoiding the problem of freezing caused by the direct contact of the goods close to the wall of the refrigerated compartment 5 with the cold storage plate on the compartment wall in the traditional way; on the other hand, the cold storage plate 21 can be effectively protected, and the odor of the goods with stronger odors on the cold storage plate 21 can be reduced, which affects the recycling use of the cold storage module 2.

[0059] See also Figure 1 In some possible embodiments, the rear side wall of the insulation box body 1 includes a mounting plate 11 and a movable plate 12; the mounting plate 11 is fixed to the top plate of the insulation box body 1, and a plurality of air outlets 111 are provided on the mounting plate 11, and each air outlet 111 is provided with a group of fans 13; the movable plate 12 is provided at the bottom of the mounting plate 11, and the two sides of the movable plate 12 are hinged to the two side walls close to the insulation box body 1; the bottom of the movable plate 12 is provided with an air inlet 121.

[0060] The mounting plate 11 is fixed to the top plate of the heat-insulating box body 1 and is used to fix the positions of the air outlet 111 and the fan 13; the movable plate 12 is used to facilitate the rotation and opening of the heat-insulating box body 1 so as to move the cold storage module 2 into the heat-insulating box body 1; at the same time, an air inlet 121 is provided at the bottom of the movable plate 12, which is conducive to the natural rise of the hot air flow and the heat exchange with the cold storage module 2, thereby improving the cooling efficiency.

[0061] Optionally, anti-collision angles are set on the left and right side panels of the insulation box body 1 to prevent the movable panel 12 from colliding with the cold storage module 2 when it is closed; optionally, the two groups of cold storage modules 2 and the two hinged doors of the movable panel 12 correspond to each other front and back.

[0062] Preferably, the plurality of air outlets 111 are arranged at intervals along the second direction, and the air inlet 121 at the bottom is also extended along the second direction.

[0063] Specifically, the movable panel 12 is a double-door structure, and the two movable doors of the double-door structure can be opened to both sides around the hinge ends thereof to facilitate loading and unloading of the cold storage module 2 .

[0064] See also Figure 1 In some possible embodiments, the axial direction of the air outlet 111 is defined as a first direction, and the horizontal direction perpendicular to the first direction is defined as a second direction; two groups of cold storage modules 2 are arranged at intervals along the second direction in the heat-insulating box body 1, and the two groups of cold storage modules 2 are respectively connected to the limiting structure 3.

[0065] By arranging two groups of cold storage modules 2 at intervals in the insulating box body 1, the cold storage modules 2 can be easily removed, and the problem of the integrated cold storage modules 2 being too large in mass and volume affecting loading, unloading and transportation can be avoided; at the same time, each group of cold storage modules 2 is connected to the limiting structure 3 respectively, which can ensure the connection stability of each cold storage module 2.

[0066] In addition, setting up two groups of cold storage modules 2 can facilitate the setting of a limiting structure 3 between the two cold storage modules 2, thereby improving the convenience of installation; at the same time, it can increase the cold storage area, store more cold capacity, extend the cold preservation time, and reduce energy consumption.

[0067] See also Figure 3In some embodiments, the limiting structure 3 includes a horizontal limiting member 31 and a pipe clamp 32; the horizontal limiting member 31 is arranged between the two groups of cold storage modules 2; one end of the horizontal limiting member 31 is fixed on the front side wall of the heat insulation box 1 opposite to the side where the air inlet 121 is located, and the other end extends toward the middle of the two groups of cold storage modules 2; a first limiting pin 313 is passed through between the horizontal limiting member 31 and the mounting bracket 22; the pipe clamp 32 and the horizontal limiting member 31 are arranged at an upper and lower intervals; one end of the pipe clamp 32 is fixed on the front side wall of the heat insulation box 1, and the other end is provided with two groups of slots 321 with openings corresponding to the two cold storage modules 2, and the slots 321 are clamped with the mounting bracket 22 of the corresponding cold storage module 2.

[0068] By setting a horizontal limiter 31 and passing a first limit pin 313 between the horizontal limiter 31 and the mounting frame 22, the horizontal displacement of the cold storage module 2 is avoided, thereby improving the stability of the limit of the cold storage module 2; at the same time, it prevents left and right shaking and ensures the consistency of the cooling effect.

[0069] In addition, the horizontal limiter 31 is provided between the two groups of cold storage modules 2, so that the two groups of cold storage modules 2 can be connected at the same time, which reduces the mass of the limiter structure 3, reduces the complexity of the structure, and saves processing costs.

[0070] By setting the pipe clamp 32, the cold storage module 2 is further limited; the horizontal limiter 31 and the pipe clamp 32 are set at intervals up and down, which can limit and fix the cold storage module 2 from the top and bottom directions, enhance stability, reduce position deviation, and maintain stable operation of the device.

[0071] Specifically, the pipe clamp 32 comprises a π-shaped mounting plate 11 and two sets of opposing clamps. The clamps are fixed to the flat side of the π-shaped mounting plate 11. The two clamps have arcuate notches that mate with the outer circumferential walls of the mounting posts of the mounting bracket 22. The arcuate notches on the two clamps form the aforementioned clamping slots 321. The two clamps are clamped onto the mounting posts of the mounting bracket 22 to restrain the mounting bracket 22. The other side of the π-shaped mounting plate 11 is clamped onto both sides of the connecting pipe within the insulation box 1 and secured with bolts.

[0072] It should be understood that when the two card plates are spaced relative to each other along the second direction, the left and right movement of the mounting frame 22 can be restricted; when the two card plates are spaced relative to each other along the first direction, the front and back movement of the mounting frame 22 can be restricted; when the two card plates are spaced apart along the up and down directions, the up and down movement of the mounting frame 22 can be restricted. The specific setting method can be selected according to actual needs.

[0073] See also Figure 3, exemplarily, the horizontal limit member 31 includes a guide tube 311 and two pairs of first limit plates 312; the guide tube 311 has a V-shaped structure; the V-shaped tip of the guide tube 311 faces the cold storage module 2, and the other end is fixed to the front side wall of the insulation box 1; the two pairs of first limit plates 312 correspond one to one with the two groups of cold storage modules 2; each pair of first limit plates 312 are arranged at intervals up and down, and are correspondingly fixed on the upper and lower sides of the guide tube 311; each pair of first limit plates 312 extends toward the cold storage module 2 and is clamped on the corresponding mounting column of the mounting frame 22, and a first limit pin 313 is passed through each pair of first limit plates 312 and the corresponding mounting column.

[0074] By setting the guide tube 311 into a V-shaped structure, with its tip facing the cold storage module 2, and fixing it to the front side wall of the box body, it is convenient to guide the cold storage module 2 for accurate installation.

[0075] It should be noted that there are two first limit plates 312 in each pair, and the two first limit plates 312 are clamped on the mounting column of the mounting frame 22 up and down so that the first limit plates 312 and the mounting column are connected by the first limit pin 313; specifically, the first limit pin 313 passes through the upper first limit plate 312, the mounting column and the lower first limit plate 312 in the vertical direction in sequence to achieve horizontal limitation of the mounting frame 22, thereby enhancing stability and preventing horizontal displacement.

[0076] Optionally, the guide tube 311 may also be a plate-shaped structure, used to limit the mounting bracket 22 together with the first limiting plate 312 and the first limiting pin 313 .

[0077] Exemplarily, there are multiple horizontal limit members 31, and the multiple horizontal limit members 31 are arranged at intervals between the two groups of cold storage modules 2; there are multiple pipe clamps 32, and the multiple pipe clamps 32 are arranged at intervals between the two groups of cold storage modules 2; preferably, the number of the horizontal limit members 31 and the pipe clamps 32 are both two, and are symmetrically distributed at the upper and lower ends of the insulation box 1.

[0078] See also Figure 4 In some embodiments, the limiting structure 3 also includes a second limiting plate 33; one end of the second limiting plate 33 is fixed on the rear side wall of the insulation box body 1, and the other end abuts against the upper side of the mounting column of the mounting frame 22; wherein, the second limiting plates 33 are provided in multiple groups, and the multiple groups of second limiting plates 33 are spaced apart on the rear side wall of the insulation box body 1.

[0079] Multiple groups of second limiting plates 33 are arranged at intervals, and the second limiting plates 33 abut against the upper side of the mounting column of the mounting frame 22 to prevent the cold storage module 2 from moving up and down. Together with other limiting structures 3, they ensure the stability of the module position and improve the reliability of the device and the continuity of cooling.

[0080] Preferably, each cold storage module 2 corresponds to multiple second limit plates 33; it should be understood that the mounting frame 22 is an upward-opening bracket structure assembled from multiple groups of mounting columns, and multiple second limit plates 33 can be abutted on the upper side of each horizontally extending mounting column.

[0081] See also Figure 5 , exemplarily, the limiting structure 3 also includes two groups of positioning rails 34; the two groups of positioning rails 34 correspond one-to-one to the two groups of cold storage modules 2, and are fixed at both ends of the insulation box 1 along the second direction; wherein, the number of each group of positioning rails 34 is two, and the two positioning rails 34 are arranged at intervals in the front and rear along the first direction, and are limited at the front and rear sides of the corresponding mounting frame 22.

[0082] The two sets of positioning rails 34 correspond to the two sets of cold storage modules 2, and the two positioning rails 34 limit the front and rear sides of the mounting frame 22, providing an installation positioning reference for the cold storage module 2, improving the installation accuracy and stability, and ensuring the compact structure of the device and efficient cooling.

[0083] By fixing the positioning rails 34 at both ends of the box body, the mounting bracket 22 can be conveniently pushed into the insulating box body 1 from the middle thereof, thereby avoiding interference of the positioning rails 34 with the movement of the mounting bracket 22 .

[0084] It should be understood that one end of the positioning rail 34 is fixed on the left side wall or the right side wall of the insulating box body 1, and the other end extends toward the middle of the insulating box body 1, and the extension length should not be too long to avoid affecting the movement of the mounting bracket; further, the extended end of the positioning rail 34 bends and extends into the refrigerated compartment 5 to guide the mounting bracket 22 into between the two positioning rails 34.

[0085] See also Figure 6 In some possible embodiments, the moving assembly 4 includes a swing arm 41 and a moving wheel group 42; the swing arm 41 is horizontally arranged at the bottom of the mounting frame 22, and the center of the swing arm 41 is rotatably connected to the center of the bottom of the mounting frame 22; the swing arm 41 has an extended state in which it swings to be perpendicular to the cold storage plate 21, and both ends extend beyond the front and rear plate surfaces of the cold storage plate 21. The swing arm 41 also has a retracted state parallel to the plate surface of the cold storage plate 21; the moving wheel group 42 includes a main wheel group 421 provided at the bottom of the mounting frame 22, and an auxiliary wheel group 422 provided at the bottom of the swing arm 41; and the bottom of the auxiliary wheel group 422 is flush with the bottom of the main wheel group 421.
