One end of the second compression spring 59 is fixedly connected to the upper connecting column 57, and the other end of the second compression spring 59 is fixedly connected to the lower connecting column 58, thereby ensuring the stability of the refrigerator external unit 6.

[0028] As a preferred solution, when the refrigerator external unit 6 is subjected to force to compress the first compression spring 55 upward, the upper connecting column 57 does not separate from the lower connecting column 58 .

[0029] See also Figure 6-7 A slide groove 31 is provided on the top of the carriage 3, a slide rod 32 is provided below the slide groove 31, connecting plates 33 are provided downward at both ends of the slide rod 32, and a first connecting hole 34 is provided on the connecting plate 33. A partition plate 35 is provided at the bottom of the carriage 3, and the partition plate 35 is rotated 90° counterclockwise to connect with the connecting plate 33 to divide the carriage 3 into multiple cargo storage areas.

[0030] As a preferred embodiment, the partition plate 35 includes a first partition plate 351, a second partition plate 352 and a third partition plate 353. The first partition plate 351 is fixed in the carriage 3. A rotating shaft 354 is provided on the upper side of the second partition plate 352 and the third partition plate 353. The rotating shaft 354 is respectively connected to a movable grille 357 on the second partition plate 352 and the third partition plate 353. A connecting block 356 matching the connecting plate 33 is provided at the end of the grille plate 357. A second connecting hole 355 is provided on the connecting block 356. The movable grille 357 rotates in the carriage 3 through the rotating shaft 354 so that the first connecting hole 34 corresponds to the second connecting hole 355. At this time, the two movable grilles 357 are respectively perpendicular to the second partition plate 352 and the third partition plate 353, dividing the carriage 3 into three cargo areas.

[0031] As a preferred solution, the first partition plate 351 , the second partition plate 352 and the third partition plate 353 are all plate-like structures with holes, and gaps are left between adjacent first partition plates 351 and second partition plates 352 and between the second partition plates 352 and third partition plates 353 .

[0032] As a preferred solution, the first partition plate 351, the second partition plate 352 and the third partition plate 353 have the same length, and the second partition plate 352 and the third partition plate 353 divide the carriage into three equal parts when they are rotated 90° counterclockwise.

[0033] As a preferred embodiment, a water collecting tank 36 is further provided below the partition plate 35, and a plurality of reinforcing ribs 361 are evenly provided in the water collecting tank 36, the bottom of the reinforcing rib 361 is fixed in the water collecting tank 36, and the top of the reinforcing rib 361 is fixed on the bottom surface of the partition plate 35. The water collecting tank 36 is provided with a drain outlet 362 on the side close to the opening and closing door. When the temperature inside the vehicle rises, condensed water carried on the surface of the cargo will drip into the water collecting tank 36, and finally discharged from the refrigerated truck from the drain outlet 362.

[0034] Embodiment 2: Based on the above embodiment, one of the grille plates 357 can be rotated. At this time, one of the grille plates 357 is perpendicular to the bottom surface of the carriage 3, and the other grille plate 357 is parallel to the bottom surface of the carriage 3, so that the carriage 3 is divided into two cargo storage areas, one large and one small. The area of ​​the large cargo storage area is twice that of the small cargo storage area, and can be used to store goods of different sizes and types.

[0035] Since the refrigerator external unit 6 of the refrigerator hidden refrigerated vehicle of the present invention is hidden in the recess 4 on the top side of the compartment 3, when the front of the vehicle 1 needs to be repaired or maintained, no matter how it is turned over, the refrigerator external unit 6 will not be touched, thereby ensuring the stability of the refrigerator external unit 6. In addition, the installation box 5 is provided with a double shock absorbing device, a limit device and a clamping device 7, thereby ensuring the stability of the refrigerator external unit 6 in the installation box 5 and ensuring normal refrigeration in the compartment 3.

[0036] When there are many types of goods, the grid plate 357 is rotated 90 degrees so that the grid plate 357 is perpendicular to the second partition plate 352 and the third partition plate 353 respectively, and different goods are placed in different cargo storage areas. Since the space of the cargo storage area is smaller than that of the carriage 3, the moving range of the goods in the carriage 3 can be effectively reduced, and the goods can be prevented from being thrown due to bumps and turns of the refrigerated truck, thereby ensuring the stability of the goods in the carriage 3.

[0037] When the cargo is large or of a single type, the grid plate 357 is rotated 90° clockwise so that the grid plate 357 is placed flat on the second partition plate 352 and the third partition plate 353 for placing the cargo;

[0038] The water collecting tank 36 is used to collect water carried by the goods or condensed water inside the compartment, and finally discharge it from the refrigerated truck through the drain port 362 to ensure the internal environment of the compartment 3.

[0039] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0040] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
