To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0026] In some embodiments of this application, an expansion box is involved, such as Figure 1As shown, it includes a housing body 100, an isolation section 200, a mounting section, and a shock-absorbing section 400.

[0027] like Figure 1 , Figure 5 , Figure 7 As shown, the box body 100 includes a top 110, a floor 120, a side 130, a rear 140, and a door 150.

[0028] The top 110, floor 120, sides 130, rear 140, and door 150 enclose the container body 100, and the container body 100 forms a storage area. This storage area can be used to expand the storage area of ​​the container itself.

[0029] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the isolation section 200 is connected to the rear part 140 of the container body 100. The isolation section 200 is disposed between the container body 100 and the front end of the container. The isolation section 200 is used to separate the container body 100 from the front end of the container, so that there is a certain ventilation area between the container body 100 and the front end of the container. Since the refrigeration unit 610 is provided at the front end of the container, the above-mentioned ventilation area is used for the heat dissipation of the refrigeration unit 610. If the container body 100 and the front end of the container are placed close together, the heat of the refrigeration unit 610 will accumulate between the container body 100 and the front end of the container.

[0030] like Figure 7 As shown, multiple guide grooves 141 are spaced apart on the rear part 140, and the multiple guide grooves 141 are opened in parallel. The multiple guide grooves 141 can guide the flow of hot air in front of the chiller 610.

[0031] In some embodiments of this application, such as Figure 1 As shown, it also includes a lock 151, which is mounted on the door 150. The lock 151 is used for locking the position between the door 150 and the housing frame 160.

[0032] To facilitate the handling of the expansion box, such as Figure 1 , Figure 5 As shown, two bottom slots 161 are spaced apart at the bottom of the housing frame 160, and the bottom slots 161 are opened in the horizontal direction.

[0033] In some embodiments of this application, the housing body 100 further includes a housing frame 160. A top 110 is connected to the top side of the housing frame 160, a side 130 is connected to the side of the housing frame 160, a floor 120 is connected to the bottom side of the housing frame 160, a rear 140 is connected to the rear side of the housing frame 160, and a door 150 is connected to the side of the housing frame 160 opposite to the rear 140, and the door 150 can be opened and closed relative to the housing frame 160.

[0034] In other embodiments of this application, in order to facilitate the storage of the expansion container inside the container after it is detached from the front of the container, the top 110, floor 120, and side 130 are all connected to the rear 140 by hinges, and the top 110, floor 120, side 130, and door 150 can be folded relative to the rear 140. The folded expansion container can be easily stored inside the container.

[0035] To enhance the sealing performance of the expanded enclosure, a sealing part 500 is provided between the door 150 and the enclosure frame 160.

[0036] The sealing part 500 extends onto the side of the housing frame 160 connected to the door part 150.

[0037] A refrigeration unit 610 needs to be installed at the front of the refrigerated container. In remote areas or emergency scenarios, customers may choose to install a diesel generator 620. The diesel generator 620 typically occupies the upper space on the outer side of the front of the container, leaving the lower space on the outer side of the front of the container idle and wasting it. In this situation, the expansion container described in this application can be installed here. In this case, the isolation section 200 includes multiple first columnar structures and multiple second columnar structures. The multiple first columnar structures are spaced apart and connected axially to the rear section 140. The multiple second columnar structures are spaced apart and connected to the two front corner posts 630 of the container, with first corner holes on the first columnar structures and second corner holes on the second columnar structures. The mounting section includes multiple first connectors, which are detachably connected to the first and second columnar structures through the first and second corner holes.

[0038] In other embodiments of this application, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the isolation section 200 includes a third columnar structure 230 and a pre-embedded nut 240.

[0039] A through hole 231 is provided on the third columnar structure 230.

[0040] A connection hole 631 is provided on the front corner post 630 of the container, and a pre-embedded nut 240 is connected to the connection hole 631 inside the front corner post 630 of the container.

[0041] The mounting section includes bolts.

[0042] One end of the bolt extends into the connecting hole 631 and is threaded into the pre-embedded nut 240, while the other end of the bolt passes through the through hole 231 and is connected to the pre-embedded nut 240.

[0043] Both of the above methods can be used to install the expansion container below the generator at the front of the container.

[0044] In other embodiments of this application, the container is used for office, display, and other functions, and after being transported to its destination, no further handling is required. In this case, to expand the container's volume, an expansion container is connected to the outside of the container, thereby increasing the container's volume. In this state, such as Figure 8 , Figure 9 As shown, the mounting section includes a second connector 310. The isolation section 200 includes four fourth columnar structures 250, each with a third corner hole 251. The four fourth columnar structures 250 are respectively connected to the corners of the rear section 140. The second connector 310 is detachably connected to the container front frame corner fitting 640 via the third corner hole 251 and the container corner fitting corner hole.

[0045] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0046] Whenever possible, the various aspects and features described and shown in the specification can be applied individually, and these individual aspects can serve as the subject of a divisional application.

[0047] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
