Moreover, for example, the term "first component" does not imply the existence of "second component," and the term "second component" does not imply the existence of "first component."

[0058] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0059] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0060] Unless otherwise stated, the numerical ranges in this document include not only the entire range within its two endpoints, but also the subranges contained therein.

[0061] Figures 1 to 8 The diagram shows a container frame 100 according to the present invention, the frame 100 being configured to be 20 feet or 40 feet in length.

[0062] When the base frame 100 is constructed to be 20 feet long (e.g.) Figure 1 , Figure 5 as well as Figure 7 (In one embodiment of the base frame 100), the base frame 100 includes at most two first floor panels 141, which are configured to form at most one seam 142 extending along the width direction D2 or the length direction D1 of the base frame 100.

[0063] When the base frame 100 is constructed to be 40 feet long (e.g.) Figure 3 , Figure 6 as well as Figure 8 (In one embodiment of the base frame 100), the base frame 100 includes at most two first floor panels 141 and two second floor panels 243. The at most two first floor panels 141 are configured to form at most one seam 142 extending along the width direction D2 or the length direction D1 of the base frame 100. The two second floor panels 243 are disposed at one end of the base frame 100 and arranged along the length direction D1 or the width direction D2 of the base frame 100.

[0064] According to the container frame 100 of this utility model, the first floor 141 forms at most one splice seam 142, which can reduce the arrangement of the floor beam 370 or the second bottom crossbeam 580 in the frame 100, thereby reducing the weight and cost of the container.

[0065] In general, the base frame 100 includes a bottom side beam 110, a front sill 120, and a first bottom crossbeam 130. The bottom side beam 110 extends along the length direction D1 of the base frame 100. The front sill 120 extends along the width direction D2 of the base frame 100 and is located at the end of the bottom side beam 110 along the length direction D1. The first bottom crossbeam 130 extends along the width direction D2 and is connected to the bottom side beam 110.

[0066] Optionally, the number of first floor 141 can be one (e.g., Figure 1 as well as Figure 3In the embodiment of the underframe 100, in other words, the first floor 141 is constructed as a single piece of floor within the underframe 100. The length of the first floor 141 is 5800mm to 8600mm, and the width of the first floor 141 is 2300mm to 2340mm. This avoids the formation of splice seams 142, thereby reducing the arrangement of floor beams 370 or second bottom crossbeams 580 in the underframe 100, and thus reducing the weight and cost of the container.

[0067] Optionally, the number of first floor 141 can also be two (e.g. Figures 5 to 8 In one embodiment of the base frame 100, the length of the first floor 141 is 2900mm to 8600mm, the width of the first floor 141 is 1100mm to 2340mm, and a splicing seam 142 is formed between two first floor 141s. Figure 9 As shown, the base frame 100 includes a floor center beam 370 extending along the length direction D1 or a second bottom crossbeam 580 extending along the width direction D2, the width of the second bottom crossbeam 580 being greater than the width of the first bottom crossbeam 130. The projection of the splice seam 142 along the height direction D3 of the base frame 100 completely falls within the projection range of the floor center beam 370 or the second bottom crossbeam 580 along the height direction D3, and at least two layers of adhesive are provided in the splice seam 142, the adhesive being connected to the first floor 141 and connected to the floor center beam 370 or the second bottom crossbeam 580.

[0068] Optionally, refer to Figure 9 The first bottom crossbeam 130 includes a first upper wing plate 131, a first connecting plate 132, and a first lower wing plate 133. The first upper wing plate 131 and the first lower wing plate 133 are spaced apart along the height direction D3 of the underframe 100. The top end of the first connecting plate 132 is connected to the first upper wing plate 131, and the bottom end of the first connecting plate 132 is connected to the first lower wing plate 133. The first connecting plate 132 is arranged on the same side of the first upper wing plate 131 and the first lower wing plate 133 along the length direction D1 of the underframe 100. The first bottom crossbeam 130 has a stable structure and low manufacturing cost.

[0069] Optionally, refer to Figure 9 The second bottom crossbeam 580 includes a third upper flange 581, a third connecting plate 582, and a third lower flange 583. The third upper flange 581 and the third lower flange 583 are spaced apart along the height direction D3 of the base frame 100. The top end of the third connecting plate 582 is connected to the third upper flange 581, and the bottom end of the third connecting plate 582 is connected to the third lower flange 583. The third connecting plate 582 is arranged on the same side of the third upper flange 581 and the third lower flange 583 along the length direction D1 of the base frame 100. The second bottom crossbeam 580 has a stable structure and low manufacturing cost.

[0070] Optionally, refer to Figure 9 The width h1 of the first bottom crossbeam 130 (i.e., the dimension of the first upper wing plate 131 and the first lower wing plate 133 along the length D1 of the base frame 100) is 45mm, and the height h2 of the first bottom crossbeam 130 (i.e., the distance between the top surface of the first upper wing plate 131 and the bottom surface of the first lower wing plate 133) is 122mm. The width h3 of the second bottom crossbeam 580 (i.e., the dimension of the third upper wing plate 581 and the third lower wing plate 583 along the length D1 of the base frame 100) is 75mm, and the height h4 of the second bottom crossbeam 580 (i.e., the distance between the top surface of the third upper wing plate 581 and the bottom surface of the third lower wing plate 583) is 122mm. The width h3 of the second bottom crossbeam 580 is greater than the width h1 of the first bottom crossbeam 130. Therefore, the weight of the second bottom crossbeam 580 is greater than the weight of the first bottom crossbeam 130. Reducing the use of the second bottom crossbeam 580 can reduce the weight of the underframe 100 and even the container.

[0071] The following description, in conjunction with the accompanying drawings and various specific embodiments, will illustrate the container base 100 of this utility model.

The mating notch 267 is provided with a mating inclined surface 268 that fits into the outer wall of the gooseneck groove plate 261, thereby strengthening the connection between the short bottom crossbeam 262 and the gooseneck groove plate 261 and making the gooseneck groove plate 261 more stable.

[0090] The above-described configuration enables the chassis 100 according to the second embodiment to be adapted to a gooseneck chassis vehicle.

This allows the top surface of the short bottom crossbeam 262 to be flush with the top surface of the first bottom crossbeam 130, which is suitable for maintaining the flatness of the second floor 243 and the first floor 141, and also suitable for the short bottom crossbeam 262 to be installed on the gooseneck groove plate 261. In addition, the height h6 of the short bottom crossbeam 262 is smaller than the height h2 of the first bottom crossbeam 130, which helps to reduce the weight of the container.

[0098] Third Implementation Method

[0099] Reference Figure 5 The main difference between the base frame 100 of the first embodiment and the base frame 100 of the third embodiment is that the base frame 100 includes a floor beam 370 and two first floor 141.

[0100] In detail, two first floorboards 141 are arranged along the width direction D2 and form a splice seam 142 extending along the length direction D1. The two ends of the floor beam 370 are respectively connected to the two front sills 120 (one of which is a threshold 121). The edges of the splice seam 142 formed by the first floorboards 141 overlap with the floor beam 370, so that the floor beam 370 can support the edges of the splice seam 142 formed by the two first floorboards 141, making the installation of the two first floorboards 141 more stable.

[0101] Optionally, the colloid can also be applied between the top surface of the floor beam 370 and the bottom surface of the first floor 141, creating a sealed connection between them and reducing the accumulation of microorganisms on the base frame 100. Because the joint 142 has two layers of colloid, the depth within the joint 142 is reduced, further minimizing the accumulation of microorganisms.

[0102] Optionally, the length of the first floor 141 is 5800mm to 5820mm, and the width of the first floor 141 is 1150mm to 1170mm. Although this requires the installation of a floor center beam 370 in the base frame 100 according to the third embodiment, it eliminates the need for the installation of a second bottom crossbeam 580 compared to existing containers, thus reducing the weight and cost of the container.

[0103] Preferably, the length of the first floor 141 is 5810mm and the width of the first floor 141 is 1160mm.

[0104] Fourth Implementation Method

[0105] Reference Figure 5 The main difference between the base frame 100 of the second embodiment and the base frame 100 of the fourth embodiment is that the base frame 100 includes a floor beam 370 and two first floor 141.

[0106] In detail, two first floorboards 141 are arranged along the width direction D2 and form a joint 142 extending along the length direction D1. The first end of the floor beam 370 is connected to the front sill 120 (i.e., the threshold 121), and the second end of the floor beam 370 is connected to the gooseneck main beam 260. The edges of the first floorboards 141 forming the joint 142 overlap with the floor beam 370, thereby allowing the floor beam 370 to support the edges of the joint 142 formed by the two first floorboards 141, making the installation of the two first floorboards 141 more stable.

[0107] Optionally, the length of the first floor 141 is 8580mm to 8600mm and the width of the first floor 141 is 1150mm to 1170mm. Although this requires the installation of a floor center beam 370 in the base frame 100 according to the fourth embodiment, it eliminates the need for the installation of a second bottom crossbeam 580 compared to existing containers, thus reducing the weight and cost of the container.

[0108] Preferably, the length of the first floor 141 is 8588mm and the width of the first floor 141 is 1160mm.

[0109] Fifth Implementation Method

[0110] Reference Figure 7 The main difference between the base frame 100 of the first embodiment and the base frame 100 of the fifth embodiment is that the base frame 100 includes a second bottom crossbeam 580 and two first floorboards 141.

[0111] In detail, two first floorboards 141 are arranged along the length direction D1 and form a joint 142 extending along the width direction D2. The two ends of the second bottom crossbeam 580 are connected to the two bottom side beams 110. The edges of the first floorboards 141 forming the joint 142 overlap with the second bottom crossbeam 580, thereby allowing the second bottom crossbeam 580 to support the edges of the joint 142 formed by the two first floorboards 141, making the installation of the two first floorboards 141 more stable.

[0112] Optionally, the colloid can also be applied between the top surface of the second bottom beam 580 and the bottom surface of the first floor 141, creating a sealed connection between them and reducing the accumulation of microorganisms on the base frame 100. Because the joint 142 has two layers of colloid, the depth within the joint 142 is reduced, further minimizing the accumulation of microorganisms.

[0113] Optionally, the length of the first floor 141 is 2900mm to 2920mm, and the width of the first floor 141 is 2310mm to 2330mm. This allows the base frame 100 according to the fifth embodiment to have the second bottom crossbeam 580 installed, but compared to existing containers, the installation of the floor center beam 370 is eliminated, which also reduces the weight and cost of the container.

[0114] Preferably, the length of the first floor 141 is 2905mm and the width of the first floor 141 is 2320mm.

[0115] Sixth Implementation Method

[0116] Reference Figure 8 The main difference between the base frame 100 of the second embodiment and the base frame 100 of the sixth embodiment is that the base frame 100 includes a second bottom crossbeam 580 and two first floorboards 141.

[0117] In detail, two first floorboards 141 are arranged along the length direction D1 and form a joint 142 extending along the width direction D2. The two ends of the second bottom crossbeam 580 are connected to two bottom side beams 110 and are located along the length direction D1 on the side of the gooseneck main beam 260 near the first floorboards 141. The edges of the joint 142 formed by the first floorboards 141 are connected to the second bottom crossbeam 580, thereby allowing the second bottom crossbeam 580 to support the edges of the joint 142 formed by the two first floorboards 141, making the installation of the two first floorboards 141 more stable.

[0118] Optionally, the length of the first floor 141 is 4290mm to 4310mm, and the width of the first floor 141 is 2310mm to 2330mm. This allows the underframe 100 according to the sixth embodiment to have a floor beam 370 installed, but compared to existing containers, the installation of the floor beam 370 is eliminated, which also reduces the weight and cost of the container.

[0119] Preferably, the length of the first floor 141 is 4294 mm and the width of the first floor 141 is 2320 mm.

[0120] This utility model also provides a container, including the base frame 100 of the container described above. According to the container of this utility model, the first floor 141 forms at most one seam 142, which not only reduces the accumulation of microorganisms but also at least reduces the arrangement of the floor beams 370 or the second bottom crossbeams 580 in the container, thereby reducing the weight and cost of the container.
