Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

In addition, repeated reference numerals or symbols may be used in different embodiments. These repetitions are only for the purpose of simply and clearly describing the present invention, and do not represent any correlation between the different embodiments or structures discussed.

In various drawings of the present application, for the convenience of illustration, some sizes of structures or parts are exaggerated relative to other structures or parts, and thus, are only used to illustrate the basic structure of the subject matter of the present application.

As shown in FIGS. 1 to 5 , the present invention provides a container 100 with an external device 50. Generally, the container 100 is in a rectangular parallelepiped shape and includes a bottom frame 10, two side walls 30 extending upward from the bottom frame 10, a front wall, a rear wall, and a top wall. In the present invention, the side walls 30 are preset to extend in the length direction of the container 100, and the end walls are preset to extend in the width direction. In the present invention, the container 100 is configured with a top-opening door, so the top wall is a door body 40.

The bottom frame 10 of the container 100 includes a bottom side beam 2 arranged along the edge of the bottom frame 10, and the side wall 30 extends upward from the bottom side beam 2. The bottom frame 10 is recessed inward from the outer edge of the bottom side beam 2 to form a recessed structure 3; in the first state, the external device 50 can be accommodated in the recessed structure 3 and does not protrude from the outer edge of the bottom side beam 2.

Therefore, in the present invention, by providing the recessed structure 3 on the bottom side beam 2, the external device 50 can be accommodated in the recessed structure 3 and does not protrude from the outer edge of the bottom side beam 2. Overall, even if the container 100 is equipped with the external device 50, the overall size does not change, so that the standard size can still be met. During the transportation and assembly process of the container 100, the external device 50 will not affect the container 100, but the container 100 can still use the function of the external device 50, and the production and transportation efficiency can be greatly improved.

Of course, the base frame 10 also includes a main board 1 , which is a steel floor, and the bottom side beam 2 is arranged along the edge of the main board 1 in the length direction.

As described above, the recessed structure 3 is formed on the bottom frame 10 by being recessed inward from the outer edge of the bottom side beam 2. Therefore, the size of the recessed structure 3 varies according to the size of the external device 50. Specifically, the present invention provides two specific embodiments.

In the first embodiment, the recessed structure 3 is disposed on the bottom side beam 2 and is recessed inward from the outer edge thereof, and the recessed depth of the recessed structure 3 is less than the width of the bottom side beam 2. In the first embodiment, the recessed structure 3 is only disposed on the bottom side beam 2 and does not penetrate the bottom side beam 2 transversely. In this embodiment, it is applicable to external devices 50 with smaller structures.

In the second embodiment, the recessed depth of the recessed structure 3 is not less than the width of the bottom side beam 2. As shown in FIG3 , the bottom side beam 2 is usually slightly higher than the main board 1 of the bottom frame 10 in the height direction, and the recessed structure 3 extends on the bottom frame 10. Therefore, if the recessed depth of the recessed structure 3 is not less than the width of the bottom side beam 2, two situations are also included.

One is that the recessed depth of the recessed structure 3 is equal to the width of the bottom side beam 2, then the recessed structure 3 just penetrates the bottom side beam 2, and the external device 50 can be accommodated in the recessed structure 3, or it can also extend into the container 100 without interfering with the main board 1.

Second, as shown in FIG1 , if the depth of the recessed structure 3 is greater than the width of the bottom side beam 2, the recessed structure 3 also extends to part of the main board 1. In this case, the space of the recessed structure 3 for accommodating the external device 50 is larger, and the external device 50 can be further extended in the vertical direction.

Since, in both of the above two specific embodiments, a recessed structure 3 needs to be provided on the bottom side beam 2, the structure of the bottom side beam 2 is bound to be not a complete side beam structure. Therefore, in the present invention, the bottom frame 10 further includes a reinforcing member 21, as shown in FIG2 , the reinforcing member 21 includes a first fixing portion 211, a connecting portion 212, and a second fixing portion 213 connected in sequence; in the length direction of the container 100, the connecting portion 212 spans the recessed structure 3, and the first fixing portion 211 and the second fixing portion 213 are both fixed to the inner edge of the bottom side beam 2.

That is, the reinforcing member 21 has at least a first fixing portion 211 and a second fixing portion 213 fixed to the inner edge of the bottom side beam 2, and respectively fixed to both sides of the recessed structure 3, thereby strengthening the bottom side beam 2 and preventing the recessed structure 3 on the bottom side beam 2 from affecting the strength of the bottom side beam 2, thereby ensuring the safety and stability of the bottom frame 10 of the container 100.

2 , the recessed structure 3 extends into the reinforcing member 21. Specifically, the recessed structure 3 includes a first recessed portion 31 disposed on the bottom side beam 2 and a second recessed portion 32 formed by further recessing from the first recessed portion 31 toward the connecting portion 212.

In this specific embodiment, firstly, the width of the connecting portion 212 is sufficient and can form a second recessed portion 32, so that the reinforcement member 21 can further provide a storage space for the external device 50, and the connecting portion 212 can still span across both sides of the recessed structure 3, thereby playing a role in strengthening the bottom side beam 2.

As shown in Fig. 2, the reinforcing member 21 is in a U-shaped structure. Of course, if the recessed structure 3 provides enough space for the external device 50 and does not need to extend into the reinforcing member 21, the reinforcing member 21 is completely fixed against the bottom side beam 2, which can also achieve the purpose of the present invention.

In addition, the reinforcing member 21 is also fixed to the main board 1. In this specific embodiment, the recessed structure 3 not only extends in the transverse direction, but also in the longitudinal direction, and penetrates the bottom side beam 2 from top to bottom. The recessed structure 3 not only extends into the connecting portion 212, but also extends into the main board 1. Thus, the recessed structure 3 also includes a third recessed portion (not numbered) extending from the first recessed portion 31 further into the main board 1. The third recessed portion is flush with the inner wall of the second recessed portion 32 in the vertical direction.

Furthermore, the recessed structures 3 are arranged in pairs on the two bottom side beams 2; the bottom frame 10 also includes a reinforcing beam 22, and the two ends of the reinforcing beam 22 are respectively connected to the two reinforcing members 21 arranged in pairs. As shown in FIG1 , the recessed structures 3 are arranged in pairs and a total of four are arranged on the two bottom side beams 2, so that four external devices 50 can be accommodated. Furthermore, the recessed structures 3 on the two bottom side beams 2 are arranged correspondingly, and the reinforcing beam 22 extends in a direction parallel to the end wall.

Of course, the reinforcing beam 22 is also fixed on the main board 1, so that the reinforcing beam 22 can further provide support for the reinforcing member 21, ensuring that the bottom side beam 2 is disconnected by the recessed structure 3 but still has high stability, ensuring the safety of the overall structure of the container 100 and ensuring safe transportation.

As shown in Fig. 3, the base frame 10 may be provided with a weight-reducing hole 101 inside to reduce the weight of the container 100. Specifically, the base frame 10 has a crossbeam and a longitudinal beam arranged on the main board 1, and the weight-reducing hole 101 may be selectively arranged in the crossbeam and the longitudinal beam.

In addition, as shown in Figures 4 and 5, the container 100 includes a telescopic arm 7, and the external device 50 is fixed on the telescopic arm 7; in the above-mentioned first state, the telescopic arm 7 is in a telescopic state, and the external device 50 is accommodated in the recessed structure 3; in the second state, the telescopic arm 7 extends outward, and the external device 50 protrudes outward from the recessed structure 3 and protrudes laterally from the bottom side beam 2.

That is, in the present invention, the external device 50 can be accommodated in the recessed structure 3, and can also be extended horizontally through the telescopic arm 7 and then protrude to the outside of the bottom side beam 2. The external device 50 in the present invention can be placed in the recessed structure 3 when not in use, and can also be extended to the outside of the bottom side beam 2 through the telescopic arm 7 when in use, so as to facilitate the user to use. The telescopic arm 7 can be a cylinder, etc.

In this embodiment, the external devices 50 are fixed to both ends of the telescopic arm 7, and the telescopic arm 7 is also arranged parallel to the reinforcing beam 22. When the telescopic arm 7 is extended, the external devices 50 at both ends can be extended outward at the same time; similarly, when the telescopic arm 7 is shortened, the external devices 50 at both ends can be moved inward at the same time and accommodated in the recessed structure 3.

At least four recessed structures 3 are provided, and at least four external devices 50 are also provided and correspond to the recessed structures 3. That is, each recessed structure 3 corresponds to an external device 50. The external device 50 includes a support frame 5 and a support member 6 that can extend downward from the support frame 5; in the third state, the support member 6 can extend downward from the support frame 5 and protrude from the bottom of the base frame 10.

In the third state, the support member 6 extends downward and protrudes from the bottom of the chassis 10, then, multiple support members 6 extend downward at the same time, and the support member 6 can lift the container 100, so that the chassis 10 of the container 100 is off the ground, which is more conducive to the placement of the container 100 in different ground environments and more conducive to loading and unloading. Of course, the external device 50 has a first state in which it is accommodated in the recessed structure 3, a second state in which it extends laterally outward from the recessed structure 3, and a third state in which its support member 6 further extends downward.

In this embodiment, four external hanging devices 50 are provided, as shown in FIG1 , and four recessed structures 3 are also provided, two of which are provided at the middle of the length direction of the container 100 near the front wall, and the other two are provided at the rear wall. Therefore, when the support member 6 is extended downward, the four support members 6 are subjected to force together, and the container 100 can be stably lifted.

The external hanging device 50 also includes a controller for controlling the extension length of the support member 6. If the ground on which the container 100 is placed is flat, the four support members 6 can be controlled to extend to the same length, so that the container 100 can be lifted as a whole; if the ground on which the container 100 is placed is not flat, the extension length of the four support members 6 can be determined according to the leveling device on the container 100 to ensure that the container 100 is in a horizontal state after the four support members 6 are extended.

In addition, as described above, the container 100 also includes the side wall 30. If the external device 50 extends a long length in the vertical direction, the side wall 30 also needs to be recessed inward to form a receiving portion (not shown), and the receiving portion corresponds to the recessed structure 3 in the vertical direction; the external device 50 can also be accommodated in the receiving portion. As shown in Figure 5, since the external device 50 includes a support member 6, and the support member 6 is accommodated in the support frame 5 in the first state, the length of the support frame 5 in the vertical direction is relatively long. In the present invention, the side wall 30 is also recessed to form the receiving portion for accommodating the support frame 5.

In the above, the present invention introduces the case where the external device 50 is a support frame 5 and a support member 6. Of course, if the external device 50 is other equipment, such as lifting equipment, air-conditioning cabinet, etc., the purpose of the present invention can also be achieved.

In summary, the present invention provides a container 100 with an external device 50, wherein, by providing a recessed structure 3 on the bottom side beam 2, the external device 50 can be accommodated in the recessed structure 3 and does not protrude from the outer edge of the bottom side beam 2. Overall, even if the external device 50 is installed on the container 100, the overall size does not change, so that the standard size can still be met. During the transportation and assembly process of the container 100, the external device 50 will not affect the container 100, and the production and transportation efficiency can be greatly improved.

In addition, the present invention provides two specific structural embodiments of the recessed structure 3, which can be adapted to the sizes of different external devices 50. The present invention also provides specific structures of the reinforcing member 21 and the reinforcing beam 22, which can still ensure greater structural strength and stability when the recessed structure 3 is provided on the bottom side beam 2, thereby ensuring the basic cargo loading and transportation functions of the container 100.

In addition, the external device 50 in the present invention is specifically a support frame 5 and a support member 6 that can extend downward along the support frame 5. The support member 6 can extend downward to lift the container 100, which helps to place the container 100 on an uneven ground, helps to load and unload goods, and improves transportation efficiency.
