[0063] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and arrangements of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can refer to the same reference numerals and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or arrangements discussed.

[0064] In some embodiments of the present application, as Figure 1 As shown in FIG. 10, a container is involved, which is a semitrailer container. A container front frame is also involved, which is used to be installed on the semitrailer container.

[0065] The container front frame in the present embodiment is used in non-standard containers such as semitrailer containers, which can meet the demand of expansion while avoiding collision with the tractor 120 during turning. In addition, it also needs to be able to be lifted from the top or side end of the container, so as to ensure the convenient lifting of the container.

[0066] As shown in FIG. 10, a container is involved, which is a semitrailer container. A container front frame is also involved, which is used to be installed on the semitrailer container. Figure 9 、 Figure 10 As shown in FIG. 10, a container is involved, which is a semitrailer container. A container front frame is also involved, which is used to be installed on the semitrailer container.

[0067] The semitrailer container is connected with the tractor 120 through the hitch 110.

[0068] The tractor 120 drags the semitrailer container to run through the hitch 110.

[0069] Specifically, the hitch 110 is connected with the tractor 120. The hitch 110 does not rotate relative to the tractor 120.

[0070] Specifically, the hinge point 111 is arranged on the hitch 110. The hitch 110 is hinged with the semitrailer container at the hinge point 111. The hitch 110 and the semitrailer container can rotate relative to the hinge point.

[0071] In the process of turning the tractor 120, the tractor 120 does not rotate relative to the hitch 110, and the hitch rotates relative to the semi-trailer container.

[0072] In order to avoid the semi-trailer container from colliding with the tractor 120 and the hitch 110 in the process of turning relative to the tractor 120 and the hitch 110, the semi-trailer container does not collide with the tractor 120 and the hitch 110 in the range with the hinge point 111 as the center and the maximum turning radius as the radius according to the relative position of the tractor 120 and the hitch 110 relative to the hinge point 111.

[0073] Since the height of the hitch 110 is lower than that of the semi-trailer container, the hitch 110 does not collide with the semi-trailer container.

[0074] Therefore, in the process of turning the semi-trailer container relative to the tractor 120, the semi-trailer container may collide with the tractor 120. The maximum turning radius can be determined according to the closest distance of the tractor 120 relative to the hinge point 111.

[0075] Specifically, the maximum turning radius is not less than the closest distance of the tractor 120 relative to the hinge point 111.

[0076] Therefore, the container front frame position needs to be located in the area formed with the hinge point 111 as the center and the maximum turning radius as the radius.

[0077] In order to increase the volume of the semi-trailer container as much as possible under the premise of ensuring that the container front frame does not collide with the tractor 120, the container front frame includes a front frame support unit 200 and an expansion unit 300, as shown in Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The container front frame includes a front frame support unit 200 and an expansion unit 300, as shown in

[0078] The expansion unit 300 is connected to the front frame support unit 200 near the side of the tractor 120.

[0079] Furthermore, in the process of turning relative to the hinge point 111, the expansion unit 300 does not exceed the area formed with the hinge point 111 as the center and the maximum turning radius as the radius, so as to avoid the semi-trailer container from colliding with the tractor 120.

[0080] In order to further increase the volume of the expansion unit 300 without causing the semi-trailer container to collide with the tractor 120, the expansion unit 300 includes an expansion body 310 and first and second avoiding portions 320 and 330, as shown in Figure 1 .

[0081] The expansion unit 300 is connected to the inside of the container through the front frame support unit 200, thereby increasing the volume of the container.

[0082] The first avoiding part 320 and the second avoiding part 330 are respectively formed on both sides of the expansion body 310.

[0083] During the rotation of the semi-trailer container relative to the hinge point 111, the first avoiding part 320 and the second avoiding part 330 rotate relative to the hinge point 111, and the expansion body 310 will not exceed the area formed by the hinge point 111 as the center and the maximum turning radius as the radius.

[0084] In some embodiments, the first avoiding part 320 and the second avoiding part 330 can adopt an arc shape, the center of the arc is the hinge point 111, and the radius is less than the set maximum turning radius.

[0085] In some other embodiments, the first avoiding part 320 and the second avoiding part 330 can adopt a straight line form, and the distance between any point on the first avoiding part 320, any point on the second avoiding part 330 and the hinge point is less than the set maximum turning radius, thereby ensuring that the first avoiding part 320 and the second avoiding part 330 will not exceed the area formed by the hinge point 111 as the center and the maximum turning radius as the radius during the rotation relative to the hinge point 111.

[0086] The relative distance between the first avoiding part 320 and the hinge point 111 is not greater than the relative distance between the tractor 120 and the hinge point 111;

[0087] The relative distance between the second avoiding part 330 and the hinge point 111 is not greater than the relative distance between the tractor 120 and the hinge point 111.

[0089] A side end lifting hole is formed on one side of the corner fitting close to the side end of the container. The side end lifting hole is used for lifting the container from the side end of the container.

[0090] A top end lifting hole is formed on one side of the corner fitting close to the top end of the container. The top end lifting hole is used for lifting the container from the top end of the container.

[0091] In some embodiments of the present application, the corner fitting can adopt the existing corner fitting mold, thereby saving cost while meeting the lifting demand.

[0092] The top beam 210, the first front corner post 230, the bottom beam 220 and the second front corner post 240 are sequentially arranged and connected by a plurality of corner pieces to form a front frame support unit 200 of a rectangular frame structure.

[0094] The two ends of the first front corner post 230 are connected to the top beam 210 and the bottom beam 220 through the first corner piece 250.

[0095] The side end lifting hole formed in the first corner piece 250 is defined as a first side end lifting hole 251.

[0096] The top end lifting hole formed in the first corner piece 250 is defined as a first top end lifting hole 252.

[0098] The two ends of the second front corner post 240 are connected to the top beam 210 and the bottom beam 220 through the second corner piece 260.

[0099] The side end lifting hole formed in the second corner piece 260 is defined as a second side end lifting hole 261.

The two ends of the second front corner post extension 313 are connected to the top beam extension 314 and the bottom beam extension 315 through the first sealing plate 311, respectively. Thus, the capacity expansion body 310 is arranged to form a rectangular frame structure.

[0104] Specifically, the first front corner post extension 312 is arranged to extend from the first front corner post 230 towards the tractor 120.

[0105] Specifically, the second front corner post extension 313 is arranged to extend from the second front corner post 240 towards the tractor 120.

[0106] Specifically, the roof beam extension 314 is arranged to extend from the roof beam 210 towards the tractor 120.

[0107] Specifically, the bottom beam extension 315 is arranged to extend from the bottom beam 220 towards the tractor 120.

[0108] In some embodiments of the present application, the first front corner post extension 312 is arranged to be inclined relative to the first front corner post 230 towards the second front corner post 240 to form a first avoiding part 320.

[0109] In some embodiments of the present application, the second front corner post extension 313 is arranged to be inclined relative to the second front corner post 240 towards the first front corner post 230 to form a second avoiding part 330.

[0115] In this state, the locking holes of the first corner fitting 250 and the roof beam 210 on the same surface, and the locking holes of the first corner fitting 250 and the first front corner post 230 on the same surface are all located at the surface of the container front frame in the present embodiment, and can continue to be used for hoisting.

[0120] The first corner fitting 250 also has a lock hole on the surface facing the direction of the expansion unit 300. Since the lock hole is close to the roof beam extension 314 and the floor beam extension 315, the lock hole cannot be used for lifting. Therefore, a second sealing plate is connected to the lock hole in a sealed connection. The second sealing plate is used for sealing the lock hole.

[0127] The surface of the second corner piece 260 in the direction of the expansion unit 300 is also provided with a lock hole, and since the lock hole is close to the top beam extension 314 and the bottom beam extension 315, the lock hole cannot be used for hoisting. Therefore, a second sealing plate is sealingly connected at the lock hole. The second sealing plate is used for sealing the lock hole.

[0128] The bottom beam 220 and the bottom beam extension 315 are sequentially arranged along the first corner piece 250 and the first sealing plate 311.
