Referring to fig. 1 and 2, a cargo box connector 100 according to an embodiment of the present invention includes a supporting portion 10, a limiting plate 30, and a side plate 50. The bearing part 10 has a bearing surface C and a supporting surface Z opposite to each other in the first direction. The limiting plate 30 is disposed on the bearing surface C and has a limiting surface X perpendicular to the bearing surface C. The side plate 50 is disposed on the support surface Z and has a stop surface D perpendicular to the support surface Z, and the stop surface D is spatially intersected with the limiting surface X. The spacing surface X and the bearing surface C form a first space S (as shown in fig. 3) for receiving the cargo box beam 2031, the bearing surface C is configured to support the cargo box beam 2031, and the limiting plate 30 is configured to fixedly connect to the cargo box beam 2031. The stop surface D and the support surface Z form a second space P (shown in fig. 4) for accommodating the frame rail 201, and the load-bearing part 10 and the side plate 50 are both used for fixedly connecting with the frame rail 201.

The cargo box connection member 100 accommodates the frame rails 201 in the second space P, and is fixed by the bearing portions 10 and the side plates 50, and further accommodates the cargo box cross member 2031 in the first space S, and is supported by the bearing surface C, and fixed by the limit plate 30. In this manner, the cargo box is indirectly secured to frame rails 201 via cargo box connection 100. The spacing surface X and the stop surface D are intersected in space to adapt to the frame rails 201 and the cargo box cross beam 2031 in different spatial directions. The limiting plate 30 is fixed to the cargo box cross beam 2031, on one hand, the limiting surface X limits the longitudinal movement of the cargo box along the longitudinal direction of the frame longitudinal beam 201, that is, the longitudinal deviation of the cargo box during traveling, especially during acceleration, deceleration, starting and braking, is prevented, and on the other hand, the limiting plate can strengthen the structure of the cargo box cross beam 2031. The side plates 50 are fixed to the frame rails 201, so that on one hand, the container connecting member 100 can be prevented from moving transversely perpendicular to the longitudinal direction of the frame rails 201 through the stop surfaces D, and further, the container arranged on the container connecting member 100 is indirectly prevented from shifting transversely during driving, particularly during turning, and on the other hand, the connection strength of the container connecting member 100 and the structural strength of the frame rails 201 can be further enhanced. Therefore, the bearing part 10, the limiting plate 30 and the side plate 50 of the cargo box connecting piece 100 can realize multi-angle stable fixation of the cargo box of the vehicle, the types of parts required by the cargo box connection are simplified, and particularly, large-size and high-weight structures like cargo box connecting longitudinal beams and U-shaped bolts are not needed, so that the weight of the truck is reduced. In addition, thanks to the reduction of the types of parts, the complexity of assembly is reduced, and the installation efficiency of the container is improved.

Further, the bearing part 10 includes a main body 11 and a supporting plate 13, the main body 11 and the supporting plate 13 are adjacently connected along a second direction perpendicular to the first direction, one side surface of the main body 11 and the supporting plate 13 in the first direction jointly serves as a supporting surface Z, and the other side surface of the main body 11 in the first direction serves as a bearing surface C. In the first direction, the orthographic projection of the side plate 50 simultaneously intersects the orthographic projection of the main body 10 and the orthographic projection of the support plate 13. The support plate 13 can increase the connecting area of the cargo box connecting member 100 and the frame rail 201, and improve the reliability of connection.

Specifically, in the first direction, the thickness of the main body 11 is greater than the thickness of the support plate 13. The body 11 is configured to be positioned between the frame rails 201 and the bed rail 2031 and to provide the main support, and the support plate 13 provides the main support for the body 11, and the relatively thinner design contributes to weight reduction.

Further, the cargo box connector 100 further includes a reinforcing bar 70, the limiting plate 30 is located on a side of the main body 11 adjacent to the support plate 13 in the second direction, and the reinforcing bar 70 is connected between the support plate 13 and the limiting plate 30. When accelerating, slowing down, starting or braking, the packing box because inertia can directly exert very big pressure for limiting plate 30 certainly, also can indirectly transmit simultaneously for backup pad 13, consequently has higher requirement to intensity between them, and strengthening rib 70 can improve limiting plate 30 and backup pad 13's structural strength effectively, helps it to resist the pressure that is brought by packing box inertia.

In this embodiment, the main body 11, the supporting plate 13, the limiting plate 30, the side plates 50 and the reinforcing ribs 70 are integrally formed, and the integrally formed structure is favorable for accelerating the production rhythm and improving the connection stability of each part.

In some embodiments, the main body 11 and the support plate 13 are both provided with a first connection hole 15, and the first connection hole 15 is used for connecting with the frame rail 201. The connecting member can stably connect the carrying portion 10 with the frame rail 201 through the first connecting hole 15, and the first connecting hole 15 of the main body 11 is disposed in the hollow area so as not to affect the carrying surface C.

Further, the side of the main body 11 as the bearing surface C has a hollow groove 111 recessed toward the supporting surface Z, and the first connection hole 15 of the main body 11 penetrates through the groove bottom of the hollow groove 111 and the supporting surface Z (as shown in fig. 5). Likewise, a partial region of the supporting plate 13 is hollowed out. Under the prerequisite that satisfies the strength requirement, the fretwork helps further reducing the weight of packing box connecting piece 100.

More specifically, a guiding structure 111 extending from the bearing surface C to the periphery of the first connection hole 15 is configured in the hollow groove 111, and the guiding structure 111 is used for guiding a connector to pass through the first connection hole 15 into the first connection hole 15. So, the connecting piece can get into the first connecting hole 15 that is located the fretwork groove 111 bottom through guide structure 111 fast, reduces the assembly degree of difficulty.

In some embodiments, the side plate 50 includes a first section 51 connected to the main body 11 and a second section 53 connected to the supporting plate 13, and the widths of the first section 51 and the second section 53 in the second direction are gradually narrowed in a direction away from the supporting surface Z. The quality of the side plate 50 is reduced as much as possible while ensuring the transverse limiting function. In addition, the whole container connecting piece 100 is subjected to topological optimization, so that the structure, the shape and the size of the container connecting piece 100 are more reasonable on the premise of meeting the strength requirement, and the lightweight is further realized.

Further, the first section 51 and the second section 53 of the side plate 50 are both provided with a second connecting hole 55, and the second connecting hole 55 is used for connecting with the frame rail 201. The limit plate 30 is opened with a third connection hole 31 for connecting with the cargo box beam 2031. The side plates 50 are connected with the frame longitudinal beams 201 through connecting pieces matched with the second connecting holes 55, and the limiting plates 30 are connected with the cargo box cross beam 2031 through connecting pieces matched with the third connecting holes 31.

In the embodiment, the connecting piece is a bolt, the bolt is simple to connect and assemble and stable in connection, and welding stress caused by welding can be avoided. It is understood that in other embodiments, a rivet connection or a welding connection without an opening may be used, and the specific number of the first connection hole 15, the second connection hole 55 and the third connection hole 31 may be determined according to the requirement, and is not limited herein.

Referring to fig. 6, the present invention further provides a truck, which includes the container connecting member 100, a frame and a container, wherein the container connecting members 100 are a plurality of containers, and the container is fixed on the frame by the plurality of container connecting members 100.

Specifically, the cargo box includes a box body (not shown) and a plurality of cargo box cross members 2031 disposed at the bottom of the box body, and the frame includes two frame rails 201. The plurality of cargo box connectors 100 are arranged in pairs, with two cargo box connectors 100 of each pair of cargo box connectors 100 being disposed opposite each other on either side of a cargo box rail 2031 and connected to a frame rail 201. The paired cargo box connectors 100 may provide more comprehensive spacing for each cargo box rail 2031, better meeting the full-scene requirements of acceleration, deceleration, starting, braking, or turning.

It can be understood that each cargo box beam 2031 may be connected to one frame rail 201 by only one cargo box connector 100, and the mounting directions of the cargo box connectors 100 of different cargo box beams 2031 may be changed in a staggered manner, which may also have a certain effect of increasing the omni-directional limiting effect. In other embodiments, the two limiting plates 30 of the cargo box connector 100 are parallel and spaced apart, and the two limiting plates 30 and the support surface Z together form the first space S for accommodating the cargo box beam 2031. Thus, the two limiting plates 30 on one container connecting piece 100 can simultaneously form the limiting in the front and back directions.

More specifically, the frame rail 201 is an open-sided channel structure and includes an upper wing 2011, a lower wing 2012, and side wings 2013. The support surface Z of the cargo box attachment 100 contacts the upper wing surface 2011 and the side plate 50 contacts the side wing surface 2013. The channel shaped frame rail 201 also helps to reduce the overall weight of the truck.

In addition, in order to achieve normal operation, the truck should further include a cab, a power assembly, wheels, and other components that are the same as those of a conventional truck, and the truck frame specifically includes a frame cross member, and so on, which are not described herein again.

When the cargo box connecting piece 100 is used, the cargo box connecting piece 100 is firstly fixed on the frame longitudinal beam 201 primarily through the matching of the first connecting hole 15 of the bearing part 10 and the upper wing surface 2011 of the frame longitudinal beam 201, and then the cargo box connecting piece 100 is further fixed through the matching of the second connecting hole 55 of the side plate 50 and the side wing surface 2013 of the frame longitudinal beam 201. After the cargo box connectors 100 are fixed, the cargo box beams 2031 of the cargo box are aligned with the carrying surfaces C of the paired cargo box connectors 100, and the cargo box beams 2031 and the cargo box connectors 100 are fixed through the third connecting holes 31 of the limiting plates 30, so that the cargo box is fixed to the vehicle frame through the cargo box connectors 100. Although only one connecting structure of the container connecting pieces 100 is adopted, the container connecting pieces 100 arranged in pairs can simultaneously provide the position limitation on the longitudinal sides and the transverse sides for the containers, so that the containers are stably and reliably connected, the structure of the truck for connection is simplified while deviation is avoided, and the weight burden of the truck is reduced due to the light weight of the container connecting pieces 100.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
