DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, the present invention will be further described in conjunction with embodiments and drawings.

It will be more apparent for the container body structure of the present invention to exhibit advantages in maintenance process. In the present invention, the container body structure will be divided into six separate individual parts, i.e., a roof sheet, a right side panel, a right side panel, a floor, a rear wall and a front wall. Each of the six parts can be detached from the container body by a simple operation, and thus maintenance and replacement on any components and elements may be performed in one of the six parts. Accordingly, the maintenance of the container body is considerably facilitated and simplified, since the container body does not have to be maintained as a whole and each part can be repaired and/or maintained separately.

Referring to FIG. 1, the container body structure of the vehicle in the present invention also comprises six parts, i.e. a roof sheet 1, a left side panel 2, a right side panel 3, a floor 4, a rear wall 5 and a front wall 6, each of which is a separate individual part, and the container body structure of the vehicle in the present invention is also formed by assembling the roof sheet 1, the left side panel 2, the right side panel 3, the floor 4, a rear wall 5 and the front wall 6.

Each of the roof sheet 1, the left side panel 2, the right side panel 3, the floor 4, a rear wall 5 and the front wall 6 may be a individual frame part, or may be in a form of a foaming sandwich plate (not illustrated in the drawings) which comprises an outer plate, an inner plate and a foaming layer disposed between the outer plate and the inner plate.

In order to conveniently perform assembly and disassembly among the roof sheet 1, the left side panel 2, the right side panel 3, the floor 4, a rear wall 5 and the front wall 6, connectors which may cooperate with each other may be provided at peripheries thereof, such that the roof sheet 1, the left side panel 2, the right side panel 3, the floor 4, a rear wall 5 and the front wall 6 can be assembled together by means of these connectors.

During assembling the container body structure of the present invention, the connectors of the present invention may be assembled together by fasteners, or may be welded or adhered together, or assembled together by snap-in elements. In the present invention, there is no limit to the assembling manner of the connectors, as long as assembly and disassembly of the roof sheet 1, the left side panel 2, the right side panel 3, the floor 4, a rear wall 5 and the front wall 6 can be conveniently realized, so that assembly and disassembly of the container body can be realized by the assembly and disassembly of the connectors.

The roof sheet 1, the left side panel 2, the right side panel 3, the floor 4, a rear wall 5 and the front wall 6 themselves each may be formed with respective connectors, and may be assembled together by fasteners, so that the roof sheet 1, the left side panel 2, the right side panel 3, the floor 4, a rear wall 5 and the front wall 6 may be assembled not only at a local site but also at another different site after transportation in package, which consequently realize the purpose of segmental transportation and rapidly assembly.

As an alternative solution, the connectors of the roof sheet 1, the left side panel 2, the right side panel 3, the floor 4, a rear wall 5 and the front wall 6 may be not affiliated to any one part, but may be additionally installed on the roof sheet 1, the left side panel 2, the right side panel 3, the floor 4, a rear wall 5 and the front wall 6, or may be connected during assembling the container body. Nevertheless, the connecting function of the connectors exhibited can not be changed.

Hereinafter, the roof sheet 1, the left side panel 2, the right side panel 3, the floor 4, a rear wall 5 and the front wall 6 themselves formed with connectors will be described. In accordance with the above description, it will be apparent to the person skilled in the art that it also can be realized that connectors are not affiliated to any one parts.

In order to facilitate the assembly of the roof sheet 1, the left side panel 2, the right side panel 3, the floor 4, a rear wall 5 and the front wall 6, side wings may be oppositely extended between each two adjacent connectors, and these side wings may be overlapped with each other and be used for assembling fasteners.

FIG. 2A illustrates connections between the front wall and the left side panel as well as between the rear wall and the left side panel. FIG. 2B is a cross-section diagram illustrating a front wall corner post connector of the present invention. FIG. 2C is a cross-section diagram illustrating a side plane front end connector of the present invention.

As shown in FIG. 2A, two front wall corner posts, which are provided on the left and right sides of the front wall 6, are formed into front wall corner post connectors (only a front wall corner post connector 61 formed by a left front wall corner post is illustrated in the Drawings), respectively; two rear wall corner posts, which are provided on the left and right sides of the rear wall, are formed into rear wall corner post connectors (only a left rear wall corner post connector 51 formed by a left rear wall corner post is illustrated in the Drawings), respectively; and side panel front end connectors 21 and side panel rear end connectors 22 are provided at the front and rear ends of the left side panel 2 and the right side panel 3, respectively.

As shown in FIG. 2A, each of two rear wall corner post connectors 51 (only one is illustrated in the drawings) is made of a pipe with a square cross section, and each has a side wing 511 extending toward the side panel rear end connector 22.

When the right side panel 2, the right side panel 3, the rear wall 5 and the front wall 6 need to be assembled together, the side wings 611 of the two front wall corner post connectors 61 and the side wings 211 of the side panel front end connectors 21 are overlapped with each other correspondingly and assembled together by fasteners, such as rivets and the like; and the side wings 511 of the two rear wall corner post connectors 51 and the side wings 221 of the side panel rear end connector 22 are overlapped with each other correspondingly, and assembled together by fasteners, such as rivets and the like.

Since the left panel 2, the right panel 3, the front wall 6 and the rear wall 5 are separate individual structures before being assembled into a container body, it is merely required to partially position and perform fastening by means of rivets during assembly process. Upon performing the assembly process, the left side panel 2 and the right side panel 3 may overlap the front wall 6 and the rear wall 5 respectively, which is beneficial to control the overall size of the container body, efficiently reduce the difficulty of assembling and improve productivity effect. The connectors shown in FIGS. 2A, 2B and 2C not only function as frame structural members of the left panel 2, the right panel 3, the front wall 6 and the rear wall 5, but also function as connectors for connecting the left side panel 2 and the right side panel 3 with the front wall 6 and the rear wall 5. The connectors used in the present invention are not limited to the structural form or outline dimensions as shown in FIGS. 2A, 2B and 2C.
