A support frame assembly configured to strengthen an upper frame portion of a frame of a vehicle, comprising a first frame member having a first end and a second end, and a second frame member having a first end and a second end, wherein both the first ends of the first and second frame members are configured to couple to a front half of the frame and the second ends of the first and second frame members are configured to couple to the front half of the frame to strengthen the upper frame portion, at least one of the first and second ends of each of the first and second frame members including at least one mechanically coupled joint configured for coupling each of the first and second frame members to the front half of the frame.

Provided in this disclosure is a method of fabricating a backpack truck box, including a step of forming first and second patterned members from sheet material. Each of the patterned members includes multiple edges defining a first panel and a second panel each with one or more opposing tabs formed contiguously on opposing edges of each of panels. One or more bending operations are performed upon each of the opposing tabs to form first and second side portions extending at a predetermined angle from each of the panels. The side portions of the first panel are welded to respective corresponding side portions of the second panel to produce a welded backpack truck box housing.

A quasi-cylindrical cargo container is formed of a plurality of rigid, curved panels together forming first and second semi-cylindrical shells, and a plurality of rigid, flat extension panels bridging the first and second semi-cylindrical shells. A method of manufacturing the container includes forming the first and second semi-cylindrical shell from the curved panels, forming the quasi-cylindrical shell from the first and second semi-cylindrical shells and the flat extension panels, forming collars conformably encompassing the quasi-cylindrical shell, constricting the collars to compress joints formed at abutting edges of pairs of adjacent panels, rolling the shell and collars sequentially to bring the joints to a lower position, welding inside seams of the joints when at the lower position, removing the collars, rolling the shell sequentially to bring the joints to an upper position, and welding outside seams of the joints when at the upper position.

An embodiment upper body inner panel assembly of a vehicle includes a front inner panel and a rear inner panel disposed at a front and a rear of an upper body of the vehicle, respectively, wherein the upper body includes a plurality of pipes, wherein each of the front inner panel and the rear inner panel comprises a left part and a right part coupled to each other, and wherein the left part and the right part of the front inner panel and the left part and the right part of the rear inner panel are disposed in intersecting directions.

A body frame and a vehicle having the same are provided. The body frame includes: a transverse beam, provided with a transverse sliding groove; a longitudinal beam, connected with the transverse beam and provided with a longitudinal sliding groove; and a joint, disposed at a junction of the transverse beam and the longitudinal beam and mounted to the transverse beam by a transverse rivet and to the longitudinal beam by a longitudinal rivet. The transverse rivet is slidably mated with the transverse sliding groove, and the longitudinal rivet is slidably mated with the longitudinal sliding groove.

A method of manufacturing a cylindrical cargo container includes: providing a plurality of rigid panels together formable into a cylindrical shell; forming a first semi-cylindrical shell from a first set of the panels; forming a second semi-cylindrical shell from a second set of the panels; forming the cylindrical shell from the first semi-cylindrical shell and the second semi-cylindrical shell; forming a collar conformably encircling the cylindrical shell; constricting the collar to compress joints formed at abutting edges of pairs of adjacent panels; rolling the cylindrical shell and collar to bring respective joints of pairs of panels to a lower position, and welding an inside seam of the joint when at the lower position; removing the collar from the cylindrical shell; and rolling the cylindrical shell to bring respective joints of pairs of panels to an upper position, and welding an outside of the joint when at the upper position.

A semi-trailer has a rear frame with a post extending vertically at a side of the rear frame adjacent a rear end of a trailer side wall. A joint is disposed between the post and the side wall rear end. The joint has a first portion that receives a portion of the rear end of the side wall and a second portion offset inward from the first portion that receives a portion of the post. At least one fastener extends through the portion of the post and the second portion of the joint, without extending through the exterior surface of the side wall.

Provided herein is a shock deflecting wall panel and beam assembly, beam, and truck trailer using the same. The trailer wall panel assembly comprises at least one wall panel and at least one beam, wherein the at least one beam is configured to be received and retained in the at least one wall panel. The beam comprises at least one edge, a first beam corner, a second beam corner and a third beam corner, a first arm, an intermediate section, and a second arm, wherein the first and second arms are substantially parallel to one another, and the beam is configured to be substantially vertically extending.
