An embodiment vehicle body coupling structure of a vehicle that includes an underbody and an upper body coupled to the underbody includes a front back beam assembly provided on a front side of the underbody, a first mounting part provided on a front side member of the upper body and coupled with the front back beam assembly, and a first body coupling part provided on the front back beam assembly and engaged with the first mounting part.

A center upper frame nodal connection fabrication comprising a top surface, a bottom surface opposite the top surface, two side surfaces, a front surface having a plurality of integral planes oriented at angles relative to each other, and a rear surface opposite the front surface. The top surface, the bottom surface, and the two side surfaces can be weldably attached to each other and the front and rear surfaces to form a structure of the center upper frame nodal connection fabrication. The integral planes of the front surface are configured to weldably attach to respective elongate support members of a space frame. The rear surface is configured to weldably attach to a center upper frame connection casting of the space frame.

The present disclosure provides an electric vehicle comprising a chassis, a front axle and a rear axle spaced apart and coupled to the chassis, and a battery frame assembly coupled to the chassis between the front axle and the rear axle. The battery frame assembly comprises a plurality of transversely extending members and a plurality of longitudinally extending members, wherein the plurality of transversely extending members and the plurality of longitudinally extending members define a matrix of battery pack receptacles configured to receive at least one battery pack. The battery frame assembly is configured to deflect torsionally in response to torsional deflection of the front axle relative to the rear axle.

The present invention provides an overlapping bonded structure in which breaking of a bonded section at holes formed during bonding can be prevented when an overlapping section formed by overlapping a plurality of meal plate members is bonded by means of a mechanical bonding means or a friction stir spot-welding means. This overlapping bonded structure, in which overlapping portions of a plurality of plate members are spot-welded at a plurality of bonded sections by means of a mechanical bonding means or a friction stir spot-welding means, and in the bonded sections a hole into which the mechanical bonding means is inserted or a hole formed during the spot-welding by the friction stir spot-welding means exists in at least one plate member, is characterized in that a cutout recess is formed between adjacent bonded sections, from an end portion of the overlapping section in the bonded-section direction, in the overlapping section of at least one of the plate sections, and when the inner diameter of the hole is K, an inside bottom portion of the cutout recess is formed at a position having a depth of K or greater from the end portion of the overlapping section.

A vehicle includes a floor plate defining a front and a back of the vehicle, wall sections to receive vehicle loading and transfer the vehicle loading to the floor plate, and a fluid delivery assembly supported by the floor plate. The fluid delivery assembly includes an intake manifold that resides at the back, an outlet that resides at the front, and a set of lateral conduits extending between the intake manifold and the outlet to laterally convey fluid entering the intake manifold from a fluid source to the outlet for delivery to a fluid target. Accordingly, the back may connect to the fluid source and the front may deliver the fluid thus keeping the vehicle sides and top available for other uses. Moreover, the low isolated placement of the fluid delivery assembly safeguards the fluid delivery assembly and provides a low center of gravity for vehicle stability.

A heavy duty power distribution system is provided that includes an electric vehicle control module and a cable interface coupled with the electric vehicle control module. The electric vehicle control module includes an electric vehicle frame assembly and a power distribution component coupled with the electric vehicle control module frame assembly. The electric vehicle control module frame assembly is configured to support components of the electric vehicle control module on a vehicle frame rail, e.g., behind a cab thereof. A cowling is disposed around the power distribution component. The cable interface has a first junction and a second junction which are configured to connect the power distribution component with a power source and a load respectively.

A body tie-down for a chassis includes a mounting plate, a spring assembly, and a rigid member. The mounting plate is configured to fixedly couple with a body frame member with one or more fasteners, each of the fasteners including a bolt and a collar that are swaged together. The rigid member is configured to couple with the mounting plate through the spring assembly to provide a semi-resilient joint between the rigid member and the mounting plate, the rigid member configured to fixedly couple with a frame.
