Land vehicles, modular systems for forming monocoques of land vehicles, and methods of forming monocoques of land vehicles using modular systems are disclosed herein. In certain embodiments, the land vehicles are provided as delivery vehicles and/or utility vehicles. A land vehicle includes a monocoque supporting a plurality of wheels to permit movement of the vehicle relative to an underlying surface in use of the land vehicle.

A deck plate assembly for a truck chassis having first and second elongated frame members. Elongated rail brackets are mounted on the upper ends of the first and second frame members. Each of the rail brackets has an elongated slide slot formed in the inner sides thereof. A storage box and an airline box are positioned between the first and second frame members. A storage box support frame is slidably mounted in the slide slots of the rail brackets so as to be positioned over the storage box. The storage box is bolted to the storage box support frame. An airline box support is slidably mounted in the slide slots of the rail brackets so as to be positioned over the airline box. The airline box is bolted to the airline box support. Metal deck sections may also be slidably mounted in the rail brackets.

A method of assembling a unibody vehicle includes securing a cab back panel of a cab back panel directly to an upturned flange of a cargo box floor. A unibody vehicle assembly according to another exemplary aspect of the present disclosure includes, among other things, a cab back panel, a cargo box floor, and a passenger compartment floor. The cab back panel is secured directly to the cargo box floor. The cab back panel provides a back wall of a passenger cab and a front wall of a cargo area.

An assembly for utility truck bodies having metal and/or composite reinforcement(s) and/or foam reinforcements and/or honeycomb reinforcements and/or wood reinforcements encapsulated within a thermoformed thermoplastic, or thermoset or fiber-reinforced thermoset walking surface floor structure of the truck bed assembly or other composite floor structure with attachable components and junctions, e.g., sidepack(s), and methods of making the same are provided.

Provided is a vehicle lower-part structure including: a pair of center side members; a main battery that is arranged between the pair of center side members; a support cross member connecting the pair of center side members and supporting a front end of the main battery from below; a pair of support brackets that protrude toward a center in a vehicle width direction from the pair of center side members at positions closer to a rear other end with respect to the support cross member, and support the main battery; and a cable drawn out from the main battery.

A vehicular body structure includes a polymeric deck panel. The deck panel includes an adjacent ridge and valley with a leg shared therebetween, a crossbeam footprint crosswise to the adjacent ridge and valley, and a rib extending along the adjacent ridge and valley. Outside the crossbeam footprint, the rib extends along the ridge, approaching the crossbeam footprint, the rib extends along the leg into the valley, and across the crossbeam footprint, the rib extends along the valley.

A vehicular body structural arrangement includes a polymeric deck panel. The deck panel includes corrugations, a crosswise crossbeam footprint and, along a partial length of the crossbeam footprint, two features for securing a crossbeam thereto. The corrugations include an adjacent ridge and valley. The features include a first feature having a first direction along the deck panel, and a second feature having a second direction toward the deck panel. The first feature includes a unitarily-formed web projecting normally to the deck panel past the ridge, and a rivet nut installed to the web against a backing facing the first direction. The second feature includes a unitarily-formed stanchion behind the web projecting normally to the deck panel from inside the valley, and a threaded insert seated in the stanchion facing the second direction.

A floor securing apparatus comprises a riser slot formed in a floor riser, extending from a top surface toward a bottom surface of the floor riser. The floor riser is configured to support a floor sheet. The apparatus further includes a key including a locking head and at least one anchor tab, where the key is slidable into the riser slot and configured to engage a portion of the floor sheet when slid into the riser slot to prevent vertical movement of the floor sheet relative to the floor riser.

A utility vehicle includes a plurality of ground engaging members and a frame supported by the plurality of ground engaging members. The frame assembly extends generally along a longitudinal axis of the utility vehicle. The utility vehicle further includes a front seating section coupled to the frame. The front seating section is configured to support an operator and a first passenger. Additionally, the utility vehicle includes a rear seating section coupled to the frame. The rear seating section is configured to support a second passenger and a third passenger. The rear seating section has an angled panel configured as a dead pedal for the second and third passengers, and a portion of the rear seating section extends forwardly into the front seating section.
