Abstract: Embodiments herein relate to a chassis structure of a vehicle, such as an at least partially electrically-powered vehicle, and a side assembly for use in conjunction with the chassis structure. The chassis may include a set of frame rails spaced apart by rigid cross-members. A set of rigid braces may be coupled to the outer portions of each of the frame rails, and a side assembly may be coupled on each side of the chassis to a respective set of the braces. At least one of the side assemblies can have at least one sealable internal volume, with an inlet port and an outlet port allowing fluid accessibility. The sealable internal volume can be used to store compressed air or coolant used by the vehicle, and other internal volume(s) can be used to house vehicle electrical and/or plumbing lines.

Abstract: Embodiments herein relate to a battery support structure for an electric vehicle, assemblies with the same, and methods of manufacturing, integrating, and using the same, among other things. In embodiments, a support structure for use on an electric vehicle includes a pair of frame rails and a battery case with a bottom coupled to the frame rails. The battery case is coupled to the frame rails at a location below the frame rails, e.g., with resilient bushings held between the battery case and the frame rails by brackets extending below the frame rails, and away from the battery case.

Abstract: An amphibian operable in land and marine modes includes a hull, having a discontinuity, and a retractable wheel or track drive assembly at least partially located in the discontinuity. A wheel or track drive of the at least one retractable wheel or track drive assembly is retracted above a lowest point of the hull when operating in marine mode, and the wheel or track drive is protracted below the lowest point when operating in land mode. The hull is a planing V hull having a forward bow section defining a frontal bow surface/area across a beam of the hull. The discontinuity is provided in the forward bow section, and the wheel or track drive of the retractable wheel or track drive assembly is located ahead of and in front of at least a portion of the frontal bow area when protracted.
