Vehicle chassis with interchangeable performance packages and related methods. are disclosed herein. An example vehicle chassis disclosed herein includes a frame including a first chassis portion including a cavity, a battery platform coupled to first chassis portion, and a first subframe couplable within the cavity, the first subframe including a first motor and a first suspension assembly, and a second subframe couplable within the cavity, the second subframe including a second motor and a second suspension assembly, the second motor having a greater power than the first motor, the second suspension assembly having a greater stiffness than the first suspension assembly.

A support plate and reinforcement member may be mounted within a hollow side sill between a rocker and crossmembers for a vehicle framework. The support plate may include flanges along either edge and a straight, projecting face between the flanges. The reinforcement member, mounted on the support plate proximate to an outer surface of the side sill, may include flanges along either edge and a wavy projecting face between the flanges. Contact portions of the projecting face for the reinforcement member may contact an interior of the side sill at regions aligned with where the side sill mounts to the crossmembers, with intervening portions of the projecting face, in areas adjacent energy absorbing crush cans, extending less far from the flanges. The intervening portions may also be laterally offset from the contact portions, to provide larger weld areas.

Electric vehicles are disclosed herein. In certain embodiments, an electric vehicle includes a front cage, a rear floor, an intermediate section, a utility cabinet, and a flatbed. In other embodiments, an electric vehicle includes a front cage, a rear floor, an intermediate section, and a flatbed. In some embodiments, the front cage at least partially defines an operator cabin, the rear floor is positioned rearward of the front cage in a longitudinal direction, and the intermediate section is disposed at least partially between the front cage and the rear floor in the longitudinal direction.

A military vehicle includes a chassis, an axle, a suspension system, and a driveline. The chassis includes a passenger capsule, a front module coupled to a front end of the passenger capsule, and a rear module coupled to a rear end of the passenger capsule. The axle is supported by the rear module. The suspension system is positioned between the rear module and the axle. The suspension system includes a first gas spring, a second gas spring, a first damper, and a second damper. The first damper and the second damper are cross-plumbed to provide a fluid body roll control function. The driveline is configured to drive the axle. The driveline includes a component having a housing that functions as a structural component of the rear module. The first gas spring, the second gas spring, the first damper, and the second damper are directly coupled to the housing.

A mobile carrier includes a carrier controller configured to check an amount of charge of a main battery of a vehicle through communication with a vehicle controller, to check an amount of charge of a carrier battery, to compare the amounts of charge of the main battery and the carrier battery when the carrier is installed in the vehicle and to control mutual charging of the main battery and the carrier battery.

Described herein are various systems and processes for vehicles for delivery of real-time, on-demand orders for perishable goods, and operations thereof. The vehicles may each include a plurality of different modules that couple to a chassis. The modules may include battery modules, drive modules, cargo modules, and other modules. Each drive module may include wheels and motors and steering mechanisms that control the wheels. A plurality of such modules may be disposed on the chassis. The modules may be disposed on different portions of the chassis and be given different operational commands accordingly. Furthermore, operation of the vehicle may be adjusted based on the cargo carried by the vehicle.

An example vehicle frame disclosed herein includes a convex surface to face the ground when the vehicle frame is in a first operating position and face away from the ground when the vehicle frame is in a second operating position, the vehicle frame rotatable about a longitudinal axis of the vehicle frame between the first and second operating positions, and a concave surface opposite the convex surface, the concave surface to face away from the ground when the vehicle frame is in the first operating position and face the ground when the vehicle frame is in the second operating position.

The present invention provides an electric vehicle platform according to an embodiment of the present invention. The electric vehicle platform includes two side frames extending from front wheels to rear wheels of a vehicle, a plurality of support frames connecting the side frames, a driving motor disposed between two front wheels or between two rear wheels, a battery configured to supply power to the driving motor, a controller configured to control the driving motor and the battery, and a cover assembly connected to the side frames and the support frames so as to cover the driving motor, the battery, and the controller. Here, the cover assembly is divided into a first area defined above the front wheels, a second area defined between the front wheels and the rear wheels, a third area covering the battery and the controller, and a fourth area defined above the rear wheels.

Methods, apparatus, systems and articles of manufacture are disclosed for multi-position wheel assembly mounts. An example vehicle frame disclosed herein includes apertures adjacent to each of a plurality of wheel assembly locations on the vehicle frame, and a wheel assembly mount at each of the wheel assembly locations, the wheel assembly mount having protrusions extending toward the vehicle frame and positionable in the apertures in a first position to provide a first ride height of the vehicle frame and a second position to provide a second ride height of the vehicle frame, the first ride height less than the second ride height.
