And, each underfloor energy storage unit assembly has a plurality of unit module installation areas, a longitudinal dimension of which extending in the longitudinal direction of the motor vehicle is standardized and each of which is designed to receive at least one respective standardized energy storage unit module.

An embodiment structure for mounting hydrogen storage tanks for a vehicle includes a chassis frame including a first frame and a second frame spaced apart from each other and a cutting area, and a hydrogen storage tank assembly inserted into the cutting area in a height direction of the chassis frame and configured to support at least one hydrogen storage tank, wherein the hydrogen storage tank assembly includes a first member and a second member each being fastened to the chassis frame.

A vehicle underbody structure includes a pair of rockers that are provided on both vehicle width direction sides of a vehicle underbody and extend in a vehicle front-rear direction, a battery that is disposed centrally in a vehicle width direction center between the pair of rockers and is disposed above a vehicle floor and on the lower side of a seat, a fuel tank that is disposed in the vehicle width direction center between the pair of rockers and is disposed under the vehicle floor and further toward a rear side of the vehicle than the battery, and a waste pipe that is coupled to a drive unit provided at a vehicle front side of the battery and extends in the vehicle front-rear direction between the battery and one of the rockers.

There is provided a high pressure container including a plurality of container bodies, each of the container bodies housing a fluid in a huh pressure state and being able to release the fluid through a release portion, (ii) opening section that is linked to the container bodies, and that opens at or above a predetermined opening temperature to release the fluid inside the container bodies, and (iii) a cover member that straddles the plurality of container bodies, that covers at least a portion of the plurality of container bodies, that is able to withstand a temperature of no less than the opening temperature, that is linked to the opening section, and that is capable of transmitting heat to the opening section.

A vehicle floor structure may include a floor disposed on a bottom portion of a vehicle body; a plurality of tank mounting members attached to a bottom surface of the floor; and a plurality of hydrogen tanks mounted on the plurality of tank mounting members, wherein each tank mounting member is aligned to extend in a longitudinal direction of the vehicle, the plurality of tank mounting members is spaced from each other in a width direction of the vehicle, each tank mounting member has a plurality of lower recessed portions provided in a lower portion thereof, and at least predetermined upper portions of the hydrogen tanks are received in the lower recessed portions of the tank mounting members, respectively.

A vehicle body rear portion includes a vehicle body floor and a fuel tank. The vehicle body floor has a tire storage area that is hollowed downward. The fuel tank is supported by a lower surface of the vehicle body floor on a forward side of the tire storage area. A stiffener is attached to the vehicle body floor at a forward position of the tire storage area. The stiffener extends along a vehicle body forward/rearward direction and reinforces an upper region of the fuel tank of the vehicle body floor.

A motor vehicle has a pressure vessel unit, the pressure vessels of which are arranged on both sides of a recess or depression in a passenger compartment floor.

A vehicle lower structure includes: a battery pack having first and second battery units and a battery cover; and a fuel tank that is arranged on a vehicle rear side to be higher than the first and second battery units. At positions under a floor panel, the first and second battery units are arranged on both sides in a vehicle width direction of a propeller shaft. The battery cover has a coupling section that couples first and second battery accommodation sections. The coupling section couples the first and second battery accommodation sections such that a vehicle rear side thereof is higher than the first and second battery accommodation sections, extends in the vehicle width direction at a position above the propeller shaft, and is arranged next to a vehicle front side of the fuel tank.

A pressure vessel mounting structure includes: a manifold including a discharge gas passage branching from a general passage via which a container body communicates with a valve; a fusible plug valve configured to close the discharge gas passage and to, when the fusible plug valve is melted, open the discharge gas passage such that the high-pressure gas is discharged; a case including a bottom face portion covering the container body and the manifold from below in the vehicle up-down direction, the case including a bead placed near the fusible plug valve, the bead being formed by protruding a part of the bottom face portion upward in the vehicle up-down direction; and a communicating opening via which a space under a floor of a vehicle communicates with the fusible plug valve, the communicating opening being formed in a part of the bead, the part facing the fusible plug valve.

A work machine, more particularly a wheeled loader, having a cab for the operator of the work machine, wherein the work machine has a drive which can be operated with hydrogen and that one or more tanks for receiving hydrogen are provided, wherein components for receiving the tanks are provided, wherein the tank or tanks are arranged below the cab and, when the work machine is viewed from above, next to the cab of the work machine, wherein the components for receiving the tanks do not have a direct mechanical connection to the cab, and that an armor is provided which partially or completely surrounds the tank.
