The present disclosure relates to a powered vehicle, and more particularly to a powered vehicle capable of transporting one or more physically limited passengers.
Automobile manufacturers do not currently mass-produce passenger vehicles specifically designed to transport passengers having physical limitations, either as a driver or a passenger. Consequently, mass-produced passenger vehicles are modified, or retrofitted, by a number of aftermarket companies dedicated to supplying vehicles to physically limited passengers. Such vehicles can be modified by removing certain parts or structures within a vehicle and replacing those parts with parts specifically designed to accommodate the physically limited passenger. For example, in one configuration, a van may be retrofitted with a ramp to enable a physically limited individual using a wheelchair to enter the vehicle without the assistance of another individual.
Other known level change devices for retrofitting a vehicle, such as a van, include wheelchair lifts, lift platforms, and lowered floor surfaces. In some instances, a door of an original equipment manufacturer (OEM) van may be enlarged or otherwise modified to permit entry of the physically limited individual through what is known as the assisted entrance. Once inside the vehicle, individuals may operate the vehicle as a vehicle operator or occupy locations designated for passengers. This may include, but is not limited to, a front passenger location or rear passenger locations.
Many motorized vehicles modified to include a ramp or lift for transporting physically limited passengers are passenger vans or buses. Minivans, or passenger vans, are often referred to as multi-purpose vehicles (MPVs), people movers, or multi-utility vehicles. At least in the United States, minivans are classified as light trucks or MPVs. In many instances, these vans have rear access doors on each side thereof that, when opened, define a door opening that can provide easy ingress and egress of a wheelchair.
Crossover and sport-utility vehicles have become popular due to their style and driving performance. Sport-utility vehicles are built off a light-truck chassis similar to passenger vans, whereas crossover or crossover utility vehicles are built from a passenger car chassis. Due to their build, crossover vehicles are often more fuel efficient than heavier, sport-utility vehicles and include other advantages over minivans and sport-utility vehicles. The modified vehicles are often diesel or gasoline-powered.
In one embodiment of the present disclosure, a powered vehicle includes a chassis having a front end and a rear end, and at least one front wheel and at least one rear wheel for supporting the chassis. The at least one front wheel defines a front axle and the at least one rear wheel defines a rear axle. A first portion of the vehicle defines an interior and a second portion of the vehicle is located outside of the interior. The first and second portions are at least partially separated by a wall. The vehicle includes a power system for propelling the vehicle, where the power system is located in the second portion. An HV battery of the power system is provided for producing electrical power to propel the vehicle. The battery is coupled to the chassis and located in the second portion.
In one example of this embodiment, the battery is located at least partially forward of the power system. In a second example, the battery is located at least partially above the power system. In a third example, the battery is located forward of the front axle. In a fourth example, the power system comprises an engine.

In a twelfth example, when the battery is in its raised position, an open space is formed between the battery and power system. In a thirteenth example, a radiator support cap includes a plurality of openings such that the first and second support brackets are removably coupled to the radiator support cap. In a fourteenth example, the radiator support cap includes a slot, a first open end and a second open end, the slot forming a first intake inlet, the first open end forming a second intake inlet, and the second open end forming a third intake inlet.
In a fifteenth example, an actuator assembly is coupled between the battery and the chassis. In another example, a cooling system is coupled between the interior of the vehicle and the battery, the cooling system being configured to move air from the interior to the battery to cool the battery. In yet another example, the cooling system includes a ducting port coupled to the wall and fluidly coupled to the interior, a duct coupler fluidly coupled to the ducting port for receiving air therefrom, and at least one fan for suctioning the air from the duct coupler. Here, the at least one fan is configured to blow the air from the duct coupler to a cooling duct coupled to the battery such that the air blown from the fan passes through the cooling duct and into the battery.
In a further example, a fan coupler is coupled between the duct coupler and the at least one fan. In yet a further example, a hose is coupled between the ducting port and the duct coupler. In still another example, the duct coupler comprises an inlet and at least two outlets, where one of the at least two outlets is coupled to the fan coupler. In yet another example, the second of the at least two outlets is coupled to a cooling duct. In a further example, the cooling duct is coupled between the duct coupler and a second duct coupler, the second duct coupler being coupled to a second fan. In still a further example, the second fan suctions air through the cooling duct and second duct cooler and blows the air into a second cooling duct coupled to the battery.
In another embodiment of the present disclosure, a method is provided for modifying an existing powered vehicle. Here, the vehicle includes a chassis, one or more wheels supporting the chassis, and a power system for propelling the vehicle in a travel direction. The method includes providing the vehicle with a first portion defining an interior cab and a second portion, the first portion and second portion being at least partially separated by a wall. The method also includes coupling an engine of the power system to the chassis in the second portion, and coupling a HV battery of the power system to the chassis in the second portion such that the battery is located at least partially forward of the engine.
In one example of this embodiment, the method includes coupling the battery at least partially above the engine in the second portion. In a second example, the method includes providing the one or more wheels with a front wheel defining a front axle of the vehicle, and coupling the battery to the chassis forward of the front axle. In a third example, the method includes providing the one or more wheels with a rear wheel defining a rear axle of the vehicle, and coupling an all-wheel drive unit to the chassis at or adjacent to the rear axle.
In a fourth example, the method includes providing the one or more wheels with a rear wheel defining a rear axle of the vehicle, and coupling a fuel tank to the chassis at or rearward of the rear axle.

As shown in
As shown, the vehicle 100 includes a front end 108 and a rear end 110. A conventional driver's seat and front passenger seat (not shown) are generally located towards the front end 108 of the vehicle 100, whereas a rear passenger seat (not shown) is generally located towards the rear end 110 of the vehicle. More specifically, the vehicle 100 may include an interior that comprises a front interior portion and a rear interior portion. In several embodiments, the driver's seat and front passenger seat may be located in the front interior portion, and at least one rear passenger seat may be located in the rear interior portion of the vehicle 100.
In some embodiments, the vehicle 100 may include a first or front passenger side door 112 located between the front wheels 104 and rear wheels 106 and provides access to a passenger for sitting in a front passenger seat (not shown) of the vehicle 100 adjacent to the driver. In this position, the passenger has a clear forward view of the road when compared to sitting in the rear passenger seat of the vehicle 100. Moreover, when seated, the passenger may be facing in a forward direction of travel. Further, in the illustrated embodiment of
In some embodiments, the first door 112 and second door 114 may be hingedly coupled to the frame 102 of the vehicle 100. In other embodiments, at least the second door 114 may be slidably coupled to the frame 102. In
As shown in
In one embodiment, the second door 114 of the vehicle in
Referring to
A second compartment 212 may be located to the rear of the first compartment 210. In one embodiment, the second compartment 212 may be located or defined between the B pillar and C pillar of the chassis 202. The second compartment 212 may also be located in the interior or cab of the vehicle 200. A second row of seats (not shown) may be located in the second compartment.
A third compartment 214 may be located at the rear end 206 of the vehicle 200, as shown in
In order to convert a conventional vehicle to one which is better able to accommodate a wheelchaired passenger, a floor 218 of the vehicle 200 may be lowered. The floor 218 may be dropped by a few inches in one embodiment. In another embodiment, the floor 218 may be dropped by up to 2 inches. In a further embodiment, the floor 218 may be dropped by up to 4 inches. In yet a further embodiment, the floor 218 may be dropped by up to 6 inches. In still another embodiment, the floor 218 may be dropped by six or more inches. With the floor 218 being lowered, the vehicle drivetrain including, but not limited to, the engine 216 and/or electric motor, transmission (not shown), and driveline (not shown) may be lowered from their standard height in the conventional vehicle.
In one embodiment, with the floor 218 being lowered, the body or chassis 202 of the vehicle 200 may be raised by adding one or more spacers at or near a front axle 220 and a rear axle 222 of the vehicle 200. The raising of the body or chassis 202 may provide additional headroom in the interior or cab of the vehicle 200 so that a wheelchaired passenger has more room to move about within. Moreover, the additional headroom allows a wheelchaired passenger to enter or exit the vehicle 200 more easily.
The powered vehicle 200 of
In some embodiments, the powered vehicle 200 may be a hybrid vehicle having a high voltage battery, or HV battery. The HV battery is not intended to be confused with a normal low voltage 12-volt battery system as is customary in many, if not most, conventional vehicles. In a conventional hybrid vehicle, the HV battery may be located below the vehicle floor 218 or underneath a passenger seat in either the first compartment 210 or second compartment 212. In one embodiment, the HV battery may be originally located in a first location 226 underneath a passenger seat between the front axle 220 and rear axle 222.
In the present disclosure, a method of modifying an existing or conventional hybrid vehicle may include moving the HV battery from its original location 226 to a location 228 in the engine compartment 208. In one embodiment, the HV battery may be located at least partially above the engine 216 and/or electric motor or other power system. In another embodiment, the HV battery may be located at least partially forward or in front of the engine 216 and/or electric motor or other power system. In a further embodiment, the HV battery may be located at least partially above and/or forward of the front axle 220. In yet another embodiment, the vehicle may include a firewall 902 (see
In an alternative embodiment, the HV battery may be located towards the rear end 206 of the vehicle 200. In some embodiments, locating the HV battery in the rear of the vehicle is less advantageous than when it is located in the front of the vehicle 200. First, the AWD electrical drive unit 224 is located in the rear of the vehicle 200 and this may require relocation. In some embodiments, the AWD electrical drive unit 224 may be aligned coaxially along the rear axle. In other embodiments, the AWD electrical drive unit 224 may be positioned rearward of the rear axle. In yet other embodiments, the AWD electrical drive unit 224 may be positioned forward of the rear axle. In any event, the AWD electrical drive unit 224 may be located towards the rear of the vehicle and positioned near the rear axle. In addition, a fuel tank 232 (e.g., a liquid or gas fuel tank) may be located in the rear of the vehicle 200. The fuel tank 232 may be positioned rearward of the AWD electrical drive unit 224, for example, in one embodiment. In other embodiments, the fuel tank 232 may be positioned partially aligned with the rear axle. In some embodiments, the fuel tank 232 may be positioned adjacent to the rear axle. In further embodiments, the fuel tank 232 may be located either partially above or below the AWD electrical drive unit 224. With the AWD electrical drive unit 224 and fuel tank 232 coupled to the rear of the chassis, additional weight of the HV battery can overload the rear axle 222.
In another embodiment, the HV battery may be located in the engine compartment 208 but at least partially below the engine 216 and/or electric motor or other power system. While this allows for better weight distribution and rear seat capacity in the vehicle 200, the clearance between the HV battery and the underlying ground is reduced. It may be undesirable for an object to contact the HV battery as this can damage the HV battery and/or the vehicle.
Thus, if the HV battery is located upfront in the engine compartment 208 and at least partially above the engine, this can better balance the weight distribution across the vehicle 200. The modification of the vehicle by raising the frame or chassis 202 enables or at least partially creates the additional space above the engine 216 and/or electric motor or other power system for the HV battery. Moreover, the AWD electrical drive unit 224 and fuel tank 232 can be located in the rear of the vehicle 200 and the location of the HV battery upfront allows for one or more passengers in the rear of the vehicle 200, i.e., more capacity for rear seating with the HV battery upfront. This placement also better protects the HV battery. For example, in this location, the surrounding frame and firewall can protect passengers in the interior or cab of the vehicle 200 in the event of an accident. In some embodiments, with the HV battery located near the engine and/or electric motor or other power system, the HV battery may gain additional capacity in colder temperatures due to heat being dissipated from the engine.
The HV battery may also include a high voltage cable 230 or harness, as shown in

In one embodiment, the vehicle 200 may include a radiator support 310 at the front end 204 thereof. The radiator support 310 may be the original or conventional support. In other embodiments, a new or modified radiator support may be used. The radiator support may be configured to couple to a radiator (not shown). In the illustrated embodiment, a radiator support bracket 312 may be provided and coupled to the radiator support 310. The radiator support bracket 312 may be new structure incorporated with the vehicle 200 to assist with moving the HV battery to the engine compartment 208.

In other embodiments, the cooling duct 908 may receive air or other cooling fluid from a fan or other device (e.g, the radiator). In any event, the cooling duct 908 may have a first end and a second end. At the first end, the cooling duct 908 may be coupled to a first duct coupler 910. At the second end, the cooling duct 908 may be coupled to a second duct coupler 918.
In some embodiments, a flexible hose 912 may be coupled between the first duct coupler 910 and a first fan coupler 914. A fan (not shown in
In one embodiment, the second duct coupler 918 may be coupled to a second fan coupler 920 which includes a defined outlet 922 through which air or other cooling fluid may be suctioned from the cooling duct 908 via another fan (not shown). The other fan (not shown) may be coupled to the second fan coupler 920 via fasteners or other known mechanism.
In several embodiments, the first and second fan couplers may also be known as reducers. The reducers may be used to restrict or otherwise control the flow of air or other cooling fluid. In other embodiments, the fan couplers are not reducers and do not restrict or otherwise control the flow of air or cooling fluid.
In one embodiment depicted in
A fan (not shown) may be coupled to the inlet 1102 of the second cooling duct 1100. Moreover the fan may be coupled to the second fan coupler 920 such that the fan is capable of drawing air or other cooling fluid through the second fan coupler 920 and out of its outlet 922 and pushed through the inlet 1102 and into the second cooling duct 1100 to cool the HV battery 800.
In the embodiment of
As the fans 1204 are running, they may pull or suction airflow or other cooling fluid from the cab area 900 or from a remote location. In this embodiment, air from the cab 900 may be pulled through the ducting port 906 via a first flow direction 1106. It is noted that the airflow from the cab area 900 to the HV battery 800 is in a generally forward direction 1104. As the air flows through the ducting port 906 in the first flow direction, it may flow into a hose (not shown) which is coupled between the ducting port 906 and the second duct coupler 918. The fluid flow may flow in a second flow direction 1108 through an inlet of the second duct coupler 918 via an inlet.
In some embodiments, the second duct coupler 918 may include an inlet and an outlet. In other embodiments, the second duct coupler 918 may include an inlet and a plurality of outlets. In the embodiment of
At the same time, air or cooling fluid may also flow through the second outlet of the second duct coupler 918 into the cooling duct 908 along a fourth flow direction 1112. The air of cooling fluid may flow through the cooling duct along a fifth flow direction 1114 before it flows through the first duct coupler 910, the hose 912, and the first fan coupler 914. The first fan 1204 may draw or suction the air or cooling fluid through the first fan coupler 914 and then push or blow the air or cooling fluid into the first cooling duct 802 where it is able to cool the HV battery 800.
In some embodiments, the cooling air or other fluid may also be used to cool the engine 216 or other components of the power system 1300 (see
