DETAILED DESCRIPTION
[0008] Generally, electric vehicles are gaining popularity because of their low-cost of maintenance and lower emission. Typically, electric two-wheeled vehicles are gaining popularity for their ease of operation. Vehicles with step-through type frame assembly, the power unit including an electric motor may be swingably mounted to the frame assembly and the utility box is disposed above the power unit. Also, the power unit is enclosed by panels of the vehicle. The power unit which is an electronic motor is generally operated between 40-100 volts but at higher currents to meet the required power rating because of which it gets heated up due to the high current flowing through the conductors. Therefore, the power unit is subject to heating and due to poor ventilation the electric motor acting as power unit is heated up affecting the performance of the electric motor. Also, excessive heating may heat up the connections with polymer sleeves that could melt and also the electrical connections may be prone to failure. Therefore, there arises a requirement that a forced fluid cooling for heat dissipation is to be installed about the power unit. This eats away the compact layout of the vehicle and also complicates the power unit that requires accommodation of the cooling system. This in effect makes the vehicle heavier and bulkier negating that compact layout, which is one of the desired features of the vehicle.
[0009] Moreover, the vehicle includes plurality of high capacity batteries that are used to drive the power unit. The high capacity batteries are to be accommodated within the vehicle. Generally, the high capacity batteries are disposed either in the utility box portion of the vehicle or below the seat portion of the vehicle. This consumes the utility space of the vehicle. For example, once the user accommodates the high capacity battery packs in the vehicle, there lacks any other secure location that the user can use to store accessories/ protective devices like helmets. Also, in some electric vehicle the batteries are disposed in the front portion of the vehicle, whereby the drivability of the vehicle is affected, especially during braking. As during braking there is a dynamic brake transfer towards a front portion of the vehicle that could be leading to nose diving of the vehicle, which can be hazardous. Also, in some other vehicle, the power unit and high capacity batteries are disposed in a rearward portion of the vehicle. This adds more loads on the vehicle and conventionally the power unit is coupled to the rear wheel thereby requiring high power and torque to drive the rear wheel. Thus, the aforementioned and other conventional vehicles offer poor heat dissipation, poor ridabilty, bulkier layout, and poor efficiency.
[00010] Besides, a naked step-through type vehicle, which is generally called as moped, provides a compact layout. The power unit, which is the electric motor, is mounted to the frame assembly and is positioned in a front portion of the vehicle. However, the vehicle layout is such that there is no space for accommodation of high capacity batteries or additional accessories like helmet. Moreover, in such a vehicle the batteries are mounted at the step-through space that consumes the only additional storage space of the vehicle. In such vehicles, storage box may be mounted to lateral side of such vehicle is known. However, this affects the compact layout of the vehicle, as it increases the width of the vehicle offering poor ridabilty, especially to pillion rider. Also, the load on the rear is high as the high capacity battery packs are mounted to the rear portion of the vehicle. Moreover, mounting the batteries and routing of cables from the batteries to the power unit becomes complex as the cables require a U-shaped routing that increases the routing length and requiring the cables to be routed through frame and swing arm thereby making the cable prone to wear out of failure. For example, the U-shaped routing is required when the batteries are disposed in a rear portion of the vehicle and the electric motor is hub mounted as the wire is routed through the frame requiring longer cables that extend from the batteries take a U-shaped bend and then extend towards the electric motor. Also, the wire after the U-shaped routing passes about the swing arm making thereby adding more stress to the cable due to the U-shaped bend. Thus, the conventionally known vehicles offer poor layout that either offer additional storage space or compromise on additional storage space or offer compact layout but with poor additional storage space.
[00011] Thus, there is a need for providing an electric vehicle with a frame layout that addresses the aforementioned and other problems in the prior art. The vehicle should be capable providing an additional storage space along with accommodation of high capacity battery packs at the same time retain compact layout.
[00012] Hence, the present subject matter provides an electric vehicle with a frame member. The frame member includes a primary tube extending rearwardly downward from the steering support tube and then inclinedly rearward towards a rear portion of the electric vehicle. The frame member supports at least one storage unit disposed adjoiningly to the primary tube. Further, a secondary tube extends substantially horizontally rearward from said steering support tube. The primary tube and said secondary tube define an additional storage space therebetween.
[00013] The primary tube is capable of securely supporting at least one storage unit, which includes a second storage unit, is disposed below the primary tube. It is an advantage that the at least one storage unit is disposed substantially between a front wheel and a rear wheel of the vehicle thereby enabling optimum load distribution on the wheels. In other words, the at least one storage is disposed substantially at the central portion of the front wheel and the rear wheel. The term ‘front wheel’ may include one or more wheels of a saddle ride-type electric vehicle. Similarly, the term ‘rear wheel’ includes one or more rear wheels for a saddle ride-type electric vehicle.
[00014] It is a feature that a first storage unit is capable of being disposed at the additional storage space defined by the frame member. The first storage unit is also disposed substantially between the front wheel and the rear wheel of the electric vehicle. Further, the first storage unit is securely mounted to the vehicle since it is surrounded by the primary tube from the front, the at least one storage unit from the bottom, the primary tube from the rear, and the secondary tube from above, when viewed from side of the vehicle. Thus, the first additional storage space provides secure space for mounting accessories or auxiliary power sources or electrical components.
[00015] It is a feature that in one implementation, the second storage unit disposed below the primary tube is capable of accommodating at least one auxiliary power source. The first storage unit provides a first storage volume substantially greater than a second storage volume of the second storage unit whereby the first storage unit is capable of securely accommodating substantially a full-face helmet therein. Thus, the electric vehicle provides a compact layout that enables securing mounting of accessories like helmet.
[00016] In another implementation, the second storage unit includes a second storage volume substantially greater than a first storage volume of the first storage unit. Thus, the first storage unit capable of accommodating at least one auxiliary power source and the second storage unit is capable of securely accommodating substantially a full-face helmet therein. Thus, the frame member of the present subject matter provides flexibility of providing the first storage unit and the second storage unit with a volume as required by the user thereby providing ease of design.
[00017] It is a feature that the vehicle includes the electric motor that is hub mounted to at least one wheel of the vehicle and at least one auxiliary power source disposed substantially between the front wheel and the rear wheel in either the first storage unit or the second storage unit enables optimum cable routing between the electric motor and the at least one auxiliary power source.
[00018] Moreover, in another implementation, the electric motor being mounted to the primary tube is secured and disposed below the primary tube. The at least one auxiliary power source disposed substantially between the front wheel and the rear wheel of the electric wheel enables the power unit to be optimally supported by the frame member. Also, the cable routing between the electric motor and the at least one auxiliary power source can be kept optimum as the electric motor is in proximity to the auxiliary power source.
[00019] Additionally, the vehicle provides a compact layout as the first storage unit and the second storage unit are having width(s) substantially lesser than a width of the electric vehicle thereby providing a compact layout of the electric vehicle. The width of the electric vehicle is considering at least one widest components of the vehicle like an auxiliary storage unit or width between the foot pegs of the vehicle.
[00020] It is a feature that the electric vehicle includes the auxiliary storage unit mounted to the frame member located between the front wheel and the rear wheel of the electric vehicle. The auxiliary storage unit overlaps with at least a portion of the at least one storage unit and the additional storage space, and the frame member with the primary tube and the secondary tube optimally supports the loads.
[00021] A first storage unit is disposed at the additional storage space defined by frame member. A second storage unit is mounted to the primary tube and is disposed adjoiningly adjacent to the primary tube, wherein the second storage unit is disposed below the first storage unit.
[00022] In a preferred implementation, the second storage unit is dedicated battery storage unit. It is a feature of the present subject matter that the frame member provided is capable of supporting the first storage unit and the second storage unit.
[00023] It is a feature of the present subject matter that the electric vehicle is employed with an electric motor. The electric motor acts as the traction motor of the electric vehicle, and the electric motor is powered by plurality of batteries or the like.
[00024] However, in another implementation, the second storage unit is used for accommodating one or more accessories and the first storage unit disposed at the additional storage space is used as a battery storage unit.
[00025] It is a feature of the present subject matter that the first storage unit acts as storage unit for accessories, wherein the first storage unit is capable of accommodating a full-face helmet.
[00026] It is an aspect of the present subject matter that a width of the first storage unit and the second storage unit is lesser than or equal to the width of the electric vehicle. Therefore, it is an advantage that the electric vehicle provides a compact layout without affecting the width of the electric vehicle. It is yet another advantage that the aesthetics of the electric vehicle are retained providing a sleek layout. It is yet another advantage that pillion rider comfort is not compromised as the pillion rider can comfortably place his/her feet as the width of the vehicle is compact unlike in a vehicle with the storage unit provided in the lateral direction. Further, the electrical vehicle provides better aero-dynamics because of the sleek profile thereby reducing drag of the vehicle and at the same time the ease of operating the vehicle in heavy traffic conditions is improved.
[00027] It is a feature of the present subject matter that, in an implementation, the frame member is capable of supporting the electric motor disposed adjacent to the battery storage unit. It is an aspect that the electric motor is connected to rear wheel through a chain drive or a belt drive. It is an advantage that the need for external cooling can be eliminated as flowing air is used for cooling the batteries and electric motor that operate at higher currents.
[00028] It is another feature of the present subject matter that the electric vehicle provides at least two storage units that are securely accessible. Further, the storage units are accessible from at least one lateral side of the electric vehicle.

[00030] Moreover, the battery storage unit is mounted to the electric vehicle is at a location from the electric motor being mounted either to the primary tube or the wheel providing optimum routing and connection therebetween as the length of wiring from the substantial center to the wheel is less compared to U-shaped routings. It is yet another advantage that the electric motor and the battery storage unit are disposed at substantially at lower portion of the electric vehicle, maintaining center of gravity at a lower point, thereby improving stability.
[00031] It is an additional aspect that the electric vehicle provides optimum cooling of the storage unit especially in case of batteries being mounted to the storage unit thereby improving performance of the electric vehicle.
[00032] It is an additional advantage that the frame layout provides the storage unit between the front wheel and the rear wheel thereby providing improved weight distribution thereby proving better riding experience.
[00033] In an embodiment, the long axes of the first storage unit and the second storage unit are in line. Further, the long axes coincide with the lateral center of the electric vehicle. In another embodiment, at least one storage unit is disposed at an offset from the lateral center to balance center of gravity of the electric vehicle. Therefore, the at least one storage unit disposed substantially at the central portion of the front wheel and the rear wheel along with the offset still enables the user to access accessories or batteries disposed in the at least one storage unit as the at least one storage unit is still exposed in lateral direction thereby retaining the ease of access in lateral direction and cooling aspect due to the flowing air.
[00034] In yet another embodiment, the battery storage unit is detachable type.
