DETAILED DESCRIPTION
[013] Pollution from internal combustion engines has become a significant concern in recent times. Road transport vehicles generate large amount of pollutants which harms the environment. Efforts are being made to provide electric vehicles and hybrid vehicles which does not discharge harmful emissions. Electric vehicles provide a means for transportation that do not emit any harmful pollutants into the atmosphere as they run on batteries.
[014] Electric vehicles are provided with plurality of batteries being configured to be assembled in a frame assembly of a vehicle. The heating of the battery pack is a major issue as it not only reduces the efficiency of the battery but also causes discomfort to the user.
[015] In conventional design of a two wheeled vehicle operating at a high-speed range, the battery is assembled in a middle portion of a frame assembly of the vehicle. In such an arrangement, during riding condition, a rider is positioned in such a way that the femur region or thigh region of the rider comes into direct contact with the area of the frame assembly where the battery is disposed.
[016] During a running condition of the vehicle, the battery gets heated during charging and discharging which leads to increase in temperature of the battery Though the hot air is departed from a lower portion of the vehicle, however due to the mounting of body panels on a left side, and a right side and a top portion of the vehicle, maximum heat gets trapped inside the body panels of the vehicle and heat dissipation does not occur effectively. Simultaneously, the body panels covering the battery on all the three sides also gets heated up due to the high heat generated from the battery. This in turn causes discomfort to the rider by creating a hot sensation in the thigh region of the rider. Thus, an improved design to efficiently cool the battery is required.
[017] In conventional design, critical elements of a vehicle such as a battery is being covered by body panels/body panels. The body panels comprising two distinct layers. The first layer of the body panels is a plastic cover which protects the critical part elements and also provide sufficient insulation for the battery. The second layer of the body panels is a metallic layer which provides protection to the battery from any external collision and also provides an aesthetically pleasing look of the vehicle to the rider. Since, battery produces heat, the battery is packaged in a close environment, can ultimately result in the over-heating of the battery. Such overheating of battery in turn heats up the body panels along with the metallic cover. Furthermore, additional heat from an engine of the two wheeled vehicle causes the temperature of the body panels to increase. Since the leg of the rider is usually positioned on the sides of the vehicle while he is sitting on the vehicle, overheating of the cover frame in the current vehicles is a hindrance to the rider as the cover frame comes in direct contact with the customer’s thigh. Therefore, the heated cover frame makes the rider uncomfortable, especially around his thigh region.
[018] Furthermore, overheating of the battery causes the battery to drain out quickly and reduces the lifecycle of the battery. Consequently, if the battery suddenly drains during running condition of the vehicle, it can stop functioning of certain essential vehicle elements such as a self-start mechanism, safety systems, turn indicated devices, and a headlight. Since the rider is not aware regarding the quick rate of discharge of the battery, sudden disablement of vehicle elements such as the self-start mechanism, the safety systems, the turn indicated devices, and the headlight will bewilder the rider and also hamper the safety and security of the rider and nearby vehicles.
[019] Additionally, overheating of the battery beyond a certain temperature can lead to explosion of the battery. This can not only hamper the safety and security of the rider and the nearby vehicles but can be fatal. Hence, a cooling device to cool the battery is required to avoid explosion of the battery. The same is not preferred due to additional cost, addition of number of parts, space constraints in the vehicle layout.
[020] In a related art, an engine is mounted below a fuel tank assembly and an air intake structure is provided behind the engine under the fuel tank assembly. The inlet portion of the air intake structure opens towards a rear end of the vehicle and the outlet portion of the air intake structure is configured to supply air to an intake port of the engine to combine air and fuel mixture for combustion of the engine. Therefore, the air intake structure does not provide air to cool the battery which is mounted in the rear region of the frame assembly. Therefore, such an arrangement of an air intake structure provides cool air to aid in combustion of air and fuel mixture and does not enable cooling of the battery which causes discomfort to the rider due to extreme heat generated by the battery, that is being transmitted to the body panels of the vehicle.
[021] In another related art, an air intake structure is provided in a front portion of the two wheeled vehicle between a front cowl and a headlight. This arrangement provides cooling in the front region on the vehicle and does not provide sufficient air to cool the battery.
[022] In another related art, an air intake structure is arranged on the fuel tank assembly of the vehicle. The rear portion of the fuel tank assembly comprised of plurality of recesses for entry of air. The recesses being aligned towards an engine. This arrangement efficiently cools an engine which is located below the fuel tank assembly. However, this arrangement cannot cool a battery efficiently because the battery is located in a middle portion in the vehicle and is covered by the body panels. Further, this type of arrangement only provides localized cooling on the engine and does not provide cool air to any other parts of the vehicle. Thus, the heat generated during running condition of the battery remains trapped inside the body panels and thereby causes discomfort to the rider while riding the vehicle.
[023] In another related art, air vents or air intake structures are provided on the body panels, usually in form of a cut out. However, a cut-out portion only lets partial entry of cooling air and does not provide means to directly cool the battery from all sides, without compromising the compactness of the vehicle.
[024] Furthermore, the conventional air intake structures are designed without any ridges. The absence of ridges leads to entry of unwanted dust particles and also entry of heavy gushing rain during the running condition of the vehicle. Thus, the entry of dust particles or rain disrupts the functioning and efficiency of the engine. Hence, an improved design of an air intake structure is required to overcome the stated problem.
[025] Hence, it is an object of the present invention to overcome all the above stated and other related problems existing in the prior arts, with respect to cooling the battery in a vehicle efficiently as well as other problems of known art.
[026] It is further an object of the present invention to reduce discomfort to the rider due to heat generated by the battery.
[027] It is further an object of the present invention to provide to provide an air-guide structure which reduces entry of dirt and dust particles inside the vehicle.

This wedged shape profile provides a wider portfolio for entry of cool air without any resistance during vehicle running condition. The wedged shape profile also has plurality of ridges to provide sufficient entry of cool air at higher velocity and also prevent the entry of dust particles and rain droplets inside the battery. This arrangement prevents heating of the metallic cover due to the heat generation by the battery and thereby protecting the thighs of the rider while being seated on the vehicle. This arrangement also prevents entry of dirt and dust particles inside the battery and thereby enhancing the life of the battery.

[050] A pair of side rails (shown only right-side rail) (106) is configured to support a seat (not shown in figures). A rider and a pillion rider sit on the seat, the seat is inclined at an angle in the middle portion of the frame assembly (100). A primary side frame (110) extending inclinedly in a downward direction from a rear frame portion (112) and said seat rails (106). A secondary side frame (104) extend perpendicularly downwards from said main tube (108) and said seat rails (106). The seat rails (106), said primary side frame (110) and said secondary side frame (104) forms a triangular profile (114) at the intersection of said seat rails (106) with said secondary side frame (104), and at the intersection of said secondary side frame (104) with said primary side frame (110) and at the intersection of said primary side frame (110) with said seat rails (106). The triangular profile (114) in the frame assembly (100) supports a battery and a HECU unit, said battery being mounted in the downward portion of said triangular profile (114) of the frame assembly (100).
[051] Figure 2 illustrates a right-side view of body panels of the two wheeled vehicle, in accordance with an embodiment of the present subject matter. The frame assembly (100) of the two wheeled vehicle is protected through a body panels (204). The body panels (204) provides protection to all vehicle components from damage and distortion as well as provide aesthetic appeal for the rider. The first layer of the body panels (204) comprises of plastic, said plastic layer to provide insulation to vehicle components. The body panels (204) is further covered with a metallic layer over the plastic layer to improve aesthetic appeal and also provide strength and stability to arrest any forceful entry or collision from other vehicles? and thereby protect the internal components of the vehicle.
[052] The body panels (204) comprises a fuel tank assembly (200) and a battery covering unit (202) The battery covering unit (202) covers a battery (as shown in figure 3) and a HECU unit and provides sufficient protection from any external damage. The fuel tank assembly (200) has a top surface, a lower surface and a left surface and a right surface. The fuel tank assembly (200) is further covered by body panels (204) to protect the fuel tank assembly (200) from damages and prevent entry of dirt and dust particles into the fuel tank assembly.
[053] The battery covering unit (202) is mounted in the downward portion of the vehicle covering said triangular profile (114) of the frame assembly (100). The battery covering unit (202) is configured to be mounted on the primary side frame (110), seat rails (106) and a secondary side frame (104). The battery covering unit (202) forms a trapezoidal shape. The battery covering unit (202) further covers a rear end portion of an air-guide structure (208) which blows cooled air into the battery covering unit (202) for efficient cooling of the battery and thereby prevent discomfort to the rider in the thigh region by reducing heat dissipation in the battery covering unit (202). The air guide structure (208) is configured to be mounted on the lower surface of the fuel tank assembly (200). This arrangement provides an open location for the air guide structure (208) to access the influx of cool air in a large quantity during the running condition of the vehicle.
[054] The air-guide structure (208) is configured to be mounted in below the fuel tank assembly (200). The air-guide structure (208) when viewed from the front portion of the vehicle in a X-X’ (as shown in Figure 2) direction, provides natural cool air inlet for cooling the battery (as shown in Figure 3a). Furthermore, the air-guide structure (208) provides circulation of natural air for cooling of the battery (as shown in Figure 3a) and thereby reduce cost of implementing any other complicated mechanical or electrical means of cooling the air entered to be supplied to the battery (as shown in Figure 3a).
[055] Figure 3a illustrates a right-side view of vehicle components being mounted on the frame of the two wheeled vehicle, in accordance with an embodiment of the present subject matter. Figure 3b illustrates a right-side view of an air-guide structure on the frame assembly of the two wheeled vehicle, in accordance with an embodiment of the present subject matter. Figure 3a and 3b will be discussed together. A battery (300) is being covered by the battery covering unit (202). The battery (300) is mounted along a perpendicular direction Y-Y’ in the triangular profile (114) of the frame assembly (100). The air-guide structure (208) is mounted in the front portion of the vehicle and ends towards the middle portion of the vehicle, such that end portion of the one or more air guide structures (208) is disposed over the battery (300) and said battery (300) being covered by said battery covering unit (202). The battery (300) is further mounted using various fastening means such as screws, bolts, fixtures or by using snap fitting means.
[056] The air-guide structure (208) is configured to be mounted in the bottom portion of the fuel tank assembly (200). The air-guide structure (208) has a long-elongated tube-like structure. The elongated tube of the air- guide structure (208) comprises of a wedged air inlet portion on one end that allows the entry of the air when the vehicle moves in forward direction. The wedged profile of the inlet portion opens towards the front portion of the vehicle and thereby during running condition of the vehicle, high influx of cool air is achieved due to wider opening area of the wedged profile. Thus, maximum amount of cool air can enter from the wedged inlet portion. The other end of the elongated tube is an outlet portion, that is positioned in proximity to the top most portion of the battery (300). Such that the outlet portion directs the air received from the inlet portion to the top most region of the battery, ensuring that the battery is cooled substantially from all sides. Resultant to which the body panels along with the metallic cover part gets cooled and the rider’s thigh region does not feel heat and hence the rider is comfortable while riding the vehicle.
[057] Figure 4a illustrates a perspective view of the air-guide structure, in accordance with an embodiment of the present subject matter. Figure 4b illustrates a rear view depicting mounting details of the air-guide structure, in accordance with an embodiment of the present subject matter. Figure 4c illustrates an exploded view of the air-guide structure, in accordance with an embodiment of the present subject matter. Figure 4d illustrates an exploded view of the air-guide structure depicting mounting details, in accordance with an embodiment of the present subject matter. Figure 4a, Figure 4b, Figure 4c and Figure 4d will be explained together. The elongated tube-like structure of the air-guide structure (208) comprising an inlet portion (400) and an outlet portion (406) has a curvilinear shape. The curvilinear shape of the air-guide structure (208) enables efficient entry of natural air (401) and also prevents breakage and cramping of the air-guide structure (208) due to high velocity of natural air (401) during high speed operation of the vehicle. The curvilinear body shape of the one or more air guide structures (208) provides efficient circulation of air inside the hollow structure to further reduce the temperature of the air being let inside the one or more air guide structures (208).The front portion of the one or more air guide structures (208) with a curvilinear shape is wider providing high amount of cool air to enter the one or more air guide structures (208). Gradually, the width of the one or more air guide structures (208) decreases towards the outlet portion (406). The narrower pathway of air flow increases resistance in the path of air and thereby at the outlet portion (406), air gushes out at as a jet at a higher velocity providing faster cooling to the battery (300).
[058] The outlet portion (406) further has an extended longitudinal opening (408) which enables the flow of cool air (420) inside the battery covering unit (202) to cool the battery (300). The narrow structure of the outlet portion (406) gushes out the natural cool air (420) at a high velocity and thereby creates a jet of cooled air over the hot battery (300) and in turn rapidly cools the battery (300). The inlet portion (400) has a wedged shape which is designed such that more air can enter the inlet portion (400) without increasing the size of the inlet portion (400). The inlet portion (400) further comprises a plurality of ridges (402). The plurality of ridges (402) are present on the top region of the inlet portion (400) to ensure optimum strength to the elongated region of the air-guide structure (208). A flow path (418) of the natural air (401) inside the hollow one or more air guide structures (208) provides gradual reduction in the width of the elongated tube-like structure and thereby leads to increased pressure of letting out the cooled air as a jet (420) through the extended longitudinal opening (408) of the outlet portion (406).
[059] The elongated tube-like structure of the air-guide structure (208) is of considerable length and extend to have a curvilinear body shape (404). The length of the air-guide structure (208) ensures that minimum foreign particles can travel to the top region of the battery (300) and thus the battery (300) is also protected from foreign particles. Further, the elongated tube-like structure of the air-guide structure (208) is assembled with the fuel tank assembly (200) to obviate the gap conventionally present in between the fuel tank assembly (200) and the body panels which traditionally led to entry of dirt particles through the gaps and also damaged the plastic parts during running condition of the vehicle. Therefore, the present subject matter also ensures smooth fit and finish without any gap between the parts and thereby provides an aesthetic appeal. In an alternate embodiment, the elongated tube structure of the air-guide structure (208) is a part of the body panels (204) as well. The one or more air guide structures (208) comprises a plurality of primary mounting points (410, 412) which aids in mounting of the one or more air guide structures (208) below the fuel tank assembly (200). Furthermore, the elongated tube-like structure of the air-guide structure (208) is a hollow tube structure to allow the passage of cool air towards the outlet portion (406) to cool the battery (300). The air-guide structure (208) is separated into a first part (416) and a second part (414). By dividing the one or more air guide structures (208) into two parts, easy assembly of the one or more air guide structures (208) is achieved. Further, due to the curvilinear shape of the one or more air guide structures (208), it is cheaper to design two separate parts and connect them together using a connecting means rather than a single part, because the manufacturing of a single huge part requires multiple processes, which is time consuming.
[060] Further, during assembly of the one or more air guide structures (208) on the vehicle, if any damage occurs to the single part, the entire one or more air guide structures (208) has to be discarded and also mounting of a single part onto the assembly line will take more time. The first part (416) being configured to have the wedge like profile for entry of cool air. The first part (416) comprising said plurality of primary mounting points (410, 412) in a front and rear portion respectively of said first part (416) for mounting said one or more air guide structures (208) below said fuel tank assembly (200). The first part (416) comprising a plurality of secondary mounting points (422, 430, 432) in a middle portion of said first part (416) for connecting said first part (416) with said second part (414). The second part (414) comprising said extending longitudinal opening (408) in rear portion of said second part (414). The second part (414) comprising a plurality of tertiary mounting points (424, 434) in a middle portion of said second part (414) for connecting said first part (416) with said second part (414).
[061] . The direction of the air flow is shown by means of arrows (418) from the inlet portion (400) to the outlet portion (406). The air-guide structure (208) is further mounted through plurality of primary mounting points (410, 412) below the fuel tank assembly (200).
[062] Figure 5 illustrates a perspective view of the air-guide structure being mounted under a fuel tank assembly depicting the direction of flow of cool air, in accordance with an embodiment of the present subject matter. The one or more air guide structures (208) is configured to be mounted on both left side and right side of the vehicle. The one or more air guide structures (208) being configured to be mounted under the fuel tank assembly (200) enabling the one or more air guide structures (208) to not be visible to the rider when viewed from the front portion of the vehicle. Furthermore, mounting of said air guide (208) under the fuel tank assembly (200) on both left and right side of the vehicle, provides influx of jet of cool air from both left and right side of the vehicle on the battery (300). This provides efficient air circulation inside the battery covering unit and maintains an ambient temperature on the body panels of the vehicle. A secondary mounting point (500) enables a snap fit mechanism to attach said one or more air guide structures (208) with the fuel tank assembly (200). In another embodiment, the secondary mounting point (500) is used to mount the one or more air guide structures (208) with the fuel tank assembly (200) through screws.
[063] In one embodiment, the one or more air guide structures (208) is provided on both left side and right side of the vehicle. Thus, the high gushing of jet like cool air being forced onto the battery (300) from both the left side and the right side at a tapering manner leads to overall cooling of the battery (300) from all the sides. Further, heat from the battery is not captured inside the body panels (204) and is expelled rapidly through the rear portion of the vehicle due to high speed gushing of cool air through the one or more air guide structures (208).
[064] In another embodiment, the one or more air guide structures (208) is provided in either the left side or the right side of the vehicle. This arrangement provides localized cooling of the battery (300) and also provides unidirectional flow of natural air for efficient cooling of the battery (300).
[065] While the present invention has been shown and described with reference to the foregoing preferred embodiments, it will be apparent to those skilled in the art that changes in form, connection, and detail may be made therein without departing from the spirit and scope of the invention.
