[0001] The present subject matter described herein generally relates to a vehicle, and particularly but not exclusively relates to a cover frame assembly of a vehicle.

BACKGROUND
[0002] Conventionally, in a two-wheeled vehicle, particularly a motorcycle comprises of an engine and a battery as sources of power. The motorcycle engine is mounted to a front lower portion of a body frame of the vehicle, either mounted transversely with a crankshaft aligned perpendicular to the frame or longitudinally with the crankshaft parallel to the frame. The engine is mounted on the frame by means of an engine mounting bracket. The battery used for automotive purpose is a rechargeable battery that also supplies electrical current to the vehicle and can be mounted on a right side or a left side of the vehicle, depending upon the design and need of the vehicle.
[0003] The engine of the vehicle needs an ideal amount of electric current to generate the required power for starting and operating the vehicle. The battery fulfills the requirement of the ideal current by feeding a starter with the required electric current, which in turn starts the engine. Once the engine starts, it starts generating required power to keep the vehicle in continuous motion. The power from the engine is then transmitted to a rear wheel through a power drive mechanism, such as a drive chain. The power drive mechanism, such as the drive chain aids in driving and rotating the rear wheel of the vehicle, which induces motion in the vehicle. Post the engine starts generating its own power required for driving the vehicle, the battery of the vehicle supplies power to the vehicle’s electrical system for performing ancillary vehicular functions. The battery in turn gets charged with help of an alternator and a convertor, as per the increase or decrease in charging demand of the vehicle. In an EV or HEV type vehicle the powertrain comprises of a motor drive which is supplied required energy from one or more batteries.

DETAILED DESCRIPTION
[0001] Usually, in a vehicle, particularly a two wheeled vehicle, a high temperature is reached because of constant power generation by an engine. This high temperature r of the engine tends to further increase as a result of several factors affecting the engine. One of the major factors includes a particular riding style of a rider especially the style of throttle inputs, gear shift pattern etc. Over a time period, such particular riding style accompanied with certain other working conditions of the engine can adversely affect the performance of engine. Often, excessive heating of the engine leads to durability failure which is a result of various usage conditions like increasing and decreasing revolutions per minute of the engine while being operated without adequate coolant and oil, or operating the engine when there is a need of replacement of some essential part. Improper carburetor setting can also be one of the probable reasons of heating of the engine if the air fuel mixture is too lean (rich in air than fuel). Moreover, when engine is abused by running excessively on high revolutions per minute (rpm), with increase in engine speed, more heat is produced. Also in situations where the vehicle is in stationary position, for example, waiting at traffic stops while the engine is on or where the vehicle is not moving fast enough but the engine rpm is high, heating is promoted due to scarcity of required air flow to cool the engine. Revving engine in lower gear, using faulty clutch plate, lower oil levels or lower octane fuel can also be few of the reasons of heating of the engine.
[0002] Similarly heating of a battery in a vehicle also occurs during daily usage of the vehicle. Constant drawing of power from the battery while performing day to day functions of a vehicle, such as starting, lighting, ignition, charging and functions related to ancillary system support of a vehicle can result into heating of the battery. For a typical saddle type vehicle the battery is enclosed by body panels or side covers to protect the battery form environmental factors. Additionally, in order to provide aesthetic appearance to a vehicle, the portion in which a battery is mounted is usually covered by a side cover, because of which natural air flow is obstructed resulting into inefficient cooling of the battery and thus adversely increasing the battery temperature. Other reasons for the heating of the battery can be because of the radiated heat from the engine especially when it is disposed in close proximity with the engine. Also extreme weather conditions add up to the battery heating and eventually leading to reduced life of the battery.
[0003] Traditionally, in a scooter type saddle vehicle, the cylinder head of an engine is exposed without any cover, unlike its lower part which is covered by an engine cover. This is done in order to facilitate the natural air flow required for cooling the engine. In such vehicles, while a vehicle is being ridden by a rider, the riding position of the rider is such that the leg of the rider is in constant proximity of the heated engine. Therefore, heating of the engine causes discomfort to the rider, while riding the vehicle, because of the constant feel of the increased temperature near rider’s leg area.
[0004] Furthermore, the air heated because of the radiating heat produced by the engine tends to seep in through the gap between the side covers of the vehicle, towards the internal components present in proximity with the side cover, for example a battery. The seeped in hot air comes in contact with the internal components and in absence of any escape route or counter mechanism to cool it, causes excess heating of the internal components such as a battery. This excess heating of the internal components such as a battery adversely affects the life of the internal components, which further results in compromising with the performance and durability of the two-wheeled or three wheeled vehicle. The excess heating of the internal components also increases the need of replacement of those internal components on a frequent basis.
[0005] Therefore, there exists a need to ensure safety and comfort of the rider while his leg is in proximity of the heated region of the vehicle’s engine separated by a side cover and at the same time ensuring proper cooling of the internal components present in proximity with the side cover, for example a battery . Along with it, there is a need for a channelized natural air flow, flowing through a dedicated channel to the heated regions of the internal components to facilitate effective cooling. .
[0006] The present subject matter has been devised in view of the above circumstances as well as solving other problems of known art.

The receiving opening 301a receives the protruded portion 302a from its one side and receives an deflector cover 401 from its other side. The RH front 302 is attached to the RH rear 301 by means of heat staking method or a plurality of fasteners 601, for example, two fasteners 601, such that the receiving opening 301a receives the protruded portion 302a.The deflector cover 401 is attached to the RH rear 301, such that the deflector cover 401 is placed exactly behind the protruded portion 302a protruding out of the receiving opening 301a. The deflector cover 401 is attached to the RH rear 301 by means of heat staking method or a plurality of fasteners 601, for example, two fasteners 601. The RH tapered portion 302c acts as a protective barrier for both the rider’s leg area present in the proximity of the engine area 303 (shown in Fig. 3) and for the internal components of the vehicle disposed in proximity with the cover frame assembly 101, for example battery 403 (shown in Fig. 4). Since the tapered portion 302c extends towards the cylinder head 303 (shown in Fig. 1), it shields the heated engine area which otherwise was in close proximity of the rider’s leg area in conventional two wheeled vehicles (not shown). Moreover, as the tapered portion 302c has a tapered end or nose which is inwardly bent, as a bent portion 602, away from the cylinder head 303, it acts as a barrier for isolation of the heated air radiated from the engine 119 which otherwise directly radiates onto the rider’s leg region. Additionally, the hot air in this vicinity especially during riding of the vehicle is capable of undesirably seeping in through the inner sides of the cover frame assembly 101 towards other vehicle system in conventional two wheeled vehicles (not shown). Thus, the tapered portion 302c along with its lateral flange wall functions as not just a heat barrier to blocking for the rider but also as a deflector to avoid flow of hot air on the inner side while protecting the internal components of the vehicle disposed in proximity with the cover frame assembly 101, for example battery 403 (shown in Fig. 4). The opening on the protruded portion 302a protruding out of the receiving opening 301a receives the natural cool air from the surrounding especially in vehicle running condition, which is further deflected towards the internal components of the vehicle 100 disposed in proximity with the cover frame assembly 101, for example battery 403 (shown in Fig. 4), by means of the deflector cover 401, that functions as an air deflector. The shape of the protruded portion 302a and the shape of the deflector cover 401 both conjointly help in a directed natural air flow towards the internal components of the vehicle 100 disposed in proximity with the cover frame assembly 101 such that effective cooling of the components are achieved.
[00049] Fig. 7a illustrates direction of natural cool air A1 flow at the exterior part of the cover frame assembly 101, through a protruded portion 302a present on the RH front 302 of the cover frame assembly 101 of a two wheeled vehicle 100 in accordance with an embodiment of the present invention. The cover frame assembly 101 in the present embodiment depicts the right hand side cover 300 also called as a side cover RH 300. When the vehicle 100 is in motion, the natural cool air A1 seeps inside the side cover RH 300 through the opening on the protruded portion 302a present on the RH rear 302. The natural cool air A1 seeps in first through the said opening of the protruded portion 302a, then is received by the receiving opening 301a (shown in Fig. 6) and is further deflected in a directed manner towards the internal components of the vehicle 100 disposed in proximity with the RH rear 302 by means of the deflector cover 401 (shown in Fig. 6). As a considerable portion of the engine 119 area is exposed to the outside environment, the engine also receives the natural air A1 when the vehicle is in motion. This natural air A1 impinging the frontal & side regions of the engine, get heated because of the radiated heat from the engine 119 resulting in a hot air A2. The RH tapered portion 302c of the RH rear 302 has a tapered end or nose which is inwardly bent 602 away from the cylinder head 303. The RH tapered portion 302c, therefore acts as a barrier for the hot air A2 radiated from the engine 119 which otherwise is capable of seeping in through the inner sides of the side cover RH 300 in conventional two wheeled vehicles (not shown). Thus, the RH tapered portion 302c functions as a heat barrier by deflecting back most of the hot air A2, while protecting the internal components of the vehicle disposed in proximity with the cover frame assembly 101, for example battery 403 (shown in Fig. 4).
[00050] Fig. 7b illustrates direction of flow of natural cool air A1 towards the internal components of the vehicle disposed in proximity with the cover frame assembly 101, for example, towards a second power source 403 in accordance with an embodiment of the present invention. The second power source mentioned herein can be a battery 403. The natural cool air A1 seeps in first through the opening on protruded portion 302a (shown in Fig. 6), then is received by the receiving opening 301a (shown in Fig. 6) and is further deflected in a directed manner towards the internal components of the vehicle 100 disposed in proximity with the RH rear 302 by means of the deflector cover 401.The deflector cover 401, functions as an air deflector that deflects the natural cool air towards the internal components of the vehicle 100 disposed in proximity with the RH rear 302. The shape of the protruded portion 302a (shown in Fig. 6) and the shape of the deflector cover 401 both conjointly help in a directed natural air flow towards the internal components of the vehicle 100 disposed in proximity with the cover frame assembly 101 such that effective cooling of the components is achieved. Thus the effective channelizing of the natural cool air flow A1 helps in effective cooling of the battery 403 and adjoining parts.
