Description

[0001] VEHICLE

[0002] FIELD OF THE INVENTION

[0003]

[0001] The present invention relates to a vehicle comprising a skid plate positioned below a battery of the vehicle.

[0004] BACKGROUND OF THE INVENTION

[0005]

[0002] It is traditional to provide a battery that provides power to a motor unit carried by the vehicle. The motor unit generates motive power on the basis of the power received from the battery and supply the same to one or both of a front ground engaging member and a rear ground engaging member of the vehicle.

[0006]

[0003] To protect the battery and the motor unit from stones and mud from a bottom side of the vehicle, it is desired to provide a skid plate made of plastic on a bottom side of the battery and the motor unit. However, it has been observed that the skid plate made of plastic which is positioned on the bottom side of the battery and the motor unit does not have sufficient strength.

[0007]

[0004] While traditionally, a vehicle is lifted by using a jack which comes in contact with the frame structure, when a skid plate is located on the bottom side of the battery and the motor unit, it becomes difficult to place the jack such that it comes in contact with the frame structure. Instead, the jack comes in contact with the skid plate and during a lifting action, all stress gets applied on to the skid plate. Since the skid plate made of plastic does not have sufficient strength, lifting the vehicle using a jack which is positioned below the skid plate results in breakage of the skid plate.

[0008]

[0005] Apart from being designed to have high strength, the skid plate must also establish air flow which cools the battery and the motor unit. It has however, been observed that the traditional skid plate placed below the battery and the motor unit hinders in flow of the air which is needed for cooling of the battery and the motor unit. Additionally, or alternatively, the traditional skid plate placed below the battery and the motor unit does not establish air flow specifically directed towards the heat generating portions of the battery and the motor unit.

[0009]

[0006] In most instances, the skid plate is attached to a frame structure, which supports the battery and the motor unit. In particular, the skid plate has a first front attachment provision, a second front attachment provision, a first rear attachment provision, and a second rear attachment provision through which the skid plate is attached to the frame structure. However, depending upon the structure of the frame structure or if the size of the battery is large, the frame structure may only comprise a first counter attachment provision for attaching to the first rear attachment provision and a second counter attachment provision for attaching to the secondrear attachment provision. In such a case, very less space is available to attach the skid plate to the frame structure and it becomes difficult to attach the skid plate to the vehicle. In most cases, the battery located upon the skid plate is designed to have gas venting holes (which vent out gases formed within the battery) on the side walls of the battery. Placement of the gas venting holes on the side walls of the battery may harm user legs in case of gas venting. One of the reasons for placement of the of the gas venting holes on the side walls of the battery is that the skid plate does not establish air flow along an underside of the battery. Thus, there exists at least one drawback in the existing art that needs to be addressed.
