BACKGROUND

Technical Field

[0002] The embodiments herein are generally related to electric vehicles. The embodiments herein are particularly related to two wheeled electric vehicles. The embodiments herein are more particularly related to a system and method for securing, locking and safeguarding a battery pack in two wheeled electric vehicles. The embodiments herein are especially related to a two wheeled electric vehicles with an antiskid battery pack and locking mechanism for battery pack.

Description of the Related Art

[0003] With the advent of technology, diversified vehicles are designed for the convenience of the users. One such invention includes fuel powered electric motor vehicles. With an increased use of fuel powered vehicles, environment pollution is also increased along with an increase in greenhouse effect due to effluent gases released from the vehicles. Therefore, a preferred mode of transport is shifted from the use of fuel powered motor cycles to the use of mechanical bicycles. However, the use of mechanical bicycles for the purposes of commuting as well as a hobby requires the riders to expend a lot of energy while riding the bicycle. Further, riding the bicycle in an uphill mode requires more energy for a rider than that required for riding on flat surfaces and downhill. Furthermore, the energy expended by the user in cycling is more, when the distance covered by rider with the bicycles is more.

[0004] Mechanical Bicycles are slowly replaced with Electric bicycles thereby reducing an energy consumption of the users. The electric bicycles otherwise termed as e-bikes are more effective and efficient and yet an eco- friendly alternative to manual bicycles. The electric bicycles require considerably lesser efforts on the part of the user while riding, and provide the user with an eco-friendly option for stress-free commuting.

[0005] Electric bicycles are typically driven by a motor which is in turn powered by a battery, and therefore battery packs are used as a primary source of energy for supplying power to the motor driving the electric bicycles. Further, electric bikes contain all the features that are also provided in the mechanical bicycles.

[0006] Further the battery pack provided in a two wheeled electric vehicles is susceptible for theft and short circuit due to unwanted and unnecessary movement battery or pack inside a battery compartment during a riding process. Still further a plurality of locks are needed to lock the battery door in a battery compartment/housing and to hold the battery in a position inside the battery compartment/housing. Yet the battery has to be ejected during the replacement of the battery. The currently available solutions provides a plurality of locks and keys for achieving the abovementioned tasks thereby providing a complexity of solutions while designing the two wheeled electric vehicles.

[0007] Hence, there is a need to develop a two-wheeled electric vehicle that supports a manual mode, a power assisted mode and an exercise mode operation. Further, there is a need to develop a two-wheeled electric vehicle with an integrated secure battery box mounted on a frame of the electric vehicle. Yet there is a need to develop a two wheeled electric vehicle with an integrated locking assembly for safeguarding and arresting movement of battery pack in a battery pack assembly. Yet further there is a need to develop a two-wheeled electric vehicle with a single integrated locking assembly for locking door of battery compartment that enables ejection of battery easily. Yet further there is a need to develop a two-wheeled electric vehicle with an antiskid battery pack and single integrated battery pack lock mechanism.

[0008] The above-mentioned shortcomings, disadvantages and problems are addressed herein and which will be understood by reading and studying the following specification.
