DESC:TECHNICAL FIELD
[0001] The present subject matter generally relates to a vehicle, particularly in the design and configuration of the frame assembly and the arrangement of components on a two-wheeled vehicle.
BACKGROUND
[0002] In the field of automobile technology, electric vehicles have seen remarkable advancements in recent years, with emphasis on improving efficiency, performance, and overall user experience. As the demand for sustainable transportation solutions continues to rise, innovators are faced with the challenge of designing vehicles that not only meet environmental standards but also deliver practicality, reliability, and user convenience. One critical aspect of designing electrical vehicle is the configuration and integration of essential components within the vehicle's frame. Several technical challenges have been identified in the design and assembly of vehicle, prompting the development of inventive solutions to enhance their overall performance and functionality. Among these challenges, the following key issues have become focal points for innovation in the field. First, optimal space utilization. The limited space within the frame of the electric vehicle demands careful consideration for the placement of critical components such as the electric motor, on-board charger, motor control unit, and secondary battery. Efficient utilization of this space is essential to accommodate these components without compromising performance or rider comfort. Second, weight distribution and balance. Achieving an optimal weight distribution is crucial, especially to a two-wheeled vehicle to ensure stability, handling, and overall driving dynamics. Uneven weight distribution can lead to performance issues and impact the vehicle's efficiency. Addressing this challenge requires innovative solutions in component placement and integration. Third, functional integration. As vehicle become more complex with the integration of various systems, achieving seamless functionality among different components is paramount. The need to harmonize the operation of the electric motor, charging system, and control units poses a technical challenge that demands innovative design solutions. Fourth, rider comfort and accessibility. Vehicles must be designed with the rider in mind, ensuring a comfortable and ergonomic experience. Placing components in positions that enhance rider accessibility and comfort, requires innovative design approaches. Fifth, structural integrity and support. The structural design of vehicle is crucial for safety and overall durability. Providing adequate support for critical components, such as the rear suspension and seat, is a challenge that necessitates inventive solutions to enhance the overall structural integrity of the vehicle.
[0003] In conventional systems, component placement is very crucial, an approach involves placing components with a systematic design. But many a times placement of components often results in suboptimal use of space and inefficient weight distribution. It may lead to challenges in system integration, maintenance, and overall vehicle performance. For example, usually an electric motor is mounted on a hub of the vehicle. But when the need comes to increase torque and capacity of the electric motor, mounting of the motor on the hub of the wheel is not possible due to increase in weight and size of the electric motor. Then there is a need to place the electric motor at a new optimal location for the proper functioning of the two-wheeled vehicle.
[0004] In conventional systems, fixed component locations assign fixed locations for components, this method might not be ideal for flexible configurations and designs. This method can limit flexibility in design and may not account for variations in component sizes and shapes.
[0005] In conventional systems, a trial-and-error approach is done to identify optimum component placement, adjusting positions based on performance testing. This method can be time-consuming, costly, and may not result in an optimal solution for all aspects of vehicle design.
[0006] In conventional systems, achieving proper weight distribution often involves manual adjustments during the manufacturing process. This approach may lack precision and could lead to inconsistencies, impacting the vehicle's balance and handling.
[0007] In conventional systems, standardized structural elements as used for support which, may not be tailored to the specific needs of each component. This can result in over-engineering or underperformance, affecting both the structural integrity and overall weight of the two-wheeled vehicle.
[0008] Conventional systems lack modularity, making it challenging to adapt to evolving technologies or incorporate new features. This can result in vehicles that become quickly outdated in terms of technology and user preferences.
[0009] In many other conventional designs, power source is placed in between the frame and the motor is placed below the power source which affects the ground clearance of the two-wheeled vehicle. Even if the ground clearance is maintained by increasing the height of the two-wheeled vehicle, then it may lead to a problem related to riding comfort and seat height.
[00010] The shortcomings of these conventional systems highlight the need for more innovative and integrated approaches to component placement and design in vehicle. In already known arts, the swingarm is mounted on both the sides of the wheel of the two-wheeled vehicle where the motor is mounted in between the swingarm. This leads a problem of accessibility, assembly and disassembly and serviceability.
[00011] Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of described systems with some aspects of the present invention, as set forth in the remainder of the present application and with reference to the drawings.
