Specification

DESC:FIELD OF INVENTION
The present invention generally relates to a field of automobiles, and more particularly to a rear structure for a two-wheeled vehicle and a method of assembly thereof.
BACKGROUND
The information in this section merely provides background information related to the present invention and may not constitute prior art(s) for the present invention.
Generally, two-wheeled vehicles, such as motorized scooter, motorcycle, etc., have a body frame to support various components of the vehicle including parts necessary to meet the aesthetical and regulatory requirements. The vehicle’s rear side is generally provided with various important components such as a seat, a rear fender, a tail lamp, a blinker, and a rear handle which are also supported by the body frame of the vehicle. The seat of the vehicle is mounted on the body frame for providing a seating area to a rider and a passenger and the seat is designed to offer a comfortable ride to the rider and the passenger.
The rear fender of the vehicle is mounted at a rear portion of the body frame on a top side of a rear wheel to meet the vehicle’s aesthetic, safety, and regulatory requirements. The rear handle is mounted on a rear frame portion and configured to provide support to the pillion/passenger via grabbing by the pillion/passenger. Moreover, the rear handle is designed to meet the vehicle’s aesthetic requirements. The tail lamp is mounted on the rear side of vehicle which is illuminated to provide information regarding driver intentions related to direction, braking, and speed of the vehicle. Further, the blinkers are provided to indicate a direction in which the vehicle is intending to turn.
During assembly of the vehicle, the rear handle, the rear fender, the tail lamp, and the blinkers are mounted on the vehicle’s body frame independently having pre-defined fitment with respect to each other. These components are generally disassembled from the vehicle’s body frame during servicing of the vehicle or in case of any malfunctioning of the components.
With the increasing trends of global warming, vehicle emissions, and depleting fossil fuel resources, cleaner technologies with lower emissions need to be implemented in the transportation ecosystem. Certain types of motorcycles and motorized scooters are developed which utilize fuel in a form of compressed natural gas or hydrogen or liquefied petroleum gas etc. The fuel in such kind of the vehicles is stored in a cylindrical vessel or a container, and the gas fuel cylinder is fastened to the body frame and is generally provided under the seat of the vehicle.
One such example is available in patent application IN202121045739, in which the gas fuel cylinder is supported on the vehicle frame structure and then clamped. The said arrangement of the gas fuel cylinder is mounted on the vehicle’s frame and covered by the seat from the top. During servicing or any malfunctioning of the components, the heavy gas fuel cylinder must be removed from the arrangement. Further, the challenges faced during the removal and the mounting of the gas fuel cylinder from the two-wheeled vehicles are explained herein below.
Opting a conventional approach for removal of the gas fuel cylinder requires disassembling of all the components mounted on the rear frame potion (including seat, tail lamp, rear fender, rear handle, blinker, etc.). This is a tedious and challenging task and further requires high-skilled labor. Another drawback with the conventional approach is high turn-around time on the assembly line. Since, the current arrangement includes mounting of numerous components after assembling the gas fuel cylinder and each component must be mounted in a certain order, hence, components cannot be mounted independently without affecting each other.
The major challenges with the existing solution for the removal of the gas fuel cylinder from the rear of the vehicle is that there are numerous components that are mounted at the rear of the vehicle and hence, are prone to error while assembling and disassembling. This may also lead to improper fitment and vibrations in the vehicle.
Therefore, there is an urgent need for an arrangement at the rear of the two-wheeled vehicle that addresses the aforementioned challenges by providing a simple, efficient, and easy solution for servicing or maintenance tasks of the vehicle, such as removal and reinstallation of the gas fuel cylinder removal. Additionally, this arrangement can help reduce turnaround time on the assembly line.
OBJECT OF THE INVENTION
An object of the present invention is to ameliorate limitations of the existing prior art by providing a rear-structure of a two-wheeled vehicle and a method of assembly thereof.
Another object of the present invention is to provide a rear structure of the two-wheeled vehicle having a sub-frame assembly of plurality of components for easy & quick installation, assembly, and disassembly.
Yet another object of the present invention is to provide a sub-frame assembly, that is simple and facilitates quick removal and installation of a gas fuel cylinder from a rear side of the two-wheeled vehicles.
Yet another object of the present invention is to provide a simplified system and method of mounting a sub-frame assembly on a vehicle’s sub-frame.
Yet another object of the present invention is to reduce a turn-around time during vehicle’s assembly and servicing.
Yet another object of the present invention is to provide a sub-frame assembly system which is easy to disassemble and assemble using non-skilled labor.
