THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED.

FIELD OF THE INVENTION:
[001] The present invention relates to a frame structure of a vehicle.

BACKGROUND OF THE INVENTION:
[002] Referring to Figure 1, there is illustrated a side view of a conventional vehicle which includes a conventional frame structure. Referring to Figure 2, the conventional frame structure comprises a head pipe for steerably supporting a steering mechanism; a main pipe extending downwardly and rearwardly from the head pipe toward the rear of the vehicle; a first lower frame joined to a lower part of the main pipe and extending toward the rear of the vehicle; a second lower frame joined to a lower part of the main pipe and extending toward the rear of the vehicle; a first rear frame joined to the first lower frame and extending toward the rear of the vehicle; and a second rear frame joined to the second lower frame and extending toward the rear of the vehicle. It has been found that during driving conditions, the steering mechanism experiences vibrations. While the frame structure is expected to dampen the vibrations, it has been observed that the conventional frame structure does not sufficiently dampen the vibrations. Also, it has been observed that since the vibrations are transmitted to the conventional frame structure, the first lower frame and the second lower frame are required to be strengthened by providing additional support elements. Providing the additional supporting elements increases weight of the frame structure and an overall weight of the vehicle, increases cost of the frame structure vehicle and an overall cost of the vehicle, and a complexity of the frame structure and overall complexity of the vehicle. Additionally, the frame structure being a substantially visible part, it can also adversely impact the aesthetic appeal of the vehicle. Therefore, there exists a need to address one or more of the aforesaid disadvantages.

These sections are essential for the overall structure and provide support and strength to the frame.

[0089] The first lower frame (106) is comprised of three main parts: a front end part (126), a rear end part (128), and a middle part (130). These sections are responsible for providing support and stability to the front portion of the frame structure. Similarly, the second lower frame (108) also consists of a front end part (132), a rear end part (134), and a middle part (136). These components contribute to the support and stability of the frame's second lower section.

[0090] Moving on to the upper frames, the first upper frame (114) includes a front end part (150) and a rear end part (152). The front end part (150) of the first upper frame is attached in a releasable manner to the first upper part (122) of the main pipe (104), while the rear end part (152) of the first upper frame is releasably attached to the front end part (138) of the first rear frame (110).
