Description

Technical Field

[0001] The present application relates to the field of body structures of two-wheeled straddled motorcycles, and in particular to a motorcycle. Background Art

[0002] Currently known two-wheeled straddled motorcycles can be roughly divided into three types and five variations based on the body posture. The first type is the cruising state, including two forms of high posture and low posture. The characteristics are that the body posture is high in the front, low in the rear, low in the center of gravity, small ground clearance, poor passability, low in the riding posture, and the foot control position is forward. The high posture hand control position is high, and the trunk is vertical. The low posture hand control position is low and the trunk is leaning forward. The second type is the off-road form, which is characterized by a body posture with a high front, high in the rear, high in the center of gravity, large ground clearance, strong passability, and a riding posture with a high sitting point, high in the hand control position, vertical in the trunk, and a drooping foot control position. The third type is the street running state, including two forms of high posture and low posture. The characteristics are that the body posture is low in the front, high in the rear, low in the center of gravity, small ground clearance, poor passability, high in the riding posture, high in the hand control position, the trunk is leaning forward, and the foot control position is drooping, and the low posture hand control position is low, the trunk is lying forward, and the foot control position is backward. The three types provide different driving experience and passing performance.

[0003] The currently known two-wheeled motorcycles are only limited to the body posture rear shock absorber extension and retraction to cause the rear end of the vehicle to rise and fall, and the extension and retraction range is small, the degree of change is limited, and the height of the front of the vehicle is fixed. In addition, the riding posture, sitting point, hand control, foot control height and related angle changes are not involved at all. These reasons cause the current motorcycle body posture to change less, and the conversion between two states cannot be fully in place, let alone the mutual conversion between three states. Therefore, on any motorcycle currently known at home and abroad, it is impossible to have three different body postures and riding postures at the same time, it is impossible to create different riding feelings and passing performances, and it is impossible to achieve true cross-border. The change of the body posture causes the change of the center of gravity of the driver and passenger's torso, while the foot control and hand control cannot change accordingly to produce the corresponding riding posture, which not only poses a safety hazard but also affects the comfort.

Rotate the handlebars downward, lower the position of the hand control assembly, move the front footrest backward to the rear position of the frame, rotate the seat bracket downward, and keep the seat parallel to the ground, thus forming a low-posture street-style riding posture with the torso leaning forward, a high sitting point, feet pedaling back, and hand control positions lowered, such as the current track supercar motorcycles.

[0068] The principles of the technical solution embodiment provided in this application are divided into two parts:

[0069] The first part is to adjust the body posture. First, the height of the front position of the vehicle can be changed by synchronously extending and retracting the two front shock absorbers. Second, the height of the rear position can be changed by extending and retracting the rear shock absorber. Thus, three different body postures can be achieved from the front to the rear: high in front and low in the rear, high in front and high in the rear, and low in front and high in the rear. Third, a fairing is set at the lower part of the vehicle body, with three front and rear assembly holes reserved. The front hole is connected to the frame, and a rear assembly hole is selected to fasten the frame according to different body postures to achieve the change of the angle between the fairing and the frame, so that the fairing does not change with the angle of the frame, always remains parallel to the ground, tidies the airflow of the belly of the vehicle body, and achieves a coordinated appearance of the vehicle body.

[0070] The second part is to adjust the riding posture. Change the current single position and fixed angle assembly of the motorcycle body components, increase the telescopic, rotational and displacement functions of the corresponding body components, and realize the corresponding changes in the angles of the driver's seat, hand control and foot control positions corresponding to different body postures, forming a more comfortable and more favorable riding posture. First, the seat bracket is preset with multiple assembly holes, and any two holes are connected to the frame to realize the change of the angle between the seat bracket and the frame, so that one end of the seat is fixed and the other end is raised or drooped at a certain angle, so as to realize the height change of the sitting position. Second, the handlebar is rotated to the rising or drooping angle respectively with the preset assembly hole on the moon plate of the former shock absorber as the axis, and then the hand control assembly is rotated to the horizontal angle and tightened with the tube core at both ends of the handlebar as the axis to realize the height change of the hand control position. Third, three pairs of angled assembly holes are reserved symmetrically from front to back on both sides of the frame, and the foot control assembly is assembled with the front foot pedal at a corresponding angle. The shift lever and the brake lever are connected to the rear with a steel wire hose to realize the change of the front foot position and the foot control pedal angle. Fourth, the rear pedal is rotated with the rear pedal assembly hole as the axis, and an upward or downward angle is selected for tightening, so as to achieve the height change of the rear pedal position.

[0071] Preferred embodiments and descriptions of the technical principles used. At the same time, the scope of the invention involved in this application is not limited to the technical solutions formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in this application.
