Description

Technical Field

[0001] The utility model relates to a vehicle frame, in particular to a lightweight four-wheel vehicle frame. Background Art

[0002] In the traditional four-wheel vehicle frame design, a large number of mounting plates are usually used on the frame to install various functional parts. This design method results in a larger frame volume, increases the overall weight of the vehicle, and is not conducive to the lightweight development of the vehicle. In addition, the lack of effective reinforcements in the traditional frame design makes the overall strength of the frame low and difficult to withstand various stresses and loads during long-term use. This unreasonable structural design makes the frame prone to deformation and damage during use, affecting the service life and safety of the vehicle.

[0003] In particular, large pedal tubes are usually provided on both sides of the frame. This design further increases the size of the frame and reduces the flexibility and aesthetics of the vehicle. The presence of the pedal tubes not only takes up extra space, but also makes the overall design of the frame more complicated, increasing the difficulty of manufacturing and maintenance.

[0004] Therefore, how to achieve lightweight design of the frame and simplify the structure of the frame while maintaining the frame strength has become an important issue in the current technical field. A new frame design method is needed that can effectively reduce the volume and weight of the frame while improving the overall strength and stability of the frame to meet the requirements of modern four-wheeled vehicles for lightweight and high strength.
