[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0020] In the description of this utility model, it should be noted that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, or the orientation or positional relationship commonly understood by those skilled in the art. These terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used to distinguish the description and should not be construed as indicating or implying relative importance.

[0021] Example: like Figure 1-4As shown, this embodiment proposes a lightweight motorcycle frame, including two parallel bottom brackets 1. Two lower support columns 2 are fixedly welded between the two bottom brackets 1. A side fixing bracket 3 is fixedly welded to one end of each bottom bracket 1. A mounting plate 4 is welded to the end of each bottom bracket 1 away from the side fixing bracket 3. An upper support column 5 is fixedly welded between the upper surface of the mounting plate 4 and the two side fixing brackets 3. A rectangular groove 6 is formed on the outer surface of the bottom bracket 1. By forming a rectangular groove 6 on the bottom bracket 1, the amount of material used in the bottom bracket 1 is reduced, effectively reducing the weight. Several trapezoidal reinforcing blocks 7 arranged linearly are fixedly welded to the inner surface of the rectangular groove 6. The depth of the rectangular groove 6 is equal to the cross-sectional area of ​​the circular bottom bracket 1. Half the diameter of the surface, the trapezoidal reinforcing block 7 is designed to be narrower at the top and wider at the bottom. Several trapezoidal reinforcing blocks 7 with a narrower top and wider bottom are fixedly welded inside the rectangular groove 6, which can effectively disperse stress and enhance the structural strength of the bottom support 1, avoiding excessive reduction in the strength of the bottom support 1 due to the opening of the rectangular groove 6. Several first arc-shaped openings 8 and several second arc-shaped openings 9 are opened through the outer surface of the lower support column 2. A reinforcing guard plate 10 is fixedly welded between the two side fixing frames 3. An elliptical opening 11 is opened through the reinforcing guard plate 10. A cross-shaped reinforcing plate 12 is fixedly welded to the inner surface of the elliptical opening 11. By opening multiple first arc-shaped openings 8 and second arc-shaped openings 9 on the lower support column 2, it is also to reduce materials and achieve lightweighting.

[0022] like Figure 1 and Figure 2 As shown, a first connecting column 13 is fixedly welded between one side surface of the mounting plate 4 and the outer surface of the upper support column 5. A middle support column 14 is fixedly welded between the two bottom brackets 1. The middle support column 14 is located between the lower support column 2 and the first connecting column 13. The first connecting column 13 strengthens the connection between the mounting plate 4 and the upper support column 5 and improves the connection stability. The middle support column 14 supports and reinforces the middle part of the two bottom brackets 1, enhancing the overall structural stability of the bottom brackets 1.

[0023] like Figure 4 As shown, the first arc-shaped opening 8 and the second arc-shaped opening 9 have the same specifications. Several first arc-shaped openings 8 and several second arc-shaped openings 9 are arranged in an alternating manner. The alternating arrangement of the first arc-shaped openings 8 and the second arc-shaped openings 9 makes the force on the lower support column 2 more uniform and avoids stress concentration due to the opening of local arc-shaped openings, thus ensuring the support performance of the lower support column 2.

[0024] like Figure 1 and Figure 2As shown, the thickness of the cross-shaped reinforcing plate 12 is less than that of the reinforcing guard plate 10. The reinforcing guard plate 10 is located between the bottom bracket 1 and the upper support column 5. By providing an elliptical opening 11 through the reinforcing guard plate 10, the material of the reinforcing guard plate 10 is reduced. By welding the cross-shaped reinforcing plate 12 inside the elliptical opening 11, the reinforcing guard plate 10 can be reinforced from multiple directions, thereby improving the strength of the reinforcing guard plate 10 and enabling it to better connect to the side fixing frame 3, thus ensuring the overall stability of the frame.

[0025] like Figure 1 As shown, the upper support column 5 is inclined, which can more reasonably transmit and disperse the force from the direction of the mounting plate 4. In conjunction with the first connecting column 13, the middle support column 14 and other components, it forms a stable and strong frame structure. While achieving overall lightweighting, it ensures that the frame can withstand various loads during the operation of the motorcycle.

[0026] The working principle of the above embodiment is as follows: By opening a rectangular groove 6 on the bottom support 1, the amount of material used in the bottom support 1 is reduced, effectively reducing the weight. At the same time, several trapezoidal reinforcing blocks 7, which are narrower at the top and wider at the bottom, are fixedly welded inside the rectangular groove 6, which can effectively disperse stress and enhance the structural strength of the bottom support 1, avoiding excessive reduction in the strength of the bottom support 1 due to the opening of the rectangular groove 6. By opening multiple first arc-shaped openings 8 and second arc-shaped openings 9 on the lower support column 2, the same purpose is to reduce material and achieve lightweighting. The staggered arrangement of the first arc-shaped openings 8 and second arc-shaped openings 9 makes the stress on the lower support column 2 more uniform, and will not cause stress concentration due to the opening of local arc-shaped openings, thus ensuring the support performance of the lower support column 2. By opening an elliptical opening 11 through the reinforcing guard plate 10, the material of the reinforcing guard plate 10 is reduced. By welding a cross-shaped reinforcing plate 12 inside the elliptical opening 11, the reinforcing guard plate 10 can be reinforced from multiple directions, improving the strength of the reinforcing guard plate 10, so that it can better connect to the side fixing frame 3, and ensuring the overall stability of the frame.

[0027] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
