DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0020] like Figure 1 and Figure 2As shown, a curved beam type motorcycle frame includes a front end and a main frame, the front end is a frame top connection structure; the front end 1 is connected to the main frame 11 at the bottom, the main frame 11 is a cradle-type installation structure, the rear end of the main frame 11 extends between the tail frame 6 and the buffer assembly 4, and the rear end of the main frame 11 is fixedly connected to the support plate 13 at the bottom of the buffer assembly 4, the buffer assembly 4 is respectively connected to the combination frame 3 and the tail frame 6 at the front and rear, and the combination frame 3 is connected to the front end 1 through the neck frame 2. Among them, the main frame 11 is used as the main structure of the frame body, and through its own bending structure, it forms a cradle frame body with the front end 1, the neck frame 2 and the combination frame 3, which is used to store components such as the motorcycle engine. The tail frame 6 is combined with the head end 1 and the neck frame 2 through the combined frame 3 to form a top frame, and the top frame structure can connect the neck frame 2, the combined frame 3 and the tail frame 6 through the buffer component 4. The segmented buffer structure can prevent the vibration force from affecting the top frame. The three groups of segmented frames cooperate with the buffer component 4 to gradually buffer the vibration force. The force is compared with that of ordinary frames, and the buffering process can be completed through segmented acceptance.

[0021] like Figure 1 and Figure 2 As shown, the buffer assembly 4 includes a spring buffer 12 and a support plate 13; the front end of the spring buffer 12 is docked with the rear end of the neck frame 2, and the rear end of the spring buffer 12 is docked with the connecting key 15; wherein, the spring buffer 12 can complete the vibration force between the neck frame 2 and the combination frame 3 through its own buffer structure.

[0022] The support plate 13 is horizontally installed on the inner side of the neck frame 2 and the inner side of the assembly frame 3. The support plate 13 is a structure of multi-faceted contact and lifting installation in the horizontal direction.

[0023] like Figure 1 and Figure 2 As shown, the connecting key 15 is installed in the installation gap at the rear of the assembly frame 3, and the rear end of the connecting key 15 is installed and docked with the tail frame 6. Among them, the connecting key 15 serves as a support for the spring buffer 12, and the connecting key 15 can be used as a connecting structure between the tail frame 6 and the assembly frame 3 from front to back.

[0024] like Figure 1 and Figure 2 As shown, the support plate 13 is in a lifting state along the bottom of the assembly frame 3, the bottom middle section of the support plate 13 is fixedly connected to the tail end of the main frame 11, and the top of the support plate 13 is fixedly connected to the assembly frame 3 through bolts. The support plate 13 completes the extended support process at the assembly frame 3 and the tail end of the main frame 11 where the human body is subjected to more force.
