[0028] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0029] This embodiment mainly describes a structure of a motorcycle frame with a vibration reduction effect, as follows:

[0030] like Figure 1-Figure 8As shown, a motorcycle frame with a vibration reduction effect comprises a front frame 1, an upper beam frame 2, a lower beam frame 3 and a rear beam frame 4, and a support rod 6 connected to the upper beam frame 2 and the lower beam frame 3, wherein the front frame 1 is connected to the upper beam frame 2 and the lower beam frame 3 respectively, the upper beam frame 2 is connected to the lower beam frame 3, the rear beam frame 4 is connected to the upper beam frame 2, a connecting block 13 for connecting to an engine is arranged on the support rod 6, and a plurality of connecting members 5 for connecting to the engine are arranged on the upper and lower beam frames 3, and the connecting members 5 each include The mounting plate 51 is mounted on the upper beam frame 2 and the lower beam frame 3 by bolts 12. The mounting plate 51 is C-shaped so that the mounting plate 51 can better fit with the upper beam frame 2 and the lower beam frame 3. A connecting plate 52 is respectively provided at the left and right ends of the mounting plate 51. The connecting plate 52 is provided with a connecting hole 56. The connecting hole 56 is used to connect with the engine or other parts of the motorcycle; the mounting plate 51 is provided with an abutment block 53 on one side close to the lower beam frame 3. The contact block 53 abuts against the outer wall of the lower beam 3, and the top of the abutting block 53 is connected to the mounting plate 51. When the connecting member 5 is installed on the lower beam 3, the mounting plate 51 is fastened to the lower beam 3 as the bolts 12 are tightened, and the abutting block 53 abuts against the lower beam 3. In this way, the abutting block 53 can support the mounting block, which can improve the bearing effect of the connecting member 5, thereby improving the service life of the connecting member 5. The mounting plate 51 is convenient to use through the first mounting hole 58 and the bolt 12. The connecting member 5 is disassembled and assembled with the lower beam frame 3, so that the replacement of the connecting member 5 is convenient. A slide groove 54 is provided on the inner wall of the mounting plate 51, and a slider 55 is provided to slide in the slide groove 54. The slider 55 is connected to the abutment block 53, so that the stability of the abutment block 53 on the mounting plate 51 is improved. A second mounting hole 57 is provided on the mounting plate 51, and the abutment block 53 is detachably connected to the mounting plate 51 through the second mounting hole 57, so that the connection between the abutment block 53 and the mounting plate 51 is convenient.The upper beam frame 2 and the lower beam frame 3 both include a main pipe 7, which is the main supporting part of the motorcycle frame. The main pipe 7 is provided with a sleeve 8, and a plurality of reinforcing blocks 9 are provided between the sleeve 8 and the main pipe 7, so that the strength of the upper beam frame 2 and the lower beam frame 3 can be improved, so that the service life of the motorcycle frame can be extended. A vibration-damping layer 10 is provided on the inner wall of the reinforcing block 9, and the reinforcing block 9 abuts against the outer wall of the main pipe 7. The vibration-damping layer 10 is located between the reinforcing block 9 and the outer wall of the main pipe 7. The provision of the vibration-damping layer 10 can reduce the vibration of the main pipe 7 to be transmitted to the sleeve 8, so that the vibration generated when the engine is started can be reduced and transmitted to the motorcycle body through the upper beam frame 2 and the lower beam frame 3, so that the use comfort of the motorcycle is improved. A plurality of limit blocks 11 are provided on the outer wall of the main pipe 7, and the limit blocks 11 are respectively located between the reinforcing blocks 9, so that the sleeve 8 can be prevented from rotating on the main pipe 7, thereby ensuring the stability of the sleeve 8 on the main pipe 7. ;

[0031] When the engine is working, the vibration generated by the engine is transmitted to the support rod 6 through the connecting block 13 on the support rod 6. The support rod 6 includes a rod body 61, and the connecting block 13 is installed on the rod body 61. The left and right ends of the rod body 61 are respectively provided with an installation cavity 62, and a vibration reduction sleeve 64 is respectively inserted in the installation cavity 62. The vibration reduction sleeve 64 is interference fit with the installation cavity 62, and a connecting rod 63 is respectively inserted in the vibration reduction sleeve 64. The connecting rod 63 is interference fit with the vibration reduction sleeve 64, and the connecting rod 63 is provided with a screw hole 66 at the end away from the rod body 61. In this way, the support rod 6 is connected to the bolt 12 at the connection between the upper beam frame 2 and the lower beam frame 3 through the screw hole 66 on the connecting head 65, which facilitates the disassembly and assembly of the support rod 6; in this way, when the vibration generated by the engine is transmitted through the connecting block 13 on the support rod 6 When the connecting block 13 is transmitted to the support rod 6, the rod body 61 is first subjected to vibration. Since a vibration-damping sleeve 64 is provided in the installation cavity 62, and the connecting rod 63 is inserted in the vibration-damping sleeve 64, the vibration on the rod body 61 has been weakened when it is transmitted to the connecting rod 63. In this way, the vibration is also weakened when the connecting head 65 on the connecting rod 63 transmits the vibration to the upper beam 2 and the lower beam 3. In this way, the vibration of the upper beam 2 and the lower beam 3 caused by the operation of the engine can be reduced, thereby further improving the comfort of use of the motorcycle. A buffer pad 67 is provided on the connecting rod 63 between the second connecting head 65 and the vibration-damping sleeve 64, and the two sides of the buffer pad 67 sleeve are respectively abutted against the rod body 61 and the connecting head 65. In this way, the contact between the rod body 61 and the connecting head 65 can be avoided, thereby improving the reliability of the support rod 6.
