Description

Technical Field

[0001] The present invention belongs to the technical field of motorcycle assembly, and particularly relates to an integrated assembly structure of a rear mudguard and a frame. Background Art

[0002] The motorcycle rear mudguard is one of the important components of a motorcycle. The motorcycle rear mudguard is installed at the rear of the frame and above the rear wheel. Its main function is to block the mud and water splashed by the rear wheel when the vehicle is running, preventing the mud and water from splashing onto the internal components of the vehicle or the rider. However, for most motorcycle models, after the rear mudguard is assembled with taillights and turn signals, it is directly assembled on the frame support. The traditional rear mudguard assembly has the following defects: Usually, the rear mudguard adopts a split structure, which leads to cumbersome installation procedures. To ensure the assembly of the rear mudguard, multiple frame supports need to be welded, which affects the stability of the rear mudguard. At the same time, stress concentration at the welding parts is prone to cause fractures, and additional fasteners need to be welded, increasing the manufacturing cost. In addition, it is difficult to replace the taillights, turn signals, rear license plate lights, rear reflectors, etc. installed on it. Summary of the Invention
