Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motorcycle assembly technology, specifically relating to an assembly structure of a rear wheel mudguard and a frame. Background Technology
[0002] For motorized two-wheeled vehicles like motorcycles, mudguards are installed on the wheels to protect the wheels and frame, and to prevent mud and debris from being kicked up by the wheels and contaminating the rider and the vehicle. The rear mudguard is a crucial component of a motorcycle. Installed at the rear of the frame, above the rear wheel, its primary function is to shield the vehicle from mud and water splashed up by the rear wheel during driving, preventing it from splashing onto internal components or the rider.
[0003] However, for most models, the rear fender of a motorcycle is directly assembled with the rear fork. This traditional rear fender assembly has the following drawbacks: the "two-point" structure makes the assembly structure unstable, stress concentration at the assembly connection is prone to breakage, and additional support components are needed to achieve a "triangular" stable structure, which increases manufacturing costs; and during long-term vehicle operation, the rear fender will produce vibration and abnormal noise, affecting the riding experience. Utility Model Content
[0004] The purpose of this utility model is to provide an assembly structure for the rear wheel mudguard and the vehicle frame, so as to solve the problems mentioned in the background art.
[0005] The objective of this utility model can be achieved using the following technical solutions: An assembly structure for a rear wheel mudguard and a bicycle frame includes a rear fork; the front top surface of the rear fork is provided with a rear wheel mudguard that is fitted therewith, and a rear wheel mudguard support is provided on one side of the rear wheel mudguard; the rear fork is provided with a mounting plate for mounting the rear wheel mudguard and the rear wheel mudguard support thereon; the mounting plate is symmetrically arranged at the top end of the rear fork and has evenly distributed mounting holes C.
[0006] The rear wheel mudguard is an integrally formed arc-shaped structural plate, and an installation groove for installing the rear wheel mudguard support is provided on the arc panel, and an installation seat is provided at the bottom of the plate; the installation seat is provided with evenly distributed installation holes D.
[0007] The mounting groove on the rear wheel mudguard is provided with evenly distributed mounting holes A.
[0008] The rear wheel mudguard support is an integrally formed L-shaped arc plate structure. Its short bending part is fastened to the mounting groove, and evenly distributed mounting holes F are provided on the concave surface of its short bending part. The mounting holes F correspond to the mounting holes A, and the rear wheel mudguard support is installed on the rear wheel mudguard plate by bolts A.
[0009] The rear wheel mudguard support has evenly distributed mounting holes B at its longitudinal end; the mounting holes B correspond to the mounting holes C on the mounting plate and are connected to each other by bolts B.
[0010] The front top surface of the rear fork of the frame is provided with evenly distributed mounting holes E; the mounting holes E correspond to the mounting holes D on the mounting seat on the rear wheel mudguard and are connected to each other by bolts C.
[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model has a novel structure and reasonable layout. By connecting the rear wheel mudguard support to the rear fork of the frame, the relative position and gap between the rear wheel mudguard and the rear wheel can be kept constant, effectively aligning and avoiding skewing and offset. At the same time, all components are connected by bolts, which can be easily disassembled and repaired, ensuring the stability of the rear mudguard and reducing manufacturing costs.

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0016] like Figure 1-2As shown, an assembly structure of a rear wheel mudguard and a frame includes a rear fork 3; a rear wheel mudguard 1 is provided on the top front surface of the rear fork 3, and a rear wheel mudguard support 2 is provided on one side of the rear wheel mudguard 1; the rear fork 3 is provided with a mounting plate 13 for mounting the rear wheel mudguard 1 and the rear wheel mudguard support 2 thereon; the mounting plate 13 is symmetrically arranged at the top end of the rear fork 3, and has evenly distributed mounting holes C8; the rear wheel mudguard 1 is an integrally formed arc-shaped structural plate, and has a mounting groove 14 for mounting the rear wheel mudguard support 2 on the arc plate, and a mounting seat 15 is provided at its bottom; the mounting seat 15 has evenly distributed mounting holes D10; the mounting groove 14 on the rear wheel mudguard 1 has evenly distributed mounting holes A5.
[0017] The rear wheel mudguard support 2 is an integrally formed L-shaped arc plate structure. Its short-bend portion is fastened to the mounting groove 14, and evenly distributed mounting holes F12 are provided on the concave surface of its short-bend portion. The mounting holes F12 correspond to the mounting holes A5, and are installed on the rear wheel mudguard 1 by bolts A4. Evenly distributed mounting holes B7 are provided at the end of the long portion of the rear wheel mudguard support 2. The mounting holes B7 correspond to the mounting holes C8 on the mounting plate 13, and are connected to each other by bolts B6. When the motorcycle is moving, the main body of the rear wheel mudguard support 2 is connected to the rear fork 3 of the frame, and can move together with the rear wheel axle and the rear wheel, keeping the relative position and gap between the rear wheel mudguard 1 and the rear wheel constant, effectively centering, avoiding skew and offset, and reducing vibration and abnormal noise from the rear mudguard.
[0018] The front top surface of the rear fork 3 of the frame is provided with evenly distributed mounting holes E11; the mounting holes E11 correspond to the mounting holes D10 on the mounting seat 15 on the rear wheel mudguard 1, and are connected to each other by bolts C9; the rear wheel mudguard 1, the rear wheel mudguard support 2 and the rear fork 3 of the frame are connected to each other by bolts, and the mudguard can be disassembled and replaced by simply removing these bolts, which facilitates disassembly, assembly and maintenance, ensures the stability of the rear mudguard and reduces manufacturing costs.
[0019] In use, this utility model integrates the rear wheel mudguard 1 and the rear wheel mudguard support 2 onto the rear fork 3 of the frame and uses a threaded connection. This connection method ensures the assembly of the rear mudguard and facilitates disassembly and replacement, thereby improving product production efficiency.
