[0035] Retro motorcycles, with their unique blend of classic and modern design, have attracted the attention of many motorcycle enthusiasts and collectors in recent years. However, existing retro motorcycle front fork structures have many shortcomings, especially poor shock absorption and bulky structures, which seriously affect riding comfort and stability, and also hinder the lightweight design and performance improvement of retro motorcycles.

[0036] To resolve these issues, please refer to Figures 1-5 This invention proposes a retro motorcycle front fork structure, including a bracket 1, with a front fork plate 2 hinged to the bracket 1; a first rocker plate 3 and a shock absorber component 5 are hinged to the rear end of the front fork plate 2; the front end of the first rocker plate 3 is hinged to a second rocker plate 4; the front end of the second rocker plate 4 is hinged to the front end of the shock absorber component 5, forming a linked shock absorption and steering structure. Through the linked design of the shock absorber component 5 with the first rocker plate 3 and the second rocker plate 4, vibrations during riding can be effectively absorbed. When the motorcycle is riding on uneven roads, the shock absorber component 5 can quickly respond and absorb vibrations, while the hinged arrangement of the first rocker plate 3 and the second rocker plate 4 further disperses and absorbs vibration energy, thereby improving the comfort and stability of the motorcycle. By optimizing the hinge method between the bracket 1, the front fork plate 2, the rocker plate, and the shock absorber component 5, not only is the stability and durability of the structure improved, but a lightweight design is also achieved, allowing the retro motorcycle to maintain its classic appearance while also possessing superior performance and handling.

[0037] The bracket 1 includes a first support rod 101, one end of which is fixedly connected to a second support rod 102. The outer surface of the second support rod 102 has a first hinge position 103 and a second hinge position 104 arranged from top to bottom for hinged connections with the front fork plate 2 and the second rocker plate 4. This allows the front fork plate 2 and the second rocker plate 4 to rotate and tilt flexibly during motorcycle operation, thereby improving the motorcycle's handling performance and stability. The optimized layout of the entire front fork structure makes the connections between components more compact and rational, reducing unnecessary space occupation and weight, achieving a lightweight design.

[0038] The first support rod 101 and the second support rod 102 are fixedly connected by a third support rod 105. The addition of the third support rod 105 forms a triangular support structure, which is a commonly used stable structure in structural mechanics. The triangular structure has excellent stability and can effectively resist forces and vibrations from all directions, thereby ensuring the stability of the fork structure. An inclined reinforcing rod 106 is fixedly connected between the third support rod 105 and the second support rod 102. The inclined reinforcing rod 106 further enhances the stability of the structure. The reinforcing rod 106 not only provides additional support force, but also disperses stress through its inclined angle, making the entire fork structure more robust and durable.

[0039] The fork plate 2 consists of two symmetrically arranged plates. From left to right, the rear end of the fork plate 2 has a third hinge position 201, a fourth hinge position 202, and a fifth hinge position 203; the third hinge position 201 is hinged to the second hinge position 104 of the bracket 1. The rear end of the shock-absorbing assembly 5 is hinged to the fork plate 2 via the fourth hinge position 202; the rear end of the first rocker plate 3 is hinged to the fork plate 2 via the fifth hinge position 203. This allows the fork structure to flexibly respond to various road conditions during operation and also enhances the overall stability and shock absorption performance of the fork structure.

[0040] The second rocker plate 4 has a sixth hinge position 401 on the middle side. The sixth hinge position 401 is hinged to the first hinge position 103 of the bracket 1, which allows the second rocker plate 4 to rotate more flexibly when the motorcycle turns, improving the handling performance of the motorcycle and the comfort of the rider. At the same time, the setting of the sixth hinge position 401 enhances the connection stability between the second rocker plate 4 and the bracket 1.

[0041] An adjusting seat 501 is threaded onto the shock absorber assembly 5. The adjusting seat 501 is used to adjust the damping force of the shock absorber assembly 5. By adjusting the position of the adjusting seat 501, the damping characteristics of the shock absorber assembly 5 can be changed, thereby improving the driving stability and riding comfort of the motorcycle.

[0042] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
