Description

Technical Field

[0001] This utility model relates to the technical field of novel two-wheeled vehicle parts, specifically to a novel two-wheeled vehicle steering column structure. Background Technology

[0002] The existing steering column structure includes a steering column body, a lower connecting plate body, and a head tube. The lower end of the steering column body is connected to the lower connecting plate body, and the upper end of the steering column body is fitted inside the head tube. Since existing vehicle frames are typically constructed using welded iron pipes, and the head tube is made of forged or shaped iron pipe, the designed functional components are then fixed to the frame. For example, the head tube is welded to the front end of the central frame. Then, external components made of injection-molded resin, such as front covers, left and right windshields, and body panels, are used to wrap or partially wrap the functional components and the central frame. This serves both to protect the internal functional components and for decorative purposes. The head tube and frame are manufactured separately. This structure is simple in design and stable in structure. However, with the improvement of material technology and national policies to reduce the use of resin products… To meet the demands, a new type of two-wheeled vehicle frame has emerged, constructed from magnesium or aluminum alloy through die casting or thixochemical molding. This frame is particularly suitable for scooters with multiple body panels. This frame structure uses magnesium or aluminum alloy, die-cast or thixochemically molded into a basket-shaped frame. Specifically, the frame is assembled from sheet metal die-cast or cast magnesium or aluminum alloy, and it sits directly on the exterior of the vehicle body. All functional components are housed inside the basket-shaped frame. This structure eliminates the need for external body panels that obscure functional components, reducing the use of resin-based external components. However, if this frame structure uses the existing head tube in the steering column structure, fixing the iron tube head tube to the steering column structure of this new frame is a technical problem that needs to be solved. Existing welding or fixed assembly methods suffer from inaccurate positioning and complex processes. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a new type of steering column structure for two-wheeled vehicles, and to solve the technical problem of how to fix the head tube to this new type of steering column structure when using advanced existing magnesium alloy or aluminum alloy frames.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A novel two-wheeled vehicle steering column structure includes a steering column body, a lower connecting plate body, and a vertically arranged head tube. The lower connecting plate body is connected to the lower end of the steering column body. The steering column body is fitted inside the head tube from bottom to top. The head tube and the frame of the two-wheeled vehicle are integrally formed from magnesium alloy or aluminum alloy by die casting or thixotropic bonding.

[0006] Further defining the two-wheeled vehicle, the frame includes a front structure, the front structure includes a front head panel, the front head panel includes an outer head panel and an inner head panel, the head tube is fixed to the inner head panel, and the outer head panel, the inner head panel and the head tube are integrally formed.

[0007] Furthermore, the inner fascia of the vehicle head includes a bottom inner fascia plate and an upper inner fascia support plate. The bottom inner fascia plate is concave inward to the rear of the two-wheeled vehicle, forming a curved surface. The inner fascia support plate is located above the bottom inner fascia plate and is perpendicular to the head tube.

[0008] Furthermore, a vertical left reinforcing plate and a right reinforcing plate are provided on the side of the head tube, and the left reinforcing plate and the right reinforcing plate are integrally formed with the head tube; a front reinforcing plate is provided at the front of the head tube, and the front reinforcing plate is integrally formed with the head tube.

[0009] In addition, the front structure also includes a front rear bulkhead, the front bulkhead and the front rear bulkhead are connected to form a front cavity with an upper opening, the front cavity accommodating the head tube and the lower end of the two-wheeled vehicle's handlebar assembly.

[0010] The novel two-wheeled vehicle steering column structure employing the above-mentioned technical solution solves the technical problem of how to fix the head tube to the steering column structure of the existing magnesium alloy or aluminum alloy frame when using advanced magnesium alloy or aluminum alloy frames. By using low-melting-point, lightweight, and highly recyclable metal materials such as magnesium alloy or aluminum alloy, and forming them integrally or partially through die casting or thixotropic molding, a lightweight, high-rigidity, and environmentally friendly scooter steering column structure is achieved.

[0017] In the above technical solution, the head tube 13 is a hollow cylindrical component supporting the steering column mechanism, arranged above the front structure, and transmits the steering load and road impact load to the lower front shock absorber and front wheel structure; the inner front panel 112 is formed in a concave dome shape to prevent foreign objects splashed up by the front wheels from entering, and its inner side is combined with the lower end of the head tube 13 to ensure space to adapt to the front wheel steering angle; the front front panel 111, while forming the appearance design, together with the inner front panel 112, forms a box-shaped structure to enhance the overall torsional rigidity and vertical rigidity; the enclosure of the inner front panel 112 and the front front panel 111 ensures rigidity. In addition, a front reinforcing plate 133, a left reinforcing plate 131, and a right reinforcing plate 132 are added between the middle section of the head tube 13 and the front front panel 11 to further enhance the strength of the head tube 13 and improve its rigidity.

[0018] In addition, the frame of this utility model can also be reinforced with internal reinforcing ribs and reinforcing planes to enhance its strength and rigidity.
