Description

Technical Field

[0001] This utility model relates to the technical field of novel two-wheeled vehicle parts, specifically to a rear shock absorber connection component for two-wheeled vehicles. Background Technology

[0002] The rear shock absorber connection component of a two-wheeled vehicle typically includes an upper connector, a lower connector, and a spring shock absorber body, with the spring shock absorber body movably connected between the upper and lower connectors. Traditional two-wheeled vehicle frames usually use welded iron tubing or a cast iron frame, especially in scooter models. The rear portion of the frame is often bent into two parallel tubular beams extending rearward. When fixing the spring shock absorber body, the upper connector is fixed to the tubular beams, and the lower connector is fixed to the rear swingarm supporting the rear wheel or the engine. In this type of two-wheeled vehicle structure, most functional components are fixedly mounted on the outside of the frame, and then the frame and functional components are fully or partially wrapped with injection-molded resin exterior parts such as body panels. This traditional frame design suffers from drawbacks such as a large number of assembly connectors, numerous installation steps, and complex production lines. Furthermore, the iron tubing frame and resin products require separate painting lines, leading to high costs and VOC emissions. In addition, coating resins have low recyclability, posing environmental problems.

[0003] The applicant has developed and designed a two-wheeled vehicle frame made of magnesium alloy or aluminum alloy through die casting or thixotropic molding. This frame is particularly suitable for scooters with multiple body panels. This frame structure uses magnesium alloy or aluminum alloy sheets formed by die casting or thixotropic molding to form a basket shape. That is, the frame is assembled from sheets of magnesium alloy or aluminum alloy that have been die-cast or cast. This frame is located directly on the outside of the entire vehicle body, while the relevant functional components are located inside the basket-shaped frame. There is no need for external body parts that cover the relevant functional components, reducing the use of resin external parts. However, since this basket-shaped frame structure does not have the tubular beams of existing frame technology, it is not possible to directly fix the upper connecting parts and rear shock absorption structure support to the basket-shaped frame structure. It is necessary to set up reasonable two-wheeled vehicle rear shock absorption connection components to match this new basket-shaped frame structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a rear shock absorption connecting component for two-wheeled vehicles, and to solve the technical problem of how to reasonably combine and configure the rear shock absorption connecting component of a scooter with the basket-type frame structure when using an advanced existing magnesium alloy or aluminum alloy basket-type frame structure.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] The rear shock absorber connection component of a two-wheeled vehicle includes a spring shock absorber body. The frame of the two-wheeled vehicle includes a storage box rear frame plate. The storage box rear frame plate includes a basket rear side panel and a basket bottom plate. The basket bottom plate is provided with a rear shock absorber mounting boss that matches the spring shock absorber body. The upper end of the spring shock absorber body is mounted on the rear shock absorber mounting boss. The basket rear side panel, basket bottom plate, and rear shock absorber mounting boss are all made of magnesium alloy or aluminum alloy and integrally formed by die casting.

[0007] The rear shock absorber connection component of the two-wheeled vehicle using the above technical solution can be applied to the use of advanced existing magnesium alloy or aluminum alloy basket-type frame structures, allowing the rear shock absorber connection component of the scooter to be reasonably matched and installed with such basket-type frame structures.

[0008] The structure of the rear shock absorber connection component is further defined by including an upper connector and a lower connector. The spring shock absorber body is movably connected between the upper connector and the lower connector. The upper connector includes an upper flat top surface, a left side surface, and a right side surface. The upper flat top surface, left side surface, and right side surface are integrally formed vertical cross-sections in a gate-shaped shape. At least two vertical upper flat top surface mounting holes are provided on the upper flat top surface. At least two vertical upper mounting boss mounting holes are also provided on the upper mounting boss of the rear shock absorber. The upper mounting boss mounting holes correspond in position and shape to the upper flat top surface mounting holes. The upper connector is fixed to the outside of the upper mounting boss of the rear shock absorber by bolts passing through the vertical upper flat top surface mounting holes and the vertical upper mounting boss mounting holes. The upper end hinge of the spring shock absorber body is between the left side surface and the right side surface.

[0009] Using this upper connector method allows for a more secure fixation of the rear shock absorber to the basket-type frame.

[0010] Further specifying, the basket bottom plate is also provided with a rear horizontal fork mounting boss that matches the rear horizontal fork of the two-wheeled vehicle. The rear horizontal fork mounting boss is provided with a transverse horizontal fork mounting hole. The front end of the rear horizontal fork of the two-wheeled vehicle is hinged to the outside of the rear horizontal fork mounting boss by bolts passing through the horizontal fork mounting hole. The lower connecting piece is provided at the rear section of the rear horizontal fork. The lower end of the spring shock absorber body is hinged to the lower connecting piece. The rear side panel of the basket, the basket bottom plate, the rear shock absorber mounting boss and the rear horizontal fork mounting boss are all made of magnesium alloy or aluminum alloy and integrally formed by die casting.

[0011] The aforementioned structural limitations can better define the specific installation positions and fixing methods of the upper and lower connectors.

[0012] In addition, the rear shock absorber is provided with at least two sets of vertical mounting holes, and each set of mounting holes corresponds to the vertical mounting holes on the top surface.

[0013] This multi-position design achieves the function of multiple slots while avoiding the slippage issue that can occur with slotted holes.

[0014] In addition, the rear shock absorber mounting boss is provided with a transverse rear shock absorber upper mounting hole, and the upper end of the spring shock absorber body is connected to the rear shock absorber mounting boss by bolts passing through the transverse rear shock absorber upper mounting hole.

[0015] This method of fixing the upper end of the rear shock absorber horizontally eliminates the need for an upper connector. The upper end of the rear shock absorber can be fixed to the upper mounting boss by directly passing a horizontal bolt through the horizontal mounting hole of the rear shock absorber and the upper mounting through hole of the rear shock absorber, which is simpler.

[0016] The rear shock absorber connection component of the two-wheeled vehicle using the above technical solution is better suited for the basket-like frame made of magnesium alloy or aluminum alloy through die casting. With this fit and bolt fixing structure, the installation of the rear shock absorber of the two-wheeled vehicle can be realized. Attached Figure Description

The upper end hinge of the spring shock absorber body 3 is between the left side 22 and the right side 23. The front end of the rear horizontal fork 5 of the two-wheeled vehicle is fixed to the outside of the rear horizontal fork mounting boss 122 by bolts passing through the horizontal fork mounting hole 1221. The lower connecting piece 4 is provided at the rear section of the rear horizontal fork 5, and the lower end hinge of the spring shock absorber body 3 is on the lower connecting piece 4.

[0027] The rear side panel 11, bottom plate 12, rear shock absorber mounting boss 121, and rear flat fork mounting boss 122 of the basket are all made of magnesium alloy or aluminum alloy and integrally formed by die casting.

[0028] Example 2, as Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the rear shock absorber mounting boss 121 has two sets of vertical mounting boss holes 1211, each set of mounting boss holes 1211 corresponding to the vertical upper flat surface mounting holes 211. Embodiment 2, with its two sets of vertical mounting boss holes 1211 on the rear shock absorber mounting boss 121, allows for adaptive adjustments based on different rear wheel widths and rear shock absorber mounting angles, without requiring a change to the chassis, thus offering wider adaptability.
