Description

Technical Field

[0001] The invention relates to a motorcycle tail mounting structure, in particular to a motorcycle tail center cover and a rear air guide cover mounting structure. Background Art

[0002] As a functional part of mid-to-high-end products, the motorcycle rear air guide plays the role of guiding the rear wind during the driving of the motorcycle. It is usually installed as an accessory on both sides of the outside of the rear center cover. The two are usually connected by screws. The standard configuration of the rear center cover requires reserved screw holes for installation before leaving the factory. The exposed screw holes not only destroy the appearance of the existing parts; at the same time, the rear air guide is installed as an accessory, which affects the integrity of the rear parts.

[0003] The existing rear plastic parts of motorcycles are usually connected to each other as well as to the frame. The frame is provided with a metal bracket for installing the plastic parts, and the bracket is welded to the frame. The plastic parts are injection molded, which increases the cost of parts, the quality of the whole vehicle and the assembly error between parts. The gap consistency between plastic parts is poor; the assembly is complicated and the weight of the whole vehicle is increased. Summary of the invention

[0009] Among them, the rear right air guide cover and the rear left air guide cover are respectively arranged in the hollow parts on the left and right of the tail center cover, presenting an envelope structure, which is convenient to install and disassemble, and reduces the cost of parts.

[0010] Among them, the rear right air guide cover and the rear left air guide cover are symmetrically provided with a right first card slot, a right second card slot, a left first card slot, and a left second card slot, respectively. The right second card slot and the left second card slot cooperate with the bottom of the front connecting part, and the right first card slot and the left first card slot cooperate with the bottom of the side connecting part, and the width of the card slot is consistent with the bottom wall thickness.

[0011] Among them, the first right slot, the second right slot, the first left slot or the second left slot are in a V-shape or a square shape, and the slots are snap-fitted with the front connecting part and the side connecting part, and are connected with through-hole bolts, so that the tail center cover and the rear right air guide cover and the rear left air guide cover are more stable and reliable, and the connection between the components is tighter, ensuring the integrity of the parts.

[0012] Wherein, the rear ends of the rear right air guide cover and the rear left air guide cover are respectively provided with transverse air guide ports.

[0013] Wherein, the central axis of the cover plate is provided with a mounting hole, which is connected to the mounting column arranged at the corresponding position of the rear center cover by means of screws.

[0014] Wherein, a through hole is provided at the rear end of the rear center cover, which is connected to the mounting column of the rear taillight assembly by screws.

[0015] Among them, the right rear tail cover and the left rear tail cover are provided with through holes, which are connected to the mounting columns arranged at corresponding positions on the helmet box, the rear right air guide cover and the rear left air guide cover through bolts.

[0016] The rear center cover is symmetrically provided with through holes, and is connected to the mounting posts of the rear right air scoop and the rear left air scoop by bolts.

[0017] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: the present invention ensures the integrity of the rear parts, the screw holes are not exposed, and the appearance is beautiful; the rear right air guide cover, the rear left air guide cover, the tail center cover and the surrounding parts are all injection molded, and can form complex appearance parts with low parts cost. At the same time, the components cooperate with each other, reducing the cumulative installation errors of the parts, and the assembly is simple and easy to operate, which improves the assembly efficiency.
