The invention belongs to the technical field of fairings and particular relates to a fairing with an extending function. The fairing comprises an arc-shaped cover body, the interior of the arc-shapedcover body is of a cavity structure. An open structure is arranged behind the arc-shaped cover body; fixed rotating shafts are arranged at the positions, located on the two sides in the cavity structure, of the rear top of the arc-shaped cover. An extension plate is arranged in the cavity structure; strip-shaped notches are formed in the two sides of the extension plate; the strip-shaped notches are clamped on the fixed rotating shafts on the corresponding sides; a bayonet lock mechanism is arranged at the bottom of the extension plate; automatically extending pin columns are arranged at the two ends of the bayonet lock mechanism; a plurality of circular holes matched with the pin columns are uniformly distributed in the two sides of the arc-shaped cover body; the bottom of the extension plate is fixed by matching the pin columns with the circular holes; and a rotating mechanism for controlling the pin columns to retract is arranged at the bayonet lock mechanism. The defects in the prior art are overcome, the extension plate is arranged between the fairing and the truck box body, the rear portion of the fairing and the top of the truck box body are connected through the extension plate, so that resistance formed due to the fact that the truck box body is higher than the fairing is reduced, and wind resistance is further reduced.

    本发明属于导流罩技术领域,具体涉及一种带有延伸功能的导流罩,包括弧形罩体,弧形罩体内部为空腔结构,弧形罩体后方为开放式结构,弧形罩体后方顶部位于空腔结构内两侧位置均设有固定转轴,空腔结构内设有延伸板,延伸板两侧设有条形槽口,条形槽口卡在对应侧的固定转轴上,延伸板底部设有卡销机构,卡销机构两端均设有自动伸出的销柱,弧形罩体两侧均布有若干个与销柱配合的圆孔,延伸板底部通过销柱和圆孔配合来固定,卡销机构上设有控制销柱回缩的旋转机构,克服了现有技术的不足,在导流罩和货车箱体之间设有延伸板,通过延伸板将导流罩后方和货车箱体顶部连接起来,从而降低由于货车箱体高于导流罩所形成的阻力,进一步降低了风阻。
