The invention discloses an impact-resistant bumper air duct which is characterized in that a bumper body and an air duct body are included, an air duct mounting groove with the rectangular cross section is formed in the bumper body, an impact frame is arranged in the air duct mounting groove in a sliding mode, a covering plate is hinged to the outer end face of the impact frame, and rack sections are formed on the left surface and the right surface of the impact frame; gears meshed with the rack sections are hinged to the interior of the impact frame, arc-shaped reinforcing plates are arranged on the gears, reset springs are connected to the inner end face of the impact frame, the brake disc is cooled while wind resistance is reduced, air flow in the air duct is attenuated, and excessive outlet air flow is avoided. The arc-shaped reinforcing plates are arranged and support the covering plate in the collision process, and the impact resistance of the bumper is improved.
本发明公开了一种抗冲击保险杠风道,其特征在于保险杠本体、风道本体,在保险杠本体内部开设有横截面为矩形的风道安装槽,风道安装槽内部滑动设置有撞击框,撞击框的外端面铰接有覆盖板,撞击框左右表面形成有齿条段,撞击框内部铰接有分别与齿条段进行啮合的齿轮,齿轮上设置有圆弧形加强板,撞击框内端面连接有复位弹簧,减轻风阻同时对刹车盘进行降温,对风道内的气流进行衰减,避免出口气流过大,设置圆弧加强板,在碰撞时支撑覆盖板,提升了保险杠的抗冲击性能。
