The present invention relates to an active bumper (1) suitable for a sensor, which is applied to an autonomous vehicle (100) and comprises: a bumper cover (10) which forms a curvature shape unit around a sensor cover hole (11) through which irradiated light of a LiDAR is discharged; a multiple flap (20) which is coupled to a guide housing (50) formed on the inside of the bumper cover (10) in order to open or close the sensor cover hole (11) by the movement by means of a bent structure; and a flap rotation member (30, 40, 50, 80) which is composed of a rotation member (80) to convert the rotation of a flap rod (40) connected to an actuator (30) into moving power of the multiple flap (20). Therefore, the bumper cover (10) is converted into an open structure only when the LiDAR is operated, in order to prevent the LiDAR from being contaminated or broken due to a rough road, parking or stopping, rain, snow, and bad weather. In particular, the bent type multiple flap (20) can remove the interference of an area of the irradiated light of the LiDAR, thereby achieving freedom in designing the curvature shape at the lower end portion of the bumper cover (10).

    본 발명의 자율주행차량(100)에 적용된 센서 적합형 액티브 범퍼(1)는 라이다의 조사관이 나가는 센서커버 홀(11) 주위로 곡률형상부를 형성한 범퍼커버(10), 범퍼커버(10)의 안쪽에 형성된 가이드 하우징(50)과 결합된 상태에서 굴절 구조에 의한 이동으로 상기 센서커버 홀(11)을 열거나 닫아주는 다중 플랩(20), 액추에이터(30)와 연결된 플랩 로드(40)의 회전을 상기 다중 플랩(20)의 이동력으로 전환시키는 회전부재(80)로 이루어진 플랩회동부재(30,40,50,80)를 포함함으로써 범퍼커버(10)가 라이다 작동시에 만 오픈 구조로 전환되어 험로/주정차/비/눈/악천후에 기인한 라이다 오염 및 파손을 방지하고, 특히 굴절형 다중 플랩(20)으로 라이다 조사광 영역 간섭을 해소함으로써 범퍼커버(10)의 하단부 디자인 곡률형상에 대한 디자인 자유도 확보가 이루어지는 특징을 갖는다.
