계속해서, 도 4에 도시한 바를 참조로 하여, 본 발명에 따른 적재함용 자동 덮개장치(10)의 작용 효과를 설명한다.Next, with reference to FIG. 4, the operation and effect of the automatic lid apparatus 10 for a loading box according to the present invention will be described.

우선, 구동장치(100)가 작동함으로써, 출력축(110)이 회전하고, 이 출력축(110)과 연결부재(150)에 의해 연결된 회동장치(200)의 입력축(201)이 회전함에 따라, 이 입력축(201)과 일체로 형성된 피니언 기어(202)가 회전한다.The output shaft 110 is rotated and the input shaft 201 of the rotating device 200 connected to the output shaft 110 by the connecting member 150 rotates, The pinion gear 202 integrally formed with the pinion gear 201 rotates.

이 피니언 기어(202)의 회전운동은 랙 기어(204)에 의해 직선운동으로 전환되고, 회동장치(200)의 직선운동은 회전축(310) 단부에 구비된 회동 기어(311)에 의해 회전운동으로 전환되며, 덮개프레임(300)이 적재함(5)의 상부에서 개폐된다.The rotary motion of the pinion gear 202 is converted into a rectilinear motion by the rack gear 204 and the linear motion of the rotary device 200 is performed by the rotary gear 311 provided at the end of the rotary shaft 310 And the lid frame 300 is opened and closed at the top of the loading box 5.

도 5에 도시한 것은 본 발명에 따른 적재함용 자동 덮개장치(10)의 다른 실시예를 보인 것이다.(설명 편의상 동일 구성은 동일 명칭을 붙여 설명하되, 부호만 달리 붙여 설명한다)5 shows another embodiment of the lid automatic lid apparatus 10 according to the present invention. (For the sake of descriptive convenience, the same components will be described with the same names,

도시한 바와 같이, 모터(MT)가 일체로 구비된 랙 잭(RJ)을 적재함(5) 외벽 중심에 구비시키고, 수직방향으로 구비된 형성된 랙 기어(RG)는 양측으로 기어(GR)가 형성되어 있다.As shown in the figure, a rack jack RJ integrally provided with the motor MT is provided at the center of the outer wall of the loading box 5, and the rack gear RG formed in the vertical direction is provided with gears GR formed on both sides thereof .

이 랙 기어(RG)는 제 1회동기어(FR)와 기어 결합되어 직선운동을 회전운동으로 전환한다.The rack gear RG is gear-engaged with the first turning gear FR to convert linear motion into rotary motion.

이 제 1회동기어(FR)는 일측에 체인 스프로켓(Chain Sprocket) 또는 타이밍 풀리(Timming Pully)가 일체로 형성된다.A chain sprocket or a timing pulley is integrally formed on one side of the first turning gear FR.

덮개 프레임(CF)의 회전축(RS) 일단에는 상기한 제 1회동기어(FR)와 일체로 형성된 체인 스프로켓(Chain Sprocet) 또는 타이밍 풀리(Timming Pully)와 체인 또는 타이밍벨트 중 어느 하나로 이루어진 연결부재(JM)와 연결된 제 2회동기어(SR)가 구비된다.A chain sprocket or a timing pulley formed integrally with the first turning gear FR and a connecting member made of either a chain or a timing belt are provided at one end of a rotation axis RS of the cover frame CF, And a second rotating gear SR connected to the second rotating shaft JM.

따라서, 회전운동을 직선운동으로 전환시킨 랙 잭(RJ)의 직선운동에 의해 제 1, 2회동기어(FR)(SR)가 회전 하며, 덮개 프레임(CF)이 개폐된다. Therefore, the first and second rotating gears FR rotate due to the linear movement of the rack jack RJ that converts the rotary motion into the linear motion, and the cover frame CF is opened and closed.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 적재함용 자동 덮개장치(10)는 컴팩트한 구성으로 이루어짐으로써, 유지보수가 용이한 덮개장치를 널리 공급하였다.As described above in detail, the automatic lid apparatus 10 for a loading box according to the present invention has a compact structure, and thus widely provides a lid for easy maintenance.
