본 고안은 예컨대 음향 기기의 턴테이블, VTR의 프론트로딩 시스템, TV수상기등의 원격 조정기 수납용 서랍등과 같은 전자기기의 왕복 운동부 이젝팅 댐핑장치에 관한 것이다.The present invention relates to a reciprocating part ejection damping device of an electronic device such as a turntable of a sound device, a front loading system of a VTR, a drawer for receiving a remote controller such as a TV receiver, and the like.
종래 이런 종류의 이젝팅 장치에서는 이젝팅 속도를 일정하게 유지하기 위하여 감속 모우터를 사용하는 것이었으므로 구조가 복잡하고, 비경제적으로 되는 폐단이 있었다.Conventionally, this type of ejecting device uses a deceleration motor in order to maintain a constant ejecting speed, so there is a closed structure that is complicated and uneconomical.
따라서 본 고안은 이러한 종래의 폐단을 해소하고 간단한 구조로써 원활한 댐핑 효과를 발휘할 수 있는 전자기기의 왕복운동부 이젝팅 댐핑장치를 제공하려는 것으로 이를 첨부도면에 따라서 상세히 설명하면 다음과 같다.Accordingly, the present invention is to provide a reciprocating part ejection damping device of the electronic device that can solve the conventional closed end and exhibit a smooth damping effect as a simple structure, which will be described in detail according to the accompanying drawings.
도면에 있어서(1)은 본 고안의 댐핑장치가 적용되는 전자기기의 왕복운동부의 일예를 도시하는 왕복운동부 본체로서 그 내부에 왕복대(2)가 왕복운동 가능하게 삽설되어 로울러(3)에 권취 반전된 스프링(4)에 의해 상시 이젝트되는 방향으로 탄설되어 있다.1 is a reciprocating part main body showing an example of a reciprocating part of an electronic device to which the damping device of the present invention is applied, and a reciprocating part 2 is inserted therein to enable reciprocating motion and wound around the roller 3. It is piled up in the direction always ejected by the inverted spring 4.
상기 왕복대(2)의 일측면에는 랙(5)이 착설되어 본체(1)의 일측에 천설된 통공(6)에서 노출되어 있다.The rack 5 is mounted on one side of the carriage 2 and is exposed at the through hole 6 installed at one side of the main body 1.
본체(1)의 통공(6) 외측에는 댐퍼 피니언(8)이 회전 가능하게 지지된 한쌍의 댐퍼 케이싱(7)이 고정부착 되어 있다.A pair of damper casings 7 in which the damper pinion 8 is rotatably supported is fixedly attached to the outside of the through hole 6 of the main body 1.
상기 피니언(8)은 통공(6)을 통하여 랙(5)에 치합된다.The pinion 8 is engaged with the rack 5 via the aperture 6.
상기 피니언(8)의 회전축(9)에는 다수(도면에서는 3개)의 마찰원판(10)이 고정되어 있으며, 케이싱(7)의 내부에는 상기 마찰원판(10)이 유삽되는 반원홈(11)이 요설되어 있다.A plurality of friction disks 10 are fixed to the rotation shaft 9 of the pinion 8, and a semicircular groove 11 into which the friction disk 10 is inserted is inserted into the casing 7. This is the theory.
상기 마찰원판(10)과 반원홈(11) 사이의 공간에는 점성유체(12)가 주입되어 마찰원판(10)과 점성유체(12)간의 마찰에 의해 피니언(8)의 히전을 감속시키도록 구성되어 있다.The viscous fluid 12 is injected into the space between the friction disc 10 and the semicircular groove 11 to reduce the current of the pinion 8 by friction between the friction disc 10 and the viscous fluid 12. It is.
상기 점성유체(12)는 점도가 높은 오일을 사용하면 된다.The viscous fluid 12 may be a high viscosity oil.
미설명부호(13)은 댐퍼케이싱(7)을 나사(14)로 고정하기 위한 보스(BOSS)부이다.Reference numeral 13 is a boss (BOSS) for fixing the damper casing (7) with a screw (14).
이러한 구성의 본 고안은 왕복대(2)가 스프링(4)에 의하여 이젝팅 됨에 있어서, 상기 랙(5)이 왕복대(2)와 일체로 직선운동을 하게되며, 랙(5)에 치합된 피니언(8)이 회전하게 된다.According to the present invention of the configuration, the carriage 2 is ejected by the spring 4, so that the rack 5 is linearly integrated with the carriage 2, and is engaged with the rack 5 The pinion 8 will rotate.
이때 피니언(8)의 회전축(9)에는 케이싱(7)의 반원홈(11) 내에서 회전하면서 점성유체(12)가 마찰접촉하는 마찰원판(10)이 고정되어 있으므로 마찰원판(10)과 점성유체(12)간의 마찰에 의해 회전축(9) 즉 피니언(8)의 회전을 감속시키게 되며 이에 따라 피니언(8)에 치합된 랙(5)이 직선운동이 감속되어 왕복대(2)의 이 팅 댐핑이 이루어지는 것이다.At this time, the friction disc 10 and the viscous fluid 12 are fixed to the rotation shaft 9 of the pinion 8 while the viscous fluid 12 is in friction contact with the rotating shaft 9 of the casing 7. Due to the friction between the fluids 12, the rotation of the rotation shaft 9, that is, the pinion 8, is slowed down. Accordingly, the linear motion of the rack 5 engaged with the pinion 8 is decelerated so that the fitting of the carriage 2 can be reduced. Damping is done.
이상과 같이 본 고안에 의하면 마찰원판과 점성유체에 의해 감속되는 피니언에 왕복대 측면에 고정된 랙을 치합하는 것만으로써 왕복대의 이젝팅 댐핑을 효과적으로 행할 수 있으므로 구조가 간단하여 제작이 간편하고 제조원가를 절감할 수 있는 등의 효과가 있다.As described above, according to the present invention, the ejection damping of the carriage can be effectively performed by simply fitting the rack fixed to the side of the carriage to the pinion which is decelerated by the friction disc and the viscous fluid, so the structure is simple and the manufacturing cost is simple. It can reduce the effect.
또한 본 고안은 단지 직선운동을 하는 왕복대 뿐만 아니라, 선회 운동을 하는 개폐도어(카세트 녹음기의 데크등)에서 적용할 수 있으며, 이 경우 상기 랙을 개폐도어의 선회 반경에 따라 원호상으로 형성하면 되는 것이다.In addition, the present invention can be applied not only in the linear motion, but also in the opening and closing doors (cassette recorder deck, etc.) of the swinging movement, in this case, if the rack is formed in an arc shape according to the turning radius of the opening and closing doors Will be.
