이하, 본 발명의 바람직한 실시예를 예시도면을 참고하여 상세히 설명하고자 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 발명에 따른 오일댐퍼의 구성상태도이다. 도 3의 좌측도면은 오일댐퍼의 외관모습을 나타내고, 도 3의 우측도면은 오일댐퍼의 내부모습을 나타낸다.3 is a configuration diagram of an oil damper according to the present invention. 3 shows the external appearance of the oil damper, and the right view of FIG. 3 shows the internal appearance of the oil damper.

도 3에서 보는 바와 같이, 본 발명에 따른 차량용 오일댐퍼는 차량에 사용되는 기어에 연결 설치되어 회전축의 회전력을 감소시키는 오일댐퍼로써, 댐퍼몸체, 댐퍼뚜껑, 고정스프링 및 회전부재를 포함하여 이루어진다.As shown in Figure 3, the vehicle oil damper according to the present invention is an oil damper connected to the gear used in the vehicle to reduce the rotational force of the rotating shaft, and comprises a damper body, a damper lid, a fixed spring and a rotating member.

댐퍼몸체(174)는 용기형상으로 이루어지며, 양측에는 고정부(174a)가 부착되어 차량의 내부 한쪽에 고정되도록 한다. 댐퍼뚜껑(173)은 댐퍼몸체의 개방부를 밀폐시킨다.The damper body 174 is formed in a container shape, the fixing portion (174a) is attached to both sides to be fixed to one of the interior of the vehicle. The damper lid 173 seals the opening of the damper body.

댐퍼몸체 내부에는 폐쇄고리형태의 고정스프링(172)이 고정된다. 고정스프링 의 고정은 댐퍼몸체의 내측에 고정되거나 댐퍼뚜껑의 내측에 고정될 수 있다. 댐퍼몸체나 댐퍼뚜껑의 어디더라도 상관없이 고정스프링이 댐퍼몸체의 내부에 고정되기만 하면 된다. Inside the damper body, a fixing spring 172 in a closed loop shape is fixed. The fixing spring may be fixed to the inside of the damper body or to the inside of the damper lid. Regardless of whether the damper body or the damper lid is located, the fixed spring may be fixed inside the damper body.

고정스프링은 직사각형의 폐쇄고리형태로 이루어지고, 양단에는 일정한 길이만큼 돌출되도록 절곡되어 고정탄성부(172a)가 형성된다. 고정스프링의 양단의 폭방향 중간에 고정탄성부가 형성된다. 고정탄성부는 고정스프링을 댐퍼몸체 내부에 고정시키고 고정스프링 폭방향의 탄성력을 강화시킨다.The fixed spring has a rectangular closed ring shape, and is bent to protrude by a predetermined length at both ends to form a fixed elastic portion 172a. A fixed elastic part is formed in the middle of the width direction of both ends of the fixed spring. The fixed elastic part fixes the fixed spring inside the damper body and strengthens the elastic force in the fixed spring width direction.

고정스프링의 내측에 회전부재(171)가 위치한다. 회전부재는 기어(150)와 결합되어 회전되면서 기어의 회전속도를 제어시킨다. The rotating member 171 is located inside the fixed spring. The rotating member is coupled to the gear 150 and rotates to control the rotational speed of the gear.

회전부재는 기어와 결합되도록 일측면에 회전축이 부착되고, 회전축은 댐퍼몸체의 외부로 돌출된다. 회전축에 있어서 댐퍼몸체와의 결합부위는 단면상 원형으로 형성되어 회전부재가 댐퍼몸체 내부에서 원활하게 회전된다. 회전축에 있어서 댐퍼몸체의 외부로 돌출된 부위는 각이 지도록 형성되어 기어와의 결합력을 높이고 기어의 회전력이 회전부재에 잘 전달되도록 한다.The rotating member is attached to the rotating shaft on one side to be coupled to the gear, the rotating shaft protrudes out of the damper body. The coupling part with the damper body in the rotating shaft is formed in a circular shape in cross section so that the rotating member rotates smoothly inside the damper body. The projecting portion of the damper body in the rotary shaft is formed to be angled to increase the coupling force with the gear and to transmit the rotational force of the gear well to the rotating member.

회전부재는 원형의 판형상으로 이루어지고, 회전부재의 양단에는 회전지연부(171a)가 돌출 형성된다. 회전지연부를 포함한 회전부재의 길이는 고정스프링의 폭방향의 길이보다 더 길다. 회전부재의 자체 원형부위에서는 고정스프링 내에서 자유롭게 회전되고, 회전지연부에서는 고정스프링 내에서 회전이 지연된다. 즉, 회전지연부를 포함한 길이방향의 회전부재가 고정스프링 내부의 길이방향을 회전할 때는 기어의 회전력을 받아 회전한다. 회전지연부를 포함한 길이방향의 회전부재가 고정스프링 내부의 폭방향을 회전할 때는 기어의 회전력을 지연시키며 회전한다. 따라서 회전부재는 기어의 회전속도를 제어한다. The rotating member is formed in a circular plate shape, the rotation delay portion (171a) protruding from both ends of the rotating member. The length of the rotating member including the rotating delay part is longer than the length of the fixed spring in the width direction. At its own circular part of the rotating member, it is freely rotated in the fixed spring, and rotation is delayed in the fixed spring at the rotation delay part. That is, when the longitudinal rotation member including the rotation delay unit rotates in the longitudinal direction inside the fixed spring, it rotates under the rotational force of the gear. When the longitudinal rotation member including the rotation delay part rotates in the width direction inside the fixed spring, the rotation member retards the rotational force of the gear. Therefore, the rotating member controls the rotation speed of the gear.

본 발명이 적용된 실시예의 구성을 살펴보면, 도 4에서 도시한 바와 같이, 글로브박스의 개폐장치는 차량의 조수석 인스트루먼트패널에 설치되어 물품을 보관하도록 개폐되는 장치이다. 글로브박스의 개폐장치는 제1,2작동로드 사이에 중심기어가 치합된다. Looking at the configuration of the embodiment to which the present invention is applied, as shown in Figure 4, the opening and closing device of the glove box is a device that is installed in the passenger seat instrument panel of the vehicle is opened and closed to store the goods. In the opening and closing device of the glove box, the center gear is engaged between the first and second operating rods.

제1작동로드(144)는 일측부에 제1기어치(146)가 형성되고, 글로브박스(미 도시)의 노브(140)의 작동(누름 또는 당김)에 의해 수평으로 이동한다. 중심기어(150)는 제1기어치(146)에 치합되어 회전축(152)을 중심으로 회전한다. 제2작동로드(160)는 일측부에 제2기어치(162)가 형성되고 제2기어치는 중심기어(150)의 기어치와 치합된다. 본 발명은 제2작동로드가 제1작동로드(144)에 대하여 반대방향으로 작동하여 글로브박스를 개방한다.The first operation rod 144 has a first gear 146 is formed at one side, it is moved horizontally by the operation (push or pull) of the knob 140 of the glove box (not shown). The center gear 150 is engaged with the first gear 146 to rotate about the rotation shaft 152. The second operation rod 160 has a second gear 162 is formed on one side and the second gear tooth is meshed with the gear teeth of the center gear 150. According to the present invention, the second operating rod operates in the opposite direction with respect to the first operating rod 144 to open the glove box.

제1작동로드 일단부에 탄성구(147)의 일단이 연결되고 탄성구의 타단이 글로브박스 일측에 고정된다. 제1작동로드 타단부는 경사지게 로드경사부(143)가 형성된다. 로드경사부와 접하도록 노브 일측에 경사지게 노브경사부(141)가 형성된다. One end of the elastic sphere 147 is connected to one end of the first operating rod and the other end of the elastic sphere is fixed to one side of the glove box. The other end of the first operating rod is inclined rod 143 is formed. The knob inclined portion 141 is formed to be inclined at one side of the knob to contact the rod inclined portion.

노브는 전측의 크기가 후측의 크기보다 크다. 노브는 전측에서 후측으로 갈수록 크기가 줄어드는 형상으로, 전측 외곽에서 후측 중심으로 경사지게 형성되어 노브경사부를 이룬다. 제1작동로드의 로드경사부는 노브경사부와 접촉되어 작동되도록 노브경사부의 경사방향 및 경사각도와 동일하게 경사져 형성된다. The knob is larger than the size of the front side. The knob has a shape that decreases in size from the front side to the rear side, and is inclined from the front outer side to the rear center to form a knob inclination part. The rod inclination part of the first actuating rod is formed to be inclined in the same manner as the inclination direction and the inclination angle of the knob inclination part so as to operate in contact with the knob inclination part.

회전축은 오일댐퍼(151)에 연결되어 회전력이 완화된다. 오일댐퍼가 글로브박스의 일측에 고정되어 회전축은 고정된 상태에서 회전한다.The rotating shaft is connected to the oil damper 151 to reduce the rotational force. The oil damper is fixed to one side of the glove box so that the rotating shaft rotates in a fixed state.

상기와 같이 이루어진 본 발명에 따른 차량용 오일댐퍼의 작용을 본 발명이 적용된 실시예와 함께 살펴보면 다음과 같다.Looking at the action of the vehicle oil damper according to the present invention made as described above with an embodiment to which the present invention is applied.

도 4는 본 발명에 따른 오일댐퍼의 사용상태도이다. 도 4의 상측도면은 오일댐퍼의 사용상태도 정면을 나타내고, 도 4의 하측도면은 오일댐퍼의 사용상태도 평면을 나타낸다.4 is a state diagram used in the oil damper according to the present invention. The upper side view of FIG. 4 shows a front view of the oil damper in use, and the lower side view of FIG. 4 shows a plane of the oil damper in use.

도 4에서 보는 바와 같이 사용자에 의해 노브가 전측에서 후측으로 눌림으로써 노브경사부가 로드경사부와의 접촉경사면을 따라 제1작동로드를 수평 이동시킨다. 제1작동로드가 수평 이동되면 중심기어가 회전하여 제2작동로드를 수평 이동시켜 글로브박스가 개방된다. 사용자가 노브를 누르지 않게 되면 노브에 가해진 눌림이 해제됨으로써 탄성구에 복원력이 작용하여 제1작동로드는 반대방향의 원상태로 수평 이동된다.As shown in FIG. 4, the knob inclined portion moves the first operating rod horizontally along the contact inclined surface with the rod inclined portion by pressing the knob from the front side to the rear side by the user. When the first operating rod is moved horizontally, the center gear is rotated to move the second operating rod horizontally to open the glove box. When the user does not press the knob, the pressing force applied to the knob is released, so that a restoring force is applied to the elastic sphere so that the first operating rod is horizontally moved in the original direction in the opposite direction.

회전축은 오일댐퍼에 의해 서서히 회전하여 탄성구의 복원력에 따른 원상태로의 복귀가 부드럽게 수행되도록 한다. 즉 오일댐퍼는 탄성구의 복원력 발생시 회전력을 완화시킨다.The rotating shaft is slowly rotated by the oil damper to smoothly return to the original state according to the restoring force of the elastic sphere. That is, the oil damper relieves the rotational force when the restoring force of the elastic sphere is generated.

보다 상세히 설명하면, 기어를 강제로 회전시킴에 따라 회전축이 회전하고, 회전축이 회전함으로써 회전부재가 회전한다. 회전부재가 회전하여 회전부재의 양단에 위치한 회전지연부가 고정스프링을 폭방향으로 벌린다. 고정스프링의 탄성에 의해 폭방향의 중간양측이 벌어진다. 이때 댐퍼몸체의 내부에 충진된 오일에 의해 회전부재는 천천히 회전하며, 고정스프링도 부드럽게 벌어진다. In more detail, as the force is rotated, the rotating shaft rotates, and the rotating member rotates by rotating the rotating shaft. As the rotating member rotates, rotation delay parts located at both ends of the rotating member open the fixed spring in the width direction. Due to the elasticity of the fixed spring, the middle both sides in the width direction are opened. At this time, the rotating member is slowly rotated by the oil filled in the damper body, and the fixed spring is smoothly opened.

회전지연부를 포함한 길이방향의 회전부재가 고정스프링 내부의 길이방향을 회전할 때는 기어의 회전력을 받아 회전한다. 회전지연부를 포함한 길이방향의 회 전부재가 고정스프링 내부의 폭방향을 회전할 때는 기어의 회전력을 지연시키며 회전한다. 따라서 회전부재는 기어의 회전속도를 완화시키며 제어한다. When the rotating member in the longitudinal direction including the rotating delay part rotates in the longitudinal direction inside the fixed spring, the rotating member rotates under the rotational force of the gear. When the rotational member in the longitudinal direction including the rotation delay part rotates in the width direction inside the fixed spring, the rotating member retards the rotational force of the gear. Therefore, the rotating member relaxes and controls the rotational speed of the gear.

사용자가 기어를 강제로 회전시키지 않으면 탄성구의 탄성복원력에 의해 회전지연부에는 반대방향으로 회전력이 작용한다. 회전지연부에 작용하는 회전력에 의해 회전부재도 반대방향으로 회전하여 기어를 원상태로 복귀시킨다. 여기서 반대방향은 사용자가 강제로 기어를 회전시킨 회전방향과 반대의 회전방향을 말한다.If the user does not forcibly rotate the gear, the rotational force acts in the opposite direction by the elastic restoring force of the elastic sphere. The rotary member also rotates in the opposite direction due to the rotational force acting on the rotation delay unit to return the gear to its original state. Here, the opposite direction refers to a rotation direction opposite to the rotation direction in which the user forcibly rotates the gear.

이상 설명한 바와 같이 본 발명의 차량용 오일댐퍼는 폐쇄고리형태의 고정스프링을 댐퍼몸체 내부에 고정하고, 고정스프링 내측에 회전부재를 위치시킴으로써, 댐퍼 내부에 회전축과 연결되는 회전핀과, 회전핀에 장착되어야 하는 판스프링이 불필요하여 댐퍼의 내부를 이루는 구성요소의 구조가 단순화되어 제작원가가 절감되고, 회전축의 회전속도를 제어시킬 수 있는 효과를 제공할 수 있다.As described above, the vehicle oil damper of the present invention is fixed to the fixed ring of the closed ring type inside the damper body, by positioning the rotating member inside the fixed spring, the rotary pin connected to the rotating shaft inside the damper, and mounted on the rotary pin Since the leaf spring is not required, the structure of the components constituting the interior of the damper is simplified to reduce the manufacturing cost and provide an effect of controlling the rotational speed of the rotating shaft.
