Description
본 발명은 댐퍼를 이용한 차고 조절장치에 관한 것으로서, 더욱 상세하게는 차고의 상승 또는 하강시에 모터를 회전시켜 댐퍼 로드의 길이를 자동 조절하도록 하여 빠른 응답성으로 차고를 조절할 수 있도록 하는 댐퍼를 이용한 차고 조절장치에 관한 것이다.The present invention relates to a height control device using a damper, and more particularly, by using a damper to adjust the height of the fast response by rotating the motor to automatically adjust the length of the damper rod when the garage is raised or lowered. It relates to a garage adjustment device.
일반적으로 차량에는 차고 유지 및 차체의 충격력을 완화시키기 위해 댐퍼가 이용되며, 상기 댐퍼는 스프링력에 의해 피스톤 로드를 지지 및 완충력을 제공하게 된다.In general, a damper is used in the vehicle to maintain the height of the garage and to reduce the impact force of the vehicle body, and the damper supports the piston rod by the spring force and provides a cushioning force.
즉, 상기한 댐퍼는 실린더와, 상기 실린더에 삽입되어 전후진 되는 피스톤 로드로 이루어지며, 상기 실린더의 내부에는 유공압 및 가스압을 제공하기 위해 오일 및 가스가 저장된다. That is, the damper is composed of a cylinder and a piston rod inserted into the cylinder to move forward and backward, and the oil and gas are stored in the cylinder to provide oil pressure and gas pressure.
하지만, 상기한 댐퍼의 피스톤 로드에 잦은 충격력이 발생하게 되면 스프링의 탄성력 저하 또는 가스 및 오일의 누설로 피스톤 로드의 각각의 길이가 정확한 수평을 유지하지 못하게 되며, 또한 차량 주행중 선회시에 차체가 한 쪽으로 기울게 되면 이때 로드의 길이를 가변시킬 수 없어 차체가 심하게 기울게 되는 문제점이 있게 된다.However, if frequent impact force is generated on the piston rod of the damper, the elastic force of the spring or the leakage of gas and oil does not allow the length of each piston rod to be accurately leveled. If it is tilted toward the side, the length of the rod cannot be changed, and the vehicle body is inclined severely.
이에 본 발명은 상기와 같은 문제점을 해결하기 위해 창안된 것으로, 본 발명의 목적은 차체의 높이 조절시 모터를 회전시켜 댐퍼의 전체길이를 조절하도록 하므로써 유공압 및 가스압을 이용하지 않고서도 빠른 응답성으로 차고를 조절할 수 있도록 하는데 있는 것이다.Accordingly, the present invention was devised to solve the above problems, and an object of the present invention is to provide a quick response without using oil pressure and gas pressure by rotating the motor to adjust the overall length of the damper when adjusting the height of the vehicle body. It is to be able to control the garage.
본 발명의 다른 목적은, 차량 선회시 또는 노면의 상태에 따라 빠른 응답성으로 차체의 높이를 조절할 수 있도록 하는데 있는 것이다.Another object of the present invention is to be able to adjust the height of the vehicle body with a quick response according to the vehicle turning or road condition.
상기 목적을 달성하기 위한 본 발명은, 차량용 댐퍼에 있어서, 내측에 승하강용 로드를 삽입하며, 하단부에 하향으로 개방된 나사홈을 형성하고, 외주면에는 축방향으로 하향 경사진 다단 걸림턱을 가지고 있는 댐퍼몸체와; 상기 댐퍼몸체를 감싸며 내주면에 회전시 상기 걸림턱이 슬라이드 안내되어 걸림 고정될 수 있도록 경사진 다단 안착턱을 갖는 외통체와; 상기 외통체의 하단부와 일체형으로 결합하며, 내부에 상기 댐퍼몸체의 나사홈에 나사결합되어져 회전시 상기 댐퍼몸체를 승하강 시키게 되는 모터축을 갖는 모터케이스;를 포함하는 것을 특징으로 한다.The present invention for achieving the above object, in the vehicle damper, the lifting rod is inserted into the inner side, to form a screw groove opened downward in the lower end, and the outer peripheral surface has a multi-stage locking step inclined downward in the axial direction A damper body; An outer cylinder body surrounding the damper body and having an inclined multi-stage mounting jaw so that the locking jaw is slide guided and locked when rotated on an inner circumferential surface thereof; And a motor case having a motor shaft which is integrally coupled with the lower end of the outer cylinder and screwed into the screw groove of the damper body to raise and lower the damper body when rotating.
상기 특징에 따라 본 발명은, 차고의 상승 조절시 모터케이스의 모터축이 나사 풀림방향으로 회전하게 되면 댐퍼몸체가 회전 상승하게 되고 동시에 걸림턱이 외통체의 안착턱에 슬라이드 되면서 상승하게 되는 것이다.According to the above feature, when the motor shaft of the motor case is rotated in the direction of loosening the screw during the adjustment of the height of the garage, the damper body is rotated up and at the same time the locking jaw slides up to the seating jaw of the outer cylinder.
이하, 본 발명에 따른 댐퍼를 이용한 차고 조절장치를 첨부된 도면을 참조로 하여 상세히 설명한다.Hereinafter, a garage control apparatus using a damper according to the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 댐퍼의 로드 길이 조절장치를 단면으로 도시한 것으로, 본 발명은 차량용 댐퍼에 있어서, 댐퍼몸체(10)와, 댐퍼몸체(10)의 외면을 감싸는 외통체(20)와, 상기 댐퍼몸체(10)를 승하강 시키는 모터케이스(30)를 포함하여 구성된다.1 is a cross-sectional view showing a rod length adjusting device of a damper according to the present invention, the present invention is a vehicle damper, the damper body 10 and the outer cylinder 20 surrounding the outer surface of the damper body 10 and It is configured to include a motor case 30 for raising and lowering the damper body (10).
상기 댐퍼몸체(10)는, 내측에 차체를 승하강 시키는 로드(11)가 삽입되며, 외측 하단부에는 하향으로 개방된 나사홈(12)이 소정깊이를 가지며 형성되고, 외주면에는 축방향을 따라 하향으로 경사진 다단 걸림턱(13)이 돌출 형성된다. The damper body 10 has a rod 11 for raising and lowering the vehicle body therein, and a screw groove 12 which is opened downward at an outer lower end thereof is formed to have a predetermined depth, and downward on the outer circumferential surface thereof. The multi-stage locking step 13 is inclined to protrude.
상기 외통체(20)는, 중공의 파이프 형상으로 상기 댐퍼몸체(10)를 감싸며 내주면에는 회전시 상기 걸림턱(13)이 슬라이드 안내되어 걸림 고정될 수 있도록 경사진 다단 안착턱(21)이 형성된다.The outer cylinder 20 has a hollow pipe shape surrounding the damper body 10, and an inner circumferential surface is formed with an inclined multi-stage seating jaw 21 so that the locking jaw 13 can be guided and fixed when the locking jaw 13 is rotated. do.
상기 모터케이스(30)는, 상기 외통체(20)의 하단부에 일체형으로 결합하며, 내부에는 상기 댐퍼몸체(10)의 나사홈(12)에 나사결합되어져 회전시 상기 댐퍼몸체(10)를 승하강 시키도록 모터축(31)을 갖는 모터가 구비된다.The motor case 30 is integrally coupled to the lower end of the outer cylinder 20, and screwed into the screw groove 12 of the damper body 10 therein wins the damper body 10 during rotation. A motor having a motor shaft 31 is provided to lower.
여기서, 서로 맞물림 결합되는 상기 걸림턱(13)과 안착턱(21) 중 하나가 탄성체로 이루어지도록 하여 댐퍼몸체의 상승 및 외력 발생시 충격을 흡수할 수 있도록 함이 가능할 것이다.Here, one of the engaging jaw 13 and the seating jaw 21 engaged with each other is made of an elastic body to be able to absorb the shock when the damper body rises and the external force is generated.
또한, 상기 걸림턱(13)과 안착턱(21)이 나선 구조를 가지며 서로 결합되도록 하여 댐퍼몸체(10)의 승하강이 용이하게 이루어지도록 함이 가능할 것이다.In addition, the locking jaw 13 and the seating jaw 21 has a spiral structure to be coupled to each other it will be possible to facilitate the lifting and lowering of the damper body 10.
이상에서와 같이 구성되는 본 발명에 따른 댐퍼를 이용한 차고 조절장치를 첨부된 도면을 참조로 하여 작동상태를 설명한다.With reference to the accompanying drawings the garage control device using a damper according to the present invention configured as described above will be described the operating state.
차고의 높이가 상승되는 경우 도 1에 도시된 바와같이 먼저 모터케이스(30)의 모터가 모터축(31)을 나사 풀림방향으로 회전시키게 되고, 동시에 모터축(31)과 나사결합된 댐퍼몸체(10)가 나사결합에 의해 회전 상승하게 되며, 연속해서 댐퍼몸체(10)의 걸림턱(13)이 회전 상승되면서 외통체(20)의 안착턱(21)에 슬라이드 되면서 안착 또는 정해진 높이까지 계속된 상승을 하며 고정되게 된다.When the height of the garage is increased, as shown in FIG. 1, the motor of the motor case 30 first rotates the motor shaft 31 in a screw release direction, and at the same time, the damper body screwed with the motor shaft 31 ( 10 is rotated to rise by the screw coupling, while the locking jaw 13 of the damper body 10 is rotated and raised in succession while sliding to the seating jaw 21 of the outer cylinder 20 to continue to settle or to a predetermined height Ascend and become fixed.
따라서, 본 발명에 따른 댐퍼를 이용한 차고 조절장치는, 차체의 높이 조절시 모터를 회전시키게 되면 댐퍼가 승하강하게 되고 이에 따라 댐퍼의 길이가 자동 조절되므로써 유공압 및 가스압을 이용하지 않고서도 빠른 응답성으로 차고를 조절할 수 있는 효과가 있다.Therefore, the height control device using the damper according to the present invention, when the motor rotates when the height of the vehicle body is adjusted, the damper is raised and lowered, and thus the length of the damper is automatically adjusted so that quick response without using hydraulic pressure and gas pressure Garage control is effective.
또한, 차량 선회시 또는 노면의 상태에 따라 빠른 응답성으로 차체의 높이를 조절할 수 있는 효과가 있다.In addition, there is an effect that can adjust the height of the vehicle body with a quick response according to the vehicle turning or road conditions.
도 1은 본 발명에 따른 댐퍼를 이용한 차고 조절장치의 단면도.1 is a cross-sectional view of the height control device using a damper according to the present invention.
