본 고안은 차량용 회전변위센서에 관한 것으로, 더욱 상세하게는 직선변위를 회전변위로 바꾸어 주어서 사용하는 차고 및 연료량센서 또는 트로틀밸브 포지션센서 등에서 발생하는 회전변위를 감지하여 센싱하는 회전변위센서의 진동 방지장치에 관한 것이다.The present invention relates to a rotational displacement sensor for a vehicle, and more particularly, to prevent vibration of a rotational displacement sensor that senses and senses rotational displacement generated from a garage and fuel level sensor or a throttle valve position sensor used by converting a linear displacement into a rotational displacement. Relates to a device.

일반적으로 차량용 회전변위센서는 link 구조를 이용하여 차고의 높이나 연료의 양에 따라 직선적으로 변하는 것을 회전변위로 바꾸어 주거나, 트로틀밸브 포지션 센서 등과 같은 회전 센서에서 생기는 회전변위를 감지하고 이 신호를 주장치에 보내 차량 상태를 점검할 수 있도록 하는데 이용된다.In general, a vehicle rotation displacement sensor uses a link structure to convert a linear change according to the height of the garage or the amount of fuel into a rotation displacement, or detects a rotation displacement generated from a rotation sensor such as a throttle valve position sensor and sends this signal to the main device. It is used to send and check the condition of the vehicle.

이와 같은 목적으로 사용되는 회전변위센서의 하우징에는 자기소자가 마그네트가 함께 내장되어 있다. 제1도는 종래 회전변위센서를 개략적으로 보인 단면도이다.In the housing of the rotation displacement sensor used for this purpose, a magnetic element is built with a magnet. 1 is a cross-sectional view schematically showing a conventional rotational displacement sensor.

이에 도시한 바와 같이, 회전변회센서(21)는 외관을 이루는 하우징(23)에 샤프트(24)와 마그네트(25) 및 자기소자(26)가 내장되어 있다.As shown in the figure, the rotational variation sensor 21 has a shaft 24, a magnet 25, and a magnetic element 26 embedded in a housing 23 forming an external appearance.

샤프트(24)는 하우징(23) 내부에 일단이 내장되며, 샤프트(24) 일단부에 2개의 마그네트(25)가 대칭되게 구성된다. 그리고 금속플레이트를 절단 절곡하여 자기소자(26)가 내장되도록 구성된 홀더(27)를 마그네트(25) 내측으로 삽입되도록 결합 설치한다. 이러한 홀더(27) 내부에 방진제인 실리콘을 충진하여 충격과 진동에 견딜 수 있도록 구성한 후 회로기판(28) 상에 접지 고정시키며, 외부로 노출된 회로기판(28)을 보호하도록 커버(22)를 결합하여 회전변위센서(21)가 완성된다.The shaft 24 has one end embedded in the housing 23, and two magnets 25 are symmetrically configured at one end of the shaft 24. Then, the metal plate is cut and bent to install the holder 27 configured to have the magnetic element 26 embedded therein so as to be inserted into the magnet 25. The holder 27 is filled with silicon as an anti-vibration agent to withstand shock and vibration, and then ground-fixed on the circuit board 28, and the cover 22 is protected to protect the circuit board 28 exposed to the outside. In combination with the rotation displacement sensor 21 is completed.

따라서 종래 회전변위센서(21)는 두 개의 마그네트(25) 사이에 자기소자(26)를 설치하여 회전에 따른 자속밀도 변화를 감지하게 된다.Therefore, the conventional rotational displacement sensor 21 detects a magnetic flux density change due to rotation by installing a magnetic element 26 between two magnets 25.

즉, 샤프트(24)에 마그네트(25)를 별도로 장착한 후, 이를 회전시키면 자기소자(26)에는 일정한 자속밀도가 생겨서 소정의 측정값을 송신한다.That is, when the magnet 25 is separately mounted on the shaft 24 and then rotated, the magnetic element 26 generates a constant magnetic flux density and transmits a predetermined measurement value.

이 때, 샤프트(24)의 회전각도에 따라 고정되어 있는 자기소자(26)에는 단위 면적 변화에 따라 자속밀도 값이 변화됨으로써, 이를 증폭하여 출력을 나타내주면, 어느 일정한 구간에서 선형적인 출력값을 나타내고, 이를 이용하여 회전변위를 센싱하게 되는 것이다.At this time, in the magnetic element 26 fixed according to the rotation angle of the shaft 24, the magnetic flux density value is changed in accordance with the unit area change, thereby amplifying the output to show a linear output value in a certain section. By using this, the rotational displacement is sensed.

그러나 이러한 종래 회전변위센서(21)는 자기소자(26)를 고정하기 위한 홀더(27)가 금속재로 이루어져 자기소자(26)와의 전기적인 접촉이 생길 염려가 있으며, 또한 금속은 두 개의 마그네트(25)에서 생기는 균일한 자계를 방해하여 출력값에 영향을 미치게 된다.However, the conventional rotational displacement sensor 21 has a holder 27 for fixing the magnetic element 26 is made of a metal material may cause electrical contact with the magnetic element 26, the metal is also two magnets (25) This affects the output value by disturbing the uniform magnetic field generated in

즉, 금속재질의 홀더(27)에 의해 자계의 분포가 변하므로 센싱범위가 매우 좁어지며 출력값이 선형적이지 못하는 경우가 발생되고, 금속을 금형으로 가공하여 홀더(27)를 제작하게 됨으로써 제조원가를 상승시키는 요인이 된다. 아울러 자기소자(26)의 위치가 불확실하여 별도의 지그를 이용 하여 조립해야함으로써 작업성 저하로 생산성이 떨어지며 제품 신뢰성이 저하되는 문제점이 있다.That is, since the distribution of the magnetic field is changed by the holder 27 made of metal, the sensing range becomes very narrow and the output value is not linear. The manufacturing cost is reduced by manufacturing the holder 27 by processing the metal into a mold. It is a factor to increase. In addition, since the position of the magnetic element 26 is uncertain, it needs to be assembled using a separate jig, thereby reducing productivity and reducing product reliability due to a decrease in workability.

본 고안은 이러한 문제점을 해결하기 위한 것으로, 본 고안의 목적은 합성수지재로 사출성형되며 소자삽입홈이 형성된 홀더에 자기소자를 결합하고 이를 마그네트 내측에 설치함으로써 자기소자가 홀더에 의해 고정되어 이의 위치가 일정하고 진동이나 충격에 강하며, 홀더 재질이 합성수지재로 구성되어 자계 변화에 영향을 미치지 않아 센서출력이 향상되고 조립이 용이한 차량용 회전변위센서의 진동 방지장치를 제공하는 것이다.The present invention is to solve this problem, the object of the present invention is injection molding of a synthetic resin material and the magnetic element is fixed by the holder by coupling the magnetic element to the holder in which the element insertion groove is formed and installed inside the magnet It is constant and strong in vibration and shock, and the holder material is composed of synthetic resin material, which does not affect the magnetic field change, so that the sensor output is improved and it is easy to assemble the vibration preventing device for the vehicle.

이러한 목적을 달성하기 위한 본 고안은, 하우징에 그 일단이 내장되는 샤프트, 샤프트의 일단부에 대칭되게 설치되는 한쌍의 마그네트, 마그네트 사이에 설치되어 샤프트의 회전에 따른 마그네트의 자계변화를 감지하는 자기소자, 자기소자를 마그네트 사이의 내측에 위치되도록 고정시키며 그 하단부가 회로기판에 결합되는 홀더를 갖춘 차량용 회전변위센서에 있어서,The present invention for achieving the above object, the shaft is installed in the housing one end, a pair of magnets are installed symmetrically on one end of the shaft, the magnet is installed between the magnet to detect the magnetic field change of the magnet according to the rotation of the shaft In the rotational displacement sensor for a vehicle having a holder fixed to the inside of the element, the magnetic element between the magnet and coupled to the circuit board,

홀더는 합성수지재로 사출성형되며 상단 중심부에 자기소자가 끼워져 결합되도록 형성된 소자삽입홈, 하단부에 하향돌출되게 마련되며 회로기판에 끼워져 결합되어 홀더를 고정시키는 고정돌기를 구비하는 것을 특징으로 한다.The holder is injection-molded with synthetic resin material and is provided with a device insertion groove formed so that the magnetic element is fitted into the upper center and coupled to the lower portion. The holder is fitted with a circuit board to be coupled to secure the holder.

이하, 본 고안에 따른 하나의 바람직한 실시예를 첨부도면을 참조하여 상세히 설명한다. 제2도와 제3도는 본 고안에따른 홀더 사시도와 자기소자가 결합된 상태를 보인 단면도이고, 제4도는 본 고안에 따른 회전변위센서의 전체적인 구조를 보인 단면도이다.Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings. 2 and 3 are cross-sectional view showing a holder perspective view and a magnetic element coupled state according to the present invention, Figure 4 is a cross-sectional view showing the overall structure of the rotational displacement sensor according to the present invention.

본 고안에 따른 차량용 회전변위센서(1)은 이들에 도시한 바와 같이, 하우징(3)에 회전가능하게 내장되는 샤프트(4)와 마그네트(5), 마그네트(5)의 회전변위에 따라 자속밀도를 감지하는 자기소자(2) 등으로 크게 구성되어 있다.The rotational displacement sensor 1 for a vehicle according to the present invention has a magnetic flux density according to the rotational displacement of the shaft 4, the magnet 5, and the magnet 5 rotatably embedded in the housing 3, as shown in these. It is largely composed of a magnetic element (2) for detecting the.

하우징(3)에 내장된 샤프트(4) 일단에는 내부에 한쌍의 마그네트(5)가 대칭되게 설치되며, 자기소자(2)는 합성수지재의 홀더(9)를 이용하여 마그네트(5) 사이의 중심에 위치되게 마련된다. 즉, 홀더(9)의 상단 중심부에는 가로방향으로 소자 삽입홈(7)이 형성되어 있어서 여기에 자기소자(2)가 끼워져 결합되며, 하단면에는 고정돌기(8)가 하부로 돌출되게 성형되어 있다. 따라서 고정돌기(8)를 이용하여 이를 회로기판(10)에 끼워 결합하면 자기소자(2)는 샤프트(4) 일단부에 설치된 마그네트(5) 내측에 위치된다.A pair of magnets 5 are symmetrically installed at one end of the shaft 4 embedded in the housing 3, and the magnetic element 2 is centered between the magnets 5 using the holder 9 of a synthetic resin material. It is arranged to be located. That is, the element insertion groove 7 is formed in the center of the upper end of the holder 9 in the transverse direction so that the magnetic element 2 is fitted and coupled thereto, and the fixing projection 8 is formed to protrude downward from the lower surface. have. Therefore, when the fixing protrusion 8 is inserted into the circuit board 10 and coupled, the magnetic element 2 is positioned inside the magnet 5 installed at one end of the shaft 4.

이러한 홀더(9)는 본 고안의 특징적인 요소로 합성수지재로 사출성형됨으로써, 자기소자(2)와의 전기적인 접촉이 발생하지 않으며, 또한 두 개의 마그네트(5)에서 발생되는 균일자계에 아무런 영향을 미치지 않아 회전변위센서(1)의 출력값이 향상되고 센싱 구간도 넓어지게 된다.Since the holder 9 is injection molded of a synthetic resin material as a characteristic element of the present invention, electrical contact with the magnetic element 2 does not occur, and there is no influence on the uniform magnetic field generated by the two magnets 5. Since the output value of the rotational displacement sensor 1 is not improved, the sensing interval is also widened.

즉, 합성수지재로 이루어진 홀더(9)는 중심부위에 가로방향으로 소자삽입홈(7)이 형성되어 자기소자(2)를 견고하게 잡아주고 원하는 위치에 정확하게 설치할 수 있으며, 진동이나 충격이 강하게 된다.That is, the holder (9) made of a synthetic resin material is formed with a device insertion groove (7) in the horizontal direction on the center to hold the magnetic element (2) firmly and accurately installed in the desired position, the vibration or impact is strong.

또한, 홀더(9)는 자계에 영향을 주지 않고, 이의 조립 작업이 용이하여 생산성이 향상되며 제조원가가 절감된다.In addition, the holder 9 does not affect the magnetic field, its assembly work is easy, productivity is improved and manufacturing cost is reduced.

이상에서 상세히 설명한 바와 같이, 본 고안에 따른 차량용 회전변위센서 진동 방지장치는 합성수지재로 사출성형되며 소자삽입홈이 형성된 홀더에 자기소자를 결합하고 이를 마그네트 내측에 설치하였다.As described in detail above, the vehicle rotation displacement sensor vibration preventing device according to the present invention is injection molded with a synthetic resin material and the magnetic element is coupled to the holder formed with the element insertion groove and installed inside the magnet.

따라서 자기소자는 홀더에 의해 고정되어 이의 위치가 일정하게 되고 진동이나 충격에 강하며, 홀더 재질이 합성수지재로 구성되어 자계 변화에 영향을 미치지 않아 센서출력이 향상되고, 조립이 용이하여 제조원가가 절감되며 이의 신뢰성이 향상되는 이점이 있다.Therefore, the magnetic element is fixed by the holder, its position is constant, and it is strong against vibration and shock.The material of the holder is made of synthetic resin material, which does not affect the magnetic field change, so the sensor output is improved, and assembling is easy, manufacturing cost is reduced.
