Abstract
본 발명은 회전각 이외의 잡음을 제거할 수 있는 정육면체 압전회전각 센서에 관한 것이다.The present invention relates to a cube piezoelectric rotation angle sensor capable of removing noise other than the rotation angle.
본 발명은 주위 온도변화에 의해 감도가 영향을 받게되는 문제점을 해결하기 위하여 주위온도변화에 의한 감도 변화를 방지할 수 있는 전단형 정육면체 3차원 압전회전각 센서를 제공하는데 그 목적이 있다.An object of the present invention is to provide a shear-type cube three-dimensional piezoelectric rotation angle sensor that can prevent the sensitivity change due to the ambient temperature change in order to solve the problem that the sensitivity is affected by the ambient temperature change.
본 발명은 향탄성 금속체의 일측 중앙부에 경방향으로 분극처리된 원통형 압전소자인 구동부가 삽입되고, 외측부가 질량체이고 내측부가 전단형으로 분극처리된 압전소자로 이루어진 감지부로 구성되는 것을 특징으로 하고 감지부센서로 사용된 압전소자가 주위온도변화에 의한 감도변화를 방지하고 통상의 압축용력에 의한 전하발생을 취하는 회전각 센서에 비하여 고감도의 측정이 가능하므로 소형화에 유리한 효과가 있게된다.The present invention is characterized in that the drive portion is a cylindrical piezoelectric element polarized in the radial direction at one side central portion of the anti-elastic metal body is inserted, the outer portion is a mass body and the inner portion is composed of a sensing portion consisting of a piezoelectric element polarized in shear type The piezoelectric element used as the sensor of the sensing part prevents the sensitivity change due to the change of the ambient temperature and can measure the high sensitivity as compared to the rotation angle sensor which takes the charge generation by the normal compression force, which is advantageous in miniaturization.
