Disclosed is a power generating apparatus for a vehicle tire, which is attached to a vehicle tire, converts vibration energy, impact energy and deformation energy into electric energy, and has a simple and efficient structure. The power generating apparatus for a vehicle tire according to an embodiment of the present invention comprises: a permanent magnet, a coil, a pair of springs, a piezoelectric element, and an energy storage part. The coil is wound to be spaced apart from the permanent magnet on the outside of the permanent magnet. The pair of springs provide elastic restoring force to the permanent magnet by being connected to the upper part and the lower part of the permanent magnet. The piezoelectric element is coupled between the permanent magnet and the springs. The energy storage part is electrically connected to the coil and the piezoelectric element to store energy generated from the coil and the piezoelectric element.

    차량의 타이어에 부착되어 차량의 진동에너지와 충격 및 변형에너지를 전기에너지로 변환하는, 구조가 간단하고 효율이 좋은 차량 타이어용 자가 발전 장치가 개시된다. 본 발명의 일 양상에 따른 차량 타이어용 자가 발전 장치는 영구자석, 코일, 한 쌍의 스프링, 압전소자, 에너지 저장부를 포함한다. 코일은 영구자석의 외측에 영구자석과 이격하여 권취된다. 한 쌍의 스프링은 영구자석의 상부와 하부에 연결되어 영구자석에 탄성복원력을 제공한다. 압전소자는 영구자석과 스프링 사이에 결합된다. 에너지 저장부는 코일 및 압전소자에 전기적으로 연결되어 코일 및 압전소자에서 발생한 에너지를 저장한다.
