내측 스윙도어 구동장치는 모터(1), 모터(1)로 구동하는 웜기어-웜 감속기, 확동 클러치(2), 잠금해제 에어실린더(3)와 잠금해제 연결기구를 포함하고, 상기 확동 클러치(2)는 내부 기어(201), 외부 기어(202)와 탄성 소자(12)를 포함하며, 내부 기어(201)와 웜기어-웜 감속기는 전동 연결하고, 외부 기어(202)는 내측 스윙도어의 도어축과 동축 전동하며, 잠금해제 에어실린더(3)는 에어실린더 푸시로드(301)를 포함하는 데, 잠금해제 연결기구의 일단이 에어실린더 푸시로드(301)의 단부와 접촉하고, 잠금해제 연결기구의 다른 일단이 내부 기어(201)와 서로 연결되며; 잠금해제 에어실린더(3)에 공기가 진입할 때, 에어실린더 푸시로드(301)가 잠금해제 연결기구를 밀어 움직이고, 잠금해제 연결기구는 내부 기어(201)를 이동하여 외부 기어(202)와 맞물리도록 함으로써, 탄성 소자(12)를 압축하며; 잠금해제 에어실린더(3)가 공기를 배출할 때, 내부 기어(201)는 탄성 소자(12)의 탄성회복력 작용 하에, 외부 기어(202)와 서로 이탈한다. 본 발명에 따른 구동장치는 모듈화 설계를 이용하므로, 부속품이 적고, 구조가 심플하며, 조립에 편리하고, 체적이 작으며, 적용성이 우수하고, 잠금이 더욱 더 믿음직하며, 기구의 안정성이 좋다. The present disclosure discloses an inward-swing door driving device, including a motor, a worm wheel and worm reducer driven by the motor, a positive clutch, an unlocking cylinder and an unlocking connecting mechanism. The positive clutch includes an inner tooth, an outer tooth and an elastic element. The inner tooth is in transmission connection with the worm wheel and worm reducer, and the outer tooth is in coaxial transmission with a door shaft of an inward-swing door. The unlocking cylinder includes a cylinder push rod. One end of the unlocking connecting mechanism is in contact with the end portion of the cylinder push rod, and the other end of the unlocking connecting mechanism is connected with the inner tooth. When air is fed into the unlocking cylinder, the cylinder push rod pushes the unlocking connecting mechanism, and the unlocking connecting mechanism drives the inner tooth to mesh with the outer tooth and compress the elastic element. When the air in the unlocking cylinder is discharged, the inner tooth and the outer tooth demesh under the action of resilience force of the elastic element. The driving device of the present disclosure uses a modularization design, so that the driving device has a small number of parts, and is simple in structure, convenient to assemble, small in volume, good in applicability, more reliable in locking and good in mechanism stability.
