Beschreibung
Zusammenfassung:	An obstacle detection device and a door operator includes a hollow bearing, a slide pin, an output bushing, an elastic member, and a sensor, wherein the slide pin is inserted into a through slot of the hollow bearing. One end of the slide pin is accommodated in an open groove of the output bushing, and the elastic member is accommodated in the hollow bearing and is adapted to apply a biasing force to the slide pin. The sensor is disposed on one side of the open groove of the output bushing. During a normal operation, the hollow bearing drives the output bushing to rotate synchronously through the slide pin. When an obstacle is encountered and the output bushing cannot rotate synchronously with the hollow bearing, the output bushing causes the slide pin to be guided by the open groove and slide, thereby triggering or detriggering the sensor.
