WIPO Patent Application WO/2017/185286

A1

Provided is a swing control device for a baby product, comprising: a speed reduction gear box upper cover (1), a motor (6), and a speed reduction gear box base (11). The motor (6) is located on the speed reduction gear box base (11), a first speed reduction gear wheel (7) is secured on a drive shaft of the motor (6), the first speed reduction gear wheel (7) engages with a second speed reduction gear wheel (8), the second speed reduction gear wheel (8) engages with a third speed reduction gear wheel (9), and the third speed reduction gear wheel (9) engages with a fourth speed reduction gear wheel (10). A gear signal emission source (5) is provided inside the speed reduction gear box base (11) and is formed from a gear (51) and a rotating shaft (52) that are integrated by means of injection molding. The gear (51) of the gear signal emission source (5) engages with the first speed reduction gear wheel (7). The rotating shaft (52) of the gear signal emission source (5) is connected to a photoelectric signal sensor (3) located outside the speed reduction gear box upper cover (1). A photoelectric sensing signal receiver (4) is located at an edge of the photoelectric signal sensor (3), and the photoelectric sensing signal receiver (4) and the photoelectric signal sensor (3) are in a receiving state. The device of the present invention has advantages of a novel structure, stable operation, and stable signal output.
