Abstract
Description
Technical Field
[0001] This utility model relates to curtain motors, and more particularly to a structure in which the housing and circuit board of a curtain motor are mounted on the housing. Background Technology
[0002] With the development of smart homes, people are increasingly using motorized curtains to open and close them. The curtain motor is the power source for motorized curtains, and the circuit board installed inside the motor is a crucial component. Currently, most curtain motor housings are cylindrical or rectangular in cross-section, with the circuit board vertically mounted inside. To accommodate the circuit board, specific placement space is needed inside the housing, and vertical slots are provided on the inner side of the housing to secure it. While this provides stable mounting, it requires significant installation space, resulting in a larger curtain motor size. This not only increases production costs but also negatively impacts the aesthetics of the curtain system and interior decoration. Utility Model Content
