Abstract

The invention relates to a driving device for a curtain, which comprises a sliding rod (1), a moving magnet (3), side magnets (5), an intermediate magnet (2) and a reed switch (4), wherein the moving magnet (3) is set to be in sliding type linkage with the sliding rod (1), the curtain is set to be linked with the moving magnet (3), the side magnets (5) are respectively arranged at two ends of the sliding rod (1), the intermediate magnet (2) is arranged at the middle part of the sliding rod (1), the side magnets (5) and the intermediate magnet (2) are arranged on the side edges of the moving magnet (3), and the intermediate magnet (2) is set to be connected with a power supply through the reed switch (4). Therefore, the requirement on thrust for opening and closing the curtain can be satisfied.

Description

1. Technical field [0001] The invention relates to a driving device for curtains, in particular to a driving device for curtains suitable for large-scale office occasions. 2. Background technology [0002] Curtains are widely used as people's daily necessities, so the driving device of curtains is an important device; in people's daily life, curtains are mostly pulled by hand, but there are also electric devices, which are called curtain drive in the applicant's application. In the patent of the device, due to the relatively heavy weight of the curtain, the force between the electromagnet and the permanent magnet is not strong enough, and the sliding distance of the permanent magnet is not very far, which is not enough to drive the curtain to open and close. Even if it can be realized, it needs The power of the electromagnet is very large, which cannot meet the opening and closing requirements of the curtain. 3. Contents of the invention [0003] In order to overcome the ...
