Description

Technical Field

[0001] The utility model relates to the technical field of electric curtains, in particular to a double-head driving motor for electric curtains. Background Art

[0002] There are two types of electric curtains on the market: single-opening and double-opening. Single-opening electric curtains use a single pulley to drive the curtains from one side of the track to the other side to complete the opening and closing of the curtains, while double-opening electric curtains use double pulleys to drive the curtains from the middle of the track to both sides of the track to complete the opening or closing of the curtains; however, in the existing technology, the driving motor of the double-opening electric curtain can only realize the synchronous and opposite direction movement of the two curtains, that is, the two curtains can only be synchronously opened from the middle position of the window to the two sides or synchronously closed from the two sides of the window to the middle position of the window. There are limitations on the opening and closing of the curtains, and it is impossible to realize the opening and closing of the curtains on one side. In addition, the existing drive motor and the transmission box of the electric curtain are mostly connected by bolts, which is inconvenient to install, takes a certain amount of installation time, and is not convenient for subsequent maintenance. In order to solve this problem, a drive motor mounting structure has also appeared on the market. For example, a Chinese patent application (publication number: CN204928461U) discloses a curtain motor with a new installation and locking device, including a curtain motor, a transmission box installed in conjunction with the motor, and a track arranged on one side of the transmission box. The top of the curtain motor is provided with a motor top cover, the inner wall of the motor top cover is provided with a circumferential groove, one end of the transmission box is provided with a convex rib matching the circumferential groove, the convex rib is stuck in the circumferential groove, and the motor A motor pressure plate is fixed to the top of the top cover by a threaded connection, and a track clip plate is fixed to the end of the transmission box with the rib by a threaded connection. The motor pressure plate is detachably connected to the track clip plate through a locking device, and the locking device includes a paddle arranged between the motor top cover and the motor pressure plate and a toggle assembly arranged on one side of the motor top cover for connecting the paddle and driving the paddle to rotate. The connection state between the motor pressure plate and the track clip plate is controlled by toggling the paddle and the toggle assembly of the locking device. However, the structure of the paddle and the toggle assembly is relatively complex, the production cost is high, and this structure still takes a certain amount of time during installation, resulting in low installation efficiency. Therefore, it is necessary to improve it. Utility Model Content
