Description

Technical Field

[0001] This utility model relates to the field of electric curtain technology, and more specifically to a dual-output adjustable curtain motor. Background Technology

[0002] Among the electric curtains, there are left and right opening and closing curtains, which allow the left and right curtains to open and close independently. In the above-mentioned opening and closing curtains, the curtain motor includes two sets of power components. The output ends of the two sets of power components are arranged flush and connected to the input ends on the corresponding transmission box.

[0003] However, after improving the opening and closing of the curtains, both ends of the left curtain and both ends of the right curtain are individually controlled. This requires a power unit to control the two sets of drive belts. An additional drive unit is needed to adjust the output position of the power unit. However, if the two drive units are set separately, it is difficult to ensure that the output positions of the drive units are aligned. This may result in a difference in output position between the two power units. When docking with the input of the transmission box, the opposing force between the higher output position and the input of the transmission box may be too great and cause damage.

Each track groove is connected to a drive belt. Four drive gears are rotatably connected in the main drive box and the auxiliary drive box, corresponding to the four drive belts.

[0044] When the drive component 3 drives the power component 2 to the lower end, the output end of the power component 2 is connected to the transmission belt at the lower track groove in the groove group.

[0045] When the drive component 3 drives the power component 2 to the upper end, the output end of the power component 2 is connected to the transmission belt at the upper track groove in the groove group, that is, the output end of the power component 2 meshes with the corresponding transmission gear.

[0046] One set of grooves corresponds to one curtain, and two sets of grooves correspond to the left and right curtains respectively;

[0047] Taking the left curtain as an example, each of the two drive belts in this set of grooves is fixedly connected to a pulley, and the two pulleys are fixedly connected to the left end and the right end of the left curtain, respectively.

[0048] By driving the movement of the power component 2 through the drive component 3, the power output position is switched, that is, the power is switched to either of the two transmission belts in the same slot group, so that the left end of the left curtain can become the active end to drive the left curtain to move, or the right end of the left curtain can become the active end to drive the left curtain to move.
