Description

Technical fields:

[0001] This utility model relates to a transmission box for a multi-curtain system. Background technology:

[0002] Existing multi-curtain systems, such as those that simultaneously function as day curtains and night curtains, control the day curtains and night curtains using two separate motors that are structurally and spatially independent. Correspondingly, each motor requires its own independent drive unit, meaning one motor is matched to one drive unit. This lack of drive unit integration prevents the simultaneous matching of two power sources in a single drive unit application scenario. Summary of the Invention:

[0003] To overcome the problem that existing transmission boxes have low integration and cannot simultaneously match dual power applications, this utility model provides a transmission box for multi-curtain systems.

[0004] A transmission box for a multi-curtain system includes a front housing and a rear housing that cooperate with each other. The front end face of the front housing has an upper connecting hole and a lower connecting hole. The rear housing has a first transmission groove and a second transmission groove. A second transmission member is provided between the upper connecting hole and the second transmission groove in the front housing and the rear housing, and a first transmission member is provided between the lower connecting hole and the first transmission groove. The axis of the first transmission member and the axis of the second transmission member are offset vertically and parallel to each other. The first power is input from the lower connecting hole and transmitted to the first transmission member and then output from the first transmission groove to drive the first curtain. The second power is input from the upper connecting hole and transmitted to the second transmission member and then output from the second transmission groove to drive the second curtain.

[0005] The transmission box of the multi-curtain system of this utility model embodiment has a first transmission component and a second transmission component that are respectively matched with the first power and the second power. It can realize the application scenario of simultaneously matching dual power in one transmission box. It has a simple structure, small size, and is convenient, quick and efficient to install.
