[0002] Electric curtains are used to electrically control the opening and closing of curtains. They are suitable for windows of different lengths and heights, including curved windows. In high-ceilinged buildings or villas, where the required curtain height is greater, electric curtains are more suitable. However, the curtains are installed at a high position, making them difficult to install and remove. In existing technology, a lifting device is installed inside the curtain box to raise and lower the curtain track. However, the lifting device is always located inside the curtain box, and the power transmission part of the lifting device is separate from the transmission box of the curtain track, requiring a separate power source.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0018] Reference Figures 1 to 7 As shown, the power box structure of a lifting curtain in this embodiment includes a housing 1 and a transmission box 2. The bottom of the housing 1 is formed in a transmission groove 11. At least part of the transmission box 2 is detachably connected to the transmission groove 11. The transmission box 2 is connected to the curtain track. The housing 1 has a first transmission hole 12 and a second transmission hole 13. The first transmission hole 12 is located above the curtain track, and the second transmission hole 13 communicates with the transmission box 2. The central axis of the first transmission hole 12 and the central axis of the second transmission hole 13 are perpendicular. By combining the housing 1 and the transmission box 2, power can be transmitted through the first transmission hole 12. This power can be input into the lifting device. The lifting device is set on the curtain track. When the curtain track is raised and lowered, the entire housing 1 and the transmission box 2 are raised and lowered synchronously, which facilitates the maintenance of the structure inside the housing 1 and the transmission box 2. Power can be transmitted to the transmission box 2 through the second transmission hole 13, thereby realizing the opening and closing of the curtain. The transmission box 2 and the lifting device can share a power source.
[0019] Reference Figure 1 As shown, the housing 1 includes an outer shell 14 and an inner shell 15. The inner shell 15 is detachably connected to the outer shell 14. The outer shell 14 and the inner shell 15 can be connected by a snap-fit or by screws. Preferably, in this embodiment, the two are detachably connected by screws. A transmission cavity 151 is formed on the inner shell 15. The transmission cavity 151 is connected to the second transmission hole 13. A transmission structure is set in the transmission box 2. Power can be transmitted to the transmission box 2 through the transmission structure, thereby driving the belt in the track to move and realize the opening and closing of the curtain.
[0020] Reference Figure 2 and Figure 7 As shown, the inner shell 15 includes a power section 152, and a power cavity 153 is formed in the power section 152. The power cavity 153 is connected to the transmission cavity 151. The power cavity 153 is used to install a reduction mechanism or a combination of a reduction mechanism and a clutch mechanism. The clutch mechanism is a clutch structure with magnetic beads in an electric opening and closing curtain, and the reduction mechanism is a planetary gear reduction set. The motor, the reduction mechanism, and the clutch mechanism are connected in sequence.
[0021] The central axis of the power chamber 153 coincides with the central axis of the first transmission hole 12, ensuring their concentricity.
[0022] Reference Figure 2 , Figure 3 and Figure 7 As shown, multiple limiting strips 141 are integrally formed on the inner wall of the outer shell 14, and limiting grooves 154 corresponding to the limiting strips 141 are formed on the inner shell 15. The limiting strips 141 are inserted into the corresponding limiting grooves 154. Preferably, there are four limiting strips 141, with two limiting strips 141 as a group, respectively set on opposite sides of the inner wall of the outer shell 14. Multiple protrusions are integrally formed on the outer wall of the inner shell 15, with two protrusions as a group. The limiting grooves 154 are formed between the two protrusions in the same group. The limiting strips 141 and the limiting grooves 154 cooperate to form a limiting between the inner shell 15 and the outer shell 14. The bottom of the outer shell 14 and the bottom of the inner shell 15 are also connected by screws. Preferably, multiple mounting holes are provided on the transmission groove 11, and multiple connection holes corresponding to the mounting holes are formed on the inner shell 15. Screws are installed between the mounting holes and the corresponding connection holes. Setting the mounting holes at the transmission groove 11 can also hide the screws.
[0023] Reference Figure 2 As shown, a space 3 is formed between the power section 152 and the housing 14, providing a mounting space for the brushless motor.
[0024] Reference Figure 4 and Figure 5 As shown, the inner wall of the transmission groove 11 is provided with multiple slots 111, and multiple locking strips 21 are formed on the transmission box 2. The locking strips 21 are inserted into the corresponding slots 111. Through the cooperation of the slots 111, a positioning is formed between the transmission box 2 and the outer shell 14.
[0025] Reference Figure 4 and Figure 5 As shown, countersunk holes 16 are provided on both opposite sides of the housing 1. The countersunk holes 16 can hide the ends of the screws. Threaded holes 22 corresponding to the countersunk holes 16 are provided on both opposite sides of the transmission box 2. Preferably, there are two countersunk holes 16. After the bolt passes through the countersunk holes 16, it is threaded into the corresponding threaded holes 22, thereby realizing the fixed connection between the housing 14 and the transmission box 2.
[0026] At least part of the track is located within the transmission groove 11. The length of the transmission box 2 is not limited. The length of the transmission box 2 can cover the entire length of the transmission groove 11. The transmission box 2 can also extend out of the transmission groove 11. Of course, the length of the transmission box 2 can be shorter than the length of the transmission groove 11. When the length of the transmission box 2 is shorter than the length of the transmission groove 11, after the track is connected to the transmission box 2, apart from the part of the track located inside the transmission box 2, a part of the track is still located at the transmission groove 11, and then extends out of the transmission groove 11. When the length of the transmission box 2 is the same as the length of the transmission groove 11, except for the part of the track located inside the transmission box 2, the rest of the track is located outside the transmission groove 11.
