[0022] 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.

[0023] Reference Figures 1 to 5 As shown, a screen curtain in this embodiment includes a screen curtain assembly 1 and a power assembly 2. The screen curtain assembly 1 includes a screen track 11 and a plurality of screen brackets 12. The power assembly 2 includes a power track 21 and at least one power bracket 22. The screen track 11 and the power track 21 are connected in parallel to each other. The power bracket 22 is connected to the corresponding screen bracket 12, so that when the power bracket 22 moves, it can drive the screen bracket 12 connected to it to move in the same direction.

[0024] When there is only one power support 22, the power support 22 can move from one end of the power track 21 to the other end to realize the one-way opening and closing of the screen;

[0025] When there are two power supports 22, the two power supports 22 move relative to each other or away from each other, thereby realizing the opening and closing of the screen in opposite directions.

[0026] Among them, the power track 21 can be a conventional curtain track, using the same transmission components as the curtain track. The transmission components include housings located at both ends of the curtain track, and a curtain motor connected to one of the housings. Thus, it is only necessary to close both ends of the screen track 11, without the need for additional design of the transmission housings at both ends of the screen track 11, or the need for additional design of the space required to accommodate the synchronous belt in one of the track grooves, saving design and mold costs.

[0027] Reference Figure 1 , Figure 2 and Figure 4 As shown, multiple connecting brackets 3 connect the screen bracket 12 and the power bracket 22 to facilitate the connection between the screen bracket 12 and the power bracket 22, and to the curtain box through the connecting brackets 3;

[0028] The screen bracket 12 and the power bracket 22 can be connected by horizontal or vertical insertion, or by snap-fit.

[0029] In this embodiment, two connecting frames 3 are provided, which are located at the two ends of the screen bracket 12 and the power bracket 22, respectively, thereby increasing the connection stability between the screen bracket 12 and the power bracket 22.

[0030] Reference Figure 4 As shown, the connecting frame 3 has a first slot 31 and a second slot 32. The screen track 11 is inserted into the first slot 31, and the power track 21 is inserted into the second slot 32. The connecting frame 3 supports the screen track 11 and the power track 21 through the first slot 31 and the second slot 32.

[0031] The first slot 31 limits the vertical movement of the screen track 11, and the second slot 32 limits the vertical movement of the power track 21.

[0032] Preferably, the connecting frame 3 has positioning holes 34 at the first slot 31 and the second slot 32. Screws are connected at the positioning holes 34. The screws act as abutments against the power rail 21 or the screen rail 11, so that the screen rail 11 and the power rail 21 are subjected to a downward pressure. This can further limit the vertical movement of the screen rail 11 and the power rail 21 and prevent them from loosening.

[0033] Reference Figure 4 As shown, both ends of the connecting frame 3 are provided with fixing ears 33, and multiple fixing holes 331 are provided on the fixing ears 33. The two fixing ears 33 are at the same height, and the connecting frame 3 is detachably connected to the curtain box through the fixing ears 33.

[0034] Each fixing ear 33 has two fixing holes 331, which are connected to the curtain box by screws.

[0035] In one embodiment, two power supports 22 are arranged opposite each other, and the two power supports 22 move in opposite directions. The two power supports 22 move relative to each other or away from each other, thereby realizing the opening and closing of the screen in opposite directions.

[0036] Reference Figure 3 and Figure 5 As shown, a limiting component 23 is detachably connected to the power bracket 22. The power bracket 22 and the limiting component 23 are detachably connected by bolts and nuts. Specifically, there are two bolts and two nuts.

[0037] The limiting member 23 forms a limiting groove 231 on the side facing the corresponding screen bracket 12. The limiting groove 231 is a through groove. The end of the screen bracket 12 is inserted into the limiting groove 231, so that when the power bracket 22 moves, the screen bracket 12 can be moved by the limiting member 23.

[0038] The end of the screen bracket 12 is detachably connected to a clip 24, which extends into the limiting groove 231. The clip 24 changes the structure of the end of the screen bracket 12 so that the end of the screen bracket 12 can be inserted into the limiting groove 231.

[0039] Furthermore, the clip 24 is connected to the screen bracket 12 by bolts, without directly changing the structural design of the screen bracket 12.

[0040] The power assembly 2 includes transmission boxes (not shown in the figure) located at both ends of the power track 21. One of the transmission boxes is connected to a motor. Of the two transmission boxes, one is the main transmission box and the other is the auxiliary transmission box. The motor is connected to the main transmission box.

[0041] The transmission box contains a rotating gear, and a synchronous belt connects the two gears. The synchronous belt is detachably connected to the power support 22. The output end of the motor is connected to one of the gears. The transmission box is detachably connected to the power rail 21. The gear and the transmission box can be rotatably connected via bearings.
