A second outer motor cover is installed at one end of the second outer tube 12, and a second motor is installed on the second outer motor cover. The second motor is located inside the second outer tube 12. At the same time, a second V-shaped shaft 14 is installed on the second output shaft of the second motor. The second motor drives the second V-shaped shaft 14 to rotate through the output shaft of the second motor.
Two second brackets 13 are provided with a second outer battery tube 15. A second lithium battery is installed in the second outer battery tube 15. The second lithium battery is electrically connected to the second motor, and the second lithium battery supplies power to the second motor. At the same time, a third end cap and a four end cap are installed in the second outer battery tube 15, and the third end cap and the fourth end cap are used to axially fix the second lithium battery, reducing the possibility of the second lithium battery moving inside the outer battery tube 15.
In this embodiment, there is a second lifting component in the shell 2. The second lifting component includes a second cord reel 16, the second cord reel 16 is set on the V-shaped shaft 14, and the second cord reel 16 is driven to rotate through the rotation of the second V-shaped shaft 14. There are two second cord reels which are provided with a second lifting rope 17. The second lifting rope 17 is reeled or released on the second cord reel 16 through the rotation of the second cord reel 16. Two second rope holes are symmetrically defined in the shell 2, and the two lifting ropes 17 pass through the two second rope holes.
In this embodiment, two translucent shade fabrics 11 are provided on the two second lifting ropes 17. By reeling or releasing the second lifting ropes 17, the translucent fabrics 11 are opened or folded. Users can selectively use the translucent fabrics 11 according to actual situations. Moreover, the two first lifting ropes 9 can pass through the translucent fabric 11.
In this embodiment, the middle beams 10 are provided on the two first lifting ropes 9. The middle beams 10 are positioned below the translucent fabric 11.

An angular velocity sensor 21 is mounted on a bottom of the bottom beam 1. The angular velocity sensor 21 is electrically connected to the first motor 5. The angular velocity sensor 21 detects if there are any obstacles during the movement of the translucent fabric 11. If one obstacle is detected, the angular velocity sensor 21 sends a signal to the first motor 5, causing the first motor 5 to rotate in reverse. As a result, the blackout fabric 3 moves in an opposite direction for a short distance, serving as a protective measure for the blackout fabric 3.
