[0002] Electric curtains are devices that electrically control the opening and closing of curtains. Users can use a remote control to conveniently open and close the curtains, which is more interesting than manual curtains. However, consumers may not be able to accurately measure the width of windows, so retractable electric curtain tracks have appeared on the market. Traditional electric curtain tracks with retractable functions are connected by two electric slide rails. Separate motors and toothed belts are provided on the two electric slide rails. The sliding hooks are fixed on the toothed belts, and the sliding hooks are driven by the motor to move along the toothed belts, while the tops of the curtains on the left and right sides are fixed on the sliding hooks. The function of opening and closing the curtains is completed through this structure. However, traditional electric curtain tracks with retractable functions require two motors to control the opening and closing of the curtains, which has a high manufacturing cost and cannot be applied to windows with single-piece curtains. It does not really change the movable range of the sliding hooks. In order to address the deficiencies of the prior art, we propose an electric curtain track with retractable functions.

[0022] The telescopic assembly 3 includes a bracket 31, which is fixedly mounted on the left inner wall of the slide rail 2, and a rotating shaft 32 is rotatably connected to the outer surface of one side of the bracket 31. The outer wall of the rotating shaft 32 is fixedly connected to a spring 33, and one end of the spring 33 away from the rotating shaft 32 is fixedly connected to the bracket 31.

The right inner wall of the slide rail 1 is fixedly connected to the bracket 25, and the inner wall of the slide rail 1 is fixedly connected to the inner wall of the slide rail 1. A motor 36 is fixedly installed, and the rotating shaft of the motor 36 is fixedly connected to a threaded rod 37, and the outer wall of the threaded rod 37 is rotatably connected to a rotating tube 38. One end of a pull rope 34 away from the rotating shaft 32 is fixedly connected to the rotating tube 38, one side of the pull rope 34 is wound around the outer wall of the rotating shaft 32, and the other side of the pull rope 34 is wound around the outer wall of the rotating tube 38. The outer wall of the threaded rod 37 is threadedly connected to a retaining ring 39 located on one side of the rotating tube 38, and a sliding hook 311 is provided on the pull rope 34.

[0023] There are two rotating shafts 32 and two winding springs 33, which are symmetrically distributed on both sides of the bracket 31. There are two rotating tubes 38 and two clamping rings 39, which are symmetrically distributed on both sides of the bracket 35. The winding directions of the two rotating shafts 32 and the pull ropes 34 on the rotating tubes 38 are opposite.

[0024] By rotating the rotating tube 38, the pull rope 34 can be further wrapped around the outer wall of the rotating tube 38 or released. When the pull rope 34 is further wrapped around the outer wall of the rotating tube 38, the sliding hook 311 moves along the pull rope 34 toward the side of the rotating tube 38. When the pull rope 34 is released, the clockwork spring 33 drives the rotating shaft 32 to rotate and wraps the pull rope 34 around the outer wall of the pull rope 34. At this time, the sliding hook 311 moves along the pull rope 34 toward the side of the rotating shaft 32.

[0025] The clamping ring 39 can clamp the rotating tube 38 to the outer wall of the threaded rod 37, so as to fix the rotating tube 38 to the outer wall of the threaded rod 37 after adjusting the length of the pull rope 34;

[0026] By loosening the retaining ring 39 and rotating the rotating tube 38, the length of the pull rope 34 can be adjusted according to the relative positions of the slide rail 1 and the slide rail 2 2. Then, the retaining ring 39 is tightened along the thread to fix the rotating tube 38 on the outer wall of the threaded rod 37. At this time, the rotating tube 38 will rotate together with the threaded rod 37.

[0027] The lifting assembly 4 includes a slide rail 3 41, a slider 42 is slidably connected to the inner wall of the slide rail 3 41, a fixed pulley 43 is fixedly connected to the top of the slide rail 3 41, a pull rope 2 44 is fixedly connected to the top of the slider 42, a motor 2 45 is arranged on one side of the slide rail 3 41, a rotating shaft of the motor 2 45 is fixedly connected to a rotating shaft 2 46, an end of the pull rope 2 44 away from the slider 42 is fixedly connected to the rotating shaft 2 46, and the pull rope 2 44 is wound around the outer wall of the rotating shaft 2 46;

[0028] By driving the rotating shaft 46 to rotate through the motor 45, the pull rope 44 can be further wrapped around the outer wall of the rotating shaft 46 or released. When the pull rope 44 is further wrapped around the outer wall of the rotating shaft 46, the slider 42 is pulled upward. When the pull rope 44 is released, the slider 42 will slide downward due to gravity.

[0029] The outer wall of the fixed pulley 43 is fitted with the second pull rope 44, so that the end of the second pull rope 44 close to the slider 42 is parallel to the vertical direction;

[0030] By making one end of the second pull rope 44 close to the slider 42 parallel to the vertical direction, the second pull rope 44 can work in the best force direction.

[0031] Among them, there are two slide rails 3 41, sliders 42, fixed pulleys 43 and pull ropes 2 44, which are symmetrically distributed on the left and right sides of motor 2 45. The two sliders 42 are fixedly connected to slide rail 1 1 and slide rail 2 2 respectively. Motor 2 45 and two slide rails 3 41 are fixedly installed on the wall.

[0032] The sliders 42 symmetrically distributed on the left and right sides of the motor 2 45 can drive the slide rail 1 1 and the slide rail 2 2 to rise and fall synchronously, thereby adjusting the height of the curtain slide rails.

[0033] The working process of the utility model is as follows:

[0034] First, adjust the relative positions of the slide rail 1 and the slide rail 2 according to the width of the window, rotate the rotating tube 38, adjust the length of the pull rope 1 34, then tighten the clamping ring 39 along the thread to fix the rotating tube 38 to the outer wall of the threaded rod 37. At this time, the rotating tube 38 will rotate together with the threaded rod 37. At this time, start the motor 1 36 to drive the rotating tube 38 to rotate through the threaded rod 37. When the pull rope 1 34 is further wrapped around the outer wall of the rotating tube 38, the sliding hook 311 moves along the pull rope 1 34 to one side of the rotating tube 38. When the pull rope 1 34 is released, the clockwork spring 33 drives the rotating shaft 1 32 to rotate, and the pull rope 1 34 is wrapped around the pull rope 1 3 4 outer wall, at this time, the sliding hook 311 moves along the pull rope 1 34 to the side of the rotating shaft 1 32. If only one curtain needs to be installed, the sliding hook 311 is only installed on one of the pull ropes 1 34, and the motor 2 45 is started. The motor 2 45 drives the rotating shaft 2 46 to rotate, and the pull rope 2 44 is further wound around the outer wall of the rotating shaft 2 46 or released. When the pull rope 2 44 is further wound around the outer wall of the rotating shaft 2 46, the slider 42 is pulled up. When the pull rope 2 44 is released, the slider 42 will slide downward due to gravity. The sliders 42 symmetrically distributed on the left and right sides of the motor 2 45 are synchronously raised and lowered, thereby adjusting the height of the curtain slide rail.
