[0002] Traditional manual Venetian blinds and honeycomb blinds include an upper track with a transmission rod and a rope winder installed in the upper track. The transmission rod is driven by a structure such as a bead or a spring to rotate the rope winder to wind up and release the rope to drive the curtain body to open and close. With the development of intelligent curtains, traditional manual curtains are developing towards electric curtains. In order to reduce costs, the upper track is not re-molded and the existing upper track is used. A one-way output drive device can be installed at the end of the upper track to replace the manual drive device such as a bead or a spring, and a power supply device is installed at the other end. For the replaced electric curtain, since the two ends of the upper track are respectively equipped with a one-way output drive device and a power supply device, the length of the upper track is not convenient to cut. , it is difficult to meet the needs of some users who need to modify the size of the curtains. In order to avoid the above problems, a two-way output drive device is installed in the middle position of the upper track, which can simultaneously drive the rope winders on both sides, so that the two ends of the upper track can be conveniently cut. However, this structure is large in size, high in cost, and too long in size. In addition, the power supply part is difficult to be built in and needs to be hung outside the upper track.

[0026] like Figure 1-5 As shown, the utility model provides an improved electric curtain, including an upper track 1, a one-way driving device 2 is provided in the middle of the upper track 1, an output shaft 2.1 of the one-way driving device 2 is connected to a transmission rod 4 through a transmission assembly 3, and the transmission assembly 3 transmits the power of the output shaft 2.1 in parallel to the transmission rod 4, the transmission rod 4 is arranged parallel to the output shaft 2.1 and is located on both sides of the center line of the upper track 1, and two symmetrically arranged rope winders 5 are provided on the transmission rod 4, and the rope winders 5 are connected to a curtain body 7 through a pull rope 6. The center line of the upper track 1 refers to the center line along the length direction of the upper track 1, and the curtain body 7 can be a venetian blind curtain body, a honeycomb curtain body, a pleated curtain body, etc., which are connected up and down by pull ropes and opened and closed by pulling up and down by the pull ropes. The utility model is preferably described by taking a venetian blind curtain body as an example, and the venetian blind curtain body is composed of a plurality of blinds.

[0027] The utility model adopts a one-way drive device 2 whose output shaft 2.1 is arranged in parallel with the transmission rod 4 in the upper track 1, and is eccentrically arranged on both sides of the center line of the upper track 1, so as to make full use of the installation space, and transmit power in parallel through the transmission component 3, so that the power of the one-way drive device 2 is transmitted in parallel to the transmission rod 4 to realize the synchronous retraction and release of the pull rope 6 by the rope reels 5 on both sides. The one-way drive device 2 is small in size and low in cost, and can match the existing upper track 1, so that the traditional manual curtains are seamlessly connected to the electric curtains. In addition, the one-way drive device 2 is installed in the middle of the upper track 1, and does not occupy the cutting space at both ends of the upper track 1, so that people can adjust the length of the upper track 1 conveniently.

[0028] Among them, see Figure 2 , 4 The transmission assembly 3 includes a first gear 3.1 and a second gear 3.2. The first gear 3.1 is coaxially transmitted with the output shaft 2.1, and the second gear 3.2 is coaxially transmitted with the transmission rod 4. The first gear 3.1 and the second gear 3.2 are parallelly meshed for transmission. The output shaft 2.1 of the one-way drive device 2 outputs power and drives the first gear 3.1 to rotate coaxially. The first gear 3.1 drives the second gear 3.2 to rotate, and the second gear 3.2 drives the transmission rod 4 to rotate coaxially. Through the action of the first gear 3.1 and the second gear 3.2, the power of the output shaft 2.1 is transmitted in parallel. By providing a transmission rod 4, the one-way driving device 2 can be installed in the middle of the upper track 1 to drive the driving rod 4 to synchronously control the rope winders 5 on both sides, so that the one-way driving device 2 is not limited to being installed only at the end of the upper track 1, but can also realize the function of driving both ends of the two-way driving device, and the cost is lower and the size is small. While ensuring that the traditional manual blinds can be seamlessly converted into electric blinds, the ends of the upper track 1 can also be cut and adjusted to size. Because the one-way driving device 2 is installed in the middle of the upper track 1, the two ends of the upper track 1 can be left empty, which is convenient for cutting and flexible to use.

[0029] Among them, see Figure 2 , 5 The rope reel 5 includes a rope reel seat 5.1, in which a winding core mounting position 5.2 is provided on the coaxial side of the transmission rod 4 and offset from the center line of the upper track 1. A winding core 5.3 for winding and releasing the pull rope 6 is provided on the winding core mounting position 5.2. Since the one-way drive device 2 and the transmission rod 4 are both eccentrically mounted, in order to adapt to the coaxial transmission of the winding core 5.3 and the transmission rod 4, the winding core mounting position 5.2 in the rope reel 5 is eccentrically set to facilitate the transmission rod 4 to rotate the winding core 5.3.

[0030] Among them, see Figure 5The two ends of the winding core 5.3 are respectively provided with a first rotating part 5.4 and a second rotating part 5.5, and the two ends of the winding core installation position 5.2 are respectively provided with a first supporting part 5.6 and a second supporting part 5.7 that cooperate with the first rotating part 5.4 and the second rotating part 5.5. A rope running hole 5.8 for passing the pull rope 6 is provided on the rope winding device seat 5.1 near the first supporting part 5.6 and located at the center line of the upper track 1. In order to save installation space and facilitate the installation of the one-way drive device 2 in the middle of the upper track 1, the positions of the transmission rod 4 and the winding core 5.3 are eccentrically set, and the venetian blind body below the upper track 1 is still normally set directly below the upper track 1, so the rope running hole 5.8 is still kept in the center to ensure that the venetian blind body can be stably opened and closed up and down under the action of the pull rope 6.

[0031] Among them, see Figure 5 In order to adapt to the dimming of the blinds, a reversing wheel 5.9 is provided on the winding core 5.3 near the first rotating part 5.4, and a rope ladder 8 is connected to the reversing wheel 5.9, which is connected to each blind blade. The reversing wheel 5.9 can play a role in reversing and dimming.

[0032] Among them, see Figure 4 The one-way driving device 2 is provided with a motor movement 2.2, a reducer 2.3, a control board 2.4 and a power supply unit 2.5. The motor movement 2.2 and the power supply unit 2.5 are electrically connected to the control board 2.4. Since the one-way driving device 2 is eccentrically arranged, there is more installation space, and the power supply unit 2.5 can be built-in, the overall structure is neater and more beautiful, and the power supply unit 2.5 is prevented from being exposed outside the upper track 1.

[0033] Among them, see Figure 2 The length of the transmission rod 4 is less than the length of the upper track 1, and the distances from the two ends of the transmission rod 4 to the corresponding ends of the upper track 1 are greater than zero. This structural setting facilitates cutting space at both ends of the upper track 1, and the transmission rod 4 will not be cut during cutting, which can not only ensure the normal transmission of the transmission rod 4, but also facilitate the cutting and adjustment of the size of the upper track 1.

[0034] Among them, see Figure 2 , 3 4. An installation auxiliary part 2.6 is provided on one end of the one-way drive device 2 relative to the output shaft 2.1. Since the one-way drive device 2 is eccentrically installed in the upper track 1, one side of the one-way drive device 2 is in contact with the inner wall of one side of the upper track 1, and the distance from the other side to the other inner wall of the upper track 1 is greater than zero. In order to prevent the one-way drive device 2 from radial movement, radial limiters are respectively provided at both ends of the one-way drive device 2. One end is filled and limited by the outer shell of the transmission assembly 3, and the other end is filled and limited by providing the installation auxiliary part 2.6, so that the one-way drive device 2 can be stably installed in the upper track 1.

[0035] When in use, the one-way drive device 2 works and outputs power through the output shaft 2.1. The output shaft 2.1 transmits the first gear 3.1, the second gear 3.2, the transmission rod 4, and the rope reel 5 to reel in and release the pull rope 6, thereby controlling the opening and closing of the blind body. The output shaft 2.1 of the one-way drive device 2 is arranged in parallel with the transmission rod 4 in the upper track 1, and is eccentrically arranged on both sides of the center line of the upper track 1, making full use of the installation space, and transmitting power in parallel through the transmission assembly 3, and transmitting the power of the one-way drive device 2 in parallel to the transmission rod 4 to realize the synchronous retraction and release of the pull rope 6 by the rope reels 5 on both sides, so that the traditional manual curtains are seamlessly connected to electric curtains, and the one-way drive device 2 is installed in the middle of the upper track 1, and the two ends of the transmission rod 4 do not hit the two ends of the upper track 1, so that there is cutting space at both ends of the upper track 1, which is convenient for adjusting the size. In addition, the eccentric setting of the one-way drive device 2 can have more installation space, and the power supply unit 2.5 can be built-in, and the overall structure is more beautiful and neat.
