DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0019] Example 1

[0020] A curtain booster device, such as Figure 1 , Figure 2 and Figure 4 As shown, it includes an installation frame 1, a connecting member 3 is slidably connected inside the installation frame 1, a driving component 2 is rotatably connected to the connecting member 3, the driving component 2 includes a motor and a roller, the motor output shaft is connected to the roller, the motor output shaft is rotatably connected to the connecting member 3, the front and rear interiors of the installation frame 1 are connected to a first guide member 4 for limiting and guiding the connecting member 3, the first guide member 4 is in contact with the connecting member 3, a lifting knob 5 is threadedly connected to the installation frame 1, the lifting knob 5 is provided with a card groove for increasing the friction of the hand, and the lifting knob 5 is rotatably connected to the connecting member 3.

[0021] like Figure 1 , Figure 2 and Figure 5 As shown, it also includes a walking wheel 6, a left-right symmetrical walking wheel 6 is rotatably connected inside the installation frame 1, a left-right symmetrical second guide member 8 is slidably connected inside the installation frame 1, a first spring 7 is connected between the second guide member 8 and the installation frame 1, a contact plate 9 is connected to the walking wheel 6, the contact plate 9 is connected to the adjacent second guide member 8, buttons 10 are slidably connected to the left and right sides of the installation frame 1, the button 10 is an arc-shaped structure that fits the hand, a second spring 11 is connected between the button 10 and the installation frame 1, an extension plate 12 is connected to the button 10, a third spring 13 is connected inside the extension plate 12, and the extension plate 12 is contact-connected to the contact plate 9.

[0022] Curtains are decorative objects made of cloth or other materials used to cover windows, and are used to adjust indoor light, protect privacy, and decorate rooms. With the development of technology, electric curtains are used more and more widely. Electric curtains are opened and closed by electric drives or motors. Compared with traditional curtains operated by manual pull cords or pull rods, electric curtains have more intelligent and convenient advantages. The curtain boost function is based on the function of electric curtains realized by automation technology or intelligent equipment, which is used to help the movement of curtains when opening and closing. The device is installed on the curtain track. When the width of the curtain track is 6 When the width is appropriate, the device is connected to the curtain track through the running wheel 6, and then the lifting knob 5 is rotated to make the driving assembly 2 move upward. The first guide member 4 limits the upward movement of the driving assembly 2 and prevents the driving assembly 2 from deflecting. When the roller contacts the curtain track, the motor is turned on, and the motor output shaft drives the roller to move, and at the same time drives the running wheel 6 to move in the same direction, thereby completing the opening and closing of the curtain. When the width of the curtain track is narrow and it is inconvenient to directly connect the running wheel 6 to the inside of the curtain track, the buttons 10 on both sides are pressed inward, and the adjacent second springs 11 are compressed, so that the adjacent extension plates 12 moves inwards. In the initial state, the adjacent third spring 13 is compressed, the contact plate 9 contacts the adjacent extension plate 12, and the adjacent extension plate 12 moves inwards continuously, driving the adjacent contact plate 9 to rotate. When the contact plate 9 rotates to a certain angle, the adjacent third spring 13 is reset, so that the extension block on the extension plate 12 slides outwards with the extension rod, thereby driving the adjacent second guide member 8 to slide, and the adjacent first spring 7 is compressed, thereby completing the rotation of the adjacent walking wheel 6. When the adjacent button 10 slides to the limit position, the adjacent walking wheel 6 rotates 90°. At this time, the walking wheel 6 The wheel 6 is in the same direction as the curtain track, and then the walking wheel 6 is placed in the curtain track, and then the button 10 is released, the first spring 7 and the second spring 11 are reset, and at the same time, the contact plate 9 squeezes the extension block on the adjacent extension plate 12 to shrink under force, and the third spring 13 is compressed to the initial state, and the contact plate 9 drives the walking wheel 6 to reset, thereby clamping the walking wheel 6 in the curtain track. The left and right walking wheels 6 play the role of auxiliary rollers to drive the device to move, and at the same time play the role of limiting support for the device, thereby enhancing the convenience, comfort and intelligence of the electric curtains, and providing better user experience and life convenience.

[0023] Example 2

[0024] On the basis of Example 1, Figure 1-Figure 3 As shown, it also includes an anti-collision member 15, the left and right parts of the installation frame 1 are slidably connected with the anti-collision member 15, the anti-collision member 15 is connected with a limiting plate, a fourth spring 14 is connected between the anti-collision member 15 and the installation frame 1, and the lower part of the installation frame 1 is connected with two hanging rings 16 for hanging curtains.

[0025] When the device is at the extreme position of the curtain track, the wall or the curtain track will squeeze the anti-collision member 15, and the fourth spring 14 will be compressed. Under the action of the fourth spring 14, the squeezing of the device by the curtain track is buffered, thereby making the device more stable.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
