Description

Technical Field

[0001] This utility model relates to the field of automatic curtain technology, and in particular to a driving device for automatic curtains. Background Technology

[0002] Curtains are curtains made of materials such as cloth, linen, gauze, aluminum slats, wood slats, and metal. They serve to block sunlight, insulate against heat, and regulate indoor light, while also beautifying the environment and decorating the home. They are typically hung on windows and can be opened and closed manually or electrically, making them an indispensable part of modern home life. Curtains come in many varieties, and can be categorized into several types based on factors such as material, style, and function, such as blackout curtains, Venetian blinds, roller blinds, and Roman blinds. They not only possess practicality but also embody aesthetic value, reflecting the homeowner's taste and home style.

[0003] Automatic curtains, also known as smart curtains or motorized curtains, are different from traditional manual curtains. They can be remotely operated via remote control, mobile app, or voice control, eliminating the need to physically pull the curtains at the window. Automatic curtains also feature timer functions, light sensors, and temperature sensors, automatically opening or closing based on preset times, light intensity, or indoor temperature. However, automatic curtains often require the use of curtain tracks to open and close properly. This not only increases household costs for users who already have motorized curtains but whose renovations are complete, but also requires disassembling and reinstalling the existing curtain tracks, resulting in waste. Summary of the Invention

[0004] The purpose of this invention is to provide a driving device for automatic curtains to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic curtain drive device includes: a drive body, a groove on the drive body, slidable mounting plates symmetrically arranged in the groove, and a plurality of rollers on the mounting plates.

[0007] Preferably, the driver body is provided with a controller, which controls the operation of the components on the driver body.

[0008] Preferably, a reciprocating lead screw is rotatably disposed within the groove, and the reciprocating lead screw is electrically connected to the controller.

[0009] Preferably, a limit rod is symmetrically fixedly arranged in the groove. The limit rod and the reciprocating screw both pass through the mounting plate. The mounting plate is slidably connected to the limit rod and threadedly connected to the reciprocating screw.

[0010] Preferably, the mounting plate has symmetrically formed grooves, and a fixing rod is slidably connected in one of the grooves of the mounting plate.

[0011] Preferably, a rotating shaft is fixedly connected to one end of the fixed rod away from the slide groove, and a rotating rod is rotatably connected to the rotating shaft.

[0012] Preferably, a fixing rod two is slidably connected within the groove of another mounting plate.

[0013] Preferably, the second fixing rod has a through groove.

[0014] Preferably, the dimensions of the through groove are adapted to the rotating rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The movable mounting plate design allows the drive unit to adapt to curtain tracks of different sizes and shapes. Users can easily attach the drive unit to the curtain track, or remove and move it as needed. The installed drive unit, along with adjustable rollers, hangs on the track. When the drive unit moves, it moves the curtains synchronously. As the mounting plate moves, it causes the rollers to clamp the curtain track, allowing the rollers to move along the track. By controlling the rotation direction of the reciprocating screw, precise control of the tension between different sized tracks can be achieved.

[0017] While the rollers on the mounting plate are hung on the guide rail by the reciprocating screw driving the rollers, the rotating rod perpendicular to the first fixed rod moves in the opposite direction to the second fixed rod. This causes the end of the rotating rod to pass into the through groove, which puts the curtain rings on and prevents them from coming off. This allows the curtains to be opened or closed more effectively, improving the stability of the curtains during the opening or closing process. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0025] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0026] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0027] Please see Figures 1-4 An automatic curtain drive device includes: a drive body 1, with a groove 101 on the drive body 1, and symmetrically arranged sliding mounting plates 202 within the groove 101. Several rollers 203 are mounted on the mounting plates 202. The movable mounting plates 202 allow the drive body 1 to adapt to curtain tracks of different sizes and shapes. Users can easily attach the drive body 1 to the curtain track, or remove and move it as needed. By mounting the drive body 1 on the track with the adjustable rollers 203, the movement of the drive body 1 can drive the curtain to move synchronously.

[0028] The drive unit 1 contains a controller that controls the operation of the components on the drive unit 1. The controller sends commands to the reciprocating screw 2 on the drive unit 1, causing the reciprocating screw 2 to start rotating. When it is necessary to open or close the curtains, the controller sends commands to the motor controlling the roller 203, causing the roller 203 to start rotating, thereby opening or closing the curtains.

[0029] Furthermore, a reciprocating screw 2 is rotatably mounted within the groove 101, and the reciprocating screw 2 is electrically connected to the controller. A limit rod 201 is also symmetrically fixed within the groove 101. Both the limit rod 201 and the reciprocating screw 2 pass through the mounting plate 202. The mounting plate 202 is slidably connected to the limit rod 201 and threadedly connected to the reciprocating screw 2. The reciprocating screw 2 is electrically connected to the controller. When the controller receives an external command, it sends a signal to the reciprocating screw 2, causing it to begin rotating. Because the mounting plate 202 is threadedly connected to the reciprocating screw 2, the rotation of the screw is converted into linear movement of the mounting plate 202. As the mounting plate 202 moves, it drives the roller 203 to clamp the curtain rail, allowing the roller 203 to move along the curtain rail. By controlling the rotation direction of the reciprocating screw 2, precise control of the tension between rails of different sizes can be achieved.

[0030] Furthermore, the mounting plate 202 is symmetrically provided with sliding grooves 3, and a fixed rod 301 is slidably connected within one of the sliding grooves 3 of the mounting plate 202. A rotating shaft 302 is fixedly connected to the end of the fixed rod 301 away from the sliding groove 3, and a rotating rod 303 is rotatably connected to the rotating shaft 302. By rotating the rotating rod 303, the rotating rod 303 is forced to pass through the curtain ring, limiting the curtain ring's position, and thus, the curtain can be moved synchronously by the roller 203 rolling.

[0031] It should be noted that a second fixed rod 304 is slidably connected within the groove 3 of another mounting plate 202. A through groove 305 is provided through the second fixed rod 304. The dimensions of the through groove 305 are adapted to the rotating rod 303. When the reciprocating screw 2 drives the roller 203 on the mounting plate 202 to hang on the guide rail, the rotating rod 303, perpendicular to the first fixed rod 301, moves towards the second fixed rod 304, causing the end of the rotating rod 303 to pass into the through groove 305, thus securing the curtain rings and preventing them from detaching. This allows for better opening and closing of the curtains, improving their stability during opening and closing.

[0032] Based on the above embodiments, the working principle of this utility model is as follows:

[0033] In use, rotate the rotating rod 303 to make it level with the fixed rod 301. Pass the rotating rods 303 on both sides of the driver body 1 through the first and second non-fixed hanging rings. Rotate the rotating rods 303 again to make them perpendicular to the fixed rod 301. Then place the top of the driver body 1 between the first and second non-fixed hanging rings of the curtain. Subsequently, the reciprocating screw 2 rotates, causing the mounting plate 202 to slide synchronously. At this time, the rollers 203 will gradually conform to the curtain rail, allowing the driver body 1 to adapt to curtain rails of different sizes and shapes. Users can easily hang the driver body 1 on the curtain rail, or remove and move it as needed. With the installed driver body 1 and the adjustable rollers 203 hanging on the rail, the curtain can move synchronously when the driver body 1 moves. At the same time, the rotating rod 303, which is perpendicular to the fixed rod 301, moves toward the fixed rod 304, so that the end of the rotating rod 303 enters the through groove 305, and the curtain ring is fitted to prevent it from falling off. This allows the curtain to be opened or closed more effectively, improving the stability of the curtain during the opening or closing process.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0035] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
