Description

Technical Field

[0001] This utility model relates to an electric curtain with a retractable shell. Background Technology

[0002] Curtains, as an indispensable part of home decoration, have long transcended their basic functions of simply blocking light and protecting privacy, becoming an important element in enhancing the aesthetics of the interior. With the popularization of the smart home concept, motorized curtains have gradually become the choice of many families due to their convenience and intelligent features. However, traditional motorized curtains have some inconveniences, especially the size issues during the customization process.

[0003] Because windows in homes vary in size, consumers must first accurately measure their own windows and then order custom-made curtains of a specific length from the manufacturer based on those measurements. This process not only increases the amount of preparation work for consumers but also results in long waiting times. Furthermore, once the curtains are made and installed, their applicability is fixed, limited to windows of that specific size. If the window size needs to be changed due to renovations or other reasons, the custom-made motorized curtains become unusable and must be discarded, leading to a waste of resources.

[0004] Based on this, some manufacturers have developed retractable curtain tracks. However, current retractable curtain tracks are limited to adjusting the track length, and maintenance is relatively inconvenient after installation and use. Utility Model Content

[0005] The purpose of this invention is to provide an electric curtain with a retractable shell to solve the technical problems mentioned in the background section.

[0006] The technical solution to achieve the purpose of this utility model is: an electric curtain with a retractable shell, including a retractable track and a main transmission box and a secondary transmission box respectively disposed at both ends of the retractable track, wherein the main transmission box and the secondary transmission box are connected in a transmission manner; the retractable track includes an outer rail and a middle rail, wherein the outer rail and the middle rail are slidably connected; the outer rail includes a first outer rail and a second outer rail, wherein one end of the first outer rail is fixedly connected to the main transmission box and the other end is slidably connected to one end of the middle rail, the other end of the middle rail is fixedly connected to the secondary transmission box, and the second outer rail is slidably connected to the first outer rail.

[0007] Furthermore, the first outer rail and the second outer rail are arranged side by side, and a cavity is formed between the first outer rail and the second outer rail. The cavity includes a track cavity and a device cavity. The retractable track also includes an inner rail, which is set in the track cavity. One end of the inner rail is fixedly connected to the main drive box, and the other end is slidably connected to one end of the middle rail.

[0008] Furthermore, a drive motor is installed in the cavity of the device, and the drive motor is fixed on the main transmission box and connected to the main transmission box in a transmission manner.

[0009] Furthermore, the device cavity is located on the side close to the second outer rail.

[0010] Furthermore, the inner rail includes a first inner rail and a second inner rail arranged side by side.

[0011] Furthermore, the main transmission box and the auxiliary transmission box are connected by belt drive, and belt grooves are provided in the middle rail and the inner rail.

[0012] Furthermore, the first outer rail and the second outer rail are slidably connected by a sliding assembly, which includes a matching slide rail and a sliding groove. One of the first outer rail and the second outer rail is provided with a sliding groove, and the other is provided with a slide rail.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects:

[0014] (1) The track length of this utility model is telescopic, which can be adapted to different installation distances and can reduce the packaging and transportation volume and reduce transportation costs. On this basis, the outer rail is set as the first outer rail and the second outer rail. The first outer rail and the second outer rail can be slidably connected. After the second outer rail is pushed towards the user, the cavity between the first outer rail and the second outer rail can be exposed, which is convenient for debugging, installation and maintenance.

[0015] (2) The curtain slats and drive motor of this utility model can be fully covered without being exposed by the second outer rail, which is highly integrated and aesthetically pleasing.

[0016] (3) The equipment cavity of this utility model is located on the side close to the second outer rail, so that the drive motor is closer to the user side, which facilitates debugging, installation and maintenance. Attached Figure Description

[0032] The first outer rail 3-1 and the second outer rail 3-2 are arranged side by side, forming a cavity between them. This cavity includes a track cavity and an equipment cavity. The retractable track also includes an inner rail 5, which is disposed within the track cavity. One end of the inner rail 5 is fixedly connected to the main drive box 1, and the other end is slidably connected to one end of the middle rail 4. The inner rail 5 includes the first inner rail 5-1 and the second inner rail 5-2 arranged side by side. In this embodiment, the electric curtain is a single-opening six-panel sliding curtain. The six panels open and close within the double tracks via a trolley 9. The arrangement of the trolley 9 within the double tracks is a relatively mature technology in the industry and will not be described further here.

[0033] A drive motor 6 is installed in the equipment cavity. The drive motor 6 is fixed on the main transmission box 1 and is connected to the main transmission box 1 for transmission.

[0034] The equipment cavity is located on the side closer to the second outer rail 3-2, which brings the drive motor 6 closer to the user's side, making it easier to debug, install and maintain.

[0035] The main drive box 1 and the auxiliary drive box 2 are connected by belt drive, and belt grooves 7 are provided in the middle rail 4 and the inner rail 5. In this embodiment, the drive motor 6 is fixed to the main drive box 1, and the output end of the drive motor 6 is connected to the main drive box 1. The main drive box 1 is connected to the auxiliary drive box 2 by belt drive, and at the same time, the belt drives the trolley 9 located in the track to move, thereby controlling the opening and closing of the curtain slats.

[0036] The first outer rail 3-1 and the second outer rail 3-2 are slidably connected by a sliding component 8. The sliding component 8 includes a matching slide rail and a sliding groove. One of the first outer rail 3-1 and the second outer rail 3-2 is provided with a sliding groove, and the other is provided with a slide rail. The slide rail is embedded in the sliding groove.

[0037] The track length of this utility model is extendable to adapt to different installation distances, and it can reduce the packaging and transportation volume and reduce transportation costs. On this basis, the outer rail 3 is set as a first outer rail 3-1 and a second outer rail 3-2. The first outer rail 3-1 and the second outer rail 3-2 are slidably connected. After the second outer rail 3-2 is pushed towards the user, the cavity between the first outer rail 3-1 and the second outer rail 3-2 can be exposed, which facilitates debugging, installation and maintenance.

[0038] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
