Description

Technical Field

[0001] The utility model relates to the technical field of electric curtains, in particular to an electric rolling curtain device and an electric curtain. Background Art

[0002] With the rapid development of automation technology, electric curtains have been widely used in thousands of households because of their convenient use. The electric rolling curtain device is a power device for winding or unwinding the curtain fabric through an electric device. The traditional electric rolling curtain device usually uses a tubular motor with a model of Φ25mm to realize the lifting and lowering of the rolling curtain. However, at present, the Φ25mm tubular motor has a relatively long size, and its net length reaches 45cm, which is difficult to apply to relatively narrow windows. Moreover, it is relatively thick as a whole and can only fit a rolling tube with a diameter of more than 38mm, so the applicability is poor. Summary of the Utility Model

[0003] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide an electric rolling curtain device and an electric curtain, which have the advantage of improving applicability.

[0004] To achieve the above purpose and other related purposes, the following technical solutions are provided for the present utility model:

[0018] As a preferred embodiment of the utility model, several connecting blocks are provided on both sides of the mounting side plate, and a housing cover for encapsulating the power transmission mechanism is supported and connected to the mounting side plate through the connecting blocks.

[0019] By implementing the above technical solution, the power transmission mechanism can be protected by the housing cover.

[0020] As a preferred embodiment of the utility model, a locking block is provided in the mounting notch, and the DC motor is fixed to the locking block.

[0021] By implementing the above technical solution, it is convenient to install and fix the DC motor.

[0022] As a preferred embodiment of the utility model, several engaging ribs are annularly arranged on the outer surface of the connecting shaft seat.

[0023] By implementing the above technical solution, it is convenient to realize the snap fixation with the curtain roller through the engaging ribs.

[0024] As a preferred embodiment of the utility model, a holding disk is provided on one side of the connecting shaft seat close to the mounting side plate.

Detailed implementation manners

[0034] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification.

[0035] Please refer to Figures 1 to 3 , the first aspect of the embodiment of the present utility model provides an electric rolling curtain device, including: an installation housing 10, an installation notch 11 is provided at the top of the installation housing 10, and installation side plates 12 extending downward are provided on both sides of the installation housing 10; a DC motor 20 provided in the installation notch 11 and used to provide the driving force for winding / unwinding, and the DC motor in this embodiment can select the honeycomb curtain motor DV24AF; a connecting shaft seat 30 rotatably assembled on the installation side plate 12 and located below the installation housing 10 for connecting and fixing with the curtain roller; and a power transmission mechanism 40 carried on one of the installation side plates 12 for transmitting the driving force of the DC motor 20 to the connecting shaft seat 30 to drive the connecting shaft seat 30 to rotate.

[0036] Specifically, the installation side plate 12 and the installation housing 10 are fixedly connected by screws. The installation notch 11 extends from one side of the installation housing 10 to the other side to facilitate the embedding of the DC motor 20. A locking block 15 is provided in the installation notch 11, and the DC motor 20 is fixed to the locking block 15 to facilitate the installation and fixation of the DC motor 20.

[0037] The power transmission mechanism 40 is selected from the following structures alone or in combination: a gear transmission mechanism, a belt transmission mechanism or a sprocket transmission mechanism. In this embodiment, the power transmission mechanism 40 selects a gear transmission mechanism, and the gear transmission mechanism includes: a driving gear 41 rotatably assembled on the installation side plate 12 and connected to the power output shaft of the DC motor 20, and a driven gear 42 rotatably assembled on the installation side plate 12 and connected to the connecting shaft seat 30. The driving gear 41 and the driven gear 42 are meshed and transmitted. Through the meshing transmission of the driving gear 41 and the driven gear 42, the power drive of the connecting shaft seat 30 is realized; and the driving gear 41 and the driven gear 42 are meshed and transmitted through at least one transmission gear 43. Through the meshing transmission of the transmission gear 43, the installation positions of the driving gear 41 and the driven gear 42 can be more arbitrary, improving the installation adaptability, and enabling the driving gear 41 and the driven gear 42 to be set with smaller diameters to meet the requirements of miniaturization.

[0038] Among them, the driving gear 41 is rotatably connected to the mounting side plate 12 through a mounting shaft 411. A connecting rib hole 412 for connecting with the power output shaft of the DC motor 20 is provided on the mounting shaft 411. The shape of the connecting rib hole 412 can be in the form of a triangle, quadrilateral, pentagon, hexagon, semi-circle, waist circle, etc., so as to facilitate the driving connection between the DC motor 20 and the connecting rib hole 412. The driven gear 42 can also be rotatably connected to the mounting side plate 12 through a rotating shaft. The outer end of the rotating shaft extends out of the mounting side plate 12 and is in a prism shape. A rib hole corresponding to the prism shape is also provided on the connecting shaft seat 30, thereby realizing the rotational connection of the connecting shaft seat 30.

[0039] A number of connecting blocks 13 are provided on both sides of the mounting side plate 12. In this embodiment, two connecting blocks 13 are symmetrically provided on each side of the mounting side plate 12. A housing cover 14 for encapsulating the power transmission mechanism 40 is supported and connected to the mounting side plate 12 through the connecting blocks 13. Usually, a limiting groove is provided on the housing cover 14, and the connecting blocks 13 are embedded in the limiting groove to limit the position of the housing cover 14. The housing cover 14 can be fixedly connected to the mounting side plate 12 by screws, and the power transmission mechanism 40 can be protected through the housing cover 14.

[0040] Furthermore, a number of engaging ribs 31 are annularly provided on the outer surface of the connecting shaft seat 30. Usually, 4 - 8 engaging ribs 31 are evenly arranged. In this embodiment, 6 engaging ribs 31 are preferably provided. The curtain roll is sleeved on the connecting shaft seat 30, and the engaging ribs 31 facilitate the clamping and fixing with the curtain roller. And a holding disk 32 is provided on one side of the connecting shaft seat 30 close to the mounting side plate 12. The holding disk 32 can abut against both ends of the curtain roller to realize the limiting of the curtain roller and prevent axial movement.

[0041] During use, the curtain roller is installed and fixed on the connecting shaft seat 30. When the DC motor 20 works, the driving force can be transmitted through the power transmission mechanism 40 to drive the connecting shaft seat 30 to rotate, and then drive the curtain roller to rotate to realize the winding or unwinding of the roller blind. Since the DC motor 20 is arranged in the mounting housing 10, a DC motor 20 with a shorter size can be used, so as to meet the use requirements of narrower windows. By connecting and driving through the connecting shaft seat 30 and the curtain roller, the limitation of installing the tubular motor inside the curtain roller in the traditional way is avoided, so that the driving requirements of different specifications of curtain rollers can be adapted, and the applicability is improved.

[0042] In the second aspect of the embodiment of the present utility model, an electric curtain is provided, which includes the electric roller blind device as in the first aspect. The curtain roller is sleeved and fixed on the connecting shaft seat 30, and a curtain cloth is wound on the curtain shaft sleeve. Specifically, in this embodiment, it can be an electric soft yarn curtain, an electric Shangri-La curtain or an electric roller blind.

[0043] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not intended to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model.
