Description

Electric sun-shading device for building window

Technical Field

The invention relates to an electric sun-shading device for a building window, and belongs to the technical field of sun-shading devices.

Background

Due to the day of energy conservation and emission reduction, the prior buildings increasingly apply an external sunshade technology on an enclosure (mainly a window). The external sun-shading technology is as follows: before the solar radiation passes through the window and enters the room, the external shading device (generally an external shading roller blind) reflects, deflects, refracts and absorbs the solar radiation to weaken the solar radiation, so that the comfortable environment in the building is maintained.

The existing sunshade technology in the prior art mostly adopts a non-automatic operation type retractable sunshade device, which not only has short service life, but also has poor sunshade effect. CN101638971 discloses a control method and device for a built-in full-automatic control sunshade double-glazing window, which is a sunshade louver body built in between double-glazing windows, and the device has the main defect that the louver body also seriously affects the indoor brightness while shading the sun, so that the window can work only when the light is turned on. Therefore, the existing sunshade facilities for buildings have the disadvantages of inconvenient operation, easy damage and serious influence on indoor brightness while shading sunlight.

Disclosure of Invention

The invention aims to solve the technical problem of overcoming the defects of the prior art and provides an electric sunshade device for a building window, which has a good sunshade effect and can give consideration to both ventilation and lighting effects and can be remotely and electrically adjusted.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows:

the utility model provides an electronic solar protection devices of building window, is including setting up fixed connection loop bar and two telescopic connection loop bars on building wall, two telescopic connection loop bar respectively with fixed connection loop bar is located on the same water flat and the same vertical line, fixed connection loop bar includes a plurality of fixed unit, telescopic connection loop bar include with the flexible unit of fixed unit one-to-one, fixed unit activity even has the one end of barn door, the other end of barn door has been seted up and has been reserved the slip track, be provided with the barn door dead lever on the flexible unit, the barn door dead lever passes reserve the slip track, telescopic connection loop bar inside has flexible pivot structure, is located the motor output shaft transmission of the terminal and the motor of the most inboard first festival axle and is connected.

The motor is a servo motor.

The motor is provided with an electric control switch, and the electric control switch is connected with the infrared receiver.

The number of the fixed units and the number of the telescopic units are N, wherein N is an integer greater than or equal to 3.

The number of the light barriers is 2.

And a reflective layer is coated on the outer surface of the light barrier.

The invention has the beneficial effects that: the invention provides an electric sun-shading device for a building window, which can be firstly applied to various building sunshades, wherein two telescopic connecting sleeve rods can adjust the rotation angle and the sun-shading area of a light-shading plate by adjusting the number of the extending sleeve rods, so that the sun-shading effect is improved. Secondly, the device has good ventilation effect, so that the temperature in the space is basically close to the outdoor temperature, the heat conduction energy consumption is reduced, and the energy-saving effect is improved. The sun-shading board is not arranged on the other side of the device in consideration of the sunlight height, so that the indoor room has better lighting and viewing effects. Finally, the telescopic degree of the telescopic connecting loop bar is changed by manually controlling the remote controller, so that remote adjustment is realized.

Detailed Description

The present invention is further described with reference to the accompanying drawings, and the following examples are only for clearly illustrating the technical solutions of the present invention, and should not be taken as limiting the scope of the present invention.

As shown in fig. 1 to 3, the present invention provides an electric sunshade device for a building window, which comprises a fixed connection loop bar 1 and two telescopic connection loop bars 2 arranged on a building wall 5, wherein the two telescopic connection loop bars 2 are respectively positioned on the same horizontal line and the same vertical line with the fixed connection loop bar 1. The fixed connecting loop bar 1 comprises a plurality of fixed units, and the telescopic connecting loop bar 2 comprises telescopic units 21 which are in one-to-one correspondence with the fixed units. The number of the fixed units and the telescopic units 21 is N, where N is an integer greater than or equal to 3, and is preferably 5.
