Electric sun-shade device of building window

Abstract

The invention discloses an electric sun-shade device of a building window. The electric sun-shade device comprises a fixing connecting sleeve rod and two telescopic connecting sleeve rods which are arranged on a building wall body, the two telescopic connecting sleeve rods are correspondingly located on the same horizontal line and the same vertical line with the fixing connecting sleeve rod, thefixing connecting sleeve rod comprises a plurality of fixing units, the telescopic connecting sleeve rods comprise telescopic units corresponding to the fixing units in a one-to-one mode, the fixing units are movably connected to one end of a light barrier, a reserved sliding rail is formed in the other end of the light barrier, the telescopic unit is provided with a light barrier fixing rod, thelight barrier fixing rod penetrate through the reserved sliding rail, the telescopic connecting sleeve rods are internally provided with telescopic rotary shaft structures, and the tail end of a firstsection shaft located at the innermost side is connected with a motor output shaft of a motor in a transmission mode. According to the provided electric sun-shade device of the building window, the sun-shade effect is good, the ventilation and illumination effects can both be considered, and the electric sun-shade device can be adjusted remotely and electrically.

Description

technical field [0001] The invention relates to an electric sunshade device for building windows, belonging to the technical field of sunshade devices. Background technique [0002] For the purpose of energy saving and emission reduction, current buildings have increasingly used external sunshade technology on the envelope (mainly windows). External shading technology refers to: before the solar radiation enters the room through the window, the solar radiation is reflected, deflected, refracted and absorbed through the external sun shading device (usually the external sun shading roller blind) to weaken the solar radiation and maintain the building. Comfort inside. [0003] At present, the sunshade technology in the prior art mostly adopts non-automatic rollable and stretchable sunshade devices. This type of sunshade device not only has a short service life, but also has poor sunshade effect. CN101638971 discloses a control method and device for a built-in fully automatic ...

Problems solved by technology

[0003] At present, the sunshade technology in the prior art mostly adopts non-automatically operated rollable sunshade devices. This kind of sunshade device not only has a short service life, but also has poor sunshade effect.

CN101638971 discloses a control method and device for a built-in fully automatic sunshade double-glazed window. The sunshade louver is built between the double panes. The main defect of the device is that the louver seriously affects the indoor environment while shading the sun. The brightness is so high that the light must be turned on to work

It can be seen that the sun-shading facilities of existing buildings also have the disadvantages of inconvenient operation, easy damage, and can seriously affect the indoor brightness while shading.
