Abstract

An external sunshading shutter device comprises a blade angle fixing frame, shutter blades, a blade opening-closing fixing frame, a blade angle control structure and a blade opening-closing control structure. One end of the blade angle control structure and one end of the blade opening-closing control structure are both fixed to the left end and the right end of each shutter blades. The angle control structure comprises a blade angle control motor, nylon drawing wires and angle control connecting components, and the blade opening-closing control structure comprises a blade opening-closing motor driving rotary shaft, a driven rotary shaft, a variable-section linkage strap and opening-closing control connecting components. The nylon drawing wires are used for tensioning to control blade angles, the blades are reset by means of elasticity of a tensional spring, and closing of the blades one by one from bottom to top is realized by means of the variable-section linkage strap. Angles and opening-closing of the blades are controlled by two motors respectively, three states of full-open, full-closed and upper-closed lower-open of the shutter blades can be realized, the problem of contradiction between sun-shading and lighting is solved, and sun-shading by the upper portion, lighting by the lower portion and energy saving and consumption reduction are realized.

Description

technical field [0001] The invention relates to an external sunshade louver device, in particular to a louver device capable of realizing angle control and separate control of opening and closing. Background technique [0002] External sun shading is of great significance to building energy saving. The fully closed state of external sun shading louvers can reduce the heat transfer of about 90% of the windows, and the half-open anti-glare state can also reduce the heat transfer of about 70% of the windows, so it has a good market prospect. However, the use of louvers will affect the efficiency of indoor natural lighting and may increase the lighting load of the building. Therefore, a good balance between shading and lighting is required. [0003] At present, there are fixed external sunshade louvers and the traditional built-in adjustable angle louvers are used as external sunshade louvers, and the louvers are integrated with windows, the louvers are placed in double-glazing,...
