Abstract

The invention relates to the technical field of building sun shading, in particular to an anti-dazzle and light-transmitting sun shading curtain and a manufacturing method thereof.

Description

Anti-dazzle and light-transmitting sunshade curtain and manufacturing method thereof

Technical Field

Background

In the design and construction process of a house, in order to meet the natural lighting and visual comfort of the house, a large number of glass windows are adopted, but the adoption of the glass windows also increases the energy consumption of an air conditioner in a room, and simultaneously ultraviolet rays are easy to penetrate, so that a sun-shading curtain needs to be installed on the glass windows.

China's high-rise buildings are many, and the surface is mostly glass curtain wall, because its function is office space mostly, so often need the sunshade to be used for sheltering from summer sun and insolate in order to reach the purpose that reduces the building energy consumption and prevent the glare during the use. The common sunshade curtain can achieve the purpose after being pulled down, but the urban landscape brought by the glass curtain wall is lost for indoor use. And because the attention of the user is low, the user can not fold the box after pulling down, so that the originally open and permeable space becomes closed, and the user feels split from the external environment. That is, the traditional sunshade curtain usually only focuses on sunshade, does not focus on satisfying the requirement of natural lighting, and even though the sunshade curtain focuses on lighting, when the sunshade curtain with the same structure is used in different areas, the discomfort of glare generated by people still exists, and in addition, if the glass is opened for ventilation, the sunshade curtain is easily blown by wind, which may cause interference to the indoor and outdoor.

CN207377458U discloses a solar energy sensing sunshade screen, including the installation frame, the upper end diaphragm lower surface of installation frame is equipped with the sunshade screen shell, the inside both ends of sunshade screen shell are connected with the spool through the bearing, be equipped with the clockwork spring between the both ends of spool and the sunshade screen shell, the spool winding has the sunshade screen, provide the electric energy for the device through solar charging panel, with this can save a large amount of electric energy, and it is more convenient to use, and can drive the pivot through the motor and rotate, can pack up or put down receiving and releasing the acting as go-between through the pivot rotation, with this can drive the sunshade screen and put down or pack up, can respond to the power of sunlight through light sensor, with this judge whether pack up the sunshade screen, this solar energy sensing sunshade screen simple structure, and convenient for operation, not only can save a large amount of electric energy, but also can automatic control sunshade screen put down or pack up, it is more convenient to use. The above patent realizes that the sunshade screen is receive and release according to the power of sunlight automatically through the cooperation of illumination sensor and motor, pivot, but when putting the sunshade below, makes originally open penetrating space become closed, causes the sense of splitting of user and external environment.

CN103291203B provides a wind-resistant sun-shading curtain, belonging to the technical field of machinery. It has solved the poor problem of current (window) curtain wind resistance. The wind-resistant sun-shading curtain comprises a rolling curtain cloth, a window cover and a rolling pipe assembly, wherein the rolling pipe assembly is assembled in the window cover, the rolling curtain cloth is wound outside the rolling pipe assembly, two ends of the window cover are downwards fixedly connected with a side rail, one side of the side rail, facing the rolling curtain cloth, is provided with a longitudinal opening, two symmetrically arranged clamping strips are longitudinally arranged in the side rail, a gap is formed between the two clamping strips, and the upper opening of the gap is communicated with the window cover; the two side edges of the roller shutter cloth respectively penetrate through the longitudinal opening of the side rail at the same side and a gap between the two clamping strips, then extend into the inner cavity of the side rail and are transversely fixedly connected to the flexible positioning piece, the roller pipe assembly is provided with two symmetrically arranged annular grooves, when the roller shutter cloth is wound on the roller pipe, the two side edges of the roller shutter cloth are respectively wound at the corresponding annular grooves, and the outer diameter of the positioning piece is larger than the width of the gap between the two clamping strips. The above patent has stable in structure and reliable, the guidance quality is good, advantage that the wind-resistance is strong, but still sunshade and printing opacity can not compromise.

CN 102058310A is a single-side transparent sun-proof window shade, which is formed by uniformly sticking and covering the sticky side of a single-side transparent material commonly used in advertising materials on a transparent soft plastic window curtain cloth. The single-side transmission sun-proof window shade has the following advantages: 1. the dust is not easy to stick, and the cleaning is good even if the dust is stuck. 2. Various personalized patterns or advertisements can be sprayed and painted outside the single-side transparent sun-proof window curtain, and the appearance is attractive. 3. The outer side of the single-sided transparent sun-proof window shade can not be seen, but the outer side can be clearly seen; not only protects privacy, but also has better light transmittance. 4. The single-side transmission sun-proof window shade is lighter than a cloth curtain. 5. Because the inside can not be seen from the outside, the single-side transmission sun-proof window shade also has certain sun-proof function. Although the above patent mentions light transmission and sunshade, it does not consider discomfort of glare to a person and visual connection between the inside and the outside of a room, does not block visual communication between the inside and the outside of the room when shading the sun, and presents a good visual landscape to the outside.

CN 211647928U discloses an adjustable window shade device, the utility model discloses the structure adopts three kinds of hybrid window shades, can adjust the position that needs as required, also can directly rise it totally when not needing to use, the adoption is that the motor is controlled, convenient operation when using, long service life, can install other required window shade types as required, put the joint end outside the spool into the spout when using, close the fixed cover on the spool fixed station, make the buckle fasten, start the tubular motor, drive the swiveling wheel and rotate, sunshine is too dazzling, when needing to completely hide the light in the room, it can to adjust the window shade on the window shade; the curtain can be adjusted to the position of the light-transmitting curtain when certain brightness is needed and too strong sunlight is not needed; when ventilation is needed, the curtain is adjusted to the position of the ventilating curtain; when the complete ventilation is needed, the fixing cover at the upper end of the scroll fixing table is opened, so that the curtain is completely rolled up. Above-mentioned patent can realize printing opacity and ventilative, but need the part operation, when needs the ventilative, opens the printing opacity curtain and need ventilative, opens ventilative curtain, can not accomplish printing opacity and ventilative compromise.

Therefore, based on the defects of the existing sunshade curtain, the anti-dazzle and light-transmitting sunshade curtain and the manufacturing method thereof are provided.
