Folding sunshade curtain

Abstract

The invention provides a folding sunshade curtain. The folding sunshade curtain comprises guide rails, sliding blocks, transmission gears, upper sunshade pieces, lower sunshade pieces, a curtain bottom piece and a driving device, wherein the upper sunshade pieces and the lower sunshade pieces form groups in pairs, and the front side edges of each group of the upper sunshade piece and the lower sunshade piece are hinged to each other; a protruding sunshade part is arranged on the front side edge of each upper sunshade piece, and the front side edge of each lower sunshade sheet is provided witha light-transmitting notch matched with the corresponding sunshade part; the tail portions of the adjacent groups of the upper sunshade piece and corresponding lower sunshade piece are opposite and are rotationally connected with the corresponding sliding block, and mutual engaged transmission is achieved through the transmission gears to enable the adjacent groups of the upper sunshade piece andcorresponding lower sunshade piece to oppositely swing by a corresponding angle; the sliding blocks are connected with the guide rails in a sliding manner, the curtain bottom piece is connected to theportion below the lower sunshade piece located at the bottom and is in sliding connection with the guide rails; and the driving device extends along the guide rails and is in transmission connectionwith the curtain bottom piece. According to the folding sunshade curtain, full opening or shading can be achieved, and meanwhile semi-open light transmission and ventilation can be uniformly carried out.

Description

technical field [0001] The invention relates to the field of decorative building materials, in particular to a folding sunshade. Background technique [0002] The main function of sunshade products is to block the sun and resist the wind and sun, and at the same time, they can be opened at the right time for light transmission and ventilation. [0003] One of the sunshade products in the prior art is a flap type, which realizes light transmission and ventilation by synchronously changing the rotation range of the sunshade. However, this structure hinders the view greatly, even if the sun visor is fully opened, it is still blocked in front of the window or floor-to-ceiling glass. [0004] The other is the roller blind type, which can realize the overall lifting and opening and closing, and can also achieve the effect of semi-transparent and air-permeable within a certain range. For example, the sunshade disclosed in Patent No. 201410818120.2 is pressed down by the weight of...

AI Technical Summary

Problems solved by technology

However, the opening range of each slat is uncontrollable, and the working principle of this structural scheme must be that the lower slats of the entire sunshade curtain are opened first, and then the upper slats are gradually opened, so the entire sunshade cannot be achieved. Uniform opening of curtains for light transmission and ventilation

At the same time, due to the principle of applying the self-weight of the curtain, a part of the curtain at the top is not enough to open the curtain due to insufficient gravity above, and cannot be opened for light transmission and ventilation.
