The directional hinge 2 is provided with a torsion spring, preferably a single-arm torsion spring 3, the front end of which is provided with an extending torsion arm 301, and the rear end of which is provided with a positioning column 302 formed by bending towards the axis.
In order to solve the installation problem of the single-arm torsion spring 3, an installation space 203 with an outward opening is arranged at the outer end of the directional hinge 2 between the upper hinge shaft 201 and the lower hinge shaft 201 of the directional hinge 2, a sleeve spring column 204 is arranged in the installation space 203, and the single-arm torsion spring 3 is sleeved on the sleeve spring column 204.
The sleeve spring column 204 is provided with a positioning groove 2041 with an outward opening, and the depth of the positioning groove 2041 is larger than or equal to the axial length of the single-arm torsion spring 3; in application, the positioning post 302 at the inner end of the single-arm torsion spring 3 is clamped at the inner end of the positioning groove 2041, so that the inner end of the single-arm torsion spring 3 is fixed, and cannot twist around the sleeve spring post 204.

In order to smoothly complete the folding, the direction of the force applied by the torsion spring on the lower solar panel 101 is opposite to the direction of the force applied by the other torsion spring on the upper solar panel 101, so that the whole sunshade curtain 1 can be folded in a zigzag shape when being folded.
Two directional hinges 2 are provided between two adjacent solar panels 101, respectively provided at left and right ends between the two solar panels 101. A light transmission gap 102 between two adjacent solar panels 101 is arranged between the left and right directional hinges 2, and the width of the light transmission gap 102 is set according to the requirement to ensure that proper light enters a room from a window when the sunshade curtain 1 is fully unfolded.
The sunshade 1 provided as described above is suspended at its upper end from the front end of the suspension member 12 in a hinged manner.
As shown in fig. 2, 3, 7, 8 and 9, the lifting mechanism is provided with two lifting screw rods 4 symmetrically and vertically arranged on two sides of a window, the top ends of the two lifting screw rods 4 are respectively provided with a bevel gear I401, two left driving shafts 5 and two right driving shafts 5 which are horizontally arranged in a coaxial line are arranged between the top ends of the two lifting screw rods 4, the left end of the left driving shaft 5 and the right end of the right driving shaft 5 are respectively provided with a bevel gear II 501 matched with the bevel gear I401, the bevel gear I401 of the left lifting screw rod 4 is meshed with the bevel gear II 501 of the left driving shaft 5, the bevel gear I401 of the right lifting screw rod 4 is meshed with the bevel gear II 501 of the right driving shaft 5, a through shaft motor 10 is arranged between the left driving shaft 5 and the right driving shaft 5, and the left driving shaft 5 and the right driving shaft 5 are respectively connected on two sides of the through shaft motor 10 through a coupler 11. Thus, the through shaft motor 10 rotates, and the two lift screws 4 on both sides of the window can be rotated synchronously.
The lifting mechanism also has lifting means, preferably provided as lifting arms 8. The rear end of the lifting arm 8 is provided with two vertical threaded holes 801, the lifting arm 8 is sleeved on the lifting screw rod 4 through the matching of internal threads in the vertical threaded holes 801 and external threads of the lifting screw rod 4, and the heights of the two lifting arms 8 are equal.
Except for the lifting arm 8, the entire transmission mechanism of the lifting mechanism is covered by the decorative shell 6, and only the lifting groove 601 in which the lifting arm 8 extends and lifts up and down is left.
The upper surface of the lifting arm 8 is a sliding surface 802, the front end of the lifting arm 8 is provided with a reverse-folding hook 803 formed by upward reverse folding, and the sliding surface 802 extends forward into a hook groove 8031 of the reverse-folding hook 803; correspondingly, a columnar pulley 702 running on the sliding surface 802 is arranged on the bottom edge of the solar panel 101 at the bottom end of the sunshade curtain 1, and the pulley 702 can slide into the hook groove 8031 along the sliding surface 802 and be hooked downwards by the reverse-folding hooks 803.
Pulley 702 is mounted on a pulley frame 7, and pulley frame 7 is mounted on the bottom side of solar panel 101 at the bottom end. Pulley frame 7 has pulley space 701 which opens downward and communicates front and back, pulley 702 is installed in pulley space 701, and pulley 702 is spaced from the top of pulley space 701, so that return hook 803 can hook pulley 702 downward from above pulley 702.
The return hook 803 is located right under the upper end hanging position of the sunshade curtain 1 so that the sunshade curtain 1 can be in a vertically hanging state when the return hook 803 hooks the sunshade curtain 1 downward.
The front end of the sliding surface 802 is higher than the rear end, so that the sliding surface can play a guiding role when being folded; the solar panel 101 at the bottom end of the sunshade curtain 1 is subjected to the backward force of the torsion spring.
The solar sunshade device for the window is convenient to unfold and fold on the premise of ensuring the damage prevention and the falling prevention safety of the device.
As shown in fig. 1, 9 and 12, the sunshade mode is that the sunshade curtain 1 is fully or partially unfolded outside the window in a hanging mode, and when the sunshade curtain 1 is fully unfolded, proper bright light still enters the room from the window.
The spreading mode is that the sunshade curtain 1 is spread downwards by the gravity of the sunshade curtain 1 and/or the pulling force exerted by the descending of the lifting arm 8.
The folding mode is that the lifting arm 8 lifts upwards, and the sunshade curtain 1 is folded in a Z shape under the action of the directional force applied by the single-arm torsion spring 3.
The control mode is as follows: the power switch is turned on and off manually, or turned on and off by remote control, or turned on and off intelligently.
The following describes an embodiment of the sunshade 1 to be unfolded and folded in combination with the above-described technical solution:
folding state: as shown in fig. 12, the lift arms 8 on both sides of the solar sunshade device for window are lifted to the highest position, and the sunshade curtain 1 is lifted by the lift arms 8 to be folded in a zigzag manner between the lift arms 8 and the hanging members 12, and is restricted by the lift arms 8 and the hanging members 12 to be in a safe state not to fall. In this state, the bottom edge of the lowermost solar panel 101 of the sunshade curtain 1 is positioned at the rear end of the sliding surface 802 of the lift arm 8.
The sunshade curtain 1 is unfolded: as shown in fig. 1, 2, 4, 8 and 9, the through shaft motor 10 rotates to enable the lifting arms 8 at two sides to drop downwards, and under the action of gravity, the solar panel 101 at the bottommost end of the sunshade curtain 1 descends along with the descending of the lifting arms 8, and the sunshade curtain 1 gradually stretches downwards.
When the sunshade curtain 1 is extended downwards to a proper length, the extension can be stopped when the indoor brightness requirement is met.
When the sunshade curtain 1 is required to be fully extended, the lifting arm 8 continues to descend, and the bottom edge of the bottommost solar panel 101 of the sunshade curtain 1 is subjected to the outward component force of gravity of the sunshade curtain 1 in the subsequent descending process of the lifting arm 8, so that the pulley 702 slides outwards on the sliding surface 802. When the pulley 702 slides to near the front end of the lifting arm 8, the return hook 803 starts to extend into the gap between the pulley 702 and the top of the pulley space 701. The lifting arm 8 continues to descend and the pulley 702 continues to slide into the hook slot 8031. Lifting arm 8 continues to descend again to return hook 803 pulling pulley 702 downward. When the downward pulling force of the reverse folding hooks 803 overcomes the acting force of the single-arm torsion spring 3 on the lower solar panel 101 to the maximum extent, the included angle between two adjacent solar panels 101 is infinitely close to 180 degrees, and the sunshade curtain 1 tends to be in a flat state. At this time, the sunshade curtain 1 is vertically tensioned, is in a stable state against wind, and has an aesthetic appearance. In this state, external light can still enter the room through the light-transmitting gap 102.
The folding process of the sunshade curtain 1 comprises the following steps: as shown in fig. 7, 8 and 9, with respect to the expansion of the sunshade curtain 1, the through-shaft motor 10 rotates reversely, the lifting arms 8 on both sides rise upward, the bottom edge of the solar panel 101 at the bottommost end of the sunshade curtain 1 receives upward lifting force through the pulley 702, and the bottom edge of the solar panel 101 is folded backward under the backward force applied by the single-arm torsion spring 3 and the guiding action of the downward slope of the sliding surface 802, which is higher than the rear end, and the pulley 702 slides along the sliding surface 802 toward the rear end of the lifting arm 8. As the lifting arm 8 is lifted up, the bottom solar panel 101 of the sunshade curtain 1 is folded back to the extent that the upper solar panel 101 is subjected to the lifting force, and the upper solar panel 101 is folded outwards relative to the adjacent upper solar panel 101 under the forward force exerted by the single-arm torsion spring 3. In this way, the lifting arm 8 is lifted up continuously, and the upper solar panel 101 is folded alternately forward and backward until the folding is completed.
Example two
As shown in fig. 10 and 11; the difference from the first embodiment is that: a limiting piece 9 is arranged above the sliding surface 802, the front end of the limiting piece 9 is a movable connecting end 901, and the movable connecting end 901 is hinged with a reverse-folding hook 803; the rear end of the limiting piece 9 is a detachable connecting end 902, and the detachable connecting end 902 is detachably connected with the rear end of the lifting arm 8; the spacing between the stop 9 and the running surface 802 is greater than the diameter of the pulley 702. Thus, the pulley 702 can be restrained on the sliding surface 802 and can slide back and forth on the sliding surface 802 both when folding and unfolding. The sunshade curtain 1 can be always constrained by the lifting arm 8 in the process of unfolding and folding the sunshade curtain 1, and the reliability of unfolding and folding can be enhanced.
Here, the rear end of the stopper 9 is a detachable connection end 902, so that the detachable connection end 902 and the rear end of the lifting arm 8 can be separated during installation, the pulley 702 is fitted between the stopper 9 and the sliding surface 802, and then the detachable connection end 902 and the rear end of the lifting arm 8 are folded and connected. The detachable connection mode can be that the rear end of the rear end limiting piece 9 of the lifting arm 8 is provided with a bolt hole with the same axis, and then the bolt hole is fixedly connected by a bolt 903 and a nut.
The above embodiments are only for the purpose of more clearly describing the present invention and should not be construed as limiting the scope of the present invention, and any equivalent modifications should be construed as falling within the scope of the present invention.
