Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-7, an intelligent shading roller blind for offices to be protected from damage due to wind according to an embodiment of the present invention includes a housing 1, a lower end surface of the housing 1 is an open structure, one side of the housing 1 is fixed to a wall, a roller shaft 2 is disposed inside the housing 1, the roller shaft 2 is fixedly connected to an inner wall of the housing 1 through two support plates 3, two ends of the roller shaft 2 penetrate through the support plates 3, a groove 4 is disposed at a left end of the roller shaft 2, a motor 5 is mounted on an inner wall of the housing 1 corresponding to the left end of the roller shaft 2, a rotating shaft 6 of the motor 5 is connected to the groove 4 in a clamping manner, a ball pulling assembly 7 is disposed at a right end of the roller shaft 2, a shading curtain 8 is wound on the roller shaft 2 between the support plates 3, inductive switches 9 (model: E3F-DS200C1, an effective detection distance of 2m, and a switch for performing photoelectric sensing by diffuse reflection of infrared rays).

The lower end of the window shade 8 is provided with a lower rod 10, the surface of the side wall of the backlight surface of the lower rod 10 is coated with a diffuse reflection coating 11, when wind blows the window shade 8, the window shade 8 drives the lower rod 10 to be raised, the diffuse reflection coating 11 on the side surface of the lower rod 10 sweeps light emitted by the inductive switch 9, accordingly diffuse reflection light is formed and received by the inductive switch 9, and the inductive switch 9 is closed after receiving the reflected light.

Wherein, pivot 6 is close to the one end of recess 4 and inlays and be equipped with the pin, the draw-in groove joint of rectangle structure on pin and the recess 4, pin and draw-in groove joint can avoid

pivot

6 and 3 relative displacement of taking place of spool for the transmission between pivot 6 and the spool 3 is more stable.

The motor 5 is communicated with the electrifying circuit through the induction switch 9, when the induction switch 9 is closed, the electrifying circuit is communicated with the motor 5, the motor 5 is electrified to work, and the reel 2 is driven to rotate to complete rolling of the window shade 8.

Wherein, the reel 2 is rotatably connected with the support plate 3 through a bearing, so that the stable transmission of the reel 2 is ensured.

The working principle is as follows: firstly, the shell 1 is fixed on a wall above a window, when the window shade is used, the window shade 8 is unfolded to a proper position through the bead pulling assembly 7 to shade strong light, when wind blows indoors through a vent, the window shade 8 is blocked at the vent, the wind blows the window shade 8, the blown window shade 8 drives the lower rod 10 to lift, when the acting force of the wind on the window shade 8 is small, the window shade 8 only swings in a small amplitude, no abnormal sound is generated, the work is not influenced, and at the moment, the lower rod 10 cannot cross the vertical position of the induction switch 9 when swinging, so the induction switch 9 cannot be triggered, and the window shade 8 keeps in the original position; when the acting force of wind on the window shade 8 is larger, the window shade 8 swings to a larger extent, at the moment, along with the large-amplitude swing of the window shade 8, the lower rod 10 also moves along with the window shade, the lower rod 10 frequently collides with a window, at the moment, the lower rod 10 can cross the vertical position of the inductive switch 9 when swinging, once the vertical position of the inductive switch 9 is reached, because the diffuse reflection coating 11 on the side wall of the lower rod 10 can reflect the special light emitted by the inductive switch 9, the inductive switch 9 can be closed after receiving the special light reflected by the diffuse reflection coating 11, so that the power-on circuit is communicated with the motor 5, the motor 5 is powered on to work, the reel 2 is driven by the rotating shaft 6 to rotate to complete the rolling of the window shade 8, when the lower rod 10 is positioned above the ventilation opening and is not acted by wind any more or the acting force is smaller, the lower rod 10 does not reflect the special light emitted, the inductive switch 9 is disconnected after receiving the special light which cannot be reflected, so that the power-on circuit is disconnected with the motor 5, the motor 5 does not work any more, and the shading curtain 8 stays above the ventilation opening and is not blown by wind.

As shown in fig. 8, in another embodiment, in order to reduce the sensitivity of the inductive switch 9, the inductive switch 9 may be connected to the housing 1 through the adjusting rod 12, so as to adjust the distance between the inductive switch 9 and the housing 1, when the window shade 8 is blown by wind to reach a certain angle, the inductive switch 9 is triggered, and then the motor 5 drives the winding shaft 2 to wind the window shade 8, which is not enough to blow the window shade 8 to reach a certain angle, and the sun is still shielded.

In another embodiment, in order to avoid sudden increase of wind force, which causes the lower rod 10 to be always in a higher position after passing through the vertical position of the inductive switch 9, the inductive switch 9 cannot receive continuous feedback of light reflected by the lower rod 10, so that the inductive switch 9 cannot be continuously closed, and the backlight of the window shade 8 may be coated with a diffuse reflection coating 11 for reflecting special light emitted by the inductive switch 9, thereby improving the sensitivity of the inductive switch 9 when the wind force is high, and ensuring that the window shade 8 is not damaged by wind.

As shown in fig. 9, in another embodiment, in order to avoid that the special light reflected by the diffuse reflection coating 11 on the window shade 8 is difficult to be quickly captured by the inductive switch 9, the reflective surface of the diffuse reflection coating 11 may be set in a wave-shaped structure, when the special light emitted by the inductive switch 9 is irradiated on the diffuse reflection coating 11, because the reflective surface is wave-shaped, a part of the arc curved surface can directly reflect the special light back toward the inductive switch, thereby facilitating the capture of the inductive switch 9.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
