Description

Technical Field

[0001] This utility model belongs to the field of venetian blind technology, and in particular relates to a venetian blind dimming device. Background Technology

[0002] Venetian blinds are windows that use slats that can be rotated to adjust the amount of light entering the room, thus achieving a balance between light control and ventilation. In some cases, the structure of venetian blinds completely replaces the structure of traditional glass windows to meet the needs of indoor lighting and ventilation.

[0003] Currently, when venetian blinds are opened, gaps are formed between the slats. These gaps act as channels for external airflow. Regarding light, while the slats can block direct sunlight, light diffused by the ground or other objects can still enter the room through these gaps. In some environments where venetian blinds are used directly as windows, the diffused light entering the room in high-light conditions can be untreated, affecting the indoor lighting and causing excessive light, which can negatively impact the comfort of people inside. Utility Model Content

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0029] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] This utility model embodiment provides a louvered dimming device, such as Figures 1-6 As shown, the louvered dimming device includes:

[0031] The outer frame 130 and the louver blades 110 assembled on the outer frame 130; the structure of the louver blades 110 and the outer frame 130 is basically the same as the louver structure in the prior art. The two ends of the louver blades 110 are respectively provided with deflection shafts 112, which extend into the outer frame 130 and are flipped and adjusted by the deflection mechanism provided inside the outer frame 130.

[0032] A light-shielding component 200 is hinged to a louver blade 110; the end face of the louver blade 110 facing the interior is provided with a support shaft seat 230; the light-shielding component 200 includes a light-filtering plate 201; one side of the light-filtering plate 201 is rotatably connected to the support shaft seat 230; and a counterweight strip is provided on the side of the light-filtering plate 201 away from the support shaft seat 230.

[0033] The filter plate 201 maintains a vertical state under the action of gravity as the louver blades 110 rotate. As the louver blades 110 deflect, the gaps between the louver blades 110 allow outside light to pass through, while some of the light entering the room passes through the vertically arranged filter plate 201 and is then dispersed into the room. Due to the light-blocking effect of the filter plate 201, the light entering the room is processed, thereby adjusting the light entering the room. In this application, the filter plate 201 mainly adopts the existing technology of filter plates that can weaken light intensity, thereby weakening the light intensity of the light entering the room. Those skilled in the art can also use filter plates with other filtering functions, such as reducing ultraviolet rays.

[0034] In this embodiment, the filter plate 201 can maintain a vertical state under its own weight. The vertical filter plate 201 is suspended between the gaps between the louver blades 110 after the deflection is opened. Some of the light entering the room through the gaps needs to pass through the filter plate 201 before entering the room. By using the filter plate 201 to process the light, the louver structure's ability to control the light entering is enhanced, thereby achieving the purpose of adjusting the indoor lighting effect.

[0035] As a preferred embodiment of this example, the end face of the louver blade 110 facing the indoor area is also provided with an electromagnet 240. When the counterweight strip provided on the filter plate 201 is magnetically attracted to the electromagnet 240, the filter plate 201 and the louver blade 110 deflect synchronously.

[0036] In this embodiment, the counterweight bar is made of an iron material that can be attracted, and its width is minimized. When the electromagnet 240 is energized, the magnetic attraction causes the filter plate 201 to adhere to the louver blade 110 and the filter plate 201 and the louver blade 110 to deflect synchronously. Here, the design requires the louver blade 110 to be adjusted to a perpendicular state to the ground before the magnetic connection is performed during the state transition.

[0037] In a preferred embodiment of this invention, the louver blade 110 is provided with deflection shafts 112 at both ends, the inner wall of one side of the outer frame 130 is provided with a deflection shaft seat for supporting the deflection shafts 112, and the inner wall of the other side is provided with a worm gear transmission 120, and the deflection shaft 112 on one side of the louver blade 110 is inserted into the worm gear transmission 120.

[0038] The worm gear transmission component 120 includes a support base 124, a housing 125, a worm gear 122, a deflection bushing 123, and a worm 121. A linkage shaft is provided between the worm gear 122 and the deflection bushing 123. The linkage shaft is mounted on the support base 124 inside the housing 125 via a bearing. The worm 121 is meshed with the worm gear 122.

[0039] The deflection bushing 123 has an open structure at the end away from the worm gear 122. The deflection shaft 112 is inserted into the deflection bushing 123 through the adjustment hole provided in the outer shell 125. The outer shell 125 has through holes on the two end faces adjacent to the adjustment holes. The two ends of the worm 121 are assembled in the through holes through bearings. The worm 121 and the outer shell 125 are rotatably connected through bearings.

[0040] In this embodiment, the outer frame 130 is equipped with an adjusting motor and a transmission shaft. The worm gear 121 is provided with an irregularly shaped transmission hole to accommodate the transmission shaft. The transmission shaft drives the worm gear 121 to rotate under the action of the adjusting motor. Under the transmission action of the worm gear 121 and the worm wheel 122, the louver blades 110 deflect. A set of worm wheel transmission components 120 corresponds to a set of louver blades 110. Since the transmission shaft passes through all the worm gears 121, the louver blades 110 will rotate synchronously when the transmission shaft rotates.

[0041] It should be noted that a conductive slip ring is also provided at the adjustment hole, and a power terminal adapted to the conductive slip ring is provided on the deflection shaft 112. The power terminal needs to supply power to the electromagnet 240 provided on the louver blade 110 to achieve the electromagnetic adsorption effect and complete the switching of the activation state of the filter plate 201.

[0042] It should be noted that, for the sake of simplicity, the foregoing embodiments are all described as a series of actions. However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to the present invention.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on these embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art can still combine, add, delete, or otherwise adjust the features of the various embodiments of this utility model according to the circumstances without conflict or creative effort, thereby obtaining different technical solutions that do not fundamentally depart from the concept of this utility model.
