Description

Technical Field

[0001] This utility model relates to the field of photosensitive color-changing curtain technology, and in particular to a dustproof structure for a photosensitive color-changing curtain. Background Technology

[0002] Photosensitive color-changing curtains, as a type of smart curtain, can automatically adjust their color and light transmittance according to light intensity, and have become increasingly popular in the market in recent years. These curtains are typically made of special photosensitive materials that change color under ultraviolet or visible light. However, due to the special nature of these photosensitive materials, the surface of the curtains easily attracts dust and dirt, which not only affects their appearance but may also reduce their light-sensitive effect and lifespan.

[0003] A search revealed Chinese Patent Publication No. CN209799825U, which discloses a color-changing curtain, relating to the field of curtain technology. This utility model includes an upper beam and a lower beam, with a curtain slat connected between them by a ladder rope. A hanging rope passing through the curtain slat connects the upper and lower beams. An LED light strip is fixed to one edge of the upper surface of the curtain slat, and the upper surface of the curtain slat is coated with a reflective coating. A drive power supply and controller are fixed to the inner surface of the upper beam, and a photosensitive module is fixed to the outer surface of the upper beam. The LED light strip on the curtain slat is electrically connected to the drive power supply, and the controller is also electrically connected to the drive power supply. This utility model, by installing color-changing LED light strips on the Venetian blind slats and using sensors to sense temperature and light to automatically control and adjust the curtain color, can change the reflective color of the curtain slats according to the external ambient temperature and light intensity, thereby adjusting the indoor color temperature to better suit people's mood, thus improving comfort and meeting living needs, and has good market prospects.

[0004] The aforementioned patent states in its description: "When the outside temperature is hot and the light intensity is high in summer, the curtain color can change to a cool color (such as green or blue, etc.) to make the indoor environment appear cool and refreshing; when the outside temperature is cold and the light intensity is low in winter, the curtain color will change to a warm color (such as yellow, red, etc.) to make the indoor environment appear warm and cozy; when night falls, it will change to a non-luminous curtain." Although the above curtains can change color according to the environment, subsequent cleaning requires frequent washing or vacuuming to remove dust. This not only increases maintenance costs but also damages the curtain material, reducing its lifespan. Therefore, to address these shortcomings, a dustproof structure for photosensitive color-changing curtains is proposed to solve the above problems. Utility Model Content

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] Reference Figures 1 to 3 This utility model provides an embodiment of a dustproof structure for a photosensitive color-changing curtain, including a mounting frame 1, an upper frame 2, and a lower frame 3. The mounting frame 1, upper frame 2, and lower frame 3 are all made of aluminum alloy. The top front end of the mounting frame 1 is fixedly connected to the rear side of the upper frame 2, and the bottom front end of the mounting frame 1 is fixedly connected to the rear side of the lower frame 3. The upper frame 2 and the lower frame 3 are both connected to the mounting frame 1 by welding, thereby providing support for the upper frame 2 and the lower frame 3. Multiple disassembly mechanisms 4 are slidably connected inside the upper frame 2 and the lower frame 3. The disassembly mechanisms 4 can slide stably due to the constraint of the upper frame 2 and the lower frame 3.

[0046] Specifically, the aluminum alloy mounting bracket 1 is welded to the upper frame 2 and the lower frame 3 to form a rigid support system. The sliding rail disassembly mechanism 4 inside the frame enables the quick assembly and disassembly of the curtain components. The whole structure forms a maintainable structure of "lightweight frame plus sliding disassembly", which combines structural stability and ease of operation.

[0047] Reference Figures 2 to 4 Each of the multiple disassembly mechanisms 4 includes a T-shaped column 41. The exterior of the multiple T-shaped columns 41 is slidably connected to the interior of the upper frame 2 and the lower frame 3, respectively. The upper frame 2 and the lower frame 3 restrict the T-shaped columns 41 so that they can slide stably. A connecting cylinder 42 is slidably connected to the exterior of the T-shaped columns 41, guiding the sliding installation of the connecting cylinder 42. Two sliding components 43 are slidably connected inside the connecting cylinder 42. Each sliding component 43 includes a sliding frame 4301. The exterior of the two sliding frames 4301 is slidably connected to the front and rear ends of the connecting cylinder 42, respectively. The connecting cylinder 42 restricts the sliding frames 4301 so that they can slide stably. A circular plate 430 is slidably connected to the inner wall of the sliding frame 4301. 2. The sliding frame 4301 is guided to slide by the circular plate 4302. Springs 4303 are fixedly connected to the far side of the two circular plates 4302. By fixing the springs 4303, the springs 4303 can be evenly stressed. Support rods 4304 are fixedly connected to the near side of the two circular plates 4302. The support rods 4304 provide support for the circular plates 4302. The two support rods 4304 are fixedly connected to the front and rear ends of the connecting cylinder 42 respectively by welding. The sliding component 43 has two obtuse angle plates 44 fixedly connected to its exterior. The obtuse angle plates 44 slide synchronously as the sliding component 43 moves.

[0048] A transmission column 45 is fixedly connected to the outside of the obtuse-angle plate 44. The sliding force is transmitted to the transmission column 45 through the obtuse-angle plate 44. Limiting blocks 46 are slidably connected to both ends of the connecting cylinder 42. The limiting blocks 46 can slide stably due to the restriction of the connecting cylinder 42. Two inclined openings 47 are opened inside the limiting blocks 46. The inclined openings 47 are adapted to the transmission column 45. The outside of the transmission column 45 is slidably connected to the inside of the inclined openings 47. Through the inclined openings 47, the transmission column 45 can push the limiting blocks 46 to move a certain distance. Triangular blocks 48 are fixedly connected to the adjacent side of the two limiting blocks 46. During the sliding process, the limiting block 46 drives the triangular block 48 to slide synchronously. The outer sides of the two triangular blocks 48 are respectively slidably connected to the inner sides of the T-shaped column 41. The triangular blocks 48 slide into the inner side of the T-shaped column 41 to complete the installation and engagement. The outer side of the multiple disassembly mechanisms 4 is fixedly connected with a dustproof layer 5. The dustproof layer 5 is a transparent or semi-transparent PET dustproof film with high light transmittance and antistatic properties. The top of the mounting frame 1 is slidably connected with multiple sliding hooks 6. The bottom side of the multiple sliding hooks 6 is fixedly connected with the curtain body 7. The curtain body 7 is made of photosensitive color-changing material. The dustproof layer 5 covers the outer surface of the mounting frame 1.

[0049] Specifically, the disassembly mechanism 4 achieves quick disassembly and assembly through an elastic locking structure. The T-shaped column 41 and the connecting cylinder 42 form the main sliding frame 4301. The sliding component 43 uses the spring 4303 to push the circular plate 4302 to drive the transmission column 45. The inclined guide of the inclined opening 47 drives the limit block 46 to extend and retract radially. The mechanical interlock formed by the triangular block 48 and the T-shaped column 41, combined with the protection of the PET dustproof film, forms a quick disassembly with "elastic buckle plus self-locking limit". This ensures the installation stability of the curtain body 7 and facilitates the maintenance and replacement of the dustproof layer 5.

[0050] Reference Figures 7 to 9A drive mechanism 8 is fixedly connected to the top of the mounting bracket 1. The drive mechanism 8 includes a motor 81, which provides a drive source. The motor 81 is externally fixedly connected to the inside of the mounting bracket 1. By fixing the motor 81, the motor 81 can operate stably. A transmission assembly 82 is fixedly connected to the drive end of the motor 81. A support rod 85 is rotatably connected to the top of the mounting bracket 1. The support rod 85 can rotate stably by the constraint of the mounting bracket 1. The transmission assembly 82 includes a rotating shaft 8201. The front end of the rotating shaft 8201 is fixedly connected to the drive end of the motor 81. The rotating shaft 8201 is driven to rotate by starting the motor 81. Gears 8202 are fixedly connected to the outside of the rotating shaft 8201 and the outside of the support rod 85, and are fixed by welding. The gear 8202 is fixed to the drive support of the rotating shaft 8201, and the gear 8202 outside the rotating shaft 8201 drives the gear 8202 outside the support rod 85 to rotate. The rear side of the rotating shaft 8201 is fixedly connected to the front side of one of the driving wheels 83. The rotating force is transmitted to the driving wheel 83 through the rotating shaft 8201. The rear side of the transmission assembly 82 and the support rod 85 are both fixedly connected to the driving wheel 83. The driving wheel 83 is fitted with a belt 84. The rotating force is transmitted to the belt 84 through the driving wheel 83. The left and right ends of the mounting frame 1 are rotatably connected to the support column 86. The support column 86 can rotate stably through the restriction of the mounting frame 1. The rear side of the support column 86 is fixedly connected to the driven wheel 87. The support column 86 provides support for the rotation of the driven wheel 87.

[0051] Specifically, the drive mechanism 8 adopts a dual-wheel synchronous transmission system to realize the automatic control of the curtain. The motor 81 synchronously drives the rotating shaft 8201 and the support rod 85 through the gear set 8202, which drives the double-sided driving wheel 83 to rotate through the belt 84 and the driven wheel 87, forming a composite transmission chain of "motor 81 drives gear 8202 drives belt 84". The symmetrically arranged support column 86 and driven wheel 87 realize the smooth opening and closing of the curtain body 7, which not only ensures the synchronization of transmission but also reduces operating noise, meeting the intelligent adjustment needs of the photosensitive color-changing curtain.

[0052] Reference Figures 5 to 6 The driven wheel 87 is sleeved inside the belt 84. The belt 84 transmits the rotational force to the driven wheel 87. A connecting rope 88 is fixedly connected to the outside of the belt 84. The belt 84 drives the connecting rope 88 to move synchronously during the movement. The bottom end of the connecting rope 88 is fixedly connected to the outside of the curtain body 7. The connecting rope 88 drives the curtain body 7 to move, thereby completing the opening and closing of the curtain body 7.

[0053] Specifically, the driven wheel 87 forms a power transmission chain with the belt 84 and the connecting rope 88, which converts the rotational motion into the vertical lifting and lowering of the curtain body 7, forming a drive of "wheel and belt linkage plus rope traction". This design uses flexible connection to reduce the impact of operation and ensures the stability and quietness of the photosensitive color-changing curtain during opening and closing.

[0054] Working principle: First, the multiple connecting cylinders 42 on the dustproof layer 5 are aligned with the T-shaped column 41 and slid in, while simultaneously pushing the sliding component 43 to slide. During the sliding process of the sliding frame 4301, the spring 4303 is compressed, allowing the spring 4303 to store elastic potential energy, which then provides a force in the opposite direction to the sliding component 43 for resetting. During the sliding process of the obtuse angle plate 44, the transmission column 45 is also driven to slide through the obtuse angle plate 44. At this time, the limiting block 46 inside the limiting block 46 guides the thrust of the transmission column 45, so that the two opposing transmission columns 45 respectively drive a triangular block 48 to the opposite side. The slide allows the T-shaped post 41 to engage inside the connecting cylinder 42. Then, the pushing force on the sliding frame 4301 is released. At this time, the force of the spring 4303 returning to its original position is transmitted to the limiting block 46 through the transmission post 45, which drives the triangular block 48 to slide and engage inside the T-shaped post 41, completing the connection between the connecting cylinder 42 and the T-shaped post 41. This allows for quick assembly and disassembly of the dustproof layer 5. The dustproof layer 5 prevents dust from falling onto the curtain body 7, eliminating the need for direct contact cleaning of the curtain body 7 and extending its service life. At the same time, the quick disassembly improves the efficiency of cleaning the dustproof layer 5.

[0055] Then, the motor 81 is started, which drives the rotating shaft 8201 to rotate, thereby driving the externally fixed gear 8202 to rotate, which in turn drives another gear 8202 to rotate. At this time, the other gear 8202 drives the support rod 85 to rotate, so that the rotating shaft 8201 and the support rod 85 rotate relative to each other, which then drives the drive wheel 83 to rotate, and then drives the driven wheel 87 to rotate through the belt 84, so that the belt 84 can drive the connecting rope 88 to move left and right. Then, by pulling the connecting rope 88, the curtain body 7 moves left and right to open. The motor 81 is started in reverse, the drive wheel 83 drives the belt 84 to move in the opposite direction, and the curtain body 7 closes. No manual operation is required, thereby improving its flexibility.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
