Technical Field
[0001] This utility model relates to the field of Venetian blind technology, and in particular to an electrically adjustable Venetian blind. Background Technology
[0002] Venetian blinds are primarily made of aluminum alloy, wood, and bamboo with a baked enamel finish. They are durable, easy to clean, non-aging, colorfast, provide sun shading, heat insulation, breathability, and fire resistance. They are suitable for high-end office buildings, residences, hotels, villas, and other venues. They can also be paired with decals to create a fresher and more elegant ambiance. They are available in both manual and electric control modes, allowing you to adjust the angle of the blinds to control the amount of light entering the room. The blind angle can be adjusted to the most suitable position. They are used for decorating windows and doors in bedrooms, bathrooms, and conference offices.
[0003] Most existing motorized dimming Venetian blinds only have a single function of adjusting the slat angle or raising and lowering the whole unit, which is difficult to meet the needs of dimming and raising / lowering at the same time. Although some products have dual functions, they require multiple motors to drive them, resulting in complex Venetian blind structures, high manufacturing costs and energy consumption. Moreover, most of the slats are fixed structures, and cleaning can only wipe the surface, making it difficult to thoroughly clean the dust accumulated in the gaps. Disassembly often requires professional tools or complete disassembly of the whole unit, making the whole operation more cumbersome and increasing the difficulty of maintenance.
[0004] Therefore, those skilled in the art have provided an electrically operated dimming Venetian blind to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an electric dimming Venetian blind. Dimming and raising and lowering can be completed automatically with only a single motor, which is convenient to operate and saves energy and overall manufacturing costs. When disassembling, you only need to pull the unlocking block and press the pressing block to remove the blind as a whole. The whole process is simple to operate, which makes it convenient to replace the blind.
[0006] To achieve the above objectives, the present invention provides the following technical solution: An electric dimming Venetian blind includes a mounting box and a base plate. A motor is fixedly installed on one side inside the mounting box. A main shaft is fixedly installed at the output end of the motor. A spur gear is fixedly installed on one side of the main shaft. An auxiliary shaft is rotatably installed at the front end inside the mounting box. A half gear is fixedly installed on one side of the auxiliary shaft. Fixing blocks are fixedly installed on both sides of the lower end of the auxiliary shaft by angle ropes. Pressing blocks are slidably installed at the front end of the two fixing blocks. Locking blocks are fixedly installed at the rear end of the lower end of the two pressing blocks. Slider blocks are installed at the lower end of the two fixing blocks. Locking grooves are opened at the rear end of the two slider blocks. Fixing ropes are fixedly installed at the lower end of the two slider blocks. Both sides of the main shaft are fixedly equipped with winding ropes, and both winding ropes are fixedly equipped with connecting blocks at their lower ends. Each connecting block has a limit groove on its opposite side. An unlocking block is slidably provided at the front end of the base plate, and a connecting plate is fixedly provided at the rear end of the unlocking block. Both sides of the connecting plate are hinged with rotating blocks, and each rotating block has a limit block hinged on its opposite side.
[0007] Furthermore, the half gear and the spur gear are meshed together, and the main rotating shaft is externally rotatably disposed inside the mounting box near the rear end.
[0008] Furthermore, the lower ends of the front ends of both card blocks are inclined, and the outer front ends of the two card blocks are respectively located inside the rear ends of the two card slots.
[0009] Furthermore, springs are fitted around the rear ends of both pressing blocks, and the front ends of the two springs are respectively fixedly installed inside the front ends of the two fixing blocks.
[0010] Furthermore, a compression spring is fixedly provided at the front end of the connecting plate, and the front end of the compression spring is fixedly provided inside the front end of the base plate. The connecting plate is sleeved inside the unlocking block near the rear end.
[0011] Furthermore, the two limiting blocks are respectively disposed on opposite sides inside the two limiting grooves, and the upper ends of the opposite sides of the two limiting blocks are inclined. The lower ends of the two connecting blocks are disposed inside the base plate, and the upper end of the base plate is disposed at the lower end of the mounting box.
[0012] Furthermore, multiple curtain slats are fixedly arranged between the two fixed ropes, and the two winding ropes are respectively sleeved inside the multiple curtain slats. An infrared sensor is fixedly arranged at the front end of the mounting box.
[0013] This utility model has the following beneficial effects: 1. This utility model proposes an electric dimming Venetian blind. When the overall angle of the blind slats needs to be adjusted, the motor drives the main shaft to rotate, causing the spur gear to drive the half gear to rotate synchronously, which in turn causes the auxiliary shaft to rotate. The angle rope is then wound up, and the fixed block moves upward. The upward movement of the fixed block will pull one side of all the blind slats upward synchronously through the fixed rope, thereby causing the blind slats to deflect and the angle to be adjusted. When the entire Venetian blind needs to be retracted, the motor drives the main shaft to rotate, causing the winding rope to tighten. The base plate will then drive all the blind slats to gradually retract upward. Through the drive of a single motor, both blind slat angle adjustment and overall lifting and lowering are achieved. The entire process does not require an additional power source, which improves the convenience of use and reduces the overall manufacturing cost and energy consumption.
[0014] 2. The electric dimming Venetian blind proposed in this utility model allows for the replacement of the entire blind slat when the unlocking block is pulled first, causing the limiting block to slide relative to the limiting block and disengage from the limiting groove. Then, the connection between the base plate and the connecting block is released. Subsequently, the pressing block is pushed in sequence to disengage the locking block from the locking groove. Then, the slider can be pulled out from the fixing block. After that, the entire blind slat can be removed, making it easier to clean or replace, thereby improving the service life of the entire blind slat and reducing the difficulty of maintenance.

[0017] 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.
[0018] Reference Figures 1-6 One embodiment provided by this utility model: An electric dimming Venetian blind includes a mounting box 1 and a base plate 5. A motor 14 is fixedly installed on one side inside the mounting box 1. A main rotating shaft 13 is fixedly installed at the output end of the motor 14. A spur gear 11 is fixedly installed on one side of the main rotating shaft 13. An auxiliary rotating shaft 12 is rotatably installed at the front end inside the mounting box 1. A half gear 10 is fixedly installed on one side of the auxiliary rotating shaft 12. Fixing blocks 2 are fixedly installed on both sides of the lower end of the auxiliary rotating shaft 12 by angle ropes. Pressing blocks 15 are slidably installed at the front end inside the two fixing blocks 2. Locking blocks 18 are fixedly installed at the rear end of the lower end of the two pressing blocks 15. Slider 16 is installed at the lower end inside the two fixing blocks 2. A locking groove 19 is opened at the rear end of the two sliders 16. Fixing ropes 3 are fixedly installed at the lower end of the two sliders 16. Half gear 10 and spur gear 11 are meshed and connected. The main shaft 13 is externally rotatably set inside the mounting box 1 near the rear end. The front ends of the two locking blocks 18 are inclined. The front ends of the two locking blocks 18 are respectively set inside the rear end of the two locking slots 19. The rear ends of the two pressing blocks 15 are each fitted with a spring 17. The front ends of the two springs 17 are respectively fixedly set inside the front ends of the two fixing blocks 2. Multiple curtain leaves 4 are fixedly set between the two fixing ropes 3. The two winding ropes 8 are respectively fitted inside the multiple curtain leaves 4. An infrared sensor 7 is fixedly set at the front end of the mounting box 1. Both sides of the main shaft 13 are fixedly equipped with winding ropes 8. Both winding ropes 8 are fixedly equipped with connecting blocks 9 at their lower ends. Both connecting blocks 9 have limit grooves 20 on opposite sides. The front end of the base plate 5 is slidably equipped with an unlocking block 6. The rear end of the unlocking block 6 is fixedly equipped with a connecting plate 21. Both sides of the connecting plate 21 are hinged with rotating blocks 23. Both rotating blocks 23 have limit blocks 22 hinged on opposite sides. A compression spring 24 is fixedly installed at the front end of the connecting plate 21. The front end of the compression spring 24 is fixedly installed inside the front end of the base plate 5. The connecting plate 21 is sleeved inside the unlocking block 6 near the rear end. The two limiting blocks 22 are respectively installed on opposite sides inside the two limiting grooves 20. The upper ends of the opposite sides of the two limiting blocks 22 are inclined. The lower ends of the two connecting blocks 9 are installed inside the base plate 5. The upper end of the base plate 5 is installed at the lower end of the mounting box 1. Specifically, before use, fix the device in the corresponding installation position on the room window and ensure that the mounting box 1 and the base plate 5 are horizontally aligned to prevent the curtain slats 4 from shifting during subsequent operation. After installation, connect the external power supply to power the motor 14 and the infrared sensor 7. At this time, the device enters the standby state. When it is necessary to adjust the angle of the curtain 4 to control the light, start the motor 14. The output end of the motor 14 drives the main rotating shaft 13 to rotate inside the mounting box 1. While the main rotating shaft 13 rotates, the spur gear 11 fixed on one side rotates synchronously. Since the spur gear 11 meshes with the half gear 10 on the auxiliary rotating shaft 12, it drives the auxiliary rotating shaft 12 to rotate synchronously inside the mounting box 1. When the auxiliary shaft 12 rotates, the angle ropes connected to both sides of its lower end move synchronously, thereby pulling the fixed block 2 upward. At this time, the slider 16 is fixed inside the fixed block 2. The upward movement of the fixed block 2 is transmitted to all the curtain slats 4 through the fixed rope 3, thereby pulling one side of the curtain slats 4 to rise synchronously, and finally achieving the dimming effect. If it is necessary to pause during the adjustment process, the motor 14 can be turned off. The motor 14 has a self-locking function, which can ensure that the angle of the curtain slats 4 remains unchanged, thus improving the user experience. When the slats 4 need to be retracted or expanded, the motor 14 is started. The motor 14 drives the main shaft 13 to rotate in the forward or reverse direction. When rotating in the forward direction, the winding ropes 8 on both sides of the main shaft 13 will gradually wind up with the shaft. During the winding process, the connecting block 9 is pulled upward. At this time, the limiting block 22 is inserted into the limiting groove 20 of the connecting block 9. The connecting block 9 will synchronously drive the base plate 5 to move upward. The slats 4 will be connected to the base plate 5 through the fixing rope 3, and finally all the slats 4 will be retracted upward. When rotating in the reverse direction, the winding ropes 8 on the main shaft 13 are gradually released. The base plate 5 and the slats 4 slowly unfold downward under their own gravity until they reach the appropriate position. The infrared sensor 7 at the front end of the mounting box 1 is used to detect whether there are any obstructions at the bottom of the slats 4 when they are unfolded, so as to avoid the slats 4 from being damaged by collision with obstructions. When it is necessary to clean the curtain slats 4 or replace the damaged curtain slats 4, first pull the unlocking block 6 at the front end of the base plate 5 forward. The unlocking block 6 drives the connecting plate 21 at the rear end to slide forward inside the base plate 5. During the sliding process of the connecting plate 21, the compression spring 24 is squeezed, causing the compression spring 24 to contract and deform. At the same time, the rotating blocks 23 hinged on both sides of the connecting plate 21 gradually retract with the movement of the connecting plate 21, thereby driving the limiting block 22 to slide relative to each other inside the base plate 5 until the limiting block 22 is completely disengaged from the limiting groove 20 of the connecting block 9. At this time, the base plate 5 can be easily removed from the connecting block 9. Next, regarding the connection between the fixing block 2 and the slider 16, press the pressing block 15 at the front end of the fixing block 2 by hand. The pressing block 15 drives the locking block 18 at the rear end to move backward inside the fixing block 2, while stretching the spring 17. As the locking block 18 moves, it gradually disengages from the locking groove 19 of the slider 16. At this time, the slider 16 can be removed from inside the fixing block 2. After removing all the sliders 16 in sequence according to the above steps, the entire curtain leaf 4 can be slid out from outside the winding rope 8. The connecting block 9 at the lower end of the winding rope 8 is smaller than the through hole in the curtain leaf 4. After maintenance, the slats 4 need to be reinstalled. First, stack all the slats 4 in sequence, ensuring that the guide block at the top of each slat 4 is accurately inserted into the guide groove at the bottom of the next slat 4, ensuring that the slats 4 are stacked neatly. Then, pass the stacked slats 4 through the winding ropes 8 on both sides, so that the winding ropes 8 pass through the through holes on both sides of the slats 4. Then, align one side of the slider 16 with the opening of the fixing block 2 and insert it. Since the upper end of the slider 16 and the lower end of the locking block 18 are both inclined, during the insertion process, the inclined surface at the upper end of the slider 16 will press against the inclined surface at the lower end of the locking block 18, pushing the locking block 18 to slide backward inside the fixing block 2 and press the spring 17. When the slider 16 slides to the set position, the spring 17 rebounds, driving the locking block 18 to reset, so that the locking block 18 is embedded in the locking groove 19, completing the fixing of the slider 16 and the fixing block 2. Finally, insert the lower end of the connecting block 9 into the mounting opening of the base plate 5. Since the upper end of the opposite side of the limiting block 22 is inclined, the lower end of the connecting block 9 will press the inclined surface of the limiting block 22 during the insertion process, pushing the limiting block 22 to retract inward and causing the rotating block 23 to close, the connecting plate 21 to slide forward, and the compression spring 24 to retract. When the connecting block 9 is inserted to the set position, the compression spring 24 rebounds and pushes the connecting plate 21 to move backward. The rotating block 23 then opens, causing the limiting block 22 to embed into the limiting groove 20 of the connecting block 9, thus achieving a stable connection between the connecting block 9 and the base plate 5. At this point, the reinstallation of the curtain leaf 4 is completed, and it can then be used normally. It should be noted that motor 14 is a servo motor 14. Both motor 14 and infrared sensor 7 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. They can be started and controlled by external control equipment. Their functions, specific components and principles are clear to those skilled in the art, so they will not be described in detail here. Each slat 4 has through holes on both sides, allowing the winding rope 8 to slide freely within them, ensuring that the slat 4 rises and falls without jamming. The diameter of the through holes is larger than that of the connecting block 9. Both the winding rope 8 and the fixing rope 3 are made of high-strength nylon rope, and the surface of the winding rope 8 is provided with anti-slip texture to prevent relative sliding between the slat 4 and the winding rope 8. At the same time, rope grooves are provided on both sides of the main rotating shaft 13 inside the mounting box 1. The diameter of the rope grooves matches that of the winding rope 8, ensuring that the winding rope 8 can be neatly arranged in the rope grooves when it is wound up, preventing the winding rope 8 from getting tangled and ensuring the synchronous rise and fall of the slat 4. The spring 17 and the compression spring 24 are both made of stainless steel, which has good fatigue resistance and can prevent rust from affecting the elasticity. All standard parts used in this application can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt mature existing technologies such as bolts, rivets, welding and other conventional methods. Mechanical parts, components and equipment adopt conventional models in the prior art, and circuit connections adopt conventional connection methods in the prior art. Therefore, they will not be described in detail. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.
[0019] Working principle: Before use, install the entire device on the room window. Then, connect the external power supply. When adjusting the angle of the curtain slats 4, the motor 14 starts. Its output end will drive the main shaft 13 to rotate inside the mounting box 1. The rotation of the main shaft 13 will drive the spur gear 11 on one side to rotate synchronously. The rotation of the spur gear 11 will drive the half gear 10 and the auxiliary shaft 12 to rotate inside the mounting box 1. When the auxiliary shaft 12 rotates, the angle ropes on both sides of its lower end will rotate accordingly, thereby driving the fixing block 2 to move upward. This causes the fixing rope 3 to drive all the curtain slats 4 to rise synchronously on one side, causing the curtain slats 4 to deflect and achieve the dimming effect. When it is necessary to raise or lower the curtain slats 4, the motor 14 drives the main shaft 13 to rotate. The winding ropes 8 on both sides of the main shaft 13 are wound or released along with the shaft. When winding, the winding ropes 8 pull the connecting block 9 to move upward. The upward movement of the winding ropes 8 will cause the base plate 5 to gradually move upward, which will then drive the base plate 5 and all the curtain slats 4 to move upward. When releasing, the winding ropes 8 gradually loosen, and the base plate 5 and the curtain slats 4 unfold downward under the action of gravity. To disassemble the curtain slat 4, first pull the unlocking block 6, causing the connecting plate 21 to slide forward inside the base plate 5. The sliding of the connecting plate 21 will compress the compression spring 24, causing the compression spring 24 to contract and drive the rotating block 23 to move. This will cause the limiting block 22 to slide relative to the base plate 5, allowing the limiting block 22 to gradually disengage from the limiting groove 20. Once the limiting block 22 is completely disengaged from the limiting groove 20, the base plate 5 can be removed to disconnect it from the connecting block 9. Then, push the pressing block 15, causing the locking block 18 to slide backward inside the fixing block 2, stretching the spring 17. As the locking block 18 moves, it will gradually disengage from the locking groove 19. Once the locking block 18 is completely disengaged from the locking groove 19, the slider 16 can be removed from the fixing block 2. Then, follow the above steps to remove the slider 16 from the fixing block 2, and the curtain slat 4 can be removed as a whole. When installing the entire curtain slat 4, first stack the curtain slats 4 one by one, so that the guide block at the upper end of the curtain slat 4 is inserted into the guide groove at the lower end of the curtain slat 4. Then, pass the stacked curtain slats 4 through the winding rope 8. Then, insert one side of the slider 16 into the fixed block 2. When the slider 16 is inserted, the inclined surface at the upper end will contact the inclined surface at the lower end of the locking block 18, so that the locking block 18 slides to the rear end inside the fixed block 2. When the slider 16 slides to the set position, the spring 17 rebounds, driving the locking block 18 to reset, so that the locking block 18 is embedded in the locking groove 19, thereby fixing the slider 16. Subsequently, insert the lower end of the connecting block 9 into the base plate 5. When the connecting block 9 is inserted to a certain position, the compression spring 24 rebounds, which will push the limiting block 22 into the limiting groove 20 inside the connecting block 9, thereby connecting the connecting block 9 and the base plate 5.
[0020] 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.
