Technical Field
[0001] This utility model relates to the field of curtain technology, specifically to an intelligent integrated curtain. Background Technology
[0002] Traditional blind structures, especially Venetian blinds, suffer from several issues affecting their performance and lifespan. Firstly, the motor components in traditional Venetian blinds often lack effective control over the roller speed, typically operating at a fixed speed. This prevents users from flexibly adjusting the blind's opening and closing speed according to their needs, resulting in a poor user experience. Secondly, the lack of an effective guiding structure during slat opening and closing leads to unstable slat paths, prone to jamming and tangling. This not only affects the normal use of the blinds but can also damage the slats, shortening their overall lifespan. Furthermore, when external loads such as strong winds act on the slats, traditional Venetian blinds lack a corresponding load-bearing structure to distribute the load. This causes the load to be directly transmitted to the pull cord, resulting in prolonged friction or collision between the cord and the roller. Over time, the pull cord is prone to wear and even breakage, significantly reducing its lifespan and increasing maintenance costs and replacement frequency. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides an intelligent integrated curtain that solves the problems of traditional Venetian blinds, such as the inability to control the roller speed of the motor assembly, unstable slat opening and closing, and the fact that when external loads are applied to the slats, the load is transmitted to the pull cord, causing the pull cord to rub or collide with the roller for a long time, thus reducing the lifespan of the pull cord.
[0004] To achieve the above objectives, this utility model provides an intelligent integrated curtain, including a beam and a bottom frame. A curtain body is disposed between the bottom frame and the beam. The curtain body is composed of several stacked slats and ladder ropes for connecting the slats. A pull rope is disposed on the bottom frame. An operating cavity is hollowed out in the beam. A roller and a motor assembly for driving the roller to rotate axially and whose rotation speed can be adjusted are disposed in the operating cavity. A slot is provided on the bottom wall of the beam for communicating with the operating cavity to allow the slats and pull rope to be placed into the operating cavity. The end of the pull rope is wound around the roller to realize the winding or unfolding of the pull rope when the roller rotates. The motor assembly cooperates with the roller to realize the unfolding or stacking of the slats. A guide structure is provided on the beam to guide the winding and unfolding path of the slats when the slats are unfolded or stacked, and a load-bearing structure is provided to prevent the load from being concentrated on the pull rope and roller when external loads are applied to the slats.
[0005] The advantage of adopting the above technical solution is that the motor assembly in this utility model has the ability to precisely control the speed of the reel, achieving speeds of 20 rpm, 30 rpm, and 40 rpm. The adjustable rotation speed allows for flexible adjustment of the blind's opening and closing speed in different usage scenarios. Even when the motor is not running or fails to start due to malfunction, the user can still manually pull the bottom frame to unfold or stack the slats, ensuring the blinds can be used normally under any circumstances. This avoids the embarrassing situation of the blinds failing due to motor problems, greatly improving the product's reliability and practicality. To achieve the above effects, the motor assembly can use a stepper motor, a motor with an overrunning clutch, or an AC asynchronous motor. The guiding structure in the above technology effectively guides the opening and closing path of the slats when several slats are unfolded or stacked, ensuring the stability of the blind's opening and closing process and preventing jamming or tangling between slats, thus extending the blind's service life. Simultaneously, the load-bearing structure prevents the load from concentrating on the pull cord and roller when external loads are applied to the slats, reducing damage caused by prolonged friction or collision between the pull cord and roller, further improving the pull cord's service life and reducing product maintenance costs.
[0006] The present invention further includes: several guide grooves are provided on the inner walls of both sides of the slot along the length of the beam, and a roller is rotatably arranged in the guide groove. The roller partially extends out of the guide groove into the slot and forms a contact part for contacting the side wall of the blade. The roller is the guide structure.
[0007] The advantages of adopting the above technical solution are: the rollers rotating in the guide grooves set on the inner walls of both sides of the slot along the length of the beam play a key guiding role in the use of the venetian blind. When the blades are laid out or stacked, the contact parts between the side walls of the blades and the rollers interact. Since the rollers can rotate freely, the friction force experienced by the blades when they move is greatly reduced. Compared to Venetian blinds without roller guidance, the slats move more smoothly along the slots, avoiding jamming caused by excessive friction between the slats and the inner wall of the slots. This results in a smoother operation and improved ease of use. Multiple rollers evenly distributed on both sides of the slots provide comprehensive, multi-node guidance for the slat movement, effectively preventing slat deviation or tilting during opening and closing. The rollers transform the sliding friction between the slats and the inner wall of the slots into rolling friction, significantly reducing wear and tear. This minimizes wear during movement, allowing the slats to maintain good physical properties and appearance, extending their lifespan. Furthermore, the more stable slat movement reduces additional strain and wear on connecting ropes and pull cords, indirectly extending the overall lifespan of the Venetian blind system and lowering maintenance costs and replacement frequency for users.
[0008] The present invention further comprises: bearing grooves are provided on both sides of the inner wall of the slot along the length of the beam; the bearing structure includes two bearing plates arranged opposite to each other, the two bearing plates are respectively arranged in two bearing grooves; the bearing plates partially extend out of the bearing groove into the slot and form a force-bearing part for contacting the outer wall of the blade when the blade is subjected to external load; the outer peripheral wall of the force-bearing part is connected to the bearing plate with a smooth arc surface; an electric push rod assembly is provided in the bearing groove for driving the bearing plate to slide in the bearing groove so that the force-bearing part extends out of the bearing groove or retracts into the bearing groove.
[0009] The advantages of adopting the above technical solution are as follows: When the blades are subjected to external loads, such as strong winds or accidental impacts, the load-bearing plate's stress-bearing part quickly comes into play. Because the stress-bearing part is in contact with the outer wall of the blade, it can promptly absorb and disperse the external force on the blade, preventing the load from concentrating on the blade. This not only effectively protects the blades themselves from damage by excessive external forces, ensuring the integrity of the blade structure, but also prevents excessive stretching of the ladder ropes connecting the blades due to excessive local stress on the blades, extending the service life of the ladder ropes and ensuring the stability of the entire curtain structure. Furthermore, the electric push rod assembly installed in the load-bearing groove gives the load-bearing structure flexible adjustment capabilities. Under normal use, the load... Driven by an electric actuator assembly, the load-bearing part of the carrier plate extends slightly beyond the load-bearing groove, ready to withstand potential external loads. The outer wall of the load-bearing part connects smoothly to the carrier plate via a curved surface. This design significantly reduces friction between the blades and the load-bearing structure. During frequent blade deployment, stacking, and the application of external loads, the smooth curved surface effectively reduces wear on the blade's outer wall, maintaining its appearance and physical properties. Simultaneously, it reduces the risk of blade damage due to friction, indirectly reducing additional wear on other related components such as the pull cord and roller, thereby lowering the overall maintenance cost of the venetian blind system and improving product reliability and lifespan. The electric actuator assembly described above is existing technology; therefore, its structure, function, and dimensions will not be elaborated upon further.
[0010] The present invention further includes: a proximity sensor is provided in the operating cavity, the detection end of the proximity sensor is located near the pull rope, and the proximity sensor is communicatively connected to the electric push rod assembly.
[0011] The advantages of adopting the above technical solution are as follows: When the blade is subjected to external load impact and shakes, the pull rope will swing significantly. The proximity sensor, with its detection end close to the pull rope, can sensitively detect the changes in the pull rope's approach and departure at a certain amplitude or frequency. Once the frequent approach of the pull rope is detected, the proximity sensor will quickly transmit the signal to the electric push rod assembly. Upon receiving the signal, the electric push rod will immediately start, driving the bearing plate to move rapidly, so that the force-bearing part quickly contacts the outer wall of the adjacent blade. The rapid response process is completed in a very short time, which can timely limit the excessive shaking of the blade in the slot, providing reliable immediate protection for the blade and effectively reducing the risk of blade damage due to excessive shaking amplitude. By limiting the blade, firstly, the load borne by the blade can be transferred to the force-bearing part, and secondly, the blade can be prevented from causing the pull rope to shake excessively. Through the coordinated work of the proximity sensor and the electric push rod assembly, the excessive shaking of the pull rope caused by the blade is effectively avoided. Excessive shaking of the rope often aggravates the friction and wear between it and the reel and other components, which will significantly shorten the service life of the pull rope in the long run. This design stabilizes the movement of the pull cord, reduces unnecessary wear, and extends its lifespan. Simultaneously, the effective limitation of the blades reduces fatigue damage caused by excessive swaying, extending their lifespan and thus lowering the maintenance costs of the entire Venetian blind system, improving overall product durability. The innovative combination of the proximity sensor and electric actuator assembly in this technology endows the Venetian blind product with intelligent features. This intelligence is reflected in the product's ability to automatically sense changes in the external environment (pulling cord swaying due to load impact on the blades) and automatically make corresponding adjustments based on the sensing results (driving the load-bearing plate to limit blade swaying). Compared to traditional Venetian blinds, this significantly improves the product's automation level and user experience. For consumers seeking a smart lifestyle, Venetian blinds with such intelligent load-bearing protection functions are more attractive, helping to enhance the product's competitiveness in the market and further expand its market share. The proximity sensor in the above technology is existing technology; therefore, its detection principle, structure, and communication connection method with the electric actuator assembly will not be elaborated further.
[0012] The present invention further includes: a spring seat is provided in the operating cavity, the spring seat has a through hole for the winding shaft to pass through, and a torsion spring is provided between the through hole and the winding shaft.
[0013] The advantages of adopting the above technical solution are: the spring seat in the operating cavity and the torsion spring between the perforation and the roller give the Venetian blind slats the characteristic of automatic reset. When the user manually pulls the bottom frame to unfold or stack the slats, releasing the bottom frame will cause the torsion spring to drive the roller to rotate in the opposite direction due to its own elastic restoring force. This rotation causes the pull cord to rewind or unfold in the opposite direction, thereby realizing that the slats automatically return to their initial position. The automatic reset function greatly improves the convenience of user operation, eliminating the need for the user to manually adjust the slats back to their original position. It is especially suitable for scenarios where Venetian blinds are used frequently, saving the user's operation time and effort.
[0014] The present invention further includes: an installation groove is provided on the top wall of the beam along the length of the beam, the installation groove is connected to the operating cavity, the installation groove is connected to the two side walls of the beam and forms a sliding opening, and a sealing plate for closing the installation groove is installed at the opening of the installation groove.
[0015] The advantages of adopting the above technical solution are as follows: The mounting groove opened along the length of the top wall of the structure, which connects to the operating cavity and forms sliding openings on both side walls, greatly facilitates the installation and maintenance of internal components. When installing components such as motor assemblies and rollers, the components can be slid into the mounting groove from the side of the beam through the sliding openings, and then easily placed into the operating cavity for installation and fixation. Similarly, when maintaining or replacing internal components, the components can be easily removed using the sliding openings without the need for large-scale disassembly of the entire beam structure, saving installation and maintenance time and labor costs, and improving work efficiency. The sealing plate installed at the opening of the mounting groove can effectively seal the mounting groove, providing good protection for the motor assemblies, rollers, pull ropes, and other components inside the operating cavity. The sealing plate can prevent external pollutants such as dust, moisture, and debris from entering the operating cavity, avoiding these pollutants from causing corrosion, wear, or malfunction of the internal components. Especially when using Venetian blinds in environments with high dust or humidity, the protective effect of the sealing plate can significantly extend the service life of the internal components, ensuring that the Venetian blinds are always in good working condition.
