Description

A honeycomb curtain that can be opened and closed at any position Technical Field

[0001] This invention relates to the field of curtain technology, specifically to a honeycomb curtain that can be opened and closed at any position. Background Technology

[0002] Curtains are becoming increasingly common in people's lives. In my country, curtains are usually made of materials such as cloth or plastic and are placed indoors to beautify the indoor environment, block the outside view, and enhance privacy.

[0003] Current folding curtains have simple functions, with only two operations: raising and lowering the curtains. However, sometimes the indoor light is dim, and when the curtains are raised, excessive light shines into the room, which can be very glaring. Furthermore, the amount of light entering the room cannot be adjusted.

[0004] Therefore, a new type of curtain was developed to solve the above problems. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a honeycomb curtain that can be opened and closed at any position, thus solving the problems mentioned in the background section.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solution: a honeycomb blind that can be opened and closed at any position, comprising a box body, multiple folding shielding components, pull ropes and a bottom plate. The multiple folding shielding components are arranged vertically at equal intervals below the box body, and the bottom plate is located below the folding shielding components. The bottom plate is symmetrically connected to two ends by steel wire one, steel wire two and steel wire three. The three steel wires pass through the multiple folding shielding components and extend into the box body.

[0009] The folding shielding component consists of an upper plate, a lower plate, a side plate one, and a side plate two. The upper plate is located directly above the lower plate. The upper end of the side plate one is hinged to the side of the upper plate, the lower end of the side plate two is hinged to the side of the lower plate, and the lower end of the side plate one is hinged to the upper end of the side plate two. The upper plate, the lower plate, the side plate one, and the side plate two form a movable hexagonal prism.

[0010] The steel wires 1, 2, and 3 pass through the lower plate and the upper plate from bottom to top. Steel wire 1 is connected to multiple metal rings 1 at equal intervals, and steel wire 2 is connected to multiple metal rings 2 at equal intervals. A through hole 1 is opened at the top of the upper plate and relative to steel wire 2, and a through hole 2 is opened at the bottom of the lower plate and relative to steel wire 1.

[0011] When wire one moves upward and wire two moves downward, metal ring one enters the prism through hole two and abuts against the bottom of the upper plate. Metal ring two enters the prism through hole one and abuts against the top of the lower plate. This increases the distance between the upper and lower plates of the prism, causing the prism to unfold and causing adjacent prisms to abut against each other, thus blocking the sunlight.

[0012] As wire one moves downward and wire two moves upward, metal rings one and two, which were originally located inside the prism, move out, causing metal ring one to contact the top of the lower prism and metal ring two to contact the bottom of the upper prism. Metal rings one and two squeeze the prism, flattening and shrinking multiple unfolded prisms. Gaps exist between the prisms, allowing some sunlight to pass through.

[0013] Preferably, a shaft is pivotally connected inside the box, and a large gear and a small gear are sleeved on the shaft. The upper end of a first steel wire is connected to the large gear, the upper end of a second steel wire is connected to the small gear, and the upper end of a third steel wire is connected to the shaft. An arc-shaped groove is opened on the side of the large gear near the small gear, and an electromagnet module is connected in the arc-shaped groove. A magnet is connected on the side of the small gear near the large gear. The magnet slides in the arc-shaped groove, and a spring is connected between the electromagnet module and the arc-shaped groove.

[0014] Preferably, the end of the electromagnet module facing the magnet is the N pole, and the end of the magnet facing the electromagnet module is the N pole. When the electromagnet module is energized, it generates a magnetic field that repels the magnet. When the electromagnet module is de-energized, the spring contracts, causing the electromagnet module to move closer to the magnet.

[0015] When the electromagnet module is energized, the large gear rotates forward by °, winding the first steel wire and causing it to move upward. The small gear rotates backward by °, releasing the second steel wire and causing it to move downward.

[0016] When the electromagnet module is not powered on, the spring contracts, causing the large gear to rotate backward and the small gear to rotate forward, causing the first wire to descend and the second wire to rise.

[0017] Preferably, the pull rope is looped at the right end of the shaft, a base is connected to the top of the inner wall of the box, the large gear and the small gear are located below the base, the base is connected to a base block, the base block is hinged to a connecting rod, a motor is connected to the end of the connecting rod away from the base block, and an auxiliary gear is connected to the motor drive shaft, the auxiliary gear being able to mesh with the large gear.

[0018] Preferably, the base consists of a horizontal part and a vertical part. The top of the horizontal part is welded to the top of the inner wall of the box, and the bottom of the horizontal part is welded to the base block. The vertical part is connected to a crossbar, and an electric actuator is hinged to the bottom of the connecting rod. The lower end of the electric actuator is slidably engaged with the crossbar.

[0019] Preferably, both the large gear and the small gear are half gears. The large gear has two grooves at its bottom. A limiting piece is connected to the bottom of the inner wall of the box. The limiting piece has a transverse section on its side, which can be embedded in the groove.

[0020] Preferably, vibration sensor one and vibration sensor two are connected to the inner wall of the left side of the box. Vibration sensor one is located on the front side of the shaft, vibration sensor two is located on the rear side of the shaft, and a flexible rod is connected to the left end of the shaft. A microcontroller that controls the operation of electronic components is installed inside the box.

[0021] Preferably, the pull rope is provided with balls at equal intervals, the right end of the shaft is provided with a groove that matches the balls, and a limiting block is provided at the right end of the box, with the pull rope passing through the limiting block.

[0022] Preferably, the large gear has a groove one on its outer side, and the small gear has a groove two on its outer side.

[0023] (III) Beneficial Effects

[0024] This invention provides a honeycomb blind that can be opened and closed at any position. It has the following beneficial effects:

[0025] 1. This honeycomb blind, which can be opened and closed at any position, is composed of a box, multiple folding and blocking components, steel wire one, steel wire two, steel wire three, and a base plate. Steel wire one is connected to multiple metal rings, and steel wire two is connected to multiple metal rings. The box contains a large gear and a small gear. By rotating the large gear and the small gear back and forth, steel wire one and steel wire two are raised and lowered, thereby controlling the opening and closing of the folding and blocking components. This achieves the purpose of adjusting and controlling the light transmission of the blind. Moreover, the entire control mechanism is achieved with only one pull cord, saving time and effort, and making it more convenient and quick to use. Attached Figure Description

[0034] This invention provides a honeycomb blind that can be opened and closed at any position, as shown in Figures 1-7. It includes a box body 1, multiple folding and blocking components 2, a pull cord 3, and a base plate 4. The multiple folding and blocking components 2 are arranged vertically at equal intervals below the box body 1. The base plate 4 is located below the folding and blocking components 2. Steel wire 1 5, steel wire 2 6, and steel wire 3 7 are symmetrically welded to both ends of the base plate 4. The three steel wires pass through the multiple folding and blocking components 2 and extend into the box body 1.

[0035] The folding shielding component 2 is composed of an upper plate 21, a lower plate 22, a first side plate 23, and a second side plate 24. The upper plate 21 is located directly above the lower plate 22. The upper end of the first side plate 23 is hinged to the side of the upper plate 21. The lower end of the second side plate 24 is hinged to the side of the lower plate 22. The lower end of the first side plate 23 is hinged to the upper end of the second side plate 24. The upper plate 21, the lower plate 22, the first side plate 23, and the second side plate 24 form a movable hexagonal prism.

[0036] Steel wire 1 5, steel wire 2 6, and steel wire 3 7 pass through the lower plate 22 and the upper plate 21 from bottom to top. Steel wire 1 5 has multiple metal rings 1 51 welded at equal intervals, and steel wire 2 6 has multiple metal rings 2 61 welded at equal intervals. The upper plate 21 has a through hole 1 211 at the top and opposite to steel wire 2 6, and the lower plate 22 has a through hole 2 221 at the bottom and opposite to steel wire 1 5.

[0037] When wire 5 moves upward and wire 6 moves downward, metal ring 51 enters the prism through hole 221 and abuts against the bottom of upper plate 21, while metal ring 61 enters the prism through hole 211 and abuts against the top of lower plate 22. This increases the distance between upper plate 21 and lower plate 22, causing the prism to unfold and causing adjacent prisms to abut against each other, thus blocking sunlight.

[0038] When wire 5 moves downward and wire 6 moves upward, metal rings 51 and 61, which were originally located inside the prism, move out, so that metal ring 51 contacts the top of the lower prism and metal ring 61 contacts the bottom of the upper prism. Metal rings 51 and 61 squeeze the prism, flattening and shrinking multiple unfolded prisms. There are gaps between the prisms, allowing some sunlight to pass through.

[0039] A shaft 8 is pivotally connected inside the housing 1, and a large gear 11 and a small gear 12 are fitted onto the shaft 8. The large gear 11 and the small gear 12 can rotate on the shaft 8.

[0040] The upper end of wire 15 is welded to the large gear 11, the upper end of wire 26 is welded to the small gear 12, and the upper end of wire 37 is welded to the shaft 8. An arc-shaped groove 112 is provided on the side of the large gear 11 near the small gear 12. An electromagnet module 113 is fixedly installed in the arc-shaped groove 112. A magnet 122 is fixedly installed on the side of the small gear 12 near the large gear 11. The magnet 122 slides in the arc-shaped groove 112. A spring 114 is fixedly installed between the electromagnet module 113 and the arc-shaped groove 112.

[0041] The end of the electromagnet module 113 facing the magnet 122 is the N pole, and the end of the magnet 122 facing the electromagnet module 113 is also the N pole. When the electromagnet module 113 is energized, it generates a magnetic field that repels the magnet 122. When the electromagnet module 113 is de-energized, the spring 114 contracts, causing the electromagnet module 113 to move closer to the magnet 122.

[0042] When the electromagnet module 113 is powered on, the large gear 11 rotates forward 90°, and the large gear 11 winds the steel wire 5, causing the steel wire 5 to move upward. The small gear 12 rotates backward 90°, and the small gear 12 releases the steel wire 6, causing the steel wire 6 to move downward.

[0043] When the electromagnet module 113 is not powered on, the spring 114 contracts, causing the large gear 11 to rotate backward and the small gear 12 to rotate forward, causing the steel wire 5 to descend and the steel wire 6 to rise.

[0044] The second steel wire 6 is longer than the first steel wire 5, and part of the second steel wire was originally wrapped around the pinion 12. When the pinion 12 releases the second steel wire 6, the weight of the second metal ring 61 causes the second steel wire 6 to fall, thereby causing the lower plate to be subjected to a downward force.

[0045] The pull rope 3 is attached to the right end of the shaft 8. A base 9 is welded to the top of the inner wall of the box 1. The large gear 11 and the small gear 12 are located below the base 9. A base block 91 is welded to the base 9. A connecting rod 92 is hinged to the base block 91. A motor 93 is fixedly installed at the end of the connecting rod 92 away from the base block 91. An auxiliary gear 94 is fixedly installed on the drive shaft of the motor 93. The auxiliary gear 94 can mesh with the large gear 11.

[0046] The base 9 consists of a horizontal section and a vertical section. The top of the horizontal section is welded to the top of the inner wall of the box 1, and the bottom of the horizontal section is welded to the base block 91. A crossbar 95 is welded to the vertical section. An electric actuator 96 is hinged to the bottom of the connecting rod 92, and the lower end of the electric actuator 96 slides in engagement with the crossbar 95. The retraction of the electric actuator 96 commands the auxiliary gear 94 to mesh with the large gear 11.

[0047] Both the large gear 11 and the small gear 12 are half gears. The large gear 11 has two grooves 115 at its bottom. A limiting piece 13 is connected to the bottom of the inner wall of the housing 1. The limiting piece 13 has a transverse section on its side, which can be inserted into the grooves 115. The limiting piece 13 limits the rotation range of the large gear 11, preventing the large gear 11 from disengaging from the auxiliary gear 94.

[0048] Vibration sensor 14 and vibration sensor 25 are fixedly installed on the inner wall of the left side of the box 1. Vibration sensor 14 is located in front of the shaft 8, and vibration sensor 25 is located in rear of the shaft 8. A flexible rod 81 is fixedly installed on the left end of the shaft 8. The shaft 8 will hit the sensor during rotation.

[0049] A microcontroller that controls the electronic components is fixedly installed inside the housing 1. Wires are connected to the outside of housing 1, electrically connecting to the electronic components and to the indoor electrical circuit. Since this is a standard technical method, it will not be described in detail.

[0050] The pull rope 3 is provided with balls 31 at equal intervals, and the pull rope and the balls 31 are integrally formed.

[0051] The right end of the shaft 8 has a groove 82 that mates with the ball bearing 31, and the right end of the box 1 has a limiting block 10, through which the pull rope 3 passes. The ball bearing 31 mates with the groove 82, allowing the shaft 8 to rotate when the pull rope 3 is pulled.

[0052] The outer side of the large gear 11 has a wire groove 111, and the outer side of the small gear 12 has a wire groove 121.

[0053] The first stage of operation: Grasp the front of the pull cord 3 and pull it downwards slightly, causing the shaft 8 to rotate forward. The flexible rod 81 first strikes the vibration sensor 14, which transmits a signal to the microcontroller. The microcontroller then powers on the electromagnet module 113. This causes the steel wire 5 to rise and the steel wire 6 to fall, unfolding the entire folding curtain component 2. At this point, the folding curtain component 2 works together to form a single curtain, fully opening to block sunlight from entering the room.

[0054] The second stage of operation: With the curtain fully extended, pulling the pull cord 3 reverses the direction, causing the shaft 8 to rotate backward. The shaft 8 strikes the vibration sensor 15. The vibration sensor 15 transmits information to the microcontroller, which then controls the electromagnet module 113 to de-energize. The spring contracts, pulling the electromagnet module 113 and the magnet 122. This causes the large gear 11 and the small gear 12 to move in the opposite direction, lowering the steel wire 5 and raising the steel wire 6, thus retracting the folding blinding component 2 and allowing some sunlight to enter the room, placing the entire curtain in a semi-closed state.

[0055] The third stage of operation: With the curtains partially obscured, the shaft 8 continues to rotate backward. The flexible rod 81 first strikes vibration sensor 2 15 and then vibration sensor 1 14, causing the microcontroller to stop all electronic components. The rotating rod 8 winds steel wire 3 7, at which point steel wire 1 5 and steel wire 2 6 are in a slack state. Steel wire 3 7 drives the base plate 4 to rise, causing the originally folded curtain components 2 to stack together, thus raising the entire curtain.

[0056] The purpose of setting up the auxiliary gear 94 is as follows: As shown in Figure 4, the arc-shaped groove 112 is relatively long, and the elasticity of the spring 114 will gradually deteriorate due to repeated stretching during use. In the second stage, the auxiliary gear 94 drives the large gear 11 to rotate, sharing some of the workload of the spring 114. This prevents the spring from deteriorating and being unable to pull the large gear 11 and the small gear 12 closer together.

[0057] In summary, this honeycomb blind, which can be opened and closed at any position, is composed of a box body 1, multiple folding and blocking components 2, steel wires 5, 6, and 7, and a base plate 4. Steel wire 5 is connected to multiple metal rings 51, and steel wire 6 is connected to multiple metal rings 61. The box body 1 contains a large gear 11 and a small gear 12. By rotating the large gear 11 and the small gear 12, the rise and fall of steel wires 5 and 6 are controlled, thereby controlling the opening and closing of the folding and blocking components 2. This achieves the purpose of adjusting the light transmission of the blind. Furthermore, the entire control mechanism is achieved using only a single pull cord 3, saving time and effort, and making it more convenient and efficient to use.
