Description

A honeycomb curtain with a lower drive unit Technical Field

[0001] This invention relates to a honeycomb curtain with a drive unit located below. Background Technology

[0002] Electric honeycomb blinds are a type of curtain system that opens and closes automatically via a motor. Their internal structure features a honeycomb pleated design, providing excellent heat insulation and sound insulation.

[0003] In existing motorized honeycomb blinds, the battery, motor, and cord reel are all installed in the upper beam. The lower beam is raised and lowered by the motor driving the cord reel. Although lithium batteries have a long lifespan, their capacity gradually decreases over time. When the battery is low or needs replacement, the user must charge or replace it. Since the battery, motor, and other critical components are located in the upper beam at the top of the blind, the user must climb above the window to charge or replace the battery. This process is not only extremely inconvenient but also poses a potential safety hazard. Furthermore, with frequent use of motorized honeycomb blinds, the pull cord in the cord reel may gradually stretch due to friction and tension. This not only affects the overall appearance of the blind, making the lower beam appear uneven, but the tilted lower beam can also cause it to jam against the side rail during movement, hindering normal opening and closing.

[0036] (Example 1)

[0037] As shown in Figures 4-7, the honeycomb blind with the drive device positioned below in this embodiment includes a fixed beam 1, a movable beam 2, a curtain fabric 3 installed between the fixed beam 1 and the movable beam 2, and a winding rope 4 threaded through the curtain fabric. The movable beam 2 is equipped with a drive device 5 and a winding rope 6, with the output end of the drive device 5 connected to the winding rope 6. A leveling device 7 is provided on the movable beam 2. One end of the winding rope 4 is wound around the winding rope 5, and the other end passes over the fixed beam 1 and connects to the leveling device 7. The leveling device 7 adjusts the balance of the movable beam 2. In this embodiment, the fixed beam 1 is the upper beam, and the corresponding movable beam 2 is the lower beam. In other embodiments, the fixed beam 1 can be the lower beam, and the movable beam 2 can be the upper beam; in this case, the movable beam 2 needs to cooperate with the side rail track.

[0038] The drive device 5 uses a tubular motor. The moving beam 2 has a left end cover 8 and a right end cover 9 fixed to its two ends respectively. The tubular motor cooperates with the left end cover 8, and the leveling device 7 is located in the right end cover 9. A rotating shaft 10 is installed in the moving beam 2. One end of the rotating shaft 10 is sleeved on the output end of the tubular motor, and the other end of the rotating shaft 10 is rotatably connected to the right end cover 9. A circular boss is provided on the side of the right end cover 9 facing the rotating shaft 10, and the rotating shaft 10 is sleeved on the circular boss. A rope winder 6 is sleeved on the rotating shaft 10. The outer surface of the rotating shaft 10 can be a hexagonal or octagonal bar, etc. The inner surface of the rope winder 6 has the same shape as the outer surface of the rotating shaft 10. When the tubular motor drives the rotating shaft 10 to rotate, it can drive the rope winder 6 to rotate synchronously. A slot is provided on the fixed end of the tubular motor, and a retaining shaft that cooperates with the slot is provided on the left end cover 8. When the left end cover 8 is fixed to the moving beam 2, the retaining shaft is embedded in the slot to fix the tubular motor. The right end cover 9 includes an end cover seat and a cover plate, with an inner cavity formed between the end cover seat and the cover plate. The leveling device 7 is installed in the inner cavity, and the cover plate is engaged with the end cover seat.

[0039] The leveling device 7 includes a second leveling seat 7-5, a second winding shaft 7-6, and a second elastic element 7-7. The second winding shaft 7-6 is rotatably mounted in the second leveling seat 7-5. The other end of the winding rope 4 is wound around the second winding shaft 7-6. The second leveling seat 7-5 has a through hole that mates with the end of the second winding shaft 7-6. The second elastic element 7-7 prevents the end of the second winding shaft 7-6 from disengaging from the through hole. When the end of the second winding shaft 7-6 is located in the through hole, the second winding shaft 7-6 and the second leveling seat 7-5 are circumferentially fixed. The through hole can be a non-circular hole such as a hexagonal or octagonal hole. The end of the second winding shaft 7-6 matches the shape of the through hole, or the end of the second winding shaft 7-6 is keyed to the through hole. Any structure that can achieve circumferential fixation between the second winding shaft 7-6 and the second leveling seat 7-5 is acceptable. In this embodiment, the second leveling seat 7-5 can be an end cap seat.

[0040] The second elastic element 7-7 is disposed between the second winding shaft 7-6 and the second leveling seat 7-5. A second locking platform 7-6-1 is provided on the second winding shaft 7-6. A horizontal plate 7-5-1 that mates with the second locking platform 7-6-1 is provided inside the second leveling seat 7-5. The second winding shaft 7-6 passes through the horizontal plate 7-5-1. The second elastic element 7-7 is adapted to clamp the second locking platform 7-6-1 onto the horizontal plate 7-5-1. When the second elastic element 7-7 clamps the second locking platform 7-6-1 onto the horizontal plate 7-5-1, the end of the second winding shaft 7-6 is located in the through hole. The second elastic element is a compression spring.

[0041] A Type-C port is located on the left end cover 8, which can simultaneously support charging, connecting external solar panels, and detecting and updating motor control software.

[0042] The movable beam 2 includes a base 2-1 and a panel 2-2. The base 2-1 has an opening on one side, and the panel 2-2 is located at the opening. The panel 2-2 is rotatably connected to the base 2-1. Of course, in this embodiment, since the tubular motor is located at the end of the movable beam 2, the movable beam 2 can also be made as a single piece. When maintenance of the motor is required, the tubular motor can be removed by removing the left end cover 8.

[0043] In this embodiment, one end of the rope 4 is wound around the rope winder 6, and the other end is wrapped around the fixed beam 1 and fixed to the second winding shaft 7-6. When the moving beam 2 is unbalanced, a tool (such as a screwdriver, the end of the second winding shaft 7-6 is provided with a groove-like structure that cooperates with the tool) is used to poke the end of the second winding shaft to disengage it from the through hole. The second winding shaft 7-6 is rotated by rotating the tool to adjust the unwinding or winding of the rope 4, so as to achieve the left and right balance of the moving beam 2. After the adjustment is completed, the poke of the second winding shaft 7-6 is stopped, so that the end of the second winding shaft 7-6 returns to the through hole and is locked.

The other end of the first winding shaft 7-2 is provided with a first retaining platform 7-2-1, and the first elastic element 7-4 is disposed between the first retaining platform 7-2-1 and the first leveling seat 7-1. The first elastic element 7-4 is a tension spring, and the first retaining plate 7-2-1 can be a retaining spring or integrally formed with the winding shaft 7-2.

[0047] One end of the coiled rope 4 is fixed on the first winding shaft 7-2. When the moving beam 2 is unbalanced, open the panel 2-2, pull the first leveling knob 7-3, and after the first leveling knob 7-3 is disengaged from the slot 7-1-1, rotate the first winding shaft 7-2 to adjust the unwinding or rewinding of the coiled rope 4 to achieve left and right balance of the moving beam 2. After adjustment, release the first leveling knob 7-3 so that it is inserted into the slot 7-1-1 and locked in place.

[0048] Of course, the leveling device 7 in this embodiment can be installed in the end cover 11 by extending the pull rope, or the leveling device 7 in embodiment 1 can be selected.
