Description

Technical Field

[0001] The present invention belongs to the technical field of electric curtains, and particularly relates to a suspended electric curtain system for a triangular curtain wall. Background Art

[0002] At present, suspended curtains are relatively mature in the market, and both electric and manual curtains have a large market scale. However, when installing existing suspended curtains, the upper part of the window needs to be horizontal for installation; for windows with a triangular shape at the top of the window, existing suspended curtains are generally difficult to apply. It is difficult to block the triangular area above the window, resulting in a problem of mismatch between the curtain and the electric connection. Currently, for windows with a triangular area at the top, the solution is mostly to set a horizontal suspended curtain on the back side of the triangular curtain wall to cover the entire triangular area. However, this method requires sufficient installation space on the back side of the triangular curtain wall. However, since existing glass curtain walls are often installed prior to the curtains, it is difficult to install curtains on many existing triangular curtain walls.

[0003] Therefore, designing a suspended electric curtain system that can be suitable for installation inside the window frame and can block the triangular area at the top has become a problem to be solved. Summary of the Invention

[0004] In order to solve the above problems existing in the prior art, the present solution provides a suspended electric curtain system for a triangular curtain wall.

The central gear is in transmission connection with the output shaft of the rolling curtain motor. The transmission gear is engaged between the toothed ring and the central gear.

[0011] As an alternative or supplement to the above structure: The central gear is coaxially connected with a driving bevel gear. The rope winding disc is coaxially connected with a driven bevel gear. The driving bevel gear is engaged with the driven bevel gear to control the rope winding disc to wind up the hanging rope when the driving bevel gear rotates.

[0012] As an alternative or supplement to the above structure: A battery and a circuit board are fixed on the fixing frame. The battery supplies power to the driving mechanism under the control of the circuit board to enable the drum to wind up or lower the curtain, and at the same time enable the rope winding disc to wind up or release the hanging rope.

Specific implementation manner

[0025] Next, the technical solutions in this embodiment will be clearly and completely described in conjunction with the accompanying drawings. The described embodiments are only a part of the embodiments, rather than all of them. Based on the embodiments in this solution, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this solution.

[0026] As Figures 1 to 5 shown, this embodiment designs a suspended electric curtain system for a triangular curtain wall, including components such as a rolling curtain device 4, a fixed box frame 3, and a rolling curtain track 6.

[0027] The fixed box frame 3 is a long box structure with an open bottom. A first guide wheel 31 is respectively arranged at both ends of the fixed box frame 3. The curtain cloth 2 can be hung below the fixed box frame 3. When the fixed box frame 3 is installed, the fixed box frame 3 can be fixed to the hypotenuse at the top of the window, so as to block the triangular area at the top of the window.

[0028] Roller shutter tracks 6 are respectively arranged on the left and right sides of the triangular curtain wall; a rail groove 61 is arranged on the roller shutter track 6, the rail grooves 61 of the two roller shutter tracks 6 face each other, and the end of the roller shutter device 4 can extend into the rail groove 61, so as to use the rail groove 61 to guide and limit the lifting of the roller shutter device 4. The upper end and the lower end of the roller shutter track 6 are respectively provided with track end caps 62, and the track end caps 62 can prevent the end of the roller shutter device 4 from falling off the roller shutter track 6.

[0029] The roller shutter device 4 includes components such as a fixed frame 43, a drum 41, end caps 42, a rope winding disc 471 and a power mechanism.

[0030] The drum 41 is in a tubular shape, and a curtain cloth 2 is connected between the drum 41 and the fixed box frame 3; when the drum 41 rotates, the curtain cloth 2 can be wound onto the drum 41, so as to realize the storage or release of the curtain cloth 2.

[0031] One end cap 42 is respectively arranged at both ends of the drum 41, and the end cap 42 is in sliding fit with the roller shutter track 6; specifically, a limiting head 421 is arranged on the side end face of the end cap 42, the limiting head 421 is in a flat sheet structure, and the limiting head 421 is inserted into the roller shutter track 6 during use, so that the limiting head 421 can be in sliding fit with the rail groove 61 on the roller shutter track 6, thereby preventing the end cap 42 from rotating. The brim of the end cap 42 turns outwards radially, so as to form a brim extending radially outwards, and the brim can limit the curtain cloth 2, thereby preventing the curtain cloth 2 from wrapping the end cap 42.

[0032] Rope winding discs 471 are arranged in both end caps 42. The hanging rope 5 on one rope winding disc 471 winds around two first guide wheels 31 on the fixed box frame 3 and then is connected to the other rope winding disc 471. When the rope winding disc 471 rotates, the hanging rope 5 can be wound by the rope winding disc 471, so as to pull the roller shutter device upwards or downwards. Thus, the lifting control of the rope winding disc 471 is realized. In addition, when a second guide wheel is coaxially arranged at the end of the first guide wheel 31, the second guide wheel can rotate freely relative to the first guide wheel, and a third guide wheel can be arranged in the end cap of the roller shutter device, and the hanging rope can successively pass around the first guide wheel, the third guide wheel and the second guide wheel.

[0033] The fixed frame 43 is arranged in the drum 41 and is fixedly connected to the end cap 42. Specifically, the fixed frame 43 can include a transverse hollow tube and a longitudinal hollow tube. The two ends of the longitudinal hollow tube are fixedly connected to the inner wall of the end cap 42, so that the longitudinal hollow tube can be fixed in the end cap 42. The transverse hollow tube is arranged in the drum 41, and the end of the transverse hollow tube is vertically and fixedly connected to the end of the longitudinal hollow tube, so that the fixed frame 43 can be fixed to the end cap 42.

[0034] A motor mechanism is provided at the left and right ends of the drum 41. The motor mechanism can drive the rope reel 471 and the drum 41; when the rope reel 471 is driven to rotate by the corresponding power mechanism, the rope reel 471 can synchronously reel in the hanging rope 5; when the drum 41 is driven to rotate by the corresponding power mechanism, the drum 41 can roll up the curtain 2 or lower the curtain 2.

[0035] The power mechanism includes a roller shutter motor 49 and a planetary gear assembly 48, wherein the planetary gear assembly 48 includes a gear ring 481, a central gear 482 and a transmission gear 483. The transverse hollow tube is fixedly connected to the roller shutter motor 49, and the transverse hollow tube passes through the center of the central gear 482, so that the central gear 482 can rotate around the transverse hollow tube. The gear ring 481 is fixed to the inner wall of the reel 41, the central gear 482 is connected to the output shaft of the roller shutter motor 49, and the transmission gear 483 is meshed between the gear ring 481 and the central gear 482. When the central gear 482 rotates under the drive of the roller shutter motor 49, the rotation of the reel 41 can be controlled by the transmission gear 483 and the gear ring 481.

[0036] The central gear 482 is coaxially connected with the active bevel gear 473, and the active bevel gear 473 is rotatably sleeved outside the transverse hollow tube. The rope winding drum 471 is coaxially connected with the driven bevel gear 472, and the driven bevel gear 472 is rotatably sleeved outside the longitudinal hollow tube. The rope winding drum 471 can also be rotatably sleeved outside the longitudinal hollow tube. The active bevel gear 473 is meshed with the driven bevel gear 472. When the active bevel gear 473 rotates synchronously with the central gear 482, the rope winding drum 471 can be controlled to rotate, thereby winding up the hanging rope 5.

[0037] A battery 44 and a circuit board 45 are fixed on the fixing frame 43. The battery 44 supplies power to the driving mechanism under the control of the circuit board 45, so that the reel 41 can reel in or lower the curtain 2, and the rope reel 471 can reel in or release the hanging rope 5. The circuit board 45 can also be connected to the mains through a wire to charge the battery 44, and the wire can be routed through the longitudinal hollow tube and the transverse hollow tube. A wireless receiving module can be set on the circuit board 45 to facilitate remote control lifting and lowering using a remote controller.

[0038] When the power mechanism drives the rope winding disk 471 and the drum 41 to rotate synchronously, since the diameter of the rope winding disk 471 remains basically unchanged after the hanging rope 5 is wound up, while when the curtain fabric 2 is wound onto the drum 41, the diameter of the drum 41 will become larger and larger. Therefore, it is difficult for the two to be synchronized. To solve this problem, the driving bevel gear 473 and the driven bevel gear 472 can be adjusted, and the gear ratio of the planetary gear assembly 48 can also be adjusted, so that the winding length of the hanging rope 5 is greater than the length of the curtain fabric 2 wound when the drum 41 rotates. Thus, the curtain fabric 2 can be loosely wound outside the drum 41. Even after the curtain fabric 2 is completely wound and the outer diameter of the drum 41 increases, the loose curtain fabric 2 can be used for tightening, so as to achieve the effect of length compensation.

[0039] A locking assembly 46 is further provided inside the drum 41. The locking assembly 46 includes components such as a locking rod 462, a rack 461, a locking motor 464 and a locking disk 463. The locking disk 463 is fixedly connected to the drum 41. A number of locking holes are provided on the drum 41. The locking rod 462 is slidably arranged on the fixed frame 43 and can be inserted into the locking holes to lock the drum 41. The rack 461 is slidably arranged on the fixed frame 43 and is fixedly connected to the locking rod 462. The gear on the output shaft of the locking motor 464 meshes with the rack 461. Locking disks 463 are arranged on the inner sides of both ends of the drum 41. The gear meshes with the two racks 461. Each rack 461 is fixedly connected to a locking rod 462, and each locking rod 462 is used to lock a locking disk 463. When the locking motor 464 rotates, it can control the lateral movement of the rack 461, so that the locking rod 462 can be inserted into the locking disk 463, thereby using the locking rod 462 to lock the relative positions of the locking disk 463 and the drum 41. After the power mechanism stops rotating, the winder will fall due to gravity.

[0040] The above embodiments are merely examples for clear illustration and not limitations on the implementation manners; it is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present technology.
