Description

A rolling shutter system for insulating glass Technical Field

[0001] The present invention relates to the field of building doors and windows, in particular to insulating glass with a double-layer glass structure and a built-in roller shutter, specifically a roller shutter system for insulating glass. Background Art

[0002] Insulating glass windows with built-in roller shutters offer numerous advantages, including soundproofing and heat insulation, as well as the ability to block sunlight and sightlines as needed. The shutters themselves require no cleaning or maintenance. However, due to the small spacing between the two panes of glass in insulating glass windows, single-axis retractable roller shutter systems (such as those shown in CN214905803U and CN 213297784U) are difficult to install directly within the interlayer of an insulating glass window due to the large diameter of the retracted shutter. To overcome this problem, the current common practice is to increase the interlayer spacing of insulating glass windows. However, this approach not only compromises the energy-saving benefits of insulating glass but also lacks compatibility with commonly used door and window profiles, hindering widespread adoption. Summary of the Invention

[0003] The object of the present invention is to overcome the above-mentioned drawbacks and to provide a rolling shutter system which has a smaller diameter after rolling up, thereby reducing the requirements on the interlayer spacing of the insulating glass window.

[0004] In order to achieve the above object, the present invention is achieved as follows:

[0005] A rolling shutter system for insulating glass comprises a rolling shutter (16) and a lower beam (17) arranged at the rear end of the rolling shutter (16), a frame (21) and a transmission module (22) connected to the frame, wherein the frame (21) and the transmission module (22) are fixed on a spacer bar of the insulating glass, and the frame (21) comprises two parallel and spaced upper rollers (1), a lower roller (2), and a synchronous belt (5) arranged at both ends of the upper roller (1) and the lower roller (2). The head end of the rolling curtain (16) is fixed on the synchronous belt (5) and the rolling curtain (16) is wrapped around the synchronous belt (5), and any one of the upper reel (1) and the lower reel (2) is connected to the transmission module (22). In this way, when the external power drives the transmission module (22) to operate, the upper reel (1) and the lower reel (2) and the synchronous belt (5) are synchronously driven to rotate, so that the rolling curtain (16) wrapped around the synchronous belt (5) is wound or unfolded.

[0006] The above-mentioned design adopted by the present invention is to roll up the roller blind (16) by means of a synchronous belt (5) provided at both ends of an upper roller (1) and a lower roller (2) which are parallel and spaced a certain distance apart. Since the circumference of the synchronous belt is much greater than the circumference of a single roller, the number of turns required for completely rolling up the roller blind (16) is greatly reduced, and the number of stacked layers and thickness thereof are correspondingly greatly reduced. Thus, when the roller blind (16) is completely rolled up, the diameter thereof wrapped around the single roller will be reduced, thereby reducing the requirement for the interlayer spacing distance of the insulating glass window, so that the entire roller blind system proposed by the present invention can be installed in an insulating glass window of conventional thickness without increasing the interlayer spacing distance of the insulating glass window.

[0007] Furthermore, in the above-mentioned roller shutter system for insulating glass, the frame (21) further includes a connecting frame (4) located between the upper reel (1) and the lower reel (2), a fixing seat (3) inserted at one end of the connecting frame (4) and fixed on the insulating glass spacer, and four first synchronous pulleys (15) and a second synchronous pulley (14) rotatably connected to the fixing seat (3) and the transmission module (22) through bearings (20), wherein the synchronous pulley (14) is coaxially fixedly connected to one of the first synchronous pulleys (15), and the four first synchronous pulleys (15) are also respectively inserted at both ends of the upper reel (1) and the lower reel (2) and fixedly connected, and the second synchronous pulley (14) is also connected to the transmission module (22). The synchronous belt (5) is connected to the first synchronous pulleys (15) at both ends of the upper reel (1) and the lower reel (2) arranged in parallel and spaced apart, and the transmission module (22) is inserted into the other end of the connection frame (4); thus, when the external power drives the transmission module (22) to operate, the transmission module synchronously drives the second synchronous pulley (14) and the first synchronous pulley (15) coaxially fixedly connected thereto to rotate, thereby simultaneously driving the upper reel (1), the lower reel (2) and the synchronous belts (5) at both ends thereof to rotate, and under the action of the synchronous belt (5), the roller blind (16) wrapped around the synchronous belt (5) is wound or unfolded.

[0008] Furthermore, in the above-mentioned roller shutter system for insulating glass, considering that insulating glass windows are generally driven by motors, which may require maintenance or replacement, the motor is used as an external power source and is independent of the system. In addition, the external power source is connected to the transmission module of the system using a non-physical contact magnetic transmission method. In this way, the volume of the system can be reduced and the maintenance or replacement of the power source can be facilitated. In order to realize magnetic transmission, a gear set is required to realize the steering of power transmission, which is specifically as follows:

[0009] The transmission module (22) includes a housing (7) connected to the frame (4), a gear set and a power input wheel (6) arranged in the housing (7), a magnet (17) embedded on one side of the power input wheel (6), and the magnet (17) is used to realize magnetic transmission between the power input wheel (6) and the external power. The other side of the power input wheel (6) is also fixedly connected to the gear in the gear set, and the housing (7) is fixed on the insulating glass spacer. In this way, when the power input wheel (6) is driven by the external power to rotate, the gear set is driven to move, and the gear set transmits the power to the synchronous belt (5) and the upper reel (1) and the lower reel (2) through the second synchronous pulley (14) and the first synchronous pulley (15). The gear set includes a worm (11), one end of which is fixedly connected to a power input wheel (6), and a worm wheel (10) meshing with the worm (11). A transmission shaft (8) is provided on the worm wheel (10), and the other end of the transmission shaft (8) has a worm (9). A worm wheel (12) meshing with the worm (9) is provided below the worm (9), and a coaxial third synchronous pulley (13) is provided beside the worm wheel (12). A synchronous pulley (14) is provided below the third synchronous pulley (13), and the third synchronous pulley (13) is connected to the second synchronous pulley (14) via a transmission belt (18).

[0010] Furthermore, a groove is provided on one side surface of the power input wheel (6), and the magnet (17) is embedded in the groove; the other end of the worm (11) is fixed in a bearing (19), and the bearing (19) is embedded in the housing (7).

[0011] Through the above structure, the present invention provides a method for reducing the diameter of the rolled-up roller blind, thereby enabling the entire roller blind system to be easily installed in conventional insulating glass, thus making the popularization of insulating roller blinds easier. Furthermore, on this basis, the system separates the power source and the actuator, thereby facilitating future maintenance of conventional components and providing convenience for the daily use of electric insulating glass roller blinds.
