Description

Technical Field

[0001] This utility model relates to the field of window technology, and specifically to a magnetic control box structure for a roller blind. Background Technology

[0002] To achieve both the light-blocking effect of roller blinds and the heat insulation performance of insulated glass, built-in roller blind insulated glass units with the roller blind installed inside the insulated glass have emerged on the market. However, these built-in roller blind insulated glass units, while ensuring the airtightness of the insulated glass, employ two main control methods: one is the built-in motor type, and the other is the sliding magnetic control type. Both methods have their advantages and disadvantages. For the built-in motor type, since the motor is installed inside the insulated glass, its overall reliability is poor, and faulty electrical components cannot be repaired or replaced. The sliding magnetic control type also suffers from problems such as complex structure, excessively long stroke of the control magnetic slider, and the occupation of a certain area of ​​the roller blind. Furthermore, existing sliding magnetic control systems often require multiple intermediate magnetic control boxes for transition when using multi-layered glass to ensure the effectiveness of the sliding magnetic control. This not only demands high skill from assemblers and increases operating costs, but also makes the magnetic control prone to failure after a period of use, resulting in complex subsequent maintenance.

[0029] A driving assembly is disposed on the window 1. The driving assembly includes an inner driving component 3 and an outer driving component 5 disposed opposite to each other. The inner driving component 3 is slidably disposed on one side of the frame 11, and the outer driving component 5 is slidably disposed on the first glass 12. The inner driving component 3 and the outer driving component 5 are magnetically connected. The inner driving component 3 is drivenly connected to the roller blind assembly 2. The outer driving component 5 is used to slide on the first glass 12 so that the inner driving component 3 can unroll or reroll the roller blind assembly 2.

[0030] The thickness of the internal drive component 3 is less than or equal to the thickness of the frame 11.

[0031] The external drive component 5 of this invention slides on the first glass 12 to allow the internal drive component 3 to unroll or reroll the roller blind assembly 2, enabling the roller blind assembly 2 to block light from the first glass 12 and the second glass 13. This allows for quick and accurate unrolling or rerolling of the roller blind assembly 2. The thickness of the internal drive component 3 is less than or equal to the thickness of the frame 11, reducing the relative distance between the internal drive component 3 and the external drive component 5. The internal drive component 3 is driven by direct magnetic attraction, which allows for better control of the magnetic attraction force. This eliminates the need for intermediate magnet components for transition, reducing the complexity of the drive mechanism.

[0032] In one embodiment of the present invention, a guide rail 4 is provided on the first glass 12, a guide block 56 is slidably provided on the guide rail 4, the external driving component 5 is connected to the guide block 56, and limit blocks 41 are provided on both sides of the guide rail 4, and the external driving component 5 reciprocates along the guide rail 4.

[0033] Specifically, the guide block 56 on the drive block 51 reciprocates along the guide rail 4, driving the slider 31, which is magnetically attracted by the first strong magnet 54, to reciprocate along the sliding groove 33 in sync. This effectively ensures the accuracy of the movement direction of the inner and outer drive components 5, and ensures that the roller shutter assembly 2 is unrolled or retracted quickly and accurately.

[0034] In one embodiment of the present invention, the external driving component 5 includes a driving block 51, a cavity 52 is provided on the driving block 51, rotating wheels 53 are provided on both sides of the cavity 52, an installation groove is provided in the middle of the cavity 52, and a first strong magnet 54 is provided on the installation groove.

[0035] Specifically, the first strong magnet 54 on the drive block 51 is magnetically connected to the second strong magnet on the slider 31. The only gap between the two is the outer cover plate and the first glass 12. The slider 31 is driven by direct magnetic attraction, which can better control the magnetic attraction force.

[0036] In one embodiment of the present invention, the driving block 51 is provided with notches 55 on both sides, and the notches 55 are provided with anti-slip textures.

[0037] Specifically, the 55 notch allows for easy pressing and pushing by the user's hands at both ends, which not only enhances the aesthetics but also improves ease of use. The anti-slip texture ensures smooth pushing.

[0038] In one embodiment of the present invention, the roller blind assembly 2 includes a rotating shaft 21, which is rotatably mounted on the top of the frame 11. A curtain 22 is provided on the rotating shaft 21, and a counterweight rod 23 is provided at the free end of the curtain 22. The rotating shaft 21 is drivenly connected to the inner drive component 3.

[0039] Specifically, the rotating shaft 21 rotates to wind the curtain 22 onto the rotating shaft 21, thereby achieving the winding of the curtain 22; driven by the counterweight rod 23, the rotating shaft 21 is rotated to unwind the curtain 22, while the connecting rope 32 is wound around the rotating shaft 21, thus achieving the unwinding of the curtain 22. The structure is simple and reasonable.

[0040] In one embodiment of the present invention, the frame 11 is provided with two guide bars 24, which are arranged parallel to each other on both sides of the frame 11. The guide bars 24 are arranged opposite to the curtain 22 and the counterweight rod 23. The guide bars 24 are provided with guide slots, and the curtain 22 and the counterweight rod 23 are slidably disposed in the guide slots.

[0041] Specifically, the curtain 22 and the counterweight rod 23 are slidably installed in the guide slots on both sides, which not only blocks the light from the gaps between the curtain 22, the counterweight rod 23 and the frame 11, but also ensures the directionality of the movement of the counterweight and the curtain 22, ensuring the smoothness of their movement and avoiding blockage.

[0042] In one embodiment of this utility model, the inner drive component 3 includes a slider 31, the frame 11 is provided with a sliding groove 33, the slider 31 is slidably disposed on the sliding groove 33, the slider 31 is provided with a connecting rope 32, the free end of the connecting rope 32 is connected to the rotating shaft 21, the slider 31 is provided with a second strong magnet, the second strong magnet is magnetically connected to the outer drive component 5, the outer drive component 5 is used to drive the slider 31 with the second strong magnet to reciprocate along the sliding groove 33, thereby driving the rotating shaft 21 to rotate to realize the unwinding or winding of the curtain 22.

[0043] Specifically, when the slider 31 moves downward, the free end of the connecting rope 32 is wrapped around the rotating shaft 21. Pulling the connecting rope 32 downward straightens it within the sliding groove 33, causing the rotating shaft 21 to rotate and wind the curtain 22 onto the rotating shaft 21, thus achieving the winding of the curtain 22. When the slider 31 moves upward, one end of the connecting rope 32 is on the rotating shaft 21, while the other part is straightened within the sliding groove 33. As the slider 31 moves upward, a counterweight rod 23 is provided at the free end of the curtain 22. Driven by the counterweight rod 23, the rotating shaft 21 rotates, unwinding the curtain 22. At the same time, the connecting rope 32 is wrapped around the rotating shaft 21, thus achieving the unwinding or winding of the curtain 22.

[0044] In one embodiment of the present invention, a guide groove 34 is provided on the inner wall of the sliding groove 33, and a guide block matching the guide groove 34 is provided on the slider 31. The thickness of the slider 31 is greater than or equal to the depth of the sliding groove 33.

[0045] Specifically, the thickness of the inner drive component 3 is less than or equal to the thickness of the frame 11, that is, the size of the thickened slider 31 is increased so that it can be directly magnetically connected to the drive block 51 without the need for an intermediate magnet component for transition. The guide block on the slider 31 can move along the guide groove 34, ensuring the stability of the movement of the thickened slider 31, and at the same time avoiding direct friction between the slider 31 and the first glass 12 or the outer cover plate, ensuring smooth movement. The thickness of the slider 31 is greater than or equal to the depth of the sliding groove 33, which can ensure that the slider 31 and the drive block 51 can be directly magnetically connected.

[0046] In one embodiment of this utility model, an intermediate glass 14 is further included. The intermediate glass 14 is disposed between the frame 11 and the first glass 12, and the intermediate glass 14 is sealed to the frame 11. The frame 11 is provided with an inner cover plate for shielding the roller blind assembly 2. The projection of the first side of the intermediate glass 14 onto the edge of the sliding groove 33 on the frame 11 is provided. The first side of the intermediate glass 14 is provided with an outer cover plate for shielding the inner drive component 3, which can make the roller blind window more aesthetically pleasing and allow the second strong magnet to be magnetically connected to the outer drive component 5. The intermediate glass 14 can achieve the advantages of complete sealing and good heat insulation.

[0047] Specifically, the projection of the first side of the middle glass 14 onto the edge of the sliding groove 33 on the frame 11 makes the area of ​​the middle glass 14 smaller than the area of ​​the first glass 12. At the same time, it can also avoid the position of the thickened slider 31, ensuring that the second strong magnet is magnetically connected to the external drive component 5. This ensures the performance of the roller blind and enables the drive of the magnetic control box without the need for an intermediate magnet component, thus reducing the complexity of the drive.

[0048] In one embodiment of the present invention, cleaning blocks 57 are provided at both ends of the guide block 56, and cleaning inclined surfaces are provided on the cleaning blocks 57. The limiting block 41 is provided with limiting inclined surfaces that match the cleaning inclined surfaces.

[0049] Specifically, cleaning blocks 57 are provided at both ends of the guide block 56, which can clean the guide rail 4 to a certain extent when the drive block 51 moves up and down, effectively avoiding jamming due to impurities and ensuring the stability of the drive block 51's movement. At the same time, cleaning components such as brushes can also be provided on it to improve its cleaning ability.

[0050] In use, the first strong magnet 54 on the drive block 51 is magnetically connected to the second strong magnet on the slider 31. The only separation between them is the outer cover plate and the first glass 12. Direct magnetic attraction drives the slider 31, allowing for better control of the magnetic force. The thickness of the inner drive component 3 is less than or equal to the thickness of the frame 11, eliminating the need for an intermediate magnet component and reducing drive complexity. The guide block 56 on the drive block 51 reciprocates along the guide rail 4, driving the slider 31, which is magnetically attracted to the first strong magnet 54, to reciprocate synchronously along the sliding groove 33. When the slider 31 moves downwards... At this time, the free end of the connecting rope 32 is wrapped around the rotating shaft 21. Pulling the connecting rope 32 downward will straighten it in the sliding groove 33, causing the rotating shaft 21 to rotate and roll the curtain 22 onto the rotating shaft 21, thus achieving the winding of the curtain 22. When the slider 31 is driven to move upward, one end of the connecting rope 32 is on the rotating shaft 21, and the other part is straightened in the sliding groove 33. The slider 31 moves upward. Since the free end of the curtain 22 is equipped with a counterweight rod 23, the rotating shaft 21 is driven to rotate under the drive of the counterweight rod 23 to unwind the curtain 22, and at the same time, the connecting rope 32 is wrapped around the rotating shaft 21, thus achieving the unwinding or winding of the curtain 22.
