Technical Field

[0001] The invention relates to the technical field of hollow glass curtain walls for buildings, in particular to a magnetically controlled sunshade hollow glass curtain wall structure. Background Art

[0002] Insulating glass is composed of two or more layers of flat glass and is often used in the installation of curtain walls. It is a new type of building material that has good heat insulation, sound insulation, is beautiful and practical, and can reduce the weight of a building.

[0003] Reference Figure 1 As shown, some insulating glass also has a magnetically controlled built-in shading function, in which a shading component (which can be a curtain or a blind) needs to be arranged inside the insulating glass, and the shading component is connected to a driven component, and an active component magnetically connected to the driven component is arranged on the outside of the insulating glass. The user can drive the driven component to move by pulling the active component, thereby realizing the lifting and flipping of the shading component and achieving the purpose of shading.

[0004] However, in actual use, the force with which the user pulls the active part is different each time, which can easily cause the driven part and the active part to be misaligned, resulting in insufficient magnetic force between the driven part and the active part and demagnetization, making it impossible for the sunshade component to complete the opening / shielding function normally, reducing user satisfaction. Summary of the invention

[0008] Furthermore, the brake assembly includes: a guide rail, which is vertically installed, and the active part is slidably installed on the guide rail; a plurality of racks are opened on the guide rail; a paddle is made of non-magnetic material and is hingedly installed on the active part; the first magnetic component and the active part produce relative movement, which can approach / move away from the paddle, so as to make the paddle enter / exit the rack.

[0009] Furthermore, the mounting structure also includes: a plurality of limiting protrusions, which are arranged on the guide rail to form a rack between two adjacent limiting protrusions; a limiting surface, which is horizontally arranged on the limiting protrusion and is used to abut against the paddle; and a yielding surface, which is arranged on the limiting protrusion at a fixed angle to the horizontal plane.

DETAILED DESCRIPTION

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Reference Figure 2 As shown, an embodiment of the present invention provides a magnetically controlled sunshade hollow glass curtain wall structure including: a hollow glass 3, an active component 1 arranged outside the hollow glass 3 and a driven component 2 arranged inside the hollow glass 3, and a sunshade component 4 and the driven component 2 are transmission-connected.

[0022] Among them, the installation structure also includes: a third magnetic component 53 and a fourth magnetic component 54, which are respectively fixedly arranged in the active component 1 and the driven component 2, and can provide a second force F2 of mutual attraction. The active component 1 and the driven component 2 are magnetically connected through the second force F2, and the two are adsorbed on both sides of the insulating glass 3.

[0023] In this embodiment, the follower 2 is located inside the hollow glass 3, the sunshade component 4 can be a blind (or a curtain), and the follower 2 is connected to the pull rope of the blind; the active member 1 is located outside the hollow glass 3, and is used to drive the follower 2 to move by pulling the active member 1, thereby pulling the pull rope of the blind, so as to realize the lifting and lowering of the blind.

[0024] Among them, the installation structure also includes: a first magnetic component 51 and a second magnetic component 52, which are respectively arranged in the active component 1 and the driven component 2, and provide a first force F1 of mutual attraction; and along the movement direction of the active component 1, the first magnetic component 51 is slidably arranged in the active component 1; a braking assembly is arranged on the active component 1, is on the sliding track of the first magnetic component 51, and can brake the active component 1.

[0025] It is worth mentioning that during the upward movement of the follower 2, the user can push the active member 1 to drive the overall center of gravity of the blinds downward. At this time, the load component of the follower 2 gradually decreases, and demagnetization is not easy to occur.

[0026] Specifically, taking the downward movement of the driven member 2 as an example, the user needs to pull the active member 1 downward to drive the overall center of gravity of the blinds upward. At this time, the load on the driven member 2 gradually increases, and demagnetization is prone to occur.

[0027] In actual use, the user holds the active member 1 and applies external force to the active member 1 to guide the active member 1 to move downward in the vertical direction; when the active member 1 and the driven member 2 move synchronously (that is, the third magnetic component 53 and the fourth magnetic component 54 are not misaligned), the first force F1 and the second force F2 are both perpendicular to the insulating glass 3; that is, in the synchronous movement of the active member 1 and the driven member 2, the second magnetic component 52 can pull the first magnetic component 51 to move synchronously with the active member 1, and at this time, the first magnetic component 51 and the driven member 2 are also in a synchronous movement state, and the active member 1 and the driven member 2 work normally.

[0028] When the active member 1 and the driven member 2 move asynchronously:

[0029] On the one hand, when the user pulls the active member 1 with too much force, causing the third magnetic component 53 and the fourth magnetic component 54 to be misaligned, Figure 3 and Figure 4 As shown, in the dislocation stroke, the follower 2 will stay in place, the second magnetic component 52 and the fourth magnetic component 54 will stay still, and the active component 1 will continue to move along the movement direction; wherein, the first force F1 still remains perpendicular to the insulating glass 3, and the second force F2 is inclined at a certain angle relative to the insulating glass 3; under the action of the first force F1, the second magnetic component 52 can pull the first magnetic component 51 to stay in place, so that the first magnetic component 51 and the follower 2 are in a relatively stationary state, while the active component 1 continues to move, so that relative movement can be generated between the active component 1 and the first magnetic component 51, thereby triggering the braking assembly, limiting the active component 1 from continuing to move, and preventing the third magnetic component 53 and the fourth magnetic component 54 from demagnetization and failure.

[0030] On the other hand, after the braking assembly brakes the active component 1, the third magnetic component 53 and the fourth magnetic component 54 are still in a misaligned state, and the second force F2 is inclined at a certain angle relative to the insulating glass 3; when the user releases the active component 1, the second force F2 has a tendency to recover to a movement perpendicular to the insulating glass 3; under the action of the second force F2, the active component 1 moves in the vertical direction again in the direction close to the driven component 2 until the second force F2 is perpendicular to the insulating glass 3.

[0031] In some preferred embodiments, the offset stroke distance of the third magnetic component 53 and the fourth magnetic component 54 is controlled within half of their own length; when the offset distance of the third magnetic component 53 and the fourth magnetic component 54 is within half of their own length, the braking assembly completes the limiting operation of the active component 1, ensuring that the third magnetic component 53 and the fourth magnetic component 54 are within the demagnetization critical point, and ensuring that the second force F2 can effectively drive the third magnetic component 53 and the fourth magnetic component 54 to perform the reset stroke.

[0032] Reference Figure 5 As shown, in the reset stroke, the first force F1 remains perpendicular to the insulating glass 3, the first magnetic component 51 remains stationary relative to the driven component 2, and the active component 1 performs a reset movement until the second force F2 is perpendicular to the insulating glass 3 again; in this way, relative movement can be generated between the active component 1 and the first magnetic component 51, thereby closing the brake assembly, allowing the active component 1 and the driven component 2 to continue to move synchronously.

[0033] By using the present invention, when the user pulls the active member 1, the active member 1 can be braked promptly and effectively during the asynchronous motion of the active member 1 and the driven member 2, thereby limiting the relative displacement between the active member 1 and the driven member 2, effectively preventing the active member 1 and the driven member 2 from being demagnetized, ensuring that the active member 1 and the driven member 2 are in an effective magnetic connection state, and ensuring that the user can complete the normal sunshade operation of the sunshade component 4 through the active member 1; after the user releases the active member 1, the active member 1 loses the external force, and the active member 1 can also perform a reset movement close to the driven member 2 by itself, so as to resynchronize the active member 1 and the driven member 2, without the need for manual calibration by the user, thereby effectively improving user satisfaction.

[0034] Specifically, the braking assembly includes: a guide rail 61, which is vertically installed, and the active part 1 is slidably installed on the guide rail 61; a plurality of racks 62 are opened on the guide rail 61; a paddle 63, which is made of non-magnetic material and is hingedly installed on the active part 1; the first magnetic component 51 generates relative movement with the active part 1, and can approach / move away from the paddle 63, so as to make the paddle 63 enter / exit the rack 62.

[0035] When the active member 1 and the driven member 2 move synchronously, the paddle 63 is hidden inside the active member 1 and does not contact the rack 62; when the active member 1 and the driven member 2 are in the offset stroke, the first magnetic component 51 and the active member 1 produce relative movement, and the first magnetic component 51 moves in the direction close to the paddle 63, pushing the paddle 63 to rotate around the hinge axis until the paddle 63 protrudes a certain length from the active member 1 and enters the rack 62, and the paddle 63 and the rack 62 are in contact, so that the limiting operation of the active member 1 can be completed; when the active member 1 and the driven member 2 are in the reset stroke, the first magnetic component 51 and the active member 1 produce relative movement, and the first magnetic component 51 moves in the direction away from the paddle 63, and the paddle 63 rotates around the hinge axis under the action of gravity until the paddle 63 exits the rack 62 and returns to the active member 1.

[0036] Furthermore, the mounting structure also includes: a plurality of limiting protrusions, which are arranged on the guide rail 61, and a rack 62 is formed between two adjacent limiting protrusions; a limiting surface 641, which is horizontally arranged on the limiting protrusion and is used to abut the paddle 63; a yielding surface 642, which is inclined at a fixed angle to the horizontal plane and is arranged on the limiting protrusion to yield for the paddle 63 to rotate around the hinge axis, thereby reducing the distance between two adjacent racks 62 and shortening the braking time.

[0037] The installation structure further includes: a slider 7 on which the first magnetic component 51 is installed; and a plurality of rollers 8 rotatably provided on the active member 1 , the driven member 2 and the slider 7 .

[0038] It can be understood that when the active member 1 and the driven member 2 move synchronously, the first magnetic component 51 and the paddle 63 are installed at a fixed distance L, a slide groove is provided in the active member 1, and the active member 1 is installed in the slide groove. The length of L can be controlled by the distance between the end of the slide groove and the paddle 63, and the movement time of the first magnetic component 51 can be limited, so as to control the misalignment distance between the active member 1 and the driven member 2; to ensure that the second force F2 has sufficient strength, after the user releases the active member 1, the active member 1 can automatically reset under the action of the second force F2.

[0039] Furthermore, the third magnetic component 53 includes: a plurality of first magnets 531, along the movement direction of the active component 1, the N poles and S poles of the plurality of first magnets 531 are alternately arranged; the fourth magnetic component 54 includes: a plurality of second magnets 541, along the movement direction of the active component 1, the N poles and S poles of the plurality of second magnets 541 are alternately arranged.

[0040] It can be understood that the plurality of first magnets 531 and the plurality of second magnets 541 are symmetrically arranged in the active member 1 and the driven member 2 , which can effectively improve the adsorption strength between the third magnetic component 53 and the fourth magnetic component 54 during the synchronous movement of the active member 1 and the driven member 2 .

[0041] When the active member 1 and the driven member 2 are in asynchronous motion, in the vertical direction, an adjacent second magnet 541 above the same first magnet 531 can provide an attractive force thereto, and an adjacent second magnet 541 below the same magnet can provide a repulsive force thereto, thereby hindering the asynchronous motion trend of the active member 1 and the driven member 2 and playing a role in assisting the active member 1 and the driven member 2 to reset.

[0042] It should be understood by those skilled in the art that, although preferred embodiments of the present invention have been described, additional changes and modifications may be made to these embodiments once those skilled in the art are aware of the basic inventive concepts. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and the equivalent technology, the present invention is also intended to include these modifications and variations.
