Description

[0002] In the design of building curtain walls and similar structures, unit panels are a crucial component, and their opening method directly impacts overall functionality and practicality. Currently, common unit panel designs in the industry employ either partially openable or fully enclosed configurations. Partially openable structures typically only allow for limited opening and closing of the panel, with the opening angle and range strictly limited by factors such as mechanical structure and sealing performance. Fully enclosed designs, on the other hand, completely eliminate opening functionality and serve solely as a fixed enclosure.

[0036] There are two unit panels 1, which are arranged in parallel. Specifically, the unit panel 1 includes a glass panel 11, a male column 12, a female column 13, an upper crossbeam 14 and a lower crossbeam 15; the upper crossbeam 14, the male column 12, the lower crossbeam 15 and the female column 13 are connected and fixed in sequence to form a rectangular keel frame, and the glass panel 11 is installed and fixed on the rectangular keel frame, wherein the glass panel 11 can be fixed on the rectangular keel frame using structural adhesives and sealants commonly used in the field to ensure structural stability and sealing.

[0037] A unit back frame 2 is fixedly installed on the indoor side of each unit panel 1. The unit back frame 2 has a rectangular frame structure. Specifically, a plurality of connecting parts 121 are provided on the male column 12 and the female column 13. The unit back frame 2 is fixed to the male column 12 and the female column 13 through the plurality of connecting parts 121 and stainless steel bolts; the upper and lower ends of the unit back frame 2 are respectively fixed with a first open connecting frame 21 and a second open connecting frame 22.

[0038] Furthermore, in order to enhance the structural strength of the first opening connecting frame 21 and the second opening connecting frame 22, a plurality of inclined rods 211 are provided on the first opening connecting frame 21 and the second opening connecting frame 22 to avoid deformation due to force during movement.

[0039] As attached Figure 3-4 As shown, there are two first left-right moving mechanisms 3, which are horizontally arranged on the upper sides of the two unit panels 1 and connected to the first open connecting frame 21 on the upper side of the unit panels 1.

The second slider 41 and the second slide rail 42 slide together to ensure that the lower side of the unit panel 1 moves stably in the left and right directions along the second slide rail 42.

[0043] By arranging a first left-right moving mechanism 3 and a second left-right moving mechanism 4 with opposite movement directions on the upper and lower sides of the unit panel 1, the two unit panels 1 can be driven to open to both sides, avoiding obstruction of the outer surface of the building, providing sufficient operating space for maintenance equipment such as window cleaning machines, reducing the difficulty and cost of maintenance operations, and solving the problem of equipment operation being blocked by panels in traditional structures.

The front-back moving mechanism 5 is used for allowing the first left-right moving mechanism 3 and the second left-right moving mechanism 4 to move along the front-back direction.

[0046] Specifically, the front-to-back moving mechanism 5 includes two third slide rails 51 arranged parallel to each other and a third slider 52 slidably arranged on the two third slide rails 51. The third slide rail 51 is used to connect the steel pipe rail 31 or the second slide rail 42, wherein the steel pipe rail 31 slides with the third slide rail 51 through the third slider 52 located on the upper side of the unit panel 1 to drive the first left and right moving mechanism 3 to move in the front-to-back direction. Similarly, the second slide rail 42 slides with the third slide rail 51 through the third slider 52 located on the lower side of the unit panel 1 to drive the second left and right moving mechanism 4 to move in the front-to-back direction.

[0047] In this embodiment, the direction from indoor to outdoor is defined as the front-to-back direction, the side closer to the outdoor is the front, and the side closer to the indoor is the back; the left-to-right direction is defined as the plane where the front-to-back direction is located and perpendicular to the front-to-back direction.

[0048] By providing a first left-right moving mechanism 3 and a second left-right moving mechanism 4 for driving the two unit panels 1 to move to both sides, and a front-back moving mechanism 5 for driving the first left-right moving mechanism 3 and the second left-right moving mechanism 4 to move forward and backward, the movement of the unit panels 1 in the front-back, left-right and right directions is achieved. When working, the unit panels 1 can be moved indoors first, and then stored and hidden in the corners of the room on both sides without affecting the use of indoor equipment, thereby achieving complete opening of the opening, increasing the available space, and providing sufficient operating space for maintenance equipment such as window cleaning machines.

[0051] Specifically, the driving mechanism 6 includes a driving motor 61, two universal joints 62, two anglers 63 and two screw rods 64; the driving motor 61 is fixed in the middle of the driving mounting part 511, and the two universal joints 62 are arranged inside the driving mounting part 511 and on both sides of the driving motor 61. The two anglers 63 are respectively arranged at the connecting corners of the driving mounting part 511 and the two third slide rails 51, and the two screw rods 64 are respectively arranged inside the two third slide rails 51; the ends of the two universal joints 62 that are close to each other are connected to the output shaft on the driving motor 61, and the ends of the two universal joints 62 that are away from each other are respectively connected to the input ends of the two anglers 63. The angler 63 is used to convert the horizontal rotational motion of the driving motor 61 into a linear drive along the direction of the third slide rail 51. The indoor ends of the two screw rods 64 are respectively connected to the output ends of the two anglers 63, and the other ends of the two screw rods 64 are respectively connected to the two third sliders 52.

[0052] During operation, the drive motor 61 is started, and drives the screw rod 64 to rotate through the universal joint 62 and the angle adjuster 63 , and the screw rod 64 drives the third slider 52 to move forward and backward along the third slide rail 51 , thereby realizing the automatic drive of the forward and backward moving mechanism 5 .

[0053] By providing a driving mechanism 6 to provide power for the first left-right moving mechanism 3 and the second left-right moving mechanism 4 to move in the front-back direction, the front-back movement of the unit panel 1 is automated, and the synchronous movement of the unit panel 1 is achieved, thereby reducing the situation where the unit panel 1 is too heavy to be moved by manpower, thereby improving the opening efficiency.
