Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, specifically to a roof opening window structure. Background Technology

[0002] In large public buildings (such as stadiums and airport terminals), roof curtain walls need to balance lighting, ventilation, and airtightness. Currently, existing roof curtain wall operable window structures typically employ either a sliding curtain wall structure or a single-axis rotating curtain wall structure.

[0003] In a sliding curtain wall structure, the entire curtain wall slides along a horizontal track. When opening, space must be reserved at the top for sliding, necessitating the design of concealed cavities on the building facade. Furthermore, when the horizontal track accumulates dust or deforms, gaps can easily form between the curtain wall and the frame after closing, leading to increased water seepage during rain and compromising the building's airtightness. While a rotating curtain wall structure avoids the problems associated with horizontal tracks, the corners of the curtain wall are prone to rubbing against the roof frame during rotation, resulting in wear and tear and affecting its lifespan. Additionally, the limited rotation angle hinders large-scale opening and results in poor ventilation. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a roof opening window structure that overcomes the shortcomings of the prior art. It is reasonably designed and can effectively avoid scratching and wear between the window and the side wall of the window when the window rotates. It can also effectively avoid interference between the window and the roof curtain wall to ensure the opening angle of the window.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A roof-opening window structure includes two symmetrically arranged window bodies, which are set inside the opening window of the roof curtain wall. A rack seat is fixedly installed on both the left and right side walls of the opening window of the roof curtain wall. A rack is vertically slidably connected inside the rack seat. A gear is rotatably connected to the middle of the rack seat via a bearing. The central shaft of the gear is drively connected to the output shaft of a stepper motor. The gear meshes with the rack. A first hinge seat is fixedly installed on the lower surface of the window body near one end of the rack seat. The upper end of the rack is rotatably connected to the first hinge seat via a rotating shaft.

[0007] A support frame is provided inside the window opening of the roof curtain wall. The support frame is fixedly connected to the window opening. Support seats are fixedly installed on both the left and right sides of the support frame. The end of the support seat is connected to a fixing ring through a pin. An electric push rod is fixedly installed inside the fixing ring. A fisheye bearing is fixedly installed at the end of the telescopic shaft of the electric push rod. A second hinge seat is fixedly installed at the end of the window away from the first hinge seat. The second hinge seat is rotatably connected to the fisheye bearing through a pin.

[0008] Preferably, an electronic pin socket is fixedly installed on the support frame, and an electronic pin is installed on the side of the electronic pin socket. A locking plate is fixedly installed on the lower surface of the window away from the first hinge seat. The surface of the locking plate has a pin hole that matches the electronic pin socket. The electronic pin is inserted into the electronic pin socket in sequence and is movably connected with the locking plate through the pin hole.

[0009] Preferably, two rack seats are fixedly installed on the left and right side walls of the roof curtain wall opening, and gears are rotatably connected in the two rack seats through bearings. The central shafts of the two gears are coaxial, and the ends of the central shafts of the two gears that are close to each other are connected to the output shaft of the commutator through a coupling. The output shaft of the stepper motor is connected to the input shaft of the commutator.

[0010] This utility model provides a roof-opening window structure with the following advantages: By adopting a step-by-step control method, a stepper motor first drives a rack to move upward, causing the window to initially detach from the roof curtain wall. This effectively avoids friction and interference between the window and the inner wall of the roof curtain wall during opening, thus ensuring the smoothness of the subsequent opening process. Subsequently, the window is rotated and opened / closed through precise control of an electric push rod. The entire process is simple to operate and has a high degree of automation, effectively improving the ease of operation and safety of the roof-opening window structure. Simultaneously, the combined use of the stepper motor and the electric push rod enables precise control of the window opening angle, allowing for flexible adjustment of the window opening range according to actual needs, meeting ventilation and lighting requirements in different scenarios.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0019] Example 1, as Figure 1-4 As shown, a roof opening window structure includes two symmetrically arranged window bodies 1. The window bodies 1 are set inside the opening window of the roof curtain wall 2. The left and right side walls of the opening window of the roof curtain wall 2 are fixedly installed with rack seats 3. A rack 4 is vertically slidably connected inside the rack seat 3. A gear 5 is rotatably connected to the middle of the rack seat 3 through a bearing. The central shaft of the gear 5 is connected to the output shaft of the stepper motor 6. The gear 5 meshes with the rack 4. A first hinge seat 7 is fixedly installed on the lower surface of the window body 1 near the rack seat 3. The upper end of the rack 4 is rotatably connected to the first hinge seat 7 through a rotating shaft.

[0020] A support frame 8 is provided inside the window opening of the roof curtain wall 2. The support frame 8 is fixedly connected to the window opening. Support seats 9 are fixedly installed on both the left and right sides of the support frame 8. The end of the support seat 9 is connected to the fixing ring 10 through a pin. An electric push rod 11 is fixedly installed inside the fixing ring 10. A fisheye bearing 12 is fixedly installed at the end of the telescopic shaft of the electric push rod 11. A second hinge seat 13 is fixedly installed at the end of the window 1 away from the first hinge seat 7. The second hinge seat 13 is rotatably connected to the fisheye bearing 12 through a pin.

[0021] Working principle:

[0022] When the window 1 on the roof needs to be opened, the stepper motor 6 is first started to drive the gear 5 to rotate. Then, through the meshing transmission between the gear 5 and the rack 4, the rack 4 slides upward along the rack seat 3. In this embodiment, a vertically extending slide rail is provided in the middle of the rack seat 3. The side of the rack 4 away from the gear 5 is slidably connected to the slide rail, effectively ensuring the stability and accuracy of the rack 4 during its upward and downward sliding, avoiding operational errors caused by vibration or offset. Since the upper end of the rack 4 is connected to the first hinge seat 7 via a rotating shaft, the upward sliding of the rack 4 can lift the side of the window 1 closest to the rack seat 3, allowing the side of the window 1 to detach from the opening of the roof curtain wall 2. This effectively avoids friction and collision between the window 1 and the roof curtain wall 2 during opening, ensuring smooth opening. It also effectively avoids the structural limitations of the roof curtain wall 2 on the window 1, improving subsequent opening flexibility.

[0023] Subsequently, the telescopic shaft of the electric push rod 11 is extended, thereby driving the second hinge seat 13 to rotate through the push of the fisheye bearing 12 at the end of the telescopic shaft of the electric push rod 11. This causes the window 1 to rotate around the first hinge seat 7 as the axis, with the other end of the window 1 unfolding outward to achieve full opening of the window 1. After reaching the predetermined opening angle, the window can be kept stable through the locking function of the electric push rod 11 to ensure safety.

[0024] Similarly, when it is necessary to close the window 1 on the roof, first control the telescopic shaft of the electric push rod 11 to retract, so that the other end of the window 1 retracts inward. Then control the stepper motor 6 to run in reverse, drive the gear 5 to rotate counterclockwise, and the rack 4 to slide down along the rack seat 3. The window 1 gradually returns to the closed state, ensuring that the closing process is smooth and without collision. Finally, the window 1 is fixed by the locking function of the electric push rod 11 to ensure the stability and safety of the closed state.

[0025] The entire process employs a step-by-step control method. First, the stepper motor 6 drives the rack 4 upward, causing the window 1 to initially detach from the roof curtain wall 2. This effectively avoids direct contact between the window 1 and the roof curtain wall 2, reducing the risk of friction and collision, and ensuring the smoothness of the opening process. Subsequently, the electric push rod 11 precisely controls the rotation and opening / closing of the window 1. The entire process is simple to operate and has a high degree of automation, effectively improving the ease of operation and safety of the roof operable window structure. Simultaneously, the combined use of the stepper motor and the electric push rod enables precise control of the window opening angle, allowing for flexible adjustment of the window opening range according to actual needs, meeting the ventilation and lighting requirements in different scenarios.

[0026] In Embodiment 2, as a further preferred embodiment of Embodiment 1, an electronic pin socket 18 is fixedly installed on the support frame 8, and an electronic pin 14 is installed on the side of the electronic pin socket 18. A locking pin plate 15 is fixedly installed on the lower surface of the window 1 away from the first hinge seat 7. The surface of the locking pin plate 15 has pin holes that are compatible with the electronic pin socket 18. The electronic pins 14 are inserted into the electronic pin socket 18 in sequence and are movably connected with the locking pin plate 15 through the pin holes.

[0027] Therefore, when window 1 is closed, the electronic latch 14 can be inserted into the electronic latch socket 18 and locked to the locking plate 15 through the pin hole to prevent window 1 from opening accidentally and enhance security. When it is necessary to open window 1, simply pull the electronic latch 14 out of the electronic latch socket 18, so that the locking plate 15 and the electronic latch socket 18 are unlocked. Subsequently, during the process of controlling the stepper motor 6 to drive the rack 4 to move upward, the end of window 1 near the first hinge seat 7 will move upward, thus causing window 1 to tilt as a whole. Figure 2 As shown, at this time, the locking plate 15 on the lower surface of the other end of form 1 will gradually disengage from the electronic pin socket 18. This effectively ensures that form 1 is not obstructed during opening, ensuring smooth operation.

[0028] In Example 3, as a further preferred embodiment of Example 1, two rack seats 3 are fixedly installed on the left and right side walls of the window opening of the roof curtain wall 2. Each rack seat 3 contains a gear 5 rotatably connected via bearings. The central shafts 19 of the two gears 5 are coaxially aligned, and the ends of the central shafts 19 of the two gears 5 that are close to each other are connected to the output shaft of a commutator 17 via a coupling 16. The output shaft of the stepper motor 6 is connected to the input shaft of the commutator 17. Therefore, when the stepper motor 6 drives the gears 5 to rotate, the rotation direction of the output shaft of the stepper motor 6 can first be switched via the commutator 17. After the commutator 17 switches the output shaft of the stepper motor 6, it drives the central shafts of the two gears 5 to rotate synchronously via the coupling. This drives the two gears 5 to rotate synchronously, thereby driving the two racks 4 to move synchronously. This ensures that the two racks 4 rise or fall synchronously, achieving smooth movement of the window 1 and effectively improving the stability and operational accuracy of the system.
