Description

Technical Field

[0001] The present invention relates to the technical field of aluminum profiles for doors and windows, and more particularly to a multi-cavity aluminum profile for doors and windows with a high wind pressure resistance and ultra-quiet system. Background Art

[0002] With the acceleration of urbanization and the booming construction industry, people are increasingly demanding the performance of building doors and windows. Modern architecture not only pursues aesthetics but also focuses on sound insulation, heat insulation, wind pressure resistance, and other performance, to provide a comfortable and safe indoor environment. Multi-cavity, high-wind-pressure-resistant, ultra-quiet system doors and windows have emerged to meet these demands. Aluminum alloy door and window profiles are a key component of this silent system.

[0003] Currently, there is a major drawback when using aluminum alloy profiles for doors and windows. Since there are right-angle areas between the profiles and the holes in the wall where the windows are installed, when wind acts on the windows, the airflow will converge in these right-angle areas. This convergence phenomenon not only increases the impact of wind on the profiles, but also causes strong air vibrations, greatly increasing the amount of noise generated, accelerating profile wear, and reducing the service life of windows. Summary of the Invention

[0004] The present invention provides a multi-cavity high wind pressure resistant and ultra-quiet system door and window aluminum profile, which solves the technical problem in the related art that the multi-cavity high wind pressure resistant and ultra-quiet system door and window aluminum profile vibrates in the right-angle area and increases noise.

[0005] The present invention provides a multi-cavity high wind pressure resistant ultra-quiet system door and window aluminum profile, comprising an aluminum profile body having a first cavity, a second cavity, a third cavity and a fourth cavity;

[0006] The first chamber is in communication with the outside of the aluminum profile body, and is in communication with the fourth chamber through the second chamber, and the third chamber is in communication with the second chamber;

[0007] A weakening mechanism is provided inside the first chamber, a self-adaptive conduction mechanism is provided at the second chamber, and a moisture absorption and expansion mechanism is provided inside the third chamber;

[0008] The self-adaptive conductive mechanism has a first position state and a second position state. In the first position state, air entering the first chamber from the outside cannot cause the self-adaptive conductive mechanism to conduct, and the air is discharged from the first chamber. In the second position state, air entering the first chamber acts on the self-adaptive conductive mechanism to connect the first chamber to the second chamber, thereby causing the air to enter the third chamber and be discharged.

[0009] Liquid flow holes are respectively provided between the second chamber and the first chamber, the third chamber and the fourth chamber. When rainwater enters the first chamber, the second chamber, the third chamber and the fourth chamber are diverted to store it, so that the temperature of the aluminum profile body can be stabilized in hot weather. In winter, the freezing of rainwater enhances the firmness of the aluminum profile body. When rainwater contacts the moisture absorption and expansion mechanism, it stretches, causing the position of the aluminum profile body to be stable.

[0010] As a further optimization solution of the present invention, the weakening mechanism includes a rotating rod and two wave plates. The two wave plates are cross-arranged, and the middle part of the wave plate is rotatably connected to the aluminum profile body through the rotating rod.

[0011] As a further optimization solution of the present invention, a plurality of grooves are provided on the wave plate.

[0012] As a further optimization scheme of the present invention, the self-adaptive conduction mechanism includes a movable plate, an insertion shaft and an elastic member. The movable plate is located inside the second chamber and is fixedly connected to one end of the insertion shaft. The other end of the insertion shaft slides into the interior of the first chamber, so that when the air pressure in the first chamber is high, it acts on the insertion shaft to extend into the second chamber for conduction. The movable plate is connected to the inner wall of the second chamber through the elastic member.

[0013] As a further optimization solution of the present invention, the movable plate is fixedly connected to a guide rod, and one end of the guide rod slides into the interior of the third chamber.

[0014] As a further optimization scheme of the present invention, the hygroscopic expansion mechanism includes a sleeve, a sleeve, and an expansion water stop strip. The sleeve is installed inside the third chamber, one end of the sleeve slides into the interior of the sleeve, and is connected to the inner bottom wall of the sleeve through the expansion water stop strip. An exhaust hole is provided on one side of the sleeve, and an air inlet hole is provided on one side of the sleeve. A connecting port is provided between the third chamber and the second chamber, and a cover is connected at the connecting port. The cover is fixedly mounted on the sleeve and connected to the air inlet hole.

[0015] As a further optimization solution of the present invention, the expansion water stop strip is spirally arranged so that a spiral channel is formed inside the sleeve.

[0016] As a further optimization solution of the present invention, the internal sliding sleeve of the movable plate is provided with a sliding plate, the sliding plate is connected to the inner wall and top wall of the movable plate through a spring, and a through hole is opened on one side of the movable plate.

[0017] As a further optimization solution of the present invention, the first chamber is connected to the outside through an inlet hole and an outlet hole respectively.

[0018] As a further optimization solution of the present invention, the third chamber is connected to the outside through an exhaust channel; a triangular bar is installed on the top of the outer side of the aluminum profile body.

[0019] The beneficial effects of the present invention are:

[0020] The multi-cavity structure cooperates with the weakening mechanism to effectively disperse wind pressure, change the direction of airflow, and reduce the direct impact of wind on the aluminum profile body. The self-adaptive conduction mechanism automatically adjusts the cavity connection according to the wind pressure, balances the internal and external pressures, enhances the overall wind pressure resistance of doors and windows, and reduces the risk of damage to doors and windows caused by strong winds.

[0021] The weakening mechanism weakens the impact of airflow and reduces the noise generated by air vibration. The coordinated operation of the self-adaptive conduction mechanism and the hygroscopic expansion mechanism components avoids abnormal ventilation noise caused by unstable wind pressure. The overall structure effectively reduces the external noise entering the room, creating a quiet indoor environment.

[0022] Freezing rain in winter enhances the firmness of the main body of the aluminum profile; the hygroscopic expansion mechanism stretches under the action of rain, increasing the friction between the main body of the aluminum profile and the installation position, improving the stability of the doors and windows after installation, making them more firm and reliable during use.

[0023] Using rainwater to absorb heat in hot weather and stabilize the temperature of the aluminum profile body can help lower the indoor temperature, reduce the energy consumption of air conditioners and other refrigeration equipment, achieve certain energy-saving effects, and improve indoor comfort.

[0037] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. Furthermore, features described for some examples may be combined in other examples.

[0038] like Figures 1 to 6 As shown, a multi-cavity high wind pressure resistant ultra-quiet system door and window aluminum profile according to an embodiment of the present invention includes an aluminum profile body 1, which has a first cavity 101, a second cavity 102, a third cavity 103 and a fourth cavity 104;

[0039] The first chamber 101 is in communication with the outside of the aluminum profile body 1 and is in communication with the fourth chamber 104 through the second chamber 102. The third chamber 103 is in communication with the second chamber 102.

[0040] A weakening mechanism 2 is provided inside the first chamber 101, a self-adaptive conduction mechanism 3 is provided at the second chamber 102, and a moisture absorption expansion mechanism 4 is provided inside the third chamber 103;

[0041] The self-adaptive conductive mechanism 3 has a first position and a second position. In the first position, air entering the first chamber 101 from the outside cannot cause the self-adaptive conductive mechanism 3 to conduct, and the air is discharged from the first chamber 101. In the second position, air entering the first chamber 101 acts on the self-adaptive conductive mechanism 3, so that the first chamber 101 and the second chamber 102 are connected, and the air enters the third chamber 103 and is discharged.

[0042] Liquid flow holes 105 are respectively provided between the second chamber 102 and the first chamber 101, the third chamber 103 and the fourth chamber 104. When rainwater enters the first chamber 101, the second chamber 102, the third chamber 103 and the fourth chamber 104 are diverted to store it, so that in hot weather, the temperature of the aluminum profile body 1 is stabilized. In winter, the freezing of rainwater enhances the firmness of the aluminum profile body 1. When rainwater contacts the hygroscopic expansion mechanism 4, it stretches, causing the position of the aluminum profile body 1 to be stable.

[0043] The aluminum profile body 1 is provided with four chambers, forming a complex spatial structure. The first chamber 101 is the starting end connected to the outside, and air enters from it. It is indirectly connected to the fourth chamber 104 through the second chamber 102. The third chamber 103 is also connected to the second chamber 102, providing a path for the circulation of air and rainwater. The self-adaptive conduction mechanism 3 controls the communication state of the first chamber 101 and the second chamber 102. In the first position, the air entering the first chamber 101 from the outside cannot enter the second chamber 102 due to the obstruction of the self-adaptive conduction mechanism 3 and can only be discharged from the first chamber 101; when in the second position, the air pressure entering the first chamber 101 is Push the self-adaptive conduction mechanism 3 to make it conductive, and the air can enter the second chamber 102 and the third chamber 103 in turn, and finally be discharged. The flow hole 105 between the second chamber 102 and the other three chambers plays a role in rainwater management. After the rainwater enters the first chamber 101, it is diverted to other chambers through the flow hole 105. In hot weather, the rainwater in the chamber absorbs heat due to the large specific heat capacity of water, and stabilizes the temperature of the aluminum profile body 1; in winter, the rainwater freezes and expands, filling the chamber and enhancing the firmness of the aluminum profile body 1; when the rainwater contacts the hygroscopic expansion mechanism 4, the mechanism absorbs moisture and expands and elongates.

[0044] The multi-cavity structure effectively disperses wind pressure, reduces the direct impact of wind on aluminum profiles, and reduces noise. At the same time, the utilization of rainwater improves the performance of aluminum profiles in different seasons and improves the stability and durability of doors and windows.

[0045] As a further optimization solution of the present invention, the weakening mechanism 2 includes a rotating rod 21 and two wave plates 22. The two wave plates 22 are cross-arranged, and the middle of the wave plates 22 is rotatably connected to the aluminum profile body 1 through the rotating rod 21.

[0046] The rotating rod 21 in the weakening mechanism 2 is the rotating axis of the wave plate 22, and the two cross-arranged wave plates 22 can rotate around it. When external air enters the first chamber 101, the air generates pressure and impact force on the wave plate 22. The special cross structure of the wave plate 22 causes it to rotate when subjected to force, changing the flow direction and pressure distribution of the air. For example, when the air impacts the wave plate 22, the wave plate 22 rotates to convert part of the air kinetic energy into its own rotational energy, weakening the direct force of the air on the self-adaptive conducting mechanism 3, thereby realizing the blocking function in the first position state; when the air pressure change increases, the air acts on the self-adaptive conducting mechanism 3 and enters the second position state.

[0047] As a further optimization solution of the present invention, a plurality of grooves are formed on the wave plate 22 .

[0048] The multiple grooves on the wave plate 22 increase the contact area with the air. When the air hits the wave plate 22, the grooves cause the air to generate turbulence on the contact surface. These turbulences interfere with each other, consume the kinetic energy of the air, and further weaken the pressure and impact force of the air before it acts on the self-adaptive conducting mechanism 3. At the same time, the grooves change the flow path of the air on the surface of the wave plate 22, increase the flow complexity, and better control the direction of the air.

[0049] The presence of the groove significantly enhances the weakening effect of the weakening mechanism 2 on air, further improves the wind pressure resistance of the doors and windows, and reduces the risk of damage to the doors and windows caused by strong winds.

[0050] As a further optimization scheme of the present invention, the self-adaptive conduction mechanism 3 includes a movable plate 31, an insert shaft 32 and an elastic member 33. The movable plate 31 is located inside the second chamber 102 and is fixedly connected to one end of the insert shaft 32. The other end of the insert shaft 32 slides into the interior of the first chamber 101, so that when the air pressure in the first chamber 101 is strong, it acts on the insert shaft 32 to extend into the second chamber 102 for conduction. The movable plate 31 is connected to the inner wall of the second chamber 102 through the elastic member 33.

[0051] The movable plate 31 of the self-adaptive conduction mechanism 3 is located in the second chamber 102 and is fixed to one end of the plug shaft 32. When the air pressure in the first chamber 101 is greater than that in the second chamber 102, the air pushes the plug shaft 32 to slide toward the second chamber 102, driving the movable plate 31 to move, so that the first chamber 101 and the second chamber 102 are conductive. The elastic member 33 connects the movable plate 31 and the inner wall of the second chamber 102. When the air pressure decreases, it provides a reverse elastic force for the movable plate 31 to reset it and close the conduction channel, thereby automatically controlling the chamber conduction according to the change in air pressure.

[0052] The self-adaptive conduction mechanism 3 can automatically respond to changes in air pressure, achieve ventilation, balance the pressure inside and outside the chamber, avoid ventilation abnormalities caused by unstable wind pressure, and reduce noise generation.

[0053] As a further optimization solution of the present invention, the movable plate 31 is fixedly connected to a guide rod 34 , and one end of the guide rod 34 slides into the interior of the third chamber 103 .

[0054] One end of the guide rod 34 fixedly connected to the movable plate 31 extends into the third chamber 103. When the movable plate 31 moves under the action of air pressure, the guide rod 34 slides along the inner wall of the third chamber 103. The guide rod 34 provides guidance for the movement of the movable plate 31, ensuring its stable movement, preventing deviation or jamming, and ensuring the normal operation of the self-adaptive conduction mechanism 3. At the same time, the connection stability between the self-adaptive conduction mechanism 3 and the third chamber 103 is enhanced.

[0055] The guide rod 34 improves the reliability and stability of the self-adaptive conduction mechanism 3, ensures that the ventilation function of the doors and windows is normal when the wind pressure changes, and reduces ventilation problems caused by mechanism failure.

[0056] As a further optimization scheme of the present invention, the hygroscopic expansion mechanism 4 includes a sleeve 41, a sleeve 42, and an expansion water stop strip 43. The sleeve 41 is installed inside the third chamber 103, and one end of the sleeve 42 slides into the interior of the sleeve 41 and is connected to the inner bottom wall of the sleeve 41 through the expansion water stop strip 43. An exhaust hole 411 is provided on one side of the sleeve 41, and an air inlet 421 is provided on one side of the sleeve 42. A connecting port 106 is provided between the third chamber 103 and the second chamber 102. The connecting port 106 is connected to a cover shell 44, and the cover shell 44 is fixedly mounted on the sleeve 42 and connected to the air inlet hole 421.

[0057] In the hygroscopic expansion mechanism 4, the sleeve 41 is installed in the third chamber 103, and one end of the sleeve 42 extends into the sleeve 41 and is connected to the inner bottom wall of the sleeve 41 through the expansion water stop strip 43. When rainwater enters the third chamber 103 through the continuous liquid hole 105, it enters the sleeve 42 from the air inlet 421, and the expansion water stop strip 43 absorbs water and expands. Since the expansion water stop strip 43 connects the sleeve 42 and the sleeve 41, its expansion pushes the sleeve 42 to slide in the sleeve 41 to achieve elongation.

[0058] Effect: The hygroscopic expansion mechanism 4 expands when encountering rain, thereby increasing the friction between the aluminum profile body 1 and the installation position.

[0059] As a further optimization solution of the present invention, the expansion water stop strip 43 is spirally arranged so that a spiral channel is formed inside the sleeve 41.

[0060] The air entering the housing 44 through the communication port 106 can enter the sleeve 42 and then flow through the spiral channel to weaken the airflow.

[0061] As a further optimization solution of the present invention, the internal sliding sleeve of the movable plate 31 is provided with a sliding plate 35 , which is connected to the inner wall and top wall of the movable plate 31 through a spring 36 , and a through hole 311 is opened on one side of the movable plate 31 .

[0062] The sliding plate 35 slidingly fitted inside the moving plate 31 is connected to the inner wall and top wall of the moving plate 31 through a spring 36. A through hole 311 is provided on one side of the moving plate 31. When the air pressure in the first chamber 101 suddenly changes or fluctuates greatly, the moving plate 31 moves in the horizontal direction. The sliding plate 35 slides inside the moving plate 31 under the action of the spring 36 to assist in the absorption and release of air, thereby playing a role of bypass flow.

[0063] As a further optimization solution of the present invention, the first chamber 101 is connected to the outside through the inlet hole 107 and the outlet hole 108 respectively.

[0064] The inlet hole 107 of the first chamber 101 is the entrance for external air to enter, and the outlet hole 108 is used to discharge the air and liquid in the first chamber 101. The inlet hole 107 and the outlet hole 108 ensure the air circulation between the first chamber 101 and the outside. The outlet hole 108 is also used to discharge excessive rainwater in the four chambers.

[0065] As a further optimization solution of the present invention, the third chamber 103 is connected to the outside through the exhaust channel 109; a triangular bar 5 is installed on the top of the outer side of the aluminum profile body 1.

[0066] A one-way exhaust valve 6 is provided at the exhaust end of the exhaust channel 109 .

[0067] The exhaust channel 109 of the third chamber 103 is connected to the outside, and the air entering the third chamber 103 is discharged through the exhaust channel 109, ensuring the circulation of air in the entire aluminum profile chamber system. The triangular bar 5 on the top outside of the aluminum profile body 1 changes the direction of the external airflow. When the wind blows towards the aluminum profile, the triangular bar 5 guides the airflow in a specific direction and flows toward the inlet hole 107, reducing the airflow gathering and turbulence on the surface of the aluminum profile, and reducing the impact of wind pressure on the aluminum profile.

[0068] The above describes an embodiment of the present invention, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
