Description

Technical Field

[0001] The present invention relates to the technical field of door and window aluminum profiles, and more specifically, it relates to a multi-chamber high-wind-pressure-resistant and ultra-quiet system door and window aluminum profile. Background Art

[0002] With the acceleration of the urbanization process, the construction industry has developed vigorously. People's requirements for the performance of building doors and windows have been increasing day by day. Modern buildings not only pursue beautiful appearance, but also pay more attention to the performance of doors and windows in aspects such as sound insulation, heat insulation, and wind pressure resistance to provide a comfortable and safe indoor environment. The multi-chamber high-wind-pressure-resistant and ultra-quiet system doors and windows are exactly developed to meet these needs, and the aluminum alloy profiles of doors and windows are important components of the quiet system.

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

[0004] The present invention provides a multi-chamber high-wind-pressure-resistant and ultra-quiet system door and window aluminum profile to solve the technical problem of vibration in the right-angle area of the multi-chamber high-wind-pressure-resistant and ultra-quiet system door and window aluminum profile and the increase in noise in the related technology.

[0005] The present invention provides a multi-chamber high-wind-pressure-resistant and ultra-quiet system door and window aluminum profile, including an aluminum profile main body, and the aluminum profile main body has a first chamber, a second chamber, a third chamber, and a fourth chamber;

[0006] The first chamber is communicated with the outside of the aluminum profile main body, and at the same time is communicated with the fourth chamber through the second chamber, and the third chamber is communicated with the second chamber;

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

[0008] The self-adaptive conduction mechanism has a first position state and a second position state. When in the first position state, the air entering the first chamber from the outside cannot cause the self-adaptive conduction mechanism to conduct, and the air is discharged from the first chamber. When in the second position state, the air entering the first chamber will act on the self-adaptive conduction mechanism to make the first chamber and the second chamber conduct, so that the air enters the third chamber and is 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 used for diverting and storing, so that in hot weather, it is used to stabilize the temperature of the aluminum profile body. In winter, when the rainwater freezes, it enhances the firmness of the aluminum profile body. When the rainwater contacts the moisture absorption and expansion mechanism, an elongation action is carried out, so that the position of the aluminum profile body is stable.

[0010] As a further optimized solution of the present invention, the weakening mechanism includes a rotating rod and two corrugated plates. The two corrugated plates are arranged crosswise, and the middle of the corrugated plate is rotationally connected to the aluminum profile body through the rotating rod.

[0011] As a further optimized solution of the present invention, a plurality of grooves are formed in the corrugated plate.

[0012] As a further optimized solution of the present invention, the self-adaptive conduction mechanism includes a moving plate, a plug shaft, and an elastic member. The moving plate is located inside the second chamber and is fixedly connected to one end of the plug shaft. The other end of the plug shaft slides into the inside of the first chamber. When the air pressure in the first chamber is high, it acts on the plug shaft extending into the second chamber to conduct, and the moving plate is connected to the inner wall of the second chamber through the elastic member.

[0013] As a further optimized solution of the present invention, the moving plate is fixedly connected with a guide rod, and one end of the guide rod slides into the inside of the third chamber.

[0014] As a further optimized solution of the present invention, the moisture absorption and expansion mechanism includes a sleeve, a sleeve tube, and an expansion water stop strip. The sleeve is installed inside the third chamber. One end of the sleeve tube slides into the inside of the sleeve and is connected to the inner bottom wall of the sleeve through the expansion water stop strip. An exhaust hole is formed on one side of the sleeve, and an air inlet hole is formed on one side of the sleeve tube. A communication port is provided between the third chamber and the second chamber, and a cover shell is communicated at the communication port. The cover shell is fixedly sleeved with the sleeve tube and is communicated with the air inlet hole.

[0015] As a further optimized solution of the present invention, the expansion water stop strip is spirally arranged, so as to form a spiral channel inside the sleeve.

[0016] As a further optimized solution of the present invention, a sliding plate is slidably sleeved inside the moving plate. The sliding plate is connected to the top wall of the inner wall of the moving plate through a spring, and a through hole is formed on one side of the moving plate.

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

[0018] As a further optimized solution of the present invention, the third chamber is communicated with the outside through an exhaust channel; a triangular strip is installed on the outer top of the aluminum profile body.

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

[0020] The multi-chamber structure is combined with a weakening mechanism to effectively disperse the wind pressure, change the air flow direction, and reduce the direct impact of the wind force on the aluminum profile body. The self-adaptive conduction mechanism automatically adjusts the chamber connection according to the wind pressure to balance the internal and external pressures, enhancing the overall wind pressure resistance of the doors and windows and reducing the risk of damage to the doors and windows caused by strong winds.

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

[0022] In winter, the freezing of rainwater enhances the firmness of the aluminum profile body; the moisture absorption and expansion mechanism elongates under the action of rainwater, increasing the friction between the aluminum profile body and the installation position, improving the stability of the doors and windows after installation, and making them more firm and reliable during use.

[0023] Utilize rainwater to absorb heat in hot weather, stabilize the temperature of the aluminum profile body, contribute to reducing the indoor temperature, reducing the energy consumption of refrigeration equipment such as air conditioners, achieving a certain energy-saving effect, and at the same time improving the indoor comfort.

[0037] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. The functions and arrangements of the elements discussed can be changed without departing from the scope of protection of the content of this specification. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described in some examples can be combined in other examples.

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

[0039] The first chamber 101 is in communication with the outside of the aluminum profile body 1, and is simultaneously in communication with the fourth chamber 104 through the second chamber 102, and 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 - adapting conduction mechanism 3 is provided at the second chamber 102, and a moisture - absorbing and expanding mechanism 4 is provided inside the third chamber 103;

[0041] The self - adapting conduction mechanism 3 has a first position state and a second position state. When in the first position state, the air entering the first chamber 101 from the outside cannot cause the self - adapting conduction mechanism 3 to conduct, and the air is discharged from the first chamber 101. When in the second position state, the air entering the first chamber 101 acts on the self - adapting conduction mechanism 3 to make the first chamber 101 communicate with the second chamber 102, and then the air enters the third chamber 103 and is discharged.

[0042] Liquid flow holes 105 are provided between the second chamber 102 and the first chamber 101, the third chamber 103, and the fourth chamber 104 respectively. When rainwater enters the first chamber 101, the second chamber 102, the third chamber 103, and the fourth chamber 104 divert and hold the rainwater, so that in hot weather, it is used to stabilize the temperature of the aluminum profile body 1, and in winter, when the rainwater freezes, it enhances the firmness of the aluminum profile body 1. When the rainwater contacts the moisture - absorbing expansion mechanism 4, it performs an elongation action, causing the position of the aluminum profile body 1 to be stable.

[0043] The aluminum profile body 1 is provided with four chambers, constructing a complex spatial structure. The first chamber 101 serves as the starting end connected to the outside, and air enters from here. 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 flow of air and rainwater. The self - adapting conduction mechanism 3 controls the communication state between the first chamber 101 and the second chamber 102. In the first position state, the air entering the first chamber 101 from the outside cannot enter the second chamber 102 due to the obstruction of the self - adapting conduction mechanism 3 and can only be discharged from the first chamber 101. When in the second position state, the air pressure entering the first chamber 101 pushes the self - adapting conduction mechanism 3 to make it conduct, and the air can then enter the second chamber 102 and the third chamber 103 in sequence and finally be discharged. The liquid flow holes 105 between the second chamber 102 and the other three chambers play a role in rainwater management. After the rainwater enters the first chamber 101, it is diverted to other chambers through the liquid flow holes 105. In hot weather, using the characteristic of the large specific heat capacity of water, the rainwater in the chamber absorbs heat to stabilize the temperature of the aluminum profile body 1. In winter, the frozen and expanded rainwater fills the chamber to enhance the firmness of the aluminum profile body 1. When the rainwater contacts the moisture - absorbing expansion mechanism 4, this mechanism absorbs moisture and expands and elongates.

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

[0045] As a further optimized solution of the present invention, the weakening mechanism 2 includes a rotating rod 21 and two corrugated plates 22. The two corrugated plates 22 are cross - arranged, and the middle of the corrugated plate 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, thereby weakening the direct force of the air on the self-adaptive conduction mechanism 3, thereby realizing the barrier function in the first position state; when the air pressure change increases, the air acts on the self-adaptive conduction 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 impacts 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 acting 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 insertion 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 insertion shaft 32. The other end of the insertion shaft 32 slides into the first chamber 101, so that when the air pressure in the first chamber 101 is high, it acts on the insertion 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 connected. The elastic member 33 connects the movable plate 31 and the inner wall of the second chamber 102. When the air pressure decreases, the movable plate 31 is provided with a reverse elastic force to reset it and close the conduction channel, thereby automatically controlling the conduction of the chamber 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 optimized solution of the present invention, the moving plate 31 is fixedly connected with 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 moving plate 31 extends into the third chamber 103. When the moving 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 moving 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 the normal ventilation function of the doors and windows when the wind pressure changes, and reduces ventilation problems caused by mechanism failures.

[0056] As a further optimized solution of the present invention, the moisture absorption and 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. 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 hole 421 is provided on one side of the sleeve 42. A communication port 106 is provided between the third chamber 103 and the second chamber 102. A cover 44 is connected to the communication port 106, and the cover 44 is fixedly sleeved with the sleeve 42 and is communicated with the air inlet hole 421.

[0057] In the moisture absorption and expansion mechanism 4, the sleeve 41 is installed in the third chamber 103, 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 flow hole 105, it enters the sleeve 42 through the air inlet hole 421. The expansion water stop strip 43 absorbs moisture 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 inside the sleeve 41, realizing elongation.

[0058] Effect: The moisture absorption and expansion mechanism 4 elongates when encountering rainwater, increasing the friction force between the aluminum profile body 1 and the installation position.

[0059] As a further optimized solution of the present invention, the expansion water stop strip 43 is spirally arranged so as to form a spiral channel inside the sleeve 41.

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

[0061] As a further optimized solution of the present invention, a sliding plate 35 is slidably sleeved inside the moving plate 31. The sliding plate 35 is connected to the top wall of the inner wall of the moving plate 31 through a spring 36. A through hole 311 is provided on one side of the moving plate 31.

[0062] The sliding plate 35 slidably sleeved inside the moving plate 31 is connected to the top wall of the inner 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, and the sliding plate 35 slides inside the moving plate 31 under the action of the spring 36 to assist in sucking and discharging air, playing a role in flow around.

[0063] As a further optimized solution of the present invention, the first chamber 101 is respectively communicated with the outside through an inlet hole 107 and an outlet hole 108.

[0064] The inlet hole 107 of the first chamber 101 is the entrance for external air to enter. 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 optimized solution of the present invention, the third chamber 103 is communicated with the outside through an exhaust passage 109; a triangular strip 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 discharge end of the exhaust passage 109.

[0067] The exhaust passage 109 of the third chamber 103 is communicated with the outside. The air entering the third chamber 103 is discharged through the exhaust passage 109 to ensure the circular circulation of air in the entire aluminum profile chamber system. The triangular strip 5 on the top of the outer side of the aluminum profile body 1 changes the flow direction of the external air flow. When the wind blows towards the aluminum profile, the triangular strip 5 guides the air flow to flow in a specific direction towards the inlet hole 107, reducing the accumulation and turbulence of the air flow on the surface of the aluminum profile and reducing the impact force of the wind pressure on the aluminum profile.

[0068] The embodiments of the present invention have been described above. However, these embodiments are not limited to the above specific implementation manners. The above specific implementation manners are only illustrative and not restrictive. Under the inspiration of these embodiments, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of these embodiments.
