[0051] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0052] Reference below Figure 1-Figure 5 The low noise control device 100 according to the first embodiment of the present invention is described.

[0053] like Figure 1-Figure 5 As shown, the low-noise control device 100 according to the first embodiment of the present invention includes: a box body 1, a first sound insulation component, a first air inlet pipe 14 and a first air outlet pipe 15.

[0054] Specifically, the low noise control device 100 is used for a vehicle blower. A housing 1 is formed with a housing 104. A sound insulation board 101 is provided on the inner peripheral wall of the housing 104. The housing 1 is formed with an air inlet 102 and an air outlet 103. The air inlet 102 and the air outlet 103 are both connected to the housing 104. One end of the first air inlet pipe 14 passes through the air inlet 102 and is located in the housing 104. One end of the first air outlet pipe 15 passes through the air outlet 103 and is located in the housing 1 04, the first sound insulation assembly includes: a first airbag 2, a second airbag 3, a first branch pipe 4, and a second branch pipe 5. The first airbag 2 is mounted on the first air inlet pipe 14 and located at the air inlet 102. The second airbag 3 is mounted on the first air outlet pipe 15 and located at the air outlet 103. The first branch pipe 4 is located outside the housing 1. The first air inlet pipe 14 communicates with the first airbag 2 via the first branch pipe 4, and the first air outlet pipe 15 communicates with the second airbag 3 via the second branch pipe 5. Thus, the low-noise control device 100 has a simple structure and ingenious design, effectively reducing noise and minimizing its impact.

[0055] It should be understood that, by utilizing the natural flow of wind, the airflow enters the first airbag 2 from the first branch pipe 4 and enters the second airbag 3 from the second branch pipe 5, thereby filling both the first airbag 2 and the second airbag 3 with gas. The first airbag 2 fills the gap between the first air inlet pipe 14 and the surrounding wall of the air inlet 102, and the second airbag 3 fills the gap between the first air outlet pipe 15 and the surrounding wall of the air outlet 103, thereby preventing noise from propagating outward.

[0056] When the blower needs to reduce noise, the existing technology often directly wraps it with a sound insulation component to achieve the corresponding noise reduction effect. However, since the blower is provided with an air inlet and outlet duct, when the air inlet and outlet duct passes through the sound insulation component, there is often a certain gap at the connection, resulting in the noise reduction shell as a whole not being completely closed. The noise generated by the blower will be transmitted to the external environment from the gap in the noise reduction shell through the water pipe, so the noise reduction effect is not good.

[0057] According to the low-noise control device 100 of an embodiment of the present invention, a sound insulation board 101 is provided on the inner wall of the box body 1, thereby wrapping the outside of the blower for sound insulation. By providing a first sound insulation component, the first airbag 2 fills the gap between the first air inlet pipe 14 and the wall of the air inlet 102, and the second airbag 3 fills the gap between the first air outlet pipe 15 and the wall of the air outlet 103, thereby playing a sealing role, preventing noise from propagating outward, and improving the noise reduction effect. In addition, no additional power source is required to inflate the first airbag 2 and the second airbag 3, thereby avoiding excessive waste of resources.

[0058] Since the porous structure of the rock wool board has excellent attraction performance, it can effectively absorb sound waves and reduce sound reflection. The sound insulation board 101 is preferably a rock wool board. In addition, the rock wool board also has good thermal insulation performance and can effectively prevent heat transfer. Therefore, the rock wool board can not only effectively improve the sound insulation effect of the low-noise control device 100, but also has thermal insulation, fire prevention and environmental protection functions, thereby improving the safety of the low-noise control device 100.

[0059] In some embodiments of the present invention, Figure 3 As shown, the low noise control device 100 also includes: a second sound insulation component and a charging module. The second sound insulation component is arranged in the accommodating cavity 104. The second sound insulation component includes an electromagnetic component 6 and a magnetic component 7. The electromagnetic component 6 is arranged on the top wall of the accommodating cavity 104 and is located on the surrounding side of the air inlet 102. The blower is provided with a magnetic component 7. The electromagnetic component 6 and the magnetic component 7 cooperate to reduce vibration. The charging module is arranged in the first air outlet pipe 15 and is electrically connected to the electromagnetic component 6. Electricity is generated by the vibration generated by the first air outlet pipe 15.

[0060] Specifically, when the blower is turned on, the first air inlet pipe 14 and the first air outlet pipe 15 vibrate along with the blower. The charging module is located in the first air outlet pipe 15. When the first air outlet pipe 15 vibrates, the charging module generates electricity through the vibration generated by the first air outlet pipe 15. That is, the vibration generated by the blower during operation is converted into electrical energy to provide power for the electromagnetic component 6, so that the electromagnetic component 6 cooperates with the magnetic component 7 to absorb or reduce the vibration of the blower (its essence is magnetorheological damping, which can effectively control vibration and noise). Therefore, the low-noise control device 100 can not only effectively reduce the noise of the blower during operation, but also achieve self-power supply through vibration energy recovery, reflecting the energy-saving and environmental protection concept in modern engineering design.

[0061] Optionally, the magnetic member 7 is a metal plate.

[0062] Further, if Figure 3 As shown, the charging module includes: a vibration frame 8, a generator 9 and a battery accumulator 10. The vibration frame 8 is arranged on the first air outlet duct 15 and is movably connected to the generator 9. The generator 9 is electrically connected to the battery accumulator 10. A wire 12 is connected between the battery accumulator 10 and the electromagnetic component 6. The wire 12 is connected in series with a resistor 11. Specifically, when the vibration frame 8 moves due to the vibration of the air outlet duct, it drives the rotor of the generator 9 to rotate. The generator 9 converts mechanical energy into electrical energy, which is stored in the battery accumulator 10. The battery accumulator 10 is connected to the electromagnetic component 6 and provides electrical energy to the electromagnetic component 6 through the wire 12, so that the electromagnetic component 6 generates a magnetic field. The resistor 11 connected in series with the wire 12 is used to control the magnitude of the current to prevent excessive current from damaging the electromagnetic component 6 or other electrical components. It is also used to adjust the magnetic field strength of the electromagnetic component 6 to achieve the best vibration suppression effect. It can also be applied to blowers of different qualities to achieve different degrees of magnetic attraction effect.

[0063] It should be understood that the blower will produce vibrations of corresponding amplitudes under different weight conditions. Therefore, by providing the above-mentioned magnetic attraction component, the blower can be reduced to a state with the minimum amplitude vibration frequency, thereby reducing the noise impact caused by excessive vibration amplitude.

[0064] In essence, the mechanical energy of the inlet and outlet air ducts is converted into electrical energy. The generator 9 is provided with a rotating rotor and a fixed stator. The rotor is equipped with a corresponding conductive coil. When the vibration frame 8 transmits its power to the rotor through the transmission member 18024, the rotor will rotate, so that the conductive coil will generate a changing magnetic field relative to the stator. This changing magnetic field will induce a movement of electric charge on the stator and generate current, which is the electrical energy converted from mechanical energy. The converted electrical energy is stored in the accumulator 10.

[0065] In short, the generator 9, the battery 10 and the electromagnetic component 6 form a closed loop, which avoids the waste of resources, improves the practicality of the low-noise control device 100, and is beneficial to environmental protection.

[0066] In addition, the electromagnetic component 6 and the magnetic attraction component 7 cooperate to achieve magnetic attraction, which reduces the weight of the blower and the vibration amplitude of the blower, thereby achieving a noise reduction effect.

[0067] Since the low-noise control device 100 is a low-frequency circuit and does not require high precision, the resistor 11 is preferably a variable resistor 11 so that the value of the resistor 11 can be adjusted to meet the circuit requirements. However, the resistor 11 can optionally be a sliding rheostat, and the value of the resistor 11 can be adjusted by sliding contacts.

[0068] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, the low-noise control device 100 further includes a buffer assembly 13, which is disposed in the accommodating cavity 104. The buffer assembly 13 includes a limiting column 1301, a column 1302, a fixing rod 1303, and a buffer member 1304. A limiting channel 13011 is formed in the limiting column 1301. One end of the limiting column 1301 is fixed to the housing 1. The column 1302 is movably sleeved in the limiting channel 13011 along the length direction of the limiting column 1301. The fixing rod 1303 is disposed in the limiting channel 13011 and one end of the fixing rod 1303 is fixed to the housing 1. The buffer member 1304 is disposed between the column 1302 and the fixing rod 1303. Thus, the buffer member 1304 is provided to achieve a vibration reduction and buffering effect on the blower vibrating during operation.

[0069] Specifically, the buffer assembly 13 reduces the impact of the blower on the entire system during operation by physically absorbing and dispersing vibrations, thereby reducing the noise generated. In addition, by limiting the range of movement of the column 1302, damage caused by excessive vibration is avoided, thereby improving the reliability and life of the low-noise control device 100.

[0070] Optionally, the buffer member 1304 is a plastic member or a rubber member.

[0071] Furthermore, one of the upright post 1302 and the limiting post 1301 is formed with a slot, and the other of the upright post 1302 and the limiting post 1301 is formed with a slider. The upright post 1302 and the limiting post 1301 move relative to each other through the slider and the slot. This ensures a stable trajectory even under vibration, avoids unnecessary lateral deviation, and helps improve the reliability and efficiency of the entire device.

[0072] Furthermore, a buffer cavity is formed in the buffer member 1304. The low noise control device 100 further includes: a second air inlet pipe 16 and a second air outlet pipe 17. Figure 5 As shown, the second air inlet duct 16 and the second air outlet duct 17 are both connected to the buffer member 1304, and the buffer chamber is connected to the blower through the second air inlet duct 16 and the second air outlet duct 17. When the airflow generated by the blower enters the buffer chamber through the second air inlet duct 16, the change in the air volume in the buffer chamber will generate a reaction force. This reaction force can offset part of the vibration of the blower and play a vibration reduction role. At the same time, the flow of air in the buffer chamber will also reduce airflow noise; when the blower stops or slows down, the air in the buffer chamber can be slowly released through the second air outlet duct 17, avoiding the noise and vibration caused by sudden airflow changes, improving the stability of the entire device, and enhancing passenger comfort.

[0073] In some embodiments of the present invention, Figure 1 and Figure 4As shown, the low noise control device 100 also includes: a joint assembly 18, the joint assembly 18 is provided at the joint section 1501 of the first air outlet pipe 15, the joint assembly 18 includes: a flange 1801, an adjustment unit 1802, a first bracket 1803, a second bracket 1804 and a swing member 1805, the flange 1801 includes at least two, at least two flanges 1801 are sleeved on the joint section 1501 of the first air outlet pipe 15, and the adjacent two flanges 1801 are spaced apart, and the adjustment unit 1802 is provided at the adjacent two flanges 1801, the first bracket 1803 is arranged on the flange 1801, and the first brackets 1803 on the flange 1801 are arranged relatively to each other, the active screw rod 18021 and the driven screw rod 18022 are both sleeved with sliding members 1806, the second bracket 1804 is fixed on the sliding member 1806, the swinging member 1805 is connected between the first bracket 1803 and the second bracket 1804, and the relative angle between the swinging member 1805 and the first bracket 1803 is adjustable, and the relative angle between the swinging member 1805 and the second bracket 1804 is adjustable.

[0074] Specifically, the adjustment unit 1802 includes: a driving screw 18021, a driven screw 18022, a rotating member 18023 and a transmission member 18024. The driving screw 18021 and the driven screw 18022 are arranged in a direction perpendicular to the central axis of the flange 1801, and the driving screw 18021 and the driven screw 18022 are respectively arranged on both sides of the radial direction of the first air outlet duct 15. The rotating member 18023 is connected to the driving screw 18021, and the transmission member 18024 connects the driving screw 18021 and the transmission screw. The driving screw 18021 and the driven screw 18022 rotate in the same direction.

[0075] It is understood that the adjustment unit 1802 is provided between the two flanges 1801 and is capable of adjusting the distance between the two flanges 1801. The rotating member 18023 drives the active screw 18021 to rotate, and the active screw 18021 drives the driven screw 18022 to rotate via the transmission member 18024. The active screw 18021 and the driven screw 18022 rotate simultaneously, causing the sliding members 1806 on the active screw 18021 and the driven screw 18022 to displace. The displacement of the sliding members 1806 drives the angular adjustment of the swinging member 1805 relative to the second bracket 1804, thereby driving the angular adjustment of the swinging member 1805 relative to the first bracket 1803. When the sliding members 1806 on the active screw 18021 move away from each other, the distance between the two flanges 1801 decreases. When the sliding members 1806 on the active screw 18021 move toward each other, the distance between the two flanges 1801 increases.

[0076] In this way, the joint assembly 18 can be adjusted to achieve assembly in different installation spaces, thereby reducing assembly difficulty, improving assembly convenience, and enhancing assembly efficiency.

[0077] In some embodiments, as Figure 1 and Figure 4 As shown, a driving wheel 18025 is provided on the active screw rod 18021, and a driven wheel 18026 is provided on the driven screw rod 18022, and the diameters of the active wheel 18025 and the driven wheel 18026 are the same, thereby ensuring that the transmission ratio between the active wheel 18025 and the driven wheel 18026 is the same, thereby ensuring that the active screw rod 18021 and the driven screw rod 18022 rotate at the same speed, thus ensuring that the translational movement of the sliding member 1806 maintains the same speed, effectively achieving the stability of the transmission and the coordinated effect of the movement of the transmission member 18024.

[0078] Preferably, the transmission member 18024 is a transmission belt, which is sleeved on the driving wheel 18025 and the driven wheel 18026.

[0079] Furthermore, the slider 1806 is threadedly connected to the active screw 18021, and the slider 1806 is threadedly connected to the driven screw 18022. In other words, when the screw rotates relative to the slider 1806, the threads convert the rotational motion into linear motion, causing the slider 1806 to move along the axis of the screw. Furthermore, the fine pitch of the threads allows for very precise displacement control, and the threads have a certain self-locking ability, thus preventing the slider 1806 from shifting.

[0080] In some embodiments of the present invention, Figure 1 and 2 As shown, both ends of the joint section 1501 of the first air outlet duct 15 are provided with vibration-damping rings 19. The vibration-damping rings 19 are located on both sides of the joint assembly 18, and the vibration-damping rings 19 are arranged on the base 20. The vibration-damping rings 19 can reduce the vibration of the first air outlet duct 15 caused by air flow impact or mechanical vibration during operation, thereby reducing noise and improving passenger comfort. It can also protect the joint assembly 18 from vibration and extend the service life of the entire low-noise control device 100.

[0081] In some embodiments of the present invention, Figure 5 As shown, the second air inlet pipe 16 and the second air outlet pipe 17 are both provided with a one-way valve 21, thereby preventing the airflow in the second air inlet pipe 16 and the second air outlet pipe 17 from flowing back, ensuring the one-way flow of the airflow, avoiding disordered fluctuations of the airflow, and helping to reduce the noise generated when the airflow flows in the opposite direction, and also helping to protect the blower and other components from damage.

[0082] The low-noise control method according to the second embodiment of the present invention is applied to the low-noise control device 100 according to the first embodiment of the present invention.

[0083] Specifically, if Figure 6 As shown, the low noise control method includes:

[0084] Step S1, adjusting the distance between two adjacent flanges 1801;

[0085] Step S2, turning on the battery 10 to supply power to the electromagnetic element 6 and adjusting the resistance value of the resistor 11;

[0086] Step S3: Open the one-way valve 21 to supply air into the buffer chamber.

[0087] According to the low-noise control method of an embodiment of the present invention, by applying the low-noise control method of the second embodiment to the low-noise control device 100 of the first embodiment, the air duct can be effectively connected to the external pipeline to prevent the situation where the reserved gap between the pipelines is too short and the connection cannot be made. Moreover, by converting mechanical vibration into electrical energy, the weight of the blower can be adaptively reduced through the electromagnetic component 6 and the magnetic attraction component 7, thereby reducing the vibration amplitude to the minimum. Moreover, the magnetic attraction component can be reused many times without using too much additional energy, which is beneficial to environmental protection. The buffer component 1304 uses the driving force of the airflow to help it to perform corresponding elastic recovery, so that it can more quickly absorb and buffer the high-frequency vibration of the blower.

[0088] Specifically, by rotating the rotating member 18023 of the joint assembly 18, the driving and driven screws 18021 and 18022 rotate synchronously and in the same direction, driven by a transmission belt. This spiral drive causes the second brackets 1804 at each end of the slider 1806 to push the flange 1801 connected to the first bracket 1803 outward or inward. The flange 1801 compresses the joint section 1501 to compensate for its length, effectively connecting the first outlet pipe 15 to the external pipe. During blower operation, the accumulator 10 supplies power to the electromagnetic element 6 and simultaneously adjusts the variable resistor 11 on the wire 12, thereby adjusting the magnetic strength of the electromagnetic element 6. This adapts to and reduces the weight of blowers of varying sizes. Opening the one-way valve 21 allows the air flowing through the blower to pass through the second air inlet pipe 16 and second air outlet pipe 17. This effectively allows the buffer element 1304 to recover its elasticity when subjected to vibration, thereby dampening the blower's next vibration.
