[0025] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 3 The noise reduction structure 10 according to an embodiment of the present invention is described. The noise reduction structure 10 includes a vibration sensor 11 and a vibration adjustment component 12 .

[0026] Specifically, combined Figure 1 The vibration adjustment component 12 includes a vibration member 20, and the vibration member 20 can rotate after obtaining the signal of the vibration sensor 11.

[0027] The vibration sensor 11 is provided on the vibration source to monitor the different vibration frequencies when the vibration source generates noise in real time, and transmit the signals of different vibration frequencies to the controller. After analysis and processing, the controller forms a control signal and transmits the control signal to the vibration member 20. The vibration member 20 can rotate according to the acquired control signal to adjust the area covered by the vibration member 20 in the air or change the mass of the vibration member 20 used to adjust the vibration frequency part, thereby changing the natural frequency of the vibration member 20 itself. When the natural frequency of the vibration member 20 is the same as the vibration frequency of the vibration source, the vibration member 20 resonates, and the vibration member 20 converts the mechanical energy generated during resonance into internal energy and dissipates it in the air, thereby filtering and blocking the noise generated by the vibration source. Optionally, in the present application, the noise reduction structure 10 is provided on the vehicle, and the controller is the central processing unit of the vehicle. The central processing unit obtains the vibration frequency signal transmitted by the vibration sensor 11, analyzes and processes it to form a control signal for controlling the rotation of the vibration member 20, so that the vibration member 20 rotates a certain angle to change the area expanded or covered by the vibration member 20 in the air, so that the natural frequency of the vibration member 20 is the same or similar to the vibration frequency generated by the vibration source, and the noise generated by the vibration source is reduced by the resonance of the vibration member 20 and the vibration source.

[0028] According to the noise reduction structure 10 of the embodiment of the present invention, a rotatable vibrating member 20 is provided so that the vibrating member 20 can rotate according to the vibration frequency signal emitted by the vibration source, thereby changing the rotation angle and coverage area of the vibrating member 20 in the air, thereby changing the natural frequency of the vibrating member 20, so that the vibrating member 20 resonates within the most reasonable vibration frequency range, effectively improving the noise reduction effect of the noise reduction structure 10 on vibration sources of different vibration frequencies, and improving the flexibility and reliability of the noise reduction structure 10.

[0029] According to some embodiments of the present invention, Figure 1 As shown, the vibrating member 20 includes: a first vibrating member 21 and a second vibrating member 22. The first vibrating member 21 and the second vibrating member 22 have a first rotation position and a second rotation position. In the first rotation position, the first vibrating member 21 and the second vibrating member 22 overlap. In the second rotation position, the first vibrating member 21 and the second vibrating member 22 form an angle.

[0030] Optionally, the first vibrator 21 and the second vibrator 22 can be rotatably moved between a first rotation position and a second rotation position, and the rotation angle of the first vibrator 21 and the second vibrator 22 can be adjusted, and the positions of the first vibrator 21 and the second vibrator 22 can be changed so that the natural frequencies of the first vibrator 21 and the second vibrator 22 themselves can be adjusted according to the vibration frequency of the vibration source, so that the first vibrator 21 and the second vibrator 22 have a good resonance effect and achieve vibration reduction.

[0031] Optionally, when the vibration source generates a lower frequency vibration, the first vibrating member 21 and the second vibrating member 22 are located in a first rotation position, that is, the first vibrating member 21 and the second vibrating member 22 overlap. At this time, the unfolded area of the first vibrating member 21 and the second vibrating member 22 is smaller, the natural frequency of the vibrating member 20 is lower, and the vibrating member 20 resonates to achieve noise reduction of the lower frequency vibration source by the noise reduction structure 10.

[0032] Optionally, when the vibration source generates a higher frequency vibration, the first vibrating member 21 and the second vibrating member 22 are located in the second rotation position, that is, an angle is formed between the first vibrating member 21 and the second vibrating member 22. At this time, the unfolded area of the first vibrating member 21 and the second vibrating member 22 is larger, the natural frequency of the vibrating member 20 is higher, and the vibrating member 20 resonates to achieve noise reduction of the higher frequency vibration source by the noise reduction structure 10.

[0033] Therefore, by rotating the vibration member 20 between the first rotation position and the second rotation position, the range of the vibration member 20 for adjusting its own natural frequency can be expanded, so that the noise reduction structure 10 covers a larger range of resonance frequencies, thereby improving the resonance noise reduction effect of the noise reduction structure 10 on high-frequency noise and low-frequency noise. At the same time, since the structure of the vibration member 20 is relatively simple, the stability and reliability of the noise reduction structure 10 can be improved.

[0034] According to some embodiments of the present invention, Figure 1 As shown, the vibration adjustment component 12 includes: a driving member 23, one end of the first vibrating member 21 and one end of the second vibrating member 22 are respectively connected to the driving member 23, and the driving member 23 drives the other end of the first vibrating member 21 and the other end of the second vibrating member 22 to move between the first rotation position and the second rotation position.

[0035] The driving member 23 includes a driving motor 24 and a driving shaft 25. The first vibrating member 21 and the second vibrating member 22 are both arranged perpendicular to the axial direction of the driving shaft 25, and the driving shaft 25 axially penetrates the first vibrating member 21 and the second vibrating member 22 at one end adjacent to the driving member 23. The driving motor 24 drives the vibrating member 20 via the driving shaft 25, causing the first vibrating member 21 and the second vibrating member 22 to rotate between a first rotational position and a second rotational position at the other end away from the driving shaft 25, and changing the angle between the first vibrating member 21 and the second vibrating member 22 according to different vibration frequencies of the vibration source. Optionally, the driving member 23 is electrically connected to a controller.

[0036] Therefore, by setting the driving member 23, the driving member 23 can adjust the angle between the first vibrating member 21 and the second vibrating member 22 according to the different vibration frequencies of the vibration source, thereby adjusting the position and coverage area and natural frequency of the vibrating member 20, so that the vibrating member 20 can quickly resonate, improve the flexibility of the noise reduction structure 10, and improve the working efficiency and resonance noise reduction effect of the noise reduction structure 10.

[0037] According to some embodiments of the present invention, the angle is α, and α satisfies: 0≤α≤180°.

[0038] For example, the angle α can be 30°, 45°, 90°, or 120°. Thus, by limiting the range of the angle, the noise reduction structure 10 can cover the resonance frequency to the greatest extent, and the noise reduction structure 10 can adjust the angle between the first vibrating member 21 and the second vibrating member 22 through the driving member 23 so that the natural frequency of the vibrating member 20 can be consistent with the vibration frequency of the vibration source, which is conducive to achieving a resonant noise reduction effect on high-frequency noise and low-frequency noise.

[0039] According to some embodiments of the present invention, Figure 1 As shown, at least one of the first vibrating member 21 and the second vibrating member 22 is formed with an attraction surface 26 , and the attraction surface 26 is provided on a side surface of the first vibrating member 21 and the second vibrating member 22 adjacent to each other.

[0040] In this embodiment, a suction surface 26 is formed on the side surfaces of the first vibrating member 21 and the second vibrating member 22 adjacent to each other. The suction surface 26 is suitable for attracting the side surfaces of the first vibrating member 21 and the second vibrating member 22 adjacent to each other, so that the first vibrating member 21 and the second vibrating member 22 maintain close contact.

[0041] Therefore, by forming an attraction surface 26 on at least one of the first vibrating member 21 and the second vibrating member 22, when the vibration source generates low-frequency vibration, the reliability and stability of the overlap between the first vibrating member 21 and the second vibrating member 22 can be improved, thereby avoiding the generation of an angle and a gap between the first vibrating member 21 and the second vibrating member 22 when the vibrating member 20 resonates, thereby avoiding affecting the resonance noise reduction effect of the noise reduction structure 10 on the vibration source of low-frequency vibration.

[0042] According to some embodiments of the present invention, Figure 1 As shown, the vibration adjustment assembly 12 includes a base 27 , the vibration member 20 is disposed on the base 27 , and a mounting hole 28 is formed in the base 27 .

[0043] The base 27 extends axially along the drive shaft 25, and the mounting hole 28 passes through the middle area of the base 27 along the thickness direction of the base 27. The mounting hole 28 is suitable for cooperating with a fastener to fix the base 27. The drive motor 24 is arranged in the edge area of one side surface of the base 27 along the thickness direction of the base 27, and a fixed connection is formed between the drive motor 24 and the base 27. The drive shaft 25 axially passes through the first vibrating member 21 and the second vibrating member 22 adjacent to one end of the driving member 23 and is connected to the drive motor 24 to fix the vibrating member 20 on the base 27.

[0044] Therefore, by setting the base 27, the driving member 23 and the vibrating member 20 can be integrated on the base 27, which improves the compactness of the vibration adjustment component 12, is beneficial to reducing the space occupied by the vibration adjustment component 12, and is beneficial to the miniaturized design of the vibration adjustment component 12. At the same time, by setting the mounting hole 28, the installation of the vibration adjustment component 12 can be facilitated.

[0045] According to the noise reduction device 100 of the second embodiment of the present invention, Figure 2 As shown, the noise reduction device 100 includes: a noise reduction structure 10, which is the noise reduction structure 10 of any one of the above embodiments. The vibration sensor 11 of the noise reduction structure 10 is suitable for being arranged outside the vibration source.

[0046] In the present application, by adopting a noise reduction device 100 including a noise reduction structure 10, the natural frequency of the noise reduction structure 10 is adjusted, so that the vibration member 20 in the noise reduction structure 10 can better resonate according to the vibration frequency of the vibration source, making it easier for the noise reduction device 100 to resonate and reduce the high-frequency vibration frequency and low-frequency vibration frequency emitted by the vibration source.

[0047] According to some embodiments of the present invention, Figure 2 As shown, the noise reduction device 100 also includes: a mounting bracket 30, the mounting bracket 30 includes multiple mounting surfaces 31, the vibration adjustment components 12 are spaced apart on the multiple mounting surfaces 31, and the fasteners are suitable for passing through the mounting holes 28 of the vibration adjustment components 12 and connecting with the mounting bracket 30.

[0048] The multiple mounting surfaces 31 of the mounting bracket 30 are respectively arranged in different directions, and the multiple vibration adjustment components 12 are respectively arranged in an array on the multiple mounting surfaces 31. The fasteners are respectively provided through the mounting holes 28 on the bases 27 of the multiple vibration adjustment components 12, and respectively connect the vibration adjustment components 12 and the mounting bracket 30 in a direction perpendicular to the multiple mounting surfaces 31. Among them, the fasteners can be bolts or screws. Therefore, by arranging the vibration adjustment components 12 at intervals on the multiple mounting surfaces 31, it is convenient for the noise reduction device 100 to resonate and reduce the vibration generated by the vibration source in multiple directions, thereby improving the noise reduction effect of the noise reduction device 100 and expanding the noise reduction range of the noise reduction device 100. At the same time, by connecting the vibration adjustment component 12 and the mounting bracket 30 with fasteners, the connection strength between the vibration adjustment component 12 and the mounting bracket 30 can be improved, thereby improving the stability and reliability of the noise reduction device 100.

[0049] According to some embodiments of the present invention, Figure 2 As shown, the normals of adjacent mounting surfaces 31 are perpendicular to each other.

[0050] That is, two adjacent mounting surfaces 31 are perpendicular to each other. Thus, the noise reduction device 100 can maximize the resonance noise reduction of the vibration generated by the vibration source in multiple directions, thereby improving the noise reduction effect of the noise reduction device 100.

[0051] According to some embodiments of the present invention, Figure 2 As shown, the plurality of mounting surfaces 31 include a first mounting surface 32 , a second mounting surface 33 and a third mounting surface 34 , and the first mounting surface 32 , the second mounting surface 33 and the third mounting surface 34 are vertically connected to each other.

[0052] Combine Figure 2 The first mounting surface 32 extends along a first direction A, the second mounting surface 33 extends along a second direction B, and the third mounting surface 34 is disposed between the first mounting surface 32 and the second mounting surface 33 along a third direction C. The first direction A, the second direction B, and the third direction C are perpendicular to each other. Thus, by having multiple mounting surfaces 31 connected perpendicularly to each other, the noise reduction device 100 facilitates resonance and noise reduction in multiple directions.

[0053] According to some embodiments of the present invention, the noise reduction device 100 further includes a sound insulating member, which is suitable for being arranged on the outer surface of the vibration source.

[0054] The sound insulation has a fuzzy texture and numerous tiny voids within it. Vibrations generated by the vibration source enter the insulation and, after multiple reflections, are ultimately converted into internal energy. Alternatively, by placing sound insulation of varying weights on the surfaces of the vibration source in different directions, noise reduction can be targeted at the source's varying frequencies. Thus, by placing sound insulation on the outer surface of the vibration source, noise reduction can be achieved at the source, further blocking the propagation of noise and improving the noise reduction effectiveness and reliability of the noise reduction device 100.

[0055] According to the control method of the noise reduction structure 10 in the above embodiment according to the third aspect of the present invention, the control method of the noise reduction structure 10 includes: the vibration sensor 11 obtains the vibration frequency; the controller is suitable for receiving the vibration frequency monitoring signal fed back by the vibration sensor 11; the controller is suitable for driving the vibration member 20 to rotate through the driving member 23 of the vibration adjustment component 12.

[0056] The vibration sensor 11 is arranged outside the vibration source to monitor the vibration frequency of the vibration source in real time, and feeds back the vibration frequency monitoring signal to the controller. The controller drives the vibration member 20 to rotate through the driving member 23 of the vibration adjustment component 12 to adjust the rotation angle of the vibration member 20 in real time, thereby changing the natural frequency of the vibration member 20 and maximizing the resonance of the vibration member 20.

[0057] Therefore, by adopting the control method of the noise reduction structure 10 , the noise reduction effect of the noise reduction structure 10 on vibration sources with different vibration frequencies can be improved, and the flexibility and reliability of the noise reduction structure 10 can be improved.

[0058] According to some embodiments of the present invention, the controller is adapted to drive the vibration member 20 to rotate via the driving member 23 of the vibration adjustment assembly 12 , including: the controller transmits a control signal to the driving member 23 ; and the driving member 23 drives the vibration member 20 to rotate.

[0059] After receiving and processing the vibration frequency monitoring signal fed back by the vibration sensor 11, the controller transmits the control signal to the driving member 23 in the vibration adjustment component 12. Subsequently, the driving member 23 drives the vibration member 20 to rotate, and adjusts the angle between the first vibration member 21 and the second vibration member 22 in real time, thereby changing the natural frequency of the vibration member 20 and maximizing the resonance of the vibration member 20.

[0060] Therefore, by transmitting the control signal to the driving member 23 through the controller, the angle between the first vibrating member 21 and the second vibrating member 22 can be adjusted in real time, so that the noise reduction structure 10 can resonate and reduce the noise of vibration sources with different vibration frequencies, thereby improving the noise reduction effect and noise reduction efficiency of the noise reduction structure 10.

[0061] The vehicle according to the fourth embodiment of the present invention includes the noise reduction structure 10 or the noise reduction device 100 or the control method of the noise reduction structure 10 in the above embodiments.

[0062] In this embodiment, by adopting the noise reduction structure 10 or the noise reduction device 100 or the control method of the noise reduction structure 10, the VNH performance of the vehicle can be effectively improved, the noise generated by the engine during vehicle driving can be reduced, the user experience can be improved, the risk of engine overheating can be reduced, and the safety and reliability of the vehicle can be improved.
