[0002] Related technologies indicate that some automotive models are beginning to use wheel resonators to reduce tire cavity noise.

Different tire sizes have different resonant frequencies, so the resonator needs a convenient and simple way to adjust its resonant frequency.

[0003] In existing technologies, the installation of resonators often requires modification of the wheel rim or the use of specially made rims, which greatly increases costs and limits the scope of application. Summary of the Invention

[0022] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] The following is for reference. Figures 1 to 8 A resonant structure 100 for a wheel 200 is described according to an embodiment of the first aspect of the present invention.

[0024] like Figure 2 As shown, a resonant structure 100 for a wheel 200 according to a first aspect embodiment of the present invention includes: a resonator 110 and a strap 120.

[0025] Specifically, refer to Figure 1 The resonator 110 is fixed to the strap 120, and the resonator 110 is tied to the rim 210 of the wheel 200 by the strap 120. Thus, by fixing the resonator 110 to the rim 210 of the wheel 200 by the strap 120, the resonator 110 can be fixed to the rim 210 of the wheel 200 without modifying the rim 210, which reduces costs and facilitates maintenance.

[0026] Among them, reference Figure 3 The resonator 110 can absorb some sound energy and convert it into heat energy for dissipation, thus achieving the purpose of sound absorption. The strap 120 is formed into a strip shape, and the two ends of the strap 120 are connected by the connecting structure 122, so that the strap 120 forms a ring and is fitted onto the rim 210 of the wheel 200. The connecting structure 122 of the strap 120 can be adjusted to change the tightness, thereby changing the inner diameter of the ring formed by the strap 120 to match the rim 210 of different sizes of the wheel 200.

[0027] According to the resonant structure 100 for wheel 200 of the present invention, the resonator 110 is fixed on the strap 120 and tied to the rim 210 of wheel 200 by the strap 120, thereby fixing the resonator 110 to wheel 200 without modifying the rim 210, achieving the purpose of noise reduction. At the same time, it can be adapted to different mass-produced wheels 200, and is convenient for installation and maintenance and has low cost.

[0028] In one embodiment of the present invention, reference is made to... Figure 3 The resonator 110 is provided with a mating groove and a positioning part. The strap 120 passes through the mating groove, and the positioning part is used to restrict the resonator 110 from moving relative to the strap 120 in the circumferential direction of the rim 210. Thus, by providing the mating groove and positioning part on the resonator 110, the resonator 110 is fixed to the strap 120.

[0029] For example, refer to Figure 5and Figure 6 During the assembly of the resonator 110 and the strap 120, the positioning part on the resonator 110 first restricts the movement of the resonator 110 relative to the strap 120 in the circumferential direction of the rim 210, thereby achieving the effect of pre-positioning the resonator 110. Then, the mating groove on the resonator 110 further restricts the rotation of the resonator 110, thereby achieving the fixation of the resonator 110 and the strap 120.

[0030] In one embodiment of the present invention, reference is made to... Figure 3 and Figure 4 The positioning part is formed as a protruding positioning post 111, and the strap 120 is provided with a positioning hole 121. The positioning post 111 is adapted to the shape of the positioning hole 121, and the positioning post 111 is inserted into the positioning hole 121. Thus, by the mutual cooperation of the positioning post 111 and the positioning hole 121, the movement of the resonator 110 relative to the strap 120 in the circumferential direction of the rim 210 is restricted, and the pre-positioning of the resonator 110 relative to the strap 120 is achieved.

[0031] Furthermore, the height of the positioning pin 111 can be equal to the depth of the positioning hole 121. This ensures the stability of the fit between the positioning pin 111 and the positioning hole 121, and also prevents the free end of the positioning pin 111 from colliding with the rim 210 of the wheel 200, thus avoiding damage to the rim 210.

[0032] In one embodiment of the present invention, reference is made to... Figure 3 The resonator 110 may include a main cavity 112 and a mating plate. The main cavity 112 has a resonant cavity. The mating plate is disposed on one side of the main cavity 112 in the radial direction of the rim 210. At least one end of the mating plate in the axial direction of the rim 210 is connected to the main cavity 112. The mating plate and the main cavity 112 fit together to define a mating groove extending circumferentially along the rim 210. In this way, the strap 120 is fixed in the mating groove, further restricting the movement of the resonator 110 relative to the strap 120.

[0033] When the mating piece is connected to the main cavity 112 at one end of the rim 210 in the axial direction, the strap 120 can pass through the mating groove from the other end of the mating piece in the axial direction of the rim 210. When both ends of the mating piece in the axial direction of the rim 210 are connected to the main cavity 112, the strap 120 can pass through the mating groove from one end of the rim 210 in the circumferential direction. At the same time, it cooperates with the positioning part on the resonator 110 to fix the resonator 110 and the strap 120.

[0034] Furthermore, referring to Figure 3The resonator 110 is also equipped with an air inlet pipe 115. The incident sound wave enters the main cavity 112 through the air inlet pipe 115. The incident sound wave excites the air column in the air inlet pipe 115 to reciprocate, and friction with the peripheral wall of the air inlet pipe 115 causes some of the sound energy to be converted into heat energy and lost, thus achieving the purpose of sound absorption. When the incident sound wave has the same natural frequency as the resonator 110, resonance occurs, the air column movement intensifies, the amplitude and velocity reach their maximum, the damping is also the maximum, and the sound energy consumed is the most. Moreover, at this time, after the incident sound wave is diffused through secondary radiation from the peripheral wall of the air inlet pipe 115, due to the resonance characteristics, the energy can be stored in the main cavity 112 of the resonator 110, thereby achieving the best sound absorption effect.

[0035] Furthermore, referring to Figure 3 The fixed frequency of resonator 110 can be obtained from the Helmholtz resonant frequency formula f= The calculation is performed, where f is the lowest resonant frequency of the Helmholtz resonator 110, c is the speed of sound, s is the cross-sectional area of ​​the air intake pipe 115, d is the diameter of the air intake pipe 115, l is the length of the air intake pipe 115, and v is the volume of the main cavity 112. In the specific design process of the resonator 110, the resonant frequency of the resonator 110 can be adjusted by changing the length l of the air intake pipe 115.

[0036] In one embodiment of the present invention, reference is made to... Figure 3 The main cavity 112 has a first end and a second end opposite to each other in the axial direction of the rim 210. The mating pieces include a first pressing piece 113 and a second pressing piece 114. The first pressing piece 113 and the second pressing piece 114 are spaced apart on the main cavity 112 in the circumferential direction of the rim 210. One end of the first pressing piece 113 is connected to the first end, and the other end of the first pressing piece 113 extends toward the second end. The other end of the first pressing piece 113 is spaced apart from the surface of the main cavity 112 to form a first opening. One end of the second pressing piece 114 is connected to the second end, and the other end extends toward the first end. The other end of the second pressing piece 114 is spaced apart from the surface of the main cavity 112 to form a second opening. In this way, the strap 120 is inserted into the mating groove from the other end of the first pressing piece 113 and the other end of the second pressing piece 114, further ensuring the stability of the mating between the strap 120 and the resonator 110.

[0037] It should be noted that at the first end of the main cavity 112, the second opening between the second pressure plate 114 and the main cavity 112 is inserted into the mating groove between the second pressure plate 114 and the main cavity 112. At the second end of the main cavity 112, the first opening between the first pressure plate 113 and the main cavity 112 is inserted into the mating groove between the first pressure plate 113 and the main cavity 112. In this way, by inserting the strap 120 into the mating groove in two opposite directions, the stability of the fixation between the strap 120 and the resonator 110 can be greatly increased.

[0038] In one embodiment of the present invention, reference is made to... Figure 3 and Figure 4 The positioning part is formed as a positioning post 111, which is located between the first pressure plate 113 and the second pressure plate 114. In this way, the resonator 110 can rotate relative to the strap 120 through the positioning post 111, thereby allowing the strap 120 to pass through the mating groove between the first pressure plate 113 and the main cavity 112 and the mating groove between the second pressure plate 114 and the main cavity 112 from two opposite directions.

[0039] For example, refer to Figure 5 and Figure 6 During the process of fixing the resonator 110 and the strap 120, the positioning post 111 on the resonator 110 is first inserted into the corresponding positioning hole 121 on the strap 120. The resonator 110 rotates counterclockwise around the axis of the positioning post 111, so that the strap 120 can pass through the first opening and the second opening into the mating groove.

[0040] In one embodiment of the present invention, reference is made to... Figure 5 and Figure 6 The distance between the first pressure plate 113 and the second pressure plate 114 is not less than the width of the strap 120. This prevents the strap 120 from abutting against the first pressure plate 113 and the second pressure plate 114 when the positioning post 111 is engaged with the positioning hole 121, thereby ensuring that the strap 120 can pass through the first opening and the second opening into the mating groove.

[0041] It should be noted that if the distance between the first pressure plate 113 and the second pressure plate 114 is less than the width of the strap 120, when the positioning post 111 and the positioning hole 121 on the resonator 110 are pre-positioned, the strap 120 will abut against the first pressure plate 113 and the second pressure plate 114. In this way, when the resonator 110 rotates relative to the strap 120, the strap 120 cannot be inserted into the mating groove through the first opening and the second opening, and thus cannot achieve further fixation between the strap 120 and the resonator 110.

[0042] In one embodiment of the present invention, reference is made to... Figure 2The first pressure plate 113, the second pressure plate 114, and the positioning post 111 are all located on the inner side of the main cavity 112 in the radial direction of the rim 210. This ensures that the main cavity 112 of the resonator 110 is located on the radial outer side of the strap 120, and that most of the volume of the resonator 110 is located on the radial outer side of the strap 120. This allows the resonant structure to be fixed to the rim 210 of the wheel 200, ensuring the flatness of the radial inner side of the strap 120 and providing sufficient contact area between the strap 120 and the rim 210 of the wheel 200, thereby ensuring the stability of the fixation between the resonant structure and the rim 210 of the wheel 200.

[0043] In one embodiment of the present invention, there is one resonator 110, and the resonant mechanism may further include a balancing member, which is symmetrically arranged with the resonator 110 on both radial sides of the wheel 200, or there are multiple resonators 110, which are arranged circumferentially at intervals on the wheel 200, at least one resonator 110 is an X-axis resonator 110, and at least one resonator 110 is a Z-axis resonator 110.

[0044] It should be noted that after the tire 220 touches the ground, there are "switched modes" of the acoustic cavity in the X and Z directions. Corresponding to the overall road noise performance of the vehicle, there are often two peaks, namely fx in the X direction and fz in the Z direction. Therefore, the X and Z directions should be controlled first. Among the two peaks, the peak in the Z direction is often more prominent, so the Z direction is the highest priority to control. If the cost allows, multiple resonators 110 can be installed in one wheel 200 to achieve the best sound absorption effect.

[0045] When there is only one resonator 110, a balancing component is set. The balancing component and the resonator 110 are symmetrically distributed on both radial sides of the wheel 200. It should be noted that the resonator 110 has a certain weight, and the weight of the balancing component is equal to the weight of the resonator 110. By setting the balancing component symmetrically with the resonator 110 on both radial sides of the wheel 200, the dynamic balance problem of the wheel 200 during movement can be solved.

[0046] In one embodiment of the present invention, the resonator 110 has a resonant cavity, and an air inlet communicating with the resonant cavity is formed on the resonator 110. The central axis of the air inlet is along the tangent direction of the strap 120. There are multiple resonators 110, with the air inlets of two adjacent resonators 110 arranged at 90° intervals around the circumference of the strap 120. Alternatively, there are three resonators 110, with the air inlets of the three resonators 110 arranged at 120° intervals around the circumference of the strap 120. This ensures sufficient sound absorption in both the X and Z directions.

[0047] For example, refer to Figure 7When there are two resonators 110, the air intake pipes 115 on the two resonators 110 are arranged at an angle of 90°. This ensures that the fixed frequency of one resonator 110 is fx and the corresponding air intake pipe 115 is distributed in the X direction, while the fixed frequency of the other resonator 110 is fz and the corresponding air intake pipe 115 is distributed in the Z direction, thereby achieving the best sound absorption effect.

[0048] For example, refer to Figure 8 When there are three resonators 110, the included angle between two adjacent resonators 110 is 120°. The three resonators 110 are evenly distributed around the circumference of the rim 210. The fixed frequency of the first resonator 110 is fx, which absorbs sound energy in the X direction; the natural frequency of the second resonator 110 is fz, which absorbs sound energy in the Z direction; and the natural frequency of the third resonator 110 is fz+5, because in actual testing, the peak values ​​in the X and Z directions often deviate by ±5.

[0049] Furthermore, when there are three resonators 110, a balancer can be set between two of the resonators 110. The included angle between two adjacent resonators 110 is 90°. The balancer is used to balance the wheel during the movement process. In this way, it can be ensured that there are air inlets distributed in the X direction and air inlets distributed in the Z direction at the same time, thereby ensuring the best sound absorption effect.

[0050] Furthermore, when there are four resonators 110, the included angle between two adjacent resonators 110 is 90°, and the four resonators 110 are evenly spaced in the circumferential direction of the rim 210. The natural frequency of the first resonator 110 is fx, which absorbs sound energy in the X direction; the natural frequency of the second resonator 110 is fz, which absorbs sound energy in the Z direction; the natural frequency of the third resonator 110 is fx+5; and the natural frequency of the fourth resonator 110 is fz+5.

[0051] According to a second aspect of the present invention, a vehicle includes a wheel 200 and a resonant structure 100 for the wheel 200 according to the first aspect of the present invention described above. The wheel 200 has a rim 210, and a resonator 110 of the resonant structure is attached to the rim 210 of the wheel 200 by a strap 120.

[0052] Among them, reference Figure 1 The wheel 200 may include a rim 210 and a tire 220, with the tire 220 fitted on the radial outer side of the rim 210.

[0053] According to an embodiment of the present invention, the overall performance of the vehicle is improved by providing the resonant structure 100 for the wheel 200 of the first aspect embodiment described above.

[0054] The following will refer to Figures 1-8 A resonant structure 100 for a wheel 200 is described according to a specific embodiment of the present invention.

[0055] The resonator 110 structure for a wheel 200 according to an embodiment of the present invention includes a strap 120 and a resonator 110.

[0056] The strap 120 is formed into a strip shape, and the two ends of the strap 120 are connected by a connecting structure 122, so that the strap 120 forms a ring and is fitted onto the rim 210 of the wheel 200. The strap 120 is also provided with a positioning hole 121.

[0057] There are two resonators 110. The opening angle of the air intake pipe 115 is arranged at 90°. The resonator 110 may include: air intake pipe 115, main cavity 112, positioning post 111, first pressure plate 113 and second pressure plate 114.

[0058] The air intake pipe 115 and the main cavity 112 are used to absorb sound energy; the positioning post 111 is located between the first pressure plate 113 and the second pressure plate 114. The positioning post 111 is adapted to the shape of the positioning hole 121 on the strap 120 and is used for fixing and positioning the resonator 110 and the strap 120; the first pressure plate 113 and the second pressure plate 114 are arranged at intervals on the main cavity 112 in the circumferential direction of the rim 210. One end of the first pressure plate 113 is connected to the first end, and the other end of the first pressure plate 113 extends toward the second end. The other end of the first pressure plate 113 is spaced apart from the surface of the main cavity 112 to form a first opening. One end of the second pressure plate 114 is connected to the second end and the other end extends toward the first end. The other end of the second pressure plate 114 is spaced apart from the surface of the main cavity 112 to form a second opening. A mating groove is defined between the first pressure plate 113 and the second pressure plate 114 and the main cavity 112 for further fixing the resonator 110 to the strap 120.

[0059] Specifically, such as Figure 1 As shown, the frequencies corresponding to the peak values ​​of the wheel 200 in the X and Z directions are first obtained based on the "misalignment state" of the acoustic cavity after the wheel 200 is grounded. Then, by setting the length of the intake pipe 115 on the resonator 110, the fixed frequencies of the two resonators 110 are fx and fz, respectively. Then, the positioning post 111 on the resonator 110 is matched with the positioning hole 121 on the strap 120. The resonator 110 is rotated around the axial direction of the positioning post 111, so that the strap 120 is inserted into the matching groove between the first pressure plate 113 and the second pressure plate 114 and the main cavity 112, thus completing the fixation between the resonator 110 and the strap 120. Then, the strap 120 is sleeved on the rim 210 of the wheel 200 through the connecting structure 122. During the operation of the wheel 200, it absorbs sound energy and reduces noise.

[0060] According to the resonant structure 100 for wheel 200 of the present invention, the resonator 110 is fixed on the strap 120 and tied to the rim 210 of wheel 200 by the strap 120, thereby fixing the resonator 110 to wheel 200 without modifying the rim 210, achieving the purpose of noise reduction. At the same time, it can be adapted to different mass-produced wheels 200, and is convenient for installation and maintenance and has low cost.
