Description

Technical Field

[0001] The present invention relates to a vehicle wheel equipped with a resonator module for improving fastening force. More specifically, the present invention relates to a vehicle wheel equipped with a resonator module for improving fastening force, comprising a first receiving groove and a second receiving groove. The first receiving groove is spaced a predetermined distance inward from both side surfaces of the resonator module and is adapted to receive a fastening band therein to improve the fastening force between the rim and the resonator module. The second receiving groove is formed by engraving from the lower surface of the first receiving groove in such a manner as to receive a stopper for the fastening band. Background Art

[0002] The contents described herein merely provide background information related to the present invention and do not constitute prior art.

[0003] Generally, in vehicles, noise is generated by various factors and flows into the vehicle interior. Among them, the most important factor is road noise generated by the road surface, which can be divided into road noise, roaring noise, rumbling noise, etc.

[0004] Moreover, the above-mentioned road noise is often generated by the ground, tires, wheels, suspension, etc. Moreover, this road noise can cause serious discomfort to the driver, so methods for reducing this noise are constantly being studied.

[0005] As a method for reducing noise, a resonance-type noise reduction module is generally used for vehicle wheels. The noise reduction module measures a specific wavelength range of noise and cancels the noise by canceling the wavelength range of the noise in the corresponding wavelength range.

[0006] On the other hand, a vehicle wheel requires a method for coupling and fixing such a resonator module to the vehicle wheel.

[0007] In a conventional vehicle wheel (Japanese Patent No. 6227705), the resonator module and the rim are fastened together by coupling a fixing portion disposed on one side of the resonator module with a fixing groove disposed on one side of the rim.

[0008] However, the existing method of fastening the resonator module to the wheel rim has the following problem: after the injection molding or manufacturing process of the components, further processing of the fixing portion and the fixing groove is required, thereby increasing production costs.

[0009] Furthermore, it is necessary to add a production process of adjusting the positions of the fixing portion and the fixing groove and fastening the fixing portion and the fixing groove to each other, which inevitably leads to further deformation of the existing vehicle wheel production line.

[0010] Furthermore, when the bottom surface of the resonance space is directly exposed to the surface of the rim by being opened, the following problem may occur only by combining the fixing portion and the fixing groove: the resonator module may be lifted from the rim due to the wind pressure generated by the rotation of the vehicle wheel, thereby reducing the resonance sound cancellation effect.

[0011] Therefore, there is a growing need for a vehicle wheel including a self-fastening unit that fastens the resonator module itself to the rim.

[0012] In order to solve the above-mentioned problems of existing vehicle wheels, some domestic and overseas related companies have conducted research on wheels with fastening units. However, for actual productization, the cost of configuring the rim structure to form additional fastening units is too high, or even if not, the effect of increasing the fastening force is not significant compared to the preparation cost of the corresponding device. Therefore, the market competitiveness has declined compared with existing vehicle wheels, and no formal commercialization examples have been found.

[0013] Therefore, as described above, there is a need to develop a device that can solve the problems of the prior art. Summary of the Invention

[0014] The object of the present invention is to remedy the above-mentioned shortcomings of the prior art, and the objects of the present invention are as follows.

[0015] First, in addition to the resonator module's own fastening means, a vehicle wheel is provided that improves the fastening force between the rim and the resonator module for the first time by including first and second receiving grooves capable of receiving additional fastening means such as a fastening band.

[0016] Secondly, the height of the first receiving groove gradually increases from the inside toward the outside, and the fastening band received therein is pressed downward along the outside of the resonator module, thereby providing a second enhancement of the fastening force between the rim and the resonator module for the vehicle wheel.

[0017] The purpose of the present invention is not limited to the above-mentioned purpose, and those skilled in the art can clearly understand other purposes not mentioned through the following description.

[0018] According to the present invention, a vehicle wheel is provided with a resonator module for improving fastening force, comprising: a spoke; a rim connected to a peripheral portion of the spoke; and a resonator module including a rim contact portion and a resonating portion, wherein the rim contact portion surrounds the periphery of the outer peripheral surface of the rim, and the resonating portion is formed so as to surround at least a portion of the length of the rim contact portion and to form a resonating space between the rim contact portion and the resonating portion.

[0019] In this case, the resonator module may include a first receiving groove spaced a predetermined distance from both side surfaces of the resonator module along the inner side direction, and the first receiving groove may receive a fastening band therein to improve the fastening force between the rim and the resonator module.

[0020] Furthermore, the resonator module may include an anti-separation guide disposed between two side surfaces of the resonator module and the first receiving groove and protruding from an upper surface of the resonator module to prevent the fastening band from being separated from the resonator module.

[0021] Furthermore, at least one of the anti-separation guides disposed on both sides of the resonator module may include a spacer, and the spacer provides a space for withdrawing and replacing the fastening belt inserted into the first receiving groove by ensuring a remaining space.

[0022] On the other hand, the resonator module may include a second receiving groove, wherein the second receiving groove is engraved from the lower surface of the first receiving groove in a manner capable of receiving the stopper of the fastening belt.

[0023] According to another feature of the present invention, in the first receiving groove, the tightening belt is pressed downward along the outer side of the resonator module, so that its height gradually increases from the inner side to the outer side, thereby improving the tightening force between the resonator module and the rim.

[0024] In this case, the present invention is characterized in that the spacer and the second receiving groove are continuously arranged on the same line on the widthwise axis of the resonator module.

[0025] Furthermore, the present invention may include a lightweight portion that is perforated on one side of the resonator module in order to reduce the weight of the resonator module.

[0026] Furthermore, the present invention may include a coupling portion disposed at an end portion of the resonator module, so that a plurality of resonator modules can be coupled and fixed.

[0027] Further technical solutions of the present invention will be partially described in the following description and can be easily confirmed in part from the description or can be known through practice of the present invention.

[0028] The foregoing general description and the following detailed description are merely exemplary and illustrative, and are not intended to limit the present invention as described in the claims.

[0029] Hereinafter, the effects of the present invention configured as described above will be described.

[0030] First, in addition to the resonator module's own fastening unit, the fastening force between the rim and the resonator module can be improved for the first time by including the first receiving groove and the second receiving groove capable of receiving an additional fastening unit such as a fastening tape.

[0031] Secondly, the height of the first receiving groove gradually increases from the inside toward the outside, and the fastening band received therein is pressed downward along the outside of the resonator module, thereby providing a second vehicle wheel that improves the fastening force between the rim and the resonator module.

[0032] The effects of the present invention are not limited to the effects mentioned above, and a person skilled in the art can clearly understand other effects not mentioned through the description in the scope of protection claimed in the invention. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the numbers used in the description process of this specification are only used to distinguish one structural element from another structural element.

[0041] Furthermore, the suffixes “part” of the structural elements used in the following description are used or mixed for ease of writing the description, and do not have any distinguishing meanings or functions.

[0042] Figure 1 This is a perspective view of a vehicle wheel according to an embodiment of the present invention.

[0043] Figure 2 FIG. 1 is a detailed diagram of a resonator module 100 according to an embodiment of the present invention.

[0044] A vehicle wheel according to an embodiment of the present invention may include a spoke 10 , a rim 20 , and a resonator module 100 .

[0045] The spoke 10 may be composed of a peripheral portion and a plurality of support portions extending radially from a central portion toward the peripheral portion.

[0046] In this embodiment, multiple support portions are adjacently arranged at predetermined intervals, and the number of support portions and the intervals between the support portions are not limited. In other words, the support portions can be formed to a predetermined thickness, and an appropriate number of support portions can be arranged considering the entire circumference of the vehicle wheel.

[0047] The rim 20 is cylindrical in shape as a whole and is formed to be connected to the peripheral portion of the spoke 10 so that the tire can be coupled. It is a matter of course that the shape of the rim 20 can be formed into various shapes without limitation.

[0048] Since general matters of the spoke 10 and the rim 20 are obvious to those skilled in the art, detailed description thereof will be omitted.

[0049] The resonator module 100 entirely surrounds the outer peripheral surface of the rim 20 and performs a function of absorbing resonance sound generated when the vehicle is running.

[0050] Specifically, in this embodiment, the resonator module 100 may include a rim contact portion and a resonance portion 120. The rim contact portion surrounds the outer peripheral surface of the rim 20, and the resonance portion 120 is formed in a manner of surrounding at least a portion of the length of the rim contact portion and forming a resonance space between the rim contact portion and the resonance portion.

[0051] That is, the rim contact portion is formed to be long in the longitudinal direction, thereby forming the bottom surface of the resonator module 100 , and the resonance portions 120 are connected along the longitudinal direction of the rim contact portion to form a resonance space.

[0052] In particular, in this embodiment, the entire length of the rim contact portion corresponds to the circumferential length of the rim 20, and a plurality of resonating portions 120 are disposed along the length of the rim contact portion. In this embodiment, a total of four resonating portions 120 are disposed, but this is not limiting and a fewer or greater number of resonating portions 120 may be disposed.

[0053] Furthermore, the resonance space is formed in a generally closed configuration, but a partially protruding resonance neck can be formed at a predetermined position within the resonance portion 120 to connect the resonance space to the outside. Thus, the resonator module 100 of the present invention, comprising the resonance space and the resonance neck extending from the end of the resonance space, forms a Helmholtz resonator structure, absorbing resonant sound within a predetermined frequency band generated between the road surface and the rim.

[0054] In this case, the height of the resonant neck is preferably the same as the height of the resonant portion 120, and the width of the resonant neck is preferably narrower than the width of the resonant portion 120. Furthermore, the resonant neck is preferably formed by extending at least one of the ends of the resonant portion 120 to the center between adjacent resonant portions 120. However, this is not limiting, and various configurations are possible.

[0055] The principle of the Helmholtz resonator is obvious to those skilled in the art, and the related detailed description will be omitted.

[0056] The resonator module 100 may be made of various fiber materials such as synthetic fiber, natural fiber, or carbon fiber. Specifically, in this embodiment, the resonator module 100 is made of polypropylene (PP).

[0057] The resonator module 100 may include a lightweight portion 190 that is perforated on one side of the resonator module 100 in order to reduce the weight of the resonator module 100 .

[0058] Polypropylene, a polymer of propylene, is one of the lightest and thinnest plastics, with a specific gravity of 0.82 to 0.92. Its overall physical properties are similar to those of polyethylene, but it surpasses polyethylene in terms of stress-crushing resistance, transparency, and tensile strength. It is lighter and thinner than polyethylene, has better heat resistance, and exhibits excellent hinge properties, resisting damage even after repeated folding or unfolding. It also exhibits excellent electrical properties and is resistant to acids, alkalis, salt water, alcohol, gasoline, and oils. Its stress-crack resistance is superior to that of polyethylene. Therefore, the lightweight and highly productive nature of the resonator module 100 can reduce costs, thereby minimizing production costs.

[0059] Furthermore, a coupling portion 180 may be included and disposed at an end of the resonator module 100 to couple and fix a plurality of resonator modules 100 .

[0060] like Figure 2As shown, the connecting portion 180 can be used to connect one side of one resonator module 100 to the other side of another resonator module 100 using a hook-like door hook. Furthermore, to further enhance the fastening force, one of ultrasonic welding, heat welding, or vibration welding can be selectively applied to the surface of the connecting portion 180, and an adhesive / bonding agent can be applied. These methods can be performed independently or in parallel, and the connecting portion 180 can include other known connecting elements in addition to the connecting elements described above.

[0061] Figure 3 and Figure 4 Detailed view and cross-sectional view of a first fastening groove according to an embodiment of the present invention.

[0062] There are two ways to fasten the resonator module 100 and the rim 20 of the vehicle wheel according to an embodiment of the present invention.

[0063] A fixing portion (not shown) protruding from the side surface of the resonator module 100 can be formed into a shape corresponding to the shape of the fixing portion so as to accommodate the fixing portion and inserted into a fixing groove (not shown) arranged on one side of the rim 20 to initially couple and fix the resonator module 100 and the rim 20.

[0064] Furthermore, based on the fixing portion and the fixing groove, the vehicle wheel according to one embodiment of the present invention can couple and fix the resonator module 100 and the rim 20 for a second time through the first receiving groove 130 and the second receiving groove 140. The first receiving groove 130 and the second receiving groove 140 receive the tightening belt 50 that pressurizes the resonator module 100 downwardly.

[0065] In more detail, the resonator module 100 may include a first receiving groove 130, which is separated from the two side surfaces of the resonator module 100 by a specified distance along the inner direction. The first receiving groove 130 can accommodate the fastening belt 50 to improve the fastening force between the rim 20 and the resonator module 100. The fastening belt 50 is an additional fastening unit between the rim 20 and the resonator module 100.

[0066] Furthermore, the resonator module 100 may include a second receiving groove 140 engraved from a lower surface of the first receiving groove 130 to receive the stopper 51 of the fastening band 50 .

[0067] The fastening band 50 may be a known unit, such as a metal cable band, but is not limited thereto.

[0068] A portion of the cable tie serving as an additional fastening unit may be inserted into a first receiving groove 130 formed on a side of the resonator module 100 , and a main portion for adjusting the length of the cable tie may be inserted into a second receiving groove 140 .

[0069] Finally, the vehicle wheel according to one embodiment of the present invention can be coupled to the rim 20 and the resonator module 100 via a fixing groove (not shown) and a fixing portion (not shown). A tightening band 50 is additionally provided as a tightening unit for tightening the resonator module 100 to the rim 20 by pressurizing the resonator module 100 downward. In a state where the bottom surface of the resonance space is opened up and directly exposed to the surface of the rim 20, the resonator module 100 may be lifted from the rim 20 due to wind pressure generated by the rotation of the vehicle wheel, thereby reducing the resonance sound cancellation effect. However, the invention of the present application can prevent this phenomenon by using the rim contact portion.

[0070] Furthermore, in this embodiment, the resonator module 100 can have the rim contact portion and the resonating portion 120 formed of an integral fiber material. This reduces weight and minimizes manufacturing costs compared to metal materials such as plastic or aluminum.

[0071] On the other hand, Figure 4 As shown in part (a), the lower surface of the first receiving groove 130 can be formed into a flat surface, such as Figure 4 As shown in part (b) of the figure, the lower surface of the first receiving groove 130 gradually increases in height from the inside to the outside, thereby enhancing the fastening force between the resonator module 100 and the rim 20. More specifically, the fastening band 50 inserted into the first receiving groove 130, which has a flat width, applies pressure vertically below the resonator module 100. Conversely, the fastening band 50 inserted into the first receiving groove 130, which has a gradually increasing height from the inside to the outside, applies pressure in a direction inclined outward from the vertical below the resonator module 100. Ultimately, since the fastening band 50 applies pressure along the bottom of the resonator module 100 while the direction of pressure is inclined outward, the resonator module 100 is maintained in a stretched state, resulting in a more stable connection and fixation between the resonator module 100 and the rim 20.

[0072] Figure 5 FIG. 1 is a detailed diagram of an anti-separation guide member 150 according to an embodiment of the present invention.

[0073] The resonator module 100 may include an anti-separation guide 150 and a spacer 151 .

[0074] The anti-separation guides 150 can be disposed between the two side surfaces of the resonator module 100 and the first receiving groove 130 , and protrude from the upper surface of the resonator module 100 to prevent the fastening band 50 from being separated from the resonator module 100 .

[0075] Furthermore, the anti-separation guide 150 may include an anti-rotation guide (not shown) protruding from an inner side of the anti-separation guide 150 toward the inside of the resonator module 100 to prevent the fastening belt from rotating as the wheel rotates.

[0076] As a result, the fastening band 50 can be more stably fixed to the resonator module 100 , and thus, the fastening force between the rim 20 and the resonator module 100 can be increased.

[0077] Furthermore, at least one of the anti-separation guides 150 disposed on both sides of the resonator module 100 may include a spacer 151 . The spacer 151 may provide a space for extracting and replacing the fastening belt 50 inserted into the first receiving groove 130 by ensuring a remaining space.

[0078] Therefore, when the length of the fastening belt 50 is longer or shorter than the length of the wheel to which it is mounted, the fastening belt 50 is released and its length is adjusted, and then the fastening belt 50 with the adjusted length is reinserted into the resonator module 100 .

[0079] This embodiment is merely an illustrative description of the technical concept of the present invention. Anyone skilled in the art in the technical field to which the present invention belongs can make various modifications and variations to this embodiment without departing from the essential characteristics of the present invention.

[0080] This embodiment is used to illustrate the technical concept of the present invention, rather than to limit the technical concept of the present invention. Therefore, the protection scope of the present invention is not limited to this embodiment.

[0081] The protection scope of the present invention should be interpreted by the protection scope of the invention claims, and all technical ideas within the equivalent or equivalent scope should be interpreted as being included in the protection scope of the present invention.
