DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In order to make the technical solutions and advantages of this application clearer, the following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Figure 1-4 The rim, a method for manufacturing the rim, a vehicle, and the like are described in detail.

[0042] Due to the rapid development of the automobile industry, people have higher and higher requirements for the riding comfort of automobiles. The driving noise generated by the wheels of automobiles has always been a difficult problem to solve. For a long time, people have used tire materials with moderate hardness and tread patterns to reduce noise, but have not been able to completely solve the problem of driving noise. Therefore, in order to better achieve wheel noise reduction, many automobile companies will set a layer of sound-absorbing sponge on the outer surface of the rim to achieve noise reduction.

[0043] However, the current solution for laying a layer of sound-absorbing sponge is generally to fix the sound-absorbing sponge and the rim by bonding. However, when the vehicle is running, the rim will be in a high-speed rotation state for a long time, and the sound-absorbing sponge on the rim is easily fallen off due to the centrifugal force.

[0044] The present application provides a rim, such as Figure 1 and Figure 2 As shown, the rim may include a rim body 1 and a noise reduction component 2; the noise reduction component 2 is continuously wound around the rim body 1 in a spiral shape along the circumference of the rim body 1, and is at least partially connected to the outer peripheral wall 11 of the rim body 1, and the number of turns of the noise reduction component 2 wound around the outer peripheral wall 11 = i, i is greater than or equal to 3; wherein the noise reduction component 2 is used to absorb at least part of the noise in the environment in which the rim body 1 is located, and absorb at least part of the vibration generated by the rim body 1.

[0045] In the rim provided in the embodiment of the present application, a noise reduction component 2 is wound around the outside of the rim body 1, and the noise reduction component 2 can absorb at least part of the noise transmitted from the rim body 1 to the noise reduction component 2, so as to reduce the driving noise generated by the tires of the vehicle during driving, thereby improving the NVH performance of the entire vehicle, so that users can have a better riding experience when riding; at the same time, in the rim provided in the present application, the noise reduction component 2 is wound around the circumference of the rim body 1 for multiple turns. Compared with the rim with a layer of sound insulation cotton in the related technology, the noise reduction component 2 can offset part of the centrifugal force through its own structural force during the rotation of the rim, thereby reducing the risk and probability of the noise reduction component 2 falling off, and ensuring the connection stability between the noise reduction component 2 and the rim body 1.

[0046] In addition, in the related art, the sponge of the rim must be provided with at least one gap 23 to avoid the air nozzle, which causes the total volume of the sponge to decrease and the noise reduction effect to decrease. The noise reduction component 2 in the present application is spirally wound around the rim body 1 for multiple turns, and can be wound from a position close to the air nozzle as a starting point, and can wrap around the outer peripheral wall 11 of the rim body 1 to the maximum extent, further improving the noise reduction effect.

[0047] It should be noted that the noise reduction component 2 provided in the embodiment of the present application has a noise reduction function. On the one hand, through its own elastic properties, it can absorb part of the vibration on the rim body 1 when the rim body 1 rotates, thereby reducing the vibration noise transmitted to the interior of the vehicle; on the other hand, through its own special structure, it can reflect the noise in the environment back and forth inside it, weaken the energy of the noise, and thus achieve the effect of noise reduction.

[0048] In some embodiments, the noise reduction element 2 may be an elastic member having a loose porous structure.

[0049] Optionally, the noise reduction element 2 includes one or a combination of at least two of polyurethane sponge, foamed plastic and polyurethane foam. Those skilled in the art can select and adjust according to actual needs, manufacturing difficulty, manufacturing cost and other aspects.

[0050] Optionally, the width of the noise reduction member 2 is 10 to 30 mm.

[0051] In the related art, in order to improve the noise reduction effect, the width and length of the sound-absorbing sponge need to be adapted to the gear of the rim, but different types of rims have different specifications and sizes. In order to adapt to various types of rims, it is necessary to produce sound-absorbing sponges of various specifications. As a result, there will be problems of low efficiency and more inventory in the production process.

[0052] Therefore, in the rim provided by the embodiment of the present application, the width of the noise reduction member 2 is between 10 and 30 mm, which is narrower than the conventional sound-absorbing sponge. For rims of different sizes, the number of windings of the noise reduction member 2 can be changed according to actual needs to completely cover the outer peripheral wall 11 of the rim body 1. In other words, only one noise reduction member 2 of a certain width specification needs to be produced to adapt to most rim widths, which can effectively reduce the types of materials, and has better adaptability than the sound-absorbing sponge with a larger width in the related art, and can reduce the manufacturing cost of the noise reduction rim.

[0053] Furthermore, the noise reduction member 2 provided in the embodiment of the present application has a relatively small width and can be freely combined when being wound, thereby wrapping around the outer peripheral wall 11 of the rim body 1 to the maximum extent, thereby being able to better absorb noise.

[0054] In some embodiments of the present application, the rim includes a first functional component 3 , which is connected between the noise reduction component 2 and the rim body 1 to absorb at least part of the vibration transmitted from the rim body 1 to the noise reduction component 2 .

[0055] When the vehicle is driving, part of the driving noise generated by the tires will be transmitted to the rims, and this part of the noise may be transmitted to the interior of the vehicle through the rims, thereby causing excessive noise inside the vehicle and a poor riding experience for users.

[0056] In the rim provided in the embodiment of the present application, in order to further reduce the noise transmitted to the interior of the vehicle, as Figure 3 As shown, a first functional component 3 can be further arranged between the outer peripheral wall 11 of the rim body 1 and the noise reduction component 2, wherein the first functional component 3 not only has a fixing function, which can realize the fixed connection between the rim body 1 and the noise reduction component 2, but also has the performance of a damping layer, which can absorb at least part of the vibration generated on the rim body 1; that is, the rim provided in the embodiment of the present application, by arranging the first functional component 3 and the noise reduction component 2, achieves a double weakening of the noise transmitted from the rim body 1 to the interior of the vehicle, thereby achieving a better noise reduction effect and improving the NVH performance of the entire vehicle.

[0057] In some embodiments, the first functional component 3 may include a damping layer and an adhesive layer, wherein an adhesive layer is disposed on both sides of the damping layer, and the two adhesive layers are respectively connected to the rim body 1 and the noise reduction component 2, wherein the damping layer is a component with elastic deformation function.

[0058] Although this arrangement has better noise reduction performance, it requires a damping layer, which results in high manufacturing cost and complicated manufacturing process, making it unsuitable for mass production. In this regard, the first functional component 3 can be a component having both the functions of a damping layer and an adhesive layer.

[0059] Optionally, the first functional part 3 is butyl rubber. Butyl rubber not only has good bonding performance, and can realize the fixed connection between the rim body 1 and the noise reduction part 2, but also can undergo certain elastic deformation when subjected to force, and can absorb part of the vibration; the use of butyl rubber not only takes into account the noise reduction performance of the rim, but also reduces the production cost and manufacturing difficulty, and can meet the work requirements of mass production.

[0060] In some embodiments of the present application, multiple circles of noise reduction components 2 are spirally wound around the outer peripheral wall 11, and a gap 23 is provided between any circle of noise reduction components 2 and an adjacent circle of noise reduction components 2; the rim also includes a second functional component, which is located in the gap 23 and is respectively connected to the two adjacent circles of noise reduction components 2 and fills the gap 23. The second functional component is used to absorb at least part of the vibration transmitted from the rim body 1 to the noise reduction component 2.

[0061] According to the above embodiment, the noise reduction component 2 is spirally sleeved on the outer peripheral wall 11 of the rim body 1. Therefore, when the noise reduction component 2 is wound, due to the problem of process precision, a gap 23 may appear between two adjacent circles of the noise reduction component 2, which is equivalent to reducing the coverage area of ​​the noise reduction component 2, which will affect the noise reduction effect of the rim.

[0062] In the rim provided in the embodiment of the present application, Figure 4 As shown, after the noise reduction component 2 is wound, a second functional component can be filled in multiple gaps 23 to absorb at least part of the vibration on two adjacent circles of the noise reduction component 2, thereby improving the overall noise reduction effect of the rim.

[0063] Optionally, the second functional part is butyl rubber. Butyl rubber can not only undergo a certain elastic deformation when subjected to force and absorb some vibration, but also has good bonding performance, which can achieve bonding connection between two adjacent circles of noise reduction components 2, improve the connection stability of the noise reduction components 2, and prevent them from falling off when the rim rotates at high speed.

[0064] In some embodiments of the present application, from the first circle to the i-th circle, the noise reducing members 2 are arranged in sequence along the axial direction of the rim body 1, and the noise reducing members 2 of two adjacent circles are partially overlapped. That is, from the first circle to the i-th circle, for any circle of noise reducing members 2, they will partially overlap with the noise reducing members 2 of the next circle when winding, that is, the noise reducing members 2 of the next circle will press the noise reducing members 2 of the previous circle, and then the noise reducing members 2 of the previous circle can be fixed by the noise reducing members 2 of the next circle. This arrangement makes the connection between the noise reducing members 2 and the rim body 1 more tightly, further reducing the risk of the noise reducing members 2 falling off when the rim body 1 rotates at high speed.

[0065] In addition, with this arrangement, since each circle of noise reduction components 2 has the function of pressing and fixing the previous circle of noise reduction components 2, the area of ​​the connecting components between the noise reduction components 2 and the rim body 1 can be reduced. For example, only the two ends of the noise reduction components 2 along the length direction can be fixed.

[0066] In some embodiments, the rim may further include a first fixing member, which fixes the first end 21 of the noise reduction member 2 on the peripheral wall 11; and / or, the rim may further include a second fixing member, which fixes the second end of the noise reduction member 2 on the peripheral wall 11, and the first end 21 and the second end 22 are opposite ends of the noise reduction member 2 along the length direction.

[0067] In the rim provided in the embodiment of the present application, the first end 21 and the second end 22 of the noise reducing member 2 can be fixed by setting a first fixing member and a second fixing member, so as to meet the fixing requirements of the noise reducing member 2 in the above embodiment. The first fixing member and the second fixing member can be adhesives, tapes and other components with bonding functions, and those skilled in the art can select and adjust according to actual needs.

[0068] In addition, for the above-mentioned embodiment in which the first functional part is set between the noise reduction component 2 and the rim body 1, a first fixing component and a second fixing component can also be further set on this basis to reinforce and fix the first end 21 and the second end 22 of the noise reduction component 2, thereby further reducing the risk and probability of the noise reduction component 2 falling off.

[0069] However, in this arrangement, both ends of the noise reducing member 2 along the length direction are still exposed in the space between the rim body 1 and the tire. In some embodiments, the noise reducing member 2 includes a first end 21 and a second end 22 opposite to each other along the length direction, and the noise reducing member 2 is arranged around the rim body 1 from the first end 21 to the second end 22; at least a portion of the first end 21 extends between the next circle of the noise reducing member 2 and the peripheral wall 11; and / or at least a portion of the second end 22 extends between the previous circle of the noise reducing member 2 and the peripheral wall 11.

[0070] In the rim provided in the embodiment of the present application, the front and rear ends of the noise reduction component 2 can also be inserted between the noise reduction component 2 of the middle circle and the outer peripheral wall 11 of the rim body 1, that is, the first end 21 and the second end 22 are reinforced and fixed by the noise reduction component 2 of the middle circle to prevent the front and rear ends of the noise reduction component 2 from falling off when the rim body 1 rotates at high speed, thereby reducing the risk and probability of the noise reduction component 2 falling off.

[0071] The present application also provides a method for manufacturing a rim, which is applied to the above-mentioned rim, and the manufacturing method comprises:

[0072] S100, cleaning the outer peripheral wall 11 of the rim body 1, and placing the cleaned rim body 1 on a workbench that can rotate it around an axis;

[0073] It should be noted that during cleaning, it is necessary to ensure that there is no water and dust on the outer peripheral wall 11 of the rim body 1 after cleaning. The rim body 1 can be cleaned with a dry cloth.

[0074] S200, connecting the noise reduction member 2 to one side of the valve or the controller on the rim body 1, and spirally winding the noise reduction member 2 around the rim body 1 according to a set pitch;

[0075] Optionally, the thread pitch is 30 mm.

[0076] S300 , compacting the noise reduction component 2 .

[0077] It should be noted that during the compaction operation, the noise reduction components 2 at the head and tail ends may be compacted first, and then the remaining noise reduction components 2 may be compacted to ensure that each section of the noise reduction component 2 is tightly connected to the rim body 1 .

[0078] The present application also provides a vehicle, which comprises the above-mentioned rim.

[0079] In the vehicle provided in the embodiment of the present application, a noise reduction component 2 is wound around the outside of the rim body 1. The noise reduction component 2 can absorb at least part of the noise transmitted from the rim body 1 to the noise reduction component 2, so as to reduce the driving noise generated by the tire during the driving of the vehicle, thereby improving the NVH performance of the whole vehicle, so that the user has a better riding experience when riding; at the same time, in the rim provided by the present application, the noise reduction component 2 is wound around the circumference of the rim body 1 for multiple turns. Compared with the rim with a layer of sound insulation cotton attached in the related art, the noise reduction component 2 has its own structure during the rotation of the rim The structural force can offset part of the centrifugal force, which can reduce the risk and probability of the noise reduction component 2 falling off, and ensure the stability of the connection between the noise reduction component 2 and the rim body 1; in addition, the rim in the related technology must have at least one gap 23 in the sponge to avoid the air nozzle, which causes the total volume of the sponge to decrease and the noise reduction effect to decrease. The noise reduction component 2 in the present application is spirally wound around the rim body 1 for multiple turns, and can be wound from a position close to the air nozzle as a starting point, which can wrap around the outer peripheral wall 11 of the rim body 1 to the maximum extent, further improving the noise reduction effect.

[0080] Furthermore, according to multiple tests, the vehicle provided in the embodiment of the present application, due to the use of the above-mentioned rim, can reduce the overall noise by 6-6.5 decibels compared to a vehicle without the noise reduction component 2, and can improve the noise reduction effect by 10%-20% compared to a vehicle with a sound-absorbing sponge attached to the rim.

[0081] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.
