Description

Noise elimination device, rim assembly and vehicle

Technical Field

The application relates to the technical field of vehicle structures, in particular to a silencing device, a rim assembly and a vehicle.

Background

With the continuous development of the vehicle industry, the comfort level requirements of users in the driving process are gradually improved, and the tolerance of the users to driving noise is also lower. During running of the vehicle, resonance can be generated between the inside of the tire cavity and excitation of the road surface, so that larger resonance noise is generated, and driving experience of a user is affected.

Next, embodiments of the present specification will be described in detail.

When the vehicle is running, vibrations from the road surface resonate with the air inside the tire, so that a large noise is generated inside the tire. Noise is transmitted to the cabin, reducing the ride experience of the vehicle. To solve this problem, noise reduction can be performed by providing a noise damper such as a sound absorbing cotton on the inner side of the tire or the rim.

When the noise eliminator is arranged on the inner side of the tire, after the tire meets the pricking pin, the tire needs to be locally damaged, so that the noise eliminator is damaged, and the noise reduction effect of the noise eliminator is reduced. This problem can be avoided by fixing the muffler device to the rim. At present, generally adopt the sticky mode to attach the sound absorbing member to the surface of rim, but the installation procedure is loaded down with trivial details, needs heating silence cotton, tear the primer cover paper, align slow circumference laminating, press, and installation effectiveness is lower.

Meanwhile, due to dust accumulation, the sound absorption effect of the sound absorption member is lowered, and the sound absorption member needs to be replaced. When changing, old sound absorption cotton is difficult to clear up, and the outward appearance is ugly to new sound absorption cotton's fixed strength is lower, has the risk of coming off, leads to the noise reduction effect of sound absorber lower. The application provides a muffler device, a rim assembly and a vehicle to solve the above problems.

As shown in fig. 1, a first aspect of the present application provides a muffler device for assembly to a rim 10. The muffler device includes a fixing member 20 and a sound absorbing member 30. The fixture 20 includes an assembly 21, the assembly 21 being removably assembled to the outer surface 11 of the rim 10. The sound absorber 30 is mounted to the assembly 21.

The sound absorbing member 30 is mounted to the outer surface 11 of the rim 10 through the assembly member 21, and is capable of absorbing noise of the vehicle during running, reducing noise of the inside of the vehicle, and improving a riding experience of a user. The assembly 21 is detachably connected with the outer surface 11, so that the sound absorbing member 30 is convenient to disassemble and assemble, and the efficiency in assembly and disassembly is improved. Meanwhile, when the sound absorbing piece 30 is replaced, the assembly piece 21 is directly detached from the rim 10, so that damage to the sound absorbing piece 30 and the mounting structure thereof is avoided, and the fixing effect and the noise reduction effect are ensured.

The mount 20 may be partially detachably connected to the rim 10 and partially fixedly connected to the rim 10. The mount 20 may also be integrally detachably connected to the rim 10. As shown in fig. 1, in one embodiment, the securing member 20 is partially removably attached to the outer surface of the rim 10. The securing member 20 may also include a connector 22 fixedly attached to the outer surface 11, the connector 22 being removably attached to the assembly member 21. The detachable assembly of the sound absorbing member 30 with the rim 10 is achieved by providing the connector 22 on the outer surface 11 of the rim 10 and mounting the sound absorbing member 30 to the assembly 21.

Because the rim 10 can be integrally formed, the outer surface 11 of the rim 10 is fixedly connected with an independent part, the rim 10 is prevented from being machined, the strength of the rim 10 is ensured, extra vibration noise caused by too low strength of the rim 10 is avoided, and the noise reduction effect of the noise elimination device is improved. The manner in which the connector 22 is fixedly attached to the rim 10 is not limited and may be adhesive, welded, etc. The gluing mode is simple, convenient and quick. The welding mode is firm and high in reliability, and the fixing strength of the muffler device can be improved.

The side cut nylon cloth may be used to create a well-aligned barb to grasp the roughened surface such that the first surface 210 and the second surface 220 are tightly adhered together. The structure is convenient to disassemble and assemble, and when the structure is installed, the first surface 210 and the second surface 220 are correspondingly attached. When the assembly 21 is torn away from the connecting piece 22 during disassembly, the connecting piece 22 and the assembly 21 can be separated, so that the disassembly of the sound absorbing piece 30 is completed, the sound absorbing piece 30 and the connecting piece 22 are smooth and free from blocking, and damage to the sound absorbing piece 30 and the connecting piece 22 is avoided. In the case of replacement of the sound absorbing member 30, the new sound absorbing member 30 can still be assembled to the rim 10 relatively firmly, ensuring the noise reduction effect.

Specifically, as shown in fig. 2 and 3, in one embodiment, the first surface 210 is a hook surface, and the second surface 220 is a rough surface. On the assembly 21, a third surface 212 is provided opposite the first surface 210, the third surface 212 being connected to the sound absorber 30. On the connecting member 22, a fourth surface 221 is disposed opposite to the second surface 220, and the fourth surface 221 is connected to the outer surface 11. The first surface 210 may be a roughened surface, the second surface 220 may be a hooked surface, and the specific arrangement of the roughened surface and the hooked surface is not limited.

The head and tail ends of the assembly 21 and/or the connector 22 are connected. At least one of the assembly 21 and the connection member 22 is annular, and the annular head end and tail end are connected to cover the outer surface 11 in the circumferential direction of the rim 10. This arrangement can improve the connection strength between the assembly 21 and the connector 22, and improve the assembly strength of the sound absorbing member 30, thereby ensuring the fixing reliability of the muffler device. In other embodiments, the head and tail ends of the assembly 21 and the connector 22 may not be connected. Which covers only a part of the outer surface 11 and performs a certain sound damping function. To prevent interference with inflation of the tire, corresponding relief holes may be formed in the assembly 21, the connector 22 and the sound absorber 30.

In this embodiment, the assembly member 21 and the connecting member 22 are both annular. The head and tail ends of the assembly 21 are connected. The leading and trailing ends of the connector 22 are also connected. The sound absorbing member 30 may be annular in shape to cover the outer surface 11, improving noise reduction efficiency. In an embodiment in which the number of the assembly members 21 is plural, the number of the sound absorbing members 30 may be plural, and accordingly, assembled to each assembly member 21 to save material. The sound absorbing member 30 may be any noise-eliminating member such as sound absorbing cotton.

As shown in fig. 4 to 6, in other embodiments, the number of the connection members 22 is plural, and the plural connection members 22 are arranged at intervals along a first direction, which may be an axial direction or a circumferential direction of the rim 10. By providing a plurality of the connection members 22, the assembly strength of the sound absorbing member 30 can be improved.

In the embodiment shown in fig. 6, the plurality of connectors 22 form two annular rows. Two annular rows are distributed along the axial direction of the rim 10. Within the same annular row, there are gaps 23 between adjacent connectors 22. The voids 23 in one annular row are aligned with the connectors 22 in the other annular row. The connection members 22 are staggered in the circumferential direction on the outer surface 11, and in the embodiment in which the sound absorbing member 30 is annular, the fixing strength of the sound absorbing member 30 can be improved. In the embodiment in which the number of the sound absorbing members 30 is set to be plural, the plural clearances 23 are provided so as to avoid the working space of the dismounting tool, thereby avoiding damage to the sound absorbing members 30.

The specific number of the connection members 22 is not limited and may be two, three or more. The shape of the connector 22 is not limited and may be rectangular, circular, oval, parallelogram, triangular, pentagram, etc.

In the embodiment where the number of the connecting members 22 is plural, the number of the assembling members 21 may be plural, and the number of the assembling members is the same as the number of the connecting members 22, and the assembling members 21 are aligned with the connecting members 22, so as to save materials and reduce cost. The assembly 21 can also be annular, so that the alignment process during installation is omitted, and the assembly efficiency is improved.

As shown in fig. 7, the mount 20 may also be integrally detachably attached to the rim 10. The fixing member 20 can be engaged with the rim 10 by crimping, screwing, or the like. In one embodiment, the rim 10 and the fixing member 20 are provided with corresponding clamping or screwing structures to achieve connection between the fixing member 20 and the rim 10. In another embodiment, the rim 10 is not provided with redundant structure and the securing member 20 itself is removably attached. When the fixture 20 itself is assembled, the fixture 20 is press-fitted to the outer surface 11 with the fixture 20 being interference-fitted with the rim 10.

Specifically, the assembly 21 may include a plurality of assembly portions 211 detachably connected, and the plurality of assembly portions 211 are fixedly connected and enclose a positioning space 2110 for fixing the rim 10. The assembly 21 may be annular, and the plurality of assembly portions 211 are gradually tightened during the process of mounting the assembly 21 as a whole, and the inner side wall thereof is press-bonded to the outer surface 11, thereby accommodating a part of the structure of the rim 10 in the positioning space 2110.

Alternatively, the dimensions of the positioning space formed by the fixing member 20 are adapted to the dimensions of the rim 10. As shown in fig. 7 and 8, the rim 10 includes a center region 101 and an edge region 102, and the center region 101 has a smaller cross-sectional outer diameter than the edge region 102 in a cross-section perpendicular to the axis of the rim 10. The number of the edge regions 102 is two, the two edge regions 102 are oppositely arranged along the axial direction, and the two ends of the center region 101 are respectively connected with the edge regions 102.

The securing member 20 is located outside the central region 101 axially intermediate the two edge regions 102. At this time, the size of the positioning space 2110 formed by the mount 20 (i.e., the size of the inner diameter of the mount 20) may be equal to or slightly larger than the outer diameter of the center region 101 of the rim 10 and smaller than the outer diameter of the edge region 102 of the rim 10.

In other embodiments, the assembly 21 may also be a resilient integral part, such as: the assembly 21 may be an annular part made of an elastic material such as rubber, and the sound absorbing member 30 is attached to an outer sidewall of the assembly 21. When assembling, the assembly 21 is stretched to expand the annular inner diameter, the assembly 21 is sleeved on the rim 10, the assembly 21 is contracted under the action of elastic force, and the inner side wall of the assembly is tightly attached to the outer surface 11.

As shown in fig. 7, in an embodiment, a side of the assembly portion 211 facing away from the rim 10 is provided with a mounting surface 2111, and the sound absorbing member 30 is assembled to the mounting surface 2111. The installation surface 2111 can be a plane, can provide enough installation area, improves the fixed strength of the sound absorbing member 30, and effectively avoids the sound absorbing member 30 from falling off, thereby ensuring the noise reduction effect of the muffler. The specific structure of the mounting surface 2111 is not limited, and may be a cambered surface or the like. And the like can provide a location for mounting the sound absorbing member 30.

The manner in which the plurality of assembly portions 211 are detachably connected is not limited, and in one embodiment, two ends of the assembly portions 211 are provided with the clamping structures 2112, and the plurality of assembly portions 211 are clamped and fixed by the clamping structures 2112. The fastening structure 2112 is easy to assemble and disassemble, and can improve the installation efficiency. In other embodiments, screw structures or the like may be provided at both ends of the assembly portion 211.

The specific configuration of the engagement structure 2112 is not limited, and the plurality of assembly portions 211 may be fixed to each other. For example: in an embodiment, one of the two ends of the assembly portion 211 may be a buckle, and the other end may be a slot. In this embodiment, the plurality of assembled portions 211 may be rotationally symmetrical about the axis of the rim 10. After one of the plurality of assembly parts 211 rotates by a certain angle, the clamping groove on the assembly part 211 can reach the position where the other assembly part 211 is clamped, and the two assembly parts are clamped. This arrangement allows the plurality of assembling portions 211 to have the same structural form, and reduces the mold development cost. Specifically, in the embodiment shown in fig. 7, the two assembly portions 211 are centrosymmetric. One of the pair of assembly portions 211 may be rotated 180 to coincide with the other.

In other embodiments, the plurality of assembling portions 211 may be divided into two groups. The two ends of the first group of assembling parts 211 are all buckles, and the two ends of the second group of assembling parts 211 are all clamping grooves. The plurality of assembling portions 211 are arranged in order of one first group and one second group. In an embodiment, the number of the assembling portions 211 is two, wherein two ends of one assembling portion 211 are both buckles, and two ends of the other assembling portion 211 are both clamping grooves. Since the structures of both ends of the single assembly portion 211 are identical, the assembly error between both ends of the assembly portion 211 and the other assembly portion 211 does not occur when the assembly is performed, and the assembly efficiency is improved.

The material of the assembly portion 211 is not limited, and since the assembly portion 211 needs to be pressed against the outer surface 11, the material of the assembly portion 211 needs to have elasticity itself. For example: the material of the assembly portion 211 may be plastic, carbon fiber, or the like. The material has elasticity and light weight, and can meet the light weight requirement of the muffler device. Because the assembly part 211 has lighter weight, the assembly part is not easy to shake when being fixed on the rim 10, thereby avoiding

The self vibration of the assembly portion 211 generates noise, reduces noise transmitted into the vehicle cabin, and further improves the riding experience of the user.

The number of the assembling parts 211 is not limited and may be two, three or more. When the number of the assembly portions 211 is small, since the number of parts to be assembled is small, the assembly efficiency can be improved. When the number of the assembly portions 211 is large, the number of the positions of the assembly portions 211 to be engaged with each other is large in the assembly 21, and the mounting strength of the assembly 21 can be improved, so that the mounting strength of the muffler device can be improved, and the fixing reliability of the muffler device can be improved.

As shown in fig. 1, a rim assembly according to a second aspect of the present application includes a rim 10 and the above-described muffler device. Because the noise elimination assembly has the function of reducing noise, the rim assembly can also play a role in improving resonance noise.

The rim 10 includes a pair of side surfaces 12 and an outer surface 11 connecting the pair of side surfaces 12, and the fixing member 20 further includes a plurality of connecting members 22 fixed to the outer surface 11 with spaces 23 between the plurality of connecting members 22. At least one of the pair of side surfaces 12 is provided with an indication mark 121, and the indication mark 121 is provided near the gap 23 for indicating the working position of the dismounting tool.

When the tire 40 is attached and detached, an attaching and detaching tool is engaged between the tire 40 and the gap of the rim 10, and the tire 40 is pried out of the rim 10. In this process, the disassembly tool needs to be extended into the interior of the tire 40, possibly causing damage to the sound absorbing member 30. By providing a plurality of connectors 22, there are voids 23 in adjacent connectors 22. In this embodiment, the assembly 21 and the sound absorbing member 30 may be disposed in plural numbers, and aligned with the connecting member 22 respectively. Extending the disassembly tool to the gap 23 can avoid damage to the sound absorbing member 30 by the disassembly tool.

The indication mark 121 may be provided on only one side 12, which is the most commonly used side for mounting and dismounting the vehicle, toward the outside of the vehicle, which can reduce the difficulty in processing the rim assembly. The indication marks 121 may be provided on both sides of the rim 10, and serve as indication on both sides. In the embodiment shown in fig. 5, the indicator marks 121 on the pair of side surfaces 12 are oppositely disposed. In the embodiment shown in fig. 6, the indicators 121 on a pair of sides 12 are staggered. The number of the indication marks 121 is not limited, and one indication mark 121 may be provided near each of the gaps 23, or the indication marks 121 may be provided near a part of the gaps 23.

The indication mark 121 is not limited to a triangle, and a vertex of the triangle points to the connection between the outer surface 11 and the side 12 of the rim 10, so as to inform a worker that the disassembly tool is extended from the vertex. The indication mark 121 may be any arrow-shaped or diamond-shaped pattern with a pointing meaning.

The specific number and distribution of the indication marks 121 is not limited, and may be at least partially disposed near the space 23. In embodiments where the connector 22 is annular, the removal tool may also be retracted by reducing the annular width. That is, the length of the connecting member 22 in the axial direction of the rim 10 is reduced, and a certain space for avoiding is provided on the outer surface 11 on both sides of the connecting member 22, so that the connecting member is left for the dismounting tool to operate, thereby preventing damage to the sound absorbing member 30.

A third aspect of the present application provides a vehicle comprising the rim assembly described above and a tire 40 mounted to the rim assembly. The types of vehicles are not limited, and may be fuel automobiles, hybrid automobiles, electric automobiles, and the like.

Because foretell rim subassembly has better noise reduction effect, the noise in the carriage of this application vehicle is less, has improved user's driving experience. Noise generated by resonance and the like in the tire 40 is absorbed by the sound absorbing member 30, noise of the tire 40 is reduced, and noise transmitted to the vehicle cabin is also reduced.
