Description

[Technical Field]

[0001] The present disclosure relates to an interior member and a vehicle including the interior member. [Background technology]

[0002] Conventionally, an interior member is known that is attached to a body member having a vent hole and covers the vent hole. The vent hole penetrates from the exterior of the body member to the interior of the vehicle and allows gas inside the vehicle to be exhausted to the outside.

[0003] In such interior components, sound-absorbing material is placed around the vent hole through which gas flows (see, for example, Patent Document 1). In the interior component of Patent Document 1, the sound-absorbing material absorbs noise transmitted from outside the vehicle through the vent hole, reducing noise transmitted into the vehicle cabin.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-016809 Summary of the Invention [Problem to be solved by the invention]

[0005] In such interior components, the sound-absorbing material absorbs noise transmitted from outside the vehicle through the vent holes. Therefore, the amount of noise that can be absorbed may be limited depending on the size of the sound-absorbing material. As a result, there is a risk that the noise transmitted from outside the vehicle through the vent holes may not be sufficiently reduced.

[0006] An object of the present disclosure is to provide a new interior member that can easily reduce noise transmitted into the interior of a vehicle. [Means for solving the problem]

[0007] The interior member according to the present disclosure can be attached to a body member having a vent hole for discharging gas from inside the vehicle cabin to the outside. The interior member includes a standing wall and a communication hole. The standing wall extends from an opposing surface facing the body member toward the body member and abuts against the body member to form a space between the opposing surface and the body member. The communication hole is provided in the opposing surface and connects the space to the vehicle cabin.

[0008] According to this interior member, a space partitioned by a vertical wall is formed between the opposing surface of the interior member and the body member. This makes it possible to reduce noise transmitted from the outside of the vehicle through the vent hole within the space. As a result, noise transmitted into the vehicle cabin can be reduced. [Effects of the Invention]

[0009] According to the present disclosure, a novel interior member that can easily reduce noise transmitted into the interior of a vehicle can be provided. [Brief explanation of the drawings]

[Figure 5] FIG. 10 is a cross-sectional view of an interior member according to another embodiment of the present disclosure. DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. Fig. 1 is a schematic diagram showing a vehicle C in this embodiment. Fig. 2 is a schematic diagram showing a state in which an interior member 1 in this embodiment is attached to a body member B. The up-down direction G shown in Figs. 1 to 4 does not necessarily coincide with the direction of gravity.

[0012] As shown in FIGS. 1, 2, and 3, the interior member 1 of this embodiment is a molded resin member that can be attached to a body member B of a vehicle C. The body member B of the vehicle C has a vent duct (an example of a vent hole) Vi. The vent duct Vi exhausts gas from the interior compartment R of the vehicle C to the outside. In this embodiment, the body member B constitutes the vehicle body at the rear side of the vehicle C. The vent duct Vi connects the inside of the body member B in the width direction W to the outside, i.e., the interior compartment R of the vehicle C to the outside. The vent duct Vi includes a door (e.g., a rubber butterfly valve) Vd that rotates outward around an opening / closing axis Vo, and opens and closes depending on the difference between the internal pressure of the interior compartment R and the atmospheric pressure outside the vehicle C. When the internal pressure of the interior compartment R becomes greater than the atmospheric pressure outside the vehicle C due to the opening or closing of a door of the vehicle C (not shown), the door Vd opens and the vent duct Vi exhausts gas from the interior compartment R to the outside of the vehicle C. On the other hand, particularly when the vent duct Vi is in an open state, environmental noise outside the vehicle C and exhaust noise from the vehicle C are likely to be transmitted to the interior R via the vent duct Vi.

[0013] The interior member 1 includes a standing wall 2, a communication hole 4, and an opposing surface 6. The interior member 1 of this embodiment is a quarter trim that is attached to the rear side of the interior R of a vehicle C. The interior member 1 is a molded resin member that is molded to a predetermined thickness, and is attached to a body member B of the vehicle C to form the design surface of the interior R. The surface of the interior member 1 opposite the interior R and the surface of the body member B are disposed apart from each other. Therefore, a space is formed between the interior member 1 and the body member B excluding the attachment position.

[0014] The interior member 1 of this embodiment is disposed on a side surface of the interior compartment R of a vehicle C. The interior member 1 is disposed across a floor portion B1 of a body member B extending in the vehicle width direction W and a side wall portion B2 of the body member B extending in the up-down direction G. The lower portion of the interior member 1 is fixed in place with a flange 8 formed at the lower end of the opposing surface 6 abutting against the floor portion B1. The upper portion of the interior member 1 is fitted with and fixed to an inner panel I disposed closer to the interior compartment R than the body member B. The mounting position and shape of the interior member 1 can be changed in various ways depending on the shape of the body member B and the design of the interior compartment R. The interior member 1 may be fixed using bolts, clips, tapping screws, or the like.

[0015] 3 is a cross-sectional view showing the cross section AA of FIG. 2 in this embodiment. As shown in FIGS. 2 and 3 , the standing wall 2 stands from an opposing surface 6 that faces the surface of the body member B on the interior R side toward the body member B. In this embodiment, the standing wall 2 is a rib that stands toward the outside in the vehicle width direction W of the vehicle C. Furthermore, when the interior member 1 is attached to the body member B, an end portion 20 of the standing wall 2 abuts against the body member B. As a result, the standing wall 2 forms a space S between the opposing surface 6 and the body member B. In this embodiment, the standing wall 2 is formed integrally with the interior member 1, stands approximately perpendicular from the opposing surface 6 toward the body member B, and the end portion 20 is in surface contact with the body member B. Furthermore, the length by which the standing wall 2 stands toward the body member B may be changed depending on the distance between the opposing surface 6 and the body member B.

[0016] FIG. 4 is a schematic diagram showing the shapes of the standing wall 2 and the communication hole 4 in the vehicle width direction W. As shown in FIGS. 2, 3, and 4, the standing wall 2 includes a first standing wall 21, a second standing wall 22, and a third standing wall 23. The first standing wall 21 and the second standing wall 22 are a pair of standing walls arranged on either side of the communication hole 4, which will be described later. In this embodiment, the first standing wall 21 and the second standing wall 22 extend in the up-down direction G from the lower part of the interior member 1. The third standing wall 23 extends in the front-rear direction F of the vehicle C and connects the first standing wall 21 and the second standing wall 22. That is, in this embodiment, the standing wall 2 is a generally U-shaped standing wall formed on the opposing surface 6 by the first standing wall 21, the second standing wall 22, and the third standing wall 23.

[0017] The communication hole 4 is provided in the lower part of the opposing surface 6, and communicates the space S with the interior R of the vehicle C. In this embodiment, the communication hole 4 is formed including a louver (not shown), and has a generally rectangular shape extending in the front-rear direction F. The shape of the communication hole 4 may be changed in various ways depending on the design of the interior member 1 and the interior R. The communication hole 4 is arranged near the lower end of the interior member 1.

[0018] Moreover, the interior member 1 of this embodiment is provided with opening walls 4a that stand upright on the outer periphery of the communicating hole 4 toward the body member B. Unlike the standing walls 2, the opening walls 4a are formed to extend to positions where they do not abut against the body member B, and stand upright on the front, rear, top and bottom of the communicating hole 4 to surround the communicating hole 4.

[0019] The lower end of the communication hole 4 is disposed at the same height as or higher than the lower ends of the first standing wall 21 and the second standing wall 22 in the vertical direction G. The lower ends of the first standing wall 21 and the second standing wall 22 are disposed below the lower edge of the communication hole 4, extend to at least the same height as the flange 8, and abut against the floor portion B1 of the body member B. As shown in FIG. 2 , the communication hole 4 is disposed opposite the vent duct Vi. That is, the communication hole 4 and the vent duct Vi are disposed so as to overlap in the vehicle width direction W of the vehicle C. In this embodiment, the communication hole 4 and the vent duct Vi are disposed so as to substantially overlap in the vehicle width direction W of the vehicle C. Note that the lower end of the communication hole 4 may be disposed at the same height as the lower ends of the first standing wall 21 and the second standing wall 22 in the vertical direction G. In this case, the lower wall of the opening wall 4a may not be provided. In this case, the floor portion B1 functions as the opening wall 4a disposed below the communication hole 4.

[0020] The interior member 1 formed in this manner forms a space S in an area surrounded by the standing wall 2, the floor portion B1, and the body member B. When the vent duct Vi is closed, the space S is a closed space except for the communication holes 4. When the vent duct Vi is closed, the space S is closed by the standing wall 2 and the floor portion B1 except for the communication holes 4, and a space S of a predetermined volume is formed between the vent duct Vi and the communication holes 4. The space S communicates with the interior R of the vehicle C via the communication holes 4. When the vent duct Vi is open, the space S communicates with the outside of the vehicle C via the vent duct Vi and with the interior R via the communication holes 4. In other words, the space S has a passage provided below it that communicates with the interior R of the vehicle C and the outside, and functions as an expansion chamber (chamber) that extends above the passage and surrounds the periphery of the passage with a closed space. That is, the interior member 1 forms a space S with the standing wall 2, the body member B, and the floor portion B1, thereby forming a passage that connects the vent duct Vi to the communication hole 4 on the opposite side of the design surface, and an expansion-type silencer formed integrally with this passage. Note that the communication hole 4 may be provided with an opening wall 4a as in this embodiment in order to obtain a higher sound-absorbing effect.

[0021] As a result, noise propagated from the outside of the vehicle C through the vent duct Vi is transmitted from the vent duct Vi to the communication hole 4 via the space S. At this time, the noise propagated from the vent duct Vi enters the space S and is reflected by the standing wall 2. The reflected noise interferes with the noise entering the space S and is attenuated. Therefore, the noise that enters the space S is attenuated before it reaches the communication hole 4. As a result, the interior member 1 can reduce noise propagated into the interior R of the vehicle C. In this embodiment, the noise reflected by the standing wall 2 is further reflected by the opening wall 4a. This further enhances the sound deadening effect. The volume of the space S and the flow area C2 of the communication hole 4, which will be described later, may be determined based on the frequency of the noise.

[0022] Furthermore, in this embodiment, the flow area C1, which is the area through which gas flows in the communication hole 4, is equal to or larger than the flow area C2, which is the area through which gas flows in the vent duct Vi. This makes it possible to reduce noise without impeding the flow of gas between the interior R of the vehicle C and the outside.

[0023] As described above, according to the present disclosure, a novel interior member 1 that can easily reduce noise transmitted to the interior R of the vehicle C can be provided.

[0024] <Other embodiments> Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above embodiments, and various modifications are possible without departing from the spirit of the invention.

[0025] (a) In the above embodiment, the interior member 1 was the quarter trim of the vehicle C, but the present disclosure is not limited to this. That is, the position at which the interior member 1 is attached can be changed in various ways inside the interior R of the vehicle C. For example, the interior member 1 may be an interior member that forms part of the design of the luggage compartment of the vehicle C. The vent duct Vi may open into the space between the body member B and a plastic bumper attached to the rear of the vehicle C, and communicate with the outside of the vehicle C.

[0026] (b) In the above embodiment, the standing wall 2 is provided standing continuously from the opposing surface 6 of the interior member 1 toward the body member B, but the present disclosure is not limited to this. That is, as shown in Fig. 5, a molded member 24 made of a foam material or the like may be attached to the end of the standing wall 2 on the body member B side, and may abut against the body member B.

[0027] (c) In the above embodiment, the standing wall 2 is generally U-shaped and formed by the first standing wall 21 to the third standing wall 23, but the present disclosure is not limited to this. That is, the standing wall 2 may surround the communication hole 4 to define the space formed between the interior member 1 and the body member B. For example, a fourth standing wall may be provided below the communication hole 4, extending in the fore-and-aft direction F of the vehicle C and connecting to the first standing wall 21 and the second standing wall 22, to surround the communication hole 4.

[0028] (d) In the above embodiment, the space S is a generally rectangular parallelepiped space partitioned by the standing wall 2 and the floor portion B1, but the present disclosure is not limited to this. That is, the space S may be partitioned into a closed space by the standing wall 2 and the body member B, and the shape of the space S may be changed in various ways depending on the shapes of the interior member 1 and the body member B.

[0029] (e) In the above embodiment, the opening wall 4a is provided on the outer periphery of the communication hole 4, but the opening wall 4a may be omitted. [Explanation of symbols]
