Summary of the Invention

Problems to be Solved by the Invention

[0004] However, for a seal structure (noise leakage suppression structure) for reducing noise transmitted from an engine compartment of a vehicle (in the case of an electric vehicle or the like, a motor is accommodated instead of an engine, but in that case it is also referred to as an "engine compartment": the same applies hereinafter) to a vehicle cabin, there may be a case where a gap (a gap that causes noise leakage) for passing various cables routed in the engine compartment has to be provided, so there is still room for improvement.

[0005] Therefore, an object of the present invention is to obtain a seal structure capable of reducing noise transmitted from an engine compartment to a vehicle cabin even when a gap for passing a cable is provided.

Means for Solving the Problems

[0006] To achieve the above objective, the first embodiment of the present invention provides a sealing structure that is provided to seal a gap that occurs in the engine compartment of a vehicle when viewed from the front-rear direction of the vehicle and has a notch for forming a gap for passing a cable, and a sound-absorbing chamber formed inside the sealing member, with an opening provided on the bottom surface of the notch.

[0007] According to the first embodiment of the invention, a sealing member is provided to seal a gap that occurs in the engine compartment of a vehicle when viewed from the front or rear direction of the vehicle. The sealing member has a notch for forming a gap through which a cable passes, and a sound-absorbing chamber with an opening is formed inside the sealing member at the bottom surface of the notch. Therefore, even though a gap for passing a cable is provided by the notch, at least a portion of the noise passing through that gap enters the sound-absorbing chamber through the opening and is absorbed. As a result, the noise transmitted from the engine compartment to the passenger compartment is reduced.

[0008] Furthermore, a second embodiment of the seal structure according to the present invention is the seal structure according to the first embodiment, wherein the notch is a recess formed in the shape of a "U".

[0009] According to the second embodiment of the invention, the notch is formed as a recess in the shape of a "U". Therefore, it is easy to pass a cable through the gap provided by the recess. In this invention, the "U" shape also includes a roughly "U" shape. Furthermore, even though a gap for passing a cable is provided by the recess, at least a portion of the noise passing through that gap enters the sound-dampening chamber from the opening and is silenced, thus reducing the noise transmitted from the engine compartment to the passenger compartment.

[0010] Furthermore, a third embodiment of the seal structure according to the present invention is a seal structure according to the first or second embodiment, wherein the sound-absorbing chamber is formed perpendicular to the bottom surface.

[0011] If the sound-dampening chamber is not formed perpendicular to the bottom surface of the notch (recess), some sound waves (noise) will be reflected at the curved portion, making it impossible to efficiently guide the noise (sound waves) into the sound-dampening chamber.

[0012] According to the third embodiment of the invention, since the sound-dampening chamber is formed perpendicular to the bottom surface of the notch (recess), at least a portion of the noise passing through the gap provided by the notch (recess) is efficiently guided into the sound-dampening chamber compared to the case where the sound-dampening chamber is not formed perpendicular to the bottom surface of the notch (recess). Therefore, at least a portion of the noise is effectively dampened.

[0013] Furthermore, the fourth aspect of the sealing structure according to the present invention includes a sealing member provided to seal a gap that occurs in the engine compartment of a vehicle when viewed from the front-rear direction of the vehicle, and having a recess for forming a gap for passing a cable, and a plurality of sound-dampening chambers formed inside the sealing member, with openings provided on the bottom surface and side surface of the recess, respectively.

[0014] According to the fourth aspect of the invention, a sealing member is provided to seal a gap that occurs in the engine compartment of a vehicle when viewed from the front-rear direction of the vehicle. The sealing member has a recess for forming a gap through which a cable passes, and a plurality of sound-absorbing chambers are formed inside the sealing member, each having an opening on the bottom and side of the recess. Therefore, even though a gap for passing a cable is provided by the recess, at least a portion of the noise passing through that gap enters each sound-absorbing chamber through each opening and is silenced. As a result, the noise transmitted from the engine compartment to the passenger compartment is reduced.

[0015] Furthermore, a fifth aspect of the seal structure according to the present invention is a seal structure according to the fourth aspect, wherein the plurality of sound-absorbing chambers are each formed perpendicular to the bottom surface and the side surface.

[0016] Here, when each soundproof chamber is not formed perpendicular to the bottom surface and the side surface of the recess, in each bent portion, some sound waves (noise) are reflected, and the noise (sound waves) cannot be efficiently guided into the soundproof chamber.

[0017] According to the invention of the fifth aspect, since each soundproof chamber is formed perpendicular to the bottom surface and the side surface of the recess, at least a part of the noise passing through the gap provided by the recess is efficiently guided into each soundproof chamber as compared with the case where each soundproof chamber is not formed perpendicular to the bottom surface and the side surface of the recess. Therefore, at least a part of the noise is effectively soundproofed.

Effect of the Invention

[0018] As described above, according to the present invention, even if a gap for passing a cable is provided, the noise transmitted from the engine compartment to the passenger compartment can be reduced.

Best Mode for Carrying Out the Invention

[0020] Hereinafter, embodiments of the present invention will be described in detail based on the drawings. For the sake of convenience in explanation, in each figure, the arrow UP appropriately shown is the upward direction of the vehicle, the arrow RE is the rearward direction of the vehicle, and the arrow RH is the rightward direction of the vehicle. Therefore, in the following description, when the directions of up and down, front and rear, and left and right are described without special mention, they indicate up and down, front and rear, and left and right in the vehicle. Also, the left and right directions are synonymous with the vehicle width direction.

[0021] <First Embodiment> First, the first embodiment will be described. As shown in FIG. 1, the seal structure 20 according to the first embodiment is provided in the engine compartment 12 of the vehicle 10, for example, above the fender liner 14 and on the outer side in the vehicle width direction of the cowl side member 16, and is composed of a seal member 22.

[0022] The seal member 22 is formed to a predetermined thickness by an elastic body such as urethane foam, and in a front view seen from the front-rear direction, it seals (fills) the gap generated above the fender liner 14 and on the outer side in the vehicle width direction of the cowl side member 16, and is formed in a shape that substantially matches the gap.

[0023] As shown in FIG. 2, a plurality of groove portions 24 extending in the vehicle width direction are formed on the front wall and the rear wall of the seal member 22. In other words, a plurality of concave and convex shapes are formed on the front wall and the rear wall of the seal member 22 in a side view seen from the vehicle width direction. Thus, a configuration is provided in which the seal member 22 can be made lighter compared to the case where the groove portions 24 (concave and convex shapes) are not formed.

[0024] Furthermore, as shown in Figure 1, a sealing member 21 having the same function as the sealing member 22 is also provided above the sealing member 22. Preferably, the lower wall of the upper sealing member 21 and the upper wall of the lower sealing member 22 are configured to be able to fit together, for example, and the upper sealing member 21 is fixed to the fender extension panel (not shown) by, for example, a clip (not shown).

[0025] The sealing member 22 constituting the sealing structure 20 has a recess 26 formed as a notch to create a gap G through which cables 18 such as wire harnesses and washer hoses can pass. Specifically, a recess 26, roughly U-shaped in front view, is formed to a predetermined depth approximately in the vertical center on the inner side in the vehicle width direction of the sealing member 22. Cables 18 in the engine compartment 12 are routed through this roughly U-shaped gap G provided by this recess 26. Note that the cables 18 passing through the gap G are not limited to the one shown in the figure.

[0026] Furthermore, as shown in Figures 2 and 3, a resonator-type sound-dampening chamber 30 with sound-dampening function is integrally formed inside the sealing member 22. That is, this sound-dampening chamber 30 is integrally formed by molding the sealing member 22 with a mold (not shown), and its opening 32 is located approximately in the center in the vertical direction and approximately in the center in the thickness direction of the bottom surface 26A of the recess 26. In other words, the opening 32 of the sound-dampening chamber 30 opens toward the inside in the vehicle width direction.

[0027] The sound-dampening chamber 30 is formed in a hollow, approximately cylindrical shape and has a connecting section 34 that acts as a connecting pipe with the same inner diameter as the circular opening 32 and continues for a predetermined length, an enlarged diameter section 36 that gradually increases in inner diameter from the connecting section 34 and continues for a predetermined length, and a main body section 38 that continues for a predetermined length with the maximum inner diameter of the enlarged diameter section 36. In other words, the sound-dampening chamber 30 is formed perpendicular to the bottom surface 26A of the recess 26, and its axial direction is aligned with the vehicle width direction.

[0028] The dimensions of the sound-dampening chamber 30 (including the opening 32) are set appropriately according to the type of vehicle 10, etc. Here, if the resonant frequency is f, the speed of sound is c, the length of the connecting section 34 is L, the cross-sectional area of ​​the connecting section 34 is S, and the volume of the main body section 38 including the enlarged diameter section 36 is V, then the theoretical formula for the Helmholtz resonator is as follows.

[0029] f = c / (2 × π) × (S / (L × V)) 1 / 2

[0030] Therefore, in the mold used to mold the sealing member 22, by appropriately setting the length L of the communication portion 34, the cross-sectional area S of the communication portion 34, and the volume V of the main body portion 38 including the enlarged diameter portion 36, it becomes possible to reduce noise of a specific frequency appropriate to the type of vehicle 10 (which differs for each type of vehicle 10).

[0031] The operation of the seal structure 20 according to the first embodiment, which has the configuration described above, will now be explained.

[0032] As shown in Figure 1, the sealing member 22 constituting the sealing structure 20 according to the first embodiment is provided to seal the gap that occurs in the engine compartment 12 of the vehicle 10 when viewed from the front. Specifically, the sealing member 22 is provided on the upper part of the fender liner 14 and on the outer side in the vehicle width direction of the cowl side member 16 when viewed from the front.

[0033] Furthermore, the cable 18 inside the engine compartment 12 is routed through a gap G provided by the recess 26 of the sealing member 22. In other words, in order to route the cable 18, a roughly "U" shaped gap G is formed between the sealing member 22 and the outer end of the cowl side member 16 in the vehicle width direction when viewed from the front. Therefore, it is easy to pass the cable 18 through this gap G.

[0034] Here, a sound-absorbing chamber 30 is formed inside the sealing member 22, and its opening 32 is provided on the bottom surface 26A of the recess 26. Therefore, even though a gap G for the cable 18 is provided by the recess 26, at least a portion of the noise passing through that gap G (engine noise or motor noise, road noise and pattern noise from the front tires, etc.) enters the sound-absorbing chamber 30 through the opening 32 and is silenced. This reduces the noise transmitted from the engine compartment 12 to the passenger compartment, and more specifically, the noise that enters the cowl (not shown) from the top of the fender liner 14 and is transmitted to the passenger compartment.

[0035] Furthermore, the sound-dampening chamber 30 is formed perpendicular to the bottom surface 26A of the recess 26, with its opening 32 facing inward in the vehicle width direction, and its axial direction is aligned with the vehicle width direction. In the case of a sound-dampening chamber that is not formed perpendicular to the bottom surface 26A of the recess 26 (not shown), some sound waves (noise) are reflected in the curved portion, i.e., the connecting portion (connecting pipe) leading to the main body, making it impossible to efficiently guide the noise (sound waves) to the main body.

[0036] In contrast, the sound-absorbing chamber 30 according to the first embodiment is formed perpendicular to the bottom surface 26A of the recess 26. Therefore, compared to a sound-absorbing chamber that is not formed perpendicular to the bottom surface 26A of the recess 26 (not shown), at least a portion of the noise passing through the gap G provided by the recess 26 (noise of a specific frequency, especially noise traveling along the front-to-back direction) can be efficiently guided to the main body 38. Consequently, at least a portion of that noise can be effectively silenced.

[0037] Furthermore, since the sound-absorbing chamber 30 is formed integrally with the seal member 22 during the molding process, the seal member 22 can be manufactured more easily compared to a configuration (not shown) in which the sound-absorbing chamber is molded separately and then embedded in the seal member. In addition, by forming the sound-absorbing chamber 30, a portion of the seal member 22 is removed, resulting in a lighter seal member (not shown) and reduced manufacturing costs (material costs) compared to a seal member without a sound-absorbing chamber.

[0038] <Second Embodiment> Next, a second embodiment will be described. Note that parts equivalent to those in the first embodiment are denoted by the same reference numerals, and detailed descriptions (including common functions) will be omitted as appropriate.

[0039] As shown in Figure 4, the sealing member 22 in the second embodiment has multiple sound-absorbing chambers 30 (two additional chambers, for a total of three). More specifically, in addition to the sound-absorbing chambers 30, the sealing member 22 further includes a resonator-type sound-absorbing chamber 30U with an opening 32U provided on the upper side surface (top surface) 26U of the recess 26, and a resonator-type sound-absorbing chamber 30D with an opening 32D provided on the lower side surface (bottom surface) 26D of the recess 26.

[0040] The sound-dampening chamber 30U is formed in a hollow, substantially cylindrical shape and has a connecting section 34U that has the same inner diameter as the circular opening 32U and continues for a predetermined length, an enlarged diameter section 36U that gradually increases in inner diameter from the connecting section 34U and continues for a predetermined length, and a main body section 38U that has the nearly maximum inner diameter of the enlarged diameter section 36U and continues for a predetermined length. In other words, the sound-dampening chamber 30U is formed perpendicular to the side surface 26U of the recess 26 with the opening 32U facing downwards, and its axial direction is aligned with the vertical direction.

[0041] Similarly, the sound-dampening chamber 30D is formed in a hollow, roughly cylindrical shape and has a connecting section 34D that has the same inner diameter as the circular opening 32D and continues for a predetermined length, an enlarged diameter section 36D that gradually increases in inner diameter from the connecting section 34D and continues for a predetermined length, and a main body section 38D that has the nearly maximum inner diameter of the enlarged diameter section 36D and continues for a predetermined length. In other words, the sound-dampening chamber 30D is formed perpendicular to the side surface 26D of the recess 26 with the opening 32D facing upward, and its axial direction is aligned with the vertical direction.

[0042] Thus, when a sound-absorbing chamber 30 with an opening 32 provided on the bottom surface 26A of the recess 26, and sound-absorbing chambers 30U and 30D with openings 32U and 32D provided on the sides 26U and 26D of the recess 26, respectively, are formed inside the sealing member 22, even if a gap G for passing the cable 18 is provided by the recess 26, at least a portion of the noise passing through the gap G enters the sound-absorbing chambers 30, 30U, and 30D through the respective openings 32, 32U, and 32D and is silenced.

[0043] Therefore, noise transmitted from the engine compartment 12 to the passenger compartment can be effectively reduced. In particular, if the dimensions of each sound-dampening chamber 30, 30U, and 30D are appropriately set so that noise of different specific frequencies is reduced for each chamber, the noise transmitted from the engine compartment 12 to the passenger compartment (noise of multiple different specific frequencies) can be reduced more effectively.

[0044] Furthermore, each sound-dampening chamber 30, 30U, and 30D is formed perpendicular to the bottom surface 26A and sides 26U and 26D of the recess 26. If each sound-dampening chamber were not formed perpendicular to the bottom surface 26A and sides 26U and 26D of the recess 26, some sound waves (noise) would be reflected in the curved parts, i.e., the connecting parts (connecting pipes) leading to each main body, making it impossible to efficiently guide the noise (sound waves) to the main body.

[0045] In contrast, in the second embodiment, each sound-absorbing chamber 30, 30U, and 30D is formed perpendicular to the bottom surface 26A and side surfaces 26U and 26D of the recess 26. Therefore, compared to the case where each sound-absorbing chamber is not formed perpendicular to the bottom surface 26A and side surfaces 26U and 26D of the recess 26, at least a portion of the noise passing through the gap G provided by the recess 26 (which is noise of multiple different specific frequencies, and in particular noise that travels along the front-to-back direction) can be efficiently guided to each main body 38, 38U, and 38D. Thus, at least a portion of the noise can be effectively silenced.

[0046] <Third Embodiment> Next, a third embodiment will be described. Note that parts equivalent to those in the first embodiment will be denoted by the same reference numerals, and detailed descriptions (including common functions) will be omitted as appropriate.

[0047] As shown in Figure 5(A), in the third embodiment, the sealing member 22 has a sound-absorbing chamber 40 formed as a separate path with a predetermined length, which is roughly U-shaped in cross-sectional view. This sound-absorbing chamber 40 is of the sound wave interference type with a constant overall inner diameter, and has an opening 42 which is either the sound inlet or outlet, and an opening 44 which is either the sound inlet or outlet, provided at a predetermined distance in the thickness direction, approximately in the vertical center of the bottom surface 26A of the recess 26. In other words, this sound-absorbing chamber 40 is also formed perpendicular to the bottom surface 26A of the recess 26, with each opening 42, 44 facing inward in the vehicle width direction.

[0048] In such a sound-dampening chamber 40, as shown in Figure 5(B), for example, some of the noise passing through the gap G from the front to the rear enters the sound-dampening chamber 40 through the opening 42 and exits through the opening 44. Therefore, at least some of the noise that has passed through the gap G from the front to the rear is silenced by interference (cancellation of sound waves with phase differences) at the point where it merges with some of the noise that has exited through the opening 44 (sound pressure at a specific frequency is reduced).

[0049] In other words, even though a gap G for the cable 18 is provided by the recess 26, at least a portion of the noise passing through the gap G is silenced by the sound-dampening chamber 40, which creates a phase difference in the noise (sound waves). Therefore, noise (in the case of sound wave interference, noise of a specific frequency) transmitted from the engine compartment 12 to the passenger compartment can be effectively reduced.

[0050] Furthermore, since the sound-dampening chamber 40 is formed perpendicular to the bottom surface 26A of the recess 26, it can effectively dampen at least a portion of the noise passing through the gap G provided by the recess 26 (noise of a specific frequency, especially noise traveling along the front-to-back direction) compared to a case where the sound-dampening chamber 40 is not formed perpendicular to the bottom surface 26A of the recess 26.

[0051] <Fourth Embodiment> Next, a fourth embodiment will be described. Note that parts equivalent to those in the first embodiment are denoted by the same reference numerals, and detailed descriptions (including common functions) will be omitted as appropriate.

[0052] As shown in Figure 6(A), the sealing member 22 in the fourth embodiment has a hollow cylindrical sound-absorbing chamber 46 formed therein for a predetermined length. This sound-absorbing chamber 46 is of a side-branch type with a constant overall inner diameter, and the opening 48 is provided approximately in the center in the vertical direction and approximately in the center in the thickness direction of the bottom surface 26A of the recess 26. In other words, this sound-absorbing chamber 46 is also formed perpendicular to the bottom surface 26A of the recess 26, with its opening 48 facing inward in the vehicle width direction, and its axial direction is aligned with the vehicle width direction.

[0053] Therefore, even though a gap G for the cable 18 is provided by the recess 26, at least a portion of the noise passing through the gap G enters the sound-dampening chamber 46 through the opening 48 and is silenced. This makes it possible to reduce the noise (in the case of a side branch type, noise of a specific frequency) transmitted from the engine compartment 12 to the passenger compartment.

[0054] Furthermore, since the sound-dampening chamber 46 is formed perpendicular to the bottom surface 26A of the recess 26, it can effectively dampen at least a portion of the noise passing through the gap G provided by the recess 26 (noise of a specific frequency, especially noise traveling along the front-to-back direction) compared to a case where the sound-dampening chamber 46 is not formed perpendicular to the bottom surface 26A of the recess 26.

[0055] <Fifth Embodiment> Finally, the fifth embodiment will be described. Note that parts equivalent to those in the first embodiment are denoted by the same reference numerals, and detailed descriptions (including common functions) will be omitted as appropriate.

[0056] As shown in Figure 6(B), the sealing member 22 in the fifth embodiment has a hollow rectangular prism-shaped sound-absorbing chamber 50 formed therein, with the vertical direction being the longitudinal direction. This sound-absorbing chamber 50 is an extended type, formed to a predetermined depth (length) while being the same size as the rectangular opening 52 provided on the bottom surface 26A of the recess 26, with the vertical direction being the longitudinal direction. In other words, this sound-absorbing chamber 50 is also formed perpendicular to the bottom surface 26A of the recess 26, with its opening 52 facing inward in the vehicle width direction.

[0057] Therefore, even though a gap G for the cable 18 is provided by the recess 26, at least a portion of the noise passing through the gap G enters the sound-dampening chamber 50 through the opening 52 and is silenced. This makes it possible to reduce the noise transmitted from the engine compartment 12 to the passenger compartment (in the case of the extended type, noise of a wide range of frequencies).

[0058] Furthermore, since the sound-dampening chamber 50 is formed perpendicular to the bottom surface 26A of the recess 26, it can effectively dampen at least a portion of the noise passing through the gap G provided by the recess 26 (which is wide-frequency noise, especially noise traveling along the front-to-back direction) compared to a case where the sound-dampening chamber 50 is not formed perpendicular to the bottom surface 26A of the recess 26.

[0059] The seal structure 20 according to this embodiment has been described above based on the drawings. However, the seal structure 20 according to this embodiment is not limited to the illustrated form, and can be modified as appropriate without departing from the spirit of the present invention. For example, the shapes of the seal members 21 and 22 are not limited to the illustrated form, and can be formed to an appropriate shape in accordance with the shape of the gaps in each part formed in the engine compartment 12 when viewed from the front.

[0060] Furthermore, as shown in Figures 1 and 3, the gap for passing the cable may also be formed by an inverted "L" shaped notch 28 formed on the lower end of the outer side of the sealing member 22 in the vehicle width direction, and a sound-absorbing chamber (not shown) with an opening (not shown) provided at the bottom surface 28A of the notch 28 may be further formed inside the sealing member 22 so as to be perpendicular to the bottom surface 28A. Also, the shape of the notch (recess 26, notch 28) is not limited to the shape shown, and may be, for example, a roughly semicircular shape (not shown).

[0061] Furthermore, to allow water (rainwater, etc.) that enters each of the sound-dampening chambers 30, 40, and 46 to be discharged, the sealing member 22 may be provided with drainage holes (not shown) that communicate with the lower side of the inner circumferential wall of each of the sound-dampening chambers 30, 40, and 46, along the vertical direction. Also, to allow water that enters each of the sound-dampening chambers 30, 40, and 46 to be discharged, each of the sound-dampening chambers 30, 40, and 46 may be formed with a very slight downward inclination relative to the bottom surface 26A of the recess 26.
