Abstract

The invention provides a vehicle door which has drainage performance and improves sound insulation performance. A vehicle door (1) having an inner panel (21) constituting the inner wall of a vehicle compartment and a water leakage hole (22) penetrating the inner panel (21) is provided with a sound insulation cover (41), wherein the sound insulation cover (41) surrounds at least a part of the periphery of the water leakage hole (22) and is provided with a diversion wall (43) intersecting with the extension direction of the water leakage hole (22) towards the inside of the vehicle.

Description

Vehicle door

Technical Field

The present invention relates to a vehicle door having a water leakage hole for discharging water accumulated inside.

Background

Water caused by rain or the like enters the interior of the vehicle door along the door glass that is lifted up and down. The immersed water is a cause of freezing and corrosion, and therefore, it is desired to quickly discharge the water. Therefore, conventionally, a water leakage hole has been widely provided in a vehicle door.

For example, in patent document 1, a water leakage hole is provided in a lower portion of an inner panel constituting an inner surface of a vehicle door. The water that has passed through the water leakage hole and is discharged from the door interior into the vehicle interior passes through the groove portion (which is formed by the seal member provided between the side sill on the vehicle body side and the vehicle door) and is discharged to the outside of the vehicle.

Disclosure of Invention

However, in patent document 1, since the water leakage holes are not treated at all, there is a problem that noise transmitted to the interior of the door such as road noise and wind noise is radiated to the interior of the vehicle through the water leakage holes.

Accordingly, an object of the present invention is to provide a vehicle door having improved sound insulation while having drainage properties.

In order to achieve the above object, a vehicle door according to the present invention includes: an inner panel that constitutes an inner wall of a vehicle compartment; a water leakage hole penetrating the inner panel; and a sound insulation cover which surrounds at least a part of the periphery of the water leakage hole and is provided with a diversion wall which intersects with the extension direction of the water leakage hole towards the interior of the vehicle.

According to this configuration, the sound-insulating cover having the diversion wall that surrounds at least a part of the periphery of the water leakage hole and intersects with the extending direction of the water leakage hole toward the vehicle interior side is provided, so that the drainage passage in which the direction of the water flow along the penetrating direction of the water leakage hole is changed is formed on the vehicle interior side of the inner panel. Thus, the noise radiated through the water leakage hole is reflected by the soundproof cover, and therefore, the noise can be prevented from directly reaching the vehicle interior. Therefore, the vehicle door can have drainage properties and also improve sound insulation properties.

In the vehicle door, it is preferable that the soundproof cover includes a drain passage having: a drain passage inlet formed opposite to the water leakage hole; and a drain passage outlet formed below the water leakage hole and facing downward.

With this configuration, the noise radiated to the vehicle interior through the water leakage hole is reflected downward by the soundproof cover. This can prevent noise emitted through the water leakage hole from directly reaching the vehicle interior, and therefore can improve sound insulation.

In addition, in the vehicle door, it is preferable that an interior member is provided on an inner surface of the inner panel so as to overlap the soundproof cover from inside of the vehicle compartment.

According to this configuration, since the interior trim is provided on the inner surface of the inner panel so as to overlap the soundproof cover from the vehicle interior side, the noise radiated through the water leakage hole can be further suppressed from directly reaching the vehicle interior. This can further improve the sound insulation property while maintaining the water drainage property.

In addition, in the vehicle door, it is preferable that the door further includes: an outer panel that forms an exterior shape of the vehicle; an outer decoration member detachably provided on an outer surface of the outer panel via an outer assembly mechanism; an inspection hole penetrating the inner panel to enable access to the outer assembly mechanism; an inspection frame portion provided integrally with the soundproof cover and surrounding a periphery of the inspection hole; a maintenance hole that penetrates the interior trim so as to be communicable with the inspection hole, so that the exterior assembly mechanism can be accessed; and a cover which blocks the maintenance hole.

According to this configuration, when the exterior trim is detachably provided on the outer surface of the outer panel via the outer assembly mechanism, the following configuration is adopted: a maintenance hole is provided so that the outer assembly mechanism can be accessed and the inner garnish can be penetrated in communication with the inspection hole, and the maintenance hole is closed by a cover. This makes it possible to provide the exterior trim while having water-repellent and sound-insulating properties.

In addition, since the inspection frame surrounds the inspection hole, the diffusion of sound into the space between the inner panel and the interior material is suppressed, and the sound insulation performance can be improved.

In the vehicle door, it is preferable that the interior trim and the exterior trim are integrally coupled to each other below the outer panel, and the vehicle door includes a water drain hole formed as a through hole in the interior trim or the exterior trim located below the water drain hole.

According to such a configuration, the rigidity of the outer garnish and the inner garnish is improved by integrally connecting the outer garnish and the inner garnish, and therefore, the generation of noise due to vibration of the outer garnish and the inner garnish can be suppressed. In addition, by providing the drain hole in the interior trim at the same time, drainage is not impaired. According to the above configuration, the sound insulation performance can be further improved without impairing the drainage performance.

In the vehicle door, it is preferable that the soundproof cover includes a soundproof wall erected toward the inner panel so as to shield a gap between the water drain hole and the water drain hole.

According to such a configuration, the sound insulating wall of the sound insulating cover is erected toward the inner panel so as to shield the space between the water leakage hole and the water discharge hole, thereby forming a labyrinth structure between the water leakage hole and the water discharge hole. This prevents noise from entering the door interior linearly, and therefore improves sound insulation.

In the vehicle door, it is preferable that the soundproof cover is formed of a member separate from the interior member and is provided integrally with the interior member.

According to such a configuration, by forming the soundproof cover and the interior member from separate members, the soundproof cover can be formed into a more appropriate shape without impairing the aesthetic appearance of the interior member, as compared with a case where the soundproof cover and the interior member are formed from one member.

In the vehicle door, it is preferable that the soundproof cover is separated from the inner panel.

According to such a configuration, when the soundproof cover is fixed to both the interior trim and the interior panel, if the dimensional accuracy is low, the soundproof cover may shake due to vibration, which causes noise. Therefore, the molding accuracy has to be improved, which leads to an increase in manufacturing cost. However, by setting the shape so that the soundproof cover is separated from the inner panel, the generation of noise due to vibration can be suppressed without increasing the forming accuracy. Therefore, the sound insulation property can be improved while suppressing the manufacturing cost.

Effects of the invention

According to the present invention, it is possible to provide a vehicle door having drainage properties and improved sound insulation properties.

Detailed Description

An embodiment of the present invention is described in detail with reference to the accompanying drawings where appropriate. The same components are denoted by the same reference numerals, and redundant description thereof is omitted.

The vehicle door of the present embodiment constitutes a side door 1 that opens and closes an opening of a vehicle (not shown) in which an occupant rides.

As shown in fig. 1 to 5, the side door 1 is configured by integrally joining an outer panel 11 and an inner panel 21. A storage chamber AR1 is formed between the outer panel 11 and the inner panel 21, and a door glass (not shown) that can be lifted and lowered is stored in the storage chamber AR 1.

The outer panel 11 forms the exterior shape of the vehicle. The outer panel 11 is provided with an exterior member 12 detachably attached to a lower portion of an outer surface 11a thereof via an exterior assembly mechanism 13.

The exterior trim 12 is formed by injection molding a resin material to improve the decorativeness of the exterior panel 11.

The outer assembly mechanism 13 is constituted by two fixing mechanisms, a clamp fixing mechanism 31 and a screw fixing mechanism 32.

The clip fixing mechanisms 31 are set at a plurality of positions along the vehicle front-rear direction between the outer panel 11 and the exterior trim 12. As shown in fig. 4, the jig fixing mechanism 31 is composed of: a panel-side jig base 31a formed of a through hole opened in the outer panel 11; a garnish-side clip base 31b formed on a vehicle-interior-side surface 12a of the exterior garnish 12; and a jig 31 c. The clip 31c has one end inserted into the panel-side clip base 31a and the other end detachably engaged with the garnish-side clip base 31 b.

As shown in fig. 5, the screw fixing mechanism 32 is set at a portion between the outer panel 11 and the outer garnish 12, which is located at the central portion of the outer garnish 12. The screw fixing mechanism 32 is constituted by a panel-side screw base 32a provided on the outer panel 11, a garnish-side screw base 32b formed on the vehicle-interior side surface 12a of the outer garnish 12, and a screw 32 c. The exterior trim 12 is fixed to the exterior panel 11 by inserting the screws 32c into the panel-side screw base 32a and screwing the screws into the trim-side screw base 32 b.

The inner panel 21 constitutes an inner wall of the vehicle compartment. The inner panel 21 has three openings 22 at the front, center, and rear near the joint portion of the lower edge thereof. The inner panel 21 has an inspection hole (access hole)23 opened near the central water leakage hole (central water leakage hole 22).

A sound insulating cover 41 (see fig. 2) is disposed on the surface of the inner panel 21 on the vehicle interior side so as to surround the water leakage holes 22. The inner panel 21 is provided with an interior trim 51 on an inner surface 21a (a panel surface facing the vehicle interior side) of the inner panel 21 so as to overlap the soundproof cover 41 from the vehicle interior side and to be attachable and detachable via an interior assembly mechanism (not shown). Note that, as will be described later, the soundproof cover 41 is provided integrally with the interior member 51, but in fig. 2, for convenience of explanation, the interior member 51 is shown in a state where the soundproof cover 41 is left on the inner panel 21.

The water leakage hole 22 is a through hole penetrating the inner panel 21, and communicates the storage chamber AR1 with the vehicle interior side of the intermediate chamber AR2 described later. Then, water based on rain, snow, or the like that has entered the storage chamber AR1 along the door glass that has been raised and lowered is discharged from the storage chamber AR1 through the drain hole 22.

The inspection hole 23 is a through hole penetrating the inner panel 21. The inspection hole 23 is formed in a hole shape that enables attachment/detachment (contact) of the screw 32c of the screw fixing mechanism 32 by a tool (not shown) such as a driver.

The soundproof cover 41 is set to each of the water leakage holes 22. That is, the soundproof cover 41 includes a front cover 41F surrounding the periphery of the front water drain hole 22, a center cover 41M surrounding the periphery of the center water drain hole 22, and a rear cover 41R surrounding the periphery of the rear water drain hole 22 (see fig. 2).

As shown in fig. 6 to 13, the soundproof cover 41 includes: a sound insulating wall 42 that surrounds the periphery of the water leakage hole 22 at three positions, i.e., the upper position, the front position, and the rear position, and is erected from the vehicle interior toward the inner panel 21; and a direction changing wall 43 obliquely crossing the extending direction of the water leakage hole 22 toward the vehicle interior side. That is, the soundproof cover 41 is formed in a cross-sectional コ shape by the variable direction wall 43 and the soundproof wall 42 standing from the periphery of the variable direction wall 43. The groove portion on the inner side of the コ -shaped sound insulation cover 41 is defined as a drain passage 44, and the drain passage 44 changes the direction of water flow along the penetration direction of the drain holes 22.

As shown in fig. 4, in the drain passage 44, a drain passage inlet 44a serving as an inlet is formed to face the water leakage hole 22, and a drain passage outlet 44b serving as an outlet is formed to face downward below the water leakage hole 22. That is, the drain passage inlet 44a is formed by a portion that surrounds the drain hole 22 through the inner panel 21 side end edges of the front wall, the upper wall, and the rear wall of the sound insulating wall 42. The drain passage outlet 44b is located below the lower ends of the inner panel 21 and the outer panel 11, and is formed by a portion surrounded by the side end edges of the inner panel 21 of the front wall, the lower wall, and the rear wall of the sound insulating wall 42.

The soundproof cover 41 is formed of a member separate from the interior 51, and is provided integrally with the interior 51 by a joining means such as a double-sided tape or an adhesive.

The sound insulating wall 42 has a vertical dimension and a shape that shield a space between the water drain hole 22 and a water drain hole 52 described later. That is, the sound insulating wall 42 forms a labyrinth structure (see fig. 3) between the water leakage hole 22 and the water discharge hole 52. The sound insulating wall 42 is set to have a dimension such that the sound insulating wall 42 is spaced apart from the inner panel 21 by a predetermined distance. That is, the inner panel 21 side end edge of the sound insulating wall 42 is formed so as to draw the surface of the inner panel 21 at a predetermined interval.

The direction-changing wall 43 is sized and shaped so as to overlap the entire water leakage hole 22 when the water leakage hole 22 is viewed from the front. The direction changing wall 43 is opened at its front edge portion and rear edge portion with slits 45 extending in the vehicle vertical direction. The direction changing wall 43 is provided with a double-sided tape 61 between the pair of slits 45, and is attached to the vehicle exterior surface 51a of the interior trim 51 via the double-sided tape 61. Therefore, the redirecting wall 43 is formed following the shape of the vehicle exterior side surface 51a of the interior trim 51. The direction changing wall 43 of the front cover 41F and the center cover 41M is formed into a smooth curved surface similar to the shape of the vehicle interior surface 51b of the interior 51, and the direction changing wall 43 of the rear cover 41R is formed in an uneven manner.

The slit 45 is sized to allow insertion of a rib (not shown) provided to protrude from the vehicle exterior side surface 51a of the interior member 51. The slit 45 is defined by a rib insertion (not shown) at a position on the vehicle exterior side surface 51a of the interior member 51.

As shown in fig. 6 to 9, the center cover 41M integrally has a check frame 46.

The inspection frame 46 surrounds the periphery of the inspection hole 23, and a through hole 46a in the central portion of the inspection frame 46 communicates with the inspection hole 23. The inspection frame portion 46 has a rectangular frame shape, and has frame sides 47 surrounding the upper, lower, front, and rear sides of the inspection hole 23.

Each frame edge 47 has a substantially L-shaped cross section by the reinforcing wall 43a and the frame wall 47 a.

The reinforcing wall 43a is formed by extending the redirecting wall 43 toward the front of the vehicle.

The frame wall 47a is formed of an upright wall that is erected from the vehicle interior side toward the inner panel 21.

The upper, front, and rear frame walls 47a are disposed close to the inspection hole 23, and the lower frame wall 47b is set at a position farther from the inspection hole 23 than the remaining frame walls 47 a.

By separating the lower frame wall 47b from the inspection hole 23, the area of the reinforcing wall 43a can be enlarged, and the area in which the double-sided tape 61 is provided can be enlarged. Further, the inspection frame portion 46 can be more firmly provided to the interior trim 51 by enlarging the installation area of the double-sided tape 61. This can prevent the check frame 46 from rattling when the vehicle vibrates.

Further, the inspection frame portion 46 is formed integrally with the center cover 41M, so that the work of assembling the inspection frame portion 46 to the interior trim 51 is simplified.

The interior trim 51 is formed together with the exterior trim 12 by injection molding of a resin material, whereby the interior trim 51 and the exterior trim 12 are integrally connected below the outer panel 11. That is, the interior 51 and the exterior 12 are formed as one member via the hinge portion 55 having a thickness set to be foldable. An intermediate chamber AR2 (see fig. 4) is formed by a space between the outer garnish 12 and the outer panel 11 and a space between the inner garnish 51 and the inner panel 21.

Further, the interior member 51 has a drain hole 52 opened at a portion below the drain hole 22, and a maintenance hole 53 opened at a portion facing the inspection hole 23.

As shown in fig. 3 and 4, the drain hole 52 is a through hole penetrating the interior member 51, and communicates the intermediate chamber AR2 with the outside of the vehicle.

The drain hole 52 constitutes an engagement structure 71 set in a portion of the interior 51 offset in the vehicle longitudinal direction from a position vertically below the drain hole 22.

The engagement structure 71 is a structure for locking the interior member 51 to the exterior member 12, and is composed of a claw arm 72 and a claw support base 73.

The hook arm portion 72 is erected by punching and raising the bottom of the interior member 51, and has a hook 74 formed at the distal end. The portion of the interior 51 where the hook arm portion 72 is punched out is set as the drainage hole 52. The hook arm 72 is flexible, and is inserted into the engagement hole 75 of the hook support base 73 while being deformed, and the hook 74 engages with the engagement hole 75 with respect to the pull-out direction.

That is, the finger arm portion 72 is formed so as to cover the upper side of the drain hole 52. Therefore, the sound insulation effect similar to that of the sound insulation cover 41 for the water leakage hole 22 according to the present embodiment is obtained by the hook arm portion 72 facing the water drainage hole 52.

Further, by providing the engaging structure 71, even if the hinge portion 55 is broken, the separation of the exterior trim 12 and the interior trim 51 can be suppressed.

The water that has entered the intermediate chamber AR2 through the water leakage hole 22 is discharged to the outside of the vehicle through the water drainage hole 52. That is, when water such as rain or snow enters the storage chamber AR1 along the door glass that can be raised and lowered, the water is discharged from the storage chamber AR1 to the intermediate chamber AR2 through the water leakage hole 22. The water that has entered the intermediate chamber AR2 is discharged to the outside of the vehicle through the water discharge hole 52.

As shown in fig. 5, the maintenance hole 53 is a through hole penetrating the interior member 51, and is closed by a detachable cover 54. The maintenance hole 53 is set in position and hole shape so as to be accessible to the screw fixing mechanism 32 (outer assembly mechanism 13) and to communicate with the inspection hole 23. That is, the maintenance hole 53 is set to a hole shape in which the operation of attaching/detaching (making contact with) the screw 32c of the screw fixing mechanism 32 (the outer assembly mechanism 13) can be performed by a tool (not shown) such as a driver, similarly to the inspection hole 23.

The inner assembly mechanism (not shown) has the same configuration as the above-described jig fixing mechanism 31 (outer assembly mechanism 13), and therefore, description thereof is omitted.

Next, the operational effects of the vehicle door 1 of the present embodiment will be described.

The sound insulating cover 41 is provided, and the sound insulating cover 41 surrounds at least a part of the periphery of the water leakage hole 22 and is provided with a direction changing wall 43 obliquely crossing the extending direction of the water leakage hole 22 toward the vehicle interior side, so that a water discharge passage 44 for changing the direction of water flow along the penetrating direction of the water leakage hole 22 is formed on the vehicle interior side of the inner panel 21. Accordingly, the noise radiated through the water leakage hole 22 is reflected by the soundproof cover 41, and therefore, the noise can be suppressed from directly reaching the vehicle interior. Therefore, the vehicle door 1 can have drainage properties and improve sound insulation properties.

The noise radiated to the vehicle interior through the water leakage hole 22 is reflected downward by the soundproof cover 41. This can suppress noise radiated through the water leakage hole 22 from directly reaching the vehicle interior, and can improve the sound insulation.

The interior trim 51 is provided on the inner surface of the inner panel 21 so as to overlap the soundproof cover 41 from the vehicle interior side, and thereby can further suppress noise radiated through the water leakage hole 22 from directly reaching the vehicle interior. This can further improve the sound insulation property while maintaining the water drainage property.

When the exterior trim 12 is detachably provided on the outer surface of the outer panel 11 by the exterior assembly mechanism 13, the structure is as follows: a maintenance hole 53 is provided so that the outer assembly mechanism 13 can be accessed and the inner garnish 51 can be penetrated in communication with the inspection hole 23, and the maintenance hole 53 is closed by a cover 54. This allows the exterior trim 12 to be provided with water-repellent and sound-insulating properties.

Further, by surrounding the inspection hole 23 with the inspection frame portion 46, it is possible to suppress sound from diffusing into the space between the inner panel 21 and the interior 51, and to improve sound insulation.

By integrally connecting the outer garnish 12 and the inner garnish 51, the rigidity of the outer garnish 12 and the inner garnish 51 is improved. This can suppress the generation of noise due to the vibration of the exterior trim 12 and the interior trim 51. Further, by providing the drain hole 52 in the interior member 51, the drainage property is not impaired. According to the above configuration, the sound insulation performance can be further improved without impairing the drainage performance.

The sound insulating wall 42 of the sound insulating cover 41 is erected toward the inner panel 21 so as to shield the space between the water leakage hole 22 and the water drainage hole 52, thereby forming a labyrinth structure between the water leakage hole 22 and the water drainage hole 52. This prevents noise from entering the interior of the intermediate chamber AR2, and therefore improves sound insulation.

By forming the soundproof cover 41 and the interior member 51 separately from each other as separate members, the soundproof cover 41 can be formed into a more appropriate shape without impairing the aesthetic appearance of the interior member 51, as compared with a case where the soundproof cover 41 and the interior member 51 are formed as one member.

When the soundproof cover 41 is fixed to both the interior member 51 and the inner panel 21, if the dimensional accuracy is low, the soundproof cover 41 may shake due to vibration, which causes noise. Therefore, the molding accuracy has to be improved, which leads to an increase in manufacturing cost. However, by setting the shape so that the soundproof cover 41 is separated from the inner panel 21, the generation of noise due to vibration can be suppressed without increasing the forming accuracy. Therefore, the sound insulation property can be improved while suppressing the manufacturing cost.

Note that the soundproof cover 41 of the present embodiment has a cross-sectional shape of コ, and the drainage passage 44 is formed in a groove shape. For example, a bent pipe (not shown) obtained by bending a circular pipe may be used instead of the soundproof cover, and the same operational effects as those of the present embodiment can be obtained. Further, the soundproof cover 41 may be separated from the interior material 21 and the soundproof cover 41 may be provided on the inner panel 21, and the same operational effects as those of the present embodiment can be obtained.

The water flow may be changed in the upward direction to store water in the drain passage 44 in the soundproof cover 41, thereby blocking the water leakage hole 22. By plugging the water leakage holes 22, the sound insulation in rainy weather can be further improved.

The soundproof cover 41 of the present embodiment is fixed to the interior member 51, and the soundproof wall 42 is spaced apart from the inner panel 21 by a predetermined distance. For example, the soundproof cover 41 may be fixed to the inner panel 21 and spaced apart from the interior 51 by a predetermined distance, and the same operational effects as those of the present embodiment can be obtained.

In the case where the exterior trim 12 is provided without providing the interior trim 51, the soundproof cover 41 may be provided on the inner panel 21, and the cover 54 may be provided on the inspection frame portion 46 to close the inspection hole 23.

The drain hole 52 of the present embodiment is opened at a portion of the interior member 51 located below the drain hole 22, but is not limited to such a configuration. For example, the same operational effect can be obtained by providing a structure in which the outer garnish 12 is opened at a portion that is lower than the water leakage hole 22 and is not noticeable from the outside.

The direction changing wall 43 of the present embodiment is set to have a size and a shape so as to overlap the entire water leakage hole 22 when the water leakage hole 22 is viewed from the front, but is not limited to this configuration. For example, the shape of the direction changing wall 43 may be set so as to overlap with a part of the water leakage hole 22 when the water leakage hole 22 is viewed from the front.
