Description

The present invention relates to door hole caps and sealing members.

2. Description of the Related Art Conventionally, a door hole cap has been used to prevent rainwater or the like from entering the inside of a vehicle through a door hole formed in a door inner panel of an automobile door. In general, a sponge material or the like is attached to the periphery of the door hole cap to prevent rainwater or the like from entering. However, the work of attaching the sponge material or the like to the door hole cap is time-consuming and requires skill for the work, so the number of man-hours for attaching the sealing member to the door hole cap increases, resulting in an increase in manufacturing cost. Therefore, there is a demand for a door hole cap that can reduce manufacturing costs while maintaining waterproofness.

For example, Patent Document 1 discloses a foamed sealing material comprising a resin panel main body having grooves and a foam sealing material formed by foaming and hardening a liquid foaming resin raw material in the grooves to bulge out on the surface of the panel body. A resin panel with a sealing material is disclosed.

JP 2009-166421 A

However, in the resin panel with foam sealing material disclosed in Patent Document 1, the liquid foam resin raw material is injected into the grooves and then foamed and cured. The work of injecting the liquid foamed resin raw material into the grooves may cause variations in the amount of injection depending on the operator, and may reduce the waterproof performance of the resin panel with the foamed sealing material. Furthermore, since it takes time to foam and harden the liquid foamed resin raw material, the working time is increased and the production cost is increased. Furthermore, once the foam sealing material is formed on the resin panel body, the foam sealing material alone cannot be easily removed. Therefore, even if a problem occurs only in the foam sealing material portion after forming the foam sealing material, it is necessary to replace the entire resin panel body, resulting in an increase in manufacturing cost.

One aspect of the present invention has been made in view of the above problems, and an object thereof is to provide a door hole cap or the like capable of reducing manufacturing costs while maintaining the waterproofness of the door hole cap.

In order to solve the above problems, a door hole cap according to one aspect of the present invention is a door hole cap to be attached to a door hole formed in a door inner panel of an automobile, the door hole cap having a groove recessed toward the inside of the vehicle. and a seal member attached to the groove, wherein the groove extends along the entire circumference of the first peripheral edge portion that is the peripheral edge portion of the cap member. The sealing member includes a main body portion inserted into the groove, and a body portion extending from the outer end portion of the main body portion toward the outer side of the vehicle so as to be attached to the inner surface of the door inner panel. and a groove contact portion that extends toward the inner surface of at least one side of the groove from the inner side of the outer end portion of the body portion and contacts the inner surface.

According to the above configuration, the attachment of the seal member to the cap member is completed by simply inserting the seal member into the groove of the cap member. Therefore, there is no need to perform operations such as positioning and bonding that are required when a sponge material or the like is attached to the door hole cap, and manufacturing variations due to work proficiency are less likely to occur. Furthermore, if a problem occurs only in the sealing member after attaching the sealing member to the cap member, only the sealing member can be easily replaced. Therefore, the manufacturing cost of the door hole cap can be reduced.

Further, according to the above configuration, the first seal portion attached to the first peripheral edge portion of the door hole cap is in contact with the door inner panel. That is, the manufacturing cost can be reduced while maintaining the waterproofness of the door hole cap.

In the door hole cap according to one aspect of the present invention, the sealing member extends from the vehicle-exterior end portion of the main body portion toward second peripheral edge portions, which are peripheral edge portions on both sides of the groove. A lip portion may be provided that abuts on each of the second peripheral edge portions.

According to the above configuration, the groove is covered by the lip portion when the lip portion abuts the second peripheral edge portions, which are the peripheral edge portions on both sides of the groove, from the outside of the vehicle. Thereby, the lip portion can reduce intrusion of rainwater or the like into the groove. Therefore, compared with the case where the sealing member does not have the lip portion, the water stopping performance of the sealing member can be improved.

Further, according to the above configuration, the lip portion is in contact with the second peripheral edge portions on both sides of the groove, so that the lip portion supports the sealing member attached to the groove from both sides. Therefore, the mounting posture of the seal member attached to the groove is more stable than when the seal member does not have a lip portion.

The door hole cap according to one aspect of the present invention extends from the main body side of the tip of the lip portion on the end side of the door hole cap toward the inner surface of the door inner panel, You may provide the 2nd sealing part which contact|abuts on the surface inside the said vehicle.

According to the above configuration, the seal member has the second seal portion that abuts on the door inner panel, so that both the first seal portion and the second seal portion prevent rainwater and the like from passing through the seal member and entering the vehicle. It can effectively prevent intrusion. Therefore, compared with the case where the seal member does not have the second seal portion, the water stoppage of the door hole cap can be improved.

Also, the second seal portion extends from the lip portion. Therefore, when the second seal portion comes into contact with the inner door panel, a force applied from the inner door panel toward the interior of the vehicle acts on the lip portion through the second seal portion. Therefore, since the lip portion is strongly pressed against the second peripheral portion from the outside of the vehicle, it is possible to effectively prevent rainwater or the like from entering the groove.

In the door hole cap according to one aspect of the present invention, the cap member has one end of the groove opposed to the other end, and the one end and the other end are Parallel portions formed in parallel in a surface direction of the cap member where the groove is formed are formed as part of the groove, and a portion of the parallel portion includes the one end portion, The width of the groove may be formed wider than the other portion by connecting the other end portion.

According to the above configuration, parallel portions are formed in the grooves formed in the cap member. If the parallel portion is not formed in the groove, the ends of the seal member cannot contact each other in a watertight manner due to manufacturing variations, etc., and a portion where the sealing by the seal member is insufficient occurs on the first peripheral edge portion. Sometimes. On the other hand, in the cap member, since both end portions of the seal member are partially attached in parallel to the parallel portions, occurrence of insufficiently sealed portions can be prevented.

Moreover, while the grooves are connected in a part of the parallel portion, the grooves are not connected in the other portion of the parallel portion, and two grooves are formed in parallel. With such a configuration, even if a minute passage is formed by the two sealing members and the door inner panel in contact with each other in a portion of the parallel portion where the ends of the groove are connected, the groove is caused by capillary action. Possibility of infiltration of rainwater or the like into the interior can be reduced. Therefore, compared to the case where the grooves are connected over the entire parallel portion, the water stoppage of the door hole cap can be improved.

Furthermore, it is preferable to install the sealing member on the side of the door hole first in the parallel portion where the grooves are connected to each other. By doing so, the second seal portion is folded between the first seal portion and the groove contact portion, and the first seal portions of the two seal members that contact each other in the parallel portion where the grooves are connected also contact each other. It can be brought into contact, and the water stoppage can be further improved.

In the door hole cap according to one aspect of the present invention, the first seal portion may be softer than the body portion. According to the above configuration, when the first seal portion is pressed against the door inner panel, the first seal portion is flexed to facilitate close contact with the door inner panel, and the main body portion is less likely to flex than the first seal portion. Therefore, the main body is difficult to deform. Therefore, the seal member can easily maintain a state in which it is stably attached to the groove, and can exhibit high waterproof performance.

A seal member according to an aspect of the present invention is a door hole cap that is attached to a door hole formed in a door inner panel of an automobile. A seal member that is attached to a groove that is formed along the entire circumference and is recessed toward the vehicle interior, comprising: a main body that is inserted into the groove; a first seal portion extending toward the inner side of the door and contacting the surface of the inner door panel on the inner side of the vehicle; , and a groove contact portion that abuts on the inner surface.

<Outline of door hole cap 1 and installation example>
An outline of a door hole cap 1 according to an embodiment of the present invention and an installation example will be described with reference to FIG. In the example of FIG. 1, the upper side of the paper is the upper side of the vehicle, the lower side is the lower side of the vehicle, the right side is the front side of the vehicle (front side), the left side is the rear side of the vehicle (rear side), and the front side is the inside of the vehicle (inside the car). , and the back side corresponds to the outside of the vehicle (the outside of the vehicle). FIG. 1 is a view of the front door D viewed from the inside of the vehicle. However, this does not limit the direction in which the door hole cap 1 is attached to the automobile, and the door hole cap 1 may be attached in any direction to the automobile.

The front door D is an example of an automobile door, and is attached to a front door opening (not shown) of the automobile so that it can be opened and closed. The front door D includes a door outer panel (not shown) and a door inner panel D1, and a door hole D2 is formed in the door inner panel D1. The door hole D2 is an opening for a worker to insert his hands or tools to repair various parts arranged inside the front door D, for example.

The cap member 10 is formed with a groove 11 recessed toward the inside of the vehicle, and is attached to the door inner panel D1 so as to cover the door hole D2 from the inside of the vehicle. A seal member 20 is attached to the groove 11, and the seal member 20 is in contact with the inner surface of the door inner panel D1, thereby preventing rainwater from entering the vehicle through the door hole D2.

It should be noted that the mounting manner of the door hole cap 1 described above is merely an example. For example, the door of the automobile to which the door hole cap 1 is attached is not limited to the front door D shown in the example of FIG. The door hole cap 1 may thus be attached to, for example, a rear door or a sliding door (not shown). Moreover, the vehicle to which the door hole cap 1 is attached can be any type of vehicle, including sedans, hardtops, and convertibles.

<Structure of door hole cap 1>
The structure of the door hole cap 1 will be described with reference to FIG. 2 is a cross-sectional view of the door hole cap 1 attached to the door inner panel D1 shown in FIG. 1, taken along the line AA. Therefore, in the example of FIG. 2, the upper side of the paper is the upper side of the vehicle, the lower side is the lower side of the vehicle, the right side is the outer side of the vehicle (outside of the car), the left side is the inner side of the car (inside the car), and the front side is the front side of the vehicle (front side). , and the far side corresponds to the rear side of the vehicle (rear side).

As shown in FIG. 2, the door hole cap 1 has a structure in which a seal member 20 is inserted into a groove 11 formed in a first peripheral edge portion 12 that is the peripheral edge portion of the cap member 10 . The groove 11 is formed over the entire circumference of the first peripheral portion 12 . By attaching the door hole cap 1 to the door inner panel D1, the door hole cap 1 covers the door hole D2 from the inside of the vehicle, and the sealing member 20 faces the first peripheral edge part 12 of the door inner panel D1 on the inside surface of the door. abut.

The cap member 10 has a shape similar to that of the door hole D2 when viewed from the side of the vehicle, and is slightly larger than the door hole D2. As shown in FIGS. 1 and 2, since the sealing member 20 is attached to the first peripheral portion 12, the sealing member 20 has a structure surrounding the door hole D2.

Examples of the material of the cap member 10 include vulcanized rubber, thermoplastic elastomer, thermoplastic resin, metal, and the like. Examples of vulcanized rubbers include EPDM (ethylene-propylene-diene monomer), IR (isoprene rubber), CR (chloroprene rubber), styrene-butadiene rubber (SBR) or acrylonitrile-butadiene rubber (NBR). . Examples of thermoplastic elastomers include olefinic (TPO) or styrenic (TPS). Examples of thermoplastic molding resins include PE (polyethylene), PP (polypropylene), PVA (polyvinyl alcohol), PVC (polyvinyl chloride), PS (polystyrene), ABS (acrylonitrile-butadiene-styrene) and EVA (ethylene vinyl acetate). Examples of composites include collections of fibers such as fiberglass blends. Examples of metals include aluminum and iron.

<Structure of Sealing Member 20>
The structure of the seal member 20 will be described with reference to FIGS. 2 and 3. FIG. 3 is an enlarged sectional view of the sealing member 20. As shown in FIG. In the example of FIG. 3, the upper side corresponds to the outside of the vehicle (outside of the automobile), and the lower side corresponds to the inside of the vehicle (inside the automobile). As shown in FIG. 3, the sealing member 20 in this embodiment includes a body portion 21, a first sealing portion 22, a groove contact portion 23, a lip portion 24, and a second sealing portion 25. .

The body portion 21 is a portion that is inserted into the groove 11 . The main body portion 21 is formed so that the length from the outside of the vehicle to the inside of the vehicle is greater than or equal to the depth of the groove 11 when inserted into the groove 11 . The first seal portion 22 extends from the vehicle-exterior end portion of the body portion 21 toward the vehicle exterior side, and the first seal portion 22 abuts the vehicle-interior surface of the door inner panel D1. A lip-shaped groove contact portion 23 extends toward the inner surface of at least one side of the groove 11 from the inner side of the body portion 21 toward the inner surface of the groove 11 , and the groove contact portion 23 contacts the inner surface of the groove 11 .

In the present embodiment, as shown in FIG. 2, the groove abutting portions 23 extend toward the inner surfaces of both sides of the groove 11 from a plurality of locations, but the present invention is not limited to this. The groove contact portion 23 may be provided so as to extend toward at least one inner surface of the groove 11 . The seal member 20 can be firmly attached to the groove 11 by the contact of the groove contact portion 23 with the inner surface of the groove 11 .

Further, the groove contact portion 23 extends toward the inner surface of the groove 11 while being inclined toward the outside of the vehicle. Therefore, when the seal member 20 is inserted into the groove 11, the groove abutting portion 23 is likely to be elastically deformed so as to bend toward the outside of the vehicle. Therefore, the groove contact portion 23 is less likely to interfere with the insertion of the seal member 20 into the groove 11 . On the other hand, the groove abutting portion 23 is less likely to bend toward the inside of the vehicle. Therefore, the sealing member 20 is difficult to get out of the groove 11 . Thus, the groove abutting portion 23 can prevent the seal member 20 from unintentionally slipping out of the groove 11 .

Further, as shown in FIG. 2, even when the groove abutting portions 23 extend toward the inner surface of the groove 11 from a plurality of portions of the main body portion 21, the state in which the seal member 20 can be easily inserted into the groove 11 is maintained. However, the seal member 20 can have a shape that makes it more difficult for the seal member 20 to slip out of the groove 11 .

Since the seal member 20 includes the body portion 21, the first seal portion 22, and the groove contact portion 23, the cap member 10 can be easily attached to the cap member 10 by simply inserting the seal member 20 into the groove 11 of the cap member 10. Installation of the seal member 20 is completed. When attaching a sponge material or the like as a sealing member to a conventional door hole cap, it was necessary to perform operations such as positioning and adhesion. However, the present invention eliminates the need for such work, so that the manufacturing cost of the door hole cap 1 can be reduced.

Furthermore, the contact of the first seal portion 22 with the door inner panel D1 prevents rainwater or the like from entering the vehicle from outside through the door hole D2. The seal member 20 has a structure surrounding the door hole D2, and the first seal portion 22 is in contact with the door inner panel D1 on the periphery of the door hole D2. Therefore, the door hole cap 1 of the present invention can reduce the manufacturing cost while maintaining the waterproof property.

As shown in FIG. 2, the seal member 20 may have a lip portion 24 . The lip portions 24 extend from the vehicle-exterior end portion of the main body portion 21 toward the second peripheral edge portions 13, which are peripheral edge portions on both sides of the groove 11, and respectively contact the second peripheral edge portions 13 from the vehicle exterior side. The groove 11 is covered with the lip portion 24 by the lip portion 24 coming into contact with the second peripheral edge portions 13 on both sides of the groove from the outside of the vehicle. As a result, the lip portion 24 can prevent rainwater or the like from entering the groove 11 , thereby reducing rainwater or the like from entering the interior of the vehicle through the groove 11 . Therefore, according to the sealing member 20 having the lip portion 24 , the waterproofness of the door hole cap 1 can be improved as compared with the case where the sealing member 20 does not have the lip portion 24 .

In addition, since the lip portion 24 is in contact with the second peripheral edge portions 13 on both sides of the groove 11, the lip portion 24 supports the seal member 20 attached to the groove 11 from two directions. Therefore, according to the seal member 20 having the lip portion 24, the mounting attitude of the seal member 20 attached to the groove 11 can be stabilized compared to the case where the seal member 20 does not include the lip portion 24.

Furthermore, as shown in FIG. 2, the seal member 20 may have a second seal portion 25 . The second seal portion 25 extends from the lip portion 24 on the end portion side of the door hole cap 1 in the seal member 20 . More specifically, the second seal portion 25 extends from the body portion 21 side of the tip of the lip portion 24 on the end portion side toward the inner side surface of the door inner panel D1. Abut on the surface.

Since the seal member 20 includes the second seal portion 25 that contacts the door inner panel D1, both the first seal portion 22 and the second seal portion 25 prevent rainwater and the like from passing through the seal member 20 and entering the vehicle. It can effectively prevent intrusion. Therefore, according to the seal member 20 having the second seal portion 25 , the waterproofness of the door hole cap 1 can be improved as compared with the case where the seal member 20 does not include the second seal portion 25 .

Also, the second seal portion 25 extends from the lip portion 24 . Therefore, when the second seal portion 25 comes into contact with the door inner panel D1, a force applied from the door inner panel D1 toward the interior of the vehicle acts on the lip portion 24 through the second seal portion 25. As shown in FIG. Therefore, since the lip portion 24 is strongly pressed against the second peripheral portion 13 from the outside of the vehicle, it is possible to effectively prevent rainwater and the like from entering through the groove 11 .

Each part constituting the seal member 20 may be mainly made of vulcanized rubber, thermoplastic elastomer, thermoplastic resin, or the like. Examples of the vulcanized rubber material include EPDM, IR (isoprene rubber), CR (chloroprene rubber), styrene-butadiene rubber (SBR), acrylonitrile-butadiene rubber (NBR), and the like. As a material for the thermoplastic elastomer, for example, an olefin-based (TPO) or a styrene-based (TPS) can be used. Examples of thermoplastic resin materials that can be used include polyethylene (PE), polypropylene (PP), ethylene-vinyl acetate copolymer (EVA), and soft polyvinyl chloride. The material may be solid, foamed and spongy, or partly foamed and spongy and partly solid.

The first seal portion 22 may be formed softer than the body portion 21 . The term "soft" as used herein includes not only a mode in which the material itself is soft, but also a mode in which the material is easily deformed, such as a hollow shape. If the first seal portion 22 is softer than the main body portion 21, the first seal portion 22 is likely to bend when the first seal portion 22 is pressed against the door inner panel D1. The inner panel D1 is easily brought into close contact with the inner panel D1. Further, since the body portion 21 is less likely to bend than the first seal portion 22 , the body portion 21 is less likely to be deformed, so that the seal member 20 can easily maintain a state of being stably attached to the groove 11 . Therefore, the door hole cap 1 can stably exhibit high water stopping performance.

The first seal portion 22 may be mainly made of the same material as the seal member 20. In that case, the main body portion 21 is made solid and the first seal portion 22 is made like a foamed sponge. preferably. For example, it is particularly preferable that the first sealing portion 22 is made of a highly foamed EPDM material.

Seal member 20 may be manufactured by extrusion. By manufacturing the seal member 20 by extrusion molding, for example, when manufacturing the first seal portion 22 and the main body portion 21 with different materials, it is possible to manufacture easily and inexpensively compared to other manufacturing methods such as molding. is. However, the present invention is not limited to this, and the sealing member 20 may be manufactured by a conventionally known manufacturing method.

<Structure of Groove 11>
The structure of the groove 11 of the cap member 10 will be described with reference to FIGS. 1 and 4. FIG. Reference numeral 401 in FIG. 4 indicates a cross-sectional view taken along the line BB of the door hole cap 1 attached to the door inner panel D1 shown in FIG. Reference numeral 402 in FIG. 4 indicates a cross-sectional view of the door hole cap 1 attached to the door inner panel D1 shown in FIG. 1, taken along line CC. Reference numeral 403 in FIG. 4 indicates a cross-sectional view taken along the line DD of the door hole cap 1 attached to the door inner panel D1 shown in FIG. In the example of FIG. 4, the upper side of the paper is the inside of the car (inside the car), the lower side is the outside of the car (outside of the car), the right side is the front side of the car (front side), the left side is the rear side of the car (rear side), and the front side is The lower side of the vehicle and the inner side correspond to the upper side of the vehicle.

In this embodiment, as shown in FIG. Parallel portions 16 formed in parallel in the surface direction in which the grooves 11 are formed are formed as part of the grooves 11 , and a wide portion 17 that is part of the parallel portions 16 is formed on one end 14 . , and the other end 15 are connected to form the width of the groove 11 wider than the other portions. A specific description will be given below.

Reference numeral 401 in FIG. 4 is a cross-sectional view showing a state in which the sealing member 20 is inserted into the region 11a of the groove 11 other than the parallel portion 16. As shown in FIG. A region 11a in the groove 11 is capable of inserting one row of the sealing member 20, and a groove having a width suitable for inserting one row of the sealing member 20 is formed. Reference numeral 402 in FIG. 4 is a cross-sectional view of the groove 11 with the seal member 20 inserted into the region 11b of the wide portion 17. As shown in FIG. A region 11b in the groove 11 allows two rows of the seal members 20 to be inserted, and grooves having a width suitable for inserting the seal members 20 in two rows are formed. Further, reference numeral 403 in FIG. 4 is a cross-sectional view when the seal members 20 are inserted into the regions 11c of both end portions of the parallel portion 16 in the groove 11. As shown in FIG. A region 11c in the groove 11 allows one line of the sealing member 20 to be inserted, and grooves having a width suitable for inserting one line of the sealing member 20 are formed in parallel.

When the above-described parallel portion 16 is formed as part of the groove 11 in the cap member 10 , the seal member 20 can be reliably attached over the entire circumference of the first peripheral edge portion 12 . When the parallel portion 16 is not formed in the cap member 10, the groove 11 formed over the entire circumference of the first peripheral edge portion 12 is limited to only the portion that has the width of the region 11a indicated by reference numeral 401 in FIG. is. Therefore, when the seal member 20 is inserted into the groove 11, the length of the seal member 20 is shortened due to manufacturing variations, and the ends of the seal member 20 cannot abut each other, resulting in a decrease in watertightness. Therefore, there may be a portion where the sealing by the sealing member 20 is insufficient on the first peripheral portion 12 .

On the other hand, when the parallel portion 16 is formed in the cap member 10, part of the groove 11 has the width of the region 11b indicated by reference numeral 402 in FIG. Also, the grooves 11 can be formed in parallel in the cap member 10 as in the region 11c indicated by reference numeral 403 in FIG. Therefore, even if the seal member 20 has manufacturing variations or the like, since both ends of the seal member 20 are partially parallel and attached to the parallel portion 16, sealing is insufficient on the first peripheral edge portion 12. It is possible to prevent the occurrence of such parts.

In the present embodiment, the wide portion 17 has a region 11b of the groove 11 with a wide width, while the parallel portion 16 has a region 11c in which two grooves 11 are arranged side by side at both ends. Here, two rows of seal members 20 are inserted into one groove 11 in the wide portion 17, and a very small tubular passage S surrounded by the seal members 20 and the door inner panel D1 is formed along the groove 11. can be formed

For example, if the end (one end 14 in this embodiment) of the groove 11 on the vehicle lower side is the wide portion 17, the passage S formed at the one end 14 is likely to be exposed to rainwater or the like. If rainwater or the like splashes on the passage S, the passage S may absorb the rainwater or the like due to capillary action, and the rainwater or the like may enter the interior of the vehicle. On the other hand, when the region 11c is formed on the vehicle lower side of the parallel portion 16, the passage S formed at one end portion 14 is located on the vehicle upper side than the lower end of the sealing member 20 on the side of the door hole D2 in the parallel portion 16. Located in Therefore, since rainwater or the like is less likely to splash on the passage S, the possibility of rainwater or the like entering the groove 11 due to capillary action can be reduced. Therefore, compared to the case where the grooves 11 are connected over the entire parallel portion 16 to form the wide portion 17, the water stoppage of the door hole cap 1 can be improved.

However, the present invention is not limited to the structure of the groove 11 described above, and the groove 11 may be formed over the entire circumference of the first peripheral portion 12 .

<Drainage structure>
The drainage structure will be described with reference to FIG. 5 is a cross-sectional view of the door hole cap 1 attached to the door inner panel D1 shown in FIG. 1, taken along line EE. Therefore, in the example of FIG. 5, the upper side of the paper is the upper side of the vehicle, the lower side is the lower side of the vehicle, the right side is the outer side of the vehicle (outside of the car), the left side is the inner side of the car (inside of the car), the near side is the front side (front side), The far side corresponds to the rear side (rear side).

In this embodiment, the door hole cap 1 may have a drainage structure for draining water from between the first seal portion 22 and the second seal portion 25, as shown in FIG. Specifically, the door inner panel D1 below the door hole D2 may have a drain hole D3. According to the drain hole D3, even if rainwater or the like that reaches the first seal portion 22 from the door hole D2 enters between the first seal portion 22 and the second seal portion 25, the infiltrated rainwater or the like can be removed. It moves to the lower part of the door inner panel D1 along with gravity and is drained from the drain hole D3. Therefore, the drain hole D3 can form a drain structure in combination with the shape in which the first seal portion 22 and the second seal portion 25 are separated from each other, so that the water stopping performance of the door hole cap 1 can be improved.

[Modification]
(Modified example of seal member 20)
A plurality of modifications are conceivable for the door hole cap 1 and the sealing member 20 according to the present embodiment. Modifications of the door hole cap 1 and the sealing member 20 according to the present embodiment will be described below with reference to FIGS. 6 and 7. FIG. Reference numeral 601 in FIG. 6 is a cross-sectional view of the seal member 201 according to the modified example of the present invention. Reference numeral 701 in FIG. 7 is a cross-sectional view of the seal member 202 according to the modified example of the present invention. Reference numeral 602 in FIG. 6 is a cross-sectional view of the door hole cap 2 according to the modified example of the present invention. Reference numeral 702 in FIG. 7 is a cross-sectional view of the door hole cap 3 according to the modified example of the present invention.

In the example of reference numeral 601 in FIG. 6 and reference numeral 701 in FIG. 7, the upper side corresponds to the outside of the vehicle (outside of the automobile) and the lower side corresponds to the inside of the vehicle (inside the automobile). In addition, in the example of reference numeral 602 in FIG. 6 and reference numeral 702 in FIG. 7, the upper side is the inside of the vehicle (inside the automobile), the lower side is the outside of the vehicle (outside the automobile), the right side is the front side of the vehicle (front side), and the left side is the left side. corresponds to the vehicle rear side (rear side), the near side corresponds to the vehicle bottom side, and the far side corresponds to the vehicle top side.

The seal member 201 differs from the seal member 20 in the shape of the first seal portion 221, as indicated by reference numeral 601 in FIG. As indicated by reference numeral 602 in FIG. 6, by increasing the cross section of the first seal portion 221 compared to the first seal portion 22 of the seal member 20, the contact area between the first seal portion 221 and the door inner panel D1 is increased. is increasing. Such a configuration makes it difficult for rainwater or the like to enter the inside of the vehicle through the first seal portion 221, so that the water blocking performance of the door hole cap 2 can be improved. Furthermore, as indicated by reference numeral 602 in FIG. 6, when two rows of seal members 201 are inserted into the groove 11 in the wide portion 17, a structure in which a gap is less likely to be formed between the seal members 201 can be provided. The water stoppage of the door hole cap 2 can be improved.

Next, the sealing member 202 differs from the sealing member 20 in the shape of the body portion 211, as indicated by reference numeral 701 in FIG. By making the length of the main body portion 211 from the vehicle outer side to the vehicle inner side shorter than that of the main body portion 21 of the sealing member 20, the material required for manufacturing the sealing member 202 is reduced. can reduce the manufacturing cost of Furthermore, as indicated by reference numeral 702 in FIG. 7, since the cross section of the body portion 211 of the seal member 202 is short, the depth of the groove 11 of the cap member 101 can also be shortened. Therefore, less material is required to manufacture the cap member 101, and the manufacturing cost of the door hole cap 3 can be reduced. In addition, it becomes easier to insert the seal member 202 deep into the groove 11 .

(Modified example of groove 11)
Modifications of the groove 11 in the door hole cap 1 according to the present embodiment will be described below with reference to FIGS. 8 and 9. FIG. Reference numeral 801 in FIG. 8 is a cross-sectional view of a door hole cap 4 according to a modified example of the present invention taken along line BB in FIG. Reference numeral 802 in FIG. 8 is a cross-sectional view of the door hole cap 5 according to one modification of the present invention, taken along line BB in FIG.

As indicated by reference numeral 801 in FIG. 8, the door hole cap 4 differs from the door hole cap 1 in that it includes a cap member 102 having a groove 11c in which a through hole H1 is formed. The through hole H1 is formed by cutting off approximately half of the bottom side in the depth direction of the groove 11c. When the seal member 20 is inserted into such a groove 11c, at least part of the groove contact portion 23 is inserted into the through hole H1. The groove abutting portion 23 inserted into the through hole H1 is retained by the peripheral wall of the through hole H1 even if the seal member 20 is about to slip out. As described above, it is preferable that the door hole cap 4 has a through hole H1 formed in at least a portion of the groove 11c, into which at least a portion of the groove contact portion 23 is inserted.

The groove 11c may be formed in a tapered shape that narrows toward the bottom side so that it can be easily removed from the mold during manufacturing. In this case, the sealing member 20 is likely to slip out of the groove 11c as well as the mold. However, the groove 11c is provided with the through hole H1, and the seal member 20 can be prevented from slipping out of the groove 11c by engaging the groove contact portion 23 with the peripheral wall of the through hole H1.

As shown in FIG. 9, it is preferable that the groove 11c of the door hole cap 4 is provided with a plurality of fixing areas 18. As shown in FIG. The fixed region 18 is a region configured so that the seal member 20 can be easily fixed to the groove 11c, and is a region in the door hole cap 4 where the through hole H1 is formed. It is preferable that the fixed area 18 is set at the corner portion formed by bending the groove 11c in addition to the straight portion where the groove 11c is formed in a straight line on the peripheral edge of the door hole cap 4 . At such corners, it is difficult for the seal member 20 to stabilize its posture in the groove 11c.

As in the door hole cap 5 indicated by reference numeral 802 in FIG. 8, the fixed region 18 is formed only in a narrow portion with which one of the groove contact portions 23 abuts when the seal member 20 is fully inserted. through hole H2 may be provided. Even with such a through hole H2, the groove contact portion 23 can be satisfactorily locked to the peripheral wall of the through hole H2. Therefore, the sealing member 20 becomes difficult to get out of the groove 11d in which the through hole H2 is formed.

Further, in a modified example of the door hole cap 1 , the fixing region 18 may be a region in which the width of the groove 11 is formed narrower than the portion other than the fixing region 18 instead of forming the through hole. The narrower the width of the groove 11, the more difficult it is for the sealing member 20 inserted into the groove 11 to escape. In this case, according to the configuration in which the fixing region 18 is intermittently provided at a plurality of locations instead of the entire circumference of the door hole cap 1, an excessive force is not required for inserting the sealing member 20, and the sealing member 20 can be removed. It can be difficult to escape.

Further, in a modified example of the door hole cap 1, the fixing region 18 is formed such that at least a part of the inner surface of the side wall of the groove 11 with which the groove abutment 23 abuts has a greater coefficient of friction than other portions. may For example, in the fixing region 18, the inner surface of the side wall against which the groove contact portion 23 abuts may be processed to reduce flatness, such as texturing or uneven processing. With such a configuration as well, the groove contact portion 23 that contacts the inner surface of the side wall of the groove 11 is less likely to slide against the inner surface of the side wall, so that the sealing member 20 is less likely to slip out of the groove 11 .

[Application example]
An application example to which the configuration of the groove 11 and the sealing member 20 in the door hole cap 1 is applied will be described below with reference to FIGS. 10 and 11. FIG. FIG. 10 is a diagram showing how the air outlet C1 is attached to the automobile C. As shown in FIG. Reference numeral 1101 in FIG. 11 is a view of the air outlet C1 as seen from the outside of the vehicle, and reference numeral 1102 is a cross-sectional view taken along line FF indicated by reference numeral 1101. FIG.

The configurations of the groove 11 and the sealing member 20 provided in the door hole cap 1 can be applied to various plate-like members attached to the automobile C in addition to the door hole cap. In particular, it can be suitably applied to a plate-shaped member that is attached to the automobile C in a manner that requires water stopping. The air outlet C1 shown in FIG. 10 is one example.

The air outlet C1 is attached to an exterior opening C3 of an air duct C2 through which air flows from the interior space of the automobile C. As shown in FIG. The vehicle-exterior opening C3 is formed in an inner panel of a rear bumper C4 of the automobile C. As shown in FIG. The air outlet C1 is a member that improves the ability to close the door by discharging air when closing the door of the automobile C to reduce the increase in the vehicle internal pressure.

Since the air outlet C1 is attached to the vehicle-exterior opening C3 facing the exterior of the automobile C, it is required to have a waterproof property. Conventionally, a waterproof seal made of urethane foam or the like is attached to the periphery of the air outlet to secure water resistance when the air outlet is attached to the vehicle exterior opening C3. However, there is a problem that the process of positioning and adhering the waterproof seal causes an increase in manufacturing cost. Such problems can be solved by applying the configuration of the groove 11 and the sealing member 20 provided in the door hole cap 1 to the air outlet C1.

As indicated by reference numeral 1101 in FIG. 11, the air outlet C1 includes a plate-like main body C11 and a sealing member C13. For the groove C12 formed in the plate-like main body C11 and the seal member C13 inserted into the groove C12, the description of the groove 11 and the seal member 20 included in the door hole cap 1 can be used. The groove C12 of the air outlet C1 has a parallel portion C14 corresponding to the wide portion 17 of the door hole cap 1. As shown in FIG.

The plate-like main body C11 includes an exhaust valve C15 and a fixing portion C16 in addition to the groove C12. The exhaust valve C15 is normally closed, and opens when air pressure is applied from the inside of the vehicle through the air duct C2 to discharge the air to the outside of the vehicle.

As indicated by reference numeral 1102 in FIG. 11, the fixing portion C16 is a member that engages with the peripheral edge portion of the vehicle-exterior opening C3 to fix the air outlet C1 to the vehicle-exterior opening C3. When the air outlet C1 is fixed to the vehicle-exterior opening C3, the sealing member C13 abuts the outer surface of the vehicle-exterior opening C3, so that a high waterproof performance is obtained.

Since the seal member C13 can be manufactured at a low cost by, for example, extrusion molding, the member cost can be reduced as compared with the conventional waterproof seal. Moreover, the attachment of the sealing member C13 to the plate-like main body C11 is completed only by a simple operation of inserting the sealing member C13 into the groove C12. Thus, according to the configuration in which the groove C12 is formed in the plate-like main body C11 and the sealing member C13 is inserted therein, it is possible to reduce the manufacturing cost of the air outlet C1 and ensure a high waterproof performance.
