Description

Technical Field

[0001] This invention relates to a door opening cover and a sealing component. Background Technology

[0002] Traditionally, door opening covers were used to prevent rainwater from entering the interior of car doors through openings formed in the door panels. Typically, a foam material or similar material is attached to the perimeter of the door opening cover to prevent water seepage. However, attaching this material is time-consuming, labor-intensive, and requires skilled workers, thus increasing the workload and manufacturing costs associated with installing the sealing components. Therefore, the industry is looking for a door opening cover that maintains waterproofing while reducing manufacturing costs.

[0003] For example, Patent Document 1 discloses a resin board with foamed sealant, the resin board with foamed sealant comprising: a resin board body having a groove; and a foamed sealant formed by foaming and hardening liquid foamed resin raw material in the groove and bulging out to the surface of the board body.

[0004] [Existing technical documents]

[0005] [Patent Literature]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2009-166421 Summary of the Invention

[0007] [The problem the invention aims to solve]

[0008] However, in the resin board with foamed sealant disclosed in Patent Document 1, the liquid foamed resin raw material is injected into the groove and then allowed to foam and harden. During the injection of the liquid foamed resin raw material into the groove, deviations in the injection amount due to operator error may reduce the waterproofness of the resin board with foamed sealant. Furthermore, the foaming and hardening of the liquid foamed resin raw material takes time, thus increasing the operation time and manufacturing cost. Moreover, once the foamed sealant is formed on the resin board body, it cannot be easily removed. Therefore, even if only the foamed sealant fails after its formation, it must be replaced along with the resin board body, resulting in increased manufacturing costs.

[0009] One aspect of the present invention is made in view of the aforementioned problems, and its object is to provide a door cover, etc., that can maintain the waterproofness of the door cover and reduce manufacturing costs.

[0010] [Technical means to solve the problem]

[0011] To address the aforementioned problem, according to one aspect of the present invention, a door opening cover is installed on a door opening formed in an inner panel of a vehicle door, comprising: a cover member having a groove recessed toward the vehicle interior and covering the door opening from the vehicle interior; and a sealing member installed in the groove, wherein the groove is formed around the entire circumference of a first peripheral portion that is a peripheral portion of the cover member, the sealing member comprising: a body portion inserted into the interior of the groove; a first sealing portion extending from an outer vehicle end of the body portion toward the vehicle exterior and abutting against an inner surface of the inner panel; and a groove-abutting portion extending from a position of the body portion further toward the vehicle interior than the outer vehicle end toward the inner surface of the groove toward at least one side of the groove and abutting against the inner surface.

[0012] According to one aspect of the invention, a sealing member is installed in a door opening cover formed in a door opening on an inner door panel of an automobile, and is installed in a groove formed around the entire circumference of a first peripheral portion of a cover member that covers the door opening from the inside of the vehicle and recesses towards the inside of the vehicle, and includes: a body portion that is inserted into the interior of the groove; a first sealing portion that extends from the outer end of the body portion toward the outer side of the vehicle and abuts against the inner surface of the inner door panel; and a groove abutting portion that extends from a position of the body portion closer to the inner side of the vehicle than the outer end of the vehicle toward the inner surface of at least one side of the groove and abuts against the inner surface.

[0013] [The effects of the invention]

[0014] According to one aspect of the present invention, a door cover or the like that can maintain the waterproofness of the door cover and reduce manufacturing costs can be provided. Attached Figure Description

[0025] Figure 11 This is a diagram showing the structure of an air outlet according to an application example. Detailed Implementation

[0026] <Overview and Installation Example of Doorway Cover 1>

[0027] Reference Figure 1 The outline and installation example of a doorway cover 1 according to one embodiment of the present invention will be described. Furthermore, in Figure 1 In the example, facing the paper, the top corresponds to the top side of the vehicle, the bottom to the bottom side, the right side to the front side, the left side to the rear side, the near side to the inside of the car, and the inner side to the outside of the car. Additionally, Figure 1 This is a diagram showing the front door D as viewed from inside the vehicle. However, this does not restrict the direction in which the door cover 1 is installed on the vehicle; the door cover 1 can be installed in any orientation relative to the vehicle.

[0028] The front door D is an example of a car door, installed in a way that allows it to be opened and closed, with an opening (not shown). The front door D includes an outer door panel (not shown) and an inner door panel D1, in which a door opening D2 is formed. The door opening D2 is an opening for a worker to insert their hands or tools, etc., to repair various components, for example, located inside the front door D. Furthermore, Figure 1 The formation of the front door D shown is just an example. The number and location of the door openings D2 can be changed arbitrarily as needed.

[0029] A door opening cover 1 is installed on the inner side of the door panel D1. The door opening cover 1 prevents rainwater and other substances that have seeped into the interior of the front door D from the gap between the car door glass (not shown) and the outer sealing strip of the body waistline installed on the outer side of the door panel (not shown) from seeping into the interior of the car through the door opening D2 by blocking the door opening D2 from the inside of the car.

[0030] like Figure 1 As shown, the door opening cover 1 includes a cover member 10 and a sealing member 20. The cover member 10 has a groove 11 recessed towards the inside of the vehicle, and is installed on the inner door panel D1 to cover the door opening D2 from the inside of the vehicle. By installing the sealing member 20 in the groove 11, the sealing member 20 abuts against the inner side of the inner door panel D1, thereby preventing rainwater and the like from seeping into the vehicle interior from the door opening D2.

[0031] Furthermore, the installation method of the aforementioned door opening cover 1 is merely an example. For instance, the type of car door with the door opening cover 1 installed is not limited to... Figure 1 The example shown is of the front door D, which can be any type of car door. Therefore, the door cover 1 can also be installed on the rear door or a sliding door (not shown). In addition, the type of car to which the door cover 1 is installed includes any type of car, such as sedans, hardtops, and convertibles.

[0032] <Structure of Doorway Cover 1>

[0033] Reference Figure 2 The structure of the doorway cover 1 will be described. Furthermore, Figure 2 yes Figure 1 The diagram shows a sectional view along line AA of the door opening cover 1 installed on the inner door panel D1. Therefore, in... Figure 2 In the example, facing the paper, the top side corresponds to the top side of the vehicle, the bottom side corresponds to the bottom side of the vehicle, the right side corresponds to the outside of the vehicle (the outside of the car), the left side corresponds to the inside of the vehicle (the inside of the car), the near side corresponds to the front side of the vehicle, and the inside side corresponds to the rear side of the vehicle.

[0034] like Figure 2 As shown, the door cover 1 has a structure in which a sealing member 20 is inserted into a groove 11 formed in the first peripheral portion 12, which serves as the periphery of the cover member 10. The groove 11 is formed around the entire circumference of the first peripheral portion 12. By installing the door cover 1 onto the inner door panel D1, the door cover 1 covers the door opening D2 from the inside of the vehicle, and the sealing member 20 abuts against the inner surface of the inner door panel D1 facing the first peripheral portion 12.

[0035] Viewed from the side of the vehicle, the shape of the cover component 10 is similar to that of the doorway D2, but it is a component that is larger than the doorway D2. For example... Figure 1 and Figure 2As shown, since the sealing member 20 is installed on the first peripheral portion 12, the sealing member 20 becomes a structure that surrounds the door opening D2.

[0036] The material of the cover component 10 may include, for example, vulcanized rubber, thermoplastic elastomers, thermoplastic resins, or metals. Examples of vulcanized rubber 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 olefin-based (TPO) or styrene-based (TPS). Examples of thermoplastic resins include PE (polyethylene), PP (polypropylene), PVA (polyvinyl alcohol), PVC (polyvinyl chloride), PS (polystyrene), ABS (acrylonitrile-butadiene-styrene), and EVA (vinyl acetate). Examples of composites include aggregates of fibers such as glass fiber blends. Examples of metals include aluminum and iron.

[0037] <Structure of sealing component 20>

[0038] Reference Figure 2 and Figure 3 The structure of the sealing member 20 will be described. Furthermore, Figure 3 This is an enlarged cross-sectional view of the sealing member 20. Figure 3 In the example, facing the paper, the top corresponds to the outer side of the car (the outside of the vehicle), and the bottom corresponds to the inner side of the car (the inside of the vehicle). For example... Figure 3 As shown, in this embodiment, the sealing member 20 includes a body portion 21, a first sealing portion 22, a groove portion 23, a lip portion 24, and a second sealing portion 25.

[0039] The body portion 21 is the part inserted into the groove 11. The body portion 21 is formed such that, when inserted into the groove 11, its length from the outer side to the inner side of the vehicle is greater than the depth of the groove 11. A first sealing portion 22 extends from the outer side end of the body portion 21 towards the outer side of the vehicle, and abuts against the inner side surface of the door inner panel D1. A lip-shaped abutment portion 23 extends from a position of the body portion 21 closer to the inner side of the vehicle than the outer side end towards the inner surface of at least one side of the groove 11, and abuts against the inner surface of the groove 11.

[0040] In this embodiment, such as Figure 2 As shown, the abutment portion 23 extends from multiple locations toward the inner surfaces of both sides of the groove 11, but the present invention is not limited thereto. The abutment portion 23 may be provided in such a way that it extends toward at least one side of the groove 11. By abutting against the inner surface of the groove 11, the sealing member 20 can be securely installed in the groove 11.

[0041] Furthermore, the abutment portion 23 extends obliquely outward toward the inner surface of the groove 11. Therefore, when the sealing member 20 is inserted into the groove 11, the abutment portion 23 easily undergoes elastic deformation by bending outward toward the outer surface of the vehicle. Thus, the abutment portion 23 does not easily obstruct the insertion of the sealing member 20 into the groove 11. On the other hand, the abutment portion 23 does not easily bend inward toward the inner surface of the vehicle. Therefore, the sealing member 20 is not easily dislodged from the groove 11. In this way, the abutment portion 23 can prevent the sealing member 20 from accidentally dislodging from the groove 11.

[0042] In addition, such as Figure 2 As shown, even when the groove portion 23 extends into the inner surface of the groove 11 from multiple positions of the body portion 21, it is possible to maintain a state in which the sealing member 20 can be easily inserted into the groove 11, and to form a shape in which the sealing member 20 is more difficult to fall off from the groove 11.

[0043] The sealing member 20, comprising a body portion 21, a first sealing portion 22, and abutment portion 23, is installed on the cover member 10 simply by inserting the sealing member 20 into the groove 11 of the cover member 10. In conventional door opening covers where sponge materials or similar materials are used as sealing members, positioning and bonding operations are required. However, this process is eliminated in the present invention, thus reducing the manufacturing cost of the door opening cover 1.

[0044] Furthermore, the first sealing part 22 abuts against the inner door panel D1, preventing rainwater and other substances from seeping into the vehicle interior through the door opening D2 from outside. The sealing member 20 is a structure that surrounds the door opening D2, and the first sealing part 22 abuts against the inner door panel D1 at the periphery of the door opening D2. Therefore, the door opening cover 1 of the present invention can maintain waterproofness and reduce manufacturing costs.

[0045] like Figure 2 As shown, the sealing member 20 may have a lip 24. The lip 24 extends from the outer end of the body portion 21 toward the second peripheral portions 13, which are the peripheral portions on both sides of the groove 11, and abuts against the second peripheral portions 13 from the outer side of the vehicle. By abutting against the second peripheral portions 13 on both sides of the groove from the outer side of the vehicle, the lip 24 covers the groove 11. As a result, the lip 24 can prevent rainwater and the like from seeping into the groove 11, thus reducing the possibility of rainwater and the like seeping into the interior of the vehicle through the groove 11. Therefore, by using the sealing member 20 with the lip 24, the waterproofness of the door opening cover 1 can be improved compared to the case where the sealing member 20 does not have the lip 24.

[0046] Furthermore, by abutting the second peripheral portions 13 on both sides of the groove 11 with the lip 24, a structure is formed in which the lip 24 supports the sealing member 20 installed in the groove 11 from two directions. Therefore, by using the sealing member 20 with the lip 24, the installation posture of the sealing member 20 installed in the groove 11 can be made more stable compared to the case where the sealing member 20 does not have the lip 24.

[0047] Furthermore, such as Figure 2 As shown, the sealing member 20 may have a second sealing portion 25. The second sealing portion 25 extends in the sealing member 20 from the lip 24 on the end side of the door opening cover 1. More specifically, the second sealing portion 25 extends towards the interior surface of the door inner panel D1 from a position closer to the body portion 21 than the front end of the lip 24 on the end side, and abuts against the interior surface of the door inner panel D1.

[0048] By including a second sealing portion 25 that abuts against the inner door panel D1, the sealing member 20 effectively prevents rainwater and other substances from seeping into the vehicle interior by using both the first sealing portion 22 and the second sealing portion 25. Therefore, by using the sealing member 20 with the second sealing portion 25, the waterproofness of the door opening cover 1 can be improved compared to the case where the sealing member 20 does not include the second sealing portion 25.

[0049] Furthermore, the second sealing portion 25 extends from the lip 24. Therefore, the force applied from the inner door panel D1 to the inside of the vehicle through the second sealing portion 25 abuts against the inner door panel D1 and acts on the lip 24. Thus, the lip 24 is forcefully pressed against the second peripheral portion 13 from the outside of the vehicle, thereby effectively preventing rainwater and the like from seeping in from the groove 11.

[0050] The components constituting the sealing member 20 can be primarily formed from vulcanized rubber, thermoplastic elastomers, thermoplastic resins, etc. For example, EPDM, IR (isoprene rubber), CR (chloroprene rubber), styrene-butadiene rubber (SBR), and acrylonitrile-butadiene rubber (NBR) can be used as vulcanized rubber. For example, olefin-based (TPO) or styrene-based (TPS) materials can be used as thermoplastic elastomers. For example, polyethylene (PE) or polypropylene (PP), ethylene vinyl acetate copolymer (EVA), or soft polyvinyl chloride can be used as thermoplastic resins. The material can be solid, foamed sponge-like, or partially foamed sponge-like with other parts being solid.

[0051] The first sealing portion 22 can be formed in a softer manner than the main body portion 21. Here, "soft" refers not only to the material's inherent softness but also to a shape that is easily deformable, such as a hollow shape. When the first sealing portion 22 is softer than the main body portion 21, it is easier to bend when pressed against the inner door panel D1, thus ensuring a tight seal between them. Furthermore, since the main body portion 21 is less prone to bending than the first sealing portion 22, it is less likely to deform, thus easily maintaining the sealing member 20 stably installed in the groove 11. Therefore, the door opening cover 1 can reliably maintain high waterproof performance.

[0052] The first sealing portion 22 may be formed primarily of the same material as the sealing member 20. In this case, it is preferable that the body portion 21 is solid, while the first sealing portion 22 is formed as a foamed sponge. For example, it is particularly preferable that the first sealing portion 22 is formed of a high-expansion EPDM.

[0053] The sealing member 20 can be manufactured by extrusion molding. By using extrusion molding to manufacture the sealing member 20, for example, when manufacturing the first sealing part 22 and the body part 21 using different materials, it is easier and cheaper to manufacture than other manufacturing methods such as die forming. However, the present invention is not limited to this, and the sealing member 20 can also be manufactured by conventional manufacturing methods.

[0054] <Structure of slot 11>

[0055] Reference Figure 1 and Figure 4 The structure of the groove 11 of the cover component 10 will be described. Figure 4 The symbol 401 represents Figure 1 The diagram shows a cross-sectional view along the BB line of the door opening cover 1 installed on the inner panel D1 of the door. Figure 4 The symbol 402 represents Figure 1 The diagram shows a cross-sectional view along the CC line of the door opening cover 1 installed on the inner panel D1 of the door. Figure 4 The symbol 403 represents Figure 1 The diagram shows a cross-sectional view along line DD of the door opening cover 1 installed on the inner panel D1 of the door. Figure 4 In the example, facing the paper, the top corresponds to the inside of the car, the bottom corresponds to the outside of the car, the right side corresponds to the front side, the left side corresponds to the rear side, the near side corresponds to the bottom of the car, and the inside side corresponds to the top of the car.

[0056] In this embodiment, such as Figure 1As shown, a side-by-side portion 16 is formed as part of the groove 11, with one end 14 and the other end 15 facing each other and arranged side-by-side on the surface of the cover member 10 in which the groove 11 is formed. A wide portion 17, which is part of the side-by-side portion 16, is formed such that one end 14 and the other end 15 are connected, and the width of the groove 11 is wider than the other portions. A detailed description follows.

[0057] Figure 4 Symbol 401 is a cross-sectional view showing the sealing member 20 inserted into the region 11a of the groove 11, excluding the side-by-side portion 16. Region 11a in the groove 11 is capable of inserting one row of sealing members 20, and the groove is formed with a width suitable for inserting one row of sealing members 20. Furthermore, Figure 4 Symbol 402 is a cross-sectional view of the region 11b of the wide portion 17 in the groove 11, in which the sealing member 20 is inserted. Region 11b in the groove 11 is capable of inserting two rows of sealing members 20, forming a groove of width suitable for the side-by-side insertion of two rows of sealing members 20. Furthermore, Figure 4 The symbol 403 is a cross-sectional view of the region 11c at both ends of the side-by-side portion 16 in the groove 11 when the sealing member 20 is inserted. The region 11c in the groove 11 is capable of inserting a row of sealing members 20, and the side-by-side grooves are formed with a width suitable for inserting a row of sealing members 20.

[0058] When the aforementioned side-by-side portion 16 is formed on the cover member 10 as part of the groove 11, the sealing member 20 can be reliably installed around the entire circumference of the first peripheral portion 12. When the side-by-side portion 16 is not formed on the cover member 10, the groove 11 formed around the entire circumference of the first peripheral portion 12 is simply its entirety. Figure 4 The width of region 11a is indicated by symbol 401. Therefore, when the sealing member 20 is inserted into the groove 11, manufacturing deviations, etc., cause the length of the sealing member 20 to become shorter, and the ends of the sealing members 20 cannot abut against each other, resulting in reduced water tightness. Therefore, there is a situation where the sealing member 20 fails to seal properly on the first peripheral portion 12.

[0059] On the other hand, when the side-by-side portions 16 are formed on the cover member 10, a portion of the groove 11 is Figure 4 The width of region 11b is shown by symbol 402. Additionally, it can be seen as... Figure 4 As shown in region 11c by symbol 403, grooves 11 are formed side by side on the cover member 10. Therefore, even if there are manufacturing deviations in the sealing member 20, for example, the two ends of the sealing member 20 are partially mounted side by side on the side-by-side portion 16, thus preventing the formation of insufficient sealing on the first peripheral portion 12.

[0060] Furthermore, in this embodiment, a region 11b with a wide groove 11 is formed in the wide portion 17, while a region 11c with two grooves 11 side by side is formed at both ends of the side-by-side portion 16. Here, two rows of sealing members 20 are inserted into one groove 11 in the wide portion 17, resulting in a very small number of tubular passages S formed along the groove 11, which are surrounded by the sealing members 20 and the inner door panel D1.

[0061] For example, when the end of the groove 11 on the lower side of the vehicle (one end 14 in this embodiment) becomes a wide portion 17, rainwater and the like can easily cling to the passage S formed at one end 14. If rainwater or the like clings to the passage S, there is a possibility that the passage S absorbs rainwater or the like due to capillary action, causing rainwater or the like to seep into the vehicle interior. On the other hand, when region 11c is formed on the lower side of the vehicle in the side-by-side section 16, the passage S formed at one end 14 is located in the side-by-side section 16, closer to the upper side of the vehicle than the lower end of the sealing member 20 on the door opening D2 side. Therefore, rainwater or the like is less likely to cling to this passage S, thereby reducing the possibility of rainwater or the like seeping into the groove 11 due to capillary action. Therefore, compared to the case where the groove 11 is connected in the entire side-by-side section 16 to form a wide portion 17, the waterproofness of the door opening cover 1 can be improved.

[0062] However, the present invention is not limited to the structure of the groove 11 described above. The groove 11 can be formed around the entire circumference of the first peripheral portion 12.

[0063] <Drainage Structure>

[0064] Reference Figure 5 The drainage structure will be described. Furthermore... Figure 5 yes Figure 1 The diagram shows a cross-sectional view along line EE of the door opening cover 1 installed on the inner door panel D1. Therefore, in... Figure 5 In the example, facing the paper, the top side corresponds to the top of the vehicle, the bottom side corresponds to the bottom of the vehicle, the right side corresponds to the outside of the vehicle, the left side corresponds to the inside of the vehicle, the near side corresponds to the front side, and the inside side corresponds to the rear side.

[0065] In this embodiment, such as Figure 5As shown, the door opening cover 1 may have a drainage structure for draining water between the first sealing part 22 and the second sealing part 25. Specifically, a drainage hole D3 may be provided on the inner door panel D1 at the lower part of the door opening D2. Through the drainage hole D3, even if rainwater, for example, from the door opening D2 reaches the first sealing part 22 and seeps into the space between the first sealing part 22 and the second sealing part 25, the seeping rainwater will move to the lower part of the inner door panel D1 under gravity and be discharged from the drainage hole D3. Therefore, the drainage hole D3 can complement the shape of the separation between the first sealing part 22 and the second sealing part 25 to form a drainage structure, thereby improving the waterproofness of the door opening cover 1.

[0066] [Variation Example]

[0067] (Modified example of sealing member 20)

[0068] Regarding the door opening cover 1 and sealing member 20 according to this embodiment, several variations are assumed. Hereinafter, using... Figure 6 and Figure 7 A modified example of the door opening cover 1 and sealing member 20 according to this embodiment will be described. Figure 6 The symbol 601 is a cross-sectional view of the sealing member 201 according to a modified embodiment of the present invention. Figure 7 The symbol 701 is a cross-sectional view of the sealing member 202 according to a modified embodiment of the present invention. Figure 6 The symbol 602 is a cross-sectional view of the door opening cover 2 according to a variation of the present invention. Figure 7 The symbol 702 is a cross-sectional view of the door opening cover 3 according to a variation of the present invention.

[0069] exist Figure 6 The symbol 601 and Figure 7 In the example of symbol 701, facing the paper, the upper side corresponds to the outer side of the car (the outside of the vehicle), and the lower side corresponds to the inner side of the car (the inside of the vehicle). Additionally, in... Figure 6 The symbol 602 and Figure 7 In the example of symbol 702, facing the paper, the upper side corresponds to the inner side of the vehicle, the lower side corresponds to the outer side of the vehicle, the right side corresponds to the front side of the vehicle, the left side corresponds to the rear side of the vehicle, the near side corresponds to the lower side of the vehicle, and the inner side corresponds to the upper side of the vehicle.

[0070] like Figure 6 As indicated by symbol 601, the shape of the first sealing portion 221 of the sealing member 201 differs from that of the sealing member 20. For example... Figure 6As indicated by symbol 602, compared to the first sealing portion 22 of the sealing member 20, the contact area between the first sealing portion 221 and the inner door panel D1 is increased by enlarging the cross-section of the first sealing portion 221. With this structure, rainwater and other substances are less likely to seep into the interior of the vehicle through the first sealing portion 221, thus improving the waterproofness of the door opening cover 2. Furthermore, as... Figure 6 As indicated by symbol 602, in the wide portion 17, when two rows of sealing members 201 are inserted into the groove 11, a structure can be provided in which gaps are not easily formed between the sealing members 201, thereby improving the waterproofness of the door opening cover 2.

[0071] Then, as Figure 7 As indicated by symbol 701, the shape of the body portion 211 of the sealing member 202 differs from that of the sealing member 20. By making the length of the body portion 211 in the direction from the outer side to the inner side of the vehicle shorter than that of the body portion 21 of the sealing member 20, the material required to manufacture the sealing member 202 is reduced, thereby lowering the manufacturing cost of the door opening cover 3. Furthermore, as... Figure 7 As indicated by symbol 702, the depth of the groove 11 in the cover member 101 can be shortened because the cross-section of the body portion 211 of the sealing member 202 is short. Therefore, the material required to manufacture the cover member 101 is reduced, thereby lowering the manufacturing cost of the door opening cover 3. Furthermore, the sealing member 202 can be easily inserted deep into the groove 11.

[0072] (A variation of slot 11)

[0073] The following uses Figure 8 and Figure 9 A modified example of the groove 11 in the door opening cover 1 according to this embodiment will be described. Figure 8 The symbol 801 is in the door cover 4 of a variation of the present invention, and Figure 1 A cross-sectional view of the arrow at the same location as the BB line. Additionally, Figure 8 The symbol 802 is in the doorway cover 5 according to a variation of the present invention, and is related to Figure 1 The arrow view section at the same position as the BB line.

[0074] like Figure 8 As indicated by symbol 801, the doorway cover 4 includes a cover member 102, which differs from the doorway cover 1 in that it has a groove 11c with a through hole H1 formed therein. The through hole H1 is formed by cutting approximately half of the bottom side of the groove 11c in the depth direction. If a sealing member 20 is inserted into this groove 11c, at least a portion of the abutment portion 23 is inserted into the through hole H1. Even if the sealing member 20 is about to come out, the abutment portion 23 inserted into the through hole H1 will be stopped by the peripheral wall of the through hole H1. Thus, the doorway cover 4 preferably has a through hole H1 formed in at least a portion of the groove 11c for at least a portion of the abutment portion 23 to be inserted.

[0075] The groove 11c can be formed into a tapered shape that narrows towards the bottom to facilitate demolding during manufacturing. In this case, the sealing member 20 can also be easily removed from the groove 11c, similar to the mold. However, the groove 11c includes a through hole H1, which is stopped by the peripheral wall of the through hole H1 by the groove abutment 23, thus preventing the sealing member 20 from being removed from the groove 11c.

[0076] like Figure 9 As shown, it is preferable to provide a plurality of fixing regions 18 on the groove 11c included in the door opening cover 4. The fixing regions 18 are areas formed in a manner that facilitates the fixing of the sealing member 20 to the groove 11c, and are areas where a through hole H1 is formed in the door opening cover 4. The fixing regions 18 are preferably provided not only at the straight portions of the groove 11c formed in a straight line, but also at the corner portions formed by the curvature of the groove 11c around the periphery of the door opening cover 4. In such corner portions, since the posture of the sealing member 20 is difficult to stabilize within the groove 11c, it is particularly preferable to make a structure in which the sealing member 20 is not easily dislodged from the groove 11c.

[0077] In addition, such as Figure 8 Similar to the door cover 5 shown by symbol 802, a through hole H2 can also be provided in the fixed area 18. This through hole H2 is formed only in the narrow portion where the sealing member 20 is abutted by any groove 23 when inserted deeply. Even with this through hole H2, the groove 23 can be well locked by the peripheral wall of the through hole H2. Therefore, the sealing member 20 is not easily dislodged from the groove 11d where the through hole H2 is formed.

[0078] In another variation of the door opening cover 1, the fixing region 18 may be a region where the width of the groove 11 is narrower than the portion outside the fixing region 18, thus not forming a through hole. The narrower the width of the groove 11, the less likely the sealing member 20 inserted into the groove 11 will fall out. In this case, because the fixing region 18 is not provided on the entire circumference of the door opening cover 1 but is intermittently provided in multiple locations, the insertion of the sealing member 20 does not require excessive force, and the sealing member 20 is less likely to fall out.

[0079] In another variation of the door opening cover 1, the fixing region 18 may be formed on the inner sidewall of the groove 11 such that the coefficient of friction of at least a portion of the abutment portion 23 is greater than that of other portions. For example, in the fixing region 18, the inner sidewall of the abutment portion 23 may be processed to reduce flatness, such as by wrinkling or uneven processing. With this structure, the abutment portion 23 abutting against the inner sidewall of the groove 11 is less likely to slide relative to the inner sidewall, and therefore the sealing member 20 is less likely to detach from the groove 11.

[0080] [Application Example]

[0081] The following uses Figure 10 and Figure 11An application example of the structure of the groove 11 and sealing member 20 in the door opening cover 1 will be described. Figure 10 This diagram shows how air vent C1 is installed on car C. Figure 11 Symbol 1101 is a view of the air vent C1 as seen from the outside of the vehicle, and symbol 1102 is a cross-sectional view of the FF line arrow shown in symbol 1101.

[0082] The structure of the groove 11 and sealing member 20 included in the door opening cover 1 can be applied not only to door opening covers but also to various plate-shaped components installed in automobiles C. In particular, it can be appropriately applied to plate-shaped components installed in automobiles C when waterproofing is required. Figure 10 The air outlet C1 shown is an example.

[0083] Air vent C1 is installed on the outer side opening C3 of the air duct C2 that allows air to flow from the interior space of the car C. The outer side opening C3 is formed on the inner side panel of the rear bumper C4 of the car C. Air vent C1 is a component that improves the door sealing performance by expelling air when the car C door is closed, thereby reducing the rise in interior pressure.

[0084] Since the air vent C1 is installed on the exterior opening C3 facing the vehicle C, waterproofing is required. Previously, waterproof sealant such as polyurethane foam was applied to the periphery of the air vent to ensure waterproofing when installed on the exterior opening C3. However, the process of positioning and bonding the waterproof sealant became a major reason for increased manufacturing costs. This problem can be solved by applying the structure of the groove 11 and sealing member 20 included in the door opening cover 1 to the air vent C1.

[0085] like Figure 11 As indicated by symbol 1101, the air outlet C1 includes a plate-shaped body C11 and a sealing member C13. The groove C12 formed in the plate-shaped body C11 and the sealing member C13 inserted into the groove C12 are respectively referred to in the description of the groove 11 and the sealing member 20 included in the door opening cover 1. The groove C12 of the air outlet C1 includes a side-by-side portion C14 corresponding to the width portion 17 of the door opening cover 1.

[0086] The plate-shaped body C11, in addition to the groove C12, includes an exhaust valve C15 and a fixing part C16. The exhaust valve C15 is normally closed, but it will open when air pressure is applied to it from the inside of the vehicle through the air pipe C2, thus venting air to the outside of the vehicle.

[0087] like Figure 11 As indicated by symbol 1102, the fixing part C16 is a component that locks onto the peripheral end of the outer side opening C3 of the vehicle to fix the air outlet C1 to the outer side opening C3 of the vehicle. After the air outlet C1 is fixed to the outer side opening C3 of the vehicle, the sealing member C13 abuts against the outer surface of the outer side opening C3 of the vehicle, thus achieving high water resistance.

[0088] The sealing component C13 can be manufactured inexpensively, for example, through extrusion molding, thus reducing component costs compared to conventional waterproof seals. Furthermore, the installation of the sealing component C13 onto the plate-shaped body C11 is completed simply by inserting it into the groove C12. In this way, by forming the groove C12 in the plate-shaped body C11 and inserting the sealing component C13 therein, the manufacturing cost of the air outlet C1 can be reduced while ensuring high waterproof performance.

[0089] 〔Summarize〕

[0090] To address the aforementioned problem, according to one aspect of the invention, a door opening cover is installed in a door opening formed in the inner panel of a vehicle, comprising: a cover member having a groove recessed towards the vehicle interior and covering the door opening from the vehicle interior; and a sealing member installed in the groove, wherein the groove is formed over the entire circumference of a first peripheral portion that is a peripheral portion of the cover member, the sealing member comprising: a body portion inserted into the interior of the groove; a first sealing portion extending from the vehicle exterior end of the body portion toward the vehicle exterior and abutting against the vehicle interior surface of the inner panel; and a groove-abutting portion extending from a position of the body portion further into the vehicle interior than the vehicle exterior end toward the inner surface of at least one side of the groove and abutting against the inner surface.

[0091] According to the described structure, the installation of the sealing member on the cover member is completed simply by inserting the sealing member into the groove of the cover member. Therefore, the positioning and bonding work required when attaching materials such as sponge to the door opening cover is eliminated, reducing the likelihood of manufacturing deviations due to varying skill levels. Furthermore, if only the sealing member fails after installation on the cover member, only the sealing member can be easily replaced. Thus, the manufacturing cost of the door opening cover can be reduced.

[0092] Furthermore, according to the aforementioned structure, the first sealing portion installed on the first periphery of the door opening cover abuts against the inner door panel. This maintains the waterproofness of the door opening cover and reduces manufacturing costs.

[0093] For a door opening cover according to one aspect of the invention, the sealing member may include a lip that extends from the outer side end of the body portion toward a second peripheral portion that serves as both sides of the groove, and abuts against the second peripheral portion from the outer side of the body portion.

[0094] According to the structure described, the lip portion abuts against the second peripheral portion of the two sides of the groove from the outside of the vehicle, thus covering the groove. This reduces the possibility of rainwater or other substances seeping into the groove. Therefore, compared to a sealing member without a lip portion, the waterproofing performance of the sealing member can be improved.

[0095] Furthermore, according to the aforementioned structure, the lip abuts against the second peripheral portions on both sides of the groove, forming a structure in which the lip supports the sealing member installed in the groove from both sides. Therefore, compared to the case where the sealing member does not include the lip, the installation posture of the sealing member installed in the groove is more stable.

[0096] A door cover according to one invention may include a second sealing portion that extends from the end side of the lip of the door cover, closer to the front end of the lip than the body portion, toward the interior surface of the door panel and abuts against the interior surface of the door panel.

[0097] According to the structure described, by including a second sealing portion abutting against the inner door panel, the first and second sealing portions effectively prevent rainwater and other substances from seeping into the vehicle interior. Therefore, compared to a sealing member that does not include a second sealing portion, the waterproofness of the door opening cover can be improved.

[0098] Furthermore, the second sealing portion extends from the lip. Thus, the force applied from the inner door panel towards the inside of the vehicle through the second sealing portion abuts against the inner door panel. Therefore, by forcefully pressing the lip against the second periphery from the outside of the vehicle, it is possible to effectively prevent rainwater and other substances from seeping into the groove.

[0099] According to one aspect of the invention, a door cover may form side-by-side portions on the cover member as part of the groove, the side-by-side portions being formed with one end of the groove facing the other end, and the one end and the other end being formed side-by-side in the direction of the surface of the cover member in which the groove is formed, a portion of the side-by-side portions being connected by the one end and the other end, and the width of the groove being greater than the other portions.

[0100] According to the structure described, a parallel portion is formed in the groove formed in the cover member. When the parallel portion is not formed in the groove, manufacturing deviations or the like can cause the ends of the sealing members to fail to abut each other in a watertight manner, resulting in a situation where the sealing member fails to seal properly at the first periphery. On the other hand, in the cover member, the two ends of the sealing member are partially mounted side by side in the parallel portion, thus preventing the occurrence of a seal failure.

[0101] Furthermore, in one section of the side-by-side section, the grooves are connected to each other, while in the other sections, the grooves are not connected, thus forming two grooves side-by-side. With this structure, even in the section where the ends of the grooves are connected, where a small passage is formed between the two abutting sealing members and the inner door panel, the possibility of rainwater seeping into the groove due to capillary action can be reduced. Therefore, compared to the case where the grooves are connected throughout the entire side-by-side section, the waterproofness of the door opening cover can be improved.

[0102] Furthermore, it is preferable to first install the sealing member on the doorway side in the side-by-side section where the grooves are connected. Thus, between the first sealing member and the groove abutment, the second sealing member folds, and in the side-by-side section where the grooves are connected, the first sealing members of the two abutting sealing members can also abut against each other, thereby further improving waterproofing.

[0103] For a door opening cover according to one aspect of the invention, the first sealing portion may be softer than the body portion. According to this structure, when the first sealing portion is pressed against the inner door panel, it bends and easily seals against the inner door panel, while the body portion is less prone to bending than the first sealing portion, thus preventing deformation. Therefore, the sealing member can easily maintain a stable installation in the groove while providing high water resistance.

[0104] According to one aspect of the invention, a sealing member is installed in a door opening cover formed in a door opening in an inner door panel of an automobile, and is installed in a groove formed on the entire circumference of a first peripheral portion of a cover member that covers the door opening from the inside of the vehicle and recesses towards the inside of the vehicle, and includes: a body portion that is inserted into the interior of the groove; a first sealing portion that extends from the outer end of the body portion toward the outer side of the vehicle and abuts against the inner surface of the inner door panel; and a groove abutting portion that extends from a position of the body portion further toward the inner side of the vehicle than the outer end of the vehicle and toward the inner surface of at least one side of the groove and abuts against the inner surface.
