Description

[Technical field]

[0001] The present invention relates to a door hole cover. [Background technology]

[0002] 2. Description of the Related Art Door hole covers have been used to cover service holes formed in inner door panels of vehicle doors. The door hole covers are attached to the inner door panel from the inside of the vehicle by clips.

[0003] For example, Patent Document 1 describes a door structure in which a door hole cover that covers a service hole formed in the door inner panel is attached to the door inner panel. The door hole cover is attached to the door inner panel by fitting a clip into a mounting hole of the door hole cover.

[0004] Patent Document 2 describes a clip mounting seat that allows a clip to be easily attached to an automobile interior part. A clip inserted into the introduction groove of the clip mounting seat fits into a circular hole of the clip mounting seat. The clip mounting seat is formed with anti-slip protrusions located on both sides of the introduction groove, and the anti-slip protrusions come into contact with the clip flange to prevent the clip from falling out of the circular hole. The width of the introduction groove is set to be larger than the width of the clip shaft, and the clip is formed so that the clip flange bends to overcome the anti-slip protrusions when the clip is inserted.

[0005] [Patent Document 1] JP 2016-78775 A [Patent Document 2] Japanese Utility Model Application Publication No. 61-150509 Summary of the Invention [Problem to be solved by the invention]

[0006] By the way, it is considered that by applying the technology of Patent Document 2 to the technology of Patent Document 1, the work efficiency of the installation work for installing the door hole cover to the door inner panel can be improved.

[0007] However, when removing the door hole cover from the door inner panel, the anti-removal protrusions formed on both sides of the guide groove cause interference between the tool used for the removal work and the anti-removal protrusions, making it impossible to insert the tool between the door inner panel and the door hole cover, which can make the removal work difficult.

[0008] An object of one aspect of the present invention is to improve the efficiency of a removal operation for removing a door hole cover from a door inner panel. [Means for solving the problem]

[0009] In order to solve the above problems, a door hole cover according to a first aspect of the present invention is a door hole cover attached to a door inner panel of a vehicle door, comprising: a cover member that blocks a door hole formed in the door inner panel from the inside of the vehicle; a plurality of recesses provided on the periphery of the cover member for accommodating clips for attaching the door hole cover to the door inner panel; a pair of opposing guide walls that are connected to ends of the recesses where openings of the recesses are formed and guide the clips into the recesses; and a protrusion that protrudes from one of the pair of guide walls, wherein at least a portion of one of the pair of guide walls protrudes in a direction narrowing a space formed between the pair of guide walls more than the other guide wall, and movement of the clip from a state accommodated inside the recess toward the space is regulated by at least a portion of the one of the guide walls abutting against the clip, and movement of the clip from a state accommodated inside the recess through the space toward the outside of the space is regulated by the protrusion abutting against the clip.

[0010] According to the above-mentioned configuration, no protrusion is formed on one of the pair of guide walls. Therefore, by using a tool for removing the door hole cover from the door inner panel from the guide wall side where no protrusion is formed, the door hole cover can be removed from the door inner panel without interference between the protrusion formed on the guide wall and the tool. This improves the work efficiency of removing the door hole cover from the door inner panel.

[0011] A door hole cover according to a second aspect of the present invention is similar to the door hole cover of the first aspect, in that the inner surface of the other guide wall is flush with the inner surface of the recess on the side connected to the other guide wall.

[0012] According to the above-mentioned configuration, since the inner surface of the other guide wall and the inner surface of the recess are flush with each other, when the clip is inserted into the recess, the movement of the clip in the insertion direction is not easily impeded by the other guide wall. This makes it easier to insert the clip into the recess by moving the clip along the other guide wall.

[0013] A door hole cover according to a third aspect of the present invention is the door hole cover according to the first or second aspect, wherein the protrusion is formed on the other guide wall.

[0014] According to the above-mentioned configuration, the clip abuts against at least a portion of one of the guide walls that protrudes in a direction narrowing the space formed between the pair of guide walls, and the clip abuts against a protrusion formed on the other guide wall, thereby restricting movement of the clip toward the outside of the recess, thereby more reliably preventing the clip from falling out of the recess.

[0015] In the door hole cover according to a fourth aspect of the present invention, in addition to the third aspect, the protruding portion protrudes from the surface of the other guide wall facing the vehicle exterior.

[0016] According to the above-mentioned configuration, the protrusion is formed on the surface of the other guide wall facing the vehicle exterior. Therefore, a reinforcing portion such as a rib for reinforcing the guide wall can be formed on the surface of the other guide wall facing the vehicle interior. This allows for flexibility in the shape of the other guide wall facing the vehicle interior. Effect of the Invention

[0017] According to one aspect of the present invention, the work efficiency of removing a door hole cover from a door inner panel can be improved. [Brief description of the drawings]

[0018] [Figure 1] 1 is a schematic diagram showing the structure of the vehicle interior side of a door inner panel to which a door hole cover according to one embodiment is attached. [Diagram 2] FIG. 2 is a side view of the door hole cover shown in FIG. 1 as viewed from the vehicle interior side. [Diagram 3] 1 is a side view of a clip base of the door hole cover as viewed from the vehicle exterior side. FIG. [Figure 4] 13 is a view of the clip base of the door hole cover as seen from the tip side of the guide wall. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] [Door hole cover overview and installation example] With reference to Figs. 1 and 2, an overview and an example of installation of a door hole cover 1 according to an embodiment of the present invention will be described. Fig. 1 is a schematic diagram showing the structure of the vehicle inner side of a door inner panel D1 to which a door hole cover 1 is attached. Fig. 2 is a side view of the door hole cover 1 shown in Fig. 1 as viewed from the vehicle inner side. In the example of Fig. 1, the upper side corresponds to the vertical upper side, the lower side corresponds to the vertical lower side, the right side corresponds to the front side (front side of the vehicle), the left side corresponds to the rear side (rear side of the vehicle), the near side corresponds to the vehicle inner side (inside of the vehicle), and the far side corresponds to the vehicle outer side (outside of the vehicle). This is the same for Fig. 2. Fig. 1 is also a view of a front door D as viewed from the vehicle inner side. However, this does not limit the direction in which the door hole cover 1 is attached to the vehicle, and the door hole cover 1 may be attached to the vehicle in any direction.

[0020] The front door D is an example of a vehicle door, and is attached to a front door opening (not shown) of the vehicle so as to be openable and closable. The front door D includes a door outer panel (not shown) and a door inner panel D1, and a door hole D2 and a speaker mounting hole 2 are formed in the door inner panel D1. The door hole D2 is an opening through which a worker can insert his / her hand or a work tool, for example, to assemble various parts arranged inside the front door D. The speaker mounting hole 2 is an opening into which a speaker is attached. Note that the formation mode of the front door D shown in FIG. 1 is merely one example.

[0021] A door hole cover 1 is attached to the vehicle interior surface of the door inner panel D1. The door hole cover 1 blocks the door hole D2 from the vehicle interior, thereby preventing rainwater or the like that has entered the inside of the front door D from entering the vehicle compartment through the door hole D2. In addition, the door hole cover 1 improves the soundproofing of the front door D by blocking the door hole D2.

[0022] As shown in FIG. 1 and FIG. 2, the door hole cover 1 has a cover member 10 and a clip base 20. The cover member 10 is a member that closes the door hole D2 from the inside of the vehicle as a part of the door hole cover 1. As shown in FIG. 2, a plurality of clip bases 20 are provided on the periphery 101 of the cover member 10. The clips 30 are fitted into through holes (not shown) formed in the door inner panel D1. The clip base 20 of the door hole cover 1 is attached to the clip 30 fitted into the door inner panel D1. The door hole cover 1 is attached to the door inner panel D1 by attaching the clip 30 to the clip base 20. In FIG. 1 and FIG. 2, the reference numerals of the clip base 20 and the clip 30 are given to only one of the plurality of clip bases 20 and the clip 30 in consideration of ease of viewing the drawings, and the reference numerals of the others are omitted.

[0023] The cover member 10 is made of, for example, vulcanized rubber, thermoplastic elastomer, thermoplastic resin, or metal. 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 molding resins include PE (polyethylene), PP (polypropylene), PVA (polyvinyl alcohol), PVC (polyvinyl chloride), PS (polystyrene), ABS (acrylonitrile-butadiene-styrene), or EVA (ethylene vinyl acetate). Examples of composites include an assembly of fibers such as a glass fiber blend. Examples of metals include aluminum or iron.

[0024] The above-mentioned manner of mounting the door hole cover 1 is merely an example. For example, the vehicle door to which the door hole cover 1 is mounted is not limited to the front door D shown in the example of FIG. 1, and may be any type of vehicle door. Therefore, the door hole cover 1 may be mounted, for example, on a rear door or a sliding door. In addition, the vehicle to which the door hole cover 1 is mounted may be any type of vehicle, including hardtop cars and convertible cars.

[0025] [Structure of clip base 20] The detailed structure of the clip base 20 of the door hole cover 1 will be described with reference to Figures 3 and 4. Figure 3 is a side view of the clip base 20 of the door hole cover 1 as viewed from the vehicle exterior. Figure 4 is a view of the clip base 20 of the door hole cover 1 as viewed from the tip ends 222, 232 of the guide walls 22, 23. Reference numeral 1000 in Figure 4 indicates a state in which the clip 30 is accommodated in the clip base 20, and reference numeral 1001 in Figure 4 indicates a state in which the clip 30 is not accommodated in the clip base 20.

[0026] In Fig. 3, the front side of the paper corresponds to the inside of the vehicle, and the back side corresponds to the outside of the vehicle. In addition, in the diagram shown in Fig. 4, the upper side of the paper corresponds to the inside of the vehicle, and the lower side corresponds to the outside of the vehicle. In the following explanation, since the multiple clip bases 20 provided on the cover member 10 all have the same configuration, only one clip base 20 will be explained.

[0027] The clip base 20 is a part of the door hole cover 1 and has a structure for attaching the cover member 10 to the door inner panel D1. As shown in FIG. 3, the clip base 20 has a recess 21 and a pair of guide walls 22, 23. The recess 21 is connected to the periphery 101 of the cover member 10. The recess 21 accommodates a clip 30 for attaching the door hole cover 1 to the door inner panel D1. The recess 21 has an accommodating hole 211 which is a portion recessed in an arc shape. The accommodating hole 211 may be rectangular or polygonal. The door hole cover 1 is attached to the door inner panel D1 by accommodating the clip 30 in the accommodating hole 211.

[0028] Here, an example of the configuration of the clip 30 will be described with reference to Fig. 4. As indicated by reference numeral 1000 in Fig. 4, the clip 30 has a head 31, a shaft 32, a first flange 33, and a second flange 34. The head 31 of the clip 30 is a portion that fits into a through hole of the door inner panel D1. The shaft 32 of the clip 30 is connected to the head 31. When the clip 30 is accommodated inside the recess 21, the shaft 32 is located inside the accommodation hole 211. The outer diameter of the shaft 32 is smaller than the outer diameter of the head 31.

[0029] A first flange portion 33 is formed at a connection portion between the head portion 31 and the shaft portion 32. The first flange portion 33 extends radially outward from the shaft portion 32. The first flange portion 33 abuts against the surface of the clip base 20 on the vehicle exterior side, thereby restricting the movement of the door hole cover 1 toward the vehicle exterior side relative to the door inner panel D1. The second flange portion 34 is formed at an end portion of the shaft portion 32 on the vehicle interior side, and extends radially outward from the shaft portion 32. The second flange portion 34 abuts against the surface of the clip base 20 on the vehicle interior side, thereby restricting the movement of the door hole cover 1 toward the vehicle interior side relative to the door inner panel D1. The outer diameter of the first flange portion 33 and the outer diameter of the second flange portion 34 are larger than the outer diameter of the receiving hole 211.

[0030] Returning to FIG. 3, the guide wall 22 (one guide wall) and the guide wall 23 (the other guide wall) of the clip base 20 are formed to face each other. In FIG. 3, the areas corresponding to the guide wall 22 and the guide wall 23 are indicated by oblique lines. The inner surface 221 of the guide wall 22 and the inner surface 231 of the guide wall 23 are surfaces facing each other. The guide wall 22 and the guide wall 23 are each connected to an end 217 of the recess 21 in which the opening 216 of the recess 21 is formed. In FIG. 3, the end 217 of the recess 21 is indicated by a broken line. More specifically, the guide wall 22 and the guide wall 23 are connected to the end 217 of the recess 21 so that the opening 216 is located between the guide wall 22 and the guide wall 23 in the facing direction X in which the inner surface 221 of the guide wall 22 and the inner surface 231 of the guide wall 23 face each other.

[0031] An inner surface 221 of the guide wall 22 and an inner surface 231 of the guide wall 23 are connected to an inner surface 212 of the recess 21. The inner surface 212 is the inner surface of the recess 21, and is also the surface that constitutes the accommodating hole 211. The opening 216 is an opening for accommodating the clip 30 in the accommodating hole 211, and is constituted by an end on one side of the accommodating hole 211 and an end on the other side of the accommodating hole 211. One end of the accommodating hole 211 is connected to the inner surface 221 of the guide wall 22, and the other end of the accommodating hole 211 is connected to the inner surface 231 of the guide wall 23.

[0032] The guide walls 22 and 23 guide the clip 30 into the recess 21. More specifically, the shaft portion 32 of the clip 30, inserted from the tip 222 side of the guide wall 22 and the tip 232 side of the guide wall 23, is moved along the inner surface 221 of the guide wall 22 and / or the inner surface 231 of the guide wall 23, whereby the clip 30 is guided into the receiving hole 211 of the recess 21. That is, the clip 30 is guided into the recess 21 through the opening 216 by the inner surface 221 and / or the inner surface 231.

[0033] The guide wall 22 protrudes in a direction narrowing the space 24 formed between the pair of guide walls 22, 23 more than the guide wall 23. That is, when viewed from the inside / outside direction of the vehicle, the inner surface 221 is located at a position closer to the center position 215 than the inner surface 231 in the facing direction X. The center position 215 is the position of the center of the outer diameter of the accommodating hole 211 in the facing direction X. More specifically, if a virtual line Y is a virtual line that passes through the center position 215 of the accommodating hole 211 and is perpendicular to the facing direction X, the inner surface 221 is located at a position closer to the virtual line Y than the inner surface 231 in the facing direction X. Also, the inner surface 221 is located closer to the center position 215 than the end portion 213 of the accommodating hole 211 in the facing direction X. The end portion 213 is one end portion of both ends of the outer diameter of the accommodating hole 211 in the facing direction X, and is located on the guide wall 22 side. The other end 214 of the outer periphery of the accommodation hole 211 in the opposing direction X is located on the guide wall 23 side. Note that it is sufficient that at least a portion of the guide wall 22 protrudes in a direction that narrows the space 24.

[0034] The space 24 is a space formed between the inner surface 221 of the guide wall 22 and the inner surface 231 of the guide wall 23. The space 24 is a space through which the shaft portion 32 of the clip 30 passes when the door hole cover 1 is attached to or detached from the door inner panel D1. The guide wall 22 protrudes in a direction narrowing the space 24, so that the movement of the clip 30 from the state accommodated in the accommodation hole 211 toward the space 24 is restricted by abutting against the protruding portion of the guide wall 22. More specifically, the movement of the clip 30 toward the space 24 is restricted by abutting against the shaft portion 32 of the clip 30, which protrudes in a direction narrowing the space 24 of the guide wall 22. That is, the guide wall 22 prevents the clip 30 from falling off the recess 21.

[0035] The inner surface 231 of the guide wall 23 may be flush with the inner surface 212 on the side connected to the guide wall 23. That is, there is no step at the connection portion between the guide wall 23 and the accommodation hole 211. Since the inner surface 231 of the guide wall 23 and the inner surface 212 of the recess 21 are flush with each other, when the clip 30 is accommodated in the recess 21, the movement of the clip 30 in the accommodation direction is less likely to be impeded on the guide wall 23 side. This makes it possible to easily accommodate the clip 30 in the recess 21 by moving the clip 30 along the guide wall 23.

[0036] Here, "flush" in "the inner surface 231 of the guide wall 23 and the inner surface 212 of the recess 21 are flush" does not mean completely flush. For example, even if a minute step inevitably occurs at the connection between the inner surface 231 and the inner surface 212 during the molding process of the clip base 20, or even if a minute unevenness inevitably occurs on at least one of the inner surfaces 231 and 212, it is still "flush."

[0037] The above-mentioned formation mode of the guide wall 23 is merely an example. It is not limited to a configuration in which the inner surface 231 of the guide wall 23 and the inner surface 212 of the recess 21 are flush with each other. For example, at least a part of the guide wall 23 may be configured to protrude in a direction narrowing the space 24. That is, when viewed from the vehicle interior / exterior direction, the inner surface 231 may be located closer to the center position 215 than the end portion 214 of the accommodation hole 211 in the facing direction X. Even in this case, the guide wall 22 protrudes in a direction narrowing the space 24 than the guide wall 23. That is, when viewed from the vehicle interior / exterior direction, the inner surface 221 is located closer to the center position 215 than the inner surface 231 in the facing direction X.

[0038] As shown in Fig. 3 and Fig. 4, a protrusion 25 that protrudes toward the outside of the vehicle is formed on the surface of the guide wall 23 on the vehicle exterior side. As shown in Fig. 3, the protrusion 25 is preferably formed near the tip 232 of the guide wall 23. As shown by reference numeral 1000 in Fig. 4, the protrusion 25 can abut against the first flange portion 33 of the clip 30. The abutment between the protrusion 25 and the first flange portion 33 of the clip 30 restricts the movement of the clip 30 from a state housed inside the recess 21 through the space 24 toward the outside of the space 24. That is, the protrusion 25 of the guide wall 23 prevents the clip 30 from falling off the recess 21.

[0039] 4, a base rib 27 for reinforcing the clip base 20 may be formed on the surface of the clip base 20 facing the vehicle interior. A plurality of base ribs 27 are formed, and each is connected to a peripheral rib 11 formed on the peripheral edge 101 of the cover member 10. The peripheral ribs 11 are ribs for reinforcing the cover member 10. The base ribs 27 extending from the peripheral rib 11 are formed to span from the recess 21 to the tips 222, 232 of the guide walls 22, 23, respectively.

[0040] According to the above-mentioned configuration of the clip base 20 of the door hole cover 1, the protruding portion 25 is not formed on the guide wall 22 of the pair of guide walls 22, 23. Therefore, by using a tool for removing the door hole cover 1 from the door inner panel D1 from the guide wall 22 side where the protruding portion 25 is not formed, the protruding portion 25 and the tool do not interfere with each other, and the door hole cover 1 can be removed from the door inner panel D1. This improves the efficiency of the removal work of removing the door hole cover 1 from the door inner panel D1. The removal work of the door hole cover 1 is performed, for example, when repairing or inspecting a window regulator in the front door D, or replacing or inspecting a wire harness (which may also be called a cable) connected to a speaker or the like.

[0041] Furthermore, according to the configuration in which the protrusion 25 is formed on the guide wall 23, the clip 30 comes into contact with at least a part of the guide wall 22 protruding in a direction narrowing the space 24 formed between the pair of guide walls 22, 23, and the protrusion 25 formed on the guide wall 23 comes into contact with the clip 30, thereby restricting the movement of the clip 30 toward the outside of the recess 21. This makes it possible to more reliably prevent the clip 30 from falling off the recess 21.

[0042] Moreover, the protrusion 25 is formed on the surface of the guide wall 23 facing the vehicle exterior. Therefore, a reinforcing portion such as a base rib 27 for reinforcing the guide wall 23 of the clip base 20 can be formed on the surface of the guide wall 23 facing the vehicle interior. This allows for flexibility in the shape of the guide wall 23 facing the vehicle interior.

[0043] The above-mentioned formation manner of the guide wall 22 and the guide wall 23 is merely an example. For example, at least one of the tip 222 of the guide wall 22 and the tip 232 of the guide wall 23 may have an inclined surface formed thereon to facilitate insertion of the clip 30 into the space 24. More specifically, the inclined surface formed on at least one of the tip 222 and the tip 232 inclines in a direction narrowing the space 24 from the tip 222 and / or the tip 232 side toward the recess 21. That is, the distance between the tip 222 and the tip 232 in the facing direction X may be increased.

[0044] Moreover, the above-described manner of forming the protruding portion 25 is merely one example. The protruding portion 25 is not limited to the configuration in which it is formed on the surface of the guide wall 23 on the vehicle exterior side, as in the present embodiment. For example, the protruding portion 25 may protrude from the surface of the guide wall 23 on the vehicle interior side toward the vehicle interior side. In this case, the protruding portion 25 restricts the movement of the clip 30 by abutting against the second flange portion 34 of the clip 30. Moreover, the protruding portion 25 may be formed so as to protrude in the vehicle interior / exterior direction from the surface of the guide wall 22 on the vehicle interior side or the vehicle exterior side, instead of the guide wall 23.

[0045] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
