[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-172934 [Patent Document 2] Utility Model Registration No. 2578735 Summary of the Invention [Problem to be solved by the invention]

[0006] When a fastening flange is formed in the opening of the inner panel, the opening shape becomes complex, and there is a risk that the worker's sleeve or other parts may get caught on the flange when reaching into the opening to access the outer panel.

[0007] Therefore, this specification discloses a structure for attaching a component to an inner panel of a vehicle door, which simplifies the shape of the opening in the inner panel and provides sufficient fastening strength. [Means for solving the problem]

[0008] This specification discloses a component mounting structure for an inner panel of a vehicle door. An opening is formed in the inner panel. The opening is closed by a base plate from the passenger compartment side. An opening peripheral portion of the inner panel surrounding the opening faces a plate peripheral portion of the base plate. A locking member is provided on the base plate. The locking member is provided closer to the center of the base plate than the plate peripheral portion. The locking member includes a rotating shaft portion, a claw portion, and an arm portion. The rotating shaft portion penetrates the base plate in the thickness direction. The claw portion and the arm portion protrude radially from the rotating shaft portion. The claw portion and the arm portion are provided on the rotating shaft portion, sandwiching the base plate therebetween. The claw portion is rotatable between an engaged state and a released state. In the engaged state, the claw portion clamps the opening peripheral portion of the inner panel together with the plate peripheral portion. In the released state, the claw portion is separated from the opening peripheral portion. The base plate includes a tapered portion. The tapered portion has an inclined surface. The inclined surface is formed along the rotation path of the arm portion and abuts against the arm portion 52. Furthermore, the inclined surface protrudes toward the passenger compartment.

[0009] According to the above configuration, the rotation of the claw allows the inner panel to be detached from the base plate. This eliminates the need for a flange in the opening of the inner panel. Furthermore, as the arm rotates along the inclined surface, the rotation shaft and the claw are pulled up toward the vehicle interior. Therefore, the claw and the base plate firmly grip the periphery of the opening of the inner panel.

[0010] In the above configuration, the tapered portion may be formed with a seating surface recessed from the inclined surface.

[0011] According to the above configuration, the arm portion is seated on the seating surface, thereby making it possible to suppress loosening of the fastening force.

[0012] In the above-described configuration, a protrusion may be formed on the periphery of the opening of the inner panel, the apex of which protrudes further outward than the edge of the opening.

[0013] The edge of the opening of the inner panel may have burrs. By having the protrusions abut against the claws while avoiding the edge of the opening, it is possible to prevent the claws from getting caught on the burrs during rotation.

[0014] In the above configuration, the claw portion may be capable of contacting an outer surface of the periphery of the opening of the inner panel on the vehicle exterior side. In this case, the claw portion has a tapered surface that becomes increasingly separated from the outer surface as it approaches the tip of the claw portion.

[0015] According to the above configuration, the tapered surface of the claw portion can prevent burrs from forming on the edge of the opening. [Effects of the Invention]

[0016] According to the structure for mounting a component to an inner panel of a vehicle door disclosed in this specification, the shape of the opening in the inner panel is simplified and sufficient fastening force is provided. [Brief explanation of the drawings]

[0018] 1 to 8 show an example of a vehicle underside structure according to this embodiment. In FIGS. 1 to 8, the front-to-rear direction of the vehicle is indicated by the FR axis. The vehicle width direction is indicated by the RW axis. The vertical direction is indicated by the UP axis. The FR axis has the forward direction as its positive direction. The RW axis has the rightward direction as its positive direction. The UP axis has the height direction as its positive direction.

[0019] 1 to 8 illustrate the structure of a right-side front door of a vehicle. Therefore, the positive side along the RW axis is the outside of the vehicle. The negative side along the RW axis is the inside of the vehicle.

[0020] 1. Overall structure 1 is an exploded perspective view of a vehicle door. The vehicle door is shown as a right-side front door. The front door includes an outer panel 10, an inner panel 30, and a trim board 20.

[0021] The outer panel 10 is the outer panel of the vehicle door. For example, the outer panel 10 is made of an aluminum panel. The outer surface of the outer panel is part of the vehicle's design. A sash 12 is provided on the upper part of the outer panel 10. Reinforcing members are attached to the inner surface of the outer panel 10. The reinforcing members include an impact beam 14 and a reinforcement 16.

[0022] The inner panel 30 is an inner panel of the vehicle door. For example, the inner panel 30 is made of an aluminum panel. Devices for the vehicle door are attached to the inner panel 30. For example, as illustrated in FIG. 1 , a speaker 36 is attached to the inner panel 30. As will be described later, the speaker 36 is attached to the inner panel 30 via a base plate 40.

[0023] The trim board 20 is attached to the inner surface 30A of the inner panel 30. The trim board 20 contains a resin material such as ABS resin. The trim board 20 forms part of the interior design of the vehicle. An inside handle 22 and a speaker mesh 24 are provided on the trim board 20.

[0024] 2. Inner panel 2 and 3, an opening 31 is formed in the inner panel 30. The opening 31 is also called a service hole. Referring to FIG. 3, the opening 31 allows access to the inner surface of the outer panel 10. Furthermore, devices such as a speaker 36 can be attached to the inner panel 30 via a base plate 40.

[0025] The opening 31 is formed by, for example, press working, and therefore, burrs (not shown) may be formed on the opening edge 32.

[0026] The opening 31 is, for example, substantially rectangular. That is, the opening 31 has four sides and rounded portions connecting these sides. For example, a service hole may be provided with a flange that extends from the edge of the opening to the center of the opening. However, in the inner panel 30 according to this embodiment, such a flange does not have to be formed on the opening 31.

[0027] An opening peripheral portion 35 is set to surround the opening 31. The opening peripheral portion 35 refers to a band-shaped region surrounding the opening 31. The opening peripheral portion 35 includes a sealing surface 34 and a protruding portion 33. The sealing surface 34 is a surface that abuts against the seal strip 46 of the base plate 40. The protruding portion 33 is formed closer to the opening edge 32 than the sealing surface 34. For example, the protruding portion 33 is formed in an annular shape. In other words, the protruding portion 33 surrounds the opening 31. By surrounding the periphery of the opening 31 with the protruding portion 33, the surface rigidity around the opening 31 is improved.

[0028] 7A illustrates a cross-sectional view of the inner panel 30 and the base plate 40. As shown by the coordinate axes in FIG. 7A, the bottom of the paper in this drawing indicates the vehicle exterior. As shown in FIG. 7A, the apex 33A of the protrusion 33 protrudes further toward the vehicle exterior than the opening edge 32. For example, the opening edge 32 is located below the apex 33A of the protrusion 33.

[0029] As a result of the apex 33A of the protrusion 33 protruding further toward the vehicle exterior (lower side of the drawing) than the opening edge 32, the claw 54 of the locking member 50 passes over the opening edge 32 and comes into contact with the apex 33A of the protrusion 33. In other words, the claw 54 can rotate from the engaged state (see FIG. 6) to the released state (see FIG. 5) without coming into contact with the opening edge 32.

[0030] 3. Base plate 3, the base plate 40 closes the opening 31 from the passenger compartment side. The base plate 40 is also called a service cover. The base plate 40 is made of the same panel material as the inner panel 30. For example, the base plate 40 is made of an aluminum panel.

[0031] An electrical device such as a speaker 36 is attached to the base plate 40. The base plate 40 and the speaker 36 are collectively called a speaker module. When repairing the speaker 36, for example, the base plate 40 can be removed from the inner panel 30, allowing work to be done in a small space.

[0032] The base plate 40 and the opening 31 may have similar shapes. For example, the base plate 40 is slightly larger than the opening 31.

[0033] A plate peripheral portion 45 is set on the base plate 40. For example, the plate peripheral portion 45 is an annular, band-shaped region. The plate peripheral portion 45 refers to the region where the seal strip 46 (see FIG. 4) is arranged. In other words, the installation surface of the seal strip 46 is the plate peripheral portion 45. FIGS. 5 and 6 illustrate a cross section of the locking member 50A in FIG. 2. FIGS. 5 and 6 illustrate perspective views at an angle where the vehicle width axis (RW axis) is oriented downward on the paper. As illustrated in FIG. 5, the plate peripheral portion 45 and the opening peripheral portion 35 of the inner panel 30 face each other along the vehicle width direction.

[0034] The recess 41 is formed closer to the center of the base plate 40 than the plate peripheral edge 45. Here, a part of the recess 41 may overlap with the plate peripheral edge 45. At least the center of the recess 41 is located closer to the center of the base plate 40 than the plate peripheral edge 45.

[0035] A plurality of recesses 41 are formed along the plate peripheral edge 45. For example, referring to FIG.

[0036] Recess 41 is a circular depression in front view. Locking member 50 is installed in recess 41. Also, referring to Figure 7B, an insertion hole 47 is drilled in the center of recess 41. Rotation shaft 53 of locking member 50 is inserted into insertion hole 47.

[0037] 5 and 6, a tapered portion 42 is formed on an inner surface 40A of the recess 41. The inner surface 40A refers to the surface of the base plate 40 facing the cabin. The outer surface 40B refers to the surface of the base plate 40 facing the exterior of the vehicle.

[0038] The tapered portion 42 extends in an arc shape within the recess 41. For example, the arc angle of the tapered portion 42 is equal to or greater than 40° and equal to or less than 100°. Two tapered portions 42 are formed in one recess 41.

[0039] An inclined surface 42A is formed on the tapered portion 42. The inclined surface 42A is the contact surface (sliding surface) of the arm portion 52. The inclined surface 42A protrudes toward the vehicle interior. In other words, the inclined surface 42A protrudes away from the inner panel 30. The inclined surface 42A extends along the rotation trajectory of the arm portion 52 of the locking member 50. In other words, the arm portion 52 moves on the inclined surface 42A.

[0040] Furthermore, a seating surface 42B is formed on the tapered portion 42. The seating surface 42B is recessed relative to the inclined surface 42A. The depth of the recess is, for example, 5% to 50% of the thickness of the arm portion 52. The seating surface 42B is provided at the highest portion (end point) of the inclined surface 42A.

[0041] Fig. 5 illustrates the locking member 50 in the released state. Fig. 6 illustrates the locking member 50 in the engaged state. As will be described later, in the released state, the arm portion 52 is separated from the inclined surface 42A. In addition, in the engaged state, the arm portion 52 is seated on the seating surface 42B. That is, in the engaged state, the arm portion 52 is seated on the tapered portion 42, thereby preventing loosening of the fastening by the locking member 50.

[0042] 3 and 4, rainwater or the like may infiltrate the inner surface of the outer panel 10. Therefore, sealing performance is required to close the opening 31. Therefore, a seal strip 46 is arranged on the outer surface 40B of the base plate 40. The seal strip 46 is made of an elastic material such as rubber. The seal strip 46 is an annular member and is arranged on the periphery of the base plate 40. As described above, the area of ​​the base plate 40 where the seal strip 46 is arranged becomes the plate periphery 45.

[0043] 7 and 8, the sealing strip 46 is crushed by the base plate 40 and the inner panel 30 during the process of fastening the locking member 50. This ensures sealing at the opening 31 (see FIG. 3).

[0044] 4. Locking member 5 to 8 show an example of a locking member 50. The locking member 50 includes a head 51, an arm portion 52, a rotating shaft portion 53, a claw portion 54, and a seal lip 55. The locking member 50 is made of, for example, a resin material. The locking member 50 is disposed closer to the center of the base plate 40 than the plate peripheral edge portion 45.

[0045] The rotating shaft 53 penetrates the base plate 40 in the thickness direction. The rotating shaft 53 is inserted into the insertion hole 47 (see FIG. 7B) of the recess 41. The rotating shaft 53 is, for example, a hollow cylindrical portion. The upper end opening of the rotating shaft 53 is closed by the head 51.

[0046] 5 and 6, the rotating shaft portion 53 is rotatable around the rotation axis C1. Furthermore, the diameter of the insertion hole 47 (see FIG. 7B) exceeds the diameter of the rotating shaft portion 53. That is, the rotating shaft portion 53 is capable of advancing and retreating within the insertion hole 47 along the rotation axis C1.

[0047] A seal lip 55 is provided on the rotary shaft 53 to seal the gap between the rotary shaft 53 and the insertion hole 47. The seal lip 55 has an annular shape. The tip portion (radially outer portion) of the seal lip 55 abuts against the recess 41, thereby suppressing leakage of liquid from the inner panel 30 to the insertion hole 47.

[0048] The rotating shaft portion 53 is provided with an arm portion 52 and a claw portion 54. The arm portion 52 and the claw portion 54 protrude radially from the rotating shaft portion 53. For example, when the locking member 50 is viewed along the rotation axis C1, the arm portion 52 and the claw portion 54 are arranged offset from each other. For example, a pair of arm portions 52, 52 are arranged at 180° with the rotating shaft portion 53 as the center. The claw portion 54 is provided between the pair of arm portions 52, 52.

[0049] Further, a claw portion 54 is formed at the lower end of the rotation shaft portion 53 along the rotation axis C1. Further, an arm portion 52 is formed at the upper end of the rotation shaft portion 53. As illustrated in Fig. 5, the arm portion 52 and the claw portion 54 are disposed on the rotation shaft portion 53 with the base plate 40 sandwiched therebetween.

[0050] 6, the arm portion 52 extends in the radial direction of the rotating shaft portion 53. The arm portion 52 may be bent as shown in Fig. 6. Alternatively, the arm portion 52 may extend linearly along the radial direction of the rotating shaft portion 53.

[0051] Furthermore, the circumferential dimension of the arm portion 52, in other words, the dimension along the rotation direction, is less than the same dimension of the seating surface 42B of the tapered portion 42. By setting such dimensions, the arm portion 52 can fit into the seating surface 42B.

[0052] The claw portion 54 protrudes radially from the lower end of the rotary shaft portion 53. As illustrated in Figures 5, 7, and 8, the lower end of the claw portion 54 may be open. For example, the claw portion 54 has a box shape including an upper wall and a pair of side walls.

[0053] When the rotary shaft portion 53 rotates around the rotary axis C1, the claw portion 54 also rotates. The claw portion 54 is rotatable between an engaged state (see FIG. 6) and a released state (see FIG. 5). In the engaged state, the claw portion 54, together with the plate peripheral portion 45, clamps the opening peripheral portion 35. In the released state, the claw portion 54 moves away from the opening peripheral portion 35.

[0054] In the engaged state (see FIG. 6), the claw portion 54 can come into contact with the outer surface 30B of the inner panel 30. As described above, there is a risk of burrs being formed on the opening edge 32 of the inner panel 30. If the claw portion 54 gets caught on the burrs, it may become difficult for the claw portion 54 to rotate.

[0055] Therefore, a tapered surface 54A is formed on the claw portion 54. Furthermore, the above-mentioned protrusion 33 is formed on the inner panel 30. The tapered surface 54A becomes increasingly separated from the outer surface 30B of the inner panel 30 as it approaches the tip of the claw portion 54. The tip of the claw portion 54 refers to the end of the upper wall of the claw portion 54 that is farthest from the rotation shaft portion 53.

[0056] 5 and 6, head 51 is provided with a bolt head structure. A tool such as an impact driver is inserted into head 51. By avoiding operations such as turning arm 52 with fingers, damage to arm 52 is avoided. Furthermore, torque management using an impact driver or the like controls the amount of compression of seal strip 46. In other words, the sealing performance of base plate 40 is controlled through torque management.

[0057] 5. Installation process 5-8 illustrate the installation process of the base plate 40 (and speaker 36). First, in the initial state, in the released state as shown in FIG. 5, the base plate 40 is placed over the opening 31 (see FIG. 3). In FIG. 5, the bottom of the page indicates the width direction of the vehicle (toward the outside of the vehicle). The direction of gravity is the left side of the page. As illustrated in FIG. 5, in the released state, the side of the claw portion 54 is hooked onto the opening edge 32, creating a temporary fastening state.

[0058] 7 illustrates an initial state in which the rotation shaft portion 53 has been rotated from the released state toward the engaged state. Because the arm portion 52 (see FIG. 5) moves in a relatively low region of the inclined surface 42A, the amount of crushing of the seal strip 46 (see FIG. 7) is slight. The seal strip 46 acts as a spacer, separating the claw portion 54 and the protrusion 33 along the rotation axis C1.

[0059] 7A and 7B, as the claw portion 54 rotates, the tip of the claw portion 54 slips directly under the protrusion 33. Because the tapered surface 54A is formed, the claw portion 54 is prevented from contacting the opening edge 32.

[0060] Further, as arm portion 52 advances along inclined surface 42A, rotating shaft portion 53 and claw portion 54 are pulled up toward base plate 40. Referring to Figures 8A and 8B, claw portion 54 that has slipped directly under protrusion 33 comes into contact with apex 33A of protrusion 33. As shown in the figures, opening edge 32 and rotating shaft portion 53 are spaced apart in the radial direction, so contact between opening edge 32 and claw portion 54 and rotating shaft portion 53 is avoided.

[0061] As the rotary shaft portion 53 and the claw portion 54 are pulled up, the seal strip 46 is crushed, thereby ensuring the sealing of the opening 31 (see FIG. 3). [Explanation of symbols]
