Description

Anti-misassembly structure for vehicle

[0001] The present invention relates to an improved anti-misassembly structure for a vehicle.

[0002] Some components attached to a vehicle are composed of a plurality of members assembled with each other. A technique related to the assembled components is disclosed in Patent Document 1.

[0003] Patent Document 1 discloses an opening / closing body that can open and close a fuel filler opening of a vehicle. This opening / closing body includes a lid having a shape along the edge of the fuel filler opening and a base material that supports the lid from the back side. The lid and the base material are assembled by sliding them with each other.

[0004] Japanese Patent Application Laid-Open No. 2013 - 123930

[0005] When manufacturing two types of opening / closing bodies having different outer shapes and sizes, a sliding assembly structure may be adopted as in the opening / closing body disclosed in Patent Document 1. Since the two types of opening / closing bodies have a common assembly structure, the manufacturing cost can be suppressed, but there is a risk of assembling incorrect members with each other. It is desirable to be able to prevent incorrect assembly with a configuration as simple as possible.

[0006] An object of the present invention is to provide an anti-misassembly structure for a vehicle with a simple configuration.

[0007] In the present disclosure, there are provided a first member and a second member that can be assembled to the first member, and the guide portion of the first member guides the guided portion of the second member, whereby the second member can be assembled to the first member. The guided portion of the second member is set to contact the third member when the second member is attempted to be assembled to the third member so that the second member cannot be incorrectly assembled to the third member, and an anti-misassembly structure for a vehicle is provided.

[0008] The present invention can provide an anti-misassembly structure for a vehicle with a simple configuration.

[0010] <Examples> Examples will be described based on the attached figures. Note that the examples described here are not intended to particularly limit the present invention. In the figures, Le indicates left, Ri indicates right, Up indicates up, and Dn indicates down.

[0011] Refer to Figure 1. A vehicle exterior member 11 (for example, a front grille) that can be attached to the body of an electric vehicle has a first opening 12 for a normal charging port and a second opening 13 for a fast charging port. The first opening 12 can be opened and closed by a swingable first opening / closing body 15, and the second opening 13 can be opened and closed by a swingable second opening / closing body 16. Note that the normal charging port and fast charging port may be reversed, or they may be fuel ports. The application is not limited.

[0012] (First opening / closing body 15) Refer to Figures 2A to 2C. The first opening / closing body 15 comprises a substantially rectangular plate-shaped lid 40 (second member) formed to match the shape of the first opening 12, and a base material 20 (first member) capable of supporting the lid 40. The lid 40 is assembled to the base material 20. The base material 20 has a bottom surface 21 that faces the back surface 41 of the lid 40 (the side opposite to the design surface 42) when the lid 40 and the base material 20 are assembled, and a peripheral wall portion 22 that extends from the periphery of the bottom surface 21 toward the back surface 41.

[0013] (Matching structure) In order to maintain the assembly of the lid 40 and the base material 20, a fitting structure is provided in the internal space surrounded by the back surface 41 of the lid 40, the bottom surface 21 of the base material 20, and the peripheral wall portion 22. Specifically, the base material 20 is provided with a plurality of fitting portions 23, 29, 32, and 34. The lid 40 is provided with a plurality of fitted portions 44, 49, 54, and 55 that can be fitted into the plurality of fitting portions 23, 29, 32, and 34.

[0014] (Assembly Method) The assembly of the lid 40 to the base material 20 will now be described. Refer to Figures 3A and 3B. First, the back surface 41 of the lid 40 is superimposed on the tip 22a of the peripheral wall portion 22 of the base material 20. Refer to Figure 4B. Next, when the back surface 41 of the lid 40 is slid in the assembly direction A relative to the tip 22a of the peripheral wall portion 22 of the base material 20, the fitting portions 44, 49, 54, 55 of the lid 40 fit into the fitting portions 23, 29, 32, 34 of the base material 20, completing the assembly and obtaining the first opening / closing body 15.

[0015] (Direction) Refer to Figures 2A to 2C. When viewed from the direction opposite to the back surface 41 of the lid 40, the direction along the assembly direction A is defined as the length direction L, and the direction perpendicular to the length direction L is defined as the width direction W. The direction opposite to the assembly direction A is defined as the removal direction R. Note that the length direction L is also the longitudinal direction of the lid 40 and the base material 20, and the width direction W is also the short direction of the lid 40 and the base material 20.

[0016] (First fitting portion 23) Refer to Figures 2C and 3C. The bottom surface 21 of the base material 20 is provided with a rib-shaped first support rib 27 that supports the first fitting portion 23. The first support rib 27 extends in the width direction W. The first fitting portion 23 has a base portion 24 supported by the first support rib 27 and the bottom surface 21, and a fitting body portion 25 that protrudes from the base portion 24 in the removal direction R.

[0017] (First fitting portion 44) Refer to Figures 2B and 4E. The first fitting portion 44 is box-shaped and has an opening that opens toward the assembly direction A. The first fitting portion 44 is along the back surface 41 and has a plate-shaped fitting body portion 45 that can be fitted into the first fitting portion 23, a pair of side wall portions 46, 46 that are provided from both ends of the fitting body portion 45 on the width direction W side to the back surface 41, and a back wall portion 47 that is provided from the end of the fitting body portion 45 on the removal direction R side to the back surface 41.

[0018] The pair of side walls 46, 46 and the back wall 47 can also be said to be parts that support the fitted body portion 45, and either one alone may be sufficient. Once assembly is complete, the fitted body portion 25 of the base material 20 fits inside the box-shaped first fitted portion 44. The fitted body portion 25 of the base material 20 and the fitted body portion 45 of the lid 40 overlap each other in the thickness direction of the lid 40, pressing against each other.

[0019] Furthermore, the engagement length, which is the length by which the fitting body portion 25 and the fitted body portion 45 fit together, is greater than that of other fitting structures (second fitting portion 32 and second fitted portion 54, third fitting portion 34 and third fitted portion 55).

[0020] (Guide structure) Refer to Figures 2B, 2C, 4B, and 4D. The internal space of the first opening / closing body 15 is provided with a guide structure that guides the assembly of the lid 40 to the base material 20. The base material 20 is provided with a guide portion 31. The lid 40 is provided with a guided portion 51 that is guided by the guide portion 31.

[0021] (Guide portion 31) The guide portion 31 is a rib provided on the bottom surface 21 of the base material 20, and extends from one end in the width direction W of the support rib in the removal direction R. The guide portion 31 has a planar guide body portion 31a facing inward in the width direction W. Note that the shape of the guide portion 31 is not limited to a rib as long as it has a planar guide body portion 31a.

[0022] (Guided portion 51) The guided portion 51 is an L-shaped rib provided on the back surface 41 of the lid 40. The guided portion 51 has a first rib 52 extending along the length direction L, and a second rib 53 extending inward in the width direction W from the end of the first rib 52 on the assembly direction A side.

[0023] The first rib 52 faces outward in the width direction W and has a planar guided body portion 52a that can contact and be guided by the guide body portion 31a. The guide portion 31 and the guided body portion 51 can suppress rattle in the width direction W. When the lid 40 is placed on the base material 20, the guided body portion 52a and the guide body portion 31a are separated but may be in contact.

[0024] Furthermore, as long as it has a planar guided body portion 52a, the shape of the guided portion 51 is not limited to a rib. The guided portion 51 may consist only of the first rib 52.

[0025] The second rib 53 is connected to the side wall portion 46 of the first fitting portion 44, but it may be separated from it.

[0026] (Second fitting portion 32) Refer to Figures 2B and 2C. The base material 20 is provided with two second fitting portions 32, 32 located on the assembly direction A side than the first fitting portion 23. Each second fitting portion 32 is supported by a rib-shaped second support rib 33 that extends inward in the width direction W from the peripheral wall portion 22.

[0027] (Second fitting portion 54) The back surface 41 of the lid 40 is provided with second fitting portions 54, 54 that can be fitted into the second fitting portion 32. Refer to Figures 2B and 3C. The second fitting portions 54, 54 are symmetrical with respect to the center line C2 (see Figure 3C). The center line C2 is a line that passes through the center of the width direction W of the first fitting portion 44 and is along the length direction L, and is also the center line of the width direction W of the lid 40.

[0028] (Third fitting portion 34) The base material 20 is provided with two third fitting portions 34, 34 located on the assembly direction A side than the second fitting portions 32, 32. Each of the third fitting portions 34, 34 is supported by the peripheral wall portion 22.

[0029] (Third fitting portion 55) The back surface 41 of the lid 40 is provided with third fitting portions 55, 55 that can be fitted into the third fitting portions 34, 34. The third fitting portions 55, 55 are symmetrical with respect to C2.

[0030] The structure of the second fitting portion 32 and the second fitted portion 54, and the structure of the third fitting portion 34 and the third fitted portion 55 are the same as those of the first fitting portion 23 and the first fitted portion 44. The size of the second fitting portion 32 and the second fitted portion 54, and the size of the third fitting portion 34 and the third fitted portion 55 are smaller than those of the first fitting portion 23 and the first fitted portion 44. The size, number, and structure of each fitting portion and fitted portion are arbitrary.

[0031] (Fourth fitting portion 29) "Fitting" refers to a mechanism that maintains the assembly between the lid 40 and the base material 20, not limited to the above configuration. The bottom surface 21 of the base material 20 has a fourth fitting portion 29. The fourth fitting portion 29 is a rib extending in the width direction W.

[0032] (Fourth fitting portion 49) The back surface 41 of the lid 40 is located on the assembly direction A side than the first fitting portion 44 and has a fourth fitting portion 49 that can be fitted into the fourth fitting portion 29. The fourth fitting portion 49 has a protruding portion 49a that protrudes toward the bottom surface 21 of the base material 20. When the lid 40 is slid relative to the base material 20 and the tip of the rib of the fourth fitting portion 29 goes over the tip of the protruding portion 49a, the assembly is completed.

[0033] (Second opening / closing body 16) Refer to Figures 5A to 5C. The second opening / closing body 16 comprises a substantially rectangular plate-shaped lid 80 (third member) formed to match the shape of the second opening 13, and a base material 60 (fourth member) capable of supporting the lid 80. The lid 80 is assembled to the base material 60. The base material 60 has a bottom surface 61 that faces the back surface 81 of the lid 80 (the side opposite to the design surface 82) when the lid 80 and the base material 60 are assembled, and a peripheral wall portion 62 that extends from the periphery of the bottom surface 61 toward the back surface 81.

[0034] (Matching structure) In order to maintain the assembly of the lid 80 and the base material 60, a fitting structure is provided in the internal space surrounded by the back surface 81 of the lid 80, the bottom surface 61 of the base material 60, and the peripheral wall portion 62. Specifically, the base material 60 is provided with a plurality of fitting portions 63, 69, 72, and 74. The lid 80 is provided with a plurality of fitted portions 84, 89, 94, and 95 that can be fitted into the plurality of fitting portions 63, 69, 72, and 74.

[0035] (Assembly Method) Similar to the first opening / closing body 15, the back surface 81 of the lid 80 is placed on top of the tip 62a of the peripheral wall portion 62 of the base material 60. Then, the back surface 81 of the lid 80 is slid in the assembly direction A relative to the tip 62a of the peripheral wall portion 62 of the base material 60. The fitting portions 84, 89, 94, and 95 of the lid 80 fit into the fitting portions 63, 69, 72, and 74 of the base material 60, thereby obtaining the second opening / closing body 16.

[0036] (First fitting portion 63) Refer to Figures 5C and 7C. The bottom surface 61 of the base material 60 is provided with a rib-shaped first support rib 67 that supports the first fitting portion 63. The first support rib 67 extends in the width direction W. The first fitting portion 63 has a base portion 64 supported by the first support rib 67 and the bottom surface 61, and a fitting body portion 65 that protrudes from the base portion 64 in the removal direction R.

[0037] (First Fitting Part 84) Refer to Figure 5B. The first fitting part 84 is box-shaped and has an opening that faces the assembly direction A. The first fitting part 84 is along the back surface 81 and has a plate-shaped fitting body part 85 that can be fitted into the first fitting part 63, a pair of side wall parts 86, 86 that are provided from both ends of the fitting body part 85 on the width direction W side to the back surface 81, and a back wall part 87 that is provided from the end of the fitting body part 85 on the removal direction R side to the back surface 81. The pair of side wall parts 86, 86 and the back wall part 87 can also be said to be parts that support the fitting body part 85, and either one or only may be present. The way in which the first fitting part 63 and the first fitting part 84 are fitted together is the same as the way in which the first fitting part 23 and the first fitting part 44 are fitted together as shown in Figure 4E.

[0038] Once the assembly is complete, the fitting body portion 65 of the base material 60 and the fitted body portion 85 of the lid 80 overlap each other in the thickness direction of the lid 80, pressing against each other.

[0039] Furthermore, the engagement length, which is the length at which the fitting body portion 65 and the fitted body portion 85 engage with each other, is greater than that of other fitting structures (second fitting portion 72 and second fitted portion 94, third fitting portion 74 and third fitted portion 95).

[0040] (Guide structure) Refer to Figures 5B and 5C. The internal space of the second opening / closing body 16 is provided with a guide structure that guides the assembly of the lid 80 to the base material 60. The base material 60 is provided with a guide portion 71. The lid 80 is provided with a guided portion 91 that is guided by the guide portion 71.

[0041] (Guide section 71) Refer to Figure 7C. The guide section 71 is a rib provided on the bottom surface 61 of the base material 60, and extends from one end in the width direction W of the first support rib 67 in the removal direction R. The guide section 71 has a planar guide body portion 71a facing inward in the width direction W. Note that the shape of the guide section 71 is not limited to a rib as long as it has a planar guide body portion 71a.

[0042] (Guided Portion 91) Refer to FIG. 5B. The guided portion 91 is an L-shaped rib provided on the back surface 81 of the lid 80. The guided portion 91 has a first rib 92 extending along the length direction L, and a second rib 93 extending from the end portion on the assembly direction A side of the first rib 92 inward in the width direction W.

[0043] Refer to FIG. 6. The first rib 92 faces the outside in the width direction W and has a planar guided main body portion 92a that can contact and be guided by the guide main body portion 71a. The guide portion 71 and the guided portion 91 can suppress play in the width direction W. When the lid 80 is overlapped with the base material 60, the guided main body portion 92a and the guide main body portion 71a are separated but may contact each other.

[0044] Note that as long as it has a planar guided main body portion 92a, the shape of the guided portion 91 is not limited to a rib. The guided portion 91 may be only the first rib 92.

[0045] The second rib 93 is continuous with the side wall portion 86 of the first fitting portion 84, but may be separated.

[0046] (Second Fitting Portion 72) Refer to FIGS. 5B and 5C. On the base material 60, two second fitting portions 72, 72 are provided, which are located on the assembly direction A side with respect to the first fitting portion 63. Each second fitting portion 72 is supported by a rib-shaped second support rib 73 extending inward in the width direction W from the peripheral wall portion 62.

[0047] (Second Fitted Portion 94) On the back surface 81 of the lid 80, second fitted portions 94, 94 that can be fitted to the second fitting portion 72 are provided. Refer to FIG. 7C. The second fitted portions 94, 94 are symmetric about the center line C4. The center line C4 passes through the center in the width direction W of the first fitting portion 84 and is a line along the length direction L, and is also the center line in the width direction W of the lid 80.

[0048] (Third Fitting Portion 74) On the base material 60, two third fitting portions 74, 74 are provided, which are located on the assembly direction A side with respect to the second fitting portions 72, 72. Each third fitting portion 74, 74 is supported by the peripheral wall portion 62.

[0049] (Third fitting portion 95) The back surface 81 of the lid 80 is provided with third fitting portions 95, 95 that can be fitted into the third fitting portions 74, 74. The third fitting portions 95, 95 are symmetrical with respect to the center line C4.

[0050] The structure of the second fitting portion 72 and the second fitted portion 94, and the structure of the third fitting portion 74 and the third fitted portion 95 are the same as those of the first fitting portion 63 and the first fitted portion 84. The size of the second fitting portion 72 and the second fitted portion 94, and the size of the third fitting portion 74 and the third fitted portion 95 are smaller than those of the first fitting portion 63 and the first fitted portion 84.

[0051] (Fourth fitting portion 69) The bottom surface 61 of the base material 60 has a fourth fitting portion 69. The fourth fitting portion 69 is a rib that extends in the width direction W.

[0052] (Fourth fitting portion 89) The back surface 81 of the lid 80 is located on the assembly direction A side than the first fitting portion 84 and has a fourth fitting portion 89 that can be fitted into the fourth fitting portion 69. The fourth fitting portion 89 has a protruding portion 89a that protrudes toward the bottom surface 61 of the base material 60. When the lid 80 is slid relative to the base material 60 and the tip of the rib of the fourth fitting portion 69 goes over the tip of the protruding portion 89a, the assembly is completed.

[0053] (Obstruction part 70) Refer to Figure 6. Multiple fitting parts 44, 49, 54, 55 of the lid 40 can be fitted onto fitting parts 63, 69, 72, 74 of the base material 60. To prevent the lid 40 from being mistakenly assembled onto the base material 60, the lid 40 and the base material 60 are fitted with an assembly prevention structure 10.

[0054] Refer to Figure 7C. The bottom surface 61 of the base material 60 has an opposite-side rib 75 located on the opposite side of the guide portion 71, with the first fitting portion 63 as the center. The opposite-side rib 75 extends from the end of the support rib 67 toward the removal direction R.

[0055] The opposite rib 75 and the guide portion 71 are symmetrical with respect to the center line C3. The center line C3 is a line that passes through the center in the width direction W of the first fitting portion 63 of the base material 60 and is along the length direction L, and is also the center line in the width direction W of the base material 60. In other words, since the first fitting portion 63 is located at the center in the width direction W of the base material 60, the design freedom of the surrounding area is increased. The design freedom of the area around the first fitted portion 84 that fits into the first fitting portion 63 is also increased.

[0056] The bottom surface 61 of the base material 60 has a tip rib 76 extending inward in the width direction from the tip of the opposite rib 75, an intermediate rib 77 extending inward in the width direction from the middle of the opposite rib 75, a first inner rib 78 provided along the length direction L from the intermediate rib 77 to the tip of the tip rib 76, and a second inner rib 79 provided along the length direction L from the intermediate rib 77 to the support rib 67.

[0057] The intermediate rib 77 is located on the side of the first fitting portion 63 that is closer to the removal direction than the tip of the first fitting portion 63. The second inner rib 79 is located inward in the width direction than the first inner rib 78, but it may be in the same position or outward in the width direction.

[0058] When the base material 60 and the lid 40 are placed together with the center lines C2 and C3 overlapping (the lid 40 is not misaligned in the width direction W relative to the base material 60), the guided portion 51 will contact one of the tip rib 76, intermediate rib 77, first inner rib 78, or second inner rib 79.

[0059] The tip rib 76, intermediate rib 77, first inner rib 78, and second inner rib 79 are obstruction parts 70 that come into contact with the guided portion 51 of the lid 40 when the base material 60 and the lid 40 are incorrectly assembled, thereby preventing assembly of the base material 60 and the second lid. The obstruction parts 70 are not limited to ribs; any configuration that can prevent the overlapping of the lid 40, base material 60, and lid 40 by coming into contact with the guided portion 51 of the lid 40 is acceptable.

[0060] In this embodiment, the guided portion 51 has a first rib 52 along the length direction L and a second rib 53 along the width direction W. The obstruction portion 70 has a first inner rib 78 and a second inner rib 79 along the length direction L, and a tip rib 76 and an intermediate rib 77 along the width direction W. Since both the guided portion 51 and the obstruction portion 70 have parts extending in orthogonal directions, they are prone to contact with each other.

[0061] Refer to Figures 6 and 7C. When the lid 80 is assembled to the base material 60 (correct assembly), the first inner rib 78 and the second inner rib 79 can contact the side wall portion 86 of the first fitting portion 84, thereby suppressing rattle in the width direction W of the lid 80.

[0062] (Obstacle section 30) Multiple fitting portions 84, 89, 94, and 95 of the lid 80 can be fitted onto fitting portions 23, 29, 32, and 34 of the base material 20. To prevent the lid 80 from being mistakenly assembled to the base material 20, the base material 20 and the lid 80 are also fitted with an assembly prevention structure 10.

[0063] Refer to Figure 3C. The bottom surface 21 of the base material 20 has an opposite-side rib 35 located on the opposite side of the guide portion 31, with the first fitting portion 23 as the center. The opposite-side rib 35 extends from the end of the first support rib 27 toward the removal direction R.

[0064] The opposite rib 35 and the guide portion 31 are symmetrical with respect to the center line C1. The center line C1 is a line that passes through the center in the width direction W of the first fitting portion 23 of the base material 20 and is along the length direction L, and is also the center line in the width direction W of the base material 20. In other words, since the first fitting portion 23 is located at the center in the width direction W of the base material 20, the design freedom of the surrounding area is increased. The design freedom of the area around the first fitted portion 44 that fits into the first fitting portion 23 is also increased.

[0065] The bottom surface 21 of the base material 20 has a tip rib 36 extending inward in the width direction W from the tip of the opposite rib 35, an intermediate rib 37 extending inward in the width direction W from the middle of the opposite rib 35, a first inner rib 38 provided along the length direction from the intermediate rib 37 to the tip of the tip rib 36, and a second inner rib 39 provided along the length direction from the intermediate rib 37 to the support rib 27.

[0066] The intermediate rib 37 is located on the side of the removal direction R from the tip of the first fitting portion 23. The second inner rib 39 is located inward in the width direction W from the first inner rib 38, but it may be in the same position or outward in the width direction.

[0067] Refer to Figures 3C and 5B. When the base material 20 and the lid 80 are placed together with the center lines C1 and C4 overlapping (the lid 80 is not misaligned with respect to the base material 20 in the width direction W), the guided portion 91 will be in contact with either the tip rib 36, the intermediate rib 37, the first inner rib 38, or the second inner rib 39.

[0068] The tip rib 36, intermediate rib 37, first inner rib 38, and second inner rib 39 are obstruction parts 30 that come into contact with the guided portion 91 of the lid 80 when the base material 20 and the lid 80 are incorrectly assembled, thereby preventing assembly of the base material 20 and the second lid. The obstruction parts 30 are not limited to ribs; any configuration is acceptable as long as it can prevent the overlapping of the base material 20 and the lid 80 by coming into contact with the second guided portion 91.

[0069] In this embodiment, the guided portion 91 has a first rib 92 along the length direction and a second rib 93 along the width direction. The obstruction portion 30 has a first inner rib 38 and a second inner rib 39 along the length direction, and a tip rib 36 and an intermediate rib 37 along the width direction W. Since both the guided portion 51 and the obstruction portion 70 have parts extending in orthogonal directions, they are prone to contact with each other.

[0070] Refer to Figures 3C and 6. When the lid 40 is assembled to the base material 20 (correct assembly), the first inner rib 38 and the second inner rib 39 can contact the side wall portion 46 of the first fitting portion 44, thereby suppressing rattling in the width direction of the lid 20.

[0071] (Symmetry) Refer to Figure 6. When the mating portions 44, 49, 54, 55 of lid 40 and the mating portions 84, 89, 94, 95 of lid 80 are placed opposite each other, the guided portion 51 of lid 40 and the guided portion 91 of lid 80 face each other. With this configuration, the molds for lids 40 and 80 can be shared by nesting the portions including the guided portions 51 and 91. Therefore, the number of molds can be reduced, and manufacturing can be done at a lower cost.

[0072] When the fitting portions 23, 29, 32, 34 of the base material 20 are placed opposite the fitting portions 63, 69, 72, 74 of the base material 60, the guide portion 31 of the base material 20 and the guide portion 71 of the base material 60 face each other, and the obstruction portion 30 of the base material 20 and the obstruction portion 70 of the base material 60 face each other. With this configuration, the molds for the base materials 20 and 60 can be shared by nesting the portions including the obstruction portions 30 and 70. Therefore, the number of molds can be reduced, and manufacturing can be done at a low cost.

[0073] (Effects of the embodiment) Refer to Figure 6. The first vehicle misassembly prevention structure 10 comprises a base material 20 (first member) and a lid 40 (second member) that can be assembled to the base material 20. The guide portion 31 of the base material 20 guides the guided portion 51 of the lid 40, so that the lid 40 can be assembled to the base material 20. The guided portion 51 of the lid 40 is set to come into contact with the base material 60 when attempting to assemble the lid 40 to the base material 60, so that the lid 40 is not mistakenly assembled to the base material 60 (third member).

[0074] The guided portion 51 of the lid 40 serves as a guide during correct assembly with the base material 20, and in the event of incorrect assembly with the base material 60, it contacts the base material 60 to prevent incorrect assembly. The guided portion 51 of the lid 40 serves two functions. A simple vehicle misassembly prevention structure 10 can be provided.

[0075] Secondly, in the first vehicle misassembly prevention structure 10, the guide portion 71 of the base material 60 guides the guided portion 91 of the lid 80, thereby enabling the lid 80 to be assembled to the base material 60. The guided portion 91 of the lid 80 is set to come into contact with the base material 20 when attempting to assemble the lid 80 to the base material 20, so that the lid 80 is not mistakenly assembled to the base material 20.

[0076] In addition to preventing incorrect assembly of the lid 40 and the base material 60, this also prevents incorrect assembly of the base material 20 and the lid 80.

[0077] Refer to Figures 4A and 4B. Thirdly, in the second vehicle misassembly prevention structure 10, the lid 40 can be assembled to the base material 20 by sliding it after it overlaps with the base material 20, and the lid 80 can be assembled to the base material 60 by sliding it after it overlaps with the base material 60.

[0078] The present invention employs an assembly prevention structure according to the present invention for products that are assembled by sliding. Furthermore, the present invention is applicable to all types of assembled products, including, for example, products where components are overlapped and simultaneously fitted together.

[0079] Refer to Figures 6, 7B, and 7C. Fourth, in the third vehicle misassembly prevention structure 10, the guided portion 51 of the lid 40 contacts the base material 60 when attempting to overlap the lid 40 onto the base material 60, and the guided portion 91 of the lid 80 contacts the base material 20 when attempting to overlap the lid 80 onto the base material 20.

[0080] The guided portions 51 and 91 may be set so that when the lids 40 and 80 overlap the base materials 20 and 60 and slide, they come into contact with any part of the base materials 20 and 60. However, in this embodiment, the lids 40 and 80 make contact with the base materials 20 and 60 before sliding, so incorrect assembly can be prevented early on.

[0081] Refer to Figure 6. Fifth, in the fourth vehicle misassembly prevention structure 10, the fitting portions 44, 49, 54, 55 of the lid 40 fit onto the fitting portions 23, 29, 32, 34 of the base material 20, thereby maintaining the assembly between the base material 20 and the lid 40, and the guided portion 91 of the lid 40 is connected to the first fitting portion 44 of the lid 40 (one of the fitting portions 44, 49, 54, 55), and the fitting portions 84, 89, 94, 95 of the lid 80 fit onto the fitting portions 63, 69, 72, 74 of the base material 60, thereby maintaining the assembly between the base material 60 and the lid 80, and the guided portion 91 of the lid 80 is connected to the first fitting portion 84 of the lid 80 (one of the fitting portions 84, 89, 94, 95).

[0082] The guided portion 51 of the lid 40 is connected to the first fitted portion 44 of the lid 40, thus increasing the rigidity of both. Similarly, the guided portion 91 of the lid 80 is connected to the first fitted portion 84 of the lid 80, thus increasing the rigidity of both. Note that the base materials 20 and 60 only need to have at least one fitted portion, and the lids 40 and 80 that correspond to the fitted portions only need to have at least one fitted portion.

[0083] Refer to Figure 1. Sixth, in any one of the second to fifth vehicle misassembly prevention structures 10, the base material 20 and the lid 40 are assembled together to form a first opening / closing body 15 (first assembly), the base material 60 and the lid 80 are assembled together to form a second opening / closing body 16 (second assembly), and the first opening / closing body 15 and the second opening / closing body 16 are provided on a vehicle exterior member 11, which is a common component.

[0084] The base material 20, lid 40, base material 60, and lid 80 are provided on the vehicle exterior member 11, which is a common component, and are often manufactured at the same time, increasing the likelihood of incorrect assembly. Therefore, the prevention structure of the present invention is particularly suitable. The first opening / closing body 15 and the second opening / closing body 16 may be provided on separate and different components, and may even be provided on different vehicles.

[0085] (Other structures to prevent incorrect assembly) Refer to Figure 8. The first opening / closing body 15 is attached to the vehicle exterior member 11 via the first mounting adapter 17. That is, the first opening / closing body 15 is supported so as to be swingable relative to the first mounting adapter 17, and the first mounting adapter 17 is attached to the vehicle exterior member 11. Both ends of the first mounting adapter 17 (relative to the length direction L, left and right direction in Figure 8) are screwed together with first tapping screws 17a.

[0086] The second opening / closing body 16 is attached to the vehicle exterior member 11 via a second mounting adapter 18. That is, the second opening / closing body 16 is supported so as to be swingable relative to the second mounting adapter 18, and the second mounting adapter 18 is attached to the vehicle exterior member 11. Both ends of the second mounting adapter 18 (relative to the length L) are screwed together with second tapping screws 18a.

[0087] With respect to the length L, the spacing S1 between the first tapping screws 17a, 17a is smaller than the spacing S2 between the second tapping screws 18a, 18a (S1 < S2). Therefore, incorrect assembly of the first mounting adapter 17 and the second mounting adapter 18 to the vehicle exterior member 11 can be prevented.

[0088] Refer to Figure 4C. The base material 20 of the first opening / closing body 15 has an arm portion 26 that extends from the central part 20a, which is the swing center of the base material 20, in the direction that the back surface 41 of the lid 40 faces (downward in Figure 4C).

[0089] Refer to Figure 7B. The base material 60 of the second opening / closing body 16 has an arm portion 66 that extends radially outward from the central part 60a which is the swing center. In detail, the arm portion 66 extends radially outward so as it moves away from the direction in which the back surface 81 of the lid 80 (see Figure 5B) is facing (downward in Figure 7B) (diagonally downward to the left in Figure 7B).

[0090] Refer to Figure 9. If the second opening / closing body 16 is incorrectly assembled to the first mounting adapter 17, the tip 66a of the arm portion 66 will come into contact with the wall surface of the storage space 17b of the first mounting adapter 17, and the first opening / closing body 15 will protrude from the storage space 17b of the second mounting adapter 18. This prevents incorrect assembly of the second opening / closing body 16 and the first mounting adapter 17.

[0091] Refer to Figure 10. If the first opening / closing body 15 is mistakenly assembled to the second mounting adapter 18, and the second mounting adapter 18 is then assembled to the vehicle exterior member 11, the edge 40a closest to the center 20a, which is the swing center of the first opening / closing body 15, will come into contact with the opening in a pushing motion, while the edge 40b further from the center 20a will form a gap G between itself and the opening. This prevents incorrect assembly of the first opening / closing body 15 and the second mounting adapter 18.

[0092] Refer to Figures 3A to 4E and Figures 7A to 7C. Seventh, in the first vehicle misassembly prevention structure 10, the lid 40 (second member) can be assembled to the base material 20 (first member) by sliding after overlapping it with the base material 20, and the guided portion 51 of the lid 40 comes into contact with the base material 60 (third member) when attempting to overlap the lid 40 with the base material 60.

[0093] Since the lid 40 makes contact with the base material 60 before sliding, incorrect assembly can be prevented early on.

[0094] Eighth, in the vehicle misassembly prevention structure described in the first, the lid 40 can be assembled to the base material 20 by sliding after overlapping with the base material 20, and the guided portion 51 of the lid 40 comes into contact with the base material 60 when the lid 40 slides relative to the base material 60.

[0095] Refer to Figure 6. Ninth, in the vehicle misassembly prevention structure 10 described in the first, the fitting portions 44, 49, 54, and 55 of the lid 40 fit onto the fitting portions 23, 29, 32, and 34 of the base material 20, thereby maintaining the assembly between the base material 20 and the lid 40, and the guide portion 91 of the lid 40 is connected to the first fitting portion 44 of the lid 40 (one of the fitting portions 44, 49, 54, and 55).

[0096] Since the guided portion 51 of the lid 40 is connected to the first fitted portion 44 of the lid 40, the rigidity of both is increased. Note that the base material 20 only needs to have at least one fitted portion, and the fitted portion of the lid 40 corresponding to the fitted portion also only needs to have at least one.

[0097] Tenth, in the vehicle misassembly prevention structure 10 described in the first, the guide portion 71 of the base material 60 guides the guided portion 91 of the lid 80, thereby enabling the lid 80 to be assembled to the base material 60, and the guided portion 91 of the lid 80 is set to come into contact with the base material 20 when attempting to assemble the lid 80 to the base material 20, so as to prevent the lid 80 from being mistakenly assembled to the base material 20.

[0098] Eleventh, in the vehicle misassembly prevention structure 10 described in the tenth, the lid 80 can be assembled to the base material 60 by sliding it after it overlaps with the base material 60, and the guided portion 91 of the lid 80 comes into contact with the base material 20 when attempting to overlap the lid 80 with the base material 20.

[0099] Since the lid 80 makes contact with the base material 20 before sliding, incorrect assembly can be prevented early on.

[0100] Twelfth, in the vehicle misassembly prevention structure 10 described in the tenth, the lid 80 can be assembled to the base material 60 by sliding after overlapping with the base material 60, and the guided portion 91 of the lid 80 contacts the base material 20 when the lid 80 slides relative to the base material 20.

[0101] Thirteenth, in the vehicle misassembly prevention structure 10 described in paragraph 10, the fitting portions 84, 89, 94, and 95 of the lid 80 fit onto the fitting portions 63, 69, 72, and 74 of the base material 60, thereby maintaining the assembly between the base material 60 and the lid 80, and the guide portion 91 of the lid 80 is connected to the first fitting portion 84 of the lid 80 (one of the fitting portions 84, 89, 94, and 95).

[0102] Since the guided portion 91 of the lid 80 is connected to the first fitted portion 84 of the lid 80, the rigidity of both is increased. Note that the base material 60 only needs to have at least one fitted portion, and the fitted portion of the lid 80 corresponding to the fitted portion also only needs to have at least one.

[0103] Refer to Figure 1. Fourteenth, in any one of the vehicle misassembly prevention structures 10 of the 10th to 13th, the base material 20 and the lid 40 are assembled together to form a first opening / closing body 15 (first assembly), the base material 60 and the lid 80 are assembled together to form a second opening / closing body 16 (second assembly), and the first opening / closing body 15 and the second opening / closing body 16 are provided on a vehicle exterior member 11 (common member).

[0104] The base material 20, lid 40, base material 60, and lid 80 are provided on the vehicle exterior member 11, which is a common component, and are often manufactured at the same time, increasing the likelihood of incorrect assembly. Therefore, the prevention structure of the present invention is particularly suitable. The first opening / closing body 15 and the second opening / closing body 16 may be provided on separate and different components, and may even be provided on different vehicles.
