[0010] An attachment structure and a vehicle according to one embodiment will be described below with reference to Figures 1 to 6. Figure 1 is a perspective view showing the configuration of a portion of a vehicle according to one embodiment. Figures 2 and 3 are views of the bracket as seen from the front and rear, respectively. Figures 4 to 6 are a front view, a perspective view, and a cross-sectional view of the attachment portion, respectively.

[0011] In the drawings, X, Y, and Z indicate three mutually orthogonal directions. In this example, the width direction of the vehicle 1 is designated as X, the front-rear direction as Y, and the height direction (up-down direction) as Z. Note that in each drawing, the configuration is enlarged, reduced, or omitted as appropriate for ease of explanation.

[0012] The vehicle 1 is, for example, a truck, and includes a body frame, a plurality of body panel members that form the outer shell of the body of the vehicle, and various on-board devices such as an engine mounted on the body frame.

[0013] 1, the vehicle 1 has a front portion 10. For example, the front portion 10 of the vehicle 1 includes a front panel 11 as a first member constituting the front portion of the vehicle 1, body side panels 12 as second members constituting the side portions of the vehicle 1, and headlamps 13 arranged at both ends in the vehicle width direction. For example, the front panel 11 is a plate-shaped panel member disposed intersecting the longitudinal direction of the vehicle and extending along the vehicle width direction and the vertical direction, and is an example of a body panel member. For example, the front panel 11 includes a plate-shaped bracket base 112 having a base hole 112a formed therein. The movable mounting portion 20 includes a first bracket 21, a second bracket 22, a first shaft member 23, and a second shaft member 24, and the headlamp 13 is mounted to the bracket base 112 of the front panel 11 by the movable mounting portion 20. The bracket base 112 constitutes a part of the front panel 11, and in this embodiment, the first bracket 21 of the movable mounting portion 20 is fastened to the bracket base 112 of the front panel 11. The base hole 112a is a through-hole that penetrates the bracket base 112 in the thickness direction.

[0014] The body side panel 12 is an example of a body panel member, and is provided at both ends of the vehicle 1 on the outer side in the vehicle width direction. A plurality of fastening holes 12a are formed in predetermined locations on the front part of the body side panel 12, to which mounting pieces 135, 136 of the headlamp 13 are fastened.

[0015] The headlamp 13 includes a light-emitting unit 131 having a light-emitting element such as an LED, and a lens cover member 132 having a lens portion 132a that transmits light from the light-emitting unit 131 and is arranged on the front side of the light-emitting unit 131. The lens cover member 132 has a plurality of attachment pieces 133-136 on its outer periphery. The plurality of attachment pieces 133-136 are configured, for example, in the shape of a rectangular flat plate. The plurality of attachment pieces 133-136 are configured in the shape of a flat plate extending in the vehicle width direction and the up-down direction in the front portion 10 of the vehicle 1, and each have attachment holes 133a, 134a, 135a, 136a that are through-holes that penetrate in the thickness direction. The plurality of attachment pieces 133-136 may be part of the lens cover member 132 having the lens portion 132a, or may be bracket members formed separately from the lens portion 132a.

[0016] For example, in the movable mounting part 20 and the fixed mounting part 30, the shaft parts 231, 241 of the first shaft member 23 and the second shaft member 24 face the same direction and are arranged, for example, along the longitudinal direction of the vehicle 1. Furthermore, the multiple plate-like parts that are fastened together by overlapping each other, i.e., the multiple mounting pieces 133-136, the plate-like parts around the holes 21a, 21b of the first bracket 21, or the plate-like part around the third hole 22a of the second bracket 22, are each arranged in an orientation such that their thickness direction is along the axial direction of the first shaft member 23 or the second shaft member 24. For example, the movable mounting part 20 and the fixed mounting part 30 are arranged in an orientation such that the axial direction of the shaft members 23, 24 and the fastening member B is along the longitudinal direction of the vehicle 1 (direction Y in the figure).

[0017] The headlamp 13 has two mounting pieces 133, 134 located on the center side in the vehicle width direction, which are connected to the front panel 11 via movable mounting parts 20, 20. In this embodiment, as an example, the two mounting pieces 133, 134 are fastened via the movable mounting parts 20 to a bracket base 112 which is fastened to the front panel 11.

[0018] On the other hand, in this embodiment, the two mounting pieces 135, 136 on the outer sides of the headlamp 13 in the vehicle width direction are fastened to the body side panel 12 by fixed mounting parts 30 that do not have a position adjustment mechanism. In other words, one side and the other side of the headlamp 13 are fastened to different members, and at least one mounting part is fastened by a movable mounting part 20 that has a position adjustment mechanism.

[0019] 2 to 6, the movable mounting portion 20 (mounting structure) includes a first bracket 21, a second bracket 22, a first shaft member 23, and a second shaft member 24. In this embodiment, the two movable mounting portions 20 share the first bracket 21. Therefore, two each of the second brackets 22, first shaft members 23, and second shaft members 24 are arranged on one first bracket 21, thereby constituting two movable mounting portions 20.

[0020] The first bracket 21 is in the shape of a plate made of, for example, a metal material. For example, the first bracket 21 includes a flat mounting plate portion 211 extending in the width direction and up and down directions of the vehicle 1, and a return piece 212 bent from the lower end of the mounting plate portion 211 toward the rear side. At least a portion of the first bracket 21 is disposed opposite a bracket base 112 provided on the front panel 11.

[0021] The first bracket 21 has a first hole 21a to be fastened to the second bracket 22, a second hole 21b to be fastened to mounting pieces 133, 134 of the headlamp 13 to be attached, for example, and a fastening hole 21c to be fastened to the bracket base 112. In this embodiment, the second bracket 22 is fastened to two locations on the first bracket 21, and therefore the first hole 21a and the second hole 21b are formed in two locations each.

[0022] The first hole 21a is disposed at a position overlapping with the third hole 22a of the second bracket 22. That is, the first holes 21a are formed in two locations on the mounting plate portion 211. The first holes 21a are through-holes that penetrate the first bracket 21 in the thickness direction, and are formed, for example, in a circular shape that corresponds to the outer shape of the first shaft member 23 described below. The first bracket 21 is fastened to the second bracket 22 by the first shaft member 23, which has a shaft portion 231 that is inserted into the first hole 21a and the third hole 22a.

[0023] Furthermore, a plurality of restricting protrusions 213 are provided on the first bracket 21 at predetermined locations corresponding to the edges of the second bracket 22. The restricting protrusions 213 protrude from the first bracket 21 toward the rear side on which the second bracket 22 is disposed, and are disposed, for example, at positions corresponding to the sides of the fastening plate portion 221 of the second bracket 22, thereby restricting the attachment position of the fastening plate portion 221. For example, the restricting protrusions 213 are formed by bosses attached to the first bracket 21, or fastening members fastened to the first bracket 21, etc.

[0024] The second holes 21b are through-holes that penetrate the first bracket 21 in the thickness direction. In this embodiment, the two second holes 21b formed in the first bracket 21 are disposed opposite, for example, mounting pieces 133, 134 of the headlamp 13 to which the bracket 21 is to be attached. The second holes 21b are formed in a circular shape that is larger than the outer shape of the second shaft member 24, which will be described later.

[0025] The fastening holes 21c are through-holes that penetrate the first bracket 21 in the thickness direction. For example, two are provided at the upper end. The fastening holes 21c are fastened to the front panel 11 side by fastening members B such as bolts. Specifically, the first bracket 21 is fastened at the fastening holes 21c to base holes 112a formed in a bracket base 112, which is a member on the front panel 11 side.

[0026] The second bracket 22 is a plate-like member made of, for example, a metal material. The second bracket 22 is disposed opposite the rear surface side of the mounting plate portion 211 of the first bracket 21 and is fastened to the first bracket 21.

[0027] The second bracket 22 is configured as a rectangular plate having a step 22b in the center. The second bracket 22 has a fastening plate portion 221 in which the third hole 22a is formed, a pressing plate portion 222 arranged opposite one side of the head portion 242 of the second shaft member 24 disposed in the second hole 21b, and a support plate 223 (support member).

[0028] The fastening plate portion 221 is configured in a rectangular flat plate shape. The fastening plate portion 221 has a third hole 22a, which is a through hole provided at a position overlapping with the first hole 21a of the first bracket 21. The first shaft member 23 is fastened to the third hole 22a and the first hole 21a.

[0029] On the other hand, the pressing plate portion 222 is configured in a rectangular flat plate shape and is a pressing member that is disposed opposite the head portion 242 of the second shaft member 24 to restrict axial movement of the second shaft member 24. The pressing plate portion 222 is connected to the fastening plate portion 221 via a step 22b that is approximately the same dimension as the thickness of the head portion 242 of the second shaft member 24, and the step 22b forms a predetermined gap G3 between the pressing plate portion 222 and the back surface of the first bracket 21.

[0030] The support plates 223 are plate-like members respectively erected on both sides of the pressing plate portion 222, and are, for example, welded to the side surfaces of the pressing plate portion 222. The pair of support plates 223 are fixed to the back surface of the first bracket 21, and are support members that support the pressing plate portion 222 on the back surface side of the first bracket 21.

[0031] The first shaft member 23 is, for example, a bolt, and includes a shaft portion 231 having an external thread portion and being inserted into the first hole 21 a and the third hole 22 a, and a head portion 232 that is larger than the first hole 21 a and the third hole 22 a. The first shaft member 23 fastens the first bracket 21 and the second bracket 22. A nut 25 having an internal thread portion is attached to the tip end of the shaft portion 231 of the first shaft member 23. A washer or other metal fitting may be interposed between the head portion 232 of the second shaft member 24 and the second bracket 22.

[0032] The second shaft member 24 is, for example, a bolt, and includes a shaft portion 241 having a male thread portion, and a head portion 242. The shaft portion 241 is inserted into the second hole 21b and the mounting hole 133a of the mounting piece 133 or the mounting hole 134a of the mounting piece 134, and the second shaft member 24 connects the first bracket 21 and the mounting piece 133 or the mounting piece 134, which are arranged on top of each other.

[0033] The outer diameter of the shaft portion 241 of the second shaft member 24 is smaller than the inner diameter of the second hole 21b, and a gap G1 is formed between the inner surface of the second hole 21b and the outer surface of the shaft portion 241 of the second shaft member 24. The outer diameter of the shaft portion 241 is also smaller than the inner diameter of the mounting holes 133a, 134a, and a gap G2 is formed between the inner surfaces of the mounting holes 133a, 134a and the outer surface of the shaft portion 241 of the second shaft member 24. In this embodiment, G1 is configured to be larger than G2. Therefore, the second shaft member 24 is fastened to the first bracket 21 and the mounting pieces 133, 134 so as to be movable by the gaps G1 and G2. A nut 26 having an internal thread is threadedly attached to the tip of the shaft portion 241.

[0034] For example, the head 242 is configured in the shape of a rectangular plate that is larger than the second hole 21b and the mounting holes 133a, 134a. A washer or other metal fitting may be interposed between the head 242 of the second shaft member 24 and the first bracket 21. The head 242 is disposed in the gap G3 between the back surface of the first bracket 21 and the pressing plate portion 222. The pressing plate portion 222 restricts the movement of the head 242 in the axial direction, and the head 242 is engaged around the second hole 21b of the first bracket 21.

[0035] The assembly process of the movable mounting portion 20 configured as described above will be described. First, as a pre-processing step, the bracket base 112 is fastened to the front panel 11. Meanwhile, as a pre-processing step, the support plate 223 is welded to the side of the pressing plate portion 222 of the second bracket 22 as shown in FIG. 3. Then, with the shaft portion 241 of the second shaft member 24 inserted into the second hole 21b, the second bracket 22 is placed on the first bracket 21 and fastened together by the first shaft member 23. As a result, as shown in FIG. 3, the second shaft member 24 is movably held by the second bracket 22. At this time, the shaft portion 241 of the second shaft member 24 is held in a protruding state from the second hole 21b of the first bracket 21, and the second shaft member 24 is movable relative to the first bracket 21 within a plane intersecting the axial direction.

[0036] Then, the fastening hole 21c of the first bracket 21 is aligned with the base hole 112a formed in the bracket base 112 on the front panel 11 side, and the first bracket 21 is fastened to the bracket base 112 with a fastening member B such as a bolt.

[0037] As a result of the above, the first bracket 21 is fastened to the bracket base 112 on the front panel 11 side, and the shaft portion 241 of the second shaft member 24 protrudes from the second hole 21b of the first bracket 21 toward the front of the vehicle, resulting in a temporary holding state.

[0038] Then, in the assembly process of the vehicle 1, the lens cover member 132 of the headlamp 13 is attached by covering the front panel 11 and the body side panel 12 from the front side of the front of the vehicle 1. At this time, first, of the four mounting pieces 133 to 136, two mounting pieces 135, 136 are positioned to face the fastening hole 12a formed in the body side panel 12, and the other two mounting pieces 133, 134 are positioned so that the second shaft member 24 protruding from the temporarily held first bracket 21 is inserted into the mounting holes 133a, 134a.

[0039] First, the mounting holes 135a, 136a are aligned with the fastening holes 12a formed on the body side panel 12, and the mounting pieces 135, 136 are fastened to the body side panel 12 with fastening members B. Thereafter, nuts 26 are tightened from the front sides of the mounting pieces 133, 134 that are aligned with the first bracket 21.

[0040] As a result of the above, the mounting pieces 135, 136 on the outer side of the lens cover member 132 of the headlamp 13 in the vehicle width direction are held to the body side panel 12 via the fixed mounting portion 30, and the mounting pieces 133, 134 are fastened to the front panel 11 via the movable mounting portion 20.

[0041] According to the vehicle 1 of this embodiment, the first bracket 21 and the second bracket 22 are fastened together to movably hold the second shaft member 24, which has a shaft portion 241 smaller than the second hole 21b of the first bracket 21. This allows dimensional variations during assembly to be absorbed, improving ease of assembly. That is, when one side is assembled to the front panel 11 and the other side is assembled to the body side panel 12, variations in the positions of the multiple fastening portions may occur. However, depending on design conditions, it may not be possible to adjust the positions of the fastening portions on the part to be attached. According to this embodiment, the first bracket 21 and the second bracket 22 are fastened together to movably hold the second shaft member 24, which has a shaft portion 241 smaller than the second hole 21b of the first bracket 21, relative to the first bracket 21, thereby absorbing dimensional variations. Furthermore, in this embodiment, the second bracket 22 can be used to temporarily hold the second shaft member 24 in a movable manner on the first bracket 21, so that the lens cover member 132 of the headlamp 13 can be placed on the front side of the front part of the vehicle 1 and the nut 26 can be attached, which improves workability.

[0042] The present invention is not limited to the above embodiment. For example, the arrangement and number of the multiple fastening portions and the specific shape of each member are not limited to those described above and can be modified as appropriate. Also, while the first member and the second member are the front panel 11 and the body side panel 12, respectively, the present invention is not limited to these and may be other members.

[0043] Although one embodiment of the present invention has been described above in detail, the present invention is not limited to the above embodiment and can be appropriately modified, improved, etc. The present invention is defined by the claims and includes all modifications within the meaning and scope of the claims.
