[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-248900 Summary of the Invention [Problem to be solved by the invention]

[0008] In the vehicle front structure including the mounting structure described in Patent Document 1, a main hook provided on the radiator support engages with a main fastening portion provided on the headlamp unit. This results in an assembly error of the headlamp unit to the radiator support member. Furthermore, because the structure involves assembling an exterior member to the radiator support, factors such as dimensional errors in the exterior member may result in a large assembly error between the headlamp and the exterior member. This can cause problems, such as impairing the symmetry of the vehicle in the vehicle width direction, i.e., the vehicle's appearance. [Means for solving the problem]

[0009] Various aspects of a vehicle front structure and a method for assembling the vehicle front structure to solve the above problems will be described. [Aspect 1] A front structure of a vehicle comprising: a pair of headlamps spaced apart in a vehicle width direction; an exterior member provided between the pair of headlamps; and a support member located rearward of the exterior member and to which the headlamps and the exterior member are attached, wherein the exterior member has a first inclined surface that abuts against the headlamp in the vehicle width direction, the headlamp has a second inclined surface that is inclined along the first inclined surface, and the first inclined surface is inclined so as to be positioned higher or lower as it approaches an outer portion in the vehicle width direction, and the support member has a main body to which the exterior member is attached and a support member that fixes the main body to a vehicle body. a main body fixing portion that fastens the mounting portions to the main body portion at a position where the first inclined surface and the second inclined surface are in contact with each other; a pair of mounting portions that are connected to both ends of the main body portion in the vehicle width direction and to which the pair of headlamps are respectively attached; and a fastening portion that fastens the mounting portions to the main body portion at a position where the first inclined surface and the second inclined surface are in contact with each other, wherein the support member comprises a support mechanism that supports the mounting portions to the main body portion by allowing the mounting portions to be changed in position relative to the main body portion in the vehicle width direction when the main body portion and the mounting portions are not fastened to each other by the fastening portions, while restricting the mounting portions from being changed in position relative to the main body portion in a direction different from the vehicle width direction.

[0010] According to the above configuration, when the main body portion and the mounting portions are not fastened by the fastening portions, the exterior member is attached to the main body portion, and a pair of headlamps are respectively attached to the pair of mounting portions. Furthermore, the support mechanism allows the position of the mounting portions to be changed relative to the main body portion in the vehicle width direction, while restricting the position of the mounting portions to be changed relative to the main body portion in the front-to-rear direction of the vehicle, allowing the headlamp to be moved toward the exterior member from the outside in the vehicle width direction. This allows the second inclined surface of the headlamp to contact the first inclined surface of the exterior member from the outside in the vehicle width direction. Furthermore, the main body portion and the mounting portions are fastened by the fastening portions at a position where the first inclined surface and the second inclined surface contact each other. In this way, the support member, with the main body portion and the mounting portions fastened by the fastening portions, is fixed to the vehicle body by the main body fixing portions. This improves the assembly accuracy of the exterior member and the headlamp.

[0011] [Aspect 2] The support mechanism includes a long hole provided in one of the main body portion and the mounting portion and extending in the vehicle width direction, a hole provided in the other of the main body portion and the mounting portion, a bolt inserted into the long hole and the hole, and a nut that clamps the main body portion and the mounting portion together in cooperation with the bolt, in the front structure of a vehicle described in [Aspect 1].

[0012] According to the above configuration, the support mechanism is configured by the elongated hole provided in one of the main body and the mounting part, the hole provided in the other of the main body and the mounting part, the bolt, and the nut, so that the support mechanism can be realized with a simple configuration.

[0013] [Aspect 3] The mounting portion has a mounting portion main body and a connecting portion that protrudes from the mounting portion main body toward the main body in the vehicle width direction, the main body has a guide groove portion that opens on a side of the main body and extends in the vehicle width direction, and into which the connecting portion is inserted, the guide groove portion is configured to abut against the connecting portion to guide movement of the connecting portion in the vehicle width direction when the main body and the mounting portion are not fastened by the fastening portion, and the long hole is provided in the guide groove portion.

[0014] According to the above configuration, when the main body and the mounting portion are not fastened by the fastening portion, the guide groove guides movement of the connecting portion in the vehicle width direction. This makes it easier to abut the second inclined surface of the headlamp against the first inclined surface of the exterior member from the vehicle width direction. This improves the assembly accuracy of the exterior member and the headlamp.

[0015] [Aspect 4] The vehicle front structure according to [Aspect 3], wherein the connecting portion and the guide groove portion are provided in plural and spaced apart from each other in the vertical direction of the vehicle.

[0016] According to the above configuration, by providing a plurality of connecting portions and guide groove portions, it is possible to stabilize the change in position of the attachment portion relative to the main body portion in the vehicle width direction. [Aspect 5] A method for assembling a front structure of a vehicle according to any one of [Aspect 1] to [Aspect 4], comprising the steps of: fixing the main body portion to the vehicle body via the main body fixing portion; supporting the mounting portion relative to the main body portion by the support mechanism; attaching the exterior member to the main body portion; attaching the headlamp to the mounting portion; changing the position of the mounting portion relative to the main body portion in the vehicle width direction to bring the first inclined surface and the second inclined surface into contact; and fastening the mounting portion to the main body portion by the fastening portion.

[0017] According to the above method, the same effects as those of the above [Aspect 1] can be achieved. [Effects of the Invention]

[0018] According to the vehicle front structure and the method for assembling the same according to the present invention, the precision of assembling the exterior member and the headlamp is improved. [Brief explanation of the drawings]

In this way, the upper support mechanism 80 and the lower support mechanism 90 support the mounting portion 50 relative to the main body portion 31.

[0075] Note that, when the main body portion 31 and the mounting portion 50 are not fastened by the bolts 69, the upper support mechanism 80 and the lower support mechanism 90 support the mounting portion 50 relative to the main body portion 31 while allowing the position of the mounting portion 50 to be changed relative to the main body portion 31 in the vehicle width direction W. On the other hand, the upper support mechanism 80 and the lower support mechanism 90 support the mounting portion 50 relative to the main body portion 31 by restricting the position of the mounting portion 50 from being changed relative to the main body portion 31 in directions different from the vehicle width direction W, i.e., in the front-rear direction L and the up-down direction Z. Note that the elongated hole 81 allows the position of the bolt 84 to be changed in the vehicle width direction W, while restricting the positional displacement of the bolt 84 in the front-rear direction L. Furthermore, the elongated hole 91 allows the position of the bolt 94 to be changed in the vehicle width direction W, while restricting the positional displacement of the bolt 94 in the front-rear direction L. Furthermore, the bolt 84 and nut 82, and the bolt 94 and nut 92 restrict the position of the mounting portion 50 from being changed relative to the main body portion 31 in the up-down direction Z.

[0076] The upper guide groove portion 37 is configured to abut against the upper connecting portion 60 to guide movement of the upper connecting portion 60 in the vehicle width direction W when the main body portion 31 and the mounting portion 50 are not fastened together by the bolt 69. The lower guide groove portion 38 is configured to abut against the lower connecting portion 70 to guide movement of the lower connecting portion 70 in the vehicle width direction W when the main body portion 31 and the mounting portion 50 are not fastened together by the bolt 69.

[0077] <Exterior component installation process> As shown by the two-dot chain line in FIG. 7, in the exterior member attaching step, the exterior member 20 is disposed in front of the main body portion 31 and attached to the main body portion 31.

[0078] <Headlamp installation process> As shown in FIG. 7, in the headlamp mounting step, the headlamp 10 is placed in front of the mounting portion 50 and mounted to the mounting portion 50.

[0079] At this time, the mounting portion 50 is moved outward to a position where the outward movement of the bolt 94 is restricted by the outer end of the elongated hole 91 in the vehicle width direction W. As a result, a gap is generated between the first inclined surface 23 and the second inclined surface 13 in the vehicle width direction W.

[0080] <Position change process> 8, in the position changing step, the position of the mounting portion 50 relative to the main body portion 31 in the vehicle width direction W is changed to bring the first inclined surface 23 and the second inclined surface 13 into contact with each other. That is, by moving the headlamp 10 inward in the vehicle width direction W, i.e., toward the exterior member 20, the first inclined surface 23 and the second inclined surface 13 come into contact with each other.

[0081] <Fascinating process> As shown in FIG. 8, in the fastening step, the attachment portion 50 is fastened to the main body portion 31 with a bolt 69.

[0082] In the fastening step, first, the front end 41 of the main body fixing part 40 is placed on the upper upper wall 33a of the main body part 31 so that the elongated hole 42, elongated hole 81, and nut 65 overlap with the elongated hole 43 and nut 48, respectively.

[0083] Next, the mounting portion 50 is fastened to the main body portion 31 with the bolt 69 at a position where the first inclined surface 23 and the second inclined surface 13 contact each other. At this time, the bolt 69 further fastens the main body fixing portion 40 to the main body portion 31.

[0084] <Body part fixing process> As shown in Figure 8, in the main body fixing process, the rear end of the extension portion 45 of the main body fixing portion 40 is fastened to the vehicle body (both not shown) with a bolt, thereby fixing the main body portion 31 to the vehicle body via the main body fixing portion 40.

[0085] <Operation of this embodiment> As shown in FIG. 7 , in a state in which the main body portion 31 and the mounting portion 50 are not fastened together by the bolts 69, the exterior member 20 is attached to the main body portion 31, and the headlamp 10 is attached to the mounting portion 50. Furthermore, each of the support mechanisms 80 and 90 allows the position of the mounting portion 50 to be changed relative to the main body portion 31 in the vehicle width direction W, while restricting the position of the mounting portion 50 from being changed relative to the main body portion 31 in directions other than the vehicle width direction W. This allows the headlamp 10 to be moved toward the exterior member 20 from the outside in the vehicle width direction W. This allows the second inclined surface 13 of the headlamp 10 to come into contact with the first inclined surface 23 of the exterior member 20 from the outside in the vehicle width direction W. Furthermore, the main body portion 31 and the mounting portion 50 are fastened together by the bolts 69 at a position where the first inclined surface 23 and the second inclined surface 13 come into contact with each other. In this way, the support member 30, in a state in which the main body portion 31 and the mounting portion 50 are fastened together by the bolts 69, is fixed to a vehicle body (not shown) by the main body fixing portion 40.

[0086] <Effects of this embodiment> (1) Each of the support mechanisms 80, 90 allows the position of the mounting portion 50 relative to the main body portion 31 to be changed in the vehicle width direction W when the main body portion 31 and the mounting portion 50 are not fastened together by the bolts 69. On the other hand, each of the support mechanisms 80, 90 supports the mounting portion 50 relative to the main body portion 31 by restricting the position of the mounting portion 50 relative to the main body portion 31 from being changed in directions other than the vehicle width direction W.

[0087] According to this configuration, the above-mentioned effects are achieved, and therefore the precision of assembling the exterior member 20 and the headlamp 10 is improved. (2) The upper support mechanism 80 has an elongated hole 81 provided in the main body 31, a hole 83 provided in the mounting portion 50, a bolt 84 inserted through the elongated hole 81 and the hole 83, and a nut 82. The lower support mechanism 90 has an elongated hole 91 provided in the main body 31, a hole 93 provided in the mounting portion 50, a bolt 94 inserted through the elongated hole 81 and the hole 83, and a nut 92.

[0088] According to this configuration, the support mechanisms 80, 90 are respectively constituted by the elongated holes 81, 91 provided in the main body 31, the holes 83, 93 provided in the mounting portion 50, the bolts 84, 94, and the nuts 82, 92. Therefore, the support mechanisms 80, 90 can be realized with a simple configuration.

[0089] (3) When the main body 31 and the mounting portion 50 are not fastened together by the bolts 69, the upper guide groove 37 is configured to abut against the upper connecting portion 60 to guide the movement of the upper connecting portion 60 in the vehicle width direction W. The same is true for the lower guide groove 38 and the lower connecting portion 70.

[0090] According to this configuration, when the main body 31 and the mounting portion 50 are not fastened together by the bolts 69, the upper guide groove 37 guides the movement of the upper connecting portion 60 in the vehicle width direction W. This makes it easier to bring the second inclined surface 13 of the headlamp 10 into contact with the first inclined surface 23 of the exterior member 20 from the vehicle width direction W. This improves the accuracy of assembling the exterior member 20 and the headlamp 10 together.

[0091] (4) The upper connecting portion 60, the lower connecting portion 70, the upper guide groove portion 37, and the lower guide groove portion 38 are provided at intervals in the vertical direction Z. According to this configuration, by providing a plurality of connecting portions and guide groove portions, it is possible to stabilize the change in position of the attachment portion 50 relative to the main body portion 31 in the vehicle width direction W.

[0092] (5) The method for assembling the front structure of a vehicle includes a mounting portion supporting step, an exterior member mounting step, a headlamp mounting step, a position changing step, a fastening step, and a main body fixing step. According to this method, it is possible to achieve the same effect as effect (1) above.
