The present invention relates to a vehicle front structure in which a front exterior member such as a bumper is attached to a vehicle body together with a lamp body.

A lamp body such as a headlight is attached to the front part of the vehicle together with a front exterior member such as a bumper and a grill. The lamp body is attached to the vehicle body so that the design surface portion exposed to the outside of the vehicle is adjacent to the design surface portion of the front exterior member. Therefore, it is necessary to properly position the front exterior member and the lamp body when assembling to the vehicle body. As a countermeasure against this, a vehicle front structure has been devised in which the front exterior member and the lamp body can be appropriately positioned by adding a separate positioning member (see, for example, Patent Document 1).

In the vehicle front structure described in Patent Document 1, a positioning member is fastened and fixed to the lamp body mounting portion of the vehicle body frame together with the lamp body, and at this time, the contact claws extended to the positioning member regulate the position of the lamp body lens. It is designed to come into contact with the front of the piece. The bumper, which is the front exterior member, is locked and fixed to the positioning member whose position is regulated by the lamp lens in this way.

In the vehicle front structure described in Patent Document 1, since the bumper is attached to the positioning member whose position is regulated (positioned) on the lamp lens, the design surface portion of the bumper is accurately aligned with the design surface of the lamp lens. be able to.

Japanese Unexamined Patent Publication No. 2006-248483

However, in the case of the vehicle front structure described in Patent Document 1, although the bumper (front exterior member) can be positioned on the lamp lens via the positioning member, the positional relationship with the fixed portion on the vehicle body side is taken into consideration. Absent. Therefore, when the bumper is locked and fixed to the positioning member and then the end of the bumper is fastened and fixed to, for example, the fixed area on the outside in the vehicle width direction of the vehicle body, the end of the bumper and the outside in the vehicle width direction of the vehicle body Dimensional errors and the like of each member are accumulated and appear between the fixed area and the bumper, and the assembling property of the bumper to the vehicle body is lowered.

Therefore, the present invention is intended to provide a vehicle front structure capable of adjusting the relative positions of the front exterior member and the lamp body and improving the assembling property of the front exterior member with respect to the outer fixed region of the vehicle body. is there.

The vehicle front structure according to the present invention adopts the following configuration in order to solve the above problems.
That is, in the vehicle front structure according to the present invention, the outer region in the vehicle width direction is fastened and fixed to the outer fixed region on the outer side in the vehicle width direction of the vehicle body, and the inner region in the vehicle width direction is fixed in the vehicle width direction with respect to the outer fixed region. A lamp body to be fastened and fixed to the inner fixed region of the inner vehicle body (for example, the lamp body 9 of the embodiment) and a lamp body arranged at the front portion of the vehicle body and the outer end portion in the vehicle width direction are fastened to the outer fixed region of the vehicle body. The front exterior member to be fixed (for example, the front exterior member 10 of the embodiment) and the outer region in the vehicle width direction are fastened and fixed to the outer fixed region of the vehicle body, and the inner region in the vehicle width direction is the lamp body. The assembly auxiliary member (for example, the assembly auxiliary member 12 of the embodiment) that is locked to the vehicle width direction inner region of the front exterior member and the vehicle width direction inner region of the front exterior member is provided. Is a plate-shaped first claw portion (for example, the first claw portion 23 of the embodiment) extending from the inner region in the vehicle width direction to the rear of the vehicle and whose thickness direction substantially matches the vehicle width direction, and the inner region in the vehicle width direction. A plate-shaped second claw portion (for example, the second claw portion 27 of the embodiment) extending from the outer position in the vehicle width direction to the front of the vehicle and having a thickness direction substantially matching the vertical direction of the vehicle with respect to the first claw portion. The lamp body includes a claw locking portion (for example, the claw locking portion 25 of the embodiment) for locking the extension end side of the first claw portion of the assembly auxiliary member, and the assembly auxiliary member. In the assembled state, a locking hole is arranged at a position between the first claw portion and the second claw portion in the vehicle width direction and is accessible from the front of the vehicle (for example, the engagement of the embodiment). An exterior regulation piece (for example, the exterior regulation piece 9Ad of the embodiment) having a stop hole 33) is provided, and the front exterior member is the second claw portion of the assembly auxiliary member in the vehicle width direction inner region. An engaging hole (for example, the engaging hole 29 of the embodiment) formed at a corresponding position and into which the second claw portion is inserted from the rear of the vehicle, and the locking hole of the lamp body in the inner region in the vehicle width direction. It is provided with a regulation protrusion (for example, the regulation protrusion 40 of the embodiment) formed at a corresponding position and inserted into the locking hole from the front of the vehicle to regulate the relative displacement of the exterior regulation piece in the vehicle front-rear direction. It is characterized by that.

In this case, the lamp body and the front exterior member can be assembled to the vehicle body as follows, for example.
First, the assembly auxiliary member is temporarily assembled to the lamp body, and in that state, the lamp body is fastened and fixed to the outer fixing area and the inner fixing area of the vehicle body. When the assembly auxiliary member is temporarily assembled to the lamp body, the extension end side of the first claw portion of the assembly auxiliary member is locked by the claw locking portion of the lamp body. In this state, the position of the assembly auxiliary member can be adjusted in the vehicle width direction with respect to the lamp body by bending and deforming the first claw portion in the thickness direction.
Next, the temporarily assembled lamp body and the assembly auxiliary member are engaged with the inner region of the front exterior member in the vehicle width direction. At this time, the second claw portion of the assembly auxiliary member is inserted into the engaging hole of the front exterior member, and the regulating protrusion of the front exterior member is inserted into the locking hole of the exterior regulating piece of the lamp body. In the engaged state, the second claw portion can be easily bent and deformed in the vertical direction, so that the position of the front exterior member can be adjusted in the vertical direction with respect to the assembly auxiliary member. Further, the front exterior member is positioned in the vehicle front-rear direction with respect to the lamp body by inserting the regulation protrusion into the locking hole of the exterior regulation piece.
After that, the outer region in the vehicle width direction and the inner region in the vehicle width direction of the lamp body are fastened and fixed to the outer fixed region and the inner fixed region of the vehicle body, and the outer region in the vehicle width direction of the front exterior member is used as the outer fixed region of the vehicle body. Fix it. At this time, even if each component has a dimensional error or a tolerance, the front exterior member of the vehicle is provided by appropriately displacing the front exterior member in the vehicle width direction and the vertical direction with respect to the assembly auxiliary member and the lamp body. The outer region in the width direction can be easily fixed to the outer fixed region of the vehicle body.

The assembly auxiliary member has a plate shape whose thickness direction substantially coincides with the vehicle vertical direction with the base portion (for example, the base portion 19 of the embodiment) extending inward in the vehicle width direction from the fastening portion with the outer fixed region. The upper connecting piece (for example, the upper connecting piece 22u of the embodiment) extending outward in the vehicle width direction from the upper end position on the base side of the first claw portion and being connected to the base portion, and the thickness direction is the vehicle vertical direction. A lower connecting piece (for example, the lower connecting piece of the embodiment) which has a plate shape substantially matching the above and extends substantially horizontally from the lower end position on the base side of the first claw portion to the outside in the vehicle width direction and is connected to the base portion. A piece 22l) may be provided.

In this case, the upper connecting piece and the lower connecting piece that support the first claw portion have a plate shape whose thickness direction substantially matches the vertical direction of the vehicle, and both have a shape that extends similarly in the vehicle width direction. It bends in the vertical direction due to the input load in the direction. As a result, the assembly auxiliary member is easily bent and deformed in the vehicle width direction in the inner region in the vehicle width direction. Therefore, when adjusting the position of the assembly auxiliary member with respect to the lamp body in the vehicle width direction, the upper connecting piece and the lower connecting piece are deformed in the vehicle width direction together with the first claw portion to position the position in the vehicle width direction. The adjustment range can be widened, and the load acting on the first claw portion can be reduced.

The assembly auxiliary member is abbreviated as a base portion extending inward in the vehicle width direction from a fastening portion with the outer fixed region (for example, the base portion 19 of the embodiment) and a vehicle front-rear direction from the base end of the second claw portion. It may be configured to include a connecting wall (for example, the connecting wall 26 of the embodiment) extending in the orthogonal direction and connected to the base portion.

In this case, even if the second claw portion is arranged away from the base portion, the vertical displacement of the base end of the second claw portion can be regulated by the connecting wall extending in a direction substantially orthogonal to the vehicle front-rear direction. .. Therefore, when adjusting the position of the front exterior member in the vertical direction with respect to the assembly auxiliary member, the deformation of the base portion and the connecting wall is suppressed, and the front exterior member is deformed by the deflection deformation in the thickness direction of the second claw portion. It can be stably displaced in the vertical direction.

The lamp body has a plate shape whose thickness direction substantially matches the vehicle width direction with the lamp body case body (for example, the lamp body case body 9Aa of the embodiment) fixed to the vehicle body, and is formed from the lamp body case body. A support piece extending forward of the vehicle (for example, the support piece 9Ac of the embodiment) may be provided, and the exterior regulation piece may be connected to the support piece.

In this case, since the support piece is easily bent and deformed in the vehicle width direction, the position of the front exterior member can be easily adjusted in the vehicle width direction by the bending deformation of the support piece.

The design surface portion (for example, the design surface portion 9Bs of the embodiment) of the lamp body has a concave portion (for example, the concave portion 38 of the embodiment) that is recessed from the inner end portion in the vehicle width direction toward the outer side in the vehicle width direction. The design surface portion (for example, the design surface portion 10s of the embodiment) of the front exterior member has a convex shape portion (for example, the convex shape portion 39 of the embodiment) arranged in the concave shape portion. The second claw portion is arranged at a position inside the concave-shaped portion in a state where the assembly auxiliary member is assembled to the lamp body, and the engagement hole of the front exterior member is convex. It may be formed in the shape portion.

In this case, an engaging hole is formed in the convex portion of the design surface portion of the front exterior member, and the engaging hole is fitted with the second claw portion, so that the convex portion of the front exterior member becomes a lamp body. It is locked to the assembly auxiliary member in the concave portion of. Therefore, the design surface portion of the front exterior member protruding outward in the vehicle width direction can be stably engaged with the design surface portion of the lamp body, and the positioning accuracy is improved. As a result, the appearance design of the vehicle is enhanced.

In the vehicle front structure of the present invention, a displacement allowable portion (first claw portion engaged with the claw locking portion) in the vehicle width direction between the lamp body and the assembly auxiliary member, and the assembly auxiliary member and the front portion. The position of the front exterior member relative to the lamp body is adjusted by the vertical displacement allowance portion between the exterior members (the second claw portion on the assembly auxiliary member side fitted with the engagement hole of the front exterior member). can do. Therefore, the outer region of the front exterior member in the vehicle width direction can be easily assembled to the outer fixed region of the vehicle body while aligning the front exterior member and the lamp body. Therefore, when the vehicle front structure of the present invention is adopted, the relative positions of the front exterior member and the lamp body can be adjusted, and the assembling property of the front exterior member with respect to the outer fixed region of the vehicle body can be improved. ..
