Description

  The present invention relates to a taillight mounting structure.

Some vehicles such as automobiles have tail lights at the rear of the vehicle body. Since this taillight occupies a large weight in terms of appearance quality at the rear of the vehicle body, various shapes have been proposed in design.
For example, there is one in which a taillight is attached over a corner portion at the rear of the vehicle body (see Patent Document 1).

FIG. 6 is a rear perspective view of a vehicle for explaining a conventional taillight mounting structure.
As shown in FIG. 6, the tail light unit 100 has a housing that supports a bulb covered with a lens from the rear, a side wall portion 102 along the rear fender panel 101, and a tail gate (not shown). And a rear wall portion 104 extending along the line. The front edge of the side wall 102 is an inclined edge 102a that is inclined downward as it goes forward.
On the other hand, a side wall attaching part 105 to which the side wall part 102 of the tail light unit 100 is attached and a rear wall attaching part 106 to which the rear wall part 104 is attached are formed at the rear part of the vehicle body.

The tail light unit 100 thus formed is assembled so as to cover the corner portion from the rear to the front of the vehicle body. Specifically, the rear wall portion 104 is provided with a clip 107 protruding forward, and the rear wall portion 104 is engaged with the mounting hole 108 formed in the rear wall mounting portion 106. And the rear wall mounting portion 106 are fixed. On the other hand, the side wall portion 102 is formed with an engaging portion 109 that is opened toward the front, and the engaging portion 109 receives a boss portion 110 that protrudes sideways from the side wall mounting portion 105. The side wall portion 102 and the side wall mounting portion 105 are fixed.
Thus, the tail light unit 100 is attached to the vehicle body.

  By the way, in the state where the taillight unit 100 is assembled to the vehicle body, the outer surface of the taillight unit 100 and the exterior surface of the vehicle body (the rear fender panel 101 and the tailgate) are formed almost flush with each other. A gap (parting line) having a constant width is formed at the boundary portion.

However, since the tail light unit 100 described above is generally formed of a resin material, the tail light unit 100 is expanded and contracted by a temperature change.
Therefore, in the relatively large taillight unit 100, the clip 107 of the rear wall 104 can be moved in the vertical direction with respect to the taillight unit 100, and the thermal expansion or contraction of the taillight unit 100 due to expansion / contraction is achieved. There is known a configuration that absorbs water along the vertical direction.

  However, when the side wall 102 of the tail light unit 100 has the inclined edge 102a, when the tail light unit 100 expands / contracts, the parting line between the side wall 102 and the rear fender panel 101 is reduced / expanded. The width of the ring line is non-uniform along the extending direction. As a result, there is a problem that the appearance quality of the vehicle is impaired.

  Accordingly, an object of the present invention is to provide a taillight structure that can suppress the influence on the appearance quality due to the expansion and contraction of the taillight unit.

  In order to achieve the above object, the invention described in claim 1 is directed to a taillight mounting structure in which a taillight unit is mounted so as to cover a corner portion of a rear portion of a vehicle body from the rear side to the side.

It is formed in the long hole made into a direction, It is characterized by the above-mentioned.

  In the invention described in claim 2, the taillight unit is assembled from the rear to the front of the vehicle body, and the boss portion is attached to the front end portion of the holding portion in the assembly direction of the taillight unit. The receiving part is formed in the holding part.

  According to the first aspect of the present invention, when the tail light unit expands and contracts due to a temperature change, the rear wall portion is fixed to the rear wall mounting portion via the fixing point, and therefore the side wall portion is positively Displacement (thermal elongation or thermal contraction) will occur. At this time, since the holding portion is formed in a long hole shape along the extending direction of the inclined edge of the side wall portion, the holding portion moves relative to the boss portion in a state where the boss portion is accommodated and held. . That is, the side wall portion is displaced along the long axis direction of the holding portion (the extending direction of the inclined edge of the side wall portion). Therefore, the displacement of the side wall due to expansion / contraction can be absorbed along the extending direction of the inclined edge, so that the parting line between the inclined edge of the side wall and the peripheral member (for example, the rear fender panel) extends in the extending direction. A uniform width will be maintained along. Therefore, the influence on the appearance quality can be suppressed as much as possible.

  According to the second aspect of the present invention, by setting the receiving portion of the holding portion to the front end side (front end side of the assembly) of the holding portion, the tail light unit can be moved from the rear when the tail light unit is assembled. The boss portion is accommodated and held in the holding portion through the receiving portion simply by pushing. Thereby, the assembly | attachment property of a taillight unit can be maintained.

Thus, the inside of the holding portion 67 is relatively movable with the displacement of the side wall portion 51.

(Function)
Next, the operation will be described. In the following description, first, a method for assembling the tail light lower 8 will be described.
When the tail light lower 8 is assembled to the vehicle body 1, first, the clip 31 of the tail light lower 8 and the mounting hole 25 of the first mounting portion 11, and the mounting portion 61 of the tail light lower 8 and the boss clip 37 are aligned with each other. In this state, the tail light lower 8 is pushed in from the rear to the front (see arrow K in FIG. 3). Then, the clip 31 of the tail light lower 8 is inserted into the mounting hole 25 of the rear wall mounting portion 22, and the guide bar 38 of the boss clip 37 is inserted into the housing portion 62 of the mounting portion 61.

When the tail light lower 8 is further pushed in this state, the clip 31 is locked in the mounting hole 25 and the rear wall portion 52 is fixed to the rear wall mounting portion 22. That is, the rear wall portion 52 is fixed to the rear wall attachment portion 22 via the fixing points (clip 31 and attachment hole 25).
Further, the boss portion 39 of the boss clip 37 enters the holding portion 67 from the receiving portion 66 formed on the front end side in the assembling direction of the engaging portion 63, and the central portion in the long axis J direction in the holding portion 67. It will be housed and held.

  Thereafter, the screws 35 inserted into the upper and lower insertion holes 55 of the rear flange portion 54 of the tail light lower 8 are fastened and fixed to the fastening holes 28 of the rear wall attachment portion 22 of the first attachment portion 11. Thereby, the attachment of the tail light lower 8 is completed. Therefore, the tail light lower 8 is positioned in the longitudinal direction, the width direction, and the vertical direction of the vehicle body, and the tail light lower 8 is located between the tail light upper 7, the rear fender panel 4, and the tail gate 3, respectively. A parting line having a constant width (for example, parting line P1) is formed.

  By the way, when the tail light unit 6 expands and contracts due to a temperature change, the rear wall portion 52 is fixed to the rear wall mounting portion 22 via the fixing points (the clip 31 and the mounting hole 25). It will be positively displaced (thermal elongation and thermal contraction).

  Here, in the present embodiment, since the holding portion 67 of the mounting portion 61 is formed in a long hole shape along the inclined edge 56 of the side wall portion 51, the boss portion 39 is accommodated and held in the boss portion 39. It moves relative to it. That is, the side wall portion 51 is displaced along the major axis J direction of the holding portion 67 (the extending direction of the inclined edge 56 of the side wall portion 51). Therefore, since the displacement of the side wall 51 due to expansion / contraction can be absorbed along the extending direction of the inclined edge 56, the parting line P1 between the side wall 51 and the rear fender panel 4 is uniform along the extending direction. Will maintain the correct width. Below the tail light lower 8, the tail gate 3 and the rear fender panel 4 bulge outward from the outer surface of the tail light lower 8 (see FIG. 1), so the lower edge of the tail light lower 8 and the tail gate The parting line between 3 and the rear fender panel 4 is difficult to see. Therefore, even if the parting line between the lower edge of the tail light lower 8 and the tail gate 3 and the rear fender panel 4 slightly changes when the tail light lower 8 is displaced, there is no particular problem in appearance quality. .

Therefore, according to the present embodiment, the engaging portion 63 (holding portion 67) that is engaged with the boss portion 39 of the side wall attachment portion 23 is formed in a long hole shape along the inclined edge 56 of the side wall portion 51. The displacement of the side wall 51 due to expansion / contraction can be absorbed along the extending direction of the inclined edge 56. Therefore, the parting line can be maintained at a uniform width, and the influence on the appearance quality can be suppressed as much as possible.
Further, by setting the receiving portion 66 of the engaging portion 63 to the front end side (front end side of assembly) of the holding portion 67, the tail light lower 8 is directed from the rear to the front when the tail light lower 8 is assembled. The boss portion 39 is accommodated and held in the holding portion 67 through the receiving portion 66 simply by pushing in. Thereby, the assembly property of the tail light lower 8 can be maintained.

The technical scope of the present invention is not limited to the above-described embodiments, and includes those in which various modifications are made to the above-described embodiments without departing from the spirit of the present invention. In other words, the configuration described in the above-described embodiment is merely an example, and can be changed as appropriate.
For example, when the inclined edges 24 and 56 of the rear fender panel 4 and the tail light unit 6 are inclined downward as they go forward as in the above-described embodiment, the receiving portion 66 is provided on the lower end side of the holding portion 67. In contrast to this, in the case of inclining upward as it goes forward, it is preferable to form the receiving portion 66 at the upper end portion of the holding portion 67. In any case, it is preferable to form the receiving portion 66 on the front end side in the assembly direction of the tail light unit 6 in the holding portion 67.

In the above-described embodiment, the case where the taillight mounting structure of the present invention is employed in the taillight lower 8 has been described. However, the present invention is not limited to this and may be employed in the taillight upper 7.
Further, a plurality of mounting portions 61 may be provided on the side wall portion 51 as long as the rear wall portion 52 has at least one fixing point.
