  An example of a bumper mounting structure in a vehicle is shown in FIGS.

  17A is an exploded perspective view of the bumper portion of the vehicle showing the bumper mounting structure, FIG. 17B is a cross-sectional view taken along the line II of FIG. 17A, and 30 is a headlamp. , 31 is a bumper, 32 is an applicator, and 33 is a fender cover. A hook shape 34 for supporting the bumper 31 is formed integrally with the apparator 32, and a flange 31 a formed inside the bumper 31 is inserted into the hook shape 34 and locked.

  Another bumper mounting structure is shown in FIGS. 18 (a) and 18 (b).

  18A is an exploded perspective view of the bumper portion of the vehicle showing the bumper mounting structure, and FIG. 18B is a cross-sectional view taken along the line JJ of FIG. A hook shape 35 is integrally formed, and a flange 31 a formed on the inner side of the bumper 31 is inserted into the hook shape 35 and locked. In FIG. 18, the same elements as those shown in FIG.

  Thus, in the bumper mounting structure shown in FIG. 17, the applicator 32 is provided to keep the gap S (see FIG. 17B) between the bumper 31 and the lens of the headlamp 30 constant. The appartina 32 needs to be newly installed for each vehicle type.

  In the bumper mounting structure shown in FIG. 18, since the clip 35 is formed integrally with the housing of the headlamp 30, the hook shape 35 is deformed by an external force that acts on the headlamp 30 from the bumper 31 at the time of a light collision. There is a problem that the sealing effect of the sealing member 36 that seals the periphery of the lens of the headlamp 30 is impaired.

  Therefore, in Patent Document 1, a bumper mounting structure as shown in FIGS. 19 to 21 is proposed.

A locking portion for inserting and locking a flange formed on the upper edge of the bumper is formed at the lower portion, and the bent portion is disposed in front of the vehicle with respect to the fixing portion, and
When an external force is received from the bumper, the bumper holder moves in the vehicle front-rear direction and is fixed to the lamp at the lower portion.

According to a second aspect of the present invention, in the first aspect of the present invention, a clearance that allows movement of the flange of the bumper in the front-rear direction of the vehicle is formed in the engaging portion formed in the lower portion between the flange end portion. ,
The lamp mounting hole formed in the lower part is constituted by a long hole that is long in the longitudinal direction of the vehicle, and the width of the long hole on the vehicle front side or the rear side is set wider than the width on the other side. To do.

  The invention according to claim 3 is the invention according to claim 1 or 2, wherein the fixing portion formed at the upper end of the side portion is configured by a substantially horizontal plane and is formed at the end portion of the vertical wall portion. The fixing portion is fixed to the vehicle body in the vehicle width direction by a bolt.

  According to the first aspect of the present invention, the flange formed on the upper edge of the bumper is inserted into the locking portion formed at the lower portion of the bumper holder and locked, so that the lamp and the bumper fixed to the bumper holder are fixed. A high-accuracy positional relationship is ensured between them, and a gap (parting) between the two is kept constant and appearance is improved.

  Further, when the bumper moves in the vehicle front-rear direction at the time of a vehicle collision, the bumper holder is also moved by the bumper and the fixing to the lamp is released, so that the lamp is protected from the impact load and the damage is prevented. In this case, since the bent part of the bumper holder is arranged in front of the vehicle with respect to the fixed part and the side part of the bumper holder is arranged obliquely, when an external force is applied to the bumper at the time of the vehicle collision, the bumper holder is moved away from the ramp. It can be guided downward, avoiding bumper bumps against the lamp and preventing damage to the lamp.

  According to the invention described in claim 2, when the external force applied to the bumper is relatively small, the movement of the bumper is absorbed by the gap formed between the locking portion of the bumper holder locking portion and the flange of the bumper. Can do. When a larger external force is applied to the bumper, the flange of the bumper comes into contact with the locking portion of the bumper holder and moves the bumper holder in the vehicle front-rear direction. A long hole is formed in the lower part of the bumper holder in the vehicle front-rear direction. Therefore, slight movement of the bumper holder is allowed within the range of the length of the long hole, transmission of external force from the bumper holder to the lamp is interrupted, and damage to the bumper holder itself as well as the lamp can be prevented. Thus, the movement of the bumper holder in the vehicle front-rear direction can be allowed with a simple configuration, and the fixation between the bumper holder and the lamp can be released.

  In addition, when a large impact load is applied to the bumper, the bumper holder and the fixture for fixing the lamp, such as a clip, are damaged or detached, and the bumper holder and the lamp are completely separated from each other. The damage is prevented.

  According to the third aspect of the invention, the fixing portion formed at the upper end of the side portion of the bumper holder is constituted by a substantially horizontal plane, and the fixing portion formed at the end portion of the vertical wall portion of the bumper holder is mounted on the vehicle body by the bolt. As the bumper is moved in the vehicle width direction, the bumper holder is bent preferentially in the direction away from the lamp, and the transmission of the impact load applied to the bumper to the lamp is suppressed, making the lamp effective from the impact. Can be protected.

The fixing portion 1a of the side portion 1C of the bumper holder 1 is fixed to the hood lock member 22 together with the housing 20A of the headlamp 20 by screwing into a welding nut 25 welded to the lower surface of the foot lock member 22.

  Next, the effect | action at the time of the vehicle collision of the bumper holder 1 which concerns on this invention is demonstrated based on FIGS. 12 to 15 are sectional views taken along the line GG of FIG. 6, and FIG. 16 is a sectional view taken along the line HH of FIG.

  Before the vehicle collision, as shown in FIG. 12, a gap δ1 in the vehicle front-rear direction is formed between the flange 21a of the front bumper 21 in the locking portion 5 of the bumper holder 1, and the lamp mounting hole of the bumper holder 1 is formed. 9, a gap δ2 in the vehicle front-rear direction is formed between the clip 4 and the clip 4.

  When an impact from the front of the vehicle is applied to the front bumper 21 due to a frontal collision of the vehicle from the state shown in FIG. 12, the impact is absorbed by the following three steps depending on the magnitude of the impact. It is possible to prevent the lamp from being damaged.

1) First stage:
When the impact applied to the front bumper 21 is relatively small and the amount of movement of the front bumper 21 toward the rear of the vehicle is within the range of the clearance δ1 formed in the locking portion 5 of the bumper holder 1 in the vehicle front-rear direction, As shown in FIG. 13, only the front bumper 21 moves to the rear of the vehicle, and the impact energy is absorbed by the movement (elastic deformation), and the impact is not transmitted to the bumper holder 1 or the headlamp 20. It is. When the impact is slight, the resin-made front bumper 21 returns to its original shape, so that the front bumper 21 returns to its original position before the collision, and the locking portion 5 of the bumper holder 1 is in the vehicle front-rear direction. A gap δ1 is secured.

2) Second stage:
When an impact larger than that in the first stage is applied to the front bumper 21, the front bumper 21 moves rearward as shown in FIG. 14, and the flange 21a pushes the locking portion 5 of the bumper holder 1, so that the bumper holder 1 moves to the rear of the vehicle. Here, since the lamp mounting holes 9 are formed in the brackets 7 and 8 of the bumper holder 1 so as to be long in the vehicle front-rear direction, the vehicle front-rear direction formed between the lamp mounting holes 9 and the clip 4 is formed. The bumper holder 1 is allowed to move within the gap δ2. At this time, the position of the clip 4 does not change, but the clip 4 is disengaged from the positioning hole 9a of the lamp mounting hole 9 and slides relatively to the escape hole 9b.

  Thus, in this second stage, the bumper holder 1 moves relative to the headlamp 20, and the impact applied from the front bumper 21 to the bumper holder 1 is not transmitted to the headlamp 20 side. Damage to 1 itself is also prevented. Also in this case, since the resin front bumper 21 returns to its original shape, the front bumper 21 returns to its original position before the collision, and the gap (parting) between the front bumper 21 and the headlamp 20 is kept constant. Be drunk.

3) Third stage:
When a larger impact load is applied to the front bumper 21 than in the second stage, the relief hole 9b of the lamp mounting hole 9 formed in the bumper holder 1 presses the clip 4 as shown in FIG. 4 breaks or falls off. Then, since the bumper holder 1 and the headlamp 20 are completely separated from each other, an impact load is not applied to the headlamp 20 and the damage is prevented.

  By the way, in the present embodiment, as described above, the bent portion 1B of the bumper holder 1 is arranged in front of the vehicle with respect to the fixing portions 1a and 2b, and the side portion 1C of the bumper holder 1 is inclined obliquely upward toward the rear of the vehicle. 16, when an impact is applied to the front bumper 21 from the front of the vehicle at the time of a vehicle collision as shown in FIG. 16, a reaction force of the side portion 1C fixed by the fixing portion 1a is generated, and the bumper holder 1 is inclined. A downward force F acts. For this reason, the side part 1C rotates around the fixing part 1a, the lower part 1A of the bumper holder 1 moves obliquely downward, and the front bumper 21 can be guided downward, which is the direction away from the headlamp 20, This prevents the front bumper 21 from colliding with the headlamp 20 and prevents the headlamp 20 from being damaged.

  Further, in the present embodiment, the fixing portion 1a formed at the upper end of the side portion 1C of the bumper holder 1 is constituted by a substantially horizontal plane, and the fixing portion formed at the end portion of the vertical wall portion 1D of the bumper holder 1 Since the 1b is fixed to the vehicle body frame 23 by the bolt 3 in the vehicle width direction, the bumper holder 1 is preferentially bent away from the headlamp 20 when the front bumper 21 is moved, and the impact load applied to the front bumper 21 is increased. Transmission to the headlamp 20 can be suppressed and the headlamp 20 can be effectively protected from impact.

  And in this Embodiment, since the structure which inserts and latches the flange 21a formed in the upper edge of the front bumper 21 in the latching | locking part 5 formed in the lower part 1A of the bumper holder 1 was employ | adopted, it is fixed to the bumper holder 1. In addition, a highly accurate positional relationship is ensured between the headlamp 20 and the front bumper 21, and a gap (parting) between the two is kept constant, so that an appearance can be improved.

  The bumper holder disposed on the periphery of the left headlamp has been described above. However, a similar bumper holder is provided on the periphery of the right headlamp, and this bumper holder performs the same function. Further, the above description has been given of the bumper holder disposed at the periphery of the headlamp provided at the front of the vehicle. However, the same effect as described above can be obtained by disposing a similar bumper holder at the periphery of the rear combination lamp provided at the rear of the vehicle. Of course, it can be obtained.
