Description

  The present invention relates to a headlamp mounting structure, and more particularly to a headlamp mounting structure that is mounted to a front portion of a vehicle body at a plurality of mounting portions.

  Headlamps attached to the front of the vehicle may receive impact loads from the pedestrian's thighs and head from above when colliding with pedestrians, and during light collisions with other vehicles In addition, an impact load may be received from the front.

  In these cases, it is desirable for the headlamps to absorb their input load. However, a structure that breaks the headlamps themselves and absorbs the load is not preferable because repair costs increase. That is, compatibility between the viewpoint of protecting pedestrians and the repairability of the headlamp at the time of a light collision with another vehicle has arisen as a recent issue.

  Conventionally, in Patent Document 1, an upper coupling portion and a lower coupling portion are provided as means for coupling a headlamp and a vehicle body, and when a collision load from above the vehicle is input to the headlamp, the upper coupling portion is provided. The upper portion of the headlamp is separated from the radiator support by the weak portion (bond release means) provided in the upper joint portion by the weak portion (bond release means), and the connection with the bumper reinforcement of the lower joint portion is maintained. On the other hand, when a collision load from the front-rear direction of the vehicle is input, the connection state between the lower part of the vehicle body and the headlamp is released to suppress the transmission of the collision load applied to the vehicle body to the headlamp. A headlamp mounting structure is disclosed.

  Further, in Patent Document 2, a bracket oriented along a tangential direction of an arc around a rotation fulcrum provided below the headlamp at the top of the headlamp and a thin pin (fragile portion) for holding the bracket. There is disclosed a headlamp mounting structure that can be rotated backward without breaking the headlamp side so that the thin pin is broken by a shearing force from the bracket at the time of a light vehicle collision. .

  However, the headlamp disclosed in Patent Document 1 is low in shock absorption with respect to an input load from above due to its structure, and its upper coupling portion is not configured to be repairable. Further, when a load is applied from the front, such as during a light collision, the headlamp itself is not structured to retreat, and the headlamp itself may be damaged.

  In addition, the structure disclosed in Patent Document 2 is superior in repairability because the headlamp is not destroyed while reducing the impact applied to the obstacle by rotating the headlamp backward, but the thin pin 21 is specified. Therefore, there is a problem that pedestrian protection cannot be sufficiently achieved because only the input load in a specific direction can be dealt with.

Thus, the load from above the vehicle body is absorbed. Then, the mounting bracket 10 moves downward relative to the bolt 18 and the shroud 4. FIG. 14 shows a state in which the bracket breakage deforming portion 20 is broken.

  Next, in the rear outer mounting portion 11, when the headlamp 2 receives an input load from above the vehicle body as shown in FIG. 11, force is applied to the pin member 24 via the mounting bracket 12 and the bracket 12. Then, a force to move downward is applied to the fender slit 22 of the fender 6, and the pin member 24 receives a reaction force from the fender slit 22. In this embodiment, as shown in FIGS. 4 and 15, since the pin groove portion 25 is formed in the pin member 24, the pin groove portion 25 receives a reaction force from the fender slit 22 as shown in FIG. 16. Breaks or deforms to absorb the load. Then, a part of the mounting bracket 12 and the pin member 24 receiving the load moves downward relative to the fender 6. FIG. 16 shows a state where the pin member 24 is broken.

Next, the rear inner mounting portion 13 similarly absorbs the load by breaking or deforming the pin groove portion 25 of the pin member 24, and the mounting bracket 12 and a part of the pin member 24 are attached to the fender 6 (fender slit 22). On the other hand, it moves relatively downward.
When the headlamp 2 receives an input load from above the vehicle body by the front inner mounting portion 9, the rear outer mounting portion 11 and the rear inner mounting portion 13 that operate as described above, the headlamp 2 has two points in FIG. As indicated by the chain line state B, the vehicle moves downward.

  Next, the amount of deformation of the front inner mounting portion 9, the rear outer mounting portion 11 and the rear inner mounting portion 13 varies depending on the location and angle of collision with the headlamp, and the head as in the state C of the two-dot chain line in FIG. The way the lamp moves may be different.

Next, functions and effects of the above-described headlamp mounting structure according to the first embodiment of the present invention will be described.
First, in this embodiment, the mounting bracket 10 of the front inner mounting portion 9 is allowed to move backward relative to the bolt 18 and the shroud 4 when receiving an input load from the front of the vehicle body. The rearward movement of the headlamp 2 integrally formed with the head 10 is allowed, the headlamp 2 is less likely to be damaged, and the front inner mounting portion 9 and thus the repairability of the headlamp 2 can be improved. Further, when the front inner mounting portion 9 receives an input load from above the vehicle body, the mounting bracket 10 itself is deformed and absorbs the load from above, so that the pedestrian's thigh, head, etc. from above The collision load can be absorbed effectively. As a result, it is possible to achieve both the impact absorption of the pedestrian from above the headlamp 2 and the repairability of the headlamp 2 and the front inner mounting portion 9 at the time of a light collision from the front.

  Next, the mounting bracket 10 is provided with a slit portion 16 that is open toward the front of the vehicle body, and the bolt 18 is inserted into the slit portion 16 from the vehicle width direction to attach the mounting bracket 10 to the shroud 4. Therefore, when the headlamp 2 receives an input load from the front of the vehicle body, the slit portion 16 of the mounting bracket 10 passes through the bolt 18 and allows the mounting bracket 10 and the headlamp 2 to move rearward.

  Next, in the front inner mounting portion 9, the slit portion 16 into which the bolt 18 is inserted from the vehicle width direction is opened toward the front of the vehicle body, so that the headlamp 2 moves toward the rear of the vehicle body when a load is input from the front of the vehicle body. Can be tolerated. On the other hand, in the vicinity of the upper portion of the slit portion 16, a bracket breaking deformation portion 20 that is broken or deformed by receiving a reaction force from the bolt 18 is formed. Therefore, when the headlamp 2 receives an input load from above the vehicle body, The bracket fracture deformable portion 20 can break or deform to absorb a load from above.

  Next, since the front inner attachment portion 9 has a bolt 18 extending in the vehicle width direction for attaching the headlamp 2 to the vehicle body, the bolt 18 is slit when a load is input from the front during a collision with another vehicle. It is possible to allow the mounting bracket 10 to move rearward more reliably in cooperation with the portion 16, and in cooperation with the bracket breaking deformation portion 20 when a load is input from above at the time of collision with a pedestrian. The load can be received with certainty.

  Next, the front inner attachment portion 9 is mainly composed of a plate-like attachment bracket 10 provided on the headlamp 2 and a bolt 18, and the slit portion 16 and the bracket breaking deformation portion 20 are composed of the front inner attachment portion 9. Therefore, load absorption and attachment of the front inner attachment portion 9 to the shroud 4 can be performed with a simple configuration.

  Next, in the front inner attachment portion 9, the slit portion 16 and the bracket breakage deformation portion 20 are formed in the plate-like bracket 10, so that load absorption and attachment of the headlamp 2 to the vehicle body are performed with a simple configuration. I can do it. Further, since the bracket 10 is fastened to the vehicle body by the bolts 18, the headlamp 2 can be reliably fixed to the vehicle body.

  The front inner mounting portion 9 is configured such that when the headlamp 2 receives an input load from the front of the vehicle body, the mounting bracket 10 is moved rearward relative to the bolt 18 and the shroud 4 by the slit portion 16. At this time, the mounting bracket 10 is configured to retreat without being deformed by the slit portion 16. However, even if the mounting bracket 10 is slightly deformed, for example, when a load from the front of the vehicle body is input from a slight angle, the mounting bracket 10 is fastened to the vehicle body side with the bolts 18 at the front inner mounting portion 9. Therefore, the next headlamp 2 can be attached and the repairability can be secured. Further, since the mounting bracket 10 is made of resin, it can be returned to its original state if it is slightly deformed.

  Next, since the rear outer mounting portion 11 and the rear inner mounting portion 13 have a pin member 24 extending in the vehicle width direction for mounting the headlamp 2 to the vehicle body, the pin member 24 is at the time of a collision with another vehicle. When a load is input from the front or when a load is input from above during a collision with a pedestrian, the load can be received more reliably.

  Here, since the pin member 24 is inserted into the mounting bracket 12 from the vehicle width direction, the pin member 24 is substantially orthogonal to the input load direction from the front of the vehicle body, and breaks or deforms while absorbing the input load from the front of the vehicle body. It is easy to do. Further, since the pin member 24 is inserted into the fender slit 22 from the vehicle width direction, the pin member 24 is substantially orthogonal to the input load direction from above the vehicle body and breaks or deforms while absorbing the input load from above the vehicle body. It is easy.

  Thus, by providing the bolt 18 and the pin member 24 for attaching the headlamp 2 to the vehicle body so as to extend in the vehicle width direction in the front inner attachment portion 9, the rear outer attachment portion 11 and the rear inner attachment portion 13, A load can be received against a wide range of impacts from the front and top of the vehicle. Thereby, the impact load from above at the time of a pedestrian collision and the impact load from the front at the time of a light collision with another vehicle can be absorbed.

  Next, in the rear outer mounting portion 11 and the rear inner mounting portion 13, when the pin member 24 receives an input load from the front of the vehicle body or an input load from the upper side of the vehicle body, it receives a reaction force from the fender slits 22 and 23, or breaks. Since the pin groove portion 25 is deformed, the pin groove portion 25 is deformed when receiving an input load from the front of the vehicle body or an input load from above the vehicle body, such as at the time of a collision with a pedestrian or a light collision with another vehicle. Can absorb the load. Further, since the pin member 24 is inserted into and engaged with the fender slits 22 and 23 provided on the vehicle body and opened toward the front of the vehicle body, the headlamp 2 can be attached to the vehicle body. Easy.

  Next, in the rear outer mounting portion 11 and the rear inner mounting portion 13, the pin groove portion 25 is formed in the pin member 24, so that when the input load is received from the front and upper sides of the vehicle body, the pin groove portion 25 is It deforms and absorbs the load. Therefore, it is possible to effectively absorb a collision load such as a pedestrian's thigh and head from above, and also to effectively absorb a collision load from the front even during a light collision with another vehicle. I can do it.

  Next, the rear outer mounting portion 11 and the rear inner mounting portion 13 have a pin member 24 that is separate from the mounting bracket 12 for mounting the headlamp 2 to the shroud 4 or the fender 6, and an input load from the front of the vehicle body. When receiving an input load from above the vehicle body, the pin groove portion 25 of the pin member 24 is deformed and absorbs the load from the front and the upper side. Therefore, only the pin member 24 needs to be replaced after the collision. Excellent. In other words, since only the pin member 24 is deformed when subjected to a load, only the pin member 24 needs to be replaced after the collision, so that the repairability is improved.

  Further, the pin member 24 is inserted and engaged from the front of the vehicle body to the fender slits 22 and 23 provided on the fender 6 and opened toward the front of the vehicle body to attach the rear outer mounting portion 11 and the rear inner mounting portion 13 to the fender 6. Thus, the headlamp 2 can be easily attached to the fender 6 or the shroud 4.

  Next, as a function of the positional relationship of the mounting portion, the front inner mounting portion 9 is provided on the front side of the headlamp, and the front inner mounting portion 9 is deformed when receiving an input load from above the vehicle body, Therefore, the headlamp 2 can be reliably repaired and the load absorbing power is excellent. On the other hand, the rear outer mounting portion 11 and the rear inner mounting portion 13 are provided on the rear side and the outer side of the front inner mounting portion 9, so that the front inner mounting portion 9, the rear outer mounting portion 11, and the rear inner mounting portion 13 By cooperating, the headlamp 2 can be stably supported, and the impact load of a pedestrian and the impact load of another vehicle can be stably absorbed.

  Next, the front inner attachment portion 9 is attached to the shroud 4 located on the front side of the vehicle body, and the rear outer attachment portion 11 and the rear inner attachment portion 13 are attached to the fender 6 of the vehicle body, so that the installation space of the headlamp 2 is achieved. Can be secured efficiently.

  Next, since the pin member 24 is engaged with the hole 12a formed in the block-shaped bracket 12, the rear outer mounting portion 11 and the rear inner mounting portion 13 are excellent in repairability and in assembly property. In addition, since the bracket 12 is formed in a block shape, the pin member 24 is also excellent in retainability.

  Next, a headlamp mounting structure according to a second embodiment of the present invention will be described with reference to FIG. FIG. 17 is a plan view of the headlamp mounting structure according to the second embodiment of the present invention as viewed from above the vehicle body. Since the mounting structure of the headlamp according to the second embodiment is substantially the same as the first embodiment described above, only the portions of the second embodiment different from the first embodiment will be described here.

  As shown in FIG. 17, the headlamp 26 according to the second embodiment is different in the shape of the headlamp, and is provided with a first front inner mounting portion 28 at one location on the front side, and behind the first front inner mounting portion 28. In addition, a second rear outer mounting portion 29 and a third rear outer mounting portion 30 are provided side by side at two locations on the outer side in the vehicle width direction. In the shape of the headlamp according to the second embodiment as described above, there is no mounting portion corresponding to the rear inner mounting portion 13 of the first embodiment, so that the mounting of the headlamp 26 becomes unstable. Therefore, in the second embodiment, the headlamp 26 is stably mounted by adopting the following mounting structure.

The first front inner mounting portion 28, the second rear outer mounting portion 29, and the third rear outer mounting portion 30 all have the same structure as the front inner mounting portion 9 of the first embodiment (details are not shown). ), A bolt is inserted from the outside in the vehicle width direction into a mounting slit portion (see reference numerals 20 and 26 in FIG. 3) having a bracket fracture deformed portion, and the mounting bracket is fastened to the shroud or the fender.
Thus, the headlamp 26 can be stably attached by fastening all of the three attachment portions with bolts. The operation at the time of collision of the headlamp mounting structure of the second embodiment (when a load is input from above the vehicle body and when a vehicle body load is input from the front) is the same as the operation of the front inner mounting portion 9 of the first embodiment described above. It is the same.

Next, in the second rear outer mounting portion 29 and the third rear outer mounting portion 30, when the same bolt fixing as the front inner mounting portion 9 similar to the first embodiment is difficult in assembly, it is shown in FIG. It is preferable to adopt the structure of the modified example. FIG. 18 is a partial cross-sectional plan view showing a headlamp mounting structure according to a modification of the second embodiment of the present invention.
As shown in FIG. 18, in the modification of the second embodiment, the tip end portion of the pin 32 of the second rear outer attachment portion 29 is threaded. The pin 32 is inserted into and engaged with a slit (fender slit 22 (see FIG. 4)) formed in the fender 6, and then fixed by a nut 34 from the outside of the fender 6. Further, the pin 32 is formed with a pin groove portion that is broken or deformed when receiving a load input from the front and upper sides of the vehicle body. The structure of the third rear outer attachment portion 30 is also the same.

Thus, by strengthening the attachment of the second rear outer attachment portion 29 and the third rear outer attachment portion 30 with the nut 34, the second rear outer attachment portion 29 and the third rear outer attachment portion 30 are both in the vehicle width direction. Even if it is provided outside, the stability of the headlamp 2 can be improved.
The operations at the time of collision of the headlamp mounting structure according to this modification (at the time of load input from above the vehicle body and at the time of load input from the front of the vehicle body) are the rear outer mounting portion 11 and the rear inner mounting portion of the first embodiment described above. 13, the pin groove portion is broken (see reference numeral 25 in FIG. 4 and the like), and the headlamp is allowed to move backward or downward.
