Description

The present invention relates to a support structure for a bumper around a ramp of a vehicle.
In particular, the present invention relates to a structure for managing a mutual position having a gap with a bumper by a holder provided around a lamp.

In a bumper attached to a vehicle, for example, a front portion of the vehicle, the bumper is made of a soft material because of required performance such as energy absorption and resilience to a slight external force.
In addition, the bumper is large in size and also has components such as fog lamps mounted thereon, and therefore is easily deformed depending on the weight of the bumper itself and the weight of components such as the fog lamp mounted on the bumper.

Japanese Patent No. 4029379

By the way, in the conventional bumper described above, there is a problem that it is difficult to match the shape of the bumper and the adjacent headlamp, and the appearance is deteriorated due to the positional deviation.
In order to solve this problem, a holder for adjusting the gap (also referred to as “bumper holder”) is set, but the conventional holder has the following disadvantages.
(1) When the lens structure of the headlamp is integrated (FIG. 6), the watertightness of the headlamp deteriorates due to the load due to the weight of the bumper, and mechanical fastening such as screw fixing is necessary as a countermeasure.
(2) When the holder is set only on the lower side of the headlamp, there remains a problem of displacement in the vehicle width direction.
(3) When the structure is such that the holder is not fixed to the headlamp, the positional deviation between the headlamp and the holder remains, so the problem of positional deviation between the bumper and the headlamp remains.

In addition, there is a holder (also referred to as “lean force”) provided on the lower side of the headlamp as disclosed in Patent Document 1 described above.
In this structure, the distance between the lower side of the headlamp is short, that is, the dimension from the inner side of the headlamp to the front fender is small, and the upper cross member and the front fender are directly connected.
Since the bumper does not have a rising portion like the radiator grill, it is sufficient to consider the lower side only for the parting between the bumper and the headlamp.
For this reason, when a headlamp having a high designability and a bumper integrated with a radiator grill having a high designability are assembled to a wider vehicle having a wider width, the gap management for the parting is insufficient.
In addition, in a large-sized headlamp that is a fitting, it is necessary to inevitably increase the mounting rigidity (which can also be referred to as “support rigidity”).

  The present invention provides a holder with less load applied to the headlamp, thereby ensuring the watertightness of the headlamp body, and managing the mutual position of the headlamp and the bumper in the vertical and horizontal directions. An object of the present invention is to provide a structure, to allow a headlamp and a holder to be supported by a bumper independently to some extent while managing the mutual position, and to secure a degree of freedom in mounting a headlamp having an excellent appearance.

  Accordingly, in order to eliminate the above-described disadvantages, the present invention provides a vehicle front portion in which a bumper is provided along a part of the outer edge of a vehicle headlamp, and a holder for holding the positioning or outer shape of the bumper is provided. In the mounting component mounting structure, the holder is provided separately from the headlamp, the holder has a bend, and has a shape connecting two sides of the headlamp and the lower side of the headlamp. It is characterized by doing.

As described above in detail, according to the present invention, a bumper is disposed along a part of the outer edge of the headlamp of the vehicle, and a vehicular front mounting part provided with a holder for holding the positioning or outer shape of the bumper. In the mounting structure, a holder is provided separately from the headlamp, and the holder is bent and has a shape connecting the two sides of the headlamp and the lower side of the headlamp.
Accordingly, the mutual gap between the bumper and the headlamp can be managed small for a long distance extending from the inner side of the headlamp to the lower side of the headlamp.
