OVERVIEW OF THE INVENTION

TASKS TO BE SOLVED BY THE INVENTION

In the vehicle front part here is the possibility of reducing the collision load, d. H. a load-bearing capacity, desired to reduce a load applied to a colliding object in a collision. Patent Document 1, on the other hand, deals with the damage of the detecting device and therefore does not mention the load bearing ability in a collision. For this reason, in order to further improve the safety, an improvement of the structure for mounting the radar device of Patent Document 1 has been demanded.

In view of the above-mentioned problem, an object of the present invention is to provide an attachment structure for a detection device capable of increasing a load bearing ability in a collision when a detection device is mounted on a vehicle front part, and a force acting on a colliding object Reduce load.

MEANS TO SOLVE THE TASK

The object is achieved by a representative embodiment of a recognition device attachment structure according to the invention, which is used for attaching a recognition device, which detects an object in the vicinity of the vehicle, to a vehicle front part and comprises: a first structural element arranged in a front part of an engine compartment in FIG Vehicle transverse direction, a second structural element which extends in the front part of the engine compartment below the first structural element in the vehicle transverse direction, and a first holder, on which the detection device is mounted, wherein the first holder is fixed to the first and the second structural element and comprises: a plate-shaped attachment portion disposed between the first structural member and the second structural member and in front of the first structural member and the second structural member, the recognition device being attached to a front surface of the attachment portion; an upper fixing portion extending from an upper edge of the attachment portion further up to a vehicle rear side, the upper fixing portion being fixed to the first structural member; and a lower fixing portion further downward from a lower edge of the attachment portion toward the vehicle rear side extends, wherein the lower fixing portion is fixed to the second structural element.

In the structure described above, when a colliding object collides, the first bracket is deformed so as to move toward the vehicle rear side due to a load applied thereto by the detection device. Since the load can be absorbed by this deformation, the load bearing capacity in a collision can be increased and the load applied to the colliding object can be reduced.

The first holder preferably has a fracture-sensitive portion whose rigidity is lower than that in its vicinity, the fracture-sensitive portion being provided at a boundary between the attachment portion and the upper fixing portion. In this configuration, the upper fixing portion of the first bracket deforms easier than the lower fixing portion. For this reason, when a load is applied, the upper fixing portion deforms so as to face the vehicle rear side, and the detection apparatus attached to the attachment portion assumes a position in which it faces upward. Consequently, it is possible to prevent a false trigger, which would likely occur if the recognition device were to point downwards due to a collision.

The upper fixing section, when viewed in a side view, preferably runs in a straight line between the attachment section and the first structural element, the lower fixing section when viewed in a side view straight between the attachment portion and the second structural member and a straight-running portion at the upper fixing portion is longer than in the lower fixing portion. This embodiment can also favor the deformation of the upper fixing section in the event of a collision. Accordingly, the above-mentioned effect can be enhanced.

This attachment structure for a recognition device may further include: a second bracket disposed between the first bracket and the recognition device, and a decorative element disposed farther than the recognition device and forming an outer side in a vehicle front part, the second bracket having a contact portion that contacts the attachment portion and a protruding portion that extends from an upper end of the contact portion above the recognition device, and wherein the recognition device attachment structure has a facing portion formed in a rear surface of the decorative member that faces the projecting portion Section facing. In this configuration, the facing portion which has moved toward the vehicle rear side due to a load pushes the protruding portion inward toward the vehicle rear side. Consequently, the deformation of the upper fixing portion can be further promoted and, accordingly, the above-mentioned effect can be further enhanced.

EFFECT OF THE INVENTION

According to the present invention, it is possible to provide a mounting structure for a detection device capable of increasing a load bearing ability in a collision when a detection device is mounted on a vehicle front part, and to reduce a load applied to the colliding object.
