Description

The present invention relates to a front structure of a vehicle, for example, in which a shock absorbing member for absorbing a shock load from the front side of the vehicle is provided in the front of the vehicle.

When a colliding object collides with the front part of a vehicle, a vehicle such as an automobile absorbs an impact load acting on the front part of the vehicle due to the collision by an impact absorbing member provided at the front part of the vehicle.
For example, Patent Document 1 discloses a front structure of a vehicle in which an impact load applied to a bumper face upper (upper facer) is absorbed by a reinforcing member whose rear portion has low rigidity with respect to the front portion. As a result, Patent Document 1 suppresses the impact load acting on the colliding object and reduces the damage caused to the colliding object.

In such a front structure of a vehicle, in order to further reduce damage to a colliding object, it is necessary to increase the amount of impact load absorbed by the front of the vehicle. Therefore, for example, it is conceivable to arrange an impact absorbing member for absorbing the impact load from the front side of the vehicle so as to extend in the vehicle width direction inside the bumper face below the upper grill. At this time, the shock absorbing member is preferably composed of a single member instead of a plurality of members from the viewpoint of reducing the number of parts.

However, the bumper face is often provided with, for example, a sensor that detects a vehicle traveling in front of the vehicle, a sensor that detects a distance from an obstacle in front of the vehicle, and the like. Therefore, in order to dispose the shock absorbing member composed of a single member extending in the vehicle width direction inside the bumper face, it is necessary to provide the shock absorbing member with an opening for avoiding interference with the sensor. was there.

However, when the shock absorbing member is provided with the opening, the strength in the vicinity of the opening is lower than the strength around the opening, so that the shock absorbing member may not exhibit the desired shock absorbing performance.

Japanese Unexamined Patent Publication No. 2019-38497

In view of the above problems, it is an object of the present invention to provide a front structure of a vehicle in which a decrease in strength of a shock absorbing member due to the provision of an opening can be suppressed.

The present invention is a front structure of a vehicle provided with a shock absorbing member for absorbing a shock load from the front side of the vehicle behind a bumper face arranged in the front of the vehicle. The lower part of the upper grill provided on the upper part of the bumper face is extended to at least one of a member main body having a main body front portion extending in the vehicle width direction and the upper part of the vehicle and the lower part of the vehicle with respect to the member main body. The member main body is provided with an opening opened in the front surface portion of the main body at a predetermined position in the vehicle width direction, and the mounting portion is provided with an opening in substantially the same vehicle width direction as the opening. It is characterized by being formed at the position of.

According to the present invention, the rigidity in the vicinity of the opening can be improved by the mounting portion. Therefore, the front structure of the vehicle can suppress a decrease in strength in the vicinity of the opening as compared with the case where the mounting portion is formed at a position in the vehicle width direction different from the opening.
Therefore, in the front structure of the vehicle, it is possible to suppress a decrease in strength of the shock absorbing member due to the provision of the opening by the mounting portion provided at a position substantially the same as the opening in the vehicle width direction.

As an aspect of the present invention, the shock absorbing member includes a lower mounting portion, which is a mounting portion extending downward from the member body, and a mounting portion extending upward from the member body.

According to this configuration, the front structure of the vehicle provides a space for arranging the sensor by the receding surface portion and the opening even when the front surface portion of the main body of the shock absorbing member and the bumper face are close to each other. Can be secured.

Further, even when the sensor starts to move to the rear of the vehicle due to the collision between the front part of the vehicle and the colliding object, the front structure of the vehicle allows the sensor to come into contact with the shock absorbing member by the rearward surface portion and the opening. Can be prevented. Therefore, the front structure of the vehicle can prevent damage to the sensor and unintended malfunction due to contact with the sensor on the shock absorbing member.

Further, as an aspect of the present invention, the sensor includes a connector portion protruding in one direction in the vehicle width direction, and the opening straddles the front surface portion of the main body adjacent to the retracting surface portion on one side in the vehicle width direction. The opening may be formed.

According to this configuration, the front structure of the vehicle can secure a large opening area of the opening, while reducing the area of the retracted surface portion. Therefore, the front structure of the vehicle can secure the area of the front surface of the main body, and the impact load from the front side of the vehicle can be stably received by the front surface of the main body.

Further, since the opening is opened so as to straddle the retreating surface portion and the adjacent main body front surface portion, the front structure of the vehicle can form an opening in the portion connecting the retreating surface portion and the main body front surface portion. Therefore, in the front structure of the vehicle, a space for connecting the wire harness to the connector portion of the sensor from one side in the vehicle width direction is provided by an opening that is opened across the rear portion and the adjacent front portion of the main body. Can be secured.
As a result, the front structure of the vehicle can suppress the deterioration of the shock absorption performance of the shock absorbing member and improve the assembling property of the front part of the vehicle.

Further, as an aspect of the present invention, the shock absorbing member connects the front surface portion of the main body adjacent to the retracting surface portion on one side in the vehicle width direction and the edge edge of the mounting portion in the vehicle width direction. A reinforcing portion may be provided.

According to this configuration, in the front structure of the vehicle, the connecting portion between the front surface portion of the main body and the mounting portion can be reinforced by the reinforcing portion. Therefore, in the front structure of the vehicle, the decrease in rigidity of the front surface portion of the main body due to the provision of the opening can be suppressed by the reinforcing portion. As a result, the front structure of the vehicle can suppress a decrease in strength of the shock absorbing member even when a large opening area of the opening is secured.
