DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front body structure of a vehicle provided with a pair of front frames (front side frames) extending in the front-rear direction of the vehicle on the left and right sides of the front of the vehicle.

[0002]

2. Description of the Related Art Conventionally, a pedestrian protection is provided on a front portion of a vehicle body (a pedestrian leaning toward a vehicle side is put on an upper portion of a hood when a pedestrian leans on the vehicle side when a collision between the vehicle and the pedestrian occurs). Front cross member (so-called No. 1) to secure front body rigidity.
Cross member) or bumper reinforcement is attached.

The above-mentioned front end lower member is mounted on a pair of left and right front side frames via brackets, which complicates the mounting structure of the front end lower member and ensures a sufficient degree of freedom in shape and rigidity. There was a problem that could not be done.

The above-mentioned front cross member and bumper reinforcement are separately formed, a bumper reinforcement is mounted on a front portion of a front side frame, and a front cross member is mounted on a lower position of the front side frame. As a result, there is a problem that the mounting structure of both of them (the front cross member and the bumper reinforcement) becomes complicated, and it is not possible to secure a sufficient degree of freedom in shape and rigidity.

On the other hand, JP-A-10-218017 and JP-A-11-235963 disclose a configuration in which a hydroform molded part is used as a reinforcing member of a vehicle body.

That is, the former JP-A-10-218017
Japanese Patent Application Laid-Open No. H11-111699 discloses a structure in which a reinforcing member formed by hydroforming is disposed inside a closed cross section between a center pillar outer and a center pillar inner.
Japanese Patent Publication No. 235963 discloses a structure in which a reinforcing member formed by hydroforming is disposed inside a closed cross section between a rocker panel and a floor side panel constituting a cabside front frame.

[0007]

When the reinforcing member formed by hydroforming is disposed inside a closed cross section as described above, the rigidity of the vehicle body is improved, but the number of parts is increased and the number of assembly steps is reduced. In addition, there has been a problem that weight reduction is hindered.

According to the present invention, a tubular front end lower member whose both ends are connected to the front frame and extends in the vehicle width direction and whose central portion is located forward of the front frame connecting portion is provided, so that the pedestrian can be protected. Attach the front end lower member to the mounting part (that is, the front frame connection part)
Front part of a vehicle that can be configured with a tubular member that is integral with the vehicle, can improve the degree of freedom in shape and rigidity while simplifying the mounting structure, and can achieve further weight reduction. The purpose is to provide the body structure.

The present invention also provides a front cross member and a bumper reinforcement by providing a tubular cross member member extending in the vehicle width direction between a pair of left and right front frames and also serving as a front cross member and a bumper reinforcement. Can be constituted by a single tubular member, the degree of freedom in shape and rigidity can be improved while simplifying the mounting structure, and the front body of the vehicle can be reduced in weight. The purpose is to provide the structure.

Therefore, a predetermined portion of the front end lower member 20 (refer to the protruding portion 20b) is located ahead of the front cross member 6, and when a collision between the vehicle and the pedestrian occurs, The pedestrian who leans toward the vehicle is placed on the upper part of the bonnet 1 by surely paying his / her feet, so that the pedestrian's secondary obstacle can be reliably prevented.

Further, the front end lower member 2
Reference numeral 0 denotes a tubular member having a small diameter at a central portion with respect to a connection portion with the front side frame 5 (see the attachment portion 20a) and having a continuously changing size.

According to this configuration, the front end lower member 20 has a small diameter at its central portion, a continuously changing size, and a step-free shape, so that pedestrian protection is further reliably and safely performed. .

In addition, the front end lower member 2
The two end portions (see the attachment portion 20a) of the O are integrally formed in a flat plate shape, and the flat plate portion is attached to a side surface of the front side frame 5.

According to this configuration, since both ends of the front end lower member 20, that is, the mounting portions 20 a for the front side frame 5 are formed integrally and in a flat plate shape, the number of assembling steps and the number of parts are reduced, and the mountability is improved. Can be improved.

The installation height of the tubular front end lower member 20 is set at a height corresponding to a position below the knee of the pedestrian. Thus, the height position of the front end lower member 20 (specifically, the protrusion 2
(Height position of 00b) is set to an optimum height for walking the foot of the pedestrian, so that a better foot sweep can be performed at the time of collision between the vehicle and the pedestrian.

Further, the tubular front end lower member 20 is constituted by a tubular member integrally formed by a tube hydroform. As described above, by forming the front end lower member 20 by the tube hydroform, the cross-sectional shape, the plate thickness, and the strength can be freely and arbitrarily set, so that so-called tuning can be facilitated and the weight can be reduced. be able to.
