Problems to be solved by the invention

[0003] In a vehicle, the collision energy is generally absorbed by the side members being destroyed during a collision from the front, and the collision energy is concentrated on the side members. Tend. In this case, there is a limit to the absorption of the collision energy by the side members, so it is necessary to make the structure so that the collision energy is not concentrated on the side members as much as possible.

According to the structure of Patent Document 1, apart from the side members (12 in FIGS. 1 and 2 of Patent Document 1), a skeletal member (16 in FIGS. 1 and 2 of Patent Document 1) is provided. As a result, the collision energy is applied not only to the side members but also to the skeletal members. However, since the side members and the skeletal member are located away from each other, There is room for improvement in that the energy is applied to the skeletal members instead of the strength if the side members are strong.

An object of the present invention is to provide a front structure of a vehicle that can avoid a state in which energy of a collision is intensively applied to a side member at the time of a frontal collision. The purpose is to prevent the energy of the collision from being concentrated on another vehicle part in the event of a frontal collision.

Means for solving the problem

[0005] A first characteristic configuration of the present invention resides in that a front structure of a vehicle is configured as follows.

That is, the vehicle includes a side member disposed on the right and left sides of the front part of the vehicle body along the front-rear direction of the vehicle body, and a cross member disposed on the front part of the vehicle body along the left-right direction of the vehicle body. An apron section that forms a front wheel tire house above the side members, and a connecting member that is connected to the apron section and extends downward. The front of the side member is connected so that the front of the front of the side member, the front of the side of the cross member, and the front of the lower part of the connecting member are connected to each other at approximately the same position in the vehicle longitudinal direction and are substantially flush Part and cross member The one side part and the lower part of the connecting member are connected to each other.

According to the first characteristic configuration of the present invention, the front part of the side member, the lateral part of the cross member, and the lower part of the connecting member are connected to each other, and the front part of the front part of the side member and the lateral part of the cross member are connected. The front part and the front part of the lower part of the connecting member are connected to each other at substantially the same position in the longitudinal direction of the vehicle body so as to be substantially flush with each other, so that the front part of the front part of the side member and the lateral part of the cross member And the front of the lower part of the connecting member form a relatively wide and large receiving surface.

[0007] With this, at the time of a collision from the front, the collision energy is applied to the front front surface of the side member, the front surface of the lateral portion of the cross member, and the front surface of the lower portion of the connecting member at substantially the same moment. In addition, they can be spread over a relatively wide range. Therefore, the energy of the collision can be distributed and applied to the cross member and the left and right connecting members which are not powered by the side members. As a result, the energy of the collision is concentrated on the side members Can be avoided, and the function of absorbing collision energy can be enhanced.

[0008] Further, since an apron portion that forms a front wheel tire house is provided above the side member, and the connecting member is connected to the apron portion, as described above, the energy of the collision is applied to each portion of the connecting member. In addition to dispersing the collision energy, the collision energy can also be applied to the apron section via the connecting member 1, so that the collision energy can be absorbed also in the apron section.

[0009] Furthermore, the front surface of the front portion of the side member, the front surface of the lateral portion of the cross member, and the front surface of the lower portion of the connecting member form a receiving surface having a relatively large area. In the event of a collision from a vehicle, the energy of the collision is applied to another vehicle via the receiving surface having a large area and the area described above, and the energy of the collision can be dispersed. For example, the energy of the collision is concentrated on the part of another vehicle from the front of the side member, so that the side member can be prevented from entering the part of another vehicle.

[0010] A second characteristic configuration of the present invention is that, in the front structure of the vehicle, a concave portion is formed in the front portion of the side member or the lateral portion of the cross member so that the lateral portion of the cross member is formed in the concave portion in the front portion of the side member. Part or the front part of the side member is inserted into the concave part of the side part of the cross member so that the front part of the side member and the side part of the cross member partially overlap in front view. It connects the front of the member and the side of the cross member.

According to the second characteristic configuration of the present invention, since the front portion of the side member and the lateral portion of the cross member are connected so as to enter the recess, the front portion of the side member and the lateral portion of the cross member are connected. Are firmly connected to each other. Therefore, in the event of a collision from the front, the energy of the collision can be reliably applied to the left and right side members and the cross member. Therefore, the function of absorbing collision energy can be enhanced.

[0012] A third characteristic configuration of the present invention is that, in the front structure of the vehicle, a concave portion is formed in a front portion of the side member or a lower portion of the connecting member, so that a lower portion of the connecting member is formed in the concave portion of the front portion of the side member. The front of the side member and the lower part of the connecting member in front view. The point is to connect the front part of the side member and the lower part of the connecting member so that they overlap.

[0013] According to the third characteristic configuration of the present invention, since the front part of the side member and the lower part of the connecting member are connected so as to enter the concave part, the front part of the side member and the lower part of the connecting member are connected. They are firmly connected to each other. For this reason, in the event of a collision from the front, the energy of the collision is reduced by the left and right side members and the left and right connecting members with respect to the front front of the side members, the front side of the cross member, and the front of the lower portion of the connecting member. To ensure that it is engaged. Therefore, the ability to absorb the energy of the collision can be increased.

[0014] A fourth characteristic configuration of the present invention is that the convex portion for determining the connecting position of the cross member and the connecting member with respect to the side member and for maintaining the flatness of the same surface, A connecting member having a mounting plane is mounted on the front front surface of the side member.

[0015] According to a fourth feature configuration of the present invention, a convex portion for determining the position of the cross member and the connecting member with respect to the side member and maintaining the flatness of the same surface, and a mounting surface to the side member. Is attached to the front surface of the front side of the side member. Thereby, at the time of connection, positioning of the cross member 1 and the connection member with respect to the side member is ensured. As a result, the cross member and the connecting member can be securely attached to the side members at predetermined positions, so that the members can be firmly connected. In the event of a forward collision, the energy of the collision is applied to the front of the front of the side member, the front of the side of the cross member, and the front of the lower part of the connecting member at about the same moment and relatively wide. Since it can be spread over the range, the function of absorbing collision energy can be enhanced.

[0016] At least any two members of the side member, the cross member, and the connection member are bolted together, and a head portion of the bolt is retreated toward the side member from the same surface. On the point.

According to the fifth characteristic configuration of the present invention, at least any two members of the side member, the cross member, and the connecting member are connected by bolts. Therefore, with the side members The cross member and the connecting member are firmly connected, and the energy of the collision can be reliably applied to the left and right side members, the cross member, and the left and right connecting members. Also, since the head portion of the bolt is retracted closer to the side member than the same surface, the head portion of the bolt is not particularly connected to the connecting portion by protruding, so it is concentrated on a part of the connecting portion. As a result, the energy of the collision will not be strong. As a result, the function of absorbing collision energy can be further enhanced. BEST MODE FOR CARRYING OUT THE INVENTION
