Abstract

A vehicle bumper includes: a bumper beam, a bumper face, covering a vehicle body front surface of the bumper beam, and a buffer component, provided between the bumper beam and the bumper face. The buffer component includes a platelike component configured to be folded upon collision load. The buffer component includes a folded part, and two surface parts that are connected through the folded part and are opposite to each other with a gap therebetween in a front-rear direction of the vehicle. A pressure pipe configured to be deformed by being clamped between the two surface parts so as to detect impact is provided in the gap. A lower space part that avoids interference between the bumper beam and a setting part for the pressure pipe in the buffer component is provided below the bumper beam.

First claim

What is claimed is:

1. A vehicle bumper, configured to mitigate impact on a collided object when collision between the vehicle bumper and the collided object occurs, the vehicle bumper comprising:
a bumper beam, extending along a vehicle width direction;
a bumper face, covering a vehicle body front surface or a vehicle body rear surface that comprises the bumper beam; and
a buffer component, provided between the bumper beam and the bumper face, wherein
the bumper beam comprises a front surface part that becomes a collision surface, and at least one of an upper surface part connected to an upper end part of the front surface part and a lower surface part connected to a lower end part of the front surface part;
the buffer component comprises a platelike component configured to be folded upon collision load;
the buffer component comprises at least one folded part, and at least two surface parts that are connected through the folded part and are opposite to each other with a gap therebetween in a front-rear direction of the vehicle;
a pressure pipe configured to be deformed by being clamped between the two surface parts so as to detect impact is provided in the gap; and
a space part configured to avoid interference between the bumper beam and a setting part for the pressure pipe in the buffer component during collision is provided.

2. The vehicle bumper according to claim 1 , wherein
an upper space part located at an upper location relative to the upper surface part or a lower space part located at a lower location relative to the lower surface part forms the space part; and
the pressure pipe is disposed with an offset in a height direction relative to the front surface part of the bumper beam.

3. The vehicle bumper according to claim 1 , wherein
a cut part formed by cutting a part of the front surface part towards a rear side of a collision direction is provided in the bumper beam;
the cut part forms the space part; and
the pressure pipe is disposed at a height location the same as that of the cut part.

4. The vehicle bumper according to claim 1 , wherein
a recess formed by recessing a part of the front surface part towards a rear side of a collision direction is provided in the bumper beam;
the recess forms the space part; and
the pressure pipe is disposed at a height location the same as that of the recess.

5. The vehicle bumper according to claim 2 , wherein
a bent part that becomes a base point upon which the buffer component is bent is formed on an end part, located on a side opposite to the folded part, of the surface part located in a rear part of the vehicle, and
a distance from the bent part to a peripheral surface of the pressure pipe on a side of the bent part is set to be greater than a distance from the bent part to an end part of the front surface part on a side of the space part.

6. The vehicle bumper according to claim 3 , wherein
a bent part that becomes a base point upon which the buffer component is bent is formed on an end part, located on a side opposite to the folded part, of the surface part located in a rear part of the vehicle, and
a distance from the bent part to a peripheral surface of the pressure pipe on a side of the bent part is set to be greater than a distance from the bent part to an end part of the front surface part on a side of the space part.

7. The vehicle bumper according to claim 4 , wherein
a bent part that becomes a base point upon which the buffer component is bent is formed on an end part, located on a side opposite to the folded part, of the surface part located in a rear part of the vehicle, and
a distance from the bent part to a peripheral surface of the pressure pipe on a side of the bent part is set to be greater than a distance from the bent part to an end part of the front surface part on a side of the space part.
