Abstract

A fuel pipe protective structure includes a fuel pipe, a connecting member, and a protective member. The protective member is to protect a connection between the fuel pipe and the connecting member. The protective member includes a base and a cover. The base is to be connected to a vehicle body wall that defines an engine compartment. The cover is to be interposed between the connection and an internal combustion engine so as to cover the connection. The cover includes a guide. The guide is configured to cause the protective member to be plastically deformed in order to displace the connection in a receding direction in which the connection moves to avoid being caught by the internal combustion engine in a case where the internal combustion engine moves toward a vehicle interior upon collision of the vehicle.

First claim

What is claimed is:

1. A fuel pipe protective structure comprising:
a fuel pipe having a first end connected to an internal combustion engine mounted in an engine compartment of a vehicle and a second end disposed closer to a vehicle interior than the internal combustion engine in a direction from a front of the vehicle to a rear of the vehicle;
a connecting member connected to the second end of the fuel pipe; and
a protective member that protects a connection between the fuel pipe and the connecting member,
the protective member including
a base fixed to a vehicle body wall that defines the engine compartment, and
a cover interposed between the connection and the internal combustion engine so as to cover the connection,
the cover including
a guide that is configured to cause the protective member to be plastically deformed in order to displace the connection in a receding direction in which the connection recedes to avoid being caught by the internal combustion engine when the internal combustion engine moves toward the vehicle interior upon collision of the vehicle,

wherein the connection is disposed between the base and the cover of the protective member in the direction from the front of the vehicle to the rear of the vehicle.

2. The protective structure according to claim 1 , wherein the guide includes
a sloping wall that is at least part of the cover extending outwardly so as to extend gradually away from the vehicle body wall in the receding direction, and
a curved part formed by curving part of the cover facing in a direction opposite to the receding direction.

3. The fuel pipe protective structure according to claim 1 , wherein the cover is secured to the base by a plurality of fasteners and at least one of the fasteners is disposed on an opposite side of a section of the base fixed to the vehicle body wall from part of the base extending in the receding direction.

4. The fuel pipe protective structure according to claim 3 , wherein the base includes a support that supports the fuel pipe and the support is disposed adjacent to the part of the base extending in the receding direction relative to the section of the base fixed to the vehicle body wall.

5. The fuel pipe protective structure according to claim 1 , wherein the cover has a U-shaped cross section, and the connection is disposed in a central portion of the U-shaped cross section that faces the base in the direction from the front of the vehicle to the rear of the vehicle.

6. The fuel pipe protective structure according to claim 1 , wherein the base is directly fixed to the vehicle body wall.

7. The fuel pipe protective structure according to claim 1 , wherein the connection and the protective member are disposed behind the internal combustion engine in the direction from the front of the vehicle to the rear of the vehicle.

8. A fuel pipe protective structure comprising:
a fuel pipe having a first end to be connected to an internal combustion engine mounted in an engine compartment of a vehicle and a second end disposed closer to a vehicle interior than the internal combustion engine in a direction from a front of the vehicle to a rear of the vehicle;
a connecting member connected to the second end of the fuel pipe; and
a protective member to protect a connection between the fuel pipe and the connecting member, the protective member comprising:
a base to be connected to a vehicle body wall that defines the engine compartment; and
a cover to be interposed between the connection and the internal combustion engine so as to cover the connection, the cover comprising:
a guide configured to cause the protective member to be plastically deformed in order to displace the connection in a receding direction in which the connection moves to avoid being caught by the internal combustion engine in a case where the internal combustion engine moves toward the vehicle interior upon collision of the vehicle,

wherein the connection is disposed between the base and the cover of the protective member in the direction from the front of the vehicle to the rear of the vehicle.

9. The protective structure according to claim 8 , wherein the guide includes
a sloping wall comprising at least part of the cover extending outwardly so as to extend gradually away from the vehicle body wall in the receding direction, and
a curved part provided by curving part of the cover facing in a direction opposite to the receding direction.

10. The fuel pipe protective structure according to claim 8 , wherein the cover is secured to the base by a plurality of fasteners and at least one of the plurality of fasteners is disposed on an opposite side of a section of the base connected to the vehicle body wall from part of the base extending in the receding direction.

11. The fuel pipe protective structure according to claim 10 , wherein the base includes a support that supports the fuel pipe and the support is disposed adjacent to the part of the base extending in the receding direction relative to the section of the base connected to the vehicle body wall.

12. The fuel pipe protective structure according to claim 8 , wherein the base is connected to the vehicle body wall by a first fastener, and the cover is connected to the base by second and third fasteners, and
wherein the second fastener is provided at a higher level than the first fastener in a vertical direction, and the third fastener is provided at a lower level than the first fastener in the vertical direction.

13. The fuel pipe protective structure according to claim 8 , wherein the cover has a U-shaped cross section, and the connection is disposed in a central portion of the U-shaped cross section that faces the base in the direction from the front of the vehicle to the rear of the vehicle.

14. The fuel pipe protective structure according to claim 8 , wherein the base is configured to be directly fixed to the vehicle body wall.

15. The fuel pipe protective structure according to claim 8 , wherein the connection and the protective member are configured to be disposed behind the internal combustion engine in the direction from the front of the vehicle to the rear of the vehicle.

16. A vehicle comprising:
an internal combustion engine mounted in an engine compartment;
a vehicle body wall disposed at an outer periphery of the engine compartment;
a vehicle interior disposed behind the engine compartment; and
a fuel pipe protective structure including
a fuel pipe having a first end connected to the internal combustion engine and a second end disposed closer to the vehicle interior than the internal combustion engine;

a connecting member connected to the second end of the fuel pipe; and
a protective member that protects a connection between the fuel pipe and the connecting member,
the protective member including
a base fixed directly to the vehicle body wall, and
a cover interposed between the vehicle body wall and the internal combustion engine so as to cover the connection,

the cover including
a guide that is configured to cause the protective member to be plastically deformed in order to displace the connection in a receding direction in which the connection recedes to avoid being caught by the internal combustion engine when the internal combustion engine moves toward the vehicle interior upon collision of the vehicle.

17. The fuel pipe protective structure according to claim 16 , wherein the cover has a U-shaped cross section, and the connection is disposed in a central portion of the U-shaped cross section that faces the base in a direction from the
