Abstract
A shock absorbing device according to one embodiment includes an elastic member and an attenuation device. The elastic member is compressed by a force transmitted from the exterior of a vehicle through a front grill which is a vehicle exterior component, and returns the front grill to the vehicle exterior by means of the restoration force against the compression. The attenuation device attenuates the speed of the front grill when the front grill is being returned by the restoration force of the elastic member.
Claims7
A shock absorbing device, comprising:
- an elastic member which is configured to be contracted by a force transferred from a vehicle outside through a vehicle exterior member and to return the vehicle exterior member to the vehicle outside by a restoration force against a contraction of the elastic member, and
- an attenuation device for attenuating a speed when the vehicle exterior member returns by the restoration force, wherein
- the attenuation device includes an air damper forming a first air chamber at one end side of a cylinder with a piston therebetween and a second air chamber at the other end side of the cylinder with the piston therebetween,
- the attenuation device is configured to generate:
- a first attenuation force by limiting an amount of air flowing from the first air chamber to the second air chamber in response to a movement of the piston when the elastic material is contracted by a force from the outside the vehicle, and
- a second attenuation force through a resistance generated by limiting an amount of air flowing from the second air chamber to the first air chamber in response to a movement of the piston when the vehicle exterior member is returned by a restoration force of the elastic member which has been contracted by the force from the outside the vehicle, and
- the first attenuation force is different from the second attenuation force.
A vehicle provided with a shock absorbing device, comprising:
- an elastic member which is configured to be contracted by a force transferred from a vehicle outside through a vehicle exterior member and to return the vehicle exterior member to the vehicle outside by a restoration force against a contraction of the elastic member, and
- an attenuation device for attenuating a speed when the vehicle exterior member returns by the restoration force, wherein
- the attenuation device includes an air damper forming a first air chamber at one end side of a cylinder with a piston therebetween and a second air chamber at the other end side of the cylinder with the piston therebetween,
- the attenuation device is configured to generate:
- a first attenuation force by limiting an amount of air flowing from the first air chamber to the second air chamber in response to a movement of the piston when the elastic material is contracted by a force from the outside the vehicle, and
- a second attenuation force through a resistance generated by limiting an amount of air flowing from the second air chamber to the first air chamber in response to a movement of the piston when the vehicle exterior member is returned by a restoration force of the elastic member which has been contracted by the force from the outside the vehicle, and
- the first attenuation force is different from the second attenuation force.
