Abstract

A damper for a glove box includes a cylinder, a piston movably disposed in the cylinder, and a valve movably disposed in an accommodation portion of the piston. The piston includes a piston body in which an orifice is formed and a rod formed to protrude from the piston body and in which the accommodation portion is disposed. The valve includes a valve body, a pin formed to protrude from the valve body to have an end portion thereof disposed in the orifice, and a leg formed to protrude from the valve body. The valve is configured to move due to movement of the piston in a direction opposite to a movement direction of the piston to have the leg come into contact with the piston body.

First claim

What is claimed is:

1. A damper for a glove box, comprising:
a cylinder;
a piston movably disposed in the cylinder; and
a valve movably disposed in an accommodation portion of the piston,
wherein the piston comprises a piston body in which an orifice is formed and a rod formed to protrude from the piston body and in which the accommodation portion is disposed,
the valve comprises a valve body, a pin formed to protrude from the valve body to have an end portion thereof disposed in the orifice, and a leg formed to protrude from the valve body, and
the valve is configured to move due to movement of the piston in a direction opposite to a movement direction of the piston to have the leg come into contact with the piston body.

2. The damper of claim 1 , wherein:
the piston further comprises a stopper disposed on the rod;
the valve further comprises a hook disposed to correspond to the stopper; and
the hook is formed to protrude from the valve body.

3. A glove box comprising:
a glove box body and a cover forming an accommodation space therebetween; and
the damper of claim 1 ,
wherein the glove box body is rotationally disposed in a dashboard of a vehicle, and
the damper adjusts a movement speed of the glove box body.

4. The damper of claim 2 , wherein:
the stopper comprises a first stopper disposed on a first surface of the rod and a second stopper disposed on a second surface of the rod;
a first separation distance from the piston body to the first stopper is greater than a second separation distance from the piston body to the second stopper; and
a hook portion of the hook is disposed between the piston body and the first stopper or between the piston body and the second stopper.

5. The damper of claim 2 , wherein the piston further comprises a protruding portion formed to protrude from the piston body to allow the orifice to extend.

6. The damper of claim 2 , further comprising a sealing member disposed on an outer side surface of the piston body.

7. The damper of claim 2 , wherein:
the rod comprises a first surface and a second surface opposite to the first surface; and
a recognition part is disposed on the first surface or the second surface.

8. A damper for a glove box, comprising;
a cylinder;
a piston movably disposed in the cylinder; and
a valve movably disposed in an accommodation portion of the piston,
wherein the piston comprises a piston body in which an orifice is formed, a rod formed to protrude from the piston body and in which the accommodation portion is disposed, and a plurality of stoppers disposed on the rod,
the valve comprises a valve body, a pin formed to protrude from the valve body to have an end portion thereof disposed in the orifice, and a leg and a hook formed to protrude from the valve body, and
the hook is disposed to correspond to each of the stoppers.

9. The damper of claim 8 , wherein:
the stoppers comprise a first stopper disposed on a first surface of the rod and a second stopper disposed on a second surface of the rod;
a first separation distance from the piston body to the first stopper is greater than a second separation distance from the piston body to the second stopper; and
a hook portion of the hook is disposed between the piston body and the first stopper or between the piston body and the second stopper.

10. The damper of claim 8 , further comprising a sealing member disposed on an outer side surface of the piston body.

11. The damper of claim 8 , wherein:
the rod comprises a first surface and a second surface opposite to the first surface; and
a recognition part is disposed on the first surface or the second surface.

12. A glove box comprising:
a glove box body and a cover forming an accommodation space therebetween; and
the damper of claim 8 ,
wherein the glove box body is rotationally disposed in a dashboard of a vehicle, and
the damper adjusts a movement speed of the glove box body.

13. The damper of claim 9 , wherein an outer side surface of the pin comprises an inclined surface having a predetermined inclination.

14. The damper of claim 9 , wherein a contour of the pin has a cross-sectional area that decreases towards an end portion thereof.

15. The damper of claim 13 , wherein a first length of the pin is greater than a second length of the leg based on the valve body.

16. The damper of claim 9 , wherein the leg comprises:
a first region formed to protrude from the valve body in a first direction;
a second region extending from an end portion of the first region in a second direction; and
a third region extending from an end portion of the second region in the first direction.

17. The damper of claim 16 , wherein a distance from the valve body to the end portion of the first region in the first direction is smaller than another distance from the valve body to an end portion of the third region in the first direction.

18. The damper of claim 16 , wherein the end portion of the first region and an end portion of the third region are configured to come into contact with the piston body due to movement of the valve.

19. The damper of claim 9 , wherein the leg is provided as at least two legs disposed to be rotationally symmetrical with respect to a center of the valve body.

20. The damper of claim 8 , wherein the piston further comprises a protruding portion formed to protrude from the piston body to allow the orifice to extend.

21. A damper for a glove box, comprising:
a cylinder;
a piston movably disposed in the cylinder;
a valve movably disposed in an accommodation portion of the piston; and
an elastic member elastically supporting the valve,
wherein the piston comprises a piston body in which an orifice is formed, a rod formed to protrude from the piston body and in which the accommodation portion is formed, and a plurality of stoppers disposed on the rod,
the valve comprises a valve body, a pin formed to protrude from the valve body to have an end portion thereof disposed in the orifice, and a hook formed to protrude from the valve body,
the elastic member is disposed between the piston body and the valve body, and
the hook is disposed to correspond to each of the stoppers.

22. The damper of claim 21 , wherein:
the stoppers comprise a first stopper disposed on a first surface of the rod and a second stopper disposed on a second surface of the rod;
a first separation distance from the piston body to the first stopper is greater than a second separation distance from the piston body to the second stopper; and
a protruding portion of the hook is disposed between the piston body and the first stopper or between the piston body and the second stopper.

23. The damper of claim 22 , wherein an outer side surface of the pin comprises an inclined surface having a predetermined inclination.
