Abstract

A structure includes a rail mounted on a vehicle body, a rail roller device connected to the rail, a slider mounted on the rail roller device, a movement support device having a first side fixed to a door and a second side connected to the slider, and a catch-pawl locking device including catches and pawls locked to or unlocked from one another while rotating. The catches and the pawls include a first catch and a first pawl for restricting a movement of the rail roller device in a first direction when the first catch and the first pawl are locked to each other, and a second catch and a second pawl for restricting a movement of the movement support device in a second direction perpendicular to the first direction when the second catch and the second pawl are locked.

First claim

What is claimed is:

1. A structure for preventing a sliding door from swaying, the structure comprising:
a rail configured to be mounted on a vehicle body in a longitudinal direction of the vehicle body;
a rail roller device rollably connected to the rail;
a slider mounted on the rail roller device;
a movement support device having a first side configured to be fixed to a door and a second side rollably connected to the slider, the movement support device being configured to support the door; and
a catch-pawl locking device comprising catches and pawls configured to be locked to or unlocked from one another while rotating, the catches and the pawls comprising a first catch and a first pawl configured to restrict a movement of the rail roller device in a first direction when the first catch and the first pawl are locked to each other, and a second catch and a second pawl configured to restrict a movement of the movement support device in a second direction perpendicular to the first direction when the second catch and the second pawl are locked to each other,
wherein the first catch, the first pawl, the second catch, and the second pawl are configured to operate in conjunction with one another, such that the door moves in one of the first and second directions and then move in the other of the first and second directions while the door is opened or closed.

2. The structure of claim 1 , wherein the rail is configured to be mounted at a lower side of the vehicle body.

3. The structure of claim 1 , further comprising a first striker on the rail, wherein the first catch is configured to be rotated by being caught by the first striker.

4. The structure of claim 1 , further comprising an internal space in the slider, wherein the movement support device is inserted into the internal space.

5. The structure of claim 1 , further comprising a second striker on the movement support device, wherein the second catch is configured to be rotated by being caught by the second striker.

6. The structure of claim 5 , wherein the slider includes a movement hole, and wherein the movement hole is a movement path for the second striker.

7. The structure of claim 1 , wherein the movement support device comprises:
a support member mounted on the door; and
a roller rotatably connected to the support member.

8. The structure of claim 1 , wherein the catch-pawl locking device comprises:
a first lever configured to connect the first catch and the second pawl; and
a second lever configured to connect the second catch and the first pawl.

9. The structure of claim 1 , wherein:
the second pawl and the second catch are unlocked from each other when the first pawl and the first catch are locked to each other; and
the second pawl and the second catch are locked to each other when the first pawl and the first catch are unlocked from each other.

10. The structure of claim 1 , wherein the first catch has a catching groove and the first pawl has a catching portion configured to be caught by the catching groove.

11. The structure of claim 1 , wherein the door is configured to move in the second direction and then move in the first direction while the door is opened.

12. The structure of claim 1 , wherein the door is configured to move in the first direction and then move in the second direction while the door is closed.

13. A structure for preventing a sliding door from swaying, the structure comprising:
a rail configured to be mounted on a vehicle body in a longitudinal direction of the vehicle body;
a rail roller device rollably connected to the rail;
a slider mounted on the rail roller device;
a movement support device having a first side configured to be fixed to a door and a second side rollably connected to the slider, the movement support device being configured to support the door;
a catch-pawl locking device comprising catches and pawls configured to be locked to or unlocked from one another while rotating, the catches and the pawls comprising a first catch and a first pawl configured to restrict a movement of the rail roller device in a first direction when the first catch and the first pawl are locked to each other, and a second catch and a second pawl configured to restrict a movement of the movement support device in a second direction perpendicular to the first direction when the second catch and the second pawl are locked to each other; and
a first spring on a rotation shaft of the first catch to apply elastic force;
wherein the first catch includes an insertion groove having a shape recessed inward; and
wherein the first catch, the first pawl, the second catch, and the second pawl are configured to operate in conjunction with one another, such that the door is configured to move in one of the first and second directions and then move in the other of the first and second directions while the door is opened or closed.

14. The structure of claim 13 , further comprising a second spring on a rotation shaft of the first pawl to apply elastic force in a direction opposite to the direction in which the elastic force of the first spring is applied.

15. A vehicle comprising:
a vehicle body;
a sliding door coupled to the vehicle body;
a rail mounted on a lower side of the vehicle body in a longitudinal direction of the vehicle body;
a rail roller device rollably connected to the rail;
a slider mounted on the rail roller device;
a movement support device having a first side fixed to the sliding door and a second side rollably connected to the slider, the movement support device being configured to support the sliding door; and
a catch-pawl locking device comprising catches and pawls configured to be locked to or unlocked from one another while rotating, the catches and the pawls comprising a first catch and a first pawl configured to restrict a movement of the rail roller device in a first direction when the first catch and the first pawl are locked to each other, and a second catch and a second pawl configured to restrict a movement of the movement support device in a second direction perpendicular to the first direction when the second catch and the second pawl are locked to each other,
wherein the first catch, the first pawl, the second catch, and the second pawl are configured to operate in conjunction with one another, such that the sliding door is configured to move in one of the first and second directions and then move in the other of the first and second directions while the sliding door is opened or closed.

16. The vehicle of claim 15 , further comprising a first striker on the rail, wherein the first catch is configured to be rotated by being caught by the first striker.

17. The vehicle of claim 15 , further comprising an internal space in the slider, wherein the movement support device is inserted into the internal space.

18. The vehicle of claim 15 , further comprising a second striker on the movement support device, wherein the second catch is configured to be rotated by being caught by the second striker.

19. The vehicle of claim 18 , wherein the slider includes a movement hole, and wherein the movement hole is a movement path for the second striker.

20. The vehicle of claim 15 , wherein the movement support device comprises:
a support member mounted on the door; and
a roller rotatably connected to the support member.
