Abstract

An embodiment is a vehicle door opening and closing apparatus. The vehicle door opening and closing apparatus including a vehicle door, a rail mounted on a vehicle body, a roller unit mounted on the vehicle door, the roller unit configured to move along the rail and allow the vehicle door to open and close in a mode selected from a swing mode and a sliding mode, and a hold lock mounted on the vehicle body, the hold lock including a passing rod configured to releasably hold the roller unit in a predetermined position.

First claim

What is claimed is:

1. A vehicle door opening and closing apparatus, comprising:
a vehicle door;
a rail mounted on a vehicle body;
a roller unit mounted on the vehicle door, the roller unit configured to move along the rail and allow the vehicle door to open and close in a mode selected from a swing mode and a sliding mode; and
a hold lock mounted on the vehicle body, the hold lock including a passing rod configured to releasably hold the roller unit in a predetermined position.

2. The vehicle door opening and closing apparatus according to claim 1 , wherein the roller unit includes a body having a through hole, and the passing rod is configured to releasably engage with the through hole of the body.

3. The vehicle door opening and closing apparatus according to claim 2 , wherein a longitudinal axis of the passing rod is perpendicular to a plane of the body, and the passing rod is configured to move in a direction perpendicular to the plane of the body.

4. The vehicle door opening and closing apparatus according to claim 2 , wherein the passing rod is configured to be moved by an actuator in a direction perpendicular to a plane of the body, the actuator having a drive gear, and the passing rod having a plurality of teeth meshing with the drive gear.

5. The vehicle door opening and closing apparatus according to claim 4 , wherein the plurality of teeth are spaced apart from each other in a longitudinal direction of the passing rod.

6. The vehicle door opening and closing apparatus according to claim 1 , wherein the passing rod has a stopper on a middle portion thereof, and an outer diameter of the stopper is greater than an outer diameter of the passing rod.

7. The vehicle door opening and closing apparatus according to claim 2 , further comprising a grip member mounted in the through hole of the body, wherein the grip member is configured to grip the passing rod when the passing rod passes through the through hole of the body.

8. The vehicle door opening and closing apparatus according to claim 7 , wherein the grip member has a hole defined therein, and the passing rod is configured to be inserted into the hole of the grip member.

9. The vehicle door opening and closing apparatus according to claim 7 , wherein the grip member includes a cylindrical portion, a head portion, and a hook, the cylindrical portion being inserted into the through hole of the body, the head portion on an upper end of the cylindrical portion, and the hook on a lower end of the cylindrical portion.

10. The vehicle door opening and closing apparatus according to claim 9 , wherein the head portion is attached to an upper surface of the body adjacent to the through hole, and the hook is attached to a lower surface of the body adjacent to the through hole.

11. The vehicle door opening and closing apparatus according to claim 9 , wherein the grip member has a plurality of slits provided in the cylindrical portion and the hook, the plurality of slits being spaced apart from each other in a circumferential direction of the cylindrical portion, and each slit extends in a longitudinal direction of the cylindrical portion.

12. The vehicle door opening and closing apparatus according to claim 11 , wherein the grip member further includes a plurality of pads on an outer circumferential surface of the cylindrical portion.

13. The vehicle door opening and closing apparatus according to claim 12 , wherein the plurality of pads are between the plurality of slits.

14. The vehicle door opening and closing apparatus according to claim 9 , wherein the grip member has a chamfer on an inner peripheral edge of the head portion.

15. A vehicle door apparatus, comprising:
a vehicle door;
a rail mounted on a vehicle body;
a roller unit mounted on the vehicle door, the roller unit including a body having a through hole, the roller unit configured to move along the rail and allow the vehicle door to open and close in a mode selected from a swing mode and a sliding mode;
an actuator having a drive gear;
a hold lock mounted on the vehicle body, the hold lock including a passing rod configured to releasably engage with the through hole of the body of the roller unit, the passing rod being configured to be moved by the actuator in a direction perpendicular to a plane of the body, the passing rod having a plurality of teeth configured to be engaged with the drive gear.

16. The vehicle door apparatus according to claim 15 , wherein the passing rod has a stopper on a middle portion thereof, and an outer diameter of the stopper is greater than an outer diameter of the passing rod.

17. The vehicle door apparatus according to claim 15 , further comprising a grip member mounted in the through hole of the body, wherein the grip member is configured to grip the passing rod when the passing rod passes through the through hole of the body.

18. The vehicle door apparatus according to claim 17 , wherein the grip member has a hole defined therein, and the passing rod is configured to be inserted into the hole of the grip member.

19. A vehicle door apparatus, comprising:
a vehicle door;
an upper rail, a center rail, and a lower rail mounted on a vehicle body;
an upper roller unit, a center roller unit, and a lower roller unit on the vehicle door, the upper and lower roller units having a body having a through hole, the upper, center, and lower roller units being configured to move along the respective rail and allow the vehicle door to open and close in a mode selected from a swing mode and a sliding mode;
an upper hold lock and a lower hold lock on the vehicle body, each of the upper and lower hold locks including a passing rod configured to releasably engage with the through hole of the body of the respective roller unit.

20. The vehicle door apparatus according to claim 19 , wherein each of the passing rods has a stopper on a middle portion thereof, and an outer diameter of the stopper is greater than an outer diameter of the passing rod.
