Abstract

A vehicle door unit comprises a rotating lever supported rotatably about a first shaft at a first end, a door mounting coupled rotatably about a second shaft to a second end of the rotating lever, a door attached to the door mounting and being configured to cover an opening in a vehicle and to close off a vehicle interior, and a drive unit configured to rotate the rotating lever about the first shaft between a closed position and an open position. The rotating lever is configured to move the second shaft, on a movement from the closed position to the open position, on a circular path, due to which the door mounting is first moved into the vehicle interior and, on further rotation of the rotating lever, out of the vehicle interior.

Claims

1. A vehicle door unit comprising:

a rotating lever supported rotatably at a first end about a first shaft;

a door mounting coupled rotatably about a second shaft to a second end of the rotating lever;

a door fixedly and directly attached to the door mounting and being configured to cover an opening in a vehicle and to close off a vehicle interior; and

a drive unit configured to rotate the rotating lever between a closed position and an open position about the first shaft,

wherein the rotating lever is configured to move the second shaft on a circular path during a movement from the closed position to the open position,

wherein a complete circle containing the circular path of the movement of the second shaft is divided into two halves by a dividing line, the dividing line extends perpendicular to an outer skin of the vehicle and adjacent the first shaft and extends from the outer skin of the vehicle through the first shaft, and

wherein the rotating lever is configured to move the second shaft from a first half of the circle over the dividing line into the second half of the circle during the movement from the closed position to the open position upon rotation of the rotating lever in a first direction, due to which rotation of the rotating lever in the first direction the second shaft and the door mounting are moved initially into the vehicle interior and, on further rotation of the rotating lever in the first direction, are moved out of the vehicle interior.

2. The vehicle door unit according to claim 1, wherein the rotating lever is configured to move the door attached to the door mounting into the vehicle interior during the movement of the second shaft on the first half of the circle and to move the door away from an edge of the vehicle opening during the movement of the second shaft on the first and second half of the circle.

3. The vehicle door unit according to claim 1, wherein the rotating lever is further configured to move the second shaft, after passing through the second half of the circle, over the dividing line into the first half of the circle.

4. The vehicle door unit according to claim 1, further comprising:

a guide element, having an open end and a closed end; and

an engaging element in engagement with the guide element at least in the closed position of the rotating lever,

wherein the guide element is coupled to a frame element surrounding the opening in the vehicle and the engaging element is coupled to the door, and one of;

wherein the open end of the guide element lies in a direction of the rotating lever, or

wherein the engaging element is coupled to a frame element surrounding the opening in the vehicle and the guide element is coupled to the door, and wherein the closed end of the guide element lies in the direction of the rotating lever.

5. The vehicle door unit according to claim 4, wherein the guide element and the engaging element are configured in such a way that on rotation of the rotating lever by the drive unit, the engaging element is moved relative to the guide element initially towards the closed end and on further rotation is moved back to the open end of the guide element.

6. The vehicle door unit according to claim 4, wherein the guide element has a curved shape and is configured to guide the door into the vehicle interior on rotation of the rotating lever by the drive unit.

7. The vehicle door unit according to claim 4, wherein the guide element is configured and arranged in such a way that the engaging element leaves the guide element through the open end during the rotation of the rotating lever.

8. The vehicle door unit according to claim 1, further comprising:

a pair of retaining elements, of which a first retaining element is attached to a frame element surrounding the opening in the vehicle and a second retaining element is attached to the door,

wherein in the closed position of the rotating lever, the first and second retaining elements contact one another in an interacting manner and prevent a movement of the door outwards from the vehicle interior.

9. The vehicle door unit according to claim 8, wherein the rotating lever is configured in such a way that on rotation of the rotating lever from the closed position, a part of the door, together with the retaining element attached to the part of the door, is moved initially into the vehicle interior and the first and second retaining elements are separated from one another, and wherein the retaining element attached to the part of the door is moved by further rotation of the rotating lever in a curve around the retaining element attached to the frame element.

10. The vehicle door unit according to claim 8, wherein the first retaining element is T-shaped or L-shaped and the second retaining element is T-shaped or L-shaped, wherein a limb of each of the first and second retaining elements stands freely, and wherein the free-standing limbs of both retaining elements lie parallel to one another in the closed position of the rotating lever and contact one another in an interacting manner.

11. The vehicle door unit according to claim 1, further comprising:

an actuator coupled rotatably to the rotating lever and the door respectively,

wherein the actuator is configured to rotate the door about the second shaft relative to the rotating lever and move the door away from the opening in the vehicle.

12. The vehicle door unit according to claim 1, wherein the rotating lever comprises two limbs arranged obliquely to one another.

13. The vehicle door unit according to claim 12, wherein the rotating lever is configured in such a way that, in the open position, the two limbs encompass at least one of a part of a vehicle outer skin and a part of a frame element surrounding the opening in the vehicle.

14. The vehicle door unit according to claim 1, wherein the rotating lever is configured to move the second shaft from the first half of the circle into the second half of the complete circle over the dividing line, wherein the dividing line intersects the circle on a side of the circle facing the vehicle interior.

15. A vehicle comprising a vehicle door unit comprising:

a rotating lever supported rotatably at a first end about a first shaft;

a door mounting coupled rotatably about a second shaft to a second end of the rotating lever;

a door fixedly and directly attached to the door mounting and being configured to cover an opening in a vehicle and to close off a vehicle interior; and

a drive unit configured to rotate the rotating lever between a closed position and an open position about the first shaft,

wherein the rotating lever is configured to move the second shaft on a circular path during a movement from the closed position to the open position,

wherein a complete circle containing the circular path of the movement of the second shaft is divided into two halves by a dividing line, the dividing line extends perpendicular to an outer skin of the vehicle and adjacent the first shaft and extends from the outer skin of the vehicle through the first shaft, and

wherein the rotating lever is configured to move the second shaft from a first half of the circle over the dividing line into the second half of the circle during the movement from the closed position to the open position upon rotation of the rotating lever in a first direction, due to which rotation of the rotating lever in the first direction the second shaft and the door mounting are moved initially into the vehicle interior and, on further rotation of the rotating lever in the first direction, are moved out of the vehicle interior.

16. The vehicle according to claim 15, wherein the rotating lever is configured to move the second shaft from the first half of the circle into the second half of the circle over the dividing line, wherein the dividing line intersects the circle on a side of the circle facing the vehicle interior.
