a first-stage door configured to be rotated open with respect to a first hinge;
a second-stage door configured to be rotated open together with the first-stage door with respect to a second hinge;
a cross member;
a motor module positioned on the cross member and configured to apply a driving force to the first hinge and the second hinge individually; and
a sliding unit configured such that the cross member is configured to be moved together with the motor module along the sliding unit, wherein the cross member is configured to be moved along the sliding unit so that the motor module is selectively fastened to the first hinge or the second hinge.
2. The two-stage open structure of claim 1 , wherein the sliding unit further comprises:
a rail portion positioned on a vehicle body, wherein at least a portion of the cross member is inserted into and configured to be moved along the rail portion; and
a guide portion positioned on the rail portion and configured to allow the cross member to be rotated.
3. The two-stage open structure of claim 2 , further comprising a protrusion portion positioned on the cross member and in contact with the guide portion so that the cross member is configured to rotationally move along the rail portion.
4. The two-stage open structure of claim 1 , further comprising a fixation member positioned at an end of the cross member, the end being adjacent to a vehicle body, and the fixation member extending along a longitudinal direction of the cross member and inserted into an inside of the vehicle body.
5. The two-stage open structure of claim 4 , wherein the fixation member is configured to be inserted into a first insertion groove formed on the vehicle body at a position corresponding to a position where the motor module is fastened to the first hinge.
6. The two-stage open structure of claim 4 , wherein the fixation member is configured to be inserted into a second insertion groove formed on the vehicle body at a position corresponding to a position where the motor module is fastened to the second hinge.
7. The two-stage open structure of claim 1 , wherein the motor module further comprises:
a fastening portion to which the first hinge or the second hinge is selectively fastened;
a housing fixedly positioned on the cross member integrally with the fastening portion; and
a drive unit positioned inside the housing and configured to apply the driving force to the fastening portion.
8. The two-stage open structure of claim 7 , wherein the cross member is configured such that when the housing is moved along the sliding unit, the cross member is rotated to bring the fastening portion into contact with the first hinge or the second hinge.
9. The two-stage open structure of claim 1 , further comprising a bracket positioned between the second hinge and a vehicle body.
10. A two-stage open structure of a vehicle door, the two-stage open structure comprising:
a first-stage door configured to be rotated open with respect to a first hinge;
a second-stage door configured to be rotated open together with the first-stage door with respect to a second hinge;
a cross member;
a motor module positioned on the cross member and configured to apply a driving force to the first hinge and the second hinge individually;
a first bracket positioned between the first hinge and the second-stage door; and
a fixation pin configured to fix the first hinge by penetrating through the first hinge and the first bracket.
11. The two-stage open structure of claim 10 , wherein at least two through holes are formed in the first hinge to cooperate with the fixation pin when the first-stage door is in an opened state or a closed state.
12. The two-stage open structure of claim 10 , further comprising a second bracket positioned between the second hinge and a vehicle body.
13. A vehicle comprising:
a vehicle body;
a first-stage door coupled to the vehicle body and configured to be rotated open at a first hinge;
a second-stage door coupled to the vehicle body and configured to be rotated open together with the first-stage door at a second hinge;
a cross member;
a motor module positioned on the cross member and configured to apply a driving force to the first hinge and the second hinge individually; and
a sliding unit configured such that the cross member is configured to be moved together with the motor module along the sliding unit, wherein the cross member is configured to be moved along the sliding unit so that the motor module is selectively fastened to the first hinge or the second hinge.
14. The vehicle of claim 13 , wherein the sliding unit further comprises:
a rail portion positioned on the vehicle body, wherein at least a portion of the cross member is inserted into and configured to be moved along the rail portion; and
a guide portion positioned on the rail portion and configured to allow the cross member to be rotated.
15. The vehicle of claim 14 , further comprising a protrusion portion positioned on the cross member and in contact with the guide portion so that the cross member is configured to rotationally move along the rail portion.
16. The vehicle of claim 13 , further comprising a fixation member positioned at an end of the cross member, the end being adjacent to the vehicle body, and the fixation member extending along a longitudinal direction of the cross member and inserted into an inside of the vehicle body.
17. The vehicle of claim 13 , wherein the motor module further comprises:
a fastening portion to which the first hinge or the second hinge is selectively fastened;
a housing fixedly positioned on the cross member integrally with the fastening portion; and
a drive unit positioned inside the housing and configured to apply the driving force to the fastening portion.
18. The vehicle of claim 17 , wherein the cross member is configured such that when the housing is moved along the sliding unit, the cross member is rotated to bring the fastening portion into contact with the first hinge or the second hinge.
19. The vehicle of claim 16 , wherein the fixation member is configured to be inserted into a first insertion groove formed on the vehicle body at a position corresponding to a position where the motor module is fastened to the first hinge.
20. The vehicle of claim 16 , wherein the fixation member is configured to be inserted into a second insertion groove formed on the vehicle body at a position corresponding to a position where the motor module is fastened to the second hinge.
