Abstract

A rear vehicle body reinforcing structure may include a rear reinforcing member deployed on a periphery of a vehicle body rear door opening and configured to be coupled to a rear vehicle body, in which the rear reinforcing member is opened upward in a height direction of a vehicle.

First claim

What is claimed is:

1. A rear vehicle body reinforcing structure comprising:
a rear reinforcing member deployed on a periphery of a vehicle body rear door opening and configured to be coupled to a rear vehicle body,
wherein the rear reinforcing member is opened upward in a height direction of a vehicle, and
wherein the rear vehicle body includes:
rear side members at both left and right sides, which extend in a longitudinal direction of the vehicle and are deployed at both left and right sides in a width direction of the vehicle;
rear shock absorber mounting reinforcing members at both left and right sides, which are coupled to tops of the rear side members at both left and right sides in the height direction of the vehicle;
a rear cross lower reinforcing member connecting the rear side members at both left and right sides in the width direction of the vehicle;
quarter center reinforcing members at both left and right sides, of which a first end is coupled to the rear shock absorber mounting reinforcing members at both left and right sides and a second end is coupled to center pillars extended in the height direction of the vehicle and deployed at both left and right sides in the width direction of the vehicle;
quarter upper pillar members at both left and right sides, of which a first end is coupled to the rear shock absorber mounting reinforcing members at both left and right sides and a second end is coupled to roof side rail members extended in the longitudinal direction of the vehicle and deployed at both left and right sides in the width direction of the vehicle; and
a rear cross upper reinforcing member connecting the quarter upper pillar members at both left and right sides.

2. The rear vehicle body reinforcing structure of claim 1 , wherein the rear reinforcing member has a “U” shape which is opened upward in the height direction of the vehicle.

3. The rear vehicle body reinforcing structure of claim 1 , wherein:
the vehicle body rear door opening is formed by the rear cross upper reinforcing member, the quarter upper pillar members at both left and right sides, and the rear side members at both left and right sides.

4. The rear vehicle body reinforcing structure of claim 1 , wherein:
the rear reinforcing member has an annular structure in which both ends in a longitudinal direction of the rear reinforcing member are coupled to the rear cross upper reinforcing member.

5. The rear vehicle body reinforcing structure of claim 4 , wherein:
two first extension members protrude at a predetermined portion of the rear reinforcing member in the longitudinal direction and the two first extension members are coupled to the rear shock absorber mounting reinforcing members at both left and right sides.

6. The rear vehicle body reinforcing structure of claim 5 , wherein:
two second extension members integrally protrude and extend at both left and right portions in a width direction of the rear reinforcing member and the two second extension members are coupled to tops of rear fore-ends of the rear side members at both left and right sides in the longitudinal direction of the vehicle, respectively.

7. The rear vehicle body reinforcing structure of claim 6 , wherein:
the two second extension members are deployed below two first extension members in the height direction of the vehicle.

8. The rear vehicle body reinforcing structure of claim 6 , wherein:
a third extension member protrudes and extends at a central portion of the rear reinforcing member in the width direction and the third extension member is connected with the rear cross lower reinforcing member.

9. The rear vehicle body reinforcing structure of claim 8 , wherein:
each of the first extension members, the second extension members, and the third extension members protrudes to a front in the longitudinal direction of the vehicle.

10. The rear vehicle body reinforcing structure of claim 9 , wherein:
a fourth extension member extends to protrude to a rear in the longitudinal direction of the vehicle at a central portion of the rear reinforcing member in the width direction of the vehicle, and a tail gate latch is configured to be disposed in the fourth extension member.

11. The rear vehicle body reinforcing structure of claim 10 , wherein:
the fourth extension member is deployed on a same line as the third extension member in the longitudinal direction of the vehicle.

12. The rear vehicle body reinforcing structure of claim 1 , wherein:
the rear reinforcing member is manufactured by a circular pipe.
