Patent ID: 7789454

Claim:
A frame structure for vertically mounting an integrated package on a rear floor panel of a vehicle, the frame structure comprising: a rear floor frame disposed behind a rear seat of the vehicle in a transverse direction of body of the vehicle; and a pair of guide frames are installed in parallel with each other behind the rear floor frame in a longitudinal direction of the vehicle body, the guide frames being mechanically connected to the rear floor frame in a perpendicular orientation; and a lower frame attached on an under side of the integrated package, wherein the lower frame is slidably engaged with the guide frames to be able to move along the guide frames, wherein each of the guide frames has a U-shaped cross-section and the front end thereof is securely fixed to the rear floor frame by means of spot welding, the lower frame includes a pair of guide groove sections each of which has a cross-sectional shape corresponding to the U-shape of the guide frames so that the guide groove sections can slidably move along the guide frames, the rear floor frame is provided with fixing protrusions protruding upwardly at or near the positions where the front ends of the guide frames are fixed to the rear floor frame, thereby allowing the integrated package to be accurately seated at a predetermined position of the lower frame, and each of the guide groove sections of the lower frame is provided with a protrusion-accommodating slit formed at the front end thereof so that when the front ends of the guide groove sections of the lower frame move slidably along the guide frames, the fixing protrusions can be inserted into the protrusion-accommodating slits to stop the movement of the front ends of the guide groove sections at the predetermined position of the lower frame.
