Top surface and slope can preferably share power suffered by cross-beam connecting plate, three sides of reinforcer are bonded weldering with cross-beam connecting plate
Connect, stressing conditions is had a supporting role, the power on each side of cross-beam connecting plate effectively can be delivered to reinforcer.
Further, the slope of the reinforcer is provided with the first reinforcement.The reinforcement strengthens reinforcer entirety
Structural strength.
Further, the middle part of the support member is provided with a vertical groove being recessed backward, the groove and the installation bolt
Welded with merging；Support member lower end, left side and the right side are respectively equipped with the bottom, left side and right side of cross-beam connecting plate one by one
Corresponding the 3rd flange to connect.The groove of support member make it that the stress of attachment structure is more stable.
Further, it is provided with the second reinforcement at the second welding flange on the support member.The reinforcement strengthens support
The overall structural strength of part.
Further, the bottom of the cross-beam connecting plate is provided with a through hole, and the installation bolt passes through from the through hole.
The beneficial effects of the utility model are：
1st, because reinforcer is designed as trapezoidal top surface and slope so that one triangle of installation bolt periphery formation
Space structure, the rigidity of automotive floor panel crossbeam mount point is improved, effectively improve the NVH performances of vehicle, improved seating and relax
Adaptive.
2nd, due to being longitudinally provided with support member between reinforcer and cross-beam connecting plate, the installation strength of installation bolt is improved,
So that attachment structure stability under loading.
