Further, on the top of left A column reinforcement plate and right A column reinforcement plate, L bracket is all installed, in the time that installation turns to support, realizes the function of attachment point by this L bracket, can improve and turn to the reliability and the mode targets that support attachment point.
Further, inward flange at Front Windshield crossbeam offers the guide groove of " mouth " font, in the time that instrument platen assembly is installed, can play good directional tagging to the assembling of instrument platen assembly front end at directions X, carry out spacing in Z direction to instrument platen assembly, XY direction is adjustable, has ensured the assembly clearance of instrument platen assembly.
Further, at top and the middle part of front panel, a few font supports are all installed, can change into and being arranged in front panel being arranged on the HVAC turning in support by these a few font supports, promote the mode that turns to support.
In the present invention, front panel and front wall frame have formed the near closed hollow ring of in X, Y, tri-directions of Z " three horizontal four is vertical ", NVH aspect of performance at transmission, body in white bulk strength and rigidity and the car load of collision safety power is improved, surface-type feature (reinforced rib arranging) by front panel self replaces traditional reinforcement, with respect to existing automobile front wall, in the situation that reinforcement is less, also reach vehicle performance target, reduce car load manufacturing cost, also improved the manufacturing process of front wall simultaneously.
