Problems solved by technology

Therefore, the forming height of the inner panel 2 in this region is high, and the line length varies greatly, so breakage is likely to occur during forming.
[0039] To avoid this, as in Figure 10 As shown in (b), it is necessary to flatten the angle of the vertical wall portion 2' of the inner panel 2, wherein the vertical wall portion 2' is connected to the joint portion of the outer panel from the rear side of the joint portion of the lock reinforcement member 3. However, in this case, the position of the joint surface of the outer panel 1 and the inner panel 2 is shifted to the rear side, so the dent resistance of the inner panel 2 is reduced, and the head of the pedestrian hits the center of the hood. Pedestrian protection performance degradation in the position on the rear side

Abstract

Provided is an engine cover used for a vehicle, wherein an internal panel (2) has a recess (2h), a front end part thereof is fixed on an external panel (1) through curring, a rear part thereof is jointed to the external panel (1) through Mastic. A bottom of the recess (2h) is provided with a hole (2a), a downward protruding part of a locking stiffening member (3) is embedded in the hole (2a), a flange (3e) of the locking stiffening member (3) is jointed and fixed at a hole peripheral part (2d) of the internal panel (2).

Description

technical field [0001] The present invention relates to a vehicle hood excellent in pedestrian protection performance, and more particularly to a vehicle hood capable of improving the dent resistance of a portion directly above a striker at low cost. Background technique [0002] In a vehicle such as an automobile having a hood at the front of the vehicle body, the hood includes an outer panel, an inner panel disposed on the lower surface side of the outer panel, and a reinforcement member disposed between the outer panel and the inner panel. Furthermore, in order to secure the rigidity and strength of the engine hood itself, the outer panel and the inner panel are joined so as to form a closed cross-sectional structure with a space therebetween, and a plurality of reinforcing members are provided inside. [0003] In recent years, in addition to hood rigidity, dent resistance, flare rigidity, etc., the hood panel has been required to have performance (pedestrian protection p...
