Abstract

Provided is a vehicle hood that allows a reduction in thickness of an outer panel while providing stiffness of the outer panel. A vehicle hood includes an outer panel, an inner panel, and a plurality of adhesive components. The inner panel has a plurality of beads. Each bead has a support part that supports each adhesive component. The adhesive components are provided on the support parts so as to be intermittently aligned along a specific direction. A support-part interval between the support parts adjacent to each other in an intersecting direction is smaller than an adhesive-component interval between the adhesive components adjacent to each other on the support parts.

First claim

1 . A vehicle hood comprising:
an outer panel; an inner panel disposed below the outer panel; and a plurality of adhesive components connecting the outer panel to the inner panel, wherein: the inner panel has a plurality of beads, the beads each having a shape extending along a specific direction and being disposed so as to be intermittently aligned along an intersecting direction intersecting with the specific direction; each of the beads has a support pan that has a shape extending along the specific direction and supports each of the adhesive components at a position opposed to the outer panel; the adhesive components are provided on the support parts so as to be intermittently aligned along the specific direction; and a support-part interval between the support parts adjacent to each other in the intersecting direction is smaller than an adhesive-component interval between the adhesive components adjacent to each other on each of the support parts.

2 . The vehicle hood according to claim 1 ,
wherein adhesive components disposed on the specific support part among the support parts and adhesive components disposed on a support part adjacent to the specific support part in the intersecting direction are disposed in a zigzag pattern.

3 . The vehicle hood according to claim 1 ,
wherein: the outer panel is made of aluminum or aluminum alloy; the outer panel has a middle adhesive region between a portion located on a foremost bead located in the forefront among the beads and a portion located on a rearmost bead located most rearward among the beads in a vehicle front-back direction; and an index value is 175 to 235, the index value being represented by a ratio of the adhesive-component interval to a thickness of the outer panel in the middle adhesive region.

4 . The vehicle hood according to claim 3 ,
wherein: the inner panel further has a front support part that supports the adhesive component at a position opposed to the outer panel between the foremost bead and a from end of the inner panel; the outer panel has a front adhesive region between the portion located on the foremost bead and a front end of the outer panel in the vehicle front-back direction; and an index value is 80 to 100, the index value being represented by a ratio of a front adhesive-component interval between the adhesive components in a vehicle width direction in the front adhesive region to the thickness of the outer panel.

5 . The vehicle hood according to claim 1 ,
wherein: an edge of the outer panel configures a folded grip part that grips an edge of the inner panel from two sides in a thickness direction of the inner panel while being folded inward; and thickness of the inner panel is at least 0.8 times the thickness of the outer panel.

6 . The vehicle hood according to claim 5 ,
wherein the thickness of the inner panel is not more than 1.1 times the thickness of the outer panel.
