Vehicle hood
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.
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 part 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 a 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 a forefront among the beads and a portion located on a rearmost bead located most rearward among the beads in a vehicle front-hack direction; and
an index value 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 an adhesive component at a position opposed to the outer panel between the foremost bead and a front 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
a thickness of the inner panel is at least 0.8 times a 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.
