DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. The drawings show a hood structure of a vehicle as an example of a hood structure of the vehicle. In FIGS. 1 and 2, a hood 3 is formed by joining a hood outer panel 1 and a hood inner panel 2. The outer panel 1 and the inner panel 2 are made of aluminum or aluminum alloy.

The bonnet inner panel 2 has a plurality of annular beads 4 as shown in FIG. 2 (a view of the panel 2 in FIG. 2 viewed from the engine room side). Is set to The above-mentioned annular bead 4 protrudes toward the engine room as shown in FIG. 3, and a plurality of low portions 4a (portions having a small amount of protrusion) are integrally formed per one annular bead 4, and this bottom portion 4a is formed. The bonnet inner panel 2 and the bonnet outer panel 1 are joined via the rubber 6 by utilizing. The rubber 6 is bonded and fixed to the upper surface of the hood inner panel 2.

In addition, the above-described hood inner panel 2
As shown in FIG. 2, ridges 7, 7 extending from the substantially center of the front portion toward the left, right, rear and rear are integrally formed, and the ridges 7, 7 extending in the slant direction improve the strength of the bonnet inner panel 2 in the ridge direction. Is being planned. The above-mentioned ridges 7, 7 protrude toward the engine room similarly to the above-mentioned bead 4, and water drain holes 8 are formed in these two ridges 7, 7 in a protruding manner.

A striker 9 is disposed at the center of the front of the bonnet inner panel 2 as shown in FIGS. 1 and 2, and on both left and right sides of the striker 9 as shown in FIGS. And bump rubbers 10 and 10 as a reaction force generating elastic body. Here, the above striker 9
Is fixedly connected to the bonnet panel 2 via an iron plate mounting member (not shown).
Locking groove 12 of fork 11 as locking means as shown in FIG.
Locked by.

The above-described fork 11 is configured to be rotatable around a support shaft 14 of a bonnet lock body 13 (see FIG. 1) provided on the vehicle body side. Is a tilt angle θ1 from the center (the center of the locking point of the striker 9) in one direction as shown in FIG.
(Approximately 30 degrees) and the center (strike 9
From the locking point center) to the other direction in the inclination angle θ2 (about 30
(In degrees) in combination with an inverted V-shaped engaging portion to restrict upward movement of the hood 3 when the hood 3 is closed, as well as in the vehicle width direction of the hood 3. (I.e., left and right directions).

As shown in FIG. 5, the bump rubber 10 as the above-mentioned reaction force generating elastic body has its neck fitted and fixed to a predetermined portion of the bonnet inner panel 2, and
At the time of closing, the bump rubber 10 comes into contact with a shroud upper panel 15 as a vehicle body-side member as shown in FIG.
The bonnet 3 is configured to apply a predetermined reaction force.

By the way, as shown in FIG. 2, the position where the striker 9 and the bump rubbers 10 and 10 are disposed with respect to the hood inner panel 2 described above (the hood An aluminum reinforcement 16 as a reinforcing member is disposed at a position where the closing operation load becomes maximum at the time of closing. The reinforcement 16 is joined to the bonnet inner panel 2 as shown in FIGS. 1 and 5, and forms a closed section 17 by both of them. As shown in FIG. 6, a plurality of beads 18 which are inclined with respect to the vehicle longitudinal direction are integrally formed.

In FIG. 2, a group of beads 18 located on the lower side of the drawing extends in a direction substantially orthogonal to one ridge 7 (lower part 7 of the lower side of the drawing), and a group of beads 18 located on the upper side of the drawing is the other. Is formed so as to extend in a direction substantially perpendicular to the ridge 7 (the upper ridge 7 in the figure).

As shown in FIGS. 6, 7, and 8, each of the beads 18 is formed in a concave groove shape when viewed from above, and is integrally formed so as to protrude toward the engine room. Reference numeral 19 shown by a virtual line in FIG. 2 denotes a stopper rubber for holding a bonnet closed position attached to a wheel apron panel as a vehicle body-side member. In this embodiment, when the bonnet 3 is closed, this stopper rubber is used. 19,1
9 and the bump rubbers 10 and 10 generate a reaction force for pushing the bonnet 3 upward, and the generation of the reaction force and the holding force of the fork 11 for locking the striker 9 cause the bonnet 3 to rattle. Is configured to prevent FIG.
Reference numeral 20 shown in FIG. 7 is a hole for both electrodeposition and weight reduction.

As described above, according to the bonnet structure of the above embodiment, the hood inner panel 2 having the ridges 7 has strength in the ridge direction, but weakness in the direction perpendicular to the ridge 7. Therefore, the bonnet inner panel 2 formed on the above-described reinforcing member (see the reinforcement 16) is used.
Bead 18 extending in a direction substantially perpendicular to the ridge 7 of
Strength reinforcement in the direction in which the bead 18 extends, that is, in the direction substantially perpendicular to the ridge 7 can be achieved. Therefore, even if the bonnet 3 is pressed during the closing operation of the bonnet 3, the deformation of the bonnet outer panel 1 and the bonnet inner panel 2 can be reliably prevented.

The above-mentioned reinforcement 16
In addition, since a plurality of beads 18 are formed, the height of each bead 18 can be reduced, and the size and size of the individual bead 18 can be reduced. As a result, the space efficiency can be improved. Further, since the bead 18 is inclined with respect to the vehicle longitudinal direction, there is an effect that the surface rigidity of the hood 3 in the longitudinal direction and the vehicle width direction can be improved.

In addition, since the bonnet 3 is made of aluminum, the weight of the bonnet 3 can be reduced.
There is an effect that the deformation of the hood 3 can be prevented. In addition, the above-mentioned reaction force generating elastic body (the bump rubber 10
(See Shroud Upper Panel 15) when the hood 3 is closed, so that a sufficient reaction force is generated by the contact structure of the elastic body (see the bump rubber 10). In addition, a pulling force can be always applied to the striker 9, and therefore, there is an effect that the backlash of the bonnet 3 can be reliably prevented.

Further, since the locking groove 12 is formed in the locking means (see the fork 11) for locking the striker 9, the effect that the striker 9 can be securely held by the locking groove 12 is obtained. If an inverted V-shaped engaging portion is provided in the above-described engaging groove 12 as shown in the embodiment, the engaging portion can effectively prevent the bonnet 3 from rattling in the vehicle width direction.
There is an effect that can be regulated.

In correspondence between the configuration of the present invention and the above-described embodiment, the hood of the present invention is
Similarly, the reaction force generating elastic body corresponds to the bump rubber 10, the inner panel corresponds to the bonnet inner panel 2, and the reinforcing member corresponds to the reinforcement 1.
6, the body-side member with which the reaction-force generating elastic body abuts is
Although it corresponds to the shroud upper panel 15 and the locking means corresponds to the fork 11, the present invention is not limited to the configuration of the above-described embodiment.

For example, the hood structure of the vehicle having the above structure is as follows.
It goes without saying that the present invention may be applied to a translid structure other than the bonnet structure. When the ridge portion is formed in the front and rear direction of the vehicle body in the bonnet inner panel 2 described above,
A bead of the reinforcing member 16 may be provided in a direction orthogonal to the ridge.
