The hood 1 is rotatably attached to the vehicle body at the rear of the engine room E via hinges 3 at both rear ends thereof, and has a folding bead 4 near the center in the longitudinal direction. The bending bead 4 is provided to prevent the hood 1 from flying into the vehicle interior and injuring the occupants due to the impact at the time of a frontal collision, and is easily bent upward at the bending bead 4 position. Further, the hood support rod 2 is attached to the upper surface of the strut housing 5 on the side of the engine room E so as to be able to rotate upward, and when the hood is closed, the front fender apron 6
It is fixed to the upper surface of the camera by a clip 7. The tip 2a is processed into an arc shape. Also, when the hood is opened, the hood support rod 2 should be raised upwards, and the tip 2
The hood 1 is held open at a predetermined angle by engaging the hood 1 with the engagement hole 9 provided at the corresponding location of the hood inner 8.

<Problems to be Solved by the Invention> However, in such a conventional technique, when storing the hood support rod 2 on the upper surface of the front fender apron 6, the hood support rod 2 is A clearance lXh is required below and above. That is, the lower clearance 1 is provided to prevent the hood support rod 2 from coming into contact with the vehicle body due to vibrations of the vehicle body and generating noise. Further, the upper clearance h is provided to prevent the hood 1 from hitting the hood support rod 2 due to an overstroke when closing the hood 1. Therefore, the height of the hood 1 relative to the front fender apron 6 increases, and the degree of freedom in shaping the front part of the vehicle body tends to decrease.

The present invention has been made with attention to such conventional techniques, and an object thereof is to provide an automobile hood structure that improves the degree of freedom in shaping the front portion of the vehicle body.

<Means for Solving the Problems> In order to achieve the above object, the automobile hood structure according to the present invention is provided with a recessed portion along the front-rear direction in the hood inner on the lower surface of the hood, and a front end of the hood is provided in the recessed portion. A hood support rod that is supported by a shaft and whose rear end is rotatable downward is housed, and on the vehicle body side, there is a fixed part that engages with the rear end of the hood support rod when the hood is open, and a fixing part that engages with the rear end of the hood support rod when the hood is closed. A stopper portion is provided to prevent at least rearward movement of the rear end of the hood support rod.

The front end of the hood support rod is pivotally supported behind the bent bead.

<Function> According to the automobile hood structure according to the present invention, a recess for housing the hood support rod is provided in the hood inner on the lower surface of the hood along the front-rear direction, and the hood support rod is rotatably attached to the recess. Therefore, the height of the hood relative to the front fender apron is lowered, increasing the degree of freedom in shaping the front of the vehicle body.

In addition, the rear end of the hood support rod is pivoted just behind the folding bead of the hood inner, and a stopper is provided to prevent the rear end of the hood support rod from moving rearward when the hood is closed. Rigidity behind the bead increases.

This improves the ability of the hood to bend in the event of a frontal collision, increasing safety.

Embodiment A preferred embodiment of the present invention will be described below with reference to FIGS. 1 to 6. Here, parts common to the conventional example are given the same reference numerals, and redundant explanations will be omitted.

20 is a hood, and 21 is a hood support rod. The hood support rod 21 is manufactured using a round bar, and its front end 21a is formed into a flat plate shape to form a fulcrum portion 2.
2, and the rear end 21b is bent into a crank shape. The fulcrum portion 22 is rotatably attached to a fulcrum clip 24 by a pin 23, and the fulcrum clip 24 is further attached inside a recess 26 provided in the hood inner 25 (see Fig. 3). .

When the hood is open, the hood support rod 21 hangs downward from the hood inner 25 and extends its rear end (lower end) 21b to the front fender apron (vehicle side) 27.
It engages with an engagement hole (fixing part) 28 provided in the. That is, the engagement hole 28 engages only the rearmost end 29 of the rear end 21b of the hood support rod 21 for positioning, and the bent portion 30 contacts the upper surface of the front fender apron 27 and serves as a fulcrum to support the hood 20. is maintained at a predetermined opening degree (see Figure 1).

On the other hand, when the hood is closed, the hood support rod 2
1 is fixed at a predetermined position near its tip within the recess 26 by a fixing clip 31 to prevent it from wobbling (see FIG. 4). In other words, the food support rod 21
When the hood is closed, the hood inner 2 is closed as shown in Figure 5.
It is stored in the recess 26 of No. 5. At this time, the rear end 21b of the hood support rod 21 is engaged with a stopper hole (stopper portion) 32 provided on the upper surface of the front fender apron 27 (see FIG. 1). That is, the rear end 21b of the hood support rod 21 is located in the stopper hole 32.
Since the rearmost end portion 29 of and a part of the bent portion 3o are fitted, forward and backward movement beyond the allowable amount is prevented.

In this way, since the hood support rod 21 is rotatably attached to the recess 26 provided on the lower surface of the hood 20, the distance between the hood inner 25 and the front fender apron 27 is only the clearance h described above (see FIG. 9). So,
The height of the hood 20 relative to the front fender apron 27 is reduced, increasing the degree of freedom in shaping the front portion of the vehicle body (see FIG. 5).

Further, the front end 21a of the hood support rod 21 is pivotally supported immediately behind the folding bead 4 of the hood inner 25, and the rear end 21b of the hood support rod 21 is supported when the hood is closed.
Since the stopper hole 32 is provided to prevent the hood from moving rearward, the rigidity of the hood 20 at the rear of the bending bead 4 is increased. Therefore, the hood bending performance in the event of a frontal collision is improved, increasing safety (see Figure 6).

Further, since the hood support rod 21 is securely fixed to the recess 26 by the fixing clip 31 when the hood is closed, no noise is generated due to vibrations of the vehicle body.

In addition, in the above embodiment, the hood support rod 21
An example is shown in which the rear end 21b is bent into a crank shape, and an engagement hole 2 is provided as a fixing part on the vehicle body side corresponding to the rear end 21b.
8 and a stopper hole 32 is shown as a stopper portion, but the present invention is not limited to this. That is,
Any material may be used as long as it performs the same function and does not increase the height of the hood inner 25. For example, a protrusion may be provided at the tip of a rod-shaped hood support rod, a hole corresponding to the protrusion may be provided on the vehicle body side, and a protrusion portion having a hole corresponding to the protrusion may be provided as a stopper portion.

Further, although the above description has been made regarding a front-opening type hood, the automobile hood structure according to the present invention can be applied to a rear-opening type hood in exactly the same manner.

<Effects of the Invention> The automobile hood structure according to the present invention has the content as described above, and includes a recess for storing the hood support rod on the underside of the hood, and the hood support rod is rotated in the recess. Because it can be mounted freely, the height of the hood relative to the front fender apron is lowered, increasing the degree of freedom in shaping the front of the vehicle body.

In addition, the hood support rod is pivoted just behind the folded bead of the hood inner, and a stopper part is provided to prevent the rear end of the hood support rod from moving rearward when the hood is closed. stiffness increases. This improves the ability of the hood to bend in the event of a frontal collision, increasing safety.
