[0002]

An opening / closing member such as an engine hood or a trunk lid is provided with an outer panel and an inner panel which is wound around and coupled to a peripheral portion of the outer panel and is arranged below the outer panel with a space therebetween. It is arranged so as to be openable and closable in the vertical direction at the front and rear openings of the vehicle body via a hinge member.

The hinge member is fastened and fixed to the lower surface of the inner panel by bolts and nuts as fastening members, and the ends of the bolts and nuts project into the space between the outer panel and the inner panel, so that the outer panel is secured. When it receives an external force from above and bends downward, it may hit the ends of the bolts and nuts and locally deform.

Therefore, according to the present invention, when the outer panel receives an external force and bends downward, a cushioning effect is obtained in this deformation process, and it is possible to avoid directly hitting the end portion of the fastening member. The opening and closing body of the.

[0005]

According to a first aspect of the present invention, there is provided an outer panel and an inner panel which is connected to a peripheral edge portion of the outer panel and is spaced apart from the lower side of the outer panel. In an opening / closing body that is openably / closably arranged in the front and rear openings of a vehicle body via a hinge member fixed by a fastening member, in an air gap between the outer panel and the inner panel, and from the inner panel to the air gap. A cushioning member is arranged so as to cover the end of the projecting fastening member , and this cushioning member is used as a hinge member arrangement portion of the inner panel.
Panel material bonded to the reinforcement provided on the upper surface of the
And the panel material is a joint with the reinforcement.
The end of the fastening member that is formed from the

It is characterized by having a visor.

[0006]

[0007] In the second aspect, the panel member according to claim 1, is characterized by having an increased thickness than the outer panel.

[0008]

According to the first aspect of the present invention, when the weight is applied to the portion directly above the hinge member disposition portion of the opening / closing body due to the weight of the outer panel, since the outer panel is relatively thin, the outer panel bends downward. However, since the cushioning member is arranged so as to cover the end portion of the fastening member protruding into the gap between the outer panel and the inner panel, the outer panel comes into contact with the cushioning member in the process of flexing and deforming, and the flexing is suppressed. Since the outer panel is prevented from directly hitting the end of the fastening member, it is possible to prevent the outer panel from being locally deformed, and the outer panel abuts on the end of the fastening member to give a rigid feeling. It is possible to avoid the occurrence and to further improve the sense of quality.

Further, when a human body collides with a portion directly above the hinge member disposition portion of the opening / closing body and the outer panel is bent and deformed downward, the cushioning member can absorb the collision energy, and the end portion of the fastening member can locally absorb the collision energy. The impact can be avoided and the safety can be further enhanced.

Moreover , since the cushioning member is formed of the panel material joined to the reinforcement, the plate thickness of the panel material, the rising angle of the eaves covering the end portion of the fastening member, and the outer panel and the end portion of the fastening member. The amount of collision energy absorption can be easily adjusted by the height at which the eaves are arranged.

Further, since the panel member as the cushioning member can be joined to the reinforcement to be sub-assembled, the cushioning member can be easily arranged, and the reinforcement of the hinge member is partially mounted so that the hinge member has a mounting rigidity. Can be increased.

According to the second aspect, in addition to the effect of the first aspect, since the panel material as the cushioning member has a larger plate thickness than that of the outer panel, the external force acting from above the outer panel is relatively small. With this panel material, the downward bending deformation of the outer panel can be restricted to the height position where the eaves are arranged, and the sticky feeling and plastic deformation of the outer panel can be eliminated and the quality feeling can be further enhanced.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings, taking an engine hood as an example of an opening / closing body.

1 to 3, reference numeral 1 denotes an engine hood as an opening / closing body, which is wound around and coupled to an outer panel 2 and a peripheral portion of the outer panel 2 and is disposed below the outer panel 2 with an appropriate interval. And the inner panel 3 that is formed.

The outer panel 2 and the inner panel 3 are
In each case, a steel plate material having a relatively thin plate thickness of, for example, about 0.6 mm is used so as not to impair the function of the monocoque body.

A hood hinge 4 as a hinge member is provided on both lower surfaces of the rear end portion of the inner panel 3 and a pair of front and rear bolts 5 are provided.
Further, the opening / closing body 1 is fastened and fixed by a nut 6, and the opening / closing body 1 is arranged via the hood hinge 4 so as to be vertically openable and closable on both side edges of an opening of an engine room which is a front opening of the vehicle body (not shown). Is done.

A reinforcement 7 is joined and arranged by spot welding on the inner surface (upper surface) of the hood hinge mounting portion of the inner panel 3 so as to be reinforced. In the present embodiment, the nut 6 is joined onto the reinforcement 7. The bolts 5 are screwed into the nuts 6 from the lower surface side of the inner panel 3 to fasten and fix the hood hinges 4.

A buffer member 8 is provided in the space between the outer panel 2 and the inner panel 3 so as to cover the end of the bolt 5 protruding from the inner panel 3 into the space.

In this embodiment, a panel material having a larger plate thickness than the outer panel 2, for example, a strip-shaped steel plate panel material having a plate thickness of 1.6 mm is used as the buffer member 8, and the panel member 8 has an intermediate portion. Is joined by spot welding on the reinforcement 7 between the front and rear nuts 6 and 6, and the eaves are formed to rise from the front and rear portions of this joint portion and extend in the front-rear direction substantially parallel to the outer panel 2 and the inner panel 3. The portions 9 and 9 are arranged to cover the ends of the bolts 5 and 5 between the ends of the bolts 5 and 5 and the outer panel 2.

According to the structure of the above embodiment, when the weight is applied to the engine hood 1 just above the portion where the hood hinge 4 is arranged by putting a hand on the outer panel 2,
Bends downward because the plate thickness is relatively thin, but covers the end portion of the bolt 5 projecting into the gap between the outer panel 2 and the inner panel 3 to cover the end portion 9 of the panel material 8 as a cushioning member.
Since the outer panel 2 is provided, the outer panel 2 is prevented from coming into contact with the eaves portion 9 in the process of flexing and deforming downward to suppress the flexure and directly hit the end portion of the bolt 5. It is possible to prevent 2 from hitting the end of the bolt 5 and locally deforming it, and avoiding a rigid feeling due to the outer panel 2 hitting the end of the bolt 5, thereby improving the quality. It can be further improved.

When the human body collides with the portion directly above the hood hinge 4 of the engine hood 1 and the outer panel 2 is bent and deformed downward, the eaves 9 is bent and deformed to absorb the collision energy. At the same time, since the eaves portion 9 covers the end portion of the bolt 5, local impact by the end portion of the bolt 5 can be avoided and the safety can be further enhanced.

In particular, by using a panel material as the cushioning member 8 as in the present embodiment, the plate thickness of the panel material 8, the rising angle of the eaves portion 9 and the distance between the outer panel 2 and the end portion of the bolt 5 are increased. The amount of collision energy absorption can be easily adjusted by the height of the eaves 9 and the like.

Moreover, the panel material 8 as this cushioning member
Since the plate thickness is larger than that of the outer panel 2, when the external force acting from above the outer panel 2 is relatively small, the outer panel 2 is flexed and deformed downward by the panel member 8 and the height of the eaves 9 is increased. The outer panel 2
The sticky feeling and plastic deformation can be eliminated, and the quality feeling can be further enhanced.

Further, in addition to such a cushioning effect, the panel material 8 as a cushioning member can be joined to the reinforcement 7 to be sub-assembled, so that the cushioning member 8 can be easily arranged and the reinforcement 7 can be formed. Since the multi-panel is partially formed, the mounting rigidity of the hood hinge 4 can be increased.

In the above embodiment, the nut 6 is joined and arranged on the upper surface of the reinforcement 7 so that the end portion of the bolt 5 projects into the space between the outer panel 2 and the inner panel 3. On the contrary, as shown in FIG. 4, the head 5a of the bolt 5 is welded and fixed to the upper surface of the reinforcement 7, and the nut 6 is screwed to the end of the bolt 5 which penetrates the inner panel 3 and projects to the lower surface. If the hood hinge 4 is fastened and fixed, only the bolt head 5a protrudes into the gap, so that the distance between the bolt head 5a and the eaves 9 can be increased, and the eaves 9 can be deformed. Because the stroke can be increased,
The amount of collision energy absorption can be expanded.

Although the engine hood is shown as the opening / closing body in the above embodiment, the same effect as described above can be obtained by applying the engine hood to the trunk lid.

As the cushioning member 8, in addition to the above-mentioned panel material, a block body made of an elastic material such as rubber or synthetic resin can be used.
