Description

Description: TECHNICAL FIELD The present invention relates to an automobile lid structure, and more particularly to a lid structure that is a bonnet.

(Prior Art) As is well known, in an automobile such as a passenger car, an opening in a front portion of a vehicle body, which is generally an engine room, is covered with a lid, and the lid serves as a so-called hood. This lid is generally formed by joining an outer panel and an inner panel, and in most cases, a lid lock striker is attached to the front end portion. On the other hand, recently, many automobiles equipped with retractable headlamps are provided, but in such automobiles, the lid is formed in a shape in which front ends of both side portions corresponding to headlamp mounting positions are removed. In such a lid, an extension portion that extends toward the front side of the vehicle body is formed in the center portion of the front end (that is, the portion between the portions removed as described above), and the above striker is attached to this extension portion. Further, it has been recognized that the rigidity of the extension is insufficient and the extension is easily deformed.
In particular, when the outer panel and the inner panel of the lid are formed of aluminum plates in order to reduce the weight of the vehicle body for the purpose of improving fuel efficiency, the above-mentioned problems are likely to occur.

Therefore, as disclosed in, for example, Japanese Patent Laid-Open No. 185378/1983, it has been considered to reinforce the extension portion by a lid lock device mounting reinforcement force, but still, a sufficient rigidity improving effect is not obtained. is the current situation.

(Object of the Invention) The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a lid structure for an automobile capable of sufficiently increasing the rigidity of the extension of the front end of the lid. is there.

(Structure of the Invention) The structure of the lid of the automobile of the present invention comprises an outer panel and an inner panel joined to each other, the extension portion is formed at the front end portion, and the attachment portion is attached to the extension portion by striker reinforcement. In a lid to which a striker for lid lock is reinforced and attached, a closed cross section is formed by the outer panel and the inner panel at the front part of the lid including the extension, and the closed cross section is separated from the striker reinforcement. Of the reinforcement, the rear end of the reinforcement is joined to the joint of the two panels behind the mounting portion of the striker, and the front end is in front of the front mounting portion of the striker, The inner panel near the joint between the outer panel and the inner panel at the front end of the extension I joined, and both side ends is characterized in that it has joined respectively to said inner panel near the junction between the outer panel and the inner panel in the both end portions of the extension portion.

(Example) Hereinafter, the present invention will be described in detail based on an example shown in the drawings.

1, 2 and 3 show a lid structure of an automobile according to an embodiment of the present invention. FIG. 1 shows a plan view of the lid 11 of the automobile 10 shown in FIG. 4, and FIGS. 2 and 3 show II-II line and III-III line of FIG. 1, respectively.
The vertical cross-sectional shape in the line direction is shown. The lid 11 covers the opening 12 at the upper part of the engine room in the case of an engine front-mounted type vehicle, and as shown in FIG. 1, its left and right rear end portions (base end portions). Are rotatably attached to the vehicle body via hinges 13L and 13R, respectively.

As shown in FIGS. 2 and 3, the lid 11 is formed by joining an outer panel 14 and an inner panel 15, but in this example, in order to reduce the weight of the vehicle body, both of these panels 14, 15 are joined.
Is formed of an aluminum plate. The inner panel 15 and the outer panel 14 provided with the openings 16 for reducing the weight are joined to each other by hemming at the peripheral portion (see FIGS. 2 and 3), and the other portions are joined together, for example, with a filler. Has been done. And inner panel 15
Is shaped so as to be separated from the outer panel 14 at an appropriate position, whereby the inner panel 15 and the outer panel 14 form a closed cross section, and the rigidity of the lid 11 is enhanced. Further, the front ends of both sides of the lid 11 are removed, so that the lid 11 has a shape having an extension 11a at the center of its front end. Headlamps 17L, 17R of automobile 10
Are arranged so as to be located outside the extension portion 11a when the lid 11 is closed, that is, in the portions removed as described above. These headlamps 17L and 17R are of a so-called retractable type, and are selectively set to either the storage state shown in FIGS. 1 and 4 or the use state in which the lamps are upright.

As clearly shown in FIG. 2, an outer panel 14 and an inner panel 15 are provided on the front portion of the lid including the extension portion 11a.
The closed cross-section portions 18 and 19 are formed by and. Closed cross section 18
A striker reinforcement 20 is disposed inside, and a lid lock striker 21 is fixed to the reinforcement 20 by welding, for example. The striker 21 engages with the lock member 30 on the vehicle body side when the lid 11 is closed to lock the lid 11 in the closed state. The outer panel 14 is provided in the closed cross-sections 18 and 19.
The reinforcements 22 are arranged along the inner surface of the. This reinforcement 22 has an outer panel 1
4. Like the imper panel 15, it is made of an aluminum plate, and its front end is joined to the inner panel 15 in front of the mounting portion of the striker 21, for example, by spot welding or via a filler. Further, the rear end of the reinforcement 22 is joined to both the panels 14 and 15 at the joining portion between the outer panel 14 and the inner panel 15 behind the attachment portion of the striker 21 via a filler, for example. The reinforcement 22 is joined to both the panels 14 and 15 together with the striker reinforcement 20 between the closed cross-sections 18 and 19 through a filler, for example. Further, as shown in FIG. 3, both ends of the reinforcement 22 are joined to the inner panel 15 in the vicinity of the joint portion of both panels 14 and 15 by spot welding or via a filler. The rear end of the striker reinforcement 20 is joined to the inner panel 15 by spot welding, for example.

As described above, the front portion of the lid 11 may not be provided with the two closed cross-section portions 18 and 19 arranged in the vehicle front-rear direction, but only one closed cross-section portion may be provided. Further, the panels 14 and 15 may form a further closed cross section on the rear side of the closed cross section 19 to further increase the rigidity of the front portion of the lid.

As described above, in the automobile lid structure of the present invention, the outer panel and the inner panel form a closed cross-section in a portion including the extension of the front of the lid, and the closed cross-section is formed in the closed cross-section. The reinforcement is arranged, and the front end of this reinforcement is joined to the inner panel near the joint between the outer panel and the inner panel at the front end of the extension, in front of the front closing part of the striker, Since the both ends are respectively joined to the inner panel near the joint between the outer panel and the inner panel at the both end portions of the extension, the front part of the lid is entirely reinforced by the reinforcement. , Its rigidity is greatly enhanced.

The lid structure of the present invention is not limited to a lid made of an aluminum plate in particular, and can be applied to a lid made of other general steel plates. It is particularly effective when applied to a lid made of boards.
