Description

[Detailed Description of the Invention] <Industrial Application Field> The disclosed technology belongs to the technical field of vehicle roof structures.

Therefore, this invention is a roof structure for a so-called targatop car in which the roof panel is detachable, and the roof panel is divided into the front end side and the side part of the roof top, and the quarter panel of the body member is This is an idea for a roof structure of a vehicle in which a joint part with a stepped step is formed by increasing the L-shaped corner part.In particular, the corner part forming the increased drawing step is divided and formed as a reinforcing panel to form an integral part of the roof. In order to improve the processing accuracy during drawing forming, the reinforcing panel is provided with a reinforcing part that extends to a predetermined side over the joint part and in the width direction of the vehicle, and the reinforcing part is joined to the drawing forming surface of the roof body. This is an idea related to a vehicle roof structure with increased rigidity.

<Conventional technology> Conventionally, produced automobiles have been equipped with a convertible type vehicle in which the cabin canopy, that is, the roof can be opened and closed to provide a sense of openness when driving. They are divided into T-bar roofs, Targa tops, etc. depending on the shape of the roof, and Targa top cars have a better sense of openness than T-bar roof cars, but
There was a tendency for the strength to be inferior.

As shown in FIGS. 6, 7, and 8, in the case of a targa top type vehicle 1, the roof panel 2 can be removed and attached after the vehicle is completed, and the rear roof panel 3 can be attached to maintain the strength of the vehicle body. The strength of the vehicle had to be higher than that of ordinary automobiles.

Therefore, the rear roof 3 is used as a component of the body.
At the corner part 4 of the rear roof 3, which wraps around from the roof to the side, joint parts 6 and 7 are formed in an L-shape when viewed from the top of the vehicle, and the rear end of the roof panel 2 is attached to the corner part 4 of the rear roof 3, which wraps around from the roof to the side. 5
are joined.

<Problems to be solved by the invention> However, in the case of the rear roof 3 based on the above-mentioned conventional technology, it is necessary to increase the thickness of the plate in order to obtain strength at curved parts where stress occurs. However, as a result, the amount of drawing during processing and the number of steps generally increase, making it difficult to form.

Furthermore, as the plate thickness increases, the capacity of the press used for drawing must be increased, which has the disadvantage of increasing costs.

However, in the case of large panels, the increase in thickness not only increases the overall weight, but also has the disadvantage of significantly increasing the cost of the materials used.

Therefore, as an alternative to increasing the overall thickness of the rear roof 3, it has been desired to have a structure in which the strength can be particularly increased at the joint 7 with the quarter panel 5.

The purpose of this invention is to solve the problems of the vehicle roof structure based on the above-mentioned conventional technology, and to make it possible to increase the strength of the entire vehicle body without increasing the thickness of the rear roof. It is an object of the present invention to provide an excellent vehicle roof structure that will benefit the field of application of panel bonding technology.

<Means for solving the problem> In order to solve the above-mentioned problem, the structure of this invention, which is based on the above-mentioned claims for utility model registration, is continuous over the front end side and both sides. A joint portion having a drawn step and to which a removable roof panel and a quarter panel are respectively attached is formed with an increased drawn step at each corner portion of an L-shape in plan view on one side, and is arranged in the width direction of the vehicle. In the roof structure of a vehicle, the corner portion is divided into reinforcing panels and is provided with a reinforcing portion extending laterally by a predetermined amount to the joint portion and extending in the width direction of the vehicle, The vehicle roof structure is characterized in that the reinforcing portion is joined to the aperture forming surface of the roof body.

<Function> Thus, the rear roof, in which the joining part of the roof panel and the quarter panel is formed into an L-shape in plan view from the front end side to the side part, is divided into parts at the corners of the L-shape as reinforcing panels to form the main body. By joining to the quarter panel, the overall strength can be increased, and technical measures have been taken to increase the strength of the joint with the quarter panel while making it easier to mold each part.

<Example> Next, an example of this invention is shown in FIG. 6,
The explanation will be as follows based on FIGS. 1 to 5.

3' shown in FIG. 1 is the rear roof, which forms the gist of this invention, and is disposed at the top as a component of the vehicle body, and its corners allow it to extend toward the front end as indicated by the solid arrow. A joint 6' that locks the roof panel 2 is formed, and a joint 7' to which the quarter panel 5 is joined by welding is formed on the side indicated by the dashed arrow (for convenience of illustration, only one side will be explained). The joint portions 6' and 7' form an L-shape as shown in FIG.

Thus, the rear roof 3' has both joint parts 6',
The main panel 9, which is torn from a position 1 point below the intersection P of the rear roof 3' to the corner part 8, forms the corner part 8 and extends both joint parts 6' and 7' of the rear roof 3' to the side by a predetermined amount. A thick reinforcing panel 10 extending in the vehicle width direction and having an L-shaped reinforcing portion 10' of the reinforcing panel is welded and joined.

In this way, the rear roof 3' to which the reinforcing panel 10 is joined is a roof panel reinforcement to which the reinforcing panel 10 is joined via the bolts 11, as shown in FIGS. 12,
It is spot welded to the quarter panel 5 which is integrated with the roof side outer 13 and the quarter pillar inner 14.

15 is a quarter inner, 16 is a quarter panel inner, and 17 is a quarter panel inner. As shown in FIG. 5, the quarter panel 5, roof side outer 13, roof panel reinforcement 12, and quarter pillar inner 14 are bolts. 18.

Therefore, the main panel 9 and the reinforcement panel 10
As shown in Fig. 4, the rear roof 3' divided into two parts can be processed easily because the depth 1 required for drawing is less than the depth 2 of the conventional rear roof 3 shown in Fig. 8. In addition, since the reinforcing panel 10 is formed as a thick-walled member, the overall weight of the rear roof 3' remains almost unchanged.
Rigidity and strength can be significantly increased.

In particular, since the L-shaped portion 10' of the reinforcing panel 10 in the width direction of the vehicle 1 extends and has a wide joint, the strength of the joint with the quarter panel 5 of the rear roof 3' is high.

Furthermore, since the shape of the rear roof 3' is not changed as a whole, the mounting position with other panels is not affected, and conventional peripheral parts can be used.

<Other Embodiments> It goes without saying that the embodiment of this invention is not limited to the first embodiment described above, and for example, it can be applied not only to targa top type vehicles but also to T-bar roof type vehicles. Various aspects can be adopted.

<Effects of the invention> As described above, according to this invention, the overall rigidity of the vehicle roof is basically increased by increasing the strength of the parts where stress is concentrated without changing the overall panel thickness. This has the excellent effect of increasing the

In addition, by dividing the corner parts into reinforcing panels, it is possible to simplify the overall shape of each part, which is complicated due to deep drawing due to the joints of roof panels and quarter panels. Machining, etc. can be carried out smoothly, and the excellent effect of simplifying the machining process can be achieved.

Furthermore, since some of the reinforcing parts of the reinforcing panel extend in the width direction of the vehicle, the rigidity of the curved parts on both sides, which require increased strength, is increased.
This has the excellent effect of increasing the reliability of the body.

In addition, since the amount of each molding can be reduced by dividing the molding, productivity is improved and costs can be reduced.
