Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a vehicle roof structure, and more particularly, to a vehicle roof structure having a sliding roof to form a sunroof.

[Prior Art] In a vehicle roof structure of this type, as shown in FIG. 13, a rectangular opening 12 formed in a roof panel 10 is opened and closed by a sliding roof 14.
As shown in FIG. 20, the roof panel 10 is formed with a vertical wall surface 10B that extends downward from the end of the outer plate surface 10A around the opening 12 (actually 56-49622).
No. 57-45426, etc.). And the sliding roof 1
4, a weather strip 16 is provided on the outer periphery,
The weather strip 16 closes the opening 12 with the weather strip 16 pressed against the vertical wall surface 10B as shown in the figure.

The sliding roof 14 has its rear end moved downward (lift down) as shown by the imaginary line in the drawing from the state of the solid line closing the opening 12 and then slides backward to the lower side of the roof panel 10. It is designed to be stored in.
Also, after sliding forward from the stored state, the rear end portion moves upward (lifts up) to close the opening 12 as described above.

Therefore, at the rear end portion 12D of the opening 12 shown in FIG.
Vertical wall surface 10 in Fig. 20 to secure the required indoor height
The height dimension of B cannot be made too large. Also,
A corner portion 12A on the vehicle rear side where the rear end portion 12D of the opening 12 is continuous
Then, for the same reason as described above, the height dimension of the vertical wall surface 10B cannot be made too large, and at the same time, the press formability of the roof panel 10 must be taken into consideration.

FIG. 21 shows a structure in which the structure shown in FIG. 20 is applied to the corner portion 12A and corresponds to a cross-sectional view taken along the line AA of FIG.

With this structure, the shape of the roof panel 10 does not cause a problem in press formability, and the height dimension of the vertical wall surface 10B of the roof panel 10 should be as small as possible within a range in which a required sealing property is secured. Therefore, the required indoor height can be secured.

However, in this structure, as described above, when the sliding roof 14 is stored or when the opening 12 is closed from the stored state, the weather strip 16 slides on the lower end corners of the vertical wall surface 10B to form a coating film. Wears away and exposes the metal surface. Therefore, due to the effect of rainwater retained between the vertical wall surface 10B and the weather strip 16, the vertical wall surface is exposed from the exposed metal surface.
There was a problem that 10B would rust.

Reference numeral 18 in the drawing is disposed below the roof panel 10 and is joined to the roof panel 10 in the vicinity of the opening 12 so that the roof panel
It is a reinforcing plate that reinforces 10.

FIG. 22 shows a structure in which the structure disclosed in Japanese Utility Model Laid-Open No. 57-46016 is applied to the corner portion 12A. In this structure, an obtuse angle is formed from the lower end of the vertical wall surface 10B toward the opposite side of the opening 12. An inclined surface 10C that is bent and extends is formed.

Therefore, the weather strip 1 is attached to the lower end corner of the inclined surface 10C.
Since 6 does not come into sliding contact, abrasion of the coating does not occur, but slope 10C
Since the rainwater retained as described above flows down and adheres to and accumulates at the lower end of the, the problem of rusting cannot be solved.

FIG. 23 shows that the structure disclosed in Japanese Utility Model Publication No. 58-22819 is applied to the corner portion 12A and the sealing agent 20
It has a structure that uses both. That is, a lower vertical wall surface 10D extending parallel to the vertical wall surface 10B from the lower end of the inclined surface 10C is formed, and the lower vertical wall surface 10D and the reinforcing plate 18 are filled so as to fill the facing gap between the lower vertical wall surface 10D and the reinforcing plate 18. Sealant 2 across
0 is applied. Therefore, the sealing agent 20 solves the problem of rusting.

[Problems to be solved by the invention] However, in this structure, the height dimension becomes large due to the existence of the lower vertical wall surface 10D, and the ceiling height must be lowered, which causes a problem that the required indoor height cannot be secured. Occurs.

Moreover, since the length along the height direction from the end of the outer plate surface 10A to the lower end of the lower vertical wall surface 10D becomes long, it is necessary to increase the radius of curvature of the corner 12A in consideration of press formability. There is also a problem that the opening area of the opening 12 is reduced.

The height dimension of the vertical wall surface 10B that presses and abuts against the weather strip 16 must be large enough to secure the required sealing property, and the length along the height direction of the lower vertical wall surface 10D should also be shortened. If it is too much, the coating area of the sealant 20 is reduced and the coating workability is deteriorated. For this reason,
In the structure shown in FIG. 23, the height dimension and the lower limit of the length along the height direction are limited to themselves, and the occurrence of the above-described problems cannot be avoided.

In view of the above, the present invention prevents rusting of the end portion of the roof panel at the corner portion on the vehicle rear side of the roof opening that is opened and closed by the sliding roof, and is of a portion bent from the end portion of the roof panel outer plate surface. An object of the present invention is to provide a vehicle roof structure capable of suppressing the height dimension of the roof panel and the length along the height direction to such an extent that the above-mentioned problems do not occur.

[Means for Solving the Problems] In the vehicle roof structure according to the present invention, the roof panel is directed downward from the roof panel outer surface end at the vehicle rear corner of the roof opening opened and closed by the sliding roof. A reinforcing panel that is formed below the roof panel while forming a roof panel vertical wall surface that bends and extends and a roof panel inclined surface that bends and extends at an obtuse angle from the lower end of the roof panel vertical wall surface to the side opposite to the roof opening side. A reinforcing plate vertical wall which extends along the roof panel vertical wall and whose lower end projects downward from the intersection of the roof panel inclined surface with the extension line to the reinforcing plate side. It is characterized in that the sealing agent is applied to the portion projecting from the inclined surface of the panel and the vertical wall surface of the reinforcing plate.

[Operation] In the present invention, which is the above means, the reinforcing plate disposed below the roof panel extends along the vertical wall of the roof panel, and the lower end of the reinforcing plate extends from the intersection with the extension line of the inclined surface of the roof panel toward the reinforcing plate. Since the vertical wall of the reinforcing plate that protrudes downward is formed and the lower end of the roof panel is an inclined surface that is close to the vertical wall of the reinforcing plate, the sealing agent application work with the sealer gun that applies the sealing agent can be done by changing the roof panel inclined surface. The work becomes a guide surface and the work becomes easy. Also, when finishing the sealing agent with a spatula, the sealing agent is scraped off by the guides at the bent portion of the inclined surface of the roof panel and the lower end of the vertical wall surface of the reinforcing plate, so that the lower end of the inclined surface of the roof panel is not exposed. There is no worry of rusting.

In addition, since the roof panel has only the roof panel inclined surface extending on the vertical wall of the roof panel, the height dimension from the end of the roof panel outer plate surface to the roof panel inclined surface and the length along the height direction are as described above. It can be suppressed to the extent that such a problem does not occur.

[Embodiment] FIGS. 1 to 5 show an embodiment of a vehicle roof structure according to the present invention, which correspond to sectional views taken along the lines AA to EE in FIG. 13, respectively. Further, FIG. 6 corresponds to a partial perspective view of the periphery of the corner portion 12A of FIG. 13 as seen from the inside of the roof opening, and FIGS. 7A and 7B are exploded views of FIG. 8 is a perspective view, FIG. 8 is a view taken along the line VIII in FIG. 7 (A), and FIG. 9 is a sectional view taken along the line IX-IX in FIG.

The appearance of the roof structure of the present embodiment is basically the same as that of the conventional structure, and as shown in FIG. 13, the rectangular opening 12 formed in the roof panel 10 has a sliding roof 14.
It is designed to be opened and closed with.

Further, as shown in FIGS. 1 to 5, a roof panel vertical wall surface 32A formed by being bent downward from the end of the roof panel outer plate surface 30 is formed on the entire inner circumference of the opening 12. 32E
Is located.

Further, a reinforce 34 as a reinforcing plate is arranged below the roof panel 10. This Reinforth 34
An opening 35 is formed corresponding to the opening 12, and the roof panel vertical wall surface 32A is formed so as to form a peripheral wall of the opening 35.
Reinforce vertical wall 36A extending downward in parallel with ~ 32E
~ 36E is continuously formed. The reinforce 34 has a reinforce lateral wall surface 37 continuous with the upper ends of the reinforce vertical wall surfaces 36A to 36E and is joined to the lower surface of the roof panel outer plate surface 30 with an adhesive in the vicinity of the opening 12.

FIG. 2 corresponds to a sectional view taken along the line BB of FIG. 13, and shows a roof structure at the front end portion of the opening 12. In this portion, the reinforce vertical wall surface 36B slightly projects from the lower end of the roof panel vertical wall surface 32B. These roof panels vertical wall 32B
The reinforce vertical wall surface 36B is welded by spot welding (welded portion is indicated by reference numeral 42). In addition, from the lower end of the roof panel vertical wall surface 32B to the reinforce vertical wall surface 36B.
A sealer 38 as a sealant is applied over the area.

FIG. 3 corresponds to a sectional view taken along the line CC of FIG. 13 and shows a roof structure at the vehicle front corner of the opening 12. Even in this part, the reinforce vertical wall 36C is the roof panel vertical wall 32C.
It slightly protrudes from the lower end of the
Has been applied. However, since it is a corner portion, the height dimension of the roof panel vertical wall surface 32C is set smaller than that at the front end portion of the opening 12 in consideration of press formability, and accordingly, the reinforce vertical wall surface 36
The height dimension of C is also set small.

In this embodiment, the sliding roof 14 is of a tilt-and-slide type in which the opening 12 can be opened by sliding to the rear of the vehicle and the rear end can be flipped up by tilting up. Therefore, when the sliding roof 14 is tilted up as shown by imaginary lines in FIGS. 2 and 3, the weather strip 40 attached to the outer peripheral portion of the sliding roof 14 has a roof panel vertical wall surface 32.
It will slide down to B and 32C and move downward.

Even when the sliding roof 14 is tilted up in this way, the weather strip 40 does not have the spot weld 42 or the sealer 38.
There is no sliding contact with the coating part.

FIG. 4 corresponds to a sectional view taken along the line DD of FIG. 13, and shows a roof structure at the rear end of the opening 12. In this portion, the roof panel 10 has a roof panel rising slope 44 that is bent at an acute angle from the lower end of the roof panel vertical wall surface 32D toward the side opposite to the opening 12. Further, a roof panel lateral wall surface 46 that is bent at an obtuse angle from the upper end of the roof panel rising slope 44 toward the side opposite to the opening 12 and is parallel to the roof panel outer plate surface 30.
Are formed.

In the reinforce 34, the reinforce vertical wall surface 36D abuts the roof panel vertical wall surface 32D, and is sandwiched between the roof panel outer plate surface 30 and the roof panel horizontal wall surface 46. Also, from the rear end of the roof panel side wall surface 46, reinforce
Sealer 38 is applied to 34.

At the rear end of the opening 12, the sliding roof 14 passes downward when it slides backward after being lifted down as shown by the imaginary line in the figure, so the height dimension of the roof panel vertical wall surface 32D is set small. Along with this, the height dimension of the reinforce vertical wall surface 36D is also set small.

Further, even when the sliding roof 14 is lifted down as described above, the weather strip 40 does not make sliding contact with the sealer 38.

FIG. 5 corresponds to a sectional view taken along the line EE of FIG. 13 and shows a roof structure at the side end portion of the opening 12. In this portion, the height dimension of the roof panel vertical wall surface 32E is set to be substantially equal to the roof panel vertical wall surface 32A at the front end of the opening 12, and the reinforce vertical wall surface 36E is a length slightly protruding from the lower end of the roof panel vertical wall surface 32E. The sealer 38 is applied from the lower end of the roof panel vertical wall surface 32E to the reinforce vertical wall surface 36E. Further, similarly to the front end portion of the opening 12, the roof panel vertical wall surface 32E and the reinforce vertical wall surface 36E are welded by spot welding (welding portion 42).

It should be noted that even when the sliding roof 14 is lifted down as shown by the imaginary line in the drawing, the weather strip 40 does not slidably contact the spot welding portion 42 or the coating portion of the sealer 38.

FIG. 1 corresponds to a cross-sectional view taken along the line AA of FIG. 13, and shows a roof structure in the vehicle rear side corner portion 12A of the opening 12. In this portion, the roof panel vertical wall surface 32A is smaller in height than the roof panel vertical wall surface 32D at the rear end of the opening 12 (see FIGS. 6 to 8). Counter opening 12 from the lower end of the vertical wall 32A
Roof panel descending slope 48 bent at an obtuse angle to the side
Are formed. The total height dimension of the roof panel vertical wall surface 32A and the roof panel descending inclined surface 48 is slightly smaller than the height dimension of the roof panel vertical wall surface 32D at the rear end of the opening 12 (see FIG. 6). ).

The vertical wall 32A of the roof panel faces the side end of the opening 12 without changing the above-mentioned height dimension from the continuous part with the rear end of the opening 12, but as the distance approaches the side end of the opening 12, the height increases. The height dimension increases and extends downward to be continuous with the roof panel vertical wall surface 32E at the side end portion of the opening 12. The roof panel descending inclined surface 48 was slightly separated from the position where the roof panel rising inclined surface 44 at the rear end of the opening 12 became shorter and disappeared as it approached the vehicle rear corner of the opening 12. The extension is started at the position, and the roof panel vertical wall surface 32A disappears just before the roof panel vertical wall surface 32E on the side of the opening 12 is continuous.

Further, at the vehicle rear side corner portion of the opening 12, the reinforce vertical wall surface 36A is set to have a length slightly protruding from the lower end of the roof panel descending inclined surface 48. This reinforce vertical wall surface 36A is continuous from the reinforce vertical wall surface 36D at the rear end of the opening 12 without changing the height dimension, and the roof panel vertical wall surface 32A corresponds to increasing the height dimension from the middle as described above. Then, the height dimension is increased, and the height dimension is continuous with the reinforce vertical wall surface 36E at the side end portion of the opening 12.

The roof panel descending inclined surface 48 and the reinforce vertical wall surface 36A maintain the same positional relationship as shown in FIG. 9 even in the height dimension changing portion.

Further, the continuous portion of the reinforce vertical wall surface 36A and the reinforce vertical wall surfaces 36D, 36E is bent in a stepwise manner to form a step surface 39.

At the corner of the opening 12 on the vehicle rear side, the lower end of the roof panel descending inclined surface 48 and the reinforce vertical wall surface 36A.
A sealer 38 is applied to the sealant 38, and the sealer 38 is continuous with the sealer 38 applied at the rear end portion, the side end portion, the front corner portion and the front end portion of the opening 12 in a strip shape.

Since the sealer 38 does not project to the vertical wall surface 32A of the roof panel at the rear corner of the vehicle, the sliding roof 1
Even when 4 is lifted down as shown by the imaginary line in the drawing, the weather strip 40 does not slide.

As described above, according to the present embodiment, the sealer 38 is applied also to the vehicle rear side corner portion of the opening 12, so that the sealer 38 is applied over the entire circumference of the opening 12 to completely prevent rusting in the opening 12. It can be prevented all around.

According to the present embodiment, the coating workability of the sealer 38 at the vehicle rear side corner portion of the opening 12 is good, and troubles are unlikely to occur in the sealer 38.

That is, in the above-described roof structure of FIG. 23, when applying the sealant 20 with the sealer gun 22 as shown in FIG. 14, it is a work using a line along the lower end corner of the lower vertical wall surface 10D as a guide. , Workability is poor. Furthermore, as shown in FIG. 15, when finishing the applied sealant 20 with a spatula 24, the end portion 10DD of the roof lower vertical wall 10 and the reinforce
Since the end portion 18DD of 18 is scraped off by the guide, as shown in FIG. 16, the end portion 10DD of the lower vertical wall 10 of the roof is easily exposed, and if exposed, it may cause rust.

On the other hand, in the present embodiment, as shown in FIG. 17, the application of the sealer 38 by the sealer gun 22 is an operation using the roof panel descending inclined surface 48 as a guide surface, which facilitates the operation. Also, when the sealer 38 is finished with the spatula 24 as shown in FIG. 18, the sealer 38 has the bent portion 32AA and the end portion 3 of the reinforce vertical wall surface 36A as shown in FIG.
Since 6AA is scraped off by the guide, the end 48AA of the roof panel descending inclined surface 48 is not exposed, and there is no risk of rusting.

10 to 12 show the main parts of a modification of the above-described embodiment, and in this roof structure, a part of the vehicle rear side corner portion of the opening 12 is different from that of the above-mentioned embodiment.

That is, the roof panel vertical wall surface 32A has a roof panel vertical wall surface 3
A step surface 41 is formed by bending in a stepwise manner in the height direction from a portion where the height is increased as it approaches 2E. Instead, the descending inclined surface 48 is not formed in this portion and the roof panel vertical wall surface 32A is formed. The lower part of is parallel to and faces the reinforce vertical wall 36A. A sealer 38 is applied from the lower end of the roof panel vertical wall surface 32A to the reinforce vertical wall surface 36A.

In this roof structure, the sealer 38 is the vertical wall 32A of the roof panel.
The sealer 38 is located on the stepped-down part, so that the weather strip is lifted even when the sliding roof 14 is lifted down as shown by the phantom line in FIG. The 40 does not slide against the sealer 38.

[Effects of the Invention] As described above, in the vehicle roof structure according to the present invention,
At the vehicle rear corner of the roof opening that is opened and closed by the sliding roof, the roof panel edge is prevented from rusting, and the height of the roof panel at the portion bent from the roof panel outer surface edge and The length along the height direction can be suppressed to the extent that the required indoor height cannot be secured or the roof opening area is reduced, and at the same time the sealing agent application work is facilitated. Has excellent effect.
