Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a vehicle roof structure.

(Prior art) Conventionally, as a vehicle roof structure, for example,
As disclosed in Publication No. 45321, the roof panel is provided with an opening that opens upward, and an outer member that slides from the outside (upper) side of the roof panel toward the rear, that is, toward the rear window, is provided in the roof panel. A vehicle is equipped with a sliding type sliding roof, and by sliding the sliding roof rearward (towards the rear window), the opening of the roof panel can be opened according to the feeling of openness desired by the occupants. Are known. A slider member is provided at the front side edge of the sliding roof and is slidably fitted to a guide rail provided at the side edge of the roof panel, so that when the sliding roof is opened, The sliding roof is supported by the side edge of the roof panel via a slider member that fits into the guide rail.

(Problem to be Solved by the Invention) As described above, the sliding roof can be used in a vehicle of the type that has a rear window installed in the back door or a trunk lid that is installed behind the rear window. When installed on a notchback (e.g. 3-box) type vehicle, a sliding roof that slides backwards when opened may interfere with the back door or trunk lid when opened, and the roof panel may be moved only through the slider member. Since the slide-in roof is supported by the side edges, the support rigidity of the slide-in roof for the roof panel is low, and the rigidity of the roof panel itself is also low. Therefore, by keeping the amount of rearward sliding movement of the sliding roof small, the sliding roof that has slid rearward when opened does not interfere with the back door or trunk lid when opened, and the longitudinal length of the slider member is It is necessary to increase the supporting rigidity of the slider member to the roof panel and the rigidity of the roof panel itself by increasing the distance between the support points of the slider member in the longitudinal direction with respect to the side edge of the roof panel. . However, since the above-mentioned conventional system is constructed based on the above-mentioned viewpoint, the opening area of the opening in the roof panel that opens with the amount of movement of the sliding roof naturally becomes small, which makes it difficult for the occupants. There is a problem in that it is not possible to secure an opening area sufficient to satisfy the desired sense of openness.

The present invention has been made in view of the above, and its purpose is to prevent the sliding roof from interfering with the back door or trunk lid when opened, and to fix the sliding roof at a position where it does not interfere with the back door or trunk lid when opened. By doing so, the amount of rearward sliding movement of the sliding roof is increased to ensure an opening area of the roof panel opening sufficient to satisfy the feeling of openness required by the occupants.

(Means for Solving the Problems) In order to achieve the above object, the solving means of the present invention provides a roof panel with an opening that opens upward, a sliding roof in the opening, and a sliding roof that is connected to the roof panel. The roof structure of the vehicle is such that the outer side of the vehicle slides rearward. A fixing part is provided for supporting at least a part of the sliding roof so as to be able to rotate rearward and downward when the sliding roof is completed rearward, and for fixing the rotating part to a rear window portion behind the roof panel. It is structured as follows.

(Function) With the above configuration, in the present invention, the outer side of the roof panel (
At least a part of the outer slide type sliding roof whose upper) side is slid rearward is a slider member slidably fitted to a guide rail provided at the opening side edge of the roof panel, for example. It is designed to rotate backwards and downwards using the fulcrum as a fulcrum.

In that case, at least part of the sliding roof
A hatchback with a rear window attached to the back door (
When the rotating part is rotated downward along the rear window part of a 2-box) type car or a notchback (3-box) type car with a trunk lid installed behind the rear window, the rotating part is rotated by the fixed part. Fixed. For this reason, if a sliding roof is applied to a hatchback type vehicle, the sliding roof (rotating part) will rotate vertically when the hatchback is opened when the sliding roof is completed rearward, whereas the notchback type When applied to an automobile, at least a portion (rotating portion) of the sliding roof that protrudes rearward of the roof panel when the rearward slide is completed will not interfere with the trunk lid when it is opened.

Further, the sliding roof is supported via a slider member whose front end is slidably fitted to the guide rail of the roof panel, and when at least a portion of the sliding roof completes rearward sliding. Since the rotating part of the sliding roof (the part that protrudes rearward beyond the roof panel) is fixed to the rear window part by a fixed part, the slide-in roof is supported by the side edge of the roof panel only through the slider member. The sliding roof has a higher supporting rigidity for the roof panel than the conventional sliding roof, and the rigidity of the sliding roof itself is increased.

Next, the operation of the above embodiment will be explained. First, a switch provided on the side of the vehicle interior 9, which is the inner surface side of the interior material 10 in the vehicle interior 9, is operated to open the sliding roof to open the motor 2.
When the drive shaft 25 of No. 4 is rotated forward (clockwise), the slider portion 2 of the slider member 27 is rotated via the wire cable 22.
9 is pulled rearward, each first pin member 33 of the slider section 29 moves within the first and second elongated holes 31 and 32 of the lifter section 30, and the lifter section 30 is tilted forward. Accordingly, the support member 34 tilts forward, and as shown by the imaginary line (two-dot chain line) in FIG. 3, only the rear end of the sliding roof 12 is lifted, and the sliding roof 12 is held in the tilted-up state. . Thereafter, the slider portion 29 is pulled rearward while sliding within the slider guide groove 28 of the first guide rail member 21, and along with this slider portion 29, the support pin member 3 via the second pin member 39 is pulled.
5 (support member 34) is pulled rearward while sliding within the support pin guide groove 36, as shown by the solid line in FIG.
The sliding roof 12 slides rearward above the roof and is guided to an open position similar to the conventional one, and in this state, a spoiler effect is obtained by the sliding roof 12. Then, by pulling out the second pin member 39 in this state to free the connection relationship between the lifter part 30 and the support member 34, the support pin member 35 is moved to the second guide as shown by the solid line in FIG. The sliding roof 12 slides in the groove 41 of the rail member 42.
The protrusion member 43 moves further rearward and rotates rearward and downward using the support pin member 35 as a fulcrum at the rear end of the groove portion 41, and floats upward when passing the stepped portion 41a from within the second guide rail member 42. The sliding roof 12 is fixed to the rear window glass 6 by a fixing portion 46 that fits into a fitting member 44 on the side edge of the back door 7.

Therefore, in the above embodiment, the outer slide type sliding roof 12 in which the outer (upper) side of the outer panel 4 of the roof 2 is slid rearward,
Left and right side edges 2c of the roof 2.

The support pin member 35 of the support member 34 sliding in each groove 41 of the second guide rail member 42 provided on the outer panel 4 of 2d is used as a fulcrum to rotate downward (backward downward) or upward. ing.

In that case, the sliding roof 12 is fixed by the fixing part 46 that fits into the fitting member 44 on the side edge of the back door 7 by the protruding member 43 while rotating rearward and downward along the rear window glass 6. ing. Therefore, when sliding roof 1 is completed rearward,
2 (rotating part) rotates in the vertical direction as the back door 7 is opened, and the sliding roof 12 that protrudes to the rear of the roof 2 when opened does not interfere with the back door 7 when opened. .

Further, the sliding roof 12 has a front end that is connected to the roof 2.
The left and right side edges 2c and 2d of the outer panel 4 are supported via support pin members 35 of a support member 34 that is slidably fitted into each groove 41 of the second guide rail member 42 on the outer panel 4. , when the sliding roof 12 (rotating part) completes rearward sliding, the rear part (the part that protrudes rearward from the roof panel) of the sliding roof 12 (rotating part) is attached to the fitting member 44 of the side edge part (rear window part) of the back door 7 with a protruding member. Since the sliding roof 12 is fixed by the fixing part 46 that fits into the roof panel 43, the sliding roof 12 is fixed to the roof 2, compared to a slide-in roof that is supported on the side edge of the roof panel only through the slider member. In addition to increasing the support rigidity, the sliding roof 12 is supported between two points in the front and back (up and down).
The rigidity and strength of 2 itself will be increased.

As a result, the amount of movement of the sliding roof 12 becomes large, and along with the amount of movement of the sliding roof 12, the opening area of the opening 11 of the roof 2 becomes large, providing the feeling of openness desired by the occupants. It is possible to secure a sufficient opening area to meet the requirements.

(Second Embodiment) FIGS. 17 to 21 show a second embodiment of the present invention,
In this second embodiment, the sliding roof 12 is applied to a notchback (three-box) type automobile in which a trunk lid is provided behind the rear window glass 6. Note that the same parts as in the above embodiment are given the same reference numerals, and detailed explanation thereof will be omitted.

That is, in this example, the sliding roof 12 is configured with a steel roof 51 made of a steel plate located on the front side, and a glass roof 52 made of tempered glass located on the rear side. An abbreviated first hinge member 53. A second hinge member 54 having a substantially U-shaped cross section is attached to the left and right positions of the rear end of the steel roof 51 (only the right side of the vehicle body is shown in the figure).
Fasten with bolts 55.55. And the above first
Both hinge members 53 and 54 are made rotatable by a hinge pin 56 that passes through the front position of the lower end of the hinge member 53 and the front position of the second hinge member 54, respectively. Furthermore, the rod member 58 is biased outwardly (towards both hinge members 53 and 54) by a spring 57, so that the rear position of the lower end of the first hinge member 53 and the rear position of the second hinge member 54 are It can be penetrated freely by

A lever 59 is provided at the inner end of the rod member 58 and projects downward from approximately the middle of the rear end of the steel roof 51, that is, toward the vehicle interior 9 side.

In this case, by pulling the lever 59 in the direction of compression against the biasing force of the spring 57 (in the direction of the arrow shown in the figure), the rod member 58 is pulled out from the first hinge member 53 and the first hinge member 53 is The glass, which is at least a part of the sliding roof, is rotatable downward around the hinge pin 56 with respect to the second hinge member 54 and, along with the first hinge member 53, protrudes to the rear of the roof panel when the rearward slide is completed. The roof 52 (rotating part) is
It is fixed by a fixing part 46 that rotates rearward and downward and fits into a fitting member 44 on the rear surface of a quarter pillar 45 on the side edge of the rear window glass 6 (vehicle body 1 side), which is part of the rear window glass 6, by means of a projection member 43. This will avoid interference with the trunk lid when the trunk lid is opened.

Furthermore, since the steel roof 51 is fixedly supported above the rear portion of the roof 2 in this state, a spoiler effect can be obtained by the steel roof 51.

Note that this example also has the same functions and functions as the first example above.
Effects can be obtained.

(Effects of the Invention) As described above, according to the vehicle roof structure of the present invention, a hatchback (two-box) type automobile in which the rear window is provided on the back door or a notchback type automobile in which the trunk lid is provided behind the rear window. At least a portion of the sliding roof that protrudes rearward from the roof panel along the rear window of a (3-box) type vehicle is rotated downward and fixed by a fixed part, so that it does not slide rearward. The sliding roof when completed does not interfere with the hatchback or trunk lid when opened, and the rotating part of the sliding roof, which is especially applied to hatchback type cars, rotates as the hatchback is opened, making it possible to Application to automobiles becomes possible. Moreover, since the sliding roof when opened is supported by the roof panel via the slider member and fixed to the rear window by a fixed part, the support rigidity of the sliding roof to the vehicle body when opened is increased. At the same time, the rigidity and strength of the sliding roof itself is increased. As a result, the amount of sliding movement of the sliding roof becomes large, and the opening area of the opening in the roof panel increases with the amount of movement of the sliding roof, which is sufficient to satisfy the feeling of openness required by the occupants. The opening area can be secured.
