Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in the rear window structure of an automobile.

[Conventional technology]

Conventionally, as shown in ``Automotive Engineering Complete Book 13 Passenger Car Body'' published by Sankaido, the rear window of a car has been fixed to the car body with a weather strip or the like.

[Problems with conventional technology]

By the way, with such a conventional rear window structure of a car, the rear window cannot be opened or closed, so it is not possible to give the occupants a sufficient sense of openness, and the interior of the vehicle cannot be ventilated immediately. I couldn't.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a rear window structure for an automobile that can ensure a sufficient sense of openness for the occupants and can quickly ventilate the interior of the vehicle.

[Technical means and effects of the present invention]

In order to solve such technical problems, the present invention provides a rear window structure for an automobile that includes a rear window panel 13 formed in a rear window opening so as to be able to come into contact with and separate from the outside of the vehicle body, and Guide rails 6 are formed along the side edge shape of the rear window opening on the inside of the vehicle interior of both the left and right rear quarter portions 5 forming the side edges.
A plurality of guide rails 6 are arranged in parallel in the vertical direction, and one end is connected to the guide rail 6 so as to be slidable and rotatable in the vertical direction, and the other end is connected to the side end of the rear window panel 13. The arms 14 and 15 are connected to each other via a universal joint 27 that is rotatable in the vertical direction and the width direction of the vehicle body, and the arms 1
A wire 2 connected to the ends of the guide rails 4 and 15 on the guide rail side and disposed within the guide rail 6.
0 and a motor 32 that moves the arms 14 and 15 up and down by winding up and lowering the wire 20.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

In the rear window structure of an automobile according to the present embodiment, as shown in FIGS. 1 and 2, guide rails 6 are provided on the interior side of rear pillars 5 as rear quadrants of an automobile 4. , is provided between the upper end 11 and the lower end 12 of the rear pillar 5. That is, as shown in FIG. 2, the rear pillar 5 is formed with a closed section structure by a rear pillar outer panel 7 and a rear pillar inner panel 8, and the guide rail 6 is fixed to the rear pillar inner panel 8 via bolts 9 and nuts 10. has been done.

In this embodiment, as shown in FIG. 3, there are two first arms 14 and two second arms 15 at each end of the rear window panel 13, for a total of four arms. The arm supports the rear window panel 13. and,
The first arm 14 is connected to the rear window panel 13
It is pivoted at approximately the middle position in the width direction, and
The second arm 15 is connected to the rear window panel 13.
It is pivoted near the upper end. These, the first arm and the second arm 14, 15
, one end thereof moves while being guided by the guide rail 6, and the other end is pivoted at both ends of the rear window panel 13 so as to be expandable in the width direction of the vehicle body. That is, as shown in FIG. 2, one end 17 of the second arm 15 is joined to a wire 20 disposed within the guide rail 6. As shown in FIG. The other end 21 of the second arm 15 is rotatably attached to both ends of the rear window panel 13 via a bracket 23 on a shaft 24.

That is, in this embodiment, the second arm 15
A ball stud 22 is formed at the other end 21, and a ball socket 26 is formed at the end of the shaft 24 to rotatably fit into the ball stud 22. The ball socket 26 constitutes a ball joint portion 27. Therefore, the second arm 15 is formed to rotate not only in the perpendicular direction with respect to the shaft 24 but also in the width direction of the vehicle body. Further, as shown in FIG. 4, the guide rail 6 is curved so as to bulge in the vehicle width direction.

Further, the first arm 14 is also attached to the guide rail 6 and the rear window panel 13 with the same configuration as the second arm 15 described above.

Therefore, in this embodiment, when opening the rear window panel 13, first, as shown in FIG. 3, the rear window panel 13 is opened manually.
The rear window panel 13 is supported substantially horizontally by flipping up the lower end of the rear window panel 13 outward, and with the first arm 14 and the second arm 15 extended. after that,
The motor 32 is driven to unwind the wire 20. In this case, since the first arm 14 and the second arm 15 are joined to the wire 20,
These arms 14 and 15 move in parallel and slide downward on the guide rail 6 while supporting the rear window panel 13.
3 on the rear deck 33.
In this case, as shown in FIG. 6, if a straight guide rail 36 is used, two arms 34, 35
moves from the upper end to the lower end of the guide rail 36 while expanding around the two ball joints 27 and 37 as base points. Therefore, the arms 34,3
5, the angle formed by the guide rail 36 gradually shifts from a degree to b degree in the process from the upper end to the lower end of the guide rail 36. As shown in Fig. 5, since the guide rail 6 is curved so as to bulge outward in the vehicle width direction, the angle between the arms 14, 15 and the guide rail 6 can be kept at a constant a degree. As in the case of using the guide rail 36, the ball joint part is
This makes it possible to sufficiently absorb displacement in the outward direction of the vehicle body even without providing the two parts 27 and 37. Therefore, in the automobile rear window structure according to this embodiment, there is no need to provide ball joints at both ends of the arms 14 and 15 that support the rear window panel 13, and manufacturing costs can be reduced. At the same time, it becomes possible to improve the strength of the arms 14 and 15.

In addition, when closing the rear window panel 13, the motor 32 is first driven to move the upper end of the guide rail 6 while the rear window panel 13 is horizontally supported by the first arm and the second arm 14, 15. Move parallel to . Thereafter, the rear window panel 13 is reversed downward to close the rear window panel opening.

In this embodiment, the case where the rear window structure of a vehicle according to the present invention is applied to a hatchback type vehicle has been explained as an example, but the present invention is not limited to this embodiment in any way, and the structure can be applied to a hatchback type vehicle. May be applied. Furthermore, the rotation of the rear window panel 13 from the fully closed position to the substantially horizontal position may not be done manually, but may be done automatically using an arbitrary structure.

〔Effect of the invention〕

Since the present invention is configured as described above, it is possible to manually open and close the rear window panel 13 and to completely open the rear window opening with a simple structure, and furthermore, the rear window panel 13 can be horizontally moved electrically. By being able to lower the vehicle in this state, it is possible to obtain a sufficient sense of freedom and to quickly ventilate the interior of the vehicle.
