Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a rear door structure for a vehicle.

(Prior Art) In general, an automobile door has a door panel main body pivoted to a pillar on the vehicle body side via a hinge mechanism so that it can be opened and closed freely, and a door trim (trim board) for interior use is attached to the side surface of the vehicle interior of the door panel.
It is configured by arranging.

Among the above-mentioned automobiles, in particular, in a four-door or five-door type vehicle having a pair of front and rear front and rear doors on both sides of the vehicle body, the front end of the front door is connected to the front pillar of the vehicle body, and the front end of the rear door is connected to the front pillar of the vehicle body. are pivotally connected to the vehicle body side center pillar via hinge mechanisms, so that the fitting edges of the two doors are located in front and behind the center pillar with the center pillar in between. As a result, the metal panel surface of the center pillar is exposed inside the vehicle. For this purpose, an interior trim member has conventionally been attached to the surface of the center pillar exposed to the interior side of the vehicle, similarly to the inner surface of the door (see, for example, Japanese Utility Model Application No. 59-64350).

(Problem to be solved by the invention) However, with the above configuration, the center pillar itself exists (exposed), and two door fitting edges exist in the vertical direction before and after the center pillar. Since there is no difference in any way, it is impossible to have a clean appearance. Furthermore, since a trim member dedicated to the center pillar must be prepared separately from the door trim, there are problems such as an increase in the number of parts and an increase in the number of assembly steps.

(Means for Solving the Problems) The present invention was made with the aim of solving the above problems, and is a rear door panel whose front end is pivotally connected to a center pillar in the center of the side of the vehicle body via a hinge mechanism. In the rear door of a vehicle, the front end of the rear door trim is extended to the vicinity of the front end of the center pillar; The rear door panel is fixed to the rear door panel through a reinforcing member.

(Function) According to the above means, first, the front end of the rear door trim extends to the vicinity of the front end of the center pillar, so the fitting line of the front and rear doors becomes approximately one in the vertical direction, which improves the appearance. Not only does the design improve the appearance, but it also eliminates the need to attach a special trim member to the center pillar itself, reducing the number of parts and assembly man-hours.

Further, since the extending portion of the rear door trim is fixed to the rear door panel body via the reinforcing member, its supporting rigidity is sufficiently high.

(Embodiment) FIGS. 1 to 3 show a rear door structure for a vehicle according to a first embodiment of the present invention.

First, FIG. 2 shows a schematic configuration of a rear quarter section of a four-door type automobile body A, for example, and reference numeral 1 denotes a roof located on both sides of the automobile body A and extending in the front-rear direction. This is the side rail part. A front door 7 and a rear door 15 are provided below the roof side rail portion 1, with the center pillar 11 in between. As shown in FIG. 1, the center pillar 11 is formed by joining a center pillar outer panel 12 and a center pillar inner panel 13 to each other so as to form a predetermined closed cross section inside them, and the center pillar 11 is formed by joining a center pillar outer panel 12 and a center pillar inner panel 13 to each other so as to form a predetermined closed cross section on the inside thereof. Moldings 14 and 15 are provided at both ends, respectively.
is fitted.

The rear door 15 includes a door panel portion 8 and a rear door glass portion 2, and a rear door trim member 30 is attached to a side surface of the door panel portion 8 in the vehicle interior. Moreover, the trim member 3
An armrest 5 for the rear seat 6 is attached to the center of the side surface of the vehicle interior.

On the other hand, the center pillar 11 is supported in an upright state on vehicle side sills 4 located on both sides of the vehicle floor panel 3 and extending in the longitudinal direction of the vehicle body.

By the way, the door panel portion 8 of the rear door 15 is made up of a rear door outer panel 16 and a rear door inner panel 17, as shown in detail in FIG. The portion 18 side is integrally joined to both ends of the rear door outer panel 16. Above rear door inner panel 1
A hinge pin support bracket 20 having a U-shaped cross section is fixed to the front end 19 of the frame 7 via a bolt member 21, while an angular hinge arm 24 is fixed to the corresponding center pillar 11 side. Both are pivotally connected to each other via a hinge pin 23 supported by the hinge pin support bracket 20, thereby supporting the door panel portion 8 so as to be rotatable in the horizontal direction with respect to the center pillar 11. has been done.

On the other hand, the rear door trim member 30 is made by delivering a synthetic resin core material 32 inside a relatively rigid hollow trim board outer body 31, and its front end 38 is the front end of the center pillar 11. The reinforcing member 3 is extended to the inner side of the extended portion 30A.
3 to the rear door inner panel 17.

The reinforcing member 33 has a front end arranged along the inside of the extension part 30A of the trim member 30, and is attached to the trim board outer body 31 by a first rivet 36 and a rear end to a second rivet. 37 at a right angle to the rear door inner panel 17 side near the connection part with the trim board outer body 31,
A first reinforcing panel 35 is formed by molding a sealing rubber member 45 on the bent piece 34, and one end thereof is bent into a substantially triangular shape in the middle of the fastening portion of the first reinforcing panel 35 to the trim member 30. The raised joint 39 is connected and fixed by a screw member 40, while the other end overlapping part 42 with the rear door inner panel 17 is fastened and fixed to the rear door inner panel 17 by a bolt nut member 43. The second reinforcing panel 41 is made up of:

Therefore, the extending portion 30 of the trim member 30
The reinforcing member 33 fastened and fixed to the inside of the trim member 30 reinforces the entire extended portion 30A of the trim member 30 and improves its rigidity, and furthermore, the second reinforcing panel 41 is connected to the first reinforcing panel 35 through the first reinforcing panel 35. Thus, the trim member 30 itself is firmly fixed to the door panel portion 8. As a result, the strength of the extending portion 30A of the rear door trim member 30 becomes sufficiently high. In FIG. 2, the reference numeral 9 is a kick panel portion of the rear door 15, and in FIG. 1, the reference numeral 25 is a weather strip having a damper function.

According to the above configuration, as shown in FIG. 3, the extending portion 30A of the trim member 30 provided on the rear door 15 almost completely covers the center pillar 11, so that the fitting of the door appearing inside the vehicle interior is prevented. The joining edge is only one line L formed in the vertical direction by the rear end of the front door 7 and the front end of the trim member of the rear door 15. Therefore, the appearance of the side wall of the vehicle compartment becomes sleeker, and the appearance is further improved.

Moreover, the trim member extension portion 30 of the rear door
Since A is firmly reinforced and fixed to the door panel 8 by the reinforcing member 33, its support rigidity is also sufficient.

Next, FIG. 4 shows a rear door structure for a vehicle according to a second embodiment of the present invention, in which the reinforcing member of the trim extension portion of the rear door 15 is constructed of a single reinforcing panel. .

That is, the reference numeral 30 indicates the same rear door trim member as that of the first embodiment, and its front end 38 extends to the front end of the center pillar 11 as described above. And the extension part 30A
A reinforcing member 60 having a substantially T-shaped cross section is provided inside. This reinforcing member 60 has one end side bent part 62b joined to the back surface of the trim member 30, and the other end side bent part 62a is fastened to the rear door inner panel 17 via a connecting pin 65, so that the trim member 30 is connected to the above mentioned trim member 30. A trim member attachment piece 62 to be attached to the door panel 8 of the rear door 15 extends from a substantially central position of the trim member attachment piece 62 to the back side of the front end 38 of the trim member 30 and is joined to the trim member attachment piece 62 . The trim member attachment piece 62 has a rubber member 45 for sealing molded on the front side of the trim member attachment piece 62.

Even with such a configuration, the extending portion 30A of the trim member 30 that covers the center pillar 11 can be sufficiently reinforced and supported, and in particular, since the reinforcing member 60 is formed in one piece, its structure and assembly can be improved. Both have the advantage of being simple.

As explained above, the present invention includes a rear door panel whose front end is pivotally connected to the center pillar at the center of the side of the vehicle body via a hinge mechanism, and a rear door trim for interior use is attached to the side surface of the vehicle interior of the rear door panel. The rear door of the vehicle is characterized in that the front end of the rear door trim extends to the vicinity of the front end of the center pillar, and the extended part is fixed to the rear door panel via a reinforcing member. That is.

Therefore, according to the present invention, first, the front end of the rear door trim extends to the vicinity of the front end of the center pillar, so the fitting line for the front and rear doors becomes approximately one in the vertical direction, which improves the appearance. In addition to improving the appearance, there is no need to attach a special trim member to the center pillar itself, and the number of parts and assembly man-hours can be reduced.

Further, since the extending portion of the rear door trim is fixed to the rear door panel body via the reinforcing member, its supporting rigidity is sufficiently high.
