DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the rear gate structure of the present invention will be described below with reference to the drawings. FIG. 1 is a half perspective view of the rear gate structure of the present invention viewed from the inside, FIG. 2 is an overall perspective view of the rear gate structure viewed from the outside, and FIG. 3 is a cross-sectional view taken along the line AA of FIG. FIG. 4 is a sectional view taken along line BB of FIG. 2 with the rear gate glass mounted. The rear gate structure according to the present invention is a rear gate structure which is attached to the rear end opening of the vehicle body so as to be openable and closable. The rear gate panel 1 is formed of an integrally molded product manufactured by die casting.

As shown in FIGS. 1 and 2, the rear gate panel of the present invention is made of a molten and light metal material such as aluminum or magnesium. The light metal molten material is injection-molded in a predetermined mold, and the molded product is formed. After being cooled and solidified, it is manufactured by die casting in which a die is cut in a predetermined direction. The ribs 4 formed on the inner and outer wall surfaces 2 and 3 of the rear gate panel are preferably formed in a shape that is easily die-cut, for example, a simple upright shape, but if the die-cutting is devised. The ribs may be formed in a slightly complicated form. A window opening 6 is provided at a substantially central portion (slightly upward) of the rear gate panel 1.
An upper rear gate panel 1b located above the window opening 6 and side rear gate panels 1a located on both sides;
The lower rear gate panel 1c located at the lower part is provided with a large number of ribs in a grid pattern.

In the illustrated example, the upper rear gate panel 1b
The grid-like ribs 4 are formed on the inner wall surface of the lower rear gate panel 1c and on the outer wall surface of the side rear gate panel 1a, but if the design of the rear gate panel 1 can secure the strength of each panel. The upper, lower and side gate panels 1b, 1b,
at least one panel or 2 of c and 1a
The ribs 4 may be formed only on one panel. Normally, the window opening 6 is set to be almost the width of the vehicle in order to maximize the amount of light entering the cabin. For this reason, the width of the side rear gate panel 1a becomes narrow. In addition, it is necessary to secure a space such as a sealing member 11 for preventing intrusion of water droplets and a trim for absorbing shock and noise on the indoor side, which are indispensable when the rear gate glass 5 is mounted. It is not possible to secure a dimension for forming the ribs 4 enough to maintain the strength inside the panel 1a.

Therefore, in the present embodiment, the side rear gate panel 1a has a rib 4 formed on the outer wall 3 as shown in FIG.
Although not having a sufficient dimension in the width direction, it is possible to secure a sufficient strength by forming as many ribs as possible on the wide outer wall 3 which is less restricted than the inner wall 2. Here, the ribs 4 formed on the outer wall surface 3 are usually configured such that the edges are covered by an opaquely colored rear gate glass 5 and are not exposed to the outside, so that the appearance is not impaired. . The ribs 4 may be formed on the inner wall surface 3 or may be formed on both the inner and outer surfaces as long as the surface area of the inner wall surface 2 can be sufficiently obtained according to the design shape of the side rear gate panel 1a.

As shown in FIG. 3, one of the ribs 4 formed on the inner wall surface of the upper rear gate panel 1b near the upper end thereof.
A gate opening / closing hinge 7 is installed using the rows, and is fixed to a corresponding portion of the vehicle body 8 with a bolt or the like. A row of ribs 4 formed on the inner wall surface of the upper rear gate panel 1b and extending in the vehicle width direction is brought into contact with a corresponding portion of the vehicle body via the sealing member 9 when the rear gate panel 1 is closed. A hit seal is configured. The sealing member 9
Has functions of absorbing shock, preventing noise, and preventing ingress of water droplets. The surface area of the ribs 4 constituting the door stop seal is slightly larger than other ribs, so that a sufficient area for installing the seal member is secured. A rear spoiler 10 for air flow regulation is integrally formed at the rear end of the upper rear gate panel 1b.

As shown in FIG. 3, a lower end of the lower rear gate panel 1c has a latch 1 which can be engaged with a striker (not shown) installed on the vehicle body 8 below the gate opening.
2 are provided. A joining flange 13 is formed on the outer peripheral edge of the window opening 6 of the rear gate panel 1.
The rear gate glass 5 is joined to the joining flange 13 by bonding or the like. At that time, both sides of the rear gate glass 5 are mounted so as to cover the side rear gate panel 1a in which the ribs 4 are formed on the outer wall surface 3. Further, water and the like do not enter the peripheral edge of the rear gate glass 5 from a gap between the rear gate glass 5 and the joining flange 13.
The mall 14 is attached as a decoration.

The embodiments of the present invention have been described above. However, within the scope of the present invention, the shape of the rear gate panel including the shape of the upper and lower and side panels, the shape of the ribs, the die casting method, the door Relative structure of the ribs that make up the hit seal and the vehicle body side members (if the design is acceptable, the door hit seal is not only placed on the upper rear gate panel, but also on the inner wall surface that extends from the upper side to the side and lower rear gate panels. It may be formed by using ribs formed continuously in a shape), the shape of the rear spoiler, the shape of the window opening, the mounting form of the rear gate glass in the window opening, the shape of the hinge, etc. Can be appropriately selected.

[0013]

As described above in detail, according to the present invention, in the rear gate structure which is attached to the rear end opening of the vehicle body so as to be openable and closable, the inner wall surface exposed to the inside of the vehicle body and the outer wall to the outside of the vehicle body are exposed. By combining the rear gate panel consisting of the outer wall surface and the ribs that reinforce them with an integrally molded product manufactured by die-casting, spot joining of multiple members with pre-processes such as pressing as in the conventional case This eliminates the necessity of assembling work, etc., simplifies the production process, improves the working efficiency and lowers the cost, and improves the degree of freedom of molding limited by press forming.

Also, an upper rear gate panel located above a window opening provided at a substantially central portion of the rear gate panel, a side rear gate panel located on both sides, and a lower rear gate panel located on a lower side. At least one
When ribs are formed on one panel, the strength of the rear gate can be easily ensured by integrally forming the ribs as required. Further, when ribs are formed on the inner wall surfaces of the upper rear gate panel and the lower rear gate panel and the outer wall surfaces of the side rear gate panels, the strength of the entire rear gate can be reliably improved.

Further, when at least one of the ribs formed on the rear gate panel is configured to contact the vehicle body via a sealing member when the rear gate is closed, the rib is used as a sealing surface. Water droplet intrusion prevention,
Since shock absorption and noise prevention can be achieved, it is not necessary to form a ridge or the like that particularly forms a sealing surface. When the rear spoiler is integrally formed with the rear gate panel, the installation of a smooth streamlined rear spoiler with low fluid resistance is extremely easy. As described above, according to the present invention, a rear gate structure is provided in which the number of parts is reduced and the cost is reduced, and the productivity and the degree of freedom of design are improved by adopting a simple structure.
