The present invention relates to the rear body structure of an automobile.

First, to explain the conventional rear body structure of this type, in FIG. 1, A is a rear lamp attached to the rear body, 31 is a rear panel, and 32 is a bracket integrally formed on the left end of the rear panel. consists of a bottom plate 33, a ceiling plate 34, and a side plate 35, and has a space 36 that opens toward the left and rear and into which the rear lamp A can be fitted. At the back of the void is a flange 37.
In addition, flanges 38 are protruded or formed in front of the respective flanges 38 . An end plate 39 forming the upper end surface of the rear panel 31 is formed integrally with the rear panel, is connected to the ceiling plate 34 via a flange 40, and is provided above and parallel to the ceiling plate. 41
is a flange projecting from the edge of the end plate 39. Next, reference numeral 42 denotes an expansion panel formed by bending a plate-like body into a character shape. ing. Reference numeral 46 denotes a flange protruding from the expansion panel. Next, 47 is a quarter panel on the left side of the rear vehicle body, 48 is an opening formed at the rear end of the quarter panel, and the opening is formed by an edge 49 and a flange 50 formed by bending the edge of the opening. Compartment, formed. Next, 51 is a rear corner formed by bending a plate-like body at right angles, and this rear corner is formed by a vertical plate 52 extending in the front-rear direction.
The horizontal plate 53 extends in the front-rear direction and has a rear end bent in an L-shape. 54 and 55 are flanges projecting from the vertical plate 52 and the horizontal plate 53, respectively.

Next, the rear panel 31, the expansion panel 42, the quarter panel 47, and the rear corner 51 are connecting members that constitute the left side of the rear vehicle body.
To connect the expansion panels 42 to each other, first move the expansion panel 42 to the left side of the quarter panel 47 while keeping it in the same position, and then push the expansion panel to the right to connect the quarter panel 47.
When inserted into the opening 48 of the flange 46, the flange 46 comes into contact with the flange 50, so that the quarter panel 47 and the expansion panel 42 can be joined by spot welding these two flanges. In order to next connect the expansion panel 42, which has been connected to the quarter panel 47 inside the opening 48 of the quarter panel 47, to the left end of the rear panel 31, the rear panel must be held in the same position and moved to the left. When the bracket 32 is moved, the expansion panel 42 connected to the quarter panel 47 as described above is inserted into the space 36 of the bracket 32, and the flange 46 of the expansion panel is attached to the flanges 38, 40 on the rear panel side. At the same time, the flange 37 of the bracket 32 comes into contact with the outer surface (back surface) of the connecting plate 45, so by spot welding the abutting flanges, connecting plates, etc., the expansion panel 42 is joined to the left end of the bracket 32. Consequently, a quarter panel 47 having an opening 48
is connected to the left end of the rear panel 31 via an expansion panel 42, and a space 36 is provided in the left side of the rear vehicle body into which the rear lamp A can be inserted and mounted. In this case, the outer surfaces of the bottom plate 43 and ceiling plate 44 of the expansion panel 42 are similar to the bottom plate 33 and ceiling plate 3 of the bracket 32.
4, and the left end of the end plate 39 of the rear panel 31 is overlapped with the ceiling plate 44 of the expansion panel 42 at a distance within the opening 48 of the quarter panel 47. Further, the end plate or rear panel 31 is substantially perpendicular to the quarter panel 47 at its rear end. Next, the rear corner 51 is attached to the corner formed between the quarter panel 47 and the rear panel 31 which intersect with each other as described above, and the rear end of the quarter panel 47 and the rear panel 31 are attached at the corner. This is a connecting member that connects the left end portions, and in order to install the rear corner as described above, first move the rear corner to the left as shown in the illustration, and as it approaches the quarter panel 47, move it downward. By pressing down, the L-shaped rear end of the horizontal plate 53 is overlapped and bonded to the left end of the end plate 39 of the rear panel 31, and then the flange 54 of the vertical plate 52 is attached to the quarter panel. At the same time, the flange 55 of the horizontal plate 53 is welded to the flange 41 of the end plate 39. In this way, the left end portion of the rear panel 31 is connected to the quarter panel 47 via the rear corner 51 at the corner portion. In the drawings, reference numeral 57 indicates a door holder attached to the opening edge 56 of the quarter panel 47. Furthermore, although only the left side of the rear vehicle body has been described above, there is no need to explain the right side, which has the same structure as above, and will therefore be omitted.

The conventional rear vehicle body having the above structure has the following problems. In other words, the rear panel, which is formed by integrally forming a bracket with a space at both ends into which the rear lamp is fitted, and the expansion panel, which is formed by bending and forming a plate-like body into an L-shape, are each deep-drawn. When joining, the accuracy of face-to-face alignment between each other and the rear corners is poor, and the joining and sealing properties are poor. In particular, the processability of deep drawing on large items such as the rear panel is extremely poor.

The present invention was proposed to eliminate the above-mentioned problems, and its gist is that the rear panel and quarter panel, which form the outer surface of the vehicle body, have an integrally formed space into which a rear lamp can be fitted. The peripheral edge of the outer end of the panel in the vehicle width direction is connected to the opening peripheral edge formed across the rear end surface and the outer surface of the quarter panel, and the upper end is located inside and above the outer end of the expansion panel in the vehicle width direction. A rear corner is formed which extends further forward of the vehicle body and is integral with the expansion panel, an outer end of the rear corner in the vehicle width direction is connected to an upper inner end of the quarter panel, and a rear corner is formed that extends further forward of the vehicle body and is integral with the expansion panel. an extension part that connects the inner end in the vehicle width direction to the outer end vertical wall in the vehicle width direction of the rear panel, and extends outward in the vehicle width direction from the outer end vertical wall to connect the lower end of the rear panel and the lower end of the quarter panel; The bottom end of the expansion panel is joined to the bottom end of the expansion panel. In this way, according to the present invention, it is possible to eliminate all of the above-mentioned problems of the conventional structure, and also to reduce the number of connected parts and the accompanying cost reduction.

Next, the present invention will be explained in more detail with reference to the embodiment shown in the drawings. In FIG. 2, 1 is a rear panel, 2 is a notch formed by cutting out the upper left end of the rear panel, and 3 is the notch. 4 is an end plate forming the upper end surface of the rear panel 1, and 4' is a flange protruding from the end plate. Next, 5 is an expansion panel, which includes a bottom plate 6,
A space 10 consisting of a ceiling plate 7, a connecting plate 8 and a side plate 9, which opens toward the left and rear, into which a rear lamp A shown in FIG. 1 can be fitted.
It is equipped with Reference numeral 11 designates a series of flanges formed by bending the edges of the opening of the cavity to surround the opening. Next, reference numeral 12 denotes a rear corner having the same structure as the rear corner 51 shown in FIG. In the case of the present invention, the rear corner is formed integrally with the expansion panel 5,
The L-shaped rear end of the horizontal plate 14 is connected to the right end of the ceiling plate 7 via the flange 11, and
They are folded at a distance above the right end. Next, 17 is a quarter panel on the left side of the rear vehicle body, 18 is an opening formed at the rear end of the quarter panel, 19 is a vertical flange formed by bending the edge of the opening, and 20 is similarly formed. The upper flange is formed. Reference numeral 21 designates a door holder welded to the opening edge 22 of the quarter panel 17.

Next, the rear panel 1, expansion panel 5, and rear corner 1 that constitute the left side of the rear vehicle body
2 and the quarter panel 17, first move the expansion panel 5 together with the rear corner 12 to the left and insert the left end of the expansion panel into the opening 18 of the quarter panel. By circumscribing the longitudinal flange 19 and the upper flange 20 of the quarter panel to the flange 11 at the left end of the expansion panel 5 and welding these abutting flanges together, a quarter panel 17 having an opening 18 is formed. Expansion panel 5 having a void 10 at the rear end
are connected, and at that time, the rear corner 12 moves in the same way as the expansion panel that moved to the left as described above, and the flange 1 of the rear corner 12
Since the flange 5 is close to the opening edge 22 of the quarter panel, the flange can be welded near the opening edge. Therefore, by welding the flange near the opening edge, the rear corner 12 is attached to the corner formed between the quarter panel 17 and the expansion panel 5, which intersect with each other, and the rear corner 12 is attached to the corner formed between the quarter panel 17 and the expansion panel 5, which intersect with each other. is connected to the quarter panel 17. Next, in order to connect the left end of the rear panel 1 to the expansion panel 5 that has been connected to the quarter panel 17 as described above, move the rear panel to the left in the orientation shown in the figure, and tighten the flange 3 of the rear panel. The flange 4' of the end plate 4 of the rear panel may be welded to the rear end of the flange 16 of the rear corner 12 at the same time as the flange 11 at the right end of the expansion panel. In this way, the rear panel 1, expansion panel 5, rear corner 12 and quarter panel 17
By connecting them together, the left side of the rear vehicle body is constructed, and a space 10 can be provided in which the rear lamp A can be fitted. Although only the structure of the left side of the rear vehicle body has been described above, the structure of the right side is also omitted because it has the same structure as above.

As shown in the above embodiment, the structure of the present invention is as follows:
In a rear panel and a quarter panel that form the outer surface of the vehicle body, a peripheral edge of an outer end in the vehicle width direction of an expansion panel that integrally forms a void into which a rear lamp can be fitted is extended between the rear end surface and the outer surface of the quarter panel. A rear corner is formed which is connected to the peripheral edge of the opening formed, extends inward in the vehicle width direction from the outer end of the expansion panel and toward the front of the vehicle body from the upper end, and is integral with the expansion panel, The outer end in the width direction is joined to the upper inner end of the quarter panel, and the inner end in the width direction of the expansion panel is joined to the outer end vertical wall part of the rear panel in the width direction, and the outer end It is characterized in that the lower end of the expansion panel is connected to an extension that extends outward in the vehicle width direction from the vertical wall and connects the lower end of the rear panel and the lower end of the quarter panel.
According to this, the following effects can be obtained.

That is, according to the present invention, the space for inserting and fitting the rear lamp, which was conventionally formed in the rear panel, is formed in the expansion panel, and the rear corner, which was conventionally formed as a separate joining member, can be formed in the expansion panel. Since it is molded integrally with the panel, there is only one joining member in the deep-drawn shape that is difficult to process, and the two joining members of the rear panel and the expansion panel are each in the deep-drawn shape, so they are connected. It is possible to eliminate all the problems of conventional structures such as poor surface alignment accuracy between connecting members, poor bonding and sealing properties, and extremely poor workability, as well as reducing the number of connected parts and accompanying This is extremely advantageous as it can also reduce costs.
