Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a connection structure between a rear fender and a rear panel that constitute the rear body of an automobile.

(Prior art) Conventionally, in the case of a connection structure between a rear fender and a rear panel that constitute the rear body of an automobile, the first
As shown in Figures 1 and 2, in order to improve the efficiency of assembly line work, a pair of left and right rear fenders 2 are arranged in parallel with a predetermined interval, and the width is approximately equal to the interval between the rear fenders 2. After the rear panel 3 is superimposed on the rear fender 2 from the outside and the two are spot welded, a sealing material 8 such as a weather strip is finally applied on the joining line to complete the connection work.

However, in the configuration of such a conventional example,
At the overlapping joint between the rear fender 2 and the rear panel 3, the edges 6a and 6b of the rear panel upper 6 are located outside the edges 2a and 2b of the rear fender, making it difficult to repair the rear body or deterioration of the sealant over time. For reasons such as this, rainwater flowing in the drip channel 21 on the side of the rear fender 2 may cause damage to the inner gap of the rear panel upper 6 of the rear panel 3, that is, the joint between the rear fender 2 and the rear panel upper 6. Through the gaps formed in the parts, the fuel remains in the trunk room 4, causing internal corrosion.

As a countermeasure against this, the edge 2a of the rear fender,
2b is overlapped and joined to the outside of the edges 6a and 6b of the rear panel upper to guide rainwater, etc. flowing on the rear fender 2, especially inside the drip channel 21 of the rear fender, to the outside of the rear panel 3, that is, to the side opposite to the trunk room. A method to do so has been proposed. However, according to this method, it is necessary to insert the edges 6a, 6b of the rear panel upper inside the edges 2a, 2b of the rear fender. Install the upper 6 on the rear panel in advance.
The rear panel upper 6 is attached to the lower 7 and the floor 5, and is tilted toward the trunk room 4 within the elastic limit as shown by the chain line in FIG. 3, and then the rear fender 2 is raised from the side. Edges 6a and 6b of the rear panel top
It was overlapped and joined on top.

According to the configuration of the conventional example, the edges 2a and 2b of the rear fender are located outside the edges 6a and 6b of the rear panel upper, that is, on the side opposite to the trunk room, and function as a roof, so that the rear fender drips. Rainwater or the like flowing within the channel 21 is directly drained to the outside of the rear panel upper 6, and as a result, the problem of intrusion into the trunk room 4 is completely solved. However, in this conventional example, the rear panel upper 6 of the rear panel 3 is inclined toward the trunk room 4 within its elastic limit, and the edges 6a, 6b of the rear panel upper are connected to the rear panel lower. On the edge 7a, the edges 2a and 2b of the rear fender
The installation procedure involves overlapping and joining the rear fender edges 2a and 2b, which have a flat plate-like cross-sectional shape, and the rear panel upper, which has a dogleg-shaped cross-sectional shape. Since it is difficult to align the end faces with the edges 6a and 6b, the efficiency of assembly line work is low and this is also a factor in high costs. In addition, as a reference, Utsukai 52-
No. 80913 is mentioned.

(Objective of the Invention) Therefore, the present invention is intended to solve the above-mentioned problems of the prior art, and its purpose is to drain rainwater flowing on the rear fender to the outside of the rear panel and into the trunk room. To prevent intrusion and to easily and quickly join a rear fender and a rear panel together, thereby improving the efficiency of assembly work and reducing costs.

(Structure of the Invention) In order to achieve the above object, the rear body connection structure for an automobile according to the present invention provides a rear body connection formed by overlapping and joining the edge of a rear fender and the edge of a rear panel. It is a structure,
A protrusion protruding toward the center of the vehicle is formed on the lower side of the rear fender, and a protrusion is recessed toward the center of the vehicle in correspondence with the protrusion of the rear fender near the mounting base of a rear panel upper constituting the rear panel. The vehicle is characterized in that a notch is formed, and a guide piece is provided in the notch to project in a curved manner into the trunk room.

Further, in the rear body connection method of an automobile according to the present invention, there is provided a rear body connection method in which an edge of a rear fender and an edge of a rear panel are overlapped and joined, and the lower part of the rear fender is connected to the center of the vehicle. A protrusion protruding to the side is formed, and a notch is formed near the mounting base of the rear panel upper constituting the rear panel to correspond to the protrusion of the rear fender and is recessed toward the center of the vehicle. A guide piece is provided that protrudes into the trunk in a curved manner, while the rear panel upper is connected to the floor for positioning and fixing, and the rear fender is connected to the rear panel with a rotation shaft positioned below the rear fender. It is characterized in that the rear panel upper and the rear fender are gradually overlapped from the protrusion side by raising the rear panel at the center.

(Embodiment) The present invention will be explained below based on the illustrated embodiment. In FIGS. 3 and 4, reference numeral 1 denotes a rear body constituting the rear part of the vehicle body, and this rear body 1 is generally attached to the side surface of the vehicle body. A rear fender 2 is located, a rear panel 3 is located at the rear of the vehicle body and is interposed between both rear fenders 2, 2, and a trunk room 4 is formed above by being arranged inside both rear fenders 2, 2 and rear panel 3. The rear panel 3 includes a rear panel upper 6 and a rear panel lower 7. More specifically, 20 is a flange that extends from above the rear fender toward the trunk room 4 and is integrally provided with a drip channel 21. Reference numeral 60 denotes a through hole for a pair of combination lamps provided in the rear panel upper part 6, and 61 denotes a mounting base formed over the entire length of the lower end of the rear panel upper part 6, which is the connection part with the floor 5 and rear panel lower 7. , the mounting base 61
A substantially rectangular guide piece 62 is provided at both left and right ends of the rear panel upper 6, and this guide piece 62 protrudes in a curved manner toward the trunk room 4 side. The lower part of the rear fender 2 is provided with a protrusion 22 that protrudes toward the center of the vehicle, while the rear panel upper 6 has a cutout that is recessed toward the center of the vehicle in correspondence with the protrusion 22. 63 is formed. The guide piece 62 is provided in this notch 63.

To explain the installation procedure for the rear body constructed as described above, the rear panel upper 6 connected to the floor 5 and the rear panel lower 7 at the mounting base 61 is moved to its normal position within its elastic limit. 61 as a reference and set it so that it is tilted toward the front of the vehicle (see the chain line in FIG. 3). Next, the rear fender 2 rotates around the rotation axis located below it, rises from both sides of the vehicle, and is set in its normal position, but in this case, as shown in FIG. ,
The part where the rising edge 2b of the rear fender and the lower edge 6b of the rear panel upper most likely interfere, that is, the mounting base 6 of the rear panel upper.
1, there is a guide piece 62 that guides the edges 2a, 2b of the rear fender to the outside of the rear panel upper 6. The drip channel end edge 2a and the rising end edge 2b can be easily and quickly overlapped. Note that since the upper end 62a of the guide piece 62 is formed in a curved shape, the rising edge 2b of the rear fender can be smoothly guided to the normal overlapping position without being caught by the guide piece 62.

Further, since the protruding part 63 of the rear fender 2 guided by the guide piece 62 partially protrudes, it is easily bent in the bending direction, and the deflection of the protruding part 63 causes the rear fender 2 to
The contact pressure between the joint surfaces of the rear fender 2 and the rear panel upper 6 is reduced, and the edges of the rear fender 2 and the rear panel upper 6 can be smoothly overlapped with each other without resistance. Since the guide piece 62 is integrally molded using the material of the portion to be cut out as the notch 63, the material can be used effectively. Although the protrusion 62 is provided on the side of the rear fender 2, the rear fender 2 is usually formed by deep drawing and then trimming the edge 2b into the required shape, so the shape may change slightly. However, the material yield is not affected at all.

In this way, after the rear fender 2 is superimposed on the outside of the rear panel 3, the rear panel upper 6 is pulled rearward and set in its proper position, and then the two are connected by spot welding or the like to complete the assembly work. . In the state after installation is completed, the upper edge 6a and lower edge 6b of the rear panel
The drip channel edge 2a and the rising edge 2b of the rear fender are overlapped and joined from the outside, and the rear fender 2 functions like the roof of a house, so in the unlikely event that the sealing material 8 Even if an unexpected situation occurs in which the sealing function deteriorates, all the rainwater flowing on the rear fender 2 will be drained to the outside of the rear panel 3, that is, to the side opposite to the trunk room, and therefore no rainwater will enter into the trunk room 4. do not have.

(Effect of the invention) The present invention consists of the above structure and operation,
Rainwater flowing on the rear fender can be drained to the outside of the rear panel to prevent it from entering the trunk room, and the rear fender and rear panel can be joined together easily and quickly, improving assembly efficiency and reducing costs. It has the effect of reducing Furthermore, since the guide piece is provided near the mounting base of the rear panel upper where the rear fender and rear panel tend to interfere, the work of overlapping the rear fender and rear panel can be performed more easily and quickly.

Furthermore, since the protrusion on the lower side of the rear fender is guided by the guide piece, the protrusion easily bends in the bending direction. The contact surface pressure acting between the rear fender and the rear panel can be reduced by the bending of the protrusion in the bending direction, and the work of assembling the rear fender and the rear panel can be further facilitated.

Further, since the guide piece is provided in the notch of the rear panel upper, the cutting of the material of the rear panel upper is not deteriorated at all, and the material can be used effectively.

Furthermore, according to the second aspect of the present invention, the rear fender is guided by the guide piece and gradually stacked on the rear panel from the lower side thereof, so that the assembly work can be performed more smoothly.
