Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to an automobile body joining structure, particularly a car body joining structure having a shape that facilitates the movement of a sealer pen holder at the joint between a roof panel and a pillar. It is.

(Prior art) The position where the roof panel and the pillar part connect, for example, in the case of the front pillar part, is shown in FIGS. 3 and 4.
As shown in the figure, a pillar front outer top 2 is located inside the roof panel 1, and a rail roof side outer front 3 or a rail roof drip 4 is placed inside the pillar front outer top 2. A multilayer sheet metal structure is formed in which a pillar front inner upper 5 is arranged inside the roof side outer front 3.

As shown in FIGS. 5 and 6, a pen holder 6 is used at the joint between the rail roof drip 4 and the pillar front outer upper 2 and the joint between the rail roof drip 4 and the roof panel 1. Sealer 7 was applied to prevent water from entering through these joints and to prevent rust.

(Problem to be solved by the invention) A sealer is applied in a multilayer sheet metal structure in order to prevent water from penetrating from the overlapped portion of the sheet metal, thereby preventing the occurrence of rust. In addition, the appearance of an automobile has become an important factor in terms of its quality, and it is necessary to apply the sealer in such a way that the applied sealer cannot be seen from the outside.

Therefore, when sealer is applied in the direction of the arrow in Fig. 3 using the pen holder 6 in the conventional multilayer sheet metal structure, there is a discontinuous part 1a caused by press processing error as shown in Fig. 5 in the sealer application area. In this case, the tip of the pen holder 6 may come out as shown by the arrow in FIG. 3, causing the problem that the sealer 7 is applied to this part and spoils the appearance of the automobile. When the sealer 7 is applied to areas that impair the appearance of the car, it takes a lot of time to remove the sealer 7, which reduces productivity. If the continuous portion 1a exists, the sealer must be applied carefully so as not to damage the appearance of the automobile, which reduces the efficiency of the sealer application process and also reduces productivity.

In addition, requiring high-precision press processing to prevent such discontinuities would require expensive equipment such as press machines, and it would be difficult to adapt to various car models, so multilayer sheet metal structures That's not a good idea.

The present invention provides an automobile body joining structure that has a simple structure, eliminates discontinuity in the sealer application area, facilitates the movement of a sealer pen holder, and improves the efficiency of sealer application work.

(Means for Solving the Problems) The means according to the present invention for solving the above problems is such that a pillar front outer top is located inside a roof panel as a vehicle body member, and the pillar front outer top is located inside the pillar front outer top. In a car body joint structure of a multilayer sheet metal structure, in which a rail roof side outer front or a rail roof drip is arranged on the side, and a pillar front inner upper is arranged on the inside of the rail roof side outer front or the rail roof drip, the car body A flange end inclined in the direction of movement of the pen holder is formed on the roof panel at the overlapping part of the members, and the movement of the pen holder is made substantially continuous at the joint between the end of the roof panel and the end of the pillar front outer top. It is characterized by the fact that

(Function) Since the present invention is constructed in this way, discontinuous parts are eliminated without requiring high-precision press processing, and the sealer can be applied to the roof panel by using the flange end that is inclined in the pen holder movement direction provided on the roof panel. The movement of the pen holder is carried out along a substantially continuous section at the joint between the end of the panel and the end of the pillar front outer upper.

(Example) An example of the present invention will be described below. 1st
As shown in the figures and FIG. 2, a rail roof side outer front 3 and a rail roof drip 4 are arranged inside the pillar front outer upper 2, and the rail roof side outer front 3
A pillar front inner top 5 is arranged inside to form a pillar part, and a roof panel 10 having a flange end 10a is arranged outside a pillar front outer top 2 forming the pillar part. Forms the front pillar (upper) part. The flange end 10a is inclined in the direction of movement of the pen holder 6 when applying the sealer, and is formed by cutting out a part of the roof panel 10 in advance (FIG. 2) when pressing the roof panel 10. . Flange end 1 formed in this way
By arranging the roof panel 10 having 0a on top of the pillar front outer top 2, as shown in FIG. The parts become continuous.

The operation of this embodiment configured in this way will be explained next.Even if there is some machining error in the pillar front outer top 2 and the roof panel 10, the roof panel 10 can be stacked on the pillar front outer top 2. This makes the end 2a of the pillar front outer upper 2 and the end of the roof panel 10 continuous. In FIG. 1, water enters from the joint between the rail roof drip 4 and the pillar front outer upper 2 to the joint between the rail roof drip 4 and the roof panel 10. Therefore, the sealer 7 will be applied to this portion. Therefore, to apply the sealer to this area, first move the pen holder 6 along the end 2a of the front outer top of the pillar while applying the sealer, and when the pen holder 6 moves from the end 2a of the front outer top of the pillar to the roof panel 10. Since the flange end 10a provides a continuous line between the end 2a of the pillar front outer top and the end of the roof panel 10 so that there is no step, the movement of the pen holder 6 is also continuous. are moved in the same direction (direction in Figure 3).
Therefore, when applying the sealer, the pen holder 6 is moved in the same position and the application is performed as if the sealer was being applied to a single board, without taking any special precautions.

As a reference example, as shown in FIG. 7, the moving direction of the pen holder 6 is perpendicular to the paper surface,
In addition, there is also a discontinuous portion in the direction of movement of the pen holder 6 when the sealer application portion moves from one portion of the pillar front outer upper upper 2 to two portions of the pillar front outer upper upper 2 and the roof panel 10. . In such cases, roof panel 1
By cutting out the 0 and forming the flange end 10a, the direction of movement of the pen holder becomes continuous. In addition, as shown in FIG. 8 as a reference example, the pen holder 6
If the direction of movement of is to the right in the drawing, the sealer applied part is
There is also a discontinuity in the direction of movement of the pen holder 6 when moving from one section to two sections, the pillar front outer upper 2 and the roof panel 10. Even in such a case, by cutting off the roof panel 10 and forming the flange end 10a,
The direction of movement of the pen holder 6 becomes continuous.

(Effects of the invention) As detailed above, according to the invention, the roof panel is provided with a flange end inclined in the direction of movement of the pen holder, and the end of the roof panel and the end of the pillar front outer top are connected to each other. Since the ends of the pen holder are substantially continuous, the pen holder can be easily moved. As a result, the sealer is not applied to unnecessary parts, eliminating the need for removal work, and the work can be made more efficient and productivity can be greatly improved without paying special attention to the sealer application work.

In addition, by forming the flange end in advance at the time of press working in this way, the tolerance range for dimensional errors in press work is expanded, making press work easier, and equipment such as press machines It is possible to reduce costs.
