Utility Model Registration No. 2587002

However, the conventional outer panel superstructure shown in FIGS. 5 and 6 has the following problems to be solved.
That is, in the prior art of FIG. 5 and FIG. 6, during electrodeposition coating, the electrodeposition paint 20 stagnates into the mating portion 21 between the upper outer surface of the side body outer panel 5a and the inner surface of the drip rail by capillary action. As shown by the arrows in FIG. 6, the electrodeposition paint 20 expanded in the drying process after painting is likely to be ejected to the design surface 5c side of the side body outer panel 5a to contaminate the design surface 5c. The quality of the surface was reduced.

Moreover, in the prior art of the above-mentioned Patent Document 1, it is possible to avoid the coating liquid from flowing out to the design surface of the side body outer panel, but the coating liquid from the upper side of the side body outer panel is directed toward the inner flange. Therefore, it is necessary to machine a notch that is inclined toward the inner flange, and requires a special machining process such as cutting or cutting to form the notch. As a result, the processing cost of the entire outer panel increases.
In the case of such a technique, there is a possibility that a part of the coating liquid does not flow toward the inner flange but flows to the design surface side along the outer edge of the notch.

  The present invention has been made in view of such a situation, and the object thereof is not to require a special processing man-hour and processing cost, but to the design surface side of the side body outer panel of the paint for panel coating including the electrodeposition paint. It is an object of the present invention to provide a vehicle outer panel superstructure capable of avoiding outflow and contamination of the design surface due to this.

  In order to solve the above-described problems of the prior art, the present invention welds a connection panel connected to other panels including a roof panel on an upper portion of a side body outer panel constituting a design surface of a side panel of a vehicle body. In the upper structure of the outer panel of the vehicle, a recess is provided in the lower part of the welded joint between the upper outer surface of the sidebody outer panel and the connection panel so as to enter the inside of the vehicle body from the joint surface between the sidebody outer panel and the connection panel. ing.

  And in this invention, while the welding joining of the upper outer surface of the said side body outer panel and the said connection panel is comprised by spot welding of several places, the said recessed part is a groove shape along the said several spot weld part A vertical groove extending in the vehicle body height direction is formed between the concave portion and the spot welded portion, and a hole communicating the upper portion of the vertical groove and the inside of the side body outer panel is formed in the side body. It is provided on the outer panel.

  Furthermore, in the present invention, the concave portion is formed by allowing the joint surface of the side body outer panel facing the concave portion to enter the inside of the vehicle body with respect to the design surface, and the connecting panel facing the concave portion. The joint surface protrudes into the recess.

  In the present invention, a sealer is loaded in the opening of the concave portion toward the outer surface of the side body outer panel.

  As described above, the vehicle outer panel upper structure according to the present invention includes the side body outer panel and the lower portion of the welded joint portion between the upper outer surface of the side body outer panel and the connection panel connected to the upper portion of the side body outer panel. Since the concave part that enters the inside of the vehicle body is provided rather than the joint surface with the connection panel, the paint spilled from the weld joint between the upper outer surface of the side body outer panel and the upper part of the connection panel is captured and stored in the concave part. Therefore, even if the paint expands in the drying process after painting, it can be avoided that it flows out to the design surface side of the side body outer panel and contaminates the design surface. This is unnecessary and can save the work man-hours.

  In addition, in the present invention, since the concave portion is formed by bending the side body outer panel or the connection panel, the concave portion can be formed simultaneously with the bending of the side body outer panel or the connection panel by pressing. The processing of the upper structure of the outer panel including the concave portion is less than that of a means for forming a notch for deflecting the paint in a special processing step such as cutting or cutting as in the prior art of Patent Document 1. Man-hours and processing costs can be greatly reduced.

Further, in the present invention, the welded joint between the upper outer surface of the side body outer panel and the connection panel is configured by spot welding at a plurality of locations, and the concave portion has a groove shape along the plurality of spot welds. Therefore, the concave portion extends in a groove shape, so that a large volume of paint can be secured in the concave portion, and the effect of preventing the paint from leaning toward the design surface side of the side body outer panel is increased. It can be shown.
A vertical groove extending in the vehicle body height direction is formed between the concave portion and the spot welded portion, and a hole communicating the upper portion of the vertical groove and the inside of the side body outer panel is formed in the side body outer panel. Since it is provided, it is possible to reduce the area of the mating portion into which the paint soaks, and consequently to reduce the amount of the paint to soak. In addition, the flow of the paint and the air flow into the recesses and the vertical grooves are satisfactorily performed through the holes, and it is possible to prevent problems caused by the painting process. The effect of preventing sagging is increased.

  Further, in the present invention, the concave portion causes the joint surface of the side body outer panel facing the concave portion to enter the interior of the vehicle body with respect to the design surface, and the joint surface of the connection panel facing the concave portion protrudes into the concave portion. Therefore, the concave portion can be formed closer to the inside of the vehicle body of the side body outer panel, and the paint coming out from the mating portion above the concave portion will surely enter the concave portion, and the design surface on the outside of the side body outer panel It can suppress flowing in the direction.

  Furthermore, in the present invention, since the sealer is loaded in the opening of the concave portion toward the outer surface of the side body outer panel, dust and the like can be prevented from accumulating in the concave portion after the vehicle is completed, and the appearance of the vehicle is improved. can do. Furthermore, since the connection panel protrudes into the recess, a sealer can be loaded in the gap between the recess and the connection panel, the amount of the sealer applied can be minimized, and the aesthetics can be improved.
