Description

[Detailed Description of the Invention] Technical Field The present invention has a first panel and a second panel, and the first panel has at least an end portion of the second panel.
The present invention relates to a panel structure in which a gap is formed between the end portion and the second panel, the gap being substantially orthogonal to the panel and filled with a sealer.

Prior Art Panel structures of the above type are widely used for vehicle bodies, frame structures of houses, and the like. A sealer is filled in the gap between the first and second panels to seal the gap to prevent rainwater or air from flowing through the gap. At that time, if there is no part to receive the filled sealer on the opposite side of the gap where the sealer is injected, the viscosity of the sealer at the time of injection is relatively low. Since this is common, the filled sealer may flow through the gap, making it difficult to reliably close the gap.

Therefore, conventionally, before filling the sealer, putty is packed into the gap to prevent the putty from flowing when the sealer is injected. However, the more putty is packed, the more man-hours are required and the cost goes up. Moreover, because the putty adheres to the end of the first panel, the sealer cannot wrap around the corner edge of this end, and the adhesive strength of the sealer to the first panel is reduced. weaken. Furthermore, since the sealer cannot wrap around the corner edges of the first panel, the corner edges may become more susceptible to rust.

Object The object of the invention is to provide a panel structure of the type mentioned at the outset, which eliminates the above-mentioned conventional drawbacks.

Configuration: In order to achieve the above object, the present invention provides a sealer that is located near the end of the first panel in a portion of the second panel opposite to the side where the sealer is injected, with a gap in between.
We also propose a configuration in which a protuberance is formed that protrudes toward the end.

Examples Examples of the present invention will be described below with reference to the drawings.
In addition, the drawbacks of the conventional technology will be clarified in more detail with reference to the drawings.

Fig. 1 shows the body of a truck, and as shown in Figs. 2 and 3, a floor panel 1, which is an example of a first panel, is located inside the driver's seat, and below it is a floor panel 1, which is an example of a first panel. An extending rear cross member 2 is located there. 3 is a back panel provided at the rear of the driver's cab, and constitutes an example of a second panel. In the intermediate region X in the lateral direction of the body, the floor panel 1 comes into contact with the cross member 2 as shown in FIG.
A floor panel 1 is welded to 5, and a lower end of a back panel 3 is welded to an extension 5a of one flange 5. On the other hand, in the region Y outside the intermediate region X, the back panel 3 is attached to the cross member 2 as shown in FIG.
Although the floor panel 1 is welded to the cross member 2, the floor panel 1 is spaced apart from the cross member 2. (will be revealed later).

By the way, at least the end of the floor panel 1 is substantially perpendicular to the back panel 3, and a slight gap G is formed between the end of the floor panel 1 and the back panel 3. If such a gap G is left unaddressed, the sealing performance of the body will deteriorate, and rainwater and wind will inevitably enter the driver's cabin. Therefore, this gap G is filled with a sealer during vehicle manufacturing. Reference numeral 6 indicates a gun nozzle of the sealer filling device, from which fluid sealer is discharged and injected into the gap G. S
indicates the sealer filled in the gap G.

When filling the sealer as described above, if a part such as the flange 5 of the rear cross member is located directly below the gap on the side opposite to the sealer injection side as shown in Fig. 2, the sealer will be filled. Sheila S is gap G
However, if the floor panel 1 and the rear cross member 2 are spaced apart from each other, the sealer S injected into the gap G will flow downward, as is clear from FIG. 4, which shows an example of a conventional configuration. Since there is no support from below, the sealer S flows downward as shown by the arrow. To deal with this, conventionally, as explained above, prior to filling the sealer, putty with a higher viscosity than the sealer was packed into the gap G to prevent the filled sealer from flowing. This adds the work of packing the putty, which reduces work efficiency during vehicle manufacturing and increases costs.In addition, the sealer does not stick to the edge of the floor panel, which reduces the adhesive strength of the sealer to the panel. However, it is inevitable that there will be disadvantages such as a decrease in Furthermore, if the gap G is large, there is a risk that the putty itself may fall.

Therefore, in the present invention, as illustrated in FIG. 3, a sealant is placed near the end of the floor panel 1 in the part of the back panel 3 on the opposite side of the sealer injection side across the gap G in which the sealer is to be filled. A protuberance 7 is formed that protrudes toward the end.
The raised portion 7 extends along the direction in which the gap G extends. Therefore, the sealer filled in the gap G is received by the raised portion 7, and is prevented from flowing downward. Therefore, there is no need to pack putty before filling with sealer. Furthermore, since the raised portions 7 are formed on the back panel itself, the raised portions 7 can be formed during molding of the panel 3, so that there is no substantial increase in cost.

Further, as in the panel structure shown in FIG. 3, the end of the floor panel 1, which is the first panel, is substantially orthogonal to the back panel 3, which is the second panel, and a sealer is provided in the gap G between them. In the panel structure filled with S, the end of the first panel is separated from the second panel and is in a free state without contacting the second panel, so the sealer S is filled in the gap G. When the sealer S is filled, it is possible for the sealer S to wrap around both corner edges of the end of the first panel. Therefore, the sealer firmly adheres to the panel structure, particularly the first panel, after being cured, and peeling of the sealer can be prevented. Further, although paint is applied to the panel structure by, for example, electrodeposition coating prior to filling with sealer, the paint is difficult to adhere to the corner edges of the panel, resulting in a thin coating film. Therefore, rust is likely to occur here, but after filling with the sealer, the sealer covers and wraps both corner edges of the first panel, so rust can be prevented from forming on both corner edges. However, if the sealer is filled after filling the gap S with putty as in the conventional method, as explained earlier,
As the putty itself adheres to the edge of the first panel,
The sealer S could not wrap around the corner edge of this end, and the above-mentioned advantages could not be fully obtained. In this regard, since the raised portion 7 is used in the present invention, putty is not required, and the above-mentioned advantages can be obtained without any problems.

Although a truck body has been described above as an example of application of the present invention, the present invention is not limited to this and can be applied to other vehicle body parts or other appropriate panel structures. Furthermore, when filling the gap G formed between the first panel 1a and the second panel 3a with sealer from the lateral direction (direction of arrow A) as shown in FIG. Although there was a risk that the sealer S would flow out in direction B, this drawback can be eliminated by forming the raised portion 7 on the second panel 3a on the opposite side to the sealer injection side.

Effects As described above, according to the present invention, the sealer can be prevented from flowing without filling the gap with putty, and the sealer can be firmly attached to the first panel to prevent rust from forming on the corner edges of the panel. It can be prevented.
