Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a waterproof structure for a door visor for an automobile.

2. Description of the Related Art A general door visor is mounted on an upper portion of a door by mounting brackets provided at appropriate intervals on an upper portion of a back surface of a resin visor body. The mounting bracket is attached to the visor body by welding a central portion thereof.

[Problem to be Solved by the Invention] In the case of the above structure, since the welding point is located at the center of the mounting bracket, a gap may be formed between the visor main body and the upper part of the mounting bracket. Could invade.

Therefore, the present invention is to prevent the intrusion of rain without making much changes to the conventional process.

[Means for Solving the Problems] In order to solve the above problems, a door visor according to the present invention welds a metal mounting member to a resin visor body, and also mounts a mounting member upper portion above a welding point and a visor body. In the door visor having a gap formed between the visor body and the mounting member, an elastic seal member provided above the welding point of the mounting member is interposed between the visor body and the mounting member, and the elastic seal member seals the gap. It is characterized by having done.

[Effect of the Invention] Since an elastic seal member is interposed on the upper part of the mounting member, when the mounting member is welded to the resin visor body, the upper part is connected to the door visor via the elastic seal member provided in advance in this part. In close contact. Therefore, the space between the visor body and the upper portion of the mounting member is reliably waterproofed.

In addition, the visor body is made of resin, and a metal attachment member that curves in a convex shape is attached to the visor body, so that a gap is formed due to a difference in molding accuracy, etc.
This gap can be sealed with an elastic sealing member.

In addition, since only the elastic seal member is provided above the mounting member prior to welding, there is almost no need to change the conventional mounting member mounting process.

Further, since the welding direction and the direction in which the elastic seal member is compressed are the same, the elastic seal member can be easily crushed and sealed simply by welding.

FIG. 1 to FIG. 3 show an embodiment. FIG. 1 is an exploded view showing the appearance of a door visor, and a visor body 1 is shown.
Attachment part 2 rising upward on the upper part of the wall to form a wall shape
The mounting brackets 3 are welded at appropriate intervals to the back surface of.

The mounting bracket 3 is an example of a mounting member in the present invention,
A mounting hole 4 is formed in the central portion 3a, and a pair of opposed bent portions 3b extending in the same direction up and down, sandwiching the central portion 3a.
An elastic seal member 5 is attached to an upper portion 3c located above the attachment hole 4 in the central portion 3a.

The mounting bracket 3 is an example of a mounting member in the present invention,
Further, due to the difference in molding accuracy from the visor body 1 made of metal and resin, as is apparent in FIGS.
The central portion 3a has a smaller radius than the back surface of the mounting portion 2 to which the welding is performed, and has a curved surface protruding toward the mounting portion 2 side.

A mounting hole 4 is formed in a central portion 3a of the mounting bracket 3, and a pair of opposing bent portions 3b extending upward and downward in the same direction with respect to the central portion 3a are formed. An elastic seal member 5 is attached to the upper portion 3c, which is a position higher than that.

The mounting bracket 3 is welded to the back surface of the mounting portion 2 by a known welding material 6 passed through the mounting hole 4. At this time, a gap 3d is formed between the upper and lower portions of the central portion 3a convexly curved toward the mounting portion 2 and the mounting portion 2, and the upper portion 3c of the gap located above the mounting hole 4 which is a welding point. The portion on the side is sealed with an elastic seal member 5. Therefore, in FIG. 3, only the lower gap 3d is visible.

2 and 3 are cross-sectional views for explaining this mounting process. First, as shown in FIG. 2, the welding material 6 is inserted into the mounting hole 4 and pressed against the back surface of the mounting portion 2, and The welding material 6 is welded to the mounting portion 2 by appropriate means such as sonic welding.

Then, as shown in FIG. 3, the elastic seal member 5 is fixed in a state of being pressed against the back surface of the mounting portion 2, and at the same time, the elastic seal member 5 is crushed between the mounting portion 2 and the mounting bracket 3. Seal the gap between them.

In addition, the elastic sealing member 5 may be solid or liquid adhesive type.

Next, the operation of the present embodiment will be described. In FIG.
Since the gap between the back surface of the mounting portion 2 and the upper portion of the mounting bracket 3 is sealed by the elastic sealing member 5, the rain 7 cannot enter the vehicle interior from this gap, and the surface of the mounting portion 2 and the surface of the visor main body 1. And dripping outside the cabin.

Therefore, the waterproofing of the passenger compartment is more reliable. In addition, in this embodiment, the elastic seal member 5 need only be attached to the upper surface of the mounting member 3 prior to welding of the mounting member 3, so that only a small amount of work needs to be added to the conventional process of mounting the mounting member 3. Good workability.

In addition, since the visor body 1 is made of resin, and the mounting member 3 to be mounted on the visor body 1 is made of metal whose central portion 3a is convexly curved toward the mounting portion 2, the difference in the molding accuracy between the visor main body 1 and the visor main body 1 is made by combining them. A gap is formed between the attachment member 3 and the back surface of the attachment portion 2 due to the above factors. The elastic seal member 5 can easily seal the space above the welding point in the gap.

Furthermore, since the welding direction and the direction in which the elastic seal member 5 is compressed are the same, the elastic seal member 5 can be easily compressed and sealed simply by welding.

[Effect of the Invention] In the present invention, the elastic seal member is provided on the upper portion of the mounting member, and when the mounting member is welded to the visor main body, the gap formed between the upper portion and the visor main body is sealed by the elastic seal member. Thus, it is possible to more reliably prevent water from entering the vehicle interior from the gap.

In addition, the visor body is made of resin, and a metal mounting member whose welding portion is convexly curved toward the mounting portion is attached to the visor body, so that a gap is formed due to a difference in molding accuracy and the like. Since the gap can be sealed by the elastic sealing member, the combination of the resin visor body and the metal mounting member is facilitated, and the molding of each member does not need to be so high in accuracy.

In addition, since only an elastic seal member is provided above the mounting member prior to welding, there is almost no need to change the conventional mounting member mounting process, and the workability is good.

Furthermore, since the welding direction and the direction in which the elastic seal member is compressed are the same, the elastic seal member can be easily compressed and sealed simply by welding.
