DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door mirror mounting structure in which a door mirror mounting structure is improved and its mounting rigidity is enhanced.

[0002]

2. Description of the Related Art When a door for an automobile is a door with a frame, as shown in FIG. 4, a reinforcement 33 for mounting a door mirror, which is provided in a belt line direction of a door 38 and is joined to a door frame 34, is shown in FIG. As shown in the figure, the mounting bolt 37 provided inside the door outer panel 32 and fixed to the seat of the door mirror 31 is penetrated through the door outer panel 32 and the door mirror mounting reinforcement 33 to be fixed. 31 is attached. In the case of a press door without a door frame, as shown in FIG. 5, a belt line reinforcement 35 joined to a door outer panel 36 is used as a door mirror mounting reinforcement, and the door mirror 31 is mounted to this by a bolt. . As the door structure as described above, Japanese Utility Model Laid-Open No. 5-62309,
The one disclosed in Japanese Patent No. 34108 is known.

[0003]

However, in the conventional door mirror mounting structure as described above, it is difficult to secure the surface rigidity of the door outer panel side, so that a slight vibration is generated in the door mirror with the vibration from the engine or the like. Therefore, there is a problem that chattering noise and poor mirror visibility occur.
SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the conventional structure, and an object of the present invention is to provide a door mirror mounting structure in which the mounting rigidity of the door mirror is enhanced to suppress generation of vibration.

[0004]

Means adopted by the present invention to achieve the above object is to provide a door mirror mounting link inside the door outer panel of an automobile door formed by a door outer panel and a door inner panel. the reinforcement is provided, in the door mirror mounting structure in which the door mirror mounting portion of the door outer panel reinforced with reinforcements for the door mirror mounting, the Doaauta
Between the upper edge of the panel and the upper edge of the door inner panel.
(A) Provide a recess that forms the belt line at the upper end and join
Of the door outer panel and the door inner panel and the reinforcements and the above-mentioned recess for the door mirror mounting
Joined on the lower surface, and placed on the upper end of the door outer panel.
The upper end of the door outer panel due to the formation of the recess
For curved section and reinforcement for door mirror mounting
Therefore, it is configured as a door mirror mounting structure characterized by forming a horizontal closed section structure .

[0005]

According to the present invention, the door mirror mounting portion of the door outer panel is reinforced by the reinforcement for mounting the door mirror, and the door outer panel is connected to the door outer panel.
Door bells and lines that make up the top panel of the door
Connect As the recess in the section, and the reinforcements door mirror mounting and the door outer panel and door inner panel constituting the belt line of the door
A door mirror mounting structure is formed by joining the above concave portions . Therefore, the rigidity of the door mirror mounting portion is strengthened by joining the door mirror mounting reinforcement, the door outer panel, and the door inner panel, which may cause chattering noise due to engine vibration and the like, resulting in poor mirror visibility. Disappears. Moreover, with the above configuration
Based on the curve of the upper edge of the door outer panel and the door mirror
-Horizontal closed cross section with mounting reinforcement
Since the structure is formed, the strength of the door mirror mounting part is more and more
It will be strengthened more and more .

[0006]

Embodiments of the present invention will be described below with reference to the accompanying drawings to provide an understanding of the present invention. The following embodiments are examples embodying the present invention and do not limit the technical scope of the present invention. Here, FIG. 1 is a sectional view showing a door mirror mounting structure according to an embodiment of the present invention, and FIG. 2 is a perspective view of a door mirror mounting portion according to the embodiment. FIG. 1 shows a cross section of a door mirror mounting portion of an automobile door, in which a door outer panel 3 and a door inner panel 4 are provided.
Thus, an automobile door 5 is formed, and a door mirror mounting reinforcement 2 is disposed inside the door outer panel 3. The reinforcement 2, door outer panel 3, and door inner panel 4 for attaching the door mirror are joined by spot welding or the like at the belt line portion of the automobile door 5. The door mirror 1 has bolts 7 provided on its mounting seat penetrated from the door outer panel 3 to the door mirror mounting reinforcement 2 and is fastened and fixed by nuts 6 from the door mirror mounting reinforcement 2 side. Since the car door 5 on which the door mirror 1 is mounted is moved up and down to open and close the window glass, the door outer panel 3 and the door inner panel 4 cannot be connected at the belt line portion, but the car door 5 on which the door mirror 1 is mounted. The front side of the vehicle is usually a part to which a fixed object such as a triangular window or a corner bracket is attached. Therefore, at this part, the door inner panel 4 can be extended and connected to the door outer panel 3 as shown in FIG. . By extending the door mirror mounting reinforcement 2 to this connection position and joining the door mirror mounting reinforcement 2, the door outer panel 3, and the door inner panel 4 as described above, the rigidity of the door mirror mounting portion is reduced. Be strengthened. Therefore,
Even if engine vibrations or the like are applied to the door mirror mounting portion, chatter or the like does not occur in the door mirror 1. The joint positions of the door mirror mounting reinforcement 2, the door outer panel 3, and the door inner panel 4 in the door mirror mounting section are as follows.
By forming the concave portion as shown in FIG. 1 , not only can it be used as a receiver when the triangular window glass 7 or the corner bracket is installed , but also can be used .
Curved section of the upper end of the door outer panel and the door mirror mounting
The horizontal cross-section structure is formed by reinforcement.
The strength of the door mirror mounting part is further strengthened
Is done .

[0007]

According as the present invention of the above description, with the door mirror mounting portion of the door outer panel reinforced by reinforcements door mirror mounting, the Doaa
Outer panel and door inner panel make up the upper end of the door
To form a recess at the belt line of the door
And, the door mirror mounting structure by bonding with the recess and the reinforcements door mirror mounting and the door outer panel and door inner panel constituting the belt line portion of the door is constituted. Therefore, the rigidity of the door mirror mounting portion is strengthened by joining the door mirror mounting reinforcement, the door outer panel, and the door inner panel, which may cause chattering noise due to engine vibration and the like, resulting in poor mirror visibility. Disappears. Only
Also, based on the above configuration, the door outer panel
With curved part at the upper end and reinforcement for door mirror mounting
Forms a horizontal closed cross-section structure,
The strength of the mounting part is further enhanced .
