Description

[Detailed Description of the Invention] The present invention relates to a front body structure of an automobile.

A wiper device is attached to the front window of an automobile to improve forward visibility in rainy weather. This wiper device consists of a wiper arm shaft to which a wiper blade is attached for cleaning the front window surface, and a wiper motor.

However, conventionally, the wiper arm shaft has been attached to a front panel, and the wiper motor has been attached to a dart board or instrument panel that is separate from the front panel. and,
Since these panels are made of thin steel plates, they cannot be said to have sufficient strength, and the front panel, where the wiper arm shaft is attached, bends or deforms due to the reaction force of the wiper blade's wiping resistance. The positional relationship between the wiper blades was worn, and the initial wiping range of the wiper blade could not be achieved, and noise was generated, making it impossible for the wiper device to operate properly.

The present invention has been developed in view of the drawbacks of the conventional examples, and a reinforcement which also serves as a mounting member for the wiper device is welded between the front panel and the instrument panel or dart board. The above-mentioned wiper arm shaft and wiper motor are attached to the forcement.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a front body structure for attaching a wiper device of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a perspective view of the front of the vehicle, Figure 2 is a sectional view taken along line X-X in Figure 1, and Figure 3 is Y-Y in Figure 1.
It is a sectional view taken along the line.

In FIG. 1, 11 is a wiper motor attached to one side of the reinforcement 5, 9 is a wiper arm to which a wiper blade 10 is rotatably attached, and 15 is a front window.

In FIG. 2, a front panel 1 is fixed to an instrument panel or dash board (hereinafter simply referred to as the instrument panel) 2 by spot welding at the upper part, and a windshield 4 of a front window is attached via a weather strip 3.

As shown in FIG. 3, between the front panel 1 and the instrument panel 2, a reinforcement 5 whose upper section is approximately U-shaped is provided, and the right edge (rear edge) of the approximately U-shaped cross section is provided. is spot welded to the instrument panel 2 at multiple locations. Further, the left edge (front edge) of the substantially U-shaped cross section of the reinforcement 5 is located at a distance from the front panel 1, and a link 6 having a pivot 7 is attached to the front edge of the reinforcement. The attached wiper arm shaft 8 is pivoted, and a wiper arm 9 is attached to the front part of the wiper arm shaft 8.

In FIG. 3, a portion of the rear edge of the reinforcement 5 is extended downward, a wiper motor 11 is attached to the extended portion, and a link 1 having a pivot 14 is attached to the outer end of the motor shaft 12.
3 is installed.

A link 6 having a pivot 7 attached to the wiper arm shaft 8 shown in FIG. 2, a link 13 having a pivot 14 attached to the motor shaft 12 shown in FIG. The link mechanism consists of a connecting rod that connects and operates a crank.

Therefore, when the wiper motor 11 operates, the link 13 and the pivot 14 attached to the link 13 rotate together with the motor shaft 12, and this rotational motion is converted into a reciprocating rotational motion via the connecting rod and transmitted to the wiper arm shaft 8. The wiper arm 9 and wiper blade 10 swing.

Although Fig. 1 shows an example in which three wiper devices are installed, the swinging of the left and right wiper arms and wiper blades is caused by the pivots of the links attached to these wiper arm shafts and the central wiper device. Motor shaft 12 shown in FIG.
This is done by connecting the pivot 14 of the link 13 attached to the wiper motor 11 with a connecting rod and transmitting the rotational movement of one wiper motor 11.

According to the front body structure of the present invention having the above configuration, since the wiper device is attached to the reinforcement, its retention is sufficient in terms of strength, and the wiper motor generated by the reaction force of the wiping resistance of the wiper blade when the wiper device operates and eliminates deflection or deformation of the wiper arm shaft attachment part,
This eliminates noise and unwiped areas caused by friction between the wiper arm shaft and the wiper motor motor shaft caused by the amount of deflection or deformation, and since the installation of the wiper device is an integrated reinforcement, the wiper arm shaft and wiper motor Installation can be done accurately, and durability and installation accuracy can be improved.
