DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention relates to a lower end structure of a front window panel for an automobile, and more particularly to a wiper housed under a hood.

(Prior Art) As a conventional lower end structure of a front window panel for an automobile, there is, for example, one shown in FIG. That is, reference numeral 100 is a front window panel provided in a front window section for an automobile, and the air box section 1 is provided at a lower terminal of the front window panel 100.
01 is joined and fixed to the rear edge of the cowl panel 102 constituting the upper surface. The front window panel 100 is inclined substantially linearly to the panel lower end so that the lower end side thereof projects toward the front of the vehicle. On the other hand, 103 is a hood,
The rear end covers the cowl panel 102,
The wiper blade 104 when not in operation is stored under the hood 103. That is, the wiper blade 104 is stopped in a horizontal state along the lower edge of the front window panel 100 when not operating, and passes through the gap B ₁ between the rear end of the hood 103 and the surface of the front window panel 100 when operating. It was designed to be taken in and out from the storage position below the hood 103. In addition, as such a front window panel lower end structure,
For example, it is described in “Automotive Engineering Flight Section <Vol. 6>” issued by the Society of Automotive Engineers of Japan.

(Problems to be Solved by the Invention) However, in such a conventional example, the positions of the hood 103 and the air box portion 101 remain unchanged, and the front window panel 10 is expanded to expand the front space of the vehicle compartment S ′.
When the lower end fixing portion of 0 is shifted forward, the gap B ₂ between the rear end of the hood 103 and the front window panel 100 becomes narrower as shown by the chain double-dashed line in FIG.
Can no longer be stored. Further, from the lower end of the front window panel 100 to the air box portion 101
The dimension A ′ to the front end becomes short, the volume of the momentum air box portion 101 becomes small, and the air introduction efficiency also decreases. Therefore, in order to allow the wiper blade 104 to be stored and to secure the volume of the air box portion 101 to expand the vehicle interior space, the front window panel 1
The air box portion 101 and the hood 103 have to be moved forward by an amount corresponding to the shift of 00 to the front, and the overall length of the vehicle body is lengthened accordingly and the vehicle body is unnecessarily enlarged.

The present invention was made in order to solve the above-mentioned problems of the prior art. The purpose is to bend the lower end of the front window panel to effectively use the space near the air box, Accordingly, it is an object of the present invention to provide a lower end structure of a front window panel of an automobile capable of expanding a vehicle interior space while ensuring a wiper and an air box function.

(Means for Solving Problems) In order to achieve the above object, according to the present invention, a lower end of a front window panel whose upper end is inclined so as to project toward the front of the vehicle is located above an air box part. In the structure of the lower end portion of the front window panel for an automobile, the lower end portion of the front window panel is substantially vertical and is fixed to the upper end of the air box portion by the rear end portion of the hood and the wiper is stored under the hood when not in operation. It is characterized in that it has a bent portion bent downward in the direction, and the lower end of the bent portion forms a vertical surface portion which faces downward in a substantially vertical direction.

(Operation) Since the lower end of the front window panel has a bent portion in which the lower end of the front window panel is bent substantially vertically downward, and the lower end of the bent portion forms a vertical surface portion that is directed substantially vertically downward, If the lower end fixing position of the panel is the rear end of the upper part of the air box part as in the conventional case, the window panel can be advanced by the amount of bending the lower end of the front window panel without changing the front and rear width of the air box part. Moreover, since the lower end of the front window panel has the vertical surface portion, the space surrounded by the vertical surface portion, the upper portion of the air box portion, and the hood forms a wiper storage space.

(Example) Below, this invention is demonstrated based on the Example shown in figure. In FIG. 1 showing the structure of the lower end portion of a front window panel for an automobile according to the first embodiment of the present invention, reference numeral 1 is a front window panel made of glass or transparent resin, and the lower end side of the front window panel 1 faces the front of the vehicle. It is attached so that it can be projected. The lower end portion of the front window panel 1 is fixed to the rear end edge of the air box portion 2 of the vehicle body. On the other hand, the rear end of the hood 3 is covered above the air box portion 2 so that the wiper blade 4 of the wiper when not in operation is stored below the hood 3.

The air box portion 2 is formed into a closed boss cross-section by joining a cowl panel 5 having a substantially inverted L-shaped cross section and a dash upper panel 6 having an L-shaped cross section. The dash lower panel 7 is arranged in a row.
Then, for example, air is introduced into the air box portion 2 from an air guide port provided in the cowl panel 5.
On the other hand, the hood 3 includes an outer panel 31 on the front surface side and an inner panel 32 on the rear surface side.
A gap is provided between the upper surface and the cowl panel 5 to prevent interference between the hood 3 and the cowl panel 5.

On the other hand, the lower end of the front window panel 1 is bent substantially vertically downward, and the back surface of the bent portion 8 at the lower end of the panel is adhesively fixed to the cowl panel 5. That is, the joint flange portion 9 with the dash upper panel 6 at the rear edge of the cowl panel 5 is bent substantially at a right angle to the upper surface of the cowl panel 5, and the joint flange portion 9 is bent at the lower end of the front window panel 1. The back surface of the portion 8 is adhesively fixed with an adhesive 10. The corner portion 82 of the lower end bent portion 8 of the front window panel 1 is formed into a smoothly rounded curved surface so that the wiper blade 4 can easily move. The lower end of the bent portion 8 extends substantially up to the upper surface of the cowl panel 5, and the lower end of the bent portion 8 and the cowl panel 5
A slight play is provided between the upper surface and the upper surface to absorb a dimensional error.

When the wiper is not operating, the wiper blade 4 is held horizontally along the lower end of the front window panel 1 and is in contact with the surface of the vertical surface portion 81 of the bent portion 8. That is, the wiper storage portion 11 for storing the wiper blade 4 between the inner panel 32 of the hood 3, the vertical surface portion 81 of the bent portion 8 of the front window panel 1 and the upper surface of the cowl panel 5 as the upper portion of the air box portion.
Are formed. On the other hand, the rear end hemming portion 33 where the inner panel 32 and the outer panel 31 at the rear end of the hood 3 are joined, and the vertical surface portion 8 of the lower end of the front window panel 1
1 and 1 are separated from each other by a predetermined distance B in the vehicle front-rear direction so that the wiper blade 4 can pass therethrough. The height position of the corner portion 82 of the bent portion 8 is slightly lower than the height position of the rear end hemming portion 33 of the hood 3. Further, on the back surface of the lower end portion of the front window panel 1, there is a print portion 12 such as a black print from the vertical surface portion 81 of the bent portion 8 to the corner portion 82 and a position corresponding to the height position of the rear end hemming portion 33 of the hood 3. It is provided.

In the lower end structure of the front window panel for an automobile having the above-mentioned configuration, when the wiper is actuated, the wiper blade 4 stored in the wiper storing portion 11 below the hood 3 rotates about a wiper pivot (not shown). The wiper storage unit 11 is pushed outward to wipe the front window panel 1 surface. When the wiper blade 4 comes out of the wiper storage portion 11, the wiper blade 4 reaches the inclined surface portion 1a from the vertical surface portion 81 of the bent portion 8 at the lower end of the front window panel 1 through the corner portion 82. The mounting angle and the like of the wiper blade 4 are set in accordance with the curved surface shape of the inclined surface portion 1a of the front window panel 1, the position of the wiper pivot, and the like so that the entire wiping region can be wiped smoothly.

Here, comparing this embodiment with the conventional example shown in FIG. 3, the dimension A from the lower end fixing portion of the front window panel 1 to the front end of the air box portion 2 is the same as the conventional one, and the inclination angle of the front window panel 1 is further changed. If the same applies, the window panel 1 can move forward by C, and the interior space of the vehicle interior S can be increased.

Further, since the adhesive fixing portion at the lower end of the front window panel 1 becomes the adhesive between the vertical surface portion 81 of the bent portion 8 and the joining roughening portion 9 at the rear end of the air box portion 2, the fixing work at the lower end of the window panel 1 is performed by the cowl panel. 5. The work is easy because it is sufficient to press the bent portion 8 toward the rear joint roughened portion 9 using the upper surface as a guide. In addition, the wiper storage unit 11
, The wiper blade 4 is difficult to see from an obliquely upper position, and the appearance is improved.

FIG. 2 shows a lower end structure of an automobile front window panel according to a second embodiment of the present invention. In the second embodiment, the bent portion 18 of the lower terminal of the front window panel 1 is formed separately, assuming that the same components as those in the first embodiment are designated by the same reference numerals. It was done. That is, the straight inclined surface portion 1a of the front window panel 1 is made of ordinary glass because it is easy to form, and the curved bent portion 18 that is difficult to form is made of resin. In this case, the joint flange portion 9 at the rear end of the air box portion 2 is formed in an arc shape according to the curvature of the bent portion 18, and the rear surface side of the lower end portion of the inclined surface portion 1a is also adhesive from the rear surface of the bent portion 18. It is adhered and fixed by 10. The rest of the configuration and operation are the same as in the first embodiment, so description will be omitted.

(Effects of the Invention) The present invention has the above-described configuration and operation, and has a bent portion in which the lower end of the front window panel is bent downward in a substantially vertical direction, and the lower end of the bent portion is substantially vertical. Since it has a vertical surface that faces downward in the direction, if the lower end of the front window panel is fixed to the rear end of the upper part of the air box as before, the lower end of the front window panel can be adjusted without changing the front and rear width of the air box. The window panel can be moved forward by the amount of bending, and since the lower end of the front window panel has a vertical surface, the space surrounded by the vertical surface, the upper part of the air box, and the hood provides a wiper storage space. Will be completed. Therefore, it is possible to advance the window panel and expand the vehicle compartment space without impairing the air introduction function and the wiper function of the air box portion.
