Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching a door to a front pillar of a vehicle body.

[0002]

2. Description of the Related Art As a conventional structure of this type, for example, according to Japanese Utility Model Laid-Open No. 63-16236, a bulkhead is provided on a plate-like reinforcement to be welded to a hinge mounting portion in a pillar, and a peripheral edge of the bulkhead is provided. It is known to improve the mechanical strength of the pillar by welding it to the inner surface of the pillar.

[0003]

In the case of a vehicle equipped with a sunroof, an annular gutter is provided in the periphery of the opening of the roof so that rainwater does not enter the vehicle through the opening of the sunroof, and the rainwater collected in the gutter is drained. It is configured to drain through a pipe. The drain pipe is inserted into the front pillar so as not to be exposed on the outer surface of the vehicle body or the inside of the vehicle. However, when the inside of the pillar is closed by a bulkhead like the above-mentioned conventional one, particularly when such a configuration is applied to the front pillar However, there is a problem that the drain pipe cannot be inserted due to the bulkhead.

Therefore, in view of the above problems, it is an object of the present invention to provide a structure in which a drain pipe can be inserted even if a bulkhead is provided in the front pillar.

[0005]

In order to achieve the above object, the present invention is to mount a nut in a box-shaped front pillar formed by combining an outside panel and an inside panel, and install the nut in the nut. In a structure in which a pair of upper and lower hinges of a door are screwed from the side panel side, a plate-shaped bulkhead portion fixed over substantially the entire circumference in the front pillar and a part of the peripheral edge of the bulkhead portion are fixed. A reinforcing member, which is formed by bending and has a nut holding portion for holding the nut, is attached to each of the pair of hinges so as to be separated from each other in the longitudinal direction of the front pillar, and to the bulk head portion of each reinforcing member. It is characterized in that an opening is provided and at least the opening of the reinforcing member attached to the upper side is formed in a funnel shape that is narrowed downward.

[0006]

The force acting on the front pillar from the door side acts as a concentrated load on the upper and lower two parts where the hinge of the door is attached. By holding the nut for screwing the hinge integrally with the bulkhead, the positional relationship between the nut and the bulkhead does not shift and the mechanical strength of the front pillar is increased and concentrated load is applied via the bulkhead. Can be effectively dispersed on the inside panel side. Further, if the bulkhead portion is fixed over substantially the entire circumference in the front pillar, even if an opening is provided in the bulkhead portion, the mechanical strength is reduced only slightly. Then, the drain pipe can be inserted into the front pillar through the opening. By the way, when the drain pipe is inserted into the front pillar from the roof side, if the bulkhead portion is simply provided with an opening, the drain pipe is caught on the upper surface of the bulkhead and is difficult to be inserted into the opening. Therefore, by forming the opening in the shape of a funnel that narrows downward, the funnel-shaped slope serves as a guide to guide the tip of the drain pipe into the opening. It suffices that the drain pipe is inserted between the upper and lower bulkhead parts until the tip is positioned. Therefore, at least the opening of the bulkhead part to be mounted on the upper side is formed in a funnel shape. Then, the rainwater discharged from the drain pipe is discharged from the lower end portion of the front pillar to the outside of the vehicle through the opening of the bulkhead portion attached to the lower side.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, reference numeral 1 is a front pillar of a vehicle body, and a wheelhouse upper member 2 is extended forward. Further, a pair of upper and lower hinges 31 and 32 provided on the front end surface of the door 3 are screwed to the front pillar 1 by two bolts 33.

Referring to FIG. 2, a front pillar 1 is formed by welding an outside panel 11 and an inside panel 12 to each other so as to form a box-shaped space. In addition, the stiffener 1 having substantially the same shape as the outside panel 11 is provided in the front pillar 1 for reinforcement.
3 and the reinforcing member 4 shown in FIG. 3 and the reinforcing member 5 shown in FIG. 5 are fixed. By the way, the reinforcing member 4 is provided with a bulkhead portion 40 and a nut holding portion 42 bent downward from an end edge of the bulkhead portion 40. As shown in FIG. The opening 41 is formed in the shape of a funnel that is narrowed downward, and the funnel-shaped slope 41a is formed.
Are formed. A nut 43 is fixed to the back surface of the nut holding portion 42 so as to be screwed with the bolt 33 and screw the upper hinge 31. Similarly, the bulkhead portion 50 and the nut holding portion 52 bent downward from the end edge of the bulkhead portion 50 are also formed on the reinforcing member 5, and the bolt holding member 52 is provided on the rear surface thereof. 33
A nut 53 that is screwed onto the lower hinge 32 and is screwed to the lower hinge 32 is fixed.

In order to assemble the front pillar 1, first, the stiffener 13 is provided with the reinforcing members 4 and 5.
When the stiffener 13 is subsequently welded to the outside panel 11, the reinforcing members 4 and 5 and the stiffener 13 are welded.
And the outside panel 11 are overlapped with the nut holding portion 42
・ Spot weld the 52 part to fix the three parts to each other. Next, after applying an adhesive to the side surfaces of the reinforcing members 4 and 5 that are fixed to the inside panel 12, the inside panel 12 is put together to form a flange portion where the inside panel 12, the stiffener 13, and the outside panel 11 overlap. Spot welding. In this way, the inside panel 12
When is welded, the surface of the reinforcing members 4 and 5 coated with the adhesive is pressed against the inner surface of the inside panel 12, and the curing of the adhesive fixes the reinforcing members 4 and 5 also to the inner surface of the inside panel 12. The reinforcing member 4 has a nut 44 separately.
Are held in advance, and the front pillar pipe bracket 14 is screwed by using the nut 44.

When the front pillar 1 is assembled in this way, the hinges 31 and 32 are screwed by the bolts 33 as described above, and the door 3 is attached to the outside panel 11 side of the front pillar 1. Further, a drain pipe from the sunroof (not shown) is inserted into the front pillar 1 from the roof side. The bulkhead portion 40 in which the tip of the drain pipe is on the upper side
When reaching, the tip of the drain pipe is guided toward the opening 41 along the slope 41a and passes through the opening 41 without being caught. In this embodiment, the drain pipe may be inserted until the tip of the drain pipe is located between the reinforcing members 4 and 5, and therefore, the opening 5 of the lower bulkhead 50 may be inserted.
Although 1 is not formed in a funnel shape, if it is necessary to further insert the drain pipe into the opening 51, the opening 51 may be formed in a funnel shape like the upper opening 41.

[0011]

As is apparent from the above description, according to the present invention, the mechanical strength of the front pillar can be increased and the drain pipe can be smoothly inserted into the front pillar.
