Abstract

PURPOSE:To enhance the extent of rigidity in a door hinge setting part without entailing any increase of car weight and cost, by bending a part of reinforcement, bulging it to the side of a pillar outer, and attaching a door hinge to a lap between this bulged part and the pillar outer. CONSTITUTION:A front pillar 1 is constituted of an inner 2 adjoining the inside of a car room, an outer upper 3 to be situated at the outside of this inner 2 and an outer lower 4, and in the inner part, there is provided with a reinforce 5. In this case, a part of this reinforce 5 is bent outward and bulged to both sides of the upper 3 and the lower 4, while an upper end 4a of the lower 4 is joined to the backside of this bulged part 5a, forming a lap A. In addition, a lower end of the upper 3 is joined to an upper end outer surface of the bulged part 5a. And, a channel-form door hinge 6 and a hinge brace 7 are clamped to this lap A so as to be sandwiched from both surfaces with a bolt 8 and a nut 9.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in the structure of a pillar hinge attachment part of an automobile.

(Prior Art) Conventionally, as a sea hinge mounting structure of this type of automobile, there is a structure as shown in FIGS.
is a front pillar inner facing the passenger compartment side, and on the outside of the front pillar inner 12 are a front pillar outer upper 13 and a front pillar outer lower 1.
4 are provided with their parts overlapped and welded together. And front pillar outer upper 1
A door hinge 16 having a U-shaped cross section and a hinge place 1 are located at the overlapping part N between the door hinge 3 and the front pillar outer lower 14.
bolts 18. and 7 sandwich the overlapping portion A'.
18 and NAND 19. It is fastened in a three-ply manner at 19. Incidentally, a reinforcement 15 is provided between the front pillar inner 12 and the front pillar outer 13 and 14 to increase the rigidity of the front pillar.

(Problems to be Solved by the Invention) However, in the above conventional front pillar hinge attachment structure, both front pillar outer uppers,
Because the thickness of the lower plates 13 and 14 is small, the door hinge 16
It was not possible to increase the rigidity of the overlapping part N, which is the mounting part, and problems such as door falling were likely to occur. If this problem is not addressed (increasing the thickness of the outer pillars 13 and 14 of both front pillars, the weight of the vehicle will increase significantly).

Further, if the plate thicknesses of both front pillar outer members 13 and 14 are small, deformation occurs in the overlapped portion N, which also causes a problem that abnormal noise is generated in the overlapped portion A'.

The present invention has been made in view of the above problems, and its purpose is to increase the rigidity of the door hinge mounting portion and solve problems such as door sliding, etc., without increasing the weight of the vehicle or increasing costs. The present invention provides a pillar hinge mounting structure for an automobile.

(Means for Solving the Problems) In order to achieve the above object, the present invention bends a part of the reinforcement interposed between the pillar inner and the pillar araku to bulge toward the front pillar outer side. The bulging part of the reinforcement and the front pillar outer are overlapped to form an overlapping part, and a door hinge is attached to the overlapping part.

(Function) Since the rigidity of the overlapping part is increased by the thick reinforcement, problems such as deformation of the door hinge attachment part and door falling do not occur.

(Example) An example of the present invention will be described below based on the accompanying drawings.

FIG. 1 is a broken cross-sectional view showing a pillar hinge attachment structure according to an embodiment of the present invention, and FIG. 2 is a perspective view of the main part of FIG. It is composed of a pillar inner 2, a front pillar outer upper and a lower 3.4 located outside the front and the pillar inner 2, and a thick reinforcement 5 is provided inside to increase rigidity. A part of this reinforcement 5 is bent outward and bulges toward the front pillar outer upper and lower 3 and 4 sides, and the front pillar outer lower 4 is formed on the back side of this bulging portion 5a. As shown in the figure, the upper end portions 4a of the two are joined by spot welding to form an overlapping portion A. The lower end of the front pillar outer upper 3 is bonded to the outer surface of the upper end of the bulge 5a of the reinforcement 5 by spot welding.

A channel-shaped door hinge 6 and a hinge place 7 are fastened to the overlapping portion A by bolts 8.8 and nuts 9.9 so as to sandwich them from both sides. Note that a door (not shown) is attached to the door hinge 6 so that it can be opened and closed.

In the above, since the overlapping part A is composed of the thick reinforcement 5, the rigidity of the overlapping part, which is the hinge attachment part, is increased, and problems such as deformation of the overlapping part and door falling are eliminated. . In addition, these effects can be achieved without increasing the thickness of the front pillar inner 2, front pillar upper, and lower 3.4, so there is no increase in vehicle weight or cost.

Although the present embodiment has been described using a front pillar as an example, the present invention is not limited to this, and can be similarly applied to a center pillar and the like.

(Effects of the Invention) As is clear from the above explanation, according to the present invention, the hinge mounting portion is configured using reinforcement rationally, so that the rigidity of the door hinge mounting portion is improved without increasing the vehicle body size and cost. This can solve problems such as doors falling down.
