Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of an automobile body, particularly to the structure of the joint between the lower part of the hinge pillar and the side sill.

[Prior Art] Conventionally, as described in Japanese Utility Model Application No. 58-59673, a reinforcement member is interposed between a side sill outer and a side sill inner as a general joining structure of a side sill part. In some cases, the flange portions of the outer side sill, inner side sill, reinforcement member, and fender panel were joined to each other.

By the way, since the door is attached to the hinge pillar, a large load acts on it, and therefore various structures have been proposed to improve the rigidity of the joint between the hinge pillar and the side sill. The item shown in Figure 1 was found.

Figure 1 shows a cross section of this conventional joint structure. In the figure, 1 is a side sill disposed on the left and right sides of the vehicle body, which has a closed section structure consisting of an inner panel 2 and an outer panel 3. It is a cylindrical body that extends in the longitudinal direction of the vehicle body. A lower end portion of a hinge pillar 4 is joined to the upper surface of the side sill 1, and the hinge pillar 4 consists of a pillar inner 5 and a pillar outer 6, and extends in the vertical direction of the vehicle body.

A hinge reinforcement 7 is disposed within the hinge pillar 4, and the hinge reinforcement 7 has an opening 7a on the right side in FIG.
Its bottom part 7b is joined to the pillar outer 6 of the hinge pillar 4, and its lower wall part 7c is joined to the upper surface of the outer panel 3 of the side sill 1.Although not shown, the hinge A joining flange is formed on the front side of the opening 7 a of the reinforcement 7 in the drawing, and is joined to the pillar inner 5 of the hinge pillar 4 .

However, with this conventional structure, the rigidity of the joint portion was not significantly improved, and as a result, when the door was attached, the tip of the door fell down, making it impossible to open and close the door smoothly.

[Purpose of invention]

The present invention was developed in view of the above-mentioned conventional problems, and it is possible to improve the rigidity of the joint between the hinge pillar and the side sill, and by extension, the rigidity of the vehicle body, and to prevent the door from falling down when the door is installed. The purpose is to provide car body structure.

[Structure of the idea]

In the vehicle body structure of an automobile, the present invention provides a fixing plate having a concave portion consisting of a bottom surface and vertical wall surfaces in front and rear of the bottom surface in a side sill, and disposing the fixing plate such that the concave portion is located below the lower end of the hinge pillar.
An opening is provided above the recess of the side sill, and the front and rear ends of the fixing plate are joined to the upper surface of the side sill, and the bottom of the recess is joined to the lower surface of the side sill.
A hinge reinforcement having a horizontal surface portion whose both ends are joined to the opening side edge of the recessed portion of the fixing plate is disposed, and the horizontal surface portion of the hinge reinforcement connects the upper portion of the recessed portion of the fixing plate to the opening. It is configured to pass through and cover the side sill, thereby creating a knot in the side sill using the fixing plate and hinge reinforcement.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

2 and 3 show an embodiment of the present invention,
In the figure, reference numeral 11 denotes a side sill extending in the longitudinal direction of the vehicle body, and a side sill reinforcement member 8 extending in the longitudinal direction of the vehicle body along the side sill 11 is disposed between an inner panel 12 and an outer panel 13 of this side sill. The upper flange portions 8a, 12a, 13a and lower flange portions 8b, 12b, 13b of the reinforcement member 8 and both panels 12, 13 are interconnected to form two closed cross sections.

Further, a lower end portion of a hinge pillar 14 is joined to the upper surface of the side sill 11, and the hinge pillar 14 has a pillar inner 15 and a pillar outer 1.
6 and extends in the vertical direction of the vehicle body. The portion of the outer panel 13 of the side sill 11 that corresponds to the lower end is cut out in a U-shape to form an opening 13.
c, and the lower end of the pillar inner 15 is joined to the upper flange portion 8a of the side sill reinforcement member 8. The lower end of the pillar outer 16 is bent into an L-shape, and its lower flange 16a is joined to the lower flange 8b of the reinforcement member 8.

A fixing plate 19 is disposed within the side sill 11. The fixing plate 19 is a flat plate having a U-shaped recess 19a. A bottom surface 19f of the recess 19a is joined to the lower surface of the outer panel 13 of the side sill 11 or the lower end of the pillar outer 16. A joining flange portion 19f is bent into the recess 19a.
The fixing plate 19 has a front end 19b located at the dash lower portion 20 and a rear end 19c located at the horizontal portion 16b of the pillar outer 16.
The front and rear ends 19b, 19c are joined to the inner upper surface of the outer panel 13.
The fixing plate 19 has a flange 19e formed by bending the horizontal portion of the fixing plate 19.
3 is bonded to the side wall surface of the

Further, a hinge reinforcement 17 is disposed inside the hinge pillar 14, and the hinge reinforcement 17 is box-shaped with an opening 17a, and its bottom surface 17b is joined to the pillar outer 16. The horizontal surface portion 17c, which is the lower surface, is the opening 13c of the outer panel 13.
through the recess 19 of the fixing plate 19
a, and furthermore, the horizontal surface portion 17c
The joining flange portions 17d formed at both ends of the fixing plate 19 are joined to the edges of the recessed portion 19a of the fixing plate 19.

In the structure of this embodiment configured in this way, a joint is formed by the recessed part 19 of the fixing plate 19 at the joint between the hinge pillar 14 and the side sill 11, and the upper part of the recessed part 19 is connected to the hinge reinforcement 17. Since the joint is covered with a rubber, the rigidity of the joint can be improved and the door can be prevented from falling when the door is attached.

In addition, in the above embodiment, a case has been described in which the outer panel 13 of the side sill 11 is cut out in a U-shape at the joint portion between the hinge pillar 14 and the side sill 11, but in the present invention, it is not necessarily necessary to cut out the outer panel 13 in a U-shape. In short, it is sufficient to provide an opening large enough to cover the concave portion 19a of the fixing plate 19 with the horizontal surface portion 17c of the hinge reinforcement 17. Furthermore, although the side sill reinforcement member 8 was provided in the above embodiment,
In the present invention, the reinforcement member 8 is not necessarily required.

[Effect of idea]

As described above, according to the vehicle body structure of the present invention, a fixing plate having a concave portion consisting of a bottom surface and vertical wall surfaces before and behind the bottom surface is provided in the side sill, and both ends of the fixing plate are provided in the hinge pillar. Since the hinge reinforcement has a horizontal surface portion joined to the opening side edge of the recessed portion of the fixing plate, and the horizontal surface portion covers the recessed portion of the fixing plate, no knots are formed in the side sill. is formed, which improves the rigidity of the joint between the side sill and the hinge pillar and thus the vehicle body.As a result, it is possible to prevent the door from falling down and improve the accuracy of the door installation.
