Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a body of a hinge attachment portion that prevents electrodeposited liquid from remaining on the rigid bead of a door hinge.

A door is attached to a vehicle via a door hinge. For example, in the vehicle shown in Figure 1,
Door hinges are attached to the parts shown in A to D, so that the front door 1 or the rear door 2 can be opened and closed (in the case of A of the front door 1, it is disclosed in Japanese Utility Model Application No. 59-72171). ). Of these door hinges, the door hinge attached to section D is shown in FIG. As shown in the figure, a door hinge 4 is attached to the center pillar 3 with three bolts, and the door hinge 4 is connected to the rear door 2 with two bolts. door hinge 4
In this example, a body side hinge attached to a body side such as a center pillar and a door side hinge attached to a door are rotatably connected.
Among these, the body side hinge 4' has a substantially flat base 4a with a raised portion 4'' formed at the horizontal end in the attached state, as shown in FIG.
and a connecting part 4b that supports and connects the door side hinge as a rotating part formed on the rising part 4'', and a connecting part 4b of the base 4a is formed approximately at the center of the base 4a including the rising part 4''. A rigid bead 6 is provided which partially protrudes in the horizontal direction to increase rigidity. The reason for forming the rigid bead 6 is as follows. The first purpose is to increase the strength of the body side hinge 4a against bending, since a large bending moment is applied to the body side hinge 4a in the direction of the arrow in the figure when the door is overrun when the door is opened. The second reason is to prevent rust since rust is likely to occur in areas where metals are in direct contact with each other (metal touch).

However, the following problems occur due to the rigid bead being formed on the body side hinge. Generally, after the door is attached to the body via the door hinge, the vehicle is placed in an electrodeposition furnace to deposit an electrodeposition liquid, and then an undercoat and a topcoat are applied. When depositing the electrodeposition liquid, the electrodeposition liquid that has entered the rigid bead does not flow out completely and a portion remains because the rigid bead is formed in a horizontal direction. Then, after applying the undercoat, the remaining electrodeposition liquid flows out due to heat or vibration, resulting in the disadvantage that the topcoat paint may not adhere or traces of the electrodeposition liquid may remain.

To solve this problem, the lower part of the rigid bead 6 of the door hinge 7 can be inclined as shown in FIG. 4, but there is a problem that it becomes difficult to shape the tip 9 of the rigid bead 6. .

Therefore, an object of the present invention is to provide a body for a hinge mounting portion that eliminates such drawbacks.

The structure of the present invention to achieve this purpose is as follows:
A substantially flat base having a rising portion formed at the horizontal end, and a connecting portion formed on the rising portion to support and connect the rotating portion, and approximately at the center of the base including the rising portion. The body side hinge is equipped with a bead that increases rigidity by making a part of the base protrude horizontally.
The hinge is attached to a wall of the vehicle, and is characterized in that an outflow groove is formed between the hinge and the wall of the vehicle, extending downward from the lower part of the space surrounded by the bead and the wall of the vehicle and communicating with the outside. do.

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings. It should be noted that the present invention is a partial improvement of the structure of the conventional door hinge attachment part, so the same parts are given the same reference numerals and only the different parts will be explained.

FIG. 5 is a view of the center pillar from the side of the vehicle, with reference numeral 11 indicating the surface of the center pillar 3 on the front seat side, and 12 indicating the surface on the rear seat side. Further, this body side hinge 4a is for a rear door, and the direction indicated by the arrow in the figure is the front of the vehicle. FIG. 6 is a sectional view taken along the line E--E in FIG. 5. As shown in the figure, the center pillar 3 is composed of a center pillar outer 13 and a hinge reinforcement 14, and includes a body side hinge 4a.
is firmly attached to the center pillar 3 with bolts 17. A space 15 is formed between the rigid bead 6 and the center pillar outer 13, and a recess is provided in the center pillar outer 13 on the body side of the hinge mounting portion so that the liquid that has flowed into the space 15 flows out. An outflow groove 16 is formed. The outflow groove 16 is formed downward from the lower part of the space 15 to the outside of the body side hinge 4a. Therefore, the liquid that has flowed into the space 15 flows out in the direction indicated by the arrow in the figure. Note that the outflow groove 16 is not limited to the position shown in FIG. 5, but may be provided at a position shifted in the left-right direction on the paper.

As described above in conjunction with the drawings, according to the present invention, an outflow groove is formed in the body to which the door hinge is attached, through which the liquid that has flowed into the rigid bead flows out, so that the electrodeposited liquid does not remain in the rigid bead. Coating defects caused by the electrodeposition liquid remaining in the rigid bead flowing out are eliminated.
