Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a front hood hinge structure for opening and closing a front hood on a body.
[0002]
[Prior art]
The front hood (see reference numeral 2 in FIG. 1) covers an engine room and is attached to the body (see reference numeral 1 in the figure) so as to be opened and closed in the vertical direction. The front hood includes a hood main body, a hood hinge (see reference numeral 3 in the figure), a striker, and the like. This hood main body is generally a hood assembly in which an outer panel and an inner panel are matched to a closed cross-sectional shape and a flange portion on the entire circumference is hemmed.
In the painting process, the front hood is immersed in the electrodeposition tank alone or attached to the body, and an electrodeposition liquid or the like is put into the hood main body through a plurality of openings provided in the inner panel. Rust prevention treatment is applied to each back (inside) of the inner panel. As shown in FIG. 9, drain holes 32 for removing the electrodeposition liquid and the like are provided at both corners of the rear end of the inner panel 31.
[0003]
[Problems to be solved by the invention]
If the hood hinge 33 is placed at the same position as the drain hole 32, the hood hinge 33 will block the drain hole 32. Therefore, as shown in FIG. It is necessary to lay out, and it is difficult to reduce the size and weight of the hood hinge 33 due to layout restrictions. Moreover, the distance A from the rotation center part 34 of the hood hinge 33 to the fastening part 35 to the inner panel 31 becomes long, which is disadvantageous in terms of rigidity.
The present invention has been made in view of such a situation, and an object of the present invention is to provide a front hood hinge structure that can ease the size reduction of the hood hinge by relaxing the restrictions on the layout of the hood hinge.
[0004]
[Means for Solving the Problems]
In order to solve the above problems, the present invention forms a front hood body by combining an outer panel and an inner panel, a hood hinge is disposed on the inner panel, and the hood hinge is attached to the body. And a hinge mail (5) attached to the inner panel (2b), the hinge mail (4) is coupled to the body, the hinge mail (5) is coupled to the inner panel, and the hinge mail is coupled. (4) and the female hinge (5) by pivotally supported pin (10) mounted for opening and closing the front hood body to the body, the front hood electrodeposition solution or the like in the coating process a hole for venting from the body is provided in the vicinity of coupling portion between the female hinge of the inner panel (5), the vehicle rear side the pin (10) from the front hood body Provided by breaking the front hood body, as described above the female hinge (5) and the body do not interfere, with the one end of the hinge center (S) side of the female hinge (5) is curved downwards In the front hood hinge structure in which the curved portion 13 is formed, the curved portion separated from the inner panel of the hinge frame (5) in the hood hinge at the position of the hole for removing the electrodeposition liquid or the like from the inside of the front hood body. The drain part for discharging | emitting said electrodeposition liquid etc. is provided by arrange | positioning the edge part of (13) and providing the bulge part to the downward direction at the edge part of the said curved part (13).
Further, the present invention lies in that the drain passage for extracting the electrodeposition liquid and the like from the front hood main body is inclined so that the electrodeposition liquid and the like are discharged.

DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of a hood hinge structure according to the present invention will be described with reference to the drawings. As shown in FIG. 1, in one embodiment of the present invention, a front opening type front hood 2 (hood main body) is mounted on a body 1 by a pair of left and right hood hinges 3, 3 ′. 2 to 6 show the hood hinge 3 (provided on the left side of the vehicle), and FIGS. 8 to 9 show the hood hinge 3 ′ (provided on the right side of the vehicle). 3 'are symmetrically configured and have substantially the same structure.
As shown in FIG. 2, the front hood 2 is formed by combining an outer panel 2a and an inner panel 2b. The present invention can also be applied to a rear-opening type, and can also be applied to other hoods such as a trunk hood (trunk lid) in addition to the front hood.
[0006]
As shown in FIG. 2, the hood hinge 3 includes a hinge male 4 attached to the body 1 and a hinge female 5 attached to the inner panel 2 b of the front hood 2. The hinge mail 4 rotatably supports the hinge mail 5. The hinge mail 4 is screwed to the body 1 portions on both sides of the engine room with bolts 6 and nuts 7, and the hinge mail 5 is screwed to the back surface of the front hood 2, that is, the inner panel 2 b with bolts 8 and nuts 9. . A hinge mail 4 and a hinge mail 5 are pivotally supported by a pin 10 so as to be rotatable. The hinge center S portion provided with the pin 10 is located on the lower surface side of the ventilator garnish 11 of the body 1. The ventilator garnish 11 is disposed below the front windshield 12.
[0007]
As shown in FIGS. 7 to 8, the hinge mail 4 is composed of a fixed portion 4a provided with two mounting holes 21 and a rising portion 4b which is erected by bending substantially perpendicularly from the end surface of the fixed portion 4a. The fixing portion 4a is attached to the panel 22 portion on the body 1 side by screwing with the bolt 6 and the nut 7 through the attachment hole 21 (see FIG. 2). On the other hand, the rising portion 4b is provided with a hole through which the pin 10 is inserted at the rear end portion.
[0008]
As shown in FIGS. 7 to 8, the hinge female 5 has an L-shaped cross section including a reference surface 5a along the reference surface on the front hood 2 (see FIG. 2) side and a rising portion 5b along the hinge mail 4. The plate is curved in a dog-leg manner. That is, as shown in FIG. 7, the hinge female 5 has one end on the hinge center S side curved downward to form a curved portion 13, and the other end fixed to the linear arm portion 14. Forming. Two fixing holes 15 for fixing are formed in the reference surface 5a of the arm portion.
As shown in FIG. 4, a hood hinge reinforcement 16 and a nut 9 are welded in advance to the inner surface side of the inner panel 2 b of the front hood 2. The arm portion 14 (see FIG. 7) is assembled to the nut 9 via the mounting hole 15 (see FIG. 7), and the bolt 8 is screwed into the nut 9 and tightened. As shown in FIG. Is fixed to the inner panel 2b.
[0009]
As shown in FIG. 3 or FIG. 4, drain holes 17 and 17 are provided in a portion of the inner panel 2b to which the hinge mail 5 is fixed, that is, both rear corners of the inner panel 2b. Each drain hole 17 is covered with an arm portion 14 (see FIG. 7) of the hinge mail 5.
On the other hand, as shown in FIG. 3, FIG. 4, or FIG. The bulging portion 18 is located at a position corresponding to the position of the drain hole 17 provided in the inner panel 2 b, and is provided in a bent portion 19 that is separated from the inner panel 2 b of the hinge mail 5. The bulging portion 18 has a bead shape that is recessed toward the side away from the inner panel 2b. As shown in FIG. 4, a drain passage 20 is formed between the hinge frame 5 and the inner panel 2b. The drain passage 20 is inclined so that the liquid flows naturally by the action of gravity in the electrodeposition coating process, and the inclination is not only when the front hood 2 is closed but also when it is opened. The liquid flows.
As shown in FIG. 3 or FIG. 4, the drain hole 17 is for draining the electrolytic solution or the like accumulated on the upper surface of the inner panel 2 b, and the electrolytic solution or the like is halfway through the drain passage 20 through the drain passage 20. It flows down into the engine room without stopping. Further, when the drain passage 20 has a width wider than the hole diameter of the drain hole 17, the discharge of the electrolytic solution or the like is performed more efficiently.
Thus, the layout of the hood hinge 3 can be performed without being affected by the position of the drain hole 17. Further, since the bulging portion 18 is provided in the bent portion 19 whose shape changes from a portion where the hood hinge 3 abuts against the inner panel 2b to a portion where the hood hinge 3 does not abut, the strength and rigidity of the hinge mail 5 is increased by the bulging portion 18. The hinge can be reduced in size and weight.
