As shown in FIG. 13, the hinge bracket 110 includes a base plate portion 111 that is fixed to an apron upper member 200 that is a skeleton member at the front of the vehicle body, and a vertical wall portion 112 that rises upward from an end portion of the base plate portion 111. , Is formed from. As shown in FIG. 14, a hole 113 is formed in the vertical wall portion 112, and the hinge arm 120 is pivotally supported in the hole 113 via a pin 150 (FIG. 12). In this way, the tip end side of the hinge arm 120 that is rotatable with respect to the hinge bracket 110 is fixed to the back surface of the hood 300 as shown in FIG. The apron upper member 200 includes an upper surface 201 to which the hinge bracket 110 is attached. The upper surface 201 is formed flat, for example.
As shown in FIG. 14, the base plate portion 111 of the hinge bracket 110 has bolt insertion holes (not shown) at a location A <b> 1 and a location A <b> 2 at a position shifted backward from the location A <b> 1. Corresponding to these holes, there are bolt insertion holes (not shown) in the apron upper member 200 and nuts welded corresponding to these holes, and bolts are passed through these holes and screwed into the nuts. Thus, the base plate part 111 is fixed to the apron upper member 200.

  A front fender panel 400 is disposed on a side surface of the front portion of the vehicle body. A conventional front fender panel 400 shown in FIG. 15 has a vertical wall-shaped apron portion 410 that forms the design surface of the vehicle body outer surface area excluding the front wheel area, and projects from the upper end portion of the apron section 410 to the engine room side. The flange portion 420 is provided. The front fender panel 400 is attached to the hinge bracket 110 fixed to the apron upper member 200. Specifically, as shown in FIGS. 14 and 15, the flange portion 420 of the front fender panel 400 is located on the vertical wall portion 112 of the hinge bracket 110 at a position shifted from the hinge arm mounting hole 113 toward the vehicle rear side. A mounting portion 114 is provided for attaching the. As shown in FIG. 13, the attachment portion 114 extends in the horizontal direction from the upper edge of the vertical wall portion 112 so as to extend in parallel with the base plate portion 111, and the upper surface thereof is formed as a flat attachment surface 114A. Bolt insertion holes (not shown) are formed in the mounting surface 114A and the flange portion 420, and bolts (not shown) passed therethrough are screwed to nuts (not shown) welded to the mounting surface 114A.

  Patent Document 1 discloses a hood hinge structure for attaching the hood and the front fender panel to the vehicle body so as to improve the mountability between the hood and the front fender panel. In the hood hinge of Patent Document 1, the hood 300 is supported by the hinge arm and the front fender panel 400 is supported by the hinge bracket 110, similarly to the conventional hood hinge 100 shown in FIG.

JP 2001-278121 A

Conventionally, even if the hood hinge 110 that supports the hood 300 and the front fender panel 400 is fixed at a predetermined body mounting position so that the hood 300 and the front fender panel 400 are disposed at a desired mounting position, the vehicle body itself is inclined. In this case, for example, the accuracy of the body deviates from the design value, resulting in variations in installation. A solid line in FIG. 14 indicates a temporary ideal state determined by design, and a two-dot broken line indicates a state in which the upper surface 201 of the apron upper member 200 is inclined based on a difference in lever ratio. For example, when the apron upper member 200 is rotated at an angle θ (1.1 °) about the front mounting location A1 of the hinge bracket 110 and the apron upper member rear side is raised, the position of the hinge arm mounting hole 113 is Moves 0.69 mm (Y ₁ ) upward, 1.31 mm (X ₁ ) forward, and the position of the mounting surface 114A of the fender is 1.48 mm (Y ₂ ) upward and 1.52 mm (X ₂ ) forward. Moving. With such movement of the hinge arm mounting hole 113 and the fender mounting surface 114A, a step between the hood 300 and the fender panel 400 occurs, for example, 0.79 mm (= 1.48-0.69). In order to ensure high designability in the vehicle, it is desirable that such an installation error be close to 0, but the conventional hinge bracket 110 is greatly affected by the lever ratio.

  The present invention was created in view of the above points, and an object of the present invention is to provide a hood hinge that can reduce the error as compared with a conventional hinge bracket even when the body accuracy deviates from the design value. .

In order to achieve the above object, the present invention is a hood hinge comprising a hinge bracket fixed to an apron upper member, which is a skeleton member of a vehicle body, and a hinge arm rotatably attached to the hinge bracket. The hinge bracket includes a pair of first mounting portions provided at a distance from each other so as to be fixed to the mounting surface of the apron upper member , a second mounting portion to which the front fender panel is mounted, and a hinge arm. attaching a third attachment portion includes a third attachment portion is provided in an intermediate position location of the one first mounting portion of the first mounting portion of the other, the vertical position of the apron upper members of the pair It is set to 1/2 or less of the space | interval of a 1st attachment part, and the 2nd attachment part is provided above the 3rd attachment part, It is characterized by the above-mentioned.
In the hood hinge of the present invention, the second mounting portion has a hole for inserting a bolt, and this hole is formed larger than the thickness of the screw portion of the bolt.

  ADVANTAGE OF THE INVENTION According to this invention, the installation error by the variation in a body can be reduced. In particular, the third mounting portion for mounting the hinge arm and the second mounting portion for mounting the fender are placed close to each other, and they are arranged side by side in the vertical direction. Thus, the difference in relative movement distance can be reduced as compared with the prior art.

The first mounting portions 21F and 21R are fixed to the base 210 with bolts 81 and nuts 82 as shown in FIG. In the present embodiment, the pedestal 210 is one element constituting the apron upper member 200. Such a pedestal 210 may be formed integrally with the outer panel when the apron upper member 200 is configured as a closed cross-sectional structure by joining an outer panel and an inner panel, for example.

  A second attachment portion 22 is provided on the upper edge portion 23G of the upper wall portion 23U. Specifically, as shown in FIG. 3, the second mounting portion 22 is provided so as to extend from the upper edge portion 23 </ b> G of the connecting portion 23 in a direction that is bent in an L shape. The second attachment portion 22 has an upper surface 22U and a lower surface. The upper surface 22U of the second mounting portion 22 is formed in parallel with the upper surfaces 21U of the front and rear first mounting portions 21F and 21R. Bolt insertion hole 22H is formed in the 2nd attaching part 22, and the nut is welded to the lower surface.

  The front fender panel 400 is fixed to the second attachment portion 22. As shown in FIG. 2, the front fender panel 400 includes an apron portion 410 that forms a design surface of the vehicle body outer surface area excluding the front wheel area, and a flange that hangs down from the upper end of the apron section 410 and protrudes toward the engine room side Part 420. The flange portion 420 is formed flat as an attachment surface, and an opening (not shown) corresponding to the hole 22H of the second attachment portion 22 is formed. As shown in FIG. 2, the flange portion 420 is fixed to the second mounting portion 22 with bolts 81 and nuts 82.

  Further, as shown in FIG. 4, the connecting portion 23 of the present embodiment is at the same height as the front and rear first mounting portions 21 </ b> F and 21 </ b> R, and is further below the second mounting portion 22. Has a hole 23H. Specifically, if the hole 23H is an intermediate position α (see FIG. 3) of an imaginary line L1 connecting one first mounting portion 21F and the other first mounting portion 21R, the hole 23H further passes through the intermediate position α. It is provided on a virtual horizontal line L2 (see FIG. 3) orthogonal to the virtual line L1. The second attachment portion 22 is on a virtual line L3 that passes through the intermediate position α and is orthogonal to the virtual line L1 and the virtual horizontal line L2. That is, it is provided at a position higher than the intermediate position α, that is, a position higher than the first attachment portions 21F and 21R.

The hole 23H is used for attaching the hinge arm 30.
As shown in FIG. 2, a pin 150, which is a rotation shaft attached to the proximal end portion of the hinge arm 30, is supported by the hole 23 </ b> H of the hinge bracket 20, and the hinge arm 30 is rotatably supported by the hinge bracket 20. . The distal end side of the hinge arm 30 is fixed to the back surface of the hood 300 as shown in FIG.

  3 and 4, the protrusion 23G protruding from the surface of the connecting portion 23 to the engine room side rotates the hinge arm 30 supported at one end thereof in the hole 23H so that the hood 300 is over-opened. It has a function to prevent. During the rotation of the hinge arm 30, the hinge arm 30 abuts against the convex portion 23G, so that the opening operation of the hood 300 is restricted.

  In such a hood hinge structure 1, the hood hinge 10 supports the hood 300 with the hinge arm 30 and the hinge bracket 20, and supports the front fender panel 400 with the hinge bracket 20.

  The hood 300 and the front fender panel 400 are minimized so that the parting gap C (see FIG. 2) between the hood 300 and the front fender panel 400 is minimized and no step is generated between the hood 300 and the front fender panel 400. Further, the mounting position of the hood hinge 10 that supports the hood 300 and the front fender panel 400, particularly the hinge bracket 20, to the body is selected.

When such a hood hinge structure 1 is set in a vehicle, when the apron upper member 200 to which the hinge bracket 20 is attached deviates from the designed position, for example, when the rear side deviates from the designed position so as to rise 1.0 mm upward. However, the hinge bracket 20 is provided with a hole 23H, which is the rotation center of the hinge arm 30, at an intermediate position between the front and rear first mounting portions 21F, 21R, and a second mounting portion 22, which is a fender mounting surface, above the hole 23H. Therefore, it is possible to reduce the amount of positional deviation between the hole 23H that supports the hood 300 and the second attachment portion 22 that supports the fender panel 400. Specifically, the hinge bracket 20 of the present embodiment (a) brings the hole 23H that supports the hood 300 and the second attachment portion 22 that supports the fender panel 400 close to each other, and (b) the hole 23H and the second attachment. Since the portion 22 and the second mounting portion 22 are provided in the middle region of the hinge bracket 20 in the front-rear direction, the portion 22 and the second mounting portion 22 are provided side by side in the vertical direction. The amount of deviation between the positions of the hole 23H and the second attachment portion 22, particularly the amount of deviation in the vehicle vertical direction can be made the same or similar. Further, the amount of positional deviation before and after the hole 23H supporting the hinge arm 30 can be made substantially zero.
It can be confirmed in the following experimental example that the hinge bracket 20 of the present embodiment is less affected by the variation in the body.

[Experiment 1]
The influence of the installation error between the conventional hinge bracket 110 (see FIG. 12) and the hinge bracket 20 of the present embodiment, that is, the body variation of the apron upper member 200 to which the hinge is attached was evaluated.
FIG. 5A shows a conventional hinge bracket 110, and FIG. 5B shows the hinge bracket 20 of the present embodiment. A broken line in each figure indicates a normal position, and a solid line indicates a state of attachment when the attachment surface is inclined rearward and upward. The center of rotation of the mounting surface was the front mounting hole position for fixing the hinge brackets 110 and 20 to the mounting surface. With the front hole position as the origin, a line extending rearward of the vehicle is defined as an X axis, and a line extending upward is defined as a Y axis. In this experiment, it is assumed that the mounting surface is rotated around the center of rotation by an angle of 1.15 °.
5A and 5B, the positions (XY coordinates) of the hinge arms mounting holes 113 and 23H before and after the rotation of the hinge brackets 110 and 20 and the mounting portions 114 and 22 of the front fender panel 400. The position (XY coordinates) is shown in Table 1 below.

In addition, the seating surface exact size A of this embodiment of Table 1 fixes the bolt insertion hole 21H and the rear first mounting portion 21R, which are locations where the front first mounting portion 21F is fixed to the vehicle body, to the vehicle body. The space | interval with the bolt insertion hole 21H which is a location is shown. Hereinafter, in the present embodiment, this interval is referred to as “the interval between the pair of first attachment portions 21F and 21R”.

As shown in Table 1, in the conventional hinge bracket 110, the position of the hinge arm mounting hole 113 moves 0.69 mm upward and 1.31 mm forward, and the position of the mounting portion 114 of the fender is 1 upward. .48mm, moved forward 1.52mm. With the movement of the hinge arm mounting hole 113 and the mounting portion 114 of the fender 400, a step between the hood panel and the fender panel is, for example, 0.79 mm (= 1.48-0.69).
On the other hand, in the hinge bracket 20 of the present embodiment, the position of the hinge arm mounting hole 23H moves 0.50 mm upward and 0.01 mm forward, and the position of the second mounting portion 22 of the fender panel 400 is It moved 0.50 mm upward and 0.31 mm forward. Even with the movement of the hinge arm mounting hole 23H and the fender mounting second mounting portion 22, it was possible to prevent the step between the hood panel and the fender panel. This is because, in this embodiment, the hinge arm mounting hole 23H and the fender mounting second mounting portion 22 are placed close to each other, and they are arranged side by side in the vertical direction. Are based on the fact that the difference in relative movement distance can be 0 (= 0.50-0.50).
Thus, compared with the conventional hinge bracket 110, the hinge bracket 20 according to the present embodiment is not affected by the body accuracy, and can prevent the occurrence of a step in the parting gap C based on the installation error.
Further, since the forward moving amount is as small as 0.01 mm, the influence on the parting gap between the cowl louver 500 shown in FIG. 12 and the headlamp 600 shown in FIG. 15 can be reduced. In FIGS. 12 and 15, the entire display of the cowl louver 500 and the headlamp 600 is omitted, and only a part of them is shown.

Hereinafter, another experimental example of the first embodiment will be described.
[Experiment 2]
FIG. 6 shows a seating surface exact size A (see FIG. 5) of the attachment portion to the body of 50.0 mm, a movement amount B as the body variation of 1.0 mm, and a movement angle as the body variation (angle display of B) C. It is a figure for demonstrating the variation | change_quantity of the up-down direction in the point (X, Y) in FIG. The X coordinate of the point is set to 5, 12.5, 15, 20, 25, 30, 35, 37.5, 45, 50, 55, 62.5, 65, 75, and the Y coordinate of the point is set to 0, 5 , 15, 25, 35, 45, 55, 65, 75.
When the hinge arm mounting hole 23H is set at a point (50, 0-75) having an X coordinate of 50 and a Y coordinate of 0 to 75, the value of L at each point having an X coordinate of 50, that is, Y The amount of movement in the direction was approximately 1.0.
When the second attachment portion 22 for attaching the fender is set to a point (37.5, 0 to 75) having an X coordinate of 37.5 and a Y coordinate of 0 to 75, each point having an X coordinate of 37.5 The value of L, i.e., the amount of movement in the Y direction was about 0.75.
When the second attachment part 22 for attaching the fender is set to a point (62.5, 0 to 75) having an X coordinate of 62.5 and a Y coordinate of 0 to 75, each point having an X coordinate of 62.5 The value of L, i.e., the amount of movement in the Y direction was about 1.25.
In this way, the difference between the X coordinate of the hinge arm mounting hole 23H as the third mounting portion and the X coordinate of the fender mounting second mounting portion 22 is 12.5 mm, that is, 1/1 of the seat surface exact size A. By setting it to 4 or less, the difference in the amount of upward movement can be made approximately 0.25 mm or less. Thereby, for example, 0.5 mm which is the dimension of the step between the hood 300 and the fender 400 at the parting gap, which is a desirable setting in the conventional vehicle, can be halved.

[Experiment 3]
The value of L at each point when the hinge arm mounting hole 23H is set at each coordinate in FIG. 6, that is, the amount of movement in the Y direction is approximately 0.4 mm at each point where the X coordinate is 20. It was. The amount of movement in the Y direction was about 0.5 mm at each point where the X coordinate was 25. The amount of movement in the Y direction was approximately 0.6 mm at each point where the X coordinate was 30.
As described above, the coordinates of the hinge arm mounting hole 23H are set to 20 to 30, that is, 2/5 to 3/5 of the seating surface exact size A, so that the upward movement amount is approximately 0. 0. It can be 6 mm or less. Thereby, it is possible to reduce the influence on the dimension considered to be desirable, that is, the parting step between the hood 300 and the cowl louver 500 (see FIG. 12).

[Experimental Example 4]
FIG. 7 shows that the seat surface exact size A (see FIG. 5) of the attachment portion to the body is 50.0 mm, the movement amount B as the body variation is 1.0 mm, and the movement angle (B angle display) C as the body variation. It is a figure for demonstrating the variation | change_quantity of the front-back direction in the point (X, Y) in FIG. The X coordinate of the point is set to 5, 12.5, 15, 20, 25, 30, 35, 37.5, 45, 50, 55, 62.5, 65, 75, and the Y coordinate of the point is set to 0, 5 , 15, 25, 35, 45, 55, 65, 75.
The value of K at each point when the hinge arm mounting hole 23H is set at each coordinate in FIG. 7, that is, the amount of movement in the X direction was substantially 0 at each point where the Y coordinate was 0. The amount of movement in the X direction was approximately −0.1 at each point where the Y coordinate was 5. That is, it moved about 0.1 forward. The amount of movement in the X direction was approximately −0.5 at each point where the Y coordinate was 25. That is, it moved almost 0.5 forward.
Thus, the coordinate of the hole 23H for attaching the hinge arm is such that the Y coordinate is 25, that is, 1/2 or less of the seating surface exact size A, so that the forward movement amount is approximately 0.5 mm or less. Can do. Thereby, the dimension considered to be desirable can be set, and the influence on the parting gap between the hood 300 and the cowl louver 500 or the headlamp 600 can be reduced.
