DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge structure for a vehicle for rotatably supporting an opening / closing member such as a door, a hood, a gate, and a trunk lid provided at an opening of a vehicle such as an automobile.

[0002]

2. Description of the Related Art Opening and closing members such as doors, hoods, gates, and trunk lids are provided at openings of vehicles such as automobiles, and these opening and closing members are rotatably supported by hinges. Such a vehicle hinge includes a hinge member fixed to the vehicle side, a hinge member fixed to the opening / closing member side, and a hinge pin that rotatably couples both hinge members to each other. is there.

FIGS. 4 and 5 show such a conventional vehicle hinge structure. As shown in FIGS. 4 and 5, the vehicle hinge is a first hinge member fixed to the vehicle. And a mail as a second hinge member fixed to the opening / closing member side.
e) 2 and a hinge pin 3 for rotatably connecting the female (first hinge member) 1 and the mail (second hinge member) 2 to each other.

The female 1 has a base portion 11 and upright portions 12A and 12B formed on both sides of the base portion 11. Bolt holes for mounting bolts to be connected to a vehicle body (not shown) are formed in the base portion 11. 13a, 13b and 13c are formed, and pin holes 14a and 14b are formed in the upright portions 12A and 12B, respectively. Also, Mail 2
Are base portions 21A and 21B provided on both end sides, and standing portions 2 formed between these base portions 21A and 21B.
2A and 22B, and the upright portions 22A and 22B are connected via an intermediate portion 22C. Bolt holes 23a and 23b are formed in the base portions 21A and 21B for mounting bolts to be connected to the opening / closing member side (not shown), and pin holes 24 are formed in both the standing portions 22A and 22B.
a and 24b are formed.

[0005] The standing portions 22A, 22B of the mail 2
Are arranged so as to be interposed between the standing portions 12A, 12B of the female 1 and the bush 4 is interposed between the standing portions 12A, 12B of the female 1 and the standing portions 22A, 22B of the mail 2. The axial centers of the pin holes 14a, 24a, 24b, 14b and the holes of the bush 4 are aligned with each other.
The hinge for the vehicle is assembled by fitting the hinge pin 3 into the a, 24a, 24b, 14b and the bush 4 and then caulking the tip of the hinge pin 3.

That is, as shown in FIG. 5, the hinge pin 3 has a cylindrical shaft portion 31 and a head portion 32 whose diameter is larger than that of the shaft portion 31. In this example, the pin holes 14a, 24 are provided.
a, 31b of the hinge pin 3 from above, 24b, 14b
Is inserted and the tip portion 33 of the hinge pin 3 protruding from the lowermost pin hole 24b is swaged, so that the tip portion 33 is enlarged in diameter. The both standing portions 12A and 12B are sandwiched.

The caulking of the tip 33 prevents the hinge pin 3 from coming off the pin holes 14a, 24a, 24b, 14b and eliminates the looseness of the hinge pin 3. There is an important role of managing the rotational torque of the opening / closing member (operating torque required when rotating the opening / closing member around the hinge pin 3).

That is, in order to open and close the opening / closing member, the opening / closing member is rotated around the hinge pin 3.
At this time, the required operating torque (that is, the rotational torque of the opening / closing member) is slid at each contact portion in the three elements of the female (first hinge member) 1, the mail (second hinge member) 2, and the hinge pin 3. It depends on the frictional force generated when moving.

If the rotation torque of the opening / closing member is too large, a large operation force is required for opening / closing the opening / closing member, which burdens the operator or causes abnormal noise at the hinge portion. . Conversely, if the rotation torque of the opening / closing member is too small, the opening / closing member is easily rotated with a small force, for example, which may cause a problem at the time of manufacturing a vehicle, or may cause abnormal noise at a hinge portion. Is not preferred.

That is, when attaching the opening / closing member to the vehicle body, the operator holds the opening / closing member with the mail 2 attached thereto in advance and positions it at a required position of the opening of the vehicle body, and then moves the female 1 to the vehicle body. There is a procedure of fixing to the side, but at this time, if the female 1 and the female 2 rotate easily, the female 1 cannot maintain a predetermined angle with respect to the opening and closing member, and after positioning the opening and closing member, In addition, it is necessary to adjust the female 1 so that the female 1 is positioned at a predetermined posture with respect to the mounting position of the vehicle body, which greatly increases the number of mounting operations.

After the opening and closing member is attached to the vehicle body,
When attaching parts to the opening / closing member itself or attaching parts to the inside of the vehicle body from the opening of the vehicle body, etc.
If the mail 2 and the mail 2 are easily rotated, the opening and closing member may be rotated by a slight external force, which may hinder the operation, and greatly increases the number of operation steps. In particular, in a production line, vibrations from the line are applied to the vehicle body, so that the opening / closing member is easily rotated, which tends to hinder work.

In other words, if the rotation torque of the opening / closing member is ensured so that the female 1 and the mail 2 can maintain a predetermined opening degree, the positioning of the opening / closing member only needs to be performed. The female 1 can be set so as to be positioned at a predetermined position at the mounting position of the vehicle body, and mounting workability can be greatly improved. Also, after the opening / closing member is attached to the vehicle body, when the opening / closing member itself or the operation of attaching parts to the inside of the vehicle body is performed, the female 1 and the mail 2 are kept in a predetermined opening degree state. If it is held, the work can be performed easily.

Therefore, it is extremely important to adjust the rotational torque of the opening / closing member within a required range. The rotation torque of such an opening and closing member depends on the magnitude of the frictional force acting upon the relative rotation between the female 1 and the mail 2 and the like, but depends on the frictional force acting between the female 1 and the mail 2. In addition to the frictional force acting directly between the female 1 and the mail 2 via the bush 4, the frictional force acting between the female 1 and the hinge pin 3 and the frictional force acting between the female 2 and the hinge pin 3 There is a frictional force acting on

In the conventional vehicle hinge structure, for example, the tip (ie, caulking portion) 33 of the hinge pin 3 and the head 32
Thus, if compressive force is applied to both standing portions 12A, 12B of the female 1, the standing portions 12A, 12B are deformed so as to approach each other, and the respective standing portions 12A, 12B of the female 1 are mailed. 2 standing parts 22A, 22B
Press against the side. Thus, when the female 1 and the mail 2 rotate relative to each other, the standing portions 12A and 12A of the female 1
Through the bush 4 interposed between B and the upright portions 22A and 22B of the mail 2, the frictional resistance for suppressing the relative rotation between the female 1 and the mail 2 increases.

Therefore, in the conventional vehicle hinge structure, the rotational torque of the opening / closing member is controlled within a required range by adjusting the strength of the caulking and by appropriately selecting the type (material, thickness, etc.) of the bush 4. Has been adjusted.

[0016]

By the way, in the above-mentioned conventional hinge structure for a vehicle, when the strength of the crimping at the tip of the hinge pin 3 is adjusted, the female 1 and the mail 2 are adjusted.
Not only is the direct frictional force acting via the bush 4 between the hinge pin 3 but the front end (caulking portion) 33 of the hinge pin 3 and the head 32 directly contact the female 1, so that the hinge pin 3 The frictional force acting between the film 1 and the female 1 is also adjusted.

As described above, the magnitude of the rotation torque of the opening / closing member depends not only on the frictional force acting directly between the female 1 and the mail 2 (through the bush 4) but also on the hinge pin 3. When the opening and closing member is opened and closed, the hinge pin 3
It depends on which side of the mail 2 and the mail 2 together.

That is, when the opening and closing member is opened and closed, the mail 2 rotates together with the opening and closing member. At this time, the hinge pin 3 rotates integrally with the mail 2 or the hinge pin 3 is integrated with the female body 1 on the vehicle body side. The rotational torque of the opening / closing member changes depending on whether the state is fixed. Therefore, when the strength of the caulking at the tip of the hinge pin 3 is adjusted, the frictional force acting between the female 1 and the mail 2 and the frictional force acting between the hinge pin 3 and the female 1 open and close. The rotational torque of the member will be adjusted.
To adjust the strength of caulking, actually, it is performed by input adjustment and stroke adjustment at the time of caulking, but even if these elements are delicately adjusted, the rotational torque of the opening and closing member easily fluctuates greatly, It is difficult to reliably adjust the rotational torque of the opening / closing member within an appropriate range, and the fact is that such crimping force is managed on a daily basis.

Japanese Patent Application Laid-Open No. H5-1578 discloses such a hinge structure for a vehicle. In this technique, an uneven portion (a serration portion) is provided on a hinge pin side, and a projection is provided on a hinge mail hole side. The hinge pin is snapped into the hinge mail hole, so that the hinge pin is fitted into the hinge mail hole side between the protrusions. However, when the hinge pin is attached, a tapping operation is required.In addition, if the tapping force is large, the hinge may be plastically deformed. There is a problem that it is difficult to set the driving force, for example, it becomes insufficient.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is possible to easily perform various settings such as assembling work itself and processing conditions at the time of assembling work while ensuring the rotational torque of the opening and closing member. It is an object of the present invention to provide a hinge structure for a vehicle, which can be adjusted within an appropriate range.

The female 1 has a base portion 11 and standing portions 12A and 12B which are bent to form a pair from both sides of the base portion 11. In the base part 11,
Bolt holes 13a, 13b, and 13c are formed, and the female 1 is coupled to the vehicle body by inserting mounting bolts (not shown) into these bolt holes 13a, 13b, and 13c and screwing to the vehicle body (not shown). It is made to let. Further, pin holes 14a and 14b are formed in the both standing portions 12A and 12B, respectively.

The mail 2 has base portions 21A and 21B provided at both ends and standing portions 22A and 22B bent between the base portions 21A and 21B. 22B is connected via an intermediate portion 22C. Bolt holes 23a and 23b are formed in the base portions 21A and 21B.
The mail 2 is connected to the vehicle body by inserting mounting bolts (not shown) into the 3a and 23b and screwing the bolts to the vehicle body (not shown). In addition, the two-sided portion 22
Pin holes 24a and 24b are formed in A and 22B, respectively.

The female 1 and the female 2 can be formed by pressing or bending a thick sheet metal. To assemble such a vehicle hinge structure, the upright portions 22A and 22B of the mail 2 are disposed so as to be interposed between the upright portions 12A and 12B of the female 1, and the upright portions 12A and 12B of the female 1 and the mail are arranged. 2 standing part 22A,
22B and the pin holes 14
a, 24a, 24b, 14b and the axis of the hole of the bush 4 are aligned with each other, and the respective pin holes 14a, 24a, 24b, 14
This is performed by fitting the hinge pin 3 into the b and the bush 4 and then caulking the tip of the hinge pin 3.

As shown in FIGS. 2 and 3, the hinge pin 3 has a cylindrical shaft portion 31 and a head portion 32 whose diameter is larger than the shaft portion 31. In this example, the pin hole 14 is provided.
a, 24a, 24b, 14b, the shaft portion 31 of the hinge pin 3 is inserted from above, and the tip portion 33 of the hinge pin 3 protruding from the lowermost pin hole 24b is swaged.
The diameter of the distal end portion 33 is increased, and the head 32 and the distal end portion (caulking portion) 33 are used to form both the standing portions 12A, 1A of the female 1.
2B is pinched.

The outer diameter of the shaft portion 31 of the hinge pin 3 is
The inner diameter of each pin hole 14a, 24a, 24b, 14b is set slightly smaller than the inner diameter. That is, the outer peripheral surface of the shaft portion 31 of the hinge pin 3 and the pin holes 14a, 24a, 24b, 1
The hinge pin 3 is inserted between the pin holes 14a,
Clearances are provided to allow insertion and removal with respect to 24a, 24b, and 14b.

By the way, in the present hinge structure for a vehicle, as shown in FIGS. 2 and 3, the head portion 32 of the hinge pin 3 is provided with the uneven portion 5 and one side of the female (first hinge member) 1 is provided. A rotation restricting shape portion 6 into which the concave-convex shape portion 5 can be fitted is formed on the standing portion 12A, and the rotation of the hinge pin 3 is restricted by the fitting between the concave-convex shape portion 5 and the rotation restricting shape portion 6. It has become so.

In the present embodiment, the uneven portions 5 are formed in a plurality of three-dimensionally formed radially at equal intervals so as to straddle the lower surface of the head portion 32 of the hinge pin 3 and the outer peripheral surface of the shaft portion 31 in contact therewith. The rotation regulating shape portion 6 is formed of a plurality of grooves into which the plurality of ribs can be fitted. Since the plurality of ribs and the plurality of grooves are formed at regular intervals, a slight rotation of the hinge pin 3 (within an angle corresponding to the arrangement interval of the ribs and the grooves) allows the uneven portion 5 to be formed.
Can be fitted to the rotation restricting shape part 6.

The shaft 31 of the hinge pin 3 and the pin hole 1 are also provided between the concavo-convex shape portion 5 and the rotation regulating shape portion 6.
Similarly to the gaps between 4a, 24a, 24b, and 14b, a clearance is provided so that the concavo-convex shape portion 5 can be inserted into and removed from the rotation regulating shape portion 6. Since the vehicle hinge structure as one embodiment of the present invention is configured as described above, in assembling the vehicle hinge, first,
The upright portions 22A, 22B of the mail 2 are arranged between the upright portions 12A, 12B of the female 1, and the bush 4 is provided between the upright portions 12A, 12B of the female 1 and the upright portions 22A, 22B of the mail 2. Intervene. And each pin hole 14a,
The pin holes 14a, 24a, 24b, 14b are aligned with the axes of the holes of the bush 4 and the pin holes 14a, 24a, 24b, 14b.
Then, the hinge pin 3 is fitted into the bush 4. At this time,
The concave-convex shape portion 5 is fitted to the rotation regulating shape portion 6. Then, the tip portion 33 of the hinge pin 3 is caulked.

As described above, the crimping force at the time of crimping the distal end portion 33 is set so that the rotation torque of the opening / closing member (operating torque required for rotating the opening / closing member around the hinge pin 3) is within a predetermined range. Is set. Therefore, by crimping the distal end portion 33 of the hinge pin 3, the hinge pin 3 is prevented from being detached from the pin holes 14a, 24a, 24b, 14b, the backlash of the hinge pin 3 is eliminated, and the opening / closing member of the hinge pin 3 is opened. The rotation torque will be adjusted to be appropriate.

In the present hinge structure for a vehicle, the fitting between the concave-convex shape portion 5 and the rotation regulating shape portion 6 is always maintained by merely applying a caulking force to such an extent that the hinge pin 3 is prevented from coming off and rattling does not occur. When the opening / closing member is rotated, the hinge pin 3 behaves integrally with the female 1, and when a caulking force of a greater magnitude is applied, the hinge pin 3 is directly moved between the female 1 and the female 2 (the Only the acting friction force (via 4) will be adjusted.

Accordingly, the setting of the caulking force is to adjust the direct frictional force between the female 1 and the mail 2, which is one of the adjustment factors of the rotational torque of the opening / closing member, and the opening / closing member for the caulking force is adjusted. The fluctuation of the rotational torque becomes simple and stable. This makes it easy to set the crimping force for setting the rotation torque of the opening / closing member to a predetermined state. Conversely, if an appropriate caulking force is set, the rotation torque of the opening / closing member can be stabilized. You can get it.

That is, in the conventional structure (see FIGS. 4 and 5), when the opening and closing member is opened and closed, the hinge pin 3
Which side of the mail 1 and the mail 2 are to be rotated together depends on the caulking force, so if the caulking force is adjusted to adjust, the friction force acting between the female 1 and the mail 2 and the hinge pin 3 The rotational torque of the opening / closing member is adjusted from both sides of the frictional force acting between the opening and closing member and the female member 1. It is difficult to make the rotational torque of the opening / closing member appropriate even if the caulking force is finely adjusted. there were.

On the other hand, in the present hinge structure for a vehicle,
The hinge pin 3 and the female 1 are integrally formed from the beginning, and if the caulking force is adjusted, only the frictional force acting between the female 1 and the female 2 is adjusted. For this reason, the correspondence between the caulking force and the rotation torque of the opening / closing member becomes stable, the rotation torque of the opening / closing member can be adjusted extremely simply, the setting of the caulking force becomes easy, and If the caulking force is set appropriately, the rotational torque of the opening / closing member can be surely adjusted to an appropriate range.

In this embodiment, the outer peripheral surface of the shaft portion 31 of the hinge pin 3 and the pin holes 14a, 24a, 24b, 14
b, the hinge pin 3 is inserted between the pin holes 14a, 14a and 2b.
4a, 24b, and 14b are provided with clearances that allow insertion / removal thereof. Further, between the concave-convex portion 5 and the rotation-restricting shape portion 6, the concave-convex-shaped portion 5 is provided with respect to the rotation restricting shape portion 6. Since the clearance is provided to enable the insertion and removal, the pin holes 14a and 24 of the hinge pin 3 are provided.
It is possible to easily insert and extract the a, 24b, and 14b without applying any load to the female 1 and the female 2, and there is also an advantage that workability is good.

Further, since the plurality of ribs forming the uneven portion 5 and the plurality of grooves forming the rotation restricting portion 6 are formed at equal intervals, the hinge pin 3 is slightly (namely, rib). By simply rotating (within the angle of the arrangement interval of the grooves and the grooves), the concave-convex shape portion 5 can be fitted to the rotation regulating shape portion 6, and in this respect, there is an advantage that the workability is good.

Further, the fitting of the uneven portion 5 to the rotation regulating portion 6 can be performed only by a simple phase adjustment of the two, and the tapping operation as in the prior art disclosed in Japanese Utility Model Publication No. 5-1578 is not possible. This is unnecessary, and not only can the work load be reduced, but also the risk of plastic deformation of the hinge due to tapping can be avoided. Furthermore, in the present embodiment, since the uneven portion 5 is formed on the head 32 of the hinge pin 3, there is also an advantage in manufacturing such that the uneven portion 5 can be easily integrally formed at the time of manufacturing the hinge pin 3. This contributes to reducing manufacturing costs.

Of course, the location of the uneven portion 5 is not limited to the head 32 of the hinge pin 3, but rather the tip 33 of the hinge pin 3, or the outer periphery of the shaft 31 close to the head 32 or the tip 33. May be formed. Furthermore, the shapes of the concavo-convex shape portion 5 and the rotation restricting shape portion 6 may be any shapes as long as they can fit together to restrict the rotation of the hinge pin 3, and are not limited at all. In addition, when the concave-convex shape portion 5 is configured by a plurality of ribs as in the present embodiment,
If the number of ribs is increased (naturally, the number of grooves on the rotation restricting shape portion 6 is increased according to the number of ribs), the fitting of the uneven portion 5 to the rotation restricting shape portion 6 is further facilitated.

In the present embodiment, the female 1 is mounted on the vehicle body and the mail 2 is mounted on the opening / closing member. Conversely, the female 1 is mounted on the opening / closing member, and the mail 2 is mounted on the vehicle body. Each side may be attached. Further, in the present embodiment, the rotation restricting shape portion 6 is provided on the first hinge member 1 side fixed to the vehicle side, but the rotation restricting shape portion 6 is provided on the second hinge member 2 side fixed on the opening / closing member side. May be provided to restrict the rotation so that the hinge pin 3 rotates integrally with the second hinge member 2.

In this embodiment, the standing portions 12A and 12B of the female 1 and the standing portions 22A and 22B of the mail 2 are provided.
Although the bush 4 is interposed between the bush and the component, a component configuration that does not use the bush 4 may be adopted.

[0045]

As described in detail above, according to the hinge structure for a vehicle according to the first aspect of the present invention, the uneven portion provided on the hinge pin and any one of the first hinge member and the second hinge member are provided. Since the rotation of the hinge pin is restricted by fitting with the rotation restricting shape formed on one side, the hinge pin behaves integrally with the first hinge member or the second hinge member when the opening / closing member rotates. As a result, it is possible to reduce a factor affecting the rotational torque of the opening / closing member. Therefore, without increasing costs,
Adjustment so that the rotational torque of the opening / closing member becomes appropriate can be performed more easily. That is, the rotation torque management of the opening / closing member can be further simplified.

According to the vehicle hinge structure of the present invention, the hinge pin can be easily mounted on the first hinge member and the second hinge member, and the assemblability of the hinge is improved. . According to the hinge structure for a vehicle according to the third aspect of the present invention, the uneven portion can be easily formed on the hinge pin, which contributes to cost reduction.
