Description

[Detailed explanation of the idea] The present invention relates to an automobile door hinge.

In recent years, due to vehicle design, the curvature of the door window glass 1 has been increasing, and as a result, especially the rear door 2
When a passenger gets on and off, that is, when the door 2 is opened, the door 2 rotates around a fixed hinge pin (not shown), so the hinge side of the door window glass 1 is opened in the door opening space 3. This creates an inconvenience in that the opening space 3 of the door becomes narrow when passengers get on and off the vehicle.

The present invention was proposed to solve the above-mentioned conventional drawbacks, and by using a cam and a long hole as a means for moving the rotation axis of the upper hinge, the hinge side of the door window glass remains open even when the door is opened. It is an object of the present invention to provide a door hinge device for an automobile that is free from the risk of digging into the interior of the vehicle from the opening space of the door.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 4 is an upper hinge, 5 is a lower hinge, and the lower hinge 5 is the fourth
In the drawings and FIG. 5, a ball joint is used to simplify the mechanism and reduce weight, but the same mechanism as the upper hinge 4 may be used for the lower hinge 5 instead.

In Figures 3 to 5, 6 is the first door hinge that constitutes the door hinge.
The mail 7 as a hinge member is a hinge member as a second hinge member, the mail 6 is fixed to the door 8 of the vehicle, and the hinge member 7 is fixed to the door 2.

A cam 9 is formed on the part of the female mail 7 facing the mail 6, and the mail 6 is formed on the cam surfaces 9a to 9b of the cam 9.
A pin 10 fixed to is engaged to regulate the rotational position of the female mail 7 with respect to the mail 6.

Reference numeral 11 denotes an intermediate member which is pivotally connected to the mail 6 by a pin 12 and has a long hole 13, and is located between the mail 6 and the mantle 1, and has a pin 14 on the opposite side of the long hole 13 facing the pin 12. It is also pivotally connected to Himeru 7.

The pin 10 passes through an elongated hole 13, and the intermediate member 11 can move along the pin 10 through the elongated hole 13, and the pin 10 and the cam surfaces 9a to 9b The spring force of a spring 15 stretched between the end of the member 11 opposite the pin 12 and the mail 6 keeps them in constant contact.

In this way, the female member 7 and the male member 6 are connected via the intermediate member 11.

The mail 6 and the mail 7 are formed in a U-shape, but this is done from the viewpoint of strength, and if they can withstand sufficient strength, they may be formed into a flat plate shape.

Recesses 16 a, 16 b, and 16 C for engaging the pin 10 and holding its position are formed in the cam surface of the cam 9 sequentially from the side closer to the door 2. The relationship between the cam surface 9a and the far side cam surface 9b with respect to the pin 14 is (distance from the pin 14 to the cam surface 9a) <
(distance from pin 14 to cam surface 9b).

17 is a pin hole for attaching mail 6 to pillar 8, 18
is a pin hole for attaching Himeru 7 to door 2.

The lower hinge 5 is attached to the mail 6a attached to the pillar 8 and the door 2.
The lower hinge 5 is connected to the upper hinge 4 by a ball 19 attached to the lower hinge 7a and a downward concave hole 21 formed in an arm 20 provided in the lower hinge 7. According to the movement of the ball 19, the ball 19 is tilted at an angle of inclination due to the movement of the ball 19.

Note that the positional relationship between the ball and the recessed hole may be upside down.

Next, to explain the operation, the solid line in FIG. 3 shows the door closed state, and the two-dot chain line shows the door open state.

Now, in FIG. 3, when the door 2 is pulled in the direction of the arrow in the opening direction, the armature 7 also rotates in the direction of the arrow using the pin 14 as a fulcrum.

In this case, the cam surfaces 9a to 9b of the female cam are constantly pressed against the pin 10 via the intermediate member 11 due to the spring force of the spring 15, so the rotating position of the female 7 is at the cam 9.
It will be regulated by the shape of.

In addition, the force transfer surfaces 9a to 9b have recesses 16a, 16b,
16C is formed, so pin 10 is formed as shown in the drawing.
When the recess 16a is engaged with the recess 16a, the door is kept in the closed state, but when the armature 7 rotates in the direction of the arrow, the recess i6b first engages with the pin 10, keeping the door in the half-open state. When the door 7 further rotates, the recess 16C engages with the pin 10 to maintain the door in its fully open state.

At this time, the intermediate member 11 is pulled in the same direction via the pin 14, so it rotates in the direction of the arrow with the pin 12 as a fulcrum against the spring force of the spring 15. While being guided by the pin 10, it rotates to the position 11', and the armature 7 is also at the position 7', and when the door is open, the armature 7', the intermediate member 11', and the pin 14' are in the position shown by the two-dot chain line. becomes.

In this case, the cam surfaces 9a to 9b of the cam 9 are shaped so that the distance between the cam surface 9b and the pin 14 is larger than the distance between the cam surface 9a and the pin 14, so that when fully opened, The distance between the position 14' of the pin 14 and the pin 10 is larger than the distance between the pin 14 and the pin 10 in the fully closed state in proportion to the extent to which the shape of the cam surface expands outward. As a result, the door 2 moves further downward in FIG. 3, ie, the opening space of the door becomes larger.

In this case, the lower hinge 5 is tilted via the ball 19 according to the movement of the upper hinge 4, and the door 2 is in the state shown in FIG.

Note that the shape of the cam 9 is a recessed portion 16a. 16 b, 18
However, the shape of the cam surface is not limited to this, and the shape of the cam surface increases as the distance from the pivot point with the intermediate member increases as the distance from the door attachment part of the Himeru increases. Any other curved surface may be used as long as it is configured so as to.

As explained in detail above, the present invention is based on the first
The second part is always in contact with the pin member attached to the hinge member.
The shape of the cam surface of the hinge member (door side) increases as the distance from the pivot point between the intermediate member pivotally connected to the first hinge member and the second hinge member becomes farther from the door attachment portion of the second hinge member. Therefore, when the door is opened, the second hinge member fixed to the door moves to the side to expand the opening space of the door according to the shape of the cam surface. Open the opening space wide,
Even if the door window glass has a curved shape, it is possible to eliminate the inconvenience that it gets stuck in the space and obstructs getting on and off the vehicle.

Although this embodiment discloses a configuration in which the first hinge member is a mail and the second hinge member is a mail, there is no functional difference even if the first hinge member is changed to a mail and the second hinge member is changed to a mail. There is no problem.
