That is, in the former door hinge, although the opening of the door is large and a wide opening can be obtained, the hinge portion is exposed to the outside of the vehicle, which is unattractive and causes wind noise.

On the other hand, in the latter door hinge, the hinge portion is not exposed to the outside of the vehicle, but the back door and the vehicle body interfere with each other to reduce the opening degree.

The present invention has been made in view of the above-mentioned problems, and provides a vehicle door hinge capable of obtaining a wide opening while having a structure that looks good without the hinge member being exposed to the outside of the vehicle when the door is closed. It is intended to be provided.

(Means for Solving the Problems) In order to achieve the above-mentioned object, in the present invention,
One end of the hinge member 1 is centered on the vehicle body side shaft fulcrum 11,
The entire hinge member 1 is rotatably attached within a range from a hinge closed position arranged inside the company to a hinge open position arranged at the other end of the hinge member 1 on the door side shaft fulcrum 12 outside the vehicle. A door is rotatably attached to a door-side shaft fulcrum 12 of the member 1, and a link member 2 is rotatably attached to an intermediate portion of the hinge member 1 about a link rotation shaft 13. Between the vehicle body side pin 21 and the vehicle body side pin 21 and the vehicle body side guide groove 4 which guides the movement between the vehicle body side pin 21 and the vehicle body. Vehicle body side guide means for guiding the vehicle is provided, and between the other end of the link member 2 and the door,
Door-side guide means is provided which has a door-side pin 22 and a door-side guide groove 5 that engages with the door-side pin 22 and guides the movement thereof, and guides the movement of the other end of the link member with respect to the door. The vehicle body side guide groove 4 is used to rotate the hinge member 1 from the hinge closed position to the hinge open position when opening the door from the fully closed state to the half opened state.
11 is formed in an arc shape, and a stopper groove 41 for guiding one end of the link member 2 in a direction to approach the vehicle body side shaft fulcrum 11 is continuously formed at one end of the vehicle body side guide groove 4. The door-side guide groove 5 is formed in an arc shape around the door-side shaft fulcrum 12 so as to rotate the door from the half-open side to the fully-open direction around the door-side shaft fulcrum 12, and at the door side. At one end of the guide groove 5, the other end of the link member 2 is restricted from moving with respect to the door when the door is rotated from the fully closed state to the half open state, and the door is rotated from the half open state to the fully open side. A stopper groove 51 for guiding the other end of the link member 2 so as to rotate the link member 2 so as to move the vehicle body side pin 21 into the stopper groove 41 due to the movement.

At this time, in the vehicle body side guide means, since the vehicle body side pin 21 is arranged in the arcuate vehicle body side guide groove 4 centered on the vehicle body side shaft fulcrum 11, it moves along the vehicle body side guide groove 4, Along with this, the hinge member 1 rotates about the vehicle body side shaft fulcrum 11, and the door also rotates in the opening direction about the vehicle body side shaft fulcrum 11. At this time,
Since the outer groove 51 restricts the movement of the door pinn 22 in the door guide means, the rotation of the door about the door pivot 12 is restricted.

Then, when the vehicle outer side pin 21 moves to the end of the vehicle body side guide groove 4, the hinge member 1 centered on the vehicle body side shaft fulcrum 11 is formed.
The rotation of the door is restricted, and at this time, the door is opened to the half-opened state, the hinge member 1 is rotated to the hinge open position, and the door side shaft fulcrum 12 is moved to the vehicle exterior position.

When the door is further rotated in the opening direction, the rotation of the vehicle body side pin 21 around the vehicle body pivot 11 is restricted, so that the vehicle body side 21 moves along the stopper groove 41 and the link member. While one end of 2 moves toward the vehicle body side shaft fulcrum 11, the door side pin 22 moves along the stopper groove 51 and the other end of the link member 2 moves in a direction away from the door side fulcrum 12. Accordingly, the hinge member 1 rotates about the link rotation shaft 13. After that, when the door side pin 22 reaches the door side guide groove 5, the door side pin 22 moves to the door side shaft fulcrum 12
Is moved in the arc-shaped door-side guide groove 5 centered on the center of the door, whereby the door rotates about the door-side pivot 12 and reaches the fully open position.

In this way, from the door half open position to the door full open position,
Since the door-side shaft fulcrum 12 arranged outside the vehicle is rotated, a wide opening can be obtained.

Next, when the door is closed from the fully open position, at this time, the vehicle body side guide means places the vehicle body side pin 21 in the stopper groove 41 and restricts its movement with respect to the vehicle body. In the door side guide means, the door side pin 22 moves in the arc-shaped door side guide groove 5 centered on the door side shaft fulcrum 12, and the door rotates about the door side shaft fulcrum 12.

When the door-side pin 22 reaches the end of the door-side guide groove 5, the door reaches the vicinity of the half-open position, and when the door is further rotated in the closing direction, the door-side pin 22 moves to the stopper groove.
While moving along 51, the pin 21 on the vehicle body side
As the link member 2 moves along the
Around the center. In this way, when both pins 21 and 22 reach the end portions of both stopper grooves 41 and 51, the movement restriction on the vehicle body side pin 21 by the stopper groove 41 is released, while the movement restriction on the door side pin 22 by the stopper groove 51 is released. Done.

 Next, the operation of the embodiment will be described.

(A) When the door D is fully closed When the door D is fully closed, as shown in FIG. 1, the hinge member 1 is placed at the hinge closed position and the pillar P is closed.
And stored in the door D.

Therefore, the hinge member 1 is not exposed to the outside of the vehicle and has a good appearance.

(B) The operation of opening the door D from the fully closed state shown in FIG. 1 to the fully opened state shown in FIG. 4 will be described.

First, when the door D is opened, the door D rotates together with the hinge member 1 about the vehicle body side shaft fulcrum 11 and opens to the half open position shown in FIG.

That is, the door D is rotatable at two points of the vehicle body side shaft fulcrum 11 and the door side shaft fulcrum 12 of the hinge member 1, but in the fully closed state, as shown in FIG. Is the stopper groove 51
The door side pin 22 is located at the end position of the
The rotation of the door D with respect to the hinge member 1 is restricted with respect to the hinge member 1 (because the stopper groove 51 does not have an arc shape centering on the door side shaft fulcrum 12). Relative rotation around is restricted. On the other hand, at this time, since the vehicle body side pin 21 of the link member 2 can move in the arcuate vehicle body side guide groove 4 centered on the vehicle body side shaft fulcrum 11, the link member 2 is centered on the vehicle body side shaft fulcrum 11. When the hinge member 1 is rotated, the hinge member 1 is also pivotally supported on the vehicle body side.
Rotate around 11. In this case, the relative positional relationship between the hinge member 1 and the link member 2 does not change.

Next, when the door D is in the half-opened state as shown in FIG. 2, the vehicle body side pin 21 comes into contact with the end portion of the vehicle body side guide groove 4, and the hinge member 1 is further centered on the vehicle body side shaft fulcrum 11. Rotation is restricted.

Then, in this way, the vehicle body side pin 21 is connected to the vehicle body side guide groove 4
When the movement of the door D is restricted, the door D is rotated about the vehicle body side shaft fulcrum 11 as described below, and then the door side shaft fulcrum is rotated.
Start turning around 12.

That is, the vehicle body side pin 21 can only rotate about the vehicle body side shaft fulcrum 11 while moving in the vehicle body side guide groove 4, but when it reaches the end portion of the vehicle body side guide groove 4. Stopper groove
It becomes possible to move toward the vehicle body side shaft fulcrum 11 along 41.
Therefore, the vehicle body side pin 21 reaches the base end of the stopper groove 41,
When the door D is still rotated, the stopper groove 51 pushes the door side pin 22 away from the vehicle body side fulcrum 11 by the input from the door D, as shown in FIGS. The link member 2 itself rotates about the link rotation shaft 13 in a direction to bring the vehicle body side pin 21 closer to the vehicle body side shaft fulcrum 11, and also rotates the link rotation shaft 13 about the vehicle body side shaft fulcrum 11. It moves relative to the vehicle body as if to let it. as a result,
The pins 21 and 22 at both ends of the link member 2 move along the stopper grooves 41 and 51, respectively, and the hinge member 1 corresponds to the movement of the link rotation shaft 13 accompanying the movement of the link member 2.
Rotates slightly about the vehicle body side shaft fulcrum 11 to the hinge open position shown in FIG. After that, the pin 21 on the vehicle body side stops
41 reaches the tip and door side pin 22 stops
When the base end portion of 51 is reached, rotation of the hinge member 1 is restricted. And, at this time, the door D is 3/4 shown in FIG.
It will be open.

When the door D is opened from the half open state to the 3/4 open state as described above, the door side pin 22 must overcome the half open check piece 33 of the check link 3 against the biasing force of the second spring 32. I won't. In this way, by the urging force of the second spring 32,
Further opening of the door D from the half-open state is restricted (checked) by a predetermined force.

Further, in the 3/4 open state shown in FIG. 3, the door side pin 22 is
It is arranged in the 3/4 open check groove 34 of the check link 3. Therefore, the door D is held in this 3/4 open state based on the biasing force (checking force) of the springs 31 and 32.

Then, when the door D is rotated in the opening direction by applying a force exceeding the check force of the first spring 31 from the 3/4 open state shown in FIG. 3, the door D is centered on the door side shaft fulcrum 12. Rotate. That is, the door-side pin 22 moves in the arc-shaped door-side guide groove 5 centered on the door-side pivot 12 and, as shown in FIG. When the door D is reached, the door D is in a fully opened state in which it is rotated by approximately 180 ° from the fully closed state, and further rotation in the opening direction is restricted.

When the door 22 is in the fully opened state, the door pin 22 passes over the fully opened check piece 35, and the rotation from the fully opened state to the closed side is restricted by the urging force of the first spring 31.

Further, while the door side pin 22 is moving in the door side guide groove 5, the door side pin 22 is movable only in the circumferential direction about the door side shaft fulcrum 12 and in the radial direction of the door side shaft fulcrum 12. Movement is regulated. Therefore, the vehicle body side pin 21 of the link member 2 is restricted from moving in the radial direction of the vehicle body side rotation shaft 11 along the stopper groove 41. Therefore, the hinge member 1 is centered on the vehicle body side shaft fulcrum 11. It is restricted to rotate to.

(C) Door Closed The operation of closing the door D from the fully open state shown in FIG. 4 to the fully closed state will be described.

When a force exceeding the urging force of the first spring 31 is applied to rotate the door D in the closing direction, the door D rotates about the door side pivot 12 and the door side pin 22 causes the door side guide groove 5 to rotate. To move.

Then, when the door side pin 22 reaches the position where the door side guide groove 5 and the stopper groove 51 are connected and is delivered into the 3/4 open check groove 34 of the check link 3, 3 in FIG. / 4 Opened state.

From this state, when the check link 3 is rotated in the closing direction by a force exceeding the biasing force of the second spring 32, the door side pin 22 moves from the base end side to the tip end of the stopper groove 51, and the vehicle body side pin 21 Moves from the tip end side to the base end side in the stopper groove 41, the link member 2 moves from the position shown in FIG. 3 to the position shown in FIG. 2, and accordingly, the hinge member 1 moves toward the vehicle body side pivot point 11
Rotate from the hinge open position shown in FIG. 3 to the position shown in FIG.

Then, when the door D is further rotated in the closing direction, the door D is rotated about the vehicle body side shaft fulcrum 11 while moving the vehicle body side pin 21 along the vehicle body side guide groove 4, and FIG. Will be fully closed.

As described above, in the present embodiment, when the door D is in the fully closed state, the hinge member 1 is arranged inside the outer surface of the vehicle body B and is not exposed to the outside, so that the appearance is good.

Next, while the door D is being opened from the fully closed state to the half-opened state and the 3 / 4-opened state, the door D is pivoted about the vehicle body-side shaft fulcrum 11 arranged inside the pillar P of the vehicle body B, and this pivoting operation Side shaft fulcrum 12
After the 3/4 open state in which the vehicle is placed outside the vehicle, since the door-side pivot fulcrum 12 placed outside the vehicle rotates as a center, a wide opening can be obtained in the fully opened state.

Further, in the embodiment, since the hinge member 1 is formed in a substantially U-shape, the vehicle body side shaft fulcrum 11 of the hinge member 1 is formed.
When the door D is in the half-opened state while arranging the inside of the pillar P, the door side shaft fulcrum 12 can be arranged outside in the vehicle width direction without the hinge member 1 colliding with the pillar P. When the door is in the half-opened state and the fully-opened state, the door D does not block the opening O, and a wide opening can be obtained.

(Effect of the Invention) As described above, in the vehicle door hinge of the present invention, the vehicle body side shaft fulcrum supported by the vehicle body is supported until the door side shaft fulcrum supporting the door is arranged outside the vehicle. After the door is pivoted and the door-side pivot is located outside the vehicle, the structure is such that the door-side pivot is pivoted around the door. Although it is a structure, a wide opening can be obtained, and it is possible to obtain an effect that the two points of the rotation center can be switched by the vehicle body side guide means and the door side guide means having a simple structure by the pin and the groove. .
