Description

  The present invention relates to a vehicle door structure in which a door is provided at a door opening of a vehicle body so as to be opened and closed.

A vehicle door structure in which a vehicle is provided with a catcher pin facing the vehicle body width direction, a side pin is provided with a catcher pin receiving portion, and the catcher pin is inserted into the catcher pin receiving portion when the door is closed. It has been known.
The inner diameter of the catcher pin receiving portion is formed relatively large with respect to the outer diameter of the catcher pin.

According to this vehicle door structure, in the case of a side collision, the catcher pin can be restrained by the catcher pin receiving portion to prevent the door from entering the vehicle body (see, for example, Patent Document 1). ).
JP 2004-122874 A

However, in the vehicle door structure of Patent Document 1, the catcher pins protrude in the vehicle body width direction (that is, the door opening / closing direction). Further, the catcher pin receiving portion is formed to have a relatively large inner diameter with respect to the outer diameter of the catcher pin.
Therefore, the door structure of the vehicle of Patent Document 1 cannot restrain the door with respect to the opening direction.
For this reason, when the vehicle is traveling, vibrations in the door opening / closing direction may occur in a portion of the door opposite to the hinge.

  This invention makes it a subject to provide the door opening part structure of the vehicle which can restrain a door favorably.

  According to a first aspect of the present invention, in a vehicle door structure including a door supported by a door opening of a vehicle body and capable of opening and closing the door opening, the door opening is provided between the door opening and the support side of the door. Hinge means for supporting the door in a swingable manner in the horizontal direction, and provided between the door opening and the support side, and allowing downward displacement due to the weight of the door when the door is closed. And a lower side fitting means for fitting the lower side of the door to the door opening when the door is displaced downward.

  In the invention according to claim 2, the displacement allowance means includes a first displacement allowance means for movably supporting the hinge means in response to a downward displacement due to the weight of the door, and when the door is opened. And a second displacement permitting means for restricting downward displacement due to the dead weight of the door and permitting downward displacement due to the dead weight of the door when the door is closed.

  According to a third aspect of the present invention, there is provided an opposing side fitting means for fitting the door facing side facing the support side into the door opening when the door is displaced downward.

  The invention according to claim 4 is characterized in that the first displacement permitting means includes spring means for biasing the door in a direction in which the door is opened when the door is closed.

  The invention according to claim 5 is characterized in that the first displacement allowing means includes a displacement amount restricting means for restricting a downward displacement amount of the door.

The invention according to claim 1 is provided with a displacement allowing means and a lower side fitting means. When the door is closed, the displacement permitting means allows the downward displacement due to the weight of the door. When the door is displaced downward, the lower side fitting means fits the lower side of the door and the door opening.
Therefore, the door can be restrained well, and the so-called “closing rigidity” of the door can be increased.
Accordingly, there is an advantage that it is possible to prevent the door from being vibrated or loose when the vehicle travels.

Further, by restraining the door well and increasing the “closing rigidity” of the door, there is an advantage that when the door receives a load due to a side collision, the deformation of the door can be regulated.
In addition, since the vehicle body rigidity can be increased by increasing the “closing rigidity” of the door, the running stability can also be improved.

Further, when the door is closed, the door is displaced downward only by its own weight.
Accordingly, there is an advantage that the door can be displaced downward without using a drive source such as an actuator, and the structure can be simplified.

In the invention according to claim 2, the displacement permission means is divided into a first displacement permission means and a second displacement permission means. Then, the first displacement permitting means moves the hinge means corresponding to the downward displacement of the door.
On the other hand, the second displacement permitting means regulates the downward displacement of the door when the door is opened.

Thus, by dividing the displacement permission means into the first and second displacement permission means according to their roles, the first and second displacement permission means can be compactly combined.
Thereby, there exists an advantage that a displacement permission means can be easily provided in the comparatively narrow space between a door opening part and a support side.

In the invention according to claim 3, when the door is displaced downward, the opposed side fitting means is adapted to fit the door facing side facing the support side and the door opening.
Accordingly, there is an advantage that the door can be restrained more satisfactorily to prevent the door from being vibrated or loose when the vehicle travels.

In the invention which concerns on Claim 4, the spring means was provided in the 1st displacement permission means. The spring means biases the door in the direction in which the door is opened when the door is closed.
Therefore, when the door is opened from the closed position to the open position, the biasing force of the spring means can be used as a force for opening the door.
As a result, the door that has been displaced downward by its own weight can be raised to the position before the displacement with a relatively small operating force, and there is an advantage that the operability can be improved.

In the invention which concerns on Claim 5, the displacement amount control means was provided in the 1st displacement permission means. The displacement amount restricting means restricts the downward displacement amount of the door.
Accordingly, there is an advantage that the door can be prevented from being displaced more than necessary and the operability of the door can be improved.

In the upper first displacement allowance means 33, upper and lower guide rails 51 and 52 are attached to the upper part of the front end portion 12 a of the door opening 12, and the movable body 81 is movable in the longitudinal direction of the vehicle body on the upper and lower guide rails 51 and 52. Is attached.
The upper and lower guide rails 51 and 52 are arranged at a predetermined interval in the vertical direction. As shown in FIGS. 3 and 4, the upper and lower guide rails 51 and 52 are formed in an arc shape around the support shaft 41 of the lower first displacement allowance means 32.

  A bracket 82 is attached to the rear of the moving body 81, and an upper return spring 83 is provided between the bracket 82 and the moving body 81. The upper return spring 83 is a member that biases the moving body 81 in the direction of arrow F.

  By providing the upper return spring 83 in the upper first displacement allowance means 33, when the door 14 is opened in the arrow B direction from the door closed position shown in FIG. The upper hinge means 26) can be biased in the direction of arrow F (ie, door opening direction).

That is, the upper return spring 83 is a member that urges the door 14 in the opening direction when the door 14 is closed as shown in FIG.
By providing the upper return spring 83 in the upper first displacement allowance means 33, the operating force when opening the door 14 can be reduced.

The upper hinge means 26 is attached to the moving body 81. In the upper hinge means 26, a fixed hinge portion 71 is attached to a moving body 81 with bolts 85 and nuts 86, and a rotating hinge portion 73 is rotatably attached to the fixed hinge portion 71 via a support pin 72.
As shown in FIG. 3, the front end portion 14 a of the door 14 is attached to the rotating hinge portion 73 with a bolt 74.
Therefore, the door 14 can move in the direction of the arrow F or the direction of the arrow G (see FIG. 4) together with the moving body 81.

7 is an exploded perspective view showing the lower second displacement allowance means of the door structure according to the present invention, FIG. 8A is a perspective view showing the lower second displacement allowance means in the door closed position, and FIG. 8B is the door. It is a perspective view which shows the 2nd displacement permission means under an open position.
The guide block 55 of the lower second displacement allowance means 36 has an outer wall 55a attached to the front end 12a of the door opening 12, a restriction surface 57 formed horizontally on the upper surface 55b, and a storage recess at the front end of the restriction surface 57. 58 is formed.

On the other hand, the movement support bar 56 of the lower second displacement allowance means 36 is a member formed in an approximately L shape in plan view, with the base end portion 56a attached to the front end portion 14a of the door 14 and the tip end portion 56b facing downward. It is protruding.
The movement support bar 56 is a member that can move in a state in which the distal end portion 56 b is in contact with the regulation surface 57 of the guide block 55 and can be advanced into the storage recess 58.

According to the lower second displacement allowance means 36, the distal end portion 56b of the movement support bar 56 abuts against the regulating surface 57 when the door 14 is opened as shown in FIG.
Thereby, the door 14 is restricted from being displaced downward by its own weight.
On the other hand, according to the lower second displacement allowance means 36, as shown in FIG. 8B, when the door 14 is closed, the distal end portion 56b of the moving support bar 56 enters the storage recess 58.
Thereby, the door 14 is allowed to be displaced downward by the weight of the door 14.

As described above, when the door 14 is closed, the door 14 is displaced downward only by its own weight.
Accordingly, the door 14 can be displaced downward without using a drive source such as an actuator, and the structure can be simplified.

Further, as described with reference to FIGS. 5 to 8, the displacement permission means 16 is divided into the first displacement permission means 31 and the second displacement permission means 35. The first displacement permitting means 31 moves the hinge means 15 in accordance with the downward displacement of the door 14.
On the other hand, the second displacement permitting means 35 regulates the downward displacement of the door 14 when the door 14 is opened.

Thus, by dividing the displacement permission means 16 into the first and second displacement permission means 31 and 35 according to their roles, the first and second displacement permission means 31 and 35 can be compactly combined. It becomes possible.
Thereby, the displacement permission means 16 can be easily provided in a relatively narrow space between the front end portion 12 a of the door opening 12 and the front end portion 14 a of the door 14.

As an example, the lower receiving portion 91 is a rubber member, and a lower fitting groove 93 is formed on the upper surface 91a.
For example, the lower insertion portion 92 is a metal member, protrudes downward from the lower end portion 14 b of the door 14, and is formed so as to be fitted in the lower fitting groove 93.

As shown in FIG. 9B, when the door 14 is closed to the door closed position, the lower insertion portion 92 is positioned above the lower fitting groove 93.
When the door 14 is disposed at the door closed position, the door 14 is displaced downward as indicated by an arrow A about the support shaft 41 of the lower first displacement allowance means 32 shown in FIG.

Therefore, the lower end portion 14b of the door 14 is displaced downward as indicated by an arrow H, and the lower insertion portion 92 is fitted into the lower fitting groove 93 as shown in FIG.
Thereby, the lower end fitting part 45 can fit the lower end part 14 b of the door 14 to the door opening part 12.

10A is a cross-sectional view taken along the line 10a-10a in FIG. 1, and FIG. 10B is a cross-sectional view showing a state before the door is displaced downward.
The opposite side fitting means 46 of the fitting means 17 includes a rear receiving portion 95 provided in the rear end portion (that is, the center pillar 23) 12c of the door opening portion 12 and the rear end portion (door opposite side) of the door 14. And a rear insertion portion 96 provided in 14c.
As an example, the rear receiving portion 95 is a rubber member similar to the lower receiving portion 91, and a rear fitting groove 97 is formed in the front surface 95a.
The rear insertion portion 96 is a metal member, for example, and protrudes rearward from the rear end portion 14 c of the door 14, and is formed so as to be fitted in the rear fitting groove 97.

As shown in FIG. 10B, the rear insertion portion 96 is positioned in front of the rear fitting groove 97 when the door 14 is closed to the door closed position.
When the door 14 is disposed at the door closed position, the door 14 is displaced downward as indicated by an arrow A about the support shaft 41 of the lower first displacement allowance means 32 shown in FIG.

Therefore, the rear end portion 14c of the door 14 is displaced rearward as indicated by the arrow I, and the rear insertion portion 96 is fitted into the rear fitting groove 97 as shown in FIG.
Thereby, the rear end portion 14 c of the door 14 can be fitted to the door opening 12 by the facing side fitting means 46.

As shown in FIGS. 9 and 10, the lower edge fitting means 45 fits the lower end portion 14 b of the door 14 to the door opening 12, and the opposed edge fitting means 46 connects the rear end portion 14 c of the door 14 to the door. The opening 12 is fitted.
Therefore, the door 14 can be restrained favorably, and so-called “closing rigidity” of the door 14 can be increased.

Thereby, it is possible to prevent the door 14 from being vibrated or loose when the vehicle travels.
Further, by restraining the door 14 well and increasing the “closing rigidity” of the door 14, when the door 14 receives a load due to a side collision, the deformation of the door 14 can be restricted.
In addition, since the vehicle body rigidity can be increased by increasing the “closing rigidity” of the door 14, traveling stability can also be improved.

Next, the operation of the vehicle door structure 10 will be described with reference to FIGS.
FIGS. 11A and 11B are views for explaining the operation of closing the door of the door structure according to the present invention.

Here, as shown in FIG. 5, the lower first displacement allowing means 32 is provided with a displacement amount regulating means 76. Therefore, the displacement amount of the door 14 can be regulated by the displacement amount regulating means 76.
Thereby, the door 14 can be prevented from being displaced downward more than necessary, and the operability of the door 14 can be improved.

In (b), the lower end portion 14 b of the door 14 is displaced downward, and the lower insertion portion 92 is fitted into the lower fitting groove 93 of the lower receiving portion 91.
Thereby, the lower end fitting part 45 can fit the lower end part 14 b of the door 14 to the door opening part 12.

In (c), the rear end portion 14 c of the door 14 is displaced rearward, and the rear insertion portion 96 is fitted into the rear fitting groove 97 of the rear receiving portion 95.
Thereby, the rear end portion 14 c of the door 14 can be fitted to the door opening 12 by the facing side fitting means 46.

  As shown in (b) and (c), the lower end fitting means 45 fits the lower end portion 14b of the door 14 into the door opening 12, and the opposing side fitting means 46 further uses the rear end portion 14c of the door 14. Is fitted to the door opening 12.

As a result, when the vehicle travels, vibration and backlash are generated in the door 14, and when the door 14 receives a load due to a side collision, the deformation of the door 14 can be restricted.

FIGS. 14A and 14B are views for explaining the operation of opening the door of the door structure according to the present invention.
In (a), the door 14 is opened from the closed state. The door 14 swings (swings) in the direction of arrow N about the upper and lower hinge means 26, 25 (see FIG. 3).

  In (b), when the door 14 is opened in the arrow N direction, the distal end portion 56 b of the moving support bar 56 moves in the arrow O direction and comes into contact with the inclined surface 58 a of the storage recess 58.

FIGS. 15A and 15B are views for explaining a state in which the door of the door structure according to the present invention is opened.
In (a), as shown in FIG. 5 (b), the lower first displacement permissive means 32 is provided with a lower return spring 68 to urge the door 14 in the door opening direction.
Further, as shown in FIG. 6A, the upper first displacement permissive means 33 is provided with an upper return spring 83, thereby biasing the door 14 in the door opening direction.

By using the urging force of the lower return spring 68 and the upper return spring 83, the distal end portion 56b of the movable support bar 56 is raised along the inclined surface 58a even if the operation force when opening the door 14 is kept relatively small. Can be made.
Therefore, the distal end portion 56b of the moving support bar 56 gets over the inclined surface 58a and is guided to the regulating surface 57 as indicated by the arrow P.

Thus, when the door 14 is opened from the closed position of the door 14 to the open position, the urging force of the lower return spring 68 and the upper return spring 83 can be used as a force for opening the door 14.
As a result, the door 14 that has been displaced downward by its own weight can be raised to a position before the displacement with a relatively small operating force, and operability can be improved.

In (b), in a state where the door 14 is opened, the tip end portion 56 b of the movement support bar 56 is kept in contact with the restriction surface 57.
By maintaining a state in which the distal end portion 56 b of the moving support bar 56 is in contact with the restriction surface 57, the door 14 is restricted from being displaced downward by the weight of the door 14.
Thereby, the door 14 can be swung (swinged) in the horizontal direction to open the door 14 to the door open position.

  In the above-described embodiment, the two means of the lower side fitting means 45 and the opposite side fitting means 46 are used as the fitting means 17, but the present invention is not limited to this, and only the lower side fitting means 45 may be used. Is possible.

  In the above-described embodiment, two means, that is, the lower second displacement allowance means 36 and the upper second displacement allowance means 37 are used as the second displacement allowance means 35. However, the present invention is not limited to this. Either one of 37 can also be used.

Furthermore, in the above-described embodiment, the example in which the lower first displacement permissible means 32 is provided with the displacement amount restricting means 76 has been described. It is also possible to provide.
When the displacement amount restricting means 76 is provided in the upper first displacement permitting means 33, as an example, it is conceivable to provide a stopper for restricting the movement of the moving body 81 on the upper and lower guide rails 51 and 52.

  In the above embodiment, the lower receiving portion 91 and the rear receiving portion 95 have been described as rubber members, and the lower insertion portion 92 and the rear insertion portion 96 have been described as metal members. It can be changed.
