Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side door structure provided on a side of a vehicle body of a vehicle, and more particularly to a side door structure which protrudes a door in parallel to a side of the vehicle body and moves in a front-rear direction to open and close.

[0002]

2. Description of the Related Art Conventionally, a side door structure of a vehicle includes a hinge door which is opened and closed by a rotating hinge provided on a vehicle body,
2. Description of the Related Art A slide door that is opened and closed by sliding on a slide rail provided on a side of a vehicle body is generally known.

[0003] Although these doors have advantages and are used in many types of vehicles, they have problems and cannot be said to have a sufficient door structure. In other words, hinge doors require a large opening / closing space to open and close the door, making it impossible to perform opening / closing operations in narrow places. In addition, sliding doors require a slide rail installation space that extends in the front-rear direction on the side of the vehicle. Thus, there is a problem that the types of vehicles that can adopt the sliding door are limited.

In order to solve these problems, Japanese Unexamined Patent Publication No. Hei 10-88896 discloses parallel doors, slide rails, and the like provided on the vehicle compartment side of the door. A door structure that moves (offset) and opens and closes has been proposed.

Specifically, the door structure is a plate-like upper link which operates as a parallel link on the vehicle compartment side of the door, one end of which is pivotally supported at the front pillar middle portion and the other end of which is pivotally supported at the door front-rear direction middle portion. And a lower link one end of which is pivotally supported at the lower end of the front pillar and the other end is pivotally supported at the lower end of the middle part of the door in the front-rear direction. , To open and close the door.

This door structure is called a glide-sliding door structure because it moves in parallel in the air away from the vehicle body. (Hereinafter, glide door structure).

According to this glide door structure, the door can be opened and closed without securing a large opening and closing space for the door, and the slide rail does not need to be set on the vehicle body, so that the applicable vehicle type is not limited. Such an effect can be obtained.

[0008]

However, according to the glide door structure, a link member such as a parallel link must be disposed on the side of the door, and a point that the door itself is separated from the vehicle body. Causes a new problem.

First, since the link member must be arranged on the side of the door, the link member is largely exposed in the vehicle compartment when the door is closed, so that the appearance from the vehicle compartment deteriorates and the space in the vehicle compartment decreases. This causes problems such as adverse effects due to a secondary collision in the vehicle.

[0010] Further, since the door itself is separated from the vehicle body, there arises a problem of how to increase the support rigidity when the door is opened.

In this respect, in the door structure disclosed in Japanese Patent Application Laid-Open No. H10-88896, a long shaft extending vertically is provided at the end of the upper link, and this shaft is fixed to the door, so that almost all of the door load can be reduced. It is supported by a link to ensure support rigidity when the door is opened.

However, when such a support structure is employed, it is necessary to considerably increase the rigidity of the upper link.
In addition, there is a problem that the provision of a new long shaft extending in the vertical direction causes an increase in weight. Furthermore, since the door support mechanism itself is a one-point cantilever support, there is a problem that rattling of the door is fundamentally unavoidable.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and when the glide door structure is employed for a side door of a vehicle, the link member is prevented from being largely exposed in the vehicle interior when the door is closed. It is another object of the present invention to provide a side door structure capable of securing support rigidity without employing a structure for supporting a door only with an upper link.

[0014]

To solve the above problems, the present invention is configured as follows.

According to a first aspect of the present invention, in a vehicle side door structure in which a door protrudes in parallel to a vehicle side via a link member and is moved in a front-rear direction to open and close, the link member is provided in a door compartment. The upper link extends vertically in the vehicle longitudinal direction at the upper and lower positions, and has an upper link and a lower link, one end of which is pivotally supported at the middle of the door in the front-rear direction and the other end of which is at the door opening edge. The support portion is set to be retracted from the door-side shaft support portion of the lower link to the front and rear end sides of the door opening edge.

According to a second aspect of the present invention, in a vehicle side door structure in which a door protrudes parallel to a vehicle side via a link member and is moved in a front-rear direction to open and close, the door is closed when the door is closed. A storage portion is set in the door so as to be stored inside.

According to a third aspect of the present invention, a storage portion is set in the door so that the upper link is stored in the door when the door is closed, and the lower link is provided between the door opening edge and the door when the door is closed. It is arranged on the outside of the vehicle at the edge of the door opening so as to be stored between the doors.

According to a fourth aspect of the present invention, in the vehicle side door structure of the second and third aspects, the storage portion is a recess formed in a side surface of the door compartment and extending in the vehicle front-rear direction.

According to a fifth aspect of the present invention, in the vehicle side door structure according to the fourth aspect, a trim member is mounted on the link member, and the trim member is mounted on the door when the door is closed. Are set so that they substantially coincide with each other.

[0020] The invention according to claim 6 is based on claims 1 and 2,
In the vehicle side door structure according to any one of claims 3, 4, and 5, a concave portion for securing a rotation space of the link member is formed at a door opening edge that pivotally supports the other end of the link member.

[0021] The invention described in claim 7 is based on claims 1 and 2,
The vehicle side door structure according to 3, 4, 5, or 6,
The other end of the link member is set at a position to be hidden from the outside between the door and the edge of the door opening when the door is closed.

[0022] The invention according to claim 8 is the invention according to claims 1 and 2,
In the vehicle side door structure according to any one of 3, 4, 5, 6, and 7, the door opening edge that pivotally supports the other end of the link member may include:
This is the front end of the rear fender.

According to a ninth aspect of the present invention, in the vehicle side door structure according to the eighth aspect, the door is a rear door, and when closed, the front end of the rear door is brought into contact with the rear end of a front door disposed forward. It is set so as to obtain a sealing function.

[0024]

According to the vehicle side door structure of the first aspect, the link member of the glide door structure is extended in the vehicle front-rear direction at each of the up and down positions on the door cabin side, and has one end at the middle of the door in the front-rear direction. The upper link and the lower link are pivotally supported at the door opening edge, and the door link of the upper link is closer to the front and rear ends of the door opening edge than the door link of the lower link. Since the upper link is set to be retracted, the amount of exposure of the upper link in the vehicle compartment can be reduced, and the door can be reliably supported by the lower arm. Therefore, the support rigidity of the door can be sufficiently ensured.

Therefore, when the glide door structure is adopted for the side door of the vehicle, the link member is prevented from being largely exposed in the cabin when the door is closed, and the structure in which the door is supported only by the upper link is adopted. Thus, it is possible to obtain a side door structure capable of securing the supporting rigidity.

According to the vehicle side door structure of the present invention, the storage portion is set in the door so that the link member of the glide door structure is stored inside the door when the door is closed. Since it is not exposed in the vehicle interior, it is possible to solve problems such as deterioration of appearance in the vehicle interior, reduction of vehicle interior space, and adverse effects due to secondary collision in the vehicle.

According to the vehicle side door structure of the third aspect, the storage portion is set in the door so that the upper link is stored inside the door when the door is closed, and the lower link is connected to the edge of the door opening when the door is closed. The upper link and lower link are not exposed at all in the cabin because they are placed outside the door opening edge so that they can be stored between the door and the door. It is possible to solve problems such as reduction and adverse effects due to a secondary collision in a vehicle.

According to the vehicle side door structure of the fourth aspect, the storage portion is a recess formed in the side of the door compartment and extending in the vehicle front-rear direction, so that the link is integrated with the door when the door is closed. Since the members can be stored, the appearance in the vehicle interior can be improved.

According to the vehicle side door structure of the fifth aspect, the trim member is mounted on the link member, and the trim member substantially coincides with the door trim member mounted on the door when the door is closed. With this setting, only the trim member is exposed in the vehicle compartment when the door is closed, so that the presence of the link member cannot be recognized at a glance, and the appearance can be more reliably improved. Also, at the time of a side collision, the trim member reduces interference between the occupant and the link member, so that occupant protection can be achieved.

According to the vehicle side door structure of the present invention, the link member is provided with a concave portion at the edge of the door opening which supports the other end of the link member to secure the rotation space of the link member. Can be secured sufficiently, so that the opening amount of the door can be increased.

According to the vehicle side door structure of the present invention, the pivot at the other end of the link member is set at a position to be hidden from the outside between the door and the door opening edge when the door is closed. Thus, the link member can be pivotally supported on the door opening edge without deteriorating both the appearance from outside the vehicle body and the appearance from the vehicle interior when the door is closed.

According to the vehicle side door structure of the present invention, since the edge of the door opening that supports the other end of the link member is the front end of the rear fender, the rigidity of the door opening edge is compared. Since the link member is pivotally supported at the front end of the rear fender, the support rigidity of the door can be reliably ensured.

According to the vehicle side door structure of the ninth aspect, the glide door is a rear door, and when closed, the front end of the rear door is brought into contact with the rear end of the front door disposed forward to obtain a sealing function. By setting to, the rear door and the front door will be contacted and sealed, so even in a center pillarless vehicle where the pillar member is not provided between the front door and the rear door,
The sealing performance in the vehicle interior can be ensured.

20 is constituted by two L-shaped link portions 122 and 123, and a door trim member 143 is provided with two notch storage portions 145 extending in the vehicle front-rear direction corresponding to the rotation locus of the L-shaped link portion.

As described above, the notch storage portion 145 is provided in the door trim member 143, and the upper link 120 is stored in the notch storage portion 145 when the door is closed. The appearance of the room can be secured so that the presence of the upper link cannot be recognized at a glance.

In particular, in the case of this embodiment, unlike the above-described embodiment, the trim member does not have to be attached to the upper link, so that the number of parts can be reduced and the assembling work can be simplified.

The other configuration is the same as that of the above-described embodiment, and the same reference numerals as those in FIG.

The embodiment shown in FIG.
43, a storage portion is not provided, and the trim member 246 itself mounted on the upper arm 220 is set large so as to cover the entire upper half rear of the rear door RD, and at a storage position 245 of the upper half rear of the rear door RD, Door trim member 243
Apart from this, the interior of the vehicle is constructed.

As described above, the storage portion is not provided in the door trim member 243 itself, and the trim member 246 of the upper arm 220 covers the entire rear half of the upper half of the rear door 245. It is possible to secure the appearance of the cabin and make it impossible to recognize the presence of the upper link at a glance.

In particular, in the case of this embodiment, unlike the above-described embodiment, it is not necessary to provide a housing portion in the door trim member, so that the door trim member can be easily formed.

These embodiments have the following effects by being constructed and operated as described above.

First, the door-side pivot of the upper link is
By setting the lower link to be retracted to the rear edge of the door opening (rear side of the vehicle) from the door-side support portion of the lower link, the amount of exposure of the upper link in the vehicle compartment can be reduced, and the door is reliably supported by the lower arm. Therefore, the support rigidity of the door can be sufficiently ensured.

Therefore, even if the door has a glide door structure, it is possible to prevent the link member from being largely exposed in the vehicle compartment when the door is closed, and to adopt a support rigidity without employing a structure in which the door is supported only by the upper link. Can be secured.

Although the rear door is used as the target door in the embodiment, for example, when the target door is a front door and the door moves toward the front of the vehicle, it is preferable to set an upper link on the front of the vehicle. .

Next, a storage portion (storage recess, notch storage portion, storage position) is set in the door so that the upper link is stored in the door when the door is closed, so that the door is exposed to the vehicle interior when the upper link door is closed. Therefore, it is possible to solve problems such as deterioration of the appearance in the vehicle interior, reduction of the space in the vehicle interior, and adverse effects due to the secondary collision in the vehicle.

In particular, when the upper link is provided with a trim member, the trim member substantially coincides with the door trim member on the side of the vehicle compartment when the door is closed, so that only the trim member is exposed in the vehicle compartment when the door is closed. The appearance can be more reliably improved. Also, at the time of a side collision, the trim member reduces interference between the occupant and the upper link, so that occupant protection can be achieved.

In addition, since the concave cover plate is provided so as to surround the shaft-supporting portion of the upper link on the vehicle body side, a sufficient amount of rotation of the upper link can be secured, so that the opening amount of the door can be increased. Can be.

Further, since the vehicle body-side supporting portion of the upper link is set at a position that is concealed from the outside between the rear end of the rear door and the front end of the rear fender, the appearance from outside the vehicle body when the door is closed can be improved. The glide door can be constructed without deteriorating the appearance.

Further, since the door opening edge supporting the vehicle body-side supporting portion of the upper link is the front end of the rear fender (specifically, the side frame outer panel), rigidity is provided in the door opening edge. Since the link member is pivotally supported at the relatively high front end of the rear fender, the support rigidity of the door can be reliably ensured.

Although the embodiments have been described above, the present invention is not limited to these embodiments, but adopts a glide door structure for the side door, and takes into consideration the relationship between the upper link and the lower link. As long as the link member is not exposed to the interior of the vehicle as much as possible and the support rigidity of the door is assured, all of the present invention is encompassed by the present invention, and the details may be appropriately modified without departing from the spirit of the present invention. The structure may be changed.
