Description

  The present invention relates to a slide door structure of a vehicle such as a car.

As a specific example of a slide door structure of a vehicle, there are those described in Patent Documents 1 and 2.
In the structure described in these documents, when the slide door is closed, a side collision of the vehicle occurs, and a large load is applied, for example, when a load or an occupant collides from the vehicle interior side toward the slide door. In this case, the gap between the upper end portion of the slide door and the like and the side surface of the vehicle body is intended to be reduced. As a means for that purpose, in the above document, a predetermined portion of the slide door is a fragile portion, and when the slide door receives a load, the deformation of the slide door is controlled so as not to form a large gap with the side surface of the vehicle. Means are adopted.

  However, in the above-mentioned prior art, since the gap between the slide door and the side surface of the vehicle is to be reduced by controlling the deformation of the slide door at the time of load input, certain limitations are imposed in reducing the gap. There is. Therefore, there is still room for improvement in reducing the gap.

  As another means for reducing the gap, for example, as described in Patent Document 3, it is conceivable to provide a dedicated member for preventing the slide door from being displaced in the vehicle width direction at the time of load input. . However, according to such means, problems such as an increase in manufacturing cost and an increase in weight occur.

  Also, in the prior art, the front of the slide door is disposed on the inward side in the vehicle width direction of the rear (hem section) of the front door located on the vehicle front side of the slide door. By bringing the front part of the slide door into contact with the rear part of the front door, means for preventing the slide door from projecting largely outward in the vehicle width direction is also suitably adopted. However, in such conventional means, the contact width when the front part of the slide door and the rear part of the front door contact is small, and the contact parts of the two are deformed largely due to the contact parts being largely deformed. It is easy to get rid of the condition. In this case, it is difficult to reliably prevent the slide door from protruding largely outward in the vehicle width direction, and a large gap may be generated between the slide door and the side surface of the vehicle.

  The present invention has been conceived under the circumstances as described above, and when a large load is applied to the slide door from the vehicle interior side, a large gap is generated between the slide door and the side surface of the vehicle. It is an object of the present invention to provide a slide door structure of a vehicle which can be appropriately prevented by means having a simple configuration without using expensive dedicated members and the like.

  In order to solve the above problems, the present invention takes the following technical measures.

  The slide door structure of a vehicle provided by the present invention comprises a slide door which is hollow with an outer panel and an inner panel joined together and on which a reinforcing member is disposed at an inner front portion, the slide door A sliding door structure of a vehicle, which is located on the vehicle rear side of a front door or a pillar of the vehicle, and a front and rear extending wall portion extending in the longitudinal direction of the vehicle is provided at a front portion of the outer panel; The front-rear extending wall portion is located inward in the vehicle width direction than the outer-rear portion of the front door or pillar, and overlaps the outer-rear portion of the front door or pillar in the vehicle front-rear direction. The reinforcing member is provided with an inclined wall portion which is inclined so as to be positioned on the outer side in the vehicle width direction toward the rear side of the vehicle, and the inclined wall At least a portion of the is characterized in that the located in the vehicle width direction inner side than the rear end portion of the front and rear extension 設壁 portion opposed to the rear end portion.

According to such a configuration, the following effects can be obtained.
That is, when a large load acts on the slide door from the vehicle compartment and the front portion of the slide door is displaced in the vehicle width direction, the inclined wall portion of the reinforcing member is the rear width portion of the front and rear extension wall portion of the slide door Press outward in the direction. Then, the front and rear extending wall portions are also pressed toward the vehicle front side by the tilting action of the sloped wall portions. As a result, the front and rear extending wall portions come into contact with the outer side and the rear portion of the front door or the pillar in a state in which the overlap amount in the vehicle front and rear direction is large. be able to. Therefore, using the front door or the pillar, it is possible to appropriately prevent the front part of the slide door from protruding largely toward the vehicle outer side, and to prevent a large gap from being generated between the slide door and the vehicle side surface. it can.
According to the present invention, there is no need to use a special or expensive special member, and the whole configuration can be simplified, so that the productivity is good, the manufacturing cost is reduced, and the weight of the vehicle is reduced. You can also.

  Other features and advantages of the present invention will become more apparent from the description of the embodiments of the present invention given below with reference to the attached drawings.

(a) is a schematic side view which shows an example of the vehicle to which this invention is applied, (b) is Ib-Ib plane sectional drawing of (a). In the structure shown in FIG.1 (b), it is a plane sectional view which shows an effect | action when load input generate | occur | produces in a slide door.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

The slide door structure A of the vehicle shown in FIG. 1 includes a slide door SD (slide side door) capable of slidingly opening and closing the entry / exit opening 8 provided on the side surface of the vehicle V. Since the slide structure of the slide door SD is conventionally known, the description thereof is omitted.
The vehicle V is a pillarless system in which the center pillar is not provided, and the slide door SD is positioned on the vehicle rear side of the hinged front door 4 (front side door) without the center pillar. As will be described later, predetermined portions of the rear portion of the front door 4 and the front portion of the slide door SD overlap in the longitudinal direction of the vehicle.
In the present embodiment, the positional relationship of each place is a positional relationship in a state in which the slide door SD and the front door 4 are closed.

The slide door SD has a hollow shape in which the outer panel 1 and the inner panel 2 are joined, and the reinforcing panel 3 in which the inclined wall portion 30 is formed, and the front and rear extending wall portions 10 provided in the front of the outer panel 1 Have.

  The front and rear extending wall portion 10 is a portion formed in the middle of the front wall portion 1a of the outer panel 1 so as to extend in the longitudinal direction of the vehicle by an appropriate dimension La, and in the vertical height direction of the vehicle V It is provided in a standing shape with appropriate dimensions. The front wall portion 1 a of the outer panel 1 is a wall portion extending from the front end portion 18 of the outer side portion of the outer panel 1 to the front end side hem portion 28 of the outer panel 1 and the inner panel 2. Front and rear extending wall portion 10 is positioned inward in the vehicle width direction than outboard rear portion 42 including outer panel 40 of front door 4 and rear end side hem portion 42a of inner panel 41, and is outside in the vehicle longitudinal direction It is provided in an overlapping arrangement with the rear portion 42. For example, another wall 11 extending in the vehicle width direction of the front wall 1a is connected to the rear end 10a of the front-rear extending wall 10, and the rear end 10a includes the wall 11 and the front-rear extending wall It has become a corner where the 10 intersects.

  The reinforcing panel 3 corresponds to an example of the "reinforcing member" in the present invention, and the front end 3a is sandwiched and joined to the front end side hem 28 and the rear end 3b is welded to the inner panel 2 It is joined using the means of. The inclined wall portion 30 is formed at an intermediate position in the vehicle longitudinal direction of the reinforcing panel 3 and is inclined so as to be positioned outward in the vehicle width direction toward the vehicle rear side. At least a portion of the inclined wall portion 30 is positioned inward of the rear end portion 10 a of the front-rear extending wall portion 10 in the vehicle width direction and faces the rear end portion 10 a. Further, the inclined wall portion 30 is provided so as to be located in a height range substantially similar to the front and rear extending wall portion 10 in the vertical height direction of the vehicle V.

  Next, the operation of the above-described slide door structure A of the vehicle will be described.

As an example, as shown in FIG. 1B, consider the case where the object 9 strongly collides with the front part of the slide door SD from the vehicle interior side and a large load F is input to the slide door SD.
First, when the object 9 collides with the slide door SD, the inner panel 2 and the reinforcing panel 3 of the slide door SD are deformed outward in the vehicle width direction prior to the outer panel 1. For this reason, the inclined wall portion 30 of the reinforcing panel 3 collides with the rear end portion 10 a of the front and rear extending wall portion 10 of the outer panel 1 and presses the rear end portion 10 a outward in the vehicle width direction.

  However, since the inclined wall portion 30 is inclined in the direction described above, the rear end portion 10a of the front and rear extending wall portion 10 should be pressed toward the vehicle diagonally forward side indicated by the arrow Na in FIG. It becomes. Therefore, the front and rear extending wall portion 10 is displaced not only in the vehicle width direction outward side but also in the vehicle front side. As a result, as shown in FIG. 2, the front and rear extending wall portion 10 reliably abuts on the outboard rear portion 42 of the front door 4, and the contact amount Lb (overlap dimension) thereof becomes large. As a result, the contact state between the slide door SD and the front door 4 is easily released, and large displacement of the slide door SD outward in the vehicle width direction is appropriately eliminated. As a result, it is possible to prevent a large gap from occurring between the slide door SD and the side surface of the vehicle.

  The reinforcing panel 3 is originally provided in the slide door SD, and in the present embodiment, it is not necessary to separately use a special dedicated member. Therefore, it is possible to simplify the overall configuration and to preferably reduce the manufacturing cost and the weight.

  The present invention is not limited to the contents of the embodiments described above. The specific configuration of each part of the slide door structure of the vehicle according to the present invention can be variously designed and changed within the intended scope of the present invention.

In the above-mentioned embodiment, although the pillarless type vehicle was explained as an example, the present invention is not limited to this. The present invention is also applicable to a vehicle provided with a center pillar. When the pillar is provided on the vehicle front side of the slide door, the front and rear extension wall portion of the slide door may be configured to be in contact with the outer side and the rear of the pillar. The pillar is not limited to the center pillar. The slide door is not limited to the rear side door, but may be a front side door located on the vehicle rear side of the front pillar.
The reinforcing member in the present invention does not have to be in the form of a panel, and may be a reinforcing member in the form of, for example, a band other than the panel.
The front and rear extending wall portions referred to in the present invention may be extended in the vehicle longitudinal direction so as to have a certain dimension in the vehicle longitudinal direction, and the specific dimensions thereof are not limited. In addition, the direction in which the front and rear extension walls extend does not have to be the vehicle longitudinal direction in a strict sense, but in the vehicle longitudinal direction with a slight inclination angle with respect to the vehicle longitudinal direction in a strict sense It may be in an extended configuration.
