JP, 2016-144979, A

When an external force such that the door inner panel is deformed rearward is applied to the side door from the front side of the vehicle due to a frontal collision of the vehicle or the like, the door trim may be deformed due to the deformation of the door inner panel. The door trim generally has an accommodating portion that is accommodated between the door inner panel and the door outer panel from the opening of the door inner panel in order to widen the space in the vehicle interior. When the door inner panel or the door trim is deformed, the storage part is deformed or displaced rearward. At that time, the accommodation portion may come into contact with the opening edge of the opening, and the opening edge of the door inner panel may be deformed toward the door outer panel side. When the door lock device is arranged near the opening edge, the opening edge contacts the door locking device. If the door lock device is damaged by this contact, the side door cannot be unlocked.

An object of the present invention is to provide a side door structure having a simple structure and capable of preventing damage to the door lock device when an external force that deforms the door trim acts from the front side or the rear side of the vehicle. is there.

(1) The side door structure according to one aspect of the present invention is
A side door body having a door inner panel and a door outer panel,
A door trim that covers the inside of the door inner panel,
A door lock device that is arranged between the door inner panel and the door outer panel and locks the side door body,
The door inner panel is
A facing area facing the door lock device,
And an opening provided in one of the front and the rear of the vehicle in the facing area,
The door trim has a housing portion housed between the door inner panel and the door outer panel from the opening,
At least one of the door inner panel and the door trim is configured such that the accommodation portion and the opening edge of the opposing area are brought into contact with each other by the deformation of the door trim caused by an external force from the front side or the rear side of the vehicle, and thus the opposing area is formed. There is a deformation inducing portion that deforms so as to separate from the door lock device.

(2) As one form of the side door structure,
The deformation inducing portion projects from an outer surface of the vehicle in the accommodation portion between the door inner panel and the door outer panel, and the opening edge of the facing region is abutted by the contact between the accommodation portion and the opening edge. It is possible to cite that it has a stop portion that restricts the movement to the outside.

The deformation inducing portion may include a bent portion that is locally provided in the facing area and that bends the facing area so as to be convex inward of the vehicle.

The side door structure of the above (1) has a simple structure having a deformation inducing portion, and even if an external force such that the door trim is deformed acts on the side door structure from the front side or the rear side of the vehicle, Can prevent damage. This is because the deformation inducing portion deforms the facing area of the door inner panel away from the door lock device, so that contact between the facing area of the door inner panel and the door lock device can be suppressed. Therefore, the side door body can be unlocked. In this way, damage to the door lock device can be suppressed with a simple configuration.Thus, in order to increase the rigidity of the door inner panel so that the door trim does not deform, the thickness of the door inner panel must be increased or the door inner panel must be provided separately. It is not necessary to provide a reinforcing material. Therefore, increase in weight, increase in cost, and decrease in productivity are unlikely to occur.

In the side door structure of the above (2), when an external force such that the door trim is deformed acts on the side door structure from the front side or the rear side of the vehicle, the stop portion moves the opening edge of the facing region to the outside of the vehicle. By restricting it, it is easy to surely prevent contact with the door lock device in the facing area.

In the side door structure of the above (3), when an external force such that the door trim is deformed acts on the side door structure from the front side or the rear side of the vehicle, the bent portion is bent toward the inside of the vehicle, so that It is easy to reliably prevent contact with the door lock device. Moreover, it is easy to form the bent portion.

<<Embodiment 1>>
[Side door structure]
The side door structure 1 according to the first embodiment includes a side door body 2, a door trim 3 that covers the vehicle interior side of the side door body 2, and a door lock device 4 that locks the side door body 2 (FIG. 1 ). The side door body 2 has a door inner panel 21 and a door outer panel (not shown). FIG. 1 shows a side door structure 1 when the door outer panel of the side door main body 2 is removed from the outside of the vehicle. The door lock device 4 is arranged between the door inner panel 21 and the door outer panel. The door inner panel 21 has a facing area 211 (FIG. 2) facing the door lock device 4 and an opening 212 (FIG. 1, FIG. 2) provided in the facing area 211 either in front of or behind the vehicle. The door trim 3 has a housing portion 31 that is housed between the door inner panel 21 and the door outer panel from the opening 212. One of the features of this example is that the deformation inducing portion 5 that deforms the facing area 211 so as to separate it from the door lock device 4 when an external force such that the door trim 3 is deformed acts from the front side or the rear side of the vehicle. It is provided on at least one of the door inner panel 21 and the door trim 3. The details will be described below.

[Side door body]
The side door body 2 opens and closes left and right door openings (not shown) of the vehicle (FIG. 1 ). The side door body 2 may be a front side door body or a rear side door body of the vehicle. The side door main body 2 is a hinge type in this example, and is rotatably fixed to a portion forming a front side edge of a door opening in a vehicle (for example, an A pillar lower or a B pillar) via the hinge (any one. Is also not shown). In FIG. 1, the side door body 2 shows the side door body 2 on the right front side of the vehicle. The side door body 2 may be a slide type provided on the left and right rear sides of the vehicle.

The side door body 2 has a door inner panel 21 and a door outer panel, and is formed in a hollow shape with a space provided between the door inner panel 21 and the door outer panel. The door lock device 4 and the like are arranged in this space. The door inner panel 21 is arranged inside the door lock device 4, and the door outer panel is arranged outside the door lock device 4. The door inner panel 21 and the door outer panel are made of a plate material.

The door inner panel 21 has a facing area 211 and an opening 212. The facing area 211 faces the door lock device 4. The opening 212 is provided on the front side or the rear side of the vehicle in the facing area 211. The positional relationship between the facing region 211 and the opening 212 along the front-rear direction of the vehicle can be appropriately selected depending on whether the side door body 2 is a hinge type or a slide type. Although the details will be described later, the location of the door lock device 4 can be appropriately selected depending on whether the side door body 2 is a hinge type or a slide type. In this example, the positional relationship between the facing area 211 and the opening 212 is that the facing area 211 is the rear side and the opening 212 is the front side on the vehicle rear side of the side door body 2. This opening portion 212 corresponds to the position of the armrest portion.

[Door trim]
The door trim 3 is a member that covers the inside of the vehicle of the door inner panel 21. The door trim 3 has a housing 31 (FIG. 2). The housing portion 31 is housed between the door inner panel 21 and the door outer panel through the opening 212 of the door inner panel 21. The accommodating portion 31 is formed in a convex shape protruding to the outside of the vehicle. The interior of the vehicle (the space of the armrest portion) can be widened by the convex concave portion formed inside the vehicle.

[Door lock device]
The door lock device 4 locks the side door body 2 with respect to the vehicle body. The location of the door lock device 4 can be appropriately selected depending on whether the side door body 2 is a hinge type or a slide type. In the front or rear hinge type side door body 2, when the hinge for fixing the side door body 2 to the vehicle body is on the front side, the door handle is provided on the rear side of the vehicle in the side door body 2, The door lock device 4 is provided on the rear side of the vehicle in the side door body 2. In the case of the rear slide type side door body 2, the door handle is provided on the side door body 2 on the front side of the vehicle, and the door lock device 4 is provided on the side door body 2 on the front side of the vehicle. The positional relationship between the door lock device 4 and the opening 212 along the front-rear direction of the vehicle is one of the front side and the rear side of the vehicle at the opening 212. For example, when the door lock device 4 is provided on the side of the side door body 2 on the rear side of the vehicle, the location of the door lock device 4 may be on the rear side of the vehicle at the opening 212. When the door lock device 4 is provided on the front side of the vehicle in the side door body 2, the location of the door lock device 4 may be the front side of the vehicle in the opening 212. In the present example, the location of the door lock device 4 is the rear side of the vehicle in the side door body 2 and the rear side of the vehicle in the opening 212.

[Deformation induction part]
The deformation inducing portion 5 causes the housing portion 31 and the opening edge 213 of the facing area 211 to come into contact with each other due to the deformation of the door trim 3 caused by an external force from the front side or the rear side of the vehicle, so that the facing area 211 is removed from the door lock device 4. Transform to separate. The deformation inducing section 5 is provided on at least one of the door trim 3 and the door inner panel 21. The deformation inducing portion 5 may include, for example, at least one of the stop portion 51 and the bent portion 52. The deformation inducing section 5 of this example is composed of only the stopper portion 51, but may be composed of only the bent portion 52, or may be composed of both of the stopper portion 51 and the bent portion 52. Good.

(Stop part)
The stopper 51 restricts the movement of the opening edge 213 of the facing area 211 toward the vehicle outer side by the contact between the housing portion 31 and the opening edge 213 of the facing area 211 (FIG. 2). Due to this contact, the stopper 51 may bend the facing area 211 so as to be convex inward of the vehicle. The stopper 51 projects from the outer surface of the vehicle in the housing 31 of the door trim 3 so as to extend between the door inner panel 21 and the door outer panel. The protruding direction of the stopper 51 is the direction behind the vehicle and toward the outside of the vehicle with respect to the line along the vehicle width direction. The opening edge 213 of the facing area 211 is abutted against the stopper 51. Thereby, the facing area 211 can be easily deformed so as to be separated from the door lock device 4.

It is preferable that the stop portion 51 is formed at a position where the housing portion 31 and the opening edge 213 of the facing region 211 come into contact with the opening edge 213 that comes into contact with the rear portion 32 when the housing portion 31 comes into contact with each other. That is, it is preferable that the stop portion 51 is formed on the vehicle exterior side of the accommodation portion 31 rather than the intersection of the extension line extending from the opening edge 213 in the vehicle length direction and the accommodation portion 31. Then, the opening edge 213 comes into contact with the rear portion 32 before the stopper portion 51 and slides along the rear portion 32 to the outside of the vehicle, so that the load in the vehicle inward direction with respect to the facing area 211 is increased. Is easy to operate. Furthermore, since the opening edge 213 is pressed against the stopper 51, it is easier to apply a load inward of the vehicle to the facing area 211. Therefore, the facing area 211 is easily deformed so as to be separated from the door lock device 4. The shape of the stop portion 51 is not particularly limited as long as the opening edge 213 can be stopped when the accommodation portion 31 and the opening edge 213 of the facing region 211 contact each other. The stopper 51 is composed of a linear piece that linearly protrudes from the outer surface of the housing 31.

(Bent part)
The bent portion 52 is locally provided in the front-rear direction of the facing area 211, and bends the facing area 211 so as to be convex inward of the vehicle (indicated by a chain double-dashed line in a dashed circle in FIG. 2 ). The bent portion 52 may be formed along the vertical direction of the facing area 211. The bent portion 52 may be formed of a thin portion, an uneven portion, a convex portion, or the like. The thin portion can be formed by a notch formed in at least one of the inner side and the outer side of the vehicle in the facing area 211. Examples of the cross-sectional shape of the notch include a V shape and a U shape. A thin-walled portion formed by a notch having a V-shaped cross-section formed on the inner side of the vehicle in the facing region 211 is shown in the broken line circle in FIG. Although illustration is omitted, the uneven portion may be configured such that the inside of the vehicle is convex and the outside of the vehicle on the opposite side is concave, for example. Although not shown, the convex portion may be formed by forming a protrusion such as a bead so as to protrude toward the inside of the vehicle. The number of bent portions 52 may be singular or plural.

[Behavior of facing area]
The behavior of the side door structure 1 of the present embodiment when an external force (indicated by a white arrow in FIG. 3) acts from the front side of the vehicle will be described mainly with reference to FIG. 3 (as needed, FIG. 2). FIG. 3 schematically shows the side door structure 1 when an external force acts from the front side of the vehicle.

When the door trim 3 and the door trim 3 are rearwardly deformed by an external force acting from the front due to a frontal collision or the like, the housing portion 31 of the door trim 3 is displaced rearward, and the housing portion 31 abuts the opening edge 213 of the facing area 211. At this time, the opening edge 213 of the facing area 211 and the rear portion 32 of the door trim 3 are in sliding contact with each other, and the opening edge 213 of the facing area 211 and the stopper 51 are in contact with each other. Then, the opening edge 213 of the facing area 211 is abutted against the stopper 51. At this time, the movement of the opening edge 213 of the facing area 211 to the outside of the vehicle is restricted, and a load inward of the vehicle acts on the facing area 211 so that the facing area 211 becomes convex toward the inside of the vehicle. To bend. The bending of the facing area 211 separates the facing area 211 from the door lock device 4.

With reference to FIG. 4, the behavior when an external force (shown by a white arrow in FIG. 4) acts from the front side of the vehicle in the side door structure without the deformation inducing section 5 (FIG. 2) will be described. FIG. 4 schematically shows a side door structure when an external force is applied from the front side of the vehicle. As shown in FIG. 4, when the accommodating portion 31 of the door trim 3 is displaced rearward and the accommodating portion 31 abuts the opening edge 213 of the facing region 211, the opening edge 213 is moved outward by the accommodating portion 31 as shown in FIG. By being displaced, the facing area 211 and the door lock device 4 come into contact with each other.

[Action effect]
The side door structure 1 according to the embodiment can have the following effects.

(1) Even if an external force such that the door trim 3 is deformed acts on the side door structure 1 from the front side of the vehicle, the door lock device 4 has a simple structure including the stopper portion 51 (deformation inducing portion 5). Can prevent damage. The stop portion 51 restricts the movement of the opening edge 213 in the facing area 211 of the door inner panel 21 toward the outside of the vehicle, and the facing area 211 is bent to be convex toward the inside of the vehicle. Therefore, the facing area 211 can be separated from the door lock device 4. Therefore, the contact between the facing area 211 and the door lock device 4 can be suppressed. Therefore, the side door body 2 can be unlocked.

(2) An increase in weight, an increase in cost, and a decrease in productivity hardly occur. Since the door lock device 4 can be prevented from being damaged by a simple structure including the stopper portion 51 (deformation inducing portion 5), the door inner panel 21 is increased in order to increase the rigidity of the door inner panel 21 so that the door trim 3 is not deformed. This is because it is not necessary to increase the plate thickness of or to separately provide a reinforcing material on the door inner panel 21.

The present invention is not limited to these examples, but is defined by the claims, and is intended to include meanings equivalent to the claims and all modifications within the scope. For example, the rear slide type side door body may be configured by the side door of the present invention. This configuration corresponds to a state in which the directions of “FR” and “RR” are reversed and the directions of “RH(OUT)” and “LH(IN)” are reversed in FIGS. 2 and 3. In this case, even if an external force such that the door trim is deformed due to a rear surface collision or the like acts from the rear side, damage to the door lock device can be prevented.
