By the way, in the conventional technology described above, the base slope and the slide slope of the slope device are made of thin plates and do not have the function of absorbing the impact of a vehicle collision. Such a configuration is disadvantageous against collision with the vehicle, and it is difficult to absorb the impact that occurs when the vehicle collides. Therefore, there is another door on the outside of the slope device for absorbing the impact when the vehicle collides.

SUMMARY OF THE INVENTION An object of the present invention is to provide a slope door structure for a vehicle that can easily absorb the impact generated when the vehicle collides.

A slope door structure for a vehicle according to one aspect of the present invention includes a slope door rotatably attached to a lower portion of a vehicle body of a vehicle via a hinge portion, the slope door including a door panel and a door panel fixed to the vehicle body. A slope panel that is stepped on by an object who gets in and out of the vehicle when the door is open, and a strength member that is placed between the door panel and the slope panel and receives a collision load on the vehicle. , are connected to the strength members.

In such a slope door structure, when the slope door is closed (normal state), the slope panel is housed inside the vehicle compartment. When the vehicle collides in such a normal state, the strength member arranged between the door panel and the slope panel receives the collision load. At this time, since the strength member is connected to the hinge portion, the collision load is transmitted from the strength member to the vehicle body via the hinge portion. This makes it easier to absorb the impact that occurs when the vehicle collides.

The slope door includes a first door rotatably attached to the lower portion of the vehicle body via a hinge portion, and a second door provided so as to be unfoldable with respect to the first door. a first door panel and a first slope panel fixed to the first door panel and stepped on by an object to get on and off when the slope door is open; a second door is fixed to the second door panel and the slope; and a second slope panel to be stepped on by the object to get on and off when the door is open, and the strength member may be arranged between the first door panel and the first slope panel.

In such a configuration, when the first slope panel and the second slope panel are used by opening the slope door, the first door is rotated to the opposite side of the vehicle and the second door is moved to the first door. Deploy on opposite side of vehicle. When the slope door is closed and the first slope panel and the second slope panel are accommodated in the vehicle interior, the second door is overlapped with the first door and the first door is rotated toward the vehicle. Since there are two doors such as the first door and the second door, the length dimension of the slope door structure is increased when the first slope panel and the second slope panel are used, or the slope in the normal state The height dimension of the door structure can be reduced.

The first door is rotatably attached to the lower portion of the vehicle body via a first hinge portion, the first hinge portion is connected to the strength member, and the second door is attached to the tip portion of the first door. The first slope panel and the second slope panel are rotatably attached via a second hinge portion and arranged closer to the interior of the vehicle than the first door when the slope door is closed. , may face each other when the slope door is closed.

In such a configuration, when the slope door is opened to use the first slope panel and the second slope panel, the first door is rotated to the opposite side of the vehicle and the second door is rotated to the opposite side of the vehicle. move. When the slope door is closed and the first slope panel and the second slope panel are accommodated in the vehicle interior, the second door is rotated toward the vehicle and the first door is rotated toward the vehicle. When the first slope panel and the second slope panel are accommodated in the vehicle interior, the first slope panel and the second slope panel are exposed to the interior of the vehicle because the first slope panel and the second slope panel face each other. never do. Therefore, it is possible to prevent the passenger from touching the first slope panel and the second slope panel and getting dirty.

The slope door structure may further include a striker attached to one of the slope door and the vehicle body, and a lock member attached to the other of the slope door and the vehicle body and engaged with the striker to lock the slope door and the vehicle body. good.

With such a configuration, the collision load received by the strength member is transmitted not only to the vehicle body via the hinge portion, but also to the vehicle body via the striker and the lock member. Therefore, it becomes easier to absorb the impact that occurs when the vehicle collides.

The strength member may have a frame shape, and the hinge portion may be integrated with the strength member. With such a configuration, the rigidity of the strength member is increased, so that the shock generated when the vehicle collides can be absorbed more easily.

A frame member may be connected to the lower portion of the vehicle body, and the slope door may be rotatably attached to the frame member via a hinge portion. With such a configuration, the collision load received by the strength member is transmitted to the vehicle body via the hinge portion and the frame member. Therefore, it becomes easier to absorb the impact that occurs when the vehicle collides.
