SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle slope door structure capable of increasing the space inside the vehicle.

A vehicle slope door structure according to one aspect of the present invention includes a first door rotatably attached to a lower portion of a vehicle body of a vehicle via a first hinge, and a front end portion of the first door via a second hinge. and a second door rotatably attached to the second door, wherein the first door and the second door are arranged side by side in a direction perpendicular to the vertical direction of the vehicle when the first door and the second door are closed. The second door is arranged closer to the interior of the vehicle than the first door when the first door and the second door are closed, and the first door is located when the first door and the second door are closed. and a first slope panel having a first slope surface which is fixed to the outer panel and is stepped on by an object who enters and exits the vehicle when the first door and the second door are open. and the second door includes an inner panel that forms an interior trim in the vehicle interior when the first door and the second door are closed, and is fixed to the inner panel, and the first door and the second door are fixed to the inner panel. and a second slope panel having a second slope surface to be stepped on by an object to get in and out of the vehicle on the opposite side of the vehicle from the first door in an open state, wherein the first slope surface and the second slope surface are the first door and the second slope surface. 2 facing each other in the closed state.

In such a slope door structure, the first door has a first slope panel having a first slope surface that is stepped on by an object to get on and off, and the second door has a second slope panel that has a second slope surface to be stepped on by an object to get on and off. It has a slope panel. When the first door and the second door are closed (normal state), the first door and the second door are arranged in the vertical direction of the vehicle so that the second door is arranged closer to the interior of the vehicle than the first door. The first slope panel and the second slope panel are arranged side by side in a direction perpendicular to the vehicle and are accommodated in the passenger compartment of the vehicle. When opening the first door and the second door and using the first slope panel and the second slope panel, rotate the first door to the opposite side of the vehicle and rotate the second door to the opposite side of the vehicle. move. Thus, the first slope panel is configured as part of the first door and the second slope panel is configured as part of the second door. That is, the first slope panel and the second slope panel are integrated with the slope door. Therefore, the width dimension of the door unit including the door and the slope in the normal state is smaller than when the door and the slope are configured separately. This increases the space inside the vehicle.

Further, when the first door and the second door are 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 side and the first door is moved toward the vehicle side. Rotate. At this time, since the first slope surface of the first slope panel and the second slope surface of the second slope panel face each other, the first slope surface and the second slope surface are not exposed inside the vehicle compartment. Therefore, it is possible to prevent a passenger or the like from touching the first slope surface and the second slope surface and getting dirty.

The second door has a shape that tapers toward the tip of the second door, and a leg that contacts the ground when the first door and the second door are open is attached to the tip of the inner panel. The leg portion may be arranged on the exterior side of the vehicle with respect to the innermost portion of the inner panel, when the first door and the second door are closed.

With such a configuration, the inner panel does not come into direct contact with the ground, so the inner panel is prevented from coming into contact with the ground and becoming dirty. In addition, when the first door and the second door are closed, the legs are prevented from protruding further into the vehicle interior than the inner panel. Therefore, even if the leg portion is attached to the inner panel, the width dimension of the door unit including the door and the slope in the normal state is reduced, thereby increasing the space inside the vehicle compartment.

The slope door structure further comprises a slope member which is provided so as to be freely deployable with respect to the second door and which is stepped on by the object to get on and off on the opposite side of the vehicle from the second door when the first door and the second door are open, The slope member is disposed between the first door and the second door when the first door and the second door are closed, and the first slope surface and the second slope surface extend from the first door and the second door. may face each other across the slope member in the closed state.

In such a configuration, when the first door and the second door are opened and the first slope panel, the second slope panel and the slope member are used, the first door and the second door are rotated to the opposite side of the vehicle. At the same time, the slope member is deployed on the opposite side of the vehicle with respect to the second door. The use of three units, the first door, the second door and the ramp member in this way, increases the length dimension of the ramp door structure when the first ramp panel, the second ramp panel and the ramp member are used, or The height dimension of the slope door structure in the normal state can be reduced. Further, when the first door and the second door are closed and the first slope panel, the second slope panel and the slope member are accommodated in the passenger compartment, the slope member is overlapped with the second door and the second door and the second door are stored. The first door is rotated toward the vehicle. At this time, since the first slope surface of the first slope panel and the second slope surface of the second slope panel face each other across the slope member, the first slope surface, the second slope surface and the slope member are exposed to the inside of the passenger compartment. never do. Therefore, it is possible to prevent the occupants from touching the first slope surface, the second slope surface and the slope member and getting dirty.

The slope member may be slidably attached to the second door. In such a configuration, when the first door and the second door are opened and the first slope panel, the second slope panel and the slope member are used, the first door and the second door are rotated to the opposite side of the vehicle. After that, the slope member is slid so as to be deployed on the opposite side of the vehicle with respect to the second door. When closing the first door and the second door and storing the first slope panel, the second slope panel and the slope member in the vehicle compartment, the slope member is slid toward the vehicle side so as to overlap the second door. After that, the second door and the first door are rotated toward the vehicle. With such a simple structure, the slope member can be deployed with respect to the second door.

The vehicle body may have a frame member arranged under the vehicle, and the first door may be rotatably attached to the frame member via a first hinge. In such a configuration, since the first door is attached to the frame member, the attachment strength of the first door is increased.

ADVANTAGE OF THE INVENTION According to this invention, the space in a vehicle interior can be expanded.

The door inner 15 has an inner panel 20, a slope panel 21 (second slope panel) fixed to the inner panel 20, and a slope reinforcement 22 disposed between the inner panel 20 and the slope panel 21. ing.

The inner panel 20 constitutes a part of the interior trim of the interior of the vehicle 1 . For this reason, the inner panel 20 is exposed in the vehicle interior and becomes a member that is visible to the passengers. Therefore, the inner panel 20 is made of iron, aluminum, resin, or the like having a color that is in harmony with other interior parts.

The slope panel 21 is provided on the rear side of the door outer 13 (opposite side of the vehicle 1) for the object to step on when the object gets on and off the vehicle 1 with the slope door 10 open with respect to the vehicle body 2. It has a slope surface 21a (second slope surface) that The slope surface 21a becomes the upper surface of the slope panel 21 when getting on and off. The slope reinforcement 22 is a member that reinforces the slope panel 21 . The slope panel 21 is made of iron, aluminum, resin, or the like. The slope reinforcement 22 is made of iron or the like.

The door inner 15 has a shape that tapers toward the tip of the door inner 15 . That is, the thickness of the door inner 15 gradually decreases toward the tip of the door inner 15 . A leg 23 is attached to the tip of the inner panel 20 and contacts the ground S when the slope door 10 is open. Therefore, the inner panel 20 does not come into direct contact with the ground S. The leg portion 23 is arranged on the exterior side of the vehicle 1 with respect to the portion 20a of the inner panel 20 that is positioned closest to the interior side of the vehicle interior when the slope door 10 is closed.

The door outer 13 and the door inner 15 are arranged side by side in the longitudinal direction (X direction) of the vehicle 1 so as to stand when the slope door 10 is closed with respect to the vehicle body 2, as shown in FIG. A state in which the slope door 10 is closed is a normal state in which the vehicle 1 can travel. The longitudinal direction of the vehicle 1 is a direction perpendicular to the vertical direction (Z direction) of the vehicle 1 . When the slope door 10 is closed, the door inner 15 is arranged on the front side (vehicle interior side) of the door outer 13 . At this time, the door outer 13 and the door inner 15 are arranged so as to stand perpendicular to each other with respect to the floor panel 6 .

When the slope door 10 is closed, the lock mechanism 24 holds the door outer 13 and the door inner 15 upright. The lock mechanism 24 is a mechanism that locks the slope door 10 and the vehicle body 2 . Although not shown, the lock mechanism 24 includes, for example, a striker provided on the outer door 13 and a lock member provided on the vehicle body 2 and engaged with the striker when the outer door 13 and the inner door 15 are in an upright state. ing.

Moreover, the slope panels 18 and 21 are accommodated in the vehicle interior of the vehicle 1 when the slope door 10 is closed. At this time, the outer panel 17 is positioned at the rearmost side of the slope door 10 and the inner panel 20 is positioned at the frontmost side of the slope door 10 . The slope surface 18a of the slope panel 18 and the slope surface 21a of the slope panel 21 directly face each other. Note that the slope surfaces 18a and 21a may be in contact with each other or may be separated from each other.

As shown in FIG. 3 , when the slope door 10 is open, the door inner 15 is arranged behind the door outer 13 by being unfolded with respect to the door outer 13 . At this time, the slope panel 18 is positioned above the outer panel 17 in the door outer 13 . In the door inner 15, the slope panel 21 is positioned above the inner panel 20. - 特許庁That is, the slope surface 18a of the slope panel 18 and the slope surface 21a of the slope panel 21 face upward. An inclined surface inclined at a predetermined angle from the vehicle body 2 toward the ground S is formed by the slope surfaces 18a and 21a.

When using the slope panels 18 and 21 in the back door 8 configured as described above, the door hatch 9 and the slope door 10 are opened as shown in FIG. When opening the slope door 10 from the normal state shown in FIG. 2, the lock between the slope door 10 and the vehicle body 2 by the lock mechanism 24 is first released. Then, the door inner 15 is unfolded with respect to the door outer 13 by rotating the door outer 13 rearward and rotating the door inner 15 rearward in this state.

On the other hand, when closing the slope door 10 from the opened state shown in FIG. 3, the door inner 15 is rotated forward to fold the door inner 15 with respect to the door outer 13, and the door outer 13 is rotated forward in this state. . Then, the lock mechanism 24 locks the slope door 10 and the vehicle body 2 .

FIG. 4 is a side sectional view showing a vehicle equipped with a back door as a comparative example. In FIG. 4 , the vehicle 1 includes a back door 50 and a slope 51 arranged in front of the back door 50 (inside the passenger compartment).

The back door 50 has a door outer 52 , a door inner 53 arranged in front of the door outer 52 , and a door hatch 54 arranged above the door outer 52 . The door outer 52 is fixed to the door inner 53 and door hatch 54 . A trim 55 is arranged on the front side of the door inner 53 .

The slope 51 has a base slope 56 rotatably connected to the floor panel 6 of the vehicle body 2 and a slide slope 57 slidably connected to the base slope 56 . The base slope 56 has a slope surface 56a, and the slide slope 57 has a slope surface 57a. When the slope 51 is accommodated in the vehicle compartment, the base slope 56 is rotated forward while the slide slope 57 is slid forward and overlapped on the base slope 56 .

However, when the slope 51 is accommodated in the vehicle compartment, the width dimension W of the back door unit including the back door 50 and the slope 51 is increased because the slope 51 is arranged across the back door 50 . For this reason, the space (space) in the vehicle interior becomes narrow. Further, when the slope 51 is accommodated in the vehicle interior, the slope surface 57a of the slide slope 57 that is stepped on by the object to get on and off is exposed in the vehicle interior. As a result, not only does the appearance of the slope 51 deteriorate, but the slope surface 57a may be soiled by a passenger or the like who touches the slope surface 57a.

In order to solve such problems, in the present embodiment, the door outer 13 has a slope panel 18 having a slope surface 18a that is stepped on by the object to get on and off, and the door inner 15 has a slope panel 18 that has a slope surface 21a to be stepped on by the object to get on and off. 21. When the door outer 13 and the door inner 15 are closed (normal state), the door outer 13 and the door inner 15 are arranged side by side in the longitudinal direction of the vehicle 1 so that the door inner 15 is arranged closer to the interior of the vehicle 1 than the door outer 13 is. At the same time, the slope panels 18 and 21 are accommodated in the vehicle interior of the vehicle 1. When the outer door 13 and the inner door 15 are opened and the slope panels 18 and 21 are used, the outer door 13 is rotated to the opposite side of the vehicle 1 and the inner door 15 is rotated to the opposite side of the vehicle 1.例文帳に追加Thus, the slope panel 18 is configured as part of the door outer 13 and the slope panel 21 is configured as part of the door inner 15 . That is, the slope panels 18 and 21 are configured integrally with the slope door 10 . Therefore, the width W (see FIG. 2) of the back door unit including the back door and the slope in the normal state is larger than in the case where the back door 50 and the slope 51 are configured separately as in the above comparative example. become smaller. This increases the space inside the vehicle.

When the door outer 13 and the door inner 15 are closed and the slope panels 18 and 21 are accommodated in the vehicle interior, the door inner 15 is rotated toward the vehicle 1 and the door outer 13 is rotated toward the vehicle 1 . At this time, since the slope surface 18a of the slope panel 18 and the slope surface 21a of the slope panel 21 face each other, the slope surfaces 18a and 21a are not exposed in the passenger compartment. Therefore, it is possible to prevent the occupants from touching the slope surfaces 18a and 21a and soiling them.

Moreover, since the slope panels 18 and 21 are configured as part of the slope door 10, the number of parts of the back door unit can be reduced. Therefore, it is possible to reduce the cost and reduce the size and weight of the back door unit.

Further, in this embodiment, a leg portion 23 is attached to the tip portion of the inner panel 20 so as to contact the ground S when the door outer 13 and the door inner 15 are open. Therefore, since the inner panel 20 does not directly contact the ground S, the inner panel 20 is prevented from contacting the ground S and becoming dirty. Therefore, the occupants do not have to worry about dirt when the door outer 13 and the door inner 15 are closed. Further, the leg portion 23 is arranged on the exterior side of the vehicle 1 with respect to the innermost portion 20a of the inner panel 20 when the door outer 13 and the door inner 15 are closed. Therefore, when the door outer 13 and the door inner 15 are closed, the leg portion 23 is prevented from protruding further into the vehicle interior than the inner panel 20 . Therefore, even if the leg portion 23 is attached to the inner panel 20, the width dimension of the door unit including the door and the slope in the normal state is reduced, thereby increasing the space inside the vehicle compartment.

Further, in this embodiment, since the door outer 13 is rotatably attached to the lower back 16 via the hinge 12, the mounting strength of the door outer 13 is increased.

FIG. 5 is a side sectional view showing a closed state of a back door including a vehicle slope door structure according to a second embodiment of the present invention. FIG. 6 is a side cross-sectional view showing a state in which the back door shown in FIG. 5 is opened.

5 and 6, the back door 8 has a slope door unit 35. As shown in FIG. The slope door unit 35 constitutes the slope door structure of this embodiment. The slope door unit 35 includes a slope door 30 and a flat plate-like slope member 32 attached to the slope door 30. - 特許庁

The slope door 30 has the above door outer 13 and a door inner 31 (second door) rotatably attached to the door outer 13 via a hinge 14 . The door inner 31 has an inner panel 20, a slope panel 21 and a slope reinforcement 22, like the door inner 15 in the first embodiment.

At the tip of the slope panel 21 , a rectangular tube-shaped guide portion 33 that guides the slope member 32 in the longitudinal direction of the vehicle 1 is provided. Instead of providing the guide portion 33 on the slope panel 21, the slope panel 21 may be provided with a guide groove extending in the longitudinal direction of the vehicle 1, and the slope member 32 may be provided with a guide protrusion that engages with this guide groove. The door inner 31 may or may not have the leg portion 23 described above.

The slope member 32 is attached to the door inner 31 so as to be slidable in the longitudinal direction of the vehicle 1 . The longitudinal direction of the vehicle 1 corresponds to the parallel direction of the door outer 13 and the door inner 31 when the slope door 30 is open. That is, the slope member 32 is provided so as to be unfoldable by sliding with respect to the door inner 31 . The slope member 32 has a slope surface 32a that is stepped on by the object on the rear side of the door inner 31 (opposite side of the vehicle 1) when the object gets on and off the vehicle 1 with the slope door 30 open. have. The slope surface 32a becomes the upper surface of the slope member 32 when getting on and off.

As shown in FIG. 5, the slope member 32 is arranged between the door outer 31 and the door inner 31 when the slope door 30 is closed. The slope surface 18a of the slope panel 18 and the slope surface 21a of the slope panel 21 face each other with the slope member 32 interposed therebetween. At this time, for example, frictional force generated between the slope member 32 and the guide portion 33 prevents the slope member 32 from lowering due to gravity.

As shown in FIG. 6 , when the slope door 30 is open, the door inner 31 is arranged behind the door outer 13 by unfolding with respect to the door outer 13 . The slope member 32 is arranged on the rear side of the door inner 31 by being deployed with respect to the door inner 31 . At this time, the tip of the slope member 32 contacts the ground S. Therefore, the slope surfaces 18a and 21a of the slope panels 18 and 21 and the slope surface 32a of the slope member 32 form an inclined surface inclined from the vehicle body 2 toward the ground S at a predetermined angle.

As shown in FIG. 6, when opening the slope door 30, the door outer 13 is rotated rearward, and in this state, the door inner 31 is rotated rearward. expand against. By sliding the slope member 32 rearward in this state, the slope member 32 is unfolded with respect to the door inner 31 .

On the other hand, as shown in FIG. 5 , when closing the slope door 30 , the slope member 32 is slid forward to overlap the door inner 31 . By rotating the door inner 31 forward, the door inner 31 is folded with respect to the door outer 13, and in this state, the door outer 13 is rotated forward.

In this embodiment, when the outer door 13 and the inner door 31 are opened and the slope panels 18 and 21 and the slope member 32 are used, the outer door 13 and the inner door 31 are rotated to the opposite side of the vehicle 1, The slope member 32 is deployed on the opposite side of the vehicle 1 with respect to the door inner 31. - 特許庁By using the three units of the door outer 13, the door inner 31 and the slope member 32 in this manner, the length dimension (front-rear dimension) of the slope door unit 35 can be increased when the slope panels 18, 21 and the slope member 32 are used. Alternatively, the height dimension (vertical dimension) of the slope door unit 35 in the normal state can be reduced. Further, when the door outer 13 and the door inner 31 are closed and the slope panels 18 and 21 and the slope member 32 are stored in the vehicle interior, the slope member 32 is placed on the door inner 31 and the door inner 31 and the door outer 13 are placed on the vehicle 1 side. rotate to At this time, since the slope surface 18a of the slope panel 18 and the slope surface 21a of the slope panel 21 face each other with the slope member 32 interposed therebetween, the slope surfaces 18a and 21a and the slope member 32 are not exposed to the interior of the vehicle. Accordingly, the occupants and the like are prevented from touching the slope surfaces 18a and 21a and the slope member 32 and getting dirty.

Further, in this embodiment, when the outer door 13 and the inner door 31 are opened and the slope panels 18 and 21 and the slope member 32 are used, the outer door 13 and the inner door 31 are rotated to the opposite side of the vehicle 1, and then the slope is opened. The member 32 is slid so as to be deployed on the opposite side of the vehicle 1 with respect to the door inner 31. - 特許庁When the door outer 13 and the door inner 31 are closed and the slope panels 18 and 21 and the slope member 32 are accommodated in the vehicle compartment, the slope member 32 is slid toward the vehicle 1 so as to overlap the door inner 31, and then the door inner 31 is closed. And the door outer 13 is rotated toward the vehicle 1 side. With such a simple structure, the slope member 32 can be deployed with respect to the door inner 31 .

In this embodiment, the slope member 32 is attached to the door inner 13 so as to be slidable in the front-rear direction. It may be rotatably attached.

Also, in the present embodiment, the slope door unit 35 has one slope member 32, but the number of slope members is not particularly limited to one, and may be two or more. That is, the slope door unit may be composed of four or more units.

Although some embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. For example, in the above-described embodiment, the door outer 13 is rotatably attached to the lower back 16, which is a frame member, via the hinge 12, but the configuration is not particularly limited. The door outer 13 may be rotatably attached via a hinge 12 to a bumper reinforcement (not shown) that reinforces the rear bumper 7, for example, or is rotatably attached to the floor panel 6 via a hinge 12. may
