Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are designated by the same reference numerals, and duplicate description will be omitted.

As shown in FIG. 1, the vehicle 1 includes a vehicle body 2. The arrow FR in the figure indicates the front side in the front-rear direction of the vehicle body 2, the arrow UP in the figure indicates the upper side in the vertical direction of the vehicle body 2, and the arrow OUT in the figure indicates the left-right direction (vehicle width direction) of the vehicle body 2. ) Indicates the outside.

The vehicle body 2 has a roof panel 3 and a pair of side panels 4 arranged on both left and right sides of the roof panel 3. The roof panel 3 is provided on the upper part of the vehicle body 2. The side panel 4 is provided on the side portion of the vehicle body 2. A bumper 5 is provided at the lower part of the rear end of the vehicle body 2. A spoiler 6 is provided at the upper part of the rear end of the vehicle body 2.

As shown in FIG. 2, an opening 2a is provided at the rear end portion of the vehicle body 2. The opening 2a is defined by the rear end of the roof panel 3, the rear end of the pair of side panels 4, and the upper end of the bumper 5.

The vehicle 1 includes an openable back door 7 that covers the opening 2a at the rear end of the vehicle body 2. The back door 7 is an opening / closing unit that can be raised and lowered with respect to the opening 2a. The back door 7 has a configuration in which the opening 2a is opened by moving from the lower side to the upper side of the vehicle 1 and the opening 2a is closed by moving from the upper side to the lower side of the vehicle 1. FIG. 1 shows a state in which the back door 7 is closed, and FIG. 2 shows a state in which the back door 7 is open. In the following description, the vertical direction with respect to the back door 7 is a direction in a state where the back door 7 is closed (see FIG. 1).

As shown in FIG. 3, the back door 7 includes a plurality of slats 8 arranged along the vertical direction of the vehicle body 2, guide rollers 9a and 9b, and a lean forcement 10.

Each slat 8 extends in the vehicle width direction. The slat 8 located at the lowermost side is provided with a handle 11 for opening and closing the back door 7. The slats 8 are made of a transparent resin having impact resistance. Examples of such a transparent resin include polycarbonate and acrylic resin. The slats 8 have an outer surface 8a and an inner surface 8b. In this embodiment, the outer surface 8a and the inner surface 8b are substantially flat surfaces. Adjacent slats 8 are joined by a joining portion 15 (see FIG. 1).

Of the plurality of slats 8, two or more slats 8 have a curved shape in the extending direction of the elevating guide rail 20. In the present embodiment, each of the slats 8 is curved with a constant curvature from one end to the other end of the elevating guide rail 20 in the extending direction. That is, in the present embodiment, the curvature of the slat 8 at a predetermined position and the mean curvature of the slat 8 are the same. The curvature of the slat 8 (radius of curvature R) is appropriately set according to the shape of the vehicle body 2.

In the back door 7, the curvature of one slat 8 and the curvature of the other slat 8 are different among the plurality of curved slat 8. That is, the back door 7 is configured to include a plurality of slats 8 having different curvatures. In the back door 7, in two adjacent slats 8, the curvature of the upper slat 8 is equal to or greater than the curvature of the lower slat 8. In other words, the radius of curvature of the upper slat 8 is less than or equal to the radius of curvature of the lower slat 8. In the back door 7, the curvature of the slat 8 located on the uppermost side is the largest, and the curvature of the other slat 8 is smaller than the curvature of the slat 8 located on the uppermost side. In the plurality of slats 8 other than the slat 8 located on the uppermost side, the curvature may be smaller than the curvature of the slat 8 adjacent to the upper side, or the curvature may be the same as the curvature of the slat 8 adjacent to the upper side. ..

For example, as shown in FIG. 4, when the back door 7 is configured to include five slats 8, the curvature of the _first slats 8 (81) located at the top is the other slats. It is larger than the curvature of 8 ( _{82, 8 3 ,} 8 ₄ , 8 ₅ ). In the slat 8 (82, 8 ₃ , _{8 4} , 85), the slat 8 ₂ and the slat _{8 3 may} have different curvatures or may have the same curvature. In the slats 8 ₂ and the slats 8 ₃ , the curvature of the slats 8 ₃ may be equal to or less than the curvature of the slats 8 ₂ .

As shown in FIG. 5, when the radius of curvature R1 of the slat 81 and the radius of curvature R2 of the slat 8 ₂ satisfy the relationship of the radius of curvature R1 <the radius of curvature _R2 , the slat 8 along the elevating guide rail 20 In the movement path of, the outer surface 8a of the slat 8 ₂ is not located outside the trajectory on which the outer surface 8a of the slat 8 ₁ moves. Specifically, as shown in FIG. 5, when the slat 8 ₂ moves in the opening direction and passes through the position of the slat 81, the trajectory on which the outer surface 8 _a of the slat 8 ₂ moves is the slat 8 ₁ . The outer surface 8a is inside the vehicle 1 with respect to the moving track.

The guide rollers 9a and 9b move along the elevating guide rail 20. The guide rollers 9a and 9b are rotatably supported at the end of the lean forcement 10 in the extending direction. The guide rollers 9a and 9b are arranged between the adjacent slats 8 and the slats 8. That is, the guide rollers 9a and 9b are arranged at the joint portion 15 between the adjacent slats 8. The diameters of the guide rollers 9a and 9b are formed to be larger than the thickness of the slats 8 and the lean forcement 10.

The lean forcement 10 is arranged so as to extend in the vehicle width direction. The lean forcement 10 is formed of a rigid body such as carbon fiber reinforced plastic (CFRP), aluminum or iron. Guide rollers 9a and 9b are rotatably provided at both ends of the lean forcement 10. The lean forcement 10 is attached to the inner surface 8b of the end portion of the slat 8 facing the joint portion 15 to reinforce the end portion of the slat 8. The lean forcement 10 is attached to the slats 8 so that the adjacent slats 8 can be bent at the joint portion 15. The slat 8 is supported by the elevating guide rail 20 via the guide rollers 9a and 9b at the end in the direction in which the back door 7 opens and the end in the direction in which the back door 7 closes.

An elevating guide rail 20 that slidably guides the back door 7 in the vertical direction of the vehicle body 2 is attached to the rear end portion of each side panel 4. That is, the vehicle 1 includes a pair of elevating guide rails 20 arranged so as to extend in the vertical direction of the vehicle body 2 with the opening 2a provided at the rear end of the vehicle body 2 interposed therebetween. The elevating guide rail 20 is formed in a U-shape in cross section, and is arranged so that the open side faces the opening 2a side. The elevating guide rail 20 has a shape along the outer surface 8a of the plurality of slats 8 when the back door 7 is closed.

In the back door 7 described above, the slats 8 are arranged along the extending direction of the elevating guide rail 20. The lean forcement 10 extends in the opposite direction of the pair of elevating guide rails 20.

The elevating guide rail 20 is provided with an accommodating portion 21 on which the guide rollers 9a and 9b of the back door 7 travel. As shown in FIG. 3, when the guide rollers 9a and 9b of the back door 7 are arranged in the accommodating portion 21, the end portion of the slats 8 in the vehicle width direction is arranged in the elevating guide rail. Further, a side seal (seal member) 22 for sealing the back door 7 is attached to the inner surface of the end portion of the elevating guide rail 20 on the outer side wall of the vehicle on the opening 2a side. The side seal 22 is made of an elastic material. The elevating guide rail 20 is formed with side walls on the outside and inside of the vehicle so that the back door 7 is parallel to the outer surface 8a and the inner surface 8b of the slat 8 located so as to fully close the opening 2a. The side seal 22 uniformly presses the outer surface 8a of the slat 8 in a state where the back door 7 is in contact with the slat 8 located so as to fully close the opening 2a. As a result, when the back door 7 is positioned so as to fully close the opening 2a, the adhesion between the side seal 22 and the slats 8 is ensured. The side seal 22 is arranged so as to sandwich the back door 7 inside the accommodating portion 21 in the vehicle width direction.

When the back door 7 opens and closes along the elevating guide rail 20, the guide rollers 9a and 9b travel on the accommodating portion 21.

Guide rails (not shown) that slidably guide the back door 7 in the front-rear direction of the vehicle body 2 are arranged on the lower surface side of both ends of the roof panel 3 in the vehicle width direction. That is, the vehicle 1 includes a pair of guide rails arranged so as to extend in the front-rear direction of the vehicle body 2. The guide rails may be continuously arranged on the elevating guide rail 20 or may be arranged at a slight distance from the elevating guide rail 20. The detailed description of the structure of the guide rail will be omitted.

In the opening / closing structure of the vehicle 1 as described above, when the back door 7 is fully closed as shown in FIG. 1, the back door 7 is locked by a lock mechanism (not shown). When the back door 7 is unlocked from that state and the back door 7 is raised by holding the handle 11, the back door 7 moves to the upper side of the vehicle body 2 along the elevating guide rail 20, and the back door 7 guides. It moves to the front side of the vehicle body 2 along the rail, and the back door 7 opens as shown in FIG.

When the back door 7 is lowered by holding the handle 11 from the state where the back door 7 is open, the back door 7 moves to the lower side of the vehicle body 2 along the elevating guide rail 20 and the back door 7 becomes the guide rail. Along the way, the vehicle moves to the rear side of the vehicle body 2, and the back door 7 closes.

As described above, in the opening / closing structure of the vehicle 1 according to the present embodiment, the curvature of one slat 8 and the curvature of the other slat 8 are different. Thereby, in the opening / closing structure of the vehicle 1, the back door 7 according to the shape of the vehicle 1 can be configured by setting the curvature of the slats 8 according to the shape of the vehicle 1. Therefore, in the opening / closing structure of the vehicle 1, the back door 7 can be provided in the vehicle 1 without impairing the design of the vehicle 1. As a result, the opening / closing structure of the vehicle 1 can be improved in design.

In the comparative example shown in FIG. 6, the radius of curvature R1 of the slat 81 and the radius of curvature _{R2 of the slat 8 2 satisfy} the relationship of the radius of curvature R1> the radius of curvature R2. That is, the curvature of the slat 8 ₁ is smaller than the curvature of the slat 8 ₂ . In this configuration, in the movement path of the slat 8 along the elevating guide rail 20, the outer surface 8a of the slat 8 ₂ is located outside the trajectory on which the outer surface 8a of the slat 8 ₁ moves. In this case, the distance between the outer surface 8a of the slat 8 ₂ and the side seal 22 becomes close, and the slat 8 ₂ presses the side seal 22. As a result, the contact of the side seal 22 becomes a load for the movement of the slats 82, and the movement of the back _door 7 is hindered.

In the opening / closing structure of the vehicle 1 according to the present embodiment, the back door 7 is configured to be opened by moving from the lower side to the upper side of the vehicle 1. The elevating guide rail 20 is provided with a side seal 22 that comes into contact with the outer surface 8a of the slats 8. In two adjacent slats 8, the slat 8 located above the moving direction of the slat 8 is the first slat (for example, the slat 8 ₁ in FIG. 5), and the slat 8 located below the moving direction is the second slat. (For example, in the case of the slat 8 ₂ in FIG. 5), in the movement path of the slat 8 along the elevating guide rail 20, the outer surface 8a of the second slat is the vehicle 1 rather than the track on which the outer surface 8a of the first slat moves. Not located outside of.

In this configuration, in a configuration in which the positional relationship between the first slat and the side seal 22 is defined in the closed state of the back door 7, the movement of the back door 7 causes the position of the first slat to be as shown in FIG. When the second slat is positioned, the outer surface 8a of the second slat is not located outside the vehicle 1 from the track on which the outer surface 8a of the first slat moves, so that the second slat does not press the side seal 22. Thereby, in the opening / closing structure of the vehicle 1, it is possible to prevent the movement of the back door 7 from being hindered by the excessive contact between the second slats and the side seal 22. Therefore, in the opening / closing structure of the vehicle 1, it is possible to avoid deterioration of the operability of the back door 7.

In the opening / closing structure of the vehicle 1 according to the present embodiment, each of the slats 8 is curved with a constant curvature from one end to the other end in the extending direction of the elevating guide rail 20. In this configuration, in the opening / closing structure of the vehicle 1, the curvature of the upper slat 8 is greater than or equal to the curvature of the lower slat 8 in the two adjacent slats 8. In this configuration, when the second slat is positioned at the position of the first slat due to the movement of the back door 7, the outer surface 8a of the second slat is located outside the vehicle 1 from the track on which the outer surface 8a of the first slat moves. It is possible to realize a configuration that does not.

Although the embodiments of the present invention have been described above, the present invention is not necessarily limited to the above-described embodiments, and various modifications can be made without departing from the gist thereof.

In the above embodiment, all the slat 8 included in the back door 7 have a curved shape, and the slat 8 located on the opening side from itself has a curvature equal to or greater than its own curvature and closes the opening 2a from itself. The configuration in which the slat 8 located on the directional side has a curvature equal to or less than its own curvature has been described as an example. However, a part of the slats 8 of the back door 7 may have a curved shape. For example, only a plurality of slats 8 arranged on the opening direction side of the opening 2a have a curved shape, and the slats 8 arranged on the closing direction side of the opening 2a are formed of non-curved flat plate-shaped slats 8. May be good. Further, in all the slat 8, the slat 8 located on the side in the direction of opening the opening 2a from itself has a curvature equal to or higher than its own curvature, and the slat 8 located on the side in the direction of closing the opening 2a from itself has a curvature equal to or less than its own. The configuration is provided with a curvature, but the curvature is not limited to this, and the curvature of the slat 8 located on the side in the direction of opening the opening 2a is larger than the curvature of the slat 8 located on the side in the direction of closing the opening 2a in two adjacent slats 8. It suffices to include a structure that is formed to be large. For example, the slat 8 arranged on the side in the direction of closing the opening 2a most is formed in a flat plate shape, and in the other slat 8, the curvature of the slat 8 located on the side in the direction of opening the opening 2a is the side in the direction of closing the opening 2a. The back door 7 may be configured to satisfy a configuration formed larger than the curvature of the slats 8 located at.

In the above embodiment, the embodiment in which the side seal 22 is provided so as to be in contact with the outer surface 8a of the slats 8 has been described as an example. However, the side seal 22 may be provided so as to be in contact with the inner surface 8b of the slats 8. In this configuration, in two adjacent slats 8, when the slat 8 located above the moving direction of the slat 8 is the first slat and the slat 8 located below the moving direction is the second slat, the elevating guide is used. In the movement path of the slat 8 along the rail 20, the inner surface 8b of the second slat is not located inside the vehicle 1 than the track on which the inner surface 8b of the first slat moves.

In this configuration, in a configuration in which the positional relationship between the first slat and the side seal 22 is defined in the closed state of the back door 7, when the second slat is positioned at the position of the first slat by the movement of the back door 7. Since the inner surface 8b of the second slat is not located inside the vehicle 1 with respect to the track on which the inner surface 8b of the first slat moves, the second slat does not press the side seal. This makes it possible to prevent the back door 7 from being hindered by excessive contact between the second slats and the side seals. Therefore, it is possible to avoid deterioration of the operability of the back door 7.

In the above embodiment, a mode in which the back door 7 slides on the elevating guide rail 20 by the guide rollers 9a and 9b has been described as an example. However, instead of the guide rollers 9a and 9b, the back door 7 may slide on the elevating guide rail 20 by a slide shoe.

In the above embodiment, the embodiment in which the outer surface 8a and the inner surface 8b of the slats 8 are substantially flat surfaces has been described as an example. However, the outer surface 8a and the inner surface 8b may be, for example, surfaces having irregularities. Further, in the above embodiment, a mode in which the slats 8 are curved (exhibiting a line-symmetrical shape) with a constant curvature from one end to the other end has been described as an example. However, the shape of the slat 8 is not limited to this, and the slat 8 may have an asymmetrical shape. In either configuration, the outer surface 8a of the second slat is not located outside the vehicle 1 than the track on which the outer surface 8a of the first slat moves in the movement path of the slat 8 along the elevating guide rail 20. Just do it. Alternatively, in the movement path of the slat 8 along the elevating guide rail 20, the inner surface 8b of the second slat may not be located inside the vehicle 1 than the track on which the inner surface 8b of the first slat moves. That is, the surface on the side where the side seal of the second slat is arranged is not located on the side where the side seal of the vehicle 1 is arranged on the track on which the surface on the side where the side seal of the first slat is arranged moves. It should be.

In the above embodiment, a mode in which the back door 7 (opening / closing unit) is provided behind the vehicle body 2 of the vehicle 1 has been described as an example. However, the opening / closing unit may be provided on the side of the vehicle body. Further, the back door 7 is opened by moving from the lower side to the upper side with respect to the opening 2a, but may be opened by moving from the upper side to the lower side, or may be opened by moving in the left-right direction. There may be.

Further, in the above embodiment, the embodiment in which the slats 8 are made of a transparent resin has been described as an example. However, the resin forming the slats 8 may be other than the transparent resin.
