Description

The present invention relates to an opening / closing structure of a vehicle.

As a conventional vehicle opening / closing structure, for example, the technique described in Patent Document 1 is known. The vehicle opening / closing structure described in Patent Document 1 includes a rear gate frame forming a peripheral portion of the rear gate, a retractable shutter that is slidably guided to the rear gate frame, and a winding portion that winds the shutter. .. The shutter has a structure in which a large number of slats are stacked one above the other and connected. Both sides of each slats are guided to the sides of the rear gate frame.

Japanese Unexamined Patent Publication No. 61-113122

In a vehicle, when the shutter is provided at the rear of the vehicle body, the slats are formed of a transparent resin in order to secure a rear view. Since resin slats have a larger linear expansion coefficient than steel plates and the like, the slats can expand and deform at high temperatures. Further, in the resin slats, the slats may shrink and deform at a low temperature. As described above, the resin slats may be deformed in response to changes in air temperature. Since the slats move along the guide rails, the position of the moving body connected to the slats with respect to the guide rails may change when the resin slats are deformed. This causes a problem in the movement of the moving body on the guide rail, and makes it difficult for the slats to move.

One aspect of the present invention is to provide an opening / closing structure for a vehicle that can avoid the occurrence of defects due to deformation of resin slats.

The vehicle opening / closing structure according to one aspect of the present invention is slidably guided by a pair of guide rails arranged so as to extend across an opening provided in the vehicle and an opening. The opening / closing unit comprises an opening / closing unit, and the opening / closing unit is moved in the opposite direction of the pair of guide rails by each of the plurality of resin slats arranged along the extending direction of the guide rails and the pair of guide rails. Is regulated, and a pair of moving bodies that are movably supported along the extending direction of the guide rail, a connecting member that connects the pair of moving bodies, and a slats that are arranged between the slats and the connecting members. It is provided with a rubber joining member for joining the connecting member and the connecting member.

In the opening / closing structure of the vehicle according to one aspect of the present invention, the slats and the connecting member are joined by a rubber joining member. As a result, in the opening / closing structure of the vehicle, when the slats expand at a high temperature, the joining member expands according to the expansion of the slats, so that the deformation of the slats is not transmitted to the connecting member. Further, in the opening / closing structure of the vehicle, when the slats contract at a low temperature, the joining member contracts according to the contraction of the slats, so that the deformation of the slats is not transmitted to the connecting member. Therefore, in the opening / closing structure of the vehicle, the deformation of the slats does not affect the connecting member and, by extension, the moving body. Therefore, in the opening / closing structure of the vehicle, it is possible to avoid a problem in the movement of the moving body due to a change in the position of the moving body. As a result, in the opening / closing structure of the vehicle, it is possible to avoid the occurrence of defects due to the deformation of the resin slats.

In one embodiment, the slat support comprises a slat support that movably supports the slat in the opposite direction of the pair of guide rails and is movably supported by each of the guide rails along the extending direction of the guide rails. The body may set the position of the slats in the direction opposite to the pair of guide rails and the direction orthogonal to the extending direction of the guide rails. In this configuration, the slats are slidably supported in the extending direction of the guide rails and supported by slide shoes that allow the slats to move in opposite directions. Therefore, the slats can be supported with respect to the guide rail without affecting the thermal expansion and contraction of the slats, and it is possible to suppress the displacement of the position of the slats with respect to the guide rail in the plate thickness direction.

In one embodiment, the moving body is a guide roller that moves along the extending direction of the guide rail, and the connecting member may rotatably support the guide roller. In this configuration, the deformation of the slats can be absorbed by the joining member, so that the deformation of the slats does not affect the position of the guide roller. Therefore, in the opening / closing structure of the vehicle, it is possible to avoid the occurrence of defects due to the deformation of the resin slats.

In one embodiment, a plurality of a pair of moving bodies, connecting members, and joining members may be provided at predetermined intervals in the extending direction of the guide rail. In this configuration, if deformation occurs in multiple slats, it can affect multiple moving objects. When the positions of a plurality of moving objects are changed, the operability of the opening / closing operation of the opening / closing unit may be further deteriorated. Therefore, in a configuration in which a plurality of moving bodies are provided, a configuration in which a joining member is provided is particularly effective.

In one embodiment, the joining member may extend in the opposite direction of the pair of guide rails. In this configuration, the joining member can appropriately absorb the deformation of the slats.

In one embodiment, a plurality of joining members may be arranged at predetermined intervals in the opposite direction of the pair of guide rails. In this configuration, the joining member can appropriately absorb the deformation of the slats.

According to one aspect of the present invention, it is possible to avoid the occurrence of defects due to deformation of the resin slats.

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. A curved portion 4a is provided at the rear end of the side panel 4. The region above the curved portion 4a in the opening 2a (hereinafter, the upper region of the opening 2a) has a shape that bends toward the front side of the vehicle body 2.

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 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 is movably supported by the elevating guide rail 20 in the extending direction of the elevating guide rail. 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 is joined to a plurality of slats 8 arranged along the vertical direction of the vehicle body 2, a positioning projection (moving body) 14, and a lean force (connecting member) 9. It includes a member 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. Slide shoes 12 as slat supports are attached to both ends of the slat 8 in the vehicle width direction. The slide shoe 12 is provided with a hole, and the slat 8 is movably sandwiched by fitting a part of the end portion of the slat 8 into the hole. The slats 8 are made of a transparent resin having impact resistance. Examples of such a transparent resin include polycarbonate and acrylic resin. Adjacent slats 8 are joined by a joining portion 15 (see FIG. 1).

The positioning protrusion 14 sets (positions) the position of the slats 8 with respect to the elevating guide rail 20. The elevating guide rail 20 restricts the positioning protrusion 14 from moving in the opposite direction of the elevating guide rail, and is supported by the elevating guide rail 20 so as to be movable along the extending direction of the elevating guide rail 20. The positioning protrusion 14 is housed in a protrusion accommodating portion 22 (described later) provided on the elevating guide rail 20. The positioning protrusion 14 is made of, for example, a resin. The positioning protrusion 14 has, for example, a cubic shape. A plurality of positioning protrusions 14 are provided in the extending direction of the elevating guide rail 20.

The lean forcement 9 is arranged so as to extend in the vehicle width direction. The lean forcement 9 is formed of a rigid body such as carbon fiber reinforced plastic (CFRP), aluminum or iron. As shown in FIG. 4, the cross section of the lean forcement 9 has a substantially U-shape. Specifically, the lean forcement 9 is erected perpendicularly to the base portion 9a at both ends of the plate-shaped base portion 9a extending in the vehicle width direction and the vertical end portions of the base portion 9a, and the vehicle width. It has side portions 9b and 9c extending in the direction. Both ends of the lean forcement 9 in the vehicle width direction are located inside the vehicle width direction of the slats 8 with both ends in the vehicle width direction. Positioning protrusions 14 are provided at both ends of the lean forcement 9.

The joining member 10 joins the slats 8 and the lean forcement 9. The joining member 10 extends in the vehicle width direction. The joining member 10 is made of sponge rubber. The cross section of the joining member 10 has, for example, a rectangular shape. The joining member 10 joins the slats 8 and the base portion 9a of the lean forcement 9. That is, the joining member 10 is not joined to the side portions 9b, 9c of the lean forcement 9, but is separated from the side portions 9b, 9c with a predetermined interval.

The position of the joining member 10, that is, the position of the lean forcement 9, is set to an arbitrary position of the slats 8. For example, the position of the joining member 10 is set in the center of the elevating guide rail 20 in the extending direction in the slat 8. The thickness of the joining member 10 (vertical dimension in FIG. 3) is appropriately set according to the linear expansion coefficient of the slats 8 and the like. The thickness of the joining member 10 is, for example, 5.0 mm.

In the back door 7 described above, the slats 8 are arranged along the extending direction of the elevating guide rail 20. The lean force 9 extends in the opposite direction of the pair of elevating guide rails 20.

The elevating guide rail 20 is provided with a shoe accommodating portion 21 that engages with the slide shoe 12 of the back door 7 and a protrusion accommodating portion 22 that engages with the positioning projection 14 of the back door 7. The protrusion accommodating portion 22 is arranged inside the shoe accommodating portion 21 in the vehicle width direction. Further, a side seal 23 for sealing the back door 7 is attached to the elevating guide rail 20. The side seal 23 is arranged so as to face the protrusion accommodating portion 22 with the back door 7 sandwiched inside the shoe accommodating portion 21 in the vehicle width direction.

When the back door 7 opens and closes along the elevating guide rail 20, the slide shoe 12 slides on the shoe accommodating portion 21 with the positioning projection 14 positioned on the projection accommodating portion 22.

Guide rails (not shown) that guide the back door 7 so as to be slidable in the front-rear direction of the vehicle body 2 are provided on the lower surface side of both ends of the roof panel 3 in the vehicle width direction and between the interior members (not shown). It is provided. 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 opened, the back door 7 is held in the open state due to the sliding resistance between the slide shoe 12 and the elevating guide rail 20.

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 slats 8 and the lean forcement 9 are joined by a rubber joining member 10. As a result, in the opening / closing structure of the vehicle 1, when the slat 8 expands at a high temperature, the joining member 10 expands in response to the expansion of the slat 8, so that the deformation of the slat 8 is not transmitted to the lean forcement 9. Further, in the opening / closing structure of the vehicle 1, when the slat 8 contracts at a low temperature, the joining member 10 contracts according to the contraction of the slat 8, so that the deformation of the slat 8 is not transmitted to the lean forcement 9. Therefore, in the opening / closing structure of the vehicle 1, the deformation of the slats 8 does not affect the lean force 9 and thus the positioning projection 14. Therefore, in the opening / closing structure of the vehicle 1, it is possible to avoid a problem in the movement of the positioning protrusion 14 due to a change in the position of the positioning protrusion 14. As a result, in the opening / closing structure of the vehicle 1, it is possible to avoid the occurrence of defects due to the deformation of the resin slats 8.

As shown in FIG. 5A, in the back door 7, when the slat 8 contracts at a low temperature (for example, −30 ° C.), the joining member 10 deforms according to the contraction of the slat 8, and the slat The joining member 10 absorbs the shrinkage of 8. As shown in FIG. 5B, in the back door 7, when the slat 8 expands at a high temperature (for example, 80 ° C.), the joining member 10 is deformed according to the expansion of the slat 8, and the slat 8 is deformed. The joining member 10 absorbs the expansion of the above. As described above, in the back door 7, the deformation of the slats 8 is not transmitted to the lean forcement 9. Therefore, in the opening / closing structure of the vehicle 1, it is possible to avoid the occurrence of defects due to the deformation of the resin slats 8.

In the conventional vehicle opening / closing structure, when the connecting member connecting the slats and the positioning protrusions is configured to be close to and separated from the positioning protrusions, the following problems may occur. When the slats contract, the connecting member moves away from the positioning projection. As a result, the position of the positioning protrusion does not change with respect to the elevating guide rail. However, when the slats move due to the contraction of the slats, the slats move with respect to the side seals, so that the side seals may come off the slats. In this case, the sealing property cannot be ensured. Also, in order to avoid this problem, if the position of the side seal is set inside in the vehicle width direction so that the slats do not come off from the side seal, the distance between the pair of side seals becomes shorter, so the opening width becomes wider. It becomes smaller and the visibility behind it decreases.

In the opening / closing structure of the vehicle 1 according to the present embodiment, since the deformation of the slats 8 is not transmitted to the lean forcement 9, it is not necessary to adopt the above configuration. In the opening / closing structure of the vehicle 1, the positional relationship between the slat 8 and the lean force 9 is unlikely to change (the difference between the center position of the slat 8 and the center position of the lean force 9). Therefore, in the opening / closing structure of the vehicle 1, there are no problems such as the side seal 23 coming off the slats 8 and the rear visibility being lowered.

The opening / closing structure of the vehicle 1 according to the present embodiment supports the slats 8 so as to be movable in the opposite directions of the pair of elevating guide rails 20, and each of the elevating guide rails 20 moves along the extending direction of the elevating guide rails 20. A slide shoe 12 that is supported as possible is provided. The slide shoe 12 sets the position of the slats 8 in the direction opposite to the pair of elevating guide rails 20 and in the direction orthogonal to the extending direction of the elevating guide rails 20. In this configuration, the slat 8 is slidably supported in the extending direction of the elevating guide rail 20, and is supported by the slide shoe 12 that allows the slat 8 to move in the opposite direction of the elevating guide rail 20. Therefore, the slat 8 can be supported with respect to the elevating guide rail 20 without affecting the thermal expansion and contraction of the slat 8, and it is possible to suppress the displacement of the position of the slat 8 with respect to the elevating guide rail 20 in the plate thickness direction. ..

In the opening / closing structure of the vehicle 1 according to the present embodiment, a plurality of a pair of positioning protrusions 14 are provided at predetermined intervals in the extending direction of the elevating guide rail 20. In this configuration, if deformation occurs in the plurality of slats 8, the plurality of positioning protrusions 14 may be affected. If the positions of the plurality of positioning protrusions 14 are changed, the operability of the opening / closing operation of the back door 7 may be further deteriorated. Therefore, in the configuration in which a plurality of positioning protrusions 14 are provided, the configuration in which the joining member 10 is provided is particularly effective.

In the opening / closing structure of the vehicle 1 according to the present embodiment, the joining member 10 extends in the facing direction (vehicle width direction) of the pair of elevating guide rails 20. In this configuration, the joining member 10 can appropriately absorb the deformation of the slats 8.

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, the slide shoe 12 has been described as an example as the slat support. However, the slat support may be, for example, a roller or the like.

In the above embodiment, when the back door 7 opens and closes along the elevating guide rail 20, the slide shoe 12 slides on the shoe accommodating portion 21 with the positioning projection 14 positioned on the projection accommodating portion 22. Was explained as an example. However, the guide roller may move on the elevating guide rail 20.

As shown in FIG. 6, the back door 7A includes guide rollers (moving bodies) 30a and 30b, and a connecting member 32. The guide rollers 30a and 30b have the elevating guide rail 36 fixed to the side panel 4 via the bracket 38. A side seal 23A is attached to the side panel 4.

The connecting member 32 rotatably supports the guide rollers 30a and 30b. Specifically, the connecting member 32 rotatably supports the guide rollers 30a and 30b by the support shaft 34. The joining member 10 joins the slats 8 and the connecting member 32. Even in this configuration, when the slat 8 expands at a high temperature, the joining member 10 expands in response to the expansion of the slat 8, so that the deformation of the slat 8 is not transmitted to the connecting member 32. Further, when the slat 8 contracts at a low temperature, the joining member 10 contracts according to the contraction of the slat 8, so that the deformation of the slat 8 is not transmitted to the connecting member 32. Therefore, the deformation of the slat 8 does not affect the connecting member 32 and, by extension, the guide rollers 30a and 30b. Therefore, it is possible to avoid a problem in the movement of the guide rollers 30a and 30b due to a change in the positions of the guide rollers 30a and 30b. As a result, it is possible to avoid the occurrence of defects due to the deformation of the resin slats 8.

Further, in the back door 7A, a slide shoe may be further provided at the end portion of the slats 8 in the vehicle width direction. In this case, for example, the dimension of the slat 8 shown in FIG. 6 in the vehicle width direction can be increased, and the slide shoe can be provided outside the guide rollers 30a and 30b in the vehicle width direction.

In the above embodiment, a mode in which the back door 7 is manually opened and closed has been described as an example. However, the back door 7 may be in a form that is automatically opened and closed. In this case, it suffices to provide a drive unit for opening and closing the back door 7.

In the above embodiment, the embodiment in which the joining member 10 extends in the vehicle width direction has been described as an example. However, a plurality of joining members may be arranged at predetermined intervals in the vehicle width direction. That is, the joining member may be composed of a plurality of members.

In the above embodiment, the embodiment in which the elevating guide rail 20 is provided with the curved portion 20a corresponding to the curved portion 4a of the side panel 4 has been described as an example. However, the form is not particularly limited, and such a curved portion 20a may not be provided on the elevating guide rail 20.
