Description

  Embodiments described herein relate generally to a vehicle slide rail structure.

  Conventionally, a rail provided on the floor of a vehicle, a cap attached to an end of the rail, and a cap provided with an inclined surface that guides a fallen object that has dropped on the top wall of the rail in a direction away from the internal space of the rail, There is known a vehicular slide rail structure provided with (for example, see Patent Document 1).

JP 2013-189167 A

  In this type of vehicle slide rail structure, for example, it is beneficial if a new configuration is obtained in which a fallen object that has fallen into the internal space of the rail can easily come out of the rail.

  Then, one of the subjects of this invention is obtaining the slide rail structure for vehicles of the novel structure from which the fallen object which fell to the internal space of a rail tends to come out to the outer side of a rail, for example.

  The vehicle slide rail structure according to the embodiment of the present invention includes, for example, a bottom wall portion, two outer wall portions projecting upward from the both ends in the width direction of the bottom wall portion, and upper ends of the outer wall portions. And two first inner walls connected to the inner end in the width direction of the top and projecting downward in the vehicle, and intersecting the width direction and the vehicle vertical direction. A rail extending in one direction, a top wall portion attached to one end of the rail in the first direction from above and having a top surface and covering the top from above the vehicle; A projecting portion that projects downward between the inner wall portions, and an inclined surface that is provided on the projecting portion and is connected to the top surface and extends toward the other end in the first direction of the rail so as to approach the bottom wall portion. And a cap having. Therefore, for example, when an object falls into the internal space of the rail, the falling object can be guided to the top surface side of the cap by the inclined surface. Therefore, for example, a fallen object easily comes out of the rail.

  In the vehicle slide rail structure, for example, the cap has a protrusion that protrudes further downward from the protrusion from the protrusion, and the bottom wall is provided with a first opening into which the protrusion is inserted. It is done. Therefore, for example, the cap can be positioned and attached to the rail more easily, more smoothly, or more quickly by aligning the protrusion and the first opening.

  In the above-described vehicle slide rail structure, for example, the cap is located on each side of the protruding portion in the width direction, protrudes downward from the top wall portion of the vehicle, and has two attachment pieces provided with claws. Each of the two outer wall portions is provided with a second opening for engaging the claw from the outside in the width direction of the outer wall portion. Thus, for example, the rail can support the cap more firmly at a total of three locations, one location where the projection is supported by the first opening and two locations where the claw of the mounting piece is supported by the second opening. . Therefore, it becomes more difficult to remove from the state where the cap is attached to the rail.

  Further, in the vehicle slide rail structure, for example, the two attachment pieces and the protrusions are arranged along the width direction when viewed from above the vehicle. Therefore, for example, the attachment piece and the protrusion can be attached with a smaller force than in the case where the attachment piece and the protrusion are not aligned in the width direction as viewed from above the vehicle but shifted in the first direction. The attachment of the cap to the rail is easy to improve.

  In the above-described vehicle slide rail structure, for example, the bottom wall portion is provided with a recessed portion that is recessed toward the lower side of the vehicle and in contact with the protruding portion. Therefore, for example, falling objects that have fallen into the inner space of the rail are likely to gather in the recesses, and in some cases, the falling objects can be more easily put out of the rail using the inclined surface.

  In the vehicle slide rail structure, for example, the rail is positioned on the other end side in the first direction with respect to the two first inner wall portions, and is connected to the inner end in the width direction of the top portion. Two second inner wall portions projecting downward in the vehicle, the two second inner wall portions are located inward in the width direction with respect to the two first inner wall portions, and the projecting portion has the width The two second inner wall portions and the two guide wall portions arranged in the first direction are spaced apart from each other in the direction. Therefore, for example, the two guide wall portions suppress the occurrence of a step in the width direction between the cap and the two second inner wall portions, and as a result, fallen objects that fall between the two second inner wall portions, More smoothly out of the rail.

  As shown in FIG. 2, one top wall portion 23 a of the two end caps 23 covers the two top portions 22 s of the front support portion 43 of the lower rail 22 from above. The other top wall portion 23 a of the end cap 23 covers the two top portions 22 s of the rear support portion 43 of the lower rail 22 from above.

  Further, the top wall portion 23a is configured so that at least a part of the two second connecting portions 22e (top portions) on the intermediate portion side in the front-rear direction with respect to the notch 42 is upward in a state where the end cap 23 is attached to the lower rail 22. Cover from.

  As shown in FIGS. 9 and 11, the attachment piece 23c protrudes downward from the first portion 23a1 of the top wall portion 23a and extends in the front-rear direction. The two attachment pieces 23c are separated from each other in the width direction. The lower rail 22 is attached between the two attachment pieces 23c. The width between the two attachment pieces 23 c is substantially the same as or slightly larger than the width of the lower rail 22.

  Each attachment piece 23c is provided with a claw 23f. The claw 23f protrudes inward in the width direction from the lower end of the attachment piece 23c. The claw 23f has a hooking surface 23f1 facing upward. The hooking surface 23f1 contacts the upper edge of the opening 22y when the end cap 23 is attached to the lower rail 22.

  The protruding portion 23b includes, for example, an inclined portion 23d, a protrusion 23e, and a guide wall portion 23g. The protruding portion 23b protrudes downward from the top wall portion 23a. The projecting portion 23 b is inserted between the two inner wall portions 22 t of the lower rail 22.

  The guide wall portion 23g protrudes downward from the inner end portion of the first portion 23a1 of the top wall portion 23a and extends in the front-rear direction. The two guide wall portions 23g are separated from each other in the width direction. An inclined portion 23d is provided between the two guide wall portions 23g.

  As shown in FIGS. 8 and 11, the distance in the width direction between the two guide wall portions 23g is the same as the distance in the width direction between the two inner wall portions 22z. The two guide wall portions 23g are aligned with the two inner wall portions 22z in the front-rear direction in a state where the end cap 23 is mounted on the lower rail 22. Further, the surface facing the inner side in the width direction of the guide wall portion 23g and the surface facing the inner side in the width direction of the two inner wall portions 22z are aligned in the front-rear direction.

  As shown in FIG. 10, the inclined portion 23 d protrudes obliquely downward from the second portion 23 a 2 of the top wall portion 23 a toward the middle portion in the front-rear direction of the lower rail 22. The inclined portion 23 d is inserted into the internal space 28 of the lower rail 22.

  The inclined portion 23d is provided with an inclined surface 23d1. The inclined surface 23d1 is inclined so as to approach the top wall portion 23a as it approaches the end portions 22p on both sides of the lower rail 22 in the front-rear direction. The inclined surface 23d1 is connected to the top surface 23a3 of the top wall portion 23a. In other words, the inclined surface 23d1 extends from the top surface 23a3 so as to approach the bottom wall portion 22a toward the middle portion in the front-rear direction. As a result, the fallen object that has fallen into the internal space 28 can be guided from the inclined surface 23 d 1 to the top surface 23 a 3 and thus to the outside of the lower rail 22.

  The protrusion 23e protrudes downward from the lower surface 23d2 of the inclined portion 23d in four locations in the front-rear direction and the width direction. A claw 23e1 is provided at the tip of the protrusion 23e, that is, the lower end. The protrusion 23e and the two attachment pieces 23c are arranged along the width direction when viewed from above.

  As shown in FIGS. 11 to 13, in the present embodiment, the end cap 23 is attached to the lower rail 22 from above. First, the protrusion 23e is aligned with the opening 22x in the front-rear direction and the width direction and inserted into the opening 22x. Then, the end cap 23 is pushed downward so that the lower surface 23d2 of the inclined portion 23d and the bottom wall portion 22a approach each other, and the claw 23f of the mounting piece 23c is engaged with the opening 22y. As a result, the end cap 23 is attached to the lower rail 22. Thus, in this embodiment, the projection 23e and the claw 23f of the mounting piece 23c form a two-stage mounting structure. Since the claw 23e1 of the protrusion 23e is configured in a tapered shape with the tip side tapered, insertion property to the opening 22x is easily improved.

  In the present embodiment, the claw 23f (attachment piece 23c) is guided while being expanded in the width direction by the contact between the guide surface 22v and the claw 23f during the period from the state of FIG. 12 to the state of FIG. Heading toward the opening 22y. Further, as the insertion proceeds, the guide wall portion 23g is inserted between the two inner wall portions 22t while being guided in the width direction by contact between the guide surface 22w and the guide wall portion 23g. With such a configuration, the end cap 23 can be attached to the lower rail 22 more easily, more smoothly, or more quickly from above.

  The end cap 23 can be configured, for example, such that the claw 23f of the attachment piece 23c is caught by the opening 22y in a state where the inclined portion 23d is elastically compressed and pressed against the bottom wall portion 22a. Thereby, it can suppress that the end cap 23 is attached to the lower rail 22 in the state which the inclination part 23d floats from the bottom wall part 22a, ie, the state where the clearance gap produced between the inclination part 23d and the bottom wall part 22a. The end cap 23 is not limited to this example. For example, an interposition member having elasticity (flexibility) for preventing a gap may be provided on the lower surface 23d2 of the inclined portion 23d.

  As described above, in the present embodiment, for example, the end cap 23 (cap) has the inclined surface 23d1 protruding from the top wall portion 23a to the internal space 28 of the lower rail 22 (rail). Therefore, according to the present embodiment, for example, when an object falls in the internal space 28, the falling object can be guided to the top surface 23a3 side of the end cap 23 by the inclined surface 23d1. Therefore, for example, a fallen object easily comes out of the lower rail 22.

  In the present embodiment, for example, the end cap 23 has a protrusion 23e that protrudes further downward from the protrusion 23b, and the opening 22x (first opening) into which the protrusion 23e is inserted in the bottom wall 22a. Part) is provided. Therefore, according to the present embodiment, for example, the end cap 23 can be positioned and attached to the lower rail 22 more easily, more smoothly, or more quickly by aligning the protrusion 23e and the opening 22x. it can. Further, when the falling object is taken out with the inclined surface 23d1 raised, the protruding part 23b is firmly supported by the bottom wall part 22a even when the protruding part 23b is pushed by the falling object. There is also an advantage that it becomes easy to take out.

  In the present embodiment, for example, the end caps 23 are located on both sides in the width direction (X direction) of the protruding portion 23b, protrude downward from the top wall portion 23a, and are provided with two claws 23f. Each of the two outer wall portions 22r is provided with an opening 22y (second opening) in which the claw 23f is engaged from the outside in the width direction of the outer wall portion 22r. Therefore, according to the present embodiment, for example, the lower rail 22 has a total of three locations, one location where the protrusion 23e is supported by the opening 22x and two locations where the claw 23f of the attachment piece 23c is supported by the opening 22y. The cap 23 can be supported more firmly. Therefore, the end cap 23 is more difficult to be detached from the state where the end cap 23 is attached to the lower rail 22.

  In the present embodiment, for example, the two attachment pieces 23c and the protrusions 23e are aligned along the width direction (X direction) when viewed from above. Therefore, according to the present embodiment, for example, compared to the case where the mounting piece 23c and the protrusion 23e are not aligned in the width direction when viewed from above, but are shifted in the front-rear direction (Y direction, first direction). Therefore, it is easy to improve the attachment of the end cap 23 to the lower rail 22 from above.

  Further, in the present embodiment, for example, the bottom wall portion 22a is provided with a concave portion 34 that is in contact with the concave protrusion portion 23b in the downward direction (the opposite direction to the Z direction, the vehicle lower side). Therefore, according to the present embodiment, for example, falling objects that have fallen into the inner space 28 of the lower rail 22 are likely to gather in the recess 34, and by using the inclined surface 23d1, the falling objects can be more easily moved to the outside of the lower rail 22. It may be possible to put out.

  In the present embodiment, for example, the lower rail 22 is positioned on the other end side in the front-rear direction (first direction) with respect to the two inner wall portions 22t (first inner wall portion), and is connected to the second connecting portion 22e (top portion). There are two inner wall portions 22z (second inner wall portions) that are connected to the inner end in the width direction and protrude downward from the vehicle, and the two inner wall portions 22z are located inward in the width direction from the two inner wall portions 22t. The projecting portion 23b has two guide wall portions 23g spaced apart from each other in the width direction and arranged in the front-rear direction with the two inner wall portions 22z. Therefore, according to the present embodiment, for example, the two guide wall portions 23g suppress the occurrence of a step in the width direction between the end cap 23 and the two inner wall portions 22z. Falling objects that have fallen in between can be put out of the lower rail 22 more smoothly.

  In the present embodiment, for example, a guide surface 22v (first guide surface) that is inclined so as to approach each other toward the top portion 22s toward the two outer wall portions 22r and guides the mounting piece 23c is provided. Therefore, according to the present embodiment, for example, the end cap 23 can be attached to the lower rail 22 more easily, more smoothly, or more quickly from the upper direction by the guide surface 22v.

  In the present embodiment, for example, the end cap 23 has a protruding portion 23b provided with a guide wall portion 23g that protrudes downward from the top wall portion 23a and is guided by the two inner wall portions 22t. Therefore, according to the present embodiment, for example, the end cap 23 is not easily displaced in the width direction of the lower rail 22 by the protruding portion 23b.

  In the present embodiment, for example, each of the two inner wall portions 22t has a guide surface 22w (second guide surface) facing in the width direction (X direction) and facing inward in the width direction as it goes downward. Have. Therefore, according to the present embodiment, for example, the end cap 23 can be attached to the lower rail 22 from the upper direction more easily by the guide surface 22w.
