Description

TECHNICAL FIELD The present invention relates to a sliding door structure including a sliding door provided movably between a closed position and an open position with respect to a vehicle body, and a wire harness routed between the vehicle body and the sliding door. .

Conventionally, as a wire harness routed between a vehicle body and a slide door, there has been known a wire harness whose outer circumference is protected by a bendable exterior member such as a corrugated tube having flexibility (for example, Patent Document 1 , 2).

JP 2010-017025 A JP 2013-162716 A

By the way, when the sliding door is in the closed position for closing the doorway to the vehicle body, the corrugated tube covering the wire harness may be exposed inside the vehicle body depending on the wiring route of the wire harness. In this case, there is a possibility that the appearance of the sliding door will be spoiled by the wire harness being visually recognized by the occupant of the vehicle. In addition, even if the function of the wire harness itself is not affected, the corrugated tube may be damaged by contact with the corrugated tube covering the wire harness by a passenger, a load, or the like. However, if the wire harness is routed outside the vehicle body of the interior plate (so-called trim) of the sliding door in order to prevent the exposure of the wire harness, the deformation of the wire harness accompanying the movement of the sliding door is restricted, and the sliding door and the wire harness are not inherently damaged. function may be impaired.

SUMMARY OF THE INVENTION The present invention has been made in view of the circumstances described above, and an object of the present invention is to provide a sliding door capable of preventing the wire harness from being exposed to the inside of the vehicle body without impairing the original functions of the sliding door and the wire harness. structure.

As shown in FIG. 1(a), when the sliding door 2 is placed in the closed position and the hatch 3 is closed, the sliding door 2 opens in the opening direction (that is, in the direction of the arrow X in FIG. 1(a)). When it is slid to , the hatch 3 opens as shown in FIG. 1(b). Thereafter, as shown in FIG. 1(c), when the slide door 2 is placed at the open position and the hatch 3 is opened, the entire hatch 3 is opened. That is, FIG. 1B shows the positional relationship between the sliding door 2 and the wire harness 11 when the sliding door 2 is in an intermediate position between the closed position and the open position (that is, the half-open state). . Conversely, as shown in FIG. 1(c), when the sliding door 2 is slid from the open position in the closing direction B (the direction of arrow Y in FIG. 1(c)), as shown in FIG. 1(b) , the hatch 3 closes. After that, as shown in FIG. 1(a), when the sliding door 2 reaches the closed position, the hatch 3 is closed.

Thus, the slide door 2 is configured to be movable back and forth between the open position and the closed position. The slide door 2 is provided with a cover 31 that can be opened and closed along with such movement. The cover 31 closes to cover the wire harness 11 inside the vehicle body when the slide door 2 is in the closed position, and prevents deformation of the wire harness 11 when the slide door 2 moves between the open position and the closed position. Do not open it. The construction and operation of cover 31 will be described in greater detail below.

A scuff plate 5 is provided at the hatch 3 of the vehicle body 1. - 特許庁The scuff plate 5 is provided in a recess 3a formed in the hatch 3 of the vehicle body 1 in this example. The wire harness 11 is arranged above the scuff plate 5 in this example. However, the wiring route of the wire harness 11 may be appropriately designed according to the shape of the vehicle body 1, and for example, the wire harness 11 may be arranged at a position away from the scuff plate 5 to the outside of the vehicle body.

The wire harness 11 is provided for power supply to various electrical components and auxiliary machines provided on the slide door 2 and for transmission and reception of various signals between the vehicle body 1 and the slide door 2 . The wire harness 11 has a plurality of wire bundles (not shown). The wire bundle is inserted through a protective tube (armoring member) 12 . As the protective tube 12, for example, a corrugated tube or Cableveyor (registered trademark) can be used.

The vehicle body 1 is provided with a vehicle body side power supply tool 14, and the slide door 2 is provided with a door side power supply tool 16. - 特許庁The protective tube 12 of the wire harness 11 has one end connected to the vehicle body side power supply tool 14 and the other end connected to the door side power supply tool 16 .

FIG. 2 is a horizontal sectional view of the vehicle-body-side power feeder 14 to which the vehicle-body-side end of the protective tube 12 of the wire harness 11 is connected. FIG. 3 is a horizontal cross-sectional view of the door-side power supply tool 16 to which the sliding door-side end of the protective tube 12 of the wire harness 11 is connected.

As shown in FIG. 2 , the vehicle-body-side power supply device 14 is supported by an outer member 21 fixed to the vehicle body 1 , and horizontally rotatable (swingable) by the outer member 21 . and an inner member 22 carrying twelve ends. With the outer member 21 and the inner member 22 , the vehicle-body-side power supply tool 14 supports the protection tube 12 so as to be horizontally rotatable (swingable) about the shaft 22 a of the inner member 22 . The outer member 21 has rotation restricting walls 21a and 21b. The rotation range of the inner member 22 is restricted by coming into contact with the rotation restriction walls 21a and 21b.

As shown in FIG. 3, the door-side power supply device 16 is supported by an outer member 25 fixed to the inner panel of the sliding door 2, and horizontally rotatable (swingable) by the outer member 25, and is provided with a wire harness. and an inner member 26 supporting the ends of the protective tubes 12 of 11. With the outer member 25 and the inner member 26 , the door-side power supply tool 16 supports the protective tube 12 so as to be horizontally rotatable (swingable) about the shaft 26 a of the inner member 26 . The outer member 25 has a rotation restricting wall 25a. The rotation range of the inner member 26 is restricted by coming into contact with the rotation restriction wall 25a. Further, in this example, the door-side power supply device 16 includes a spring member 27 that biases the inner member 26 in the opening direction of the sliding door 2 (that is, the direction of the arrow X in FIG. 1A) and toward the door. I have.

When the slide door 2 is opened and closed, the inner members 22 and 26 to which the ends of the protective tube 12 are connected rotate along with the movement of the protective tube 12 of the wire harness 11 . As a result, excessive bending at the ends of the wire harness 11 is suppressed when the slide door 2 is opened and closed.

<Structure and Operation of Cover in First Embodiment>
Next, the structure and operation of the cover 31 provided on the sliding door 2 will be described with reference to FIGS. 4 to 6. FIG.

As shown in FIGS. 4 to 6, an interior plate 6 (so-called trim) of the slide door 2 is provided inside the vehicle body of the door inner panel 8 (see FIGS. 5 and 6) of the slide door 2. As shown in FIGS. In the vicinity of the lower edge of the interior plate 6, a recessed portion 7 is provided so as to be recessed toward the outside of the vehicle body and extend in the longitudinal direction of the vehicle body. The cover 31 is arranged in the groove of the recess 7 so that when the sliding door 2 is in the closed position, the cover 31 is positioned further outside the vehicle body than the inner surface of the interior plate 6 .

As shown in FIGS. 5 and 6, the resin cover 31 includes a plate-like body 32 arranged to extend in the vehicle body front-rear direction in the recess 7 of the interior plate 6 extending in the vehicle body front-rear direction; and a hinge portion 33 that supports the plate-like body 32 to the upper inner wall of the recess 7 so as to be rotatable about the upper edge of the plate 32 . The plate-like body 32 has a curved shape that protrudes toward the wire harness 11 (that is, bulges outwardly of the vehicle) in a cross section along the width direction of the vehicle body. A tapered surface 31a and a tapered surface 31b are formed on the lower end surface (the end surface on the side opposite to the hinge portion 33) of the cover 31 (the plate-like body 32) at the rear end portion of the vehicle body and the front end portion of the vehicle body, respectively (Fig. 1(b) and FIG. 4).

As shown in FIGS. 4(a) and 5, when the sliding door 2 is in the closed position, the cover 31 (that is, the plate-like body 32) is positioned inside the vehicle body of the wire harness 11 and closed by its own weight. (see also FIG. 1(a)). As a result, the wire harness 11 is prevented from being exposed by covering the inside of the vehicle body of the wire harness 11 with the cover 31 .

Furthermore, in the closed state of the cover 31, the cover 31 is provided on the outer side of the vehicle body with respect to the inner surface of the interior plate 6, as described above. As a result, the cover 31 itself is less likely to be visually recognized by the occupant, and the cover 31 is less likely to be contacted by a load.

When the slide door 2 moves toward the open position from the state shown in FIGS. 4A and 5, the wire harness 11 moves toward the slide door 2 as the slide door 2 moves, as shown in FIG. 4B. Deforms in the direction away from (inside the car body). Due to this deformation, the wire harness 11 pushes the cover 31 toward the inside of the vehicle body (see also FIG. 1(b)). By this pressing force, as shown in FIG. 6, the cover 31 is rotated inwardly and upwardly of the vehicle body so as to allow the deformation of the wire harness 11 to be opened. At this time, in the middle of the rotation of the cover 31 in the opening direction, the wire harness 11 moves while sliding on the tapered surface 31a of the cover 31, so that the cover is more open than when the tapered surface 31a is not provided. 31 can be smoothly rotated in the opening direction.

When the slide door 2 reaches the open position, the wire harness 11 is deformed toward the slide door 2 (outside the vehicle body) as shown in FIG. Since the cover 31 has moved to the inside of the recess 7 of the plate 6, the above-described pressing force disappears, and the cover 31 is turned outward and downward by its own weight to be in a closed state. During the turning of the cover 31 in the closing direction, the wire harness 11 moves while sliding on the tapered surface 31b of the cover 31, so that the closing of the cover 31 is faster than when the tapered surface 31b is not provided. Rotational motion in the direction can be performed smoothly. Since the wire harness 11 is curved as shown in FIG. 1(b), the cross-section of the wire harness 11 is shown at two locations in the cross-sectional view shown in FIG.

Conversely, when the slide door 2 moves from the open position (that is, the cover 31 is closed) to the closed position, the wire harness 11 first moves away from the slide door 2 (inside the vehicle body) as the slide door 2 moves. ) and the cover 31 is opened. After that, as the sliding door 2 moves, the wire harness 11 deforms toward the sliding door 2 (outside the vehicle body), and the wire harness 11 moves into the recess 7 of the interior plate 6 of the sliding door 2. , the cover 31 is rotated by its own weight to return to the closed state.

Thus, the cover 31 is closed so as to cover the inside of the vehicle body of the wire harness 11 when the slide door 2 is in the closed position, and the wire is closed when the slide door 2 moves between the closed position and the open position. Open to allow deformation of the harness 11 . In this example, the cover 31 has a cross-sectional shape that protrudes toward the wire harness 11 (in other words, bulges toward the outside of the vehicle). Therefore, compared with the case where the cover 31 has a cross-sectional shape that protrudes in the direction away from the wire harness 11 (in other words, the cover 31 bulges toward the inside of the vehicle) or the case where the cover 31 has a flat shape, the cover 31 and the wire harness 11 slides smoothly. Therefore, opening and closing of the cover 31 becomes easier.

As described above, according to the sliding door structure according to the first embodiment of the present invention, when the sliding door 2 is in the closed position, the inside of the vehicle interior of the wire harness 11 is covered with the cover 31 . Therefore, exposure of the wire harness 11 is prevented. On the other hand, when the sliding door 2 moves between the closed position and the open position, the cover 31 opens so as not to prevent the wire harness 11 from being deformed. Therefore, the degree of freedom of deformation of the wire harness 11 is not impaired. Therefore, according to the sliding door structure of this configuration, it is possible to prevent the wiring harness 11 from being exposed to the inside of the vehicle body without impairing the original functions of the sliding door 2 and the wiring harness 11 .

Furthermore, according to the sliding door structure according to the first embodiment, when the sliding door 2 moves from the closed position to the open position, the wire harness 11 that deforms away from the sliding door 2 pushes the cover 31 toward the inside of the vehicle body. When the cover 31 shifts from the closed state to the open state and the slide door 2 moves from the open position to the closed position, the wire harness 11 deforms so as to approach the slide door 2, thereby opening the cover 31. The desired operation of the cover 31 can be realized by shifting from the closed state to the closed state by its own weight.

Furthermore, according to the sliding door structure according to the first embodiment, the cover 31 has a cross-sectional shape that protrudes toward the wire harness 11 . Therefore, it becomes easier to open and close the cover 31 when the wire harness 11 is deformed.

Furthermore, according to the sliding door structure according to the first embodiment, the cover 31 is arranged outside the vehicle body with respect to the inside surface of the interior plate 6 of the sliding door 2 . As a result, when the slide door 2 is in the closed position, the cover 31 itself is less likely to be visually recognized by the occupant, and the load or the like is less likely to come into contact with the cover 31 . Therefore, it is possible to more properly prevent the wire harness 11 from being exposed to the inside of the vehicle body.

<Overall Configuration of Second Embodiment>
Next, a sliding door structure according to a second embodiment of the present invention will be described with reference to FIGS. 7 to 9. FIG. The second embodiment further includes a spring 41 (see FIGS. 8 and 9) and a driving member 42 (see FIGS. 7 to 9), and the cover 31 projects away from the wire harness 11. , and that the cover 31 is not provided with the tapered surfaces 31a and 31b. The spring 41 and the driving member 42 will be described below.

The spring 41 is provided so as to be engaged with both the cover 31 and the interior plate 6, and has a function of always biasing the cover 31 in the rotational direction from the closed state to the open state. Any configuration may be adopted as the configuration of the spring 41 as long as it has a function of always biasing the cover 31 in the rotational direction from the closed state to the open state.

The driving member 42 is a member that is pressed to the outside of the vehicle body by the wire harness 11 in order to drive the cover 31 from the open state to the closed state. As shown in FIGS. 7 to 9 (particularly, FIGS. 8 and 9), the driving member 42 has a plate-like shape extending in the longitudinal direction of the vehicle body, and rotates relative to the plate-like body 32 in a predetermined manner. It is provided integrally with the cover 31 so as to rotate integrally with the plate-like body 32 at a position moved (rotated) to the outside of the vehicle body by an angle.

As shown in FIG. 7(a), the driving member 42 is in contact with a predetermined position on the rear side of the vehicle body relative to the central position in the extending direction of the wire harness 11 when the sliding door 2 is in the closed position in the vehicle body longitudinal direction. provided only where possible. In this example, the driving member 42 is provided only in a region near the rear end of the vehicle body in the plate-like body 32 extending in the vehicle front-rear direction.

As shown in FIG. 8, when the slide door 2 is in the closed position, the wire harness 11 opposes the biasing force of the spring 41 and presses the driving member 42 toward the outside of the vehicle body, thereby 32) is positioned inside the vehicle body of the wire harness 11 and is maintained in a closed state (see also FIG. 7(a)). As a result, the wire harness 11 is prevented from being exposed by covering the inside of the vehicle body of the wire harness 11 with the cover 31 .

Furthermore, in the closed state of the cover 31, the cover 31 is provided on the outer side of the vehicle body with respect to the inner surface of the interior plate 6, as described above. As a result, the cover 31 itself is less likely to be visually recognized by the occupant, and the cover 31 is less likely to be contacted by a load.

When the slide door 2 moves toward the open position from the state shown in FIG. Due to this deformation, the wire harness 11 is released from pressing the driving member 42 . As a result, as shown in FIG. 9, the cover 31 is rotated inwardly and upwardly of the vehicle body by the biasing force of the spring 41 to be in an open state. The open state of the cover 31 is maintained even when the slide door 2 is in the open position, as shown in FIG. 7(c). Since the wire harness 11 is curved as shown in FIG. 7B, the cross-section of the wire harness 11 is shown at two locations in the cross-sectional view shown in FIG.

Conversely, when the slide door 2 moves from the open position (that is, the cover 31 is open) to the closed position, the wire harness 11 moves toward the slide door 2 (outside the vehicle body) as the slide door 2 moves. transform. Due to this deformation, the wire harness 11 itself moves into the recess 7 of the interior plate 6 of the sliding door 2 . As the wire harness 11 moves into the recess 7, the wire harness 11 pushes the driving member 42 outward while resisting the biasing force of the spring 41, thereby rotating the cover 31 outward and downward. to return to the closed state. When the sliding door 2 returns to the closed position, the cover 31 also returns to the closed state.

Thus, the cover 31 is closed so as to cover the inside of the vehicle body of the wire harness 11 when the slide door 2 is in the closed position, and the wire is closed when the slide door 2 moves between the closed position and the open position. Open to allow deformation of the harness 11 .

As described above, according to the sliding door structure according to the second embodiment of the present invention, when the sliding door 2 moves from the open position to the closed position, the wire harness 11 that deforms so as to approach the sliding door 2 moves the driving member 42 to the vehicle body. By pushing outward, the cover 31 shifts from the open state to the closed state, and when the slide door 2 moves from the closed position to the open position, the wire harness 11 is deformed away from the slide door 2, thereby closing the cover. Desired operation of the cover 31 can be realized by the movement of the cover 31 from the closed state to the open state by the biasing force of the spring 41 .

Furthermore, according to the slide door structure of the second embodiment, the driving member 42 is configured to rotate integrally with the plate-like body 32 , so the driving member 42 is provided separately from the plate-like body 32 . The sliding door structure can be simplified more than when it is used.

Furthermore, according to the sliding door structure according to the second embodiment, the driving member 42 is positioned at a predetermined position rearward of the vehicle body from the central position in the extending direction of the wire harness 11 when the sliding door 2 is in the closed position in the vehicle body front-rear direction. It is provided only in the area where the point can contact. Here, when the slide door 2 moves from the closed position toward the open position, the rear portion of the slide door 2 moves toward the outside of the vehicle body 1 before the front portion of the slide door 2. Moving. Therefore, the portion of the wire harness 11 on the rear side of the vehicle body relative to the center position in the extending direction deforms so as to move away from the slide door 2 before the portion of the wire harness 11 on the front side of the vehicle body relative to the center position in the extending direction. Therefore, according to this configuration, the cover 31 can be shifted from the closed state to the open state at an early stage after the slide door 2 starts moving from the closed position toward the open position.

Furthermore, according to the sliding door structure according to the second embodiment, the cover 31 is arranged outside the vehicle body with respect to the inside surface of the interior plate 6 of the sliding door 2 . As a result, when the slide door 2 is in the closed position, the cover 31 itself is less likely to be visually recognized by the occupant, and the load or the like is less likely to come into contact with the cover 31 . Therefore, it is possible to more properly prevent the wire harness 11 from being exposed to the inside of the vehicle body.

<Third Embodiment>
Next, a slide door structure according to a third embodiment of the present invention will be described with reference to FIGS. 10 and 11. FIG. In addition, the same components as those in the first and second embodiments are denoted by the same reference numerals, and descriptions thereof are omitted.

As shown in FIGS. 10 and 11 , in the third embodiment, the cover 31 is provided on the door-side power supply tool (power supply tool) 16 attached to the slide door 2 . The door-side power supply tool 16 is supported by an outer member 25 fixed to the inner panel of the slide door 2 , and horizontally rotatable (swingable) by the outer member 25 . and an inner member 26 that supports the portion. In the cover 31 , a plate-like body 32 arranged to extend in the longitudinal direction of the vehicle body is formed integrally with the outer member 25 via a hinge portion 33 . The cover 31 is supported on the outer member 25 by a hinge portion 33 above a supporting portion of the wire harness 11 where the outer member 25 and the inner member 26 are rotatably connected. The cover 31 has a tapered surface 31a and a tapered surface 31b at the vehicle body rear side end portion and the vehicle body front side end portion of the plate-like body 32, respectively. The cover 31 has an edge portion having tapered surfaces 31a and 31b that is slightly inclined toward the interior of the vehicle.

As shown in FIG. 10, when the slide door 2 is in the closed position, the cover 31 (that is, the plate-like body 32) is positioned inside the vehicle interior at the supporting portion of the wire harness 11 in the door-side power supply tool 16, and its own weight is applied. is kept closed by As a result, the supporting portion of the wire harness 11 in the door-side power supply tool 16 is covered with the cover 31 to prevent the supporting portion of the wire harness 11 from being exposed.

When the slide door 2 moves toward the open position from the state shown in FIG. 10, the wire harness 11 is deformed away from the slide door 2 (inside the vehicle body) as the slide door 2 moves, as shown in FIG. do. Due to this deformation, the wire harness 11 pushes the cover 31 toward the inside of the vehicle body (see also FIG. 1(b)). Due to this pressing force, the cover 31 is rotated inwardly and upwardly of the vehicle body so as to allow the wire harness 11 to be deformed and the wire harness 11 to be rotated at the supporting portion, thereby opening the cover 31 . At this time, in the middle of the rotation of the cover 31 in the opening direction, the wire harness 11 moves while sliding on the tapered surface 31b of the cover 31, so that the cover 31 is more open than when the tapered surface 31b is not provided. can be smoothly rotated in the opening direction.

When the slide door 2 reaches the open position, as shown in FIG. As a result, the above-described pressing force disappears, and the cover 31 rotates outwardly and downwardly of the vehicle body by its own weight to be closed. At a stage during the rotation of the cover 31 in the closing direction, the wire harness 11 moves while sliding on the tapered surface 31a of the cover 31, so that the closing direction of the cover 31 is greater than when the tapered surface 31a is not provided. Rotational motion to can be made smoothly.

Conversely, when the slide door 2 moves from the open position (that is, the cover 31 is closed) to the closed position, the wire harness 11 first moves away from the slide door 2 (inside the vehicle body) as the slide door 2 moves. ) and the cover 31 is opened. After that, as the slide door 2 moves, the wire harness 11 deforms toward the slide door 2 (outside the vehicle body), and the wire harness 11 runs along the slide door 2, so that the cover 31 is rotated by its own weight. to return to the closed state.
