Description

The present invention relates to a protector and a wire harness.

As an example of a conventional technology relating to a wire harness protector, Patent Document 1 discloses a protector that includes a base portion that is fixed to the sliding door of a vehicle, and a rotating portion that is supported rotatably around a rotation center that extends in the vertical direction of the vehicle relative to the base portion, and through which a wiring material that is routed from the vehicle body to the sliding door is inserted.

JP 2020-102950 A

In this type of protector, for example, the base portion may be provided with a bearing portion having a long hole that supports the rotating portion so that it can rotate around a rotation center that extends along the vertical direction of the vehicle, and supports the rotating portion so that it can slide along an extension direction that intersects the vertical direction. In this case, for example, the long hole of the bearing portion may be exposed and not covered by the rotating portion, and there is a risk that foreign matter or the like may enter the long hole of the bearing portion.

The present invention was made in consideration of the above circumstances, and aims to provide a protector and wire harness that can prevent the intrusion of foreign objects.

In order to achieve the above object, the protector according to the present invention comprises a base portion fixed to a sliding door of a vehicle, and a rotating portion supported rotatably about a rotation center extending along the vertical direction of the vehicle relative to the base portion and through which a wiring material is inserted that is routed from the body of the vehicle to the sliding door, the rotating portion comprising a tubular portion extending along an extension direction intersecting the vertical direction and having one end open in the extension direction through which the wiring material is inserted, an end wall portion closing the other end of the tubular portion in the extension direction and being formed in an arc shape when viewed from the vertical direction, The base portion has a shaft portion that protrudes downward from the cylindrical portion along the vertical direction, and the base portion supports the shaft portion rotatably around the rotation center, and has a first bearing portion with a long hole that supports the shaft portion slidably along the extension direction between a first position corresponding to a fully closed state of the sliding door and a second position corresponding to a fully open state of the sliding door, and the end wall portion is eccentrically disposed so that when the shaft portion is positioned at the first position, the center of the arc of the end wall portion that is formed in an arc shape is positioned on the second position side with respect to the rotation center of the shaft portion.

In the protector and wire harness according to the present invention, the end wall portion is eccentrically disposed so that the center of the arc of the end wall portion formed in an arc shape is located on the second position side relative to the center of rotation of the shaft portion when the shaft portion is located in the first position. With this configuration, the protector and wire harness can, for example, cover the long hole of the first bearing portion with the end wall portion disposed eccentrically with respect to the center of rotation of the shaft portion and the lower wall of the cylindrical portion connected to the end wall portion, thereby preventing the long hole of the first bearing portion from being exposed to the rotating portion when the shaft portion is located in the first position. As a result, the protector and wire harness have the effect of preventing foreign matter from entering the long hole of the first bearing portion.

[Embodiment]
FIG. 1 is a front view of a wire harness WH to which a protector 1 according to an embodiment is applied, and FIG. 2 is a side view of the wire harness WH. The protector 1 of the present embodiment shown in FIGS. 1 and 2 is incorporated into the wire harness WH to be routed in a vehicle 100. Here, the wire harness WH is, for example, a bundle of wiring materials W used for power supply and signal communication to connect each device mounted on the vehicle 100, and the wiring materials W are connected to each device by connectors or the like. The wire harness WH of the present embodiment includes a wiring material W having conductivity and a protector 1 that protects the wiring material W. In addition, the wire harness WH may be configured to include various components such as a corrugated tube, a grommet, an electrical connection box, a fixture, and a connector.

In the following description, the first direction, the second direction, and the third direction intersect with each other, and the first direction is referred to as the "extension direction X", the second direction is referred to as the "depth direction Y", and the third direction is referred to as the "up-down direction Z". Here, the extension direction X, the depth direction Y, and the up-down direction Z are approximately perpendicular to each other. The extension direction X typically corresponds to the extension direction of the protector 1, the extension direction of the rotating part 3 (tube part 30) when the rotating part 3 of the protector 1 described later is positioned at the first position P1 (see FIG. 3) relative to the base part 2, the front-rear direction of the vehicle, etc. The depth direction Y typically corresponds to the depth direction (thickness direction) of the protector 1, the depth direction of the rotating part 3 (tube part 30) when the rotating part 3 of the protector 1 is positioned at the first position P1 (see FIG. 3) relative to the base part 2, the vehicle width direction, etc. The up-down direction Z typically corresponds to the up-down direction (height direction) of the protector 1, the up-down direction of the vehicle, etc. In addition, unless otherwise specified, the directions used in the following explanation refer to the direction when the protector 1 is installed in the vehicle.

As shown in Figures 1 and 2, the protector 1 of this embodiment is a protector for a sliding door that is arranged on a sliding door 110 of a vehicle 100. The vehicle 100 has a pair of sliding doors 110A, 110B (see Figure 2) arranged on both sides in the depth direction Y (vehicle width direction). The sliding door 110 slides along an extension direction X (vehicle front-rear direction) relative to a body 120 of the vehicle 100. The vehicle 100 has a driving mechanism such as a motor that moves the sliding door 110 along the extension direction X. A wiring material W that is arranged from the body 120 to the sliding door 110 is inserted into the protector 1.

The wiring material W is, for example, composed of a wire bundle in which a plurality of electric wires are bundled together, and a tubular exterior material that covers the wire bundle. The exterior material is, for example, a corrugated tube. The wiring material W has relatively high flexibility and good bendability in an installed state in which the exterior material is attached to the electric wire bundle. When the wiring material W of this embodiment is in an installed state in which the exterior material is attached to the electric wire bundle, and is bent by applying an external force from a natural state (approximately straight state) in which no external force is applied, the bent portion elastically deforms, and an elastic reaction force is generated in the bent portion, so that the original state is attempted to be restored.

As shown in FIG. 1, one end of the wiring material W is connected to the device 130 of the sliding door 110. The device 130 includes a switch for opening and closing the sliding door 110. The other end of the wiring material W is connected to a power source, a control device, etc. arranged in the body 120 (see FIG. 2). The body 120 is provided with a holding member 140 that holds the wiring material W. The wiring material W extends from the holding member 140 to the protector 1 of the sliding door 110 along the depth direction Y (vehicle width direction). The holding member 140 and the protector 1 hold a portion of the wiring material W so that the wiring material W follows the movement of the sliding door 110.

The protector 1 includes, for example, a base portion 2 fixed to the sliding door 110, and a rotating portion 3 supported by the base portion 2 so as to be rotatable around a rotation center extending along the vertical direction Z. The wiring material W is inserted through the rotating portion 3 and the base portion 2. As shown in FIG. 2, the base portion 2 is fixed to a panel 111 of the sliding door 110. The panel 111 is, for example, an inner panel. The sliding door 110 has an interior material 112 that covers the panel 111. The rotating portion 3 is, for example, not covered by the interior material 112 and can rotate without interfering with the interior material 112. The base portion 2 is, for example, exposed toward the interior space of the vehicle 100.

Figure 3 is a perspective view of the wire harness WH to which the protector 1 is applied, and Figure 4 is an exploded perspective view of the protector 1, showing the rotating part 3 positioned in a first position P1 relative to the base part 2, which corresponds to the fully closed state of the sliding door 110. As shown in Figures 3 and 4, the base part 2 is configured to include, for example, a first bearing part 24, a second bearing part 23, a passage part 25, an attachment part 26, and a connection part 27. The first bearing part 24 and the second bearing part 23 are parts that support the rotating part 3 to be rotatable around a rotation center Ax1 extending along the vertical direction Z. The first bearing part 24 and the second bearing part 23 are provided on the base part 2 with a gap between them in the vertical direction Z.

Before describing the first bearing portion 24, the second bearing portion 23 will be described first. The second bearing portion 23 is provided above the rotating portion 3 in the vertical direction Z. The second bearing portion 23 is provided with an elongated hole 23a that supports a cylindrical portion 35 (see FIG. 4) of the rotating portion 3 described later so that the cylindrical portion 35 can rotate around the rotation center Ax1 and can slide along the extension direction X. Specifically, the elongated hole 23a includes a first groove portion 23a1 and a second groove portion 23a2 that communicates with the first groove portion 23a1 and is positioned offset in the extension direction X with respect to the first groove portion 23a1.

The first groove 23a1 is a portion that engages with the cylindrical portion 35 when the rotating portion 3 is positioned at the first position P1 corresponding to the fully closed state of the sliding door 110. The first groove 23a1 is formed in an arc shape (semicircle shape) along the outer circumferential surface of the cylindrical portion 35. The second groove 23a2 is a portion that engages with the cylindrical portion 35 when the rotating portion 3 is positioned at the second position P2 (see FIG. 6) corresponding to the fully open state of the sliding door 110. The second groove 23a2 is formed in an arc shape (semicircle shape) along the outer circumferential surface of the cylindrical portion 35. The long hole 23a is configured as a horizontally elongated approximately elliptical shape along the extension direction X as a whole by the above-mentioned first groove 23a1 and second groove 23a2.

The base portion 2 is formed by combining multiple parts including, for example, the case 21 and the cover 22 (see FIG. 3), and the second bearing portion 23 is formed by combining semi-cylindrical portions provided on the case 21 and the cover 22, respectively. The case 21 and the cover 22 are formed, for example, from a resin material or the like. The cover 22 is assembled to the case 21 in a stacked state on one side in the depth direction Y. The case 21 and the cover 22 are formed separately from each other and are integrated with each other, for example, by a snap fit using claw engagement.

The first bearing portion 24 is provided below the rotating portion 3 in the vertical direction Z. The first bearing portion 24 is provided with an elongated hole 24a that supports a shaft portion 34 (see FIG. 5) of the rotating portion 3 described later so that the shaft portion 34 can rotate about a rotation center Ax1 and can slide along the extension direction X. Like the elongated hole 23a described above, the elongated hole 24a includes a first groove portion 24a1 and a second groove portion 24a2 that communicates with the first groove portion 24a1 and is positioned offset in the extension direction X from the first groove portion 24a1.

The first groove 24a1 is a portion that engages with the shaft 34 when the rotating part 3 is positioned at the first position P1 corresponding to the fully closed state of the sliding door 110. The first groove 24a1 is formed in an arc shape (semicircle shape) along the outer circumferential surface of the shaft 34. The second groove 24a2 is a portion that engages with the shaft 34 when the rotating part 3 is positioned at the second position P2 corresponding to the fully open state of the sliding door 110. The second groove 24a2 is formed in an arc shape (semicircle shape) along the outer circumferential surface of the shaft 34. The long hole 24a is configured as a horizontally elongated approximately ellipse along the extension direction X by the above-mentioned first groove 24a1 and second groove 24a2 as a whole. In addition, the long hole 24a is positioned so as to overlap the long hole 23a of the second bearing part 23 in the vertical direction Z.

As shown in FIG. 3, the passage 25 is a portion through which the wiring material W is inserted. The passage 25 is provided above the second bearing 23 in the vertical direction Z, and extends along the vertical direction Z. The passage 25 is formed, for example, by combining a gutter 21a provided in the case 21 and a flat plate 22a provided in the cover 22. The internal space of the passage 25 is connected to the internal spaces 36, 37 of the rotating part 3. This allows the wiring material W to be inserted between the rotating part 3 and the base part 2.

The mounting portion 26 is a portion for fixing the base portion 2 to the sliding door 110. The mounting portion 26 is provided on both sides of the second bearing portion 23 in the extension direction X, and extends along the extension direction X. The mounting portion 26 is formed, for example, by combining an overhang portion provided on the case 21 and an overhang portion provided on the cover 22. The mounting portion 26 is provided with through holes 2a and 2b through which fastening members such as bolts that fasten the base portion 2 and the sliding door 110 pass in the depth direction Y.

The connection portion 27 is a portion for connecting the first bearing portion 24 and the second bearing portion 23. The connection portion 27 includes, for example, a bottom wall 27a and a standing wall 27b. The connection portion 27 is formed by the bottom wall 27a and the standing wall 27b in a generally L-shape that is open toward the rotating portion 3 as a whole. The bottom wall 27a is formed, for example, in a flat plate shape and extends along the depth direction Y. The cylindrical first bearing portion 24 having the above-mentioned long hole 24a formed therein is provided so as to protrude upward from the bottom wall 27a. The standing wall 27b is formed, for example, in a flat plate shape and extends along the up-down direction Z. The standing wall 27b connects the other end of the bottom wall 27a in the depth direction Y to the other end of the second bearing portion 23 in the depth direction Y.

Figure 5 is a cross-sectional view of the rotating part 3 in the protector 1 of Figure 4. As shown in Figures 4 and 5, the rotating part 3 is composed of, for example, a tube part 30, an end wall part 33, an axis part 34, and a cylindrical part 35. The tube part 30 is a part into which the wiring material W is inserted and which rotates (pivots, swings) around a rotation center Ax1 extending along the vertical direction Z relative to the base part 2. The tube part 30 extends along an extension direction X in Figures 4 and 5, which is a direction intersecting the vertical direction Z, and rotates in response to the opening and closing of the sliding door 110 described above.

The cylindrical portion 30 is formed by combining multiple parts including, for example, a semi-cylindrical first part 31 and a semi-cylindrical second part 32. The first part 31 and the second part 32 are formed, for example, from a resin material or the like. The first part 31 is assembled to the second part 32 in a stacked state on the upper side in the vertical direction Z. The first part 31 and the second part 32 are formed separately from each other and are integrated with each other, for example, by snap-fitting through claw engagement. The cylindrical portion 30 is formed into a generally rectangular cylindrical shape as a whole by assembling the first part 31 and the second part 32 together.

The second part 32 has, for example, a bottom wall 32a and a pair of side walls 32b intersecting with the bottom wall 32a, and has a cross section intersecting with the extension direction X formed into a substantially U-shape. The bottom wall 32a and the pair of side walls 32b are structures for partitioning the internal space 36 of the tube portion 30. The internal space 36 is a space through which the wiring material W is inserted and routed. The bottom wall 32a is formed, for example, in a flat plate shape and extends along the extension direction X. The pair of side walls 32b are formed to protrude upward in the vertical direction Z from both ends of the bottom wall 32a in the depth direction Y, and extend along the extension direction X.

The first part 31 is assembled to the second part 32 and covers (closes) the internal space 36 of the second part 32 from above in the vertical direction Z. The first part 31 has, for example, an upper wall 31a and a pair of side walls 31b intersecting with the upper wall 31a, and the cross section intersecting with the extension direction X is formed into a substantially U-shape. The upper wall 31a and the pair of side walls 31b are structures for partitioning the internal space 36 of the tube part 30. The upper wall 31a is formed, for example, in a flat plate shape along the lower wall 32a, and is provided at a distance from the lower wall 32a in the vertical direction Z. The pair of side walls 31b are formed to protrude downward in the vertical direction Z from both ends of the upper wall 31a in the depth direction Y, and are overlapped inside the pair of side walls 32b.

The end wall portion 33 is a portion for closing the other end (opposite the open end of the internal space 36) in the extension direction X of the tube portion 30 formed by the first part 31 and the second part 32. As shown in FIG. 4, the end wall portion 33 is formed in an arc shape when viewed from the vertical direction Z, for example, and extends along the vertical direction Z. The end wall portion 33 connects the other end of the upper wall 31a in the extension direction X to the other end of the lower wall 32a in the extension direction X. As a result, the tube portion 30 has an internal space 36 that is surrounded by the upper wall 31a, the lower wall 32a, the pair of side walls 31b, 32b, and the end wall portion 33 and is open to one side in the extension direction X.

The end wall portion 33 is configured to include, for example, a first end wall portion 31d provided on the first part 31 and a second end wall portion 32c provided on the second part 32. The first end wall portion 31d and the second end wall portion 32c are each curved in an arc shape (semicircular shape) while being convex toward the other side of the extension direction X (the side opposite to the open end of the internal space 36). The outer surface of the first end wall portion 31d is provided with a recess 31e (see FIG. 5) into which the second end wall portion 32c engages, and the first end wall portion 31d and the second end wall portion 32c are assembled in a state of being aligned in the vertical direction Z. As a result, the outer surface of the first end wall portion 31d and the outer surface of the second end wall portion 32c are aligned in a straight line in the vertical direction Z without providing a step or the like in the extension direction X between the first end wall portion 31d and the second end wall portion 32c.

The cylindrical portion 35 is supported by the second bearing portion 23 of the base portion 2 so as to be rotatable around the center of rotation Ax1, and is supported so as to be slidable along the extension direction X. The cylindrical portion 35 protrudes upward in the vertical direction Z from the upper wall 31a of the first part 31. The cross-sectional shape of the cylindrical portion 35 is circular. The cylindrical portion 35 is provided at the other end of the tube portion 30 in the extension direction X. The internal space 37 of the cylindrical portion 35 is connected to the internal space 36 of the tube portion 30. As a result, the wiring material W is inserted between the tube portion 30 and the cylindrical portion 35.

The shaft portion 34 is supported by the first bearing portion 24 of the base portion 2 so as to be rotatable around the center of rotation Ax1, and is supported so as to be slidable along the extension direction X. The shaft portion 34 protrudes downward in the up-down direction Z from the lower wall 32a of the second part 32. The cross-sectional shape of the shaft portion 34 is circular. The shaft portion 34 is provided at the other end of the tube portion 30 in the extension direction X. The shaft portion 34 is configured coaxially with the cylindrical portion 35, and the center of rotation Ax1 of the shaft portion 34 and the center of rotation Ax1 of the cylindrical portion 35 coincide with each other. When the shaft 34 is positioned at the first position P1, which corresponds to the fully closed state of the sliding door 110, it is positioned at one end of the elongated hole 24a in the extension direction X (first groove 24a1), and when the shaft 34 is positioned at the second position P2, which corresponds to the fully open state of the sliding door 110, it is positioned at the other end of the elongated hole 24a in the extension direction X (second groove 24a2).

Here, in this embodiment, the end wall portion 33 is eccentrically disposed so that, when the shaft portion 34 is positioned at the first position P1 described above, the arc center Ax2 of the end wall portion 33 formed in an arc shape is positioned on the second position P2 side with respect to the rotation center Ax1 of the shaft portion 34. That is, when the shaft portion 34 is positioned at the first position P1, in other words, when the shaft portion 34 (rotating portion 3) is moved toward one side in the extension direction X, the end wall portion 33 protrudes to the other side (second position P2 side) in the extension direction X so as to block the long hole 24a of the first bearing portion 24. This prevents the long hole 24a of the first bearing portion 24 from being exposed without being covered by the rotating portion 3, at least when the shaft portion 34 is positioned at the first position P1.

Figure 6 is an exploded perspective view of the protector 1, in which the rotating part 3 is positioned at the second position P2 relative to the base part 2, which corresponds to the fully open state of the sliding door 110, and Figure 7 is an exemplary explanatory diagram illustrating the operation of the protector 1 in opening and closing the sliding door 110. As shown in Figures 6 and 7, in this embodiment, the rotating part 3 is supported rotatably around a rotation center Ax1 extending along the vertical direction Z relative to the base part 2, and is supported slidably along the extension direction X between a first position P1 corresponding to the fully closed state of the sliding door 110 and a second position P2 corresponding to the fully open state of the sliding door 110.

Specifically, in this embodiment, for example, when the sliding door 110 transitions from a fully closed state to a fully open state, the rotating part 3 first slides from the first position P1 to the second position P2 along the extension direction X. This makes it easier to bend the wiring material W that is wired between the body 120 of the vehicle 100 and the sliding door 110 in a convex state toward one side of the depth direction Y (the inner side in the vehicle width direction) by providing an angle to the wiring material W. Then, while positioned at the second position P2, the rotating part 3 rotates around the rotation center Ax1 that extends along the vertical direction Z, and moves the wiring material W to a position corresponding to the fully open state of the sliding door 110. Note that, when the sliding door 110 transitions from a fully open state to a fully closed state, the wiring material W can be moved to a position corresponding to the fully closed state of the sliding door 110 by performing the reverse operation to the above-mentioned operation.

When the sliding door 110 is in a fully closed state, the protector 1 is exposed to the interior space of the vehicle 100. For this reason, the end wall portion 33 of the rotating portion 3 described above is configured to close the long hole 24a of the first bearing portion 24 at least when the shaft portion 34 is positioned at the first position P1. In addition, in this embodiment, the end wall portion 33 is configured to have an arc shape when viewed from the vertical direction Z. This prevents the end wall portion 33 from interfering with the vertical wall 27b of the connection portion 27 as the rotating portion 3 rotates around the rotation center Ax1 relative to the base portion 2.

As described above, in the protector 1 and wire harness WH of this embodiment, the end wall portion 33 is eccentrically disposed so that the arc center Ax2 of the end wall portion 33 formed in an arc shape is located on the second position P2 side with respect to the rotation center Ax1 of the shaft portion 34 when the shaft portion 34 is located at the first position P1. With this configuration, the protector 1 and wire harness WH can cover the long hole 24a of the first bearing portion 24 with, for example, the end wall portion 33 eccentrically disposed with respect to the rotation center Ax1 of the shaft portion 34 and the lower wall 32a of the tube portion 30 connected to the end wall portion 33, and thus can prevent the long hole 24a of the first bearing portion 24 from being exposed to the rotating portion 3 when the shaft portion 34 is located at the first position P1. As a result, the protector 1 and wire harness WH can prevent foreign matter from entering the long hole 24a of the first bearing portion 24.

In addition, in the protector 1 and wire harness WH of this embodiment, when the shaft portion 34 is positioned at the first position P1, the end wall portion 33 closes the long hole 24a of the first bearing portion 24. With this configuration, the protector 1 and wire harness WH can close the long hole 24a of the first bearing portion 24, for example, with the end wall portion 33 and the lower wall 32a of the cylindrical portion 30, so that the long hole 24a of the first bearing portion 24 can be more reliably prevented from being exposed to the rotating portion 3 when the shaft portion 34 is positioned at the first position P1. As a result, the protector 1 and wire harness WH can more reliably prevent foreign matter from entering the long hole 24a of the first bearing portion 24.

In the protector 1 and wire harness WH of this embodiment, the tubular portion 30 has a semi-cylindrical first part 31 and a semi-cylindrical second part 32 that fit together in the vertical direction Z. The first part 31 is provided with a first end wall part 31d that constitutes part of the end wall part 33, and the second part 32 is provided with a second end wall part 32c that constitutes part of the end wall part 33 and is positioned alongside the first end wall part 31d in the vertical direction Z. With this configuration, the protector 1 and wire harness WH can smoothly connect the end wall part 33 by the first end wall part 31d and the second end wall part 32c without providing a step or the like in the extension direction X that intersects with the vertical direction Z in the end wall part 33, thereby improving the design of the rotating part 3.

In the protector 1 and wire harness WH of this embodiment, the rotating part 3 protrudes upward from the tube part 30 in the vertical direction Z and has a cylindrical part 35 that communicates with the internal space 36 of the tube part 30 and through which the wiring material W is inserted, and the base part 2 has a second bearing part 23 with a long hole 23a that supports the cylindrical part 35 rotatably around the rotation center Ax1 and slidably along the extension direction X. With this configuration, the protector 1 and wire harness WH can support both sides of the rotating part 3 in the vertical direction Z by the second bearing part 23 and the first bearing part 24, for example, so that the rotating part 3 can be rotated around the rotation center Ax1 and slid along the extension direction X more stably.

In this embodiment, the end wall portion 33 is configured to close the long hole 24a of the first bearing portion 24 when the shaft portion 34 is positioned at the first position P1, but is not limited to this example. For example, the end wall portion 33 may be configured to close the long hole 24a of the first bearing portion 24 when the shaft portion 34 is positioned at the second position P2, or when the shaft portion 34 is positioned at both the first position P1 and the second position P2.

Although the above is an example of an embodiment of the present invention, the above embodiment is merely an example and is not intended to limit the scope of the invention.
