Description

  The present invention relates to a constant power supply device in which, for example, a surplus length absorbing mechanism for a wire harness is provided on both a slide door and a vehicle body of an automobile.

  8 to 9 show an embodiment of a conventional constant power supply device (see Patent Document 1).

  The constant power supply device 61 includes a horizontally long guide member 63 provided on a slide door 62 of an automobile, a slider 64 slidably engaged with a rail portion of the guide member 63, and a shaft portion perpendicular to the slider 64 in a horizontal direction. A swinging member 65 (FIG. 9) supported in a swingable manner on the inside of the guide member 63, and bent and arranged in a substantially U shape, and bent from the swinging member 65 to the vehicle body (not shown). A caterpillar-shaped harness exterior member 66 that is freely routed is provided.

  The exterior member 66 is covered with a tube 67 between the slide door 62 and the vehicle body (transition space). A plurality of electric wires (wire harnesses) 68 (FIG. 9) are inserted inside the exterior member 66 and the slider 64.

When the sliding door 62 is opened in the direction of arrow A (rear of the vehicle) from the state of FIG. 8, the slider 64 moves relatively forward along the guide member 63, and the wire harness 68 and the exterior member 66 move inside the guide member 63. Elongates in an approximate J shape. When the sliding door 62 is opened and closed, the wire harness 68 expands and contracts together with the exterior member 66, so that the harness surplus length is absorbed.
Japanese Patent Laying-Open No. 2003-25850 (FIGS. 2 and 4)

  However, in the conventional constant power supply device 61 described above, the space on the slide door side is used to absorb the harness extra length in a state where the wire harness 68 is folded in a substantially U shape on the slide door 62 side while being folded horizontally. There is a concern that the layout of other structures and accessories may be limited.

  Further, since the wire harness 68 bends in a substantially V shape at a small angle from the slider 64 to the swing member 65 when the slide door 62 is opened and closed, a large bending stress acts on the bent portion 68a of the wire harness 68, and the harness There were also concerns that the extra length absorbing operation may be lacking in smoothness or the durability of the wire harness 68 may be reduced. In addition, there is a concern that the use of an expensive and heavy caterpillar-shaped exterior member 66 in order to regulate the direction (path) of the wire harness 68 increases the cost and weight of the structure.

  Each of the above-mentioned concerns is not limited to the slide door 62 of the automobile, but also occurs when the above-described power supply device is applied to a slide structure such as a slide door of a vehicle other than the automobile or a slide door of a processing machine. To get.

The wire harness introduction direction and the lead-out direction are defined in a state where the wire harness is tilted in the harness lead-out direction and is in contact with the stopper portion, and the wire harness is introduced or led out while being bent at a large radius along the arc-shaped roller.

  According to the first aspect of the present invention, the power supply device on the slide structure side is reduced in size and space-saving by a simple structure in which the wire harness is swung on the slide structure side. The layout space for electrical components and the degree of freedom in layout are expanded. In addition, the simple structure of swinging and accommodating the wire harness allows the harness surplus length to be absorbed smoothly and reliably without being caught or broken, and the harness surplus length absorbing structure can be reduced in cost.

  According to the second aspect of the present invention, the harness holding member moves along the guide portion to absorb the harness surplus length, so that it is possible to cope with an increase in the harness surplus length and a slide structure with a large slide amount. It becomes possible to correspond to the body. In addition, the power feeding device can be used in common from a small slide amount to a large slide amount of the slide structure, and the product cost is reduced.

  According to the invention described in claim 3, since the wire harness is not subjected to a large bending load, the durability of the wire harness is improved, and the operation from bending to extension of the wire harness is smoothly and reliably performed with a small force. , Reliability of constant power supply increases.

  According to the invention of claim 4, the wire harness can be introduced into the surplus length absorbing portion and the wire harness from the surplus length absorbing portion can be smoothly introduced with a large bending radius when the slide structure is opened and closed. The extra length absorbability and bending durability of the harness are improved.

  According to the fifth aspect of the present invention, the wire harness slides with low friction along the roller, so that the wear of the wire harness is prevented and the wire harness is led out from the surplus length absorbing portion and the surplus length is absorbed. The wire harness is smoothly introduced into the part with a small force, and the extra length absorbability of the wire harness and the reliability of constant power supply are improved.

  According to the sixth aspect of the present invention, the second power feeding device is miniaturized by using an arc-shaped roller instead of a circle, and the arc-shaped roller is tilted so that the extra length accommodating portion can be reduced. The introduction direction and the lead-out direction of the wire harness are defined by a large bending radius, so that the harness surplus length is absorbed smoothly and reliably, and the surplus length absorbability is increased.

Is pivotally supported. The circular roller 17 is supported by a central shaft portion 36, the substantially semicircular roller 18 is supported by a central shaft portion 37, and the shaft portions 36 and 37 are located outside the case 16.

  The outer peripheral surfaces 17a and 18a of the rollers 17 and 18 protrude inside the constricted portion 29, and the wire harness 21 is supported by the rollers 17 and 18 with low friction instead of the constricted portion 29 (case 16). The constricted portion 29 of the case 16 is provided with an opening 38 through which the rollers 17 and 18 protrude inward. Each shaft portion 36, 37 is supported at both ends of the shaft portion by, for example, horizontal upper and lower wall portions integral with the case 16 (only the lower wall portion is indicated by reference numeral 39). The case 16 and the rollers 17 and 18 are preferably configured as an integral unit.

  The semicircular roller 18 has an arcuate outer peripheral surface 18a, a short straight face 18b that intersects the arcuate outer peripheral face 18a and continues to the back, and a long straight face 18b and a long continuous face that intersects the outer peripheral surface 18a. And face-to-face 18c. By forming the short true face 18b, the radius of the arc-shaped outer peripheral surface 18a is largely defined. The long straight face 18c is exposed to the outside (rear) of the case 16, and the rotation range is restricted by a substantially reverse-shaped stopper wall (stopper portion) 40 (FIG. 4) on the rear side.

  The stopper wall 40 is preferably provided integrally with the case 16 like the roller 18. The substantially inverted V-shaped stopper wall 40 has an inclined inner half portion 40 a and an outer half portion 40 b that substantially follow the curved shape of the constricted portion 29 until the semicircular roller 18 abuts against the stopper wall 40. It rotates (tilts) substantially along the curved shape of the constricted portion 29.

  The harness fixing portion 35 is led out to the front of the vehicle body 7 while fixing the wire harness 21. The wire harness 21 is connector-connected to a wire harness (not shown) on the vehicle body side outside the harness fixing portion 35. A connector may be used as the harness fixing portion 35.

  The wire harness 21 of this example is composed of a plurality of electric wires and a synthetic resin corrugated tube (protective tube) 15 covering the wires, and the harness fixing portion 35 is formed in a circumferential groove (not shown) of the corrugated tube 15. It has a rib (not shown) to be engaged and is formed in a split manner. A corrugated tube 15 having a circular cross-section or a flat shape (oval cross-section) is used. Only the electric wire is led out of the case 16 from the harness fixing portion 35.

  The operation of the above-described constant power supply device 1 will be described below with reference to FIGS. 4 to 7 show the configuration of FIG. 1 in the order of operation.

  As shown in FIG. 4, when the slide door 4 is moved forward and fully closed, the slider 5 of the first power feeding device 2 on the slide door side is located on the rear end side of the guide rail 23, and the swinging member 6 faces the rear stopper 20 and faces backward, and the wire harness 21 extends from the swinging member 6 to the front harness fixing portion 35 through the opening 28 of the case 16 of the second power feeding device 3 on the vehicle body side. While being bent in a substantially U shape, it is supported by a circular rotatable roller 17 on the front side of the opening 28.

  That is, the wire harness 21 is pulled out toward the first power supply device 2 on the other end side using the harness fixing portion 35 on one end side and the intermediate circular roller 17 as a fulcrum, and the inclined wall portion 32 and the opening portion of the case are opened. 28 along the curved wall 30 on the front side. It goes without saying that the wire harness 21 is pulled with a certain degree of slack (margin).

  When the sliding door 4 is opened from the fully closed state of FIG. 4 as shown in FIG. 5, the sliding door 4 follows a two-dimensional guide rail (not shown) of the vehicle body 7 at the initial opening stage. It moves away from the vehicle body 7 while moving backward.

  The slider 5 of the first power feeding device 2 moves slightly rearward along the guide rail 23, the swinging member 6 rotates slightly diagonally as indicated by an arrow A toward the vehicle body 7, and the wire harness 21 swings. Between the member 6 and the harness fixing portion 35 of the second power feeding device 3, it slides with low friction along the front circular roller 17 while being bent in a substantially U shape with a radius larger than that of FIG. 17 is rotated in the direction of arrow B), and separated from the circular roller 17 and the front wall 30 and the inclined wall 32 of the opening 28 of the case, the rear semicircular roller 18 is separated. Along the direction of the arrow C, it is slidably guided into the case 16.

  When the sliding door 4 in FIG. 6 is half open (in a state where the sliding door 4 is more opened than in the half opening state in FIG. 5), the slider 5 moves to the front end side of the guide rail 23 and is positioned close to the opening 28 of the case 16; The swinging member 6 rotates toward the vehicle body 7 at an angle of 90 ° or less as shown by an arrow A, and the wire harness 21 is slidably guided from the swinging member 6 along the semicircular roller 18 on the rear side. Thus, it is almost completely accommodated in the extra length absorption space 27 of the case 16 as shown by an arrow C while being bent into a smooth substantially V shape with a radius larger than that in FIG. The wire harness 21 is bent in a circular arc shape with a relatively large radius without being bent in the case (the bent portion is indicated by reference numeral 21a), that is, on the inner wall surface of the case 16, that is, the rear wall portion 34 and the rear wall portion 32. Touch along smoothly.

  In FIG. 6, when the slider 5 is completely moved to the front end of the guide rail 23, the extra length absorption in the first power supply device 2 is completed, and the wire harness 21 is bent and accommodated in the case 16. The extra length absorption in the second power feeding device 3 is completed. The harness surplus length absorption in both the power feeding devices 2 and 3 is performed at the same time or almost at the same time (if anything, the first power feeding device 2 starts the surplus length absorption earlier). When the sliding door 4 is opened in FIGS. 5 to 6, the semicircular roller 18 contacts the inner half 40 a of the stopper wall 40 and tilts forward.

  The slider 5 is located at the front end of the guide rail 23 from the half-open state of the slide door 4 in FIG. 6 to the fully open position of the slide door 4 in FIG. The wire harness 21 is pulled out rearward from the case 16, and the rear semi-circular roller 18 rotates backward (tilts) counterclockwise as indicated by an arrow D. The front circular roller 17 is tilted backward while being in contact with the outer half portion 40b of the stopper wall 40, and the front circular roller 17 is freely rotated clockwise as indicated by an arrow E, thereby pulling out the wire harness 21 with low friction. In the case, the wire harness 21 is separated from the rear wall 34 as indicated by an arrow F, and is positioned along the inclined wall 32 with the harness fixing portion 35 as a fulcrum.

  In FIG. 7, the semicircular roller 18 is in contact with the wire harness 21 at the outer peripheral surface 18a having a large radius, and the wire harness 21 is smoothly bent with a large radius without bending. Since the shaft portion 37 is provided not at the radius center of the semicircular roller 18 but at the center, the roller 18 is rotated in a space-saving manner, and a large bending radius of the wire harness 21 is maintained. In FIG. 7, the wire harness 21 is routed in a substantially inverted S shape from the swinging member 6 to the harness fixing portion 35 along a locus that does not apply a large tensile load or bending load.

  When the slide door 4 is closed after the slide door 4 is fully opened in FIG. 7, the extra length of the wire harness 21 is absorbed by an operation reverse to the above as shown in FIGS. 6 to 4. It goes without saying that the extra length of the wire harness 21 is generated and absorbed when the slide door 4 between FIGS.

  In the above-described embodiment, the guide rail 23 is used for the first power supply device 2 on the slide door side. However, for example, the guide rail 23 is eliminated, and the slider (block portion) 5 is held together with the swinging member 6 and the harness. As the member 19 (FIG. 2), it is possible to swing integrally with the hanging portion 22 of the wire harness 21 along the door inner panel, or the slider (block portion) 5 of the harness holding member 19 is fixed to the door inner panel. It is also possible to absorb the surplus length only by the swinging motion of the swing member 6 (however, the surplus length absorption amount is small, so that it is limited to a slide door having a small slide stroke).

  In the above embodiment, in the second power supply device 3, the substantially U-shaped stopper wall 40 is used as the stopper portion for the semicircular roller 18. Pins and protrusions (not shown) can be provided.

  Further, instead of the semicircular roller 18, a circular roller 17 similar to the front side can be used. However, in this case, it cannot be denied that the roller 18 is enlarged. Further, since the rotation range, that is, the inclination angle is not restricted like the semicircular roller 18, the wire harness 21 is smoothly drawn in the inclination direction of the roller 18 in FIGS. 7, the effect of the wire harness 21 being pulled out smoothly in the direction of inclination of the roller 18 is reduced.

  In the above embodiment, the front and rear rollers 17 and 18 are disposed in the opening 28 of the case 16. However, for example, the rollers 17 and 18 may be eliminated and only the case 16 may be configured. In this case, the wire harness 21 smoothly slides along the inner surfaces 30a (FIG. 4) and 31a (FIG. 7) of the curved or inclined walls 30 and 31 of the opening 28, while FIGS. In FIG. 7, it is pulled into the case (pushed in), and in FIG.

  Moreover, in the said embodiment, although the electric power feeder 2 by the side of a sliding door was arrange | positioned vertically, when there is room of the space of the depth direction at the side of a sliding door, the electric power feeder 2 is connected with the electric power feeder 3 by the side of a vehicle body. Similarly, it can be arranged horizontally (horizontal).

  Moreover, although the said embodiment applies the electric power feeder 1 to the sliding door 4 of a motor vehicle, it is not restricted to the sliding door 4 of a motor vehicle, For example, sliding doors, such as vehicles other than a motor vehicle, a processing machine, etc. It is also possible to apply the above-described power supply device 1 to a slide structure such as (not shown). In this case, the vehicle body 7 and the processing machine main body are collectively referred to as a fixed structure.
