  However, in the conventional apparatus for supplying power to the slide structure shown in FIG. 15, the slide door 81 is opened from the fully closed position shown in FIG. 15A to the fully opened position shown in FIG. ) The wire harness 84 is bent from the harness support 86 on the vehicle body 85 side with a small radius in the sliding door closing direction (a bent portion when fully opened is indicated by a reference numeral 84a), and the harness is applied to the swinging member 83 on the slide door side. For example, when the sliding door 81 is half-opened or fully opened, the bent portion 84a of the wire harness 84 protrudes greatly in the sliding door closing direction so that the step of the vehicle entrance / exit 87 is performed. There is a concern that it may be exposed to the top or the scuff plate, which may impair the appearance, and it may interfere with passengers getting on and off. Bending durability of the bent portion 84a of the wire harness 84 there is concern that serves to decrease with repeated opening and closing of the 81.

When the slide door 81 is opened as shown in FIG. 15B, the sliding door-side swing member 83 is rotated by an elastic member in the direction of arrow E in FIG. 15A (in the slide door closing direction). Therefore, when the slide door 81 is closed from the fully open position (particularly when it is half open), the wire harness 84 is not smoothly bent into a substantially S shape between the slide door 81 and the vehicle body 85. There was a concern that it would buckle or bend, and could be exposed to protrude greatly on the step or scuff plate of the entrance / exit 87 of the vehicle body 85.

  Each of the above-mentioned concerns can occur even when power is constantly supplied to a slide structure such as a slide door of a vehicle other than an automobile or a slide door of a vehicle other than a vehicle, such as a test device or a processing device. The vehicle body, the test apparatus main body, and the processing apparatus main body are collectively referred to as a fixed structure with respect to the slide structure.

  In view of the above, the present invention smoothly bends the wire harness with a large radius on the fixed structure side when the slide structure is opened and closed, and also connects the wire harness to the slide structure and the fixed structure when opening and closing the slide structure. Bends smoothly into a substantially S-shape between the wires to increase the bending durability of each wire harness and prevent the wire harness from being exposed to, for example, the entrance / exit of the fixed structure, thereby ensuring reliable power supply at all times. It is an object of the present invention to provide an apparatus for supplying power to a slide structure that can improve performance.

In order to achieve the above object, an apparatus for feeding power to a slide structure according to claim 1 of the present invention is for feeding power to a slide structure in which a wire harness is routed from a feeder on the fixed structure side to the slide structure.

In addition , when the slide structure opens from fully closed to half open, the second spring member forces the swinging member of the power feeder on the fixed structure side from the rotation start position to the specified angle with a positive biasing force. Rotate in the opening direction of the slide structure, and move the harness part near the fixed structure of the wire harness together with the swinging member away from the fixed structure in the opening direction of the slide structure. The urging force in the direction prevents further swinging of the swinging member and maintains the swinging member at a specified angular position. As a result, when the slide structure is half-opened, the harness portion near the fixed structure of the wire harness is prevented from projecting and being exposed to, for example, the entrance / exit of the fixed structure (on the vehicle body entrance / exit step or on the scuff plate). In addition, the harness portion near the fixed structure bends with a large radius, and the wire harness bends smoothly in a substantially S shape between the fixed structure and the slide structure (attachment of the second spring member).

An example will be described in which the left sliding door of the automobile is used as the sliding structure and the vehicle body of the automobile is used as the fixed structure.

  As shown in FIG. 1, when the sliding door 2 is fully closed as shown in FIG. 1, the device 1 for feeding power to the slide structure is provided with the corrugated tube 6 of the wire harness from the feeding tool 4 on the vehicle body 3 side to the feeding tool 5 on the sliding door side. The cable is pulled by pulling it in a slightly diagonal direction toward the front outer side of the vehicle, and the neck of the power supply device 4 on the vehicle body side from when the slide door 2 of FIG. 1 is fully closed to when the slide door 2 of FIG. The swinging member 7 is a sliding door from the rotation starting end position (position of 0 ° in FIG. 3) to the specified angle α by the positive biasing force F1 of the second spring member 8 (see FIG. 6) with the shaft portion 12 as the center. The urging is performed so as to rotate counterclockwise in the opening direction (rear of the vehicle) (the urging of the swinging member 7 in the positive direction by the second spring member 8 is completed at a predetermined angle α), and FIG. For example, when the sliding door 2 is maintained in a half-open state (wire (When the external force such as the tensile force in the sliding door opening / closing direction is not applied to the corrugated tube 6 of the lane), the first spring member around the shaft portion 12 is used as the swing member 7 of the power supply device 4 on the vehicle body side. 9 (see FIG. 6) with a reverse biasing force F2 of 9 (see FIG. 6) from the rotation end position (position 90 ° in FIG. 3) to the specified angle α in the reverse direction, that is, in the clockwise direction to rotate in the sliding door closing direction. (The reverse biasing of the swinging member 7 by the first spring member 9 is completed at a predetermined angle α, and the swinging member 7 is still biased in the reverse direction by the first spring member 9). A state in which the swinging member 7 of the power supply tool 4 on the vehicle body side is neutral between the positive biasing force of the second spring member 8 and the reverse biasing force of the first spring member 9. To do.

  In the above, the swinging member 7 of the power supply tool 4 on the vehicle body side at the specified angle α in FIG. 3 applies the biasing force in the forward direction of the second spring member 8 and the reverse biasing of the first spring member 9. Although it has been described that the urging force is not urged together (the urging has been completed), for example, the urging force in the positive direction (pre-loading) immediately before the oscillating member 7 urges the second spring member 8 is completed. And the first spring member 9 is biased in the opposite direction by the biasing force (preload) in the opposite direction immediately before the biasing is completed, and the swinging motion is performed in a state where the biasing forces of the two spring members 8 and 9 are balanced. The member 7 may stop at a predetermined angle α position. In FIG. 1, reference numerals 19 and 45 denote fixing members on the fixed side of the power feeders 4 and 5.

  In the example of FIG. 3, the prescribed angle α is approximately 45 °, and the maximum swing angle of the swing member 7 is approximately 90 °. In FIG. 3, the position of the swinging member 7 when the slide door 2 is fully closed (rotation start position) is 0 °, and the position of the swinging member 7 when the slide door 2 is fully open (rotation end position) is 90 °. Is shown.

  Moreover, in FIGS. 1-5, the substantially plate-shaped harness guide part 10 (refer FIG. 6) which is a part of the swing member 7 is illustrated. The second spring member 8 and the first spring member 9 may be coil springs as described later, or may be leaf springs, coil springs, spiral springs, or the like. As the sliding door 2 is opened as shown in FIG. 2 after the sliding door 2 of FIG. 1 is fully closed, the sliding door (sliding structure) 2 is separated from the vehicle body (fixed structure) 3 to the outside of the vehicle at the initial opening. Then, it slides back along the outer surface of the vehicle body 3.

  As shown in FIG. 2, when the sliding door 2 is half open (in FIG. 2, the sliding door 2 is opened by moving with a stroke smaller than half the full stroke from the closed state in FIG. When the half-stroke is half-opened, the following description is the same), and the urging force of the second spring member 8 forces the swinging member 7 on the vehicle body side counterclockwise in the sliding door opening direction. By rotating, the wire harness portion (corrugated tube portion) 6a near the vehicle body 3 integrally with the swing member 7 is separated from the vehicle body 3 counterclockwise in the sliding door opening direction with the power supply tool 4 as a fulcrum. Then, the middle bent portion 6b (corresponding to the vehicle body) of the corrugated tube 6 of the wire harness is rearward (sliding) from a step or scuff plate (not shown) of the vehicle entrance / exit 11. Spaced in the direction) open A.

  This prevents the middle bent portion 6b (corresponding to the vehicle body) of the corrugated tube 6 of the wire harness from being exposed on the step or the scuff plate, and shifts to the half-open state of the slide door 2 of FIGS. When the corrugated tube 6 of the wire harness is bent (between the vehicle body), the bent portion 6b is bent at a large radius, and the bent portion 6b of the corrugated tube 6 of the wire harness is repeatedly opened and closed as the sliding door 2 is repeatedly opened and closed. The bending durability is improved.

  4 in a half-open state (moves backward to approximately half the full stroke of the slide door 2 so that the vehicle body-side power supply 4 and the slide door-side power supply 5 are in the door thickness direction, that is, the vehicle left and right. A third spring having a spring force (spring constant) weaker than the spring force (spring constant) of the first spring member 9 (FIG. 6) of the power supply tool 4 on the vehicle body side in a state substantially facing or close to the direction). The member 13 (see FIG. 9) is provided in advance on the power supply 5 on the slide door side (the spring force of the first spring member 9 is set stronger than the spring force of the third spring member 13), The third spring member 13 biases the swinging member (second swinging member) 14 of the power supply tool 5 on the slide door side with a biasing force F3 so as to rotate clockwise in the sliding door opening direction. .

Thus, when the sliding door 2 of FIG. 4 is half open, the swinging member 7 on the vehicle body side is maintained at the position of the prescribed angle α in the state of FIG. 2 (rear of the wire harness portion 6a near the vehicle body 3). And the swinging member 14 on the sliding door side is rotated clockwise as indicated by an arrow F3 together with the wire harness portion (corrugated tube portion) 6c near the sliding door 2). Thus, the corrugated tube 6 of the wire harness is smoothly bent into an approximately S shape between the sliding door 2 and the vehicle body 3.

  This prevents the corrugated tube 6 of the wire harness from buckling or bending between the sliding door 2 and the vehicle body 3 when the slide door 2 of FIG. Problems such as damage to the wire harness due to buckling or bending and problems such as the buckling portion or bending portion of the wire harness protruding and being exposed on the step of the elevator 11 or on the scuff plate are prevented.

Then, by further sliding the sliding door 2 in the opening direction (rearward) from the half-opened state of the sliding door 2 in FIG. 4, the corrugated tube 6 of the wire harness moves backward (sliding door) with the power supply 5 on the sliding door as a fulcrum. Is pulled in the opening direction), and the tensile force overcomes the reverse biasing force F2 of the first spring member 9 (FIG. 6) of the power supply device 4 on the vehicle body side, so that the wire harness portion (corrugated) near the vehicle body 3 The swinging member 7 on the vehicle body side integrally rotates with the tube portion 6a and rotates counterclockwise in the sliding door opening direction, so that the sliding door 2 of FIG. 5 is fully opened.

  In FIG. 5, for example, the first spring member 9 (FIG. 6) is pushed in the direction opposite to the direction of the biasing force F2 and bent in the compression direction, and the second spring member 8 (FIG. 6) is biased by the biasing force F1 (FIG. 6). It is also possible to bend in the extension direction by being pulled in the direction of FIG. Since the corrugated tube 6 of the wire harness is pulled forward of the vehicle toward the power supply 4 on the vehicle body side, the third spring member 13 (FIG. 9) opposes the urging force F3 in the direction opposite to the urging direction. Pulled and bent, the swinging member 14 on the sliding door side rotates counterclockwise integrally with the wire harness portion (corrugated tube portion) 6 c near the sliding door 2 around the shaft portion 15.

  Since the swinging member 7 on the vehicle body side of the present example has a substantially plate-shaped harness guide member 10, the harness guide member 10 protrudes in the thickness direction of the sliding door in a direction orthogonal to the vehicle body 3, and the harness guide A wire harness portion (corrugated tube portion) 6a near the vehicle body 3 along the member 10 is separated from the vehicle body 3 toward the slide door 2 side, and the vehicle body portion 3a and the wire harness in the vicinity of the rear of the power feeder 4 on the vehicle body side. (This configuration was previously proposed in Japanese Patent Application No. 2011-277107 by this applicant).

  1 to 5, the sliding door 2 is fully closed to fully opened. However, even when the sliding door 2 is fully opened to fully closed, the reverse action of FIGS. (The operation of FIG. 1) has the same effect.

FIG. 14 shows a fully opened state of the slide door 2, and FIG. 13 shows a substantially 3/4 opened state between FIG. 12 and FIG.

  In each figure, the chain line 6 ′ is not subjected to stepwise biasing, that is, angle regulation (second spring member) by the second spring member 8 and the first spring member 9 of the power feeder 4 on the vehicle body side. 8 and the intermediate member 21), the first spring member 9 urges the swinging member 7 on the vehicle body side clockwise in the sliding door closing direction, and the third spring member 13 A state in which the swinging member 14 is urged clockwise in the sliding door opening direction is shown for comparison.

  When the slide door 2 of FIG. 10 is fully closed, the corrugated tube 6 of the wire harness is pulled forward (sliding door closing direction) with the power supply device 4 on the vehicle body side as a fulcrum, and the swing member of the power supply device 4 on the vehicle body side 7 tilts clockwise around the shaft portion 12, and the corrugated tube 6 of the wire harness is inclined toward the power supply 5 (FIG. 11) on the sliding door side along the harness guide member 10 of the swinging member 7. It is routed almost straight forward.

  Since the swinging member 7 is biased counterclockwise by the second spring member 8 (FIG. 7), compared to the harness locus of the chain line 6 ′ not using the second spring member 8, the sliding door 2 ( When the corrugated tube portion 6 of the wire harness near the vehicle body 3 is easily rotated in the direction away from the vehicle body 3 at the initial opening of FIG. 11), the corrugated tube 6 of the wire harness when the sliding door is half-opened (FIG. 12). Motivation for a substantially S-shaped bending motion is provided.

  When the sliding door 2 of FIG. 11 is half open halfway, the second spring member 8 (FIG. 7) of the power supply 4 on the vehicle body side rotates the swinging member 7 counterclockwise around the shaft portion 12 by its biasing force. The corrugated tube portion 6a of the wire harness extends from the swinging member 7 in a curved shape with a large radius that is substantially straight in a direction substantially orthogonal to the thickness direction of the slide door 2. There is a concern that the wire harness part (corrugated tube part) 6a protrudes and is exposed on the step of the entrance / exit 11 of the vehicle body 3 or on the scuff plate by being pushed downward, and the bending durability of the corrugated tube part 6a is reduced. Is resolved. The corrugated tube portion 6a closer to the vehicle body is curved in a shape closer to a straight line with a larger radius than the harness locus of the chain line 6 'that does not use the second spring member 8.

  In FIG. 11, the third spring member 13 (FIG. 9) of the power supply tool 5 on the slide door side swings the corrugated tube portion (wire harness portion) 6 d near the slide door 2 of the wire harness around the shaft portion 15. By rotating clockwise with the member 14, the corrugated tube portion 6a on the vehicle body side is promoted (promoted) to be pushed downward while extending substantially straight in a direction substantially orthogonal to the thickness direction of the slide door 2. ing.

  When the sliding door 2 shown in FIG. 12 is half open halfway, the first spring member 9 (FIG. 7) of the power feeder 4 on the vehicle body side is subjected to a strong initial spring force (a spring force before or before the deflection). Since the swinging member 7 is pushed forward in the clockwise direction to prevent the swinging member 7 from rotating counterclockwise in the backward direction, the third spring member 13 of the power supply tool 5 on the slide door side (FIG. 9). The state in which the swinging member 14 is rotated clockwise by the urging force is maintained.

  As a result, the corrugated tube 6 of the wire harness is smoothly and beautifully bent into an approximately S shape between the power supply device 4 on the vehicle body side and the power supply device 5 on the slide door side. Buckling and bending are prevented, the bending durability of the wire harness is increased, and the opening / closing operation force of the sliding door 2 is reduced, and the opening / closing operability of the sliding door 2 is increased. The corrugated tube portion (wire harness portion) 6a close to the vehicle body 3 is smoothly bent with a large radius as compared to the harness locus of the chain line 6 ′ that does not use the second spring member 8, and the first to third spring members By the action of 8, 9, and 13, the corrugated tube 6 of the wire harness is pushed further back between the power feeders 4 and 5, and the corrugated tube portion 6a is exposed on the step of the entrance 11 or on the scuff plate. It is prevented.

  When the sliding door 2 of FIG. 13 is half open, the corrugated tube 6 of the wire harness is pulled backward (in the direction of the power supply tool 5 on the slide door side), but the first spring member of the power supply tool 4 on the vehicle body side is pulled. 9 (FIG. 7) is stronger than the force of the third spring member 13 (FIG. 9) of the power supply 5 on the slide door side. The swinging member 14 of the power supply 5 is pulled by the corrugated tube 6 of the wire harness and rotated forward counterclockwise, and the swinging member 7 of the power supply 4 on the vehicle body side is half open in FIG. The corrugated tube portion 6a near the vehicle body 3 is bent with a large radius by the urging force of the second spring member 8 as compared with the harness locus of the chain line 6 ′, and is pushed downwards, The bending of the corrugated tube 6 To increase the durability, prevent projection of the corrugated tube portion 6a onto step on to scuff plate of entrance 11 (exposure).

  Further, in FIG. 13, the wire harness portion (corrugated tube portion) 6e near the slide door is urged to rotate backward and loosely by the third spring member 13 together with the swing member 14 of the power supply tool 5 on the slide door side. Thus, interference between the intermediate portion 6f of the corrugated tube 6 of the wire harness and the vehicle body portion 3a is prevented.

  When the slide door 2 of FIG. 14 is fully opened, the corrugated tube 6 of the wire harness is further pulled rearward, and the swing member 7 of the power supply tool 4 on the vehicle body side biases the first spring member 9 (FIG. 7). The wire harness part (corrugated tube part) 6a close to the vehicle body 3 protrudes in the thickness direction of the slide door 2 along the harness guide member 10 so that the rear vehicle body Interference with the part 3a is prevented. The swinging member 14 of the power supply 5 on the slide door side rotates further counterclockwise from the position orthogonal to the slide door 2 in FIG. 13 against the bias of the third spring member 13 (FIG. 9). doing. The harness guide member 10 of this example is rotated and stopped slightly behind the position orthogonal to the slide door 2.

  10 to 14, the sliding door 2 has been described from the fully closed state to the fully opened state. However, even when the sliding door 2 is fully opened to fully closed, the reverse action of FIGS. The operation and effect similar to those shown in FIG.

  In the above embodiment, the second spring member 8 is provided on the vehicle body-side power supply tool 4. However, for example, the spring force F3 of the third spring member 13 of the slide door-side power supply tool 5 is the vehicle body. If the frictional resistance force when the swinging member 7 of the power feeding device 4 on the side is sufficiently larger than the rotating frictional force, the swinging member 7 of the power feeding device 4 on the vehicle body side is forcibly almost forced when the sliding door 2 is opened. Since a force that opens from 0 ° to a predetermined angle α (about 45 °) is applied, depending on conditions, the second spring member 8 that regulates the predetermined angle α (about 45 °) from about 0 ° on the vehicle body side. It is also possible to omit (assuming urging force F1 = 0). In that case, the intermediate member 21 of FIG. 6 can be used as it is without the second spring member 8.

  In order to reliably and smoothly turn the swinging member 7 on the vehicle body side counterclockwise in the sliding door opening direction at the initial opening of the sliding door 2, it is preferable to use the second spring member 8. A second spring member 8 that urges the swing member 7 in the forward direction from approximately 0 ° to a specified angle α (approximately 45 °), and the swing member 7 from approximately 90 ° to a specified angle α (approximately 45 °). The effect of the first spring member 9 urging in the opposite direction to the position of the first spring member 9 and the effect of making the spring force of the first spring member 9 stronger than the spring force of the third spring member 13 The effect is more reliably exhibited than when the second spring member 8 is omitted.

  Moreover, in the said embodiment, although demonstrated using the example which used the corrugated tube 6 which can be bent in a horizontal direction as a harness protection tube (exterior member) of a wire harness, it is a wire between the slide door 2 and the vehicle body 3. FIG. If it is possible to prevent the harness from drooping, or if the wire harness has a short overall length and there is no fear of drooping, it is also possible to use a harness protection tube other than the corrugated tube 6, other droop prevention members, or the like. In the said embodiment, although the corrugated tube was shown with the code | symbol 6, you may show the wire harness itself (for example, consisting of a harness protection tube and a plurality of electric wires) with the code | symbol 6. FIG.

  The apparatus for supplying power to the slide structure according to the present invention smoothly bends the wire harness with a large radius on the fixed structure side when the slide structure is opened and closed, and the wire harness is fixed to the slide structure and the structure when the slide structure is opened and closed. Bending with the body smoothly in an approximately S-shape increases the bending durability of each wire harness and prevents the wire harness from being exposed to, for example, the entrance / exit of the fixed structure.
