Description

  The present invention relates to a power feeding structure that feeds power to a moving body (that is, a lifting body) that is driven up and down such as a window glass of a vehicle.

  A window glass of a vehicle such as an automobile is provided with a defogger (anti-fogging) resistance circuit, an antenna circuit, a breakage detection circuit, and the like, and power is supplied to the window glass provided with these circuits. And what is shown to Fig.6 (a) and (b) is known as an electric power feeding structure for electrically feeding to the window glass driven to raise / lower.

  The power feeding structure shown in FIGS. 6A and 6B is a power feeding structure that feeds power to the window glass 102 that is disposed in the internal space of the door 101 and is driven up and down. In this power supply structure, the moving body side connector 105 provided on the window glass 102 and the door side connector 106 provided on the door 101 are connected by a power supply line to supply power to the window glass 102. As the window glass 102 moves up and down, the power supply line is slackened. If there is a lot of slackness, however, if it moves without any restriction, there is a risk that the window glass 102 will be bitten by the lifting mechanism. Therefore, in this power supply structure, slack in the power supply line is restricted by the surplus length absorber (power supply box) 103 disposed in the internal space of the door 101.

  The surplus length absorbing device 103 is configured to bend the power supply line in a U shape and accommodate it in the case 111 along the ascending / descending direction of the window glass 102. One end 104 of the power supply line is held by the sliding member 112, led out of the case 111, and connected to the moving body connector 105. The sliding member 112 is engaged with the case 111 so as to be movable in the up-and-down direction of the window glass 102, and the power supply line 104 follows up and down of the window glass 102 while moving the sliding member 112 up and down. As the sliding member 112 moves up and down, the power supply line in the case 111 becomes slack, but the slack is accommodated in the case 111 and prevents the window glass 102 from being caught in the lifting mechanism (for example, Patent Document 1).

JP 2005-57828 A

  By the way, in the conventional power feeding structure disclosed in Patent Document 1, in order to cope with the raising and lowering of the window glass 102, the feeding line is bent in a U shape and folded, and the case 111 extends along the raising and lowering direction of the window glass 102. Is housed in. In this case, the feed line needs to have at least a surplus length that is at least half the stroke (that is, the moving distance) of the window glass 102, and a relatively large amount of slack occurs in the feed line as the window glass 102 moves up and down. Therefore, the case 111 that accommodates the power supply line is necessary, and the case 111 is relatively large. However, since the internal space of the door 101 in which the window glass 102 and its lifting mechanism are accommodated is a space with a very limited capacity, it is difficult to secure an accommodation space for the large case 111. Moreover, when it is necessary to use the large case 111 as in the prior art, there is a problem that leads to an increase in cost.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a power supply structure that supplies power to a movable body that is driven to move up and down, and that is small, simple, and capable of reducing costs. And

In order to achieve the above-described object, the power feeding structure according to the present invention is characterized by the following (1) to (3).

(3) In the power feeding structure configured as described in (1) or (2) above,
The moving body is a window glass that opens and closes a window portion of a vehicle door, and the arm is a regulator arm of a window regulator.

According to the power supply structure having the above configuration (1), the power supply line is routed along the arm that drives the moving body to move up and down, and the movement of most of the power supply line can be restricted by the arm. And the raising / lowering of a moving body can respond | correspond by bending and deforming the one end part side of the electric power feeding line | wire which was derived | led-out from the front-end | tip part of the arm and was connected to the moving body. Here, the power supply line routed from the power supply line lead-out point at the tip of the arm to the connection point of the power supply line at the moving body is slackened as the mobile body is raised or lowered. Since the stroke of the part can be made relatively small compared to the stroke of the moving body, compared to the case where the extra length must be secured according to the stroke of the moving body as in the past, the arm tip side Therefore, it is possible to reduce the extra length necessary for the power supply line routed between the lead-out point and the connection part on the moving body side, and to reduce slack in the power supply line.

The feeder lines from the lead-out location to the connection location can be routed so as not to overlap in the thickness direction of the moving body. Therefore, it is possible to realize a compact and compact power supply structure that does not take up extra space in the thickness direction of the moving body, and to improve the bending performance of the extra length of the power supply line while avoiding interference with surrounding parts. Can be achieved. In addition, since the feeding structure does not increase the dimension of the moving body in the thickness direction, it is possible to contribute to a reduction in the thickness of a portion (for example, a vehicle door) equipped with the moving body.

  The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by reading through the best mode for carrying out the invention described below with reference to the accompanying drawings.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings.

  1 is a sectional view of a door of an automobile to which a power feeding structure according to the present invention is applied, FIG. 2 is a front view showing a window glass lifting mechanism of the door of FIG. 1, and FIG. 3 is a partial configuration of the lifting mechanism of FIG. FIG. 4 is a front view showing one embodiment of the power feeding structure of the present invention, and FIGS. 4A to 4C are front views showing an enlarged detailed configuration of the power feeding structure of FIG. 4A is a state when the window glass is fully opened, FIG. 4B is a state when the window glass is half-opened, and FIG. 4C is a state when the window glass is fully opened. The closed state is shown, and FIG. 5 is a view taken along the arrow V in FIG.

  As shown in FIGS. 1 and 2, the power supply structure of the present embodiment is provided on a door of an automobile and supplies power to a window glass (moving body) that is disposed on the door and is driven up and down. . Below, the raising / lowering mechanism of a window glass is demonstrated.

  The door panel 1 is formed by joining a press-molded outer panel 3 and an inner panel 4 to form a predetermined space therein.

  The window glass 2 is interposed between the outer panel 3 and the inner panel 4 and is driven up and down in a substantially vertical direction by a lifting mechanism described later. As a result, the window glass 2 appears outside the door panel 1 through a gap between the outer panel 3 and the inner panel 4 corresponding to the upper edge of the door panel 1, and enters the internal space of the door panel 1.

  Between the window glass 2 and the outer panel 3, a pair of glass guides 5, 5 extending in a substantially vertical direction are provided with a predetermined distance in the front-rear direction. The lower end edge of the window glass 2 is engaged with a pair of glass guides 5 and 5 so that the window glass 2 is guided to move in a substantially vertical direction.

  In the internal space of the door panel 1, a window regulator (that is, an elevating mechanism) 6 that drives the window glass 2 to move up and down is disposed.

  The window regulator 6 is a so-called X-arm type window regulator, and includes a base plate 11 fixed to the door panel 1, a main arm 12 supported by the base plate 11, and a pair of supports supported by the main arm 12. Auxiliary arms 15 and 16.

  As shown also in FIG. 3, the main arm 12 is rotatably supported by the base plate 11 via a rotating shaft 13 provided at the base end portion thereof. The leading end of the main arm 12 is fixed to the lower edge of the window glass 2 and engaged with a rail 14 extending in the vehicle front-rear direction via a roller. The leading end of the main arm 12 extends along the rail 14. Can be moved substantially in the front-rear direction.

  One auxiliary arm 15 is on the front surface side of the main arm 12, and the other auxiliary arm 16 is on the back surface side of the main arm 12, and is arranged so as to extend in a straight line and intersect the main arm 12 in a substantially X shape. Has been. The pair of auxiliary arms 15 and 16 are supported at substantially the center in the longitudinal direction of the main arm 12 so that their base end portions are rotatable so as to rotate coaxially and integrally.

  Like the tip of the main arm 12, the tip of the auxiliary arm 15 is engaged with a rail 14 fixed to the lower edge of the window glass 2 and extending substantially in the front-rear direction via a roller. It can move along the front-back direction. The tip of the auxiliary arm 16 is fixed to the door panel 1 and engaged with a rail 17 extending in the front-rear direction in parallel with the rail 14 via a roller, and is movable in the front-rear direction along the rail 17. .

  The base plate 11 is provided with a drive mechanism (not shown). The drive mechanism includes a drive source (not shown) such as a motor and a manual handle, and a pinion gear (not shown) that rotates by the operation of the drive source. A sector gear (not shown) is fixed to the base end portion of the main arm 12 so as to rotate integrally. The sector gear meshes with a pinion gear of the drive mechanism.

  In the above configuration, when the drive source of the drive mechanism operates, the main arm 12 is rotationally driven and oscillated by the engagement of the pinion gear and the sector gear of the drive mechanism. As the main arm 12 swings, the tip of the main arm 12 moves back and forth along the rail 14 and moves the rail 14 up and down. Thereby, the window glass 2 moves up and down.

  The pair of auxiliary arms 15 and 16 are sandwiched between a rail 14 that moves up and down together with the window glass 2 and a rail 17 that is fixed to the door panel 1. Are rotated together while being moved back and forth along the axis to maintain the posture of the rail 14. Thereby, the window glass 2 moves up and down stably.

  A feeding line 20 for feeding power to the window glass 2 that is driven up and down is introduced from the vehicle body into the interior space of the door panel 1, routed along the main arm 12, and connected to the window glass 2. Specifically, the feeder 20 is fixed to the base plate 11 at a predetermined location, passes through the periphery of the rotating shaft 13 of the main arm 12, and avoids the rotating shaft of the auxiliary arm 16 on the back surface or side surface of the main arm 12. Along with this, it reaches the tip of the main arm 12, is led out from the tip of the main arm 12 and is connected to the lower edge of the window glass 2. The power supply line 20 between the lead-out point 21 on the front end side of the main arm 12 and the connection point 22 to the window glass 2 is bent in a substantially vertical plane with a slack.

  The power supply line 20 is routed so as to be able to be bent and deformed between the periphery of the rotation shaft 13 of the main arm 12 and the connection part 22 of the window glass 2 from the lead-out part 21 at the tip of the main arm 12. Except for these parts, the power supply line 20 is fixed to the back surface or the side surface of the main arm 12 in the whole region or a plurality of locations along the main arm 12. The fixing means is not particularly limited, and for example, an adhesive tape, a clip, or the like can be used. Note that a round electric wire or a flat electric wire can be used as the feeder line 20.

  FIG. 3 shows how the feeder 20 changes as the window glass 2 opens and closes. In the figure, A is the position when the window glass 2 is fully open, and B is the window glass 2 is fully closed. It shows the position when When the window glass 2 is fully opened, the main arm 12 swings downward, and the window glass 2 is lowered to the lower end position together with the rail 14. When the window glass 2 is fully closed, the main arm 12 swings upward, and the window glass 2 rises to the upper end position together with the rail 14. The moving direction of the window glass 2 during the raising / lowering operation is slightly inclined as indicated by an arrow Y in the figure.

  As shown in FIGS. 4A to 4C and FIG. 5, the lead-out location 21 of the power supply line 20 at the tip of the main arm 12 and the connection location 22 of the power supply line 21 in the window glass 2 are They are arranged on substantially the same plane in the thickness direction (the same as the thickness direction of the window glass 2). The lead-out location 21 of the power supply line 20 at the tip of the main arm 12 is located below the window glass 2 and below the connection location 22 of the power supply line 20 in the window glass 2 in the entire lifting area of the window glass 2. Are arranged as follows.

  In this case, a bracket 25 is attached to the distal end portion of the main arm 12, and the bracket 25 allows the lead-out location 21 of the feeder 20 at the distal end portion of the main arm 12 to be directly below the rail 14 at the lower end of the window glass 2. It is set to a position that goes around the position. The power supply line 20 led out from the lead-out location 21 makes a U-turn once in the middle and reaches the connection location 22 at the lower end of the window glass 2. In addition, in the connection location 22, the feeder 20 may be directly fixed to the lower edge part of the window glass 2, or may be fixed to a member attached to the window glass 2 such as the rail 14.

  Further, a protector 30 having an inverted U-shaped cross section is provided below the rail 14 at the lower end of the window glass 2. The protector 30 regulates the position of the feeder 20 in the door thickness direction from the lead-out location 21 to the connection location 22, and includes an upper wall 31 joined to the lower surface of the rail 14 and both ends of the upper wall 31 in the width direction. And a pair of side walls 32 that are suspended. The lower end edges 32 a of the side walls 32 are curled outward so that the power supply line 20 can be easily received in the protector 30.

  Next, the operation of the power feeding structure of the present embodiment will be described with reference to FIG. 3 and FIGS. In other words, FIG. 4A shows the state of the power feeding structure when the window glass 2 is fully opened, and FIG. 4B shows the state of the power feeding structure when the window glass 2 is half-opened. FIG. 4C shows the state of the power feeding structure when the window glass 2 is fully closed.

  When the main arm 12 is pivotally driven and pivoted upward from the state shown in FIG. 4A, as shown in FIGS. 4B and 4C, the main arm 12 The tip moves along the rail 14 and raises the rail 14. Thereby, the window glass 2 is raised and closed. The movable range of the lead-out portion 21 of the feeder 20 during this operation is a range indicated by H in FIG. 3 and is a very narrow stroke as compared with the stroke of the window glass 2.

  A predetermined extra length is set at the distal end portion of the feeder 20 that is led out from the distal end portion of the main arm 12 and connected to the window glass 2 in order to follow the movement of the distal end portion of the main arm 12 by bending deformation. As the lead-out location 21 at the tip of the main arm 12 and the connection location 22 in the rail 14 approach each other, the feed line 20 becomes slack. Here, when the swing range of the main arm 12 is, for example, 90 ° up and down with respect to a horizontal state, the front-rear stroke H of the front end of the main arm 12 is an abbreviation of the vertical stroke of the window glass 2. If the swing range of the main arm 12 is less than 90 ° in the vertical direction, the front-rear stroke of the front end of the main arm 12 is less than half of the vertical stroke of the window glass 2. Thus, since the front-rear direction stroke of the front end of the main arm 12 can be reduced with respect to the vertical stroke of the window glass 2, the extra length required for the end of the feeder 20 can be shortened. It is possible to reduce the slack that occurs at this end. Therefore, the power feeding structure can be reduced in size and simplified, which can contribute to cost reduction.

  Further, in this power feeding structure, the lead-out location 21 of the power supply line 20 at the front end of the main arm 12 and the connection location 22 of the power supply line 20 in the window glass 2 are substantially the same in the thickness direction of the door panel 1 (window glass 2). Further, the lead-out location 21 of the power supply line 20 at the front end portion of the main arm 12 is disposed on a plane, and the connection location of the power supply line 20 in the window glass 2 is below the window glass 2 in the entire lifting area of the window glass 2. Since the empty space below the window glass 2 is used effectively, the feeder line 20 from the lead-out location 21 to the connection location 22 is connected to the door panel 1 (window glass 2). Can be routed so that they do not overlap in the thickness direction.

  Therefore, an extra space is not required in the thickness direction of the door panel 1 (window glass 2), a small and compact power feeding structure can be realized, and the extra length of the feeder 20 while avoiding interference with peripheral components. The bending performance of the part can be improved. Further, by providing this power feeding structure, the dimension of the door panel 1 in the thickness direction is not increased, so that the door panel 1 can be made thinner. Moreover, since the extra length part of the feeder 20 is routed using the space below the window glass 2, the degree of freedom in handling the feeder 20 in the thickness direction of the door panel 1 is improved.

  Further, in the power feeding structure of the present embodiment, the main arm 12 is provided with a bracket 25 that turns the lead-out portion of the power feeding line 20 to a position just below the rail 14 at the lower end of the window glass 2 at the tip of the main arm 12. 12 can be forcibly guided to the most desirable position on the lower side of the window glass 2 by the shortest path, and the window of the power supply line 20 from the derivation point 21 to the connection point 22 can be forcibly guided. The bending operation accompanying the raising and lowering of the glass 2 can be performed smoothly.

  In addition, an inverted U-shaped protector 30 is provided below the rail 14 at the lower end of the window glass 2 so as to regulate the position of the feeder 20 from the lead-out location 21 to the connection location 22. 2 can regulate the deformed shape of the power supply line 20 associated with the raising and lowering of the window 2, can ensure the smooth bendability of the power supply line 20, and can interfere with the power supply line 20 associated with the raising and lowering of the window glass 2. Can be eliminated.

  In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

  For example, in the above-described embodiment, the application example of the X-arm type window regulator 6 including the main arm 12 and the pair of auxiliary arms 15 and 16 has been described. However, the single-arm type window regulator having only the main arm 12 is described. Can be applied similarly.
