Description

  The present invention relates to a power feeding structure for a movable body that feeds power to a movable body from a fixed portion.

  For example, components that move relative to the vehicle body (a movable body such as a sunroof, a sunshade, a side glass, and a seat) are mounted on the vehicle. Various structures have conventionally been proposed for power supply to such movable bodies. In Patent Document 1, as shown in FIGS. 14 to 17, the flat electric wire W, the first extra-length absorption guide case 100 fixed to the vehicle body side that is the fixed portion side, and the sunroof that is the movable body side are fixed. The flat electric wire W including the second excess length absorbing guide case 101 has one end connected to the vehicle body side and the other end connected to the sunroof side, and has a length capable of following movement of the sunroof. An elastic member 102 is disposed on the flat wire W so as to return linearly when bent.

  In the closed position of the sunroof, as shown in FIG. 14, the first excess length absorption guide case 100 and the second excess length absorption guide case 101 are folded. In this state, the flat electric wire W is arranged to be folded in the first excess length absorption guide case 100 and the second excess length absorption guide case 101. By this, the remaining length of the flat electric wire W is absorbed.

  At the open position of the sunroof, as shown in FIG. 15, the first excess length absorption guide case 100 and the second excess length absorption guide case 101 are separated from each other. In this state, the flat electric wire W is arranged more linearly than the characteristic of the elastic member 102 returning to the linear shape.

  At the tilt-up position of the sunroof, as shown in FIG. 16, the first excess absorption guide case 100 and the second excess absorption guide case 101 are folded with the second excess absorption guide case 101 lifted at one end side. It becomes an overlapping position. In this state, as shown in FIG. 17, the flat electric wire W is laid in a loose state in the first excess length absorption guide case 100 and the second excess length absorption guide case 101 so as to be folded. By this, the remaining length of the flat electric wire W is absorbed.

  However, in the power feeding structure for a movable body according to the conventional example, it is necessary to attach the first extra length absorption guide case 100 to the vehicle body side and attach the second extra length absorption guide case 101 to the sunroof side. There is a problem that the structure is also complicated.

  In addition, although a structure using a versatile electric wire without an elastic member may be considered unlike the above-mentioned conventional example, the structure is further complicated.

  Therefore, the present invention has been made to solve the above-described problems, and it is an object of the present invention to provide a power feeding structure for a movable body that is easy to install and can be simplified in structure as much as possible.

The present invention includes a rail member fixed to a fixed portion, a slider moving along the rail member, and a movable body supported by the slider, and supplies power to the movable body from the fixed portion side. In the feed structure for a movable body, one end is connected to the fixed portion side, the other end is connected to the movable body side, and an electric wire routed along the rail member and an extra-long portion of the electric wire can be routed Extra length distribution portion, a movable guide member for guiding the extra length portion of the wire to the extra length distribution portion along a predetermined route, and extra length of the wire in the extra length distribution portion And a biasing means for biasing the movable guide member in a direction for pulling in the long portion, and the extra length routing portion is formed in a path along which a portion other than the extra length of the electric wire of the rail member is routed The longitudinal direction of the rail member is the routing direction of the extra length portion of the electric wire A movable body feeding structure, characterized in that.

Before Symbol movable guide member include those wherein the rail member movement is freely disposed, guides the folding of the extra length portion of the wire to the portion other than the extra length of the wire. The movable guide member is connected to the movable body via the biasing means, and guides the extra length portion of the wire to be folded back with respect to a portion other than the extra length of the wire. The movable body includes one that is a sunroof.

  According to the present invention, when moving the movable body for increasing the extra length portion of the wire, the biasing portion of the biasing means pulls the extra length portion of the wire into the extra length distribution portion to reduce the extra length portion of the wire. At the time of movement, the excess length portion of the wire can be sent out from the excess length distribution section against the biasing force of the biasing means, and the excess length of the wire can be reliably absorbed. Then, for example, if the extra length distribution part is attached to the fixed part side, there is no need to attach parts to the movable body side, so the attachment is easy. The arrangement is simple, since only the movable guide member and the urging means for urging the movable guide member are disposed in the extra length distribution portion. From the above, it is possible to provide a movable body power supply structure which is easy to install and whose structure can be simplified as much as possible.

It is done. The pair of middle sliders 25 has a rotation support hole (in particular, no reference numeral) on the front end side of the vehicle and a longitudinally elongated cam hole 25b. The rotation pin 21 a of the front slider 21 is inserted into the rotation support hole of the middle slider 25 on the front end side of the vehicle. The cam pins 23 a of the rear slider 23 are inserted into the elongated cam holes 25 b of the middle sliders 25. The pair of middle sliders 25 move integrally with the pair of front sliders 21 in the movement in the vehicle longitudinal direction FR, and the pair of rear sliders 23 corresponds to the vehicle according to the position of the cam pin 23a in the cam hole 25b. It moves in the longitudinal direction FR and the vertical direction TB of the vehicle. With such a slider mechanism, the sunroof 30 closes the opening 3 as shown in FIG. 3A and closes the front of the opening 3 as shown in FIG. It can be shifted to a tilt up position where the rear is opened and an open position where the opening 3 is opened as shown in FIG. 3 (c).

  As shown in FIG. 1, the sunroof 30 is attached to the pair of middle sliders 25. The sunroof 30 has a laminated panel body (in particular, without a reference numeral) in which a transparent glass body and a light control panel are at least laminated. The light control panel is in an opaque state when no voltage is applied, and changes the transparency according to the applied voltage level when the voltage is applied. Power is supplied to the light control panel from the vehicle body side. This feed structure is described below.

  Each drive belt 40 is made of synthetic resin. Each of the drive belts 40 is in the form of a long rectangle having a vertically long cross section. On one surface of each drive belt 40, a tooth portion 40a is provided continuously in the longitudinal direction. Each drive belt 40 is disposed in the belt routing path 16 of the front frame 15 and the belt guide path 13 of the pair of rail members 11. Each drive belt 40 is a belt surrounding wall (in particular, no reference numeral) in the area of the belt distribution path 16 of the front frame 15 with the belt cover 46 and in the area of the belt guide path 13 of the rail member 11. In order to prevent buckling (flexural deformation) easily. Thus, even when the sunroof 30 is pushed backward from the front of the vehicle, the pair of drive belts 40 move only along a predetermined trajectory.

  One end of the pair of drive belts 40 is fixed to the pair of rear sliders 23 (one drive belt 40 is fixed to one rear slider 23 and the other drive belt 40 is fixed to the other rear slider 23), The other end side is not fixed to any member. In other words, it is considered as a free end.

  The actuator 49 (shown in FIG. 1) is fixed at a substantially central position in the vehicle width direction of the front frame 15. A pair of output gear portions (not shown) of the actuator 49 respectively mesh with the teeth portions 40 a of the pair of drive belts 40. The pair of output gear portions rotate in opposite directions. Thus, the pair of drive belts 40 move in opposite directions, and the pair of rear sliders 23 move in synchronization at the same position in the vehicle longitudinal direction FR.

  The deflector 50 includes a deflector main body 51 and a pair of swinging arms 52 rotatably supported at both left and right ends of the deflector main body 51. The deflector body 51 is disposed at the front end of the opening 3 of the ceiling panel 2 over the entire area in the vehicle width direction of the opening 3. The front end side of the deflector body 51 is formed in an arc shape. As a result, at the time of opening of the opening 3, strong wind from the outside does not directly enter the vehicle interior through the opening 3.

  The pair of swing arms 52 is rotatably supported by the pair of rail members 11. The deflector main body 51 is positioned from the standby position (the position shown in FIGS. 3A and 3B) below the opening 3 of the ceiling panel 2 by the movement of the pair of swing arms 52 and the opening 3 to the ceiling panel 2. It is displaceable between the windward avoiding positions (the position shown in FIG. 3C) projecting upward, and is biased toward the windy avoiding position by the spring force of the torsion spring 53. The deflector main body 51 is positioned on the slide track of the front slider 21. When the front slider 21 is in the closed position of FIG. 3A and in the tilt up position of FIG. 3B, the pair of swinging arms 52 is the front slider 21. And is positioned at the standby position against the spring force of the torsion spring 53. When the front slider 21 is in the open position shown in FIG. 3C, the deflector main body 51 is positioned at the windward position by the spring force of the torsion spring 53 without receiving the pressure from the front slider 21. .

  The water receiving member 60 is disposed on the rear end side of the opening 3 over the entire area of the opening 3 in the vehicle width direction. The water receiving member 60 includes a slide portion (not shown) slidably supported by the pair of rail members 11 and a water receiving main body 62 supported by the slide portion and having a water receiving groove (not shown); It has a pair of arm portions 63 fixed to both ends in the vehicle width direction of the water receiver main body 62. In the water receiving groove (not shown) of the water receiving main body 62, a drainage port 62a (shown in FIG. 1) is formed immediately above the drainage path 14 of the pair of rail members 11. The ends of the pair of arm portions 63 are rotatably supported by the middle slider 25. The water receiving member 60 follows the movement of the middle slider 25 in the vehicle longitudinal direction FR and the vertical movement of the rear end of the middle slider 25.

  In the closed position shown in FIG. 3A, the water receiving main body 62 of the water receiving member 60 is located at the rear end position of the opening 3 and the water etc. falling from the gap between the sun roof 30 and the ceiling panel 2 receive. The water receiving main body 62 is located at the rear end position of the opening 3 when the sunroof 30 is at the tilt up position in FIG. 3B, and receives water etc. dropped from the opening 3. The water receiver main body 62 is located at the retracted position inside the ceiling panel 2 when the sunroof 30 is at the open position shown in FIG. 3C. Water and the like received by the water receiving main body 62 falls from the drainage port (not shown) to the drainage passage 14 of the rail member 11 and flows through the drainage passage 14 of the rail member 11 to its front end or rear end. , (Not shown) by the drainage hose (not shown) to the outside.

  Next, the fixing structure of the drive belt 40 and the rear slider 23 will be described. As shown in detail in FIGS. 4 and 5, the rear slider 23 is composed of a resin block 26 and an insulating metal bracket 27 fitted thereto. The resin block 26 is disposed in the slide guide path 12. The resin block 26 is provided with one fitting protrusion 26 a and the metal bracket 27 is provided with two fitting protrusions 27 a. The two fitting projections 27 a of the metal bracket 27 are disposed on both sides of the fitting projection 26 a of the resin block 26 in the vehicle longitudinal direction FR. At one end side of the drive belt 40, fitting holes 44 are opened at positions corresponding to the fitting protrusions 26a, 27a. By fitting the fitting projections 26 a and 27 a of the resin block 26 and the metal bracket 27 into the fitting holes 44 of the drive belt 40, the drive belt 40 and the rear slider 23 are connected.

  Next, a power feeding structure from the vehicle body 1 side to the sunroof 30 will be described. As shown in FIG. 1 and FIG. 8 etc., one end is connected to the vehicle body 1 which is the fixed portion side, and the other end is connected to the sunroof 30 side which is the movable body side. The electric wire W arranged as described above and an extra-length absorbing mechanism 70 for absorbing the extra-long portion of the electric wire W are provided.

  In the electric wire W, a connector (not shown) on one end side is connected to a connector (not shown) on the vehicle body side, and a connector 91 on the other end side is connected to a connector (not shown) on the sunroof side.

  The extra-length absorbing mechanism 70 includes an extra-length distribution unit 71, a movable guide member 72 disposed in the extra-length distribution unit 71, and a coil spring 73 as biasing means for applying an urging force to the movable guide member 72. Have.

  The extra length distribution portion 71 is formed separately (by a separate member) from the rail member 11. The extra length routing portion 71 is disposed as a routing direction of the extra long portion of the electric wire W, which is a direction different from the longitudinal direction of the rail member 11 (the vehicle longitudinal direction), specifically, a direction orthogonal thereto. The extra length distribution unit 71 has an accommodation length capable of distributing the extra length portion of the electric wire W. The extra length distribution unit 71 is integrally formed with the drainage cap 18.

  The movable guide member 72 is disposed movably in the arrangement direction of the extra length portion of the electric wire W in the extra length distribution unit 71. The surface of the movable guide member 72 on the tip side is formed as a semicircular surface. The electric wire W drawn into the extra length routing portion 71 from the path of the rail member 11 is stretched over the semicircular surface of the movable guide member 72. As described above, when the extra length portion of the wire W is spanned by the movable guide member 72, the movable guide member 72 guides the extra length portion of the wire W to be routed along a fixed path.

  The coil spring 73 urges the movable guide member 72 in a direction in which the extra length portion of the electric wire W is drawn into the extra length routing portion 71.

  In the above configuration, when the actuator 49 is driven, the pair of drive belts 40 is moved to the same position in the vehicle longitudinal direction FR at one end side, and the sunroof 30 is shifted to the position of three patterns as shown in FIG. Can.

  In the process of moving the sunroof 30 in the sliding direction, when moving the sunroof 30 to increase the extra length of the electric wire W (for example, from the closed position of the sunroof 30 in FIG. 9A to the open position in FIG. 9B) At the time of movement), the extra length portion of the wire W is drawn into the extra length distribution portion 71 by the spring force of the coil spring 73. In the process of moving the sunroof 30 in the sliding direction, when moving the sunroof 30 to reduce the extra length of the electric wire W (for example, from the open position of the sunroof 30 in FIG. 9B to the closed position in FIG. 9A) At the time of movement), the extra length portion of the electric wire W is fed out from the extra length distribution portion 71 against the spring force of the coil spring 73. As a result, the remaining length of the wire W can be reliably absorbed while maintaining the straight distribution state except for the remaining length of the wire W.

  In this way, in the transition of the sunroof 30 of the three patterns, from the power source on the vehicle body 1 side, the lead wire (not shown) on the vehicle body side, the electric wire W, the lead wire of the sunroof 30 which is a movable body The sunroof 30 is always supplied with power via

  As described above, in the movable body power supply structure for supplying power to the sun roof 30 as the movable body from the side of the vehicle body 1 as the fixed portion, one end is connected to the side of the vehicle body 1 and the other end is connected to the sun roof 30 side. The wire W arranged along the rail member 11, the excess length distribution portion 71 capable of routing the excess length portion of the electric wire W, and the excess length portion of the wire W in the excess length distribution portion 71 are constant. The movable guide member 72 guides the wiring along the path, and the coil spring 73 biases the movable guide member 72 in the direction of drawing the extra length portion of the electric wire W into the extra length routing portion 71.

  Therefore, as described above, when the sunroof 30 is moved to increase the extra length of the wire W, the extra length of the wire W is drawn into the extra length distribution section 71 by the spring force of the coil spring 73 and the extra length of the wire W is removed. At the time of movement of the sunroof 30 to be reduced, the excess length portion of the wire W can be sent out from the excess length distribution portion 71 against the spring force of the coil spring 73, and the excess length of the wire W can be reliably absorbed. And if the extra-long distribution part 71 is attached to the vehicle body 1 side like this embodiment, since it is not necessary to attach components to the sunroof 30 side, attachment is easy. In the extra length routing portion 71, only the movable guide member 72 and the biasing means (the coil spring 73 as in this embodiment) are disposed, so that the structure is simple. From the above, it is possible to provide a movable body power supply structure which is easy to install and whose structure can be simplified as much as possible.

  The extra length routing portion 71 is formed separately (as a separate member) from the rail member 11, and a direction different from the longitudinal direction of the rail member 11 is disposed as the routing direction of the extra long portion of the electric wire W, and the movable guide member The reference numeral 72 is configured to move in the routing direction of the extra length portion of the electric wire W. Therefore, since the excess length absorption direction of the electric wire W can be installed in any direction other than the longitudinal direction of the rail member 11, the installation freedom of the excess length absorbing mechanism 70 is high.

(First Modification of Excess Length Absorbing Mechanism)
10 and 11 show a first modification of the extra length absorbing mechanism 70A. The extra length absorbing mechanism 70A of the first modification includes the electric wire W routed along the rail member 11, the extra length routing portion 71, the movable guide member 72, and the like in the first embodiment. And a winding spring 73A which is a biasing means.

  In the electric wire W, the connector 90 on one end side is connected to a connector (not shown) on the vehicle body side, and the connector 91 on the other end side is connected to a connector (not shown) on the sunroof side.

  The extra length distribution portion 71 is formed on a path (specifically, the slide guide path 12) on which a portion other than the extra length of the electric wire W of the rail member 11 is routed. In the extra length distribution portion 71, the longitudinal direction of the rail member 11 is set as the distribution direction of the extra long portion of the electric wire W. In other words, the extra length distribution unit 71 is disposed as a shared path that is a path along which a portion other than the extra length of the electric wire W of the rail member 11 is routed. The winding spring 73A biases the movable guide member 72 in a direction in which the extra length portion of the electric wire W is drawn into the extra length distribution portion 71 of the common path. Specifically, the extra length distribution unit 71 is located below the path along which the portion other than the excess length of the electric wire W is routed.

  A pair of slide grooves 80 are provided on both side walls of the rail member 11. A movable guide member 72 is disposed slidably in the rail member 11 along the pair of slide grooves 80. The movable guide member 72 is biased with the spring force of the winding spring 73A, and the electric wire W arranged on the rail member 11 is stretched. Thus, by the electric wire W being spanned by the movable guide member 72, the movable guide member 72 draws in the extra length portion of the electric wire W and guides it to route along a fixed path. Specifically, the movable guide member 72 guides the excess length portion of the electric wire W so as to fold over the portion other than the excess length of the electric wire W.

  When the sunroof 30 moves to increase the extra length of the wire W (direction B in FIG. 10), the extra length of the wire W is guided to the extra length distribution unit 71 by the spring force of the winding spring 73A. At the time of movement of the sunroof 30 to reduce the long part (C direction in FIG. 11), the extra long part of the wire W is sent out from the extra length arrangement part 71 against the spring force of the winding spring 73A. Can be absorbed reliably.

  Also in this first modification, as in the embodiment described above, it is possible to provide a movable body power supply structure that is easy to attach and whose structure can be simplified as much as possible.

  In the first modified example, the extra length routing portion 71 is formed in a path along which a portion other than the extra length of the electric wire W of the rail member 11 is routed. Therefore, since the path along which the portion other than the extra length of the electric wire W of the rail member 11 is routed is disposed as a common path, the extra length absorbing mechanism 70A can be installed in a small space.

(Second variation of excess length absorption mechanism)
12 and 13 show a second modification of the extra length absorbing mechanism 70B. The extra length absorbing mechanism 70B of the second modification includes the electric wire W routed along the rail member 11, the extra length routing portion 71, the movable guide member 72, and the like in the second embodiment. It has a coil spring 73 which is a biasing means.

  In the electric wire W, a connector (not shown) on one end side is connected to a connector (not shown) on the vehicle body side, and a connector 91 on the other end side is connected to a connector (not shown) on the sunroof side.

  As in the first modification, the extra length distribution portion 71 is formed in a path along which a portion other than the excess length of the electric wire W of the rail member 11 is routed. In the extra length distribution portion 71, the longitudinal direction of the rail member 11 is set as the distribution direction of the extra long portion of the electric wire W. In other words, the extra length distribution unit 71 is disposed as a shared path that is a path along which a portion other than the extra length of the electric wire W of the rail member 11 is routed.

  The movable guide member 72 is connected to the sunroof 30 side (specifically, the water receiving member 60 moving integrally with the sunroof 30) via a coil spring 73. Therefore, the movable guide member 72 can move on the rail member 11 following the movement of the sunroof 30. The movable guide member 72 receives the spring force of the coil spring 73 supported by the sunroof 30, and the electric wire W arranged on the rail member 11 is stretched. As the electric wire W is spanned by the movable guide member 72 in this manner, the movable guide member 72 guides the excess length portion of the electric wire W to be routed along a predetermined path. Specifically, the movable guide member 72 guides the excess length portion of the electric wire W so as to fold back the portion other than the excess length of the electric wire W.

  When moving the sunroof 30 to increase the extra length of the wire W (direction E in FIG. 13), the extra length of the wire W is guided to the extra length distribution section 71 by the spring force of the coil spring 73. At the time of movement of the sunroof 30 which reduces the portion (direction D in FIG. 12), the extra length portion of the wire W is sent out from the extra length distribution portion 71 against the spring force of the coil spring 73 to ensure the extra length of the wire W Can absorb.

  Also in this second modification, as in the embodiment described above, it is possible to provide a movable body power supply structure that is easy to attach and whose structure can be simplified as much as possible.

  In the second modified example, the extra length distribution portion 71 is formed in the rail member 11 as in the first modified example. Therefore, since the path along which the portion other than the extra length of the electric wire W of the rail member 11 is routed is disposed as the shared path, the extra length absorbing mechanism 70B can be installed in a small space.

  In the second modification, the movable guide member 72 is supported on the sunroof 30 via the coil spring 73, and the electric wire W is spanned over the movable guide member 72. Therefore, mounting is further achieved as compared with the first modification. The structure is simple as compared with the first modification, because it is simple and there is no need to process the rail member 11 as in the first modification.

(Others)
In the embodiment and the modification, the movable body is the sunroof 30, and the power feeding structure for the sunroof 30 has been described.
