Description

The present invention relates to a movable body power supply structure that supplies power from one of a fixed portion and a movable body to the other.

For example, a vehicle is equipped with a component (a movable body such as a sunroof, a sunshade, a side glass, and a seat) that moves with respect to a vehicle body. Various structures have been conventionally proposed for supplying power to such a movable body. In Patent Document 1, as shown in FIGS. 22 to 25, the flat electric wire W, the first extra length absorption guide case 100 fixed to the vehicle body side which is the fixed portion side, and the sunroof side which is the movable body side are fixed. The flat electric wire W including the second extra length absorption 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 that can follow the movement of the sunroof. As shown in FIG. 25, the elastic member 102 is arranged on the flat electric wire W so as to return to a straight line when bent.

In the closed position of the sunroof, as shown in FIG. 22, the first extra length absorption guide case 100 and the second extra length absorption guide case 101 are folded and overlapped. In this state, the flat electric wires W are arranged so as to be folded in the first extra length absorption guide case 100 and the second extra length absorption guide case 101. As a result, the extra length of the flat electric wire W is absorbed.

In the open position of the sunroof, as shown in FIG. 23, the first extra length absorption guide case 100 and the second extra length absorption guide case 101 are separated from each other. In this state, the flat electric wire W is arranged in a straight line because of the characteristic that the elastic member 102 returns to the straight line.

At the tilt-up position of the sunroof, as shown in FIG. 24, the first extra length absorption guide case 100 and the second extra length absorption guide case 101 are folded with one end side of the second extra length absorption guide case 101 raised. It becomes the position where it overlaps. In this state, as shown in FIG. 24, the flat electric wires W are arranged in the first extra length absorption guide case 100 and the second extra length absorption guide case 101 so as to be folded in a loose state. As a result, the extra length of the flat electric wire W is absorbed.

However, in the power feeding structure for a movable body of the conventional example, it is necessary to mount the first extra length absorption guide case 100 on the vehicle body side and the second extra length absorption guide case 101 on the sunroof side, so that the mounting work is troublesome. However, there is a problem that the structure becomes large.

Also, unlike the above-mentioned conventional example, a structure using a general-purpose electric wire without an elastic member is conceivable, but the structure becomes more complicated.

Then, this invention was made|formed in order to solve the above-mentioned subject, and it aims at providing the electric power feeding structure for movable bodies which can be attached easily and can be comprised compactly.

The present invention includes a rail member fixed to a fixed portion, a slider that moves along the rail member, and a movable body supported by the slider, and the fixed portion and the movable body from one to the other. In a power supply structure for a movable body that performs power supply, one end is connected to the fixed portion side, the other end is provided with an electric wire connected to the movable body side, and an extra length absorption mechanism for winding an extra length portion of the electric wire, The extra length absorbing mechanism has a rotating body having a winding portion that winds up one of the movable body side and the fixed portion side of the electric wire from a switching position in the winding direction in the middle of the electric wire, and the rotating body. The urging means for urging one of the movable body side and the fixed portion side in the winding direction of the electric wire, and the other electric wire on the movable body side or the fixed portion side from the switching location is wound up. the winding direction of the wire parts possess a twist blocking wire accommodating portion for accommodating a portion that is wound in the opposite direction of the winding direction, the rotating body includes the winding portion and the rotary shaft, wherein The rotating shaft and the winding portion have a slit into which the switching position in the winding direction of the electric wire is inserted, and the electric wire on the movable body side which is one side pulled out from the slit and the other side pulled out from the slit. a movable member for feeding structure in which the fixing portion of the wire is characterized by different winding directions der Rukoto each other is.

According to the present invention, when the movable body moves in a direction away from the surplus length absorbing mechanism, the rotating body rotates against the urging force of the urging means, and the movable body wound around the winding section is moved. When the electric wire on the body side is pulled out and the movable body moves in a direction approaching the surplus length absorbing mechanism, the rotating body is rotated by the urging force of the urging means, and the electric wire on the movable body side is the winding portion. The extra length is absorbed.

Then, for example, if the extra length absorbing mechanism is attached to the fixed portion side, it is not necessary to attach any component to the movable body side, and therefore the attachment is easy. The extra length absorbing mechanism is provided with a rotating body for winding the electric wire, an urging means for urging the rotating body, and a twist preventing wire accommodating portion for winding the electric wire in a direction opposite to the winding direction of the rotating body. Since both of them are arranged around the center of rotation, the structure is simple. As described above, it is possible to provide a power feeding structure for a movable body which is easy to install and can be configured compactly.

Each of the divided case bodies 72, 73 is provided with a pair of rotation support portions 72a, 73a for rotatably supporting the rotating body 80. As shown in FIG. 9A, the case 71 is divided into a surplus length electric wire accommodating portion 74, a twist preventing electric wire accommodating portion 75, and a spring accommodating portion 76 in the axial direction of the rotating shaft 81 described below. The case 71 has almost the same outer diameter dimensions at the extra length electric wire accommodation portion 74, the twist prevention electric wire accommodation portion 75, and the spring accommodation portion 76.

The extra length electric wire housing portion 74 is provided with a first electric wire port 74a through which the flat electric wire W side connected to the sunroof 30 is drawn out. The twisting-prevention electric wire housing portion 75 is provided with a second electric wire port 75a through which the flat electric wire W side connected to the fixed portion side (vehicle body 1 side) is drawn out. The first electric wire port 74a and the second electric wire port 75a are arranged at positions shifted with respect to the axial direction of the rotating shaft 81 described below.

The rotating body 80 is formed of an integral member. The rotating body 80 has a rotating shaft 81 supported by a pair of rotating support parts 72 a and 73 a, and a winding part 82 integrally provided on the rotating shaft 81. The winding section 82 is arranged in the extra length electric wire accommodation section 74. The winding portion 82 has a circumferential winding surface 82b surrounded by a pair of side walls 82a. Both ends of the rotary shaft 81 project to both sides of the winding portion 82, and the projecting portions on both sides of the rotary shaft 81 are arranged so as to penetrate the twist-prevention wire housing portion 75 and the spring housing portion 76. A slit 83 is formed in the rotating body 80 so as to extend over the winding portion 82 and the rotating shaft 81.

The slits 83 are open to the winding surface 82b of the winding portion 82, the outer peripheral surface of the rotating shaft 81 arranged in the twisting prevention electric wire housing portion 75, and the outer peripheral surface of the portion penetrating the spring housing portion 76. In the slit 83, a switching position in the winding direction of the flat electric wire W is inserted. The flat electric wire W connected to the movable body (sunroof 30) side which is one side is inserted into the slit 83 from the opening of the winding surface 82b. The electric wire on the side of the movable body (sunroof 30), which is the one side, is drawn out of the case from the first electric wire port 74a in a state in which it can be wound around the winding portion 82.

The flat electric wire W inserted in the slit 83 is drawn out from the opening of the slit 83 of the rotary shaft 81. The drawn-out flat electric wire W is wound in the twisting prevention electric wire housing portion 75 in a direction opposite to the winding direction of the winding portion 82 (the winding direction of the flat electric wire W on the movable body (sunroof 30) side). The tip side is drawn out of the case from the second electric wire port 75a. The length of the spiral-shaped electric wire in the twisting-prevention electric wire accommodation portion 75 is set to a length at which at least the extra length absorption dimension of the flat electric wire W can be absorbed by changing the spiral shape (a spiral with a loose winding and a spiral with a tight winding). It is set.

The spring guide member 84 is arranged in the spring accommodating portion 76. The spring guide member 84 is formed of two divided bodies 84a and 84b assembled together. The spring guide member 84 is fixed to the case 71.

The spiral spring 90 is arranged in the spring accommodating portion 76 while its spring shape is regulated by the spring guide member 84. The spiral spring 90 has its outer peripheral end 90a (shown in FIG. 8) inserted and locked in the slit 84c of the spring guide member 84, and its inner peripheral end 90b (shown in FIG. 8) inserted in the slit 83 of the rotary shaft 81. It has been suspended. The spiral spring 90 urges the rotating body 80 and thus the winding portion 82 in a direction in which the flat electric wire W on the movable body (sunroof 30) side is wound.

In the above-mentioned configuration, when the actuator 49 is driven, the pair of drive belts 40 are moved so as to be at the same position in the vehicle front-rear direction FR on one end side thereof, and the sunroof 30 is moved to the positions of three patterns as shown in FIG. You can

In the process of moving the sunroof 30 in the sliding direction, when the sunroof 30 is moved to increase the excess length of the flat electric wire W (for example, from the closed position of the sunroof 30 in FIG. 3A to the open position in FIG. 3C). (When moving), the rotating body 80 is rotated by the spring force of the spiral spring 90, and the extra length portion of the flat electric wire W is wound around the winding portion 82 (see FIG. 10B). During the movement of the sunroof 30 in the sliding direction, when the sunroof 30 is moved to reduce the excess length of the flat electric wire W (for example, from the open position of the sunroof 30 of FIG. 3C to the closed position of FIG. 3A). (When moving), the rotating body 80 rotates against the spring force of the spiral spring 90, and the extra length portion of the flat electric wire W is pulled out from the winding portion 82 (see FIG. 10A). As a result, it is possible to reliably absorb the extra length of the flat electric wire W while maintaining the linear routing state in the portion other than the extra length of the flat electric wire W.

In the surplus length absorbing mechanism 70 during the sliding movement of the sunroof 30, the twisting prevention wire accommodating portion 75 is rotated by the rotation of the rotating body 80 in the direction in which the flat electric wire W on the movable body (sunroof 30) side is wound. The flat electric wire W changes its winding form in a direction in which the number of windings is reduced (see FIG. 10B). When the rotating body 80 rotates in the direction in which the flat electric wire W on the movable body (sunroof 30) side is pulled out, the flat electric wire W of the twist-prevention electric wire accommodating portion 75 changes its winding form in a direction in which the number of windings is increased (FIG. 10(a)). In this way, the flat electric wire W of the twisting prevention wire accommodating portion 75 only changes its winding form, and twisting (rotation) does not occur at the portion of the flat electric wire W pulled out from the twisting prevention electric wire accommodating portion 75.

In this way, when the sunroof 30 has three patterns, the power source on the vehicle body 1 side always supplies power to the sunroof 30 through the flat electric wire W.

As described above, in the movable body power supply structure that supplies power from the side of the vehicle body 1 that is the fixed portion to the sunroof 30 that is the movable body, the extra length absorption mechanism 70 that absorbs the extra length of the flat electric wire W is provided. The long absorption mechanism 70 includes a rotating body 80 having a winding section 82 for winding the flat electric wire W on the movable body (sunroof 30) side from a switching position in the winding direction in the middle of the flat electric wire W, and the rotating body 80 being a movable body ( What is the spiral spring 90 that urges the flat electric wire W on the sunroof 30 side in the winding direction and the flat electric wire W on the fixed portion (vehicle body 1) side from the switching position as the winding direction of the flat electric wire W on the winding portion 82? And a twist-prevention electric wire accommodating portion 75 for accommodating the wound portion in the opposite winding direction. With such a configuration, and, for example, if the extra length absorbing mechanism 70 is attached to the fixed portion (vehicle body 1) side, it is not necessary to attach any components to the movable body (sunroof 30) side, and therefore the attachment is easy. is there. In the extra length absorbing mechanism 70, the rotating body 80 that winds the flat wire W, the spiral spring 90 that is a biasing unit that biases the rotating body 80, and the flat wire W that is opposite to the winding direction of the rotating body 80. A twist-prevention electric wire housing portion 75 for winding is provided, and since all of these are arranged with the center of rotation as the center, they can be made compact.

The extra length absorbing mechanism 70 has a simple structure because only the rotating body 80 and the spiral spring 90 for urging the rotating body 80 are arranged. As described 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 rotating body 80 has a rotating shaft 81 and a winding portion 82, and the switching portion in the winding direction of the flat electric wire W is inserted into a slit 83 formed in the rotating shaft 81 and the winding portion 82 and pulled out from the slit 83. The flat electric wire W on the movable body (sunroof 30) side that is one side of the flat wire W on the fixed portion (vehicle body 1) side that is the other side that is drawn out from the slit 83 have different winding directions. Therefore, when the sunroof 30 is slidingly moved, the flat electric wire W of the twisting prevention electric wire housing portion 75 only changes its winding form, and the flat electric wire W drawn out from the twisting prevention electric wire housing portion 75 is not No twist (rotation) occurs. It is possible to prevent damage to the flat electric wire W due to twisting, defective conduction, and the like, and maintain the durability and connection reliability of the flat electric wire W.
