Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a power supply structure for supplying power to a door glass raising / lowering motor of a sliding door for a vehicle.

[0002]

2. Description of the Related Art In recent years, as the use of van-type vehicles as RVs has expanded, in order to automate the raising and lowering of the door glass, power is supplied from the vehicle body side to a door glass raising / lowering motor and a limit switch provided on a sliding door. Need to be done. Therefore, a power supply structure as shown in FIGS. 5 and 6 has been proposed (for example, Japanese Patent Application Laid-Open No. H11-348683). Here, FIG. 5 is a lower vertical sectional view of the sliding door D for a vehicle in an open state, and FIG. 6 is a horizontal sectional view thereof. The inner panel of the sliding door D is provided with an L-shaped (FIG. 5) stay 1 projecting toward the body panel P.
A roller bracket 12 is attached to an end of the roller via an auxiliary plate 11. The roller bracket 12 is coupled to the auxiliary plate 11 so as to be rotatable in a horizontal plane. Horizontal rollers 13 and 14 are provided at the ends of the legs 121 and 122 (FIG. 6) which are separated into two in plan view. The horizontal rollers 13 and 14 are located in a lower guide rail 21 provided on the lower surface of the step panel 2 (FIG. 5). The central portion of the roller bracket 12 is bent downward, and the vertical roller 15 is supported on the central portion, and is located on the body panel P. When the slide door D is closed, it is guided by the guide rail 21, moves forward of the vehicle (to the right in FIG. 6), and is then drawn inward of the vehicle (downward in FIG. 6).

A guide rail 3 is provided on the inner panel of the slide door D in the door opening and closing direction. The guide rail 3 has a U-shaped cross section that opens downward (FIG. 5), and a slider 4 is provided at its opening so as to be movable along the guide rail 3.
Is provided. A flat cable 41 extends from the front end of the slider 4 (the side facing the plane of FIG. 5), and this flat cable 41 is folded upward in a U-shape, reaches the rear end along the top wall of the guide rail 3, and The input is connected to the front end of the relay connector 42 provided here. A power supply line (not shown) extends from the rear end of the relay connector 42 to a door glass elevating motor or the like in the slide door. A support member 7 is provided between the slider 4 and the step panel 2. The support member 7 has metal terminals 72 and 73 having circular ring portions 721 and 731 fixed to both ends of a flexible metal wire 71 that can be bent and deformed. The circular ring portion 721 of the metal terminal 72 is The circular ring portion 731 of the metal terminal 73 is rotatably fitted to the bolt 22 provided on the step panel 2 while being rotatably fitted to a bolt 61 provided on the slider 4. The power supply line 54 extending from the slider 4 to the vehicle body side is connected to the metal wire 7.
1, is inserted into the tube 74, passes over the vehicle body side, curves upward, penetrates the step panel 2, and is connected to a wire harness (not shown).

In such a structure, the sliding door D
When the guide rail 3 moves forward from the open state to the closing direction of the vehicle, the slider 4 is pulled by the support member 7 even if the guide rail 3 moves forward (to the right in FIG. 6), and the movement of that position is restricted. As a result, the slider 4 moves relative to the guide rail 3. When the slide door D reaches the front end and is pulled toward the closed position inside the vehicle, the support member 7 turns around the bolt 22 in the clockwise direction in FIG. In this case, the turning locus of the support member 7 and the moving locus of the slide door D do not always match, but the relative displacement between the two is absorbed by the metal wire 71 of the support member 7 being appropriately curved and deformed.

[0005]

By the way, in the above-described conventional power supply structure, when the support member 7 rotates forward and backward around the bolt 61 with the opening and closing of the slide door D, the power supply line 5
4 may be bent with a large curvature particularly at the portion A in FIG. 5, and in this case, the power supply line 54 may be disconnected.
Further, in the above-described power supply structure, there is a problem that the metal terminal 72 and the mounting structure thereof are relatively complicated.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve such a problem, and an object of the present invention is to provide a power supply structure of a sliding door for a vehicle which can prevent a power supply line from being disconnected or the like with a simple structure.

[0007]

In order to achieve the above object, according to the present invention, a rail member (3) provided on a slide door (D) and extending in the door opening and closing direction is provided relative to the rail member (3). A slider (8) movably provided;
A power supply line (54) extending from the vehicle body side to the electric parts in the slide door (D) via the slider (8); A guide hole (84) through which the electric wire (54) is inserted is formed, and both openings (8) of the guide hole (84) are formed.
41, 842) from the vehicle body side (5
4) The opening inner wall surface (84) of the opening (842) located on the side where the wire enters is located in the sliding direction of the slider (8).
3,844) is formed so as to be curved in the sliding direction with a radius of curvature equal to or greater than a predetermined radius of curvature so that the opening (842) expands in the opening direction.

In the present invention, a guide hole having an opening inner wall surface which is curved in the sliding direction with a radius of curvature equal to or larger than a predetermined radius is formed in the slider so that a power supply line is inserted through the slider. The power supply line receiving tension from the body side is curved along one or other of the inner wall surfaces of the opening at the closed end or the open end of the door.
As a result, the curvature of the power supply line does not become excessively large, thereby preventing the power supply line from being disconnected or the like.
In the present invention, by providing a guide portion on the slider,
Disconnection of the power supply line can be prevented with a simple structure without using a conventional metal terminal.

[0009]

FIG. 1 is a longitudinal sectional view of a guide rail 3 provided on a slide door. The cross section of the guide rail 3 has a U-shape that opens downward similarly to the conventional structure, and its opening edge is a flange portion 31 that is bent inward at a substantially right angle. A slider 8 is provided at the opening of the guide rail 3 so as to be movable along the opening. FIG. 2 is a side view and FIG. 3 is an end view.

The slider 8 is formed by superposing thick plate members 81 and 82 of substantially the same shape made of Teflon (registered trademark) resin and joining them with screws 831 and 832 at two places on the plate surface to form a block body. A concave groove is formed in the abutting surface of each of the plate members 81 and 82 in a symmetrical shape with each other.
Is formed. The guide hole 84 is opened at one end surface of the slider 8 (reference numeral 841), and is gently curved downward from above in the slider 8 to open at the lower surface of the slider 8 (reference numeral 842). The width of the guide hole 84 is constant up to the vicinity of the top of the curve in a side view, and thereafter, it expands downward like a trumpet. The guide hole 84 having such a shape has a radius of curvature R1 when bending upward from the opening 841, a radius of curvature R2 when bending downward from above, and left and right inner wall surfaces 843 when the opening 842 portion spreads downward. 84
The curvature radii R3 and R4 of No. 4 are all equal to or larger than a predetermined value.

In the guide hole opening 842 of the slider 8, a through hole 85 having a gradually decreasing diameter toward the top is provided with both plate members 81,
The slider 8 is formed by a concave groove and is opened to a locking recess 86 formed by cutting out the end face of the slider 8. Further, rectangular slide grooves 871, 8 of a fixed width extending in parallel along the lower side are provided at the same position on the outer surfaces of the two plate members 81, 82.
72 are formed.

The slider 8 has slide grooves 871,
As shown in FIG. 1, 872 is fitted into the opening edge flange 31 of the guide rail 3 so as to be movable. And
As in the conventional structure, the power supply line 54 that is passed through the tube 74 from the vehicle body side is inserted into the guide hole 84 of the slider 8 and is folded upward in the guide rail 3 in a U-shape. Is connected to a connector 33 provided on the lower surface of the top wall 32. The power supply line 5 into the guide hole 84
The insertion of 4 is performed by pushing the power supply line 54 into the concave groove of one of the plate members 81 in a state where the plate members 81 and 82 are separated, and abutting the other plate member 82 against this. At this time, the power supply line 54 is positioned by being sandwiched between the two plate members 81 and 82.
One end of the metal wire 71 is inserted into the through hole 85, and the metal ball 711 attached to the end engages the locking recess 86. The power supply structure on the vehicle body side is the same as the conventional one.

In such a structure, when the slide door is moved between the open state and the closed state, the movement of the slider 8 is restricted as shown in FIG. The slider 8 moves relative to the guide rail 3, and the slider 8 reaches the X position in FIGS. 1 and 4 at the door open end, and reaches the Y position at the door closed end. With the movement of the slider 8, the feeder line 54 is bent along one inner wall surface 843 in the sliding direction of the guide hole opening 842 at the X position due to the tension from the vehicle body side,
On the other hand, at the Y position, the power supply line 54 curves along the other inner wall surface 844 in the sliding direction of the guide hole opening 842.
As described above, since the radius of curvature of the curved portion other than the opening 842 and the radius of curvature of the inner wall surfaces 843 and 844 of the guide holes 84 are larger than the predetermined values, the power supply line 54 receives tension. Even if it bends, it does not bend at an excessive curvature, and disconnection of the power supply line 54 or the like is prevented.
As described above, according to the present embodiment, the guide hole 8 is formed in the slider 8 without using the metal terminal 73 as in the related art.
The wire 4 can be prevented from being broken by a simple structure in which the power supply line 54 is inserted and formed.

[0014]

As described above, according to the power supply structure for a sliding door for a vehicle of the present invention, disconnection of the power supply line can be effectively prevented with a simple structure.
