[0005] Patent Document 1: Japanese Patent Application Publication No. 2021-19386 Summary of the invention

[0006] Technical problem that the invention aims to solve

[0007] However, for example, in a conventional power supply device for a sliding door, when the fixing position of the wiring harness on the sliding door side is set at a position above the vehicle relative to the guard plate on the side beam, the bridging portion is exposed in the vehicle cabin when the sliding door is in the fully closed position. Therefore, in the conventional power supply device for a sliding door, the bridging portion can be visually confirmed from the vehicle cabin when the sliding door is in the fully closed position, so it is not preferred in terms of aesthetics. Moreover, in the conventional power supply device for a sliding door, since the bridging portion is located at a position that can be touched by the occupants in the vehicle cabin, it is not preferred from the viewpoint of the durability of the wiring harness. In addition, in another conventional power supply device for a sliding door, the bridging portion is introduced into the inner side of the door trim of the sliding door so that the end of the end thereof is retained by a single-axis rotating mechanism. Moreover, in the power supply device for a sliding door, by operating the rotating mechanism when the sliding door is opened and closed, the bridging portion is caused to follow the movement on the inner side of the door trim, so that the lower end of the door trim can be lowered toward the lower side of the vehicle. However, in the conventional power supply device for sliding doors, the distance between the lower end of the door trim and the guard plate can be narrowed, which is preferred in terms of aesthetics. On the other hand, the range of motion of the rotating mechanism on the inner side of the door trim is large, and the space occupied by the rotating mechanism on the inner side of the door trim increases, thereby reducing the mounting capacity of door installation components (electrical components such as speakers, beverage holders, etc.) installed on the sliding door.

[0008] Therefore, an object of the present invention is to provide a power supply device for a sliding door that improves the appearance when viewed from within a vehicle cabin and the mountability of door installation components.

[0009] Technical solutions to the problem

[0010] The present invention is characterized in that it comprises: a wiring harness having a bridging portion spanned between a vehicle body and a sliding door, wherein the bridging portion is introduced into the inner side of the door trim through a position closer to the lower side of the vehicle than the lower end of the door trim; a vehicle body side protector, wherein the vehicle body side protector is fixed to the vehicle body, and the vehicle body side end portion of the bridging portion is inserted through and the bridging portion is led out toward the sliding door side; and a vehicle door side protector, wherein the bridging portion introduced into the inner side of the door trim is arranged toward an introduction portion located in a closing action direction of the sliding door when the sliding door is fully closed, and the vehicle door side end portion of the bridging portion introduced into the introduction portion is arranged toward the upper side of the vehicle. The invention relates to a rotating component, wherein the rotating component comprises: a bearing portion, which uses the cylinder axis of the cylinder as the axis of a first rotating axis, and utilizes the force received by the door side protector from the door side end of the bridge portion as the sliding door is opened and closed to rotate the door side protector around the axis of the cylinder portion; and a rotating shaft portion, which uses the vehicle width direction as the axis of a second rotating axis; and a fixed component, which is fixed to the inner panel of the sliding door and has a bearing portion, and the bearing portion utilizes the force received by the rotating component from the door side end of the bridge portion via the door side protector to rotate the rotating component around the rotating shaft portion.

[0011] Effects of the Invention

[0012] The power supply device for sliding door involved in the present invention enables the movement of the bridging portion when opening and closing the sliding door to follow the movement of the two-axis rotation mechanism (door side protector, rotating component, fixed component) realized by the first rotating shaft and the second rotating shaft. Therefore, the power supply device for sliding door involved in the present invention can suppress the exposure of the bridging portion when opening and closing the sliding door to a minimum, thereby improving the aesthetics when viewed from the interior of the vehicle. Moreover, the power supply device for sliding door involved in the present invention is provided with a two-axis rotation mechanism with a smaller range of motion than the conventional single-axis rotation mechanism. Therefore, compared with the conventional power supply device for sliding door, the space occupied by the two-axis rotation mechanism on the inner side of the door trim can be reduced, and the mounting properties of the door installation components (electrical components such as speakers, beverage holders, etc.) can be improved.

[0044] Hereinafter, an embodiment of the power supply device for sliding door according to the present invention will be described in detail based on the drawings. However, the present invention is not limited to this embodiment.

[0045] [Implementation Method]

[0046] based on Figures 1 to 7 One embodiment of the power supply device for a sliding door according to the present invention will be described.

[0047] Figure 1 and Figure 2 Reference numeral 1 denotes a power supply device for a sliding door according to the present embodiment.

[0048] The power supply device 1 for a sliding door is mounted on a vehicle such as a car provided with a sliding door 500 that can reciprocate in a sliding direction relative to a vehicle body B. Figure 1 and Figure 2 ). The sliding door 500 is, for example, disposed on the side of the vehicle and reciprocates in the front-rear direction of the vehicle. The power supply device 1 for the sliding door is, for example, responsible for supplying power from a power source (secondary battery, etc.) on the vehicle body B side to an electrically connected object (not shown) on the sliding door 500 side. The electrically connected object is a component such as an electrical component, a switch, etc. disposed on the sliding door 500. For example, the electrical component of the sliding door 500 represents a drive device for driving an electric window, a speaker, etc. Moreover, the switch of the sliding door 500 represents a switch for operating an electric window, a switch for operating an electric chair, etc.

[0049] The power supply device 1 for a sliding door includes a wiring harness 10 ( Figure 1 and Figure 2 ). The wire harness 10 has one end portion electrically connected to a power source directly or indirectly on the vehicle body B side, and has the other end portion electrically connected to an electrically connected object directly or indirectly on the sliding door 500 side. Therefore, the wire harness 10 has a bridging portion 11, which is a portion existing between the one end portion and the other end portion and spans between the vehicle body B and the sliding door 500 ( Figure 1 and Figure 2That is, in the wire harness 10, one end portion exists at the end of one end of the bridging portion 11, and the other end portion exists at the end of the other end of the bridging portion 11. In addition, in the bridging portion 11, although not shown, an exterior component such as a corrugated tube is provided on the outside thereof.

[0050] In the wire harness 10, one end of the bridging portion 11 (hereinafter referred to as the "vehicle body side end") is assembled to the vehicle body B side ( Figure 1 and Figure 2 The power supply device 1 for sliding door includes a protector (hereinafter referred to as a "body side protector") 20, which is fixed to the body B and allows the body side end of the bridge portion 11 to be inserted and the bridge portion 11 to be led out to the sliding door 500 side ( Figure 1 and Figure 2 The vehicle body side end portion of the bridge portion 11 is assembled to the vehicle body B via the vehicle body side protector 20. The vehicle body side protector 20 is formed of an insulating material such as synthetic resin.

[0051] The vehicle body side protector 20 is fixed to the vehicle body B by screwing, for example, and is assembled so as not to be displaced relative to the vehicle body B. The vehicle body side protector 20 shown here is provided at a position closer to the vehicle lower side than the upper wall B1a of the side beam B1 of the vehicle body B ( Figure 1 and Figure 2 ). In addition, the side beam B1 in the figure shows only a part thereof.

[0052] The vehicle body side protector 20 has an opening opened toward the sliding door 500 in the vehicle width direction, and the bridging portion 11 is led out from the opening toward the sliding door 500 ( Figure 1 The bridge portion 11 extending from the vehicle body side protector 20 is extended to the sliding door 500 side via the side wall B1b of the side beam B1 ( Figure 1 and Figure 2 ). For example, a notch or a through hole through which the bridge portion 11 passes is formed in the side wall B1b of the side beam B1.

[0053] In the wire harness 10, the other end of the bridge portion 11 (hereinafter referred to as the "door side end") is assembled to the sliding door 500 side ( Figure 1 and Figure 2 In the wiring harness 10, the bridge portion 11 is introduced between the inner panel 501 of the sliding door 500 and the door trim 502 (i.e., the inner side of the door trim 502), and the door side end portion is assembled to the inner panel 501 side. The bridge portion 11 is introduced to the inner side of the door trim 502 at a position closer to the lower side of the vehicle than the lower end 502a of the door trim 502 ( Figure 1 and Figure 2The power supply device 1 for sliding door includes a protector (hereinafter referred to as a "door side protector") 30, which is a component that allows the bridging portion 11 introduced into the inner side of the door trim 502 to be arranged toward the introduction portion 31 located in the closing direction of the sliding door 500 (here, the front of the vehicle) when the sliding door 500 is fully closed, so that the door side end of the bridging portion 11 introduced into the introduction portion 31 is directed toward the upper side of the vehicle and is led out from the cylindrical portion 32 ( Figures 1 to 3 ). The door side protector 30 is formed of an insulating material such as synthetic resin. In addition, the inner panel 501 and the door trim 502 in the figure only show a part thereof.

[0054] The door side protector 30 is formed as a cylindrical protector member ( Figure 3 ). The door side protector 30 shown here makes the cylinder axes of the introduction part 31 and the cylinder part 32 intersect at an obtuse angle. When the door is fully closed, the door side protector 30 is arranged so that the opening 30a at one end (the opening of the introduction part 31) faces the opening direction of the sliding door 500 (here, the rear of the vehicle), and the opening 30b at the other end (the opening of the cylinder part 32) faces the upper part of the vehicle ( Figures 1 to 3 ). Moreover, when the door is fully closed, the door side protector 30 is arranged at intervals in the closing direction of the sliding door 500 (the front of the vehicle) from the position where the bridge portion 11 is pulled into the inner side of the door trim 502 ( Figure 1 and Figure 2 Therefore, after the bridging portion 11 is introduced into the inner side of the door trim 502 when the door is fully closed, it is arranged toward the closing direction of the sliding door 500 (the front of the vehicle). Figure 1 and Figure 2 The door-side end of the bridge portion 11 is introduced into the introduction portion 31 from the opening 30a of the introduction portion 31 toward the closing direction of the sliding door 500 (the front of the vehicle) when the door is fully closed, and is led out from the opening 30b of the cylindrical portion 32 toward the top of the vehicle through the introduction portion 31 and the cylindrical portion 32. The bridge portion 11 shown here is introduced into the inner side of the door trim 502 through a position closer to the lower side of the vehicle than the corner portion 502b of the lower end 502a of the door trim 502 located in the opening direction of the sliding door 500 (the rear of the vehicle) when the door is fully closed ( Figure 1 and Figure 2 ). Therefore, the bridging portion 11 shown here when the door is fully closed is arranged from the introduced position toward the closing action direction of the sliding door 500 (the front of the vehicle), and is introduced into the introduction portion 31 at its end.

[0055] The power supply device 1 for sliding door rotates the door side protector 30 together with the door side end of the bridge portion 11 through two rotating shafts with different axial directions when the sliding door 500 is opened or closed. Therefore, the power supply device 1 for sliding door includes a rotating member 40, which includes: a bearing portion 41, which uses the cylinder axis of the cylinder portion 32 as the axis of the first rotating shaft R1, and uses the force received by the door side protector 30 from the door side end of the bridge portion 11 as the sliding door 500 is opened or closed to rotate the door side protector 30 around the cylinder portion 32; and a rotating shaft portion 42, which uses the axis of the second rotating shaft R2 ( Figures 1 to 3 ). In addition, the sliding door power supply device 1 includes a fixing member 50, which is fixed to the inner panel 501 of the sliding door 500 and has a bearing portion 51, which uses the force received by the rotating member 40 from the door side end of the bridging portion 11 via the door side protector 30 to rotate the rotating member 40 around the rotating shaft portion 42 ( Figures 1 to 3 ). The rotating member 40 and the fixing member 50 are formed of insulating materials such as synthetic resin.

[0056] In the rotating member 40, the bearing portion 41 is formed into a ring shape that concentrically surrounds the outer peripheral surface of the cylindrical portion 32, so that the cylindrical portion 32 disposed inside the bearing portion 41 can rotate concentrically around the first rotation axis R1. The bearing portion 41 is clamped by the curved portion (the boundary portion between the introduction portion 31 and the cylindrical portion 32) of the door side protector 30 and the annular flange 32a provided on the opening 30b side of the outer peripheral surface of the cylindrical portion 32, thereby holding the cylindrical portion 32 to be freely rotatable concentrically ( Figure 3 ).

[0057] In addition, in the rotating member 40, a circular ring-shaped or cylindrical rotating shaft portion 42 ( Figure 3 ). In the rotating member 40 shown here, a rotating shaft portion 42 is arranged on the closing operation direction side of the sliding door 500 (vehicle front) relative to the bearing portion 41.

[0058] The fixing member 50 is provided with a bearing portion 51 and has a fixing portion 52 ( Figures 1 to 3 ). The fixing portion 52 is fixed to the inner panel 501 by screwing, for example, and is assembled so as not to be relatively displaced relative to the inner panel 501. The fixing portion 52 shown here is formed in a plate shape, and a portion thereof has a bearing portion 51 formed in a circular ring shape or a cylindrical shape. The bearing portion 51 is embedded in the axial direction relative to the rotating shaft portion 42, and the rotating shaft portion 42 is held to be freely rotatable on the same axis.

[0059] In addition, the fixing member 50 has a protector portion 53 that surrounds the door-side end portion ( Figures 1 to 3The protector portion 53 is formed into a cylindrical shape, guides the door-side end portion of the bridging portion 11 drawn from the cylindrical portion 32 toward the upper side of the vehicle toward the closing direction of the sliding door 500 (the front of the vehicle), and draws it out from the opening toward the closing direction (the front of the vehicle).

[0060] The door side end portion of the bridge portion 11 is assembled to the vehicle body B via a biaxial rotation mechanism composed of the door side protector 30, the rotation member 40, and the fixing member 50. The bridge portion 11 changes its shape between the vehicle body side protector 20 and the door side protector 30 by opening and closing the sliding door 500, so that a reaction force generated by the shape change acts on the vehicle body side protector 20 from the vehicle body side end portion and acts on the door side protector 30 from the door side end portion.

[0061] The vehicle body side protector 20 is fixed to the vehicle body B, and therefore the force received from the vehicle body side end of the bridge portion 11 is directly returned to the vehicle body side end as a reaction force. On the other hand, when the door side protector 30 receives a force from the door side end of the bridge portion 11, it rotates relative to the fixing member 50 around the first rotation axis R1 (around the cylindrical portion 32) with a rotation torque corresponding to the force component of the force, and rotates relative to the fixing member 50 around the second rotation axis R2 (around the rotation shaft portion 42) with a rotation torque corresponding to the force component of the force.

[0062] In the sliding door power supply device 1, when the sliding door 500 in the fully closed position is opened, the door side protector 30 receives force from the door side end of the bridge portion 11, so that the opening 30a of the introduction portion 31 facing the opening action direction of the sliding door 500 (the rear of the vehicle) when the door is fully closed faces the inner side of the vehicle interior, and the door side protector 30 and the door side end of the bridge portion 11 rotate forward around the first rotation axis R1 ( Figure 1 , Figure 2 , Figure 4 as well as Figure 5 ). In addition, in the sliding door power supply device 1, when the sliding door 500 in the fully closed position is opened, the rotating member 40 receives a force from the door side end of the bridging portion 11 via the door side protector 30, so that the opening 30a of the introduction portion 31 facing the opening action direction of the sliding door 500 (the rear of the vehicle) when the door is fully closed is directed toward the lower side of the vehicle, and the door side protector 30, the door side end of the bridging portion 11, and the rotating member 40 are rotated about the second rotation axis R2 ( Figure 1 , Figure 2 , Figure 4 as well as Figure 5 ).

[0063] The jumper 11 shown here has a wiring path when the door is fully closed. Figure 1 and Figure 2 ) of the sliding door 500 reaches the half-open position ( Figure 6 ), the force acting on the door side protector 30 from the door side end is small. Therefore, in the sliding door power supply device 1 shown here, until the sliding door 500 in the fully closed position reaches the half-open position, the rotation angle of the door side protector 30 around the first rotation axis R1 and the rotation angle around the second rotation axis R2 are respectively reduced ( Figure 7 In addition, the bridge portion 11 shown here is a wiring path when the door is fully closed, and the sliding door 500 in the half-open position is moved to the fully open position ( Figure 5 ) moves, it descends toward the lower part of the vehicle between the vehicle body side protector 20 and the vehicle door side protector 30, so a large force acts on the vehicle door side protector 30 from the vehicle door side end toward the lower part of the vehicle. Therefore, in the sliding door power supply device 1 shown here, when the sliding door 500 in the half-open position moves to the fully-open position, the rotation angle of the door side protector 30 around the first rotation axis R1 and the rotation angle around the second rotation axis R2 are respectively larger than when the sliding door 500 in the fully-closed position moves to the half-open position ( Figure 4 , Figure 5 as well as Figure 7 ).

[0064] In the sliding door power supply device 1, when the sliding door 500 in the half-open position is moved to the fully-open position, the door side protector 30 and the door side end portion of the bridging portion 11 are rotated forward about the first rotation axis R1 so that the opening 30a of the introduction portion 31 in the opening operation direction (the rear of the vehicle) of the sliding door 500 from the fully-closed position to the half-open position is directed toward the vehicle interior ( Figure 4 , Figure 5 as well as Figure 7 ). In addition, in the sliding door power supply device 1, when the sliding door 500 in the half-open position is moved to the fully-open position, the door side protector 30, the door side end of the bridging portion 11, and the rotating member 40 are rotated forward about the second rotation axis R2 in such a manner that the opening 30a of the introduction portion 31 in the opening direction (the rear of the vehicle) of the sliding door 500 from the fully-closed position to the half-open position is directed toward the lower side of the vehicle ( Figure 4 , Figure 5 as well as Figure 7 That is, in the sliding door power supply device 1, when the sliding door 500 in the half-open position is moved to the fully-open position, the door side protector 30 and the door side end of the bridge portion 11 are rotated forward around the first rotation axis R1, and the door side protector 30, the door side end of the bridge portion 11 and the rotating member 40 are rotated forward around the second rotation axis R2 in such a manner that the opening 30a of the introduction portion 31 in the opening action direction of the sliding door 500 from the fully-closed position to the half-open position (the rear of the vehicle) is directed toward the inner side of the vehicle compartment and the lower side of the vehicle.

[0065] The bridge portion 11 moves from the corner portion 502b to the closing direction (vehicle front) of the sliding door 500 at a position passing through the lower side of the vehicle than the lower end 502a of the door trim 502 as the sliding door 500 at the fully closed position opens. In other words, the sliding door 500 at the fully closed position opens toward the fully opened position while the lower end 502a of the door trim 502 is along the bridge portion 11. Therefore, in the sliding door power supply device 1 of the present embodiment, when the sliding door 500 at the fully closed position is opened toward the fully opened position, the bridge portion 11 is still introduced into the inner side of the door trim 502 through the position at the lower side of the vehicle than the lower end 502a of the door trim 502. Therefore, the sliding door power supply device 1 can minimize the exposure of the bridge portion 11 when the sliding door 500 at the fully closed position is opened toward the fully opened position, thereby improving the aesthetics when viewed from the interior of the vehicle.

[0066] On the other hand, the jumper 11 shown here has a wiring path when the door is fully closed, and in the fully open position ( Figure 5 ) of the sliding door 500 to a half-open position ( Figure 6 ) moves, it returns to the upper part of the vehicle between the body side protector 20 and the door side protector 30, so a large force acts on the door side protector 30 from the door side end toward the upper part of the vehicle. Therefore, in the sliding door power supply device 1 shown here, when the sliding door 500 in the fully open position moves to the half-open position, the rotation angle of the door side protector 30 around the first rotation axis R1 and the rotation angle around the second rotation axis R2 are respectively larger than when the sliding door 500 in the half-open position moves to the fully closed position. In addition, the jumper 11 shown here is arranged to be connected to the fully closed position ( Figure 1 and Figure 2 ), the force acting on the door side protector 30 from the door side end is small. Therefore, in the sliding door power supply device 1 shown here, before the sliding door 500 in the half-open position reaches the fully closed position, the rotation angle of the door side protector 30 around the first rotation axis R1 and the rotation angle around the second rotation axis R2 are respectively smaller than when the sliding door 500 in the fully open position moves to the half-open position.

[0067] In the sliding door power supply device 1, when the sliding door 500 in the fully open position is moved to the half-open position, the door side protector 30 and the door side end portion of the bridging portion 11 are reversed about the first rotation axis R1 in such a manner that the opening 30a of the introduction portion 31 facing the inner side of the vehicle compartment in the fully open position faces the opening operation direction of the sliding door 500 (the rear of the vehicle). Figure 4 , Figure 5 as well as Figure 7). In addition, in the sliding door power supply device 1, when the sliding door 500 in the fully open position is moved to the half-open position, the door side protector 30, the door side end of the bridging portion 11, and the rotating member 40 are reversed around the second rotation axis R2 in such a manner that the opening 30a of the introduction portion 31 facing the lower side of the vehicle in the fully open position faces the opening direction of the sliding door 500 (the rear of the vehicle) ( Figure 4 , Figure 5 as well as Figure 7 That is, in the sliding door power supply device 1, the door side protector 30 and the door side end of the bridge portion 11 are reversed around the first rotation axis R1, and the door side protector 30, the door side end of the bridge portion 11, and the rotating member 40 are reversed around the second rotation axis R2 in such a manner that the opening 30a of the introduction portion 31, which is located inside the vehicle compartment and toward the lower side of the vehicle, is oriented toward the opening direction of the sliding door 500 (the rear of the vehicle) when in the fully open position.

[0068] The bridge portion 11 moves from a position passing through the lower side of the vehicle than the lower end 502a of the door trim 502 toward the corner portion 502b located in the opening direction (the rear of the vehicle) of the sliding door 500 as the sliding door 500 in the fully open position closes. In other words, the sliding door 500 in the fully open position closes toward the fully closed position with the lower end 502a of the door trim 502 along the bridge portion 11. Therefore, in the sliding door power supply device 1 of the present embodiment, when the sliding door 500 in the fully open position is closed toward the fully closed position, the bridge portion 11 is still introduced into the inner side of the door trim 502 through the position passing through the lower side of the vehicle than the lower end 502a of the door trim 502. Therefore, the sliding door power supply device 1 can minimize the exposure of the bridge portion 11 when the sliding door 500 in the fully open position is closed toward the fully closed position, thereby improving the aesthetics viewed from the interior of the vehicle.

[0069] As shown above, the power supply device 1 for sliding door of the present embodiment makes the movement of the bridging portion 11 when opening and closing the sliding door 500 follow the movement of the two-axis rotating mechanism (door side protector 30, rotating component 40, fixed component 50) based on the first rotating axis R1 and the second rotating axis R2. As a result, the power supply device 1 for sliding door of the present embodiment can minimize the exposure of the bridging portion 11 when opening and closing the sliding door 500, thereby improving the aesthetics when viewed from the interior of the vehicle. In addition, the power supply device 1 for sliding door of the present embodiment is provided with a two-axis rotating mechanism having a smaller range of motion than the conventional single-axis rotating mechanism, so that the space occupied by the two-axis rotating mechanism on the inner side of the door trim 502 can be reduced compared to the conventional situation, and the mounting performance of the door installation components (electrical components such as speakers, beverage holders, etc.) can be improved.
