Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in this power supply device for a sliding door, the bending direction of the crossing part of the wire harness is reversed as the sliding door opens and closes. However, if the bending direction reverses abruptly, there is a possibility that the crossing part may hit surrounding parts and generate a knocking sound.

[0005] Therefore, an object of the present invention is to provide a power supply device for a sliding door that can smoothly advance the reversal of the bending direction of the crossing part.

Means for Solving the Problems

[0006] The present invention comprises a wire harness having a connecting portion that spans between the vehicle body and the sliding door; a holding member that is assembled to the vehicle body and holds one end of the connecting portion; a link mechanism that is assembled to the inner panel between the inner panel and the door trim of the sliding door, holds the other end of the connecting portion, and is linked to the displacement of the other end of the connecting portion accompanying the opening and closing operation of the sliding door; and a component provided on at least one of the inner panel and the door trim between the inner panel and the door trim, which, when the sliding door is opened from the fully closed position, spans the connecting portion The device is characterized by comprising a reversal mechanism for reversing the bending direction, wherein the connecting portion is passed between the vehicle body and the sliding door, passing below the lower end of the door trim, and the reversal mechanism comprises a guide surface that brings the connecting portion into contact with the sliding door as it opens from the fully closed position, and starts to reverse the bending direction of the connecting portion while sliding the connecting portion in conjunction with the opening operation, and a locking portion that brings the connecting portion, which has been guided by the guide surface, into contact with the connecting portion, and locks the connecting portion until the reversal of the bending direction of the connecting portion in conjunction with the opening operation of the sliding door is completed. [Effects of the Invention]

[0007] The sliding door power supply device according to the present invention, when the sliding door opens from the fully closed position, changes the position and shape of the connecting portion of the wire harness, and slides the connecting portion against the first stage guide surface of the reversal mechanism, thereby straightening the bend of the connecting portion 11. Then, the sliding door power supply device brings the connecting portion, which has been guided by the guide surface, against the second stage locking portion of the reversal mechanism, and reverses the bending direction while locking the connecting portion with the locking portion. In this way, the sliding door power supply device according to the present invention reverses the bending direction of the connecting portion in two stages, from the guide surface to the locking portion, so that the reversal of the bending direction can be carried out smoothly.

[Modes for carrying out the invention]

[0009] An embodiment of the power supply device for sliding doors according to the present invention will be described in detail below with reference to the drawings. However, this embodiment does not limit the present invention.

[0010] [Embodiment] One embodiment of the power supply device for sliding doors according to the present invention will be described with reference to Figures 1 to 9.

[0011] Reference numeral 1 in Figures 1 to 9 indicates the power supply device for the sliding door of this embodiment.

[0012] The sliding door power supply device 1 is installed in a vehicle such as an automobile that has a sliding door 500 that can reciprocate in the sliding direction relative to the vehicle body B (Figures 1 to 9). The sliding door 500 is installed, for example, on the side of the vehicle and moves back and forth in the front-rear direction of the vehicle. The sliding door power supply device 1 is responsible for supplying power from a power source (such as a secondary battery) on the vehicle body B side to the electrical connection target (not shown) on the sliding door 500 side. The electrical connection target is something installed on the sliding door 500, such as electrical components or switches. For example, the electrical components of the sliding door 500 refer to a drive unit for operating a power window, a speaker, etc. Furthermore, the switches of the sliding door 500 refer to a switch for operating a power window, a switch for operating a power seat, etc.

[0013] The power supply device 1 for the sliding door includes a wire harness 10 (Figures 1 to 9). One end of the wire harness 10 is directly or indirectly electrically connected to a power source on the vehicle body B side, and the other end is directly or indirectly electrically connected to an object to be electrically connected on the sliding door 500 side. Therefore, the wire harness 10 is a part that exists between one end and the other end, and has a connecting section 11 that spans between the vehicle body B and the sliding door 500 (Figures 1 to 9). In other words, in this wire harness 10, one end exists beyond one end of the connecting section 11, and the other end exists beyond the other end of the connecting section 11.

[0014] The connecting section 11 is assembled at one end to the vehicle body B and at the other end to the sliding door 500 between the inner panel 501 and the door trim 502 of the sliding door 500 (Figures 1 to 9). This connecting section 11 passes below the lower end of the door trim 502 and spans between the vehicle body B and the sliding door 500. The position and shape of this connecting section 11 change in conjunction with the opening and closing operation of the sliding door 500 relative to the vehicle body B. Note that in the figures, only a portion of the lower part of the inner panel 501 and door trim 502 is shown.

[0015] The power supply device 1 for the sliding door is assembled to the vehicle body B and includes a holding member 20 that holds one end of the crossing portion 11 (Figs. 1 to 9). For example, this holding member 20 includes a base member 21 and a cover member 22 that are assembled to each other (Figs. 1 to 9), and one end of the crossing portion 11 is accommodated and held in the inner wire harness path formed by the base member 21 and the cover member 22. This holding member 20 pulls the crossing portion 11 outward from the holding position of the wire harness path toward the sliding door 500 side (Figs. 1 to 9). Here, the crossing portion 11 is pulled outward toward the sliding door 500 side and in the forward direction of the vehicle. Further, this holding member 20 pulls one end side of the wire harness 10 at the tip of one end of the crossing portion 11 outward from the wire harness path.

[0016] When the sliding door 500 is in the fully closed position, the crossing portion 11 passes below the first rising portion 502a at the rear of the vehicle at the lower end of the door trim 502 at the tip pulled out from the holding member 20, passes through below the door trim 502, and is bent forward toward the vehicle at the tip that has passed through below the door trim 502, and is routed between the inner panel 501 and the door trim 502 toward the front of the vehicle (Figs. 1 to 3). In the following, the bent portion of the crossing portion 11 is referred to as the "first bent portion 11a". Then, when the sliding door 500 is in the fully closed position, the crossing portion 11 is bent upward and forward in the vehicle at the front of the vehicle, and is assembled to the sliding door 500 side at the other end of the bent tip (Figs. 1 to 3). In the following, the bent portion of the crossing portion 11 is referred to as the "second bent portion 11b".

[0017] The power supply device 1 for the sliding door is assembled to the inner panel 501 between the inner panel 501 and the door trim 502 and includes a link mechanism 30 that holds the other end of the crossing portion 11 (Figs. 1 to 9).

[0018] The link mechanism 30 includes a base member 31 fixed to the inner panel 501 via a fixing portion not shown (Figs. 1 to 9). This base member 31 has a main shaft 30a with the vehicle width direction as the axial direction (Figs. 1, 2, 4, 5, 7, and 8).

[0019] The link mechanism 30 includes a first arm member 32 having one end rotatably assembled around its axis with respect to its main shaft 30a (FIGS. 1 to 9). When the slide door 500 is in the fully closed position, the first arm member 32 extends forward from one end of the vehicle, and the end of the extended portion serves as the other end.

[0020] The link mechanism 30 includes a second arm member 33 having one end assembled to the other end of the first arm member 32 (FIGS. 1 to 9). In this link mechanism 30, the other end of the first arm member 32 and one end of the second arm member 33 are connected via a sub-shaft 30b parallel to the main shaft 30a, and the first arm member 32 and the second arm member 33 are relatively rotated around the axis of the sub-shaft 30b (FIGS. 1, 2, 4, 5, 7, and 8). When the slide door 500 is in the fully closed position, the second arm member 33 extends downward and rearward from one end of the vehicle, and the end of the extended portion serves as the other end. And this second arm member 33 holds the other end of the crossing portion 11 at its other end. When the slide door 500 is in the fully closed position, the second arm member 33 holds the other end of the crossing portion 11 bent upward and forward at the other end of the extended portion extending downward and rearward from the vehicle.

[0021] When the slide door 500 is in the fully closed position, this link mechanism 30 is arranged on the closing direction side of the slide door 500 (that is, in front of the vehicle in the vehicle longitudinal direction) than the holding member 20 in the opening and closing direction of the slide door 500 (FIGS. 1 to 3). And this link mechanism 30 is aligned with the holding member 20 in the vehicle width direction during the opening operation of the slide door 500 from the fully closed position (FIGS. 4 to 6), and when the slide door 500 is in the fully open position, it is arranged on the opening direction side of the slide door 500 (that is, behind the vehicle in the vehicle longitudinal direction) than the holding member 20 in the opening and closing direction of the slide door 500 (FIGS. 7 to 9).

[0022] This link mechanism 30 is linked to the displacement of the other end of the connecting portion 11 accompanying the opening and closing operation of the sliding door 500. Specifically, this link mechanism 30 receives force from the displaced connecting portion 11 accompanying the opening operation of the sliding door 500 from the fully closed position, and pulls the other end of the connecting portion 11 upwards towards the vehicle while rotating it in the forward direction around the axis of the main shaft 30a. Then, as the sliding door 500 opens further, it receives force from the connecting portion 11, and lowers the other end of the connecting portion 11 downwards towards the vehicle while rotating it in the reverse direction around the axis of the main shaft 30a, thereby reversing the bending direction of the connecting portion 11 (Figures 1 to 9). In the power supply device 1 for the sliding door shown here, as the sliding door 500 opens, the link mechanism 30 moves further toward the opening direction of the sliding door 500 than the holding member 20, causing the other end of the connecting portion 11, which was initially pulled upwards towards the vehicle, to descend, and reversing the bending directions of the first bent portion 11a and the second bent portion 11b of the connecting portion 11 with respect to the bending direction when the sliding door 500 is in the fully closed position.

[0023] The power supply device 1 for the sliding door includes a reversal mechanism 40 that assists in reversing the bending direction of the connecting portion 11 while the link mechanism 30 is operating and the connecting portion 11 is being displaced in conjunction with the opening operation of the sliding door 500 from the fully closed position (Figures 1 to 9). This reversal mechanism 40 is provided between the inner panel 501 and the door trim 502, on at least one of the inner panel 501 and the door trim 502, and reverses the bending direction of the connecting portion 11 when the sliding door 500 is opening from the fully closed position.

[0024] Specifically, the reversal mechanism 40 includes a guide surface 40a that contacts the connecting portion 11 as the sliding door 500 opens from the fully closed position, and starts to reverse the bending direction of the connecting portion 11 while sliding it in conjunction with the opening operation, and a locking portion 40b that contacts the connecting portion 11 that has been guided by the guide surface 40a, and locks the connecting portion 11 until the reversal of the bending direction of the connecting portion 11 in conjunction with the opening operation of the sliding door 500 is completed (Figures 1 to 9).

[0025] The guide surface 40a is formed as an inclined surface that causes the connecting portion 11 to slide diagonally in the opposite direction to the opening direction of the sliding door 500 and toward either the vehicle body B side or the sliding door 500 side (Figures 1 to 3, 5, 6, 8, and 9). As the sliding door 500 opens from the fully closed position, the other end of the connecting portion 11 is pulled upward toward the vehicle, causing the guide surface 40a to contact the portion of the second arm member 33 in the connecting portion 11 that is pulled outward from the other end. Specifically, as the sliding door 500 opens from the fully closed position, the other end of the connecting portion 11 is pulled upward toward the vehicle, causing the outer side of the bend in the second bent portion 11b of the connecting portion 11 to contact the guide surface 40a. The connecting section 11 moves relative to the guide surface 40a, being pulled upwards towards the vehicle, while displacing the sliding portion toward one end in the opposite direction to the opening direction of the sliding door 500 and toward either the vehicle body B side or the sliding door 500 side. In this connecting section 11, the bending of the first bent section 11a and the second bent section 11b is stretched out as it is pulled upwards towards the vehicle (Figures 4 to 6).

[0026] In this example, since the sliding door 500 is installed on the side of the vehicle, a guide surface 40a is formed as an inclined surface that allows the connecting section 11 to slide diagonally in the opposite direction to the opening direction of the sliding door 500 and in the direction of the vehicle width (Figures 1 to 3, 5, 6, 8 and 9).

[0027] The locking portion 40b brings into contact with the sliding portion of the connecting portion 11, which has been sliding along the guide surface 40a. Here, as the sliding door 500 opens, the holding member 20 and the link mechanism 30 are aligned in the vehicle width direction, causing the sliding portion of the connecting portion 11 to come into contact with the locking portion 40b. The connecting portion 11 is then locked to the locking portion 40b while remaining in contact with the guide surface 40a.

[0028] Incidentally, as the sliding door 500 opens further, the reversal mechanism 40 moves together with the link mechanism 30 toward the opening direction of the sliding door 500 relative to the retaining member 20 in the opening and closing direction of the sliding door 500 (i.e., toward the rear of the vehicle relative to the retaining member 20 in the vehicle longitudinal direction). As a result, the locking portion 40b continues to lock the contact portion of the connecting portion 11 while displacing it toward the other end in accordance with the downward movement of the connecting portion 11 due to the further opening of the sliding door 500, thereby reversing the bending directions of the first bent portion 11a and the second bent portion 11b of the connecting portion 11 relative to the bending direction when the sliding door 500 is in the fully closed position.

[0029] Here, the reversing mechanism 40 may have a guide surface 40a and a locking portion 40b on either the inner panel 501 or the door trim 502. In this case, the reversing mechanism 40 is composed of a single reversing member (not shown) having a guide surface 40a and a locking portion 40b, and this reversing member is assembled to either the inner panel 501 or the door trim 502.

[0030] Furthermore, the reversing mechanism 40 may be provided with a guide surface 40a on one of the inner panel 501 and the door trim 502, and a locking portion 40b on the other of the inner panel 501 and the door trim 502. In this case, the reversing mechanism 40 comprises a first reversing member 41 having a guide surface 40a and a second reversing member 42 having a locking portion 40b (Figures 1 to 9). In the reversing mechanism 40 shown here, the first reversing member 41 is assembled to the inner panel 501, and the second reversing member 42 is assembled to the door trim 502. The first reversing member 41 has an inclined guide surface 40a that causes the connecting portion 11 to slide diagonally in the opposite direction to the opening direction of the sliding door 500 and toward the vehicle body B side. The second reversing member 42 is formed as a columnar member extending in the vehicle width direction.

[0031] The sliding door power supply device 1 described above, when the sliding door 500 opens from the fully closed position, changes the position and shape of the connecting portion 11 of the wire harness 10. In this way, the connecting portion 11 is brought into contact with the first stage guide surface 40a of the reversal mechanism 40 and slid, while straightening the bends of the first bent portion 11a and the second bent portion 11b of the connecting portion 11. Then, the sliding door power supply device 1 brings the connecting portion 11, which has been guided by the guide surface 40a, into contact with the second stage locking portion 40b of the reversal mechanism 40, and while locking the connecting portion 11 with the locking portion 40b, reverses the bending direction of the first bent portion 11a and the second bent portion 11b. In this way, the sliding door power supply device 1 of this embodiment reverses the bending direction of the connecting portion 11 in two stages from the guide surface 40a to the locking portion 40b, so that the reversal of the bending direction can proceed smoothly.

[0032] For example, as the sliding door 500 moves from the fully closed position to the fully open position, the connecting portion 11 descends below the first rearward-facing portion 502a at the lower end of the door trim 502, moves below the lowest end portion 502b at the lower end of the door trim 502, and rises below the second frontward-facing portion 502c at the lower end of the door trim 502 (Figures 1 to 9). For this reason, in the power supply device 1 for the sliding door, if the connecting portion 11 is long enough to cause slack during the displacement, it becomes difficult for the connecting portion 11 to move along the lower end of the door trim 502. For example, if we assume that the locking portion 40b alone assists in reversing the bending direction of the connecting portion 11, there is a possibility that the connecting portion 11 may suddenly reverse its bending direction and hit the locking portion 40b with force. Furthermore, in this case, even if the rising shape of the second rising section 502c is steep, there is a possibility that the connecting section 11 may reverse its bending direction with a sudden movement and forcefully collide with the locking section 40b. However, in the power supply device 1 for sliding doors of this embodiment, the connecting section 11 begins to reverse its bending direction while its movement is restricted by the guide surface 40a before it hits the locking section 40b, and the connecting section 11 moves smoothly from this guide surface 40a to the locking section 40b. Therefore, even if the connecting section 11 is long enough to cause slack during displacement, and even if the rising shape of the second rising section 502c is steep, the sudden movement of the connecting section 11 when the bending direction reverses can be suppressed while the connecting section 11 moves along the lower end of the door trim 502. Accordingly, the power supply device 1 for sliding doors of this embodiment can smoothly reverse the bending direction of the connecting section 11 and suppress the generation of a knocking sound during the reversal operation. Therefore, the power supply device 1 for the sliding door of this embodiment can flexibly accommodate adjustments to the length of the connecting portion 11 and changes to the shape of the lower end of the door trim 502. Furthermore, the power supply device 1 for the sliding door of this embodiment can be easily adapted to various situations by providing the reversal mechanism 40 as an assembly member that can be attached to the inner panel 501 or door trim 502 with screws or the like.
