[0004] [Patent Document 1] JP 2013-159224 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the vehicle body moves relative to the suspension system while driving. Therefore, when wiring a harness between the vehicle body and the suspension system, it is necessary to add a fixing member to prevent vibrations from the harness on the vehicle body side from being transmitted to the harness connector on the suspension system side. However, adding a new fixing member to prevent vibrations would cause problems such as increased manufacturing costs.

[0006] An object of the present invention is to provide a harness routing structure that suppresses vibration while keeping manufacturing costs down. [Means for solving the problem]

[0010] A harness arrangement structure according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings. Note that the present invention is not limited to the following embodiment, and the components in the following embodiment include those that a person skilled in the art can easily conceive, those that are substantially the same, and those that are within the scope of what is called equivalent. Furthermore, various omissions, substitutions, modifications, and combinations of the components can be made without departing from the gist of the following embodiment.

[0011] <Embodiment> As an example of the harness routing structure of this embodiment, an application to a handle-type electric wheelchair called a senior car will be shown. Note that the harness routing structure of this embodiment is not limited to senior cars, but can be applied to any vehicle body having a suspension device that suspends the wheels from the vehicle body. In the following, the vehicle body with respect to the suspension device includes not only the frame of the vehicle body but also parts that move integrally with the frame.

[0012] First, the overall configuration of the senior car will be described with reference to FIG. 1, and the harness routing structure of this embodiment will be described in detail with reference to FIGS.

[0013] Fig. 1 is a perspective view showing an example of a senior car to which a harness arrangement structure according to an embodiment is applied. The senior car 1 shown in Fig. 1 has a steering shaft portion 14 of a mechanism that applies a steering angle to front wheels (wheels 12 and 13) according to the turning angle of a handlebar 11.

[0014] Although a bar handle is shown as an example of the handle 11, handles of other shapes, such as a loop handle, may also be used.

[0015] The handlebar 11 is provided with an instrument meter 111, a reverse switch 112, a brake lever 113, an accelerator lever 114, etc. The braking method may be manual braking using the brake lever 113, or an electromagnetic brake, or a combination of multiple braking methods may be used.

[0016] A bottom surface 22 is disposed near the center of a frame 21 of the vehicle body, and a seat 23 is provided whose height is adjusted relative to the bottom surface 22. Control devices 24, 25 are provided below the seat 23. The control devices 24, 25 are supplied with power from a rechargeable battery mounted on the vehicle body.

[0017] The rear wheels (wheels 31 and 32) that swing up and down relative to the vehicle body while traveling are provided on the rear side of the frame 21. The wheels 31, 32 are provided on suspension devices 33, 34, respectively, and are suspended from the frame 21 of the vehicle body by the suspension devices 33, 34. The suspension devices 33, 34 are connected to the vehicle body frame via suspensions 35, 36. With this configuration, the wheels 31, 32 swing up and down relative to the vehicle body together with the suspension devices 33, 34, respectively. The suspensions 35, 36 use dampers that absorb and reduce the up and down movement.

[0018] It has been explained that the wheels 31, 32 swing up and down relative to the vehicle body together with the suspension devices 33, 34, respectively. However, this is synonymous with the vehicle body swinging up and down when viewed from the suspension devices 33, 34 side.

[0019] As an example, the wheels 31 and 32 are driven by motors. The electric wires on the rear side, such as the power supply lines that supply power to the motors and the signal lines to the sensors and various devices, are connected from the suspension devices 33 and 34 to the control devices 24 and 25 by harnesses 43 and 44. The harness wiring structure 30 for this portion will be described in detail with reference to Fig. 2 and subsequent figures. The harness is a bundle of electric wires that bundles together the power supply lines, signal lines, and other electric wires.

[0020] The electric wires for the instruments etc. at the front of the vehicle body are passed from the steering side under the bottom surface 22 of the vehicle body and connected to the control devices 24, 25 at the rear by harnesses. The number and positions of the control devices 24 and 25 are merely examples, and are not limited thereto. In addition to the control devices 24 and 25, relay devices and the like may be provided.

[0021] Fig. 2 is a partially enlarged view of the vicinity of the suspension devices 33, 34. In Fig. 2, the part 211 shown in Fig. 1 has been removed so that the entire harness routing structure 30 can be easily seen. Also, in Fig. 2, the rear wheels (wheels 31 and 32) of each suspension device 33, 34 are omitted from the drawing.

[0022] The first support member 210 and the second support member 212 are parts on the vehicle body side that are fixed to the frame 21 shown in Fig. 1. Of these, the second support member 212 is a part that supports the suspension devices 33, 34 so that they can swing, has a shaft portion parallel to the +X axis, and supports the suspension devices 33, 34 via the shaft portion so that they can swing about the axis.

[0023] One end of each of the suspensions 35, 36 is connected to the upper surface of each of the suspensions 33, 34, and each of the suspensions 35, 36 is disposed at an angle toward the first support portion 210. The other end of each of the suspensions 35, 36 is connected to a frame (not shown) on the vehicle body side. With this configuration, the suspensions 33, 34 swing about the shaft of the second support member 212 while being controlled by the stroke of each of the suspensions 35, 36, causing the wheels 31, 32 to move up and down.

[0024] The suspensions 33, 34 are provided with connectors 51, 52 supported by brackets 37, 38, respectively. Of these, the connector 51 on one side is a connector that is wired and connected to sensors, devices, etc. provided on the suspension 33 side. The connector 52 on the other side is a connector that is wired and connected to sensors, devices, etc. provided on the other suspension 34 side.

[0025] The main configuration of the harness routing structure on the suspension 33 side is the same as that of the harness routing structure on the other suspension 34 side. Note that, although Fig. 2 shows a configuration in which a bracket 39 is further added to the harness routing structure on the other suspension 34 side, the bracket 39 may be provided as necessary.

[0026] First, the main configuration will be described with reference to the harness routing structure on the suspension device 33 side. The connector 51 is connected to a vehicle body side connector provided on the vehicle body via a harness 43. The harness 43 is connected to the vehicle body side connector or directly to the control device 24 through the left side surface of the first support part 210 on the side where the control device 24 is provided.

[0027] The harness 43 is inserted through the bendable tubular member 41 with some slack, and is fixed by a first fixing member 55 and a second fixing member 53. The tubular member 41 is, for example, a resin tube. The inner diameter of the tubular member 41 is larger than the diameter of the harness 43, and a gap 400 is formed between the harness 43 and an inner surface 411 of the tubular member 41 as shown in Fig. 3B, Fig. 3C, Fig. 4, etc. The tubular member 41 has such rigidity that the gap 400 between the harness 43 and the tubular member 41 is maintained to a certain degree even when the outer periphery of the tubular member 41 is fixed by a fixing member.

[0028] The first fixing member 55 supports the outer periphery of the tubular member 41 and fixes the tubular member 41 to the second support portion 212. The second fixing member 53 fixes the terminal portion 410 side of the tubular member 41 extending from the first fixing member 55 to the suspension device 33.

[0029] The second fixing member 53 supports the outer periphery of the terminal portion 410 of the tubular member 41 and the outer periphery of the harness 43 exposed from the terminal portion 410 of the tubular member 41, and fixes them integrally to the suspension device 33. The second fixing member 53 has a band binding portion b for supporting the outer periphery of the terminal portion 410 of the tubular member 41, and a band binding portion a for supporting the outer periphery of the harness 43. The terminal portion 410 is in a range having a width from the terminal of the tubular member 41. The band binding portion b may bind the outer periphery of the tubular member 41 at an optimal position from the terminal of the tubular member 41.

[0030] The harness 43 extending from the second fixing member 53 branches into the electric wires 45 , which are connected to the corresponding connectors 51 .

[0031] The harness 43 of the tubular member 41 extending from the first fixing member 55 to the opposite side to the terminal portion 410 on the second fixing member 53 side is fixed to the first support portion 210 by the third fixing member 57, but fixing at this portion is one example. Fixing by the third fixing member 57 may be at another position on the vehicle body side closer to the control device 24. One example of the third fixing member 57 is a cable tie.

[0032] In addition, in this embodiment, the band b is used to support two points, but the band may be any type that can support two points. For example, tape may be used.

[0033] Fig. 3A is a development view showing an example of a part applied to the second fixing member 53 shown in Fig. 2. Fig. 3B is a view of the second fixing member 53 shown in Fig. 2 when viewed from the -Y direction shown in Fig. 2. Fig. 3C is a view of the second fixing member 53 shown in Fig. 2 when viewed from the +Y direction shown in Fig. 2. Fig. 3D is an explanatory diagram relating to the fixing of the second fixing member 53 and the suspension device 33.

[0034] 3A, the second fixing member 53 has a belt portion a1, a belt portion b1, a belt insertion hole 531, a belt insertion hole 532, a connecting portion 536, and a fixing portion 533. The second fixing member 53 is made of a material such as resin.

[0035] In this example, the belt portion a1 and the belt insertion hole 531 correspond to the band binding portion a, and the belt portion b1 and the belt insertion hole 532 correspond to the band binding portion b.

[0036] Belt a1 and belt b1 can be curved, and are used by inserting the upper tip of belt a1 into belt insertion hole 531 in the +X-axis direction to fasten belt a1, and inserting the upper tip of belt b1 into belt insertion hole 532 in the +X-axis direction to fasten belt b1.

[0037] The reason why the belt portion a1 and the belt b1 have different lengths is that they are used to bundle objects with different diameters. The lengths of the belt portion a1 and the belt b1 are not limited. The lengths of the belt portion a1 and the belt b1 may be the same to match the larger diameter, or the ends may be cut after the objects are bundled together.

[0038] Both the band binding part a and the band binding part b are molded to prevent the belt part a1 and the belt part b1 from slipping out. In this example, many tooth-like notches 535 and 534 are molded in the length direction of the belt part a1 and the belt part b1, respectively, and a structure is provided on the belt insertion hole 531 and the belt insertion hole 532 side to prevent the belt part a and the belt part b from returning and to lock them.

[0039] Band binding portion a and band binding portion b are integrally formed by connecting portion 536 as shown in FIG. 3A, and can be fixed integrally to suspension device 33 by fixing portion 533.

[0040] The second fixing member 53 is fixed by, for example, fitting a protruding fixing portion 533 into a predetermined hole 330 (see FIG. 3D) provided on the upper surface of the suspension device 33. The fixing portion 533 may be formed integrally with a connecting portion 536 of the second fixing member 53, or may be provided separately from the second fixing member 53. The second fixing member 53 may be in the form of a screw, a bolt, or the like.

[0041] Next, the fixed state in which the outer periphery of the terminal portion 410 of the tubular member 41 and the outer periphery of the harness 43 exposed from the terminal portion 410 of the tubular member 41 are supported by band binding portion b and band binding portion a, respectively, in the arrangement shown in Figure 2 will be described with reference to Figures 3B and 3C, respectively.

[0042] 3B, in the band fastening portion b, the belt portion b1 is wound around the outer periphery of the terminal portion 410 of the tubular member 41, and a tip portion of the belt portion b1 is inserted into the belt insertion hole 532, and the belt portion b1 fastens the terminal portion 410 of the tubular member 41. The tubular member 41 is supported in that position because the belt portion b1 is wound in close contact with the outer periphery of the terminal portion 410 of the tubular member 41 and is fastened by a number of tooth-like notches 535 and a locking structure that prevents the belt insertion hole 532 from returning.

[0043] 3C, in the band fastening portion a, the belt portion a1 is wound around the outer periphery of the harness 43 exposed from the terminal portion 410 of the tubular member 41, and the tip portion of the belt portion a1 is inserted into the belt insertion hole 531 to fasten the harness 43. The harness 43 is supported in that position because the belt portion a1 is wound in close contact with the outer periphery of the harness 43 and fastened by the numerous tooth-like notches 534 and a locking structure that prevents the belt insertion hole 531 from returning.

[0044] Fig. 4 is a diagram showing an example of the configuration of the first fixing member 55. The example of the first fixing member 55 shown in Fig. 4 has a configuration that supports the outer periphery of the tubular member 41 so as to allow the tubular member 41 to rotate. Note that the P direction shown in Fig. 4 corresponds to the P direction shown in Fig. 2.

[0045] 4 is a corrugated clamp, which is applicable when a corrugated tube having grooves at predetermined intervals along the longitudinal direction of the tubular member 41 is used as the tubular member 41. This corrugated clamp is available in a number of types (sizes) suited to different diameters (e.g., D=10, D=12), and a clamp of a size that fits closely to the outer periphery of the tubular member 41 is used.

[0046] The first fixing member 55 of the example shown in FIG. 4 has convex structures 553 and 554 on the inner periphery of the first fixing member 55 into which grooves provided around the periphery of the tubular member 41 are inserted.

[0047] After the tubular member 41 is placed on the first part 552 of the first fixing member 55, a tip portion of the second part 551 of the first fixing member 55 is inserted into the insertion opening 555 of the first part 552 and the second part 551 is locked via a notch portion inside the insertion opening 555, so that the tubular member 41 is rotatably supported in the first fixing member 55. The first fixing member 55 is fixed to the second support part 212 by the fixing portion 556, so that the tubular member 41 is rotatably supported with respect to the second support part 212.

[0048] According to this configuration, in the first fixing member 55, the tubular member 41 is supported so as to be rotatable about the axis of the tubular member 41, and movement of the tubular member 41 in the axial direction can also be prevented. The combination of the first fixing member 55 and the tubular member 41 is an example and is not limited thereto. When a protective tube without a groove is used as the tubular member 41, the rotation of the tubular member 41 or the movement of the tubular member 41 in the axial direction can be restricted by adjusting the tightening of the first fixing member 55.

[0049] Next, the harness routing structure of the other suspension 34 shown in Fig. 2 will be described. The harness routing structure of the other suspension 34 differs from the harness routing structure of the suspension 33 described so far in that a bracket 39 is further added.

[0050] The rest are generally the same, with the third fixing member 58 corresponding to the third fixing member 57, the first fixing member 56 corresponding to the first fixing member 55, the second fixing member 54 corresponding to the second fixing member 53, the tubular member 42 corresponding to the tubular member 41, the terminal portion 420 corresponding to the terminal portion 410, the harness 44 corresponding to the harness 43, the electric wire 46 corresponding to the electric wire 45, the connector 52 corresponding to the connector 51, and the bracket 38 corresponding to the bracket 37. The connector 52 is connected to a vehicle body side connector or directly to the control device 25 through the right side surface of the first support portion 210 on the side where the control device 25 is provided.

[0051] Fig. 5 is an explanatory diagram of a harness routing structure provided with a bracket 39 in the other suspension device 34. Fig. 5 shows a schematic configuration diagram of the other suspension device 34 side as viewed from the rear of the vehicle body (-X axis direction).

[0052] In Fig. 5, the same numbers are used for parts corresponding to the configuration shown in Fig. 2. In Fig. 5, the upward arrow +r and the downward arrow -r indicate the directions in which the other suspension device 34 swings in an arc shape around the shaft portion 213 relative to the second support member 212 of the main body.

[0053] 5, the tubular member 42 is fixed to the second support member 212, which is part of the frame configuration on the main body side, by the first fixing member 56. In this main body configuration, the main body side connector is located at a high position from the suspension device 34, so the exit of the tubular member 42 from the main body side is located at a high position from the suspension device 34. The height of the connector 52 to which the harness 44 is connected is adjusted by the bracket 38, and is set at a height at which the harness 44 is connected horizontally.

[0054] Since the height of the second fixing member 54 cannot be adjusted when an existing member is used, a bracket 39 of a corresponding height is provided on the suspension device 34, and the second fixing member 54 is fixed on the bracket 39. By providing the bracket 39 in this manner, the harness 44 is routed horizontally, thereby reducing the concentration of stress on the harness 44 in the Z direction.

[0055] Furthermore, the same effect as bracket 39 can be obtained by providing a second fixing member 54 with the connecting portion thereof previously set to the same height as bracket 39, and then fitting and fixing the fixing portion of the connecting portion into the hole in suspension device 34.

[0056] Next, a description will be given of the common actions and effects of the harness structure of this embodiment in the suspension 33 and the other suspension 34. For the sake of common explanation, the suspension 33 will be taken as an example.

[0057] When viewed from the vehicle body side, the suspension device 33 moves, and this movement causes the harness 43 in this section to flap. For this reason, the harness routing structure in this section can be prevented from interfering with the surroundings by inserting the harness 43 into the tubular member 41.

[0058] On the other hand, in the wiring structure on the connector 51 side, if the outer periphery of the tubular member 41 is simply fixed at the position of the second fixing member 53, vibrations caused by flapping of the harness 43 between the main body frame and the suspension device 33 will be transmitted to the connector 51 side. To prevent this, a fixing member for preventing vibrations is required between the connector 51 and the fixing position of the tubular member 41 to the second fixing member 53 (hereinafter referred to as fixing position 2').

[0059] However, when a fixing member for preventing vibration is provided between the connector 51 and the fixing position 2', restrictions arise due to the production process of the harness 43. For example, in the production process of the harness 43, a jig is used to form the harness 43 and attach the fixing member. Since a jig that matches the distance between the third fixing member 55 and the fixing position 2' is used, the same jig is also used to fix the fixing member for preventing vibration.

[0060] In this case, if the third fixing member 55 and the fixing position 2' are designed to be located apart from each other, the position of the additional fixing member will also be designed to be away from the fixing position 2' because the same jig is used, and it will be located close to the connector 51, which will cause a problem with the installation space. Since there is also a limit to the wiring space on the top surface of the suspension device 33, installation may be difficult.

[0061] 6, when the third fixing member 55 and the fixing position 2' of the second fixing member 53 are arranged close to each other, like the fixing member 65 and the fixing member 63 as shown in FIG. 6, the fixing member for preventing vibration is in the position shown by the fixing member 61, and the harness 43 from the fixing member 65 to the connector 51 becomes shorter, so that the connection direction of the connector 51 is perpendicular to the first support member 210. In FIG. 6, the fixing member 66 and the fixing member 64 are also arranged close to each other on the suspension device 34 side, and the fixing member 62 for preventing vibration is provided, so that the connection direction of the connector 52 is perpendicular to the first support member 210.

[0062] On the other hand, in the harness routing structure of this embodiment, the second fixing member 53 is used to support and fix the outer periphery of the terminal portion 410 of the tubular member 41 and the outer periphery of the harness 43 exposed from the terminal portion 410 of the tubular member 41 in one place. This makes it possible to reduce the number of jigs in the production process by one, thereby reducing the manufacturing cost. In addition, the number of holes into which the protruding fixing portion 533 is fitted can be minimized, which prevents the suspension device 33 from becoming fragile.

[0063] Moreover, in the harness routing structure of this embodiment, by supporting the outer periphery of the terminal portion 410 of the tubular member 41 and the outer periphery of the harness 43 exposed from the terminal portion 410 at the position of the second fixing member 53, it is possible to effectively avoid flapping of the harness 43 on the tubular member 41 side, relieve stress on the harness 43, and suppress vibration toward the connector 51 at that position. Therefore, since there is no need to add a fixing member for preventing vibration on the connector 51 side, it is possible to utilize the space on the upper surface of the suspension device 33 for routing, and it is also possible to suppress stress concentration on the harness 43 inside the tubular member 41.

[0064] 2, in the harness routing structure of this embodiment, the connector 51 is disposed via the bracket 37 on the front side (-X axis direction) of the suspension 33 so as to face the rear (+X axis direction) of the vehicle body. The harness 43 is routed from the main body frame side in a U-shaped path, and an end of the harness 43 is connected to the connector 51. In such a U-shaped path routing structure, the harness 43 is kept pushed in the rearward direction (+X axis direction) due to the rigidity of the harness 43, so that the movement of the second fixing member 53 relative to the suspension 33 can be suppressed.

[0065] For example, as shown in FIG. 3D, a hole 330 of a predetermined size for fixing the second fixing member 53 is provided on the upper surface of the suspension device 33. Here, for example, an elongated hole is set as the hole 330. The second fixing member 53 can be fixed to the suspension device 33 by fitting the fixing portion 533 of the second fixing member 53 into the hole 330 on the upper surface of the suspension device 33. The fixing portion 533 of the second fixing member 53 is an elastic body in which an inverted triangular portion closes by an external force, for example. When the fixing portion 533 of the second fixing member 53 is fitted into the hole 330 of the suspension device 33, the inverted triangular portion returns to its original shape after passing through the hole 330, and the second fixing member 53 is fixed to the hole 330.

[0066] The second fixing member 53 is fixed by fitting the fixing portion 533 into the hole 330 at the position of the locking portion. However, since the size of the locking portion of the fixing portion 533 and the size of the hole 330 are different, if there is a gap between them, the second fixing member 53 may move due to vibration, for example by shifting in the direction of the gap. In the U-shaped path wiring structure, the harness 43 is pushed backward (in the +X-axis direction), so that even if there is a gap between the locking portion of the fixing portion 533 and the hole 330, the second fixing member 53 acts to constantly crush the gap on the rear side of the hole 330, so that the second fixing member 53 is constantly pressed against the rear side, and the movement of the second fixing member 53 relative to the suspension device 33 is kept suppressed. Note that the wiring of the U-shaped path is not limited to the U-shaped path in which the harness 43 is pushed backward (in the +X-axis direction) as shown in FIG. 2. In accordance with the wiring of the harness 43 on the main body frame side, such as wiring the harness 43 on the rear side (+X axis direction) instead of the front side (-X axis direction) on the main body frame side, the harness 43 may be wired in a U-shaped path in a direction pushed in the opposite forward side (-X axis direction). In the case of wiring in the latter U-shaped path, in the suspension device 33 shown in FIG. 2, the connector 51 is disposed at a position on the rear side (+X axis direction) of the suspension device 33 so as to face the front (-X axis direction) of the vehicle body. The harness 43 is wired in a U-shaped path that is pushed in the forward (-X axis direction) direction from the main body frame side, and an end of the harness 43 is connected to the connector 51. In the case of wiring in the latter U-shaped path, the second fixing member 53 is always pressed against the hole 330 in the forward side (-X axis direction).

[0067] In addition, as long as the second fixing member 53 is a fixing member that has the function of supporting two places (multiple places) with one fixing member, an existing fixing member can be used as appropriate. Furthermore, an existing corrugated tube and corrugated clamp can also be used instead. Therefore, there is no need to develop new parts, and the manufacturing costs can be reduced accordingly.
