Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the linear body holding structure as in Patent Document 1 above, the linear body can be positioned in the radial direction by hooking the linear body on the hook-shaped holding portion, but the linear body cannot be positioned in the length direction. For this reason, a positional deviation occurs in the length direction of the linear body, a portion where the linear body is loose occurs, and there is a possibility that noise due to the vibration of the linear body or disconnection of the linear body may occur. In order to regulate the positional deviation in the length direction of the linear body, it is also conceivable to arrange a plurality of holding portions close to each other and alternately arrange the plurality of holding portions so that the linear body is arranged in a waveform. However, in such an arrangement of the holding portions, the set number of the plurality of holding portions increases, which causes an increase in cost due to the increase in the holding portions and a decrease in the assemblability of the linear body with respect to the holding portions.

[0005] This invention has been made in view of the problems of the prior art described above. The object of this invention is to provide a linear body holding structure and a linear body holding method that can suppress positional displacement in the longitudinal direction of a linear body with a simple structure. [Means for solving the problem]

[0006] The linear body holding structure according to this embodiment comprises a bendable linear body, an arrangement member on which the linear body is arranged, and a holding portion provided on the arrangement member for holding the linear body, wherein the holding portion includes a first holding portion for holding the linear body in a straight line, a second holding portion arranged on one side of the first holding portion for holding the bent state of the linear body exposed from the first holding portion, and a third holding portion arranged on the other side of the first holding portion for holding the bent state of the linear body exposed from the first holding portion.

[0007] A linear body holding method according to this embodiment is a method for holding a linear body to a holding portion of an arrangement member provided with a holding portion having: a first holding portion for holding a bendable linear body in a straight line; a second holding portion disposed on one side of the first holding portion and exposing the linear body to the first holding portion and holding the bent state of the linear body; and a third holding portion disposed on the other side of the first holding portion and exposing the linear body to the first holding portion and holding the bent state of the linear body, comprising: a first step of holding the linear body to the first holding portion; a second step of bending the linear body exposed from one side of the first holding portion and holding it to the second holding portion; and a third step of bending the linear body exposed from the other side of the first holding portion and holding it to the third holding portion.

[Modes for carrying out the invention]

[0010] The linear body holding structure and linear body holding method according to this embodiment will be described in detail below with reference to the drawings. Note that the dimensional ratios in the drawings are exaggerated for illustrative purposes and may differ from the actual ratios.

[0011] As shown in Figure 1, the linear body holding structure 1 according to this embodiment is applied to a so-called bracket rear bumper, which is located at the bottom of a vehicle and holds a kick sensor that opens and closes the cargo compartment door without touching the vehicle body by sensing the movement of a foot.

[0012] As shown in Figures 1 to 10, the linear body holding structure 1 comprises a linear body 3, an arrangement member 5, and a holding part 7.

[0013] As shown in Figures 1-6 and 8-10, the linear body 3 is an electric wire that electrically connects the controller C and the electrostatic sensor S. The controller C has a circuit formed to control the electrostatic sensor S. Multiple electrostatic sensors S (two in this case) are used. The electrostatic sensor S is formed by covering a core made of synthetic resin, for example, with a mesh made of a conductive material, and covering its outer circumference with an outer sheath. The electrostatic sensor S has high rigidity and is difficult to bend. For this reason, the electrostatic sensor S is arranged linearly with respect to the arrangement member 5. The linear body 3 is electrically connected to the end of the electrostatic sensor S. The end of the linear body 3 opposite to the electrostatic sensor S is electrically connected to the controller C via a connector. The linear body 3 is bendable. For this reason, the linear body 3 is arranged bent with respect to the arrangement member 5 to avoid interference with surrounding members.

[0014] As shown in FIG. 1, the placement member 5 is made of an insulating material such as synthetic resin. The placement member 5 is fixed to the vehicle via a plurality of mounting portions. On the side of the placement member 5 facing the vehicle, an electrostatic sensor S is linearly arranged, and the linear body 3 is arranged in a predetermined shape. A plurality (here, eight) of sensor holding portions 11 are provided at the portion of the placement member 5 where the electrostatic sensor S is arranged. Six of the plurality of sensor holding portions 11 are formed in a C-shaped hook form and support the electrostatic sensor S by engaging to hook the electrostatic sensor S. Two of the plurality of sensor holding portions 11 are composed of a pair of elastically deformable locking claws and support the electrostatic sensor S by engaging with the outer surface of the electrostatic sensor S. At the portion of the placement member 5 where the linear body 3 is arranged, a plurality (here, six) of holding portions 7 for holding the linear body 3 bent into a predetermined shape are provided.

[0015] As shown in FIGS. 1 to 10, the holding portion 7 is made of an insulating material such as synthetic resin. The holding portion 7 is, for example, formed separately from the placement member 5 and then provided integrally with the placement member 5 by welding or the like. The plurality of holding portions 7 are arranged on the placement member 5 corresponding to the predetermined arrangement shape of the linear body 3. Each of the plurality of holding portions 7 includes a first holding portion 13, a second holding portion 15, and a third holding portion 17.

[0016] The first holding portion 13 includes a pair of opposing walls 19, 19. The pair of opposing walls 19, 19 protrude upward in a direction (here, a direction substantially perpendicular) intersecting the planar direction of the placement member 5 from the side of the placement member 5. The pair of opposing walls 19, 19 extend linearly along a direction parallel to the planar direction of the placement member 5. The space between the opposing surfaces 21, 21 of the pair of opposing walls 19, 19 is uniform over the extending direction (length direction) and is set to be approximately equal to the diameter of the linear body 3. The space formed between the opposing surfaces 21, 21 of the pair of opposing walls 19, 19 and the bottom wall 23 on the side of the placement member 5 is opened upward so that the linear body 3 can be inserted, and constitutes a first accommodating portion 25 capable of accommodating the linear body 3 linearly. In the first accommodating portion 25, the middle portion of the linear body 3 is inserted through the opening and accommodated, and the middle portion of the linear body 3 is held linearly. Above the pair of opposing walls 19, 19, a plurality (here, six) of first guide portions 27 are provided and inclined so as to spread upward from the opening of the first accommodating portion 25. When the linear body 3 is accommodated in the first accommodating portion 25, the first guide portion 27 guides the linear body 3 toward the opening of the first accommodating portion 25, improving the assembling property of the linear body 3 with respect to the first holding portion 13. For example, a pair of elastically deformable locking claws engaged with the linear body 3 may be provided around the opening of the first accommodating portion 25.

[0017] A first support point 29 and a second support point 31 are provided at both ends of the pair of opposing walls 19, 19 in the extension direction (length direction). The first support point 29 is provided on one of the opposing walls 19 and is at one end of the opposing wall 19 in the extension direction (length direction). The first support point 29 serves as a fulcrum when bending the linear body 3 exposed from the first housing section 25 toward the second holding section 15. The second support point 31 is provided on the other opposing wall 19 and is at the other end of the opposing wall 19 in the extension direction (length direction). The second support point 31 serves as a fulcrum when bending the linear body 3 exposed from the first housing section 25 toward the opposite side of the first support point 29 (towards the third holding section 17). By providing a first support point 29 and a second support point 31 at both ends of the pair of opposing walls 19, 19, the linear body 3 held by the first holding part 13 can be easily bent, thereby improving ease of assembly. When both sides of the linear body 3 exposed from the first housing part 25 are bent in the same direction, the ends of one opposing wall 19 or the other opposing wall 19 in the extending direction (length direction) become the first support point 29 and the second support point 31, respectively. The first holding part 13 (first housing part 25) is provided with a second holding part 15 and a third holding part 17 on both sides in the extending direction (length direction).

[0018] The second holding portion 15 is located on one side of the first holding portion 13 where the first support portion 29 is located. The second holding portion 15 comprises a second side wall 33 and a second upper wall 35. The second side wall 33 protrudes upward from the side of the placement member 5 in a direction intersecting the planar direction of the placement member 5 (in this case, a nearly perpendicular direction). The second side wall 33 extends linearly along a direction parallel to the planar direction of the placement member 5 and intersecting the opposing wall 19 of the first holding portion 13 (in this case, a nearly perpendicular direction). The second upper wall 35 extends in a plate-like manner along a planar direction parallel to the planar direction of the placement member 5, as a continuous member with the second side wall 33 from the end of the second side wall 33 opposite to the placement member 5. The space formed between the inner surface of the second side wall 33 and the inner surface of the second upper wall 35 constitutes a second housing section 37, in which the side opposite the second side wall 33 is opened to allow insertion of the linear body 3, and the linear body 3 can be accommodated in a straight line. The opening of the second housing section 37 is oriented in a direction that intersects (in this case, is approximately perpendicular) with the opening of the first housing section 25 of the first holding section 13. The linear body 3, which is exposed from one side of the first holding section 13 and bent at the first support section 29, is inserted through the opening into the second housing section 37 and accommodated, holding the linear body 3 in a straight line. The width (height) of the opening of the second housing section 37 is set to be approximately the same as the depth of the first housing section 25. By setting the width of the opening of the second housing section 37 to be the same as the depth of the first housing section 25, it is possible to easily insert the linear body 3, which is bent at the first support section 29, into the second housing section 37 from the opening, thereby improving ease of assembly.

[0019] The second upper wall 35 is provided with a second guide portion 39 at its extending end, which is inclined to widen laterally (to the right in Figure 6) from the opening of the second housing portion 37. The second guide portion 39 guides the linear body 3 toward the opening of the second housing portion 37 when the linear body 3 is housed in the second housing portion 37, improving the ease of assembling the linear body 3 to the second holding portion 15. The lower end of the second guide portion 39 on the second upper wall 35 is provided with a second engaging portion 41 that protrudes downward to narrow the opening of the second housing portion 37. The second engaging portion 41 can engage with the linear body 3 housed in the second housing portion 37. By engaging the second engaging portion 41 with the linear body 3, the linear body 3 can be prevented from coming out of the second housing portion 37, and the linear body 3 can be stably held in the second holding portion 15.

[0020] The third holding portion 17 is located on the other side of the first holding portion 13 where the second support portion 31 is located. The third holding portion 17 is formed symmetrically with respect to the second holding portion 15, with the first holding portion 13 in between. Here, the third holding portion 17 shown in Figure 6 is assumed to be formed symmetrically with respect to the second holding portion 15. The third holding portion 17 comprises a third side wall 43 and a third upper wall 45. The third side wall 43 protrudes upward from the side of the placement member 5 in a direction intersecting the planar direction of the placement member 5 (in this case, a nearly perpendicular direction). The third side wall 43 extends linearly along a direction parallel to the planar direction of the placement member 5 and intersecting the opposing wall 19 of the first holding portion 13 (in this case, a nearly perpendicular direction). The third upper wall 45 is a single member continuous with the third side wall 43, extending in a plate-like shape along a planar direction parallel to the planar direction of the arrangement member 5 from the end of the third side wall 43 opposite to the arrangement member 5. The space formed between the inner surface of the third side wall 43 and the inner surface of the third upper wall 45 constitutes a third housing section 47, in which the side opposite to the third side wall 43 is opened to allow insertion of the linear body 3, and the linear body 3 can be accommodated in a straight line. The opening of the third housing section 47 is oriented in a direction that intersects (in this case is almost perpendicular) with the opening of the first housing section 25 of the first holding section 13, and is oriented opposite to the opening of the second housing section 37. The linear body 3, exposed from the other side of the first holding section 13 and bent at the second support section 31, is inserted through the opening into the third housing section 47 and accommodated, holding the linear body 3 in a straight line. The width (height) of the opening of the third housing section 47 is set to be approximately the same as the depth of the first housing section 25. By setting the width of the opening of the third housing section 47 to be the same as the depth of the first housing section 25, the linear body 3 bent at the second support section 31 can be easily inserted into the third housing section 47 from the opening, thereby improving ease of assembly.

[0021] The third upper wall 45 is provided with a third guide portion 49 at its extending end, which is inclined to widen laterally (to the right in Figure 6) from the opening of the third housing portion 47. The third guide portion 49 guides the linear body 3 toward the opening of the third housing portion 47 when the linear body 3 is housed in the third housing portion 47, improving the ease of assembling the linear body 3 to the third holding portion 17. The lower end of the third guide portion 49 on the third upper wall 45 is provided with a third engaging portion 51 that protrudes downward to narrow the opening of the third housing portion 47. The third engaging portion 51 can engage with the linear body 3 housed in the third housing portion 47. By engaging the third engaging portion 51 with the linear body 3, the linear body 3 can be prevented from coming out of the third housing portion 47, and the linear body 3 can be stably held in the third holding portion 17.

[0022] In this configuration, the linear body 3 held by the holding part 7 has both sides of the linear portion held by the first holding part 13 bent, and the bent state is maintained by the second holding part 15 and the third holding part 17. Since both sides of the linear body 3 exposed from the first holding part 13 are bent, there is no displacement in the length direction. Therefore, there is no excessive placement of the linear body 3 between adjacent holding parts 7, 7, and no loose parts are created on the linear body 3, thereby suppressing noise caused by vibration of the linear body 3 and preventing wire breakage of the linear body 3. In addition, since the linear body 3 is held linearly by the first holding part 13, and the linear body 3 exposed from the first holding part 13 is bent and held by the second holding part 15 and the third holding part 17, complex assembly is not required, improving ease of assembly. Both ends of the linear body 3 exposed from the first holding part 13 are bent in different directions relative to the second holding part 15 and the third holding part 17. By making the bending directions of the linear body 3 different, the positional displacement of the linear body 3 in the longitudinal direction can be restricted with the minimum number of bends in the holding part 7, thereby improving assembly. However, both ends of the linear body 3 exposed from the first holding part 13 may be bent in the same direction. In this case, for example, the linear body 3 exposed from the second holding part 15 and the third holding part 17 can be bent using the ends of the second side wall 33 and the third side wall 43 as pivot points.

[0023] A method for holding the linear body 3 in relation to the holding part 7 will now be described. First, as shown in Figure 8, a portion of the linear body 3 is inserted through the opening of the first housing part 25 of the first holding part 13, and the portion of the linear body 3 is housed in the first housing part 25, thereby holding the portion of the linear body 3 in a straight line in the first holding part 13 (first step). Next, as shown in Figure 9, one side of the linear body 3 exposed from the first holding part 13 is bent toward the second holding part 15. Next, the bent linear body 3 is inserted into the opening of the second housing part 37 of the second holding part 15, and the bent linear body 3 is housed in the second housing part 37, thereby holding the bent linear body 3 in the second holding part 15 (second step). Next, as shown in Figure 10, the other side of the linear body 3 exposed from the first holding part 13 is bent toward the third holding part 17, which is on the opposite side from the one side. Then, the bent linear body 3 is inserted into the opening of the third housing portion 47 of the third holding portion 17, and the bent linear body 3 is housed in the third housing portion 47, thereby holding the bent linear body 3 in the third holding portion 17 (third step). This holding of the linear body 3 in relation to the holding portion 7 is performed at each holding portion 7, completing the holding of the linear body 3 to the arrangement member 5.

[0024] Here, the second engaging portion 41 and the third engaging portion 51 in the second holding portion 15 and the third holding portion 17 may be provided independently of the second housing portion 37 and the third housing portion 47, as shown in Figures 11 to 13.

[0025] The second engaging portion 41a and the third engaging portion 51a shown in Figure 11 are formed in a C-shaped hook form with openings in the same direction as the openings of the second housing portion 37 and the third housing portion 47. When the linear body 3 exposed from the first holding portion 13 is bent, the bent linear body 3 is inserted through the openings and engages with the second engaging portion 41a and the third engaging portion 51a. The engagement of the second engaging portion 41a and the third engaging portion 51a with the linear body 3 can hold the bent state of the linear body 3.

[0026] The second engaging portion 41b and the third engaging portion 51b shown in Figure 12 are formed in an L-shaped hook form with openings facing the opposite direction to the openings of the second housing portion 37 and the third housing portion 47. When the linear body 3 exposed from the first holding portion 13 is bent, the second engaging portion 41b and the third engaging portion 51b engage with the bent linear body 3, causing it to move over the bent linear body 3 and sandwich it between the second housing portion 37 and the third housing portion 47. The engagement of the second engaging portion 41b and the third engaging portion 51b with the linear body 3 allows the bent state of the linear body 3 to be maintained.

[0027] The second and third engaging portions 41c and 51c shown in Figure 13 protrude from the free end side of an elastically deformable locking piece, having engaging surfaces that face the openings of the second and third housing portions 37 and 47. When the linear body 3 exposed from the first holding portion 13 is bent, the second and third engaging portions 41c and 51c slide against the bent linear body 3, causing the locking piece to elastically deform. After the sliding with the linear body 3 is completed, the locking piece returns to its original state from elastic deformation, and the engaging surfaces engage with the linear body 3 between the second and third housing portions 37 and 47, sandwiching it between them. The engagement of the second and third engaging portions 41c and 51c with respect to the linear body 3 allows the bent state of the linear body 3 to be maintained.

[0028] Such a linear body holding structure 1 includes a bendable linear body 3, an arrangement member 5 on which the linear body 3 is placed, and a holding part 7 provided on the arrangement member 5 for holding the linear body 3. The holding part 7 has a first holding part 13 that holds the linear body 3 in a straight line, and a second holding part 15 that is located on one side of the first holding part 13 and holds the bent state of the linear body 3 that is exposed from the first holding part 13. The holding part 7 also has a third holding part 17 that is located on the other side of the first holding part 13 and holds the bent state of the linear body 3 that is exposed from the first holding part 13.

[0029] The linear body 3, held linearly by the first holding part 13, has both ends exposed from the first holding part 13 in the longitudinal direction bent, so there is no displacement in the longitudinal direction. As a result, there are no loose parts in the linear body 3, and noise caused by vibration of the linear body 3 and wire breakage of the linear body 3 can be suppressed. In addition, since the linear body 3 is held linearly by the first holding part 13 and the exposed parts of the linear body 3 are bent and held by the second holding part 15 and the third holding part 17, complex assembly is not required, and ease of assembly can be improved.

[0030] Therefore, with such a linear body holding structure 1, it is possible to suppress the positional displacement of the linear body 3 in the longitudinal direction with a simple structure.

[0031] Furthermore, the linear body 3 is bent in different directions relative to the second holding portion 15 and the third holding portion 17.

[0032] Therefore, the positional displacement in the longitudinal direction of the linear body 3 can be restricted with the minimum number of bends in the holding part 7, thereby improving ease of assembly.

[0033] Furthermore, the first holding portion 13 has a pair of opposing walls 19, 19 in which the linear body 3 is arranged linearly between opposing surfaces 21, 21. A first support portion 29 is provided at one end of the pair of opposing walls 19, 19, which serves as a support point when the linear body 3 is bent toward the second holding portion 15. A second support portion 31 is provided at the other end of the pair of opposing walls 19, 19, which serves as a support point when the linear body 3 is bent toward the third holding portion 17.

[0034] Therefore, the linear body 3 held by the first holding part 13 can be easily bent, improving ease of assembly.

[0035] Furthermore, in the linear body holding method, the holding part 7 has a first holding part 13 that holds a bendable linear body 3 in a straight line, and a second holding part 15 that is positioned on one side of the first holding part 13 and holds the bent state of the linear body 3 that is exposed from the first holding part 13. The holding part 7 also has a third holding part 17 that is positioned on the other side of the first holding part 13 and holds the bent state of the linear body 3 that is exposed from the first holding part 13. The holding part 7 is also provided on the arrangement member 5. The linear body holding method is a method of holding a linear body 3 with respect to the holding part 7. In such a linear body holding method, there is a first step of holding the linear body 3 in the first holding part 13, and a second step of bending the linear body 3 that is exposed from one side of the first holding part 13 and holding it in the second holding part 15. There is also a third step of bending the linear body 3 that is exposed from the other side of the first holding part 13 and holding it in the third holding part 17.

[0036] In the first step, the linear body 3 is held linearly by the first holding part 13. In the second and third steps, both sides of the linear body 3 exposed from the first holding part 13 are bent, so there is no displacement in the length direction. As a result, no loose parts are generated in the linear body 3, and noise caused by vibration of the linear body 3 and breakage of the linear body 3 can be suppressed. In addition, since the linear body 3 is held linearly by the first holding part 13, and the linear body 3 exposed from the first holding part 13 is bent and held by the second holding part 15 and the third holding part 17, complex assembly is not required, and ease of assembly can be improved.

[0037] Therefore, with this linear body holding method, it is possible to suppress positional displacement in the longitudinal direction of the linear body 3 with a simple structure.

[0038] Furthermore, in the third step, the linear body 3 is bent in a direction different from the bending direction of the linear body 3 in the second step.

[0039] Therefore, the positional displacement in the longitudinal direction of the linear body 3 can be restricted with the minimum number of bends in the holding part 7, thereby improving ease of assembly.

[0040] Although this embodiment has been described above, this embodiment is not limited to these, and various modifications are possible within the scope of the gist of this embodiment.

[0041] For example, the linear body is an electric wire, but it is not limited to this; wires, ropes, etc., can also be used as the linear body, and the linear body can be anything as long as it is bendable.

[0042] Furthermore, although the linear body holding structure according to this embodiment is applied to a vehicle, it is not limited to that and may also be applied to buildings and other structures. [Explanation of symbols]
