[0009] Hereinafter, a mounting structure for an electrical component mounted on a vehicle according to an embodiment will be described with reference to the drawings. In the drawings, the front of the vehicle is indicated as FR, the rear of the vehicle as RR, the right side of the vehicle as RH, the left side of the vehicle as LH, the top of the vehicle as UP, and the bottom of the vehicle as DN. In the following description, the terms front, rear, right, left, top, and bottom refer to directions relative to the vehicle, unless otherwise specified. In the following description, elements having the same function will be assigned the same reference numerals, and redundant description will be omitted.

[0010] 1A to 1C , the mounting structure for electrical components mounted on a vehicle according to the embodiment includes a roof panel 11 of the vehicle, a headlining 21 having a hole 22, a harness 31, a bracket 41, and a speaker 51, which is an electrical component. The bracket 41 is fixed to the roof panel 11. The speaker 51 is engaged and held by the bracket 41. The harness 31 is routed between the roof panel 11 and the headlining 21 and connected to a port 52 of the speaker 51. In the vehicle according to the embodiment, speakers are installed on the left and right sides of the front and center of the roof panel 11. The mounting structure will be described below using the mounting structure for the speaker 51 provided on the front left side of the roof panel 11 as an example. The mounting structure for the speaker 51 provided on the front right side of the roof panel 11 is similar, so its description will be omitted. The locations and number of the mounting structures are not limited to those described above.

[0011] The roof panel 11 is a member that constitutes the upper part of the vehicle body and is made of, for example, a steel plate, an aluminum plate, a carbon material, or the like. Fig. 4A illustrates an example of the configuration of the roof panel 11 from the front to the center of the vehicle. As illustrated in the figure, the roof panel 11 may have a panel main body 12, a sunroof opening 13, and a roof reinforcement 14. Note that the configuration of the roof panel 11 from the center to the rear of the vehicle is not illustrated.

[0012] The panel main body 12 is a plate that constitutes the roof panel 11. The sunroof opening 13 is a rectangular opening formed in the center of the panel main body 12 in the vehicle width direction, extending from the front to the center. The roof reinforcement 14 is a member that reinforces the panel main body 12. The roof reinforcement 14 has a rectangular frame shape that surrounds the periphery of the sunroof opening 13. The roof reinforcement 14 is disposed on the interior side of the panel main body 12 (see FIGS. 2 and 4A). A sunroof unit 15 may be attached to the sunroof opening 13. The sunroof unit 15 may include a panel 16 that fits into the sunroof opening 13 and a frame 17. The frame 17 has a rectangular frame shape that surrounds the periphery of the sunroof opening 13. The frame 17 is disposed on the interior side of the roof reinforcement 14 (see FIGS. 2 and 4A).

[0013] 1A to 2, the headlining 21 is disposed on the interior side of the roof reinforcement 14 of the roof panel 11, and constitutes the ceiling of the vehicle compartment 1. The headlining 21 is provided with holes 22 for inserting and accommodating the speakers 51 to the exterior of the vehicle compartment. A harness 31 is routed on the headlining 21.

[0014] The harness 31 is formed by bundling a plurality of electric wires and has a generally circular cross section. A distal end 32 of the harness 31 is connected to a port 52 of the speaker 51. A proximal end 34 of the harness 31 is fixed to the exterior surface 21a of the headlining 21 at fixing points 34a disposed around the hole 22 (see FIG. 1B ). Hereinafter, the portion of the harness 31 between the distal end 32 connected to the port 52 and the proximal end 34 fixed to the fixing points 34a is defined as an excess length portion 33. The proximal end 34 is fixed to the fixing points 34a with adhesive tape, but the fixing method is not limited to this. The configuration of the excess length portion 33 will be described later.

[0015] The bracket 41 is an attachment member for fixing the speaker 51 to the roof panel 11. The bracket 41 is fixed to the roof reinforcement 14 of the roof panel 11 to engage and hold the speaker 51. As illustrated in FIGS. 2 and 3A , the bracket 41 may have a main body 42, a first side wall 43, a second side wall 44, a first opening 45, a second opening 46, a guide portion 47, and legs 48. As illustrated in FIG. 2 , the direction connecting the bracket attachment holes 49 of the legs 48 is substantially aligned with the fore-and-aft direction of the vehicle. Hereinafter, the direction connecting the bracket attachment holes 49 will be referred to as the fore-and-aft direction, and the direction perpendicular to the fore-and-aft direction and the interior direction of the vehicle will be referred to as the width direction.

[0016] The main body portion 42 may have a first main body portion 42a, a step portion 42b extending from an edge of the first main body portion 42a toward the interior of the vehicle cabin, and a second main body portion 42c extending from a lower edge of the step portion 42b toward the base end 34 of the harness 31. The first main body portion 42a and the second main body portion 42c face the roof panel 11. The second main body portion 42c is located farther from the roof panel 11 toward the interior of the vehicle cabin than the first main body portion 42a. The first side wall 43 is formed extending from the left side of the first main body portion 42a in the width direction toward the interior of the vehicle cabin. The second side wall 44 is formed extending from the left side of the second main body portion 42c in the width direction toward the interior of the vehicle cabin. A first opening 45 opening to the left side is defined by the first main body portion 42a, the first side wall 43, the step portion 42b, the second main body portion 42c, and the second side wall 44 (see FIG. 1A ).

[0017] The second main body portion 42c and the second sidewall 44 define a second opening 46 that opens rearward (see FIG. 1A ). A guide portion 47 may be formed on the interior edge of the second sidewall 44 (see FIGS. 1A and 2 ). The guide portion 47 is a slope that slopes toward the interior of the vehicle as it extends rearward away from a port 52 (described later). An end portion 47a of the second sidewall 44 on the second opening 46 side and toward the interior of the vehicle extends rearward toward the base end 34 of the excess length portion 33 along the periphery of the hole 22 in the headlining 21 (see FIGS. 1A and 2 ). In the embodiment, the bracket 41 is formed symmetrically in the width direction, but this is not limited thereto. The first sidewall 43, the second sidewall 44, the first opening 45, the second opening 46, the guide portion 47, and the end portion 47a may be formed on only one of the left and right sides, or may have different shapes on the left and right sides. When the above configuration is formed on both the left and right sides, it is possible to arrange the excess lengths 33 of the multiple harnesses 31. Furthermore, when the above configuration is formed on both the left and right sides, there are more contact points of the bracket 41 with the headlining 21 than when the above configuration is formed on only one of the left and right sides. Therefore, the position of the headlining relative to the bracket 41 is stable.

[0018] The bracket 41 is fixed to the roof reinforcement 14 of the roof panel 11 via bracket mounting holes 49, 49. As shown in Fig. 2, the bracket mounting holes 49, 49 are provided at the bent tip ends of the legs 48, 48. The bracket 41 is fixed to the roof reinforcement 14 with bolts and nuts, but the fixing method is not limited to this and the bracket 41 may be fixed with rivets or the like. The bracket 41 is made of metal, but is not limited to this and known materials such as resin (including fiber-reinforced resin) can be used.

[0019] The speaker 51 is inserted through the hole 22 in the headlining 21 and engaged with and held by the bracket 41. That is, when viewed from inside the vehicle cabin, the speaker 51 is positioned so that it is exposed to the interior of the vehicle cabin through the hole 22. The port 52 is provided on a side of the speaker 51 at a position closer to the exterior of the vehicle cabin than the headlining 21 (see FIG. 2). The port 52 faces in a direction along the exterior surface 21a of the headlining 21 around the hole 22 (see FIG. 1A). The port 52 is connected to an amplifier that drives the speaker 51. The speaker 51 may be fixed to fixing points 49a, 49a of the bracket 41 with bolts and nuts through mounting holes 53, 53. The shape of the speaker 51 is not limited to the above and can be selected arbitrarily from shapes in which the port 52 is positioned outside the vehicle cabin than the headlining 21 and faces in a direction along the exterior surface 21a of the headlining 21 around the hole 22.

[0020] The tip 32 of the harness 31 is inserted into the port 52 in a position substantially perpendicular to the side of the speaker 51 on which the port 52 is provided (see FIG. 1A ). That is, no bent connector or the like is connected to the tip 32. Therefore, the portion of the excess length 33 on the tip 32 side extends straight from the port 52 and is disposed so as to be along the exterior surface 21 a of the headlining 21. In other words, the portion of the excess length 33 on the tip 32 side is disposed at a position outside the headlining 21 in a position substantially parallel to the exterior surface 21 a of the headlining 21.

[0021] The excess length portion 33 may have a first portion 35, a bent portion 36, a second portion 37, and a third portion 38 (see FIG. 1B ). The first portion 35 protrudes outward from the first opening 45 and extends between the roof panel 11 and the headlining 21. The bent portion 36 bends in a U-shape at the tip of the first portion 35 and connects to the second portion 37. The second portion 37 extends from the bent portion 36 toward the first opening 45 and passes through the first opening 45 again. The third portion 38 curves from the tip of the second portion 37 toward the base end 34 and passes through the second opening 46. At least a portion of an outer circumferential surface 38 a of the third portion 38 abuts against an inner edge 46 a of the second opening 46. A portion of the portion extending from the second portion 37 to the third portion 38, facing the roof panel 11, is covered by the main body 42 of the bracket 41.

[0022] The speaker grill 61 is positioned closer to the interior of the vehicle than the speaker 51 and is secured to the bracket 41 (see FIG. 3A ). That is, the speaker 51 is housed between the bracket 41 and the speaker grill 61. The speaker grill 61 has locking clips 62, 62 provided at the front and rear, and locking pieces 63, 63 provided on the left and right. The speaker grill 61 is secured by inserting the locking clips 62, 62 and the locking pieces 63, 63 into the locking holes 49b, 49b and 49c, 49c provided on the bracket 41, respectively. The speaker grill 61 is larger than the hole 22 in the headlining 21 so that no gap is formed between the speaker grill 61 and the hole 22 after the locking. Note that the shape of the speaker grill 61 and the method of securing the speaker grill 61 to the bracket 41 are not limited to those described above. The speaker grill 61 is made of resin, but is not limited to this.

[0023] (Installation Process of Electrical Component) Next, with reference to FIGS. 4A to 4D , the installation process of the speaker 51, which is an electrical component according to the embodiment, will be described. First, the legs 48, 48 of the bracket 41 are fixed to the roof reinforcement 14 (see FIG. 4B ). Next, the headlining 21 is assembled to the roof panel 11 with the hole 22 of the headlining 21 aligned with the bracket 41 (see FIG. 4C ). The hole 22 is positioned so that the speaker 51, which is engaged and held by the bracket 41, can be inserted through the hole 22. A harness 31 with a base end 34 fixed thereto is placed on the headlining 21. At this time, the portion of the excess length 33 of the harness 31 that is located on the tip 32 side of the base end 34 is not fixed, and therefore can be routed in any direction (see FIG. 1B ). The headlining 21 is assembled to the roof panel 11, for example, by placing an adhesive surface on the headlining 21 and adhering it to the surface of the roof panel 11.

[0024] When assembling the headlining 21 to the roof panel 11, the excess length 33 of the harness 31 may be disposed between the edge of the second side wall 44 and the headlining 21. In this case, a guide portion 47, which is an inclined surface formed on the edge of the second side wall 44 on the inside of the passenger compartment, pushes the excess length 33 in a direction parallel to the outer surface 21a of the headlining 21 and away from the base end 34. This allows the excess length 33 to escape from between the edge of the second side wall 44 and the headlining 21.

[0025] Next, the portion of the excess length 33 extending from the base end 34 toward the tip end 32 is hung from the second opening 46 of the hole 22 toward the interior of the vehicle cabin (see FIG. 1B ). As illustrated in FIGS. 1A and 2 , an end 47a of the second side wall 44 on the second opening 46 side and toward the interior of the vehicle cabin extends toward the base end 34 of the excess length 33 along the periphery of the hole 22 in the headlining 21. This prevents the harness 31 from being bent and positioned between the second opening 46 and the base end 34 when the headlining 21 is assembled to the roof panel 11. If the harness 31 were bent in this position, the length of the harness 31 hanging toward the interior of the vehicle cabin from the hole 22 in the headlining 21 may be shortened. This may interfere with the operation of connecting the tip end 32 of the harness 31 to the port 52 of the speaker 51. It may also interfere with the operation of engaging the speaker 51 with the bracket 41.

[0026] Next, the tip 32 of the harness 31 is connected to the port 52 on the side of the speaker 51. Then, the speaker 51 is attached to the bracket 41 (see FIGS. 3B and 4C ). Along with the above operation, the excess length 33 is protruded outward from the first opening 45 of the bracket 41 and is tucked between the headlining 21 and the roof panel 11 and accommodated therein. At this time, the portion of the excess length 33 on the tip 32 side extends straight from the side surface where the port 52 is provided and is positioned along the cabin exterior surface 21 a of the headlining 21. That is, the portion of the excess length 33 on the tip 32 side is accommodated while protruding outward from the first opening 45 and is positioned along the cabin exterior surface 21 a of the headlining 21 in an orientation substantially parallel to the cabin exterior surface 21 a (see FIG. 1A ).

[0027] When excess length portion 33 is caused to protrude outward from first opening 45 of bracket 41, the portion of excess length portion 33 on the base end 34 side is restricted from moving outward by second side wall 44. As a result, the portion of excess length portion 33 on the base end 34 side is housed within second opening 46. Therefore, the portion of excess length portion 33 between the portion protruding outward from first opening 45 and the portion on the base end 34 side is bent in a U-shape, as illustrated in FIG. 1A (see FIG. 1A).

[0028] Next, the speaker grill 61 is fastened to the bracket 41. The fastening clips 62 of the speaker grill 61 are inserted into the fastening holes 49b of the bracket, and the fastening pieces 63 are inserted into the fastening holes 49c and fastened. As a result, the speaker 51 and the hole 22 of the headlining 21 are blocked by the speaker grill 61 (see FIGS. 2 and 4D). This completes the installation of the mounting structure for the speaker 51, which is an electrical component according to the embodiment.

[0029] (Operation and Effect) (1) The mounting structure for electrical components mounted on a vehicle according to the embodiment includes a roof panel 11 of the vehicle, a headlining 21 having a hole 22, a harness 31 routed between the roof panel 11 and the headlining 21, a bracket 41 fixed to the roof panel 11, and a speaker 51, which is an electrical component. The speaker 51 is engaged and held by the bracket 41 with at least a portion of the speaker 51 exposed to the interior of the vehicle cabin through the hole 22 in the headlining 21. The speaker 51 has a port 52, to which the harness 31 is connected, located on the outer side of the headlining 21. The port 52 is oriented in a direction along the outer surface 21 a of the headlining 21 around the hole 22. As a result, the harness 31 is disposed extending straight from the port 52 along the outer surface 21 a of the headlining 21. That is, the harness 31 is disposed along the exterior surface 21a of the headlining 21 and in a position substantially parallel to the exterior surface 21a. This prevents the slack harness 31 from sagging between the hole 22 of the headlining 21 and the speaker 51 when the speaker 51 is engaged with the bracket 41. This prevents the harness 31 from being pinched between the hole 22 of the headlining 21 and the speaker 51 when the speaker 51 is engaged with the bracket 41.

[0030] (2) According to the embodiment, the bracket 41 includes a main body 42 fixed to the roof panel 11, a first side wall 43 and a second side wall 44 extending from the main body 42 toward the interior of the vehicle cabin, and a first opening 45 defined by the main body 42, the first side wall 43, and the second side wall 44 and positioned to face the port 52. The harness 31 has an excess length 33 whose distal end 32 is connected to the port 52 and whose proximal end 34 is fixed to the headlining 21. The excess length 33 includes a first portion 35 extending from the port 52 to the outside of the first opening 45 and a second portion 37 passing through the first opening 45 on the proximal end 34 side of the first portion 35. That is, the first portion 35 extends straight from the port 52 along the exterior surface 21 a of the headlining 21. The first portion 35 protrudes through the first opening 45 from the port 52 side to the outside. The second portion 37 passes through the first opening 45 again and extends toward the base end 34. As a result, the position of the excess length 33 of the harness 31 that extends from the first portion 35 to the second portion 37 is determined by the first opening 45. This further stabilizes the posture of the harness 31 routed along the exterior surface 21a of the headlining 21. This further prevents the harness 31 from being pinched between the hole 22 of the headlining 21 and the speaker 51 when the speaker 51 is engaged with the bracket 41.

[0031] (3) Furthermore, according to the embodiment, the bracket 41 has a second opening 46 defined by the main body 42 and the second side wall 44 and positioned closer to the base end 34 of the excess length portion 33 than the first opening 45. The excess length portion 33 passes through the first opening 45 and the second opening 46. As a result, when the speaker 51 is engaged with the bracket 41, the excess length portion 33 is positioned between the first opening 45 and the second opening 46. Therefore, the position of the portion of the excess length portion 33 of the harness 31 that is closer to the base end 34 of the excess length portion 33 than the first opening 45 is determined by the second opening 46. This further stabilizes the posture of the harness 31 routed along the exterior surface 21a of the headlining 21. Therefore, when the speaker 51 is engaged with the bracket 41, it is possible to further prevent the harness 31 from being pinched between the hole 22 of the headlining 21 and the speaker 51.

[0032] (4) According to the embodiment, the excess length 33 further includes a third portion 38 that passes through the second opening 46 closer to the base end 34 than the second portion 37. At least a portion of the outer peripheral surface 38a of the third portion 38 abuts the inner edge of the second opening 46. Therefore, the position of the third portion 38 of the excess length 33 of the harness 31 that passes through the second opening 46 closer to the base end 34 than the second portion 37 is restricted by the second opening 46. This also restricts the positions of the second portion 37 and the first portion 35 that connect to the third portion 38. This further stabilizes the posture of the harness 31 routed along the exterior surface 21a of the headlining 21. This further prevents the harness 31 from being pinched between the hole 22 in the headlining 21 and the speaker 51 when the speaker 51 is engaged with the bracket 41. Furthermore, since the excess length portion 33 can be prevented from shifting in position due to vibration or impact, the excess length portion 33 can be prevented from being disposed in an unintended position and being pinched or tangled with surrounding components.

[0033] (5) Furthermore, according to the embodiment, the excess length portion 33 is covered by the bracket 41 on the side facing the roof panel 11 from the second portion 37 to the third portion 38. This prevents the harness 31 from swinging on the headlining 21 due to vibration or impact, and prevents the harness 31 from coming into contact with the roof panel 11.

[0034] (6) According to the embodiment, the cabin-side inner edge of the second side wall 44 is inclined so as to be positioned inward as it moves away from the port 52. When the headlining 21 is attached to the bracket 41 attached to the roof panel 11 from below, the excess length 33 of the harness 31 may be positioned between the second side wall 44 of the bracket 41 and the headlining 21. In this case, the guide portion 47, which is an inclined surface of the cabin-side inner edge of the second side wall 44, pushes the excess length 33 in a direction parallel to the cabin-exterior surface 21a of the headlining 21 and away from the base end 34. This allows the excess length 33 to escape from between the second side wall 44 and the headlining 21. Therefore, when attaching the headlining 21 to the roof panel 11, the harness 31 can be prevented from being pinched between the second side wall 44 and the headlining 21.

[0035] (7) Furthermore, according to the embodiment, the end 47a of the second side wall 44 on the second opening 46 side and on the cabin side extends toward the base end 34 of the excess length portion 33 along the periphery of the hole 22 in the headlining 21. Therefore, when assembling the headlining 21 to the roof panel 11, the harness 31 is prevented from being bent and disposed between the second opening 46 and the base end 34 of the excess length portion 33. This prevents the length of the harness 31 hanging from the hole 22 in the headlining 21 toward the cabin interior from becoming short. If the length of the harness 31 hanging from the hole 22 in the headlining 21 toward the cabin interior is short, it becomes difficult to connect the speaker 51 and the harness 31. Furthermore, when engaging the speaker 51 with the bracket 41, it becomes difficult to route the harness 31 along the cabin exterior surface 21a of the headlining 21. Therefore, by preventing the harness 31 from being bent and positioned between the second opening 46 and the base end 34 of the excess length portion 33, it is possible to prevent any problems from occurring in the connection operation between the speaker 51 and the harness 31 and the engagement operation of the speaker 51 to the bracket 41.

[0036] In the above embodiment, the mounting structure for the speakers 51 is provided on the left and right sides of the front and center of the roof panel 11, but this is not limiting and the speakers may be provided at any position on the roof panel 11. Also, in the above embodiment, the speaker 51 is used as an example of an electrical component, but it goes without saying that the present invention can also be applied when the electrical component is a light.

[0037] Although the embodiments of the present invention have been described above, the descriptions and drawings that form part of this disclosure should not be understood to limit the present invention. Various alternative embodiments, examples, and operating techniques will become apparent to those skilled in the art from this disclosure.
