[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a bracket mounting structure for an accessory according to the present invention will be described with reference to the drawings. 1 to 3 are diagrams showing an auxiliary equipment bracket mounting structure according to one embodiment of the present invention.

[0016] 1 to 3, the up, down, front, rear, left and right directions are defined as the front-to-rear direction of the vehicle based on the engine when placed on the vehicle, the side on which the accessories are placed is defined as the front, and the side opposite the accessories is defined as the rear.

[0017] The left-right direction of the vehicle (vehicle width direction) is defined as the left-right direction. The height direction of the engine is defined as the up-down direction, with the cylinder head cover side defined as the top and the oil pan side defined as the bottom.

[0018] First, the configuration will be described. As shown in FIG. 1, a vehicle is provided with an engine 1 as an internal combustion engine for a vehicle. The engine 1 includes a cylinder block 2, a cylinder head 3, a cylinder head cover 4, and an oil pan 5.

[0019] The cylinder block 2 is provided with a plurality of cylinders (not shown), and the cylinders are arranged side by side in the vehicle width direction of the engine 1. Each cylinder houses a piston (not shown), and the pistons are connected to a crankshaft (not shown) via a connecting rod (not shown).

[0020] The piston reciprocates within the cylinder, thereby rotating the crankshaft via the connecting rod.

[0021] The cylinder head 3 is attached to the upper part of the cylinder block 2, and is formed with a plurality of intake ports (not shown) and a plurality of exhaust ports (not shown).

[0022] The intake port and exhaust port are connected to the cylinders. The intake port introduces intake air into the cylinder, and the exhaust port discharges exhaust gas from the cylinder.

[0023] A chain case 6 is provided at the right end of the cylinder block 2 and the cylinder head 3, and covers a timing chain (not shown) from the right. The timing chain transmits the rotation of the crankshaft to an intake shaft and an exhaust shaft (not shown) that are provided in the cylinder head 3 and the cylinder head cover 4.

[0024] An alternator 7 constituting an accessory is attached to the chain case 6. The alternator 7 has an alternator body 8 and triangular first and second mounting portions 9 and 10 (see FIG. 3) that protrude outward from the alternator body 8.

[0025] The first mounting portion 9 protrudes diagonally downward and rearward from the alternator body 8, and is fastened to the chain case 6 by a bolt (not shown).

[0026] The second mounting portion 10 protrudes upward from the alternator body 8 and is attached to the chain case 6 by a first bracket 11 .

[0027] A second bracket 12 is attached to the second mounting portion 10, and a harness 13 is attached to the second bracket 12. One end of the harness 13 is connected to the alternator body 8, and the other end of the harness 13 is connected to a battery via another harness (not shown).

[0028] That is, the alternator body 8 is attached to the chain case 6 (engine 1) by a first attachment portion 9, a second attachment portion 10 and a first bracket 11, and a harness 13 is attached to the second bracket 12.

[0029] In this embodiment, the alternator body 8 constitutes an accessory body, and the second mounting portion 10 constitutes a mounting portion. The harness 13 constitutes an article for a vehicle.

[0030] As shown in FIG. 3, the second attachment portion 10 is provided with a first fastening portion 10A and a second fastening portion 10B.

[0031] The first fastening portion 10A is provided at the apex of a triangular second mounting portion 10 that protrudes outward from the alternator body 8, and is formed in a boss shape.

[0032] An alternator side fastening portion 11A of a first bracket 11 is fastened to the first fastening portion 10A by a bolt 20A (see FIG. 2).

[0033] 2, the first bracket 11 is formed in an S-shape when viewed from the right. An engine side fastening portion 11B is formed on the upper part of the alternator side fastening portion 11A, and the engine side fastening portion 11B is fastened to the chain case 6 by a bolt 20B.

[0034] A protruding portion 11C is formed on the upper portion of the first bracket 11, and the protruding portion 11C protrudes toward the side away from the engine 1 with respect to the engine side fastening portion 11B.

[0035] A protrusion 11D is formed on the lower part of the first bracket 11, and the protrusion 11D protrudes from the alternator side fastening part 11A toward the engine 1 side.

[0036] The second bracket 12 is fastened to the first fastening portion 10A by a bolt 20C, and the first bracket 11 and the second bracket 12 are fastened to a common second mounting portion 10 by bolts 20A and 20C, respectively.

[0037] The second mounting portion 10 is provided with a protrusion 10C, and the first bracket 11 and the second bracket 12 face each other with the protrusion 10C interposed therebetween.

[0038] Specifically, as shown in Figure 3, when an imaginary straight line 21 is set passing through the first fastening portion 10A and the second fastening portion 10B, the protrusion portion 10C is positioned above (outside) the imaginary straight line 21 and in a space 30 (see Figure 2) surrounded by the first bracket 11 and the second bracket 12.

[0039] In other words, when an imaginary straight line 21 is set passing through the bolt 20A fastened to the first fastening portion 10A and the bolt 20C fastened to the second fastening portion 10B, the protrusion portion 10C is positioned above (outside) the imaginary straight line 21 and in the space 30 (see Figure 2) surrounded by the first bracket 11 and the second bracket 12.

[0040] As shown in FIG. 2, the protrusion 10C has a rear end 10a located on the first bracket 11 side and a front end 10b located on the second bracket 12 side.

[0041] When a first imaginary plane 22 passing through the rear end 10a of the protrusion 10C and a second imaginary plane 23 passing through the front end 10b of the protrusion 10C and parallel to the first imaginary plane 22 are set, a portion of the first bracket 11 and a portion of the second bracket 12 extend into the space 31 between the first imaginary plane 22 and the second imaginary plane 23.

[0042] That is, a part of the first bracket 11 and a part of the second bracket 12 overlap with the protrusion 10C in the front-rear direction. The first imaginary plane 22 and the second imaginary plane 23 in this embodiment extend in the vertical direction, but may extend in the horizontal direction or an oblique direction.

[0043] In this embodiment, a rear end 10a of the protrusion 10C constitutes one end of the protrusion, and a front end 10b of the protrusion 10C constitutes the other end of the protrusion.

[0044] As shown in Figure 3, the second mounting portion 10 has a first connecting portion 10D located on one side of the triangle and connecting the first fastening portion 10A and the alternator body 8, and a second connecting portion 10E located on the other side of the triangle and connecting the first fastening portion 10A and the alternator body 8.

[0045] The second connecting portion 10E is formed to be shorter than the first connecting portion 10D, and the protruding portion 10C is adjacent to the first fastening portion 10A on the second connecting portion 10E side.

[0046] Specifically, the second fastening portion 10B and the protruding portion 10C are connected to the second connecting portion 10E, and the protruding portion 10C is provided on the first fastening portion 10A side with respect to the second fastening portion 10B.

[0047] A third connecting portion 10F is formed between the first connecting portion 10D and the second connecting portion 10E in the front-rear direction. The third connecting portion 10F connects the first fastening portion 10A and the alternator body 8.

[0048] The thickness of the third connecting portion 10F is formed to be thinner than the thicknesses of the first connecting portion 10D and the second connecting portion 10E, and the third connecting portion 10F is formed in a concave shape.

[0049] Next, the effects of the bracket mounting structure for the alternator 7 according to this embodiment will be described. The bracket mounting structure for the alternator 7 in this embodiment has a first bracket 11 for mounting the alternator 7 to the engine 1 and a second bracket 12 for mounting the harness 13 to the alternator 7, and the alternator 7 has a second mounting portion 10 for mounting the first bracket 11 and the second bracket 12.

[0050] This allows the first bracket 11 and the second bracket 12 to be disposed close to each other, thereby reducing the space required for disposing the first bracket 11 and the second bracket 12 compared to when the first bracket 11 and the second bracket 12 are disposed farther apart. As a result, the alternator 7 can be made smaller.

[0051] However, if the first bracket 11 and the second bracket 12 are positioned close to each other, when the alternator 7 is assembled to the engine 1, the first bracket 11 may swing about the bolt 20A as a fulcrum, and the second bracket 12 may swing about the bolt 20C as a fulcrum, which may cause interference between the first bracket 11 and the second bracket 12.

[0052] In addition, when the engine 1 is operating, vibrations from the alternator 7 may cause the first bracket 11 to swing about the bolt 20A as a fulcrum, and the second bracket 12 to swing about the bolt 20C as a fulcrum, which may result in interference between the first bracket 11 and the second bracket 12.

[0053] In the mounting structure of the alternator 7 of this embodiment, a protrusion 10C is provided on the second mounting portion 10, and the first bracket 11 and the second bracket 12 face each other with the protrusion 10C interposed therebetween.

[0054] As a result, when the first bracket 11 swings toward the second bracket 12, the first bracket 11 can be abutted against the protrusion portion 10C to prevent the first bracket 11 from rotating, and the first bracket 11 can be prevented from interfering with the second bracket 12.

[0055] In addition, when the second bracket 12 swings toward the first bracket 11, the second bracket 12 can be abutted against the protrusion portion 10C to prevent the second bracket 12 from rotating, and the second bracket 12 can be prevented from interfering with the first bracket 11.

[0056] Further, the first bracket 11 of this embodiment is formed in an S-shape when viewed from the front in FIG. 2, with the engine side fastening portion 11B located above the alternator side fastening portion 11A.

[0057] In addition, the protruding portion 11D is disposed so as to protrude from the alternator side fastening portion 11A toward the engine 1, and the protruding portion 11C is disposed so as to protrude toward the side away from the engine 1 with respect to the engine side fastening portion 11B.

[0058] In contrast, when the first bracket 11 is turned upside down and the engine side fastening portion 11B is positioned below the alternator side fastening portion 11A, the protruding portion 11C comes into contact with the protruding portion 10C.

[0059] Furthermore, when first bracket 11 is turned over and protruding portion 11D protrudes away from engine 1 relative to alternator side fastening portion 11A, protruding portion 11D comes into contact with protruding portion 10C.

[0060] This reliably prevents the first bracket 11 from being erroneously attached to the engine 1, and improves the efficiency of the work of assembling the alternator 7 to the engine 1.

[0061] Furthermore, according to the bracket mounting structure of the alternator 7 of this embodiment, the second mounting portion 10 has a first fastening portion 10A to which the first bracket 11 is fastened, and a second fastening portion 10B to which the second bracket 12 is fastened.

[0062] When an imaginary straight line 21 is set passing through the first fastening portion 10A and the second fastening portion 10B, the protrusion portion 10C is positioned above (outside) the imaginary straight line 21, in a space 30 surrounded by the first bracket 11 and the second bracket 12.

[0063] This allows the first bracket 11 to come into contact with the protrusion 10C when the first bracket 11 swings toward the second bracket 12, thereby preventing the first bracket 11 from rotating, and more effectively prevents the first bracket 11 from interfering with the second bracket 12.

[0064] In addition, when the second bracket 12 swings toward the first bracket 11, the second bracket 12 can be abutted against the protrusion portion 10C to prevent the second bracket 12 from rotating, thereby more effectively preventing the second bracket 12 from interfering with the first bracket 11.

[0065] Furthermore, according to the bracket mounting structure of the alternator 7 of this embodiment, the protrusion 10C has a rear end 10a located on the first bracket 11 side and a front end 10b located on the second bracket 12 side.

[0066] When a first imaginary plane 22 passing through the rear end 10a of the protrusion 10C and a second imaginary plane 23 passing through the front end 10b of the protrusion 10C and parallel to the first imaginary plane 22 are set, a part of the first bracket 11 and a part of the second bracket 12 extend into the space 31 between the first imaginary plane 22 and the second imaginary plane 23.

[0067] This allows the first bracket 11 and the second bracket 12 to be positioned closer to each other while preventing interference between them, and more effectively reduces the space required for placing the first bracket 11 and the second bracket 12.

[0068] Moreover, according to the bracket mounting structure of the alternator 7 of this embodiment, the alternator 7 has the alternator body 8, and the second mounting portion 10 is formed in a triangular shape that protrudes outward from the alternator body 8.

[0069] The first fastening portion 10A has a boss shape provided at an apex protruding outward from the alternator body 8, and the second mounting portion 10 has a first connecting portion 10D located on one side of the triangular second mounting portion 10 and connecting the first fastening portion 10A and the alternator body 8, and a second connecting portion 10E located on the other side of the triangular second mounting portion 10 and connecting the first fastening portion 10A and the alternator body 8.

[0070] The second connecting portion 10E is formed to be shorter than the first connecting portion 10D, and the protruding portion 10C is adjacent to the first fastening portion 10A on the second connecting portion 10E side.

[0071] This makes it possible to increase the rigidity of the second connecting portion 10E, which is shorter than the first connecting portion 10D, and also to increase the rigidity of the boss-shaped first fastening portion 10A.

[0072] In addition, by forming the protruding portion 10C near the second connecting portion 10E and the first fastening portion 10A, which have high rigidity, the rigidity of the protruding portion 10C can be increased.

[0073] Therefore, even if the first bracket 11 and the second bracket 12 collide with the protrusion 10C and an impact is applied to the protrusion 10C, damage to the protrusion 10C can be prevented. Therefore, interference between the first bracket 11 and the second bracket 12 can be more effectively prevented.

[0074] Moreover, according to the bracket mounting structure for alternator 7 of this embodiment, second fastening portion 10B is connected to second connecting portion 10E.

[0075] As a result, the rigidity of the second fastening portion 10B can be increased by the second connecting portion 10E having high rigidity, and the supporting rigidity of the harness 13 by the second fastening portion 10B can be increased.

[0076] Furthermore, according to the bracket mounting structure for the alternator 7 of this embodiment, the harness 13 is connected to the alternator 7 .

[0077] This makes it possible to prevent the harness 13 from being subjected to an excessive load due to vibrations of the engine 1 and the alternator 7.

[0078] Specifically, when one end of the harness 13 is attached to the alternator 7 and the other end of the harness 13 is supported on the engine 1 by another bracket, the harness 13 is connected to both the engine 1 and the alternator 7, which vibrate differently.

[0079] As a result, vibrations from the engine 1 and alternator 7 may cause one end of the harness 13 to move closer to or farther away from the other end, resulting in a large deformation of the harness 13 and possibly causing an excessive load to be applied to the harness 13.

[0080] In this embodiment, the harness 13 is supported by the second bracket 12 and the alternator 7, so that the amount of deformation of the harness 13 caused by vibrations of the engine 1 and the alternator 7 is prevented from becoming too great, and excessive load is prevented from being applied to the harness 13.

[0081] The auxiliary equipment may be an ISG (Integrated Starter Generator), an oil pump, a cooling water pump, an air compressor, etc.

[0082] Although an embodiment of the invention has been disclosed, it will be apparent to one skilled in the art that modifications may be made without departing from the spirit and scope of the invention, and all such modifications and equivalents are intended to be encompassed by the following claims.
