[0009] A mounting bracket according to one embodiment of the present invention is a mounting bracket that supports a power unit case member on a vehicle frame extending in a predetermined extension direction, comprising: a vehicle-side connecting portion supported by the vehicle frame; a case-side connecting portion which is formed to be larger in the extension direction than the vehicle-side connecting portion when viewed from above the vehicle body and is connected to the case member; and a fork portion which is formed to be larger in the extension direction than the vehicle-side connecting portion when viewed from above the vehicle body and is continuous with the vehicle-side connecting portion and the case-side connecting portion, wherein the case-side connecting portion has at least three bolt seating surfaces, each with a bolt hole formed therein, along the extension direction, and the fork portion is between adjacent bolt seating surfaces, along the extension direction of the bolt seating surfaces The mounting bracket is formed in a fork shape with vertical wall portions extending upward from the ends of the bolt seating surface and the end of the bolt seating surface on the vehicle body side connection portion, forming a space above the bolt seating surface. When the bolt seating surface located at one end in the extension direction is designated as the first bolt seating surface and the bolt seating surface adjacent to the first bolt seating surface is designated as the second bolt seating surface, the vertical wall portion has a notch portion cut out in the part located at one end of the first bolt seating surface in the extension direction, the height of the second bolt seating surface is made higher than the height of the first bolt seating surface, and the height of the vertical wall portion extending upward from both ends of the second bolt seating surface in the extension direction and the end of the second bolt seating surface on the vehicle body side connection portion is reduced by the amount by which the height of the second bolt seating surface has been increased. [Examples]

[0010] Hereinafter, a mounting bracket according to one embodiment of the present invention will be described with reference to the drawings. Figures 1 to 5 show a mounting bracket according to one embodiment of the present invention. In Figures 1 to 5, the up, down, front, rear, left, and right directions are defined as the front-rear direction of the vehicle, the left-right direction of the vehicle (vehicle width direction), and the up and down direction of the vehicle (vehicle height direction).

[0011] First, let's explain the configuration. In Figure 1, a vehicle body frame 2 is provided near the left end of the front of the vehicle 1, extending in a predetermined extension direction (front-to-back direction). An engine room 3 is formed to the right of the vehicle body frame 2.

[0012] The engine compartment 3 houses the power unit 4. The case member 4A of the power unit 4 is supported to the vehicle frame 2 by a mounting bracket 10. More specifically, a vehicle-side bracket 6 is fixed to the vehicle frame 2, and the mounting bracket 10 is supported to this vehicle-side bracket 6 via an elastic member (not shown).

[0013] As shown in Figures 2 to 5, the mounting bracket 10 comprises a vehicle body-side connecting portion 12, a case-side connecting portion 11, and a fork portion 13. The vehicle body-side connecting portion 12 is supported by the vehicle body frame 2 via the vehicle body-side bracket 6. The vehicle body-side connecting portion 12 extends in the vehicle width direction.

[0014] The case-side connecting portion 11 is connected to the case member 4A. The fork portion 13 is continuous with the vehicle body-side connecting portion 12 and the case-side connecting portion 11. As shown in Figure 5, the lower surface of the case-side connecting portion 11 is positioned below the lower surface of the vehicle body-side connecting portion 12 by a distance H. The case-side connecting portion 11 and the fork portion 13 are formed to be larger in the extension direction (front-rear direction) than the vehicle body-side connecting portion 12 when viewed from above the vehicle body.

[0015] The case-side connecting portion 11 has at least three first bolt seating surfaces 14, a second bolt seating surface 15, and a third bolt seating surface 16, each having bolt holes 14A, 15A, and 16A, along the extension direction.

[0016] The fork section 13 is formed in a three-pronged fork shape, having vertical wall sections 31 that form spaces 27, 28, and 29 above the first bolt seating surface 14, the second bolt seating surface 15, and the third bolt seating surface 16. The spaces 27, 28, and 29 constitute the fork sections of the three-pronged fork shape and are necessary spaces for bolts (not shown) and their fastening tools to pass through.

[0017] The vertical wall portion 31 extends upward from between the adjacent first bolt seating surfaces 14, second bolt seating surfaces 15, and third bolt seating surfaces 16, from the end portions in the extending direction of the first bolt seating surfaces 14, second bolt seating surfaces 15, and third bolt seating surfaces 16, and from the end portions on the vehicle body side connecting portion 12 side of the first bolt seating surfaces 14, second bolt seating surfaces 15, and third bolt seating surfaces 16.

[0018] Specifically, the vertical wall portion 31 has a plurality of fork tooth portions 20, 21, 22 and strip-shaped connecting walls 17, 18, 19. The fork tooth portion 20 extends upward from between the adjacent first bolt seating surface 14 and second bolt seating surface 15. The fork tooth portion 21 extends upward from between the adjacent second bolt seating surface 15 and third bolt seating surface 16. The fork tooth portion 22 extends upward from the end portion (front end portion) in the extending direction of the third bolt seating surface 16.

[0019] The first bolt seating surface 14 is located at one end portion (rear end portion) in the extending direction, and the second bolt seating surface 15 is adjacent to the first bolt seating surface 14.

[0020] On one side (rearward) in the extending direction of the first bolt seating surface 14, peripheral components 5 such as sensors are arranged close to the vertical wall portion 31.

[0021] Here, since the peripheral components 5 are arranged close to the vertical wall portion 31, the vertical wall portion 31 may interfere with the peripheral components 5 when the peripheral components 5 are attached and detached or the like. Also, when a rearward load F (see FIG. 2) acts on the mount bracket 10 due to a collision of the vehicle 1 and the vertical wall portion 31 is displaced rearward, the vertical wall portion 31 may contact the peripheral components 5.

[0022] To avoid interference with the peripheral components 5, the vertical wall portion 31 has a notch portion 25 in which the portion located at one end portion in the extending direction of the first bolt seating surface 14 is cut out. As shown by the broken line, the notch portion 25 is formed by cutting out the fork tooth portion at one end portion in the extending direction. That is, the fork tooth portion cut out as the notch portion 25 was a portion that extended upward from the end portion (rear end portion) in the extending direction of the first bolt seating surface 14 before being cut out.

[0023] By providing a notch 25 in the vertical wall portion 31 of the mounting bracket 10, interference with surrounding parts 5 can be avoided. However, even with the notch 25 in place, it becomes necessary to maintain the strength of the vertical wall portion 31. In other words, the reduction in rigidity due to the provision of the notch 25 in the vertical wall portion 31 must be compensated for by improving the rigidity of the remaining portion of the vertical wall portion 31.

[0024] Therefore, in this embodiment, the height of the second bolt seating surface 15 is made higher than the height of the first bolt seating surface 14, and the height of both ends of the second bolt seating surface 15 in the extending direction on the vertical wall portion 31 and the portion of the bolt seating surface 15 extending upward from the end on the vehicle body side connecting portion 12 are lowered by the amount by which the height of the second bolt seating surface 15 has been increased. Here, the height of each bolt seating surface is the height from the lower surface of the case side connecting portion 11 to its bolt seating surface.

[0025] As shown in Figure 4, when the height of the first bolt seating surface 14 is H1, the height of the second bolt seating surface 15 is H2, and the height of the third bolt seating surface 16 is H3, the height of the second bolt seating surface 15 (H2) is made higher than the height of the first bolt seating surface 14 (H1). In addition, the height of both ends of the second bolt seating surface 15 in the extension direction in the vertical wall portion 31 and the portion extending upward from the end of the bolt seating surface 15 on the vehicle body side connecting portion 12 are made lower by the amount that the height of the second bolt seating surface 15 is increased.

[0026] In other words, the height of the fork teeth 20, 21 and the connecting wall 18 in the vertical wall 31 is lowered by the same amount as the height of the second bolt seating surface 15 being increased. In this embodiment, the height of the fork teeth 20, 21 and the connecting wall 18 is set to H4. The height of the fork teeth 22 and the connecting wall 19 is set to H5. That is, if the notch 25 is not provided, the height of the second bolt seating surface 15 is the same as H1 or H3, but in order to offset the decrease in rigidity of the connecting wall 19 due to the provision of the notch 25, the height of the second bolt seating surface 15 adjacent to the notch 25 is increased to H2, and the fork teeth 20, 21 extending from the second bolt seating surface 15 are shortened by the same amount.

[0027] The connecting wall 17 extends upward from the end (left end) of the first bolt seating surface 14 on the vehicle body side connecting portion 12 and is continuous with the adjacent fork teeth.

[0028] The connecting wall 18 extends upward from the end (left end) of the second bolt seating surface 15 on the vehicle body side connecting portion 12 and is continuous with the adjacent fork teeth.

[0029] The connecting wall 19 extends upward from the end (left end) of the third bolt seating surface 16 on the vehicle body side connecting portion 12 and is continuous with the adjacent fork teeth.

[0030] The connecting wall 17 has an opening 30 between it and the first bolt seating surface 14. The connecting wall 18 has an opening 23 between it and the second bolt seating surface 15. The connecting wall 19 has an opening 24 between it and the third bolt seating surface 16. These openings 30, 23, and 24 are provided at the lower ends of the connecting walls 17, 18, and 19.

[0031] As described above, in this embodiment, the mount bracket 10 includes a vehicle body side connecting portion 12 supported by the vehicle body frame 2, a case side connecting portion 11 which is formed to be larger in the extension direction than the vehicle body side connecting portion 12 when viewed from above the vehicle body and is connected to the case member 4A, and a fork portion 13 which is formed to be larger in the extension direction than the vehicle body side connecting portion 12 when viewed from above the vehicle body and is continuous with the vehicle body side connecting portion 12 and the case side connecting portion 11. The case side connecting portion 11 has at least three first bolt seating surfaces 14, a second bolt seating surface 15, and a third bolt seating surface 16 along the extension direction, each having bolt holes 14A, 15A, and 16A formed therein.

[0032] The fork section 13 is formed in a fork shape, having vertical wall sections 31 that extend upward from the space between adjacent first bolt seating surfaces 14, second bolt seating surface 15, and third bolt seating surface 16, from the extensional ends of the first bolt seating surfaces 14, second bolt seating surface 15, and third bolt seating surface 16, and from the ends of the first bolt seating surfaces 14, second bolt seating surface 15, and third bolt seating surface 16 on the vehicle body side connecting section 12, forming spaces 27, 28, and 29 above the bolt seating surfaces 14, 15, and 16. On one side in the extensional direction of the first bolt seating surface 14, peripheral components 5 are arranged close to the vertical wall section 31.

[0033] Furthermore, the vertical wall portion 31 has a notch 25 in which a portion located at one end of the first bolt seating surface 14 in the extending direction is cut out. In addition, the height of the second bolt seating surface 15 is made higher than the height of the first bolt seating surface 14, and the height of both ends of the second bolt seating surface 15 in the extending direction and the portion extending upward from the end of the second bolt seating surface 15 on the vehicle body side connecting portion 12 in the vertical wall portion 31 are made lower by the amount by which the height of the second bolt seating surface 15 has been increased.

[0034] This prevents the vertical wall portion 31 from interfering with the surrounding parts 5 by providing a notch 25 at one end of the vertical wall portion 31. Furthermore, it prevents the vertical wall portion 31 from coming into contact with the surrounding parts 5 if the mount bracket 10 is deformed due to a collision with the vehicle 1.

[0035] Furthermore, by making the height of the second bolt seating surface 15 higher than the height of the first bolt seating surface 14, the height of the vertical wall portion 31 extending upward from the second bolt seating surface 15 is reduced, and the rigidity of the vertical wall portion 31 extending upward from the second bolt seating surface 15 can be improved, thereby improving the rigidity of the fork portion 13. This makes it possible to suppress deformation of the fork portion 13 of the mount bracket 10 due to collision with the vehicle 1.

[0036] Furthermore, since the rigidity of the fork section 13 can be improved without increasing the height of the first bolt seating surface 14, etc., the mounting bracket 10 can be made lighter compared to the case where the heights of the first bolt seating surface 14, the second bolt seating surface 15, and the third bolt seating surface 16 are all increased.

[0037] As a result, rigidity can be ensured even when a notch 25 is provided in the mounting bracket 10 to avoid interference with surrounding parts 5.

[0038] In this embodiment, the vertical wall portion 31 has multiple fork teeth 20, 21, 22 extending upward from the extensional ends of the first bolt seating surfaces 14, second bolt seating surfaces 15, and third bolt seating surfaces 16, and between adjacent first bolt seating surfaces 14, second bolt seating surfaces 15, and third bolt seating surfaces 16, as well as strip-shaped connecting walls 17, 18, 19 extending upward from the vehicle body side connecting portion 12 end of the first bolt seating surfaces 14, second bolt seating surfaces 15, and third bolt seating surfaces 16 and continuous with adjacent fork teeth. The notch portion 25 is formed by cutting out a fork tooth portion at one end in the extensional direction.

[0039] As a result, by cutting out the fork teeth at one end in the extension direction, a notch 25 is formed, which allows the mount bracket 10 to have a shape that is advantageous in avoiding interference with surrounding parts 5.

[0040] In this embodiment, the connecting walls 17, 18, and 19 have openings 30, 23, and 24 between them and the first bolt seating surface 14, the second bolt seating surface 15, and the third bolt seating surface 16.

[0041] This allows the mounting bracket 10 to be made lighter by forming openings 30, 23, and 24.

[0042] While embodiments of the present invention have been disclosed, it will be apparent to those skilled in the art that modifications can be made without departing from the scope of the invention. All such modifications and equivalents are intended to be included in the following claims. [Explanation of Symbols]
