DESCRIPTION OF EMBODIMENTS

(4) Configuration of Shift Bracket

(5) With reference to the drawings, a description will hereinafter be made on a shift bracket 20 according to an embodiment. An arrow FR, an arrow UP, and an arrow RH illustrated in each of the drawings, which will be described below, respectively indicate a front direction (an advancing direction), an up direction, and a right direction of a vehicle. In addition, opposite directions of the arrows FR, UP, RH respectively indicate a rear direction, a down direction, and a left direction of the vehicle. In the case where a description will hereinafter be made by simply using the front-rear, right-left, and up-down directions, unless otherwise noted the front-rear, right-left, and up-down directions respectively indicate front and rear in a vehicle longitudinal direction, right and left in a vehicle lateral direction (a vehicle width direction), and up and down in a vehicle vertical direction.

(6) As illustrated in FIG. 1, the vehicle is provided with a floor tunnel 12 that is disposed at a center in the vehicle width direction, is projected upward in the vehicle vertical direction from a floor panel 11, and extends in the vehicle longitudinal direction. The floor tunnel 12 accommodates a power cable that couples an electric motor or a control unit disposed in a front compartment in a front portion of the vehicle and a battery disposed under a floor or in a rear portion of the vehicle, and the like.

(7) A cover panel 13 that covers the floor tunnel 12 from above is attached to an upper side of the floor tunnel 12. The cover panel 13 is a groove-shaped cross-section member that includes a top plate 14 and lateral plates 15 that are provided to be projected in the vehicle down direction from both sides in a width direction of the top plate 14, and is a vehicle frame member that extends in the vehicle longitudinal direction.

(8) The shift bracket 20 is coupled to an upper side of the top plate 14 in the cover panel 13. A shift lever unit 19 is attached to an upper surface of the shift bracket 20. The shift lever unit 19 includes: a shift lever 17 to be operated by an occupant; and a body 18 that detects a position of the shift lever 17 and transmits the position to a controller.

(9) The shift bracket 20 includes: a base plate 21 to which the shift lever unit 19 is attached; and a front leg portion 22 and a rear leg portion 23 as a plurality of leg portions that are coupled to the base plate 21 and the top plate 14 of the cover panel 13 and hold the base plate 21 with a space 30 being provided upward in the vehicle vertical direction from the top plate 14. The front leg portion 22 and the rear leg portion 23 are fixed onto the top plate 14 by bolts 24. A height of the base plate 21 can freely be adjusted by changing heights of the front leg portion 22 and the rear leg portion 23.

(10) As illustrated in FIG. 2, the base plate 21 is a groove-shaped cross-section member having a groove-shaped cross-section with a lower side opened in the vehicle vertical direction and having flanges 21f that are located on both sides in the vehicle width direction and extend in the vehicle longitudinal direction. The front leg portion 22 is also a groove-shaped cross-section member having a groove-shaped cross-section opened to the vehicle front side and having flanges 22f that are located on both sides in the vehicle width direction and extend in the vehicle vertical direction. A plate-shaped member 22p in a flat plate shape is provided between the flanges 22f on both of the sides of the front leg portion 22. The plate-shaped member 22p is disposed such that a surface thereof faces the vehicle longitudinal direction. A front end of each of the flanges 21f in the base plate 21 extends downward. Onto an inner surface in the vehicle width direction of this portion, an outer surface in the vehicle width direction of each of the flanges 22f at an upper end of the front leg portion 22 is superimposed and is coupled by spot welding, as indicated by a cross mark in FIG. 2.

(11) Each attachment portion 22b provided at a lower end of the front leg portion 22 has a U-shaped cross-section in which the flanges are raised on both sides of a bolt hole. The attachment portions 22b are fixed to the top plate 14 of the cover panel 13 by the bolts 24.

(12) As illustrated in FIG. 1, the rear leg portion 23 is a plate member that is folded to be projected upward in a U shape. An upper portion of the rear leg portion 23 is fixed to a lower surface of the base plate 21 by spot welding, and an attachment flange provided at each lower end is fixed to the top plate 14 of the cover panel 13 by the bolt 24.

(13) Electronic control units 31, 32, and 33 (hereinafter referred to as ECUs 31, 32, and 33) are disposed in the space 30 between the top plate 14 of the cover panel 13 and the base plate 21 of the shift bracket 20.

(14) The ECU 31 is fixed to a bracket 25, which is attached to the lower surface of the base plate 21, by a bolt. The ECU 32 is fixed to a vehicle rear side of the front leg portion 22 by an unillustrated bracket. The ECU 33 is fixed to the lower surface of the base plate 21.

(15) The front leg portion 22 is made from a material such as metal that can shield against electromagnetic waves, for example. In addition, in the front leg portion 22, a length of the plate-shaped member 22p in the vehicle width direction is equal to or greater than a length of each of the ECUs 31 to 33, which are illustrated in FIG. 1 and attached to the shift bracket 20, in the vehicle width direction.

(16) Operations and Effects of Shift Bracket

(17) In the shift bracket 20 according to the embodiment, which has been described so far, the base plate 21 is held with the space 30 being provided between the base plate 21 and the top plate 14 of the cover panel 13, and the shift lever unit 19 is attached onto the base plate 21. Thus, a height of the shift lever 17 can be set to a height that allows the occupant to easily use the shift lever 17. In addition, since the ECUs 31 to 33 can be disposed in the space 30 between the top plate 14 of the cover panel 13 and the base plate 21, a large number of the ECUs can be mounted. Furthermore, each of the ECUs 31 to 33 can be fixed to the cover panel 13 as the frame member via the shift bracket 20.

(18) Since the ECUs 31 to 33 are attached to the base plate 21, the front leg portion 22, or the rear leg portion 23, the shift bracket 20, to which the ECUs 31 to 33 are attached, can integrally be mounted on the top plate 14 of the cover panel 13. Thus, manufacturing man-hours can be reduced.

(19) Since the flanges 22f on both of the sides in the vehicle width direction of the front leg portion 22 are coupled to the flanges 21f on both of the sides in the vehicle width direction of the base plate 21, rigidity of the shift bracket 20 in the vehicle width direction can be increased. As a result, operability of the shift lever 17 during a lateral shift operation can be improved.

(20) In the shift bracket 20 according to the embodiment, a portion between the flanges 22f of the front leg portion 22 includes the plate-shaped member 22p, which includes a member made of a metal or other materials capable of shielding against electromagnetic waves, and the front leg portion 22 has a length in the vehicle width direction which is equal to or greater than the length of each of the ECUs 31 to 33 in the vehicle width direction. Accordingly, the plate-shaped member 22p of the front leg portion 22 functions as a shielding plate that shields against the electromagnetic waves, and thus can suppress an influence of the electromagnetic waves generated by each of the ECUs 31 to 33 on another electronic device disposed in the front portion of the vehicle.

(21) In the description that has been made so far, the rear leg portion 23 is the U-shaped folded plate member. However, the rear leg portion 23 is not limited thereto. Similar to the front leg portion 22, the rear leg portion 23 may include a groove-shaped cross-section member having a groove-shaped cross-section opened to the vehicle front side and having flanges that are located on both sides in the vehicle width direction and extend in the vehicle vertical direction. In such a case, it is possible to reduce the influence of the electromagnetic waves generated by each of the ECUs 31 to 33, which are mounted in front of the rear leg portion 23, on other electronic devices disposed in the rear portion of the vehicle. In addition, each of the front leg portion 22 and the rear leg portion 23 may have a groove-shaped cross-section opened to the vehicle rear side. Furthermore, both sides of the shift bracket 20 in the vehicle width direction may be covered with an electromagnetic shielding member, so as to further reduce the influence of the electromagnetic waves.
