Mode for Carrying Out the Invention

[0009] Embodiments of the present disclosure will be described with reference to the drawings. In the drawings referred to below, the same or corresponding members are denoted by the same reference numerals.

[0010] FIG. 1 is a perspective view schematically showing a fixing structure for in-vehicle equipment according to an embodiment of the present disclosure. This fixing structure 100 for in-vehicle equipment is preferably applied to a vehicle (such as a hybrid vehicle) including a battery pack 20 containing a plurality of storage cells.

[0011] As shown in FIG. 1, in a vehicle body 10, a housing portion 11 for housing a battery pack 20 and in-vehicle equipment 102 is formed. The battery pack 20 has a side surface 20a, and the housing portion 11 has an opposing wall 12 that faces the side surface 20a.

[0012] The battery pack 20 is fixed to the housing portion 11 via a mounting bracket 30 for mounting the battery pack 20 to the housing portion 11. The mounting bracket 30 is made of metal. The mounting bracket 30 is fixed to the battery pack 20 by a fastening member. As shown in FIGS. 1 and 2, one end of the mounting bracket 30 is fixed to the housing portion 11 by a bolt B20, and the other end of the mounting bracket 30 is fixed to the housing portion 11 by a bolt B30.

[0013] As shown in FIG. 1, a fixing structure 100 for in-vehicle equipment includes in-vehicle equipment 102, a first bracket 110, a second bracket 120, and a collar 130.

[0014] The in-vehicle equipment 102 is mounted on the vehicle. In the present embodiment, the in-vehicle equipment 102 is configured as a blower for cooling the battery pack 20. The in-vehicle equipment 102 is disposed between the side surface 20a of the battery pack 20 and the opposing wall 12.

[0015] The first bracket 110 is fixed to the in-vehicle equipment 102. As shown in FIGS. 1 and 3, the first bracket 110 has a first base portion 111 and at least one first fastening portion 112. In the present embodiment, as shown in FIGS. 1 and 2, at least one first fastening portion 112 includes a pair of first fastening portions 112.

[0016] The first base portion 111 is fixed to the outer peripheral surface of the in-vehicle equipment 102.

[0017] The first fastening part 112 is a part fastened to the first fastening surface provided on the vehicle. In this embodiment, the first fastening surface is constituted by the side surface 20a of the battery pack 20. The first fastening part 112 includes a first abutting surface 112S (see FIGS. 3 and 5) that abuts against the first fastening surface. The first abutting surface 112S is formed flat.

[0018] As shown in FIG. 4, a collar 130 made of metal is connected to the first fastening part 112. As shown in FIG. 5, the first fastening part 112 is fastened to the first fastening surface (side surface 20a) by inserting a bolt B1 into a reference hole 112h provided in the collar 130 and a screw hole 20h provided in the battery pack 20.

[0019] The second bracket 120 is fixed to the in-vehicle device 102. As shown in FIGS. 1 to 3, the second bracket 120 has a second base part 121 and a second fastening part 122.

[0020] The second base part 121 is fixed to the outer peripheral surface of the in-vehicle device 102. More specifically, the second base part 121 is fixed to a part of the outer peripheral surface of the in-vehicle device 102 that is separated from the part to which the first base part 111 is connected.

[0021] The second fastening part 122 has a shape extending from the second base part 121 in a direction intersecting the direction connecting the side surface 20a of the battery pack 20 and the opposing wall 12. The second fastening part 122 is a part fastened to the second fastening surface provided on the vehicle.

[0022] In this embodiment, the second fastening surface is formed on the mounting bracket 30. Specifically, the mounting bracket 30 has a fixing surface 30a fixed to the accommodating part 11 by a bolt B30 and an inclined surface 30b inclined with respect to the fixing surface 30a, and the inclined surface 30b constitutes the second fastening surface. The surface 11a of the accommodating part 11 to which the fixing surface 30a is fixed is set horizontally, for example.

[0023] As shown in FIG. 5, the angle θ2 formed between the second fastening surface (the inclined surface 30b) and the fixed surface 30a is set to an acute angle. This angle θ2 is set to be equal to or greater than the angle required for mounting the in-vehicle device 102 in plan view and equal to or less than the maximum bending angle.

[0024] The angle required for mounting the in-vehicle device 102 is set based on the molding of the in-vehicle device 102 and the following relational expression (1).

[0025] X × cos θ2 < ideal dimension in plan view ··· (1) (X is the design tolerance in plan view required for assembling the in-vehicle device 102)

[0026] The maximum bending angle is set based on the molding requirements and the gap between the mounting bracket 30 and the surrounding components.

[0027] As shown in FIGS. 3 and 5, the second fastening portion 122 includes a second contact surface 122S that contacts the second fastening surface. The second contact surface 122S is formed flat. As shown in FIG. 5, the angle θ1 formed between the first contact surface 112S and the second contact surface 122S is set to an obtuse angle. The second fastening portion 122 is fastened to the second fastening surface by a bolt B2 and a nut N2 that are fixed to the inclined surface 30b by welding. As shown in FIG. 5, a collar 130 made of metal is connected to the second fastening portion 122, and the collar 130 is provided with a through hole 122h that allows the insertion of the bolt B2 and can absorb the tolerance. Note that the second fastening portion 122 may be fastened to the second fastening surface by a bolt and a nut that are not welded to the inclined surface 30b.

[0028] As described above, in the fixed structure 100 of the in-vehicle device according to the present embodiment, since the angle θ1 formed between the first contact surface 112S of the first fastening portion 112 and the second contact surface 122S of the second fastening portion 122 is an obtuse angle, it is possible to reduce the outer shape in plan view of the structure including the in-vehicle device 102 and the brackets 110 and 120.
