JP 2001-260634 A

  The cockpit module assembly for a vehicle (cockpit module) described in Patent Document 1 is disposed so as to extend in the left-right direction of the vehicle inside an instrument panel (instrument panel), and both ends in the left-right direction of the vehicle are provided on the vehicle body. The instrument panel and its peripheral devices (blower unit, air conditioning unit, etc.) are integrated beforehand with the strength member (steering cross member) fixed to the side surface. Further, a vehicle steering device can be integrated. As described above, in the cockpit module, a plurality of in-vehicle components (instrument panel, blower unit, air conditioning unit, vehicle steering device, and the like) are fixed to the steering cross member, and the fixing positions thereof are various. When the cockpit module is mounted on the vehicle body side with both ends of the member fixed to the vehicle body side portion (side panel), the mass of the cockpit module may act as a torsional moment on the steering cross member. If the rigidity is improved by reinforcing the side panels to which both ends of the steering cross member are fixed in order to suppress the twisting of the steering cross member, the weight of the vehicle increases and the material cost increases accordingly. May be invited.

  Accordingly, an object of the present invention is to provide a cockpit module for a vehicle that can suppress twisting of a steering cross member due to the mass of the cockpit module.

In order to solve the above problems, a first aspect of the present invention is a vehicle in which a vehicle body-side floor panel below a vehicle compartment and left and right vehicle body-side side panels standing on both sides in the vehicle width direction of the floor panel are partitioned. A cockpit module for a vehicle fixed to a vehicle body in an integrated manner in a predetermined space in a front part of a room, comprising a steering cross member, a plurality of in-vehicle devices, and a center stay. The steering cross member extends in the vehicle width direction in the predetermined space in a mounted state in which both ends are fixed to the left and right side panels. The plurality of in-vehicle devices are respectively fixed to the steering cross member in a non-attached state before the steering cross member is fixed to the left and right side panels and integrated with the steering cross member, and the predetermined Each is stored in space. The center stay has a stay upper end fixed to the steering cross member in the non-attached state and a stay lower end fixed to the floor panel in the attached state. And supports the central portion in the vehicle width direction of the steering cross member from below. An imaginary plane including the center of gravity of the steering cross member perpendicular to the front-rear direction of the vehicle in the mounted state is included in a region behind the front end of the steering cross member and ahead of the rear end of the steering cross member. The center of gravity of the cockpit module is located in the area below the steering cross member in the mounted state.

  In the above configuration, the center of gravity of the cockpit module is disposed in a region near the virtual plane including the center of gravity of the steering cross member orthogonal to the front-rear direction of the vehicle in the mounted state. That is, in the mounted state, the position of the center of gravity of the cockpit module is disposed at substantially the same position in the front-rear direction as the position of the center of gravity of the steering cross member when viewed from the side of the vehicle, so that the mass of the cockpit module is twisted with respect to the steering cross member. Acting as a load can be suppressed. For this reason, when the cockpit module is in the mounted state, it is possible to suppress twisting of the steering cross member due to the mass of the cockpit module.

  In addition, since the position of the center of gravity of the cockpit module is located at substantially the same position in the front-rear direction as the position of the center of gravity of the steering cross member in a side view of the vehicle, for example, during assembly work of the vehicle, the steering of the cockpit module in an unmounted state is performed. When both ends of the cross member are supported and lifted by the arm or the like of the assembling robot, the cockpit module in the non-attached state holds substantially the same posture as the attached state. As described above, since the cockpit module in the non-attached state does not rotate around the steering cross member during the assembly work of the vehicle, the workability of the assembly work is improved.

  Further, since the twisting of the steering cross member can be suppressed, the rigidity of the vehicle body supporting both ends of the steering cross member can be suppressed, and the weight of the vehicle body is reduced and the material cost is reduced accordingly. be able to.

  In addition, since the center stay supports the central portion of the mounted steering cross member in the vehicle width direction from below, the support rigidity of the steering cross member can be ensured.

According to a second aspect of the present invention, there is provided the cockpit module according to the first aspect, wherein the center stay is vertically moved downward from one side in the front-rear direction from the upper end of the stay toward the lower end of the stay in the mounted state. a stay main body extending obliquely Te and organic and heavy parts which are fixed to the stay main body.

  In the above configuration, since the stay body of the center stay extends in the attached state from the upper end of the stay toward the lower end of the stay to one side in the front-rear direction with respect to the vertical direction, for example, in the side view of the vehicle, the cockpit When the position of the center of gravity of the cockpit module in a state where the center stay is removed from the module (hereinafter, referred to as a detached state) is on the other side in the front-rear direction (for example, forward) of the position of the center of gravity of the steering cross member. The stay body of the center stay can be inclined downward on one side (rear) in the front-rear direction from the upper end of the stay toward the lower end of the stay. When the stay body is inclined downward on one side in the front-rear direction from the upper end of the stay toward the lower end of the stay, the eccentric distance in the front-rear direction between the weight component and the center of gravity of the steering cross member in a side view of the vehicle is: The position of the heavy component becomes shorter as it is closer to the upper end of the stay, and becomes longer as it is closer to the lower end of the stay. For this reason, the position of the heavy parts can be adjusted according to the eccentric distance in the front-back direction between the center of gravity of the cockpit module in the unstayed state and the center of gravity of the steering cross member in a side view of the vehicle, and the center of gravity of the cockpit module can be easily adjusted. It can be arranged near the virtual plane.

The outlet of the duct communicates with a plurality of air conditioner vents 27 of the instrument panel 18.

  The blower of the air conditioning unit 15 introduces air from outside or inside the vehicle and blows it to the evaporator. As is well known, a low-pressure refrigerant (air conditioner gas) decompressed by a decompression device such as an expansion valve of a refrigeration cycle for vehicle air conditioning flows into the evaporator, and the low-pressure refrigerant absorbs heat from air flowing through an air passage and evaporates. This cools the air flowing from the blower. The heater uses the cooling water of the engine as a heat source to heat the air flowing from the evaporator. An air mix damper is provided between the evaporator and the heater core. By controlling the opening degree of the air mix damper, the amount of air passing through the heater core is adjusted, and the temperature of the air flowing into the passenger compartment 3 is reduced. Adjusted. In the air conditioning unit 15, during cooling operation, the air from the blower is cooled by heat exchange by an evaporator, and the amount of air passing through the heater core is restricted by the control of the air mix damper, so that the air at a low temperature is supplied to the passenger compartment. Spill into 3 Further, during the heating operation, the amount of air passing through the heater core is increased by the control of the air mix damper to heat the air, so that hotter air flows out into the passenger compartment 3 than during the cooling operation. .

  The fuse or relay block 16 is mounted on the steering cross member 11 in a non-attached state so that the fuse or relay block 16 is mounted on the steering cross member 11 on the passenger seat side from above when the state is changed from the unattached state to the attached state (not shown). Fixed through the like. The block 16 in the mounted state is fixed to the steering cross member 11 above the air conditioning unit 15 among the steering cross members 11. The mounted block 16 is located above the glove box 26 of the instrument panel 18. A fuse and a relay are detachably attached to the block 16.

  The various harnesses 17 are connected to the steering column 20, the air conditioning unit 15, the plurality of devices 29 of the instrument panel 18, and the plurality of electronic components 30 of the center stay 13, which will be described later, in a non-attached state. A connection portion such as a connector (not shown) is provided at the tip, and is attached to the steering cross member 11 in a non-attached state and is supported by the steering cross member 11. The connection portion such as a connector at the tip of the harness 17 is connected to a connection portion such as a connector (a mating side) of a connection destination in an attached state.

  As shown in FIGS. 2 and 3, the center stay 13 includes a pair of left and right stay legs (stay body) 31 and a plurality of (three in this embodiment) disposed between the left and right stay legs 31. And a plurality of electronic components (heavy components) 30 mounted on the shelf 32. The center stay 13 is mounted on the steering cross member 11 in the non-mounted state so as to extend obliquely downward and rearward from the center in the vehicle width direction of the steering cross member 11 in the vehicle width direction when the mounted state is changed from the non-mounted state. Is fixed via a bracket (not shown). The center stay 13 is fixed to the steering cross member 11 after fixing the other in-vehicle devices 12 of the plurality of in-vehicle devices 12 except for the instrument panel 18 to the steering cross member 11. The direction of the center stay 13 in the following description is the direction in the mounted state unless otherwise specified.

  As shown in FIG. 5, the left and right stay legs 31 of the center stay 13 are metal plates facing each other on both sides in the vehicle width direction of the vehicle 1, and a bracket (not shown) is provided on the steering cross member 11. It has a stay upper end 31a fixed to the floor panel 5 and a stay lower end 31b fixed to the floor panel 5, respectively. The stay lower end 31b is arranged rearward of the stay upper end 31a. That is, the left and right stay legs 31 extend obliquely downward from the steering cross member 11 rearward (one side in the front-rear direction) with respect to the vertical direction. The left and right stay legs 31 each have a bead 31c extending along the extending direction of the left and right stay legs 31 at a substantially central portion between the front edge and the rear edge. The bead 31c protrudes inward in the vehicle width direction. The left and right stay legs 31 in the mounted state support the central portion in the vehicle width direction of the steering cross member 11 from the floor panel 5 side obliquely below the rear of the steering cross member 11.

  The plurality of shelves 32 are metal plates extending in the vehicle width direction crossing the vertical direction in the mounted state, and are disposed between the left and right stay legs 31, and both ends in the vehicle width direction are provided. It is fastened and fixed to the left and right stay legs 31 by bolts or the like. The plurality of shelves 32 each have a mounting area 33 on the upper surface side on which the electronic component 30 can be mounted, are formed in substantially the same size, and are arranged at different positions in the front-rear direction. Specifically, of the three shelf portions 32, the middle shelf portion 32b is disposed rearward of the upper shelf portion 32a, and the lower shelf portion 32c of the middle shelf portion 32b is located lower than the middle shelf portion 32b. Is located rearward. That is, the mounting areas 33 of the plurality of shelf portions 32 are also arranged at different positions in the front-rear direction, and are arranged rearward toward the mounting area 33 of the lower shelf portion 32. As described above, the center stay 13 has the plurality of shelf portions 32 having different distances from the steering cross member 11 in the front-rear direction.

  The plurality of electronic components 30 are, for example, electronic control units (ECUs) that control various devices of the vehicle 1, each having a case 34 that accommodates a board or the like (not shown) therein, and a plurality of shelf boards. It is mounted on each mounting area 33 of the section 32 and fixed to the shelf 32. The plurality of electronic components 30 function as weight components for adjusting the position of the center of gravity g3 of the cockpit module 10 as described later. Note that the plurality of electronic components 30 are placed at predetermined placement positions obtained by experiments, simulations, and the like, in the placement areas 33 of the plurality of shelf boards 32.

  Next, the predetermined mounting positions of the plurality of electronic components 30 will be described with reference to FIG. In FIG. 6, g1 is the center of gravity of the steering cross member 11, and g2 is the center of gravity of the cockpit module 10 (excluding the center stay 13) in a state where the center stay 13 is removed from the cockpit module 10 (hereinafter, referred to as an unstay state). , G3 indicate the center of gravity of the cockpit module 10 (including the center stay 13).

  As shown in FIG. 6, the center of gravity g2 of the cockpit module 10 (excluding the center stay 13) in the unstayed state is strongly influenced by the air conditioning unit 15 which is a heavy object located below and in front of the steering cross member 11, and the steering cross member 11 is disposed below the front side (the other side in the front-rear direction). The center of gravity g3 of the cockpit module 10 (including the center stay 13) is lower than the steering cross member 11 in the mounted state, and includes a virtual plane 35 (including the center of gravity g1 of the steering cross member 11) perpendicular to the front-rear direction (FIG. 6). (Indicated by a two-dot chain line 35). As described above, the predetermined mounting position of the plurality of electronic components 30 (see FIG. 5) can be adjusted by attaching the center stay 13 to the cockpit module 10 in the unstayed state, so that the center of gravity g3 of the cockpit module 10 is removed. It is determined by an experiment, a simulation, or the like so that the cockpit module 10 in the stay state moves from the position of the center of gravity g2 and is arranged in a region near the virtual plane 35. The region near the imaginary plane 35 is a region near the imaginary plane 35 in the front-rear direction, for example, behind the front end of the steering cross member 11 and beyond the rear end of the steering cross member 11. This is an area including the front virtual plane 35. Further, the virtual plane 35 is a virtual plane obtained by extending the two-dot chain line 35 in the vehicle width direction, but is shown by the two-dot chain line 35 in FIG. 6 for convenience.

  In the cockpit module 10 configured as described above, the center of gravity g3 of the cockpit module 10 is below the steering cross member 11 in the mounted state, and includes the virtual plane 35 that includes the center of gravity g1 of the steering cross member 11 and is orthogonal to the front-rear direction. It is located in a nearby area. That is, in the mounted state, the position of the center of gravity g3 of the cockpit module 10 is arranged at substantially the same position in the front-rear direction as the position of the center of gravity g1 of the steering cross member 11 in a side view of the vehicle 1, so that the mass of the cockpit module 10 is reduced by the steering. Acting as a torsional load on the cross member 11 can be suppressed. For this reason, the twisting of the steering cross member 11 due to the mass of the cockpit module 10 can be suppressed in the mounted state.

  Further, since the position of the center of gravity g3 of the cockpit module 10 is disposed at substantially the same position in the front-rear direction as the position of the center of gravity g1 of the steering cross member 11 in a side view of the vehicle 1, for example, when the vehicle 1 is assembled, When both ends of the steering cross member 11 of the cockpit module 10 in the state are supported and lifted by the arm or the like of the assembling robot, the cockpit module 10 in the non-mounted state holds substantially the same posture as the mounted state. As described above, since the cockpit module 10 in the non-attached state does not rotate around the steering cross member 11 during the assembling work of the vehicle 1, the workability of the assembling work is improved.

  Further, since the twisting of the steering cross member 11 can be suppressed, the rigidity of the cab 2 (the side panel 7 and the like) supporting both ends of the steering cross member 11 can be suppressed, and the weight of the cab 2 can be reduced accordingly. And material cost can be reduced.

  Also, the left and right stay legs 31 of the center stay 13 in the mounted state support the central portion in the vehicle width direction of the steering cross member 11 from the floor panel 5 side obliquely below the steering cross member 11 behind the steering cross member 11. Support rigidity can be secured.

  Further, the center of gravity g2 of the cockpit module 10 (excluding the center stay 13) in the unstayed state is disposed below the front side (the other side in the front-rear direction) of the steering cross member 11, and the left and right stay legs of the center stay 13 are provided. 31 extends obliquely downward from the steering cross member 11 on the rear side (one side in the front-rear direction) with respect to the vertical direction. That is, the center stay 13 extends toward the steering cross member 11 in a direction opposite to the center of gravity g2 of the cockpit module 10 (excluding the center stay 13) in the non-stay state in the front-rear direction. Further, since the left and right stay legs 31 of the center stay 13 extend obliquely downward from the steering cross member 11 to the rear (one side in the front-rear direction) with respect to the vertical direction, the electronic components of the vehicle 1 in a side view are viewed. The eccentric distance in the front-rear direction between the component 30 and the center of gravity g1 of the steering cross member 11 becomes shorter as the mounting position of the electronic component 30 is closer to the upper end 31a of the stay, and becomes longer as the mounting position of the electronic component 30 is closer to the lower end 31b of the stay. For this reason, the position of the electronic component 30 can be adjusted according to the eccentric distance in the front-rear direction in the side view of the vehicle 1 between the center of gravity g2 of the cockpit module 10 and the center of gravity g1 of the steering cross member 11 in the unstayed state. The center of gravity g3 of the module 10 can be easily arranged near the virtual plane 35. For example, an electronic component 30 having a large mass out of the plurality of electronic components 30 may have a long eccentric distance in the front-rear direction in the side view of the vehicle 1 between the center of gravity g2 of the cockpit module 10 and the center of gravity g1 of the steering cross member 11 in the unstayed state. In this case, the center of gravity g2 of the cockpit module 10 and the center of gravity g1 of the steering cross member 11 are mounted on the mounting area 33 of the shelf 32 close to the lower end 31b of the stay in a side view of the vehicle 1. When the eccentric distance in the front-rear direction is short, it is placed on the placement area 33 of the shelf 32 close to the upper end 31a of the stay. In this manner, the center of gravity g3 of the cockpit module 10 can be easily arranged in the area near the virtual plane 35 depending on the mounting position of the electronic component 30.

  Therefore, according to the present embodiment, the twist of the steering cross member 11 due to the mass of the cockpit module 10 can be suppressed.

  In the present embodiment, the steering cross member 11 is a metal cylindrical rod-shaped member extending linearly, but is not limited to this. For example, a steering cross member having a bent portion or a steering cross member having a rectangular cross section may be used. Even in such a case, the center of gravity g3 of the cockpit module 10 is arranged in a region near the virtual plane orthogonal to the front-rear direction including the center of gravity g1 of the steering cross member in the mounted state. Further, the steering cross member 11 may be formed of a high-strength resin member or the like.

  Further, in the present embodiment, the center of gravity g2 of the cockpit module 10 (excluding the center stay 13) in the detached state is disposed below the front side (the other side in the front-rear direction) of the steering cross member 11, and the center stay 13 The left and right stay legs 31 extend obliquely downward from the steering cross member 11 toward the rear (one side in the front-rear direction) with respect to the vertical direction, but are not limited to this. For example, the center of gravity g2 of the cockpit module 10 in the unstayed state is disposed below the rear side (the other side in the front-rear direction) of the steering cross member 11 and the left and right stay legs 31 of the center stay 13 are connected to the steering cross member 11. From the front side (one side in the front-rear direction) and may extend obliquely downward with respect to the vertical direction.

  In this embodiment, a center stay 13 having a pair of left and right stay legs 31, a plurality of shelves 32, and a plurality of electronic components 30 is provided. The position of the center of gravity g3 can be adjusted, but is not limited to this. For example, a center stay composed of only one stay leg that supports the center portion of the steering cross member 11 in the vehicle width direction from below may be provided. By providing the center stay, the center of gravity of the cockpit module 10 is consequently provided. g3 may be arranged in a region near the virtual plane 35 orthogonal to the front-rear direction, including the center of gravity g1 of the steering cross member 11 in the mounted state.
