Description

  The present invention relates to an in-vehicle component mounting structure and an assembling method for an in-vehicle component, and more particularly to an in-vehicle component mounting structure for an automobile in which an in-vehicle component such as an electronic control unit is mounted on the front surface of a dash panel and an in-vehicle component mounting method.

2. Description of the Related Art Conventionally, it is known that an on-vehicle component, for example, an electronic control unit such as an ECU (Engine Control Unit) is attached to a dash panel that partitions a vehicle compartment and an engine room.
For example, Patent Document 1 below discloses a structure in which a metal control unit (ABS unit) is mounted in the vicinity of a FE filter on the front surface of a dash panel in consideration of safety at the time of a vehicle collision.

  In this way, by mounting the control unit on the front surface of the dash panel, the vehicle-mounted components can be efficiently installed in the engine room by effectively using the space behind the power train such as the engine.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a front perspective view of the front part of the vehicle in the engine room employing the first embodiment of the present invention, FIG. 2 is a perspective view of the main part from above the engine room, and FIG. 3 is an ECU (engine control unit) set FIG. 4 is a perspective view of a single part of the mounting bracket of the ECU.

  As shown in FIG. 1, the vehicle body structure constituting the engine room E in the front part of the vehicle has a pair of left and right front side frames 1, 1 extending in the vehicle front-rear direction and a rear end part of the front side frames 1, 1. Panel 2 extending in the vehicle width direction and partitioning engine room E and vehicle compartment C, cowl box 3 extending in the vehicle width direction above dash panel 2, and vehicle width direction of front side frames 1 and 1 A wheel house 4 that bulges inward in the engine room E on the outer side and a suspension tower 5 that extends in the vertical direction at the center position of the wheel house 4 are provided.

  In the engine room E, a transmission M is mounted on the inner side of the right front side frame 1. Although not shown in detail, the transmission M is a so-called horizontal type transmission M in which an input / output shaft is installed so as to extend in the vehicle width direction.

  A disc drum-shaped master back device 6 is attached to the front surface of the dash panel 2 on the vehicle rear side of the transmission M. As is well known, the master back device 6 is a booster device for a brake device and has a relatively large volume.

  An ECU 7 that performs engine control and the like is installed diagonally forward of the master back device 6. The ECU 7 is a box-shaped structure that is elongated in the vertical direction, and houses a control board (not shown) for controlling the engine and the like.

  A harness 10 that extends to the vehicle front side and bends from the middle to the rear side is connected to the side surface portion of the ECU 7 in the vehicle width direction. This harness 10 is configured such that its tip end portion is branched into three parts 10a, 10b, 10c and connected to the ECU 7, and the rear part thereof is integrated into one through hole 8 of the dash panel 2. It is configured to route to the passenger compartment C side through.

Detailed structures of the harness 10 and the ECU 7 will be described with reference to FIG.
The ECU 7 is installed with the vehicle width direction inner side (the left side in the drawing) tilted so as to be positioned forward of the vehicle width direction outer side in plan view so as to avoid the master back device 6 as described above. Yes. This installation position is defined by a mounting bracket 20 provided between the dash panel 2 and the installation position. That is, the mounting bracket 20 has three legs 20A, 20B, and 20C (see FIG. 4) extending in the front-rear direction, as will be described later, and thus the ECU 7 is positioned away from the dash panel 2 forward. And can be positioned in front of the master back device 6.

  The ECU 7 is configured to be fastened and fixed to the mounting bracket 20 at a total of four locations, two at the upper portion and two at the lower portion, and among these, one side portion of the ECU 7 ( The front part is fastened and fixed to the first flange part 21 and the second flange part 22 of the mounting bracket 20 by the first fastener 31 and the other side part (rear part) of the ECU 7 by the second fastener 32, respectively. It is configured as follows.

Further, in order to connect the harness 10 as described above, the ECU 7 is formed with the socket 71 connected to the coupler 11 provided at the tip of the harness 10 on the inner side surface 7a in the vehicle width direction. The socket 71 is formed in a rectangular tube shape, and is configured so that three are arranged vertically corresponding to the coupler 11 of the branched harness 10.
On the other hand, the brake fluid tank 61 of the master back device 6 is disposed above the socket 71. The brake fluid tank 61 is formed so as to largely protrude toward the front side of the vehicle in order to avoid the cowl box 3 positioned above, and the socket 71 of the ECU 7 is connected to the dash panel 2 in a state where the ECU 7 is assembled to the dash panel 2. It is installed at a position that covers from above.

  Since the brake fluid tank 6 is installed at such a position, it becomes difficult to insert the coupler 11 of the harness 10 into the socket 71 of the ECU 7 after the ECU 7 is assembled to the dash panel 2, and the wiring work is difficult. become. In particular, when performing a locking operation of a harness locking mechanism 80 (see FIG. 3), which will be described later, at the time of wire connection work, the operator cannot visually observe the harness locking mechanism 80, and thus the locking operation cannot be performed. Arise.

Therefore, in the present embodiment, as shown in FIG. 3, once the mounting bracket 20 to which the ECU 7 is attached is assembled to the dash panel 2, only the ECU 7 can be swung outwardly from the vehicle. .
That is, by configuring the upper part of the ECU 7 so that it can be swung outwardly without attaching the upper part of the ECU 7 to the mounting bracket 20, the socket 71 portion of the ECU 7 is temporarily moved in the vehicle width direction during assembly work. It is moved outward and positioned at a position not covered by the brake fluid tank 61.

  Thus, the operator can insert the coupler 11 of the harness 10 into the socket 71 and lock the harness lock mechanism 80 while visually observing the socket 71 portion of the ECU 7, and perform the connection work between the ECU 7 and the harness 10. Can do.

  The detailed structure of the mounting bracket 20 will be described with reference to FIG. The mounting bracket 20 includes a substantially rectangular plate-like main body portion 25 located on the rear side of the ECU 7, a first leg portion 20 </ b> A extending rearward at the upper center of the main body portion 25, and one side portion of the main body portion 25 ( A second leg portion 20B extending rearward at the front portion and a third leg portion 20C extending rearward at the other side portion (rear portion) of the main body portion 25 are provided.

  The main body portion 25 is provided with a first flange portion 21 and a second flange portion 22 for fastening and fixing the upper portion of the ECU 7 at the upper portion, and a third flange portion 23 for fastening and fixing the lower portion of the ECU 7 at the lower portion, Four flange portions 24 are provided.

  The first flange portion 21 is bent forward so as to be substantially perpendicular to the main body portion 25, and the second flange portion 22 is formed to extend upward from the main body portion 25 as it is. The first flange portion 21 is formed with a notch groove 26 that extends in the lateral direction to allow the first fastener 31 to be slid into the first flange portion 21. On the other hand, a fastening hole 27 for fastening and fixing the second fastener 32 is formed in the second flange portion 22.

  The third flange portion 23 and the fourth flange portion 24 are both bent in a vertical wall shape so as to be substantially perpendicular to the main body portion 25, and the lower portion of the ECU 7 is connected to the third flange portion 23 and the fourth flange portion. 24.

  Further, the third flange portion 23 and the fourth flange portion 24 are formed with rotation holes 28 and 29, respectively, and a third fastener 33 extending in the lateral direction through which the rotation holes 28 and 29 are inserted. The lower part of the ECU 7 is fastened and fixed by the fourth fastener 34.

  In this embodiment, the third fastening tool 33 and the fourth fastening tool 34 are set so as to be located on the same line, thereby constituting the swing shaft L1 of the ECU 7 extending in the substantially front-rear direction. Thus, with the ECU 7 mounted on the mounting bracket 20, the ECU 7 can be swung outwardly in the vehicle width direction around the swing axis L1, as shown by the broken line.

  By configuring the mounting bracket 20 in this way, as described above, the ECU 7 is swung outward in the vehicle width direction during the assembly work of the ECU 7, and the coupler 11 of the harness 10 (see FIG. 3). Can be inserted into the socket 71 of the ECU 7 (see FIG. 3).

  The harness lock mechanism will be described with reference to FIGS. FIG. 5 is an overall schematic diagram of the harness locking mechanism, and FIG. 6 is a schematic diagram for explaining the locking operation of the harness locking mechanism, where (a) shows the first stage and (b) shows the second stage.

The harness lock mechanism 80 includes a lock lever 81 provided in the coupler 11 and a locking groove 82 provided in the socket 71.
First, the lock lever 81 is pivotally supported on the side surface of the coupler 11 via a rotation fulcrum 83, provided with an engagement hook 84 at one end and a pressing operation portion 85 at the other end. Further, one end portion 86 around the engaging hook 84 is formed so as to be positioned one step lower than the other portions on the coupler 11 side.

  On the other hand, the locking groove 82 of the socket 71 is formed in a substantially concave shape at the side end 87a of the step portion 87, which is formed one step higher than the wall portion 71a of the socket 71. Further, the wall portion 71 a of the socket 71 is set to be positioned slightly above the side surface of the coupler 11.

  As is well known, a plurality of connection terminals (not shown) that are electrically connected to a connection terminal (not shown) on the coupler 11 side are provided inside the socket 71, The ECU 7 communicates with a control board (not shown) inside the ECU 7 so that the other on-vehicle equipment and the ECU 7 exchange electric signals and the like.

  The harness lock mechanism 80 thus configured locks this connection state by inserting the coupler 11 into the socket 71 of the ECU 7 as shown by an arrow and then performing a lock operation.

Next, the lock operation of the harness lock mechanism 80 will be described with reference to FIG.
First, in the first stage (unlocked state) of (a), the lock lever 81 is located on the opposite side to the position of the harness 10, and the coupler 11 is inserted into the socket 71 at the position of the lock lever 81.

  In this inserted state, the one end portion 86 of the lock lever 81 that is lowered by one step rides on the wall portion 71a of the socket 71. In this state, the pressing operation portion 85 of the lock lever 81 is pressed to move the lock lever 81 to the arrow. Rotate in the direction.

Next, as shown in the second stage (locked state) of (b), the lock lever 81 is rotated until the engagement hook 84 of the lock lever 81 engages with the locking groove 82 of the socket 71. Thereby, the lock lever 81 is engaged with the socket 71, and the connection state between the harness 10 and the socket 71 is locked.
The lock position of the lock lever 81 is maintained by holding the one end portion 86 of the lock lever 81 on the wall portion 71a of the socket 71 with a biasing force. By maintaining the position of the lock lever 81, the engagement relationship between the engagement hook 84 of the lock lever 81 and the engagement groove 82 of the socket 71 is maintained, and the harness lock mechanism 80 is completely locked.

  Thus, by locking the harness lock mechanism 80, the connection state of the coupler 11 of the harness 10 and the socket 71 of the ECU 7 can be completely locked, and a disturbance acts on the harness 10 while the vehicle is running. Even if a load acts in the pulling direction, the connection state between the coupler 11 and the socket 71 will not be lost, and problems such as disconnection of the coupler 11 can be solved.

  Of course, as shown in this schematic diagram, the position of the lock lever 81 can only be positioned on the opposite side of the position of the harness 10 from the structural viewpoint, so that the harness 10 faces the vehicle front side as in this embodiment. When routing, the lock lever 81 is inevitably positioned on the vehicle rear side of the socket 71, and the lock operation has to be difficult.

  As shown in this schematic diagram, the harness lock mechanism 80 is configured such that the position of the lock lever 81 is different between the locked state (b) and the unlocked state (a). For this reason, the operator can confirm the locked state and unlocked state of the harness lock mechanism 80 at a glance by visually observing the position of the lock lever 81.

  Next, an assembling method of the ECU 7 to the dash panel 2 will be described using a flowchart shown in FIG.

  First, in S <b> 1, the ECU 7 is attached to the attachment bracket 20 in advance before being assembled to the dash panel 2. Specifically, the lower portion of the ECU 7 is attached to the third flange portion 23 and the fourth flange portion 24 of the mounting bracket 20 via the third fastener 33 and the fourth fastener 34. At this time, the third fastener 33 and the fourth fastener 34 are gently tightened so that the ECU 7 itself swings with respect to the mounting bracket 20. Note that the ECU 7 may be attached to the mounting bracket 20 with caulking pins instead of the third fasteners 33 and the fourth fasteners 34.

  Next, the mounting bracket 20 is fastened and fixed to the dash panel 2 at S2. This fastening and fixing is performed by using mounting bolts 20Aa, 20Ba, and 20Ca (see FIG. 4) provided at the tips of the first to third leg portions 20A, 20B, and 20C described above using stud bolts and nuts (not shown). This is done by fastening to the dash panel 2.

  Next, in S3, the ECU 7 is swung outward in the vehicle width direction. Specifically, the upper part of the ECU 7 is moved so as to be slightly inclined outward in the vehicle width direction, and the ECU 7 is inclined (see FIG. 2).

  Next, the harness 10 is connected to the ECU 7 in S4. In this connection work, the coupler 11 of the harness 10 is inserted into the socket 71 of the ECU 7 and the harness lock mechanism 80 is locked.

  Thereafter, in S5, the ECU 7 is returned to the original position. Specifically, the upper portion of the ECU 7 is swung inward in the vehicle width direction, and the ECU 7 is returned to the mounting bracket 20 side. At this time, if the first fastener 31 temporarily fastened to the ECU 7 is slidably engaged with the notch groove 26 of the first flange portion 21, the positional relationship between the mounting bracket 20 and the ECU 7 can be reliably defined.

  Finally, the ECU 7 is finally fixed to the mounting bracket 20 in S6. Specifically, the upper part of the ECU 7 is fixed to the mounting bracket 20 via the first fastener 31 and the second fastener 32. As described above, if the position of the ECU 7 is defined using the notch groove 26 and the first fastener 31, even if this fixing operation is performed in a deep position in the engine room E, the operation can be performed relatively easily. It can be carried out.

  By taking the above assembling method, the operator can easily and surely perform the connection work of the ECU 7 and the harness 10 while visually observing.

Next, the function and effect of the present embodiment configured as described above will be described in detail.
In this embodiment, only the ECU 7 is configured to be swingable outward in the vehicle width direction with the mounting bracket 20 attached to the dash panel 2.
Thereby, the socket 71 of ECU7 can be moved to the vehicle width direction outer side, and the harness 10 can be connected on the vehicle width direction outer side in this state.
For this reason, the operator can easily perform the wiring work of the harness 10 while visually observing.
Therefore, in the in-vehicle component mounting structure of the automobile in which the ECU 7 is attached to the dash panel 2, it is possible to avoid interference with other in-vehicle devices as much as possible and to install the ECU 7 efficiently in the engine room E, but at a high cost. Thus, the wiring work of the harness 10 of the ECU 7 can be easily performed.

In this embodiment, at least two flanges of the third flange portion 23 and the fourth flange portion 24, the third fastener 33, and the fourth fastener 34 constitute the swing shaft L1 of the ECU 7. .
Thus, the ECU 7 can be swung without increasing the number of parts separately.
Therefore, the connection work between the ECU 7 and the harness 10 can be easily performed without causing an increase in cost or an increase in weight.

Further, in this embodiment, the ECU 7 is attached to the dash panel 2 in such a manner that the ECU 7 is inclined so that the inner side in the vehicle width direction is located in front of the outer side in the vehicle width direction. A swing axis L1 extending in the direction is set.
Thereby, the upper part of ECU7 can be rock | fluctuated to the vehicle width direction outer side, and the socket 71 of the vehicle width direction inner side surface 7a of ECU7 can be moved to the vehicle width direction outward.
For this reason, the ECU 7 can be swung outward in the vehicle width direction by effectively utilizing the space in front of the ECU 7. For example, when the transmission M is mounted and the rear part of the transmission M is located in front of the lower part of the ECU 7 as in this embodiment, the lower part of the ECU 7 cannot be swung forward, which is particularly effective. is there.

  Therefore, it is possible to effectively use the small space in the engine room E, effectively swing the ECU 7, and allow the operator to easily perform the wiring work of the harness 10.

In this embodiment, the harness lock mechanism 80 is provided in the coupler 11 of the harness 10, and the harness lock mechanism 80 is connected to the socket 71 to a position where the coupler 11 can be visually recognized from the outer position in the vehicle width direction. The ECU 7 is set to swing (see FIG. 3).
Thereby, at the time of the wiring work of the harness 10, the harness lock mechanism 80 can be reliably visually recognized from the outer position in the vehicle width direction, so that the operator can operate while viewing the harness lock mechanism 80.
Therefore, the operator can reliably perform the locking operation of the harness lock mechanism 80, and can eliminate the possibility of incorrect assembly.

In this embodiment, the lock lever 81 of the harness lock mechanism 80 is configured to take different positions in the locked state and the unlocked state.
Thereby, since the lock lever 81 takes different positions in the locked state and the unlocked state, the operator can confirm that the lock lever 81 has been forgotten to be locked at a glance by visually recognizing the position of the lock lever 81.
Therefore, forgetting to lock the harness lock mechanism 80 can be reliably prevented.

In this embodiment, the ECU 7 is disposed on the front side of the master back device 6 at a position below the cowl box 3 extending in the vehicle width direction and at an outer position in the vehicle width direction. The machine M is arranged, the harness 10 is routed toward the front side of the socket 71, and the lock lever 80 of the harness lock mechanism 80 is set to be located on the rear side of the socket 71. .
As a result, the ECU 7 is disposed in a dead space in an engine room E surrounded by large in-vehicle devices such as a cowl box 3 on the upper side, a master back device 6 on the rear side, and a transmission M on the front side. It can be installed in the room E in a compact manner. Further, by arranging the harness 10 on the front side of the vehicle, even if the harness lock mechanism 80 is provided on the rear side of the socket 71, the operator can swing the ECU 7 by swinging the ECU 7. The lock mechanism 80 can be visually recognized from the outer side in the vehicle width direction.
Therefore, it is possible to improve the wiring property of the harness 10 and improve the visibility of the harness lock mechanism 80 while installing the ECU 7 in the engine room E in a compact manner.

In addition, according to the method for assembling the ECU 7 of the present invention, the ECU 7 is mounted on the dash panel 2 in advance via the mounting bracket 20 (S2), and the ECU 7 mounted on the mounting bracket 20 is swung outward in the vehicle width direction.
