By the way, since electronic control has become mainstream in recent vehicles, the number of electronic devices mounted on the instrument panel in front of the driver's seat, such as electronic devices mounted on a meter cluster, is increasing. Accordingly, harnesses for electronic devices are also increasing. Therefore, many harnesses are often bundled with a corrugated tube or the like and routed in the space between the inner surface of the front panel and the back surface of the instrument panel.

Since the insulator is attached to the inner surface of the front panel, the bundle of harnesses is routed so as to avoid the insulator, for example along the edge of the insulator, and is fixed to the inner surface of the front panel.

Each harness must be removed from its routing point for connection to the target electronic device. The position from which the harness is taken out is preferably in the vicinity of the harness connecting portion of the target electronic device. Since the harness is bundled with a corrugated tube or the like and routed so as to avoid the insulator, it is difficult to take out the harness at a position suitable for each electronic device.

In addition, since the insulator attached to the vehicle body panel has a large area, it is desired to improve the mounting accuracy and workability when attaching the insulator to the vehicle body panel.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and aims to improve the degree of freedom in the wiring layout of harnesses in the front part of a vehicle, and to improve the mounting accuracy and workability of insulators to vehicle body panels. .

In such a vehicle front structure, harness clips can be attached by selectively using a plurality of clip holes formed in the plate portion of the cover member. degree improves.
In addition, since the insulator is sandwiched between the cover member and the vehicle body panel, and the flange portion formed on the edge of the plate portion of the cover member holds the insulator in the mounting position, the insulator is mounted on the vehicle body panel. The insulator can be attached using the portion as a guide, and the insulator attachment accuracy is improved, and the insulator attachment workability is improved.

According to the present invention, since a plurality of clip holes into which harness clips can be attached are provided on the surface of the plate portion of the cover member supported by the vehicle body panel, the degree of freedom in wiring layout of the harness is improved. .

This embodiment is merely an example, and is not intended to exclude various modifications and application of techniques not explicitly described in the following embodiments. Each configuration of this embodiment can be modified in various ways without departing from the gist thereof. Also, they can be selected or combined as needed.

[1. Device configuration]
In this embodiment, a truck will be exemplified as the vehicle.
As shown in FIGS. 1(a) and 2(a), a front panel 1 is provided at the front of the vehicle body as a vehicle body panel forming the vehicle body structure. The front panel 1 is arranged above the front end of the floor panel 7 . Although not shown in FIG. 1, a windshield glass 8 is provided above the front panel 1. As shown in FIG.

An insulator 2 having sound insulation and heat insulation properties is attached to the vehicle interior side of the front panel 1 . The insulator 2 of the present embodiment has aluminum foil attached to one surface, but the insulator 2 is not limited to this.
A cover member 3 is attached to the vehicle compartment side of the front panel 1 with an insulator 2 interposed therebetween, and is supported by the front panel 1 .

The cover member 3 is formed in a plate portion 31 whose vehicle-exterior surface contacts the insulator 2, a plurality of clip holes 32 formed in the plate portion 31, and upper and lower edge portions 31a and 31b of the plate portion 31. and flange portions 33, 33 that are formed to bend toward.
The clip hole 32 allows the harness clip 5 to be attached to the surface of the plate portion 31 facing the passenger compartment. Further, the flange portion 33 guides the mounting position of the insulator 2 and holds the mounting position after mounting.

The plate portion 31 of the cover member 3 is formed in a rectangular or substantially rectangular plate shape of a required size according to the shape and size of the insulator 2 , and is mounted on the front end in a substantially vertically upright state like the insulator 2 . Attached to panel 1 . The vertical length of the plate portion 31, that is, the distance between the upper and lower flange portions 33, 33 is set larger than the vertical length of the insulator 2 by the clearance.

In this embodiment, punching metal is used for the cover member 3 . In other words, the plate portion 31 and the flange portion 33 are formed by cutting the punching metal into a predetermined shape and size and bending the required opposite side portions. A large number of holes (in this case, circular holes) are previously formed in the punching metal in a vertical and horizontal direction. It is

A plurality of stud bolts 11 are arranged at required positions on the surface of the front panel 1 facing the passenger compartment and protrude toward the passenger compartment. A plurality of fixing holes 34 are formed therethrough. Here, fixing holes 34 are formed in the vicinity of four corners of a rectangular plate portion 31, respectively, and four stud bolts 11 are provided on the front panel 1 so as to protrude therefrom.

However, the number and arrangement of the stud bolts 11 and the fixing holes 34 are not limited to this, and can be set as appropriate.
Further, if the size of the hole pre-formed in the punching metal matches the outer diameter of the stud bolt 11, the pre-formed hole may be used as it is as the fixing hole 34. If the size of the hole is small, the hole may be enlarged.

The cover member 3 sandwiches the insulator 2 between the cover member 3 and the front panel 1, and engages the stud clips 4 from the passenger compartment side with respect to the stud bolts 11 penetrating through the fixing holes 34, so that the front It is attached to the panel 1 and supported. At this time, by arranging the insulator 2 at a predetermined lateral position between the upper and lower flange portions 33 of the plate portion 31 and attaching the insulator 2, the insulator 2 is automatically positioned in the vertical and horizontal directions. .

When the stud bolt 11 is arranged at a position where it interferes with the insulator 2 to be mounted, a hole through which the stud bolt 11 penetrates may be formed in the main portion of the insulator 2 . Further, when the left and right edges of the plate portion 31 of the cover member 3 are positioned outside the insulator 2 , the stud bolt 11 is arranged at a position avoiding the insulator 2 to prevent the stud bolt 11 from interfering with the insulator 2 . can be prevented.

When the cover member 3 is attached to the front panel 1, as shown in FIGS. 1(b) and 2(b), the plate portion 31 of the cover member 3 faces the passenger compartment side, so that the plurality of clip holes of the plate portion 31 are closed. The harness clip 5 can be selected from among 32 to lock the harness clip 5 in a position suitable for each harness 6 to secure the harness 6 .

As the harness clip 5, for example, an existing one as shown in FIG. 1(c) can be applied. The harness clip 5 illustrated in FIG. 1C is made of resin and includes a plate-shaped base portion 51 and a clip hole 32 projecting from one surface of the base portion 51 and fixed to the clip hole 32 of the cover member 3 on the vehicle body side. and a harness locking portion 53 that is provided on the other surface of the base portion 51 and locks the harness 6 . When applying an existing harness clip, the outer diameter of the clip body 52 is selected to match the inner diameter of the clip hole 32 .

In the example shown in FIG. 1C, the harness locking portion 53 is formed by partially cutting out the annular locking portion 53a, and by elastically deforming the locking portion 53a, the locking portion The harness 6 can be inserted into the inside 53a and the harness 6 can be taken out from inside the locking portion 53a. However, the harness clip 5 is not limited to the one illustrated in FIG.

[2. Action and effect]
With the above configuration, according to the vehicle front structure according to the present embodiment, the cover member 3 is attached to and supported by the front panel 1 with the insulator 2 interposed therebetween. At this time, by arranging the insulator 2 at a predetermined lateral position between the upper and lower flange portions 33 of the plate portion 31 and attaching the insulator 2, the insulator 2 is automatically positioned in the vertical and horizontal directions. . As a result, the mounting accuracy of the insulator is improved, and the workability of mounting the insulator is improved.

In addition, since the insulator 2 is sandwiched between the front panel 1 and the plate portion 31 of the cover member 3 and press-bonded to both, it can be fixed at an appropriate position without using a fixing member such as double-sided tape. Furthermore, since the flange portions 33 formed on the upper and lower edges 31 a and 31 b of the plate portion 31 restrict the vertical movement of the insulator 2 , the insulator 2 is securely fixed to the front panel 1 .

Then, from among the plurality of clip holes 32 formed in the plate portion 31 of the cover member 3 attached to the front panel 1, the clip holes 32 at positions suitable for routing the harness 6 are selected, and the harness clips 5 are attached. By fixing the clip body 52 and locking the harness 6 to the harness locking portion 53 of the harness clip 5, the optimum routing of the harness 6 can be achieved.

FIG. 3 is a sectional view showing the front structure of the vehicle in which the harness 6 is arranged. As shown in FIG. In the space between (including the cover member 3) and the dashboard 9, electronic devices 61 to 63 to which the harness 6 is to be connected are arranged.

Electronic devices 61 such as various meters, passenger airbags, and sensors are arranged in the upper portion of the dashboard 9 . Electronic devices 62 such as a navigation system, audio equipment, an air conditioner control panel, a digital tachograph, and various switches are arranged in the upper and lower intermediate portions of the dashboard 9 . Electronic devices 63 such as an air conditioner unit, various ECUs (Electronic Control Units), and a relay box are arranged in the lower portion of the dashboard 9 .

The power supply side harness 6 connected to a power battery (not shown) is connected to each device side harness 64 of the electronic devices 61 to 63 arranged in the space between the front panel 1 and the dashboard 9, and a connector 65. are connected to each other via

According to this structure, each harness 6 can be routed by selecting the clip hole 32 close to the harness connection point of each electronic device from the plurality of clip holes 32 formed in the plate portion 31 of the bar member 3. can be done. By appropriately using a plurality of clip holes 32, it is not necessary to route a large number of harnesses in a state where they are bundled with a corrugated tube or the like so as to avoid insulators.
Therefore, the degree of freedom in the wiring layout of the harness 6 in the front portion of the vehicle is improved, and the harness 6 can be taken out at positions suitable for the electronic devices 61-63.

The configuration of the above-described embodiment is an example, and can be modified as appropriate without departing from the scope of the present invention.
For example, in the above embodiment, the front structure of a vehicle is applied to a truck, but the front structure may be applied to a vehicle other than a truck.

Further, in the above-described embodiment, the punching metal is used for the cover member 3, but it is also conceivable to use an expanded metal and fix the harness grip to the cover member 3 by using the mesh-like gaps of the expanded metal. . The manufacturing cost of the cover member 3 can be suppressed by using the holes and gaps formed in the existing material as the clip holes 32 for fixing the harness grip. Of course, the cover member 3 may be manufactured by processing the clip hole 32 and the flange portion 33 in a sheet metal plate without holes.

In the above embodiment, the flanges 33, 33 are formed on the upper and lower edges 31a, 31b of the plate portion 31, but the flanges may be formed as necessary. The flange portions may be formed only on the lower edge portion 31b of the plate portion 31, or conversely, the flange portions may be formed on the left and right edges as well as the upper and lower edges 31a and 31b of the plate portion 31.
