[Problems to be solved by the invention]
However, when the electronic unit is arranged, for example, under the passenger seat or in a trunk room, a long wire harness for connecting the electronic unit and the air conditioner is required, and maintenance and inspection are troublesome. .
In recent years, automobiles have been required to make effective use of the surplus space of the vehicle body, and improvements have also been made to the places where the electronic units are arranged.
[0006]
Therefore, an object of the present invention is to solve the above-mentioned problems, and to provide an arrangement structure of an electronic unit that can simplify the structure, facilitate maintenance and inspection, and effectively use the excess space of the vehicle body. is there.
[0007]
[Means for Solving the Problems]
By the way, in recent years, the meter unit arranged in the dash panel of a car has been reduced in thickness by adopting a liquid crystal display device for digitally displaying various displays, or by miniaturizing a movement for displaying analog pointers of various displays. Is progressing.
[0008]
The present inventors have focused on the fact that the surplus space formed conventionally on the backside of the dash panel and being overlooked is becoming a practically usable space as the meter unit becomes thinner, and the present invention Reached.
[0009]
According to the present invention, a plurality of electronic unit boards classified according to functions are stored in an electronic unit storage box provided on the rear side of the meter unit of the vehicle. .
[0010]
In the present invention, since the electronic unit is disposed on the rear side of the meter unit of the vehicle, for example, a wire harness for connecting to an air conditioner can be shortened as compared with the related art, and, for example, the meter unit can be dashed. If the electronic unit is detached from the panel, the electronic unit is exposed to the outside, so that maintenance and inspection such as replacement of the electronic unit board can be easily performed.
In the present invention, the space efficiency of the vehicle body is improved by utilizing the extra space on the back side of the meter unit, which has been overlooked in the past.
[0011]
Further, according to the present invention, a service hole is formed on an upper surface of a dashboard covering an upper portion of the meter unit, and the electronic unit boards are detachably attached via the service hole. It is characterized by the following.
In the present invention, since each electronic unit board can be detached via a service hole formed on the upper surface of the dashboard, the electronic unit can be repaired and inspected without detaching the meter unit from the dash panel. And good workability can be obtained.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of an electronic unit arrangement structure according to the present invention will be described in detail with reference to the drawings.
FIG. 1 shows an arrangement structure 10 of an electronic unit according to an embodiment of the present invention.
[0013]
In FIG. 1, a reinforce 11 is arranged so as to cross the body of an automobile, and a steering shaft 12, a meter unit 13 and a dash panel 14 are supported by the reinforce 11.
A steering column 14 is passed through the steering shaft 12, and a steering wheel 15 is fixed to an end. An electric connection box 16 is arranged below the meter unit 13 along the steering shaft 12.
The meter unit 13 is thinner than the conventional one by adopting a liquid crystal display device for digital display or a small movement for analog pointer display. The electronic unit 17 is arranged between the rear surface 13A of the meter unit 13 and the reinforce 11.
[0014]
The electronic unit 17 includes an electronic unit storage box 17A and a plurality of electronic unit boards 17B stored in the electronic unit storage box 17A.
The electronic unit storage box 17A has a rectangular parallelepiped shape that opens toward the back surface 13A of the meter unit 13. The electronic unit storage box 17A is arranged so that the hand of the worker and the electronic unit board 17B can pass between the electronic unit storage box 17A and the back surface 13A of the meter unit 13. Each electronic unit board 17B is divided according to its function, and can be individually exchanged for the electronic unit storage box 17A.
[0015]
Further, as shown in FIG. 2, inside the dash panel 14, an air conditioning duct 18 (18A, 18B) of the air conditioner and an operation panel 19 for operating the air conditioner via the electronic unit 17 are housed. Is done.
On the other hand, a design panel 20 that covers the periphery of the meter unit 13 and a liquid crystal display panel (not shown) that can display various information is mounted outside the dash panel 14.
The meter unit 13, the steering column 14, the electric connection box 16, the electronic unit 17, and the liquid crystal display panel are electrically connected to each other.
[0016]
As shown in FIG. 3, the dash panel 14 has a lid portion 14A whose upper part is partially detachable.
The lid 14A is configured such that a part of the duct 18A constituting the duct 18 is separated from the ducts 18B and 18B, and is detachable from the dash panel 14 integrally with the lid 14A. Therefore, the opening that appears after the lid 14A is removed is a service hole 21 in which the back surface 13A side of the meter unit is exposed to the outside.
[0017]
In the above-described embodiment, when performing maintenance and inspection of the electronic unit 13, the lid 14 </ b> A is removed from the dash panel 14, and the electronic unit 13 is stored in the electronic unit storage box 17 </ b> A through the upper service hole 21 in the dash panel 14. The plurality of electronic unit boards 17B are detached.
At this time, since the service hole 21 is provided so that the rear surface 13A side of the meter unit 13 is exposed to the outside, it is not necessary to attach and detach the meter unit 13 for maintenance and inspection of the electronic unit 17.
[0018]
According to such an embodiment, since the electronic unit 17 is disposed on the back surface 13A side of the meter unit 13, the wire harness for connecting the meter unit 13, the steering column 14, the electric connection box 16 and the display panel is conventionally provided. In addition, the space efficiency of the vehicle body is improved by effectively utilizing the surplus space on the back surface 13A side of the meter unit 13 which has been overlooked conventionally.
[0019]
According to this embodiment, since each electronic unit board 17B can be freely attached to and detached from the electronic unit storage box 17A through the service hole 13 formed on the upper surface of the dashboard 14, the meter unit 13 can be attached to the dash panel 14 The electronic unit 17 can be repaired and inspected without being detached from the device, and good workability can be obtained.
[0020]
Note that the present invention is not limited to the above-described embodiment, and appropriate modifications and improvements can be made.
In addition, the materials, shapes, dimensions, forms, numbers, arrangement locations, and the like of the meter unit, the electronic unit storage box, the electronic unit board, the dashboard, the service hall, and the like exemplified in the above-described embodiment are those that can achieve the present invention. It is arbitrary and not limited.
[0021]
【The invention's effect】
As described above, according to the present invention, since the electronic unit is disposed on the rear side of the meter unit of the automobile as described in claim 1, for example, a wire harness for connecting to an air conditioner is conventionally used. In addition to the fact that the electronic unit is exposed outside when the meter unit is detached from the dash panel, for example, maintenance and inspection such as replacement of the electronic unit board can be easily performed, and it has been overlooked in the past. By utilizing the extra space on the back side of the meter unit, the space efficiency of the vehicle body is improved.
[0022]
Further, according to the present invention, as described in claim 2, since each electronic unit board is detachable via the service hole formed on the upper surface of the dashboard, the meter unit can be detached from the dash panel without detaching. Repair and inspection of the electronic unit can be performed, and good workability can be obtained.
