Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wiring structure for an electric storage mirror for large vehicles, which is attached to a mirror stay protruding from a vehicle body.

[0002]

[Prior Art]

 In recent years, especially in small passenger cars, electric retractable mirrors that can be operated by a switch installed in the driver's seat to adjust the angle of the mirror and store the mirror have become common. Such an electric retractable mirror is also very convenient for large vehicles such as trucks and buses where a large mirror is installed at a position protruding from the vehicle so as to secure a wide indirect view in the blind area. , Is gradually being adopted.

Therefore, a conventional electric storage mirror for a large vehicle will be described with reference to FIGS. 3 to 5. FIG. 3 shows an electric retractable mirror of a general cab over truck, and 1 is a roof panel of the cabin. 2 is a front panel and 3 is a windshield. Reference numeral 4 denotes a mirror stay arm, the upper end of which is connected to the universal joint 5 of the roof panel 1, and the lower end thereof is connected to the pivot shaft 6 of the front panel 2.

Further, a base end portion of the telescopic rod 7 is connected to the front side of the roof panel 2, and this tip end portion is connected to a middle portion of the mirror stay arm 4. The mirror stay arm 4 is provided with mirrors 8a, 8b, 8c for ensuring a rear view, an obliquely downward view, and a view immediately below the cab.

The universal joint 5 is interlocked with a drive unit 9 provided in the lower portion (inside) of the roof panel 2, and the drive unit 9 rotates the mirror stay arm 4 to move the mirrors 8a, 8b, 8c. The included mirror stay arm 4 can be stored in the front part of the windshield 3. Further, as shown in FIG. 4, a vertical rotation drive motor 10a and a horizontal rotation drive motor 10b are provided on the mirror 8a for displaying the rear view so as to remotely adjust the mirror angle. Therefore, in order to supply power to these drive motors 10a and 10b, the harness 11 is wired along the mirror stay arm 4.

[0006]

[Problems to be solved by the device]

 By the way, in the wiring structure of the harness for supplying power to the drive motors 10a and 10b of the mirror 8a, the wiring is provided along the outer surface of the mirror stay arm 4, and the exposed wiring for clipping the key points and the mirror stay. There is an internal wiring that passes through the hollow pipe of the arm 4, and any of the wiring structures has the following problems.

First of all, the problem with the internal wiring structure is that although it looks good, the number of man-hours required for the wiring work is large and it is not suitable for mass-produced vehicles. Moreover, the mirror stay arm 4 must be provided with a through hole necessary for the harness 11 to move in and out, which causes a problem that the strength is locally reduced, and the grommet 12 for ensuring the water tightness of the through hole. (See Fig. 5) and consideration of drainage may be necessary.

On the other hand, to describe the problem of the exposed wiring structure, although it is effective in reducing the number of wiring work steps, it is not preferable in appearance.

Therefore, an object of the present invention is to provide a wiring structure for an electric storage mirror for a large vehicle, which has good workability and good appearance.

[0010]

[Means for Solving the Problems]

 The present invention solves the above-mentioned problems, and is an electric storage for large vehicles that is mounted at a position protruding from the vehicle body via a mirror stay arm, and storage and adjustment of the mirror angle are performed by remote operation of an electric motor. In the wiring structure of the mirror, a hollow part is provided on the baked rubber that has molded the entire circumference of the wiring part of the mirror stay, through which the harness wired along the mirror stay arm is passed. This is a wiring structure for an electric retractable mirror for large vehicles, which is equipped with a harness doorway so that it can be retrofitted from the side.

[0011]

[Action]

 According to the above-mentioned means, the harness of the wiring outside the vehicle along the mirror stay arm can be housed in the hollow portion of the baked rubber and can be wired, so that it is not exposed to the outside. In addition, it can be easily pushed in from the harness entrance and stored, so workability is also good.

[0012]

【Example】

 An embodiment of a wiring structure of an electric storage mirror for a large vehicle according to the present invention will be described with reference to FIGS. 1 and 2. It should be noted that the same parts as those of the related art, such as the electric storage mirror, are denoted by the same reference numerals, and detailed description thereof will be omitted.

In FIGS. 1A and 1B, a mirror 8a for confirming a rear view is a generic name of a drive motor 10 for adjusting a mirror angle (a vertical rotation drive motor 10a and a horizontal rotation drive motor 10b). ), And a harness 11 for supplying power to the drive motor 10 and remotely operating the drive motor 10 is wired along the mirror stay arm 4. As for the outer circumference of the mirror stay arm 4 to which the harness 11 is wired, the entire circumference of the wiring portion shown by hatching in the drawing is molded with a baking rubber 21. The baked rubber 21 is provided with a hollow portion 22 which is continuous substantially parallel to the axial direction of the mirror stay arm 4, and the harness 4 can be housed in the hollow portion 22 for wiring. A harness entrance / exit 23 is provided so that the harness 4 can be retrofitted from the outer peripheral surface side into the hollow portion 22. The harness inlet / outlet 23 is continuous with the hollow portion 22 in the axial direction of the mirror stay 4 and has a lip-shaped cross section so that an opening penetrating from the outer peripheral surface of the baked rubber 21 to the hollow portion 22 can be formed. Two independent projecting pieces 24, 25 are arranged in an overlapping state, and normally the hollow portion 22 is kept in a substantially sealed state. It is preferable that the coating color of the mirror stay arm 4 and the baking rubber 21 be the same color, and the terminal 21a of the baking rubber 21 (the terminal without the hollow portion 22) can be made by gradually thinning the mold.

The operation of the above wiring structure will be described below. The harness 4 that has passed through the inside of the vehicle body and has come out in the vicinity of the lower end portion of the mirror station 4 is stored in the hollow portion 23 by opening the projecting pieces 24 and 25 of the baking rubber 21, and is routed through the hollow portion 23 to the mirror 8a. To be done. The harness 4 housed in the hollow portion 23 is substantially sealed by the two projecting pieces 24 and 25, and is not exposed to the outside except the both ends. Further, the work of storing the harness 4 in the hollow portion 23 can be easily performed on the automobile assembly line, and the exposure of the harness 4 can be minimized.

[0015]

[Effect of the device]

 According to the present invention described above, the wiring of the harness along the mirror stay arm can be easily housed in the assembly line so as not to be exposed to the outside, which is effective in improving the appearance. It is also excellent in terms of workability, cost and reliability, and has the effect of improving the commercialability of large vehicles equipped with electric storage mirrors.
