Description

[Detailed description of the invention] [Industrial field of application] The invention is applicable to steering handle devices for automobiles,
In detail, the steering wheel is located at the center front of the steering wheel and remains stationary regardless of the rotation of the steering wheel, making it easy to route the wire harness that is electrically connected to the center pad that contains instruments and switches. Regarding equipment.

[Conventional technology and problems]

Reading instruments or operating switches mounted on a car's dash board can be obstructed by the steering wheel, which can cause problems. Various steering wheel devices have been proposed in which a center pad equipped with a steering wheel is disposed in a stationary state regardless of the rotation of the steering wheel.

These conventional techniques include Japanese Patent Publication No. 35-7229, Japanese Utility Model Application Publication No. 53-39934, and Japanese Patent Application Laid-Open No. 1987-39934.
There is a technology described in Publication No. 20531, but the disadvantage is that the structure of the steering device is complicated, there are many parts and support points, and the strength is large. It becomes a structure that is difficult to pull out to the outside,
The disadvantage was that the wiring became long and the wiring work was not easy.

In order to solve these problems, the applicant proposed a steering handle device that has a simple structure and allows for short wiring (Japanese Patent Application Laid-Open No. 1986-1999).
(Refer to No. 292586), but the present invention is a further improvement on this and makes the wiring easier.

[Means for solving problems]

The present invention rotatably supports a steering shaft, which has a pinion fixed to the boss part, inside an outer cylinder that is fixed to a part of the vehicle body and has a boss part at the end, and is pivotally connected to the boss part. An internal gear that meshes with the pinion is fixed to the inner peripheral edge of the steering wheel, and a pad equipped with instruments and switches is supported in a crescent-shaped space formed between the internal gear and the pinion. A support portion was provided to protrude from the boss portion, and a notch recess for wiring a wire harness was provided in the support portion and the boss portion.

[Effect]

With the above configuration, the electrical wires of the pad, which are arranged in front of the steering wheel regardless of the rotation of the steering wheel, can be inserted into the notch recess without the troublesome wiring work of inserting them into the holes as in the past. It becomes possible to connect the connector to an external wire harness that is routed along the cable, which facilitates the wiring work.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, an outer cylinder 1 whose one end is fixed to a part of the vehicle body has a flange-shaped boss part 2 at the other end, and a steering wheel 4 is mounted on the outer peripheral surface of the boss part 2 via a bearing 3. Mounted for free movement.

An internal gear 5 is fitted into the inner peripheral surface of the steering wheel 4, and the internal gear 5 is fixed to the steering wheel 4 with bolts 6.

A bearing 8 that supports the steering shaft 7 is fitted into the inner peripheral surface of the outer cylinder 1 .

One end of the steering shaft 7 has a tapered portion 9
pinion 1 with a similar tapered hole.
0 is attached to the tapered part 9 and fixed to the steering shaft 7 by a nut 11 and key 12, and as shown in FIG. 3, the pinion 10 and the internal gear 5 mesh with each other, and both gears have a A crescent-shaped space 13 indicated by dashed lines
is formed.

This space 13 always maintains a constant shape at a constant position even when the gears 10 and 5 rotate.
It becomes a space that is not interfered with by 5.

A crescent-shaped support portion 14 is provided protrudingly in this space 13 (see FIGS. 2 and 3).

A notch recess 15 is carved in the support part 14 and the boss part 2, and a female connector housing mounting surface 14a is carved in the end face of the support part 14, and a screw hole 16 for connector mounting and a screw hole 17 for pad mounting is formed. is screwed on.

The female connector housing 18 shown in FIG. 2 is provided with flanges 19 on both sides of the distal end, and holes 20 are formed in both flanges 19, respectively.

Further, a male terminal 22 provided at the tip of a wire harness 21 is accommodated at the inner end of the female housing 18 .

The male screw 23 is inserted into the hole 20 of the flange 19 and screwed into the screw hole 16 to fix the flange 19 to the end surface of the support portion.

A pad 24 with instruments and switches arranged on the front has a male connector housing 25 on the rear,
A female terminal 26 provided at the end of an electric wire for instruments and switches is housed in the male connector housing 25, and when the female connector housing 18 is fitted into the male connector housing 25, the female terminal 26 is inserted into the male connector housing 25.
A male terminal 22 is electrically connected to.

The wiring work for the steering handle device configured as described above will be explained.

The male terminal 22 provided at the tip of the wire harness 21 is housed in the female connector housing 18, the female connector housing 18 is inserted into the notch recess 15 of the support part 14, and the flange 19 is inserted into the female connector housing mounting surface of the support part 14. 14 a , the male screw 23 inserted into the hole 20 is screwed into the screw hole 16 to fix the female connector housing 18 to the support portion 14 .

Next, when the pad 24 is attached to the end surface of the support part 14 by screwing a male screw (not shown) into the screw hole 17, the male connector housing 25 of the pad 24 is fitted into the female connector housing 18, and the male The terminals 22 are electrically connected to the female terminals in the male connector housing 25, and the wiring of the wire harness 21 is completed.

In the above explanation, the flange 19 was provided on the female connector housing 18 and fixed to the support part 14.
The female connector housing 18 may be directly fitted into the male connector housing 25 without providing a flange.

〔effect〕

This invention eliminates the troublesome work of routing the wire harness through a hole by providing a notch for wiring the wire harness in the boss and support portion of the steering handle device. It is now possible to connect it to the connector on the pad side and route the cable.

Therefore, the wiring work becomes extremely easy and the wiring can be shortened.
