Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a support structure for a wire harness arranged along a steering shaft of an electric tricycle.

(Prior Art) Referring to FIGS. 4 to 6, a conventional wire harness support structure will be described. 1 is an electric tricycle, 2 is a steering shaft of the electric tricycle 1 (see FIG. 5), 3
Is a handle lever 3 attached to the upper portion of the steering shaft 2. On the steering shaft 2, wires 6 such as an accelerator 4 attached to a handle lever 3 and a brake lever 5, that is, a wire harness 7, is arranged along the steering shaft 2.

These wire harnesses 7 are bound and fixed to the steering shaft 2 by a clamp 8 as shown in FIG. The clamps 8 are attached to the upper and lower parts. The reason why the wires 6 and the like are collectively bound and organized by the clamp 8 in this manner is that no functional problem occurs.

Further, a substantially U-shaped bracket 9 is welded to the steering shaft 2 at two upper and lower positions. The bracket 9 is welded to the front portion of the steering shaft 2 with the head 9a facing forward and the legs 9b facing backward. A steering shaft cover 10 that covers the steering shaft 2 is attached to the bracket 9. The steering shaft cover 10 is composed of a front cover 11 and a rear cover 12. After fixing the front cover 11 to the bracket 9 with the screw 13, the front cover 11 is attached to the rear cover.
12 is attached to cover the entire steering shaft 2.

(Problems to be solved by the invention) In the conventional wire harness support structure having such a configuration,
Although the wire harness is bundled and fixed by using the clamp, the use of the clamp has a problem that the cost is increased. Furthermore, the clamp strongly tightens a very small part of the wire harness, and therefore the wire harness is clamped when the handle is operated. There was a problem that stress was concentrated on the part. Also, if the clamp is removed several times, the lock part may break, and even if the lock part breaks, the wire harness is covered by the cover, so the damaged part cannot be found and it is used as it is. Doing so could damage the wire.

The present invention has been made to solve the above conventional problems.

(Means for Solving the Problems) The present invention provides, as means for solving the above problems,
A wire harness such as a brake lever is arranged along a steering shaft of an electric tricycle, and a bracket having a substantially U-shape is attached to the steering shaft, and the steering shaft covers the entire circumference of the steering shaft and the wire harness on the bracket. In a wire harness support structure with a cover attached, a leg portion of a substantially U-shaped bracket attached to the steering shaft is extended in the longitudinal direction, and the steering shaft is sandwiched by a substantially middle portion of the leg portion of the bracket, The bracket is fixed to the steering shaft, and the steering shaft cover attached to the bracket is vertically split to form a front cover and a rear cover, and the front cover is fixed to the head of the bracket so as to cover the steering shaft. The rear cover is brought into contact with the open end portion of the leg portion of the bracket,
An end of the rear cover is fixed to an end of the front cover, and a wire harness is arranged in a space formed by the rear cover and the left and right extending legs of the bracket. is there.

(Operation) According to the present invention, the leg portion of the bracket having the substantially U-shape is extended in the longitudinal direction, and the bracket is fixed to the steering shaft by sandwiching the steering shaft at the substantially middle portion of the lengthened leg portion. A front cover formed by vertically dividing the steering shaft cover is attached to the head of the fixed bracket to cover the front side of the steering shaft. Further, the rear cover is brought into contact with the open end of the leg of the bracket, and the end of the rear cover is fixed to the end of the front cover to cover the rear side of the steering shaft. Further, a wire harness is disposed in a space surrounded by the rear cover and the left and right extending leg portions of the bracket, and the wire harness is surrounded by the left and right leg portions of the bracket and the rear cover to form a wire harness. Organize without bundling.

(Embodiment) Next, an embodiment of the present invention will be described with reference to FIGS. 4 to 6 showing the conventional technique.
The same members as those shown in the drawings are designated by the same reference numerals, and detailed description thereof will be omitted. FIG. 1 is an enlarged view of the steering shaft 2 and the handle lever 3 of the electric tricycle. In the figure, a substantially U-shaped bracket 14 for attaching the steering shaft cover 10 is attached to the steering shaft 2 with its head 14c facing the front of the vehicle body.

Two brackets 14 are attached to the upper and lower sides of the steering shaft 2, but the lower one has a head 14c that is horizontally long so that two screws 13 can be attached to it, compared to the upper one. And since both have the same legs,
The upper bracket 14 will be described as an example.

The leg portion 14a of the bracket 14 is integrally provided with a leg portion 14b extending in the longitudinal direction of the leg portion 14a, whereby the entire leg portion is formed longer than a normal one.

The bracket 14 is fixed to the steering shaft 2 by welding or the like, with the steering shaft 2 being sandwiched between approximately the middle portions of the long leg portions 14a and 14b. A steering shaft cover 10 that covers the entire outer peripheral portion of the steering shaft 2 is attached to the bracket 14.

The steering shaft cover 10 can be divided vertically, and one of the divided covers is used as a front cover 11 as a bracket 14 as shown in FIG.
The head portion 14c is attached with a screw 13 so as to cover the front side of the steering shaft 2.

Further, as shown in FIG. 3, the other divided cover is used as a rear cover 12, and an inner wall concave portion thereof is brought into contact with an open end portion of a leg portion 14b of the bracket 14 extending from the front cover 11 from the open end portion side. An end of the rear cover 12 is fixed to the end of the steering shaft 2 to cover the rear side of the steering shaft 2.

The rear cover 12 is formed by extending the bracket 14 with legs 14b.
By abutting against, that is, the bracket 14
By extending the leg portion 14b until it comes into contact with the rear cover 12, the leg portion 14b can be used as a reinforcing member for the rear cover.

Left and right legs 14 of bracket 14 mounted in this way
Since the space portion 15 is formed by b, the rear cover 12, and the steering shaft 2, the space portion 15 is used as a passage for the wire 6, and the wire 6 for the accelerator 4 and the brake lever 5, that is, the wire harness 7 is provided in this passage. Is arranged and held.

As shown in FIG. 2, the wiring harness 7 is attached in such a manner that the front cover 11 is attached to the head portion 14c of the bracket 14 and then the wire harness 7 is fitted between the extended leg portions 14b of the bracket 14, As shown in FIG. 3, the inner wall of the rear cover 12 is brought into contact with the open end of the leg portion 14b, and further,
Abutting the end of the rear cover 12 against the end of the front cover 11,
The wire harness 7 is fixed and covered.

Since the wire harness 7 is configured as described above, the wire harness 7 is surrounded by the inner wall of the rear cover 12 and the extending leg portion 14b of the bracket 14, and the wire harness 7 can be bundled and organized without binding.

It should be noted that if the end portions of the portion surrounding the wire harness 7 are chamfered by the extended leg portions 14b of the bracket 14 to perform R finishing, the wire harness 7 will not be damaged.
2 and 3 are views of the upper bracket 14, the leg portions 14b of the lower bracket 14 have the same shape and are omitted.

(Advantages of the Invention) Since the present invention is configured as described above, the clamp for binding the wire harness can be eliminated, the cost increase can be suppressed, and the stress is concentrated on the wire harness. Will disappear. Further, since the clamp is abolished, damage to the wire due to damage to the clamp does not occur. Further, since the wire harness is released at the same time when the steering shaft cover is attached and detached at the time of disassembling the assembly, the number of work steps is reduced.
That is, by removing the rear cover on the open end side of the bracket, the wire harness can be taken out freely, which facilitates maintenance.Also, with the brake lever attached to the tip of the wire, attach the wire harness to the steering shaft. Since it can be arranged, the assembling property can be improved. Furthermore, since the extended leg of the bracket extends to the extent that it comes in contact with the rear steering shaft cover, there is also an effect that it serves as a reinforcing material against pressure from the rear of the cover.
