Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a support structure for a dual headlight in a motorcycle or tricycle.

[Conventional technology]

The headlight installation structure of a conventional motorcycle equipped with a pair of headlights, so-called dual headlights, at the front of the vehicle body is as shown in FIG. 3 is provided protruding toward the front of the vehicle body, an oval support frame 4 is provided laterally at the tips of the vibe stays 3, 3, and a pair of heads are attached to a plurality of brackets 5 provided on the inner surface of the support frame 4. Lights 6.6 are arranged side by side with screws 7.

[Problem that the invention seeks to solve]

However, in the above-mentioned system, the length of the pipe stay is required because the vibe stay protrudes from both sides of the vehicle body frame, so a thick wall or large diameter vibe material must be used, and space is required in the width direction of the vehicle body. This created constraints when designing the shape of the steering wheel and the layout of the instruments that would be placed around the steering wheel.

SUMMARY OF THE INVENTION An object of the present invention is to provide a headlight support structure that supports a pair of headlights in a simple and reliable manner, thereby solving the above-mentioned problems.

[Means for solving problems]

The present invention has been made in view of the above-mentioned object, and includes a headlight mounting/pull stay formed of a plate material protruding toward the front of the vehicle body on a head pipe fixed to the front end of the vehicle body frame, and the mounting is carried out on both sides of the stay. It is characterized by supporting a pair of headlights.

[For production]

Therefore, both headlights are supported by cantilevers on both sides of the stay, with the mountings protruding from the center of the front part of the vehicle body.

(Embodiment) An embodiment of the present invention will be explained below with reference to FIGS. m2 to 6.

The motorcycle MIO has main pipe 1 of body frame 11.
A bar handle 1 for controlling a front fork 15 with a front wheel 14 suspended from a head pipe 13 fixed at the front end of the bar handle 1.
A superior wheel 21 is suspended by a rear fork 19 and a rear suspension 20 at the lower part of the seat rail 18, which is rotatably supported by a seat rail 18 that is continuous with the main pipe 12 and whose rear part is supported by a seat rail stay 17. ing.

A fuel tank 22 is disposed above the connection between the main pipe 12 and the seat rail 18, and a tandem seat 23 is disposed above the seat rail 18 at the rear of the tank 22. A side cowl 24 is provided over the rear part.

A V-type engine 27 is mounted between the front wheel 14 and the rear wheel 21 with cylinders 26 and 26 arranged in the front and rear direction by the main pipe 11 and a down tube 25 fixed to the head pipe 13. An air cleaner 29 is installed between the carburetor 28 28 and the fuel tank 22, which are arranged between .26 and the down tube 2.
A radiator 30 is disposed at the front of the vehicle 5, respectively.

An instrument panel 31 and Niga-type headlights 32, 32 are arranged in front of the head pipe 13, and a full cowl extends from the front of the instrument panel 31 and headlights 32, 32 to the lower sides of the engine 27. Figures 3 to 6 show the details of the installation of the headlights 32 and 32, in which the stays 34 that support both headlights 32 and 32 are made of a steel plate with a rectangular cross section. brackets 34b, 34b are integrally formed on both sides of one end 34a, and -ta 34a is connected to the head pipe 13.
A bracket 34a,
34a are supported on both sides of the head pipe 13 by support bolts 35 and 35, respectively.

In addition, on both sides of the other end 34c of the stay 34, which is mounted protruding from the front end side of the vehicle body, there is a 1-shaped upper bracket 36 and a 0-brake bracket 1-37, respectively, and a support bolt 38.
A connecting plate 40 that holds the connecting portions of each headlight 32, 32 in a U-shape between the support pieces 36a, 37a of both brackets 36, 37 that protrude from both sides of the vehicle body.
It is mounted and pivotally supported with support bolts 41 and 42.

Through holes 36b and 37b for inserting support bolts 41 and 42 are coaxially formed in each of the support pieces 35a and 37a of the upper bracket 36 and the lower bracket 37,
Also, the upper bracket 3 is mounted pivotably on the stay 34.
A through hole 36d through which the support bolt 38 is inserted is bored in the piece 36c, and the lower bracket 37 is installed in the piece 3.
7C, a long hole 37d through which the support bolt 39 is inserted is formed in an arc shape with the upper through hole 36d as a fulcrum.

Further, the connecting plate 40 has a support piece 40a having the same shape as the support piece 36a of the upper bracket 36 at the upper part, and a large support piece 40b which protrudes from the support piece 37a of the lower bracket 37 toward the side of the vehicle body at the lower part. , both support pieces 40a, 40b
is integrally supported by support pieces 368.37a of the lower and upper brackets 36.37 by support bolts 41 and 42, and a through hole of the lower bracket 37 is provided in the protruding portion of the support piece 40b of the connecting plate 40. An arc-shaped elongated hole 40c is formed with the fulcrum 37b as a fulcrum, and a support bolt 43 that rotatably supports the headlight 32 is inserted into the elongated hole 40c.

This embodiment is configured as described above, and each headlight 32
When adjusting the optical axis in the lateral direction, loosen the upper and lower support bolts 41, 42, 43, and move the support bolt 43 in the elongated hole 40c using the support bolts 41, 42 arranged on the same axis as a fulcrum. The headlight 32 is rotated left and right under the guidance of The lower bracket 37, which moves under the guidance of the support bolts 39, rotates the headlight 32 up and down to set the desired angle, and then tightens each support bolt again to fix the headlight 32.

Therefore, in both headlights of this embodiment, the mounting projecting from the head vibrator to the front center of the vehicle body is cantilevered to the left and right of the curved end of the stay, and the left and right and top and bottom optical axis adjustments can be made independently. can be done.

In addition, in the above embodiment, the stay for supporting the headlight was explained by bending and forming a single steel plate.
The present invention is not limited to this, and thick plate materials may be used as they are.

(Effects of the Invention) As explained above, in the present invention, a headlight formed of a plate is mounted on a head pipe fixed to the front end of a vehicle body frame by providing a stay projecting toward the front of the vehicle body, and the mounting is carried out on both sides of the stay. Since the pair of headlights are cantilever-supported, the stay length can be shortened and the chain can be made lighter.The number of parts and installation work can also be reduced, and unlike conventional models, space is not required in the width direction of the vehicle body. Because it does not have a handlebar, it is possible to freely design the shape of the handlebar and the layout of the instruments arranged around the handlebar.
