Description

Description: TECHNICAL FIELD The present invention relates to a headlight device for a small vehicle such as a scooter or a tricycle.

[Background Art] For example, small vehicles such as scooters and three-wheeled vehicles are equipped with a handlebar for steering front wheels.

This handlebar is covered with a handle cover, for example, as disclosed in JP-A-63-188584.
In some cases, a headlight is provided on the handle cover, and a lens of the headlight faces a front opening of the handle cover.

[Problems to be Solved by the Invention] By the way, the lens of the headlight facing the opening at the front of the handle cover has its lens surface facing obliquely upward. Therefore, when traveling in rainy weather, rainwater attached to the lens surface of the headlight due to wind pressure from the front flows into the handle cover through a gap between the outer peripheral portion of the lens upper portion and the opening of the handle cover. Sometimes.

The water that has flowed into the handle cover hangs on a lead wire connection portion, a meter device, and the like housed in the handle cover, causing malfunction and rust.

For this reason, it is conceivable to take sufficient waterproof measures for the lead wire connection part and the meter device, or to use means such as sealing the gap between the lens of the headlight and the opening of the handle cover. Cost is required for the sealing structure.

Further, since the lens surface of the headlight is directed obliquely upward, dust easily adheres to the lens surface, which is inconvenient when a small vehicle has to be left outdoors for a long time.

The present invention has been made in view of such circumstances, and rainwater adhering to the lens surface of the headlight falls and hardly penetrates into the handle cover, so that strict waterproof measures are not required.
It is another object of the present invention to provide a headlight device for a small vehicle in which dust does not easily adhere to the lens of the headlight even when left outdoors for a long time.

[Means for Solving the Problems] In order to solve the above problems, the present invention includes a headlight provided on a handle cover that covers a handlebar, and a lens for the headlight is provided in an opening at a front portion of the handle cover. In the small vehicle, the lens surface of the headlight is directed to a diagonally lower running surface.

[Operation] In the present invention, since the lens surface of the headlight facing the opening of the handle cover faces diagonally downward, the rainwater attached to the lens surface of the headlight flows downward from the lens surface. And fall into the handlebar cover.

Also, even if a small vehicle is left outdoors for a long time,
Since the lens surface of the headlight is directed obliquely downward, the dust hardly adheres to the lens surface.

Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

A front wheel 11 is supported by the front fork 10.

The handlebar 2 is a column supported by a steering shaft tube 8.
2a and a handle 2b welded to the upper end of the support 2a and extending toward both sides of the vehicle body. Handle grips 12 are provided at both ends of the handle 2b. Switches 13 near the left and right handle grips 12
Are attached, and brake levers 14, 15 are provided on the left and right sides of the handle portion 2b. The left brake lever 14 activates a mechanical rear brake, the right brake lever 15 activates a hydraulic front brake via a master cylinder 16, and the master cylinder 16 is mounted on the right brake lever 15. It is formed integrally with the part 17.

A speedometer device 18 is attached to a central portion of the handle portion 2b of the handlebar 2, and a flasher control device 19 is attached to the speedometer device 18.
The column from the support 2a of the handlebar 2 to the switches 13 of the handle 2b is covered with a handle cover 20, and the speedometer device 18 and the flasher control device 19 are housed in the handle cover 20.

The handle cover 20 is divided into a front cover 21 that covers the handle bar 2 from the front and a rear cover 22 that covers the handle bar 2 from the rear. The lower mounting portion 22a of the rear cover 22 is mounted on a support lever 23 fixed to the column 2a of the handlebar 2 with screws 24, and the upper mounting portion 22a.
b is attached to a support lever 25 fixed to the handle portion 2b with screws 26, and the attachment portions 22c and 22d are attached to attachment portions 18a and 18b provided on the front side and the rear side of the speedometer device 18 with screws 27,
Installed at 28. The support lever 25 is attached with a screw 46 at the center of the front cover 21.

An opening 29 is formed in the upper part of the rear cover 22, and the display unit 18c of the speedometer device 18 faces the opening 29.

A mounting portion 21a is formed below the front cover 21. The mounting portion 21a is mounted on the lower portion of the rear cover 22 with screws 30. At the center and upper part of the front cover 21
21b, 21c extend rearward, and the mounting portions 21b, 21c are mounted on the rear cover 22 so as to extend forward.
Screws 31 and 32 are attached to f.

An opening 33 is formed on the front side of the front cover 21, and a receiving portion 35 a formed on the housing 35 of the headlight 34 is engaged with a protrusion 21 d formed on the upper inside behind the opening 33. And
The lower portion 35b of the housing 35 of the headlight 34 is attached to the lower portion 21e of the front cover 21 with bolts 36 and nuts 37.

The lens 38 of the headlight 34 is provided so as to face the opening 33, and the lens surface 38a is directed obliquely downward. The lens surface 38 of the lens 38 of the headlight 34
Although a is turned downward, a lens is cut so that the illumination function for the front does not deteriorate.

The rainwater adhering to the lens surface 38a of the lens 38 of the headlight 34 flows down the lens surface 38a, so that the opening 33 of the front cover 21
It hardly flows into the gap 40 between the headlight 34 and the headlight 34, and prevents moisture from entering the handle cover 20.

Therefore, it is possible to reduce the possibility that the lead wire connection portion, the meters, and the like housed inside the handle cover 20 malfunction due to the influence of water and the rust due to the adhesion of water. Also, since the lens surface 38a of the lens 38 of the headlight 34 faces downward, even if the small vehicle is left outdoors for a long time, the lens surface 38a
Dust does not easily adhere to 38a and cleaning is easy.

The housing 35 of the headlight 34 has two curved surfaces 35 for reflection.
c, and the lamp 41 is attached to the center of them. A water shield 43 is provided on an upper portion of the mounting portion 42 of the lamp 41, and the water shield 43 prevents the rainwater that has entered the handle cover 20 from adhering.

A lamp 47 is attached to a housing 45 of the lamp. Like the lens 38 of the headlight 34, the lens 48 of the position lamp 44 is provided so as to face the opening 33, and this lens surface 48a
Is directed diagonally downward. Therefore,
Rain water adhering to the lens surface 48a of the position lamp 44,
Since it flows downward from the lens surface 48a and falls, it is difficult for the lens cover 48 to enter the handle cover 20, and even when left outdoors for a long time, dust is unlikely to adhere to the lens surface 48a.

[Effects of the Invention] As described above, according to the present invention, since the lens surface of the headlight facing the opening of the handle cover faces the obliquely downward running surface, it adheres to the lens surface of the headlight. Rainwater flows down from the lens surface and falls down, making it difficult for it to enter the handle cover.Simple structure prevents internal lead wire connections and meter devices from malfunctioning due to the influence of water. Can be reduced.

Also, even if a small vehicle is left outdoors for a long time,
Since the lens surface of the headlight is directed obliquely downward, the dust hardly adheres to the lens surface, and cleaning is easy.
