Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field)
This relates to a rear lighting device for two wheels.

(Prior Art) Motorcycles require a stop lamp to notify when braking as contact lights, and 7 lash lamps on the left and right to notify the direction of turning. These lights must be placed in a position where they can be easily seen from the rear or from the rear side.

In conventional motorcycles, lamp stays are either built into the rear end of the vehicle body, the rear surface of the rear fender, or the rear end of the seat cowl, or the lamp stays are protruded to the side and attached to the side ends. It was taken.

However, in motorcycles whose outer shell is an air-conditioned monocoque body with open front and rear ends, it is not desirable for lights to protrude from an aerodynamic or external standpoint, and therefore it is desirable to incorporate them somewhere. However, since the monocoque body is formed of panels with a honeycomb sand inch structure and functions as a strength member, it is not desirable to open windows etc. to assemble the lamp housing, and at the same time it is difficult to manufacture. be.

(Problems to be Solved by the Invention) In a motorcycle configured with a monocoque body as an outer shell, it is difficult to install rear lights protruding from an aerodynamic perspective, and it is difficult to assemble the rear lights onto the monocoque body. This invention provides a rear lighting device for two-wheeled motorcycles that is arranged in a location unrelated to the monocoque body without protruding from an aerodynamic or external perspective, and that is easy to see from the rear and rear sides. The purpose is to

[Structure of the invention]

(Means for Solving the Problems) With the above object in mind, the rear lighting device for a two-wheeled motor vehicle of the present invention provides a rear lighting device for a two-wheeled motor vehicle constructed using a hollow monocoque body as an outer shell. To 41!
At the rear end of the placed seat, a combination lamp unit with a stop lamp inside and fludge 11 lamps arranged on both sides is attached to the rear end of the seat bottom plate.

(Function) With this structure, no special molding or processing is required for attaching the light to the monocoque body.
The streamlined appearance can be maintained without complicating the structure of the monocoque body.

The stop lamp and the flasher lamps on both sides are attached to the seat bottom plate as a combination lamp unit.The outer surface is formed in a shape that is continuous with the outer surface of the seat, so they are lined up neatly at the rear edge of the seat, and the flasher lamps are also exposed on the sides, creating a wide space. A visual range of angle can be secured. If the rear end of the seat is shaped to protrude rearward and upward, the light position will be higher, making it even more effective.

Since the rider's center of gravity moves when turning, it is also possible to easily set the seat so that it can be moved left and right.
