Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a headlamp support structure for small vehicles equipped with rod-shaped handles, ie, motorcycles and tricycles.

Prior Art A steering device for a motorcycle or tricycle is integrated with a handle, an upper bridge body (commonly known as a top bridge) that supports the handle and a front fork pipe, and a lower end of a handle rotation shaft that is rotatably inserted into the head pipe. The main components include a lower bridge body (commonly known as a bottom bridge) that supports a front fork pipe together with an upper bridge body. In order to attach a headlight to such a steering device, it is necessary to fix the headlight attachment member to the upper bridge body and/or the lower bridge body by welding or screwing.

Problems to be solved by the invention However, such headlamp mounting members often have a complicated shape, and it is difficult to fix them to the upper bridge body and/or the lower bridge body by welding or screwing. The work is complicated and hinders vehicle assembly work efficiency, and there are problems in that there are a large number of parts.

Means and Effects for Solving the Problems An object of the present invention is to provide a headlamp support structure that is simplified and has a good appearance.

This purpose is to provide a headlamp support piece integrally provided in the center front part of the lower bridge body with a part that protrudes from the upper surface of the lower bridge body, and to make the raised part such that its end surface is connected to the lower end of the head pipe. This is achieved by attaching the headlamp to the headlamp support piece, which has a shape that can come into contact with the handle rotation prevention pieces protruding from both sides of the handle.

According to such a configuration, the upper bridge body and/or
Also, there is no need to assemble a headlamp attachment member to the lower bridge body, and the shape is simplified compared to the conventional one.

Embodiment Hereinafter, an embodiment of the present invention shown in FIGS. 1 to 3 will be described.

FIG. 1 shows a front main part perspective view of a motorcycle, and its steering device 10 includes a handle 12, an upper bridge (hereinafter referred to as the top bridge) 14 that supports the handle 12 and an instrument panel M, A lower bridge (hereinafter referred to as the bottom bridge) 16 and a handle rotation shaft 18 that is integrated with the bottom bridge 16 in an upright manner.
(See FIG. 2) as main members (in the figure, C is a cover that covers the front surface of the bottom bridge 16, and T is a fuel tank). A top bridge 14 and a bottom bridge 16, both of which carry a front fork pipe P at both ends thereof, are integrally connected by a handle rotation shaft 18.

The bottom bridge 16, which is curved in a dogleg shape toward the rear of the vehicle body, is integrally equipped with a headlamp support protrusion 20 at its central front part, and the headlamp support protrusion 20 is located at the front of the bottom bridge 16 and It protrudes upward and is provided with a pair of left and right small protrusions 22 at its rear. This small protrusion 22,2
The respective end surfaces 22A of the handle 30 come into contact with the front surfaces of handle stoppers 42, 42, which will be described later, when the handle 30 is rotated to the left and right critical positions.

Further, a rotation center hole 24 for adjusting the angle of the headlamp 50 described later is provided at the center position in the left and right width direction of the headlamp support protrusion 20, and a circle centered on the rotation center hole 24 is located in front of the rotation center hole 24 for adjusting the angle of the headlamp 50 described later. An arcuate through hole 26 is formed (see FIG. 3).

A headlamp 50 is attached to the headlamp support protrusion 20 having such a structure.
To install the headlight 50, a screw rod 56 fixed to a U-shaped piece 54 which is tiltably connected to a pair of projecting pieces 52 attached to the lower surface of the headlamp 50 with tilting pins 53, 53 is passed through. The screw rod 56 is inserted into the opening 26 and inserted into the rotation center hole 24, and the screw rod 56 is inserted into the through opening 26 within the adjustable angle range θ.
After selecting and determining the appropriate position, the U-shaped piece 54 is fixed to the upper surface of the headlamp support protrusion 20 with a screw rod 56 and a nut 57 in a threaded relationship. In addition, the headlight 50
The attitude of the main body portion of is determined by vertically tilting the tilting pins 53, 53 as fulcrums.

On the other hand, L-shaped handle stops 42, 42 are attached to both sides of the lower end of the head pipe 40 as a vehicle body frame member, and when the handle 30 is rotated to the left or right, the handle stops 42, 42 End face 22A of small protrusion 22 on the front side
comes into contact.

In this way, in the present embodiment, the bottom bridge 16 and the headlamp support protrusion 20 are formed as one piece, so that the shape of the headlamp support protrusion 20 is simplified and the effort required for its assembly can be omitted.
In addition, the number of parts is reduced, and manufacturing costs can be reduced.

Moreover, the small protrusion 2 provided on the headlamp support protrusion 20
Since a structure is adopted in which the maximum steering angle is determined by the contact relationship between the handlebars 2 and 22 and the handle stoppers 42 and 42, there is no need to separately provide a protrusion for determining the maximum steering angle, and the bottom bridge 16
The shape of the top surface is not complicated.

Effects of the invention As is clear from the above explanation, a headlamp support piece having a portion protruding from the upper surface of the lower bridge body is integrally provided at the center front part of the lower bridge body,
The raised portion is shaped so that its end surface can come into contact with handle rotation prevention pieces protruding from both sides of the lower end of the head pipe, and the headlamp is attached to the headlamp support piece. A headlight support structure for a small vehicle is provided.

If such a structure is adopted, there is no need to assemble a separate headlamp support piece to the upper bridge body and/or the lower bridge body, and the headlamp support structure is simplified and the appearance is improved. Cost reductions can be achieved by reducing the number of parts and vehicle assembly work.
